The management revue is a peer-reviewed interdisciplinary European journal publishing both qualitative and quantitative work as well as purely theoretical papers that advance the study of management, organisation and industrial relations. The management revue publishes articles that contribute to theory from a number of disciplines, including business and public administration, organizational behavior, economics, sociology and psychology. Reviews of books relevant to management and organisation studies are a regular feature. Special issues provide a unique and rich insight into the issue's research field. The journal offers insights into selected research topics by providing potentially controversial perspectives, new theoretical insights, valuable empirical analyses and brief reviews of key publications. The aim is to establish the management revue as a top quality symposium journal for the international academic community. The journal is available online via the Nomos eLibrary, ABI/INFORM Global and JSTOR. The management revue is indexed in the Web of Science™ Emerging Sources Citation Index (ESCI), Elesevier's Scopus and the RePEc services IDEAS and EconPapers.

The energetic state before the start of work has been associated with work-related outcomes (e.g. job performance). However, little is known regarding the determinants of the energetic state before starting work. It can be assumed that working parents, in particular, face various resource-consuming demands (e.g. childcare-related demands) before they start working that may impact the subsequent workday. To test this assumption, we conducted a diary study involving 130 working parents over five workdays. We investigated the effects of childcare-related and commute-related demands as predictors of changes in fatigue between awakening and starting work. Furthermore, we examined the mediated effect of morning demands on job performance via start-of-work-time fatigue. Finally, we investigated whether work schedule flexibility and childcare drop-off time flexibility attenuated the adverse effect of morning demands on fatigue. The results indicated that morning childcare-related and commute-related demands had a significant indirect effect on job performance, as these morning demands predicted start-of-work-time fatigue, which in turn was associated with daily job performance. Work schedule flexibility, but not drop-off time flexibility, buffered the effect of morning demands on start-of-work-time fatigue. To enhance the job performance of working parents, future research should pay more attention to contextual factors before daily work starts.

Zusammenfassung. Die Gemeinsame Deutsche Arbeitsschutzstrategie (GDA) empfiehlt in ihrer Leitlinie eine Liste psychischer Belastungsfaktoren, die bei der Gefährdungsbeurteilung berücksichtigt werden sollen. Der vorliegende Artikel stellt den Fragebogen zur Gefährdungsbeurteilung psychischer Belastungen (FGBU) vor, der das Ziel hat, die dort genannten Belastungsfaktoren reliabel und valide zu messen. Der Fragebogen beinhaltet 19 Skalen sowie einen Index mit zehn Umgebungsbelastungen. Er wurde in drei Studien mit einer Gesamtstichprobe von 1203 erwerbstätigen Personen mit unterschiedlichen Arbeitstätigkeiten getestet. Die Ergebnisse von Item- und Skalenanalysen bestätigen die gute Messqualität der eingesetzten Skalen. Zusammenhangsanalysen zur Prüfung der inhaltlichen, kriteriumsbezogenen und inkrementellen Validität deuten darauf hin, dass der neu entwickelte Fragebogen die zu erfassenden psychischen Belastungen valide misst. Zudem bestätigen die Ergebnisse des Einsatzes des Fragebogens in zwei Betrieben die praktische Nutzbarkeit des Fragebogens sowie die Möglichkeit, Ergebnisse von organisatorischen Einheiten zu aggregieren. Der Fragebogen ist gut geeignet, um im Rahmen von Gefährdungsbeurteilungen die von der GDA vorgeschlagenen Belastungsfaktoren mit gut überprüften und zugleich ökonomischen Skalen in ihrer Gesamtheit zu erfassen.

The study demands–resources framework states that study demands increase exhaustion and study resources increase engagement. Study crafting describes a student's proactive adaption to demands and resources. To date, no intervention in the higher education context has aimed to foster study crafting. Accordingly, this study developed and evaluated the STUDYCoach online intervention, which aimed to increase engagement and reduce exhaustion by promoting study crafting. The study was a randomized controlled trial with a waiting‐list control group. All participants ( N = 209) completed a questionnaire before (T1) and after (T2) the intervention and at a 20‐week follow‐up (T3). Participants in the intervention group ( n = 149) used the STUDYCoach over three consecutive weeks. Results showed that overall study crafting, decreasing hindering demands, and engagement significantly increased in the intervention group compared to the control group after the intervention. All effects remained stable at follow‐up. Notably, exhaustion decreased significantly in the intervention group from T1 to T3 and T2 to T3. Study crafting mediated the intervention's effect on engagement and exhaustion. Our study extends the study demands–resources framework and the literature on job crafting by confirming that study crafting interventions can be effective in higher education.

Leaders influence their followers directly through interactions and role modelling, and indirectly by providing resources and managing demands. However, to lead accordingly, leaders require adequate working conditions. So far, little is known about the contextual antecedents of leadership and its subsequent impact on follower job characteristics. To address this research question, we asked 711 employees and their 82 direct leaders about their autonomy and their workload at three points of time (time lags: 12–14 months between T1 and T2 and 6–7 months between T2 and T3). Followers also rated their leaders on transformational leadership. The analysis accounted for the nested data structure. Results showed that leader autonomy and workload are linked to transformational leadership behaviour, which is significantly related to follower autonomy but not follower workload. The findings of this longitudinal study highlight the importance of leader job characteristics for establishing transformational leadership behaviours and designing their followers’ job characteristics.
