Bayesian Inference in Multivariate Regression With Missing Observations on the Response Variables

We discuss the case of the multivariate linear model Y = XB + E with Y an (n × p) matrix, and so on, when there are missing observations in the Y matrix in a so-called nested pattern. We propose an analysis that arises by incorporating the predictive density of the missing observations in determining the posterior distribution of B, and its mean and variance matrix. This involves us with matric-T variables. The resulting analysis is illustrated with some Canadian economic data.     

Beyond Absenteeism: Father Incarceration and Child Development

High rates of incarceration among American men, coupled with high rates of fatherhood among men in prison, have motivated recent research on the effects of parental imprisonment on children’s development. We use data from the Fragile Families and Child Wellbeing Study to examine the relationship between paternal incarceration and developmental outcomes for approximately 3,000 urban children. We estimate cross-sectional and longitudinal regression models that control not only for fathers’ basic demographic characteristics and a rich set of potential confounders, but also for several measures of pre-incarceration child development and family fixed effects. We find significant increases in aggressive behaviors and some evidence of increased attention problems among children whose fathers are incarcerated. The estimated effects of paternal incarceration are stronger than those of other forms of father absence, suggesting that children with incarcerated fathers may require specialized support from caretakers, teachers, and social service providers. The estimated effects are stronger for children who lived with their fathers prior to incarceration but are also significant for children of nonresident fathers, suggesting that incarceration places children at risk through family hardships including and beyond parent-child separation.     

Six Rules of Qualitative Research: A Post-Romantic Argument

Qualitative sociology too easily succumbs to a ‘Romantic’ impulse. In a sociological context, the Romantic seeks to understand raw ‘experience’, usually by the use of unstructured interviews. Such work can lack analytic rigour, failing to distinguish the sociologist from the journalist. Following Wittgenstein and Garfinkel, the approach adopted here emphasizes the forms of representation and contexts which inform practical reasoning. It recommends a non-Romantic sociology–an aspiration curiously shared by Durkheim–and suggests some ways to pursue it.     

Shortest confidence and prediction intervals for the log-normal

We provide the shortest prediction interval for X, and the shortest confidence interval for the median of X, when X has the log-normal distribution for both the case σ², the variance of log X, known and unknown. Tables are given to assist the practitioner in constructing these intervals. A real-life example is provided to illustrate the results.     

Quality of life assessment and drug abuse treatment program evaluation

Quality of life assessment is used as an outcome measure technique to evaluate a central medical intake (CMI) unit for drug treatment programs. While significant improvements across time are evident in both perceived well-being and in the standard federal funding criteria, no differences are observed between those referred into treatment by the CMI and those entering directly. Moreover, the improvements observed are the same regardless of whether the patient stayed in treatment or not.     

Market returns? Gender and theories of change in employment relations

This paper explores recent arguments about the marketization of female labour, in the context of a wider analysis of the role of concepts like 'the market' and 'individualization' in sociological accounts of change in employment relations. It will be argued that within sociology there has been a tendency for rapid, large-scale changes in employment relations to be characterized as the breakdown of social influences or structures and as the emergence of atomized, individuated market forces. In the most recent models, change in the nature of gendered positions within employment are presented in terms of a decline of social structuring and social constraint. These emergent accounts hold similarities to classical economics, and to Marx's and Weber's accounts of employment, which also characterized new forms of employment relations in terms of the emptying of their social content and their replacement by market forms. We offer an alternative, moral economy, perspective which foregrounds the continued significance of social relations in the structuring of employment and employment change. We develop the argument through an analysis of gendered patterns of employment and change in family form.     

Do different dimensions of ethnic identity reduce the risk of violence among Asian American and Pacific Islander adolescents in Hawai‘i?

This study examines whether different dimensions of ethnic identity are associated with reduced risk of violence among an understudied population: Asian American and Pacific Islander adolescents. Drawing from survey data of 298 Native Hawaiian, Samoan, Japanese, and Filipino adolescents in Hawai‘i, this study focuses on whether three dimensions of ethnic identity (“affirmation and belonging,” “ethnic identity achievement,” and “other-group orientation”) related to overall and different types of violence. Results of the multivariate analyses reveal that higher levels of ethnic identity achievement are associated with reduced risk of overall violence and family/partner violence, which suggests that this dimension is a beneficial social-psychological resource. Contrary to our expectations, higher levels of ethnic affirmation and belonging are associated with attacking someone. In addition, other-group orientation has no relationship with violence. Implications of our findings regarding distinct effects for different dimensions of ethnic identification are discussed pertaining to developmental research and violence prevention.     

“Right Here is the Gateway”: Mobility,Sex Work Entry and HIV Risk along the Mexico–US Border

Women comprise an increasing proportion of migrants. Many migrate voluntarily for sex work or practise survival sex; others are trafficked for sexual exploitation. To investigate how the context of mobility shapes sex work entry and HIV risk, during 2010 to 2011 we conducted in‐depth interviews with formerly trafficked women currently engaged in sex work (n = 31) in Tijuana and their service providers (n = 7) in Tijuana and San Diego. Women's experiences of coerced and deceptive migration, deportation as forced migration, voluntary mobility, and migration to a risk environment illustrate that circumstances resulting from migration shape vulnerability to sex trafficking, voluntary sex work entry, and HIV risk. Findings suggest an urgent need for public health and immigration policies providing integrated support for deported and/or recently arrived female migrants. Policies to prevent sex trafficking and assist trafficked females must consider the varying levels of personal agency involved in migration and sex work entry.

Policy Implications

• There is a need for coordination between public health and immigration policies to ensure that these are not at odds with one another
• Findings suggest the need for public health and immigration policies that provide integrated support for female migrants, especially trafficked women and girls
• Policy changes are urgently needed to protect deportees' health and promote their social integration
• Policies to prevent sex trafficking and assist trafficked females must consider the range of agencies involved in migration and sex work entry

     

Troubling the Fields: Choice,Consent, and Coercion of Canada's Seasonal Agricultural Workers

This article brings a new, theoretically minded approach to weighing the relative utilities and harms of Canada's Seasonal Agricultural Worker Program (SAWP) without dismissing the agency of SAWP enrollees or arriving at an abolitionist argument to end Temporary Migrant Worker (TMW) programmes in Canada. Building on the anti‐trafficking debate within feminist migration studies, we evaluate the availability and exercise of consent, choice, and coercion among SAWP workers. We draw on extensive documentation by scholars across disciplines to contextualize the SAWP within a socio‐economic history that engendered and continues to legitimize the “success” of the programme in both Mexico (the largest sending state) and Ontario (the largest provincial recipient of workers). Our analysis suggests that, while grievous, the SAWP's structural injustice ought not to preclude individuals from migrating and earning wages. The article concludes with recommendations to create a fairer avenue for Mexican workers into, through, and out of the SAWP.
