B/ordering the Anthropocene: Inter- and Transdisciplinary Perspectives on Nature-Culture Relations
(2020)
In and with this thematic issue we would like to invite you to engage in productive boundary work and to critically examine the relationship between nature and culture in the Anthropocene. A few years ago, the term Anthropocene was proposed by Paul Crutzen as a term for the current geological epoch, in which humankind (the ‘anthropos’) is seen as the central driving force for global changes in ecological systems. This epoch is characterized by the blurring of boundaries between society and nature, science and politics, as well as by the increased drawing of boundaries between social groups, lifestyles, and the Global North and Global South. With this issue, we would like to give an impetus to explore boundary phenomena in the relationship between nature and society, which up to now have not been the focus of Border Studies. The challenges and problems of the Anthropocene require cross-border thinking and research that stimulates a new reflexivity and commitment, to which the multidisciplinary field of Border Studies can contribute.
The parameterization of the boundary layer is a challenge for regional climate models of the Arctic. In particular, the stable boundary layer (SBL) over Greenland, being the main driver for substantial katabatic winds over the slopes, is simulated differently by different regional climate models or using different parameterizations of the same model. However, verification data sets with high-resolution profiles of the katabatic wind are rare. In the present paper, detailed aircraft measurements of profiles in the katabatic wind and automatic weather station data during the experiment KABEG (Katabatic wind and boundary-layer front experiment around Greenland) in April and May 1997 are used for the verification of the regional climate model COSMO-CLM (CCLM) nested in ERA-Interim reanalyses. CCLM is used in a forecast mode for the whole Arctic with 15 km resolution and is run in the standard configuration of SBL parameterization and with modified SBL parameterization. In the modified version, turbulent kinetic energy (TKE) production and the transfer coefficients for turbulent fluxes in the SBL are reduced, leading to higher stability of the SBL. This leads to a more realistic representation of the daily temperature cycle and of the SBL structure in terms of temperature and wind profiles for the lowest 200 m.
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.
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.
Das Grundgesetz ist keine bloße Neuauflage, sondern vielmehr eine Weiterentwicklung der Weimarer Reichsverfassung. Obwohl dem Namen nach gar keine „Verfassung“, wird das Grundgesetz spätestens seit der Wiedervereinigung nicht mehr als vorläufige, sondern als endgültige gesamtdeutsche Verfassung angesehen. Strikte Gewaltenteilung, Rechtsstaatlichkeit, umfassender Grundrechtsschutz und die Einführung der sog. „Ewigkeitsklausel“ (Art. 79 Abs. 3 GG) sind nur einige Elemente, mit denen „Bonn“ korrigierte, was „Weimar“ noch nicht vermochte. Nicht zuletzt die umfangreiche Rechtsprechung des Bundesverfassungsgerichts hat das Grundgesetz zu dem umfassenden Regelwerk gemacht, das nunmehr 70 Jahre ohne eine größere Verfassungskrise überdauert hat.
Die in dieser Ausgabe zusammengefassten Beiträge, die im Mai 2019 im Rahmen einer Festveranstaltung im Rokoko-Saal der Aufsichts- und Dienstleistungsdirektion in Trier gehalten wurden, beleuchten aus unterschiedlichen Perspektiven die Hintergründe der deutschen Verfassungsrechtsgeschichte und bieten eine Bestandsaufnahme über aktuelle Entwicklungen.
Aider les jeunes à s’exprimer constitue un volet important de l’éducation à la démocratie. Dans ce contexte, une des méthodes consiste à laisser les jeunes concevoir les médias qu’ils/elles connaissent le mieux. Cet article examine essentiellement comment mettre en relation le travail de projet créatif avec les médias numériques, et plus précisément, le smartphone.
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 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.
"Ich habe nichts zu verstecken ... oder doch?!" - Ein Praxisleitfaden zur Diskussion in der Klasse
(2020)
Durch das Zusammenspiel von Big Data und künstlicher Intelligenz eröffnen sich ganz neue Möglichkeiten, auch im Bereich der öffentlichen Sicherheit. Immer mehr Städte weltweit machen davon Gebrauch und setzen auf Kameras mit computergesteuerter Gesichtserkennung. Nicht jeder ist damit einverstanden. Wie kann man die aktuelle gesellschaftliche Debatte um öffentliche Sicherheit und Privatsphäre mit Jugendlichen besprechen?
„Die Demokratisierung von Schulen ist uns ein großes Anliegen“, beschreibt Lucia Wagner eines ihrer Hauptmotive für das Engagement in der rheinland-pfälzischen Schülervertretung. Für mateneen sprach Maike Koböck mit ihr und weiteren Schülervertreter*innen aus Luxemburg und dem Saarland über ihre Erfahrungen.
