The major objective of the research is to assess the risk of preterm birth associated with maternal proximity to hazardous waste and pollution from the Sydney Tar Pond sites in Nova Scotia, Canada. The design is spatial modelling of risks of preterm birth in population living in the Cape Breton regional municipality in 1996. The subjects are: 1604 observed cases of preterm birth out of total population of 17559 at risk in 1996. The analysis was done using both the frequentist and the Bayesian approaches. In the frequentist approach, the Poisson model for aggregated data was fitted using the quasi-likelihood approach to accommodate over-dispersion. Weighted regression was also used. In order to accommodate both the random effect and the anticipated spatial effects, Bayesian hierarchical modelling was also used to fit the Poisson model. The result of the Bayesian modelling shows that there is no significant spatial association of risk in the area studied. All the models also show that there is no decrease in risk of preterm birth as we move from the Tar Pond site to other region. None of the other covariates in the model show any significant association with increase risk of preterm birth either. There was no obvious clustering of risk in any region or part. / Thesis / Master of Science (MS)

Decades of steel production and coking in the community of Sydney, Nova Scotia, have led to severe environmental insult. Increased amounts of air pollution from Sydney Steel Corporation and toxic emissions from the Muggah Creek Watershed have been well documented in several studies of the area since the 1960s. This research examines the potential impacts of exposure to hazardous waste on the reproductive health of women living in Cape Breton Regional Municipality through the following objectives: i) to assess the spatial pattern of various types of adverse reproductive events, plausibly linked to the environmental exposure of interest; ii) to determine if this pattern is related to proximity to the Tar Ponds/Coke Ovens site. To address the first objective, point pattern analysis was applied to observations from the Atlee Perinatal Database to determine if the observed pattern exhibited any clustering. To address the second objective, a multinomial logistic regression model was employed to determine if proximity to the Tar Ponds/Coke Ovens site was an important covariate of the adverse outcomes under study (preterm births, low birthweights, congenital anomalies and stillbirths). The results of the bivariate K-function indicated that there was weak global clustering for preterm births for two different time periods, while the ratio kernel estimates demonstrated that the patterns of the outcomes were non-random even after correcting for the underlying population distribution. The results of the multinomial logistic model demonstrated that variables pertaining to maternal characteristics, pregnancy history, current pregnancy maternal diagnoses, neonatal measures were important explanatory variables in the analysis. Place of residence was an important explanatory variable for preterm births and congenital anomalies. However, due to various limitations these results must be interpreted with caution. / Thesis / Master of Arts (MA)

The existence of racism in Canada is well documented (Johnson and Enomoto 2007; Henry and Tator 2006; Lopes and Thomas 2006), yet little is known about the employment experiences of those marginalized by race. In a study looking at African Canadians’ experiences of racism related stress, James, Este, Bernard, Benjamin, Lloyd and Turner (2010), found that racism in the employment sector was one of the most significant areas of stress faced by the study participants. Given these findings, this qualitative study sought to further explore the everyday employment experience of adults in Nova Scotia, who are marginalized by race. In addition, it sought to foster deeper understandings of the influence of employment equity policy on organizational change.

Urban highway infrastructure in North America has been singularly designed for the automobile, severing parts of the urban fabric, blighting our once-thriving city centres and resulting in spaces that are void of the human scale. The Cogswell Interchange in Halifax, Nova Scotia, Canada is such an infrastructure, cutting through the downtown core and heritage district. This thesis investigates the Cogswell Interchange in an attempt to animate and enliven a dead urban space, reducing traffic and bringing new activity and life to the street. Reappropriating parts of vehicular infrastructure for cyclist and pedestrian use and creating a variety of activities and programs (gallery, gym, restaurant, park) enables an increased connectivity for pedestrians and cyclists and brings a more human-scale urbanity to the site. The infrastructure itself becomes a framework upon which to build, revisioned as an active, vibrant place which people can experience with a renewed sense of wonder and appreciation.
