Leptospira Seroprevalence In Companion Animals In Tennessee, Kellie Anne Mccreight

Masters Theses

Leptospirosis is a re-emerging zoonotic disease in humans and animals. The bacteria Leptospira spp. causing this disease is maintained in the kidneys of animals such as rodents and cattle as well as in the environment. Animals harboring Leptospira spp. in the kidneys frequently shed the bacteria in their urine, contaminating the environment. Contact with contaminated soil and water may result in infection. Animals and humans may develop serious life threatening disease from Leptospira infection. Approximately 1 million new human cases and over 50,000 deaths are reported worldwide. Numerous animal species including rodents, cattle, and dogs may serve as reservoir …

A Machine Learning Approach For Predicting Clinical Trial Patient Enrollment In Drug Development Portfolio Demand Planning, Ahmed Shoieb

Masters Theses

One of the biggest challenges the clinical research industry currently faces is the accurate forecasting of patient enrollment (namely if and when a clinical trial will achieve full enrollment), as the stochastic behavior of enrollment can significantly contribute to delays in the development of new drugs, increases in duration and costs of clinical trials, and the over- or under- estimation of clinical supply. This study proposes a Machine Learning model using a Fully Convolutional Network (FCN) that is trained on a dataset of 100,000 patient enrollment data points including patient age, patient gender, patient disease, investigational product, study phase, blinded …

Association Between Stream Impairment By Mercury And Superfund Sites In The Conterminous Usa, Karessa L. Manning

Do Increases In Fruit Intake Lead To Substitutive Eating Patterns And Decreases In Overall Energy Intake In Normal Weight Adults?, Shireen Amanda Sobhani

Masters Theses

Background: It is suggested that increasing intake of fruits and vegetables may lead to decreased energy intake via substitution of higher energy-dense foods, such as snack foods (SF; i.e. candy, chips, cookies). This study investigated the impact of increasing fruit (F; grapes) intake, via increased portion size, on SF (potato chips) intake during a meal and whether increases in F intake affected total meal energy intake, via reducing SF intake (substitutive eating), in normal-weight adults. A secondary objective investigated whether the relative reinforcing value (RRV) of SF was a moderator of the substitutive relationship between F and SF.

Methods: Using …

Latin Hypercube Sampling And Partial Rank Correlation Coefficient Analysis Applied To An Optimal Control Problem, Boloye Gomero

Masters Theses

Latin Hypercube Sampling/Partial Rank Correlation Coefficient (LHS/PRCC) sensitivity analysis is an efficient tool often employed in uncertainty analysis to explore the entire parameter space of a model. Despite the usefulness of LHS/PRCC sensitivity analysis in studying the sensitivity of a model to the parameter values used in the model, no study has been done that fully integrates Latin Hypercube sampling with optimal control analysis.

In this thesis, we couple the optimal control numerical procedure to the LHS/PRCC procedure and perform a simultaneous examination of the effects of all the LHS parameter on the objective functional value. To test the effectiveness …

Active Video Gaming Compared To Unstructured, Outdoor Play In Children: Measurements Of Estimated Energy Expenditure And Measured Percent Time In Moderate-To-Vigorous Physical Activity, Susan Brittin Macarthur

Masters Theses

It is recommended that children and adolescents participate in > 60 minutes of moderate-to-vigorous physical activity (MVPA) per day. Despite the current recommendations and positive health benefits, many children and adolescents still do not engage in regular physical activity (PA).

One challenge for assisting children in becoming more active is sedentary screen-based activities (SBAs), such as watching television (TV), using computers, and playing sedentary video games (VGs), as SBAs may compete with time for being physically active in children. One modification to sedentary VGs that may increase PA in children is to alter them so that the VGs actually provide an …

Spatial Epidemiology And Temporal Trends Of Heart Attack And Stroke In Middle Tennessee, Doreen Busingye

Masters Theses

Despite declines in mortality risks of myocardial infarction (MI) and stroke in the US since the 1960’s, the burdens of these conditions remain high. These conditions require emergency and specialized care and therefore quick transportation of patients to appropriate hospitals is critical. Geographic disparities in MI and stroke burdens have been consistently reported in the US with the south-east having the highest risks. Most studies of geographic disparities have been performed at county or higher geographic units. Therefore, spatial patterns at neighborhood levels are unclear. Moreover, it’s important to investigate disparities at neighborhood levels to better understand neighborhood health needs. …

Some Observations On The Health Program In Clinton High School With Particular Emphasis On The Needs Of The Students, Eloise Harris Wynne

Masters Theses

The Problem: Education progressed from the study of the classics by a few, to the learning of the three R's by many, and more lately has expanded to include not only intellectual development but also other phases of man's personality. From this view point:

Education . . . has recognized that individuals are whole personalities. . . . . Schools and community agencies, therefore, should be concerned not only with the individuals' intellectual development and needs but also with his social, emotional, physical, aesthetic, and ethical development and needs.

Health is of primary importance in the development of the individual …
