Under the influence of the "new history of the family" of the past few decades, a revisionist view of the "modern family" has emerged among family theorists in Japan. In spite of the significant merits of this new paradigm, I have argued that the failure of its proponents to address certain theoretical and presuppositional issues has discouraged a cultural analysis of the modern family. In recent years, one of the foremost theorists to attempt to bring cultural analysis fully into sociological discourse has been Jeffrey Alexander. I have drawn extensively on Alexander's discussion of Durkheim's later thought as the key to a cultural program in the field of sociology. In doing so, I have suggested that one effect of the transition to modern society is the sacralization of what Durkheim termed the "domestic order". Furthermore, in considering the mechanism by which the central emotional axis of the family comes to revolve around either the parent–child bond or the conjugal bond, I have postulated the existence of a "sacred" dyad—in the Durkheimian sense—within the family unit. 相似文献

笔者通过对东北老工业城市--长春市失业人员进行实地调查,运用均值分析、因子分析等方法,对失业者再就业行为的差异进行辨别,发现对有再就业意愿的失业者而言,搜寻工作的思想观念与方式、失业期间的活动能力、失业者的心态、当地公共就业服务质量都是导致失业者再就业行为产生差异的主要因素.由此笔者分析了影响失业者再就业行为的内在机制,探讨激励失业者积极再就业的措施,以期为完善我国公共就业服务体系提供政策建议. 相似文献

<史记>叙事首创"互见法",取得了很高的艺术成就.然而,今人在嘉许<史记>"互见法"首创价值的时候,对部分互见文字的真伪要谨慎,还应看到<史记>"互见法"体系并不完备,<史记>"互见法"的运用还不很自觉,特别是"互见法"对于今人还原<史记>"一家之言"的哲学真相有很大的干扰. 相似文献

The primary purpose of this study is to typify the respondent strategies of the OECD countries based on the interconnected structure of income and employment guarantees. More specifically, this article seeks to typify welfare policies into four types (welfare-to-work, welfare emphasis, labour emphasis, market emphasis) based on the leniency of the pension system and active state intervention in employment security. With the resultant four types, this article then places them as the dependent variable while incorporating per capita GDP, aged dependency ratio, pension maturity level, union density, constitutional structure index and degree of decommodification as causal variables. Through this process, this article aims to derive the decisive variable for each type through qualitative comparative analysis. 相似文献

While the concept of regular equivalence is equally applicable to dichotomous as well as valued networks, the identification of regular blocks in regular blockmodels is somewhat problematic when dealing with valued networks. Applying the standard procedure for identifying ties in such blockmodels, a procedure perhaps most suited for dichotomous networks, does tend to generate block images and reduced graphs that differ from intuitive notions of such structures. 相似文献

In relation to mental health, it is clear that medicalized underpinnings,the provision of a clinically orientated evidence base for practiceand the need to contain risk continue to be prioritized,particularly when compulsory intervention is considered. Thisis despite the increasing influence of a citizenship and socialjustice agenda which is being promoted by psychiatrists involvedin the development of postpsychiatry, as wellas by service users/survivors. These drivers are not mutuallyexclusive, but in the context of compulsory treatment, thereare clear tensions. In this article, the policy surroundingmental health and compulsory intervention in Australia and inEngland and Wales is explored. In the context of this discussion,three ways in which current government policy can be interpretedare examined and links made between these interpretations anddifferent ways of viewing the relationship between mental healthand community capacity building. With regard to social workpractice, it is argued that a response to mental ill healthwhich concentrates on an individualized diagnose andtreat approach, which particularly comes to the foreat times of compulsory intervention, has limited capacity tofacilitate community engagement, foster social inclusion andgenerate reciprocal dynamics between positive mental healthand community capacity building. 相似文献
