This applies especially to the field of sustainable digitalization. The literature providesgaps in the combination of sustainable digitalization with learning, due to the rapid developments and innovationsin this field.AI-based Chatbots could be a solution to rapidly build knowledge in this fast-evolving field, as they are able to drawupon a large body of recent knowledge and allow personalized, individual learning. They are created to understandquestions and respond to users via text, voice, or avatar in an interactive manner to facilitate learning (AI-Abdullatif,2023). Thus, AI-based Chatbots could enhance student-centered e-learning, which has shown to be a valuable toolfor sustainability literacy (Diamond \& Irwin, 2013). Nonetheless, existing research does not yet provide sufficientevidence on what learning outcomes (e.g., knowledge acquisition) can be achieved with this AI-based approach tolearning. Therefore, it is crucial for us to determine whether and how they can be effectively utilized for this purpose.In this study, we examine the impact of AI-based Chatbots on learning outcomes in the context of sustainabledigitalization, in comparison to conventional digital learning methods. We conduct a field experiment with a pre-and post-test assessing the respective level of knowledge and sustainability-related competencies amongparticipants. The participants of the study (N=269) engage with different types of supported learning activitiesrelated to sustainable development. Participants are randomly assigned to one of four advanced learningtechnologies: a) AI-assisted personal tutoring (Chatbot), b) non-AI-based conversational learning and c) interactivevideo with embedded activities. Variations in learning outcomes depending on design characteristics of the learningactivity will be measured using the Self-Perceived Action Competence for Sustainability Questionnaire (SPACS-Q)(Olsson et al., 2020) as well as as well as a set of questions to assess knowledge retention.Results indicate that AI-based chatbots may be a viable method to enhance knowledge about practices in sustainabledigitalization. However, sustainability action competencies, such as confidence in one's own influence on shaping amore sustainable future and the willingness to undertake concrete actions, which may require higher-order learningprocesses, are not positively affected by short learning activities with our AI-based chatbot. We found evidence thatnon-AI-based learning activities yield similar increases in building knowledge on sustainable digitalization but alsosignificantly enhance sustainability action competencies related to potential behavioral changes.What does learner-centered pedagogy look like in reimagining the digital classroom of the future?93Assuming that our results are generalizable to other learning topics, the evidence found in this study suggests thatAI-based chatbots can contribute to addressing our most significant transformational challenges, all characterizedby a rapidly evolving knowledge base.

An example of a prototypical application - albeit based on a self-programmed interface - is Nitze's(2024) StudyBuddy, which simulates oral exams. Yet, the extent to which these AI-based exam assistants canautonomously conduct complete exam assessments—creating questions and evaluating and grading responseswithout manual oversight—is still largely unexplored. Despite the clear advantages, issues related to the quality ofthe generated content, the precision of assessments, ethical implications, and acceptance among learners persist assignificant concerns.This paper is a proof-of-concept study combined with a field experiment for an AI-based exam assistant based onthe StudyBuddy suggested by Nitze (2024). The exam assistant provides students with a set of quiz questions andcase studies based on an 80-page reader on topics in organizational behavior, offering personalized feedback andquestion-by-question scoring ranging from 0 to 100\%, along with an overall grade and personalized feedback. Toevaluate learning behavior and outcome (in the practice phase), perceived fairness (in the exam phase) and overalllearner acceptance, we run a field experiment with N=35 students enrolled in a business management program at atechnical university in Germany. They take part in a quiz assignment provided and graded by the exam assistant andsubsequently answer a survey with questions based on the Perceived Fairness scale (Sonnleitner \& Kovacs, 2020)and the Trust in Automated Systems Test (Wojton et al., 2020). Additionally, the learning outcomes are assessed ina retrospective pre-post design according to Drennan and Hyde (2008). Results will be available by the End of April2024.Insights gained from this study will shed light on the question whether custom chatbots can be effectively used forscalable, efficient assessment processes in higher education. As the ready-made interfaces already available requireminimal prerequisites and technical skills, they present an accessible opportunity for instructors to develop theirown AI-based examination tools, and to ease manual corrections, to guarantee consistent grading and to providestudents with individualized, constructive feedback on their solutions even in large courses where personalizedfeedback would not be possible when manual grading is used.The results of this study will shed light on whether customised chatbots can be effectively used for scalable, efficientassessment processes in higher education.

Being divided into several domains (for instance, text steganography, digital media steganography, and network steganography), it is crucial to provide a unified terminology as well as a taxonomy that is not limited to some specific applications or areas. A prime attempt towards a unified understanding of terms was conducted in 2015 with the introduction of a pattern-based taxonomy for network steganography. Six years later, in 2021, the first work towards a pattern-based taxonomy for steganography was proposed. However, this initial attempt still faced several shortcomings, e.g., the lack of patterns for several steganography domains (the work mainly focused on network steganography and covert channels), various terminology issues, and the need of providing a tutorial on how the taxonomy can be used during engineering and scientific tasks, including the paper-writing process.

As the consortium who published this initial 2021-study on steganography patterns, in this paper we present the first comprehensive pattern-based taxonomy tailored to fit all known domains of steganography, including smaller and emerging areas, such as filesystem steganography and cyber-physical systems steganography. Besides, to make our contribution more effective and promote the use of the taxonomy to advance research on steganography, we also provide a thorough tutorial on its utilization.

Thereby, HR practitioners often listen to their guts feeling instead of using more systematic HR practices that are, as research evidence shows, more effective for attracting, motivating and retaining talented staff. This paper elaborates on the question how SMEs may profit from the design and implementation of evidence-based, systematic HRM instruments. The analysis focuses on the antecedents of the so called science-practitioner gap in HRM and why it is even more pronounced in SMEs as compared to larger companies. As a conclusion, we find that SMEs need to design HRM instruments that are systematic and evidence-based in their approach, but can be used by HR practitioners on an intuitive basis without ex ante training or cumbersome formal procedures. However, designing HRM instruments based on a so-called "walk-up-and-use" approach means beating new paths. Given the scarce resources for people management in SMEs, such innovative HRM instruments cannot be developed by a single SME alone. Therefore, the paradigm of open cooperation as it has been successfully applied in open source software (OSS) development is evaluated , in particular whether it can be transferred on the design of HRM instruments that take into account the specific needs of SMEs. First of all, we conceptualize a general framework how HR practitioners from SMEs and HR experts from business and academia can jointly develop Open HRM instruments. Then we discuss the social side of Open HRM, in particular why someone should contribute to Open HRM without receiving immediate profits, how to ensure the quality of openly developed HRM instruments and other gov-ernance issues. As a conclusion, we find that-despite a number of technical and social challenges that have to be overcome-Open HRM has a great potential in order to open up evidence-based HRM for SMEs.}, language = {de} } @incollection{LevinaMattern2023, author = {Levina, Olga and Mattern, Saskia}, title = {Ethical and Legal Analysis of Machine Learning Based Systems: A Scenario Analysis of a Food Recommender System}, series = {Recommender Systems: Legal and Ethical Issues}, booktitle = {Recommender Systems: Legal and Ethical Issues}, isbn = {978-3-031-34806-8}, doi = {10.1007/978-3-031-34804-4_9}, pages = {165 -- 185}, year = {2023}, abstract = {Laws are the reflection of the ethical and moral principles of the society.

This scenario analysis- based research focuses on a classic but fictional food recommender system and the ethical issues that might occur from its usage. The recommender system is taken here as an example of machine learning-based systems (MLS) that can often be found in the individual, business and administrative applications. The research compares the existing legal solutions, with the focus on the GDPR legislation, and the discovered ethical issues. The ethical analysis is led along the ALTAI principles suggested by the European Commission, the common good approach as well as the general principles constituted in human rights. While the GDPR-based analysis showed that this data- and privacy-based legislation addressed most of the identified ethical issues, questions related to the common good approach in the context of environment and mobility that arise due to the wide spectrum of the MLS usage require further legal discussion. The application of the two approaches shows that conducting the ethical and legal analysis is beneficial for both the designers of such MLS as well as the legal actors.

Based on good practices of recent MML implementations, a lightweight approach is developed. It involves an instructional blueprint and an open-source, low-threshold technology for MML, and meets the specific needs of workers in learning-deprived fields.

To validate its operation and usefulness, we apply it to two countries, Germany and Spain, allowing to study the main threats that affect medical IT systems in these countries. Our initial findings reveal that 20\% of German hosts and 15\% of Spanish hosts tagged as medical devices have at least one CVE (Common Vulnerabilities and Exposures) with a CVSS (Common Vulnerability Scoring System) graded as critical (i.e., value 8 or greater). Moreover, we found that 74\% of CVEs found in German hosts are dated from earlier than 2020, whereas for Spanish hosts the percentage is 60\%. This indicates that medical IT systems exposed to the Internet are seldom updated, which further increases their exposure to cyberthreats.

Unfortunately, current mechanisms to distinguish between network steganographic embedding methods and embedded message types need improvement for a potential attribution of attackers. For the analysis of steganographic em- bedding methods which are utilized in stealthy malware, the work presented in this paper builds upon a state-of-the-art analysis testbed proposed earlier, which is recapitulated here. It offers the opportunity to analyze network steganographic embedding methods in ICS to elaborate methods to detect and distinguish between them to gain forensic information for attribution of potential attackers and their methods. In this work, we introduce a novel machine learning based approach to distinguish between five selected embedding methods and two embedded message types. We use the analysis testbed to evaluate and determine the accuracy of the novel approach compared to a state-of-the-art approach. In our extensive evaluation, our novel approach has shown to be able to distinguish between network steganographic embedding methods with an average accuracy of 85.7\%, which is an improvement in comparison to the state-of-the-art by +5.9\% and enables a more accurate attribution of attackers. Additionally, the novel approach is able to improve the accuracy of distinction between embedding method and embedded message type by +9.3\% in comparison to the evaluated state-of-the-art approach.}, language = {en} }
