Impacts And Feasibility Of The Us And The Eu Sustainability Criteria On Existing Land-Use Practices, Krissana Treesilvattanakul
Open Access Dissertations
Several studies have examined the land use and economic consequences of national and multi-national biofuel policies. They explored the impacts of biofuels mandates mainly based on the quantitative biofuel targets. However, the recently updated renewable policies of the United States and the European Union, which are the US Renewable Fuel Standard (RFS) and EU Directive 2009/28 of the Renewable Energy Directive (RED) both place restrictions on land that can be used to produce biofuel, and these restrictions are generally known as sustainability criteria. This research aims to determine to what extent sustainability criteria are actually binding; that is, would they …

Impact Of Hydraulic Fracturing On Ground And Surface Water Resources, Reyna Schenck
Natural Resources Management and Environmental Sciences
The following study examines hydraulic fracturing operations in the United States in relation to groundwater contamination, withdrawals of freshwater resources, and jurisdictional authority over the activity with the purpose of producing objective analysis of research findings. With a growing population and increasing energy needs, hydraulic fracturing is expanding across the nation, as is public concern over the risks to freshwater resources. Because of the difficulty in identifying non-point sources of water pollution, a lack of legitimate water samples representing baseline conditions, and incomplete lists of chemical additives used, study results are often inconclusive as to the correlation between hydraulic fracturing …

Classroom Exercise Breaks And Educational Outcomes In Elementary School Students, Erin Kaye Howie
Theses and Dissertations
Previous research has shown that physical activity may have beneficial effects on cognitive performance and academic achievement in children, but the optimal type and dose are unknown. Classroom exercise breaks are one type of physical activity opportunity in schools, with the potential to reach a large number of children. The purpose of this dissertation was to describe the prevalence and characteristics of classroom exercise breaks in central South Carolina, and to determine the acute effects of classroom exercise breaks on executive functions, math performance, on-task behavior and affective responses in 9 to 12 year-old children. Additionally, the dissertation examined the …
Measuring Organizational Member Involvement In Physical Activity Coalitions Across The United States, Daniel Benjamin Bornstein
Measuring Organizational Member Involvement In Physical Activity Coalitions Across The United States, Daniel Benjamin Bornstein
Theses and Dissertations
Physical inactivity has been labeled a global pandemic with enormous economic, social, environmental, and public health consequences. The vast majority of American adults and youth are insufficiently physically active. Increasing population-levels of physical activity (PA) requires broad social and environmental change. PA coalitions provide the structure through which such broad change can be achieved. An extensive literature on health-based coalitions suggests that coalition success is impacted by coalition members. Coalitions are generally comprised of member organizations. Little is known about the characteristics of PA coalitions and less is known about organizational member involvement in PA coalitions. The purpose of this …
