Indicator systems to report on concepts such as sustainability and progress have become a key policy response by governments to concerns over environmental degradation and social and economic instability. When developed by a national bureau, public service imperatives suggest that concepts such as ‘sustainability’ and ‘progress’ should be addressed without offending the ideology of political actors. We offer a case study of the Australian Bureau of Statistics (ABS) Measures of Australia's Progress (MAP) indicator system. The ABS has chosen to avoid offering a clear definition of what progress means, or a conceptual framework linked to a definition to explain the selection of indicators. ‘Progress’, however, is a socially defined, normative concept. Such concepts cannot be understood without reference to cultural and political processes. By seeking to avoid a perception of cultural or political bias the ABS has limited MAP's capacity to measure progress. We conclude with suggestions on how MAP might be improved.  相似文献

Cold case squads have garnered much attention; however, they have yet to undergo significant empirical scrutiny. In the present study, the authors interviewed investigators and reviewed 189 solved and unsolved cold cases in Washington, D.C., to determine whether there are factors that can predict cold case solvability. In the interviews, new information from witnesses or information from new witnesses was cited as the most prevalent reason for case clearance. The case reviews determined that there were factors in each of the following domains that predicted whether cases would be solved during cold case investigations: Crime Context, Initial Investigation Results, Basis for Opening Cold Case, and Cold Case Investigator Actions. The results suggest that it is possible to prioritize cold case work based on the likelihood of investigations leading to clearances.  相似文献

Objectives

Projection effects have been shown to bias respondent perceptions of peer delinquency, but network data required to measure peer delinquency directly are unavailable in most existing datasets. Some researchers have therefore attempted to adjust perceived peer behavior measures for bias via latent variable modeling techniques. The present study tested whether such adjustments render perceived peer coefficients equal to direct peer coefficients, using original data collected from 538 young adults (269 dyads).

Methods

After first replicating projection effects in our own data and examining the degree to which measures of personal, perceived peer, and direct peer violence represent empirically distinct constructs, we compared coefficients derived from two alternative models of personal violence. The first model included an error-adjusted latent measure of perceived peer violence as a predictor, whereas the second substituted a latent measure of directly-assessed, peer-reported violence.

Results

Results suggest that personal, perceived peer, and direct peer measures each reflect fundamentally separate constructs, but call into question whether latent variable techniques used by prior researchers to correct for respondent bias are capable of rendering perceived peer coefficients equal to direct peer coefficients.

Conclusions

Research cannot bypass the collection of direct peer delinquency measures via latent variable modeling adjustments to perceived peer measures, nor should models of deviance view perceived peer and direct peer measures as alternative measures of the same underlying construct. Rather, theories of peer influence should elaborate and test models that simultaneously include both peer measures and, further, should attempt to identify those factors that account for currently unexplained variance in perceptions of peer behavior.  相似文献

This study examined relations among stressors, perceived social competence, attributional style, and depressive symptoms in young urban schoolchildren. Data were collected from 85 5- to 11-year-olds, mostly African American, who attended a public elementary school in a low-income urban area. Social competence was examined as a potential mediator, and attributional style was examined as a potential moderator of the relation between stressful life events and depressive symptoms. Separate analyses were conducted by age and gender. For older children and girls, main effects were found for stressful life events as predictors of depressive symptoms. Mediational analyses indicated that perceived peer acceptance served as a mediator of the relation between stressful life events and depressive symptoms for girls. In addition, attributional style moderated the relation between stressors and depressive symptoms in the older children. Together, findings suggest that significant relations exist among stressful life events, social and cognitive processes, and depressive symptoms in young urban children and that these relations are influenced by gender and development.  相似文献

Secure provision for women in both the Criminal Justice System and the Health Service has evolved in the last decade, in line with emerging gender-specific policy. Notable gains have been the approach to self-harm in prison and a reduction in the inappropriately high levels of secure hospital care. Although treatment pilots in UK settings are in progress, much practice remains poorly described and insufficiently evaluated. Recent strategic initiatives by both the Ministry of Justice and the Department of Health, as well as the commissioning changes that have followed the Health and Social Care Act 2012, provide a basis for reconsideration and a further paradigm shift. Suggestions for a reinvigorated model of gender-sensitive provision are made, relying on principles of resilience and autonomy.  相似文献

Animal-scavenging alterations on human remains can be mistaken as human criminal activity. A 32-day study, documenting animal scavenging on a human cadaver, was conducted at the Southeast Texas Applied Forensic Science facility, Sam Houston State University, Huntsville, Texas. A Stealth Cam Rogue IR was positioned near the cadaver to capture scavenging activity. An atypical scavenger, the bobcat, Lynx rufus, was recorded feeding on the cadaver. Scavenging by bobcats on human remains is not a predominant behavior and has minimal documentation. Scavenging behaviors and destruction of body tissues were analyzed. Results show that the bobcat did not feed on areas of the body that it does for other large animal carcasses. Results also show the bobcat feeds similarly during peak and nonpeak hours. Understanding the destruction of human tissue and covering of the body with leaf debris may aid forensic anthropologists and pathologists in differentiating between nefarious human activity and animal scavenging.  相似文献

The purpose of this study was to conduct a longitudinal examination of predictors of sexual aggression among male juvenile offenders. Four hundred and four adolescent males between the ages of 14 and 17 years were recruited from juvenile probation offices to take part in a prospective study of substance use and sexual risk. At baseline, participants completed a series of questionnaires that assessed putative risk factors for sexual aggression. They then completed a measure of sexual aggression at the 6-month follow-up period. Correlational analyses revealed that participants who reported hard drug use, more frequent alcohol and marijuana use, and less severe offenses reported engaging in more severe sexual aggression. In addition, participants who reported higher impulsivity, sensation seeking, and externalizing behaviors also reported participating in more severe sexual aggression. When these variables were included in a regression analysis, only externalizing behaviors and severity of offense uniquely predicted severity of sexual aggression at the 6-month follow-up.  相似文献

A Tale of Two Taxes: The Fate of Environmental Tax Reform in Canada   总被引:1,自引:0,他引:1  
Policy makers who embrace market‐based approaches to environmental regulation, typically eschew carbon taxes in favor of the political advantages of cap and trade, which offers lower visibility of costs to consumers and the opportunity to allocate valuable permits freely to industry. Against this backdrop, the article examines two surprising proposals for carbon taxes, by the government of British Columbia (BC) and by the federal Liberal Party of Canada. Both reflected a triumph of party leaders' normative “good policy” motives over “good politics.” The BC tax alone succeeded first because it was adopted by a party already in government. Second, the onset of a recession before the next elections shifted voters' attention to the economy, which advantaged the BC Liberals but disadvantaged their federal counterparts. However, proposals for carbon taxes were unpopular in both jurisdictions, offering a cautionary tale concerning the fate of politicians' normative commitments absent electoral backing.  相似文献
