The problem of adolescent drug use received a great deal of attention both in criminological theory and public policy. Predominant among theories was Akers' social learning theory which examined the role of learning through a process of imitation, modeling, and reinforcement. Public policy led to the development of programs such as Drug Abuse Resistance Education (DARE) that aimed to warn youths of the dangers of drug use. In line with research findings, both theory and policy gave a central role to peers in understanding adolescent drug use. Less attention was given to another important finding in the literature, that those who used drugs often perceived the drugs as solutions to problems. Using social learning theory, the role of perceptions of drug use as an effective problem solver was examined. Results indicated that a more explicit recognition of the use of drugs to deal with problems might inform both theory and policy.  相似文献

This article advances our understanding of the effects of monetary rewards on public employee performance and of the contingencies that may moderate these effects. In a randomized control‐group experiment with nurses working at a local health authority in Italy, performance‐related pay (PRP) had a larger effect on task performance when the rewards were kept secret than when they were disclosed. The negative interaction between PRP and visibility was stronger among participants who were exposed to direct contact with a beneficiary of their efforts, which heightened their perception of making a positive difference in other people's lives. These results are consistent with theoretical predictions that monetary incentives for activities with a prosocial impact may crowd out employee image motivation. There were no crowding‐out effects when a symbolic reward was substituted for the monetary incentive.  相似文献

Being absent from work due to sickness is a critical issue for individuals and their employers, but it has traditionally fallen outside the scope of EU employment legislation. This article argues that this is changing; it examines case‐law under the Working Time and Employment Equality Directives. The article considers the justifications that the Court of Justice has advanced to explain this expansion in EU employment law. It finds that the Court has, at times, invoked fundamental social rights as a basis for interpreting employment legislation in a manner favourable to workers. Yet the way in which the Court deploys rights‐based reasoning can be difficult to anticipate, not least the countervailing weight attached to the interests of employers. The case studies indicate that fundamental rights discourse offers a possible foundation for more extensive readings of employment legislation, but it is not a simple ‘trump card’ for advocates of stronger worker protection.  相似文献

Asphyxiating laryngeal cyst   总被引:1,自引:0,他引:1  
Cysts of the larynx are uncommon lesions that on rare occasions may cause sudden death. We report herein the asphyxial death by an obstructing vocal cord cyst in a woman whose body was found in a setting that aroused suspicions of foul play. Features of this case and the autopsy findings are compared with a literature review of laryngeal cysts.  相似文献
