Metaverse Governance: Transparency, Accountability and DAOs

In recent years, social and economic life has been augmented by myriad digital propositions ranging from social media to augmented reality online shopping and role-based multi-player gaming. A second trend, which has started with the introduction of “Second Life”, and which has gained further momentum through Facebook’s rebranding into “Meta”, is the building of immersive, persistent, three-dimensional virtual worlds – termed metaverses (Dincelli and Yayla 2022) – in which actors interact (and/or ‘live’) as digital avatars. This seminar work deals with the governance of metaverses. What frameworks exist? Do dimensions we know from corporate governance such as transparency or accountability (Brennan and Solomon 2008) hold for Metaverses? And what exactly is a DAO and how do DAO members influence community decision-making. Finally, what do we know about user acceptance of Metaverses in relation to their governance structure?

On Demand Car Functions: Strategies, Applications, and Cost Structure

Car manufacturers such as Audi or Tesla offer so-called on demand car functions as fee-based activation of pre-installed technologies to enable up-selling and to build better customer relationships. So far, however, acceptance of these services is low and car manufacturers struggle to promote these services. While some nascent research into on demand services exist, we still do not know, for example, how type of contract (leasing vs. purchase) and feature tangibility (software vs. hardware) affect psychological ownership and sustainability perceptions as drivers of purchase decisions. The goal of this seminar topic is to conduct a literature review on on-demand car features, and provide an overview of what kind of features typically exist across brands. The challenge lies in finding figures that describe the tradeoff between the benefits (i.e. standardized product) and the drawbacks (i.e. building a technology in each car no mater if needed or not). Hence, it may be required to conduct 2-3 qualitative interviews with topic experts. The expected results help to better understand consumer’s purchase intentions in individualized and customized digital marketing.

Open Source Governance: Alignment with overall IT governance or separate practice?

Open source governance is part of IT governance and focuses on the specific issues related to the acquisition, use and management of OSS, and ensuring it is done in alignment with a company's stated objectives, policies and risk profile (Bearingpoint 2013). However, in large companies, governance often depends on organizational structures and while one department might be in favor of using open source software for business purposes, others are not. The goal of this thesis is to synthesize literature on IT governance (e.g. Akbari et al. 2024) that deals with departmental structures and literature on open source governance. If possible, a (graphical) framework should be build that displays the synthesis.

Towards a definition of dynamic pricing in the era of AI

Dynamic Pricing, a concept yet to be precisely defined, represents a critical area of study within the fields of economics and information technology. This seminar paper aims to advance towards a definitive understanding of Dynamic Pricing by conducting a thorough examination of existing literature. The methodological approach involves a structured literature review, through which we seek to pinpoint and analyze various factors that play a significant role in the application and theory of Dynamic Pricing. Particular emphasis is given to the exploration of cutting-edge technologies, notably artificial intelligence (AI) and machine learning (ML), which are increasingly pivotal in the implementation and optimization of Dynamic Pricing strategies. The rationale for focusing on AI and ML technologies stems from their capability to analyze vast datasets, predict market trends, and automate pricing adjustments in real-time, thereby offering potential for more efficient and effective pricing models. Through this comprehensive analysis, the paper will contribute to the academic discourse on Dynamic Pricing, offering insights that may facilitate the development of more refined and universally accepted definitions and applications of this concept.

Digital Twin – Eine Brücke zwischen physischen und virtuellen Welten

Digital Twins werden als digitale Repräsentation eines physischen Produkts, Systems oder eines Menschen beschrieben, die das Verhalten ihres physischen Gegenparts in einer virtuellen Umgebung widerspiegeln und vorhersagen können. Digitale Zwillinge werden bereits in vielen Anwendungsbereichen eingesetzt. Zum Beispiel können Digital Twins durch die Integration von Daten über Energieverbräuche und -erzeugung verschiedener Geräte in einem intelligenten Stromnetz Dienste anbieten, die eine Optimierung der Energieflüsse ermöglichen (Olivares-Rojas et al. 2021). Des Weiteren unterstützen sie die Produktentwicklung bei der Optimierung von Recycling-Prozessen (Ren et al.2022) und die Stadtplanung bei komplexen Prozessen, wie z.B. Notfallmaßnahmen im Katastrophenfall (Fan et al. 2021). Dieser Themenkomplex beschäftigt sich mit den technologischen Eigenschaften und den Einsatzpotenzialen der Digital Twin-Technologie. Ein besonderer Fokus liegt hierbei auf der Untersuchung der Anwendung von Digital Twins an Menschen. Sogenannte Human Digital Twins und deren Potenziale für die Automatisierung menschenbezogener Entscheidungsprozesse werden bereits in unterschiedlichen Anwendungsbereichen, wie z.B. im Marketing und Gesundheitswesen, diskutiert. Im Rahmen dieses Themenkomplexes sollen die zentralen Eigenschaften und Potenziale dieser Technologie identifiziert und diskutiert werden.

Obwohl Digital Twins in den letzten Jahren in Forschung und Praxis zunehmend Aufmerksamkeit erlangt haben, gibt es bisher nur wenig Literatur, die einen Überblick über die funktionalen und technologischen Merkmale von Digital Twins bei der Anwendung am Menschen vorstellt. Human Digital Twins werden bereits in verschiedenen Anwendungsbereichen, wie z.B. im Gesundheitswesen oder im Marketing, diskutiert. Allerdings versäumt es die Literatur bislang, den Begriff Human Digital Twin zu konzeptualisieren und darauf einzugehen, inwiefern Human Digital Twins eine Erweiterung zur Digital Twin-Technologie darstellen. Eine detaillierte Auseinandersetzung mit den besonderen technischen Charakteristika von Human Digital Twins kann genutzt werden, um die Potenziale der Technologien in verschiedenen Anwendungsgebieten zu untersuchen.

Um die Lücke in der Abgrenzung zwischen Digital Twins und Human Digital Twins zu schließen, liegt der Schwerpunkt dieser Arbeit auf der Identifizierung der zentralen Eigenschaften von Human Digital Twins. Ziel der Arbeit ist, einen Überblick über die relevanten technologischen Charakteristika von Human Digital Twins zu geben. Darauf basierend soll diskutiert werden, inwiefern ein Human Digital Twin eine Erweiterung des traditionellen Digital Twin-Konzepts (z.B. angewendet auf Produkte, Systeme, Prozesse) darstellt. Dabei soll insbesondere auf die spezifischen Anforderungen an die Repräsentation eines Menschen im Vergleich zur Abbildung von nicht-lebendigen Objekten eingegangen werden. Auf Basis der identifizierten Alleinstellungsmerkmale von Human Digital Twins sollen die Potenziale der Technologie für verschiedenen Anwendungsbereiche in unterschiedlichen Domänen strukturiert diskutiert werden.

Strategic Insights: Using Data Analytics to Derive Guidelines for Recruitment Process Optimization

In the face of demographic change and the intensifying “war for talents” (Beechler & Woodward, 2009; Chambers et al., 1998), companies across the globe, and especially in economically competitive markets like Germany (Faems & Hülsbömer, 2022; Löffler & Giebe, 2021), are in a constant struggle to attract and retain top talent. The initial touchpoint in the recruitment process (sometimes referred to as application and selection practices), the application phase, plays a pivotal role in shaping a potential employee's perception of an employer. The experiences of job applicants during this phase are more than mere procedural steps; they are reflective of the company's ethos, operational efficiency, and attractiveness as an employer (Campion et al., 2019; Okolie & Irabor, 2017). Given these stakes, there is an imperative need for organizations to reevaluate and enhance their recruitment strategies. Therefore, the genesis of this seminar lies in the recognition of the application process as a pivotal element in the talent acquisition strategy. Traditional approaches to understanding and optimizing this process have often relied on internal assessments and isolated feedback mechanisms. However, the advent of employer review platforms like kununu.com has opened new avenues for gathering comprehensive and authentic insights into the applicant experience (e.g., see Schaarschmidt et al., 2021). These platforms, rich with candid reviews from both satisfied and dissatisfied job applicants (Höllig, 2021), provide a treasure trove of data that, if analyzed thoughtfully, can reveal deep insights into what constitutes a 'good' or 'bad' application process from the perspective of potential employees.

  • When selecting this seminar, students should employ qualitative or quantitative (or mixed method) content analysis approaches (e.g., topic modelling via latent Dirichlet allocation or qualitative content analysis) to derive guidelines for “optimal” recruitment processes.
  • Employer reviews (mostly in German language) from DAX40 companies are provided to the student by the supervisor.

The motivation for this seminar is twofold. First, it aims to equip participants with the ability to harness the power of data analytics to decipher the vast amounts of unstructured feedback available online. Second, it seeks to translate these insights into actionable guidelines that can significantly enhance the effectiveness of recruitment strategies, thereby positioning companies as preferred employers in a market that is becoming increasingly selective.

Generative AI for Greater Good

The advent of generative AI (GAI) technologies has opened up unprecedented opportunities for innovation across various sectors, including healthcare, education, environmental protection, and social welfare. These technologies have the potential to revolutionize how we address complex societal challenges by generating novel solutions, enhancing decision-making processes, and automating tasks to improve efficiency and accessibility. However, harnessing the power of GAI for the greater good requires careful consideration of ethical implications, inclusivity, and the potential for unintended consequences. The ongoing discourse on GAI seems to extol the promises of AI (utopian visions of a world free of drudgery and want) and the dangers (dystopian visions of machines taking over the world). The objective of this topic is to offer a careful examination of the challenges faced in managing this powerful set of technologies for individuals, organizations, and society to harness GAI for greater good. Thus, the work should discuss on GAI perspectives from individual, organizational and societal levels.

Topic range: E-commerce for social and environmental sustainability

Digital sustainability (see Kotlarsky et al. 2023) has been considered by Gartner as “tools of digital transformation, such as enhanced connectivity and the Internet of Things (IoT), to improve the environment and support sustainable business operations”.  In this seminar, you will investigate digital transformation of trading and how it shapes global societies. With the rise of the world wide web, for instance, a new form of trade emerged in the mid 1990s (e.g., Heng 2003). The Web provided a new tool to entrepreneurs who sell and buy products and services with less friction. Nowadays customers gain access to products and services from all across the globe, oftentimes without the need to leave their house. The revolution in shopping led to the significant changes in the customer’s behavior and social interactions between individuals and social groups.

In this seminar, you will have a chance to explore the world of online trade. Your goal will be to address one of the mentioned below topics based on academic literature reviews (e.g., Rowe 2014; vom Brocke et al. 2015; Shan et al. 2023). Seminar will deepen your knowledge in the area of e-commerce, sustainability, international trade and business.

  • Digital technologies can play a crucial role in addressing social issues in rural areas (Tim et al. 2021). E-commerce is a unique form of trade that allows small and medium enterprises (SMEs) to reach customers in affluent regions that were previously inaccessible due to high barriers to entry. The democratization of access to rich regions is a unique opportunity for both poorer and richer regions to benefit from the exchange of goods and services. In this assignment you will investigate the importance of e-commerce in empowering local communities. Look at the existing academic literature from the perspective of the local community member. Discuss the role of e-commerce in reducing barriers for local entrepreneurs.

    Methodology: Systematic Literature Review

    Suggested research question: How does e-commerce change the entrepreneurial habits of local communities?

Potentials and challenges of integrating digital health applications (DiGA) into existing healthcare and information systems

E-health refers to the application of information technology and electronic tools, services, and processes for application fields and use cases in healthcare. It includes a wide range of digital technologies that aim to assess, improve, maintain, promote, or modify health or health conditions through diagnostic, preventive, and therapeutic measures in somatic as well as mental health care. Application types include the use of electronic health records, telemedicine, health information systems, wearable devices, and mobile health applications such as health apps.

In Germany, since 2020, certain approved digital health applications (DiGA) can be prescribed by doctors and psychotherapists and reimbursed by statutory health insurance companies. In the care sector, there are also approved and reimbursable solutions in Germany: digital care applications (DiPA), which are specifically intended to support patients in need of care and their relatives or professional caregivers. DiPA can be prescribed by doctors in Germany and reimbursed by statutory health insurance companies as well.

E-Health can potentially increase the efficiency of patient care, reduce costs, improve the quality of healthcare, facilitate access to relevant services, support disease research and public health, and also promote active patient participation. However, there are also numerous challenges, for example, regarding data quality, long-term user adoption, privacy and security, and integration into existing systems (Milne-Ives et al., 2020).

As part of this seminar paper, a literature analysis will be conducted to determine how the integration of DiGA into existing health and information systems can create benefits and what kinds of barriers and challenges exist.

Challenges in implementing and efficiently managing electronic health records (EHRs)

Through digital innovations and enabling technologies, the importance and spread of digital ecosystems in the healthcare sector are increasing (Stephanie & Sharma 2020). Through digital health ecosystems, the roles and interactions of actors in the health sector are changing, which is increasingly transforming it and contributing significantly to the digital transformation in the health care sector (Hermes et al., 2020). Electronic health records (EHRs) are digital versions of traditional health records. They contain all of a patient's relevant medical information, including demographic data, diagnoses, tests performed, treatments, laboratory tests, and current as well as previous medications.

EHRs provide various benefits in modern healthcare as they provide an efficient, accurate, and secure method of storing and sharing patient information if they are well implemented. EHRs can be accessed by various healthcare stakeholders, promoting collaboration between all relevant stakeholders and enabling coordinated and efficient care. In this way, both the quality of patient care and the efficiency of the processes can potentially be optimized. Implementing EHRs also comes with numerous challenges, such as privacy and security. (Kohli & Tan, 2016).

The electronic patient record (ePA) was introduced in 2021 for those insured by German health insurance companies and is intended to contribute to the digital transformation of the healthcare system in Germany. EHRs promise numerous benefits for various stakeholders in the healthcare system, particularly in terms of increasing efficiency and improving patient care. However, the successful implementation of EHRs in practice depends on numerous organizational, human, and technological factors and therefore represents a challenge for healthcare stakeholders (Fennelly et al., 2020).

As part of this seminar paper, these challenges will be identified and specified using qualitative interviews with practitioners involved in medical care. Finally, approaches to solving these challenges will be discussed.

The role of big data analytics in the context of electronic health records (EHRs)

Big data analytics refers to the use of advanced analytical techniques to analyze large, complex sets of data. The analysis of big data creates numerous new opportunities to generate additional value for various players in the healthcare system, such as healthcare providers and patients (Wang et al., 2018; Kankanhalli et al., 2016). The EHR contains all of a patient’s relevant health information, including demographics, medical history, medications, laboratory tests, and other medical information. The combination of big data analytics and electronic health records can potentially help improve patient care and efficiency in several ways. Furthermore, the use of large amounts of data generated in EHRs can not only benefit health care providers at the individual level but also potentially significantly improve public health by using the data for clinical research and automated disease surveillance (Shah & Khan, 2020).

As part of this seminar paper, a literature analysis will be conducted to identify which opportunities big data analytics offer in the context of EHR/ePA to sustainably optimize efficiency and patient care and which barriers exist in this context regarding the use of big data.

Multi-Level Modeling: Motivation, Prospects, and Challenges

The benefits of conceptual models are undisputed. They foster communication between different stakeholders, contribute to reuse, integration and flexibility. However, prevalent modelling languages suffer from serious shortcomings. While domain-specific modelling languages (DSML) address some of these limitations, serious problems remain. They relate to fundamental design conflicts, the construction of modelling tools, and the synchronization of models and code. Multi-level modelling and multi-level language architectures in general constitute a new modelling paradigm that allows to substantially relax these problems. Furthermore, it enables a new kind of (enterprise) software systems that feature a high degree of flexibility and user empowerment. First, this term paper aims at describing the motivation for multi-level modelling and its characteristic properties. Second, it should analyze the potential of multi-level modelling for developing advanced DSML and powerful enterprise systems.

Teaching Meta Modeling with Multi-Level Modeling Languages and Tools: Critical Analysis of Prospects and Challenges

Two artifacts can be distinguished in conceptual modeling: the modeling language that specifies the syntax and semantics of modeling concepts and the models that are produced with this modeling language. Modeling languages are often specified through the definition of a further model – the meta model – that resides on a higher level of abstraction than the user-defined models. Meta models of widely disseminated and used modeling languages are often created and maintained by large consortia, e.g., the Unified Modeling Language (UML) that is managed by the Object Management Group (OMG). To increase the productivity and efficiency of conceptual modeling, multiple researchers call for the specification of domain-specific modeling languages (DMSLs). For this purpose, students must obtain the competency to construct high-quality meta models. This seminar paper sets out to identify learning objectives related to the construction of meta models. You should analyze how multi-level modeling (MLM) can support teaching these learning objectives and where challenges occur.
