This paper examines the problem of hallucinations in four scientific articles generated by ChatGPT-4 from various sub-fields of business administration. Specifically, the aim is to check whether the references generated by ChatGPT exist and, if this is the case, whether they are correct. A first surprising result is that nearly 40 Prozent of the 174 sources referenced in the articles, whose bibliographic details were listed after the individual main chapters, were not included in the specially for each article generated bibliography. A check of the bibliographic entries revealed that between 18 % and 100 % of the sources in the individual articles could not be found with Google Scholar. Furthermore, half of the sources found were incorrect to varying degrees (wrong document type, wrong journal name, wrong page reference). On average, only a quarter of the bibliographic references were completely correct. In Web of Science, only a quarter of the sources could be verified, but most of them were correct. The above results show that ChatGPT-4 – besides ethical and legal concerns – should definitely not be used for writing scientific papers, as a large proportion of the references generated by ChatGPT (valid at the time of writing this paper) does not exist or is partially incorrect. Furthermore, it can be assumed that some of the article texts generated are also "invented" or come from unreferenced sources (plagiarism). Texts generated by ChatGPT must therefore be subject to a comprehensive review, which may not always be easy. The authors therefore agree with the recommendation of Gimpel et al. (2023) that ChatGPT should primarily be used as a supplement to writing (e. g., spell-checking, creating summaries, supporting the generation of ideas). [ABSTRACT FROM AUTHOR]

The current Eurocode revision process is sought to improve Eurocode 7 for application to rock engineering, while including only techniques and procedures that are in widespread customary use. The revision process has exposed much about the application of the Eurocodes to rock engineering, thereby offering hints as to what material should be included in the next revision – tentatively suggested for publication in 2035. Crucially, ideas have developed about how rock engineering practice may need to develop to embrace the principles on which the Eurocodes are based. In particular, aspects of determining the properties of rock masses, and design verification by observational methods, partial factors, numerical modelling, and prescriptive rules are all thought to require significant improvement or dramatic modification. This paper highlights challenges identified regarding the application of the Eurocodes to rock engineering, and which will need to be addressed in the future. Ideas are presented about how these challenges may be overcome, but these are given in the spirit of stimulating ongoing conversation within the rock mechanics and rock engineering community rather than presenting definite proposals.

Teacher professional development is a highly complex field because many variables influence the development process and program effectiveness. Despite this complexity recent studies indicate that professional development programs can provide benefits for teacher knowledge, attitudes and beliefs, instructional quality and school improvement. At the beginning, this paper briefly introduces an offer-and-use-model as a framework that represents different variables that may influence teacher development. Afterwards, research results are summarized and key features of effective teacher professional development (e. g. sequences of input, application and reflection, focusing on a content and on students' learning, realisation of situations in which participants experience self-efficacy) are presented. Summing up, the article closes by stressing out open questions in the field of teacher professional development. [ABSTRACT FROM AUTHOR]

Blackletter prints still challenge computers and scholars alike when it comes to accuracy of text recognition. In this paper we show our approach to evaluate OCR accuracy of old text documents. Thus we challenge funding agencies' demands on accuracy by arguing that mixed methods like scalable reading help to achieve sufficient results from text documents of insufficient accuracy.

The paper at hand raises the question of research at colleges and Universities of Applied Sciences in general, and displays a closer look at research efforts at the Department of Information Sciences at the UAS Potsdam in particular. It starts with an investigation of the general framework for research at colleges. Taking the example of the UAS Potsdam, it then illustrates additional research elements such as externally funded projects, sabbatical leaves for university teachers and options for publication – which research in general and foremost is associated with. It turns out that research is in its varied facets is extremely useful and necessary for practice-related teaching. An immediate, direct connection with teaching is crucial for colleges.
