Cleaning up their act: The effects of marriage and cohabitation on licit and illicit drug use

We use data from the National Longitudinal Survey of Youth to estimate changes in binge drinking, marijuana use, and cigarette smoking surrounding young adults' first experiences of cohabitation and marriage. Both marriage and cohabitation are accompanied by decreases in some risk behaviors, but reductions surrounding marriage are larger and most consistent, particularly for men. Binge drinking and marijuana use respond to these events, especially marriage, but smoking does not.     

Methods for Detecting and Estimating Population Threshold Concentrations for Air Pollution–Related Mortality with Exposure Measurement Error

The association between daily fluctuations in ambient particulate matter and daily variations in nonaccidental mortality have been extensively investigated. Although it is now widely recognized that such an association exists, the form of the concentration–response model is still in question. Linear, no threshold and linear threshold models have been most commonly examined. In this paper we considered methods to detect and estimate threshold concentrations using time series data of daily mortality rates and air pollution concentrations. Because exposure is measured with error, we also considered the influence of measurement error in distinguishing between these two completing model specifications. The methods were illustrated on a 15-year daily time series of nonaccidental mortality and particulate air pollution data in Toronto, Canada. Nonparametric smoothed representations of the association between mortality and air pollution were adequate to graphically distinguish between these two forms. Weighted nonlinear regression methods for relative risk models were adequate to give nearly unbiased estimates of threshold concentrations even under conditions of extreme exposure measurement error. The uncertainty in the threshold estimates increased with the degree of exposure error. Regression models incorporating threshold concentrations could be clearly distinguished from linear relative risk models in the presence of exposure measurement error. The assumption of a linear model given that a threshold model was the correct form usually resulted in overestimates in the number of averted premature deaths, except for low threshold concentrations and large measurement error.     

Professional development laboratory: center for literacy and community services

We developed three Professional Development Laboratories: Centers for Literacy and Community Services that addressed four pressing needs in the current urban school crisis: the preparation of in-service teachers to be literacy specialists, the dire need for qualified teachers in urban settings, the professional development of uncertified urban teachers, and the literacy needs of the children and families these teachers serve. These centers were housed in three inner-city schools rather than at the university and thus were able to serve larger numbers of children. Since many of the teachers in these schools are novice or uncertified teachers, we offered on-site in-service courses in order to enhance their ability to help their students. By housing the Centers for Literacy and Community Services on site in the schools, we sought to reach students and families who might otherwise not be able to avail themselves of these services. Unique to this project was that our graduate literacy education students tutored students on site in schools, the university faculty worked alongside the graduate students, and both students and faculty provided services to enhance the professional development of teachers and administrators in the area of literacy. Additionally, this project was distinguished by the inclusion of a component designed to provide literacy education services to the families and caregivers of the children.     

The detection of annual clusters in individual patterns of parasuicide

The anniversary model for the annual repetition of parasuicide (attempted suicide) is described. In order to demonstrate the existence of such effects in individuals, the Range Test for circular data is applied to data collected over a 2-year period from a specific case from the Edinburgh Regional Poisoning Treatment Centre. The use of this model in predicting future clusters of parasuicide episodes is then discussed.     

The social inclusion policy agenda in Australia: a case of old wine,new bottles?

The election of an Australian Labor Government in Australia in 2007 saw ‘social inclusion’ emerge as the official and overarching social policy agenda. Being ‘included’ was subsequently defined by the ALP Government as being able to ‘have the resources, opportunities and capabilities needed to learn, work, engage and have a voice‘. Various researchers in Australia demonstrated an interest in social inclusion, as it enabled them to construct a multi‐dimensional framework for measuring disadvantage. This research program resulted in various forms of statistical modelling based on some agreement about what it means to be included in society. The multi‐dimensional approach taken by academic researchers, however, did not necessarily translate to a new model of social policy development or implementation. We argue that, similar to the experience of the UK, Australia's social inclusion policy agenda was for the most part narrowly and individually defined by politicians and policy makers, particularly in terms of equating being employed with being included. We conclude with discussion about the need to strengthen the social inclusion framework by adopting an understanding of social inequality and social justice that is more relational and less categorical.
