Research has demonstrated that pilots contain multiple shifting purposes, not all of which relate to simple policy testing or refinement. Judging the success of policy pilots is therefore complex, requiring more than a simple judgment against declared goals. Marsh and McConnell provide a framework against which policy success can be judged, distinguishing program success from process and political success. We adapt Boven's modification of this framework and apply it to policy pilots, arguing that pilot process, outcomes and longer-term effects can all be judged in both program and political terms. We test this new framework in a pilot program in the English National Health Service, the Vanguard program, showing how consideration of these different aspects of success sheds light on the program and its aftermath. We consider the implications of the framework for the comprehensive and multifaceted evaluation of policy pilots.  相似文献

Race/ethnicity, citizenship status, and trauma, have significant impact on delinquency and crime outcomes; though the reasons for some expected and unexpected crime pathways are still unanswered. Using data from the National Longitudinal Survey of Youth 1997 (n?=?7,103), this study found the following results: no difference in the likelihood of engagement in delinquency and crime between blacks and whites; cumulative trauma increased delinquency and crime rates for all racial and ethnic groups; racial and ethnic minority groups compared to whites reported a significantly higher level of childhood trauma experiences; and native-born female immigrant groups (but not male) were more likely to engage in delinquency and crime than first-generation female immigrant groups. Implications and recommendations are set forth.  相似文献

In this article, we consider the phenomenon of message crimes involving harm to wildlife from a sociological and criminological perspective. Using a case study of dissident Nordic hunters killing protected wolves to send a message to the state agencies responsible for their conservation, we engage philosophically with the question of wildlife victimhood and why interspecies violence is unjustifiable as a mode of political dissent. As an alternative to the species justice perspective in green criminology, we examine how the acts disrespect animals as moral subjects of public communication and frustrate dialogue regarding what is owed to them in terms of political justice.  相似文献

The sixth MDG aims 'to combat HIV/AIDS, TB, malaria and other diseases'. The residual category of 'other diseases' has become the focus of intense interest, partly because it has provided an opportunity to increase resources for the control of the mostly parasitic 'neglected tropical diseases' (NTDs). Intense lobbying has secured large amounts of funding from donors, as well as generous donations of medicines from the major drug companies. A massive programme is now underway to treat the parasites of the poor in Africa via integrated vertical interventions of mass drug administration in endemic areas. The approach has been hailed as remarkably effective, with claims that there is now a real prospect of complete control and, for some NTDs, even elimination. However, a closer look at evaluation and research data reveals that much less is known about what is being achieved than is suggested. Competition between implementing organisations is leading to potentially counterproductive exaggerations about treatment coverage. Detailed local-level research in Uganda and Tanzania shows that actual rates of drug take-up among target populations are often lower than is necessary to effectively control the diseases, and that methods of drug distribution may even lead to active resistance to treatment. If current trends are not corrected, declining rates of NTD infection will not be sustained. Much more rigorous and effective monitoring is essential.  相似文献

Parental dissatisfaction with children appears to be associated with child maltreatment. However, little is known regarding the specific domains of parental dissatisfaction that may increase child maltreatment potential, particularly in perpetrators of child maltreatment where substance abuse is present. In this study, responses to the Child Abuse Potential Inventory (CAPI) and a scale measuring parental satisfaction in 11 domains were examined in a sample of 82 mothers who were referred for treatment of substance abuse and child neglect by the local child protective service agency. Results indicated that mothers were relatively most satisfied with their children overall, and least satisfied in domains that were relevant to discipline (i.e., following house rules, compliance, reaction to redirection and punishment, completion of chores). Five of the 11 areas of parental satisfaction that were assessed evidenced negative correlations with child abuse potential, indicating that as satisfaction increased, abuse potential decreased. However, when correlation analyses excluded participants with elevated CAPI Lie scale scores (a measure of social desirability), only overall happiness demonstrated a significant negative correlation with child abuse potential. These results suggest that while associations are present among measures of parental satisfaction and child abuse potential, these associations are moderated to some extent by social desirability, which may help explain some of the inconsistencies reported in prior studies of parental satisfaction and child maltreatment potential.  相似文献

The Word Memory Test (WMT) is an established symptom validity test that relies on verbal memory performance to make inferences about “effort.” Previous studies, using a functional MRI (fMRI) adaptation of the WMT with healthy controls, have shown that successful completion of the WMT relies on a widespread network of neural systems associated with high cognitive effort. Additional studies using the same fMRI paradigm with patients with severe traumatic brain injury (TBI) suggest that increased activation of cortical regions associated with cognitive load are recruited to meet the cognitive challenges that the WMT places on a compromised neural system. This study builds on previous findings as a result of highly uncommon circumstances in which fMRI data on the WMT task were made available from the very same individual both 1 year before and 1 year after sustaining a TBI. Interestingly, the effect of TBI did not appear to impair performance on the WMT in terms of standard accuracy measurements, though response times were notably slower. The main fMRI finding was a significantly stronger and more widespread pattern of activation post-injury, particularly in the frontal and parietal brain regions, suggesting that stronger engagement of these networks was necessary to sustain accurate WMT performance compared to pre-injury testing. This unique source of data, together with previous findings, suggests a more complex relationship between effort and performance levels on the WMT than what is commonly assumed.  相似文献

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.  相似文献

Purpose

Sexual aggression on college campuses has received a great deal of research attention. Little criminological theory, however, has systematically linked individual-level risk factors for sexual aggression with broader societal factors like patriarchy. DeKeseredy and Schwartz (1993) proposed that societal patriarchy is translated into individual attitudes of male sexual proprietariness and entitlement, which provide motivation and justifications for sexual violence.

Methods

This study explored the concept of entitlement through various measures and demonstrated the utility of the concept by linking it with other theoretically-relevant variables, including self-control, sexual partners, use of pornography, adversarial sexual beliefs, and rape myth adherence.

Results

Entitlement was significantly correlated with theoretically-relevant variables in the expected directions. Additionally, entitlement was able to distinguish sexually aggressive and nonaggressive men. Multivariate models provided support for the theoretical assertion that entitlement fosters rape-supportive attitudes and behaviors, which in turn was related to sexual aggression.

Conclusions

Entitlement is an important concept in understanding sexual aggression, and the causal relationships implied by theory should be explored further in future research. Implications and directions for future research and theory are discussed.  相似文献
