Zwischen Realität und Fantasiewelt: Die psychologischen Wirkungen immersiver Freizeitparkgestaltung auf Konsumentscheidungen
(IU Discussion Papers, 2026-02-21) Schümann, Jakob; Weege, Maria
Amusement parks are more popular than ever in Germany, transporting their guests into artificial worlds that tell their own stories. Theming and storytelling are an integral part of the holistic experience in many parks and inevitably have an effect on visitors. Nevertheless, there is a lack of scientific understanding of the psychological effects triggered by immersive amusement park design and how it influences consumer behavior. This work therefore aims to explore the psychological effects of immersive amusement park design and its influence on the choice of the amusement park visited. To this end, 115 people who had visited at least one amusement park in the past three years were asked about their subjective feelings during their visit in an online survey. The research revealed that aesthetic amusement park design triggers positive emotions, which in turn appear to promote customer loyalty. The immersion experienced during the visit promotes flow states, can satisfy social needs and the need to escape from everyday life, and is a relevant decision-making criterion when choosing an amusement park. These findings can help amusement parks make strategic investment decisions and form the basis for further research in this field.
Die Psychologie der Karriereentwicklung: Wie beeinflussen psychologische Konstrukte beruflichen Erfolg und Misserfolg?

In a changing world of work, career success is no longer determined solely by objective criteria such as salary or promotion, but increasingly by subjective evaluations such as job satisfaction, personal goal attainment, and self-fulfillment. Against this background, the concept of subjective career success and failure has gained growing attention. The present study examined the influence of selected psychological constructs - self-efficacy, learning goal orientation, self-doubt and maladaptive perfectionism - on the subjective experience of career success or failure among employed individuals. It was hypothesized that self-efficacy and learning goal orientation are positively related to subjective professional success, while self-doubt and maladaptive perfectionism are positively associated with subjective career failure. The results largely confirm these assumptions: Self-efficacy showed a significant positive correlation with subjective career success, while both self-doubt and maladaptive perfectionism were significant predictors of subjective career failure. No significant correlation was found between learning goal orientation and subjective career success. The findings underline the relevance of psychological constructs for the subjective experience of career success and failure and provide initial indications of potential starting points for promoting occupational self-efficacy as well as for preventive approaches to dealing with self-doubt and maladaptive perfectionism.
Bibliothek ohne Wände: Mein erstes Jahr als Academic Liaison Librarian in einer virtuellen Hochschulbibliothek
(Hochschule für Angewandte Wissenschaften Hamburg (HAW Hamburg), 2026-02-11) Hoffmann, Kira
Der Artikel beschreibt das erste Berufsjahr der Autorin nach dem Masterabschluss in Bibliotheks- und Informationswissenschaft mit der Profillinie Bibliothekspädagogik an der HTWK Leipzig. Ich arbeite heute als Academic Liaison Librarian an der IU Internationale Hochschule, deren Bibliothek vollständig virtuell arbeitet und mehr als 130.000 Studierende betreut. In meinem Erfahrungsbericht gebe ich Einblicke in meine Aufgabenbereiche, darunter die Entwicklung von KI-Sprechstunden, digitalen Schulungen und virtuellen Lernräumen sowie Qualitätsmanagement und Studierendenzufriedenheit. Dabei zeige ich, wie ich meine bibliothekspädagogischen Kenntnisse in der Praxis einsetze und welche Chancen und Herausforderungen sich durch die Arbeit in einem vollständig digitalen Umfeld ergeben.
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.
