T1 - SAP-Ausbildung - Digitalisierung und Pandemie als Herausforderung
JF - ERP Management
N2 - Unternehmen und Unternehmens-IT stehen im Zeitalter der Digitalisierung vor großen Umbrüchen. Geschäftsprozesse und die eingesetzten IT-Systemlandschaften verändern sich im schnellen Takt, teilweise werden erprobte Geschäftsmodelle disruptiv durch völlig neue Technologien ergänzt oder gar ersetzt. Dieses schnelllebige Umfeld erfordert eine intensive und qualitativ hochwertige Ausbildung der Mitarbeiter. Präsenzschulungen sind in Zeiten der Corona-Pandemie aber schwer zu realisieren. Wie eine praxisnahe und Fallstudien-basierte Ausbildung im ERP-Kontext trotzdem möglich ist, zeigt das E-Learning-basierte Programm erp4students der Technischen Hochschule Brandenburg am Beispiel von 13 Modulen im Umfeld neuester SAP-Technologien.

T1 - Using Advanced Learning Technologies to Boost Sustainability Education: The Role of AI-based Chatbots
T2 - EDEN 2024 Annual Conference, University of Graz, Graz, Austria, 2024
N2 - In the face of the 2030 Agenda of the United Nations, the everchanging knowledge base of sustainability and therelated learning become vital. 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. Further research is particularly needed with respect to the preferable designcharacteristics of digital learning activities (both AI-based and non-AI-based) to achieve optimal outcomes in buildingsustainability competencies.

T1 - Fast Protein and Metabolites (Nucleotides and Nucleosides) Liquid Chromatography Technique and Chemical Sensor for the Assessment of Fish and Meat Freshness
JF - Chemosensors
N2 - Fast protein and metabolite liquid chromatography (FPLMC) was introduced years ago to enable the easy separation of high-molecular compounds such as proteins from small molecules and the identification of the low-molecular substances. In this paper, the method is applied for the rapid evaluation of freshness and monitoring the aging of animal meat and fish. A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255–265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min. Strict isochronism between the elution of ATP metabolites, mainly hypoxanthine (Hx) and inosine monophosphate (IMP), and the time of maturation of meat or fish, was discovered. A new freshness index H* = [Hx]/[IMP] was introduced, which is proportional to the instrumental delay time in the FPMLC chromatograms: the H* index < 0.5 indicates the presence of inosine monophosphate (IMP) and the high quality of the meat or fish. Reasonably strong correlations were revealed between data obtained by FPMLC and total volatile basic nitrogen TVB-N (for fish) or volatile fatty acids VFA (for meat) content. Moreover, putative nucleotide salvage and an increase in the concentration of IMP were observed in fish after heat treatment using the FPMLC sensor and NMR technique.

T1 - Utilizing Chatbots for Automating Examinations in Higher Education: Perceived Fairness, Trust and Learning Outcomes
T2 - EDEN 2024 Annual Conference, University of Graz, Graz, Austria, 2024
N2 - Large Language Models (LLM) are increasingly used to support educational assessment (González-Calatayud et al.,2021), offering a promising approach to addressing challenges associated with scalability, consistency, andpersonalized feedback that manual assessment implies (Fagbohun et al., 2024).Pre-configured interfaces for building custom chatbots based on common AI models provide a low-level approachfor educators to design their own AI-based examination tools that ask learners questions and provide feedback onthe answers. 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. The readily available interfaces, requiring minimal prerequisites andHow do we promote fairness in digital learning futures?22technical skills, enable educators to develop their own AI-based assessment tools. This would open opportunitiesfor educators to build their own AI-based assessment tools and facilitate manual corrections, ensure consistentgrading and provide students with individualised, constructive feedback, even in large courses where personalisedfeedback would not be possible with manual grading.

T1 - A Generic Taxonomy for Steganography Methods
N2 - A unified understanding of terms and their applicability is essential for every scientific discipline: steganography is no exception. 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.

T1 - Open Design of HRM Instruments: new perspectives on people management in SMEs
N2 - When it comes to human resource management (HRM), small and medium-sized enterprises (SMEs) primarily rely on informal approaches. 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.

T1 - Ethical and Legal Analysis of Machine Learning Based Systems: A Scenario Analysis of a Food Recommender System
T2 - Recommender Systems: Legal and Ethical Issues
N2 - Laws are the reflection of the ethical and moral principles of the society. While the use of technology influences users’ behavior in a pace that is affected by the technology introduction to the market, legal activities can be driven by the society as the results of such interactions. 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. The findings can enhance the design and functions of a user-facing MLS as well as influence or validate legal activities.

T1 - Towards Personal Assistants for Energy Processes Based on Locally Deployed LLMs
T2 - Proceedings of the 17th International Conference on Agents and Artificial Intelligence (ICAART 2025) , 2025, Porto, Portugal
N2 - This paper presents a coaching assistant for network operator processes based on a Retrieval-Augmented Gen-
eration (RAG) system leveraging open-source Large Language Models (LLMs) as well as Embedding Models.
The system addresses challenges in employee onboarding and training, particularly in the context of increased
customer contact due to more complex and extensive processes. Our approach incorporates domain-specific
knowledge bases to generate precise, context-aware recommendations while mitigating LLM hallucination.
We introduce our systems architecture to run all components on-premise in an our own datacenter, ensuring
data security and process knowledge control. We also describe requirements for underlying knowledge doc-
uments and their impact on assistant answer quality. Our system aims to improve onboarding accuracy and
speed while reducing senior employee workload.
The results of our study show that realizing a coaching assistant for German network operators is reasonable,
when addressing performance, correctness, integration and locality. However current results regarding accu-
racy do not yet meet the requirements for productive use.

T1 - Operationalizing Ethics for Information Systems Design - A Tool for Ethical Software
T2 - Konferenz: Twenty-ninth Americas Conference on Information Systems (AMCIS), Panama, 2023
N2 - Propagation of information technology in the increasingly diverse domains, raises question concerning moral implications. While the number of ethical principles in the IT design is growing, they do not necessarily apply to specific products, which means developers and e.g. purchasing agent need to contextualize them for each specific IT product. This paper describes an actionable artifact that allows assessment of ethical non-functional requirements of an information system through operationalization of ethical values, Ethical Software Assessment Tool (ESAT). It is based on a survey of values that are currently considered in research and practice as well as in legal initiatives in IT context. The ethical approach and principles operationalized in ESAT are presented and discussed.

N2 - Steganography embraces several hiding techniques which spawn across multiple domains. However, the related terminology is not unified among the different domains, such as digital media steganography, text steganography, cyber-physical systems steganography, network steganography (network covert channels), local covert channels, and out-of-band covert channels. To cope with this, a prime attempt has been done in 2015, with the introduction of the so-called hiding patterns, which allow to describe hiding techniques in a more abstract manner. Despite significant enhancements, the main limitation of such a taxonomy is that it only considers the case of network steganography. Therefore, this paper reviews both the terminology and the taxonomy of hiding patterns as to make them more general. Specifically, hiding patterns are split into those that describe the embedding and the representation of hidden data within the cover object. As a first research action, we focus on embedding hiding patterns and we show how they can be applied to multiple domains of steganography instead of being limited to the network scenario. Additionally, we exemplify representation patterns using network steganography.

T1 - Folgenabschätzung bei Innovation, Technologie und Management
JF - Ideen- und Innovationsmanagement
N2 - Menschen in Organisationen treffen Entscheidungen. In der Regel wird ein Ziel angestrebt und die Entscheidung soll Maßnahmen in Gang bringen, welche die Erreichung des Ziels befördern. Den finalen Entscheidungen gehen Prozesse voraus, welche die Entscheidungsfindung vorbereiten. In diesem Rahmen werden etwaige Kon strukte – wie Handlungen, Technologien, Produkte, Verfahren, Steuerungssysteme – in Bezug auf ihren Beitrag zur Zielerreichung bewertet. Nun ist es nicht neu, dabei eine ganzheitliche Bewertung anzumahnen und nicht nur auf eine Wirkung zu blicken. Dennoch erhält man oft den Eindruck, dass im Rahmen von Entscheidungsfindungen in Politik, Gesellschaft, öffentlichen Institutionen aber eben auch Unternehmen zu wenig auf etwaige weitere Neben- und Folgewirkungen von Entscheidungen geblickt wird. Daher wird gefragt, ob die Grundidee des Ansatzes der Technologiefolgenabschätzung hilfreiche Instrumente bietet, welche die Entscheidungsprozesse in den betrieblichen Feldern Innovation, Technologieentwicklung und Management anreichern können.

N2 - Die Digitalisierung ist eine der Herausforderungen der heutigen Zeit. Einhergehend mit der Zunahme der Nutzung des Internets in vielen Lebensbereichen steigt auch die Wichtigkeit für Unternehmen, einen repräsentativen Auftritt zu etablieren. Für kleine und mittlere Unternehmen bedeutet das Betreiben und Pflegen einer Onlinepräsenz oftmals einen hohen finanziellen und zeitlichen Aufwand. Ziel des vorliegenden Arbeitspapiers ist es, kleinen und mittleren Unternehmen eine Alternative zu herkömmlichen Content Management Systemen darzulegen und sie bei der Entscheidungsfindung zu unterstützen. Zur Beantwortung der Forschungsfragen wurde der methodische Ansatz einer Literatur- und Internetrecherche verwendet. Aus der Analyse konnten drei Online Business Plattformen identifiziert, sowie deren Vor- und Nachteile gegenüber Content Management Systemen dargestellt werden. Anschließend wurden Kriterien definiert und Empfehlungen dargelegt, welche kleine und mittlere Unternehmen im Entscheidungsprozess unterstützen sollen. Letztlich wurden die Einrichtung sowie die wichtigsten Funktionen einer Plattform dargestellt. Die Ergebnisse zeigen, dass die Nutzung einer Onlineplattform für lokal begrenze Unternehmen mit geringen Anforderungen an die Funktionalität und hoher Kostensensibilität eine sinnvolle Alternative ist. Abschließend wurde anhand des realen Fallbeispiels „Google My Business“ (seit 2022: „Google Business Profile“) auf die Funktionen sowie Vorteile und Möglichkeiten einer solchen Plattform eingegangen.
N2 - Digitalization is one of the big challenges of our time. Along with the increased online life, the importance for companies to establish a representative online presence is growing as well. Especially for small and medium size companies, the operation and maintenance of an online presence means a high effort in terms of time and financial investment. The aim of this study is to provide an alternative to common content management systems for small medium size companies. In addition, they should be supported in the decision making process. To answer the research questions the methodical approach of a literature and internet research was used. From the analysis, three online business platforms were identified and their advantages and disadvantages compared to content management systems were presented. Subsequently, criteria were defined and recommendations were presented, which should support small and medium-sized enterprises in the decision-making process. Finally, the setup as well as the most important functions of a platform were presented. The results show that the use of an online platform is a sensible alternative for locally limited companies with low functionality requirements and high cost sensitivity. Finally, the functions as well as advantages and possibilities of such a platform were discussed on the basis of the real case study "Google My Business" (since 2022: "Google Business Profile")

T1 - Machine-Learning Verfahren für eine nachhaltige Letzte-Meile-Logistik
N2 - Dieser Beitrag entwickelt ein Konzept zur praktischen Umsetzung eines Machine- Learning Verfahrens zum Lösen von Vehicle Routing Problemen im Kontext einer nachhaltigen “Letzte-Meile”-Logistik, welches durch einen Prototyp umgesetzt und getestet wurde. Der Prototyp basiert auf dem “Reinforcement Learning”-System und verwendet als Algorithmus “REINFORCE mit Baseline”. In einer Vergleichsanalyse wurde der Prototyp mit dem bekannten Vertreter Google-OR, anhand von zwei Anwendungsszenarien, verglichen. Der Prototyp überzeugt dabei in der Laufzeit und dem Automatismus. Es konnte festgestellt werden, dass eine Verwendung von Lernenden-Systemen für das Vehicle Routing Problem sich bei nur bei einem größeren Stoppvolumen und einer erweiterten IT-Infrastruktur empfiehlt.

T1 - Evaluation of AI-based use cases for enhancing the cyber security defense of small and medium-sized companies (SMEs)
JF - Electronic Imaging
JF - IS&T International Symposium on Electronic Imaging : Mobile Devices and Multimedia: Enabling Technologies, Algorithms, and Applications, 2022
N2 - Companies are increasingly facing the challenges of a persistent cyber threat landscape. By means of AI, cyber attacks can be efficiently conducted more successful through offensive AI. As for cyber defense, AI can be also utilized against cyber threats (defensive AI). Due to limited resources, especially in small and medium-sized companies (SMEs), there is a need to deploy more effective defensive cyber security solutions. Precisely, the adaptation of AI-based resilient defenses must be driven forward. Therefore, the aim of this paper is to identify and evaluate AI-related use cases with a high impact potential on the cyber security level, while being applicable to SMEs at the same time. In order to reach the research goal, an extensive literature review of several online catalogs, surveys and online platforms was conducted. In conclusion, seven crucial AI-based security features were outlined that are providing a high impact potential to the security level for SMEs. Afterwards, the results are discussed and set into a broader context. Even though AI-based security solutions are providing a large range of advantages, certain challenges and barriers using AI-related security applications are addressed in the paper as well. A high need for usable state of the art AI based cyber security solution for SMEs was identified.

N2 - Due to the increasing number of complaints alleging privacy violations against companies to data protection authorities, the translation of business goals to system design goals and the subsequent consequences for customers’ privacy poses a challenge for many companies. For this reason, there is a need to bridge the economics of privacy and threats to privacy. To this end, our work relies on the concept of privacy as contextual integrity. This framework defines privacy as appropriate information flows subjected to social norms within particular social contexts or spheres. In this paper, we introduce a preliminary version of a semantic model which aims to relate and provide understanding on how well-established business goals may affect their customers’ privacy by designing IoT devices with permission access, data acquired by sensors, among other factors. Finally, we provide a use case application showing how to use the semantic model. The model aims to be an educational tool for professionals in business informatics during the modeling and designing process of a product which may gather sensitive data or may infer sensitive information, giving an understanding of the interaction of the product and its footprint with diverse actors (humans or machines). In the future, a further complete model of the presented may also target other groups, such as law enforcement bodies, as part of their educational training in such systems.

T1 - Scan to Learn: A Lightweight Approach for Informal Mobile Micro-Learning at the Workplace
T2 - Konferenz: IARIA The Fifteenth International Conference on Mobile, Hybrid, and On-line Learning; Venice (Italy)
N2 - Informal learning at the workplace is a crucial ingredient in updating and upskilling today's workforce, but in many jobs, informal learning opportunities are scarce. Bite-sized learning via mobile devices (Mobile Micro-Learning, MML) can be a powerful means to enhance informal work-related learning also in such learning-deprived fields. 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. The main idea is a scan-to-learn system where Quick Response (QR) codes are attached to physical objects in the work environment. Workers can scan the QR codes to learn and are directed to short, interactive learning nuggets. For evaluation, a proof-of-concept is provided.

T1 - Threat Analysis of Steganographic and Covert Communication in Nuclear I&C Systems
T2 - Konferenz: International Conference on Nuclear Security: Sustaining and Strengthening Efforts (ICONS), Vienna, Austria, 2020/ Konferenzband: International Conference on Nuclear Security: Sustaining and Strengthening Efforts
N2 - Steganographic and covert communication is increasingly used for hiding attacks. Often information hiding is used by attackers in advanced persistent threats in order to operate without being noticed. Attackers might use it to hide data exfiltration or control channels for persistent malware. The paper analyzes potential threats to operational technology by investigating different communication protocols towards their suitability as cover channels. Using a generalized network architecture model and the communication flows of nuclear power plants, the attack potential using information hiding is exemplary assessed. An example for a supply chain attack for command injection is given on the foundation of the OPC UA protocol and an off-theshelf programmable logic controller. Subsequently, recommendations for a strategic and operational preparation for operators towards the prevention and detection of information hiding attacks are derived.

T1 - Initial solidification dynamics of spreading droplets
JF - Physical Review Fluids
N2 - When a droplet is brought in contact with an undercooled surface, it wets the substrate and solidifies at the same time. The interplay between the phase transition effects and the contact-line motion, leading to its arrest, remains poorly understood. Here we reveal the early solidification patterns and dynamics of spreading hexadecane droplets. Total internal reflection imaging is employed to temporally and spatially resolve the early solidification behavior. With this, we determine the conditions leading to the contact-line arrest. We quantify the overall nucleation behavior, i.e., the nucleation rate and the crystal growth speed and show its sensitivity to the applied undercooling of the substrate. We also show that for strong enough undercooling it is the rapid growth of the crystals which determines the eventual arrest of the spreading contact line. By combining the Johnson-Mehl-Avrami-Kolmogorov nucleation theory and scaling relations for the spreading, we calculate the temporal evolution of the solid area fraction, which is in good agreement with our observations.

T1 - The structure of disintegrating defect clusters in smectic C freely suspended films
JF - Soft Matter
N2 - Disclinations or disclination clusters in smectic C freely suspended films with topological charges larger than one are unstable. They disintegrate, preferably in a spatially symmetric fashion, into single defects with individual charges of +1, which is the smallest positive topological charge allowed in polar vector fields. While the opposite process of defect annihilation is well-defined by the initial defect positions, disintegration starts from a singular state and the following scenario including the emerging regular defect patterns must be selected by specific mechanisms. We analyze experimental data and compare them with a simple model where the defect clusters adiabatically pass quasi-equilibrium solutions in one-constant approximation. It is found that the defects arrange in geometrical patterns that correspond very closely to superimposed singular defect solutions, without additional director distortions. The patterns expand by affine transformations where all distances between individual defects scale with the same time-dependent scaling factor proportional to the square-root of time.

T1 - Coalescence of biphasic droplets embedded in free standing smectic A films
JF - Soft Matter
N2 - We investigate micrometer-sized flat droplets consisting of an isotropic core surrounded by a nematic rim in freely suspended smectic A liquid-crystal films. In contrast to purely isotropic droplets which are characterized by a sharp edge and no long-range interactions, the nematic fringe introduces a continuous film thickness change resulting in long-range mutual attraction of droplets. The coalescence scenario is divided in two phases. The first one consists in the fusion of the nematic regions. The second phase involves the dissolution of a thin nematic film between the two isotropic cores. The latter has many similarities with the rupture of thin liquid films between droplets coalescing in an immiscible viscous liquid.
Coalescence of biphasic droplets in free-standing smectic films is controlled in part by the rupture of a thin nematic membrane separating the isotropic droplet cores.

T1 - Climate justice - dimensions and conflicts
N2 - Probably no-one will publicly admit that justice is not important to him. The allegation of injustice is used to describe moral positions and justify demands. However, there is no simple and unambiguous description of just positions or just actions. To overcome the man-made climate crisis, a fair distribution of benefits and burdens is called for. Some stakeholders also use the argument of justice to disguise their interests. The question to be clarified is: Who may cause how much damage to whom and who must make what efforts to compensate for the damage and prevent future damage? This text reports on attempts to establish an ethical foundation for climate justice and on international political activities that claim to achieve greater climate justice.

T1 - Puzzle away the Puzzledness: Action-Design Study of an Educational Escape Room for Intervention in SMEs’ Perception towards ICT Adoption
T2 - Konferenz: 57th Hawaii International Conference on System Sciences (HICSS); Honolulu, HI, USA
N2 - Digital transformation initiatives in small and medium-sized enterprises (SME) are often hampered by individual practitioners' perceptions of information and communication technology (ICT). This research employs an educational escape room (ER) game for an intervention towards informed decision-making on ICT adoption in SMEs. ER design and implementation are elaborated and consequently tested with SME practitioners, all embedded in an action-design study based on a qualitative research methodology. The result highlights a trade-off between creating immersive game experiences and achieving learning objectives. Still, the outcome implies an impact on players' perception of ICT integrated in the ER. The findings contribute to the emerging field of serious games for learning and shed light on the potential of game-based interventions for SMEs.

T1 - What is Digital about Digital Innovation? An Ontological Discussion of Digitality
T2 - Konferenz: 29th Americas Conference on Information Systems
N2 - "Digital" is a popular adjective for concepts related to electronic, computerized or networked processes in current research and practice. From an ontological-theoretical perspective, the prevalence of digital things triggers the question, how Digitality itself could be conceptualized. This article studies the ontology of Digitality and consequently discusses Digital Innovation (DI) from a new perspective. First, literature on Digitality is analyzed. Based on the findings, an ontological conceptual framework of Digitality (OCFD) is proposed. It describes four layers of Digitality: physical foundations, virtuality, digital culture and world, and digital metaphysics. From a human perspective, requirements to grasp and embody Digitality are highlighted, as well as the expansion of reality. Finally, Digitality is discussed as a paradigm of DI and exemplary digital phenomena are projected onto the OCFD. This paper contributes to DI research and practice through theory-building towards a better understanding of ontological characteristics and practical implications of Digitality in DI.

N2 - Das Ziel der vorliegenden Arbeit ist es, die These zu bestätigen, dass sich eine mobile Incident-Response-Netzwerksensorik in einer zuvor unbekannten Netzwerkumgebung innerhalb eines festgelegten Zeitraums installieren lässt und die forensische Analyse entscheidend unterstützen kann. Dazu wurden Anforderungen an die mobile Netzwerksensorik mithilfe von zwei Experteninterviews erhoben, deren Erfüllung an die Bestätigung der These gekoppelt ist. Zur Umsetzung der Anforderungen wurden Soft- und Hardwarekomponenten ausgewählt, die in Kombination die Netzwerksensorik bilden. Bei der Softwareauswahl zeigte sich, dass die Plattformlösung Security Onion aufgrund der Vielzahl implementierter Softwarekomponenten, der umfangreichen Dokumentation und der Architektur besser geeignet ist, die Projektanforderungen zu erfüllen und damit die These zu bestätigen, als Clear NDR. Durch drei Versuche konnte die These erfolgreich bestätigt werden. Damit liefert die Arbeit wichtige Grundlagen für die Implementierung einer mobilen Netzwerksensorik. Durch weitere Versuche und die in dieser Arbeit vorgestellten Hardwareempfehlungen kann in Zukunft eine praxistaugliche mobile Netzwerksensorik in Betrieb genommen werden.

T1 - Symmetry Breaking and Emergence of Directional Flows in Minimal Actomyosin Cortices
JF - Cells
N2 - Cortical actomyosin flows, among other mechanisms, scale up spontaneous symmetry breaking and thus play pivotal roles in cell differentiation, division, and motility. According to many model systems, myosin motor-induced local contractions of initially isotropic actomyosin cortices are nucleation points for generating cortical flows. However, the positive feedback mechanisms by which spontaneous contractions can be amplified towards large-scale directed flows remain mostly speculative. To investigate such a process on spherical surfaces, we reconstituted and confined initially isotropic minimal actomyosin cortices to the interfaces of emulsion droplets. The presence of ATP leads to myosin-induced local contractions that self-organize and amplify into directed large-scale actomyosin flows. By combining our experiments with theory, we found that the feedback mechanism leading to a coordinated directional motion of actomyosin clusters can be described as asymmetric cluster vibrations, caused by intrinsic non-isotropic ATP consumption with spatial confinement. We identified fingerprints of vibrational states as the basis of directed motions by tracking individual actomyosin clusters. These vibrations may represent a generic key driver of directed actomyosin flows under spatial confinement in vitro and in living systems.

T1 - Developing Digital Competencies in Small and Medium-Sized Enterprises Through Microlearning Applications: A Research Agenda
T2 - Konferenz: Perspectives in Business Informatics Research
22nd International Conference on Business Informatics Research, BIR 2023, Ascoli Piceno, Italy, September 13–15, 2023, Proceedings
N2 - This article presents a research outline on the use of microlearning applications to develop digital competencies in Small and Medium-sized Enter-prises (SMEs). The digital transformation of businesses has become essential for their survival, and SMEs need to develop digital competencies (DC) to remain competitive in the market. Microlearning (ML), a form of learning that involves small, bite-sized learning modules, has been gaining popularity in recent years as a way to efficiently and effectively develop skills. Through a semi-systematic literature review approach, our study examines prevalent knowledge in the area of ML and DC and discusses interrelations. As a result, we propose a research roadmap consisting of six research questions targeting four dimensions of ML for DC development in SMEs: 1) context, 2) formats, 3) reward system, and 4) complexity level.

T1 - Small Businesses Participating in Digital Platform Ecosystems - A Descriptive Literature Review
T2 - Digital Transformation. PLAIS EuroSymposium 2023. Lecture Notes in Business Information Processing
N2 - The emergence of digital multi-sided platforms has disrupted day-to-day business in many industries. Nowadays, many small businesses participate in digital platform (DP) ecosystems and act as value creators or complementors. Investigating the small business perspective does not have a rich tradition in platform research yet. In response, this paper presents a systematic literature review (SLR) analyzing the thematic points of focus and highlighting new avenues for information systems and small business research. We find that objectives related to digital transformation, digital strategy- and business model-development, and DP adoption are fundamental topics in the conjunction of small business and DP ecosystems. Based on the findings, an agenda for future research is developed, including propositions for practice-oriented and human-centered approaches fostering sustilience, innovation capabilities and digital leadership competencies in small businesses facing DP ecosystem participation.

N2 - This study analyzes approaches to decarbonize the energy supply of the secondary steel processing industry. Therefore, real data from a secondary steel production company is used in combination with state-of-the art low carbon energy supply technologies. Also, the use of waste heat from a pusher furnace for process integration is considered. The developed temporal process model allows holistic optimizing and expanding the steel making process system regarding techno-economic criteria. As we show, implementing the annual heat demand of a municipality shows that a nearly 100 % self-sufficient heat supply is possible.

T1 - Mitigating Hallucination by Integrating Knowledge Graphs into LLM Inference – a Systematic Literature Review
T2 - Proceedings of the 63rd Annual Meeting of the Association for Computational Linguistics (Volume 4: Student Research Workshop)
N2 - Large Language Models (LLMs) demonstrate strong performance on different language tasks, but tend to hallucinate – generate plausible but factually incorrect outputs. Recently, several approaches to integrate Knowledge Graphs (KGs) into LLM inference were published to reduce hallucinations. This paper presents a systematic literature review (SLR) of such approaches. Following established SLR methodology, we identified relevant work by systematically search in different academic online libraries and applying a selection process. Nine publications were chosen for indepth analysis.
Our synthesis reveals differences and similarities of how the KG is accessed, traversed, and how the context is finally assembled. KG integration can significantly improve LLM performance on benchmark datasets and additionally to mitigate hallucination enhance reasoning capabilities, explainability, and access to domain-specific knowledge. We also point out current limitations and outline directions for future work.

T1 - Assessing Cybersecurity of Internet-Facing Medical IT Systems in Germany & Spain Using OSINT Tools
N2 - This paper investigates cybersecurity threats in medical IT (Information Technology) systems exposed to the Internet. To that end, we develop a methodology and build a data processing pipeline that allows to gather data from different OSINT (Open Source Intelligence) sources, and processes it to obtain relevant cybersecurity metrics. 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. Based on these initial findings, we finish the paper providing some insights on how to improve cybersecurity of these systems.

T1 - Attack Detection for Medical Cyber-Physical Systems – A Systematic Literature Review
JF - IEEE Access
N2 - The threat situation due to cyber attacks in hospitals is emerging and patient life is at risk. One significant source of potential vulnerabilities is medical cyber-physical systems (MCPS). Detecting intrusions in this environment faces challenges different from other domains, mainly due to the heterogeneity of devices, the diversity of connectivity types, and the variety of terminology. To summarize existing results, we conducted a structured literature review (SLR) following the guidelines of Kitchenham et al. for SLRs in software engineering. We developed six research questions regarding detection approach, detection location, included features, adversarial focus, utilized datasets, and intrusion prevention. We identified that most researchers focused on an anomaly-based detection approach at the network layer. The primary focus was on the detection of malicious insiders. While several researchers used publicly available datasets for training and testing their algorithms, the lack of suitable datasets resulted in the development of testbeds consisting of various medical devices. Based on the results, we formulated five future research topics. First, the special conditions of hospital networks, the MCPS deployed within them, and the contrasts to other IT and OT environments should be examined. Thereupon, MCPS-specific datasets should be created that allow researchers to address the health domain’s unique requirements and possibilities. At the same time, endeavors aimed at standardization in this area should be supported and expanded. Moreover, the use of medical context for attack detection should be further explored. Last but not least, efforts for MCPS-tailored intrusion prevention should be intensified. This way, the emerging threat landscape can be addressed, IT security in hospitals can be improved, and patient health can be protected.

T1 - Advancing Image Spam Detection: Evaluating Machine Learning Models Through Comparative Analysis
JF - Applied Sciences
N2 - Image-based spam poses a significant challenge for traditional text-based filters, as malicious content is often embedded within images to bypass keyword detection techniques. This study investigates and compares the performance of six machine learning models—ResNet50, XGBoost, Logistic Regression, LightGBM, Support Vector Machine (SVM), and VGG16—using a curated dataset containing 678 legitimate (ham) and 520 spam images. The novelty of this research lies in its comprehensive side-by-side evaluation of diverse models on the same dataset, using standardized dataset preprocessing, balanced data splits, and validation techniques. Model performance was assessed using evaluation metrics such as accuracy, receiver operating characteristic (ROC) curve, precision, recall, and area under the curve (AUC). The results indicate that ResNet50 achieved the highest classification performance, followed closely by XGBoost and Logistic Regression. This work provides practical insights into the strengths and limitations of traditional, ensemble-based, and deep learning models for image-based spam detection. The findings can support the development of more effective and generalizable spam filtering solutions in multimedia-rich communication platforms.

T1 - Lessons learned from building sustainable municipal LoRaWan infrastructure
JF - International Journal On Advances in Networks and Services
N2 - Abstract—This paper introduces the LoRaWAN Collaboration Framework (LCF), a strategic blueprint for deploying and managing LoRaWAN infrastructures in smart cities with an emphasis on rural and small municipalities. LoRaWAN technology distinguishes itself by its capability to support long-range, low-power IoT applications, making it ideal for extensive and sparsely populated areas. The LCF aims to address common challenges in these settings, such as limited technical expertise, financial constraints, and the need for cross-municipal cooperation. It outlines roles and responsibilities across various stakeholders including municipal authorities, IT service providers, application developers, and end-users. The framework emphasizes the balance of technological, economic, social and ecological sustainability in line with the United Nations' Sustainable Development Goals. In this paper, we describe the experiences from several LoRaWAN projects in small towns and municipalities in Germany and give some insights to these use cases, the derived collaboration framework, and other arguments to consider before implementing LoRaWAN infrastructures.
