本文延承布迪厄的学术遗产,通过对茶村大龄未婚男青年进行分析后指出,家庭不仅构成了婚姻生活的重要场域,同时亦对婚姻本身产生了重要影响:当婚姻由家族事件变成家庭事件时,它由一个“公共事件”转变成“私密事件”,他人对于族人婚姻的关注与贡献也急剧降低;“家风”作为婚姻市场上的道德要价,对婚姻双方的社区道德和口碑提出了要求;当男青年的家庭结构不完整或经济实力不济,这将使得男性在婚姻市场上无法获得女方的青睐。  相似文献

Single index models are frequently used in econometrics and biometrics. Logit and Probit models arc special cases with fixed link functions. In this paper we consider a bootstrap specification test that detects nonparametric deviations of the link function. The bootstrap is used with the aim to rind a more accurate distribution under the null than the normal approximation. We prove that the statistic and its bootstrapped version have the same asymptotic distribution. In a simulation study we show that the bootstrap is able to capture the negative bias and the skewness of the test statistic. It yields better approximations to the true critical values and consequently it has a more accurate level than the normal approximation.  相似文献

This paper tries to establish a framework for sampling inspections by attributes based on soft quality standards to pay more attention to some shortcomings in classical modelling concerning the acceptability of inspection lots. As a suggestion, such sampling inspections are described in terms of a statistical test with fuzzy hypothesis and fuzzy data, extending the classical framework of sampling inspections by attributes. Furthermore, the operating characteristics will be explored, and single sampling plans of given strength are investigated.  相似文献

This study of UK and US lone parents with sole care-giving responsibility for dependants (children, ageing parents, grandparents, etc.) focused on the influence, if any, this responsibility has on her/his ability to give 'total commitment' to their work/career. One hundred and thirty-four lone parents participated in the survey. Gender distribution was 64 per cent female, 36 per cent male. Country of residence was 25 per cent UK, 75 per cent US. Females report greater past than present hindrance to their careers (48 per cent past, 33 per cent present). Similarly situated males report career hindrance as 18 per cent past, 21 per cent present. Lone parents in the UK appear to be more negatively impacted upon in their job careers by their care-giving responsibility than their counterparts in the US and would also appear to be more concerned about their economic and emotional future. This survey confirms that care-giving responsibilities can limit the realization of employment potential for either female or male. Care-giving responsibilities, rather than gender or race, may be the glass ceiling of the new millennium.  相似文献

With the emergence of activation policies, researchers are intrigued by the extent to which welfare‐to‐work (WTW) programmes reflect the ideological orientation of policymakers, while leaving the ideological orientation of their operators unexamined. This aspect may be of particular importance when women's non‐governmental organizations operate non‐coercive WTW programmes. Directing attention to the contribution of the operator, we ask how women who operate these programmes distinguish between the feminist goal of increasing women's independent access to material resources, and the activation rhetoric of ‘work first’. Moreover, as not enough is known about how participants benefit from the incongruence between the feminist discourse and the activation one, scholarship contemplating women's resistance to WTW programmes remains focused on specific welfare histories, and this form of feminist work remains neglected. The importance of the specific operators and the policy implications of the benefits of feminist operation of WTW programmes receive attention in the study reported on herein. We used a non‐coercive activation programme operated by a feminist organization in Israel (among other operators) as an opportunity to deepen our understanding of how programme trainers voice their position between feminism and activation discourse, and how their form of speech enables participants to insist on decent employment as a policy issue. Implications for policy are discussed.  相似文献

In this paper, we present closed-form expressions, wherever possible, or devise algorithms otherwise, to determine the expectation and variance of a given schedule on a single machine. We consider a variety of completion time and due date-based objectives. The randomness in the scheduling process is due to variable processing times with known means and variances of jobs and, in some cases, a known underlying processing time distribution. The results that we present in this paper can enable evaluation of a schedule in terms of both the expectation and variance of a performance measure considered, and thereby, aid in obtaining a stable schedule. Additionally, the expressions and algorithms that are presented, can be incorporated in existing scheduling algorithms in order to determine expectation-variance efficient schedules.  相似文献

在外语教学中一直有人提倡采用直接教学法,创造完全的外语环境,消除汉语的影响,强制学生用外语思维.一些从事外语教学的教师也试图通过单语教学引导学生用外语思维,但是长期的实践结果证明,这种教学方法效果并不理想,在国外也渐渐地不受推崇.笔者通过问卷调查发现日语专业的学生在学习日语过程中,大多依靠母语思维,对于零起点的日语专业学生来说,完全使用日语教学的方法是不现实的,也是不科学的.母语思维在日语专业教学中起着重要的作用.  相似文献

本文从博弈论的角度研究了单一制造商和多个零售商之间的合作与非合作博弈问题。研究结果表明:制造商和零售商之间的知识共享机制具有内在不稳定性;制造商和零售商都会陷入"囚徒困境",而制造商的成本补贴激励政策无法解决该问题。在上述分析的基础上,本文提出通过合理控制供应链中参与知识共享企业的数量,建立共享平台,培育共享文化等策略提高制造商与零售商知识共享。  相似文献
