Voronoi Diagrams As A Visualization Technique For Spatial Autocorrelation In Point Data Sets, Martin A. Cassel Jan 1993

Voronoi Diagrams As A Visualization Technique For Spatial Autocorrelation In Point Data Sets, Martin A. Cassel

Theses and Dissertations (Comprehensive)

This thesis explores a new way of visualizing spatial autocorrelation in a GIS environment. It explores some relationships between spatial autocorrelation models, spatial interaction models and weighted Voronoi diagrams. Since the weighted Voronoi diagram is equivalent to a form of spatial interaction models, any GIS with the ability to generate a gravity model can be utilized to perform this new technique of exploratory spatial data analysis. This thesis demonstrates how the cross product form of‘ spatial autocorrelation models like the Geary and the Moran statistics is equivalent to the form of a multiplicatively weighted distance utilized in the definition of …


Theoretical And Empirical Examinations Of Spatial Scale And Aggregation Effects On The Principal Axis Factoring Technique When The Observations Are Areal Units, Len Michael Hunt Jan 1993

Theoretical And Empirical Examinations Of Spatial Scale And Aggregation Effects On The Principal Axis Factoring Technique When The Observations Are Areal Units, Len Michael Hunt

Theses and Dissertations (Comprehensive)

Previous assessments of factor analytic invariance to scale and aggregation effects have led to discrepant results. To determine the true effects, this study comprehensively examines the influence of scale and aggregation on factorial ecologies. This investigation is completed for three data sets, four scales, and thirty aggregations at each scale. Of these three data sets, two are artificial. These two data sets differ only by levels of spatial autocorrelations as one data set contains independent areal unit observations while the other set includes modest positive spatial autocorrelations. The third data set consists of variables from the 1986 Saskatoon enumeration areas. …


An Analysis Of Canadian International & Interprovincial Manufacturing Export Flows: 1974-1990, H. Lillian Kucsma Jan 1993

An Analysis Of Canadian International & Interprovincial Manufacturing Export Flows: 1974-1990, H. Lillian Kucsma

Theses and Dissertations (Comprehensive)

This thesis examined the changing internal and external export patterns of Canadian manufactured products in the years 1974, 1979, 1984, and 1990. Hechscher—Ohlin's comparative advantage trade framework was used to guide the analysis. Internally, provincially biased shipping patterns were found over the four time periods analyzed. The percentage of intraprovincial shipments increased, and interprovincial shipments decreased through time. This suggests that the provinces exhibited signs of increasing provincialism. Externally, except for 1990, primary export flow destinations to the USA as a percentage of total exports increased over time while those to the other OECD countries decreased. Secondary export flow destinations, …


Agro-Climatic Hazards And The Political Economy Of Food Insecurity In West Africa: A Case Of A Rural Food Economy, Raphael Lawer Djabatey Jan 1993

Agro-Climatic Hazards And The Political Economy Of Food Insecurity In West Africa: A Case Of A Rural Food Economy, Raphael Lawer Djabatey

Theses and Dissertations (Comprehensive)

Variability and declining food production and accessibility in West Africa have characterised the food system in the region’s rural economy. These phenomenon have contributed to the fluctuation and declining per capita food supply and calorie intake, falling wages of farmers, rising food prices and increasing reliance on food imports and food aid by the governments and people of West Africa. The cause of the problem still remains an illusion and continues to baffle policy makers. Very often the problem is attributed to drought. However, to reduce the problem of household food insecurity to natural forces is to miss the centre …


Pandemic Influenza: An Analysis Of The Spread Of Influenza In Kitchener, October 1918 (Ontario), Niall Phillip Alan Sean Johnson Jan 1993

Pandemic Influenza: An Analysis Of The Spread Of Influenza In Kitchener, October 1918 (Ontario), Niall Phillip Alan Sean Johnson

Theses and Dissertations (Comprehensive)

Influenza remains one of the major killers in modern society. In addition to the mortality it causes, it exacts a huge medical, social and economic toll. Due to its propensity to undergo change, through antigenic drift and shift, this disease continues to torment humankind. These changes are the driving force that enables influenza to periodically become epidemic and pandemic. The study of past pandemics thus may provide useful insight to comb-it the disease now and in the future. The 1918-19 pandemic is one of the three worst outbreaks of disease in recorded history, with only the Justinian plagues and the …
