The present study assessed the comparability of adolescents' (N=184), their mothers' (N=184), and their fathers' (N=184) attitudes toward contemporary societal issues, as well as each familial group's perceptions of the other two groups' attitudes. Results of multivariated analyses of variance indicated that while there were significant overall differences between adolescents' and either parent's self-ratings for the 36 questionnaire items (dealing with such topics as drug use, sexuality, and dress codes), major (i.e., 2-scale-point) differences between generational groups existed on only about 20% of the items. However, as predicted, both adolescents and parents misperceived the extensiveness of the divisions between them. Adolescents significantly overestimated the number of major differences between themselves and their mothers and fathers, while these two parental groups significantly underestimated such divisions. These distortions in perceived attitudes were also reflected in the results of correlational analyses assessing intrafamilial attitude consistencies and inconsistencies across the 36 items. Self-alternative-family-members' perceived attitudes correlations showed greater consistency than existed in the self-alternative-family-members' actual attitudes correlations. Moreover, both analyses of variance and correlational analyses indicated that there was greater similarity between the actual attitudes of the mothers and fathers than between either parental group and their children. These results are discussed in terms of the cognitive and emotional significance of the intrafamilial attitudes of adolescents and parents.Received his Ph.D. from the City University of New York in developmental psychology.

Over the past two decades states have significantly increased their use of competitive bidding to purchase health and social services from private agencies. Competitive contracting is thought to facilitate program administration, to reduce costs, and to increase the quality of delivered services. We evaluate these claims in light of Massachusetts' experience with competitive contracting for mental health care. We find that few of the expected benefits are achieved. In practice, supposedly competitive bidding systems often degenerate into administratively complicated negotiations between the state and private monopolies. This results in higher costs and lower quality of services. In light of this negative assessment, three strategies for reform are proposed and evaluated.  相似文献

Research Summary

For several decades, critics have argued that civil forfeiture laws create incentives for law enforcement to increase departmental revenue by “policing for profit.” By using data on federal equitable sharing payments to nearly 600 local law enforcement agencies between 2000 and 2012, we examine the relationship between the characteristics of state forfeiture laws and equitable sharing payments to local agencies. Our results indicate that agencies in states with state laws that are more restrictive or less rewarding to police collect more in federal equitable sharing. This finding supports the critics’ argument that police behavior in regard to forfeiture activities is influenced by the financial rewards and burdens involved.

Policy Implications

Our results reveal that the findings of investigative journalism and case study research, that is, that police forfeiture activities are influenced by financial rewards, may be more generalizable to law enforcement than previously thought. Despite recent state‐level reforms, federal equitable sharing and most state forfeiture laws provide limited due process protections and have minimal accountability or reporting requirements. Concerns about the impact of civil forfeiture practices on perceptions of procedural justice and police legitimacy are discussed, and possible policy reforms are reviewed.  相似文献

This study presents a series of 16 carriers of hemoglobin S (HbS) who died during various circumstances. Many of the cases were associated with mild to moderate exertion. The onset and/or duration of symptoms varied from a few minutes to several hours with many displaying a prolonged lucid interval with stable vital signs. Despite seeking medical treatment, sickle cell trait-related micro-occlusive crisis was never considered in the differential diagnosis. Several cases were associated with sudden death. In those deaths which were delayed, high anion gap and uncompensated metabolic acidosis were typical and were not heat related. Also characteristic were large increases in creatine kinase, alanine aminotransferase, and aspartate aminotransferase along with myoglobinemia. Although the antemortem diagnosis of rhabdomyolysis was made, the underlying cause was never deduced by the clinicians. The sickling found at autopsy is not always a postmortem artifact, and in the right circumstances can be diagnostic.  相似文献

A case of spontaneous bacterial peritonitis is reported. A methodical postmortem examination failed to disclose cirrhosis or other liver pathology; nor, was any anatomic alteration of the immune system noted. Acquired immunodeficiency syndrome was likewise discounted. A discussion ensues concerning recognition of this entity.  相似文献

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.  相似文献
