The great revolutionary and philosopher Thomas Paine wrote on the eve of the American Revolution in 1776 that "these are the times that try men’s souls." He might as well have been talking about the global challenges mankind faces today.The latest edition in the two-decade annual series of the globally fielded Edelman Trust Barometer(ETB),an annual survey of trust and credibility in four major institutions—government,business,media and non-governmental organizations,provides some answers to which nations are meeting today’s existential challenges.And which are not.  相似文献

From blaming to helping innocent victims, just-world research has revealed that observers react to victimization in a variety of ways. Recent research suggests that such responses to victimization require effortful thought, whereas other research has shown that people can react to these situations intuitively. Along with manipulating just-world threat, across seven experiments, we manipulated or measured participants’ level of mental processing before assessing judgments of victim derogation, blame, willingness to help, and ultimate justice reasoning. The effect of just-world threat on these responses held constant over a range of manipulations/measures, suggesting that the processes involved in maintaining a belief in a just world are not restricted to the rational, deliberative level of mental processing but also occur intuitively.  相似文献

Most adolescents face numerous obstacles to good sleep, which may undermine healthy development. In this study, we used latent class analysis and identified four categories of sleep barriers in a diverse sample of 553 urban youth (57% female). The majority profile, School/Screens Barriers, reported the most homework and extracurricular barriers, along with high screen time. The Home/Screens Barriers class (i.e., high environmental noise, light, screen use) and the High/Social Barriers class (i.e., high barriers across domains, particularly social) reported the poorest sleep quality and highest depressive/anxiety symptoms. The Minimal Barriers class—predominately male, with low depressive/anxiety symptoms—reported more sleep per night. We discuss implications of our findings for targeting interventions to address poor adolescent sleep among specific clusters of students.  相似文献

This study investigates the relationship between knowledge-sharing mechanisms, managerial tacit knowledge, and individual performance in the Malaysian public sector. Moderation effects of employee personality on these variables were also examined. Findings from 308 Malaysian public sector managers suggest that individual performance is influenced by levels of accumulated managerial tacit knowledge (LAMTK), which were moderated by employee personality traits. The findings also show that individual performance has an impact on the effectiveness of knowledge-sharing mechanisms.  相似文献

Developing strong, policy-relevant causal explanations for major events in world politics often requires identification and rejection of weak counterfactual claims. Poorly constructed counterfactual arguments reveal serious deficiencies that undercut the necessary condition theories from which they are derived. Stronger explanations of historical events emerge when these weaknesses are weighed against the strengths of competing counterfactuals. Comparing the relative plausibility of competing (weak versus strong) counterfactual claims about the same event is the essence of comparative counterfactual analysis (CCA). When combined with process tracing, CCA can help to generate policy relevant findings by resolving many of the methodological pitfalls researchers confront when each method is applied in isolation.  相似文献

Abstract

The paper raises issues of analysis and policy for science and technology in developing countries within the global context of the post-genomic era. Based on a case study of a newly created Brazilian research and technology capability, it argues for an understanding of variety creation, where new organizational forms often transgress established scientific and organizational boundaries and arrangements. In particular, new frontiers of science and technology can be opened up by the alternative trajectories generated by differences in socio-economic, institutional and ecological conditions in ways that thereby reinforce those very differences. It stresses the inherent unevenness and heterogeneity of innovation processes. By focusing on the geopolitical significance of diverse pathways of science and innovation, the approach suggests an alternative vision to catch-up models of innovation and development in terms of variety creation.  相似文献
