Short Description of Content: Highway reservation systems have gained much attention as a potential strategy to improve the utilization of limited highway resources. In this research, a highway reservation system that uses blockchain technology to improve highway utilization is analyzed. Drivers are enabled to use pre-booked priority-lanes; booking and payment should be realized by blockchain technology. This approach allows time slots to be booked, while also incentivizing users to release reservations in anticipation of congestion.

Research Questions:

• How do driver and the transportation system benefit from a blockchain-based highway reservation system?
• How can late or early entry into the reserved lane be handled?
• What percentage of drivers are likely to effectively use the highway reservation system?

Method:

• Modeling the freeway reservation system with a mathematical algorithm
• Evaluation of the highway reservation system using the microscopic traffic simulation software "SUMO"
• Evaluation of the effectiveness of the blockchain-based reservation system

Short Description of Content

This doctoral thesis deals with tax measures that are intended to promote research and development investments by private companies. After a definition of the term, the type of regulation is categorized in economic as well as (constitutional and EU) legal terms. The main part of the work consists of a country comparison. France, the Netherlands and the United Kingdom, which have already integrated such tax measures into their profit tax systems for several years, are included in the analysis. Following a presentation of the relevant basic aspects of the respective national profit tax systems, the tax measures for promoting research and development are examined in detail. Finally, conclusions for the structure in Germany will be derived from the observations.

Research Questions

• How can the action be designed to be as economically effective and efficient as possible?
• To what extent does the legal regulatory framework to which the measure is subject restrict the design options?
• How do other countries proceed with tax incentives for private R&D investments and what can be derived from this for the design in Germany?

Method: Normative

Duration: 3 years

Short Description of Content: The topic of the study is the use of metaphors in collegial counseling processes. Metaphors are an elementary component of our linguistic communication, which we use to communicate about the world, our thoughts and feelings. Metaphors are increasingly used when it comes to the explication of personal experiences. Collegial consultations are such a place, because they deal with a personally experienced problem in a professional context. In consultations, however, it is not only the problem itself that is expressed by means of metaphorical expressions. The relationship with the counsellor(s) and the counselling process per se can also be conceptualized in metaphors. For example, counseling can be framed metaphorically as cooperation, as a path or as a struggle or teaching situation.

Research Question: What metaphorical patterns are used by the participants to understand the peer counseling interaction?

Method: Triangulation of metaphor and conversation analysis

Duration: January 2021-August 2024
