The Public Services (Social Value) Act 2012 introduces a social value duty. It requires public authorities in England and Wales that are carrying out procurement activities to ‘consider’ how such activities might ‘improve … economic, social and environmental well-being’. This article analyses qualitative, empirical data on how the social value duty has been interpreted and applied across local government in England. Although only a weak legal duty, this law has made a notable impact on practice. The article explains the changes brought about in practice under the social value duty and seeks to understand why these changes have occurred. It does so by recognizing local government procurement markets, as well as local government organizations themselves, as strategic action fields. In these fields, there are competing visions for social value. It is through conversations between actors that a common meaning comes to be attached to the law. 相似文献

Studies of stress consistently have linked individuals’ experiences of stress to maladjustment, but limited attention has been given to cultural stressors commonly experienced by minority individuals. To address this, the current study examined the links between cultural stressors and prospective changes in mental health symptoms in a sample of 710 (49 % female) Mexican American youth. In addition, the moderating role of both family and neighborhood cohesion was examined. In-home interviews were completed with youth, mothers (required) and fathers (optional) to collect data on youth’s experiences of cultural stressors (discrimination and language hassles) and internalizing/externalizing behavior, and mothers’ report of family cohesion and mothers’ and fathers’ report of neighborhood cohesion. Analyses revealed that youth’s experiences of discrimination and language hassles at 5th grade were related positively to increases in internalizing symptoms at 7th grade. Additionally, youths who reported higher levels of language hassles in 5th grade experienced increases in externalizing symptoms across the 2-year span. Both family and neighborhood cohesion emerged as significant moderating factors but their impact was conditional on youth’s gender and nativity. Limitations and future implications are discussed. 相似文献

Conventional wisdom argues that national economic perceptions generally have an important impact on the vote choice in democracies. Recently, a revisionist view has arisen, contending that this link, regularly observed in election surveys, is mostly spurious. According to the argument, partisanship distorts economic perception, thereby substantially exaggerating the real vote connection. These causality issues have not been much investigated empirically, despite their critical importance. Utilizing primarily American, and secondarily British and Canadian, election panel surveys, we confront directly questions of the time dynamic and independent variable exogeneity. We find, after all, economics clearly matters for the vote. Indeed, once these causality concerns are properly taken into account, the impact of economic perceptions emerges as larger than previously thought. As well, the actual impact of partisanship is clearly reduced. 相似文献

Explaining the Consequences of Imprisonment for Union Formation and Dissolution in Denmark 下载免费PDF全文
Crime and subsequent imprisonment reduces men's chances on the marriage market and increases their divorce risk, but existing research, with a few notable exceptions, is silent about the underlying mechanisms driving these effects. This article studies the effect of home confinement under electronic monitoring as a noncustodial alternative to imprisonment on the risk of relationship dissolution and being single, thereby distinguishing between effects of incarceration and of committing crime. We study a policy that expanded the use of electronic monitoring to address nonrandom selection into electronic monitoring instead of in prison. Results from a sample of 4,522 men show that home confinement under electronic monitoring significantly and persistently lowers the risk both of being single and of becoming single during the first five years following conviction. The results show that one of the tools that could promote decarceration trends also secures better relationship outcomes of convicted men. 相似文献
