Kontinuierliche Evaluation von Nachschulungsprogrammen

Verkehrspsychologische Nachschulungen stellen Maßnahmen zur Rehabilitierung von im Straßenverkehr auffälligen Kraftfahrerlnnen dar. Diese gesetzlich verankerten psychologischen lnterventionsprogramme werden mit hohem Aufwand konzipiert und sind bei der täglichen Durchführung mit beträchtlichen Kosten verbunden. Daraus ergibt sich die Notwendigkeit, die Effektivität der Nachschulungsmodelle durch eine wissenschaftliche Evaluation zu klären. Um die Effektivität der Nachschulungskurse der AAP (Austrian Applied Psychology) zu überprüfen wurde eine Fragebogenstudie mit Pre-Posttest-Designs durchgeführt. Die Ergebnisse der Alkoholkurse zeigen positive Auswirkungen hinsichtlich Einstellungsänderung, spezifischer Selbstwirksamkeitserwartung, interner Attributionen, Wissen und Gesamtbeurteilung

Indirect (implicit) and direct (explicit) self-esteem measures are virtually unrelated: A meta-analysis of the initial preference task.

BACKGROUND:The initial preference task (IPT) is an implicit measure that has featured prominently in the literature and enjoys high popularity because it offers to provide an unobtrusive and objective assessment of self-esteem that is easy to administer. However, its use for self-esteem assessment may be limited because of weak associations with direct personality measures. Moreover, moderator effects of sample- and study-related variables need investigation to determine the value of IPT-based assessments of self-esteem. METHODS:Conventional and grey-literature database searches, as well as screening of reference lists of obtained articles, yielded a total of 105 independent healthy adult samples (N = 17,777) originating from 60 studies. Summary effect estimates and subgroup analyses for potential effect moderators (e.g., administration order, algorithm, rating type) were calculated by means of meta-analytic random- and mixed-effects models. Moreover, we accounted for potential influences of publication year, publication status (published vs. not), and participant sex in a weighted stepwise hierarchical multiple meta-regression. We tested for dissemination bias through six methods. RESULTS:There was no noteworthy correlation between IPT-based implicit and explicit self-esteem (r = .102), indicating conceptual independence of these two constructs. Effects were stronger when the B-algorithm was used for calculation of IPT-scores and the IPT was administered only once, whilst all other moderators did not show significant influences. Regression analyses revealed a somewhat stronger (albeit non-significant) effect for men. Moreover, there was no evidence for dissemination bias or a decline effect, although effects from published studies were numerically somewhat stronger than unpublished effects. DISCUSSION:We show that there is no noteworthy association between IPT-based implicit and explicit self-esteem, which is broadly consistent with dual-process models of implicit and explicit evaluations on the one hand, but also casts doubt on the suitability of the IPT for the assessment of implicit self-esteem on the other hand

Architecting service-dominant digital products

Presently, many companies are transforming their strategy and product base, as well as their culture, processes and information systems to become more digital or to approach for a digital leadership. In the last years new business opportunities appeared using the potential of the Internet and related digital technologies, like Internet of Things, services computing, cloud computing, edge and fog computing, social networks, big data with analytics, mobile systems, collaboration networks, and cyber physical systems. Digitization fosters the development of IT environments with many rather small and distributed structures, like the Internet of Things, Microservices, or other micro-granular elements. This has a strong impact for architecting digital services and products. The change from a closed-world modeling perspective to more flexible open-world composition and evolution of micro-granular system architectures defines the moving context for adaptable systems. We are focusing on a continuous bottom-up integration of micro-granular architectures for a huge amount of dynamically growing systems and services, as part of a new digital enterprise architecture for service dominant digital products
