TY - THES A1 - Trost, Jan T1 - How to evaluate the financial performance of soccer clubs N2 - Professional soccer is the most popular sport in the world with growing social and eco-nomic importance. It has constructed its own sector and is a continuously enlarging economy, making it mandatory for the stakeholders in this industry to be able to evalu-ate the financial performance of soccer clubs. This thesis aims to detect how the finan-cial performance of soccer clubs can be evaluated. For this purpose, multicriteria deci-sion analysis (MCDA) methods and industry-specific factors are used to evaluate the financial performance of ten of the biggest soccer clubs in Europe for the seasons end-ing 2018, 2019, and 2020. To be precise, five different MCDA methods are used as well as a Performance Assessment Model (PAM), which includes sporting performance indicators into the calculation. Furthermore, the correlation between financial and sport-ing performance is being examined. The results show that the use of a multitude of MCDA methods, while also considering sporting performance indicators next to finan-cial ratios, is the best way to evaluate the financial performance of soccer clubs. Addi-tionally, there are other non-financial indicators influencing the financial performance of a soccer club that have to be taken into consideration as well. There is no statistically significant correlation between financial and sporting performance, but they influence each other indirectly due to a club’s strategies and objectives.

Similarly, long-term player retention tied to these factors in educational or serious games are often ignored, leading to a lack of engagement and thus an ineffective product. This thesis outlines several proven design patterns employed in the entertainment-based games industry, particularly in action games. It then discusses how these patterns may be applied in digital learning environments and provides examples using a practically implemented prototype of a game combining 2D platforming, multiplayer interactivity, and vocabulary quizzes. The theoretical concepts described herein are based on peer-reviewed scientific research as well as informal resources such as presentations from the annual Game Developers Conference, development logs, or interviews with prominent figures in the games industry. They incorporate principles of visual, audio, gameplay, and didactic design; coding practices and software architecture are not discussed. The prototypical implementation employs the freely accessible Unity game engine, along with a combination of foreign and custom-made assets.

Die Relevanz der Informationsquelle und somit auch die Eigenschaften der Quelle werden seit der verstärkten medialen Informationsverbreitung während der Coronapandemie deutlich. Somit soll der Einfluss von Expertise, Reputation und Geschlecht der Quelle auf ihre wahrgenommene Glaubwürdigkeit sowie der Einfluss des Alters der Rezipierenden untersucht werden. Mittels Online-Fragebogen wurden den Befragten manipulierte Personenbeschreibungen und −aussagen präsentiert, um den Einfluss der Faktoren auf die Glaubwürdigkeit zu untersuchen. Die Auswertung ergab einen signifikant positiven Einfluss von Expertise und Reputation auf die wahrgenommene Glaubwürdigkeit der Quelle. Darüber hinaus wurde kein Einfluss des Alters der Befragten auf diesen Zusammenhang festgestellt. Es besteht kein signifikanter Unterschied zwischen der Glaubwürdigkeitsbeurteilung von männlichen und weiblichen Quellen. Die Arbeit zeigt außerdem auf, dass medial vertretene Expert:innen mit schlechtem Ruf über höhere Glaubwürdigkeit verfügen als Nicht-Expert:innen. Diese Erkenntnisse sind besonders relevant für den medialen Einsatz von Expert:innen bspw. innerhalb der persuasiven Kommunikation und der medialen Informationsvermittlung.

Germany has experienced a temperature increase of about 1.7 °C over 136 years (1881-2017) and the beginning of flowering date has advanced by about 17 days on average. In China, the temperature has increased by about 2 °C over 45 years (1963-2008), and the beginning of flowering date has advanced by about 9 days on average. Due to the large differences in the amount of data and recording time between the two countries, it is not possible to concretely conclude whether plants begin to flower is more sensitive to temperature changes in Germany or in China. However, it can still be concluded that temperature is an important factor in determining flowering time. In general, phenology is a very suitable tool for the study of effects of climate change, and climate change can also lead to a more detailed study of phenology. Overall, after evaluating the slopes of the same species in China and Germany, there was a surprising similarity of the slopes. And that it is surprising as well that all reliable datasets showed a tendency towards a shift of flowering in spring to an earlier DOY.

N2 - In der vorliegenden Arbeit soll der Einfluss von geschlechtergerechter Sprache am Anwendungsbeispiel Unternehmertum untersucht werden, welches stereotypisch männlich geprägt und männlich dominiert ist. Dabei wird der Frage nachgegangen, welchen Einfluss geschlechtergerechte Sprache in Stellenanzeigen auf die die selbstzugeschriebene Passung zu, das Interesse an und die Bewerbungsabsicht von Studierenden für ein Workshop-Programm zum Thema Unternehmertum hat. Dazu wird ein Online-Experiment konzipiert, an dem 172 Studierende teilnahmen. Es fungierten die drei geschlechtsbezogenen Sprachformen generisches Maskulin, feminin-maskuline Wortpaare und Gendersternchen als experimentelle Bedingungen. Die selbstzugeschriebene Passung, das Interesse am Programm und die Bewerbungsabsicht werden mittels validierter Skalen erhoben. Des Weiteren wird das Geschlecht ex-post-facto erfasst. Zur Untersuchung des Einflusses der geschlechtsbezogenen Sprachformen auf die drei abhängigen Variablen wurden einfaktorielle ANOVAs durchgeführt. Die Annahme, dass das Geschlecht diesen Einfluss moderiert, wurde mittels zweifaktorieller ANOVAs überprüft. Zudem wurde eine Mediationsanalyse gerechnet, um einen mediierenden Effekt der selbstzugeschriebenen Passung und des Interesses an dem Programm auf den Einfluss der geschlechtsbezogenen Sprachform auf die Bewerbungsabsicht zu überprüfen. Die Ergebnisse zeigen, dass die geschlechtsbezogene Sprachform die selbstzugeschriebene Passung und das Interesse am Programm insofern beeinflusst, dass das generische Maskulin zu signifikant niedrigeren Werten als das Gendersternchen führt. Auch für die Mediation konnte Bestätigung gefunden werden, nicht aber für die anderen Annahmen. Die Befunde bestätigen nur zum Teil den aktuellen Forschungsstand und legen nahe, geschlechtergerechte Sprache in Form von Gendersternchen in Anzeigen zur Anwerbung von Studierenden für Workshop-Programme zum Unternehmertum zu verwenden. Die Ergebnisse geben aber auch Anlass zu weiterer Forschung, insbesondere mit größeren und geschlechtlich gleichverteilten Gruppen.

UXD and SD have a lot of similarities. This has led to confusion around the borders and overlaps of both fields. Therefore researchers called for more studies to clarify their relationship. Most recent studies suggested diverting from polishing single touchpoints; some studies and focussing on end-to-end journey and the customer. The thesis examines the underlying activities of existing theoretical approaches and the challenges of combining UXD and SD with the help of thematic analysis. A set of proposed strategies were developed based on a survey on current practices and challenges with practitioners and thematic analysis. As a result, the thesis presents four strategies that design teams can incorporate into their processes. The idea is to promote the creation of better quality products and services by harnessing the benefits of both fields. The key point was that these concepts are still broad and should be simplified into leaner modes that can be applied in daily activities.

Agile and scrum-based software engineering procedures leverage software testing and quality management to find, repair, and prevent functional faults. Taxonomies help programmers see patterns and solve comparable challenges. Usability engineering-based taxonomies emphasize the use of HCD approaches to discover and classify usability concerns across the software development life cycle. Software and usability engineering have pros and cons. This thesis presents a hybrid software challenge taxonomy to bridge these two areas. The research project aims to build a new hybrid error classification system for identifying and correcting software errors at their source, leading to more user-centric software. Software engineering taxonomies and design issues are investigated. The weaknesses of any research taxonomy are then evaluated against one that fits some of this thesis' needs. User interviews and contextual inquiry are used to uncover software faults. The results of the study showed that poor usability, a mediocre user interface, workflow issues, and poor user experience caused most non-technical problems. Non-functional faults may have created many technical challenges. Six out of ten company professionals who participated in a questionnaire and interview mistook "usability" for "user experience." Usability and user experience were valued by two out of ten specialists, but they were misunderstood, expensive, and time-consuming premium approaches, and thus not included in the software development lifecycle. Ignoring non-functional issues may have caused numerous software failures. Scrum and agile used alone may also be to blame for many of the software issues uncovered in this thesis project.

Methodically, this paper provides a qualitative analysis, demonstrating theoretical and empirical findings in motivational methodologies and quality management. Motivation is a term that reduces itself into a diversifiable definition but is mostly associated to an individual’s behavior to achieve goals. Work motivation theories follow different theories to explain the individual’s behavior. These theories generate ideas to increase company performance, create goal-achievement, and can be achieved by managers mostly with extrinsic facets. On the other hand, within the DIN EN ISO 9001:2015 quality management system, work quality is divided into four focus areas: process orientation, management with motivational aspects, employee-, and customer satisfaction. Including, DIN EN ISO 9001:2015 is model oriented on a personal management basis. On behalf of the increasing employee-focus in DIN EN ISO 9001:2015, the German Society for Quality (Deutsche Gesellschaft für Qualität) proposes a New-Work model that emphasizes intrinsic motivation in the updated quality management process of DIN EN ISO 9001:2015. As a result of these theoretical findings, this thesis creates its own self-developed problem-based schematic representation of the elements of a single process in DIN EN ISO 9001:2015. Hereby, the current issues of quality management and motivation such as lack of quality awareness or limited motivation impulses in companies using DIN EN ISO 9001:2015 are emphasized and improved in the problem- based model. Quality management and motivation are progressively englobed as one factor in the current and future managerial models, which reinforces the importance of finding a problem-oriented solution.

In manchen Lebensphasen werden vermehrt soziale Kontakte geknüpft. Ein solcher Abschnitt ist oft der Beginn eines Studiums. Hier vergrößert sich in der Regel das soziale Netzwerk. Wie viele neue Beziehungen aufgenommen werden, wird unter anderem von der Persönlichkeit der jeweiligen Person bestimmt. Um den Einfluss von sozialer Neugier auf die Größe von sozialen Netzwerken zu überprüfen, wurden die Daten der Network Evaluation for Academic Retention - Studie ausgewertet. Die Studie erhebt unter anderem Daten zur Persönlichkeit und über egozentrierte Netzwerke von Erstsemesterstudierenden. Die Befragung erfolgt über einen Zeitraum von sechs Monaten zu drei konkreten Messzeitpunkten. Der Einfluss von sozialer Neugier auf die Größe des gesamten sozialen Netzwerks und des nicht-familiären Netzwerks wurde mithilfe von multiplen Regressionsanalysen untersucht (N = 93). Es konnte kein signifikanter Zusammenhang gefunden werden. Auch die Analyse des Effekts der sozialen Neugier auf die Veränderung der Netzwerkgröße über sechs Monate ergab keine signifikanten Ergebnisse (n = 55). Bei den Analysen wurden auch andere Persönlichkeitsvariablen betrachtet, die in der Forschung bereits signifikante Zusammenhänge mit der Größe von sozialen Netzwerken aufgewiesen haben. In der verwendeten Stichprobe konnten diese Zusammenhänge nicht verifiziert werden. Die Gründe für diesen Unterschied werden diskutiert. Die Untersuchung bietet einen ersten Einblick in den Zusammenhang von sozialer Neugier und der Größe von sozialen Netzwerken, welcher in der Zukunft weiter erforscht werden sollte. N2 - The building and preservation of relationships takes place throughout one’s whole life. During some life stages socialization happens more frequently than in others. One of those times is the start of academic studies, where the size of the social network usually increases. Among other things the personality of the respective person has influence on the number of relationships that are newly integrated. To examine the influence of social curiosity on the size of social networks, data from the study “Network Evaluation for Academic Retention“ has been used. It includes amongst others the data of personality traits and egocentric networks of first-year students and resulted from three surveys over a period of six months. The impact of social curiosity on the size of the entire and of the non-familial social network has been examined by means of multiple regression analysis (N = 93). No significant connection could be found. The same applies for the impact of social curiosity on the change of network size after six months (n = 55). There was also no significant result. The analysis includes other variables regarding the personality, as well, which have been proven to have an impact on the size of social networks by applied research already. Those known connections could not be found in the used sample. Reasons for that discrepancy will be discussed. This study offers a first impression of the correlation between social curiosity and the size of social networks and this topic should be examined further in future.

The purpose of this research is to understand the core factors that significantly influence the adoption of blockchain transparency and traceability in supply chain management. A qualitative research design using in-depth semi-structured interviews as the research instrument was conducted with four selected experts working in organizations (Telos, Minespider, Circular Tree, StaTwig) that provide blockchain technology solutions located in USA, Germany, and India. The findings of this study emphasized on the importance of blockchain technology, its adoption and implementation and the factors regulating its adoption. Moreover, many challenging factors that are marring the adoption of blockchain technology by the organizations were deliberated, even though these are highly advantageous. It was found that blockchain technology filled gaps over the current ERP systems and can be considered as the technology of the future. This study will be helpful for the organizations that are blockchain providers, for the organizations who are being reluctant to adopt this technology, as well as for policy makers across the world as this study provides a sneak peek into the emerging issues that these providers face.

Most research on human services workers has been focused on the topic related to mental “un-well being” such as exhaustion and burnout, instead mental “well-being”. However, lately a more positive approach of work engagement was introduced as a form of positive psychology. Since previous studies of work engagement have focused mainly on its environmental factors, this study attempted to explore the construct from another perspective which is the personality differences (extraversion and neuroticism). The main objective is to answer the question of why some individuals are more engaged than others while working in the same conditions. Moreover, the moderating effect of perceived coworker support as a form of social support is also examined in the model. A total of 246 nurses and caregivers working in Germany participated in an online survey. Findings show that extraversion and neuroticism are significant predictors of work engagement which indicates that extraverted workers are more engaged compared to the ones with high level of neuroticism. Coworker emotional support was found to buffer the negative effect of neuroticism on work engagement. However, there is no evidence of a moderating effect from coworker instrumental support on the relationship between personality traits and work engagement. The result of this study can be useful particularly for practitioners who may benefit from designing training programs that foster helping behavior among workers hence improving their work engagement.

Es lassen sich zahlreiche theoretische Studien finden, bei denen die Auswirkungen und die Effektivität narzisstischer Führung in Organisationen untersucht werden. Auf Grundlage einer systematischen Literaturrecherche werden zunächst positive und negative Auswirkungen von Narzissmus auf Führungskräfte zusammengetragen und anschließend relevante Faktoren von kontraproduktivem Verhalten von narzisstischer Führung identifiziert. Die Ergebnisse zeigen, dass narzisstische Führungskräfte zu positiven Eigenschaften wie einer charmanten inspirierenden Art, positiver Selbsteinschätzung, Erfolg in der Karriere und Überzeugungskraft neigen (Back et al., 2010; Brunell et al., 2008; Campbell et al., 2004; Maccoby, 2004; Spurk et al., 2016). Zudem stellen sich negativen Eigenschaften wie einem übermäßigen Selbstvertrauen, einer kritischen Entscheidungsfindung, einem ausgeprägten Kontroll- und Machtbedürfnis, Empfindlichkeit gegenüber Kritik, mangelndem Zuhören sowie einem Mangel an Empathie heraus (Atlas & Them, 2008; Blair et al., 2008; Campbell et al., 2004; Maccoby, 2004; Rosenthal & Pittinsky, 2006). Die Eigenschaften stellen ein hohes Potenzial für kontraproduktives Verhalten im Unternehmen dar. Die Ergebnisse zeigen, dass konkrete Faktoren von CWB durch narzisstische Führung ausgelöst werden. Zu diesen Faktoren zählen unangemessenes verbales und physisches Verhalten in Form von Aggressivität und Manipulation von Mitarbeitenden sowie einzelne Faktoren der Produktionsabweichung, welche die fälschliche Nutzung von Zeit und Ressourcen und mangelhafte Arbeitsqualität beinhalten. Es wird festgestellt, dass narzisstische Führungskräfte durch ihr Verhalten insbesondere CWB in Mitarbeitenden auslösen.

Schlüsselbegriffe: Narzissmus, Führungskräfte, Kontraproduktives Verhalten, Persönliche Aggression, Produktionsabweichungen N2 - Narcissistic leadership traits are becoming more prevalent as individuals with narcissistic personality traits are increasingly making career leaps (Spurk et al., 2016). Numerous theoretical studies can be found that examine the effects and effectiveness of narcissistic leadership in organizations. Based on a systematic literature review, positive and negative effects of narcissism on leaders are first compiled and then relevant factors of counterproductive behavior of narcissistic leadership are identified. The results show that narcissistic leaders tend to have positive traits such as a charming inspiring manner, positive self-evaluation, career success and persuasiveness (Back et al., 2010; Brunell et al., 2008; Campbell et al., 2004; Maccoby, 2004; Spurk et al., 2016). In addition, negative traits such as excessive self-confidence, critical decision-making, a strong need for control and power, sensitivity to criticism, a lack of listening skills, and a lack of empathy emerge (Atlas & Them, 2008; Blair et al., 2008; Campbell et al., 2004; Maccoby, 2004; Rosenthal & Pittinsky, 2006). The characteristics represent a high potential for counterproductive behavior in the company. The results show that specific factors of CWB are triggered by narcissistic leadership. These factors include inappropriate verbal and physical behavior in the form of aggression and manipulation of employees, as well as individual factors of production deviance, which include misuse of time and resources and poor quality work. It is found that narcissistic leaders trigger CWB in employees through their behavior. Implications for further research and important suggestions for organizational practice can be derived from the results of this paper.

Arbeitsfelder transformieren und verdichten sich mit rasanter Geschwindigkeit. Parallel steigt das durchschnittliche Alter der arbeitnehmenden Population und die Arbeitszufriedenheit sinkt. Besonders betroffen sind Erwachsene gehobenen Alters. Da die Arbeitszufriedenheit als starker Prädiktor für die physische- und psychische Gesundheit der Arbeitnehmenden wirkt, ist es notwendig zu verstehen, welche Konstrukte auf die Arbeitszufriedenheit wirken. Die vorliegende Studie betrachtet daher die mediierende Wirkung der digitalen Selbstwirksamkeit auf die Beziehung zwischen Alter und Arbeitszufriedenheit. Es wurde eine online-Befragung mit 124 Arbeitnehmenden im Alter von 17-63 Jahren durchgeführt. Es wurde erwartet, dass steigendes Alter in einer negativen Beziehung zu Arbeitszufriedenheit und digitaler Selbstwirksamkeit steht. Zusätzlich wurde angenommen, dass digitale Selbstwirksamkeit positiv auf Arbeitszufriedenheit wirkt.

The purpose of this thesis is to provide information on the economic ramifications of such workplace health promotion programs in the field of physical activity to allow for data-based investment decisions of firms. Within a cost-benefit evaluation framework, this thesis identified relevant costs and benefits from practically oriented literature. While most outcomes have been found inconclusive, reductions in absenteeism might be appropriately evidenced and sufficiently tangible to allow quantification. Based on population-attributable risk and insurance data, per employee 0.38-0.58 absence days, or 47.17-71.08€ were estimated to be solely attributable to physical inactivity. Oppositely, cost magnitude depends largely on the interventions’ format, cost-effectiveness, and especially the time investment of the participant. Yet, the economic evidence is largely restricted and demands further investigation.

This research aims to develop a smart gas burning system built on reliable and secure communication channels bounded with the implemented protocol specifications. A close study of each protocol specifications as well as a bit-by-bit investigation is therefore performed, moreover, a full timing analysis of communicated data is also carried out to ensure validity and integrity of the data transmitted. It was found that logic analysis plays a very important role in constructing data frames that are accurate to the smallest time unit possible, such analysis was not possible using an old model oscilloscope, after successful construction, transmitting a predefined sequence of data successfully initiated the communication channel between all system components. With the implemented safety and security features, the system is safe to use, however, this does not make it ready for end users, this is merely a proof of concept that such system can be made smart. The results show that the microcontroller module implemented is very capable of giving the user the ability to control the system manually with attached knobs and wirelessly through the Access point server.

In line with an expansionary course, the value of the Turkish lira depreciated and price levels started rising. Therefore, this paper will focus on the impact of monetary policy on exchange rates and foreign trade in Türkiye since 2012. For this purpose, the Mundell-Fleming model is introduced, which is a short-run macroeconomic model that assesses the effects of fiscal and monetary policies under different exchange rate regimes. Aggregated macro data on different indicators, which are representing key variables, is analyzed by using descriptive analysis. The empirical results were interpreted and discussed in line with the underlying model. The main findings of the paper suggest that Turkish monetary policy had a negative impact on exchange rates and thus on trade, especially since 2017 after the change of governmental system.

Since the pandemic has forced companies to reach out to their customers through digital platforms, the marketing strategies had to be adapted. A mixed method approach is used in this thesis, combining primary sources and data from a empirical study from an online survey, to answer the research question and test four hypothesis that are related to the impact of marketing automation on the customer behavior. The study found out that while there was an increase in personalized advertisements on social media, it is unclear how much customers were influenced. However, the thesis shows that marketing automation can be an effective to for improving the relationship between customers and companies. Furthermore, social media has become very importance for the customers’ purchasing decisions. The findings help to understand the role of marketing automation in the pandemic and provides insights for companies to help adapting their marketing strategies in the future.

Due to the tremendous increase in social media brand communication during the COVID pandemic, businesses need to study the views or the response of consumers to it and understand how to fully leverage it. With the objective to understand the consumer's views toward social media brand communication during the pandemic, influencing factors of social media brand communication were first examined, and then consumers' responses towards those factors were studied. Two research questions were developed to execute the study. The thesis first relies on a literature review to assess the influencing factors of social media brand communication during Covid-19. Then the thesis, in the empirical part, applies the qualitative research method by conducting semi-structured interviews with 10 participants grouped by aged 25-34 and users of both Facebook and Instagram. The interview was conducted via ZOOM, audio recorded, transcribed, and analyzed using MAXQDA. The result showed that the influencing factors of social media brand communication were informativeness, entertainment, credibility, interactivity, and electronic word of mouth. In general situation, the brand’s product information and value-related information were the central focus of the consumers but during the covid pandemic covid related information, CSR, health-related messages in entertaining form, source expertise, high level of brand interaction and word of mouth from the trusted sources were the influencing factors of social media brand communication.

This work develops the new model of machine learning keters inaided dynamic customer journeys , which should help marimproving customer journey design to address customers' needs. Additionally, the model could be a comprehensible tool for marketing strategy formulation. In an empirical study consisting of a survey with 168 participants and a trained machine learning mod el with a dataset size of 1000 cases, this model is validated. Results show that a machine learning model can be used commercially to cluster users into personas and that a recommendation system can be built to dynamically adapt the customer journey to give each persona an individualised experience. Future research should aim at further practical validation of the correlation between user experience improvement and persona based customer journey design.

Im Zuge der Digitalisierung im Bereich der öffentlichen Verwaltung müssen bestehende Datensätze, welche nicht- oder schwer maschinenlesbar sind, über offene Schnittstellen und Datenstandards bereitgestellt werden. Schätzungsweise 80 % der erfassten Daten sind in der öffentlichen Verwaltung nicht- oder schwer maschinenlesbar. In dieser Arbeit soll geprüft werden, ob ein künstliches neuronales Netz, welches auf der ImageNet Datenbank basiert und durch weitere Beispiele trainiert worden ist, bestehende (nicht-maschinenlesbare) Datensätze in Tabellenform aus dem Bereich der Geoinformatik erkennen und in einer passenden Datei mit offenem Datenstandard (teil-)automatisiert speichern kann, um diese für den Einsatz in einer offenen urbanen Datenplattform vorzubereiten. Zudem werden Optimierungsvorschläge für eine Verbesserung des neuronalen Netzes genannt und umgesetzt. Im Laufe der Arbeit ergibt sich, dass das trainierte Modell für den praktischen Einsatz nicht ausreichend genau funktioniert, aber eine gute Basis für weitere Optimierungen liefert, etwa durch eine Vergrößerung des Trainingsdatensatzes, welche die Anforderung einer Steigerung der Rechenleistung voraussetzt.

It evaluates how the assessment of these aspects influences the willingness to pursue a life and career abroad through a review of existing literature and an online survey conducted by the author. The theoretical background draws on Push-Pull Theory to present migration motives, Neoclassical Economics and the New Economics of Labor Migration to highlight economic reasons and the evaluation of cost and benefits, and Expectancy-Value Theory and Self-Determination Theory to examine the connection of expectations and intrinsic motivations and values related to migration intentions. The data of the survey, conducted among German university students and graduates shows that the economic assessment is not a main motivator for a life abroad but a mix of socioeconomic factors can increase the willingness to go abroad. The study highlights the importance of personal reasons, especially personal growth and cultural experience as it increases the willingness among educated Germans to migrate. Professional growth particularly, if evaluated as better abroad as well as a bad assessment of the German labor market increase the willingness for international mobility. The thesis contributes to a better understanding on the dynamics behind the international mobility intentions among highly skilled individuals in Germany.

This study introduces a novel AI-based framework based on AI technology, using GANs along with Stable Diffusion models to automate comic development. This study looks at juxtaposing narrative outlining through text with automated visual generation toward an integrated system that produces adaptable comic panels with appropriate visual structure. The research methodology that the project has followed can be built on three cornerstones: advanced GAN schemes for text generation and pre-processing, followed by image synthesis through Stable Diffusion. A specially developed algorithm for speech bubbles determined the optimal placement of that text, so it would function well and maintain a semblance of beauty. By iteratively refining and tuning the model, this system was evaluated. Initial observations regarding visual coherence and narrative alignment were hopeful, but further tests using quantitative metrics-for instance, FID for images and BLEU for text, as well as broader user feedback-would be needed to validate the efficacy of the model entirely. The impediments were, however, GAN mode collapse, irregular speech-bubble layout, and inconsistent artistic styles. Further research would uncover the potential role of AI systems in easing the comic generation process for creators, educators, and designers of digital content to enhance accessibility and efficiency. This method shows promising applicability in various domains like automated narratives, customizable comics, and educational material. Further along the way, the scientists plan to improve panel storytelling, create an intuitive interface, and expand the dataset to include more artistic styles. Such enhancements could maximize the gain from automated comic conception.

Its analyzes real-world applications of AI in recruiting, performance management, talent development, and HR administration using qualitative secondary data from academic papers, industry publications, and case studies published between 2018 and 2024. To examine employee experiences, organizational issues, and ethical implications, a combined analytical approach is used, which incorporates the Technology Acceptance Model, Job Demand-Control Model, human-centered AI concepts, and the European Commission's Ethics Guidelines for Trustworthy AI. While AI can increase effectiveness, reliability, and strategic HR results, the findings highlight concerns about algorithmic bias, reduced human engagement, and risks to employee autonomy and well-being. This paper addresses the significance of organizational planning, transparency, and responsible oversight in AI implementation, highlighting that technology should supplement rather than replace human judgment. The study offers an understanding of the human-centered and ethical aspects of AI in HRM, as well as insights for organizations seeking to use AI responsibly while maintaining employee trust and engagement.

N2 - This study has evaluated the heat loss potential and energy consumption at the industrial level. Notably, heat loss on a large scale at the industrial level has been recognized as neither economically nor environmentally sustainable. Moreover, the continued use of fossil fuels (natural gas) has been reviewed as unsustainable due to their adverse effect and limited availability, posing challenges for the present and future. Heat loss is optimized at the continental production site in Villingen-Schwenningen. Heat loss through exhaust fans, which extract heat from inside the building and release it to the environment to maintain the internal temperature, has been analysed. The released heat is lost in the environment. To recover this energy loss, the integration of a plate-to-plate heat exchanger is proposed. This approach recovers the rejected heat to preheat the incoming fresh air supply, replacing the traditional heat coil operated on natural gas. Additionally, the transition of natural gas to biogas has been explored. The district heating twin pipe (DN 80) is considered for the smooth flow of thermal energy. For this project, a financial analysis of return on investment (ROI) for 10 years is conducted, the thermal energy flow rate over 2.1km, and heat loss during the transfer phase are calculated. The results have shown significant importance for the recovered energy by integration of a plate-to-plate heat exchanger; yearly, 1.2 GW of energy can be recovered, reducing the consumption of natural gas and making a complete transition towards biogas, economically and environmentally beneficial.

N2 - This thesis assesses the preparedness of LINEG, a German public water utility, for the Corporate Sustainability Reporting Directive (CSRD). It evaluates the extent to which LINEG’s EMAS-based environmental disclosures align with CSRD/ESRS and where extensions are required to meet comprehensive ESG obligations. The analysis is grounded in Stakeholder Theory and Valente’s Stage Model to connect accountability expectations with organizational sustainability maturity. Methodologically, a qualitative case study and qualitative content analysis are applied to LINEG’s EMAS statements and relevant regulatory texts, using deductive categories derived from CSRD/ESRS and SASB, complemented by inductive coding to capture LINEG-specific themes. Peer utilities are referenced to contextualise findings. Findings show a strong environmental foundation— externally validated data on energy, emissions, water, and biodiversity—indicating partial readiness for ESRS E-standards. However, material gaps remain in social and governance areas (e.g., workforce metrics, affordability and service quality indicators, stakeholder engagement processes, and board-level oversight of sustainability). Applying Valente’s model positions LINEG between Defensive and Isolated stages: largely compliancedriven, with initiatives not yet embedded across strategy and governance. The thesis proposes a roadmap to consolidate environmental disclosures into ESRS structures, conduct a double-materiality assessment, expand S and G indicators, formalise stakeholder engagement, and assign clear governance responsibilities. Limitations arise from a single-case, document-based approach and the evolving German transposition of CSRD, which may adjust timelines and specific requirements once fully enacted.

Previous research has mostly focused on short-term organizational outcomes, and there is limited evidence about the factors that enhance job satisfaction and ensure long-term performance of an organization. To fill this gap, qualitative research was conducted, and data was collected through semi-structured interviews, and the data was analyzed using MAXQDA software. The findings represent some of the factors that significantly increase job satisfaction, such as positive and supportive work environment, flexibility and autonomy at work, career growth and continuous learning opportunities, and fair compensation with meaningful recognition. The participants repeatedly highlighted these factors as a source of enhancing motivation, dedication, commitment, and employee performance. The study suggests that when organizations actively follow and implement these factors, it is more likely to increase employee satisfaction and satisfied employees improve productivity, achieve organizational goals, and increase a higher level of dedication, which ensures organizational long-term performance.

Existing research rarely examines multiple industries together or evaluates competitiveness using both time perspectives, creating a clear research gap. The research question asks how green and traditional companies differ in financial performance, innovation, consumer trust, and regulatory responsiveness. The hypothesis proposes that green companies show lower short-term competitiveness, but higher long-term competitiveness than traditional firms. A qualitative comparative case study approach is applied using secondary data, including annual reports, sustainability disclosures, ESG ratings, and international regulatory frameworks. Six companies are analysed: Tesla and Toyota in the automotive sector, Hilton and Wyndham in hospitality, and Kering and H&M in fashion. Their competitiveness is assessed through a structured framework that distinguishes between immediate business outcomes and long-term strategic development. The findings show that traditional companies perform better in the short term due to efficient cost structures, established operating models, and stable supply chains. Green companies, however, achieve stronger long-term competitiveness by investing in innovation, transparency, and alignment with tightening regulatory and consumer expectations. Tesla, Hilton, and Kering demonstrate superior long-term performance, while Toyota, Wyndham, and H&M maintain advantages mainly in the short term. The results support the hypothesis and highlight sustainability as an important driver of long-term competitiveness. The study offers cross-industry insights for academics, managers, and policymakers and identifies opportunities for future research on sustainable business models.

This thesis advances the Ball Point Pen Game into a production simulation that exposes bottlenecks, queues, work-in-process accumulation and defects while keeping the pen-assembly task simple and standardised. Using design-based research, one design-test-reflect cycle was executed: redesign requirements were derived from Lean and lean-game education literature, implemented as roles, control rules and learning objectives, and piloted in class. The revised game increases complexity without adding product difficulty by introducing an explicit order-release rhythm (takt), separated material and information flows, visual control, and progressive pull logic across three rounds. Across rounds, batch size is reduced stepwise, supermarket/Kanban replenishment is introduced, and a simple poka-yoke prevents assembly errors. A pilot execution with seven students evaluated the redesign using a single-group pre–post knowledge test, a post-game perception questionnaire, and in-game KPIs (throughput, lead time, WIP and defects) supported by observation notes. Results are interpreted as exploratory due to the small sample and lack of a control group. Participants reported high engagement and that game discussions helped translate observations into improvement actions, aligning with prior evidence that simulation games can support understanding and transfer in Lean education. However, implementation deviations required by the small group (role merging and ad-hoc facilitation changes) reduced instruction clarity for at least one participant. The thesis delivers a reusable player/instructor manual plus design rationales and measurement procedures to guide the next test and a larger evaluation with stronger internal validity.

However, they are computationally expensive to train, with approximately two-thirds of non-embedding parameters residing in Multi-Layer Perceptrons (MLPs). Liu et al. (2024) revisited the long-disregarded Kolmogorov-Arnold representation theorem and demonstrated promising results in specific domains such as symbolic regression and PDE solving. Whether Kolmogorov-Arnold Networks (KANs) generalize to other domains, particularly NLP, remains an open research question. This work systematically evaluates five architecture configurations: MLP baseline, MLP with B-Spline activation, KAN with B-Spline, KAN with Mean aggregation, and Group-Rational KAN (GR-KAN) - across three model sizes (15M, 41M, 124M parameters). Experiments are conducted on text classification (“AG News”) and language modeling (“FineWeb”) tasks. Identical components (attention, embeddings) isolate performance differences to the feed-forward topology. Statistical validity is ensured through multiple random seeds and parameter-matched comparisons. KAN-based architectures achieve performance parity with MLPs on classification tasks (±0.5 percentage points accuracy). However, they consistently underperform on language modeling, with perplexity increases of +7 to +28 points. Training efficiency overhead ranges from 1.5–2.0× for KANs, while GR-KAN approaches baseline speed. Notably, KANs exhibit significantly higher sparsity (≈ 90% vs. ≈ 40%), enabling compression factors of 1.4–1.6× with minimal performance degradation. The MLP+B-Spline control condition reveals that performance deficits stem from KAN topology rather than activation functions. KANs present a viable alternative for discriminative NLP tasks but do not outperform MLPs for generative language modeling. The postulated interpretability advantage through learnable activation functions could not be empirically confirmed - learned functions degenerate to quasi-linear transformations. Future research should explore alternative basis functions and selective hybridization strategies.

From Identifying User Needs to Assessing its Effectiveness in Reducing Anxiety and Enhancing Travel Preparedness N2 - Air travel can present significant accessibility barriers for autistic travellers. This study examined the needs, requirements, and challenges experienced by level 1 and level 2 autistic travellers during air travel and evaluated the effectiveness of a user-centred mobile application in reducing anxiety, improving their travel preparedness, and creating a more predictable air travel experience. A mixed-methods approach was employed for the study. In the beginning, an online survey with 35 participants (21 autistic individuals and 14 support persons) was conducted to understand the need, requirement and challenges of the autistic participants. Findings from the survey showed generally low satisfaction among autistic travellers who has prior air travel experience. The major challenges were related to unpredictability, sensory overstimulation, complex airport procedures, difficulty finding sensory-friendly spaces, and in-flight discomforts. Based on the insights from the survey, a high-fidelity mobile application prototype was designed to work across different airlines and airports providing real-time flight updates, airport and airline specific accessibility information, navigation support, communication cards, and travel checklists. The prototype was then evaluated with 5 autistic participants through a moderated remote usability test followed by a post-test interview and questionnaire. The results showed that features such as real-time flight updates, travel checklists, navigation support, and accessibility information were effective and perceived as helpful in reducing anxiety and increasing preparedness but some discoverability issues were identified in the prototype showing the need to iterate it. Overall, the findings suggest that the application is functionally effective and usable but only partially effective in improving overall travel experience as external environmental factors like airport procedures, in-flight discomforts are beyond the scope of the application. The study also highlights that a thoughtfully designed mobile application can partially support autistic travellers by improving the predictability and helping them prepare for the journey. This study contributes to the growing research on accessibility for autistic individuals by examining air travel challenges and evaluating a user-centred mobile application.
