Understanding excessive sleep in people with psychotic disorders
British Journal of Clinical Psychology, EarlyView.Abstract Background There has been increasing attention to sleep disturbances such as insomnia in psychosis, due to its impact on symptoms, well‐being, and recovery. However, excessive sleep and extended sleep duration are common in psychosis (partly linked to sedating antipsychotic medication) and have been relatively neglected, despite plausible ...

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Multi-mesh gear dynamics program evaluation and enhancements [PDF]
A multiple mesh gear dynamics computer program was continually developed and modified during the last four years. The program can handle epicyclic gear systems as well as single mesh systems with internal, buttress, or helical tooth forms.

Journal of Management Studies, EarlyView.Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Nations and Nationalism, EarlyView.ABSTRACT The revival of Biafran separatism in contemporary Nigeria is often explained with three leading theoretical frameworks: relative deprivation, political economy and state repression. Whereas relative deprivation and political economy perspectives posit that the resurgent separatism derives from the perception and empirical reality of ...
