Item type:Item, A preliminary analysis of the psychometric properties of the German O*NET interest profiler short form in rehabilitation education(Frontiers Media SA, 2026-08-20) Wild, Steffen; Möhring, MichélleInterest is a key driver of performances, decisions and choices, for example starting an educational program. The German O*NET Interest Profiler Short Form is a recent RIASEC-based instrument. However, its evidence is limited in German speaking subpopulation. We analyze its psychometric properties in N = 173 students from rehabilitation education programs. Internal consistency is adequate in all six scales (ω = .80–.90) and structural validity shows partial support for the RIASEC circumplex. Intercorrelations follow the expected pattern only partly and multidimensional scaling indicate a good overall fit (RSQ = .94; stress ≈.11), although deviations from a perfect hexagonal is observed. Discriminant validity is supported by generally small-to-medium associations with Big Five traits below the discriminant threshold (r < .85). Criterion-related validity is weak. Using Euclidean distance for congruence analysis, associations with study satisfaction (r = −.08, −.09) and dropout intention (r = .06) are near zero. Using angular agreement for congruence analysis, small but statistically significant correlations exist for study satisfaction (r = .17–.18, p < .05). In summary, results show partial evidence for structural validity, clear support for discriminant validity, and limited criterion-related validity. Findings further suggest that conclusions about validity depend on sample characteristics and the chosen operationalization of vocational interest congruence.Item type:Item, Exploring the multifaceted Dbf4-dependent kinase from temporal, spatial, and substrate repertoire perspectives(Springer Science and Business Media LLC, 2026-06-23) Galanti, Lorenzo; Pfander, BorisThe Dbf4‑dependent kinase (DDK), composed of the catalytic subunit Cdc7 and the regulatory subunit Dbf4, is a serine/threonine kinase traditionally defined as an essential activator of DNA replication. Here, we review DDK function from three complementary perspectives: its temporal regulation during the cell cycle, its spatial organization on chromosomes, and its expanding substrate repertoire. These perspectives reveal that DDK acts beyond DNA replication, targeting proteins involved in chromosome segregation, DNA damage responses and homologous recombination. Together, they redefine DDK as multifunctional genome integrity kinase which coordinates cell cycle progression and genome stability offering a unique therapeutic potential in cancer therapy.Item type:Item, Probabilistic modelling of material properties based on structural design and testing standards and its impact on the assessment of structural service life(Springer Science and Business Media LLC, 2026-03-19) Faghfouri, Saeideh; Feiri, Tânia; Ricker, Marcus; Strauss, AlfredThe reliability of engineering structures and infrastructure is a critical requirement to ensure a continuous functionality throughout their expected service life. The lifespan extension of concrete structures—especially those belonging to critical infrastructure—is vital to the sustainability and resilience of the whole built environment. This investigation explores the potential to extend the service lifetime of concrete structures by considering the role of modern design codes and conformity standards on concrete production in combination with reliability-based safety concepts applied to the resistance side. The study demonstrates how evaluation criteria derived from empirical concrete samples influence the service life of structures and, in consequence, the safety format established in international codes. The results suggest that by considering measures of concrete variability—as the coefficients of variation—and integrating them into a quality control system, hidden safety margins can be identified and, ultimately, activated to extend the service lifetime of structures. Therefore, this investigation contributes to the sustainable development of infrastructure ensuring that future demands on infrastructure can be met while maintaining high safety standards.Item type:Item, Soziologische Modellierung nachhaltiger Transformation(2026) Philipp, Marlon; Weyer, Johannes; Sommer, BerndDie Dissertation untersucht am Beispiel des Ruhrgebiets, wie eine nachhaltige Transformation des Mobilitätssektors sozialwissenschaftlich analysiert und gestaltet werden kann. Hierzu wird ein soziologisches Modell nachhaltiger Transformation (SMNT) entwickelt, das bestehende Nachhaltigkeits- und Transformationsmodelle in einem Mehrebenenansatz integriert. Eine Literaturanalyse zeigt, dass der deutsche Mobilitätssektor zentrale Nachhaltigkeitsziele verfehlt. Im empirischen Teil werden die Ergebnisse einer Befragung von 10.782 Universitätsangehörigen im Ruhrgebiet in die agentenbasierte Verkehrssimulation (MATSim) integriert. Die Befragung zeigt eine Diskrepanz zwischen der Nutzung des öffentlichen Verkehrs und den Präferenzen für individuelle Mobilität; zudem werden fünf Akteurstypen identifiziert. Mittels der Simulation werden fünf nachhaltige Governance-Optionen analysiert. Die Ergebnisse zeigen, dass insbesondere eine Steigerung des Fahrradkomforts sowohl die soziale als auch die ökologische Nachhaltigkeit verbessern kann.Item type:Item, Amtliche Mitteilungen der Technischen Universität Dortmund Nr. 20/2026(Technische Universität Dortmund, 2026-09-22)
