The 2030 Agenda for Sustainable Development promotes multi‐stakeholder partnerships (MSPs) as a means of implementation while at the same time putting renewed focus on the need for national‐level ownership and implementation. Despite the fact that an ever growing body of literature on the merits and drawbacks of MSPs delineates several success conditions for partnerships, efforts to translate this knowledge into national‐level meta‐governance for MSPs remain marginal to date. This study outlines the benefits the literature alleges for such “meta‐governance” frameworks, before it uses a country‐level study with a series of stakeholder interviews to take a closer look at national‐level context conditions and lessons learned with regard to two water partnerships in Kenya. Our findings suggest that to date the existing meta‐governance for partnerships in Kenya is rather weak and fragmented. Yet respondents support the view that MSPs could benefit from such a framework, in particular regarding local ownership of MSPs and the potential to scale successful cases.

For the last two decades, performance management theories and practices have focused on outcome‐oriented management but have paid little attention to the role of public communication. Using multiple large data sets from Kansas City, Missouri, for 2009–14, this research suggests that the perceived effectiveness of public communication has a more substantial impact on public satisfaction with police protection and crime prevention than neighborhood crime rates and broken windows factors and that perceived effectiveness moderates the negative impact of crime rates. After controlling for residents’ demographic characteristics, the authors find that the perceived effectiveness of communication is associated with public satisfaction with the content and quality of the city website and the government television channel. The implications for public safety management and police–citizen relations as well as directions for future research on public communication strategies and public performance management are presented.  相似文献

Individuals are the single largest source of campaign contributions, yet we know little about their motivations. For instance, the existing literature questions whether individual contributors sophisticatedly differentiate among candidates according to policy positions, particularly among same‐party candidates. We analyze this issue by combining data from a new survey of over 2,800 in‐ and out‐of‐state donors associated with the 2012 Senate elections, FEC data on contributors’ professions, and legislative records. Three major findings emerge. First, policy agreement between a donor's positions and a senator's roll calls significantly influences the likelihood of giving, even for same‐party contributors. Second, there is a significant effect of committee membership corresponding to a donor's occupation; this holds even for donors who claim that other motivations dominate, but it does not appear to be motivated by an expectation of access. Third, conditional upon a donation occurring, its size is determined by factors outside a legislator's control.  相似文献

We evaluate changes in elementary school children health outcomes following the introduction of California's Paid Family Leave (PFL) program, which provided parents with paid time off following the birth of a child. Our health outcomes—overweight, ADHD, and hearing‐related problems—are characterized by diagnosis rates that only pick up during early elementary school. Moreover, our health outcomes have been found to be negatively linked with many potential implications of extended maternity leave—increased breastfeeding, prompt medical checkups at infancy, reduced prenatal stress, and reduced non‐parental care during infancy. Using the Early Childhood Longitudinal Studies (ECLS) within a difference‐in‐differences framework, our results suggest improvements in health outcomes among California elementary school children following PFL's introduction. Furthermore, the improvements are driven by children from less advantaged backgrounds, which is consistent with the notion that California's PFL had the greatest effect on leave‐taking duration after childbirth mostly for less advantaged mothers who previously could not afford to take unpaid leave.  相似文献

Drawing on institutional theory, this article articulates qualitative insights from a program of research on Canadian health technology‐based ventures to examine the rules that characterize economic policy, capital investment, and regulatory approval as well as the way these institutions enable and constrain the development of ventures at an early stage. Our findings clarify how economic policy integrates these ventures into the entrepreneurial domain, how capital investment configures them for economic value extraction, and how regulatory approval fully releases their market value. These findings help to revisit current policy modernization initiatives by calling attention to the convergence among the three institutions. Rather than operating solely as a source of constraints, these institutions provide a highly integrated market‐oriented space for health technology‐based entrepreneurial activities to unfold.  相似文献

Regulatory reforms to public infrastructure services across European Union (EU) countries were aimed at increasing consumer welfare by introducing competition and choice into service markets. However, empirical evaluations have questioned whether these reforms have benefitted all consumers, suggesting that vulnerable groups of service users (especially those with lower levels of formal education), might be locked into poorly performing services. We assess the relationship between the level of competition in electricity and fixed telephony markets in EU countries and evaluate the affordability of these services for different socio‐educational layers. Our findings show that – although in countries where there is a relatively high frequency of switching, inequalities between socio‐educational groups are smaller and eventually disappear – competition as such does not play a part. These results suggest that demand‐side regulation that successfully enables consumer switching has the potential to equalize social welfare, thereby reflecting a possible convergence of regulatory instruments and the central aims of the welfare state in this context.  相似文献

Responsiveness and accountability constitute the process of democratic representation, reinforcing each other. Responsiveness asks elected representatives to adopt policies ex ante preferred by citizens, while accountability consists of the people's ex post sanctioning of the representatives based on policy outcomes. However, the regulatory literature tends to interpret responsiveness narrowly between a regulator and regulatees: the regulator is responsive to regulatees’ compliance without considering broader public needs and preferences. Democratic regulatory responsiveness requires that the regulator should be responsive to the people, not just regulatees. We address this theoretical gap by pointing out the perils of regulatory capture and advancing John Braithwaite's idea of tripartism as a remedy. We draw out two conditions of democratic regulatory responsiveness from Philip Selznick – comprehensiveness and proactiveness. We then propose overlapping networked responsiveness based on indirect reciprocity among various stakeholders. This mechanism is the key to connecting regulatory responsiveness with accountability.  相似文献

Although research consistently suggests that adolescents in single-mother families are at increased risk for depression, the mechanisms that explain this relationship are unclear. In a community sample of adolescents (N?=?368; ages 12–16; 50?% female; 50?% White) and their mothers (42?% single), adolescents completed measures of depressive symptoms, rumination, and depressogenic inferential style at baseline and two yearly follow-ups. Mothers reported on stressful events that occurred in the child’s life from birth until baseline. Adolescents raised by single mothers, relative to partnered mothers, experienced more childhood stressors and higher rumination levels at 1-year follow-up. Additionally, higher rumination mediated the relationship between single motherhood and greater youth depressive symptoms at the 2-year follow-up. Clinical implications and developmental considerations are discussed.  相似文献
