This article applies a labor process analysis to the issue of employment rights in the particular context of gender inequality
and unlawful discrimination in the recruitment process. It criticizes conventional perspectives on employee rights for their
failure to examine critically managerial power and prerogative and its implications for gender inequality. The article outlines
two particular labor process theories of gender divisions and inequality. In exploring the strengths and weaknesses of these
more critical perspectives, the article highlights the analytical significance that they ascribe to power asymmetries in the
labor process and labor market. Building on this perspective, the analysis then presents empirical data on gender discrimination
in the selection practices of contemporary UK organizations. The research material reveals how gender discrimination can be
reproduced, rationalized, and resisted. These empirical findings are theorized through a combined labor process analysis of
power, knowledge, and identity in recruitment practices. We conclude that labor process analysis facilitates our understanding
of the deep-seated barriers that continue to impede the protection of employee rights in workplace practices. 相似文献

西安市泔水油循环利用模式研究 总被引:1,自引:0,他引:1
伴随我国餐饮业的高速增长,泔水油问题日益严重。但是目前论述泔水油问题的文章还很少,涉及泔水油循环利用的更少。本文分析了西安市泔水油利用现状,包括泔水油的总量、流向、清运、处置方式、各渠道的流量比例及西安市治理泔水油的政策历程。在此基础上,借鉴国内外的经验,提出了西安市泔水油循环利用的新模式,以及在这种新模式下泔水油循环利用的基本原则、政府的角色等。 相似文献

风险投资家的最优激励契约模型研究--一种基于逆向选择和道德风险条件下的博弈模型分析 总被引:4,自引:0,他引:4
为减少风险投资融资中风险投资家的逆向选择和道德风险,风险投资者必须设立一套有效的激励机制来让风险投资家选择,从而根据风险投资家选择的结果来甄别其真实能力类型,同时又能激励其努力工作。文章建立了风险投资家能力类型和努力都是不可观测条件下的最优激励契约模型,并根据显示原理,利用最优控制理论求出了最优解进而进行了分析。得出的结论是:最优激励契约能使高能力风险投资家乐于选择具有高强度激励、低固定收入和风险小的项目,同时又能激励其签约后更加努力工作。 相似文献

A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services. 相似文献

This paper analyses the political support for a social insurance that includes elements of redistribution when there exists an imperfect private insurance alternative. Individuals differ both in their income and risk. The social insurance is compulsory and charges an income-related contribution with pooling of risks. The private insurance is voluntary and charges a contribution based on individual risks. However due to the adverse selection problem, private insurance companies provide only partial insurance. Adopting a non-expected utility model, we show that there is a general majority support for social insurance and that this support is increasing with risk aversion. We also show that a mixed insurance is politically impossible, regardless of the degree of redistribution of social insurance and the joint distribution of risk and income in the population. Lastly, we analyse how the political support for social insurance is affected by any change in its redistributive component and the possibility of using genetic tests. 相似文献

This paper uses the experimental method to investigate behavior in a coordination game when the information available to subjects
is limited to their feasible choices and their experienced payoffs. In the experiment subjects converge to an absorbing state
at rates that are orders of magnitude faster than reinforcement learning algorithms, but slower than under complete information.
This state is very close to a mutual best response outcome. All cohorts converged to the market statistic predicted by the
interior equilibrium regardless of the information conditions or the stability conditions.
