The ℓ1 oblique procrustes problem

In this paper, we reconsider the well-known oblique Procrustes problem where the usual least-squares objective function is replaced by a more robust discrepancy measure, based on the ₁ norm or smooth approximations of it.We propose two approaches to the solution of this problem. One approach is based on convex analysis and uses the structure of the problem to permit a solution to the ₁ norm problem. An alternative approach is to smooth the problem by working with smooth approximations to the ₁ norm, and this leads to a solution process based on the solution of ordinary differential equations on manifolds. The general weighted Procrustes problem (both orthogonal and oblique) can also be solved by the latter approach. Numerical examples to illustrate the algorithms which have been developed are reported and analyzed.     

An attribution model of public discrimination towards persons with mental illness

In this study, we build on previous work by developing and estimating a model of the relationships between causal attributions (e.g., controllability, responsibility), familiarity with mental illness, dangerousness, emotional responses (e.g., pity, anger, fear), and helping and rejecting responses. Using survey data containing responses to hypothetical vignettes, we examine these relationships in a sample of 518 community college students. Consistent with attribution theory, causal attributions affect beliefs about persons' responsibility for causing their condition, beliefs which in turn lead to affective reactions, resulting in rejecting responses such as avoidance, coercion, segregation, and withholding help. However, consistent with a danger appraisal hypothesis, the effects of perceptions of dangerousness on helping and rejecting responses are unmediated by responsibility beliefs. Much of the dangerousness effects operate by increasing fear, a particularly strong predictor of support for coercive treatment. The results from this study also suggest that familiarity with mental illness reduces discriminatory responses.     

The incorporation of gender scholarship into sociology

The prospects of an intellectual revolution in sociology informed in part by a feminist perspective loomed large in the early 1970s. Following Ward and Grant's (1985) empirical examination of gender and feminist scholarship in sociology journals between 1974 and 1983, our research provides an empirical assessment of the “second ten years” after the feminist critique of the discipline, 1984–1993. Specifically, we examine the incorporation of gender-content scholarship into mainstream sociology journals. Our research also assesses the extent to which gender-content scholarship published in these journals is feminist-oriented or not and the extent to which this is influenced by the sex of authors, the type of journal, and the sex composition of editorships and editorial boards. Our findings indicate that although there were more gender- and feminist-oriented articles published in the recent ten-year period, proportionally there were fewer feminist-oriented articles than in the previous ten-year period. Our findings suggest that a feminist revolution in sociology is not likely to occur anytime soon, although the assimilation of feminist scholarship into sociology is occurring along the lines of other critical intellectual movements in recent decades.

Power of the First Hour

Abstract

In 2012, the NGO Save the Children launched its No Child Born to Die campaign with the tagline, “Breastfeeding Saves Lives.” The press release explains that in the first hours and days after a baby is born, their mother produces colostrum, a substance known to improve immunity, which must be delivered to infants in the first sixty minutes of life; this is referred to as “the power of the first hour.” Invoking a sense of urgency and a crisis of infant mortality, which breastfeeding is positioned to resolve, the campaign cites staggering medical statistics of infant deaths in the campaign targets of Africa, Asia and Latin America, and also Northern Indigenous and Inuit reserves in Canada. More than misrepresenting racialized women in the developed world as uneducated on infant health, childcare and child rearing and as lacking agency and empowerment, the campaign mobilizes the erroneous conflation of medical science, morality, capitalism and public health – a linkage typically mobilized by the development industry to the detriment of globally marginalized women. In order to understand how this conflation is mobilized to manufacture crisis at the expense of examining the root causes of infant mortality globally, we collect theories of crisis temporalities to develop a “feminist politics of crisis.”     

Diesel Engine Exhaust and Lung Cancer Mortality: Time‐Related Factors in Exposure and Risk

To develop a quantitative exposure‐response relationship between concentrations and durations of inhaled diesel engine exhaust (DEE) and increases in lung cancer risks, we examined the role of temporal factors in modifying the estimated effects of exposure to DEE on lung cancer mortality and characterized risk by mine type in the Diesel Exhaust in Miners Study (DEMS) cohort, which followed 12,315 workers through December 1997. We analyzed the data using parametric functions based on concepts of multistage carcinogenesis to directly estimate the hazard functions associated with estimated exposure to a surrogate marker of DEE, respirable elemental carbon (REC). The REC‐associated risk of lung cancer mortality in DEMS is driven by increased risk in only one of four mine types (limestone), with statistically significant heterogeneity by mine type and no significant exposure‐response relationship after removal of the limestone mine workers. Temporal factors, such as duration of exposure, play an important role in determining the risk of lung cancer mortality following exposure to REC, and the relative risk declines after exposure to REC stops. There is evidence of effect modification of risk by attained age. The modifying impact of temporal factors and effect modification by age should be addressed in any quantitative risk assessment (QRA) of DEE. Until there is a better understanding of why the risk appears to be confined to a single mine type, data from DEMS cannot reliably be used for QRA.     

‘The Bad People Go and Speak to Her’: Young People’s Choice and Agency when Accessing Mental Health Support in School

Concerns about the mental health and well‐being of children and young people have been articulated in health and education policy fields as a call for closer working between schools and providers of mental health support services. Drawing from a Scottish study, this article explores issues of access, when mental health initiatives are sited in formal educational settings. In particular, it focuses on the implications for the agency of children and young people seeking support from those services when and how they choose. The study argues that over‐reliance on teachers as the main referral route to service influences what is deemed to be a problem, who is thought to need support and how the interventions are viewed by the children and young people. Alternative approaches are discussed, which offer opportunities for children and young people to explore the available services and make their own choices about their level of engagement.
