Abstract. In an attempt to tighten up its financial systems and improve control of expenditures, the Canadian federal government has set up a new office, that of the Comptroller General. One of this Office's responsibilities is to administer the Treasury Board's policy on program evaluation, which says that all government programs should be periodically reviewed for their effectiveness in meeting goals and for the efficiency with which they are managed. The paper describes the Office's approach to program evaluation, reviews program evaluation policy in three other countries and discusses the principles and practical problems which limit the application of evaluation research. Evaluation activity in Canada is endangered in its cradle by two threats: the tendency of proponents to over-exuberance; and the cynics' view that the activity is of such limited applicability that potential savings are negligible. A third problem is a tendency to fuse together policy-related and management-related assessment activity. Evaluation activity conducted from the operational management point of view which takes program goals for granted will surely result in sequences of small victories and economies. This is worth doing well. But the dramatic import of effectiveness evaluation as a ‘bottom line’ for judging the worth of whole programs — that is, as a policy tool — should not be allowed to generate false expectations about the scope for improvement in routine management of the public service. Sommaire. En vue de fortifier ses systèmes financiers et d'améliorer le contrôle exercé sur ses dépenses, le gouvemement fédéral canadien a créé un nouveau poste, celui du Contrôleur général. Une des responsabilités de cette function est d'administrer la politique du Conseil du trésor en matière d'évaluation de programmes. Cette politique exige que les programmes gouvernementaux soient évalués périodiquement afin de déterminer leur efficacitéà rencontrer leurs objectifs ainsi que la capacité de rendement de leur gestion. Ce document décrit l'approche du Bureau du Contrôleur général en matière d'évaluation de programmes; examine les politiques correspondantes dans trois autres pays; et discute des principes et des problèmes pratiques qui limitent l'applicabilité de l'évaluation en recherche.  相似文献

Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents.  相似文献

A qualitative study was conducted involving clients, victim advocates, and judges participating in one of Miami‐Dade County's (Florida) “therapeutic” juvenile court based programs, the Dependency Court Intervention Program for Family Violence (DCIPFV). The primary objective of this study was to assess how battered mothers’ perceptions of the dependency court judges’ actions impacted the women's motivation to take appropriate actions to promote their own, and their child(ren)'s safety.  相似文献

Police practice of double-blind sequential lineups prompts a question about the efficacy of repeated viewings (laps) of the sequential lineup. Two laboratory experiments confirmed the presence of a sequential lap effect: an increase in witness lineup picks from first to second lap, when the culprit was a stranger. The second lap produced more errors than correct identifications. In Experiment 2, lineup diagnosticity was significantly higher for sequential lineup procedures that employed a single versus double laps. Witnesses who elected to view a second lap made significantly more errors than witnesses who chose to stop after one lap or those who were required to view two laps. Witnesses with prior exposure to the culprit did not exhibit a sequential lap effect.  相似文献

In the United States, all 50 states and the District of Columbia have enacted statutes that allow police officers to make warrantless arrests for domestic violence given probable cause; however, state laws differ from one another in multiple, important ways. Research on domestic violence warrantless arrest laws rarely describe them as anything more than discretionary, preferred, or mandatory, either within their analyses or within the texts of their publications; researchers, and their audiences, may not be aware of the vast and potentially important differences among these laws. In this article, we list the domestic violence warrantless arrest laws for each state, and discuss them in terms of five common elements: the phrasing of the arrest authority; whether additional factors to domestic violence are required to trigger the arrest authority; qualifications to the arrest authority; time limits for warrantless arrest to occur; and whether police officers are required to report why they made a dual or no arrest. We then analyze the common elements of the laws, paying particular attention to how they may encourage or discourage the arrest of alleged domestic violence perpetrators. It is critical that researchers, advocates, and policymakers are aware of these variations in state statutes when conducting or interpreting research or making policy recommendations.  相似文献

Fashion, accessories, and homeware fall outside the regulations of Fairtrade Labelling Organizations International (FLO), which certifies mostly food products. A handful of fashion-led Fair Trade enterprises are now providing ranges of high-quality desirable products, made by workers employed in urban enterprises as well as independent producers in cooperatives. Tabeisa, an NGO involved in Fair Trade retailing, has developed a new regulatory framework which uniquely starts by defining the relations of production between all actors in the chain. This ensures that those not previously covered by existing standards are made visible and receive fair pay and conditions.  相似文献

This paper examines the reliability of Structure from Motion (SfM) photogrammetry as a tool in the capture of forensic footwear marks. This is applicable to photogrammetry freeware DigTrace but is equally relevant to other SfM solutions. SfM simply requires a digital camera, a scale bar, and a selection of oblique photographs of the trace in question taken at the scene. The output is a digital three-dimensional point cloud of the surface and any plastic trace thereon. The first section of this paper examines the reliability of photogrammetry to capture the same data when repeatedly used on one impression, while the second part assesses the impact of varying cameras. Using cloud to cloud comparisons that measure the distance between two-point clouds, we assess the variability between models. The results highlight how little variability is evident and therefore speak to the accuracy and consistency of such techniques in the capture of three-dimensional traces. Using this method, 3D footwear impressions can, in many substrates, be collected with a repeatability of 97% with any variation between models less than ~0.5 mm.  相似文献
