An Erratum has been published for this article in Public Administration and Development 22(1) 2002, 95. In commenting on ‘Decentralization, Local Governance and ‘Recentralization’ in Africa’ (Wunsch, 2001 ), this article concurs with the general thesis of Wunsch that the actual implementation as distinct from the rhetoric of decentralization in Africa has featured lingering central retention of power and resources and that genuine local control over important services and investments remains elusive. However, there is evidence that this is not invariably the case and that donors may have decisive roles to play in encouraging local assertiveness in the medium term in providing leverage for change through budget support and technical assistance to civic education, training local councillors, monitoring local government elections and encouraging local government associations to put to the test the national commitment to genuine local governance. These roles include helping to ensure the transparency of central transfers and, as in Uganda and Malawi for example, assisting with the development of intermediary fiscal mechanisms in this regard. Learning from such promising experiences will be vital in nurturing the longer term optimism heralded by Wunsch. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Using data from a national sample of 388 Latino young adolescents, this study identified the social-demographic characteristics, influences in the broader social environment, and parenting practices that predict youth academic achievement. Youths who were Mexican American, older, and had an English language problem had lower levels of reading and mathematics achievement. Youths of mothers who began childbearing at older ages, had higher levels of intellectual abilities, and reported no English language problem scored better on both types of achievement tests, but poverty was related only to reading achievement. Attendance in higher-rated schools was associated with higher reading and mathematics scores, but residence in better quality neighborhoods was related only to reading achievement. Three parenting practices—providing cognitive stimulation, parent–youth conflict, and academic involvement—predicted both types of achievement. The effect of poverty on reading achievement was explained by residence in lower quality neighborhoods, lower levels of cognitive stimulation, and parent–youth conflict.Associate Professor, University of Illinois at Urbana-Champaign.

This article critically reviews the literature about adolescent males’ sexuality in order to describe the state of the science and to identify promising concepts and research designs that have the potential to guide the next generation of research. A critique was conducted on 94 peer-reviewed studies of sexual behaviors that included a sample of adolescent males; 11 scholarly texts and 2 dissertations. Most studies lacked a theoretical foundation and had cross-sectional designs. For those studies with a theoretical base, 3 perspectives were most often used to guide research: cognitive, biological, or social-environmental. Studies frequently relied on older adolescents or young adult males to report behaviors during early adolescence. Male-only samples were infrequent. Findings include (a) the measurement of sexual activity is frequently limited to coitus and does not explore other forms of “sex”; (b) cognitive factors have been limited to knowledge, attitudes, and intent; (c) little is known about younger males based on their own self-reports; (d) little is known about the normative sexuality development of gay adolescent males; and (e) longitudinal studies did not take into account the complexities of biological, social, and emotional development in interaction with other influences. Research on adolescent sexuality generally is about sexual activity, with little research that includes cognitive competency or young males’ sense of self as a sexual being. The purpose of the paper is to critically review the literature about male sexuality in order to describe the state of the science as well as to identify potential directions to guide the next generation of adolescent male sexual being research.Assistant Professor in the School of Nursing at Oakland University.

Hot spots policing and crime prevention: A systematic review of randomized controlled trials 总被引:1,自引:0,他引:1
Crime scholars and practitioners have argued that police actions should be focused on high-risk crime places rather than spread thinly across the urban landscape. This review examines five randomized controlled trials of the effects of concentrating police enforcement efforts on crime hot spots. The findings of these evaluations suggest that focused police actions can prevent crime and disorder in crime hot spots. A meta-analysis of the effect sizes from the five experiments reveals a statistically significant mean effect size for hot spots policing interventions; this suggests overall reductions in citizen calls for service in the treatment hot spots relative to the control hot spots. These studies also suggest that focused police actions at specific locations do not necessarily result in crime displacement. Although these evaluations reveal that these programs work in preventing crime, additional research is needed to unravel other important policy-relevant issues such as community reaction to focused police enforcement efforts. 相似文献

When states in northern Nigeria started processes for implementing Sharia laws in 1999, it triggered sentiments all over the country. In Kaduna State, the proposal led to demonstrations and violent clashes. The article examines the ways in which different scales of politics are mutually constituted in the Sharia case and how the Sharia proposal subsequently resulted in clashes in Kaduna. It is argued that the Sharia initiative, even though it started as a sub-national question, was connected to a national power contestation. However, the federal government remained passive and diverted the issue to local political space. In Kaduna, the issue took dimensions that incurred with apprehensive local political contention that made it escalate into violence and polarising people according to religion. An analysis of the crisis in Kaduna is offered that does not regard the conflict as locally confined, but as inherently related to wider political and historical processes. 相似文献

Open primaries create the possibility of strategic crossover voting. On his March 3, 2008 program and subsequent broadcasts, radio personality Rush Limbaugh called on his listeners to extend the Democratic presidential contest by crossing over to vote for Sen. Hillary Clinton. Using voter registration data from North Carolina and election return data from Indiana, North Carolina, and Pennsylvania (states with open, semi-closed, and closed primaries, respectively), I find no evidence of a Limbaugh-motivated switch in political party registration or of a large or statistically significant Limbaugh-motivated increase in voting for Sen. Clinton. 相似文献

As students transition to post-secondary education, they experience considerable stress and declines in academic performance.
Perceived social support is thought to improve academic achievement by reducing stress. Longitudinal designs with three or
more waves are needed in this area because they permit stronger causal inferences and help disentangle the direction of relationships.
This study uses a cross-lagged panel and a bivariate growth curve analysis with a three-wave longitudinal design. Participants
include 10,445 students (56% female; 12.6% born outside of Canada) transitioning to post-secondary education from ages 15–19.
Self-report measures of academic achievement and a generalized measure of perceived social support were used. An increase
in average relative standing in academic achievement predicted an increase in average relative standing on perceived social
support 2 years later, but the reverse was not true. High levels of perceived social support at age 15 did not protect against
declines in academic achievement over time. In sum, perceived social support appears to have no bearing on adolescents’ future
academic performance, despite commonly held assumptions of its importance. 相似文献

Efficacy of an Intervention to Reduce the Use of Media Violence and Aggression: An Experimental Evaluation with Adolescents in Germany 总被引:1,自引:0,他引:1
Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression
over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills
is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression
in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1% girls) were
assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence
and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2).
The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group.
Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression
and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of
initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression.
No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce
changes in the use of media violence, aggressive norms, and behaviors sustained over several months. 相似文献

AbstractWe examine credit constraint differentials between male and female manufacturing entrepreneurs using firm data from 16 sub-Saharan Africa countries. Small enterprises owned by female entrepreneurs are less likely to be credit constrained compared to their male counterparts, while this is reversed for medium-sized enterprises. A generalised Oaxaca–Blinder decomposition shows that the gap is predominantly a pure gender effect. We argue that this finding is mainly due to female favouritism in loans to micro and small firms because the gap is reversed for medium-sized enterprises and because we find no sign of superior female entrepreneurial performance in observable indicators. 相似文献

In this article, results from self-report studies in two Finnish cities, Helsinki and Turku, are presented. The aims are to compare the prevalence of youth crime between these cities and changes in delinquency during the observation period. In Helsinki, the surveys took place in 1992, 2006 and 2013, and in Turku, the surveys took place in 1992, 2001, and 2013. With the exception of the Turku 2001 survey, all datasets have been collected under the auspices of the International Self-Report Delinquency Study (ISRD). The most recent survey, ISRD3, targeted comprehensive school pupils from grades 7–9 (ages 13–16), while some of the former studies excluded 7th and/or 8th grades. The results show that (1) the delinquency rates are generally higher in Helsinki than in Turku and (2) the prevalence of both property- and violence-related crimes has decreased, while drug use manifested fluctuating or increasing trends. Overall, the findings are consistent with the observation that there has been a relatively general crime drop in the Western world since the 1990s. 相似文献
