Compte tenu de l'importance des activités informelles, l'auteur propose de classer les pays selon les dimensions de l'emploi dans l'économie informelle plutôt que selon la composition de l'économie formelle. A partir de données du BIT portant sur trente‐six pays en développement, il fait apparaître une corrélation significative entre l'étendue et l'intensité de l'informalité et différents indicateurs sociaux et économiques: PNB par habitant, degré de corruption et de pauvreté et niveau de l'impôt et des cotisations sociales. Les implications de ces résultats pour la réflexion théorique et l'action sont ensuite exposées. 相似文献

The influence of risk perceptions on risk activities of teenagers is well known, but the development of indices, which combine measures of perception as well as behavioral outcomes, has proved problematical. This article discusses the ways in which this methodological problem was tackled within a five-year, multiphase, multimethod study of factors affecting adolescent risk-taking in Tasmania, Australia, which included an intergenerational comparison of adolescents and parents. The development of the Risk Activity by Personal Risk Assessment (RAPRA) Index combines measures of perceived riskiness of 26 activities identified by young people as involving varying degrees of risk, with the degree of participation by each respondent, through a rectangular model of weights. The Personal Risk Score Category (PRISC) Index summarizes and categorizes an individual's risk-taking profile relative to the group's risk values and risk hierarchy established by the RAPRA Index. The article discusses ways in which technical problems involved in combining measures of risk perceptions and risk activities were addressed during index construction, compared with examples in the literature. Some key findings from analysis of two student and parent samples are presented as exemplars of the methods used and the results produced. Findings demonstrate the widespread nature of risk-taking among teenagers, and the similarity of levels of risk-taking between teenager and parental generations. The indices allow for detailed comparison of particular risk-taking activities and reveal differences among teenagers now compared with parents when they were teenagers, and illustrate the dynamic cultural context of risk-taking perceptions and values. 相似文献

This paper re-examines the debate about the class rationality of the working-class demand for a family wage and argues that this issue cannot be resolved without considering the feasibility of alternative strategies. Existing accounts are criticized for their unrealistic treatment of these alternatives and the constraints upon them and particularly for their neglect of the influence of the policies of employers and the state upon working-class strategies. The argument is supported by discussion of the economic and political context of the family wage demand in Britain up to the First World War and concludes that the strategy was more rational than many writers have suggested. 相似文献

Current systems for investigating child deaths in England, Wales and Northern Ireland have come under intense scrutiny in recent years and questions have been raised about the accuracy of child death investigations and resulting statistics. Research has highlighted the ways in which multidisciplinary input can contribute to investigative and review processes, a perspective which is further supported by recent UK policy developments. The experience of creating multidisciplinary child death review teams (CDRTs) in America highlights the potential benefits the introduction of a similar system might have. These benefits include improved multi‐agency working and communication, more effective identification of suspicious cases, a decrease in inadequate death certification and a broader and more in‐depth understanding of the causes of child deaths through the systematic collection and analysis of data. While a lack of funding, regional coordination and evaluation limit the impact of American CDRTs, the positive aspects of this process make it worthwhile, and timely, to consider how such a model might fit within our own context. Current policy developments such as the Home Office review of coroner services, the Children Bill and related Department for Education and Skills (DfES) work on developing screening groups demonstrate that strides have been made in respect of introducing a multidisciplinary process. Similarly, the development of local protocols for the investigation and[sol ]or review of child deaths in England, Wales and Northern Ireland highlights an increased focus on multidisciplinary processes. However, key issues from the American experience, such as the remit of CDRTs[sol ]screening panels, the need for national coordination and the importance of rigorous evaluation, can inform the development of a similar process in the UK.

In this article, we consider a model for an airport security system in which the declaration of a threat is based on the joint responses of inspection devices. This is in contrast to the typical system in which each check station independently declares a passenger as having a threat or not having a threat. In our framework the declaration of threat/no-threat is based upon the passenger scores at the check stations he/she goes through. To do this we use concepts from classification theory in the field of multivariate statistics analysis and focus on the main objective of minimizing the expected cost of misclassification. The corresponding correct classification and misclassification probabilities can be obtained by using a simulation-based method. After computing the overall false alarm and false clear probabilities, we compare our joint response system with two other independently operated systems. A model that groups passengers in a manner that minimizes the false alarm probability while maintaining the false clear probability within specifications set by a security authority is considered. We also analyze the staffing needs at each check station for such an inspection scheme. An illustrative example is provided along with sensitivity analysis on key model parameters. A discussion is provided on some implementation issues, on the various assumptions made in the analysis, and on potential drawbacks of the approach. 相似文献

Pressures towards and against formalization: Regulation and informal employment in Mozambique 下载免费PDF全文
Pauline DIBBEN Geoffrey WOOD Colin C. WILLIAMS 《International labour review / International Labour Office》2015,154(3):373-392
The informal economy accounts for the bulk of employment in many emerging economies. Regulation theory suggests that all economic activity is characterized by a complex combination of formal and informal regulation. Looking at the case of Mozambique, this article explores the pressures towards and against formalization, and the forms regulation can take, drawing on qualitative research based on in‐depth elite interviews and observation. The findings highlight how the State's role in promoting formalization of the informal economy is ambivalent; its approach incorporates both “progressive” elements, which focus on the modernization of regulations and institutions, and “conservative” elements, which inhibit this process of change. 相似文献
