Police student officers' attitudes towards domestic disputes following family-crisis-intervention training are analyzed. A total of 359 student officers from fourteen training classes participated in the study. The most dramatic improvement in attitudes was observed in officers' perceptions of disputants and in their perceptions of domestic disturbance calls. The study also investigated the attitudes of student officers toward organizational policy, training, and community relations. Student officers' attitudes significantly improved in thirty-one of fifty-one items (p < .05). In general, the changes in attitudes demonstrated that the family-crisis-intervention program did affect the attitudes of student officers in the predicted direction of change. Following training, student officers were more likely to view domestic disputes as legitimate police business and more likely to believe that their actions could influence families in crisis and that people in crisis both want, and will benefit from, assistance. It is concluded that crisis-intervention training appears to be responsible for the change in officer attitudes and that family-crisis training should be included in the curriculums of police training academies.  相似文献

Numerous studies have established a strong connection between the use of illicit drugs and the commission of other illegal activities, including both predatory and property crimes. No study, however, has examined the cost of crimes associated with drug users both as victims and as perpetrators. In the present study, recent data were analyzed from a targeted sample of chronic drug users (CDUs) and a matched sample of non-drug users (NDUs) in Miami-Dade County, Florida, to estimate the incremental cost of crime associated with CDU. Two separate models were employed to estimate (1) the probability of being a victim or a perpetrator of crime and (2) the cost of crime for both situations. The cost measures were transformed to reduce the influence of extreme outliers, and a smearing technique was used to compare the cost of crime for CDUs relative to NDUs. The findings illustrate that criminal activity among CDUs is circular, extensive, and costly. Implications for law enforcement, criminal justice policy, and substance abuse treatment are discussed.  相似文献

We believe a lack of transparency undermines both the credibility of, and interest in, stated choice studies among policy makers. Unlike articles reporting the results of contingent valuation studies, papers in the stated choice literature rarely present simple tabulations of raw response data (that is, a table or graph showing the percentage of respondents agreeing to purchase a good or service, or vote for a proposed management plan as a function of price). We describe an approach for adding “policy” tasks to a standard orthogonal‐in‐attribute‐levels research design that allows the researcher to plot raw responses as a function of changes in only one characteristic of the offered good or service. We demonstrate this approach using data from a stated choice study of private demand for cholera and typhoid vaccines in Kolkata, India, carried out in the summer of 2004. © 2006 by the Association for Public Policy Analysis and Management.  相似文献

During adolescence dramatic physical changes take place which the individual must incorporate into his or her evolving body image. The impact of different school environments on this incorporation process is explored using data on 225 White females from a longitudinal study. Differences in physical characteristics between early, middle, and late developers were assessed each year. The effects of pubertal timing on satisfaction with body image dimensions and self-esteem were then explored for sixth- and seventh-graders within different school environments. Reference group theory was used to examine three alternative hypotheses. Early versus late onset of menarche had different effects on certain aspects of satisfaction with body image, depending on the school environment. Results support the strength of the cultural ideal of thinness for women, but no other hypothesis had consistent support. The findings indicated the need to consider a multiplicity of factors in relation to specific body image dimensions.This study has been funded by NIMH grant R01 MH-30739 and a grant from the William T. Grant Foundation. In addition, the work of the second author has been supported by a Research Development Award from the National Institute of Mental Health, #2 K02 MH-41688.Received his Ph.D. from the University of Minnesota.

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed “behind armor blunt trauma” (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400–460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear.  相似文献
