Evidence points to autonomy as having a place next to affiliation, achievement, and power as one of the basic implicit motives; however, there is still some research that needs to be conducted to support this notion.
The research in this dissertation aimed to address this issue. I have specifically focused on two issues that help solidify the foundation of work that has already been conducted on the implicit autonomy motive, and will also be a foundation for future studies. The first issue is measurement. Implicit motives should be measured using causally valid instruments (McClelland, 1980). The second issue addresses the function of motives. Implicit motives orient, select, and energize behavior (McClelland, 1980). If autonomy is an implicit motive, then we need a valid instrument to measure it and we also need to show that it orients, selects, and energizes behavior.
In the following dissertation, I address these two issues in a series of ten studies. Firstly, I present studies that examine the causal validity of the Operant Motive Test (OMT; Kuhl, 2013) for the implicit affiliation and power motives using established methods. Secondly, I developed and empirically tested pictures to specifically assess the implicit autonomy motive and examined their causal validity. Thereafter, I present two studies that investigated the orienting and energizing effects of the implicit autonomy motive. The results of the studies solidified the foundation of the OMT and how it measures nAutonomy. Furthermore, this dissertation demonstrates that nAutonomy fulfills the criteria for two of the main functions of implicit motives. Taken together, the findings of this dissertation provide further support for autonomy as an implicit motive and a foundation for intriguing future studies.
Vor dem Hintergrund eines fachlichen und gesellschaftlichen Interesses an psychologischen Forschungsthemen wurde der Einsatz von Topic Modeling zu deren automatisierten und validen Identifikation erprobt und mit einem traditionellen Ansatz verglichen, der auf Klassifikationskategorien von Fachdatenbanken beruht. Kern der Arbeit sind drei Studien mit unterschiedlichen Anwendungsszenarien: (1) Die Ermittlung psychologischer Brennpunktthemen, (2) das Verhältnis zwischen gesellschaftlichen Herausforderungen und Themen der psychologischen Fachliteratur sowie (3) die Forschungsinteressen von Psychologinnen und Psychologen. In jeder dieser Studien wurden sukzessive neue methodische Schwerpunkte gesetzt. Die Erkenntnisse daraus flossen in die Entwicklung einer nutzerfreundlichen App zur Exploration und Analyse von psychologischen Forschungsthemen ein. Im Vergleich mit dem klassifikationsbasierten Ansatz erwies sich Topic Modeling als Methode der Wahl zur automatisierten und differenzierten Identifikation psychologischer Forschungsthemen. Zur externen Validierung der Themeninhalte stellte sich ein Klassifikationssystem für psychologische Fachliteratur jedoch als geeignet heraus. Einschränkungen, Implikationen für weitere Forschung sowie Folgerungen für die Weiterentwicklung digitaler Produkte von forschungsbasierten Infrastruktureinrichtungen in der Psychologie werden diskutiert. Abschließend wird eine Entscheidungsheuristik zur Auswahl geeigneter Topic-Modeling-Varianten im Kontext von Forschungsthemen vorgelegt.
The present thesis is devoted to a construction which defies generalisations about the prototypical English noun phrase (NP) to such an extent that it has been termed the Big Mess Construction (Berman 1974). As illustrated by the examples in (1) and (2), the NPs under study involve premodifying adjective phrases (APs) which precede the determiner (always realised in the form of the indefinite article a(n)) rather than following it.
(1) NoS had not been hijacked – that was too strong a word. (BNC: CHU 1766)
(2) He was prepared for a battle if the porter turned out to be as difficult a customer as his wife. (BNC: CJX 1755)
Previous research on the construction is largely limited to contributions from the realms of theoretical syntax and a number of cursory accounts in reference grammars. No comprehensive investigation of its realisations and uses has as yet been conducted. My thesis fills this gap by means of an exhaustive analysis of the construction on the basis of authentic language data retrieved from the British National Corpus (BNC). The corpus-based approach allows me to examine not only the possible but also the most typical uses of the construction. Moreover, while previous work has almost exclusively focused on the formal realisations of the construction, I investigate both its forms and functions.
It is demonstrated that, while the construction is remarkably flexible as concerns its possible realisations, its use is governed by probabilistic constraints. For example, some items occur much more frequently inside the degree item slot than others (as, too and so stand out for their particularly high frequency). Contrary to what is assumed in most previous descriptions, the slot is not restricted in its realisation to a fixed number of items. Rather than representing a specialised structure, the construction is furthermore shown to be distributed over a wide range of possible text types and syntactic functions. On the other hand, it is found to be much less typical of spontaneous conversation than of written language; Big Mess NPs further display a strong preference for the function of subject complement. Investigations of the internal structural complexity of the construction indicate that its obligatory components can optionally be enriched by a remarkably wide range of optional (if infrequent) elements. In an additional analysis of the realisations of the obligatory but lexically variable slots (head noun and head of AP), the construction is highlighted to represent a productive pattern. With the help of the methods of Collexeme Analysis (Stefanowitsch and Gries 2003) and Co-varying Collexeme Analysis (Gries and Stefanowitsch 2004b, Stefanowitsch and Gries 2005), the two slots are, however, revealed to be strongly associated with general nouns and ‘evaluative’ and ‘dimension’ adjectives, respectively. On the basis of an inspection of the most typical adjective-noun combinations, I identify the prototypical semantics of the Big Mess Construction.
The analyses of the constructional functions centre on two distinct functional areas. First, I investigate Bolinger’s (1972) hypothesis that the construction fulfils functions in line with the Principle of Rhythmic Alternation (e.g. Selkirk 1984: 11, Schlüter 2005). It is established that rhythmic preferences co-determine the use of the construction to some extent, but that they clearly do not suffice to explain the phenomenon under study. In a next step, the discourse-pragmatic functions of the construction are scrutinised. Big Mess NPs are demonstrated to perform distinct information-structural functions in that the non-canonical position of the AP serves to highlight focal information (compare De Mönnink 2000: 134-35). Additionally, the construction is shown to place emphasis on acts of evaluation. I conclude the construction to represent a contrastive focus construction.
My investigations of the formal and functional characteristics of Big Mess NPs each include analyses which compare individual versions of the construction to one another (e.g. the As Big a Mess, Too Big a Mess and So Big a Mess Constructions). It is revealed that the versions are united by a shared core of properties while differing from one another at more abstract levels of description. The question of the status of the constructional versions as separate constructions further receives special emphasis as part of a discussion in which I integrate my results into the framework of usage-based Construction Grammar (e.g. Goldberg 1995, 2006).
Les régions transfrontalières sont souvent des laboratoires de circulation d’idées et de pratiques. Cet article se demande si, dans le Grand Genève il est possible de transposer le modèle de logement coopératif, assez développé en Suisse, dans le contexte français, où ce type d’habitat est moins pratiqué. A partir de l’exemple de Viry, commune française sise dans le périmètre institutionnel du Grand Genève, l’article analyse les possibilités et les limites d’une telle transposition. Les résultats montrent la difficulté à émuler un contexte propre à reproduction du modèle suisse de coopératives en France. Les différences législatives et institutionnelles, mais aussi culturelles sur le rapport au logement dans ses différentes dimensions sont autant d’obstacles pour reproduire à l’identique en France des modalités éprouvées de construction du logement coopératif en Suisse. Il est ainsi nécessaire de procéder à des adaptations créatives de différents ordres pour que le modèle puisse trouver une place dans le nouveau contexte.
Up-to-date information about the type and spatial distribution of forests is an essential element in both sustainable forest management and environmental monitoring and modelling. The OpenStreetMap (OSM) database contains vast amounts of spatial information on natural features, including forests (landuse=forest). The OSM data model includes describing tags for its contents, i.e., leaf type for forest areas (i.e., leaf_type=broadleaved). Although the leaf type tag is common, the vast majority of forest areas are tagged with the leaf type mixed, amounting to a total area of 87% of landuse=forests from the OSM database. These areas comprise an important information source to derive and update forest type maps. In order to leverage this information content, a methodology for stratification of leaf types inside these areas has been developed using image segmentation on aerial imagery and subsequent classification of leaf types. The presented methodology achieves an overall classification accuracy of 85% for the leaf types needleleaved and broadleaved in the selected forest areas. The resulting stratification demonstrates that through approaches, such as that presented, the derivation of forest type maps from OSM would be feasible with an extended and improved methodology. It also suggests an improved methodology might be able to provide updates of leaf type to the OSM database with contributor participation.
In dem Gebiet der Informationsextraktion angesiedelt kombiniert diese Arbeit mehrere Verfahren aus dem Bereich des maschinellen Lernens. Sie stellt einen neuen Algorithmus vor, der teil-überwachtes Lernen mit aktivem Lernen verknüpft. Ausgangsbasis ist die Analyse der Daten, indem sie in mehrere Sichten aufgeteilt werden. Hier werden die Eingaben verschiedener Personen unterteilt. Jeweils getrennt voneinander erzeugt der Algorithmus mittels Klassifizierern Modelle, die aus den individuellen Auszeichnungen der Personen aufgebaut werden. Um die dafür benötigte Datenmenge zu erhalten wird Crowdsourcing genutzt, dass es ermöglicht eine große Anzahl an Personen zu erreichen. Die Personen erhalten die Aufgabe, Texte zu annotieren. Einerseits wird dies initial für einen historischen Textkorpus vorgenommen. Dabei wird aufgeführt, welche Schritte notwendig sind, um die Annotationsaufgabe in Crowdsourcing-Portalen zur Bearbeitung anzubieten und durchzuführen. Andererseits wird ein aktueller Datensatz von Kurznachrichten genutzt. Der Algorithmus wird auf diese Beispieldatensätze angewandt. Durch Experimente wird die Ermittlung der optimalen Parameterauswahl durchgeführt. Außerdem werden die Ergebnisse mit den Resultaten bisheriger Algorithmen verglichen.
Im Rahmen eines Lehrforschungsprojekts setzten sich Studierende der Angewandten Geographie an der Universität Trier über zwei Semester in den Jahren 2016 und 2017 mit der Anpassung an den Klimawandel im Weinbau auseinander. Ziel des Lehrforschungsprojektes war es, besser zu verstehen wie Winzer*innen den Klimawandel wahrnehmen, welche Rolle der Klimawandel in (betrieblichen) Entscheidungen spielt und welche Anpassungspraktiken bereits beobachtbar sind.Der vorliegende Bericht fasst einige Ergebnisse der empirischen Untersuchung knapp zusammen.
Digitalisierung wirkt sich in radikaler Weise auf alle Lebensbereiche aus. Durch die technische Vernetzung und die Umwandlung analoger in digitale Daten entstehen umfassende Datenmengen. Aus ihrer Verknüpfung und Verarbeitung lassen sich Regelmäßigkeiten erkennen und Anwendungen generieren, deren soziale, ethische, politische, rechtliche, arbeitsweltliche und ökonomische Folgen heute noch nicht ansatzweise abzuschätzen sind.
La numérisation a des répercussions non négligeables sur tous les aspects de la vie. La mise en réseau technique et la conversion de données analogiques en données numériques sont à l’origine d’énormes quantités de données. Il est possible d’identifier des régularités dans leur mise en rapport et leur traitement, et de générer des applications dont les conséquences sociales, éthiques, politiques, juridiques, professionnelles et économiques sont encore difficiles à évaluer.
The dissertation includes three published articles on which the development of a theoretical model of motivational and self-regulatory determinants of the intention to comprehensively search for health information is based. The first article focuses on building a solid theoretical foundation as to the nature of a comprehensive search for health information and enabling its integration into a broader conceptual framework. Based on subjective source perceptions, a taxonomy of health information sources was developed. The aim of this taxonomy was to identify most fundamental source characteristics to provide a point of reference when it comes to relating to the target objects of a comprehensive search. Three basic source characteristics were identified: expertise, interaction and accessibility. The second article reports on the development and evaluation of an instrument measuring the goals individuals have when seeking health information: the ‘Goals Associated with Health Information Seeking’ (GAINS) questionnaire. Two goal categories (coping focus and regulatory focus) were theoretically derived, based on which four goals (understanding, action planning, hope and reassurance) were classified. The final version of the questionnaire comprised four scales representing the goals, with four items per scale (sixteen items in total). The psychometric properties of the GAINS were analyzed in three independent samples, and the questionnaire was found to be reliable and sufficiently valid as well as suitable for a patient sample. It was concluded that the GAINS makes it possible to evaluate goals of health information seeking (HIS) which are likely to inform the intention building on how to organize the search for health information. The third article describes the final development and a first empirical evaluation of a model of motivational and self-regulatory determinants of an intentionally comprehensive search for health information. Based on the insights and implications of the previous two articles and an additional rigorous theoretical investigation, the model included approach and avoidance motivation, emotion regulation, HIS self-efficacy, problem and emotion focused coping goals and the intention to seek comprehensively (as outcome variable). The model was analyzed via structural equation modeling in a sample of university students. Model fit was good and hypotheses with regard to specific direct and indirect effects were confirmed. Last, the findings of all three articles are synthesized, the final model is presented and discussed with regard to its strengths and weaknesses, and implications for further research are determined.
