The capacity of police departments to solve crimes and apprehend offenders is low for many types of crime, particularly crimes of profit. This article reviews a variety of studies of police apprehension and hypothesizes that an important determinant of the ability of the police to apprehend criminals is information. The complete absence of information for many types of crime places fairly clear upper bounds on the ability of the police to effect solutions.To discover whether these boundaries are high or low we analyzed data from the 1973 National Crime Panel about the types and amount of information potentially available to police through victim reports and patrol activities. The evidence suggests that if the police rely on information made readily available to them, they will never do much better than they are doing now. On the other hand, there appears to be more information available to bystanders and passing patrols than currently is being used, which suggests that surveillance strategies and improved police methods for eliciting, recording, and analyzing information supplied by victims and witnesses might increase the probability of solving crimes and making arrests. In light of this we review a few possibly helpful innovations suggested in the literature on police productivity and procedure.  相似文献

This article examines the rights of patients, particularly incompetent patients, in long-term care facilities to refuse psychotropic medication. In exploring this topic, the author focuses on the provisions of the Omnibus Budget Reconciliation Act of 1987 which was part of a Congressional solution to afford greater protection to residents of long-term care facilities. Because the legislation has not lived up to expectations, the author advocates for further legislative action to protect the dwindling bundle of rights of the elderly.  相似文献

Hypotheses are tested concerning the relationship between level of and changes in self-attitudes on the one hand and the adoption of membership in the charismatic religious movement on the other hand. The hypotheses are derived from a general theory of deviant behavior. Subjects (generally aged 13–25) were 65 members of a local charismatic religious group and a comparison group of 47 members of three, more traditional urban Protestant churches. Self-attitudes were measured by a self-derogation scale responded to with reference to two points in time: the present and 6 months to 1 year prior to the test administration. The three hypotheses were supported. (1) The charismatic subjects, relative to the comparison subjects, displayed significantly higher levels of self-derogation at the time of adopting membership in the charismatic group. (2) Individuals who adopted membership in the charismatic cults, relative to the comparison group, displayed a significantly greater tendency to decrease the level of self-derogation between the earlier point in time and the point in time when the subjects were interviewed. (3) Significantly greater decrease in self-derogation on the part of the charismatic cult subjects resulted in comparable levels of selfderogation for the charismatic and comparison groups at the time of the interview.Received M.D. from the University of Ottawa in 1960, did his fellowship in psychiatry in Mayo Clinic, 1968–1970, and is a fellow of the American Board of Neurology and Psychiatry (1973). Major interest is religion and psychiatry.Received Ph.D. in sociology from New York University in 1958. Current research interests are social psychiatry and, more specifically, the reciprocal relationship berween self-attitudes and the adoption of deviant response patterns.  相似文献

The paper studies the impact of the EP on legislation on chemical pollutants introduced under the Cooperation procedure. A series of formal and informal analyses have predicted from significant impact of the EP, to limited impact (only in the second round) to no impact at all. Through the analysis of Parliamentary debates as well as Commission and Parliamentary committee documents, we are able to assess the significance of different amendments, as well as the degree to which they were introduced in the final decision of the Council. Our analysis indicates first that less than 30% of EP amendments are insignificant, while 15% are important or very important; second, that the probability of acceptance of an amendment is the same regardless of its significance. Further analysis indicates two sources of bias of aggregate EP statistics: several amendments are complementary (deal with the same issue in different places of the legal document), and a series of amendments that are rejected as inadmissible (because they violate the legal basis of the document or the germainess requirement) are included in subsequent pieces of legislation. We calculate the effect of these biases in our sample, and find that official statistics under estimate Parliamentary influence by more than 6 percentage points (49% instead of 56% in our sample). Finally, we compare a series of observed strategic behaviors of different actors (rapporteurs, committees, floor, Commission) to different expectations generated by the literature.  相似文献
