In the present study a non-motion-stabilized scanning Doppler lidar was operated on board of RV Polarstern in the Arctic (June 2014) and Antarctic (December 2015– January 2016). This is the first time that such a system measured on an icebreaker in the Antarctic. A method for a motion correction of the data in the post-processing is presented.
The wind calculation is based on vertical azimuth display (VAD) scans with eight directions that pass a quality control. Additionally a method for an empirical signal-tonoise ratio (SNR) threshold is presented, which can be calculated for individual measurement set-ups. Lidar wind profiles are compared to total of about 120 radiosonde profiles and also to wind measurements of the ship.
The performance of the lidar measurements in comparison with radio soundings generally shows small root mean square deviation (bias) for wind speed of around 1ms-1(0.1ms-1) and for wind direction of around 10 (1). The post-processing of the non-motion-stabilized data shows comparably high quality to studies with motion-stabilized systems.
Two case studies show that a flexible change in SNR threshold can be beneficial for special situations. Further the studies reveal that short-lived low-level jets in the atmospheric boundary layer can be captured by lidar measurements with a high temporal resolution in contrast to routine radio soundings. The present study shows that a non-motionstabilized Doppler lidar can be operated successfully on an
icebreaker. It presents a processing chain including quality control tests and error quantification, which is useful for further measurement campaigns.
The nonhydrostatic regional climate model CCLM was used for a long-term hindcast run (2002–2016) for the Weddell Sea region with resolutions of 15 and 5 km and two different turbulence parametrizations. CCLM was nested in ERA-Interim data and used in forecast mode (suite of consecutive 30 h long simulations with 6 h spin-up). We prescribed the sea ice concentration from satellite data and used a thermodynamic sea ice model. The performance of the model was evaluated in terms of temperature and wind using data from Antarctic stations, automatic weather stations (AWSs), an operational forecast model and reanalyses data, and lidar wind profiles. For the reference run we found a warm bias for the near-surface temperature over the Antarctic Plateau. This bias was removed in the second run by adjusting the turbulence parametrization, which results in a more realistic representation of the surface inversion over the plateau but resulted in a negative bias for some coastal regions. A comparison with measurements over the sea ice of the Weddell Sea by three AWS buoys for 1 year showed small biases for temperature around ±1 K and for wind speed of 1 m s−1. Comparisons of radio soundings showed a model bias around 0 and a RMSE of 1–2 K for temperature and 3–4 m s−1 for wind speed. The comparison of CCLM simulations at resolutions down to 1 km with wind data from Doppler lidar measurements during December 2015 and January 2016 yielded almost no bias in wind speed and a RMSE of ca. 2 m s−1. Overall CCLM shows a good representation of temperature and wind for the Weddell Sea region. Based on these encouraging results, CCLM at high resolution will be used for the investigation of the regional climate in the Antarctic and atmosphere–ice–ocean interactions processes in a forthcoming study.
This paper tested the ability of Mandarin learners of German, whose native language has lexical tone, to imitate pitch accent contrasts in German, an intonation language. In intonation languages, pitch accents do not convey lexical information; also, pitch accents are sparser than lexical tones as they only associate with prominent words in the utterance. We compared two kinds of German pitch-accent contrasts: (1) a “non-merger” contrast, which Mandarin listeners perceive as different and (2) a “merger” contrast, which sounds more similar to Mandarin listeners. Speakers of a tone language are generally very sensitive to pitch. Hypothesis 1 (H1) therefore stated that Mandarin learners produce the two kinds of contrasts similarly to native German speakers. However, the documented sensitivity to tonal contrasts, at the expense of processing phrase-level intonational contrasts, may generally hinder target-like production of intonational pitch accents in the L2 (Hypothesis 2, H2). Finally, cross-linguistic influence (CLI) predicts a difference in the realization of these two contrasts as well as improvement with higher proficiency (Hypothesis 3, H3). We used a delayed imitation paradigm, which is well-suited for assessing L2-phonetics and -phonology because it does not necessitate access to intonational meaning. We investigated the imitation of three kinds of accents, which were associated with the sentence-final noun in short wh-questions (e.g., Wer malt denn Mandalas, lit: “Who draws PRT mandalas?” “Who likes drawing mandalas?”). In Experiment 1, 28 native speakers of Mandarin participated (14 low- and 14 high-proficient). The learners’ productions of the two kinds of contrasts were analyzed using General Additive Mixed Models to evaluate differences in pitch accent contrasts over time, in comparison to the productions of native German participants from an earlier study in our lab. Results showed a more pronounced realization of the non-merger contrast compared to German natives and a less distinct realization of the merger contrast, with beneficial effects of proficiency, lending support to H3. Experiment 2 tested low-proficient Italian learners of German (whose L1 is an intonation language) to contextualize the Mandarin data and further investigate CLI. Italian learners realized the non-merger contrast more target-like than Mandarin learners, lending additional support to CLI (H3).
Three Kinds of Rising-Falling Contours in German wh-Questions: Evidence From Form and Function
(2022)
The intonational realization of utterances is generally characterized by regional as well as inter- and intra-speaker variability in f0. Category boundaries thus remain “fuzzy” and it is non-trivial how the (continuous) acoustic space maps onto (discrete) pitch accent categories. We focus on three types of rising-falling contours, which differ in the alignment of L(ow) and H(igh) tones with respect to the stressed syllable. Most of the intonational systems on German have described two rising accent categories, e.g., L+H* and L*+H in the German ToBI system. L+H* has a high-pitched stressed syllable and a low leading tone aligned in the pre-tonic syllable; L*+H a low-pitched stressed syllable and a high trailing tone in the post-tonic syllable. There are indications for the existence of a third category which lies between these two categories, with both L and H aligned within the stressed syllable, henceforth termed (LH)*. In the present paper, we empirically investigate the distinctiveness of three rising-falling contours [L+H*, (LH)*, and L*+H, all with a subsequent low boundary tone] in German wh-questions. We employ an approach that addresses both the form and the function of the contours, also taking regional variation into account. In Experiment 1 (form), we used a delayed imitation paradigm to test whether Northern and Southern German speakers can imitate the three rising-falling contours in wh-questions as distinct contours. In Experiment 2 (function), we used a free association task to investigate whether listeners interpret the pragmatic meaning of the three contours differently. Imitation results showed that German speakers—both from the North and the South—reproduced the three contours. There was a small but significant effect of regional variety such that contours produced by speakers from the North were slightly more distinct than those by speakers from the South. In the association task, listeners from both varieties attributed distinct meanings to the (LH)* accent as opposed to the two ToBI accents L+H* and L*+H. Combined evidence from form and function suggests that three distinct contours can be found in the acoustic and perceptual space of German rising-falling contours.
The Firepower of Work Craving: When Self-Control Is Burning under the Rubble of Self-Regulation
(2017)
Work craving theory addresses how work-addicted individuals direct great emotion-regulatory efforts to weave their addictive web of working. They crave work for two main emotional incentives: to overcompensate low self-worth and to escape (i.e., reduce) negative affect, which is strategically achieved through neurotic perfectionism and compulsive working. Work-addicted individuals" strong persistence and self-discipline with respect to work-related activities suggest strong skills in volitional action control. However, their inability to disconnect from work implies low volitional skills. How can work-addicted individuals have poor and strong volitional skills at the same time? To answer this paradox, we elaborated on the relevance of two different volitional modes in work craving: self-regulation (self-maintenance) and self-control (goal maintenance). Four hypotheses were derived from Wojdylo- work craving theory and Kuhl- self-regulation theory: (H1) Work craving is associated with a combination of low self-regulation and high self-control. (H2) Work craving is associated with symptoms of psychological distress. (H3) Low self-regulation is associated with psychological distress symptoms. (H4) Work craving mediates the relationships between self-regulation deficits and psychological distress symptoms at high levels of self-control. Additionally, we aimed at supporting the discriminant validity of work craving with respect to work engagement by showing their different volitional underpinnings. Results of the two studies confirmed our hypotheses: whereas work craving was predicted by high self-control and low self-regulation and associated with higher psychological distress, work engagement was predicted by high self-regulation and high self-control and associated with lower symptoms of psychological distress. Furthermore, work styles mediated the relationship between volitional skills and symptoms of psychological distress. Based on these new insights, several suggestions for prevention and therapeutic interventions for work-addicted individuals are proposed.
We use a novel sea-ice lead climatology for the winters of 2002/03 to 2020/21 based on satellite observations with 1 km2 spatial resolution to identify predominant patterns in Arctic wintertime sea-ice leads. The causes for the observed spatial and temporal variabilities are investigated using ocean surface current velocities and eddy kinetic energies from an ocean model (Finite Element Sea Ice–Ice-Shelf–Ocean Model, FESOM) and winds from a regional climate model (CCLM) and ERA5 reanalysis, respectively. The presented investigation provides evidence for an influence of ocean bathymetry and associated currents on the mechanic weakening of sea ice and the accompanying occurrence of sea-ice leads with their characteristic spatial patterns. While the driving mechanisms for this observation are not yet understood in detail, the presented results can contribute to opening new hypotheses on ocean–sea-ice interactions. The individual contribution of ocean and atmosphere to regional lead dynamics is complex, and a deeper insight requires detailed mechanistic investigations in combination with considerations of coastal geometries. While the ocean influence on lead dynamics seems to act on a rather long-term scale (seasonal to interannual), the influence of wind appears to trigger sea-ice lead dynamics on shorter timescales of weeks to months and is largely controlled by individual events causing increased divergence. No significant pan-Arctic trends in wintertime leads can be observed.
In the context of accelerated global socio-environmental change, the Water-Energy-Food Nexus has received increasing attention within science and international politics by promoting integrated resource governance. This study explores the scientific nexus debates from a discourse analytical perspective to reveal knowledge and power relations as well as geographical settings of nexus research. We also investigate approaches to socio-nature relations that influence nexus research and subsequent political implications. Our findings suggest that the leading nexus discourse is dominated by natural scientific perspectives and a neo-Malthusian framing of environmental challenges. Accordingly, the promoted cross-sectoral nexus approach to resource governance emphasizes efficiency, security, future sustainability, and poverty reduction. Water, energy, and food are conceived as global trade goods that require close monitoring, management and control, to be achieved via quantitative assessments and technological interventions. Within the less visible discourse, social scientific perspectives engage with the social, political, and normative elements of the Water-Energy-Food Nexus. These perspectives criticize the dominant nexus representation for itsmanagerial, neoliberal, and utilitarian approach to resource governance. The managerial framing is critiqued for masking power relations and social inequalities, while alternative framings acknowledge the political nature of resource governance and socio-nature relations. The spatial dimensions of the nexus debate are also discussed. Notably, the nexus is largely shaped by western knowledge, yet applied mainly in specific regions of the Global South. In order for the nexus to achieve integrative solutions for sustainability, the debate needs to overcome its current discursive and spatial separations. To this end, we need to engage more closely with alternative nexus discourses, embrace epistemic pluralism and encourage multi-perspective debates about the socio-nature relations we actually intend to promote.
Avoiding aerial microfibre contamination of environmental samples is essential for reliable analyses when it comes to the detection of ubiquitous microplastics. Almost all laboratories have contamination problems which are largely unavoidable without investments in clean-air devices. Therefore, our study supplies an approach to assess background microfibre contamination of samples in the laboratory under particle-free air conditions. We tested aerial contamination of samples indoor, in a mobile laboratory, within a laboratory fume hood and on a clean bench with particles filtration during the examining process of a fish. The used clean bench reduced aerial microfibre contamination in our laboratory by 96.5%. This highlights the value of suitable clean-air devices for valid microplastic pollution data. Our results indicate, that pollution levels by microfibres have been overestimated and actual pollution levels may be many times lower. Accordingly, such clean-air devices are recommended for microplastic laboratory applications in future research work to significantly lower error rates.
Der Beitrag diskutiert das Verhältnis von allgemeiner und beruflicher Bildung mithilfe einer pädagogischen Theorie der Organisation. Allgemeine Erwachsenen- und berufliche Bildung treffen sich darin, Prozess und Ergebnis der wechselseitigen Auseinandersetzung zwischen Organisationen und Individuen zu sein. Organisationen sind nicht nur Kontext von Bildung, sie sind selber gebildet und wirken pädagogisch. Der Beitrag erschließt die Funktion und Eigenlogik der Organisation in ihrem Verhältnis zu den Grundbegriffen der Erziehungswissenschaft. Der Vorschlag ermöglicht es, Lernen, Sozialisation, Erziehung, Bildung und Kompetenz in ihrer Geltung für die ineinander verflochtene Strukturdynamik von Organisation und Subjekt zu differenzieren. Als Alternative zur geläufigen Organisationsvergessenheit der Pädagogik integriert die differenzierende Ordnung dieser Begriffe eine erziehungswissenschaftliche Perspektive auf Individuum und Organisation.
Digitalization primarily takes place in and through organizations. Despite this prominent role, however, the importance of organizational structure-building processes in the digital transformation is still underexposed in discourse. The fact that ongoing digitalization is linked to an established phenomenon and its own logic, is regularly not addressed due to the attraction potential of the semantics of the digital revolution. Digital revolution and the reordering of societal relationships, though, manifest themselves primarily in processes of reorganization. Structural automation processes in the ongoing digital transformation are limiting the scope for action, necessitating forms of structural structurelessness in organizations that cultivate opportunities for chance. Since organizations realize their operations as a dual of structure and individual, and the principle of organization is therefore based on the complementarity of structural formality and unpredictable informality. The paper discusses the topicality of the classical form of modern organization in the digital age and reflects on approaches to a contemporary design of spaces of opportunity. The reflexive handling of future openness is the central task of management and leadership in order to enable variation and innovation in organizations.
Roof and wall slates are fine-grained rocks with slaty cleavage, and it is often difficult to determine their mineral composition. A new norm mineral calculation called slatecalculation allows the determination of a virtual mineral composition based on full chemical analysis, including the amounts of carbon dioxide (CO2), carbon (C), and sulfur (S). Derived norm minerals include feldspars, carbonates, micas, hydro-micas, chlorites, ore-minerals, and quartz. The mineral components of the slate are assessed with superior accuracy compared to the petrographic analysis based on the European Standard EN 12326. The inevitable methodical inaccuracies in the calculations are limited and transparent. In the present paper, slates, shales, and phyllites from worldwide occurrences were examined. This also gives an overview of the rocks used for discontinuous roofing and external cladding.
This study investigated correlative, factorial, and structural relationships between scores for ability emotional intelligence in the workplace (measured with the Geneva Emotional Competence Test), as well as fluid and crystallized abilities (measured with the Intelligence Structure Battery), carried out by a 188-participant student sample. Confirming existing research, recognition, understanding, and management of emotions were related primarily to crystallized ability tests measuring general knowledge, verbal fluency, and knowledge of word meaning. Meanwhile, emotion regulation was the least correlated with any other cognitive or emotional ability. In line with research on the trainability of emotional intelligence, these results may support the notion that emotional abilities are subject to acquired knowledge, where situational (i.e., workplace-specific) emotional intelligence may depend on accumulating relevant experiences.
The changing views on the evolutionary relationships of extant Salamandridae (Amphibia: Urodela)
(2018)
The phylogenetic relationships among members of the family Salamandridae have been repeatedly investigated over the last 90 years, with changing character and taxon sampling. We review the changing composition and the phylogenetic position of salamandrid genera and species groups and add a new phylogeny based exclusively on sequences of nuclear genes. Salamandrina often changed its position depending on the characters used. It was included several times in a clade together with the primitive newts (Echinotriton, Pleurodeles, Tylototriton) due to their seemingly ancestral morphology. The latter were often inferred as a monophyletic clade. Respective monophyly was almost consistently established in all molecular studies for true salamanders (Chioglossa, Lyciasalamandra, Mertensiella, Salamandra), modern Asian newts (Cynops, Laotriton, Pachytriton, Paramesotriton) and modern New World newts (Notophthalmus, Taricha). Reciprocal non-monophyly has been established through molecular studies for the European mountain newts (Calotriton, Euproctus) and the modern European newts (Ichthyosaura, Lissotriton, Neurergus, Ommatotriton, Triturus) since Calotriton was identified as the sister lineage of Triturus. In pre-molecular studies, their respective monophyly had almost always been assumed, mainly because a complex courtship behaviour shared by their respective members. Our nuclear tree is nearly identical to a mito-genomic tree, with all but one node being highly supported. The major difference concerns the position of Calotriton, which is no longer nested within the modern European newts. This has implications for the evolution of courtship behaviour of European newts. Within modern European newts, Ichthyosaura and Lissotriton changed their position compared to the mito-genomic tree. Previous molecular trees based on seemingly large nuclear data sets, but analysed together with mitochondrial data, did not reveal monophyly of modern European newts since taxon sampling and nuclear gene coverage was too poor to obtain conclusive results. We therefore conclude that mitochondrial and nuclear data should be analysed on their own.
Phylogeographic analyses point to long-term survival on the spot in micro-endemic Lycian salamanders
(2020)
Lycian salamanders (genus Lyciasalamandra) constitute an exceptional case of microendemism of an amphibian species on the Asian Minor mainland. These viviparous salamanders are confined to karstic limestone formations along the southern Anatolian coast and some islands. We here study the genetic differentiation within and among 118 populations of all seven Lyciasalamandra species across the entire genus’ distribution. Based on circa 900 base pairs of fragments of the mitochondrial 16SrDNA and ATPase genes, we analysed the spatial haplotype distribution as well as the genetic structure and demographic history of populations. We used 253 geo-referenced populations and CHELSA climate data to infer species distribution models which we projected on climatic conditions of the Last Glacial Maximum (LGM). Within all but one species, distinct phyloclades were identified, which only in parts matched current taxonomy. Most haplotypes (78%) were private to single populations. Sometimes population genetic parameters showed contradicting results, although in several cases they indicated recent population expansion of phyloclades. Climatic suitability of localities currently inhabited by salamanders was significantly lower during the LGM compared to recent climate. All data indicated a strong degree of isolation among Lyciasalamandra populations, even within phyloclades. Given the sometimes high degree of haplotype differentiation between adjacent populations, they must have survived periods of deteriorated climates during the Quaternary on the spot. However, the alternative explanation of male biased dispersal combined with a pronounced female philopatry can only be excluded if independent nuclear data confirm this result.
Advances in eye tracking technology have enabled the development of interactive experimental setups to study social attention. Since these setups differ substantially from the eye tracker manufacturer’s test conditions, validation is essential with regard to the quality of gaze data and other factors potentially threatening the validity of this signal. In this study, we evaluated the impact of accuracy and areas of interest (AOIs) size on the classification of simulated gaze (fixation) data. We defined AOIs of different sizes using the Limited-Radius Voronoi-Tessellation (LRVT) method, and simulated gaze data for facial target points with varying accuracy. As hypothesized, we found that accuracy and AOI size had strong effects on gaze classification. In addition, these effects were not independent and differed in falsely classified gaze inside AOIs (Type I errors; false alarms) and falsely classified gaze outside the predefined AOIs (Type II errors; misses). Our results indicate that smaller AOIs generally minimize false classifications as long as accuracy is good enough. For studies with lower accuracy, Type II errors can still be compensated to some extent by using larger AOIs, but at the cost of more probable Type I errors. Proper estimation of accuracy is therefore essential for making informed decisions regarding the size of AOIs in eye tracking research.
Evaluation of an eye tracking setup for studying visual attention in face-to-face conversations
(2021)
Many eye tracking studies use facial stimuli presented on a display to investigate attentional processing of social stimuli. To introduce a more realistic approach that allows interaction between two real people, we evaluated a new eye tracking setup in three independent studies in terms of data quality, short-term reliability and feasibility. Study 1 measured the robustness, precision and accuracy for calibration stimuli compared to a classical display-based setup. Study 2 used the identical measures with an independent study sample to compare the data quality for a photograph of a face (2D) and the face of the real person (3D). Study 3 evaluated data quality over the course of a real face-to-face conversation and examined the gaze behavior on the facial features of the conversation partner. Study 1 provides evidence that quality indices for the scene-based setup were comparable to those of a classical display-based setup. Average accuracy was better than 0.4° visual angle. Study 2 demonstrates that eye tracking quality is sufficient for 3D stimuli and robust against short interruptions without re-calibration. Study 3 confirms the long-term stability of tracking accuracy during a face-to-face interaction and demonstrates typical gaze patterns for facial features. Thus, the eye tracking setup presented here seems feasible for studying gaze behavior in dyadic face-to-face interactions. Eye tracking data obtained with this setup achieves an accuracy that is sufficient for investigating behavior such as eye contact in social interactions in a range of populations including clinical conditions, such as autism spectrum and social phobia.
This paper describes the concept of the hyperspectral Earth-observing thermal infrared (TIR) satellite mission HiTeSEM (High-resolution Temperature and Spectral Emissivity Mapping). The scientific goal is to measure specific key variables from the biosphere, hydrosphere, pedosphere, and geosphere related to two global problems of significant societal relevance: food security and human health. The key variables comprise land and sea surface radiation temperature and emissivity, surface moisture, thermal inertia, evapotranspiration, soil minerals and grain size components, soil organic carbon, plant physiological variables, and heat fluxes. The retrieval of this information requires a TIR imaging system with adequate spatial and spectral resolutions and with day-night following observation capability. Another challenge is the monitoring of temporally high dynamic features like energy fluxes, which require adequate revisit time. The suggested solution is a sensor pointing concept to allow high revisit times for selected target regions (1"5 days at off-nadir). At the same time, global observations in the nadir direction are guaranteed with a lower temporal repeat cycle (>1 month). To account for the demand of a high spatial resolution for complex targets, it is suggested to combine in one optic (1) a hyperspectral TIR system with ~75 bands at 7.2"12.5 -µm (instrument NEDT 0.05 K"0.1 K) and a ground sampling distance (GSD) of 60 m, and (2) a panchromatic high-resolution TIR-imager with two channels (8.0"10.25 -µm and 10.25"12.5 -µm) and a GSD of 20 m. The identified science case requires a good correlation of the instrument orbit with Sentinel-2 (maximum delay of 1"3 days) to combine data from the visible and near infrared (VNIR), the shortwave infrared (SWIR) and TIR spectral regions and to refine parameter retrieval.
Politische Leitlinien Graf Heinrichs (1288-1304) 1.Phase: 1288-1297 Während der Konsolidierungsphase nach der desaströsen Niederlage zu Worringen (1288-1297) galt es, die bestehenden Herrschaftsrechte der Grafschaft zu sichern, zumal der junge Graf noch minderjährig war. Als politische Maßnahmen und Verhaltungsmaximen während dieser Phase sind hervorzuheben: 1) die Hochzeit des jungen Grafen mit einer Tochter des Siegers von Worringen, des Herzogs von Brabant, 2) Doppelvasallität zum deutschen und französischen König infolge eines Fidelitätsvertrages mit König Philipp von Frankreich. Diese Doppelvasallität ermöglichte politischen Attentismus, Neutralität im englisch/deutsch - französischen Krieg. Die Verpflichtung zur Verteidigung des französischen Königreiches fiel wegen der expansiven Politik König Philipps nicht ins Gewicht. Doppelvasallität verschafft außerdem Rückendeckung bei künftigen regionalen Konflikten, begünstigt politisches Lavieren zwischen den Königsherrschaften ohne sich deren Gegnerschaft einzuhandeln. 3) eine konservative zur Rechtsbewahrung und mit Rechtsansprüchen untermauerte Grundhaltung. Sie sichert zunächst nicht nur die bestehenden Herrschaftsrechte ab sondern schafft zugleich die Grundlage expansiver Politikmöglichkeiten hinsichtlich historischer Rechte mit einer Alternativen im Gefolge: a) die diplomatische Konfliktlösung, b) die kriegerische, gewaltsame Entscheidung. 2.Phase: 1298 - 1304 X 10 Reichspolitische Vorgänge aktivieren Phase 1.3), eine expansive politische Zielsetzung und deren Beendigungsprozeß. Doppelvasallität schließt Krieg oder auch Parteinahme gegen einen der Könige oder für den einen gegen den anderen König in der Regel aus, aber der deutsche Thronstreit zwischen Adolf von Nassau und Albrecht von Habsburg schuf eine besondere Ausgangslage mit Möglichkeiten und Risiken, die es gegenseitig abzuwägen galt. Graf Heinrichs Parteinahme für den gewählten Gegenkönig Albrecht von Habsburg würde ihm, bei einem Sieg Albrechts, eine neue politische Perspektive im Rahmen seiner Doppelvasallität eröffnen, die ihm wegen des politischen Gegensatzes beider Könige bisher zur Neutralität, zum Attentismus zwang. Jetzt würde ihm bei beiderseitigem königlichem Einvernehmen ein politischer Handlungsspielraum möglich sein mit gestärktem Rückhalt bei den Königen. Das Risiko einer Niederlage des Gegenkönigs konnte er eingehen, denn dann bliebe ihm immer noch der Rückhalt im französischen Königtum. Die auf der Seite König Adolfs stehenden Trierer nutzten die Abwesenheit des zur Entscheidungsschlacht bei Göllheim abgerückten Grafen, um in dessen Grafschaft einzufallen und dabei einen Zollturm auf einer Moselinsel unterhalb Grevenmachers zu zerstören, da sie die Rechtmäßigkeit der dortigen Geleitzollerhebung bestritten. Diese Provokation entschied darüber, wo Graf Heinrichs "neue Politik" nach dem Sieg Albrechts von Habsburg ansetzen, gegen wen sie sich richten würde - gegen Trier. Aber der Graf geht diplomatisch geschickt vor, reagiert nach seiner Rückkehr erstaunlich konziliant, befreit die Bürger durch Vermittlung des Grafen von Looz von der Geleitzollerhebung bei Grevenmacher, akzeptiert folglich deren Behauptung, die Zollerhebung sei unrechtmäßig erfolgt, jedoch mit einem Hintergedanken: Im Gegenzug erwartet er von den Bürgern ebenfalls Entgegenkommen, die Anerkennung einer jährlichen vogteilichen Abgeltungssteuer, was die Trierer, die ja mit dem Recht argumentierten, wohl schlecht verweigern könnten. Jedoch gingen die Bürger hierauf nicht ein. Ein weit hergeholter, aus dem Archiv des Grafen hervorgekramter verstaubter "alter Vertrag", bereits 1140/47 nicht mehr aktuell, hätte jetzt keine Gültigkeit mehr, werde daher nicht anerkannt! - Waren zuvor die Zöllner Graf Heinrichs auf der Moselinsel die "Wegelagerer", wie die "Gesta Trevirorum" formulieren, so waren jetzt die Trierer die "Bösewichte"! Mit einer ablehnenden Antwort dürfte Graf Heinrich freilich gerechnet haben, denn der Hintergedanke ließ sich weiter spinnen: Der Graf beschied sich nicht mit der negativen Antwort und begann einen Krieg mit den Trierern, vordergründig um sie zur Vertragstreue, Zahlung der 300 lb. jährlich zu zwingen, tatsächlich jedoch um die vor dem Abschluß des "alten Vertrages" bestandene vogteiliche Suprematie zurückzugewinnen! - Nichtentrichtung der 300 lb. jährlich bedeutet Rückfall in den vorvertraglichen Zustand! - Damit vollzog Graf Heinrich den Übergang von der Konsolidierungs- zur Expansionsphase, sich mit der Stadt und zugleich deren Erzbischof anlegend, mit dem Argument eines weit hergeholten Rechtsanspruchs aber mit politischem Rückhalt bei den Königen. Diese 2.Phase sollte allerdings nur von kurzer Dauer sein. Der Feldzug des Jahres 1300 gegen Trier scheiterte als die zur Verstärkung entsandten Truppen König Albrechts unter dem Kommando des märkischen Grafensohnes nach Weisung des Königs die Belagerung der Stadt abbrachen und nach Köln abzogen, mit folgenreichen politischen Konsequenzen für Graf Heinrich: Ab diesem Moment galt das Bündnis mit König Albrecht als beendet und somit auch die vorgezeichnete politische Linie des gemeinsamen Vorgehens gegen den Grafen von Hennegau, als erstes dem unmittelbar bevorstehenden Zug nach Nimwegen, wohl in Konsequenz auf Kosten einer Entfremdung mit König Philipp, dem politischen Rückhalt des Grafen von Hennegau. Noch gab Graf Heinrich seine Expansionsabsichten gegen Trier nicht auf, ein Umsturzversuch dem Luxemburger Grafenhaus nahestehender Kreise der Bürgerschaft scheiterte hauptsächlich am Widerstand der Handwerkerzünfte, denen der Erzbischof die Einberufung eines Rates der "consules" zugestand. Jetzt erst resignierte der Graf und ging zu einer Verständigungspolitik über. Bemerkenswert, wie er sich nach den Mißerfolgen, salopp formuliert, "aus der Affaire zog". Zunächst signalisierte er die Absicht, auf seine vogteilichen Ambitionen zu verzichten, begrüßt von Erzbischof und Stadt, und bot stattdessen eine Einungspolitik an, auf die Erzbischof und Stadt bereitwillig eingingen. Die Putschisten wurden rehabilitiert, der vorherige Einfluß des Grafen in der Stadt wiederhergestellt unter der Bedingung, daß die neue Ratsverfassung anerkannt wird. Er akzeptiert den von Erzbischof Dieter gegen ihn einberufenen, zumindest von diesem zugelassenen neuen Stadtrat, der seine Ambitionen letztlich zunichte gemacht hatte, revanchiert sich jedoch gegenüber Dieter, indem er im Anschluß an den Einungspakt mit den Bürgern einen Sondervertrag abschließt, die Bürger davon überzeugt, daß die vogteiliche Abgeltungssteuer der 300 lb. jährlich auch für sie vorteihaft sein werde. Er erinnert die Bürger an deren Bedeutung, daß derjenige, der sie entrichtet, sich im Besitz vogteilicher, letztendlich im Königtum verankerter Herrschaftsrechte befindet, er dabei ihre Bedenken zerstreut, indem er Bürger der Stadt zu werden verspricht und so eine Erneuerung vogteilicher Ansprüche ausschließt, und daß er in seiner Eigenschaft als Mitbürger sie und ihre Rechte gegen Anfechtungen erzbischöflicherseits zu verteidigen gedenkt. Die Stadt akzeptiert sein Angebot mit dem Vertrag vom 2.4.1302 und präsentiert sich im Vertrag vom 2.9.1304 mit Erzbischof Dieter als Inhaber der Vogtei, indem sie Dieter 300 Bewaffnete bedingt zur Verfügung stellt. Seiner Einungslinie und Bündnispolitik bleibt Graf Heinrich auch bei neuerlichen "hausgemachten" Bürgerunruhen treu, und er wirkt bei der Vollendung der Einung mit, indem die Fehde zwischen der Stadt und Daun/Praudom mit seiner Hilfe beendet wird. 3.Phase: 1301 II 9 - 1304 kurz nach VIII 21/(1305 VII) Der Entschluß, am Abwehrkampf der Flamen gegen die französische Invasion aktiv teilzunehmen fiel Graf Heinrich trotz seiner Bündnisse mit dem flämischen Grafenhaus nicht leicht. Er hielt sich im Jahre 1302 noch im Hintergrund, nahm nicht an der Schlacht bei Courtrai ("Güldensporenschlacht") teil. Könige sollten nicht bekämpft werden sondern vielmehr politischen Rückhalt in territorialpolitischen Auseinandersetzungen gewähren. Das Territorium des französischen Königreiches sollte vertragsgemäß gegen Angreifer verteidigt werden aber auch Flandern und das ihm persönlich nahestehende flämische Grafenhaus, mit dem er am 9.Februar 1301 ein erstes Bündnis abschloß. Die Kriegsziele gaben den Ausschlag, sodaß er sich für die Verteidigung Flanderns und des flämischen Grafenhauses entschied, ohne damit gegen die mit König Philipp abgeschlossenen Verträge zu verstoßen, selbst als er mit den Flamen im August/September 1303 bei der Abwehr einer bereitstehenden französischen Invasionsarmee unter König Philipp diesem bis vor die Tore von Paris folgte. Hierfür entschuldigte er sich gewissermaßen anschließend bei dem König, indem er seine Parteinahme mit seiner Feindschaft gegen den mit dem König verbündeten Grafen von Hennegau zu begründen sucht und bittet hier um eine Vermittlung Philipps, um sich in Zukunft zumindest neutral verhalten zu können. Dem Kriegszug folgt eine Phase des Attentismus, des Abwartens bis zu einem Verhandlungsergebnis (1.10.1303-15.3.1304), danach die Waffenstillstandsphase zwischen ihm und dem Grafen von Hennegau (15.3.1304-18.8.1304),während der er seine flämischen Allianzver- pflichtungen ruhen läßt. Ein zweifellos mit Erleichterung angenommener Auftrag König Philipps nach der Schlacht bei Mons-en-Pévèle, Friedensverhandlungen in die Wege zu leiten, entbindet den Grafen von der erneut eingeforderten flämischen Bündnisverpflichtung. Wie der chronologische Ablauf ausweist, haben zwischen den Phasen des "Schauplatz Trier" und des "Schauplatz Flandern" Interferenzbeziehungen bestanden. Das Bündnis Graf Heinrichs mit der flämischen Grafenfamilie von jenem 9.Februar 1301 und die Vorkommnisse in und um Flandern haben neben dem Mißerfolg bei der Belagerung Triers und dem gescheiterten Putsch sicherlich zum Politikwechsel Graf Heinrichs gegenüber Trier ihren Teil beigetragen. Gleichzeitig an zwei politischen Brennpunkten wollte und konnte er nicht mit gleichem Nachdruck präsent sein.
Das Judenschutzprivileg Karls d. Gr. setzte voraus, daß den Juden eine die Königsherrschaft bzw. den Staat stützende Funktion zugedacht war. Damit vollzog der Kaiser eine Wende um 1800 gegenüber den antiken Herrschern, die in den Juden eine Gefahr für ihren zentralisierten Einheitsstaat erblickt hatten. Unter dem Dach des von Kaiser Karl begründeten Judenschutzes lebte das traditionelle politische Motiv einer sich in zahlreichen Repressionen bis hin zu Verfolgungen und Vertreibungen äußernden Judenfeindschaft im nordalpinen Raum weiter, modifiziert infolge geänderter Voraussetzungen. Die Juden fanden sich hinfort in einem politischen Spannungsfeld zwischen Judenschutz und Anfeindung eingebunden und zwar innerhalb eines sich horizontal zunächst bipolar (Rivalität Kaiser/König - Papst), dann auch multipolar ausweitenden Herrschaftsbereiches mit zum Teil rivalitätsbedingten Übergriffen bis hin zu Verfolgungen.- Wegen der Beteiligung anderer Gewalten neben dem König an der Herrschaft über die Juden und damit an der Ausübung des Judenschutzes wurden die Juden oftmals Leidtragende separater materieller und politischer Konflikte, weil sie politisch als Stütze konkurrierender bzw. einander verfeindeter Herrschaftsträger wahrgenommen wurden, womit eine der Modifikationen des traditionellen Motivs faßbar wird - die Gefährdung eigener Herrschaftspositionen durch den politischen Widersacher. Folgt man dem Ritter und Ministerialen Johann von Rinberg als Leitfigur - 1298 wird er dann definitiv zur Hauptfigur -, erschließt sich ein neuer bisher in der Forschung vernachlässigter Täterkreis - die Rolle der Ministerialen bei Judenverfolgungen gerät in den Focus der Aufmerksamkeit und nicht der Mob, die blind wütende, die Juden mit oder ohne pseudoreligiösem Bezug kriminalisierende und lynchende Masse, sondern vielmehr die Frage nach den Drahtziehern bzw. Strippenziehern im Hintergrund, den Hintermännern der stereotyp wiederkehrenden Standardbeschuldigungen (Brunnen- vergiftung, Hostienfrevel, Ritualmord,...). Der im Rheingau gelegene Salhof Lorch entpuppte sich als das Zentrum ministerialischer Opposition unter Führung des Rheingrafen gegen den Ausbau der Landesherrschaft des Mainzer Erzbischofs. Hier in Lorch selbst veranlaßten die Ministerialen während eines "Krieges" gegen den Erzbischof Werner von Mainz ihre erste Judenverfolgung im Jahre 1274/5, worin auch die Familie der Rinbergs involviert war. In den Verhandlungen eines Schiedsgerichts wird die von den Ministerialen eingeschlagene Taktik erkennbar, ihre Verantwortung und Mitschuld zu verschleiern und die Schuld ausschließlich den eigentlichen Judenschlägern anzulasten, was freilich nicht ganz gelingt, da der Erzbischof auf vollem Schadenersatz bestand, den die ärmeren Judenschläger selbst nicht zu leisten vermochten. Mit dem Sieg des Erzbischofs 1279 in der Schlacht bei Gensingen gegen die Ministerialität unter Führung des Rheingrafen und seinem Sieg auch in der sich anschließenden "Sponheimer Fehde" des Jahres 1281 kam die Wende auch für die Truchsessenfamilie von Rinberg. Ihre und des Rheingrafen Burg Rheinberg im Wispertal wurde 1281 erobert und zerstört und das Truchsessenamt ihnen entzogen. Sigfrid von Rinberg und sein Sohn Johann gerieten nicht wie der Rheingraf und dessen Sohn in Gefangenschaft, sie konnten sich ihr durch die Flucht entziehen, unterwarfen sich nicht und wurden von nun an ausdrücklich als "Feinde" des Erzbischofs und der Mainzer Kirche bezeichnet. Der Rheingraf wurde aus dem Rheingau verdrängt und mußte sich verpflichten, keine konspirativen Kontakte zu diesen Feinden aufzunehmen bzw. zu pflegen, sie nicht zu beherbergen. Gleiches galt natürlich auch für die unterworfene Ministerialität. Indizien legen den Schluß nahe, daß sich Johann von Rinberg zwischen 1281 und 1292 in Reichweite des Salhofes Lorch aber dennoch an einem sicheren Ort aufhielt, in der Reichsstadt Oberwesel. Von hier aus ließen sich durch ihn als erklärtem Feind des Erzbischofs hervorragend konspirativ Verbindungen knüpfen und koordinieren. Die Ministerialenopposition lebte im Verborgenen wieder auf. Gesucht wurde nach Wegen, scheinlegal im Zusammenspiel mit dem verbündeten Mainzer Stadtrat gegen Positionen des Erzbischofs - hier gegen dessen Juden - vorzugehen. So kann es nicht verwundern, daß diesesmal der nächste Vorstoß gegen die Juden 1282/3 nicht von Lorch her sondern von Olm aus erfolgte durch den Ritter und Ministerialen Herbord Ring von Olm, der bezeichnenderweise enge Verbindungen zum Salhof Lorch unterhielt, der jetzt in Begleitung weiterer Ministerialen vor der Stadt Mainz erschien, um wegen der Ermordung angeblich seines Neffen und angeblich durch Juden der Stadt Mainz Einlaß zu begehren und eine ordentliche Gerichtsverhandlung zu verlangen. Das Komplott des Herbord im Zusammenspiel mit dem Mainzer Stadtrat, der danach trachtete, den Judenschutz und die Gerichtsbarkeit über die Juden zu gewinnen, wurde von Erzbischof Werner von Anfang an durchschaut. Eine "kleine", vom Stadtrat kontrollierte und beendete Judenverfolgung wurde wie schon 1281 zugelassen, um so das Unvermögen des Judenschutzes durch den Erzbischof offenkundig zu machen. 1287 transportierten Ministerialen den zu Oberwesel angeblich von dortigen Juden ermordeten "Guten Werner" per Schiff gen Mainz, um so das Schauspiel des Herbord von Olm aus dem Jahre 1282/3 zu wiederholen. Eine Koordination muß der Übernahme vorausgegangen sein, eingefädelt wurde der Fall sehr wahrscheinlich durch ihren externen Komplizen Johann von Rinberg, der sich hier in Oberwesel aufgehalten haben dürfte. Etwas Unvorhergesehenes durchkreuzte den Plan der Ministerialen und zwang sie zur vorzeitigen Anlandung in Bacharach. Von Standesgenossen des Salhofes Lorch gewarnt und an Land gewunken erfuhren sie, daß König Rudolf soeben in Mainz eingetroffen war, der hier die Mainzer Bürgerschaft wegen der vorausgegangenen Judenverfolgung des Jahres 1286 zu einer Geldstrafe verurteilte. Die inszenierte Verfolgungswelle des "Guten Werner" ließ sich indes hierdurch nicht aufhalten,die von den Ministerialen und speziell von Johann von Rinberg auf die Weinbau betreibende Bevölkerung der Rheingegend zugeschnittene Märtyrergeschichte des "Guten Werner" fand ihren Zuspruch. König Adolf nahm Johann von Rinberg als bewährten Feind des Mainzer Erzbischofs 1294 in seinen Dienst als Folge des Zerwürfnisses mit Erzbischof Gerhard. Johann wurde zum königlichen Vogt des Speyergaues ernannt. Zu Beginn des Thronstreites zwischen König Adolf von Nassau und Herzog Albrecht von Österreich und noch vor dem ersten Auftritt Johanns von Rinberg zu Röttingen als Judenverfolger namens Rindfleisch (20.04.) setzte in den Kreisen des königstreuen Adels Schwabens und auch Frankens eine gegen die Juden gerichtete Bewegung ein - von einem "heftigen Geschrei" gegen die dem Erzbischof von Mainz und damit einem der Hauptgegner König Adolfs unterstehenden Juden der Region ist die Rede. Konkretisiert wird das "Geschrei" in einem Fall,einer Standardbeschuldigung: Die Juden hätten den Sohn eines mächtigen Adligen erdrosselt. Die wahren Hintergründe erhellen sich am Verhalten eines dieser Adligen, des Kraft von Hohenlohe, Herrn von Weikersheim und auch Röttingens. Wegen des reichspolitischen Konflikts und der Gegnerschaft des Mainzer Erzbischofs als dem Herrn der Juden wittern sie die Möglichkeit, sich ihrer Schulden bei den Juden durch deren Vernichtung zu entledigen. Aber man ist sich des Risikos politischer Wechselfälle bewußt. - So erlangt der Erzbischof von Mainz nach dem Sieg über König Adolf vom neuen König Albrecht von Habsburg das Privileg, daß ihm die Schuldforderungen der getöteten Juden, welche keine Erben haben, zufallen sollen.- Risikobewußt und zögerlich verhält sich Kraft von Hohenlohe, der zunächst Rücksprache mit dem Bischof von Würzburg hält, um danach gegen die Juden seiner Herrschaft vorgehen zu können und sich so seiner Schulden zu entledigen, was in Weikersheim auch geschah, wohingegen er die Verfolgung in Röttingen Rindfleisch überließ. Der Adel hielt Ausschau nach einem erfolgversprechenden Exekutor, hinter dem man sich verstecken konnte. Man fand ihn in der Person des Speyerer Landvogtes Johann von Rinberg, eines allseits bekannten Feindes des Mainzer Erzbischofs und zugleich eines Judenfeindes, der mit Conrad Rindfleisch einen namentlich ausgewiesenen Judenverfolger zu seinem Stellvertreter ernannt hatte. "Iussu et consensu superiorum" verfolgte Johann von Rinberg die Juden, wie die "Historiae memorabiles" bezeugen, und zwar unter einer jetzt auch beim einfachen Volk, den "arme(n) lude(n)", zugkräftigen Parole: Die Juden hätten dem Heer König Adolfs vergiftetes Rindfleisch geliefert und seien die Verursacher der sich auf Landgebiete ausbreitenden Seuche.- Während der mit dem Schlachtentod König Adolfs in Göllheim endenden Kämpfe um die Krone brach im Heer des Königs eine Seuche aus, die sich auch auf Breisach und weitere Landgebiete ausweitete. Man schrieb dies dem Genuß verdorbenen Rindfleisches zu.Johann von Rinberg machte sich dies zunutze, setzte über den Rhein , begab sich in die königsnahe Landschaft Schwabens und Frankens, um hier gegen die Juden als angeblichen Verursachern der Seuche zu hetzen. Wegen seiner Parole gab man ihm den Namen "Rindfleisch". Begrüßt vom Adel der königsnahen Landschaften und mit Zulauf aus den ärmeren Bevölkerungskreisen zogen seine Scharen die Juden mordend über das Land. Vor Würzburg scheiterte er zunächst allerdings am Widerstand des dortigen Stadtrates. In den Speyergau zurückgekehrt, schloß er sich dem jetzt linksrheinisch operierenden Heer König Adolfs an, kämpfte in der Schlacht bei Göllheim, wurde gefangengenommen, dann aber von dem neuen König Albrecht I. von Habsburg vorzeitig unter Bedingungen entlassen, mit einer Sondermission betraut, die sich inzwischen verselbständigten Judenverfolgungen in Franken kraft seines Einflusses als "capitaneus" und "rex Rintfleisch" auf diese Scharen der Judenverfolger zu beenden. In Würzburg mit seiner Mannschaft angekommen, brach Johann von Rinberg seinen dem König geleisteten Eid, wurde rückfällig, ließ die Juden der Stadt unter Beihilfe einer Bürgeropposition ermorden und startete von hier aus eine neue Verfolgungswelle. Anschließend befreite er mit einem tollkühnen Handstreich den Sohn des getöteten Königs Adolf von Nassau aus der Gefangenschaft Erzbischof Gerhards von Mainz und begab sich daraufhin in Dienst und Schutz des Nassauer Grafenhauses und Erzbischof Dieters von Trier, der ihn zu seinen "Freunden" zählte. Die Identifizierung des berüchtigten Judenverfolgers Rindfleisch des Jahres 1298 setzte bei den Quellen an, die ihn als Edelmann mit Namen de Rinberch nennen. Es konnte geklärt werden, wieso man den Edelmann de Rinberch/Rinberg auch "Rindfleisch" nannte und zwar über Ermittlungen zum Reichslandvogt im Speyergau, Johann von Rinberg und dessen Stellvertreter mit Namen Conrad Rindfleisch angesichts einer sich in der Nachbarschaft und im Operationsgebiet des königlichen Heeres ausbreitenden Seuche, die man auf den Genuß des Rindfleisches zurückführte. Die im Quellenhorizont der Wende des 13. zum 14. Jahrhundert ermittelten Träger dieses Namens wurden überprüft mit dem Ergebnis, daß nur Johann von Rinberg dieser Judenverfolger gewesen sein konnte. Die Hypothese, es könne schließlich noch weitere Rinbergs gegeben haben, die als Täter in Frage kämen, disqualifiziert sich vor diesem Hintergrund als "argumentum ex silentio"! Zu seinem "Täterprofil" paßt sein Motivationshintergrund, sein engeres familiäres und weiteres soziales und politisches Umfeld mit der Anbindung von Judenverfolgungen an die Kämpfe der Ministerialen mit ihrem Landesherrn sowie weitere Ermittlungen - keine Hypothesen sondern Indizien: Vereinbarkeit der Itinerarien Rindfleischs und Johanns von Rinberg / der Name des Stellvertreters Johanns von Rinberg im Speyergau, Conrad Rindfleisch : keine Zufälligkeit sondern Vorbildfunktion / der Vorname des nach Koblenz verzogenen Rindfleisch : Johannes / Rinbergs Mission im Auftrag König Albrechts von Habsburg gegen die Scharen der Judenverfolger und sein Rückfall, seine Konversion : nur Johann von Rinberg kam in Königsnähe hierfür in Frage, zumal sein Name in der Kombination Rint-berg Zeugnis ablegt von der Kenntnis seiner Identität als Rintfleisch (Rintfleisch / Rinberg).
Designing a Randomized Trial with an Age Simulation Suit—Representing People with Health Impairments
(2020)
Due to demographic change, there is an increasing demand for professional care services, whereby this demand cannot be met by available caregivers. To enable adequate care by relieving informal and formal care, the independence of people with chronic diseases has to be preserved for as long as possible. Assistance approaches can be used that support promoting physical activity, which is a main predictor of independence. One challenge is to design and test such approaches without affecting the people in focus. In this paper, we propose a design for a randomized trial to enable the use of an age simulation suit to generate reference data of people with health impairments with young and healthy participants. Therefore, we focus on situations of increased physical activity.
Salivary alpha-amylase (sAA) influences the perception of taste and texture, features both relevant in acquiring food liking and, with time, food preference. However, no studies have yet investigated the relationship between basal activity levels of sAA and food preference. We collected saliva from 57 volunteers (63% women) who we assessed in terms of their preference for different food items. These items were grouped into four categories according to their nutritional properties: high in starch, high in sugar, high glycaemic index, and high glycaemic load. Anthropometric markers of cardiovascular risk were also calculated. Our findings suggest that sAA influences food
preference and body composition in women. Regression analysis showed that basal sAA activity is inversely associated with subjective but not self-reported behavioural preference for foods high in sugar. Additionally, sAA and subjective preference are associated with anthropometric markers of cardiovascular risk. We believe that this pilot study points to this enzyme as an interesting candidate to consider among the physiological factors that modulate eating behaviour.
Dysfunctional eating behavior is a major risk factor for developing all sorts of eating disorders. Food craving is a concept that may help to understand better why and how these and other eating disorders become chronic conditions through non homeastatically-driven mechanisms. As obesity affects people worldwide, cultural differences must be acknowledged to apply proper therapeutic strategies. In this work, we adapted the Food Craving Inventory (FCI) to the German population. We performed a factor analysis of an adaptation of the original FCI in a sample of 326 men and women. We could replicate the factor structure of the FCI on a German population.rnThe factor extraction procedure produced a factor solution that reproduces the fourfactors described in the original inventory, the FCI. Our instrument presents high internal consistency, as well as a significant correlation with measures of convergent and discriminant validity. The FCI-Deutsch (FCI-DE) is a valid instrument to assess craving for particular foods in Germany, and it could, therefore, prove useful in the clinical and research practice in the field of obesity and eating behaviors.
Background: We evaluated depression and social isolation assessed at time of waitlisting as predictors of survival in heart transplant (HTx) recipients. Methods and Results: Between 2005 and 2006, 318 adult HTx candidates were enrolled in the Waiting for a New Heart Study, and 164 received transplantation. Patients were followed until February 2013. Psychosocial characteristics were assessed by questionnaires. Eurotransplant provided medical data at waitlisting, transplantation dates, and donor characteristics; hospitals reported medical data at HTx and date of death after HTx. During a median followâ€up of 70 months (<1"93 months postâ€HTx), 56 (38%) of 148 transplanted patients with complete data died. Depression scores were unrelated to social isolation, and neither correlated with disease severity. Higher depression scores increased the risk of dying (hazard ratio=1.07, 95% confidence interval, 1.01, 1.15, P=0.032), which was moderated by social isolation scores (significant interaction term; hazard ratio = 0.985, 95% confidence interval, 0.973, 0.998; P=0.022). These findings were maintained in multivariate models controlling for covariates (P values 0.020"0.039). Actuarial 1â€year/5â€year survival was best for patients with low depression who were not socially isolated at waitlisting (86% after 1 year, 79% after 5 years). Survival of those who were either depressed, or socially isolated or both, was lower, especially 5 years posttransplant (56%, 60%, and 62%, respectively). Conclusions: Low depression in conjunction with social integration at time of waitlisting is related to enhanced chances for survival after HTx. Both factors should be considered for inclusion in standardized assessments and interventions for HTx candidates. We evaluated depression and social isolation assessed at time of waitlisting as predictors of survival in heart transplant (HTx) recipients.\r\n\r\nMethods and Results: Between 2005 and 2006, 318 adult HTx candidates were enrolled in the Waiting for a New Heart Study, and 164 received transplantation.

Soil degradation due to erosion is a significant worldwide problem at different spatial (from pedon to watershed) and temporal scales. All stages and factors in the erosion process must be detected and evaluated to reduce this environmental issue and protect existing fertile soils and natural ecosystems. Laboratory studies using rainfall simulators allow single factors and interactive effects to be investigated under controlled conditions during extreme rainfall events. In this study, three main factors (rainfall intensity, inclination, and rainfall duration) were assessed to obtain empirical data for modeling water erosion during single rainfall events. Each factor was divided into three levels (− 1, 0, + 1), which were applied in different combinations using a rainfall simulator on beds (6 × 1 m) filled with soil from a study plot located in the arid Sistan region, Iran. The rainfall duration levels tested were 3, 5, and 7 min, the rainfall intensity levels were 30, 60, and 90 mm/h, and the inclination levels were 5, 15, and 25%. The results showed that the highest rainfall intensity tested (90 mm/h) for the longest duration (7 min) caused the highest runoff (62 mm3/s) and soil loss (1580 g/m2/h). Based on the empirical results, a quadratic function was the best mathematical model (R2 = 0.90) for predicting runoff (Q) and soil loss. Single-factor analysis revealed that rainfall intensity was more influential for runoff production than changes in time and inclination, while rainfall duration was the most influential single factor for soil loss. Modeling and three-dimensional depictions of the data revealed that sediment production was high and runoff production lower at the beginning of the experiment, but this trend was reversed over time as the soil became saturated. These results indicate that avoiding the initial stage of erosion is critical, so all soil protection measures should be taken to reduce the impact at this stage. The final stages of erosion appeared too complicated to be modeled, because different factors showed differing effects on erosion.
The Belt and Road Initiative (BRI) has had a significant impact on China in political, economic, and cultural terms. This study focuses on the cultural domain, especially on scholarship students from the countries that signed bilateral cooperation agreements with China under the BRI. Using an integrated approach combining the difference-in-differences method and the gravity model, we explore the correlation between the BRI and the increasing number of international scholarship students funded by the Chinese government, as well as the determinants of students' decision to study in China. The panel data from 2010 to 2018 show that the launch of BRI has had a positive impact on the number of scholarship students from BRI countries. The number of scholarship recipients from non-BRI countries also increased, but at a much slower rate than those from BRI countries. The sole exception is the United States, which has trended downward for both state-funded and self-funded students.

Biographischer Abriss zu Leben und Werk des Schweizer Aufklärers Geord Ludwig Schmid von Auenstein (1720-1806), dessen in französischer Sprache geschriebene Werke (insbesondere seine 'Essais sur divers sujets interessans de politique et de morale' (1760-1763) und seine 'Principes de la Législation Universelle' (1776)) im 18. Jahrhundert ins Deutsche, Englische und Italienische übersetzt wurden.
Objective: Attunement is a novel measure of nonverbal synchrony reflecting the duration of the present moment shared by two interaction partners. This study examined its association with early change in outpatient psychotherapy.
Methods: Automated video analysis based on motion energy analysis (MEA) and cross-correlation of the movement time-series of patient and therapist was conducted to calculate movement synchrony for N = 161 outpatients. Movement-based attunement was defined as the range of connected time lags with significant synchrony. Latent change classes in the HSCL-11 were identified with growth mixture modeling (GMM) and predicted by pre-treatment covariates and attunement using multilevel multinomial regression.
Results: GMM identified four latent classes: high impairment, no change (Class 1); high impairment, early response (Class 2); moderate impairment (Class 3); and low impairment (Class 4). Class 2 showed the strongest attunement, the largest early response, and the best outcome. Stronger attunement was associated with a higher likelihood of membership in Class 2 (b = 0.313, p = .007), Class 3 (b = 0.251, p = .033), and Class 4 (b = 0.275, p = .043) compared to Class 1. For highly impaired patients, the probability of no early change (Class 1) decreased and the probability of early response (Class 2) increased as a function of attunement.
Conclusions: Among patients with high impairment, stronger patient-therapist attunement was associated with early response, which predicted a better treatment outcome. Video-based assessment of attunement might provide new information for therapists not available from self-report questionnaires and support therapists in their clinical decision-making.
Weiße und Nicht-Weiße werden in den visuellen Medien unterschiedlich dargestellt. Unterschiede werden erzeugt durch Narrativik und Technik, insbesondere durch die in Hollywood entwickelte Lichtregie am Set. Weiße stellen üblicherweise die Norm dar. Die US-amerikanische Sitcom SEX AND THE CITY mit ihrem ausschließlich weißen Cast ist ein Beispiel für die Normierung von Whiteness. In der Episode "No Ifs, Ands or Buts" wird die normalerweise unsichtbare Whiteness dem Publikum durch den Auftritt von Afroamerikanern bewusst gemacht. Weiß wird schwarz sowohl ästhetisch, durch die Beleuchtungsdramaturgie, als auch narrativ, durch die Diskussionen über Rassismus, gegenüber gestellt.
Social innovation became a widely discussed topic in politics, research funding programs, and business development. Recent European and US economic and science policies have set aside significant funds to generate and foster social innovation. In view of current challenges such as digitization, Work 4.0, inclusion or migrant integration, the question of how organizations can be empowered to develop new and innovative approaches and service models to social challenges is becoming increasingly urgent. This especially applies to organizations in the fields of education and social services. In education, implementing new ideas and concepts is usually discussed as educational reform, which mostly addresses changes in policy agendas with consequences for national and international education systems. The concept of social innovation however has a different starting point: the source of new ideas and services are identified new, emergent needs in society or re-conceptualized. Such need-based perspectives might bring new impulses to the field of education. Therefore, this paper identifies important existing strands of social innovation research, which need to be considered in the emerging academic discourse on social innovation in education. Looking at social innovation through an education research lens reveals the close relation between learning, creativity, and innovation. Individuals, teams, and even organizations learn, engage in creative problem solving to create new and innovative products and services. From an organizational education perspective, the questions arise, how social innovation emerges and even more important, how the process of developing social innovation can be supported. After a brief introduction in the concept of social innovation, the paper discusses therefore the sites, where social innovation emerges, social innovators, approaches to foster social innovation as well as promoting and hindering factors for social innovation.
Primary focal hyperhidrosis (PFH, OMIM %144110) is a genetically influenced condition characterised by excessive sweating. Prevalence varies between 1.0–6.1% in the general population, dependent on ethnicity. The aetiology of PFH remains unclear but an autosomal dominant mode of inheritance, incomplete penetrance and variable phenotypes have been reported. In our study, nine pedigrees (50 affected, 53 non-affected individuals) were included. Clinical characterisation was performed at the German Hyperhidrosis Centre, Munich, by using physiological and psychological questionnaires. Genome-wide parametric linkage analysis with GeneHunter was performed based on the Illumina genome-wide SNP arrays. Haplotypes were constructed using easyLINKAGE and visualised via HaploPainter. Whole-exome sequencing (WES) with 100x coverage in 31 selected members (24 affected, 7 non-affected) from our pedigrees was achieved by next generation sequencing. We identified four genome-wide significant loci, 1q41-1q42.3, 2p14-2p13.3, 2q21.2-2q23.3 and 15q26.3-15q26.3 for PFH. Three pedigrees map to a shared locus at 2q21.2-2q23.3, with a genome-wide significant LOD score of 3.45. The chromosomal region identified here overlaps with a locus at chromosome 2q22.1-2q31.1 reported previously. Three families support 1q41-1q42.3 (LOD = 3.69), two families share a region identical by descent at 2p14-2p13.3 (LOD = 3.15) and another two families at 15q26.3 (LOD = 3.01). Thus, our results point to considerable genetic heterogeneity. WES did not reveal any causative variants, suggesting that variants or mutations located outside the coding regions might be involved in the molecular pathogenesis of PFH. We suggest a strategy based on whole-genome or targeted next generation sequencing to identify causative genes or variants for PFH.
Background: Hyperhidrosis (excessive sweating, OMIM %114110) is a complex disorder with multifactorial causes. Emotional strains and social stress increase symptoms and lead to a vicious circle. Previously, we showed significantly higher depression scores, and normal cortisol awakening responses in patients with primary focal hyperhidrosis (PFH). Stress reactivity in response to a (virtual) Trier Social Stress Test (TSST-VR) has not been studied so far. Therefore, we measured sweat secretion, salivary cortisol and alpha amylase (sAA) concentrations, and subjective stress ratings in affected and non-affected subjects in response to a TSST-VR.
Method: In this pilot study, we conducted TSST-VRs and performed general linear models with repeated measurements for salivary cortisol and sAA levels, heart rate, axillary sweat and subjective stress ratings for two groups (diagnosed PFH (n = 11), healthy controls (n = 16)).
Results: PFH patients showed significantly heightened sweat secretion over time compared to controls (p = 0.006), with highest quantities during the TSST-VR. In both groups, sweating (p < 0.001), maximum cortisol levels (p = 0.002), feelings of stress (p < 0.001), and heart rate (p < 0.001) but not sAA (p = 0.068) increased significantly in response to the TSST-VR. However, no differences were detected in subjective ratings, cortisol concentrations and heart rate between PFH patients and controls (pall > 0.131).
Conclusion: Patients with diagnosed PFH showed stress-induced higher sweat secretion compared to healthy controls but did not differ in the stress reactivity with regard to endocrine or subjective markers. This pilot study is in need of replication to elucidate the role of the sympathetic nervous system as a potential pathway involved in the stress-induced emotional sweating of PFH patients.
Kartenschätze aus Italien
(2018)
Die Entdeckungen der Neuzeit sowie verbesserte Druckverfahren führten ab dem 16. Jahrhundert zu einem enormen Aufschwung der Kartographie. Gerade in Italien entstanden blühende kartographische Zentren mit exzellentem Ruf, die innerhalb kurzer Zeit große Fortschritte hinsichtlich Genauigkeit und Übersichtlichkeit machten. Aus dem der Universitätsbibliothek Trier vermachten Nachlass des Kartensammlers Fritz Hellwig werden drei repräsentative Beispiele vorgestellt.
Dry tropical forests undergo massive conversion and degradation processes. This also holds true for the extensive Miombo forests that cover large parts of Southern Africa. While the largest proportional area can be found in Angola, the country still struggles with food shortages, insufficient medical and educational supplies, as well as the ongoing reconstruction of infrastructure after 27 years of civil war. Especially in rural areas, the local population is therefore still heavily dependent on the consumption of natural resources, as well as subsistence agriculture. This leads, on one hand, to large areas of Miombo forests being converted for cultivation purposes, but on the other hand, to degradation processes due to the selective use of forest resources. While forest conversion in south-central rural Angola has already been quantitatively described, information about forest degradation is not yet available. This is due to the history of conflicts and the therewith connected research difficulties, as well as the remote location of this area. We apply an annual time series approach using Landsat data in south-central Angola not only to assess the current degradation status of the Miombo forests, but also to derive past developments reaching back to times of armed conflicts. We use the Disturbance Index based on tasseled cap transformation to exclude external influences like inter-annual variation of rainfall. Based on this time series, linear regression is calculated for forest areas unaffected by conversion, but also for the pre-conversion period of those areas that were used for cultivation purposes during the observation time. Metrics derived from linear regression are used to classify the study area according to their dominant modification processes.rnWe compare our results to MODIS latent integral trends and to further products to derive information on underlying drivers. Around 13% of the Miombo forests are affected by degradation processes, especially along streets, in villages, and close to existing agriculture. However, areas in presumably remote and dense forest areas are also affected to a significant extent. A comparison with MODIS derived fire ignition data shows that they are most likely affected by recurring fires and less by selective timber extraction. We confirm that areas that are used for agriculture are more heavily disturbed by selective use beforehand than those that remain unaffected by conversion. The results can be substantiated by the MODIS latent integral trends and we also show that due to extent and location, the assessment of forest conversion is most likely not sufficient to provide good estimates for the loss of natural resources.
Academic self-concept (ASC) is comprised of individual perceptions of one- own academic ability. In a cross-sectional quasi-representative sample of 3,779 German elementary school children in grades 1 to 4, we investigated (a) the structure of ASC, (b) ASC profile formation, an aspect of differentiation that is reflected in lower correlations between domain-specific ASCs with increasing grade level, (c) the impact of (internal) dimensional comparisons of one- own ability in different school subjects for profile formation of ASC, and (d) the role played by differences in school grades between subjects for these dimensional comparisons. The nested Marsh/Shavelson model, with general ASC at the apex and math, writing, and reading ASC as specific factors nested under general ASC fitted the data at all grade levels. A first-order factor model with math, writing, reading, and general ASCs as correlated factors provided a good fit, too. ASC profile formation became apparent during the first two to three years of school. Dimensional comparisons across subjects contributed to ASC profile formation. School grades enhanced these comparisons, especially when achievement profiles were uneven. In part, findings depended on the assumed structural model of ASCs. Implications for further research are discussed with special regard to factors influencing and moderating dimensional comparisons.
It is generally assumed that the temperature increase associated with global climate change will lead to increased thunderstorm intensity and associated heavy precipitation events. In the present study it is investigated whether the frequency of thunderstorm occurrences will in- or decrease and how the spatial distribution will change for the A1B scenario. The region of interest is Central Europe with a special focus on the Saar-Lor-Lux region (Saarland, Lorraine, Luxembourg) and Rhineland-Palatinate.Daily model data of the COSMO-CLM with a horizontal resolution of 4.5 km is used. The simulations were carried out for two different time slices: 1971"2000 (C20), and 2071"2100 (A1B). Thunderstorm indices are applied to detect thunderstorm-prone conditions and differences in their frequency of occurrence in the two thirty years timespans. The indices used are CAPE (Convective Available Potential Energy), SLI (Surface Lifted Index), and TSP (Thunderstorm Severity Potential).The investigation of the present and future thunderstorm conducive conditions show a significant increase of non-thunderstorm conditions. The regional averaged thunderstorm frequencies will decrease in general, but only in the Alps a potential increase in thunderstorm occurrences and intensity is found. The comparison between time slices of 10 and 30 years length show that the number of gridpoints with significant signals increases only slightly. In order to get a robust signal for severe thunderstorm, an extension to more than 75 years would be necessary.
The larval stage of the European fire salamander (Salamandra salamandra) inhabits both lentic and lotic habitats. In the latter, they are constantly exposed to unidirectional water flow, which has been shown to cause downstream drift in a variety of taxa. In this study, a closed artificial creek, which allowed us to keep the water flow constant over time and, at the same time, to simulates with predefined water quantities and durations, was used to examine the individual movement patterns of marked larval fire salamanders exposed to unidirectional flow. Movements were tracked by marking the larvae with VIAlpha tags individually and by using downstream and upstream traps. Most individuals showed stationarity, while downstream drift dominated the overall movement pattern. Upstream movements were rare and occurred only on small distances of about 30 cm; downstream drift distances exceeded 10 m (until next downstream trap). The simulated flood events increased drift rates significantly, even several days after the flood simulation experiments. Drift probability increased with decreasing body size and decreasing nutritional status. Our results support the production hypothesis as an explanation for the movements of European fire salamander larvae within creeks.
Production of biomass feedstock for methanation in Europe has focused on silages of maize and cereals. As ecological awareness has increased in the last several years, more attention is being focused on perennial energy crops (PECs). Studies of specific PECs have shown that their cultivation may enhance agrobiodiversity and increase soil organic carbon stocks while simultaneously providing valuable feedstock for methanation. This study was designed to compare soil quality indicators under annual energy crops (AECs), PECs and permanent grassland (PGL) on the landscape level in south-western Germany. At a total 25 study sites, covering a wide range of parent materials, the cropping systems were found adjacent to each other. Stands were commercially managed, and PECs included different species such as the Cup Plant, Tall Wheatgrass, Giant Knotweed, Miscanthus, Virginia Mallow and Reed Canary Grass. Soil sampling was carried out for the upper 20 cm of soil. Several soil quality indicators, including soil organic carbon (Corg), soil microbial biomass (Cmic), and aggregate stability, showed that PECs were intermediate between AEC and PGL systems. At landscape level, mean Corg content for (on average) 6.1-year-old stands of PEC was 22.37 (±7.53) g kg1, compared to 19.23 (±8.08) and 32.08 (±10.11) for AEC and PGL. Cmic contents were higher in PECs (356 ± 241 lgCg1) compared to AECs (291 ± 145) but significantly lower than under PGL (753 ± 417). The aggregate stability increased by almost 65% in PECs compared to AEC but was still 57% lower than in PGL. Indicator differences among cropping systems were more pronounced when inherent differences in the parent material were accounted for in the comparisons. Overall, these results suggest that the cultivation of PECs has positive effects on soil quality indicators. Thus, PECs may offer potential to make the production of biomass feedstock more sustainable.
Energy transition strategies in Germany have led to an expansion of energy crop cultivation in landscape, with silage maize as most valuable feedstock. The changes in the traditional cropping systems, with increasing shares of maize, raised concerns about the sustainability of agricultural feedstock production regarding threats to soil health. However, spatially explicit data about silage maize cultivation are missing; thus, implications for soil cannot be estimated in a precise way. With this study, we firstly aimed to track the fields cultivated with maize based on remote sensing data. Secondly, available soil data were target-specifically processed to determine the site-specific vulnerability of the soils for erosion and compaction. The generated, spatially-explicit data served as basis for a differentiated analysis of the development of the agricultural biogas sector, associated maize cultivation and its implications for soil health. In the study area, located in a low mountain range region in Western Germany, the number and capacity of biogas producing units increased by 25 installations and 10,163 kW from 2009 to 2016. The remote sensing-based classification approach showed that the maize cultivation area was expanded by 16% from 7305 to 8447 hectares. Thus, maize cultivation accounted for about 20% of the arable land use; however, with distinct local differences. Significant shares of about 30% of the maize cultivation was done on fields that show at least high potentials for soil erosion exceeding 25 t soil ha−1 a−1. Furthermore, about 10% of the maize cultivation was done on fields that pedogenetically show an elevated risk for soil compaction. In order to reach more sustainable cultivation systems of feedstock for anaerobic digestion, changes in cultivated crops and management strategies are urgently required, particularly against first signs of climate change. The presented approach can regionally be modified in order to develop site-adapted, sustainable bioenergy cropping systems.
Harvesting of silage maize in late autumn on waterlogged soils may result in several ecological problems such as soil compaction and may subsequently be a major threat to soil fertility in Europe. It was hypothesized that perennial energy crops might reduce the vulnerability for soil compaction through earlier harvest dates and improved soil stability. However, the performance of such crops to be grown on soil that are periodically waterlogged and implications for soil chemical and microbial properties are currently an open issue. Within the framework of a two-year pot experiment we investigated the potential of the cup plant (Silphium perfoliatum L.), Jerusalem artichoke (Helianthus tuberosus), giant knotweed (Fallopia japonicum X bohemica), tall wheatgrass (Agropyron elongatum), and reed canary grass (Phalaris arundinacea) for cultivation under periodically waterlogged soil conditions during the winter half year and implications for soil chemical and biological properties. Examined perennial energy crops coped with periodical waterlogging and showed yields 50% to 150% higher than in the control which was never faced with waterlogging. Root formation was similar in waterlogged and non-waterlogged soil layers. Soil chemical and microbial properties clearly responded to different soil moisture treatments. For example, dehydrogenase activity was two to four times higher in the periodically waterlogged treatment compared to the control. Despite waterlogging, aerobic microbial activity was significantly elevated indicating morphological and metabolic adaptation of the perennial crops to withstand waterlogged conditions. Thus, our results reveal first evidence of a site-adapted biomass production on periodical waterlogged soils through the cultivation of perennial energy crops and for intense plant microbe interactions.
FAMILIE LEDEBOER: TERUGKEER NAAR NEDERLAND (1926) ist einer der wenigen noch heute erhaltenen Familienfilme aus der niederländischen Kolonie Nederlands-Indië, dem heutigen Indonesien. Der Dokumentarfilmer Willy Mullens zeigt hier das Verhältnis der niederländischen Kolonialherren und ihren kolonisierten Anderen in einer sehr persönlichen, wenngleich auch nicht alltäglichen Form. Anlässlich der Rückkehr der Familie in die Niederlande werden ausgewählte Begegnungen zwischen der Familie Ledeboer und ihren Angestellten dargestellt, in denen der abstrakte, kolonial-ideologische Gegensatz zwischen dem "Selbst" und dem "Anderen" konkrete Form annimmt. Obgleich der Film den Daheimgebliebenen zeigen sollte, wie man in der Kolonie lebt und wie es einem in der Fremde ergeht, sollte zugleich durch Bilder von Ordnung und Stabilität und die Betonung der Loyalität der Angestellten und der guten Fürsorge über diese die Kolonialideologie einer weißen Überlegenheit gestützt werden. Dies gewinnt insbesondere vor dem Hintergrund zunehmender Konflikte und eines aufkeimenden Nationalismus in der Kolonie und einer damit einhergehenden Infragestellung der kolonialen Ordnung zu dieser Zeit an Bedeutung. Der Familienfilm diente so zur Konstruktion von Normalität und zur Bestätigung der eigenen Identität als Familie und als Europäer in der Fremde, zur Bestätigung von Status und Zugehörigkeit und zur Vergewisserung des eigenen Selbstbildes auf der individuellen wie auch kollektiven Ebene. Dennoch bleibt die Darstellung des Verhältnisses von Kolonialherren und Kolonisierten ambivalent. Obschon versucht wird, bei aller Fürsorglichkeit auch soziale Distanz und Überlegenheit zu transportieren, merkt man dem Umgang auch die Vertrautheit der tagtäglichen Nähe und Interaktion an.
Natural hazards are diverse and uneven in time and space, therefore, understanding its complexity is key to save human lives and conserve natural ecosystems. Reducing the outputs obtained after each modelling analysis is key to present the results for stakeholders, land managers and policymakers. So, the main goal of this survey was to present a method to synthesize three natural hazards in one multi-hazard map and its evaluation for hazard management and land use planning. To test this methodology, we took as study area the Gorganrood Watershed, located in the Golestan Province (Iran). First, an inventory map of three different types of hazards including flood, landslides, and gullies was prepared using field surveys and different official reports. To generate the susceptibility maps, a total of 17 geo-environmental factors were selected as predictors using the MaxEnt (Maximum Entropy) machine learning technique. The accuracy of the predictive models was evaluated by drawing receiver operating characteristic-ROC curves and calculating the area under the ROC curve-AUCROC. The MaxEnt model not only implemented superbly in the degree of fitting, but also obtained significant results in predictive performance. Variables importance of the three studied types of hazards showed that river density, distance from streams, and elevation were the most important factors for flood, respectively. Lithological units, elevation, and annual mean rainfall were relevant for detecting landslides. On the other hand, annual mean rainfall, elevation, and lithological units were used for gully erosion mapping in this study area. Finally, by combining the flood, landslides, and gully erosion susceptibility maps, an integrated multi-hazard map was created. The results demonstrated that 60% of the area is subjected to hazards, reaching a proportion of landslides up to 21.2% in the whole territory. We conclude that using this type of multi-hazard map may be a useful tool for local administrators to identify areas susceptible to hazards at large scales as we demonstrated in this research.
Der vorliegende Beitrag greift die öffentliche Diskussion um den rechtspolitischen Umgang mit Hass, Hetze und Antisemitismus auf, die insbesondere nach dem Terroranschlag der Hamas am 07.10.2023 an Intensität und Dringlichkeit zugenommen hat. Dabei beleuchtet er einerseits das Straf- und Zivilrecht, legt andererseits einen besonderen Fokus auf öffentlich-rechtliche Konstellationen. Auf jedem dieser Gebiete werden Schwächen und Potenziale des Rechts und der Rechtsprechung aufgezeigt, zugleich aber auch die Grenzen staatlicher Gewalt verdeutlicht. Denn letztlich handelt es sich um ein gesellschaftliches Problem, dem – trotz aller Notwendigkeit staatlichen Handelns – in erster Linie durch Information, und erst in zweiter Linie durch das Recht begegnet werden muss.
The outbreak of the COVID-19 pandemic has also led to many conspiracy theories. While the origin of the pandemic in China led some, including former US president Donald Trump, to dub the pathogen “Chinese virus” and to support anti-Chinese conspiracy narratives, it caused Chinese state officials to openly support anti-US conspiracy theories about the “true” origin of the virus. In this article, we study whether nationalism, or more precisely uncritical patriotism, is related to belief in conspiracy theories among normal people. We hypothesize based on group identity theory and motivated reasoning that for the particular case of conspiracy theories related to the origin of COVID-19, such a relation should be stronger for Chinese than for Germans. To test this hypothesis, we use survey data from Germany and China, including data from the Chinese community in Germany. We also look at relations to other factors, in particular media consumption and xenophobia.
The presence of sea ice leads in the sea ice cover represents a key feature in polar regions by controlling the heat exchange between the relatively warm ocean and cold atmosphere due to increased fluxes of turbulent sensible and latent heat. Sea ice leads contribute to the sea ice production and are sources for the formation of dense water which affects the ocean circulation. Atmospheric and ocean models strongly rely on observational data to describe the respective state of the sea ice since numerical models are not able to produce sea ice leads explicitly. For the Arctic, some lead datasets are available, but for the Antarctic, no such data yet exist. Our study presents a new algorithm with which leads are automatically identified in satellite thermal infrared images. A variety of lead metrics is used to distinguish between true leads and detection artefacts with the use of fuzzy logic. We evaluate the outputs and provide pixel-wise uncertainties. Our data yield daily sea ice lead maps at a resolution of 1 km2 for the winter months November– April 2002/03–2018/19 (Arctic) and April–September 2003–2019 (Antarctic), respectively. The long-term average of the lead frequency distributions show distinct features related to bathymetric structures in both hemispheres.
A model-based temperature adjustment scheme for wintertime sea-ice production retrievals from MODIS
(2022)
Knowledge of the wintertime sea-ice production in Arctic polynyas is an important requirement for estimations of the dense water formation, which drives vertical mixing in the upper ocean. Satellite-based techniques incorporating relatively high resolution thermal-infrared data from MODIS in combination with atmospheric reanalysis data have proven to be a strong tool to monitor large and regularly forming polynyas and to resolve narrow thin-ice areas (i.e., leads) along the shelf-breaks and across the entire Arctic Ocean. However, the selection of the atmospheric data sets has a large influence on derived polynya characteristics due to their impact on the calculation of the heat loss to the atmosphere, which is determined by the local thin-ice thickness. In order to overcome this methodical ambiguity, we present a MODIS-assisted temperature adjustment (MATA) algorithm that yields corrections of the 2 m air temperature and hence decreases differences between the atmospheric input data sets. The adjustment algorithm is based on atmospheric model simulations. We focus on the Laptev Sea region for detailed case studies on the developed algorithm and present time series of polynya characteristics in the winter season 2019/2020. It shows that the application of the empirically derived correction decreases the difference between different utilized atmospheric products significantly from 49% to 23%. Additional filter strategies are applied that aim at increasing the capability to include leads in the quasi-daily and persistence-filtered thin-ice thickness composites. More generally, the winter of 2019/2020 features high polynya activity in the eastern Arctic and less activity in the Canadian Arctic Archipelago, presumably as a result of the particularly strong polar vortex in early 2020.
Repeatedly encountering a stimulus biases the observer’s affective response and evaluation of the stimuli. Here we provide evidence for a causal link between mere exposure to fictitious news reports and subsequent voting behavior. In four pre-registered online experiments, participants browsed through newspaper webpages and were tacitly exposed to names of fictitious politicians. Exposure predicted voting behavior in a subsequent mock election, with a consistent preference for frequent over infrequent names, except when news items were decidedly negative. Follow-up analyses indicated that mere media presence fuels implicit personality theories regarding a candidate’s vigor in political contexts. News outlets should therefore be mindful to cover political candidates as evenly as possible.
Ability self-concept (SC) and self-efficacy (SE) are central competence-related self-perceptions that affect students’ success in educational settings. Both constructs show conceptual differences but their empirical differentiation in higher education has not been sufficiently demonstrated. In the present study, we investigated the empirical differentiation of SC and SE in higher education with N = 1,243 German psychology students (81% female; age M = 23.62 years), taking into account central methodological requirements that, in part, have been neglected in prior studies. SC and SE were assessed at the same level of specificity, only cognitive SC items were used, and multiple academic domains were considered. We modeled the structure of SC and SE taking into account a multidimensional and/or hierarchical structure and investigated the empirical differentiation of both constructs on different levels of generality (i.e., domain-specific and domain-general). Results supported the empirical differentiation of SC and SE with medium-sized positive latent correlations (range r = .57 - .68) between SC and SE on different levels of generality. The knowledge about the internal structure of students’ SC and SE and the differentiation of both constructs can help us to develop construct-specific and domain-specific intervention strategies. Future empirical comparisons of the predictive power of SC and SE can provide further evidence that both represent empirical different constructs.
The forward testing effect is an indirect benefit of retrieval practice. It refers to the finding that retrieval practice of previously studied information enhances learning and retention of subsequently studied other information in episodic memory tasks. Here, two experiments were conducted that investigated whether retrieval practice influences participants’ performance in other tasks, i.e., arithmetic tasks. Participants studied three lists of words in anticipation of a final recall test. In the testing condition, participants were immediately tested on lists 1 and 2 after study of each list, whereas in the restudy condition, they restudied lists 1 and 2 after initial study. Before and after study of list 3, participants did an arithmetic task. Finally, participants were tested on list 3, list 2, and list 1. Different arithmetic tasks were used in the two experiments. Participants did a modular arithmetic task in Experiment 1a and a single-digit multiplication task in Experiment 1b. The results of both experiments showed a forward testing effect with interim testing of lists 1 and 2 enhancing list 3 recall in the list 3 recall test, but no effects of recall testing of lists 1 and 2 for participants’ performance in the arithmetic tasks. The findings are discussed with respect to cognitive load theory and current theories of the forward testing effect.
Long-Term Memory Updating: The Reset-of-Encoding Hypothesis in List-Method Directed Forgetting
(2017)
People- memory for new information can be enhanced by cuing them to forget older information, as is shown in list-method directed forgetting (LMDF). In this task, people are cued to forget a previously studied list of items (list 1) and to learn a new list of items (list 2) instead. Such cuing typically enhances memory for the list 2 items and reduces memory for the list 1 items, which reflects effective long-term memory updating. This review focuses on the reset-of-encoding (ROE) hypothesis as a theoretical explanation of the list 2 enhancement effect in LMDF. The ROE hypothesis is based on the finding that encoding efficacy typically decreases with number of encoded items and assumes that providing a forget cue after study of some items (e.g., list 1) resets the encoding process and makes encoding of subsequent items (e.g., early list 2 items) as effective as encoding of previously studied (e.g., early list 1) items. The review provides an overview of current evidence for the ROE hypothesis. The evidence arose from recent behavioral, neuroscientific, and modeling studies that examined LMDF on both an item and a list level basis. The findings support the view that ROE plays a critical role for the list 2 enhancement effect in LMDF. Alternative explanations of the effect and the generalizability of ROE to other experimental tasks are discussed.
List-method directed forgetting (LMDF) is the demonstration that people can intentionally forget previously studied information when they are asked to forget what they have previously learned and remember new information instead. In addition, recent research demonstrated that people can selectively forget when cued to forget only a subset of the previously studied information. Both forms of forgetting are typically observed in recall tests, in which the to-be-forgotten and to-be-remembered information is tested independent of original cuing. Thereby, both LMDF and selective directed forgetting (SDF) have been studied mostly with unrelated item materials (e.g., word lists). The present study examined whether LMDF and SDF generalize to prose material. Participants learned three prose passages, which they were cued to remember or forget after the study of each passage. At the time of testing, participants were asked to recall the three prose passages regardless of original cuing. The results showed no significant differences in recall of the three lists as a function of cuing condition. The findings suggest that LMDF and SDF do not occur with prose material. Future research is needed to replicate and extend these findings with (other) complex and meaningful materials before drawing firm conclusions. If the null effect proves to be robust, this would have implications regarding the ecological validity and generalizability of current LMDF and SDF findings.
The forward testing effect refers to the finding that retrieval practice of previously studied information enhances learning and retention of subsequently studied other information. While most of the previous research on the forward testing effect examined group differences, the present study took an individual differences approach to investigate this effect. Experiment 1 examined whether the forward effect has test-retest reliability between two experimental sessions. Experiment 2 investigated whether the effect is related to participants’ working memory capacity. In both experiments (and each session of Experiment 1), participants studied three lists of items in anticipation of a final cumulative recall test. In the testing condition, participants were tested immediately on lists 1 and 2, whereas in the restudy condition, they restudied lists 1 and 2. In both conditions, participants were tested immediately on list 3. On the group level, the results of both experiments demonstrated a forward testing effect, with interim testing of lists 1 and 2 enhancing immediate recall of list 3. On the individual level, the results of Experiment 1 showed that the forward effect on list 3 recall has moderate test-retest reliability between two experimental sessions. In addition, the results of Experiment 2 showed that the forward effect on list 3 recall does not depend on participants’ working memory capacity. These findings suggest that the forward testing effect is reliable at the individual level and affects learners at a wide range of working memory capacities alike. The theoretical and practical implications of the findings are discussed.
The forward effect of testing refers to the finding that retrieval practice of previously studied information increases retention of subsequently studied other information. It has recently been hypothesized that the forward effect (partly) reflects the result of a reset-of-encoding (ROE) process. The proposal is that encoding efficacy decreases with an increase in study material, but testing of previously studied information resets the encoding process and makes the encoding of the subsequently studied information as effective as the encoding of the previously studied information. The goal of the present study was to verify the ROE hypothesis on an item level basis. An experiment is reported that examined the effects of testing in comparison to restudy on items’ serial position curves. Participants studied three lists of items in each condition. In the testing condition, participants were tested immediately on non-target lists 1 and 2, whereas in the restudy condition, they restudied lists 1 and 2. In both conditions, participants were tested immediately on target list 3. Influences of condition and items’ serial learning position on list 3 recall were analyzed. The results showed the forward effect of testing and furthermore that this effect varies with items’ serial list position. Early target list items at list primacy positions showed a larger enhancement effect than middle and late target list items at non-primacy positions. The results are consistent with the ROE hypothesis on an item level basis. The generalizability of the ROE hypothesis across different experimental tasks, like the list-method directed-forgetting task, is discussed.
Soil organic matter (SOM) is an indispensable component of terrestrial ecosystems. Soil organic carbon (SOC) dynamics are influenced by a number of well-known abiotic factors such as clay content, soil pH, or pedogenic oxides. These parameters interact with each other and vary in their influence on SOC depending on local conditions. To investigate the latter, the dependence of SOC accumulation on parameters and parameter combinations was statistically assessed that vary on a local scale depending on parent material, soil texture class, and land use. To this end, topsoils were sampled from arable and grassland sites in south-western Germany in four regions with different soil parent material. Principal component analysis (PCA) revealed a distinct clustering of data according to parent material and soil texture that varied largely between the local sampling regions, while land use explained PCA results only to a small extent. The PCA clusters were differentiated into total clusters that contain the entire dataset or major proportions of it and local clusters representing only a smaller part of the dataset. All clusters were analysed for the relationships between SOC concentrations (SOC %) and mineral-phase parameters in order to assess specific parameter combinations explaining SOC and its labile fractions hot water-extractable C (HWEC) and microbial biomass C (MBC). Analyses were focused on soil parameters that are known as possible predictors for the occurrence and stabilization of SOC (e.g. fine silt plus clay and pedogenic oxides). Regarding the total clusters, we found significant relationships, by bivariate models, between SOC, its labile fractions HWEC and MBC, and the applied predictors. However, partly low explained variances indicated the limited suitability of bivariate models. Hence, mixed-effect models were used to identify specific parameter combinations that significantly explain SOC and its labile fractions of the different clusters. Comparing measured and mixed-effect-model-predicted SOC values revealed acceptable to very good regression coefficients (R2=0.41–0.91) and low to acceptable root mean square error (RMSE = 0.20 %–0.42 %). Thereby, the predictors and predictor combinations clearly differed between models obtained for the whole dataset and the different cluster groups. At a local scale, site-specific combinations of parameters explained the variability of organic carbon notably better, while the application of total models to local clusters resulted in less explained variance and a higher RMSE. Independently of that, the explained variance by marginal fixed effects decreased in the order SOC > HWEC > MBC, showing that labile fractions depend less on soil properties but presumably more on processes such as organic carbon input and turnover in soil.
Auf Twitter sind viele Journalisten mit persönlichen Accounts präsent und damit ein potenzieller Interaktionspartner für das Publikum. Untersuchungen aktiver Twitterer zeigen, dass auf der Netzwerkplattform politisch interessierte, persönlichkeitsstarke Nutzer interagieren, die sich vom Durchschnitt typischer Internetnutzer unterscheiden. Nachrichtenjournalisten berichten über negative Erfahrungen im direkten Publikumskontakt auf Twitter. Anders als bei Nutzerkommentaren auf Nachrichtenseiten sind öffentliche Anschriebe und Kontakte zu Journalisten auch unabhängig von einem Beitrag möglich. Zu diesem Phänomen existieren bislang jedoch kaum Studien. Über ein Tracking der Anschriebe wird daher erstens untersucht, wie häufig Politikjournalisten 2017 überhaupt in Tweets erwähnt wurden. Zweitens wurden die Nutzer befragt, die die Journalisten angeschrieben haben. Eine Nutzergruppe aus mehreren zehntausend Accounts nimmt Adressierungen vor. Die Erwähnungen verteilen sich unter den Journalisten ungleich. Die Nutzung von Blogs als alternative Informationsquelle und starke politische Orientierungen erklären das Vorkommen häufiger Interaktionen. Als Hauptmotivationen für Interaktionen zeigen sich das Bedürfnis nach eigener Meinungsäußerung und Kritik sowie das Weitergeben von neuen Informationen und Feedback an Journalisten. Sind diese Motivationen ausgeprägt, tendieren die Nutzer eher zu häufigen Interaktionen.
COVID-19 was a harsh reminder that diseases are an aspect of human existence and mortality. It was also a live experiment in the formation and alteration of disease-related attitudes. Not only are these attitudes relevant to an individual’s self-protective behavior, but they also seem to be associated with social and political attitudes more broadly. One of these attitudes is Social Darwinism, which holds that a pandemic benefits society by enabling nature “to weed out the weak”. In two countries (N = 300, N = 533), we introduce and provide evidence for the reliability, validity, and usefulness of the Disease-Related Social Darwinism (DRSD) Short Scale measuring this concept. Results indicate that DRSD is meaningful related to other central political attitudes like Social Dominance Orientation, Authoritarianism and neoliberalism. Importantly, the scale significantly predicted people’s protective behavior during the Pandemic over and above general social Darwinism. Moreover, it significantly predicted conservative attitudes, even after controlling for Social Dominance Orientation.
This study scrutinizes press photographs published during the first 6 weeks of the Russian War in Ukraine, beginning February 24th, 2022. Its objective is to shed light on the emotions evoked in Internet-savvy audiences. This empirical research aims to contribute to the understanding of emotional media effects that shape attitudes and actions of ordinary citizens. Main research questions are: What kind of empathic reactions are observed during the Q-sort study? Which visual patterns are relevant for which emotional evaluations and attributions? The assumption is that the evaluations and attributions of empathy are not random, but follow specific patterns. The empathic reactions are based on visual patterns which, in turn, influence the type of empathic reaction. The identification of specific categories for visual and emotional reaction patterns are arrived at in different methodological processes. Visual pattern categories were developed inductively, using the art history method of iconography-iconology to identify six distinct types of visual motifs in a final sample of 33 war photographs. The overarching categories for empathic reactions—empty empathy, vicarious traumatization and witnessing—were applied deductively, building on E. Ann Kaplan's pivotal distinctions. The main result of this research are three novel categories that combine visual patterns with empathic reaction patterns. The labels for these categories are a direct result of the Q-factorial analysis, interpreted through the lense of iconography-iconology. An exploratory nine-scale forced-choice Q-sort study (Nstimuli = 33) was implemented, followed by self-report interviews with a total of 25 participants [F = 16 (64%), M = 9 (36%), Mage = 26.4 years]. Results from this exploratory research include motivational statements on the meanings of war photography from semi-structured post-sort-interviews. The major result of this study are three types of visual patterns (“factors”) that govern distinct empathic reactions in participants: Factor 1 is “veiled empathy” with highest empathy being attributed to photos showing victims whose corpses or faces were veiled. Additional features of “veiled empathy” are a strong anti-politician bias and a heightened awareness of potential visual manipulation. Factor 2 is “mirrored empathy” with highest empathy attributions to photos displaying human suffering openly. Factor 3 focused on the context. It showed a proclivity for documentary style photography. This pattern ranked photos without clear contextualization lower in empathy than those photos displaying the fully contextualized setting. To the best of our knowledge, no study has tested empathic reactions to war photography empirically. In this respect, the study is novel, but also exploratory. Findings like the three patterns of visual empathy might be helpful for photo selection processes in journalism, for political decision-making, for the promotion of relief efforts, and for coping strategies in civil society to deal with the potentially numbing or traumatizing visual legacy of the War in Ukraine.

Studienförderung in der Frühen Neuzeit. Das Luzerner Stipendienwesen in den Jahren 1550 bis 1650
(2008)
Anhand von Ratsprotokolle, Korrespondenzen und Testamenten wurde das Luzerner Stipendienwesen hinsichtlich seiner Funktionsweise, Intension und Wirkung untersucht für den Zeitraum 1550 bis 1650.Es stellt sich heraus, dass die Stipendien als obrigkeitliches Instrument der politischen und konfessionellen Stabilisierung des Standes Luzern dienten. Dabei erhielten in erster Linie die Söhne der Ratsherrengeschlechter die Studienförderung. D.h., dass eine Bildungsförderung eher armer Gesellschaftsschichten dem Anliegen der Statussicherung der neuen Luzerner Ratsgeschlechter entgegen stand. Dennoch wurden die obrigkeitlichen Stipendien nicht effektiv genutzt, wobei sie in Verbindung mit den (kirchlich-)privaten Studienstiftungen ein aufeinander aufbauendes Stipendiensystem ausbildeten, das die Grundausbildung und die Hochschulbildung zu mindest für einige Stipendiaten ermöglichte.
The process of land degradation needs to be understood at various spatial and temporal scales in order to protect ecosystem services and communities directly dependent on it. This is especially true for regions in sub-Saharan Africa, where socio economic and political factors exacerbate ecological degradation. This study identifies spatially explicit land change dynamics in the Copperbelt province of Zambia in a local context using satellite vegetation index time series derived from the MODIS sensor. Three sets of parameters, namely, monthly series, annual peaking magnitude, and annual mean growing season were developed for the period 2000 to 2019. Trend was estimated by applying harmonic regression on monthly series and linear least square regression on annually aggregated series. Estimated spatial trends were further used as a basis to map endemic land change processes. Our observations were as follows: (a) 15% of the study area dominant in the east showed positive trends, (b) 3% of the study area dominant in the west showed negative trends, (c) natural regeneration in mosaic landscapes (post shifting cultivation) and land management in forest reserves were chiefly responsible for positive trends, and (d) degradation over intact miombo woodland and cultivation areas contributed to negative trends. Additionally, lower productivity over areas with semi-permanent agriculture and shift of new encroachment into woodlands from east to west of Copperbelt was observed. Pivot agriculture was not a main driver in land change. Although overall greening trends prevailed across the study site, the risk of intact woodlands being exposed to various disturbances remains high. The outcome of this study can provide insights about natural and assisted landscape restoration specifically addressing the miombo ecoregion.
Despite significant advances in terms of the adoption of formal Intellectual Property Rights (IPR) protection, enforcement of and compliance with IPR regulations remains a contested issue in one of the world's major contemporary economies—China. The present review seeks to offer insights into possible reasons for this discrepancy as well as possible paths of future development by reviewing prior literature on IPR in China. Specifically, it focuses on the public's perspective, which is a crucial determinant of the effectiveness of any IPR regime. It uncovers possible differences with public perspectives in other countries and points to mechanisms (e.g., political, economic, cultural, and institutional) that may foster transitions over time in both formal IPR regulation and in the public perception of and compliance with IPR in China. On this basis, the review advances suggestions for future research in order to improve scholars' understanding of the public's perspective of IPR in China, its antecedents and implications.
Der Aufsatz beschreibt zunächst die politische Publizistik der Mainzer Jakobiner und sodann die publizistische Reaktion der gegenrevolutionären Kräfte. Die abschließenden Überlegungen kreisen um die Findung von politischem Konsens als Zielvorstellung im Wirken der Mainzer Jakobiner und versuchen, der noch immer verbreiteten Auffassung von einem autoritären Demokratieverständnis der Mainzer Jakobiner entgegenzutreten.
We study planned changes in protective routines after the COVID-19 pandemic: in a survey in Germany among >650 respondents, we find that the majority plans to use face masks in certain situations even after the end of the pandemic. We observe that this willingness is strongly related to the perception that there is something to be learned from East Asians’ handling of pandemics, even when controlling for perceived protection by wearing masks. Given strong empirical evidence that face masks help prevent the spread of respiratory diseases and given the considerable estimated health and economic costs of such diseases even pre-Corona, this would be a very positive side effect of the current crisis.
Measurements of dust emissions and the modeling of dissipation dynamics and total values are related to great uncertainties. Agricultural activity, especially soil cultivation, may be an essential component to calculate and model local and regional dust dynamics and even connect to the global dust cycle. To budget total dust and to assess the impact of tillage, measurement of mobilized and transported dust is an essential but rare basis. In this study, a simple measurement concept with Modified Wilson and Cook samplers was applied for dust measurements on a small temporal and spatial scale on steep-slope vineyards in the Moselle area. Without mechanical impact, a mean horizontal flux of 0.01 g m2 min−1 was measured, while row tillage produced a mean horizontal flux of 5.92 g m2 min−1 of mobilized material and 4.18 g m2 min−1 emitted dust from site (=soil loss). Compared on this singular-event basis, emissions during tillage operations generated 99.89% of total emitted dust from the site under low mean wind velocities. The results also indicate a differing impact of specific cultivation operations, mulching, and tillage tools as well as the additional influence of environmental conditions, with highest emissions on dry soil and with additional wind impact. The dust source function is strongly associated with cultivation operations, implying highly dynamic but also regular and thus predictable and projectable emission peaks of total suspended particles. Detailed knowledge of the effects of mechanical impulses and reliable quantification of the local dust emission inventory are a basis for analysis of risk potential and choice of adequate management options.
The unrestrainable evolution of medical science and technology is drastically changing health-care, enabling new medical procedures and remedies, which are increasingly intertwined with moral principles. Although a uniform European approach on assisted suicide is lacking, a common trend is developing: the boundary between euthanasia, assisted suicide and end-of-life care and the frontiers of legitimate medicine are becoming increasingly blurred. In Italy, a ruling of the Constitutional Court, no. 242/2019, declared the partial unconstitutionality of article 580 of the Italian Criminal Code, which prohibited assistance in suicide.
Specifically, article 580 excluded the criminal liability for the person who, in the manner provided for in Articles 1 and 2 of the law 22 December 2017, no. 219, “facilitates the execution of intention of suicide, autonomously and freely formed, of one person kept alive by life-sustaining treatments and suffering from an irreversible pathology, source of physical or psychological suffering that he/she deems intolerable, but fully capable of making free aware decisions, provided that such conditions and methods of execution have been verified by a public structure of the national health service, following the opinion of the territorially competent ethics committee.” The present paper analyzes the legal regime of assisted suicide in Italy, the role of the rule of law, and the crucial boundary between the branches of government with regard to this delicate issue, and investigates current legal challenges and potential future legal tracks.
Introduction:In patients with common variable immunodeficiency (CVID),immunological response is compromised. Knowledge about COVID‐19 in CVIDpatients is sparse. We, here, synthesize current research addressing the level ofthreat COVID‐19posestoCVIDpatientsandthebest‐known treatments.
Method:Review of 14 publications.
Results:The number of CVID patients with moderate to severe (~29%) andcritical infection courses (~10%), and the number of fatal cases (~13%), areincreased compared to the general picture of COVID‐19 infection. However,this might be an overestimate. Systematic cohort‐wide studies are lacking, andasymptomatic or mild cases among CVID patients occur that can easily remainunnoticed. Regular immunoglobulin replacement therapy was administered inalmost all patients, potentially explaining why the numbers of critical and fatalcases were not higher. In addition, the application of convalescent plasma wasdemonstrated to have positive effects.
Conclusions:COVID‐19 poses an elevated threat to CVID patients. However,only systematic studies can provide robust information on the extent of thisthreat. Regular immunoglobulin replacement therapy is beneficial to combatCOVID‐19 in CVID patients, and best treatment after infection includes theuse of convalescent plasma in addition to common medication.
Background: Psychotherapy is successful for the majority of patients , but not for every patient. Hence, further knowledge is needed on how treatments should be adapted for those who do not profit or deteriorate. In the last years prediction tools as well as feedback interventions were part of a trend to more personalized approaches in psychotherapy. Research on psychometric prediction and feedback into ongoing treatment has the potential to enhance treatment outcomes, especially for patients with an increased risk of treatment failure or drop-out.rnMethods/design: The research project investigates in a randomized controlled trial the effectiveness as well as moderating and mediating factors of psychometric feedback to therapists. In the intended study a total of 423 patients, who applied for a cognitive-behavioral therapy at the psychotherapy clinic of the University Trier and suffer from a depressive and/or an anxietyrndisorder (SCID interviews), will be included. The patients will be randomly assigned either to one therapist as well as to one of two intervention groups (CG, IG2). An additional intervention group (IG1) will be generated from an existing archival data set via propensity score matching. Patients of the control group (CG; n = 85) will be monitored concerning psychological impairment but therapists will not be provided with any feedback about the patients assessments. In both intervention groups (IG1: n = 169; IG2: n = 169) the therapists are provided with feedback about the patients self-evaluation in a computerized feedback portal. Therapists of the IG2 will additionally be provided with clinical support tools, which will be developed in thisrnproject, on the basis of existing systems. Therapists will also be provided with a personalized treatment recommendation based on similar patients (Nearest Neighbors) at the beginning of treatment. Besides the general effectiveness of feedback and the clinical support tools for negatively developing patients, further mediating and moderating variables on this feedback effectrnshould be examined: treatment length, frequency of feedback use, therapist effects, therapist- experience, attitude towards feedback as well as congruence of therapist-andpatient- evaluation concerning the progress. Additional procedures will be implemented to assess treatment adherence as well as the reliability of diagnosis and to include it into the analyses.rnDiscussion: The current trial tests a comprehensive feedback system which combines precision mental health predictions with routine outcome monitoring and feedback tools in routine outpatient psychotherapy. It also adds to previous feedback research a stricter design by investigating another repeated measurement CG as well as a stricter control of treatment integrity. It also includes a structured clinical interview (SCID) and controls for comorbidity (within depression and anxiety). This study also investigates moderators (attitudes towards, use of the feedback system, diagnoses) and mediators (therapists" awareness of negative change and treatment length) in one study.
There are large health, societal, and economic costs associated with attrition from psychological services. The recently emerged, innovative statistical tool of complex network analysis was used in the present proof-of-concept study to improve the prediction of attrition. Fifty-eight patients undergoing psychological treatment for mood or anxiety disorders were assessed using Ecological Momentary Assessments four times a day for two weeks before treatment (3,248 measurements). Multilevel vector autoregressive models were employed to compute dynamic symptom networks. Intake variables and network parameters (centrality measures) were used as predictors for dropout using machine-learning algorithms. Networks for patients differed significantly between completers and dropouts. Among intake variables, initial impairment and sex predicted dropout explaining 6% of the variance. The network analysis identified four additional predictors: Expected force of being excited, outstrength of experiencing social support, betweenness of feeling nervous, and instrength of being active. The final model with the two intake and four network variables explained 32% of variance in dropout and identified 47 out of 58 patients correctly. The findings indicate that patients" dynamic network structures may improve the prediction of dropout. When implemented in routine care, such prediction models could identify patients at risk for attrition and inform personalized treatment recommendations.
Species can show strong variation of local abundance across their ranges. Recent analyses suggested that variation in abundance can be related to environmental suitability, as the highest abundances are often observed in populations living in the most suitable areas. However, there is limited information on the mechanisms through which variation in environmental suitability determines abundance. We analysed populations of the microendemic salamander Hydromantes flavus, and tested several hypotheses on potential relationships linking environmental suitability to population parameters. For multiple populations across the whole species range, we assessed suitability using species distribution models, and measured density, activity level, food intake and body condition index. In high-suitability sites, the density of salamanders was up to 30-times higher than in the least suitable ones. Variation in activity levels and population performance can explain such variation of abundance. In high-suitability sites, salamanders were active close to the surface, and showed a low frequency of empty stomachs. Furthermore, when taking into account seasonal variation, body condition was better in the most suitable sites. Our results show that the strong relationship between environmental suitability and population abundance can be mediated by the variation of parameters strongly linked to individual performance and fitness.
Leeches can parasitize many vertebrate taxa. In amphibians, leech parasitism often has potential detrimental effects including population decline. Most of studies on the host-parasite interactions involving leeches and amphibians focus on freshwater environments, while they are very scarce for terrestrial amphibians. In this work, we studied the relationship between the leech Batracobdella algira and the European terrestrial salamanders of the genus Hydromantes, identifying environmental features related to the presence of the leeches and their possible effects on the hosts. We performed observation throughout Sardinia (Italy), covering the distribution area of all Hydromantes species endemic to this island. From September 2015 to May 2017, we conducted >150 surveys in 26 underground environments, collecting data on 2629 salamanders and 131 leeches. Water hardness was the only environmental feature correlated with the presence of B. algira, linking this leech to active karstic systems. Leeches were more frequently parasitizing salamanders with large body size. Body Condition Index was not significantly different between parasitized and non-parasitized salamanders. Our study shows the importance of abiotic environmental features for host-parasite interactions, and poses new questions on complex interspecific interactions between this ectoparasite and amphibians.
The trophic niche is a life trait that identifies the consumer’s position in a local food web. Several factors, such as ontogeny, competitive ability and resource availability contribute in shaping species trophic niches. To date, information on the diet of European Hydromantes salamanders are only available for a limited number of species, no dietary studies have involved more than one species of the genus at a time, and there are limited evidences on how multiple factors interact in determining diet variation. In this study we examined the diet of multiple populations of six out of the eight European cave salamanders, providing the first data on the diet for five of them. In addition, we assessed whether these closely related generalist species show similar diet and, for each species, we tested whether season, age class or sex influence the number and the type of prey consumed. Stomach condition (empty/full) and the number of prey consumed were strongly related to seasonality and to the activity level of individuals. Empty stomachs were more frequent in autumn, in individuals far from cave entrance and in juveniles. Diet composition was significantly different among species. Hydromantes imperialis and H. supramontis were the most generalist species; H. flavus and H. sarrabusensis fed mostly on Hymenoptera and Coleoptera Staphylinidae, while H. genei and H. ambrosii mostly consumed Arachnida and Endopterygota larvae. Furthermore, we detected seasonal shifts of diet in the majority of the species examined. Conversely, within each species, we did not find diet differences between females, males and juveniles. Although being assumed to have very similar dietary habits, here Hydromantes species were shown to be characterized by a high divergence in diet composition and in the stomach condition of individuals.
The availability of data on the feeding habits of species of conservation value may be of great importance to develop analyses for both scientific and management purposes. Stomach flushing is a harmless technique that allowed us to collect extensive data on the feeding habits of six Hydromantes species. Here, we present two datasets originating from a three-year study performed in multiple seasons (spring and autumn) on 19 different populations of cave salamanders. The first dataset contains data of the stomach content of 1,250 salamanders, where 6,010 items were recognized; the second one reports the size of the intact prey items found in the stomachs. These datasets integrate considerably data already available on the diet of the European plethodontid salamanders, being also of potential use for large scale meta-analyses on amphibian diet.
In den letzten Jahren hat die Alternative für Deutschland (AfD) das Thema Wohnen zunehmend in ihren Wahlprogrammen aufgegriffen und für die eigene politische Profilierung genutzt. Der Beitrag zeigt, inwiefern die Thematisierung des Wohnens bei der AfD so formuliert ist, dass es erhebliche Anknüpfungspunkte an rechtes Gedankengut herstellt. Der Beitrag thematisiert die damit verbundenen Herausforderungen für eine kritische Stadtforschung sowie für progressive soziale Bewegungen. Er plädiert dafür, sich der Gefahr der rechten Vereinnahmung des Themas Wohnen bewusst zu sein und sich deutlich von den rechten Übernahmeversuchen abzugrenzen sowie Gegenstrategien zu entwickeln.
With the start of the Coronavirus (COVID-19) pandemic, the global education system has a faced immense challenges and disruptions resulting in and the necessity for an immediate redesign of teaching and learning in the school context. Face-to-face classroom instruction had to be replaced by ‘emergency remote teaching’, requiring teacher to adapt their daily routines to a new and unprecedented educational reality. Researchers and policymakers worldwide have agreed that, despite the fact that efforts were made to immediately adapt to emergency remote teaching, disadvantaged and vulnerable students may be especially at risk in emergency remote teaching. Given the differences in schooling organization across countries during the COVID-19 pandemic it can be expected that teachers performed inclusive instructional practices significantly different. Against the unpredictable situation, cross-country research has been urgently required to provide data that could inform education policy. Thus, this study explored teachers’ perceptions of supporting at risk students during the first COVID-19 school closures, as well as examining teachers’ inclusive teaching practices in three countries: Germany, Austria and Portugal. ANOVA results revealed important country differences. In general, it appears that teachers in Germany and Austria reported to have implemented less practices to address vulnerable and at-risk students compared to Portuguese teachers. Implications of the results, as well as further lines of research are outlined.
Background
The morphology of anuran larvae is suggested to differ between species with tadpoles living in standing (lentic) and running (lotic) waters. To explore which character combinations within the general tadpole morphospace are associated with these habitats, we studied categorical and metric larval data of 123 (one third of which from lotic environments) Madagascan anurans.
Results
Using univariate and multivariate statistics, we found that certain combinations of fin height, body musculature and eye size prevail either in larvae from lentic or lotic environments.
Conclusion
Evidence for adaptation to lotic conditions in larvae of Madagascan anurans is presented. While lentic tadpoles typically show narrow to moderate oral discs, small to medium sized eyes, convex or moderately low fins and non-robust tail muscles, tadpoles from lotic environments typically show moderate to broad oral discs, medium to big sized eyes, low fins and a robust tail muscle.
Although gravitropism forces trees to grow vertically, stems have shown to prefer specific orientations. Apart from wind deforming the tree shape, lateral light can result in prevailing inclination directions. In recent years a species dependent interaction between gravitropism and phototropism, resulting in trunks leaning down-slope, has been confirmed, but a terrestrial investigation of such factors is limited to small scale surveys. ALS offers the opportunity to investigate trees remotely. This study shall clarify whether ALS detected tree trunks can be used to identify prevailing trunk inclinations. In particular, the effect of topography, wind, soil properties and scan direction are investigated empirically using linear regression models. 299.000 significantly inclined stems were investigated. Species-specific prevailing trunk orientations could be observed. About 58% of the inclination and 19% of the orientation could be explained by the linear models, while the tree species, tree height, aspect and slope could be identified as significant factors. The models indicate that deciduous trees tend to lean down-slope, while conifers tend to lean leeward. This study has shown that ALS is suitable to investigate the trunk orientation on larger scales. It provides empirical evidence for the effect of phototropism and wind on the trunk orientation.
Determining the exact position of a forest inventory plot—and hence the position of the sampled trees—is often hampered by a poor Global Navigation Satellite System (GNSS) signal quality beneath the forest canopy. Inaccurate geo-references hamper the performance of models that aim to retrieve useful information from spatially high remote sensing data (e.g., species classification or timber volume estimation). This restriction is even more severe on the level of individual trees. The objective of this study was to develop a post-processing strategy to improve the positional accuracy of GNSS-measured sample-plot centers and to develop a method to automatically match trees within a terrestrial sample plot to aerial detected trees. We propose a new method which uses a random forest classifier to estimate the matching probability of each terrestrial-reference and aerial detected tree pair, which gives the opportunity to assess the reliability of the results. We investigated 133 sample plots of the Third German National Forest Inventory (BWI, 2011"2012) within the German federal state of Rhineland-Palatinate. For training and objective validation, synthetic forest stands have been modeled using the Waldplaner 2.0 software. Our method has achieved an overall accuracy of 82.7% for co-registration and 89.1% for tree matching. With our method, 60% of the investigated plots could be successfully relocated. The probabilities provided by the algorithm are an objective indicator of the reliability of a specific result which could be incorporated into quantitative models to increase the performance of forest attribute estimations.
The state-of-the-art finite element software Plaxis 3D was applied in a real-world study site of the Turaida castle mound to investigate the slope stability of the mound and understand the mechanisms triggering landslides there. During the simulation, the stability of the castle mound was analysed and the most landslide-susceptible zones of hillslopes were determined. The 3D finite-element stability analysis has significant advantages over conventional 2D limit-equilibrium methods where locations of 2D stability sections are arbitrarily selected. Two modelling scenarios of the slope stability were elaborated considering deep-seated slides in bedrock and shallow landslides in the colluvial material of slopes. The model shows that shallow slides in colluvium are more probable. In the finite-element model, slope failure occurs along the weakest zone in colluvium, similarly to the situation observed in previous landslides in the study site. The physical basis of the model allows results to be obtained very close to natural conditions and delivers valuable insight in triggering mechanisms of landslides.
Background
In light of the current biodiversity crisis, DNA barcoding is developing into an essential tool to quantify state shifts in global ecosystems. Current barcoding protocols often rely on short amplicon sequences, which yield accurate identification of biological entities in a community but provide limited phylogenetic resolution across broad taxonomic scales. However, the phylogenetic structure of communities is an essential component of biodiversity. Consequently, a barcoding approach is required that unites robust taxonomic assignment power and high phylogenetic utility. A possible solution is offered by sequencing long ribosomal DNA (rDNA) amplicons on the MinION platform (Oxford Nanopore Technologies).
Findings
Using a dataset of various animal and plant species, with a focus on arthropods, we assemble a pipeline for long rDNA barcode analysis and introduce a new software (MiniBar) to demultiplex dual indexed Nanopore reads. We find excellent phylogenetic and taxonomic resolution offered by long rDNA sequences across broad taxonomic scales. We highlight the simplicity of our approach by field barcoding with a miniaturized, mobile laboratory in a remote rainforest. We also test the utility of long rDNA amplicons for analysis of community diversity through metabarcoding and find that they recover highly skewed diversity estimates.
Conclusions
Sequencing dual indexed, long rDNA amplicons on the MinION platform is a straightforward, cost-effective, portable, and universal approach for eukaryote DNA barcoding. Although bulk community analyses using long-amplicon approaches may introduce biases, the long rDNA amplicons approach signifies a powerful tool for enabling the accurate recovery of taxonomic and phylogenetic diversity across biological communities.
This intervention study explored the effects of a newly developed intergenerational encounter program on cross-generational age stereotyping (CGAS). Based on a biographical-narrative approach, participants (secondary school students and nursing home residents) were invited to share ideas about existential questions of life (e.g., about one’s core experiences, future plans, and personal values). Therefore, the dyadic Life Story Interview (LSI) had been translated into a group format (the Life Story Encounter Program, LSEP), consisting of 10 90-min sessions. Analyses verified that LSEP participants of both generations showed more favorable CGAS immediately after, but also 3 months after the program end. Such change in CGAS was absent in a control group (no LSEP participation). The LSEP-driven short- and long-term effects on CGAS could be partially explained by two program benefits, the feeling of comfort with and the experience of learning from the other generation.

The present study examined associations between fathers’ masculinity orientation and their anticipated reaction toward their child’s coming out as lesbian or gay (LG). Participants were 134 German fathers (28 to 60years) of a minor child. They were asked how they would personally react if, one day, their child disclosed their LG identity to them. As hypothesized, fathers with a stronger masculinity orientation (i.e., adherence to traditional male gender norms, such as independence, assertiveness, and physical strength) reported that they would be more likely to reject their LG child. This association was serially mediated by two factors: fathers’ general anti-LG attitudes (i.e., level of homophobia) and their emotional distress due to their child’s coming out (e.g., feelings of anger, shame, or sadness). The result pattern was independent of the child’s gender or age. The discussion centers on the problematic role of traditional masculinity when it comes to fathers’ acceptance of their non-heterosexual child.
This paper mainly studies two topics: linear complementarity problems for modeling electricity market equilibria and optimization under uncertainty. We consider both perfectly competitive and Nash–Cournot models of electricity markets and study their robustifications using strict robustness and the -approach. For three out of the four combinations of economic competition and robustification, we derive algorithmically tractable convex optimization counterparts that have a clear-cut economic interpretation. In the case of perfect competition, this result corresponds to the two classic welfare theorems, which also apply in both considered robust cases that again yield convex robustified problems. Using the mentioned counterparts, we can also prove the existence and, in some cases, uniqueness of robust equilibria. Surprisingly, it turns out that there is no such economic sensible counterpart for the case of -robustifications of Nash–Cournot models. Thus, an analog of the welfare theorems does not hold in this case. Finally, we provide a computational case study that illustrates the different effects of the combination of economic competition and uncertainty modeling.
Intense, southward low-level winds are common in Nares Strait, between Ellesmere Island and northern Greenland. The steep topography along Nares Strait leads to channelling effects, resulting in an along-strait flow. This research study presents a 30-year climatology of the flow regime from simulations of the COSMO-CLM climate model. The simulations are available for the winter periods (November–April) 1987/88 to 2016/17, and thus, cover a period long enough to give robust long-term characteristics of Nares Strait. The horizontal resolution of 15 km is high enough to represent the complex terrain and the meteorological conditions realistically. The 30-year climatology shows that LLJs associated with gap flows are a climatological feature of Nares Strait. The maximum of the mean 10-m wind speed is around 12 m s-1 and is located at the southern exit of Smith Sound. The wind speed is strongly related to the pressure gradient. Single events reach wind speeds of 40 m s-1 in the daily mean. The LLJs are associated with gap flows within the narrowest parts of the strait under stably stratified conditions, with the main LLJ occurring at 100–250 m height. With increasing mountain Froude number, the LLJ wind speed and height increase. The frequency of strong wind events (>20 m s-1 in the daily mean) for the 10 m wind shows a strong interannual variability with an average of 15 events per winter. Channelled winds have a strong impact on the formation of the North Water polynya.
Redox-driven biogeochemical cycling of iron plays an integral role in the complex process network of ecosystems, such as carbon cycling, the fate of nutrients and greenhouse gas emissions. We investigate Fe-(hydr)oxide (trans)formation pathways from rhyolitic tephra in acidic topsoils of South Patagonian Andosols to evaluate the ecological relevance of terrestrial iron cycling for this sensitive fjord ecosystem. Using bulk geochemical analyses combined with micrometer-scale-measurements on individual soil aggregates and tephra pumice, we document biotic and abiotic pathways of Fe released from the glassy tephra matrix and titanomagnetite phenocrysts. During successive redox cycles that are controlled by frequent hydrological perturbations under hyper-humid climate, (trans)formations of ferrihydrite-organic matter coprecipitates, maghemite and hematite are closely linked to tephra weathering and organic matter turnover. These Fe-(hydr)oxides nucleate after glass dissolution and complexation with organic ligands, through maghemitization or dissolution-(re)crystallization processes from metastable precursors. Ultimately, hematite represents the most thermodynamically stable Fe-(hydr)oxide formed under these conditions and physically accumulates at redox interfaces, whereas the ferrihydrite coprecipitates represent a so far underappreciated terrestrial source of bio-available iron for fjord bioproductivity. The insights into Fe-(hydr)oxide (trans)formation in Andosols have implications for a better understanding of biogeochemical cycling of iron in this unique Patagonian fjord ecosystem.
