Evaluating Employees’ Experiences In Implementing Covid-19 Safety Protocols In Ontario Parks, Jessica Kaatz
Evaluating Employees’ Experiences In Implementing Covid-19 Safety Protocols In Ontario Parks, Jessica Kaatz
Theses and Dissertations (Comprehensive)
The COVID-19 pandemic has created a wide range of public health challenges for park management and staff in Ontario. Green spaces have become a source of resilience during the spread of the virus, partly due to their proven positive impacts on social, mental and physical well-being. With the introduction of social distancing protocols, utilization of Personal Protective Equipment (PPE), and standardizing constant sanitation efforts, park employees are more responsible than ever for the daily implementation of rules governing park safety and security. At the same time, increased visitor numbers and continually changing government protocols that varied between regional jurisdictions have …
Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee
Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee
Theses and Dissertations (Comprehensive)
Wildlife data is often limited by survey effort, small sample sizes, and spatial biases associated with collection and missing data. These factors can create unique challenges from a surveillance perspective when trying to extract spatial patterns of habitat suitability and disease distributions for conservation and management purposes. This thesis examined data quality from a wildlife health database in the context of spatial analysis of wildlife disease. Spatial analysis of the data to predict habitat suitability of bats and white nose syndrome afflicted bats was examined by using the MaxEnt modelling method. Methods to reduce spatial bias were examined and specific …
Space-Time Modelling Of Emerging Infectious Diseases: Assessing Leptospirosis Risk In Sri Lanka, Cameron C F Plouffe
Space-Time Modelling Of Emerging Infectious Diseases: Assessing Leptospirosis Risk In Sri Lanka, Cameron C F Plouffe
Theses and Dissertations (Comprehensive)
In this research, models were developed to analyze leptospirosis incidence in Sri Lanka and its relation to rainfall. Before any leptospirosis risk models were developed, rainfall data were evaluated from an agro-ecological monitoring network for producing maps of total monthly rainfall in Sri Lanka. Four spatial interpolation techniques were compared: inverse distance weighting, thin-plate splines, ordinary kriging, and Bayesian kriging. Error metrics were used to validate interpolations against independent data. Satellite data were used to assess the spatial pattern of rainfall. Results indicated that Bayesian kriging and splines performed best in low and high rainfall, respectively. Rainfall maps generated from …
Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka
Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka
Theses and Dissertations (Comprehensive)
Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus' amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that …
Health And Development: Infectious Intestinal Diseases In A Transborder Region (United States-Mexico), Flavia Bianchi
Health And Development: Infectious Intestinal Diseases In A Transborder Region (United States-Mexico), Flavia Bianchi
Theses and Dissertations (Comprehensive)
Intestinal infectious diseases are considered the northern Mexican border’s most obvious challenge facing children. The Mexico-US Border region is a 200-kilometer border zone that extends 100 kilometers on either side of an imaginary borderline and stretches 3,141 kilometers from the Pacific Ocean to the Gulf of Mexico. In 2000, the Pan American Health Organization (PAHO), the World Health Organization’s representative for the Americas, published a study of the top causes of mortality between 1995 and 1997 to estimate the absolute burden of mortality in the primary Mexican and American border community, collectively known as the Sister Cities. Using the PAHO …
Obstetrical Care In The Baffin Region, Northwest Territories: Geographical, Medical And Cultural Perspectives, Christine Clara Earnshaw
Obstetrical Care In The Baffin Region, Northwest Territories: Geographical, Medical And Cultural Perspectives, Christine Clara Earnshaw
Theses and Dissertations (Comprehensive)
In the Baffin Region, and other regions of the Canadian Arctic, geographic impediments and the history of southern-based health care delivery have influenced the present health care delivery and service. This is especially the case for obstetrical care since the whole process of childbirth has been transformed into a medical issue administered mainly by southern, non-Inuit health care workers and policy makers. Using 350 maternal and infant health records from the Baffin Regional Hospitals from September 1993 to September 1994, variables such as maternal age, fertility rates and low birth weight rates were calculated for communities in the region to …
Pandemic Influenza: An Analysis Of The Spread Of Influenza In Kitchener, October 1918 (Ontario), Niall Phillip Alan Sean Johnson
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 …
