For the semiotic analysis, one commercial from each of the four selected years was chosen to …


Using Empathy In Design To Foster Interest In Social Issues, Kofi Opoku May 2013

Using Empathy In Design To Foster Interest In Social Issues, Kofi Opoku

Graduate Theses, Dissertations, and Problem Reports (ETD)

Design has transformed from being merely a product oriented discipline focused on the promotion of consumer goods to become a goal oriented practice seeking to address the needs and challenges faced by people in their communities. Conventionally, most designers have engaged various processes that help identify the real needs of an audience in order to develop effective solutions. Designing for social change presents the interesting challenge of reaching audience members who may not be directly affected by an issue to become invested in communityled transformations. My thesis uses the context of homelessness to examine how empathic techniques can be employed …

Assessment Of Hyporheic Exchange At In-Stream Restoration Structures On Savage River, Garrett County, Maryland, Anna L. Berlinghieri May 2013

Assessment Of Hyporheic Exchange At In-Stream Restoration Structures On Savage River, Garrett County, Maryland, Anna L. Berlinghieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous studies have shown that in-stream restoration structures alter hyporheic exchange dynamics in restored channels; this study assessed hyporheic exchange at a recently constructed stream reach, including the effects of in-stream restoration structures. Hydrometric and thermal data were collected in the streambed near three restoration structures and at a reference site. The hydrometric data indicated that hyporheic flow paths may not have fully developed in the first 16 months following construction; only one in-stream piezometer was unambiguously hydraulically connected to changes in stream stage. Other hydrometric data revealed possible piezometer installations in low permeability materials, potential hydraulic connections to an …

Spring Studies And A Decision-Making Process To Guide Groundwater Contamination Prevention In An Agricultural Karst Basin, Erin D. Murphy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Groundwater contamination is a potential major health and environmental issue in karst aquifers because of rapid surface water to groundwater connections and conduit-dominated flow that may allow contaminants to move great distances from their source in a very short amount of time. Agricultural contaminants are a significant problem in Buckeye Creek basin in Greenbrier County, West Virginia. Pasquarell and Boyer (1995) found that cattle grazing near sinking streams, sinkholes, and springs contribute to the elevated levels of fecal coliform bacteria in the groundwater. Six sites in Buckeye Creek basin were monitored for fecal coliform contamination and then analyzed in order …

From Gunboats To Good Neighbors: U.S. Naval Diplomacy In Peru, 1919-1942, Joel C. Christenson

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines the role naval power played in the evolution of U.S. policy toward Latin America during the interwar period, when the United States abandoned armed interventionism in favor of the policy of the "Good Neighbor." Specifically, it focuses on two oft-overlooked types of naval diplomacy the United States used to exercise influence in the South American nation of Peru: the employment of U.S. personnel as naval advisers to the Peruvian government, and the use of U.S. naval vessels as agents of public diplomacy on "goodwill" cruises and port visits in Peruvian waters. It argues that the United States …


Development Of Hydrogel Tracer Beads And Comparative Tracer Tests To Better Understand Contaminant Fate And Transport In Karst Systems, Amanda Laskoskie May 2013

Development Of Hydrogel Tracer Beads And Comparative Tracer Tests To Better Understand Contaminant Fate And Transport In Karst Systems, Amanda Laskoskie

Graduate Theses, Dissertations, and Problem Reports (ETD)

Karst aquifers can be highly susceptible to contamination due to a close connection to the land surface, lack of filtration through a soil zone, and rapid transmission along solutionally-enhanced flowpaths. These factors also allow for aquifer contamination by direct injection of immiscible organic compounds in the form of non-aqueous phase liquids (NAPLs). The fate and transport of NAPLs in karst aquifers is poorly understood. Tracer tests allow for qualitative characterization of hydraulic flow in the surface and subsurface, but their results may not be applicable to the movement of NAPL for which density plays a critical role. Particulate tracers have …
