The use and non-use of policy appraisal tools in public policy making: an analysis of three European countries and the European Union 总被引:1,自引:0,他引:1

The increasing complexity of policy problems, coupled with the political desire to base new policies on the foundation of firm evidence, has accelerated the development of policy assessment tools. These range from complex computer models and cost benefit analysis through simple checklists and decision trees. In the last decade, many governments have established formal policy assessment systems to harness these tools in order to facilitate more evidence-based policy making. These tools are potentially widely available, but to what extent are they used by policy makers and what becomes of the evidence that they generate? This paper addresses these questions by studying the empirical patterns of tool use across 37 cases in three European countries and the European Commission. It uses a simple classification of tools into advanced, formal and simple types. It finds that even when tools are embedded in policy assessment systems, their use is differentiated and on the whole very limited, in particular when it comes to more advanced tools. It then explores these patterns from contrasting theoretical perspectives to shed light on why, when and how different policy assessment tools are used in the policy process. 相似文献

The Bully-Sexual Violence Pathway theory has indicated that bullying perpetration predicts sexual violence perpetration among males and females over time in middle school, and that homophobic name-calling perpetration moderates that association among males. In this study, the Bully-Sexual Violence Pathway theory was tested across early to late adolescence. Participants included 3549 students from four Midwestern middle schools and six high schools. Surveys were administered across six time points from Spring 2008 to Spring 2013. At baseline, the sample was 32.2% White, 46.2% African American, 5.4% Hispanic, and 10.2% other. The sample was 50.2% female. The findings reveal that late middle school homophobic name-calling perpetration increased the odds of perpetrating sexual violence in high school among early middle school bullying male and female perpetrators, while homophobic name-calling victimization decreased the odds of high school sexual violence perpetration among females. The prevention of bullying and homophobic name-calling in middle school may prevent later sexual violence perpetration. 相似文献

Adolescents who do not conform to weight ideals are vulnerable to disapproval and victimization from peers in school. But, missing from the literature is a prospective examination of weight status and feelings of loneliness that might come from those experiences. Using data from the Québec Longitudinal Study of Child Development, we filled that gap by examining the prospective associations between loneliness and weight status when the sample was aged 10–13 years. At ages 10, 12, and 13 years, 1042 youth (572 females; 92% from French speaking homes) reported on their loneliness and were weighed and measured. Family income sufficiency was included in our analyses given its relationship with weight status, but also its possible link with loneliness during early adolescence. The findings showed that (1) weight status and loneliness were not associated concurrently; (2) weight status predicted increases in loneliness from ages 12 to 13 years; and (3) loneliness predicted increases in weight from ages 12 to 13 years among female adolescents, but weight loss among male adolescents. The fact that loneliness was involved in weight gain for females suggests that interventions focused on reducing loneliness and increasing connection with peers during early adolescence could help in reducing obesity. 相似文献

Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy. 相似文献

ABSTRACTThe authors draw on two competing cultural perspectives—culture as values and culture in action—to examine the relationship between street codes and the propensity to violently victimize others. Specifically, they explore whether individual-level and school-level street codes, net of one another, are related to 3 types of violence: assault, robbery, and sexual battery. In addition, they consider whether these effects vary according to 3 contextual characteristics: (a) the location of the offending—in school versus out of school, (b) school-level economic disadvantage, and (c) school efficacy. Three-level ordinal logistic regression models are estimated using four waves of survey data from over 3,000 students nested within 103 schools. Results provide evidence that individual-level street codes are related to violent offending in a manner that is, largely speaking, not tied to context. However, there is some evidence that the effects of school-level street codes on offending differ between outside of school and in school settings and are conditioned by levels of school disadvantage and efficacy. Overall, some support is offered for both the culture-as-values and culture-in-action perspectives. 相似文献

Based on anthropological field work in southeastern Nigeria, this paper explores the public concerns and everyday experience of corruption in a society still living with the legacies of the Biafran secession attempt. The paper shows how the revival of Igbo nationalism and resentment over perceived marginalisation is fuelled by perceptions that the corrupt machinery of the federal government runs against the interests of the Igbo people, and funnels resources away from the southeast as punishment for the failed separatist struggle more than 40 years ago. Hence, complaints about corruption are used to critique the Nigerian state and other regional or ethnic groups, but they also figure in an internally focused critique by Igbos of their own complicity in Nigeria’s endemic corruption. 相似文献

Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via “cyber dating abuse.” Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon’s limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths’ individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52 % female, 74 % White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one’s lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse. 相似文献

Although impulsivity is one of the strongest psychological predictors of crime, it is unclear how well impulsivity, measured at a specific moment in adolescence, predicts criminal behavior months or years into the future. The present study investigated how far into the future self-reports and parents’ reports of a youth’s impulsivity predicted whether he engaged in illegal behavior, whether one reporter’s assessment was more predictive than the other’s, and whether there is value in obtaining multiple reports. Data were obtained from a 6-year longitudinal study of adjudicated juvenile offenders (n = 701 mother-son dyads). Youth (m = 15.93 years old; sd = 1.14) and their mothers independently reported on adolescents’ impulsivity at the initial assessment. We examined the prospective correlation of these measures with illegal behavior, assessed by official records of arrests and youths’ self-reports of offending across the 72-month study period. Youths’ and mothers’ reports of the adolescents’ impulsivity were weakly, but significantly, correlated with one another. Furthermore, mothers’ ratings of their sons’ impulsivity predicted arrest up to 6 years into the future, whereas youths’ reports did not significantly predict arrest beyond 30 months. With respect to youths’ self-reports of offending, mothers’ ratings of impulsivity again predicted farther into the future (as late as 6 years later) than did youths’ self-reports of impulsivity, which were not predictive beyond 4 years. However, across the first 4 years, youths’ self-reports of impulsivity explained more variance in self-reported offending than did mothers’ ratings. The results underscore the endurance of the predictive utility of an assessment of impulsivity and the importance (and accuracy) of parents’ reports of developmental constructs, even when their children are adolescents. 相似文献
