The Role Of Appearance In Perceptions Of Personal Trainers 2013., Patrick R. Boerner
The Role Of Appearance In Perceptions Of Personal Trainers 2013., Patrick R. Boerner
Master's Theses
The field of personal training in the United States is believed to have begun in the late 1970‟s and the early 1980‟s (Brooks, 2004). Today, personal training is a healthy profession that, according to the United States Department of Labor and the Bureau of Labor Statistics (2012), is expected to grow 24% (60,400 jobs) between 2010 and 2020. In comparison, the Bureau of Labor Statistics (2012) predicts the average growth rate for all occupations within the U.S. to be only 14% during the same ten-year span. Rapid growth within the field of personal training has brought an increased scrutiny on …
Cost-Benefit Analysis Of Farmer Training In Ghanaian Cocoa Farming, Michael Norton
Cost-Benefit Analysis Of Farmer Training In Ghanaian Cocoa Farming, Michael Norton
Agricultural Economics and Agribusiness Undergraduate Honors Theses
While billions of dollars flow into low-income countries each year to help alleviate poverty, assessing the effectiveness of these dollars is a challenging task. The literature is rich in studies that measure the benefits of rural development programs. However, many of these studies lack a temporal dimension because they measure cost and benefits for only capital investments and for only a single, static year, while not accounting for skill enhancement. By only measuring net producer benefits during the life of the development program, the cost-benefit analyses (CBA) may not truly capture the full net benefits of a given program. In …
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Capstone Collection
On June 5, 2009 a 42-‐km2 area of coral reef situated in the Alif Dhaalu (South Ari) atoll of the Republic of Maldives was designated the South Ari Atoll Marine Protected Area (S.A. MPA) due to a globally significant whale shark aggregation site. The whale shark is notorious for its gargantuan size and docile nature, which has led to a burgeoning tourist industry that gives people the opportunity to swim with the gentle giants in tropical sites such as the Maldives. The S.A. MPA receives tens of thousands of visitors a year that engage in whale shark excursions, however, there …

Effects Of Ergot Alkaloids And Bovine Bodily Fluids On Cytochrome P450 Activity, Nicholas Scott Ezell
Effects Of Ergot Alkaloids And Bovine Bodily Fluids On Cytochrome P450 Activity, Nicholas Scott Ezell
Graduate Theses and Dissertations
This thesis evaluates the PromegaTM P450-Glo assay (PromegaTM V9800) as a tool for quantifying ergot alkaloid concentration. Current techniques used for detection of ergot alkaloids are slow and expensive, do not detect all ergot alkaloids, or are not effective on bovine bodily fluids. The first study was conducted to determine effects of commercial ergot alkaloids (n = 6; 0 - 400 μM) on the PromegaTM P450-Glo assay. Cytochrome P450 (CYP450) activity in assay had a differential response to each ergot alkaloid and concentration. As concentrations of ergotamine, dihydroergotamine, ergocornine, and ergocryptine increased CYP450 activity was inhibited (P …

More than 4%, 26%, and 70% of children with protein malnutrition live in Latin America/the Caribbean, Africa, and Asia, respectively. The objective of this research was to develop a novel snack made with millet, black eye bean (from Niger Republic), and rice flour fortified with soybean meal protein using extrusion technology. Proximate analysis of the four flours was carried out to determine their chemical composition. Central composite design (CCD) was used to obtain best extrusion conditions to develop a protein-enriched …
Genetic Structure Of The Copperhead (Viperidae: Agkistrodon Contortrix Mokasen) At Its Most Northern Distribution, Brenna Aaren Levine
Genetic Structure Of The Copperhead (Viperidae: Agkistrodon Contortrix Mokasen) At Its Most Northern Distribution, Brenna Aaren Levine
Graduate Theses and Dissertations
The focus of molecular studies in North American pitvipers has been on species that warrant conservation concern, such as Timber (Crotalus horridus) and Massasauga rattlesnakes (Sistrurus catenatus). Scant effort has been directed towards the molecular ecology of the Copperhead (Agkistrodon contortrix), other than to evaluate male reproduction in a laboratory setting and phylogenetic history. Thus, employing DNA-based molecular techniques to study the natural history of A. contortrix will broaden our knowledge of molecular ecology in North American pitvipers, and particularly in a non-threatened species that can serve as a surrogate for threatened and endangered …
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Graduate Theses and Dissertations
The Center for Disease Control and Prevention (CDC) suggests that adolescents and children, both male and female, are failing to meet the daily fruit and vegetable consumption requirements (Kim et al., 2011; Upton et al., 2012; Harris et al., 2012). Other studies have shown that with increased exposure and availability of produce, students (K-5) tend to consume more fruits and vegetables (Cullen et al., 2009; Evans et al., 2012). The purpose of this study is to identify whether Northwest Arkansas eleventh grade high school students possess experience and knowledge of local produce and agriculture. Out of 1054 students enrolled at …
Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr
Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr
Graduate Theses and Dissertations
Six experiments were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that canola meal can be used in isocaloric diets as a partial replacement for Soybean meal.
Experiment 2 assessed broiler performance and carcass yields when using various levels of canola meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental …
A New Commons: Considering Community-Based Co-Management For Sustainable Fisheries, Charlotte L. Dohrn
A New Commons: Considering Community-Based Co-Management For Sustainable Fisheries, Charlotte L. Dohrn
Pomona Senior Theses
Commercial fisheries on the West Coast are traditionally managed under large-scale management and conservation plans implemented by state and federal agencies. This scale of management can present obstacles for fishing communities. This thesis examines emerging cases of attempts to define and implement sustainable management of commercial fisheries under a community-based co-management model. In Port Orford, Sitka, San Diego and Santa Barbara, preliminary community-based co-management models are enabling fishing communities to pursue social sustainability through preserving access, participating in local science, and direct marketing for fish products. These communities are actively reshaping traditional models of conceptualizing and managing common-pool resources like …
Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut
Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut
UNLV Theses, Dissertations, Professional Papers, and Capstones
As a fundamental component of the developing discipline of conservation biogeography, broadscale analyses of biotic assembly and disassembly across multiple temporal and spatial scales provide an enhanced understanding of how geologic transformations and climate oscillations have shaped extant patterns of biodiversity. As with any scientific field, there are limitations in the case of biogeographic historical reconstructions. Historical reconstructions are only as robust as the theoretical underpinnings of the methods of reconstruction (including data collection, quality, analysis, and interpretation). Nevertheless, historical reconstructions of species distributions can help inform our understanding of how species respond to environmental change.

Predicting Chest Press Strength From A 4rm Triceps Brachii Exercise In Trained Women, Krystina Nadia Moschella
UNLV Theses, Dissertations, Professional Papers, and Capstones
Determining maximal strength is important when developing a resistance exercise program for trained athletes. The most frequent strength procedure used to evaluate maximum strength is the 1RM test. However, risk of injury from a 1RM test increases for the athletes, therefore a 4RM test is used in the following study. The purpose of the study is to test whether there is a linear relationship between the bench press and the triceps rope extension exercise. A secondary purpose is the development of a prediction equation for the purpose of prescribing bench press exercise loads from triceps brachii loads using a 4RM …

Genetic Analysis Of The Promoter Region Of The Serotonin Receptor 5ht2b And Its Contribution To Pulmonary Hypertension Syndrome In Broiler-Type Chickens, Khaloud Awada Alzahrani
Graduate Theses and Dissertations
Pulmonary Arterial Hypertension (PAH) is a sever disorder characterized by high pulmonary artery pressure and pulmonary vascular resistance along with specific histological changes. Idiopathic PAH is a human disease of unknown origin that showed common characteristics to PHS/ascites in chicken. PHS/ascites is a condition found in broilers causing right ventricular hypertrophy, valvular insufficiency, increased venous pressure, variable liver changes, accumulation of fluids in the abdominal cavity, and finally lung and heart failure. Currently, there is no acceptable animal model for human PAH. Our group has been validating the chicken as the medical animal model for human PAH, thus we have …
The Democratic Landscape: Envisioning Democracy Through Aldo Leopold's Land Ethic, Stacey L. Matrazzo
The Democratic Landscape: Envisioning Democracy Through Aldo Leopold's Land Ethic, Stacey L. Matrazzo
Master of Liberal Studies Theses
Since its founding, nature and nature-ownership have been central to American democracy, with property ownership remaining a fundamental part of its citizens' idea of liberty and freedom. Although initially constrained by common law principles, private property rights have varied over the centuries and have largely ignored the land's natural features. Landownership today tends to equate more with individual power than public responsibility. As a result of individualistic actions that have degraded the landscape and neglected the interdependence of humans with the greater biotic community, the divide between humans and nature has grown. In his groundbreaking essay, "The Land Ethic," Aldo …

Tactile Behavior In A Group Of Captive Rough-Toothed Dolphins As A Function Of Opportunities To Play With Objects, Kelly Ann Caffery
Tactile Behavior In A Group Of Captive Rough-Toothed Dolphins As A Function Of Opportunities To Play With Objects, Kelly Ann Caffery
Dissertations
Cetaceans live in complex physical and social environments that are frequently changing. In contrast, the captive environment for marine mammals is often lacking in stimulation. As a result, enrichment is often used to increase species-typical behaviors and enhance the well-being of the animals. The purpose of this study was to compare the effects of enrichment objects on the social behavior of a group of seven captive rough-toothed dolphins (Steno bredanensis). Observations of this species in the wild suggest it may have a particular affinity for tactile and object play behaviors. Therefore, these behavior categories were a primary focus …
Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens
Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens
Dissertations
Socio-ecological theorists tie primate social structure diversity to variations in habitats within which primate species reside. This premise permits laboratory researchers to investigate specific factors that influence or relate to social structure formation and maintenance. The focus of the current investigation was three fold. We first aimed to determine the relationships between traditional and non-traditional behavioral measures of dominance, then evidence for dominance hierarchy formation was examined, and various hypotheses were tested to discern if adjustments in the foraging context altered social behaviors in Garnett’s bushbaby (Otolemur garnettii). It was determined that animals likely to displace conspecifics were …
Determinants Of Food Insecurity Among Vulnerable White And Latino Households: Contextualizing The Impact Of Sociodemographic And Household-Level Factors, Alexandra Lund
Master's Theses
Household-level characteristics have been shown to be associated with food insecurity but studies among vulnerable populations are sparse. A food security assessment was developed to determine food security and collect sociodemographic and household level data across San Luis Obispo County. The assessments were administered to vulnerable groups through interviews at multiple sites across the County. Three household characteristics (marital status, number of children in the household and number of workers in the household) were examined in this analysis. A total of 808 surveys were collected, 69% in English and 31% in Spanish. Through ethnicity-stratified sequentially adjusted logistic regression models, the …
Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson
Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable past the point of donor separation.
This paper proposes the …

A Need For Green: An Approach For Motivating Environmentally Sustainable Practices At The University Of Rhode Island, Alyssa Mason, Mary Vidal
Senior Honors Projects
“Never underestimate the power of a few committed people to change the world. Indeed, it is the only thing that ever has." -Margaret Meade
Colin Beavan’s No Impact Man details his yearlong experiment to live without creating any environmental impact. As sophomores we were inspired by Beavan’s journey but also skeptical of living a completely no-impact lifestyle as college-students. Although we were motivated to try to live sustainably, our efforts were dormant until our junior year. That year we decided that we would attempt to live up to the standards set forth by Beavan--understanding that some practices would be harder …

A Mixed Methods Case Study: Understanding The Experience Of Nebraska 4-H Participants Relative To Their Transition And Adaptation To College, Jill Walahoski
Department of Educational Administration: Dissertations, Theses, and Student Research
This mixed methods case study was designed to assess the preparedness of former Nebraska 4-H participants to successfully transition and adjust to college. The study also sought to understand the way that students’ experiences in Nebraska 4-H may have influenced their readiness to transition to college. The initial quantitative stage of this case study administered the Student Adaptation to College Questionnaire to former 4-H participants who were recent high school graduates. Latter qualitative stages included interviews with staff regarding the practices and strategies they employed related to preparing young people for college and interviews with former 4-H participants selected from …
Measuring The Energy Required To Dry Rice In Commercial Rice Dryers, Maria Alejandra Billiris
Measuring The Energy Required To Dry Rice In Commercial Rice Dryers, Maria Alejandra Billiris
Graduate Theses and Dissertations
The objective of this research was to quantify and assess the energy use and efficiency of commercial cross-flow dryers when drying rice using a range of drying and ambient conditions. First, equations that predict the theoretical energy required to dry rice from any given initial moisture content to a desired final moisture content were developed for several rice cultivars using a semi-theoretical approach to obtain a basis for comparison to calculate energy efficiency. Theoretical energy requirements, expressed as the energy required per unit mass of water removed, increased exponentially as initial moisture content decreased. Additionally, medium-grains required more energy to …
Accessing Learning In The Adult Zebrafish With A Novel Associative Learning Task, David Joseph Jouandot Ii
Accessing Learning In The Adult Zebrafish With A Novel Associative Learning Task, David Joseph Jouandot Ii
Dissertations
The zebrafish (Danio rerio) is accepted in the developmental and genomic communities as a model organism. However, the capacity for the zebrafish as a behavioral model has yet to be fully acknowledged. The research presented provides evidence validating the novel task, aids in gaining a better understanding of the learning processes, and identifies individual differences. The novel associative learning task differs from any present well established behavioral model and lends itself to future development. The task provides the zebrafish community with a high output behavioral task which is readily replicated and allows one researcher to test between eight …
