IDIMT-2025 : ICT in Business : AI Everywhere? Glory and Disgrace of AI : 33rd Interdisciplinary Information Management Talks Sept. 3–5, 2025 Hradec Králové, Czech Republic / von Petr, Doucek / Structured insights into green procurement: The Lithuanian case
No full textGreen public procurement (GPP) represents a key policy instrument for promoting environmental sustainability through public sector spending. This study conducts a data-driven assessment of green procurement practices in Lithuania using publicly available procurement data accessed through the
national Power BI dashboard. The analysis distinguishes between high-value and low-value green contracts (above and below € 60,000, respectively), exploring the distribution of procurement by contract type (works, services, goods), CPV (Common Procurement Vocabulary) categories, and the
application of specific environmental clauses. A Pareto analysis identifies the CPV categories that dominate the volume of green tenders, while a clause-level breakdown reveals how environmental criteria are most frequently integrated into procurement documentation (e.g., technical specifications, supplier qualifications, and contract performance conditions). The findings show that in high-value contracts, the top CPV categories account for over 80% of green procurement volume, with environmental management requirements and self-determined environmental criteria being the
most widely used clauses, particularly in works and services contracts
IDIMT-2025 : ICT in Business : AI Everywhere? Glory and Disgrace of AI : 33rd Interdisciplinary Information Management Talks Sept. 3–5, 2025 Hradec Králové, Czech Republic / von Petr, Doucek / AI-supported decision-making in the outsourcing of internal logistics processes
No full textThis paper examines how artificial intelligence (AI) can support decision-making in the outsourcing of internal logistics services. Based on a case study of Ford Trans Slovakia, the research compares traditional supplier evaluation methods with AI-enhanced multi-criteria decision-making (MCDM) models. The study specifically integrates predictive analytics with the Analytic Hierarchy Process (AI-AHP) and a Forced Decision-Making Matrix (AI-FDMM) to assess potential logistics providers. Findings highlight improved accuracy in supplier ranking, early risk detection, and better alignment with strategic goals. The results demonstrate that AI tools significantly reduce managerial subjectivity and enhance the predictive quality of decisions. The paper concludes by recommending the adoption of hybrid decision-making models that combine AI capabilities with expert insights, as well as investments in data infrastructure to ensure long-term competitiveness

Glory and Disgrace of AI : 33rd Interdisciplinary Information Management Talks Sept. 3–5, 2025 Hradec Králové, Czech Republic / von Petr, Doucek / Integration of education aimed at developing the knowledge and skills of the student reflecting the requirements of the 21st century
No full textThe paper points to future trends in skills needed for individuals in order to successfully find employment in the labor market among competitors. The aim of the paper is to give, if possible, an overview of the basic development areas of education, which have been published by experts in
important studies and surveys published so far and which can facilitate the entry of graduates into the labor market. The skills and abilities of students needed for practice help develop activities such as graduate internships and team projects organized in cooperation between universities and businesses. The basics of project and process management give students valuable experience and skills to practice within a safe academic space what they will use in their future lives. Working on projects requires teamwork, analytical thinking and a sense of innovation, a comprehensive assessment of the issue, analysis and critical thinking, creativity and originality, knowledge of the use of technology, reasoning, problem-solving and imagination, as well as resilience, stress tolerance and flexibility, empathy. These are all qualities that employers require from employees not only today, but also in the foreseeable future
The dynamics between organizational practice and digital technologies - on the introduction of artificial intelligence in health insurance companies
No full textDiese Arbeit entwickelt den konzeptionellen Beitrag Sensemaking als transversale Praxis zu verstehen anhand einer Einzelfallstudie zur Einführung und Nutzung Künstlicher Intelligenz in einer deutschsprachigen Krankenversicherung. Sie trägt damit zur soziologischen Debatte zur Einführung und Nutzung von (digitalen) Technologien in Organisationen bei, indem ein Erklärungsangebot für die Transformation organisationaler Praktiken entwickelt wird, welche vor allem durch Sensemaking als transversale - zu den organisationalen Praktiken querliegende - Praxis verstanden wird. Anhand der Kombination verschiedener qualitativer Methoden wird aufgezeigt, wie sich die für die Sachbearbeiter*innen zentrale Logik „schöner Fälle“ durch gegenüber anderen Akteursgruppen behauptete Sinnstiftungen auf die weitere Entwicklung des KI-Systems auswirken. Dabei besteht ein Wechselverhältnis, da sich diese Änderungen an der Technik wieder auf die organisationalen Praxis in ihren Wissens-, Materialitäts- und Anerkennungsdimensionen auswirkt im Vollzug der alltäglichen Praxis. Damit reiht sich diese Arbeit in soziologische Debatten um die Einführung und Nutzung von Technik in Organisationen ein, aber auch um die soziologische Auseinandersetzung um Künstliche Intelligenz als einer spezifischen Technologie.This dissertation develops the conceptual contribution of sensemaking as a transversal practice through a single case study on the introduction and use of artificial intelligence in a German-speaking health insurance company. It contributes to the sociological debate on the introduction and use of (digital) technologies in organizations by providing an explanatory framework for the transformation of organizational practices, which is primarily understood through sensemaking as a transversal practice that intersects with organizational practices. Using a combination of various qualitative methods, the study illustrates how the central logic of "beautiful cases" for caseworkers, shaped by the sense-making asserted against other actor groups, influences the further development of the AI system. There is a reciprocal relationship, as these changes in technology also impact organizational practice in its dimensions of knowledge, materiality, and recognition in the course of everyday practice. Thus, this work aligns with sociological debates about the introduction and use of technology in organizations, as well as the sociological discourse surrounding artificial intelligence as a specific technology.Eingereicht von René WernerAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersDissertation Johannes Kepler Universität Linz 202
How abusive supervision affects creativity - a review
No full textThis thesis presents a systematic literature review to examine the impact of abusive supervision on employee creativity. It concentrates on mediating and moderating mechanisms and analyzes 28 peer-reviewed empirical studies. This provides a deeper understanding of how abusive supervisors influence creative performance through emotional, cognitive, behavioral, and organizational pathways.
According to the findings, abusive supervision is most often linked to a decrease in employee creativity due to negative emotions such as emotional exhaustion or anger. As a result of these feelings, employees become less motivated, cognitively flexible, and willing to take risks. However, the analysis also shows that abusive supervision does not always lead to negative outcomes. Instead, individual creativity may even be boosted in certain situations, such as when anxiety or strong extrinsic motivation are present. This thesis suggests that the effects of abusive supervision heavily depend on individual characteristics and contextual factors. There is no single reason why abusive supervision reduces employee creativity. Instead, it influences creative performance through various psychological, cognitive, and contextual pathways, both positively and negatively.
A variety of theoretical frameworks—such as conservation of resources theory (COR), affective events theory (AET), and social exchange theory (SET)—that have been applied across the sample are discussed. By considering these theories, it is possible to put the findings into perspective, gain a deeper understanding of the relationship between abusive leadership, employee creativity, and various mechanisms, as well as provide a direction for future research and organizational interventions.Author Engi El-Husseini, LL.B.Masterarbeit Johannes Kepler Universität Linz 202

No full textDer Nimbus der Innovation : eine Einzelfallstudie zu den Effekten eines Pilotversuchs zur Wirtschaftsbildung an Schulen
No full textDiese Masterarbeit untersucht, wie der Innovationsnimbus, die besondere Wahrnehmung neuer Bildungsinitiativen, die Unterrichtsqualität im Rahmen des österreichischen Schulpiloten der Stiftung Wirtschaftsbildung beeinflusst. Anhand einer qualitativen Einzelfallstudie an der Technisch Naturwissenschaftlichen Mittelschule Helfenberg wird der Wirtschaftsbildungsunterricht mit dem regulären Fach Geografie und wirtschaftliche Bildung verglichen. Grundlage der Datenerhebung waren teilnehmende Unterrichtsbeobachtungen über fünf Monate sowie halbstrukturierte Interviews mit einer Lehrkraft und zwanzig Schülerinnen und Schülern. Für die Auswertung der Daten wurde die qualitativer Inhaltsanalyse nach KUCKARTZ & RÄDIKER (2024) angewandt und mithilfe der Software MAXQDA (VERBI SOFTWARE, 2024) eingesetzt.
Die Ergebnisse zeigen, dass der Innovationsnimbus positive Effekte auf einzelne Qualitätsmerkmale nach HELMKE (2021) entfalten kann. Entscheidend ist jedoch das Zusammenspiel materieller Faktoren (z. B. hochwertiges Unterrichtsmaterial oder günstige zeitliche Rahmenbedingungen) und im-materielle Faktoren (z. B. Lebensweltbezug und Partizipationsmöglichkeiten). Fehlen diese Ressourcen oder werden sie von den Beteiligten negativ wahrgenommen, verpufft der anfängliche Innovationsimpuls und kann sogar demotivierende Effekte haben. Umgekehrt können sich materielle und immaterielle Faktoren gegenseitig positiv beeinflussen.
Die Arbeit leistet einen Beitrag zur fachdidaktischen Diskussion um die Implementierung innovativer Bildungsprogramme, indem sie zeigt, dass nachhaltige Qualitätsverbesserungen nicht allein durch neue Inhalte oder organisatorische Änderungen entstehen. Vielmehr sind passgenaue materielle Unterstützung, förderliche Rahmenbedingungen und eine gelebte Innovationskultur entscheidend. Für die Praxis bedeutet dies, dass Pilotprojekte nur dann langfristig Wirkung entfalten, wenn sie sowohl strukturell absichern als auch im schulischen Alltag positiv verankert sind.This master’s thesis examines how the aura of innovation, the special perception of new educational initiatives, influences the quality of teaching within the context of the Austrian school pilot project of the Stiftung Wirtschaftsbildung. Using a qualitative single-case study at the Technisch Naturwissenschaftliche Mittelschule Helfenberg, Economics Education lessons were compared with the regular subject Geography and Economic Education. Data collection was based on five months of participant classroom observations as well as semi-structured interviews with one teacher and twenty students. The analysis was conducted using qualitative content analysis according to KUCKARTZ & RÄDIKER (2024) with the support of the software MAXQDA (VERBI SOFTWARE, 2024).
The findings indicate that the aura of innovation can have positive effects on specific quality indicators of good teaching as defined by HELMKE (2021). However, the interaction between material factors (e.g., high-quality teaching materials or favorable time frames) and immaterial factors (e.g., relevance to student’s everyday lives and opportunities for participation). If these resources are lacking or perceived negatively by those involved, the initial innovation impulse dissipates and can even have demotivating effects. Conversely, material and immaterial factors can have a positive influence on each other.
The work contributes to the subject-specific didactic discourse on implementing innovative educational programs by showing that sustainable improvements in teaching quality do not arise solely from new content or organizational changes. Rather, tailored material support, conducive framework conditions and a lived culture of innovation are crucial. In practice, this means that pilot projects can only achieve lasting impact if they are both structurally secures and positively embedded in everyday school life.Eingereicht von Verena KaiserMasterarbeit Johannes Kepler Universität Linz 202
European Journal of Organic Chemistry / Determination of the pKaHof Established Isothiourea Catalysts
No full textAbstract Isothioureas (ITUs) represent a powerful family of (chiral) Lewis base organocatalysts. Interestingly, the Brønsted basicity of these frequently used compounds has so far not systematically been investigated. Thus, we have now determined the p K aH values of the most privileged (chiral) ITUs in acetonitrile (ACN) and DMSO by using NMR. Employing Wallace's chemical shift imaging NMR method, the herein investigated ITUs were found to be weak Brønsted bases with p K aH values in the range of 16.8–17.9 in ACN and 6.3–7.8 in DMSO
