Nous nous sommes demandés, dans cette étude, si les groupes étaient mieux à même de respecter les délais quand leurs membres partageaient les mêmes cognitions temporelles, c'est-à-dire quand ils s'accordaient sur les dimensions temporelles de leur tâche. Dans une étude longitudinale portant sur 31 groupes, nous avons étudié l'effet des cognitions temporelles partagées sur le respect d'un délai et exploré deux antécédents des cognitions temporelles partagées: la cohérence des rythmes des membres du groupe et l'échange des rappels concernant le temps. Nos résultats montrent que ces deux facteurs ont un impact sur les cognitions temporelles partagées et cela à différentes étapes du travail collectif. De plus, il est apparu que les cognitions temporelles partagées pouvaient aussi bien faciliter que contrecarrer le respect des délais: cela dépend des rythmes des membres du groupe.In this study, we examined whether groups were better able to meet deadlines when group members had shared temporal cognitions, that is, when they agreed on the temporal aspects of their task. In a longitudinal study involving 31 groups, we studied the effect of shared temporal cognitions on meeting a deadline and explored two antecedents of shared temporal cognitions: the similarity in group members' pacing styles and the exchange of temporal reminders. Our findings suggest that both antecedents are relevant to shared temporal cognitions, be it at different stages of group collaboration. Furthermore, we found that shared temporal cognitions may either facilitate or impede meeting a deadline, depending on the content of group members' pacing styles.

Which factors explain intra‐ and inter‐country variations in levels of public support for national health care systems within the European Union, and why? We propose that public opinion towards public health care is dependent on (1) the type of welfare state regime to which the various European welfare states belong, (2) typical features of the national care system and (3) individual social and demographic characteristics, which are related to self‐interest or morality oriented motives. To assess the explanatory power of these factors, data from the Eurobarometer survey series are analysed. Support for public health care appears to be particularly positively related to social‐democratic attributes of welfare states, whereas support drops with increasing degrees of liberalism and conservatism. Further, support for public health care proves to be associated with wider coverage and public funding of national care services. We also find higher levels of support in countries with scarce social services for children and the elderly, and larger proportions of female (part‐time) employment. Lastly, with respect to individual characteristics, we find remarkably little evidence for self‐interest oriented motives affecting the preference for solidary health care arrangements.

SummaryIn this study of 43 student project teams, we tested a multi-level mediation model of the relationship between dissimilarity in conscientiousness, team temporal processes, and team member satisfaction. We distinguished between individual-level dissimilarity in conscientiousness (i.e., the distance between an individual member and his or her team mates), and team-level dissimilarity in conscientiousness (i.e., the overall dissimilarity within the team). Individual-level dissimilarity in conscientiousness had a direct negative effect on team members' satisfaction with the team, but did not affect their satisfaction with the team's performance. Team-level dissimilarity in conscientiousness indirectly affected both types of satisfaction negatively as it impeded early agreement about the temporal aspects of task execution, which, in turn, hindered coordinated action in later stages of team task execution.
