The central focus of this study was to examine types of contact between adolescents and police as determinants of attitudes toward these authority figures. Three value or group expressive determinants — race, deviance, and parental defiance — were used as control variables to specify conditions under which the importance of actual contact with police is enhanced or diminished. Positive contact with police was found to be predictive of positive attitudes and negative contact was predictive of negative attitudes toward police. Further investigation revealed that the relationship between positive contact and positive attitudes toward police became significantly stronger among youths who had experienced negative encounters with police, as well as among those who reported being frequently involved in deviance, and among those who had been defiant of parental authority. The effects of negative contact with police were most significant among whites, those who report infrequent deviant behavior, and those youths who had experienced little or no positive contact with police. 相似文献

Systems approaches possess an ability to deal with large numbers of interacting variables and relations. They are here connected tocitizen information systems (distinguished frommanagement information systems) and to mixed, adaptive, conditional models for urban planning. The latter permit flexible and continuing responses to dynamically changing urban conditions, including citizen attitudes and reactions, as well as to changing economics and technologies. These models are mixed in that they allow actions and reactions from a multiplicity of decisionmakers. The resulting decisions are made only conditionally, rather than once-and-for-all, on a comprehensive basis as in the customary master city plan. Proceeding in this conditional manner, the model then permits adaptation to changing values and objectives as, at each stage, it makes the systems consequences apparent.The systems approach is related to a host of important methodological developments in mathematics, statistics, etc., as well as in electronic computers and their use. These distinguish modern systems approaches from predecessors like the holism of Jan Christiaan Smuts and others in pre-war science. The mixed, conditional, adaptive models suggested here are compared with other approaches like advocacy planning, the comprehensive master city plan and ad hoc planning. It is found to be possible at least in principle, to accommodate all of these and even to extend matters further to include day-to-day as well as longer range facilities plans in the indicated systems approach by virtue of the improved methodologies that may now be used or developed for these purposes.This paper was prepared for presentation before the Division 1 (General), American Psychological Association Meetings in Miami Beach, Florida on September 5, 1970.Also, Joint Urban Sciences Information Institute, Research Report No. 5. 相似文献

Although researchers have identified individual-level predictors of nonphysical bullying among children and youth, school-level predictors (i.e., characteristics of the school environment that influence bullying exposure) remain largely unstudied. Using data from a survey of 1,838 students in 21 Boston public high schools, we used multilevel modeling techniques to estimate the level of variation across schools in student reports of nonphysical bully victimization and identify school-level predictors of bullying. We found significant between school variation in youth reports of nonphysical bullying, with estimates ranging from 25-58%. We tested school-level indicators of academic performance, emotional well-being, and school safety. After controlling for individual-level covariates and demographic controls, the percent of students in the school who met with a mental health counselor was significantly associated with bullying (OR = 1.03, 95% CI = 1.01, 1.06). There was no significant association between school-level academic performance and perceptions of school safety on individual reports of bullying. Findings suggest that prevention and intervention programs may benefit from attending to the emotional well-being of students and support the importance of understanding the role of the school environment in shaping student experiences with bullying. 相似文献

Politics and the life sciences--also referred to as biopolitics--is a field of study that seeks to advance knowledge of politics and promote better policymaking through multidisciplinary analysis that draws on the life sciences. While the intellectual origins of the field may be traced at least into the 1960s, a broadly organized movement appeared only with the founding of the Association for Politics and the Life Sciences (APLS) in 1980 and the establishment of its journal, Politics and the Life Sciences ( PLS ), in 1982. This essay--contributed by a past journal editor and association executive director--concludes a celebration of the association's thirtieth anniversary. It reviews the founding of the field and the association, as well as the contributions of the founders. It also discusses the nature of the empirical work that will advance the field, makes recommendations regarding the identity and future of the association, and assesses the status of the revolution of which the association is a part. It argues that there is progress to celebrate, but that this revolution--the last of three great scientific revolutions--is still in its early stages. The revolution is well-started, but remains unfinished. 相似文献

The article assesses civil society in Putin’s Russia through the lens of the small social movement working against gender violence. Based on questionnaires distributed to movement organizations in 2008-2009, we find significant retrenchment among the NGO segment of the movement, adding evidence to the claim of Russia’s turn toward authoritarianism. However, this innovative, midlevel analysis--not the typical society-wide surveys nor the small number participant observation--also shows that the women’s crisis center movement has made some in-roads in transforming the state, revealing that some democratic opportunities remain at the local level. 相似文献

INTRODUCTION: Drug concentration measured in postmortem adipose tissue may or may not reflect antemortem concentration. To examine the possibility of whether the presence of basic drugs in adipose tissue is the result of postmortem change, we examined: tissues with and without livor mortis, concentration gradients within the adipose layer, and the stability of drug concentrations during the postmortem period. CASE REPORTS: Five drug-related deaths with case histories and analytical data are presented. Adipose tissues with and without livor mortis from the thigh area of the same decedent were analyzed for cocaine. The cocaine concentration of the tissue exhibiting 4+ livor was equivalent to the concentration observed in tissue without livor. Analyses of cross sections of adipose tissues containing cocaine and methamphetamine disclosed that drug concentrations were equally distributed throughout the layer, from just beneath the dermis to directly above the muscle. When morphine and temazepam concentrations were measured in adipose tissues collected from similar sites, but at different times, from the same cadaver, they remained essentially the same over 3 days (approximately 80 h). CONCLUSIONS: Since concentrations were the same in areas with and without livor mortis, the possibility of redistribution into adipose from blood or vascular channels is eliminated. The absence of a concentration gradient within the adipose layer rules out diffusion or permeation from muscle into the adipose layer, and the failure of morphine or temazepam concentration to change over time indicates that drugs in the adipose tissue are stable during the postmortem interval. Our findings support the notion that drugs identified in postmortem adipose tissue are there because of antemortem deposition and not because of any postmortem change or event. 相似文献

A former cocaine and methamphetamine abuser was continuously monitored with both sweat patch and urine testing for approximately 6 months. Thirteen sweat patches were applied and collected, five were positive for cocaine and/or methamphetamine, but all the urine specimens collected were negative at the analytical cut-off levels. The high incidence of false positive sweat patch tests in relation to the sensitivity, specificity, and efficiency of the sweat patch assay is discussed. Possible mechanisms, which can lead to false positive results, are presented. The results of our study raise further questions about the preferential use of the sweat patch in detecting new episodes of drug use in formerly chronic drug users. 相似文献
