Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.  相似文献

Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages.  相似文献

This article examines the impact of nongovernmental organization-sponsored contact and communication on fostering peaceful solutions to ethnic conflict via case studies of the activities of the Project on Ethnic Relations (PER) in Romania, Macedonia, Montenegro, Kosovo, and Serbia. It explores five operational principles that guide PER activity: creating credible, neutral forums for dialogue; maintaining momentum; working within political realities; encouraging indigenous solutions from within existing processes; and acting with the backing of powerful states. These principles explain PER's success as a "weak mediator" of ethnic conflicts. According to this analysis, PER also exhibits organizational characteristics that contribute to success, including nonpartisanship, area expertise and extensive networks of local contacts, and an ability to secure the trust of local actors.
A significant indicator of the success of PER activities is the establishment by conflicting parties of institutionalized mechanisms for addressing their differences. Contrary to the view that electoral competition contributes to conflict, this study finds that the possibility of achieving an electoral advantage by participating cooperatively in conflict resolution activities creates incentives for local actors to recognize opportunities offered by PER activities and leads local actors to heed PER's advice. Finally, the article offers a cautionary observation. While PER's perceived influence with major international actors may contribute to its local successes, once a state actor with the power to impose a solution has committed itself to ending a conflict, its preferences outweigh any local interests in determining the outcome and renders the efforts of a "weak mediator" such as PER irrelevant.  相似文献
