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 ...

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 ...

The role of sustainability in capital markets
(2023)
This doctoral thesis explores capital market sustainability, focusing on the European capital market.
The work takes two different angles, either from the investors perspective while subsequently examining if reported ESG activities and an ESG rating's sustainability performance affect a company's valuation or risk.

Microfluidics Based 3D Printed Reconfigurable Antenna for K-Band Applications
(2023)
In dieser Arbeit werden neuartige mikrofluid-basierte, rekonfigurierbare Antennen für Mikrowellen-Anwendungen vorgestellt. Ebenfalls vorgestellt wird eine kosteneffektive Methode zur ultra-breitbandigen Erhöhung (definiert als Bandbreite von 20% oder höher als die zentrale Frequenz) des Antennengewinns basierend auf dielektrischen Linsen. Zunächst wird dabei ein fest-verdrahtetes Design entwickelt. Diese Antenne verwendet kapazitive Lasten, um die -10 dB Bandbreite um den Faktor 2.5 (+150%) zu erhöhen. Die vorgeschlagene ...

Denaturation mechanism of whey protein by using the hot extrusion technology
(2022-02)
Milk proteins are one of the heat-sensitive nutritional components, especially whey proteins changing their structure through thermal treatment, consequently denaturizing and aggregating. The transformation of native whey proteins structure in presence of shear stress resulted in the microparticulation, which affected the functional properties. Many authors investigated these parameters with different conditions; however, understanding the combination of relevant parameters of the microparticulation process of whey ...

Removing Barriers for Integrating Dimensional Conceptualisations of Personality Disorders into Clinical Practice
(2023)
The present dissertation investigated the utility of dimensional personality disorder (PD) models for clinical practice, specifically focusing on the Alternative Model of Personality Disorders (AMPD) as implemented in the DSM-5 and the dimensional PD conceptualization in the ICD-11. The dissertation research consisted of three studies that addressed various aspects of clinical utility of dimensional PD models, including practical utility regarding assessment of the severity of personality pathology, the quantification ...

Towards a Better Understanding of Entrepreneurial Teams: Investigating Temporal Dynamics on Multiple Levels
(2023)
This dissertation investigates entrepreneurial teams in the process of creating new ventures. The new venture creation process is complex. Different actors impact the new venture creation process in various ways, either facilitating or complicating it. The three studies at the heart of this thesis aim to cut through this complexity by examining the social context (i.e., entrepreneurial teams) and the temporal dynamics occurring in more detail. All studies address the conditions underpinning entrepreneurial teamwork ...

Learning through Self-Explanation
(2023)
In this dissertation, the effectiveness of learning through self-explanation was examined through a series of experiments. The primary focus was on the acquisition of factual knowledge. Learners' self-explanations were coded and categorized into correct inferences, correct paraphrases, and false utterances.

Process optimisation and non-destructive quality attributes monitoring during drying: A case study of celeriac slices and characterisation of its powder
(2023)
This study investigated strategies applied in drying technology to produce an optimised quality of plant-sourced food while considering environmental and sustainability aspects based on a case study of celeriac and powder, respectively. The I-optimal design of response surface methodology with 30 experiment runs was applied for process optimisation. Pre-drying treatments (blanching at 85 °C, 3 min; dipping in 1% citric acid solution, 3 min; no pre-drying treatment), drying temperatures (50, 60, and 70 °C), air ...

Analysis of agricultural landscape transformation and cropping system diversification in southern Myanmar
(2023)
Myanmar's forests are rich in biodiversity and have significant potential for carbon reduction. Kyunsu Township in southern Myanmar is still covered by biodiverse tropical evergreen rainforests on the highlands and mangroves on the coastline, conserving carbon stocks. However, the expansion of croplands into these forests to meet the growing demand for food and crop income is a major driver of deforestation and loss of carbon sinks. Thus, balancing agricultural land use and natural resource conservation is vital for ...
