Recent research linking individuals' personality characteristics to their social networks has brought a new understanding of how individual patterns of behavior affect networks in organizations. This review summarizes the major advancements in the three areas of social network research relevant to organizational behavior: (a) brokerage and structural holes; (b) network centrality and network size; and (c) strength of ties. This review also provides an agenda outlining three key opportunities for future research. These opportunities involve personality and social network change, bidirectional and dyadic processes, and the potential effect of network position on personality expression.

The undermining effect revisited: The salience of everyday verbal rewards and self‐determined motivation

Self‐determination theory suggests that some rewards can undermine autonomous motivation and related positive outcomes. Key to this undermining is the extent to which rewards are perceived as salient in a given situation; when this is the case, individuals tend to attribute their behavior to the incentive, and the intrinsic value of the task is undermined. The role of salience has yet to be explicitly tested with respect to work motivation; we know little about whether undermining occurs in relation to verbal rewards, which characterize everyday work. We examine this in a field‐based quantitative diary study of 58 employees reporting 287 critical incidents of motivated behavior. When considering simple direct effects, the undermining effect was not supported; highly salient verbal rewards associated positively with introjected and external motivation, but at no cost to autonomous motivation. However, moderator analysis found support for the undermining effect for complex tasks; highly salient verbal rewards associated positively with external motivation while associating negatively with intrinsic and identified motivation. The findings suggest that verbal reward salience is an important characteristic of verbal reward perceptions and that salient verbal rewards are not advisable for more complex tasks but can have a valuable motivational impact for simple tasks.

To make the case that theory is a necessary part of research in the organization sciences, I develop three lines of argument. In the first, drawing upon Staw and Sutton's (1995, “What theory is not” Administrative Science Quarterly, 40, 371–384) classic piece, I outline the boundaries of theory and, using a recently published empirical article as an example, demonstrate how research based on literature references and line‐and‐box diagrams instead of explanatory theory can make only a limited contribution to the literature. I next discuss more generally the pitfalls of conducting research without first developing theory, citing the example of malaria. In the final section of the article, I defend the role of theory‐review articles, such as those published in the Academy of Management Review, and illustrate (again by reference to an example) how such articles are critical to advancing organizational research.

Disasters evolving from hazards are a persistent and deadly occurrence in the United States. Despite this, hazard alerts have remained spatially vague, temporally imprecise, and lack actionable information. These deficiencies indicate a divide between the status quo and what is possible given modern environmental models, geographic information systems (GIS), and smartphone capabilities. This work describes an alternative, prototype system, “FloodHippo,” which integrates operational model outputs, cloud‐based GIS, and expanded communication channels to provide personal and interactive disaster alerts for floods. The precepts and methods underpinning FloodHippo apply equally to other disasters that evolve over space and time, presenting the opportunity for a more intelligent disaster response system. The development of such a system would not only minimize current shortcomings in disaster alerts but also improve resilience through individual action, along with community, academic, and federal cooperation. 相似文献

This study deals with the German Federal Government’s approach of ensuring public support for its ‘Energiewende’, the swift and complete transition to an energy system based on renewable sources. First, the government’s ‘consensus management’ strategy is described as consisting of four elements: the setup of stakeholder deliberation fora; the funding of organisations dedicated to the public promotion of the energy transition; public campaigns that appeal to people’s commitment and the support of research on energy technologies. The study then traces the need for a strong social mandate of the energy transition back to the scope of the regulatory challenge and the recently growing conflicts around implementation, to institutional constraints of a consensus democracy and to the narrative of ‘Energiewende’ as the ‘grand national task’. 相似文献

Based on the elements of social exchange and organizational justice theories, a conceptual model and associated hypotheses were formulated to examine the relationship among community residents and their perceptions of governmental fairness (i.e., distributive, procedural, interpersonal, and informational dimensions), social capital (i.e., cognitive and structural dimensions), and support for government and environmental development. Data were collected from 496 residents in four Korean cities: Busan, Gyeongju, Pohang, and Ulsan. Empirical testing resulted in support for multiple hypotheses. More specifically, cognitive social capital was significantly influenced by distributive, interpersonal, and informational fairness. Structural social capital was significantly affected by distributive and informational fairness. Subsequently, two dimensions of social capital positively influenced two types of support. Overall, the results suggest that the interplay of governmental fairness and social capital is important in influencing residents’ support for government and environmental development. 相似文献

Learning is considered as a promising mechanism to cope with rapid environmental change. The implications of learning for natural resource management (NRM) have not been explored in-depth and the evidence on the topic is scattered across multiple sources. We provide a qualitative review of types of learning outcomes and consider their manifestations in NRM across selected empirical literature. We conducted a systematic search of the peer-reviewed literature (N = 1,223) and a qualitative meta-synthesis of included articles, with an explicit focus on learning outcomes and NRM changes (N = 53). Besides social learning, we found several learning concepts used, including policy and transformative learning, and multiple links between learning and NRM reported. We observe that the development of skills, together with a system approach involving multi-level capacities, is decisive for implications of learning for NRM. Future reviews could systematically compare how primary research applies different learning concepts and discusses links between learning and NRM changes. 相似文献

在深入分析地震新闻报道同质化特征及其原因的基础上,本文认为有效解决地震新闻报道同质化的途径有三:一是相关部门要转变思想,明确地震新闻在地震科普中的重要作用;二是新闻媒体要转变地震新闻报道方式,追求差异化报道;三是要引导受众转变新闻消费观念,以刺激新闻生产者的积极性。 相似文献
