Increasing the level of school competition has been suggested as a way to improve school performance. This study examines one of the most extreme examples of such reform using data from New Zealand public high schools. In the 1990s school zoning was abolished in New Zealand and public schools competed for students, not just with private schools, but also with each other. A categorical Data Envelopment Analysis model using data on school resources and student academic performance, stratified using student socio-economic characteristics, is used to calculate efficiency scores for schools. A regression model is then used to analyse differences in these efficiency scores and their relationship to different levels of competition.  相似文献

We review current state-of-the-art practices for combining preference data from multiple sources and discuss future research possibilities. A central theme is that any one data source (e.g., a scanner panel source) is often insufficient to support tests of complex theories of choice and decision making. Hence, analysts may need to embrace a wider variety of data types and measurement tools than traditionally have been considered in applied decision making and choice research. We discuss the viability of preference-stationarity assumptions usually made when pooling data, as well as random-utility theory-based approaches for combining data sources. We also discuss types of models and data sources likely to be required to make inferences about and estimate models that describe choice dynamics. The latter discussion is speculative insofar as the body of literature on this topic is small.  相似文献

Food safety regulation: an overview of contemporary issues   总被引:4,自引:0,他引:4  
This article discusses a number of issues that are influencing the evolution of food safety regulation in developed and, to a lesser extent, developing countries. Whilst not definitive, it aims to highlight those factors which are considered crucial to an understanding of contemporary food safety controls in both the public and private spheres. These issues include criteria applied to assess the need/justification for food safety regulation, relationships between public and private food safety control systems, alternative forms that public food safety regulation can take, strategic responses to food safety regulation, and the trade implications of national food safety controls. The article serves as an introduction to these issues, which are discussed at greater length in the other papers that make up this special issue of Food Policy.  相似文献

Valuing the benefits and costs of improved food safety and nutrition   总被引:3,自引:0,他引:3  
Assuring the quality of food products, especially their safety and nutrition levels, is an increasing focus for governments, companies, and international trade bodies. In choosing quality assurance programs, public and private decision-makers must assess the benefits and costs of expected improvements in food safety and nutrition. This article discusses methods for measuring these benefits and costs as well as how these valuations are related to the mix of voluntary and mandatory quality management systems used in particular countries or trading blocs. These relationships are illustrated by a short case study of safety assurance systems for meat and poultry products.  相似文献

Small and medium‐sized enterprises (SMEs) are considered increasingly important for economic growth (Wilson, 1995) and effective management of them is regarded as essential for their survival and success (Jennings and Beaver, 1995). This study adopted a multi‐stakeholder perspective in order to explore the promotion, via Training and Enterprise Councils (TECs); provision and (potential for) purchase of competence‐based management training and development (MTD) in the SME sector in the United Kingdom. Survey data from (551) and interviews with (12) SMEs; plus interviews (6) with TECs and interviews (29) with providers of MTD are reported. ‘Product’ deficiencies in competence‐based MTD are identified and recommendations for promotion made.  相似文献

Using a two‐period model this paper examines the quantity decisions of leveraged duopolists that are vulnerable to bankruptcy in the first period. When the firms have symmetric costs, a bankrupt firm reorganizes under Chapter 11. If a Chapter 11 firm experiences marginal cost relief, each firm produces a collusive output in period one in order to prevent its rival's financial demise. When the firms have asymmetric costs, the less efficient firm is liquidated under Chapter 7 upon bankruptcy. A predatory equilibrium exists, whereby the inefficient firm is driven from the market.

This article identifies traces of the state in three urban neighborhoods of Mexico City. Instead of asking what is the state, where is it located or what does it do, the question posed here is: what are the effects of state practices at the street level? By ethnographically and visually describing how protection is performed, the article argues that the state is not only ‘somewhere’ in specific functions, actors or institutions; it also manifests materialized effects produced by a web of conflict‐ridden relations. Discussion about the state in the global South generally revolves around its failures and informality. The proposal here is that, by analyzing the state from the standpoint of urban space, the focus is on how protection is performed and by means of which operations, relations, objects and actors—not whether the state works or not, or whether actors are formal or informal. Based on ongoing ethnographic work and a collaboration with two visual artists in Mexico City, the article analyzes three protective processes: the ‘muscles’ (involving actors including police officers, gang leaders, fathers and husbands), the ‘saint’ (involving caring for representations of various saints and participation in other clientelistic chains of fidelity) and the ‘amparo’ (a form of application of the rule of law in a personalized manner for the redress of interpersonal conflicts). These are three sets of practices that have been embedded in Mexico's history of state formation since the days of colonization.  相似文献

The aim of this article is to analyze the extent to which organizational culture contributes to the symptoms of psychological distress in the workforce. Integrating organizational culture and work organization conditions makes it possible to examine how culture is associated with the various components of work organization conditions, and how these conditions might relate to symptoms of psychological distress in employees. Data from the SALVEO study were collected in 2009–2012 from a sample of 1824 individuals nested in 60 Canadian workplaces. Multilevel regression models were used to analyze the data. After controlling for individual and family characteristics, only group and rational cultures were associated with psychological distress, but both type of organization cultures were mediated by work organization conditions. Group culture is indirectly associated with lower levels of psychological distress since it favors lower levels of psychological demands and job insecurity. Rational culture is indirectly associated with higher levels of psychological distress because it favors higher psychological demand levels. The results obtained highlighted the importance of including variables relating to broader organizational context in models examining stress in the workplace.  相似文献

We introduce career success schemas as critical for understanding how people in different contexts perceive and understand career success. Using a comparative configurational approach, we show, in a study of 13 countries, that two structural characteristics of career success schemas—complexity and convergence—differ across country contexts and are embedded in specific configurations of institutional factors. Adopting complexity and convergence as primary dimensions, we propose a taxonomy of career success schemas at the country level. Based on this taxonomy, we contribute to the understanding of subjective career success across countries, discuss the importance of schemas for organisational career systems in multinational enterprises, and propose specific guidelines for future comparative careers research.  相似文献
