Many sampling problems from multiple populations can be considered under the semiparametric framework of the biased, or weighted, sampling model. Included under this framework is logistic regression under case–control sampling. For any model, atypical observations can greatly influence the maximum likelihood estimate of the parameters. Several robust alternatives have been proposed for the special case of logistic regression. However, some current techniques can exhibit poor behavior in many common situations. In this paper a new family of procedures are constructed to estimate the parameters in the semiparametric biased sampling model. The procedures incorporate a minimum distance approach, but are instead based on characteristic functions. The estimators can also be represented as the minimizers of quadratic forms in simple residuals, thus yielding straightforward computation. For the case of logistic regression, the resulting estimators are shown to be competitive with the existing robust approaches in terms of both robustness and efficiency, while maintaining affine equivariance. The approach is developed under the case–control sampling scheme, yet is shown to be applicable under prospective sampling logistic regression as well. 相似文献

Epidemic Models of the Onset of Social Activities (EMOSA) describe behaviors that spread through social networks. Two social influence methods are represented, social contagion (one-to-one spread) and general diffusion (spread through cultural channels). Past models explain problem behaviors—smoking, drinking, sexuality, and delinquency. We provide review, and a tutorial (including examples). Following, we present new EMOSA models explaining changes in adolescent and young adult religious participation. We fit the model to 10 years of data from the 1997 U.S. National Longitudinal Survey of Youth. Innovations include a three-stage bi-directional model, Bayesian Markov Chain Monte Carlo (MCMC) estimation, graphical innovations, and empirical validation. General diffusion dominated rapid reduction in church attendance during adolescence; both diffusion and social contagion explained church attendance stability in early adulthood. 相似文献

Current policies suggest that collaborative approaches are core to working effectively with juvenile justice involved young people. However, there is little research examining the workings of multi‐agency and collaborative endeavours in this field, or the experiences of the human service workers facilitating these connections. This paper reports on qualitative research that resulted from the Juvenile Justice and Education Equity in the Hunter Region project. Thirty‐eight human service workers were interviewed about their perceptions of the workings, strengths and challenges of the service system that supports young people who come into contact with the Children's Court in the Lower and Upper Hunter regions of New South Wales. Data analysis revealed three key themes related to (1) service gaps, cycles and maelstrom; (2) pursuing authentic service engagement; and (3) insider–outsider dynamics in service provision. Findings are discussed in relation to emerging practice and research agendas. 相似文献

People with HIV infection are subjected to prejudice, discrimination and hostility related to the stigmatization of AIDS. To manage the stigma of their disease, they mount complex coping strategies. This paper reports results from a qualitative study that examined gay/bisexual men's experiences of living with HIV infection. Unstructured interviews from a diverse sample of 139 men were analyzed to examine how men coped with AIDS-related stigma. We discerned a variety of stigma management strategies that could be arranged along a continuum from reactive to proactive based on the extent to which they implicitly accepted or challenged the social norms and values that underlie the stigmatization of HIV/AIDS. Reactive strategies to cope with stigma involve defensive attempts to avoid or mitigate the impact of stigma, but imply acceptance of the underlying social norms and values that construct the stigma. Examples of reactive strategies include hiding one's HIV status, presenting one's illness as a less stigmatizing one (e.g., cancer), or distancing one's self from more damaging aspects of AIDS-stigma (e.g., attributing infection to blood transfusion). Proactive strategies challenge the validity of the stigma and imply disavowal and resistance of the social norms and values that underlie the stigma. Examples of proactive strategies include engaging in public educational efforts that address misperceptions about HIV transmission and social activism to change the social and political conditions that affect PWA/HIV. 相似文献

Objectives . Although scholars have recognized that the wealth and power of litigants has substantial influence on litigation outcomes, there has been less recognition of the ability of the wealthy to sway agency policy through litigation. I argue that the wealthy, through lawsuits and the outcomes from the litigation, influence Internal Revenue Service (IRS) audits of the wealthy and the less affluent. Methods . I examine IRS state audit rates and use ordinary least squares regression with panel corrected standard errors. Results . I show that wealthy litigants can influence the IRS to decrease audits of the wealthy and increase audits of the less affluent. Conclusions . The wealthy appear to have the ability to influence IRS policy through lawsuits. Litigation can influence agency policy. 相似文献
