Phase-space-based fusion of angular and height data in tactile and optical surface texture measurement for tribological analysis
(Elsevier, 2026-01-08) Eifler, Matthias; Brodmann, Boris
Accurate characterization of surface topography is essential for understanding and optimizing tribological processes. A wide range of tactile and optical measurement techniques – such as stylus profilometry, scattered light sensors, white light interferometry, confocal microscopy, and focus variation – are available, each with distinct advantages and inherent nonlinearities that may introduce method-specific artefacts. This study introduces a novel approach for mapping and assessing surface topography using a phase-space representation that integrates both height and angular information and enables a joint analysis and fusion of both characteristics. This exhibits potential for efficient and compact monitoring of tribological processes. We investigate the informational content and limitations of various measurement techniques by surface texture and angular parameters, highlighting the differences and the impact of the statistics of a surface. Then, the overall height and angular distributions of the measured topographies are compared. Angular representations offer an additional dimension of analysis, enhancing the robustness of surface characterization. For the angular distribution, tactile and optical methods often yield differing results, particularly for complex surface features. A direct angular measurement offers another perspective on the surface topography and the combination of height and angular information enables a more holistic surface description. The proposed phase-space representation is exemplified through the analysis of cylinder liner surfaces, illustrating its potential to improve the accuracy and interpretability of tribological assessments and demonstrating the potential of this representation to expose even slightest changes in the surface topography. The fusion of the independent variables height and slope can allow a precise monitoring of tribological processes where only one of the two distributions may change and thus allows a novel perspective on the tribological assessment of surfaces.
Wenn Strategien scheitern: Ursachen, Dynamiken und Wege zur Bewältigung
(IU Internationale Hochschule, 2026-01-21) Domguia Teto, Jean Oscard; Dulgeridis, Marcel; Schubart, Constantin
Despite extensive planning, successful strategy implementation remains one of the biggest challenges for organizations worldwide, a phenomenon known as the implementation gap. This thesis systematically analyses the causes of this discrepancy between strategy formulation and realization, ranging from insufficient communication and inadequate resource allocation to organizational resistance to change. Based on a comprehensive literature review of established theories and methods from the fields of Strategic Management, Organizational Development, and Change Management, key success factors for strategy implementation are identified. The core of this work is the development of the “Adaptive Alignment & Execution” (AAX) Framework. This integrative framework combines proven principles and tools to enable a holistic and dynamic approach to strategy implementation. It addresses the need for strategic clarity, dynamic alignment, agile execution, and continuous learning. The framework is supplemented by a practical checklist designed to help organizations proactively address the identified causes of the implementation gap and promote the successful implementation of their strategies.
Social Media als Employer Branding Strategie
(IU Internationale Hochschule, 2026-01-16) Perst, Florian; Schubart, Constantin; Winter, Hannah
The ongoing shortage of skilled workers and the increasing “war for talents” present companies with the challenge of positioning themselves as an attractive employer in order to attract qualified talent. External employer branding activities in social media are increasingly important, particularly with regard to addressing young target groups. The aim of this study is to investigate which external employer branding measures on Instagram and TikTok influence the perception of Generation Y and Z with regard to the attractiveness of a company as an employer. The study is based on a quantitative research design using an online survey as a research instrument. The results of the data analysis indicate that there are differences between Generations Y and Z in terms of content and preferred formats. Generation Y prefers an authentic and informative approach via Instagram that focuses on communicating symbolic attributes. Generation Z, on the other hand, values authentic and humorous insights and the experiential presentation of the employer through instrumental attributes, preferably via Instagram and additionally via TikTok. The implementation of specific activities can have a positive influence on the application intentions of both generations. The findings underline the relevance of a generation-specific approach in order to position oneself as an attractive employer brand on the labor market in the long term.
The Role of Value Alignment in Shaping Employee Engagement Across Generations
(IU International University of Applied Sciences, 2026-01-16) Schubart, Constantin; Meyer, Svenja
This study examined the relationship between employees’ personal work values, their alignment with organizational values, and their effects on employee engagement and turnover intention, with a focus on generational differences. Drawing on the Person-Environment Fit framework, the Job Demands-Resources model, and Self-Determination Theory, the study explored whether value alignment predicts engagement and turnover intention, and whether it mediates the relationship between the two. Data was collected via an online survey from 202 participants across various organizational contexts. Measures included the Utrecht Work Engagement Scale (UWES-9), the Turnover Intention Scale (TIS-6), and an adapted version of the Work Values Survey (WVS). Multiple linear regression and MANOVA were used for hypothesis testing. Results showed that engagement significantly predicted reduced turnover intention, confirming prior research. However, value alignment did not significantly predict engagement or turnover intention, nor did it mediate the relationship between them. Among work values, altruism, prestige, and pay were significantly associated with engagement. No significant generational differences in work values were found, likely due to sample imbalances. The findings suggest that specific work values may influence engagement more than general alignment and highlight the need for refined measurement approaches. Implications for retention strategies, as well as directions for future research on multilevel value alignment and generational diversity, are discussed.
Aufbau eines Digital Learning Space an der IU Internationale Hochschule
(Arbeitsgemeinschaft für Medizinisches Bibliothekswesen (AGMB e.V.), 2025-09-19) Hoffmann, Kira
Digital learning environments can be much more than just platforms for information and communication – they have the potential to evolve into a “third place” where students, educators, and external participants come together to learn from one another and collaboratively develop new ideas. The digital learning space (DLS) at IU International University of Applied Sciences aims to create exactly such a space: a platform that fosters collaborative learning formats, promotes lifelong learning, en hances media literacy, and contributes to a holistic sense of academic wellbeing. This article presents the concept of the digital learning space at IU International University, which is designed around student needs and combines elements of a library, a digital seminar room, and an in tercultural learning environment. The goal is to cultivate a vibrant community that offers both synchronous and asynchronous learning opportunities – from moderated discussions, webinars, and digital project workshops to targeted tutorials and re sources for media and information literacy. This paper will address the following issues: What exactly is a DLS, and how can it support students not only academically, but also in their personal development. What role does a diversity-aware approach play – one that considers different cultural backgrounds and learning styles? And how can such an offering be implemented and sustainably integrated into daily academic life so that it is truly perceived as a third place? The article offers readers a deeper understanding of the technical, conceptual, and didactic aspects of the DLS, along with the key challenges and factors that contributed to its success.
Digitale Lernumgebungen können weit mehr sein als reine Informations- und Austauschplattformen – sie haben das Potenzial, zu einem „Dritten Ort“ heranzuwachsen, an dem Studierende, Lehrende und externe In- teressierte zusammenkommen, voneinander lernen und gemeinsam neue Ideen entwickeln. Der Digital Learning Space (DLS) soll genau diesen Raum bieten: Eine Plattform, die Zugang zu kollaborativen Lernformaten schafft, lebenslanges Lernen fördert, Medienkompetenzen stärkt und so zum ganzheitlichen akademischen Wohlbefinden beiträgt. In diesem Artikel wird das Konzept des Digital Learning Space der IU Internationalen Hochschule vorgestellt, das sich an den Bedürfnissen der Studierenden orientiert und Elemente aus Bibliothek, digitalem Seminarraum sowie interkulturellem Lernort vereint. Dabei soll eine lebendige Community entstehen, in der sowohl synchrone als auch asynchrone Formate angeboten werden: von moderierten Diskussionen, Webinaren und digitalen Projektwerkstätten bis hin zu gezielten Tutorials und Ressourcen zur Medien- und Informations- 1/6GMS Medizin - Bibliothek - Information 2025, Vol. 25(1), ISSN 1865-066X FachbeitragOPEN ACCESSDritter Ort für die Wissenschaft kompetenz. Im Mittelpunkt stehen folgende Fragen: Was ist eigentlich ein DLS und wie kann er Studierende nicht nur fachlich, sondern auch persönlich weiterbringen? Welche Rolle spielt dabei ein diversitätsbewus- ster Ansatz, welcher unterschiedliche kulturelle Hintergründe und Lernstile berücksichtigt? Wie lässt sich ein solches Angebot umsetzen und nachhaltig in den Studienalltag integrieren, um langfristig als Dritter Ort wahrgenommen zu werden? Hier werden Einblicke in die techni- schen, konzeptionellen und didaktischen Überlegungen sowie Heraus- forderungen und Erfolgsfaktoren gegeben.
