The discriminant validity of perceptions of organizational politics, organizational support, and procedural and distributive justice was examined as the distinctions between these variables have been blurred in past research. Results from a sample of 418 full‐time employees provided evidence of discriminant validity for these variables. First, structural equation modelling was used to isolate the best structural representation of these four variables. Then, six theoretically relevant predictors (i.e., leader–member exchange, centralization, formalization, co‐worker cooperation, role conflict, and locus of control) were examined in an effort to provide further conceptual separation. Five of the six antecedents distinguished among politics, justice, and support. Suggestions for additional research that can shed light on the distinctions and similarities of these variables are offered based on the results of this study.

Matched data collected from 143 employees and their immediate supervisors of a private sector organization indicated that employee perceptions of procedural justice were only related to supervisor-rated affective commitment among employees with a strong exchange ideology. That is, individuals motivated by a fair exchange exhibited fewer affective commitment behaviors when they viewed the environment as unfair than when they perceived it to be fair. Individuals comparatively indifferent to a fair exchange did not alter their affective commitment behaviors regardless of the level of perceived environmental fairness. These results illustrate the importance of considering individual differences in exchange ideology when attempting to alter the work environment for the purpose of increasing commitment. Implications for research and management practice are presented. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

We documented the spawning patterns of the leopard grouper, Mycteroperca rosacea, from April to June 2005 in the central Gulf of California, Mexico to draw comparisons with other aggregate-spawning groupers
and provide information useful for management of their fishery. Adults formed spawning aggregations of 150 to >700 individuals
at specific sites, and spawning occurred daily at these sites from late April through early June. Courtship occurred throughout
the day, but spawning was restricted to the evening hours. Adults spawned in groups of 6–40 fish, and pair-spawning was not
observed. The group-spawning behavior of adults and the gonosomatic indices of mature males (maximum = 7.2%) suggest that
sperm competition was present. The site-specificity of leopard grouper spawning aggregations and diel spawning period were
typical of most aggregating groupers, and the size and structure of these aggregations was similar to other species in the
genus Mycteroperca. Leopard grouper behavior patterns were unusual in that spawning aggregations persisted for extended periods, spawning was
not synchronized with the lunar cycle, and adults aggregated during non-spawning periods. The extensive duration and site-specificity
of spawning aggregations and the propensity of M. rosacea to form aggregations year-round increases the vulnerability of the species to overfishing. Policies that limit harvest from
these aggregations are needed to improve the management of leopard grouper fisheries in the Gulf of California. 相似文献
