A methodology is developed that describes the spatial-temporal trends of economic welfare levels in a region. The focus of the region is assumed to be a key city; that is, a growth pole. The methodology depicts the degree of economic polarization on the pole as time and distance change. Two case studies, Halifax-Dartmouth and its hinterland the Province of Nova Scotia and Quebec City with a hinterland 160 miles in diameter were used to test the methodology. For the 30 year period 1941-1971, the nature of economic growth in the pole cities and their hinterlands and the pole-hinterland growth relationship were determined. Some conclusions regarding the requirements for improved regional welfare levels are offered. The methodology proves itself to be sufficient for the description of spatial-temporal trends in regional welfare levels. These descriptions are suitable for use in preliminary policy formulations and subsequent preliminary plan evaluation. / Thesis / Master of Arts (MA)

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)

Habitat selection by breeding black ducks (Anas rubripes) was studied in Antigonish County, Nova Scotia during April-September 1990 and 1991. / Black duck pairs selected deciduous shrub ponds and sparsely vegetated ponds and avoided estuarine marsh and large lake habitat. Hens with broods preferred the deciduous shrub habitat while they avoided large lakes. / Black duck pairs appeared to use the distance to a brood-rearing pond as a cue in site selection. The closer a pond was to a suitable rearing pond the more likely it was occupied by a pair, regardless of food or cover resource availability. Black ducks, however, likely used site attributes such as the perimeter of the pond, the availability of aquatic invertebrates and the relative abundance of alder, willow and dead timber as cues in the selection brood-rearing habitat. / Black duck duckling survival, an estimate of recruitment, was the highest on preferred deciduous shrub ponds. Duckling survival was also higher on ponds with only one brood as opposed to ponds with several broods. / The most productive habitat for black ducks in the Antigonish study area were isolated, deciduous shrub ponds influenced by beaver activity. Black duck population numbers can be enhanced by managing local beaver populations.

In this qualitative research study, First Nation students in high school participated in an interview study designed to (1) describe how their school experiences related to academic success and (2) to identify learning strategies used to achieve success. Participants described the importance of achieving academic success to ensure future economic security. In their approaches to learning, participants preferred multiple modes of learning. Various types of learning strategies included both visual and verbal methods such as teacher demonstrations, reading, and writing. Motivational influences were also identified as contributing to their educational success which came from a variety of sources such as teachers, parents, peers, and community leaders. Educational success for these Aboriginal students is both multi-dimension and multi-modal. Implication of the research and future direction will be discussed.
