abstract This article considers the justice of requiring employment as a condition of receiving public assistance. While none of the main theories of justice prohibits work requirements, the arguments in their favour are weak. Arguments based on reciprocity fail to explain why only means‐tested public benefits should be subject to work requirements, and why unpaid dependant care work should not count as satisfying citizens’ obligations to reciprocate. Arguments based on promoting the work ethic misattribute recipients’ nonwork to deviant values, when their core problem is finding steady employment consistent with supporting a family and meeting dependant care responsibilities. Rigid work requirements impose unreasonable costs on some of the poor. A welfare system based on a rebuttable presumption that recipients will work for pay, conjoined with more generous work supports, would promote justice better than either unconditional welfare or strict requirements [ 1 ].  相似文献

Abstract

Kinston, Loader and Miller (1987) have developed the Family Health Scale (FHS), a research instrument designed to assess a family's level of overall functioning based upon the clinical observation of family interaction. The authors state that the FHS is primarily a research tool, allowing its users to test hypotheses about family dysfunction, to examine changes in the family longitudinally, and to categorize families by “degree of disturbance.” While not its principal use, the scale is also thought to have teaching utility.  相似文献

A dyadic interactive aggression paradigm tested hypotheses from the General Aggression Model about how trait aggressiveness can create behaviorally hostile social environments. Pairs of college student participants competed in a modified reaction time task in which they repeatedly delivered and received each other's punishments. The trait aggressiveness of both participants influenced the punishment intensities (aggression level) set by each member of the dyad on later trials. Furthermore, there was a pattern of escalation from early to later trials. These trait aggressiveness effects (both self and partner) on later aggressive behavior were largely mediated by partner aggression levels during early trials. Results also suggested two aggressive motives--hostile and instrumental--resulted from high partner aggression during early trials and these motives partially mediated the effects of trait aggressiveness and of early trial aggression on later aggressive behavior.  相似文献

In most problem-solving activities, feedback is received at the end of an action sequence. This creates a credit-assignment problem where the learner must associate the feedback with earlier actions, and the interdependencies of actions require the learner to remember past choices of actions. In two studies, we investigated the nature of explicit and implicit learning processes in the credit-assignment problem using a probabilistic sequential choice task with and without a secondary memory task. We found that when explicit learning was dominant, learning was faster to select the better option in their first choices than in the last choices. When implicit reinforcement learning was dominant, learning was faster to select the better option in their last choices than in their first choices. Consistent with the probability-learning and sequence-learning literature, the results show that credit assignment involves two processes: an explicit memory encoding process that requires memory rehearsal and an implicit reinforcement-learning process that propagates credits backwards to previous choices.  相似文献

Being in the numeric minority (e.g., being a solo woman in a group of men) influences how well a person performs within a work group. But being the solo member is only one way in which people can be atypical in a group; a person can also represent a social or demographic category that has not typically been associated with the task that the group is working on. Using a design with four categories of group composition (minority, balanced, majority, homogeneous) and two categories of tasks (sex-typical, sex-atypical) we found that the sex composition of the group interacted with the sex typicality of the task to influence both positive deferrals by group members and individual performance in groups. But, rather than consistently reducing performance as prior research has suggested, being numerically atypical enhanced individual performance when the task was typical for that person’s sex. Further, positive deferrals mediated between the interaction of numeric composition and task typicality in influencing individual performance suggesting that both majority group members and the solo member affect one another’s performance in groups. We conclude by discussing why understanding the interplay between these two sources of stereotyping, numeric composition and task typicality, is important for understanding the social nature of individual performance in groups.  相似文献

The study delineated depressive symptoms and modeled emotional distress in persons living with HIV disease in nonmetropolitan areas of 13 U.S. states. Participants (N=329) were enrolled in a randomized clinical trial of a telephone-delivered, coping improvement group intervention, and 60% reported moderate or severe levels of depressive symptomatology on the Beck Depression Inventory. Structural equation modeling indicated that participants who experienced more severe HIV symptomatology, received less social support, and engaged in more avoidant coping also experienced more emotional distress (a latent construct comprising depressive symptoms and emotional well-being). Greater HIV-related stigma and rejection by family led to more emotional distress, with social support and avoidant coping mediating almost entirely the effects of the former 2 variables. The model accounted for 72% of the variance in emotional distress in nonmetropolitan persons living with HIV disease.  相似文献
