Herausforderungen bei der Analyse von Unterrichtsqualität und deren Wirkungen auf Lernende
(2023-07)
Die empirische Unterrichtsforschung stellt Forschende vor zahlreiche Herausforderungen. Eine besondere Herausforderung besteht darin, dass wissenschaftliche Ergebnisse in hohem Maße von den Entscheidungen der Forschenden im Forschungsprozess abhängen – ein informiertes Vorgehen ist für jeden Schritt guter wissenschaftlicher Forschung fundamental. Ziel der kumulativen Dissertation ist es daher, aus einer Metaperspektive theoretisch-konzeptionelle Grundlagen und forschungsmethodische Fragen der Unterrichtsforschung zu ...

„Jetzt kommt da so ne fremde Frau.“ Eine qualitative Analyse zur Beziehungsgestaltung in der ehrenamtlichen Betreuung von Menschen mit Demenz
(2023-06)
Angesichts der steigenden Demenzprävalenz gilt die Sicherstellung einer angemessenen Versorgung von Menschen mit Demenz als besondere Herausforderung unserer Zeit. Um die häusliche Sorge zu stärken und pflegende Angehörig zu entlasten, bietet die Pflegeversicherung Betreuungsleistungen als niedrigschwellige Unterstützung an. Nach § 45a SGB XI können Ehrenamtliche diese Leistung erbringen und Menschen mit Demenz stundenweise betreuen.
Die Dissertation stellt die bislang kaum erforschte soziale Beziehung zwischen den ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Situative Teams in Cooperative Autonomous Systems
(2023)
Distributed systems have been established in many areas of IT and will play an even more significant role in the future. Such systems are no longer limited to specific fields of application but interconnect many different domains. They encompass, e. g. Cloud Computing, Internet of Things, service robotics, and autonomous vehicles. The integrated sub-systems communicate in order to exchange information and, if necessary, perform tasks together. Moreover, the number of interconnected sub-systems is constantly growing. ...

Control of Open Quantum Systems: Examples & Methods for Non-Markovian Dynamics
(2023)
Usually open quantum systems are considered to be under the influence of noise and therefore faulty. On the other hand, a controlled system is regarded as something stable and predictable. It is often neglected, that the two aspects are very closely related. A perfectly isolated quantum system will not be subject to environmental influences, but this makes it also impossible to interact with it in any manner. Controlling and measuring such a system is impossible and therefore of no technical relevance. Every system ...

Conputational Linguistic Approach to Implicit Sentiment Analysis: Politeness and Sentiment Interaction
(2022)
Sentiment analysis is a hot topic in many research fields such as linguistics, computer science and marketing. With the development of technology, machines can reach very high performance on explicit sentiment analysis both sentence-level and aspect-level. The role of computational linguists has also changed from handcrafting scoring rules to guide training data annotation as the algorithms are developed from rule-based scoring to deep learning models that can extract language features themselves. Moreover, research ...

Numerical simulation of a sub-wavelength plasmonic THz antenna for bio-sensing applications
(2023)
In the past decades, bio-sensing has become a steadily growing field in the life-sciences. Popular subjects of investigation are proteins, which for instance mediate intra-cellular transfer of substances and thus are attractive drug targets. They are also responsible for the occurence of degenerative diseases such as Alzheimer’s disease and the Creutzfeld-Jakob disease. Examining proteins to uncover their fundamental properties and behavior is important in order to advance modern health care and medicine. One way to ...
Dissertation
Development of a new methodology in sensory science to detect the intention-behaviour gap in organic food consumption and investigate the effect of this gap on consumer’s subjective wellbeing
(2020-08)
Aktuelle Umweltherausforderungen wie die globale Erwärmung, der Klimawandel und der Verlust der biologischen Vielfalt und der natürlichen Ressourcen hängen mit dem Verhalten der Menschen zusammen. Nicht nachhaltige Produktion und Konsum erklären die meisten dieser Herausforderungen. Daher interessieren sich immer mehr Verbraucher für Bio-Lebensmittel, um ihr Engagement für ein nachhaltigeres Lebensmittelverhalten zu demonstrieren. Infolgedessen ist der Markt für Bio-Lebensmittel in letzter Zeit gewachsen. Verbraucher ...

Community-Based Associations and Rural Development in Rwanda: A Local Perspective on the Contribution of Social Capital to Human Capabilities
(2022)
The post-World War II political discourse around development has stimulated academic debates in recent decades. While some of these debates simply aim to transform the development mainstream, many others among the post-colonial thinkers are more critical of and even reject mainstream development ideologies. Despite the valuable academic debates, most development practitioners seem to have remained unresponsive to some of the allegations. Their concept is incorporated in much of the contemporary political narratives ...

Transforming towards a sustainable circular economy: exploring the social dimension, actor contribution and emerging paradoxes
(2023)
Pressing global societal challenges highlight organisational vulnerability and the need to transform towards more sustainable production and consumption measures. The circular economy concept is considered an alternative to the prevalent linear economic system. It aims to contribute to sustainable development by slowing and closing resource cycles and facilitating cross-sectoral collaboration of multiple stakeholders. Yet, the desired transformation is lagging behind and the current debate focuses primarily on the ...
