High Fertility in City Suburbs: Compositional or Contextual Effects?

Fertility rates are known to be higher in city suburbs. One interpretation is that the suburban ‘context’ influences the behaviour of individuals who reside there while an alternative is that the ‘composition’ of the suburban population explains the higher fertility levels. Furthermore, suburban in-migrants who intend to have children may have a significant influence on suburban fertility rates. Using Finnish longitudinal register data we show that fertility rates are higher in the suburbs and rural areas and lower in the cities. Fertility variation across these residential contexts decreases significantly after controlling for women’s demographic and socio-economic characteristics. However, it does not disappear entirely suggesting that the local context may have some influence on fertility. While movers to suburbs do display higher fertility levels than non-migrant residents, their overall impact is not great because they form a small share of the suburban population.     

Peer 2 Peer: Efficacy of a Course-Based Peer Education Intervention to Increase Physical Activity Among College Students

Abstract

There are few physical activity (PA) interventions in higher education, and they have been only minimally effective. Objective: To determine if a course-based, peer education intervention was associated with increases in PA and physical fitness. Participants: Participants were 178 students enrolled in a personal health class during the 2007–2008 academic year. Methods: A quasi-experimental design was used to assess the effect of the intervention. Repeated measures analysis of covariance was employed to test the impact of the intervention on students’ PA, body composition, waist-to-hip ratio, cardiovascular fitness, flexibility, and muscular strength. Results: Women in the treatment group classified as “Inactive” at baseline increased PA, whereas “Inactive” control women had reductions in PA. Women in the treatment group who were “Active” at baseline reduced their waist-to-hip ratio and increased flexibility. There were no differences by treatment group among men. Conclusions: The intervention was effective in improving PA and physical fitness among college women.     

Maximum likelihood methods for complex sample data: logistic regression and discrete proportional hazards models

To estimate model parameters from complex sample data. we apply maximum likelihood techniques to the complex sample data from the finite population, which is treated as a sample from an i nfinite superpopulation. General asymptotic distribution theory is developed and then applied to both logistic regression and discrete proportional hazards models. Data from the Lipid Research Clinics Program areused to illustrate each model, demonstrating the effects on inference of neglecting the sampling design during parameter estimation. These empirical results also shed light on the issue of model-based vs. design-based inferences.     

On nonlinear random effects models for repeated measurements

Linear random effects models for longitudinal data discussed by Laird and Ware (1982), Jennrich and Schluchter (1986), Lange and Laird (1989), and others are extended in a straight forward manner to nonlinear random effects models. This results in a simple computational approach which accommodates patterned covariance matrices and data insufficient for fitting each subject separately. The technique is demonstrated with an interesting medical data set, and a short, simple SAS PROC IML program based on the EM algorithm is presented.     

Autonomy in long‐term care: a need,a right or a luxury?

Doyal and Gough’s theory of human need highlighted that personal autonomy is a universal need and human right, essential for well‐being. In applying their theory to older disabled people in the UK the author suggests that their ‘minimally autonomous’ threshold would exclude some older people in long‐term care who still have a fundamental need for autonomy or, alternatively, extant autonomy. The disability movement has highlighted that independent living is fundamental to achieving self‐determination for disabled people and debate on equality and caregiving emphasises the autonomy of carers. However, there is a lack of recognition in both academic research and government policy of autonomy as a need and right of older disabled people. The author argues that autonomy is a human right of older people living in long‐term care settings, but that social rights are necessary to facilitate their autonomy.

Lesbian, gay, and bisexual homeless youth: an eight-city public health perspective

This article reports on results of a one-day public health survey conducted in six states by homeless youth providers to measure and compare risk factors between lesbian, gay, and bisexual (LGB) homeless youth and non-LGB homeless youth. This article intends to inform the child welfare field on existing gaps in services and areas where more training and technical support is necessary in providing services to homeless LGB youth. The findings point to substantial differences within the homeless youth sample and demonstrate that in addition to the public health risks young people face merely by being homeless, the risks are exacerbated for those who self-identify as lesbian, gay, or bisexual. The article informs child welfare providers and policymakers about the substantial vulnerability of LGB youth beyond that of non-LGB homeless youth and the need to fund programming, training, technical assistance and further research to specifically respond to the complex needs of this population.     

Critical Realism and the Althusserian Legacy

This paper undertakes an historical re‐evaluation of Louis Althusser's philosophical legacy for modern Marxism. While Althusser self‐consciously sought to defend the scientific character of Marxism, many of his closest followers eventually exited the Marxian paradigm for a post‐structural post‐Marxism. We argue that this development was predominately rooted in a series of philosophical errors that proved fatal in a period of retreat for European socialism. There has always been, however, a second post‐Althusserian legacy associated with the critical realist conception of Marxism initiated by Roy Bhaskar. Bhaskar found part of his inspiration in Althusser's successful posing of the question of Marx's science and this paper sets out to excavate the proper links between Althusser and Bhaskar in order to deepen the relationship between critical realism and scientific Marxism.
