Stakeholder management in sustainable supply chains
(2022-03)
This dissertation examines stakeholder management in the context of sustainable supply chain management. Since ecological deterioration and social discrepancy keep increasing, sustainability is considered one of the most significant challenges in our current time. Due to the growing public awareness of the environmental and social sustainability issues, multiple stakeholders drive the need to implement sustainability into SCs and hold the focal firms responsible for the actions of the entire SC. Stakeholder management ...

The Implications of Feedback Frequency for Employee Creativity
(2022)
Managers are still floundering when they have to decide on the optimal level of feedback frequency; either when they consider themselves as a source of feedback, but also when they shape the feedback environment of their employees, e.g., by allowing more (or less) frequent customer feedback. Furthermore, given that feedback is a time-consuming task, managers might be reluctant to provide feedback frequently, foregoing a potentially powerful lever for increasing employee creativity. Ultimately, clarifying the ambiguities ...

Individual climate mitigation in the energy sector
(2021)
Based on micro-econometric analyses of survey data, this thesis extends existing research on the determinants of climate-friendly behavior in the energy sector with a special focus on economic preferences and social identity. It contains an overarching introduction and conclusion including a discussion of the policy implications of the results and avenues for future research. The main body of the thesis contains six research articles, organized in two subsections containing three articles each. All six research ...

Assessment of the variation of marbling and intramuscular fat content of beef, and validation of possible factors to increase sensory beef quality
(2021-11)
This thesis focuses on the intramuscular fat content (IMF) or the marbling of beef as main parameters of sensory beef quality. The aim is to identify the high variability of these traits and to verify possible influences such as genetics, age, gender and feeding strategies to increase marbling.
The first part of this research focuses on the variation of quality traits within a genetically homogeneous line of an endangered German beef cattle breed “Rotes Höhenvieh” (RHV). The intramuscular fat content of beef samples ...

Exploring risk and sustainability performance in base of the pyramid supply chains
(2022-07)
In the contemporary business world, the real competition is not among individual businesses but rather between supply chains. Companies, which are part of efficient supply chains, are considered destined to outperform their competitors being part of inefficient supply chains. Moreover, performance has been a matter of concern for researchers for decades and is the primary aim of any firm’s existence. The definition of performance includes the performance measurement (PM) concept and further supports the notion that ...

Sustainability of traditional cocoa agroforests in Ghana
(2022)
Cocoa (Theobroma cacao L.) is an important agricultural commodity that is important to the economies of many countries in the world. Due to cocoa’s dependence on fertile forests soils, its production is a major cause of deforestation and soil degradation in producing countries. When grown in agroforestry systems it can conserve biodiversity, sequester carbon (C), and maintain soil fertility. There are many cocoa agroforests which are managed without synthetic agrochemicals. Because organic cocoa certification is now ...

Risk management and sustainability performance in circular supply chains
(2022-09)
This dissertation analyzes supply chain risk management (SCRM) and sustainability performance in the context of circular supply chains (CSCs). The implementation of circular economy (CE) thinking in firms and supply chains has a crucial role in fostering innovative and efficient ways of producing and consuming. However, CE implementation is not a straightforward process, begetting risks and uncertainties that can impact the overall sustainability performance of CSCs. Therefore, managers need to adopt appropriate ...

Neo-institutionalism and business sustainability in emerging economies
(2022)
This dissertation deals with the institutional environment surrounding the private sector in the various emerging markets and developing economies (EMDEs) worldwide where most of the global population lives. Its primary purpose is to identify and combine theoretical aspects of new (sociological) institutionalism/neo-institutionalism to better understand the role of institutional environments in shaping business impacts on sustainable development. Institutions shape the behaviour of individuals as well as entire groups ...

Darstellung, Eigenschaften und Reaktivität phosphorreicher Ferrocenophane
(2022-05)
Im Rahmen dieser Arbeit wurde ein präparativer Zugang zu phosphorreichen Ferrocenophanen entwickelt, die Substituenten mit variierenden sterischen und elektronischen Eigenschaften tra-gen und die Reaktivität dieser gegenüber Elektrophilen untersucht.
Die Reaktivitätsuntersuchungen des als Modellverbindung ausgewählten Diphospha-[2]fer-rocenophans L6a gegenüber Elektrophilen haben gezeigt, dass sowohl ein als auch beide Phos-phoratome selektiv, durch stöchiometrische Kontrolle mit Monoboran oder unterschiedlichen ...

Functional characterization of disease-associated mutations in type I cGMP-dependent protein kinase
(2022-08)
Cardiovascular diseases are the leading cause of death worldwide, and while mainly associated with behavioral risk factors, they can also be linked to genetic disorders. The cGMP-dependent protein kinase type I (PKG I) plays a pivotal role in the homeostasis of the vasculature by mediating NO/cGMP-dependent relaxation of vascular smooth muscle cells. A recently described genetic risk factor associated with PKG I results in heritable thoracic aortic aneurysms and dissections (TAAD). Although PKG isoforms Iα and Iβ ...
