The relation between overcommitment and burnout: does it depend on employee job satisfaction?

Using the Conservation of Resources (COR) theory as a framework, we hypothesized a maladaptive role played by overcommitment in the escalation of burnout. We further specified our model by testing an interaction effect of job satisfaction. By using a longitudinal design, we proposed a moderated mediational model in which burnout at Time 1 (T1) increases overcommitment, which in turn leads to more burnout one month later. We further expected to find a moderating role of job satisfaction in the link between overcommitment and burnout at Time 2 (T2). A group of 86 white-collar workers in personnel services in Italy (longitudinal response rate = 77.48%) participated in our study. The findings supported our hypotheses even when controlling for gender and role stressors. In particular, by using bootstrapping procedures to test mediation, we found evidence that employees reporting burnout tend to develop a maladaptive coping style, i.e., overcommitment, which in turn increases burnout over time. This relation was particularly strong for dissatisfied employees. These results highlight the importance of overcommitment for burnout escalation, as well as of job satisfaction, since it may mitigate, at least in the short term, the effect of such dysfunctional strategies.     

Workplace bullying and its relation with work characteristics, personality, and post-traumatic stress symptoms: an integrated model

Workplace bullying refers to prolonged exposure to frequent hostile behaviors at work, which can lead to severe stress reactions. Research in this area has not revealed a clear picture on how bullying escalates in organizations. Drawing on recent developments in work stress theory, this study tested a comprehensive model of bullying in which work environmental and personality factors were hypothesized to act as antecedents of bullying and post-traumatic stress symptoms as an outcome. Structural equation modeling on data provided by 609 public sector employees in Italy showed that job demands (workload and role conflict) and job resources (decision authority, co-worker support and salary/promotion prospects) were related to bullying over and above neuroticism, and that bullying mediated the relationship between job demands and PTSD symptoms. Evidence also emerged for a buffering effect of job resources on the job demands-bullying relationship. Overall results are compatible with a view of bullying as a strain phenomenon, initiated by both work environmental and personality factors.     

On Some Compatible Operations on Heyting Algebras

We study some operations that may be defined using the minimum operator in the context of a Heyting algebra. Our motivation comes from the fact that 1) already known compatible operations, such as the successor by Kuznetsov, the minimum dense by Smetanich and the operation G by Gabbay may be defined in this way, though almost never explicitly noted in the literature; 2) defining operations in this way is equivalent, from a logical point of view, to two clauses, one corresponding to an introduction rule and the other to an elimination rule, thus providing a manageable way to deal with these operations. Our main result is negative: all operations that arise turn out to be Heyting terms or the mentioned already known operations or operations interdefinable with them. However, it should be noted that some of the operations that arise may exist even if the known operations do not. We also study the extension of Priestley duality to Heyting algebras enriched with the new operations.     

A new American dilemma? The effect of ethnic identification and public service on the national inclusion of ethnic minorities

Three experiments integrate research from political science and social psychology to examine the consequences of two competing visions of American national identity. American identity has been defined not only in terms of shared ethnocultural heritage originating in Europe (the ethnocultural prototype) but also in terms of shared commitment to civic service (the civic responsibility prototype). Three experiments tested the consequence of highlighting each of these national prototypes on perceivers' inclusion of ethnic minorities as legitimately American. Experiments 1–3 showed that highlighting ethnic minorities' allegiance to their ethnic subgroup (versus downplaying it) challenges the ethnocultural prototype and makes ethnic minorities appear less American. Process data showed that this effect was mediated by increased threats to American distinctiveness. By contrast, emphasizing ethnic minorities' national service (versus local community service) highlights ethnic minorities' fit with the civic responsibility prototype and makes ethnic minorities appear more American (Experiments 2–3). Process data showed that this effect was mediated by enhanced American distinctiveness. Collectively, these experiments highlight how inclusion of ethnic minorities in the nation can wax and wane depending on which definition of national character is salient in the social context.
