Hierarchical Position, Gender, Accident Severity, and Causal Attribution

The two studies reported here confirmed the role of the attributor's hierarchical level in causal attributions about accidents in different types of organizations. In both studies, supervisors vs. subordinates had to analyze a minor work accident vs. a serious one. The first study used male vs. female subjects, whereas the second compared the target's position in the same (in-group) vs. different (out-group) hierarchical level as the attributor. In all cases, more internal attributions than external ones were given to explain the accident. These results demonstrate a tendency toward defensive attribution, whereby people tend to protect themselves or their group from blame or prejudice (Shaver, 1970a). This self-protective attribution bias was found to increase with accident severity, particularly in Study 2. The conclusion offers some suggestions for accident analysis and prevention.     

Bicuculline infusion into the accessory olfactory bulb facilitates the induction of maternal behavior in rats

The GABAA antagonist bicuculline, intracranially infused into the accessory olfactory bulb (AOB), facilitated the expression of maternal behavior (MB) in virgin Wistar female rats. Behavioral effects were observed 24 hours after infusion and were injection dependent. Pheromonal stimuli, generated by the pups, are thought to exert an inhibitory effect on vomeronasal nuclei involved in MB in virgin rats. The present study investigated the possibility that a decrement in AOB output, resulting from long-term compensatory synaptic changes to chronic bicuculline infusion, would facilitate the expression of MB. The implications of our findings for the mechanisms involved in the induction of MB and the maternal experience effect are discussed.     

Antecedents and consequences of workplace bullying: a longitudinal analysis with a structural equation model

Most studies focusing on the antecedents and consequences of workplace bullying have used a cross-sectional design, which impedes determining the causality of the relationships. In the present work, we analyzed, by means of structural equation models, the relationship between workplace bullying and some variables that are considered antecedents (interpersonal conflicts, role ambiguity, role conflict, and workplace social support) or consequences (health complaints and inclination to absenteeism from work) of this phenomenon. Multicenter study with two phases. The sample consisted of 696 employees from 66 centers. Workplace bullying was assessed by means of the "Mobbing-UNIPSICO" questionnaire, and the other variables with frequency scales. The cross-sectional models indicated a significant association between role conflict, workplace social support, and workplace bullying in both study periods. Concerning the longitudinal relationships, only workplace social support was a significant predictor of workplace bullying, which, in turn, was a cross-sectional and longitudinal predictor of workers' health complaints. Our results show the mediating effect of workplace bullying between certain work conditions and health complaints, and it is recommendable to replicate these findings in a multi-occupational sample.     

肝病性糖尿病的发病机制及治疗进展

肝源性糖尿病为继发性糖尿病,因肝实质损害而导致,患者以餐后高血糖和葡萄糖耐量减低为特征.发病机制与肝病时肝糖原合成能力降低,胰岛素抵抗有关.治疗原则是改善和保护肝功能,降低高血糖,缓解症状.所以该病在诊治方面与2型糖尿病有很大区别,本文在此综述如下.
