In this article, data from the 2005 European Working Conditions Survey are used to examine the relationship between contemporary employment arrangements and the work-related well-being of European employees. By means of a Latent Class Cluster Analysis, several features of the employment conditions and relations characterizing jobs are combined in a typology of five employment arrangements: SER-like, instrumental, precarious unsustainable, precarious intensive and portfolio jobs. These job types show clear relationships with separate indicators of job satisfaction, perceived safety climate and the ability to stay in employment, as well as with an overall indicator for work-related well-being. The findings from this multifaceted approach towards employment quality raise questions about the long-term sustainability of highly flexible and de-standardized employment arrangements.  相似文献

Differential reinforcement of other behavior (DRO) and noncontingent reinforcement were compared as control procedures during the modification of a 3-yr-old preschooler's compliance. The recorded reinforcer was teacher proximity (within 3 ft (0.9 m) of the subject for at least 5 sec) which was often accompanied by positive verbal comments that varied in content across experimental conditions. The verbal content during contingent reinforcement might have been: “Thank you for picking up the blocks”; during noncontingent reinforcement: “You're wearing a pretty dress”; and during DRO: “I don't blame you for not picking up because it isn't any fun”. Contingent reinforcement increased compliance in all manipulation conditions. Noncontingent reinforcement decreased compliance during two reversal conditions. However, the behavior was variable and did not decrease to the low levels reached during the two DRO reversals.  相似文献

We examined how a mother's view of her body, and fatness in general, affects her attitude toward her child's weight and eating. Mothers (N = 118) of 3–5-year-old children filled out a questionnaire designed to assess weight satisfaction, anti-fat attitudes, and how concerned and restrictive they are with regards to their child's weight and eating. We found mothers who were more fearful of being or becoming overweight themselves worried more for their children, although fearful attitudes did not predict restricting a child's eating. These results suggest that maternal attitudes toward their own weight affect their beliefs about their children's weight.  相似文献
