Sleep deprivation is well known to negatively affect mood, cognition and behaviour. The purpose of this paper is to explore the relationship between sleep quantity, subjective sleep quality and aggression, hostility and well-being levels among adults in a non-clinical population.

In total, 201 participants aged 18 and above from Germany, UK and the Netherlands completed an online survey consisting of a Pittsburgh Sleep Quality Index along with measures of psychological well-being, implicit and explicit aggression, and intent attributions.

Sleep disturbances were related to decreased levels of psychological well-being. Subjective poor sleep quality predicted increased hostile attributions. The overall sleep experience, however, was not associated with aggression levels. Nevertheless, both a poor sleep experience and low sleep quality were related to increased reactive aggression, but only in British participants.

The importance of perceived sleep quality rather than sleep quantity in predicting hostile and aggressive behaviours is indicated. The quality of sleep and perception of this quality should be the focus of clinical intervention to limit unwanted behavioural impacts. The importance of accounting for sleep quality perception in intervention that examines attributional biases such as hostility is indicated. Differences across countries should be identified and accommodated for in intervention.

This is the first study to consider a role for sleep quality (including perception) and sleep quantity in relation to aggression and hostility in a cross-country European sample.

Extant literature has looked at the effect of alliance capability and organizational culture on alliance portfolio performance, but the relationship between the two has not been explored. The purpose of this paper is to explore the hypothesis that an alliance supportive culture is not only fostered by a firm’s alliance capabilities, but that it mediates the relationship between capabilities and performance.

Survey responses from 190 alliance managers, collected using a two-stage process, were analyzed to investigate the interrelationship of firm-level alliance capability, alliance supportive culture and portfolio performance.

Alliance supportive culture was found to mediate the relationship between alliance capability and alliance portfolio performance. This finding suggests that in order to effectively manage a firm’s portfolio of alliances, the benefits of alliance capability must be transferred broadly into the organization’s cultural orientation toward alliances.

Further research may extend this analysis to explore the effect of subcomponents of alliance capability and alliance culture to better understand fine-grained influences on alliance performance. The findings of this study also may be extended to inform how supportive culture orientation affects partner selection, negotiation and time to performance.

Managers should utilize culture-building actions as a way of extending the value of their firms’ alliance capabilities in order to improve their effectiveness across the portfolio.

Extant studies have considered the discrete effects of capability and cultural orientation on alliance portfolio success, but the mediation effect has not previously been investigated. The findings also identify a boundary condition for the benefit of alliance capabilities on portfolio performance.

This paper aims to understand technology-based accelerators’ legitimation efforts in an emerging entrepreneurship ecosystem.

This research is based on qualitative inductive methodology using ten Turkish technology-based accelerators.

The analysis indicates that accelerators’ legitimation efforts are shaped around crafting a distinctive identity and mobilizing allies around this identity; and establishing new collaborations to enable collective action. Further, the authors observe two types of technology-based accelerators, namely, “deal flow makers” and “welfare stimulators” in Turkey. These variations among accelerators affect how they build their legitimacy. Different types of accelerators make alliances with different actors in the entrepreneurship ecosystem. Accelerators take collective action to build a collective identity and simultaneously imply how they are distinguished from other organizations in the same category and the ones in the old category.

This study presents a framework to understand how accelerators use strategies and actions to legitimize themselves as new organizations and advocate new norms, values and routines in an emerging entrepreneurship ecosystem. The framework also highlights how different accelerators support legitimacy building by managing the judgments of diverse audiences and increasing the variety of resources these audiences provide to the ecosystem.
