A characteristic function approach to the biased sampling model,with application to robust logistic regression

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.     

NEGOTIATING CONTINUITY: Family and Religious Socialization for Second-Generation Asian Americans

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.     

‘I’m not really sure but I hope it’s better’: early thoughts of parents and carers in a regional trial site for the Australian National Disability Insurance Scheme

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.     

Teaching social research methods after the critical turn: challenges and benefits of a constructivist pedagogy

An increasing challenge for teaching methods courses in the social sciences is the ‘critical turn’, which has encouraged some students to adopt an anti-empirical orientation. We present a case study of a compulsory undergraduate methods course in a political science department strongly influenced by post-structuralist philosophies. The first author redesigned the course to implement four constructivist pedagogical principles: (1) develop a full understanding of students’ pre-existing perceptions of political science research methods; (2) encourage students to see methodology as an inevitably contested field; (3) provide space for students to choose a methodological approach that best aligns with their personal stance on knowledge; and (4) encourage students to view research as an ongoing ‘conversation’. We critically reflect on the implementation of these constructivist pedagogical strategies and argue they improve students’ critical engagement with course material, increase linkages between methods teaching and other disciplinary subject matter, and accommodate diverse student perspectives and needs.     

Estimating the prevalence of adolescent gambling disorders: A quantitative synthesis and guide toward standard gambling nomenclature

This article reviews the extant published and unpublished studies that estimate the prevalence of adolescent gambling problems in North America. The nine nonduplicative studies identified by our literature search included data collected from more than 7700 adolescents from five different regions of the United States and Canada. In addition to comparing the conceptual and methodological differences that exist among these studies, this article employed a meta-analytic strategy to synthesize prevalence estimates from the existing studies. This analysis revealed that within a 95 percent confidence interval, between 9.9% and 14.2% of adolescents are at risk of developing or returning to serious gambling problems. Similarly, between 4.4% and 7.4% of adolescents exhibit seriously adverse compulsive or pathological patterns of gambling activity. Finally, the discussion proposes a generic multi-level classification scheme to reconcile the divergent classification methods and data reporting strategies. This new multi-level approach to reporting gambling prevalence will facilitate interstudy comparisons among existing estimates of gambling prevalence and help to provide a general data reporting system for future research.     

Discount rates and risky sexual behaviors among teenagers and young adults

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. JEL Classification D80 · D90 · I10     

Privatizing Social Services in the U.S.A.

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.     

Adolescent Religiosity and School Contexts*

Objectives. Schools serve as the primary social organizations for adolescents, structuring their lives and conveying a variety of skills, norms, and values, but relatively little is known about how schools influence the development of religious belief, attitudes, and behavior during adolescence. We explore how schools' religious norms, coupled with adolescents' pursuit of social status through conformity, affect public and private religiosity. Methods. Employing data from the National Longitudinal Study of Adolescent Health (Add Health), we use multilevel modeling to examine the impact of school context on adolescents' public and private religiosity. Results. We find that school norms are influential in shaping both public religious expressions and private devotional activities, but pursuit of social status is a motivation for change across religious contexts only of public religious activity. The effect of social status as a motivator of religious change was moderated by the strength of the adolescent's identification with the school, especially for private religiosity. Conclusions. Schools play a key role in the social development of adolescents, and students' religious beliefs and behaviors are influenced systematically and observably by the type of religious climate within the school.     

Updating the Debate on Intergenerational Fairness in Pension Reform

This article examines the arguments involved in claims about the fairness or unfairness of government policies that would require current working generations to bear the full impact of their lower fertility on the costs of retirement pensions. The analysis is set in the context of a wider review of debate on the role of the idea of generational fairness in assessing options for reform under conditions of population ageing. The article considers three questions: whether generational fairness poses a serious problem for pay‐as‐you‐go pension schemes; whether it is reasonable to assess the generational fairness of pension policy in isolation from other kinds of generational transfer; and whether there is a good case for redistribution from future generations in favour of the baby boom generation.
