But Does It Work? The Impact Of Social Media Use On Interpretive Outcomes And Place Attachments At San Francisco Bay Area Parks, Eric Knackmuhs
Electronic Theses and Dissertations
Many parks are now using social media sites to connect with visitors but little is known about how effective these efforts have been. This study examined the influence of social media use on interpretive outcomes and place attachment. Visitors to four parks in the San Francisco Bay Area were surveyed twice, once as they exited the park (n = 529) and a second time via email (n = 216) six to ten weeks after visiting. In both surveys, respondents were asked how they use social media to experience parks and to what extent they experienced interpretive outcomes (intellectual and emotional …

Bobcats Do Not Exhibit Rub Response Despite Presence At Hair Collection Stations, Chirstopher E. Comer, Symmank M. E., James C. Kroll
Bobcats Do Not Exhibit Rub Response Despite Presence At Hair Collection Stations, Chirstopher E. Comer, Symmank M. E., James C. Kroll
Faculty Publications
We evaluated the detection rate for hair snare sampling for bobcats (Lynx rufus) using colocated hair snares and infrared-triggered cameras at 20 locations on private property in eastern Texas. Hair snares and cameras were placed together at survey stations that included both visual and olfactory attractants. In 1,680 trap-nights we photographically documented 15 visits by bobcats but collected only one bobcat hair sample. Our observations suggested limited rubbing behavior by bobcats at hair snares despite presence at hair collection stations. The explanation for this behavior remains unclear but is consistent with observations of low and variable hair trap …

Many aspects of the Kenyan life were found to contribute to their efficiency and success. Analyzing Kenyan aspects of environment, altitude, society, diet, transportation, motives, and training may reveal possible ways American runners can improve their running.
The Effects Of Physical Education Credit Producing Activities On High School Students, Jonathan Denton
The Effects Of Physical Education Credit Producing Activities On High School Students, Jonathan Denton
Undergraduate Research Conference
The original intent for this project was to see what summative information could be drawn using the FITNESSGRAM. Researchers wanted to relate the FITNESSGRAM to variables like academic performance, amount of physical education, and the student’s general idea of physical education. Over the past few years, researchers have found that students with a higher score on the FITNESSGRAM have a higher academic score on the T.A.K.S., better attendance, and less behavioral problems. Also, researchers were interested in determining if a participant’s satisfaction level of the physical education experience had any impact on the FITNESSGRAM variables. This descriptive research was designed …

Choreographic Design And Process Of Dance, Kathleen Higgins
Undergraduate Research Conference
When I began the choreographic process, I was inspired by all of the emotions one might feel at a dance audition. However, with much though and manipulation of my original movement, I realized that the body image a dancer has of herself, and the body image for which she is continuously striving, was the underlying message that I wanted my choreography to communicate.

Analysis Of Critical Amino Acid Residues In Unc-45 Necessary For Its Interaction With Myosin Using Site-Directed Mutagenesis, Amanda H. Nolan
Undergraduate Research Conference
UNC-45 is an important protein for muscle contraction and heart formation. The UNC-45 protein is a chaperone for the myosin heavy chain head, and UNC-45 only binds to the UCS domain of the myosin head. In our research for the interaction of myosin and UNC-45. The mutation was accomplished using the multiple sequence alignment method and site-directed mutagenesis. The mutations were generated in UNC-45 of Mus musculus (mouse), and the specific amino acids that were mutated were: L741A and L860F. The mutant proteins were sequenced and over-expressed for analysis.
Texas Black Bears, Alexandria Bryant
Texas Black Bears, Alexandria Bryant
Undergraduate Research Conference
One way to promote conservation efforts in an area is to bring awareness of the connections our society has with the animal that is under threat. Black Bears were once abundant throughout Texas, but through hunting and habitat loss, the bears had been eliminated from Texas by the 1950s. The placing of the Louisiana subspecies as threatened under The Federal Endangered Species Act in 1922 allowed populations to recover in Louisiana, and there have been several sightings in East Texas since. The face of Texas has been forever altered byt the presence of black bears. From the forests of East …

Measurement Of Particle Size Distribution In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Faculty Publications
The majority of the research in animal buildings has been on measured concentrations of contaminants that the workers and animals are exposed to; emission measurements have only gained attention in recent years due to potential federal regulations on air quality emissions from animal feeding operations (AFOs). The contribution of AFOs to ambient PM10 and PM2.5 entails reliable measurement of particle size distribution. The objective of this study was to measure and compare the size distribution of particulate matter (PM) at multiple locations inside and at the exhausts of a wean‐to‐finish commercial swine building. The particle size distribution was measured by …

Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Faculty Publications
Pollutants, especially dust, are rarely uniformly distributed within ventilated air spaces due to non‐uniform flow fields, particle inertia, gravitational settling, and diffusion. Thus, selecting suitable sampling locations for representative sampling is a challenge. The objective of this study was to determine the spatial and temporal distributions of dust and ammonia concentrations(NH3) in a swine building. Results of this study are useful in the design of sampling strategies that require limited sampling locations and in studying pollutant transport. This study was conducted in a commercial swine building in Illinois. The total suspended particulate (TSP) matter and ammonia concentrations were measured at …

Cooper’S Hawk Nest Site Characteristics In The Pineywoods Region, Richard R. Schaefer, D. Craig Rudolph, Josh B. Pierce, Jesse F. Fagan
Faculty Publications
Early accounts describe the Cooper’s Hawk (Accipiter cooperi) as a species in decline in much of North America during the early twentieth century (Bent 1937), particularly when in close proximity to humans (Eaton 1914). This decreasing population trend continued to be recognized later in the century in both Texas (Oberholser 1974) and Louisiana (Lowery 1974). Shooting and trapping during the first half of the 1900s, and pesticide use (especially DDT) after World War II are suggested as primary causes of the decline (Henny and Wight 1972, Bednarz et al. 1990). The Migratory Bird Treaty Act of 1972 and the ban …

A Mixed-Effects Height-Diameter Model For Individual Loblolly And Slash Pine Trees In East Texas, Dean W. Coble, Young Jin Lee
Faculty Publications
A new mixed-effects model was developed that predicts individual-tree total height for loblolly (Pinus taeda) and slash pine (Pinus elliottii) as a function of individual-tree diameter (in.), dominant height (ft), quadratic mean diameter (in.), and maximum stand diameter (in.). Data from 119,983 loblolly pine and 42,697 slash pine height– diameter observations collected on 185 loblolly pine and 84 slash pine permanent plots located in plantations throughout East Texas were used for model fitting. This new model is an improvement over earlier models fit with ordinary least squares, in that it can be calibrated to a new stand with observed height– …

Spread Of Plague Among Black-Tailed Prairie Dogs Is Associated With Colony Spatial Characteristics, Christopher Frey, Tammi L. Johnson, Jack Cully Jr., Sharon K. Collinge, Chris Ray, Brett Sandercock
Faculty Publications
Sylvatic plague (Yersinia pestis) is an exotic pathogen that is highly virulent in black-tailed prairie dogs (Cynomys ludovicianus) and causes widespread colony losses and individual mortality rates >95%. We investigated colony spatial characteristics that may influence inter-colony transmission of plague at 3 prairie dog colony complexes in the Great Plains. The 4 spatial characteristics we considered include: colony size, Euclidean distance to nearest neighboring colony, colony proximity index, and distance to nearest drainage (dispersal) corridor. We used multi-state mark–recapture models to determine the relationship between these colony characteristics and probability of plague transmission among prairie dog colonies. Annual mapping of …

A Gis Tool For Plant Spatial Pattern Analysis, Yanli Zhang, Nathan Woodward, Daniel Unger, I-Kuai Hung, Brian P. Oswald, Kenneth W. Farrish
Faculty Publications
A GIS program, ArcPlantPattern, was developed with Visual Basic .NET and ArcObjects as an ArcGIS extension to assist the investigation of plant distribution patterns (species composition as occurrence probability and spacing as distances among species) and to design planting plan maps for patch planting. ArcPlantPattern is the first software of its kind. It can be used for arid and semiarid lands reclamation, burned area rehabilitation, or designing landscapes with a required plant community distribution. ArcPlantPattern may also be applicable to other spatial point pattern analysis, such as geology, geography and wildlife habitat.
