Governments have historically offered their workforce a public service bargain founded on stable pay and conditions and job security. However, while the Westminster system aims for public service employment to be protected from the whims of government, public servants are nonetheless affected by the political environment in which they operate and changes to this bargain can occur with a new government. This paper focuses on a Queensland public service change process that resulted in large‐scale forced redundancies, non‐renewal of temporary contracts, and legislative changes that nullified the provisions in job security, organisational change, and redundancy policies. Using communication as a lens through which to understand leadership, it examines how the government communicated with the public service about this organisational change, immediately before and after the 2012 election. In particular, through analysis of public and media commentary, speeches and Hansard records, it examines Premier Newman's change leadership and communication by contrasting pre‐election messages to the public service with post‐election messages about the public service and the justifications for change during this period of downsizing. This analysis is used to reflect on political leadership, communication, fair treatment, and trust in public service change.  相似文献

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

This article seeks to place the UK's present economic ‘moment’ in historical context. Over the course of the decade since the 2007 financial crisis, it has increasingly been acknowledged that a cyclical crisis has become a structural crisis. The failure of most economists to predict the financial crash in the first place, and the inadequacy of economic policy in responding to its lasting effects, has led many to conclude that economics itself is in crisis. This article seeks to contribute to a better understanding of the present period of disjuncture. Drawing on theories of paradigm shift from both the physical and social sciences, we argue that the speed of change in UK economic policy is comparable to the two major historical transitions that ended with the post‐war consensus and neoliberalism. We conclude by offering some remarks on how and where the present change might take us.  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

To examine the infant health impact of prenatal exposure to power plant emissions, we draw scientific evidence on the impacted region downwind of a large polluter, a coal‐fired power plant located on the border of two states and proven to be the sole contributor to the violation of air quality standards of the impacted region. Our results show that among all live singleton births that occurred during 1990 through 2006, those born to mothers living as far as 20 to 30 miles away downwind from the power plant (which is also an affluent region) during pregnancy are at greater risks of low birth weight (LBW) and very low birth weight (VLBW): the likelihoods of LBW and VLBW could increase approximately by 6.50 and 17.12 percent, respectively. In light of the continual efforts of The U.S. Environmental Protection Agency in reducing cross‐state air pollution caused by transboundary power plant emissions, our study is aimed at broadening the scope of cross‐border pollution impact analysis by taking into account adverse infant health effects of upwind polluters, which can impose disproportionate burdens of health risks on downwind states due to air pollutants transported by wind.  相似文献

Why does strategic intelligence analysis have limited influence on American foreign policy? Intelligence analysis is frequently disregarded, this paper contends, because it is a duplicated step in the decision-making process and supplements but does not supplant policy assessment. Many intelligence analyses will confirm policy assessments and be redundant or – if the assessments are different – policy-makers will choose their own interpretations over those of intelligence analysts. The findings of this paper provide scholars with important insights into the limits of intelligence analysis in the foreign policy process as well as recommendations for increasing its positive impact on policy.  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

This article contributes to the growing discourse on the potential of e‐government to transform the operations of public sector institutions, thereby improving public services. It does so by conceptualizing public service quality into efficiency, economy (cost reduction), customer satisfaction, and service accessibility and draws on qualitative data from the Ghanaian narrative for illustration. As previous studies have demonstrated, this study also affirms the potential of e‐government in improving public services delivery by increasing efficiency, reducing the cost of operations, expanding access to services, and achieving customer satisfaction. Yet, there remains a repertoire of challenges such as weak ICT infrastructure especially in towns and villages, incessant power outages and illiteracy, which are drawbacks to fully harnessing the benefits of e‐government in Ghana. The study recommends that these challenges should feature prominently in e‐government policies to increase the chances of solving them.  相似文献
