Many companies employ management consultants to manage large and complex projects. The working relationship between counselors and their clients is still largely unexplored. Exciting questions are, for example:

• How does know-how transfer between consultant and customer take place?
• What role does personal "closeness" between consultant and customer (e.g. same degree) play in the project work?
• Which critical success factors (in the relationship between customer and consultant) increase the chances of successful project work?

Digital health technologies (websites, platforms, social networks, apps, wearables, etc.) aim to positively influence the health and well-being of consumers.

However, little is known in research about which factors influence potential eHealth users in their adoption and use of such technologies and what influence actual eHealth use has on the health and well-being of users.

Accordingly, on the basis of theoretical models and empirical studies, new insights into the adoption, use and ideally also the effects of eHealth should be gained.

An empirical study can be carried out both qualitatively (interviews with consumers) and/or quantitatively (questionnaires), with a quantitative study being preferred. The "general" population as well as special groups such as senior citizens or patients can serve as subjects.

The selection of the theoretical bases/models, research method, target group and type of eHealth technology are determined in consultation with the supervisor of the thesis.

Large organizations, such as Lufthansa Airlines, rely on the expertise and support of external providers to fulfill their duties. In order to steer the activities of the providers, a management system has to be established. Over the past decades, the structure of such systems has evolved with Service Level Agreements (SLAs) becoming an integral part of it. These SLAs are oftentimes customized to specific scenarios and lack standardization, hence, leading to increased administrative overhead.

This master thesis, in collaboration with Lufthansa Airlines, will address the following issues:

1. What is the status quo in SLA-driven provider management? (Methodology: Literature Analysis according to Webster & Watson (2002))
2. What are expectations on sound SLAs in airline provider management? How are SLAs currently utilized at Lufthansa Airlines to steer providers? (Methodology: Semi-structured expert interviews)
3. Development of a blueprint for the ground operations department by combining the learnings from (1) and (2) (Methodology TBD)

In recent years, the world of technology has witnessed a significant transformation as Information Technology (IT) and Operational Technology (OT) have started to converge. This convergence marks a fundamental shift in how organizations manage and utilize their technological infrastructure. To put it simply, IT encompasses the technologies and systems used for data processing, networking, and general computing tasks, while OT includes the specialized technologies that control and monitor physical processes, such as machinery, sensors, and industrial equipment. The convergence of IT and OT refers to the merging of these traditionally distinct domains, creating a unified ecosystem where IT systems and applications interconnect with OT technologies. IT and OT convergence holds promise for various industries, such as manufacturing, energy, healthcare, and transportation, as it allows for more seamless data sharing, increased automation, and better control over complex operational processes. However, this transformative trend also brings challenges and implications for IT management, as it blurs the boundaries between traditional IT responsibilities and those associated with OT systems. This master's thesis aims to investigate the consequences of the IT and OT convergence for IT management, focusing on the changes in roles, responsibilities, and strategies required to effectively navigate this evolving landscape.

Possible Research Objectives:

1. To investigate the specific consequences of IT and OT convergence on IT management practices, including changes in roles, responsibilities, and skillsets.
2. To assess the impact of IT and OT convergence on IT governance, cybersecurity, and risk management strategies.
3. To identify best practices and strategies for organizations to adapt their IT management frameworks to the demands of a converged IT and OT environment.

Due to demographic change, aging people are increasingly becoming the focus of society and the economy: increasing health risks, increasing social isolation, declining self-determination. Increasing digitalization is creating completely new opportunities – for example through social platforms, IT wearables and mobile applications – to achieve general well-being, social inclusion, active health care and thus a longer, self-determined life for the aging population.

However, a prerequisite for the development of this potential is that people or seniors make use of these technologies - and the actual use of these technologies by seniors often takes place only to a small extent. Older people tend to say "I'm too old for computers" - they associate their age with technology use. However, it has also been shown that people often do not "feel as old" as they actually are: subjective age and chronological age are not always consistent.

Little is known in research about the influence of this subjective assessment of one's own age on IT acceptance and use. Accordingly, in this thesis, conceptual and theoretical foundations from "aging research" are to be derived from the literature and tested on the basis of an empirical study in the context of IT acceptance. The specific design of the topic takes place in consultation.

Due to demographic change, aging people are increasingly becoming the focus of society and the economy: increasing health risks, increasing social isolation, declining self-determination. Increasing digitization creates a problem area that has so far received little attention.

For practically every piece of software, hardware, apps, etc., users have to authenticate themselves, usually by entering a PIN or password. However, the aging society has to contend with two problems: declining memory and declining motor skills. Passwords are easily forgotten, biometric recognition and entering passwords are made more difficult by trembling fingers, for example. If more and more activities are digitized, while at the same time society is getting older, we are faced with a dilemma.

Creative mechanisms are being sought for how users can authenticate themselves securely and unequivocally, taking into account the problems outlined above. In terms of research methods, a wide range of interviews and surveys about controlled experiments and the use of the usability lab at the HNU is available. This topic can therefore also be worked on independently by several students. The concrete design of the topic and the empirical procedure is determined in close consultation with the supervisor.

Congestion, noise and air pollution - urban mobility is one of the most challenging issues of the 21st century. More and more people live in cities and metropolitan areas and are dependent on a functioning transport system. In addition to public transport, e-scooter sharing services have been providing another sustainable option as an alternative to the use of private cars in cities for several years.

The thesis will first analyze user behavior in the city centers of Ulm/Neu-Ulm. For this purpose, user data from the largest e-scooter provider (TIER) in the region will be used and analyzed.  Furthermore, this user data will be compared with the route networks of public transport in order to deduce whether e-scooters are used in addition to or instead of public transport.

Within the scope of the final thesis, the following research questions are to be answered:

• What is the current state of research in the (IS) literature on e-scooter use and the impact on public transportation?
• What is the mobility behavior of e-scooter users in the city centers of Ulm/Neu-Ulm?
• How does the use of e-scooters in the city centers of Ulm/Neu-Ulm influence the use of public transport?

The thesis must be written in English. The specific topic is determined in consultation with the student.

Traffic jams, noise and air pollution - urban mobility is one of the most challenging issues of the 21st century. More and more people are living in cities and metropolitan areas and are dependent on a functioning transport system. But although the public transport network in German cities is already very well developed and the negative effects of car traffic are well known, many people still do not use sustainable means of transport in everyday life.

This thesis deals with the question of how the use of different technologies such as mobility apps and incentive mechanisms can make public transport in a city more attractive. The work includes a literature analysis of previous experiments with incentive mechanisms in the mobility sector. Furthermore, preliminary studies and initial data collection are to be carried out and evaluated.

The research questions of the work can be summarized as follows:

Which experiments on incentives for sustainable mobility behavior are there in the literature so far?

What can a meaningful experiment design look like? What are the factors to consider when designing and running an experiment?

The permanent challenge of marketing consists in recognizing the needs and desires of the customers quickly, individually and precisely and to satisfy them accordingly. However, a good half of all customers see further need for action on the part of companies. The analysis of the emotional state offers new possibilities for optimally segmenting customers and thus serving their needs in the best possible way. Possible use cases include, for example, targeted marketing, chatbots that react to emotions or making the queue dynamic. However, there are a few obstacles to overcome on the way to precise emotion extraction. The biggest hurdle, especially in German-speaking countries, is the poor or missing data basis. First, it is a relatively new field of research. On the other hand, the intonation of emotions varies across cultures and languages, which means that an analysis based on a non-German dataset does not lead to satisfactory results. Before random data is collected, many interesting questions arise: How do (potential) customers feel about the extraction of their emotions by AI for marketing purposes? In which environment (B2C/B2B) are young adults (customers) particularly willing to have their emotions analyzed? Which channels (voice, facial expressions, text) are best suited for emotion extraction? How can such an analysis be carried out in compliance with data protection? These and many other topics can be addressed in the course of a thesis.

The exact design of the topic and the procedure is determined in close consultation with the supervisor.

Language-based systems are becoming increasingly important. Companies like Google and Amazon invest large sums in the propagation of their respective systems. Little is known about the mechanisms that promote or prevent the use of such systems. Data protection is probably a big issue, especially in Germany. But maybe also a missing benefit? Or is the application considered too difficult? Many question marks accompany this question. The observation of young and old people is also of great interest.

Are there systematic differences here? The institute would like to research this question further and has purchased a set of Amazon Alexa devices for this purpose, which can be used in an empirical study. We are happy to assign the work as a tandem to several students who share a jointly developed theoretical core and investigate different groups of (potential) users. The exact design of the topic and the empirical procedure is determined in close consultation with the supervisor.

Alzheimer's disease (AD) is the most common form of dementia. Due to the increasing average life expectancy, especially in developed societies, the number of those affected is constantly increasing. Since AD ​​is defined by a gradual disappearance of memory and other cognitive functions, including language, at an early stage, it is obvious that the latter should be the focus of attention. Machine learning methods in particular have proven to be very encouraging.

However, there is a lack of research on mobile applications related to the diagnostic procedure. The aim of this thesis is to develop a conceptual framework that is suitable for use in a mobile application that supports the diagnostic process by recognizing pathological speech patterns with the help of machine learning methods. The exact design of the topic and the procedure is determined in close consultation with the supervisor.

Misinformation has emerged as one of the biggest societal problems on social media. So-called "fake news" is shared daily by millions of users on Facebook, Twitter or Instagram. Misinformation has always been a problem in societies. Social media, however, offers mechanisms that favor the spread of those. Furthermore, fact checkers are increasingly influencing the social media network The thesis deals with the possibility for users of social media to use the internet to verify information.

The aim is to examine whether users actively verify information when they are given the opportunity to do so. For example, hyperlinks should be offered as a possibility for verification in order to find out how intensively users deal with information. Furthermore, it should be found out under which circumstances users even consider verifying information. The research questions of the work can be summarized as follows:

• Under what circumstances do users consider verifying information?
• How high or low are the barriers users are willing to cross to verify information?
• What influence do individual differences have in the use of verification strategies?

The specific topic is determined in consultation.
