The Effect of Combining Insecticide Treated Nets and Indoor Residual Spraying for Vector Control of Malaria: A Systematic Review

Creator:: Feng, Jonathan
Abstract:: Throughout a large portion of our planet, malaria has been nearly eradicated or reduced to levels that are highly manageable, and many countries possess the means to effectively treat the disease. However, many areas of the world, such as Sub-Saharan Africa and Southeast Asia, are still heavily burdened by malaria....

Development of an instrument assessing ATV use among Oregon's youth on ranches and farms

Creator:: Iggulden, Kathryn G., White, David, and Bethel, Jeff
Abstract:: During the 1980s the sales and use of all-terrain vehicles (ATVs) was on the rise. Many people used them for recreation, while others started using them on their ranch or farm for work-related purposes. As a result, morbidity and mortality rates also began to climb. It became apparent that the...

The Association Between Extreme Climate and Diarrheal Illness in North America

Creator:: Lyon-Colbert, Amber
Abstract:: The etiology and transmission of bacterial diarrheal pathogens is complex, making evaluating the association between extreme climate and diarrheal illnesses in North America challenging. Changes in climate may impact the survival, reproduction, and distribution of pathogens that cause diarrheal illness. Evidence supports the hypothesis that reproduction, survival, and transmission ability...

The Identification of Common Environmental and Demographic Associations for Tick-Borne Disease Risk and Surveillance Efforts in the United States

Creator:: Ashraf, Benjamin J.
Abstract:: Ixodes scapularis (e.g. blacklegged tick) is a hard-bodied tick considered endemic to certain regions within the United States. This species is considered a primary vector of Lyme disease (Borrelia burgdorferi), anaplasmosis (Anaplasma phagocytophilum) and babesiosis (Babesia microti). Each of these tick-borne diseases represent a growing health concern within the nation...

Mortality Associated with Short- and Long-Term Temperature Changes: A Global Evaluation within the Prospective Urban Rural Epidemiology Study

Creator:: Bigouette, John P.
Abstract:: The influence of increasing temperatures on human health has been widely established across multiple health disciplines. Short-term temperature changes are associated with an increased risk of hospitalization and death overall and in a variety of health conditions, such as cardiovascular disease. Even as humans can self-regulate heat stresses, the elderly,...

Heat-Related Illness among Oregon Farmworkers

Creator:: Bethel, Jeffrey W. and Harger, Renee
Abstract:: Farmworkers are particularly vulnerable to climate-sensitive health outcomes such as heat-related illness (HRI) given their tasks involve heavy exertion in an outdoor setting. The objectives of the study were to: (1) describe symptoms of HRI experienced by farmworkers and (2) explore factors associated with heat knowledge, level of concern regarding...

Optimization of Wastewater Sampling and Concentration Methods to Accurately Detect and Quantify SARS-CoV-2 in Varying Scales of Catchment

Creator:: George, Andrea D.
Abstract:: At the beginning of the COVID-19 pandemic, the world was unprepared for such a massive challenge to global health. Individual testing kits and personal protective equipment were scarce. There were minimal ways to track the rapid spread of the disease, until researchers discovered that SARS-CoV-2, the virus that causes COVID-19,...

Novel Extensions and New Applications for Nonparametric Self-Exciting Point Processes

Creator:: Boyd, Peter C.
Abstract:: In this dissertation I will demonstrate a novel application of self-exciting point process models to mass shooting data. I will also introduce two adaptations to the traditional nonparametric Hawkes process modeling framework. One such modification allows for the estimation of the additional productivity introduced by an event that is not...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...
