The mediating role of affective commitment in the relation of the feedback environment to work outcomes

The Feedback Environment, as opposed to the formal performance appraisal process, is comprised of the daily interactions between members of an organization (Steelman, Levy, & Snell, in press). Relations between the feedback environment and work outcome variables such as Organizational Citizenship Behavior (OCB) were examined through the mediating effects of affective commitment. Results indicate that affective commitment mediates the relation between the feedback environment and organizational citizenship behavior, and this mediated relation is stronger for OCBs directed at individuals than directed at the organization as a whole. Conclusions and implications are discussed.     

应用Markov模型进行临床决策分析的思考

Human reactions to technological failure: How accidents rooted in technology vs. human error influence judgments of organizational accountability

Two experiments examine how the identification of technology as a causal factor in an organizational accident influences judgments of organizational accountability. In study 1, organizations were found to be held less accountable for their actions when a misfortune was rooted in a computer error than when rooted in human error. The predicted mechanism for this effect, counterfactual thinking, was confirmed. Specifically, technologically induced accidents were found to generate fewer counterfactual thoughts of better possible outcomes than similar accidents resulting from human error. Study 2 replicated the findings of study 1 in a more natural setting and using a less intrusive measure for counterfactual thoughts.     

So what do you think of the organization? A contextual priming explanation for recruitment Web site characteristics as antecedents of job seekers’ organizational image perceptions

Although job seekers’ organizational image perceptions can influence attraction to recruiting organizations, little is known about how these perceptions are formed or modified. To address this research gap, the authors drew from research in social cognition theory and demonstrated that recruitment Web site characteristics influenced the development and modification of organizational image perceptions via a priming mechanism. Results of two studies showed that having technologically advanced Web site features and depicting racially diverse organizational members served as contextual primers and influenced participants’ organizational image perceptions. Results also revealed that participants’ familiarity with recruiting organizations moderated the effects of these Web site characteristics on several dimensions of organizational image such that effects were weaker for more familiar organizations. These findings suggest that organizations can manage job seekers’ organizational image perceptions through strategic recruitment Web site design; however, such attempts may be tempered by job seekers’ familiarity with the organization.     

Linking the fits, fitting the links: Connecting different types of PO fit to attitudinal outcomes

In this paper we explore the linkages among various types of person-organization (PO) fit and their effects on employee attitudinal outcomes. We propose and test a conceptual model which links various types of fits—objective fit, perceived fit and subjective fit—in a hierarchical order of cognitive information processing and relate them to employee organizational commitment and job satisfaction. By unveiling how the different types of fit relate to each other in influencing individual outcomes, we address some of the theoretical and methodological concerns in the use of different methods in measuring PO fit.     

The relationship between psychological contract breach and organizational commitment: Exchange imbalance as a moderator of the mediating role of violation

This study tested the mediating role of violation in the relationship between breach and both affective and continuance commitment and the extent to which this mediating role is moderated by exchange imbalance amongst a sample of 103 sales personnel. Results suggest that violation mediated the relationship between breach and commitment. Also, results suggest that perceived exchange imbalance moderates this mediating pathway: Low exchange imbalance increases the mediating role of violation in the case of affective commitment. On the other hand, exchange imbalance failed to moderate the mediating influence of violation in the case of continuance commitment. Results are discussed in view of the importance of a) including both measures of violation and breach in future studies and b) the role of social exchange in explaining psychological contract violation.
