Die überdurchschnittlich hohe Akzeptanz von Frauen für Studiengänge der Veranstaltungsbranche
Das ausgewiesene Ziel der vorliegenden Masterthesis ist die Formulierung eines möglichen, multiperspektivischen Erklärungsansatzes für die überdurchschnittlich hohe Akzeptanz von Frauen für Studiengänge der Veranstaltungswirtschaft. Das Resultat besteht in der Beantwortung der Hauptforschungsfrage: „Welche evidenten Gründe sind ausschlaggebend, dass sich mehr Frauen als Männer für ein duales Studium der Vertiefung ‚Betriebswirtschaftslehre – Messe-, Kongress- und Eventmanagement‘ an der Dualen Hochschule Baden-Württemberg Ravensburg entscheiden bzw. entschieden haben?“ Hierfür wurde die Strategie der Triangulation mit unterschiedlichen Methoden gewählt. Nach der Sekundärdatenrecherche wurden unabhängig voneinander qualitative Tiefeninterviews und eine standardisierte Online-Befragung mit direkter Fragestellung durchgeführt. Im Anschluss daran wurden die Einzelergebnisse als möglicher Erklärungsansatz zusammengefasst und interpretiert. Die Erkenntnisse zeigen, dass die Studienfachwahl eine Vielzahl unterschiedlicher Einflussfaktoren vorweist: Neben begrenzt rationalen Aspekten spielen die individuelle Persönlichkeit sowie die Interessen eine bedeutende Rolle. Des Weiteren könnte die Interaktion biologischer und soziokultureller Faktoren die Geschlechterverteilung erklären.The stated aim of this master's thesis is to formulate a possible, multi-perspective explanatory approach for the above-average acceptance of women for courses of study in event management. The result consists in answering the main research question: "Which evident reasons are crucial that more women than men decide or have decided for a dual study of the specialization 'Business Administration – Trade Fair, Congress and Event Management' at the Baden-Wuerttemberg Cooperative State University Ravensburg?" For this purpose, the strategy of triangulation with different methods was chosen. After secondary data research, qualitative in-depth interviews and a standardized online survey with direct questioning were conducted independently. Subsequently, the individual results were summarized and interpreted as a possible explanatory approach. The findings show that the choice of field of study is influenced by a large number of different factors: Besides boundedly rational aspects, individual personal-ity as well as interests play a significant role. Furthermore, the interaction of biological and sociocultural factors could explain gender distribution

Distributed ledger technology in the circular economy
Lack of transparency and traceability of products and their raw materials means that most products can only be thrown away or not properly recycled due to a lack of relevant data. This conflicts with the circular economy principles, which are demanded by several initiatives, including the European Union. The aim of this master thesis is to analyze this conflict and to propose a technical solution based on Distributed Ledger Technology that enables transparency and traceability of products and their materials. Therefore, the thesis addresses two central research questions: 1. How can traceability and transparency be enabled by integrating a DLT solution? 2. How would a prototype with the integration of smart contracts and DLT look like? To answer these questions, a blockchain solution is implemented using Hyperledger Fabric. The solution uses the immutability and decentralized nature of DLT to record and track the movement of products and their materials throughout their life cycle in the Circular Economy. Furthermore, with private data collections, confidentiality, and privacy are granted while ensuring transparency. The thesis contributes to the Circular Economy field by exploring the principles, models, and challenges of the Circular Economy and the circularity goals of a Digital Product Passport to develop a suitable technical solution. The chosen blockchain framework, Hyperledger Fabric, is presented, and its key components and features are highlighted. The thesis also delves into the design decisions and considerations behind the Digital Product Passport platform, explaining the architecture and transaction flow together with the prototype implementation and demonstration to showcase the functionality of the solution. Results and analysis provide insights into the challenges of the Circular Economy, sustainable resource management, and the Digital Product Passport, resulting in recommendations for future improvements and enhancements. Overall, this thesis offers a practical solution utilizing DLT to enable transparency and traceability in the Circular Economy, contributing to the realization of sustainable and efficient resource management practices to ultimately contribute to the set Circular Economy initiatives
Chancen und Risiken der internen Rekrutierung
Die Gewinnung von motivierten und qualifizierten Mitarbeitenden stellt aufgrund verschiedenster aktueller Einflussfaktoren wie demografische Veränderungen oder der Fachkräftemangel eine große Herausforderung für das Recruiting dar. Eine umso wichtigere Rolle spielt daher die Bindung des Personals ans Unternehmen. Die interne Rekrutierung bietet in diesem Zusammenhang eine Möglichkeit, die im Unternehmen bereits vorhandenen Ressourcen zu nutzen, wobei sich im Vergleich zur externen Personalbeschaffung Chancen wie auch Risiken ergeben. Es haben sich kritische Erfolgsfaktoren gezeigt, die erkannt und in weiterer Folge berücksichtigt werden sollten. Diese sind für das Vorgehen beim internen Recruiting von Bedeutung, um möglichst das volle Potenzial ausschöpfen zu können. Im Rahmen dieser Masterarbeit wurde eine ausführliche Literaturrecherche durchgeführt, sodass in weiterer Folge eine Forschungsfrage abgeleitet werden konnte. Es wurden sieben Interviews mit ausgewählten HR-Expertinnen und HR-Experten geführt, die in Unternehmen arbeiten, die der Vorarlberger Industrie zugehörig sind. Anschließend wurden die Interviews nach der qualitativen Inhaltsanalyse ausgewertet. Im Zuge der Diskussion wurden die Interviewergebnisse der Literaturrecherche gegenübergestellt, wobei die Forschungsfrage beantwortet werden konnte. Schlussendlich wurden Handlungsimplikationen für das interne Recruiting abgleitet. Die Forschungsergebnisse deuten darauf hin, dass es im Hinblick auf die interne Rekrutierung verschiedene Erfolgsfaktoren gibt, die Unternehmen für das eigene Vorgehen berücksichtigen können. Dazu zählen beispielsweise die Bedeutung der Kommunikation während des gesamten Prozesses – Kündigungsfristen und Übergabeprozesse sollten ausreichend besprochen und umfassend geplant werden. Zudem ist es hilfreich, interne Absagen mit Bedacht auszusprechen und sachliche Gründe aufzuzeigen. Auch die involvierten Führungskräfte spielen im gesamten internen Personalbeschaffungsprozess eine bedeutende Rolle. Darüber hinaus haben sich weitere Aspekte gezeigt, die für das Vorgehen beim internen Recruiting von Bedeutung sind.Attracting motivated and qualified employees is a major challenge for recruiting due to a wide range of current influencing factors such as demographic changes or skills shortage. Therefore, the retention of employees plays an even more important role. In this context, internal recruiting offers an opportunity to make use of the resources already available within the company, whereby opportunities as well as risks arise in comparison to external recruiting. Critical success factors have emerged that should be recognized and subsequently considered. These are of importance for the procedure of internal recruiting in order to be able to exploit the full potential as far as possible. Within the scope of this master thesis, an extensive literature research was conducted so that one research question could be derived. Seven interviews were conducted with selected HR-experts working in companies belonging to the Vorarlberg industry. Subsequently, the interviews were analyzed according to qualitative content analysis. In the course of the discussion, the interview results were compared with the literature research, whereby the research question could be answered. Finally, implications for internal recruiting were derived. The research results indicate there are various success factors with regard to internal recruiting that companies can consider for their own approach. These include, for example, the importance of communication throughout the process - notice periods and handover processes should be adequately discussed and comprehensively planned. In addition, it is helpful to issue internal cancellations with caution and to point out factual reasons. The managers involved also play a significant role in the entire internal recruitment process. In addition, other aspects have been shown to be important in the approach to internal recruiting
Organizational drivers of effective crisis management
The control measures for the COVID-19 pandemic, early 2020, caused a chain reaction that eventually led to a shortage of components in the electronic manufacturing industry. A lack of components meant that the production and sales were interrupted or even stopped. For many electronic manufacturing firms, this was seen as a crisis. A crisis is mostly divided into three phases called the pre-crisis phase, crisis management and post-crisis phase. The pre-crisis phase involves an environmental assessment and setting up of crisis management teams, and plan. The crisis management phase has to do with the collection and interpretation of information and the mitigation of the crisis. The post-crisis phase looks at learnings from the crisis. In this paper it was investigated how the electronic manufacturing firms in Vorarlberg managed the crisis in the period between 2020 and 2022. The overall aim was to get a full understanding of how it affected the operations regarding the respective crisis teams and which factors were considered most important for setting up the teams. Two basic criteria which had to be over-come was the uncertainty and lack of time. It was seen that even though the fundamental structure did not change, crisis teams were added in the form of a crisis management team and task forces. The task forces played a major role in getting an understanding of the problem and the effect it has on the business. The crisis management team, which includes high level managers from all affected functional areas, had to re-evaluate the high level strategy and decide what needs to be done, and who will be doing it. In order to do so, they needed to understand what the priorities are regarding components and products and then decide on the priorities regarding affected business. The new strategy was then handed down to the task forces for implementation. A major focus of this paper was also on decision making and how everything contributed to making decisions that had the right effect in resolving the financial crisis for the organizations
Adaptive and dynamic scheduling for robust production planning
Creating a schedule to perform certain actions in a realworld environment typically involves multiple types of uncertainties. To create a plan which is robust towards uncertainties, it must stay flexible while attempting to be reliable and as close to optimal as possible. A plan is reliable if an adjustment to accommodate for a new requirement causes only a few disruptions. The system needs to be able to adapt to the schedule if unforeseen circumstances make planned actions impossible, or if an unlikely event would enable the system to follow a better path. To handle uncertainties, the used methods need to be dynamic and adaptive. The planning algorithms must be able to re-schedule planned actions and need to adapt the previously created plan to accommodate new requirements without causing critical disruptions to other required actions
Effect of visual presentation of atherosclerotic carotid plaque on adherence to secondary preventive therapy using mHealth technologies (PreventiPlaque app)
Background: Cardiovascular disease is the major cause of death worldwide. Although knowledge regarding diagnosing and treating cardiovascular disease has increased dramatically, secondary prevention remains insufficiently implemented due to failure among affected individuals to adhere to guideline recommendations. This has continued to lead to high morbidity and mortality rates. Involving patients in their healthcare and facilitating their active roles in their chronic disease management is an opportunity to meet the needs of the increasing number of cardio-vascular patients. However, simple recall of advice regarding a more preventive lifestyle does not affect sustainable behavioral lifestyle changes. We investigate the effect of plaque visualization combined with low-threshold daily lifestyle tasks using the smartphone app PreventiPlaque to evaluate change in cardiovascular risk profile. Methods: and study design: This randomized, controlled clinical trial includes 240 participants with ultrasound evidence of atherosclerotic plaque in one or both carotid arteries, defined as focal thickening of the vessel wall measuring 50% more than the regular vessel wall. A criterion for participation is access to a smartphone suitable for app usage. The participants are randomly assigned to an intervention or a control group. While both groups receive the standard of care, the intervention group has additional access to the PreventiPlaque app during the 12-month follow-up. The app includes daily tasks that promote a healthier lifestyle in the areas of smoking cessation, medication adherence, physical activity, and diet. The impact of plaque visualization and app use on the change in cardiovascular risk profile is assessed by SCORE2. Feasibility and effectiveness of the PreventiPlaque app are evaluated using standardized and validated measures for patient feedback
Systematic model selection for grey box modeling of HVAC systems
Grey Box models provide an important approach for control analysis in the Heating, Ventilation and Air Conditioning (HVAC) sector. Grey Box models consist of physical models where parameters are estimated from data. Due to the vast amount of component models that can be found in literature, the question arises, which component models perform best on a given system or dataset? This question is investigated systematically using a test case system with real operational data. The test case system consists of a HVAC system containing an energy recovery unit (ER), a heating coil (HC) and a cooling coil (CC). For each component, several suitable model variants from the literature are adapted appropriately and implemented. Four model variants are implemented for the ER and five model variants each for the HC and CC. Further, three global optimization algorithms and four local optimization algorithms to solve the nonlinear least squares system identification are implemented, leading to a total of 700 combinations. The comparison of all variants shows that the global optimization algorithms do not provide significantly better solutions. Their runtimes are significantly higher. Analysis of the models shows a dependency of the model accuracy on the number of total parameters
