A Statistical Investigation Presented by Stephen Walter, McMaster University A European randomised trial of PSA screening has shown a substantial reduction in prostate cancer mortality. Accurate adjudication of the underlying cause of death is crucial for a conclusive evaluation of the effectiveness of screening, but there is no gold standard, and a major challenge is the potential misattribution of the cause of death in elderly men with multiple comorbidities. In order to determine if misclassification of causes of death might have biased the results, we analysed the variation between the trial adjudicators in six participating countries. Latent class models were formulated to estimate the accuracy of adjudication, and to assess if accuracy might have been differentially favourable to one or other of the randomised study arms. Finally we used the model to evaluate if correcting for variability in adjudication might substantially South Studio 3 modify the main trial results on the effect of screening on the rate of prostate cancer death. Targeted inference: Aligning Statistical Tools with Epidemiologic Goals Presented by Robert Platt, McGill University This session will address the goals of inference in epidemiology, and propose “targeted inference” as a general paradigm for efficient inference. In general, traditional statistical methods and epidemiologic designs, as typically used, do not focus on parameters of interest. Participants will hear about newer methods for epidemiologic inference designed to focus on key, well-defined parameters of interest, and to be efficient and robust to mis-specification of non-essential components of the statistical model. Robert Platt will illustrate the use of these methods through examples in pharmacoepidemiology. 6 SP2 VIOLENCE PREVENTION Violence Reduction, Paradigms and Pragmatism Presented by Peter Donnelly, MD, President and CEO Public Health Ontario Greenwich Room To describe the importance of violence reduction as a Public Health issue. To discuss concepts in violence reduction and share challenges in undertaking pragmatic research in this area. SP3 PUBLIC HEALTH RESPONSE TO EBOLA All Epidemics are the Same, All Epidemics are Different: Lessons Learned from Ebola Presented by David N. Fisman, Professor of Epidemiology, Dalla Lana School of Public Health, Dalla Lana School of Public Health The 2014-14 West African Ebola outbreak has sickened tens of thousands of individuals in Liberia, Sierra Leone and Guinea. Efforts to model and forecast epidemic growth were hampered by limited data, as well as the inability of forecast models to anticipate changes in population attitudes, behaviors and knowledge. At the same time, we know that in general terms, epidemics, and human responses to epidemics, have important commonalities. I will describe our efforts to model and forecast the Ebola epidemic, and show that our current approach was anticipated by epidemiologists dealing with similar challenges in the 19th century. Brittania Room The Owl of Minerva: Are lessons ever truly learned? Presented by Ross Upshur, Professor, Department of Family and Community Medicine and Dalla Lana School of Public Health, Canada Research Chair in Primary Care Research During this session, participants will hear a review of the West Africa Ebola Virus Disease outbreak through the lens of experience gained in the past two decades of involvement in infectious disease outbreaks of global significance. Ross Upshur will raise questions as to how organizations interact both positively and negatively. The expected outcome would be for epidemiologists to be sensitized to the difficulties of institutional memory with the hope that they will not suffer the same lapses in their careers. 12:00pm – 1:00pm NETWORKING LUNCH & POSTER VIEWING (View Poster Presentations Guide on pages 59 & 66) Graydon Ballroom 12:00pm – 1:00pm LUNCH WORKSHOP Epidemiology and Public Policy: The role of the International Joint Policy Committee of the Societies of Epidemiology (IJPC-SE) Presented by Mark Oremus, Communications Officer, IJPC-SE and Vice President, CSEB; and Colin Soskolne, Professor emeritus, University of Alberta; Adjunct Professor, Faculty of Health, University of Canberra; Chair, International Joint Policy Committee of the Societies of Epidemiology The IJPC-SE is a consortium currently including 18 epidemiology societies whose mandate is to facilitate and coordinate Greenwich Room joint policy actions among its member societies. The IJPC-SE is internationally known for having most recently developed a position statement that puts forth, from an epidemiological perspective, clear evidence confirming that all forms of asbestos should be banned. This statement was developed in response to the fact that some countries continue to promote the “safe use” of asbestos. The purpose of the symposium is to highlight the role of the IJPC-SE in public policy and its modus operandi. More broadly, the symposium

  • Transportation Infrastructure and Regional Development in Northern Manitoba
    Transportation Infrastructure and Regional Development in Northern Manitoba: Realities and Prospects by Stephen Pratte A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of MASTER OF ARTS Department of Environment and Geography University of Manitoba Winnipeg © 2012 Copyright by Stephen Pratte Abstract The relationship between transportation and economic development is well documented. Two requirements indispensable to this relationship are access (ability to reach a place) and connectivity (relationship of the place to others). The interaction of people and markets via transportation infrastructure facilitates trade and increased social interaction; all vital for development. This thesis examines the nature of access and connectivity of the multi-modal transport network (i.e. road, rail, water and air modes) of Northern Manitoba, a study area characterized by many small communities distributed in a vast area, with some having no year-round overland access, forcing them to rely on the seasonally constructed winter road system. Models of the four modal networks (graph theory) are used to analyze the transportation ’s structure, accessibility and connectivity for specific points in time with a view to network understand network change. Recommendations are offered that would facilitate the integration of transportation planning. i Acknowledgements Several acknowledgements of gratitude are required of those who guided the production of this thesis. First, to my thesis and program advisor Dr. Daniel Todd, whose insight and perspectives on the spheres of transport and development, and the ongoing discussions thereof, have been invaluable, both from a research and professional perspective.

  • 2.0 Native Land Use - Historical Period
    2.0 NATIVE LAND USE - HISTORICAL PERIOD The first French explorers arrived in the Red River valley during the early 1730s. Their travels and encounters with the aboriginal populations were recorded in diaries and plotted on maps, and with that, recorded history began for the region known now as the Lake Winnipeg and Red River basins. Native Movements Pierre Gaultier de Varennes et de La Vérendrye records that there were three distinct groups present in this region during the 1730s and 1740s: the Cree, the Assiniboine, and the Sioux. The Cree were largely occupying the boreal forest areas of what is now northern and central Manitoba. The Assiniboine were living and hunting along the parkland transitional zone, particularly the ‘lower’ Red River and Assiniboine River valleys. The Sioux lived on the open plains in the region of the upper Red River valley, and west of the Red River in upper reaches of the Mississippi water system. Approximately 75 years later, when the first contingent of Selkirk Settlers arrived in 1812, the Assiniboine had completely vacated eastern Manitoba and moved off to the west and southwest, allowing the Ojibwa, or Saulteaux, to move in from the Lake of the Woods and Lake Superior regions. Farther to the south in the United States, the Ojibwa or Chippewa also had migrated westward, and had settled in the Red Lake region of what is now north central Minnesota. By this time some of the Sioux had given up the wooded eastern portions of their territory and dwelt exclusively on the open prairie west of the Red and south of the Pembina River.

  • Network Evolution: the Origins, Development And
    Network Evolution: The Origins, Development and Effectiveness of ’s Railway System Manitoba by Christopher G. L. McCombe A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfillment of the requirements of the degree of MASTER OF ARTS Department of Environment and Geography University of Manitoba Winnipeg, Manitoba © 2011 by Christopher McCombe Copyright ABSTRACT This thesis examines the changing characteristics of railway infrastructure development and associated issues in the province of Manitoba, Canada. The period under consideration dates from when the first tracks were laid in 1878 through to the completion of the Hudson Bay Railway in 1929. Setting the scene is a template for railway development in general, one that allows hypotheses to be drawn that are specific to Manitoba. In order to test those hypotheses it is necessary to first provide a comprehensive overview of the historical evolution of the railway network. Next, the tools for testing the hypotheses as to how that network emerged have to be reviewed. That review examines aspects of graph theory, identifying the methodology most appropriate for a spatial analysis of railway networks. With the fundamental assumption in mind that no railway system of any real complexity can be effectively understood without considering the process of its creation, this analysis attempts to draw conclusions about the relationship between the railway companies and the governments, people and geography that they were compelled to deal with. Given that objective, an emphasis is placed during hypothesis testing on a set of geographic forms developed by prominent geographer Donald Meinig, who set the precedent in the field of railway-network geography.
