Theorists of social movements have not developed a sufficiently complex perspective of the role that ideology has in the dynamics of social movements. This essay demonstrates that Habermas’theory of the autonomy of normative structures is useful to explain the independent role of ideology in determining the direction taken by social movements. Habermas’emphasis on the interrelationship between cultural traditions, consensus formation, epistemologies, and differentiated rationalization processes furnishes an alternative to the instrumentalist and ahistorical assumptions that often characterize theorists’treatment of ideology in social movements. Empirical examples from studies of social movements are utilized to demonstrate the usefulness of Habermas’approach. 相似文献

In light of the Armitage-Doll multistage carcinogenesis theory, this paper examines the assumption that an additive relative risk relationship is indicative of two carcinogens that affect the same stage in the cancer process. We present formulas to compute excess cancer risks for a variety of patterns for limited exposure durations to two carcinogens that affect the first and penultimate stages; and using an index of synergy proposed by Thomas (1982), we find a number of these patterns to produce additive, or nearly additive, relative risk relationships. The consistent feature of these patterns is that the two exposure periods are of short duration and occur close together. 相似文献

We consider statistical inference on parameters of a distribution when only pooled data are observed. A moment-based estimating equation approach is proposed to deal with situations where likelihood functions based on pooled data are difficult to work with. We outline the method to obtain estimates and test statistics of the parameters of interest in the general setting. We demonstrate the approach on the family of distributions generated by the Box-Cox transformation model, and, in the process, construct tests for goodness of fit based on the pooled data. 相似文献

Exact testing in multivariate regression 总被引:1,自引:0,他引:1

An F statistic due to Rao (1951,1973) tests uniform mixed linear restrictions in the multivariateregression model. In combination with a generalization of the Bera-Evans-Savin exact functional relationship between the W, LR, and LM statistics, Rao's F serves to unify a number of exact test procedures commonly applied in disparate empirical literatures. Examples in demand analysis and asset pricing are provided. The availability of exact tests of restrictions in certain nonlinear models when the model is linear under the null, originally explored by Milliken-Graybill (1970), is extended to multivariate regression. Generalized RESET, J-, and Hausman-Wu tests are resented. As an extension of Dufour (1989), bounds tests exist for nonlinear and inequality restrictions. Applications include conservative bound tests for symmetry or negativity of the substitution matrix in demand systems. 相似文献

This article examines second-generation Asian Americans' explanations of the significant influences on their own religious identities. Data include interviews (N = 73) with college-aged Asian Americans from different religious traditions and ethnic backgrounds. Respondents viewed families as the most significant influence on current religiosity. Mothers and fathers were mentioned most often, followed by extended kin, siblings, and relatives, who acted as what we call "reinforcers,""substitutes," or "contrasts" to the roles that parents played in religious socialization. These roles occurred along two religious configurations within families: heterogeneous or homogeneous degrees of religious commitment and religious affiliation. Directions for future research and contributions to the religious transmission literature follow. 相似文献

The National Disability Insurance Scheme (NDIS) is one of the most significant initiatives in Australian social policy history. Its complexity has been compounded by a fast-paced introduction and ongoing refinement throughout the initial trial phase. Parents and carers of very young disabled children face particular challenges accessing and navigating NDIS systems. This article presents findings from a mixed-method pilot study examining the perspectives of parents and carers of disabled children in one NDIS trial site – the Hunter Region of New South Wales. The research highlights a number of policy assumptions potentially impacting on NDIS take up for young disabled children and their families in regional contexts. Based on research findings a number of policy suggestions and improvements for disabled children and their families entering the NDIS and other individualised funding schemes are outlined. 相似文献

This article examines the relationship between personal discount rates and sexual behaviors in a sample of teenagers and young
adults. We find that higher discount rates (an indication of less willingness to forego current consumption for future consumption)
are significantly associated with a range of sexual behaviors, including ever having sex, having sex before age 16 years,
and past or current pregnancy. These associations are consistent with previous studies showing a link between discounting
and other, non-sexual health behaviors.

Governmental and private sector social services organizations have traditionally shared important roles for provision and delivery of social services in the United States. Over the past fifty years, however, a predominant position has developed for the public sector, especially through federal funding for social service programmes. Recent challenges to the prevailing role of public sector dominance have been expressed by the proponents for privatization at a time when decreasing federal funds are made available for social service programmes. The analysis presented here examines the potential and problems associated with the privatization strategies offered through load shedding, limited-government arrangements, fee charging and competition. As a macro level approach for a comprehensive system of social service provision and delivery, these privatization strategies raise more questions than immediate solutions. A more optimistic view is taken if privatization leads to a more meaningful balance with increased co-operation between public and private social welfare auspices. 相似文献
