Social loafing was investigated by testing a multilevel model among 23 intact work groups comprised of 168 employees representing two organizations. Results demonstrated that as hypothesized at the individual level, increases in task interdependence and decreases in task visibility and distributive justice were associated with greater occurrence of social loafing. At the group level, increased group size and decreased cohesiveness were related to increased levels of social loafing. Of particular interest was the finding that group member perceptions of perceived coworker loafing was associated with reduced social loafing, opposite of our predictions. We suggested that this unexpected finding may provide evidence of a social compensation effect. 相似文献

We use an event-study analysis to understand how alliance activity affects firm risk. The risk measure is the implied volatility of a firm’s stock price and the events are alliance announcements to the market. We build on the previous event-studies in the alliance literature that focus on the change in shareholder value by taking the first step in delineating what part of that value arises from the changes in the firm’s risk. The analysis reveals that a number of factors within a firm’s control can be used to manipulate risk exposure in an alliance, including the similarity of the firm’s and the alliance’s core activities, the governance form of the alliance, and the function of the alliance. 相似文献

Because current management theories evolved in the context of brick-and-mortar firms, this paper examines three key questions raised by the advent of e-business: (1) Will the strategy types found among e-business firms resemble Porter’s (1980) generic strategies? (2) Will we find performance differences among e-business firms pursuing different types of strategies? (3) Will we find differences in the strategy-performance relationships of pure online firms (pure plays) and firms with both online and offline operations (clicks-and-bricks)? We conclude that integrated strategies that combine elements of cost leadership and differentiation will outperform cost leadership or differentiation strategies. We also argue that, regardless of business strategy type, clicks-and-bricks firms that closely integrate their on- and offline operations will enjoy performance advantages over their pure play counterparts. 相似文献

百年中国经历了农业社会、工业社会和信息社会的变迁。经济社会形态的演化不是简单的单线,远比我们想象的直线历史上升的过程要复杂得多。信息社会出现后,农业社会和工业社会仍在延续。中华民族多元一体格局所体现的文化关系,是在悠久的中国文明史进程中发展起来的,与近代以来中国的民族国家建设走过的特殊道路,有着难以分割的密切关系,也与世界的历史进程分不开。全球化过程中的“文化自觉”,指的就是世界范围文化关系的多元一体格局的建立,即全球范围内实行和确定“和而不同”的文化关系。 相似文献

Internet technology has become an informational resource for most health care consumers. Online information, discussion, and support groups, in the form of message boards, listservs, and chat rooms are emerging as parts of virtual self-health-care network. This paper examines the extent to which participation in online health discussion groups was reported to be helpful in increasing medical knowledge and in enhancing the participatory patient role of health care consumers in interaction with health care service professionals. Data for this study was collected from 350 patients who participated in Internet discussion groups for cancer patients. The findings of the study indicated the important impact of Internet health discussion groups on health care management practices as perceived by health care consumers, including empowerment through knowledge and proactive participation in cancer care management. This research contributes to understanding the patient perspective and assesses the perceived importance of Internet groups by health care consumers. 相似文献

The objective of the study was to evaluate the occurrence of Burnout Syndrome in 100 teachers of six public high schools and its correlation with working conditions in a southeast city of Brazil. Characterization of the sample occurred after application of a socio-demographic questionnaire. Evaluation of the working conditions was done by means of an Ergonomic Working Analysis. The presence of Burnout Syndrome was evaluated by means of the Maslach Burnout Inventory. The sample presented the predominance of women, with an average age of 40.4 and the majority married with children. Roughly 50% had less than 10 years of service, and more than half of the teachers taught more than 18 classes per week. Hoarseness after work was principally reported among women, which required many days off for health treatment. Environmental conditions reflect inadequacy in relation to noise, light, humidity and temperature. Presence of pain in the upper limbs was especially high among women. Risk of musculoskeletal disorders in the upper limbs predominated as moderately important to significant. We also identified an average distance walked by teachers of 1.5 Km and an average of 4.2 Kg of school supplies carried between classes. The Burnout Syndrome presented a high score for depersonalization principally among men, but it has association with both sexes. Emotional exhaustion correlates with noise, depersonalization, and personal fulfillment, in addition to the high number of weekly lessons. It can be concluded that Burnout syndrome is present among teachers, principally in terms of depersonalization, deserving the attention of government officials and the schools, as well as the teachers themselves. 相似文献
