The city-state of Singapore is proactive in harnessing policy experimentation to incubate innovations, transfer knowledge and facilitate collaborations across different public sectors. Given the country’s strong knack for pragmatism, international practices and lessons are usually first tested and adapted in policy experiments before scaling up to nationwide policies. Singapore’s practice of policy experimentation, however, has also demonstrated evolution over time. This article reviews the evolving role of experimentation in Singapore’s policy decision-making and implementation, and analyses pilot programmes in public housing to elicit the key attributes and commonalities of its policy experiments. It finds that policy experiments have been increasingly used after the 2011 general election, which witnessed a radical political rebalancing in Singapore’s governance history. Pilot projects have thus transformed from a utilitarian to citizen-centric, design-thinking approach after 2011. Pilot programmes are used for multiple purposes in policy innovations, among which civil service mentoring, knowledge transfer and cross-boundary collaboration are the values primarily pursued. The article discusses the contributions of the findings to the literature and policy implications for practitioners.  相似文献

Crime victim–police interface and registration of crime are the early and fundamental interactions in the criminal justice system. The process of lodging a complaint is marked by the pain of victimization, sharing of information, and expectation of quick remedial action from the police. The nature and quality of experience of the victim and outcomes impact the level of satisfaction with services of police. Through a survey of victims of property crimes, in different areas of a state in India, the author examines the impact of procedural justice and outcomes on victim satisfaction. The study illuminates the outcome oriented expectations of the victim, and the unique dynamics of victim–police interaction, which strains the legal ethical framework of the criminal justice system.  相似文献

Jones, Hesterly and Borgatti (1997) proposed a general theory of network governance (GTNG), identifying conditions under which network governance is likely to develop and detailing four social mechanisms that protect and promote resource exchange and collaborative action within a network. This article applies their theory to the emerging problem of swatting—internet-based spoofing attacks that compel a SWAT response to a selected innocent victim. As this problem has not been addressed through traditional policy or law enforcement mechanisms, networks have emerged to respond to these attacks. The author details the parallels between these emergent networks and Jones et al.’s theoretical framework.  相似文献

Although the relation between family relationships and the timing of sexual debut has been the focus of many studies, research on mediating factors is scarce. This study examines whether low levels of family cohesion result in an earlier onset of romantic and sexual experiences, and whether the link between family cohesion and an early sexual debut is mediated by early romantic initiation. A longitudinal sample of 314 adolescent girls and 222 boys, aged 12–17 at Wave 1, completed questionnaires at three measurement points with three year intervals. The results showed that sexual debut followed romantic initiation for 77% of the participants. For early adolescent females (aged 12–14), high levels of family cohesion resulted in a later sexual debut and this association was fully mediated by a delay of romantic initiation. Among boys and older girls, timing of romantic initiation did not mediate the link between family cohesion and timing of sexual initiation. Early adolescent girls who have negative relationships with their parents turn to romantic relationships for intimacy and support, which subsequently provide the opportunity for an early sexual debut. Low levels of family cohesion thus primarily precipitate romantic initiation and sexual initiation appears to be secondary to this process among girls in this age group.  相似文献

Youth who participate in service activities differ from those who do not on a number of key demographic characteristics like socio-economic status and other indicators of risk; and most studies demonstrating positive outcomes among service participants employ small non-representative samples. Thus, there is little evidence as to whether the outcomes associated with service participation are similar among students with varying levels of risk. The National Household Education Survey of 1999, a large nationally representative cross-sectional data set that focused on community service, was analyzed to investigate associations between the risk status of 4,306 adolescent students (50.2% female; 63.3% European American, M age?=?15.9), their participation in community service, and their academic adjustment, behavioral problems, and civic knowledge. Because adolescents who participate in service differ from those who do not with respect to demographic characteristics, propensity score analyses were used to correct for potential selection bias in the examination of these relationships. Analyses tested competing theoretical models of service??protective versus compensatory??among students at varying levels of risk, and suggested that service acts as a compensatory factor with respect to academic, behavioral, and civic outcomes. Propensity score analyses revealed patterns suggesting that, in some cases, students with certain demographic profiles that are themselves related to the likelihood of service participation may benefit from service participation more than others. Findings are discussed in terms of their significance for adolescent development, for planning service programs, and for educational policy.  相似文献

When people talk about their lives, people lie sometimes, forget a little, exaggerate, become confused, and get things wrong. Yet they are revealing truths … the guiding principle for [life histories] could be that all autobiographical memory is true: it is up to the interpreter to discover in which sense, where, and for what purpose.

Sipping alcohol during childhood may be a marker of differentiation as regards children’s future risk of underage drinking; yet very little is known about alcohol use when it occurs among elementary school-aged children. The purpose of the present study is to examine alcohol sipping behavior in a sample of third-grade school children to learn whether sipping is associated with attributes that could increase children’s likelihood of further underage drinking. We collected telephone interview data from 1,050 mothers and their third grade children (mean age 9.2 years; 48.2 % male) residing in the Southeastern United States. The majority of mothers were White non-Hispanic (69.02 %) or Black non-Hispanic (21.3 %); most (85 %) lived in households shared with fathers or other adult caretakers. We hypothesized that children who sip alcohol would score lower than abstinent peers on indicators of competence and score higher on indicators of exposure to alcohol-specific socialization by parents and peers. A multivariate model controlling for frequency of parent alcohol use and demographic covariates showed that children who had sipped alcohol were significantly less likely than abstinent peers to affirm indicators of competence and significantly more likely to affirm indicators of exposure to alcohol specific socialization by parents and by same age peers. These preliminary findings suggest that developmental attributes associated with risk of underage drinking begin to differentiate at least as young as middle childhood. Research is needed to test prospectively for continuity between alcohol risk attributes present in middle childhood and future alcohol use.  相似文献
