Consumers’ Disposal Behavior at the Base of the Pyramid
(2024)
This dissertation explores the sources of sustainable waste management by examining the disposal behavior of low-income consumers at the base of the pyramid (BoP). Consumer product and package disposal behavior varies internationally and requires a selective strategy for waste management at the BoP. Uniform approaches to waste management have proven inadequate, as BoP markets are complex and heterogeneous and thus need to be considered individually.
Therefore, this dissertation focuses on identifying factors influence ...

Static and Dynamic Characterization of MEMS Micromirror and Microshutter arrays: Reliability and Lifetime
(2024)
Buildings are responsible for 40 % of the primary energy consumption and 36 % of the total CO2 emissions. There is a huge potential to decrease energetic consumption for lighting and heating/cooling by substituting the 85 % of inefficient glazing areas in EU’s buildings with energy efficient smart glazing windows. A micro-electro-mechanical system (MEMS) based smart glazing system comprising of millions of micro mirrors (invisible to the bare eye) is investigated here. This concept allows dynamic light steering by ...

Literatur- und Filmberichterstattung als journalistisches Feld
(2024)
Die interdisziplinäre Studie „Literatur- und Filmberichterstattung als journalistisches Feld: Vampir-Narrative in deutschen Feuilletons“ nimmt zwei Tendenzen der Berichterstattung über kinder- und jugendzentrierte Vampir-Narrative in den deutschen Feuilletons in den Blick. Sie weist nach, dass sowohl die negative Berichterstattung über jugendzentrierte Vampir-Narrative wie Twilight oder The Vampire Diaries als auch die positiven Artikel über kinderzentrierte Vampir-Narrative wie Der kleine Vampir oder Die Vampirschwestern ...

Ordoliberalism and the Making of the Economic Constitution: State, Law, and Money in the Market Economy
(2023)
The aim of my research is to explore the political economy of ordoliberalism in its historical trajectory. Beginning from the years of its inception during the interwar period, the dissertation focuses on the specific conditions and political economy of the Weimar Republic as the framework within which the ordoliberal framework was developed. Moving on to the postwar period, the dissertation examines the attempts of operationalization of the ordoliberal framework within the context of West Germany and the social ...

Biases im Planungsprozess
(2023)
Die vorliegende Arbeit befasst sich mit der Frage nach der Relevanz und der Diagnostizierbarkeit kognitiver, motivationaler und gruppendynamischer Biases im Kontext organisationaler Planungsprozesse. Ziel der Arbeit war es, einen Fragebogen zu entwickeln, der die Anfälligkeit von Gruppen für derartige Biases erfasst und damit einen Indikator für die Qualität von Planungsprozessen darstellt.
Bezüglich des Problems der Diagnostizierbarkeit impliziter Biases zeigt sich in der Literatur, dass die Organisationskultur die ...

Experimental analyses of individual sustainable choices
(2023)
This dissertation complements the aforementioned studies by considering choice and allocation experiments which allow to directly examine how individuals choose between sustainable prod-ucts and their conventional counterparts. It particularly examines how different experimental designs and interventions causally affect choices between sustainable electricity contracts and investments over their conventional counterparts and provides guidance on how to analyze these choices using a Monte Carlo experiment.

Using Optical Satellite Imagery to Monitor and Understand Agricultural Land-cover Change
(2020-06)
The activities of humans have transformed the earth over the last decades. The transformation is estimated to increase further in response to the growing world population. This has caused many countries to devise means to utilize resources sustainably. Bio-economy is seen as a means to reduce the high reliance on fossil materials and ensure the provision of raw materials, energy and food to the increasing world population in a sustainable manner. However, the rising demands for biomass to produce bioenergy have relied ...

The effect of physical activity on motor cognition in elderly people
(2021-12)
For the presented doctoral thesis, four cross-sectional studies and a longitudinal study were conducted to examine the correspondence between physical activity and motor cognition in older adults. A total of six hypotheses were tested. Forty older adults between 65 and 80 years of age (subdivided into an active and an inactive subgroup based on Freiburg Physical Activity Questionnaire) and 20 sports students as a control group participated in the cross-sectional studies. Eighty-two seniors aged between 65 and 80 years ...

Formal Verification for ALICA Plans
(2021)
Mit der Entwicklung von Wissenschaft und Technik steigen auch die Fähigkeiten autonomer Roboter. Immer mehr und kompliziertere Roboterszenarien werden in vielen Bereichen realisierbar, wie z. B. Mäh-, Ernte- und Lagerroboter. Daher wird die Planung für sie zu einer immer wichtigeren Aufgabe. Da diese Roboter jedoch täglich komplexer werden, ist die Sicherheitszertifizierung ein unvermeidliches Anliegen bei der Entwicklung von mehr autonomen Robotern. Daher ist die Verifizierung der Pläne vor der Verwendung und dem ...

Three-dimensional hydrodynamic and ecosystem modeling of warm-monomictic reservoirs (Maroon and Abolabbas, Iran) under the impact of 21st century climate change
(2021-11)
Lakes and reservoirs, as the endpoint of their upstream catchment, collect their water as the resultant of the hydrological and ecosystem processes and, thus, act as a gauge of their catchment’s management. Physical processes, e.g. stratification and mixing and propagation of density currents, are the main drivers of the biochemical factors in lakes and reservoirs and are prone to be altered and affected by climate change. Hydrodynamic models are the tools to simulate the behavior of the water body under various ...
