In this paper we explore the context of the relationship between leader-member exchange and organizational citizenship behaviors (OCB). We maintain that workgroup leader's power distance and the extent of task interdependence in the group exert cross-level effects on the LMX-OCB relationship. We assert that leader power distance attenuates the relationship between LMX and OCB, and this effect is stronger in workgroups with high degree of task interdependence. Results of hierarchical linear modeling analysis of data gathered from 245 employees nested in 54 workgroups supported our hypotheses. LMX-OCB relationship was weaker in workgroups led by high power distance leaders. Further, the three-way cross-level interaction between LMX, leader power distance and group task interdependence demonstrated that the tendency for LMX to have a stronger positive effect on OCB when leader power distance was low rather than high was more pronounced in high task interdependence teams. 相似文献

Summary. We develop a general methodology for tilting time series data. Attention is focused on a large class of regression problems, where errors are expressed through autoregressive processes. The class has a range of important applications and in the context of our work may be used to illustrate the application of tilting methods to interval estimation in regression, robust statistical inference and estimation subject to constraints. The method can be viewed as 'empirical likelihood with nuisance parameters'. 相似文献

For two-parameter exponential populations with the same scale parameter (known or unknown) comparisons are made between the location parameters. This is done by constructing confidence intervals, which can then be used for selection procedures. Comparisons are made with a control, and with the (unknown) “best” or “worst” population. Emphasis is laid on finding approximations to the confidence so that calculations are simple and tables are not necessary. (Since we consider unequal sample sizes, tables for exact values would need to be extensive.) 相似文献

We discuss the issue of using benchmark doses for quantifying (excess) risk associated with exposure to environmental hazards. The paradigm of low-dose risk estimation in dose-response modeling is used as the primary application scenario. Emphasis is placed on making simultaneous inferences on benchmark doses when data are in the form of proportions, although the concepts translate easily to other forms of outcome data. 相似文献

现阶段村民自治运作中的权力博弈 总被引:2,自引:0,他引:2
村民自治的运作实际是村落场域内各权力主体之间的博弈过程。在现阶段中国农村村民自治运作中,权力博弈场内的主要局中人是政府、村干部、头面人物、普通村民。由于受村落场域多元性的影响,各类村庄权力主体在不同村庄的公共权力体系中所处的地位和发挥的作用有所差异,因此形成了干部支配型、精英主导型、群众自治型等多种村庄权力结构。村民自治运作中的权力博弈势必导致各类权力主体在村庄公共权力体系中的地位和作用的改变,并引起村庄权力结构的变迁。 相似文献

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework. 相似文献

In this article, we provide a brief introduction to the work of Michel Foucault. Our focus is on the major themes of Foucault's work: discourse, power/knowledge and subjectivity. We demonstrate the rich contribution that Foucauldian theory can make to public relations practice and scholarship by moving beyond a focus on excellence towards an understanding of public relations as a discourse practice with power effects. 相似文献
