THE RELATIVE EFFICIENCY OF CHARTER SCHOOLS   总被引:1,自引:0,他引:1  
ABSTRACT ** :  This analysis compares the technical efficiency of charter school primary and secondary campuses with that of comparable campuses in traditional Texas school districts. Charter schools are hybrids—publicly funded, but not required to meet all the state regulations releant for traditional schools. Student performance is measured using value added on standardized tests in reading and mathematics, and efficiency is measured using the input distance function. The analysis suggests that at least in Texas, charter schools are substantially more efficient than traditional public schools.  相似文献

This article explores the use of Electronic Monitoring (EM) in homecare and its impact on the ratio of paid to unpaid working time. It argues that whilst Zero Hours Contracts (ZHCs) blur the distinction between paid and unpaid labour, the introduction of EM can formalise and regulate the demarcation between the two. In the context of local authority commissioning and constrained budgets, the combination of EM and ZHC's may excise so‐called ‘unproductive’ but available labour from homecare. In particular, the minute‐by‐minute commissioning of care that EM facilitates means the cost of homecare is anchored in the time that worker's spend in client's houses, squeezing out paid travel, time between visits, training and supervision. Paid working time is minimised whilst maximising the use of unpaid time with resulting intensification of care labour.  相似文献

ABSTRACT

Tourism education has the power to transform how students see and think about tourism and, ultimately, how they act within and for tourism. Yet students are likely to have different outcomes depending on the curriculum space(s) they journey through. In this article, I present a Reflective Topical Autobiography that explores the ways in which my praxis has been shaped and moulded by tourism education. Drawing on my experiences of journeying through three different curriculum spaces, I will illustrate the dynamic relationship that exists between the curriculum, pedagogy and learning. In doing so, I aim to further elucidate the benefits associated with values-based teaching and learning.  相似文献

The dominant supply-side foundation for explanations of the growth potential of an economy is losing its persuasive power in the face of persistent losses in output and employment experienced by mature economies in the aftermath of the financial crisis. There is now an opening for eclectic approaches that consider the interaction between supply-side and demand-side factors in shaping macroeconomic outcomes. In this paper, we develop a model that reflects such an approach to interpreting differential productivity growth over the long run, and then present empirical results for several countries. On the supply-side, the model considers the linkage between the intensity and efficacy of the accumulation process and the gains of productivity in terms of a Kaldorian Technical Progress Function. Then, drawing on the Evsey Domar's Keynesian notion of dynamic equilibrium as the growth rate that reconciles additions to capacity with the absorption of aggregate output by demand, we derive a locus for a ‘Domar equilibrium path’. Imbalances caused by excess aggregate supply or demand, and by the effects of ‘shocks’ are presented and discussed using a simple graphical framework. In the empirical analysis, an error-correction model is applied to the fundamental relationship between the rate of growth of product per work-hour and the rate of capital accumulation. The results suggest that the differences in productivity growth among countries are can be explained in terms of the efficiency of their ‘accumulation paths’.  相似文献

An extensive body of safety literature and research discusses the integral role of rules and procedures in managing workplace hazards, ensuring worker safety, and safeguarding the environment. Nevertheless, organizational accidents and workplace injuries continue to occur, and individual employees often bear the brunt of responsibility. This paper examines how risk becomes shifted to individuals at the bottom of supply chains, focusing on two different groups of contract workers. Specifically, it draws on case studies conducted in Australia – one on civil contractors working around hazardous infrastructure and one on athletes who are subject to anti-doping requirements. A comparison of the two cases and their distinctive elements illuminates the ways in which structural pressures, organizational dynamics, and context-specific conditions influence the risks shouldered by individuals. Our analysis shows that, in both cases, adverse outcomes are widely seen as the responsibility of contract workers, prompting other actors to judge them as blameworthy. In doing so, risk in various forms (e.g. safety, financial, reputational) becomes shifted onto workers who are constrained by contracts and away from away from higher level actors and organizations that are generally in more powerful positions than frontline workers. This finding suggests that the burden of accountability and potentially liability is borne primarily by frontline workers. Because of this focus, it is easy to lose sight of organizational and structural conditions that contribute to the risks revealed at the individual level. Through an analysis of 57 interviews across both sectors, complemented by participant observations and a media review, this paper underscores the importance of critically considering not only individual worker actions, but also how regulation can support the diversion of risk, responsibility, and liability onto frontline workers.  相似文献

Ongoing safe operation of hazardous industries such as hydrocarbon production and transportation, air traffic control and nuclear power generation depends on effective decision-making by those in key positions. Safety studies often focus on the extent to which actions of operational personnel in particular are dictated by procedures or rules and hence reinforce the need for compliance to ensure the best outcomes. This article directs attention to a different area – the judgements made by experts in the cases that are not covered by rules and, in particular, the key role of stories and storytelling. This ethnographic research draws on literature related to high-reliability theory, organisational learning and naturalistic decision-making to examine how experts working in diverse critical contexts use stories to share and make sense of their experiences. It argues that such stories are vital to effective decision-making as a result of both the general and specific lessons that they embody. Our analysis shows that experts use stories as parables to nurture their ability to imagine possible outcomes and maintain a safety imagination. Stories are also embedded in work practices to support decision-making in the moment. Finally, stories are strongly linked to organisational learning for experts as a group and in mentoring less-experienced colleagues. We argue that the increased focus on incident reporting systems in hazardous industries, which is driven at least in part by a consideration of organisational learning, is failing in this regard because such systems do not facilitate story-based learning. We appeal to organisations to support story-based learning with as much vigour as formal systems for professional development and reporting.  相似文献

Public relations practitioners are actively building relationships with bloggers to obtain high-credibility brand mentions and reviews. Practitioners may request bloggers limit comments to maintain control over messages and constrain dissonant perspectives; however, the impact of limiting social features of blogs is unknown. Utilizing source credibility and warranting theory, this article examines the relationship between enabled comments on blogs and brand attitudes, with the moderating variables of credibility and expertise, from both a public relations and consumer behavior perspective. Using an online experiment (N = 527) we found that socialness increases perceptions of blogger expertise, brand attitudes, and purchase intention, but not credibility.  相似文献
