Study Of A Contemporary Diet In One Household In The Yucatan, Ericka K. Hardin
Study Of A Contemporary Diet In One Household In The Yucatan, Ericka K. Hardin
Mahurin Honors College Capstone Experience/Thesis Projects
The history of the Yucatan has played a major role in the development of the food system of the area and the nutritional status of the population. Originating from an agricultural based diet, which forms the foundation of the traditional Yucatan diet, there has been a recent shift away from whole and natural foods to a more processed and convenient food supply due to the influx of American products and culture. Coinciding with the influx of these unhealthy foods, there has also been a rise in the health problems of the Mexican population such as heart disease and diabetes, both …
Quality Change And Thermal Inactivation Of Escherichia Coli O157:H7 In Non-Intact Beef And Veal Patties By Double Pan-Broiling, Kawang Li
Mahurin Honors College Capstone Experience/Thesis Projects
Escherichia coli O157:H7 (ECOH) may translocate from meat surfaces to internal tissues during grinding processes. This study evaluated the inactivation of ECOH in ground beef and veal by cooking to various internal temperatures (55°C, 62.5°C, 71.1°C, and 76°C). Grounded beef/veal were inoculated with 6 log ECOH and prepared into patties, stored aerobically (4°C, 4 -days) before double-pan-broiling to the internal temperatures mentioned above with a three-minute rest. Samples’ color were monitored, which changed significantly during storage and cooking. Pathogen concentration was measured by plating the homogenized sample on TSA and McConkey agar. The pathogen population was below detectable limit when …
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Mahurin Honors College Capstone Experience/Thesis Projects
BACKGROUND: Motor control, learning, and development need to be considered by any coach working with youth athletes. When coaches fail to consider these areas, they may be more likely to create practice plans, which omit the innate physiological and psychological differences between youth and adult participants, lessen the development of sport-specific skills, and may create less enjoyable sporting experiences for young players. PURPOSE: The aims of this literature review were to explore recent scientific literature linking motor behavior/development to application in youth basketball, identify major themes, and summarize these concepts in a manner useful to coaches in this environment. METHODS: …

Intergenerational Service-Learning With Exercise Science Students, Mckinze R. Vowels
Mahurin Honors College Capstone Experience/Thesis Projects
Exercise science professionals often work with older adults to help maintain function and independence. Ageism may begin during undergraduate training, as most have not interacted with older adults. Intergenerational service-learning (ISL) may be a useful pedagogy to facilitate interactions with older adults. PURPOSE: To determine if exercise science students’ knowledge of older adults and ageism are significantly improved by incorporating ISL into an exercise science course. METHODS: Students (n =10) enrolled in Exercise and Aging and from two additional exercise science courses (n = 17) completed pre and post assessments of attitudes towards and knowledge of older adults. Students implemented …

Trophic Dynamic Interactions In A Temperate Karst River, Elizabeth Malloy
Masters Theses & Specialist Projects
Surface streams in karst landscapes are often characterized by high nutrient levels due to incomplete filtration through series of innumerable, below-ground conduits. Seasonal growth of the filamentous alga, Cladophora, is typically associated with nutrient-rich waters. This research compared macroinvertebrate food web structure between riverine reaches with contrasting underlying karst topography, nutrient levels, and Cladophora cover during summer 2012 and autumn 2013. Recent work in these reaches found a high correlation between Cladophora cover and nutrient content, particularly nitrate. Four questions were addressed during this study: 1. Do longitudinal trends in algal and consumer δ13C values relate to decreased DIC availability …

The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris
International Journal of Exercise Science
International Journal of Exercise Science 7(4) : 339-345, 2014. Inclined treadmill walking is a commonly performed activity to increase cardiovascular health. Handrail support on a treadmill provides an individual the opportunity to change their posture with respect to the walking surface. Differences in metabolic cost during inclined walking due to postural changes with handrail use are unknown. To test the hypothesis that metabolic cost will differ depending on how handrail support is used, respiratory gas analysis was performed during inclined walking in 13 healthy subjects. Energy expenditure was quantified while each subject walked in four conditions: 5% incline unsupported, 10% …

Landscape Genetics Of The Endangered California Tiger Salamander (Ambystoma Californiense) In The Los Vaqueros Watershed, Ryan Neal Vincent
Landscape Genetics Of The Endangered California Tiger Salamander (Ambystoma Californiense) In The Los Vaqueros Watershed, Ryan Neal Vincent
Mahurin Honors College Capstone Experience/Thesis Projects
Genetic diversity is essential for maintaining healthy biological systems, and dispersal-mediated gene flow increases genetic diversity by introducing new alleles to a gene pool. Populations that frequently experience gene flow will show characteristic similarities in allele frequencies. Measuring genetic diversity among many populations across a landscape has proven to be a powerful approach for assessing the ways that habitat discontinuities may affect patterns of gene flow, and in turn, influence allele frequencies and population dynamics. This study examines the landscape-level population genetic structure of the California tiger salamander, Ambystoma californiense, within the Los Vaqueros Watershed of Contra Costa County, …

Functional And Expression Analysis Of A Novel Basement Membrane Degrader In Drosophila Melanogaster, Christopher J. Fields
Mahurin Honors College Capstone Experience/Thesis Projects
SNUTS is a protein coding gene present in Drosophila melanogaster whose product contains conserved domains that are present in a range of eukaryotic organisms. The SNUTS protein is made up of four domains, two Sterile Alpha Motif (SAM) domain, and two Plant Homeodomains (PHD). The biological function of SNUTS or the various domains is largely unknown. One study demonstrated that SNUTS was important for proper development of the stem cell niche. In the present study data from both overexpression and downregulation of Snuts and the resulting phenotypes are presented. Data supporting potential mechanisms resulting in the phenotype are also presented. …
Beyond Sustainability: A New Conceptual Model, Molly Kerby, Gayle Mallinger
Beyond Sustainability: A New Conceptual Model, Molly Kerby, Gayle Mallinger
Faculty Publications
Over the last few decades, the notion of sustainability has become an interdisciplinary buzz word. Sustainability has been an integrative concept that includes three constructs or pillars: a) social; b) economic; and c) ecological. Until recently, theoretical approaches based on the three pillars approach have operated in silos rather than exploring the interconnectedness of the constructs. Few models have moved beyond the idea that logical relations exist among the constructs (social, economic, and ecological) to consider factors external to communities, nor have they examined the internal socio-economic factors that influence positive outcomes. While this conceptualization has raised awareness about the …

Vo2 Reserve Vs. Heart Rate Reserve During Moderate Intensity Treadmill Exercise, Tanner J. Solheim, Brad G. Keller, Charles J. Fountaine
Vo2 Reserve Vs. Heart Rate Reserve During Moderate Intensity Treadmill Exercise, Tanner J. Solheim, Brad G. Keller, Charles J. Fountaine
International Journal of Exercise Science
International Journal of Exercise Science 7(4) : 311-317, 2014. VO2 and heart rate (HR) are widely used when determining appropriate training intensities for clinical, healthy, and athletic populations. It has been shown that if the % reserve (%R) is used, rather than % of max, HR and VO2 can be used interchangeably to accurately prescribe exercise intensities. Thus, heart rate reserve (HRR) can be prescribed if VO2 reserve (VO2R) is known. Therefore, the purpose of this study was to compare VO2 R and HRR during moderate intensity exercise (50%R). Physically active college students …

Efficacy Of An Electronic Scarecrow On 4 Mammalian Crop-Raiders In Limpopo Province, South Africa, Merrie Renee Richardson
Efficacy Of An Electronic Scarecrow On 4 Mammalian Crop-Raiders In Limpopo Province, South Africa, Merrie Renee Richardson
Masters Theses & Specialist Projects
In South Africa, 2 primate species, Chacma baboons (Papio ursinus) and vervet monkeys (Chlorocebus pygerythrus), and 2 nocturnal mammals, Cape porcupine (Hystrix africaeaustralis) and bushbuck (Tragelaphus scriptus), are among many species of crop raiders. Currently, cost-effective, non-lethal solutions are lacking. From June through December 2012, I installed novel electronic scarecrows on two commercial citrus orchards and a private reserve and used video-recording remote cameras to assess cropraiders’ reactions to them in Limpopo Province, South Africa. I used focal animal sampling data from treatment and control group animals to examine differences in activity …
