In recent times, the UK has witnessed a steady growth in the use of agency workers to fill core professional roles in public sector organizations. Similar trends have been noted elsewhere, particularly in Australia and the US. In this paper our objective is to explore some of the consequences of this growth, drawing on case study research on social services. We point to a number of problems associated with the management of agency workers and to the potentially negative consequences for the quality of services. These problems, in turn, may impact on key aspects of a (largely functional) public service employment model founded on strong internal labour markets, employment stability and collegial ethos. We also note that while there are ways in which public organizations can manage this situation, certain constraints may prevent them from doing so.  相似文献

The J Curve     
Globalization may yet repeal the Biblical adage that the poor will always be with us. But for now there are enough losers to go along with the winners that a slide back toward fragmentation and protectionism is a distinct possibility, as was also the case at the turn of the 20th century. Our contributors in this section offer their advice on how to make globalization work for everyone.  相似文献

If the 20th Century was the century of physics, the 21st Century is the century of cybernetics, biology and ecology. Technological advance has both crossed new frontiers and discovered old limits. Nobel laureate Ilya Prigogine broke new ground with his understanding that nature, including its human component, seeks to establish order out of chaos by “self‐organizing,” not only according to pre‐determined laws, but through random creative choices as well that are responsible for the endless novelty and potentiality of being. The technologically‐armed purposive role of humans in the Anthropocentric Age thus takes on a new significance: “What we do today depends on our image of the future rather than the future depending on what we do today” as Prigogine puts it. “The equations of the future are written in our actions as well as in nature. Time becomes construction.” Nowhere is this truer than in the new science of genomics, which touches the soul, and in the effort to preserve the ecological balance that has enabled humanity to flourish within the narrow band of earth's livable climate. In this section we bring together leading thinkers, scientists and technologists of our age to address these issues of mankind's fate.  相似文献

Existing studies have generally measured collective efficacy by combining survey respondents’ ratings of their local area into an overall summary for each neighborhood. Naturally, this approach results in a substantive focus on the variation in average levels of collective efficacy between neighborhoods. In this article, we focus on the variation in consensus of collective efficacy judgments. To account for differential consensus among neighborhoods, we use a mixed‐effects location‐scale model, with variability in the consensus of judgments treated as an additional neighborhood‐level random effect. Our results show that neighborhoods in London differ, not just in their average levels of collective efficacy but also in the extent to which residents agree with one another in their assessments. In accord with findings for U.S. cities, our results show that consensus in collective efficacy assessments is affected by the ethnic composition of neighborhoods. Additionally, we show that heterogeneity in collective efficacy assessments is consequential, with higher levels of criminal victimization, worry about crime, and risk avoidance behavior in areas where collective efficacy consensus is low.  相似文献
