Optimierung des Risikomanagements als Beitrag zur Steigerung des Projekterfolgs bei Produktentwicklungsprojekten am Beispiel der Automobilindustrie
(2024)
Die zunehmende Projektifizierung der letzten Jahrzehnte hat dazu geführt, dass der Beitrag von Projekten zur Erreichung der Unternehmensziele und damit zur unternehmerischen Wert-schöpfung in gleichem Maße gestiegen ist. Gleichzeitig sind Projekte aufgrund ihres einzigar-tigen Charakters mit Risiken und Unsicherheiten behaftet, deren Auftreten im Kontext der Produktentwicklung in der Automobilindustrie durch den Produktivitätsdruck sowie die stetig steigende Komplexität und Dynamik noch verstärkt wird. Die negativen ...

Risk Communication during the COVID-19 Pandemic
(2024)
In this PhD project it was aimed to learn about the potential and the challenges of risk communication in systemic risks by conducting applied research during the COVID-19 pandemic. Risk communication plays a crucial role in mitigating these risks by addressing risk beliefs in the population and thereby stimulating behavior change. In the synapsis of this project, however, the prevalence of heterogenous prior risk beliefs in different groups of the population were identified as a major challenge for risk communication ...

Design and Implementation of Novel Optical Fabry-Pérot Arrays for Medical Applications
(2024)
Optical sensing systems find a wide range of applications, especially in the medical field, for intelligent, patient-operated health monitoring and early diagnosis, facilitating immediate responses to warnings. Advances in technology have enabled sensors miniaturization with spectrometers using low-cost Fabry-Pérot filters, allowing integration into mobile phones and wearable devices without compromising their resolution. The challenge in filter fabrication is deforming supporting posts deformation during polymer ...

In the Face of Adversity – Conceptual and Empirical Studies on Team and Organizational Resilience
(2024)
In this cumulative dissertation, the resilience of organizational actors is explored through four independent essays. The focus is on investigating why certain organizations and teams are better equipped to handle adversities than others. At the outset of the project, a comprehensive literature review on current research in the field of organizational resilience was conducted. This review enabled the authors to identify the so-called "Building Blocks" of organizational resilience, which provide essential theoretical ...

A critical assessment of opportunities and challenges from Blockchain adoption in supply chain management
(2024)
This dissertation explores the role of blockchain technology within the domain of supply chain management. The research navigates the promising and rapidly evolving landscape of blockchain technology, marked by ongoing challenges and supply chain developments. The study comprises four distinct yet interlinked examinations, each focusing on specific aspects of blockchain application in supply chain management, encompassing traceability, transaction costs, digital freight information, and the inherent tensions in ...

Functional analyses of Dph1•Dph2 in synthesis of diphthamide, a clinically relevant modification on eEF2
(2024)
Diphthamide is a unique post-translational modification of a conserved histidine on the eukaryotic translation elongation factor 2 (eEF2). During translation elongation, eEF2 induces translocation of codon-anticodon duplexes across the ribosomal decoding center. Diphthamide is involved in fine-tuning of this process by stabilizing the codon-anticodon duplex and maintaining reading frame accuracy. Initially, diphthamide was identified as the target for diphtheria toxin, enabling ADP-ribosylation of eEF2 and resulting ...

On the Path to Professionalization in Coaching: From Coaches' Attitudes for Participating in Coaching Research to Improving Coachees' Reflective Capacity
(2024)
This dissertation aims to advance the professionalization of coaching by advancing coaching research. It does this by meeting the demand for methodological grounding and examining coaches' motives for participating in coaching research, thereby contributing to the generation of larger and more-realistic samples (Study 1), by conducting theory-driven research based on psychotherapy research, and by using an observer-based method to evaluate behavioral data (Study 2). At the same time, it contributes to improving the ...

Professionalisierungsprozesse im Lehr-Lern-Labor Sportpädagogik
(2024-03-13)
Mit der Konzeption und Einrichtung des Lehr-Lern-Labors (LLL) Sportpädagogik verfolgt der Arbeitsbereich Erziehung und Unterricht am IfSS der Universität Kassel die Zielsetzung, unterrichtsrelevante Themen an universitären und schulischen Lernorten einer pädagogischen Begründung, didaktischen Erprobung und gemein-samen Reflexion zu unterziehen. Theoretische Bezugspunkte sind zum einen die professionelle Handlungskompetenz und zum anderen die Unterrichtsqualität. Pädagogisches Handeln sollte sich auf wissenschaftliche ...

Evaluation of Bitumen-Aggregate Adhesion Bond Based on Surface Free Energy and Comparison with Moisture Sensitivity and Asphalt Performance Tests
(2024)
The adhesion bond between aggregate particles and bitumen plays a crucial role in ensuring the durability of asphalt pavement, and it is influenced by factors such as bitumen-aggregate compatibility, moisture exposure, other environmental conditions, and traffic loads. Failure of the adhesion bond results in the detachment of bitumen from the aggregate surface and leads to stripping in the presence of moisture. This, in turn, leads to the development of macro cracks and disintegration within the asphalt pavement, ...

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 ...
