Psychological contract breach and outcomes: Combining meta-analysis and structural equation models.

In this study, meta-analytic procedures were used to examine the relationships between psychological contract perceived breach and certain outcome variables, such as organizational commitment, job satisfaction and organizational citizenship behaviours (OCB). Our review of the literature generated 41 independent samples in which perceived breach was used as a predictor of these personal and organizational outcomes. A medium effect size (ES) for desirable outcomes (job satisfaction, organizational commitment, organizational trust, OCB and performance) was obtained (r=-.

[Identity and commitment in emergency teams].

This paper adopts Tajfel's social identity theory perspective and applies it to the organizational context in order to study emergency intervention teams. Specifically, it is intended to explore the kind of social identification (professional, team, or organizational) prevalent among members of these organizations. It is intended, as well, to establish a clear distinction between two related, and often confused, concepts, i.

[Mobbing: a meta-analysis and integrative model of its antecedents and consequences].

Although mobbing has been extensively studied, empirical research has not led to firm conclusions regarding its antecedents and consequences, both at personal and organizational levels. An extensive literature search yielded 86 empirical studies with 93 samples. The matrix correlation obtained through meta-analytic techniques was used to test a structural equation model.

Identification of a genomic clone to ACC oxidase from papaya (Carica papaya L.) and expression studies.

In this paper are presented structural analysis and expression studies of one genomic clone encoding a 1-aminocyclopropane-1-carboxylate oxidase (ACC oxidase) from papaya. Using RT-PCR amplification of ACC oxidase cDNAs from ripe papaya, a product of 800 bp was obtained, which after sequence analysis was found to code for a protein highly homologous to ACC oxidase proteins. This PCR product was used as a probe for screening a genomic library, and two different groups of clones were obtained as indicated by restriction mapping.
