Magnetic Resonance Imaging, Arthrography, And Ultrasound In Diagnosing Rotator Cuff Tears: An Evaluation Of Agreement, Andrea Solsona

Legacy ETDs

Eleven patients who had a clinical suspicion of a rotator cuff tear were referred for a magnetic resonance imaging exam, an arthrographic exam or both. Additionally, all patients received a diagnostic ultrasound exam. The results of the imaging studies were compared to surgical or clinical diagnosis. Arthrography had 100% positive predictive value (PPV), negative predictive value (NPV), accuracy, specificity, and sensitivity. Magnetic resonance imaging had 100% PPV, 60% NPV, 78% accuracy, 100% specificity, and 67% sensitivity. Ultrasound had 80% PPV, 50% NPV, 64% accuracy, 75% specificity, and 57% sensitivity. Based on these results, taking into consideration the national average costs …

Genetic Variation Within And Among Populations Of Florida Burrowing Owls (Athene Cunicularia Floridana), Wendy T. Denton

Legacy ETDs

This study employed DNA Polymerase Chain Reaction (PGR) and Single-Stranded Conformation Polymorphisms (SSCP) on a mitochondrial control region target to assess population structure and possible gene flow in the Florida Burrowing Owl (Athene cunicularia floridana), a Florida Species of Special Concern. Although widespread in Florida, Burrowing Owls occur at low densities in semi-isolated populations that are susceptible to extirpation from human development and the demographic consequences of small population size. To better manage these populations, there is a need for data on the population genetic structure of the Florida Burrowing Owl. Therefore, I acquired DNA from Burrowing Owls …

The Effects Of Aerobics And Walking On Social Physique Anxiety And Self-Esteem Of Female College Students, Jessica L. Lloyd

Legacy ETDs

The purpose of this investigation was to explore the effectiveness of walking and aerobics as a way of modifying body image apprehension and self-esteem of female college students. Participants from this study comprised 88 (25 African Americans and 63 Caucasians) students from a Southeastern university. The participants were administered the 9-item Social Physique Anxiety Scale (SPAS) (Martin, Rejeski, Leary, McAuley, & Bane, 1997) and the Rosenberg Self-Esteem Scale (RSES) (Rosenberg, 1979). Body composition, body weight, body height, and body mass index (BMI) were also evaluated. The participants performed in a 9-week walking or aerobics physical activity class. At the completion …

The Effects Of A Goal Setting Intervention And Dispositional Optimism/Pessimism On Selected Golf Skills: A Qualitative Design, Matthew James Wilson

Legacy ETDs

The purpose of this study was to examine the effects of a goal setting intervention on selected golf skills over the course of a competitive golf season. A secondary purpose of this study was to investigate a comparison of optimism and pessimism in relationship to goal attainment. Subjects (n=7) were elite golfers from a university men's golf team. A two-month goal setting intervention was implemented consisting of the individual golfers selecting three golf skills from five separate categories (fairways in regulation, greens in regulation, total putts per round, up and downs conversion rate, and putts per green in regulation) to …

Spiroplasma Diversity In Two Tabanid Flies And In Vivo Interactions Of Spiroplasma And Entomoplasma, Latonya T. Brown-Derrick

Legacy ETDs

Chrysops vittatus, a small deer fly, and Tabanus atratus, a horse fly, were captured concurrently in Bulloch County, Georgia during June through September of 1989-1997 Cultures were made from adult females, and the frequency and diversity of spiroplasma carriage were determined by deformation and endpoint testing.

Of the 90 Chrysops vittatus processed, 23 (25 .6%) carried spiroplasmas. The most prevalent spiroplasmas were representatives of group Vlll (20/23): strain B1357 (7/23); Spiroplasma syrphidicola (5/23); S. chrysopicola (4/23); strain TAAS-1 (4/23). Groups XVIII and XXXV were represented by S. Htorale (2/23) and strain B2649 (1/23), respectively.

Evaluation Of Coverboards For Sampling Salamanders In South Georgia, Charles Michael Houze Jr.

Legacy ETDs

Salamanders are important components of many forested communities. However, their fossorial habits and seasonality often make them difficult to sample. The use of artificial coverboards (coverboards) is a relatively new and little-studied technique for monitoring the terrestrial activity of salamanders Coverboards are designed to simulate fallen tree limbs and logs, and to provide a moist refuge for forest salamanders. Despite several studies, questions remain concerning the value of coverboards. Therefore, I conducted an experiment in 1996-1997 to determine whether coverboards are as effective for sampling salamanders as searching natural cover objects such as logs and branches. Using a paired design, …
