The adjustment problems associated with sexual abuse, physical abuse, psychological maltreatment, neglect, and witnessing family violence during childhood were examined in three studies. Study 1 demonstrated significant overlap between maltreatment types in parent reports (N = 50) of maltreatment experiences of their child aged 5–12 years. Parental sexual punitiveness, traditionality, family adaptability and family cohesion significantly predicted scores on 4 maltreatment scales and children's externalizing behavior problems. Level of maltreatment predicted internalizing, externalizing, and sexual behavior problems. In Study 2, significant overlap was found between adults' retrospective reports (N = 138) of all 5 types of maltreating behaviors. Parental sexual punitiveness, traditionality, family adaptability, and family cohesion during childhood predicted the level of maltreatment and current psychopathology. Although child maltreatment scores predicted psychopathology, childhood family variables were better predictors of adjustment. Study 3 demonstrated that child maltreatment scores predicted positive aspects of adult adaptive functioning (N = 95).  相似文献

One important aspect of the economic theory of criminal court delay is to understand how the prosecutor and the defendant make their decisions, and how these respond to changes in trial delay. If both parties jointly maximise expected utility, trial delay may increase or decrease the number of trials, depending upon the decision makers' attitudes towards risk. The main policy implication is that providing the criminal courts with more resources in the form of additional judges and court capacity may lengthen the trial queue rather than shorten it. This is a counterintuitive result contrary to popular belief.  相似文献

The concern driving current debate on agricultural extension is increasingly that of how to help farmers learn how to deal with the complex world around them responsibly and profitably, in such a way that the extension worker is ancillary. This article seeks to deconstruct and provide a more reasoned assessment of agricultural extension services through a reflection on development paradigms, adult education, individual empowerment, and institutional pluralism. By calling into question the underlying ethical dimensions of agricultural extension, it is possible to develop an alternative paradigm and thereby generate new insights into it. The article concludes that the raison d'être of agricultural extension today must be to create an ethical basis which ensures that extension practices are more inclusive and thus responsive to the needs of farmers and other rural populations, integrating individual expectations into the wider socio-economic, cultural, political, and geographical environment.  相似文献
