Financial Literacy And Consumer Well-Being: Examining The Role Of Gender Role Ideology, Lorena Garcia Ramon

Theses and Dissertations

Financial literacy, or the ability to process economic information and make informed decisions about financial planning, wealth accumulation, debt, and pensions, has been linked to beneficial financial behaviors that support financial well-being. Despite these benefits, consumers tend to underperform in financial literacy tests with women generally faring worse than men. This dissertation draws from gender roles literature and Expectancy-Value Theory to examine how, why, and when traditional attitudes regarding societal gender roles (i.e., gender role ideology) hinder women’s financial literacy and willingness to acquire financial knowledge. Moreover, it examines how financial literacy and willingness to …

Infection And Transmission Determinants Of Flea-Borne Rickettsioses, Hanna J. Laukaitis

Graduate Theses and Dissertations (2019 - present)

The genus Rickettsia is comprised of Gram-negative, obligate intracellular bacteria that are spread by hematophagous arthropods. Elucidating the factors conferring rickettsial virulence has perplexed investigators for decades, complicated by the lack of efficient genetic tools necessary to uncover rickettsial- and vector-specific factors contributing to persistence. The advent of transposon mutagenesis has enabled the field to make vast developments in uncovering novel rickettsial mechanisms utilized in various host backgrounds. Thus, the aim of this study was to generate Rickettsia felis transposon mutants and characterize novel phenotypes associated with genetic disruption in an arthropod background. Distribution of rickettsiae is reliant on the …

The Role Of Microbiota On Campylobacter Jejuni Colonization And Growth Performance In Broiler Chickens, Ayidh Almansour

Graduate Theses and Dissertations

The successful poultry production at modern era comes from the vertical integratedindustrialization, which has fundamentally changed how animals have been living for millions of years. Antimicrobial growth promoters have been used to sustain the efficient industrialized animal production, driving antimicrobial overuse and resistance. Because of the increasing pressure from consumer’s concerns and government regulations, it is urgent to develop antimicrobial free alternatives as growth promoters in poultry production, but few effective antimicrobial alternatives are currently available. Campylobacter jejuni is one of the worldwide prevalent foodborne bacterial pathogens mainly transmitted from poultry. However, few mechanisms are available on why C. jejuni …

Comparing Collegiate Coaches’ And Players’ Perceptions Of The Coaches’ Multicultural Competence, Lee Arakawa

Dissertations

The coaching effectiveness model developed by Horn (2008) describes cultural context as a backdrop that forms beliefs, perceptions, and behaviors displayed by sport coaches. Sue et al.’s (1992) multicultural competencies model stresses the value of awareness, knowledge, and skills used in all service fields to strengthen cross-cultural relationships. Therefore, multicultural competence has been identified from these models as a critical component of effective sport coaching. Despite the growing importance of multicultural competencies expressed by, and for, sport coaches (Mesquita et al., 2011; Santos et al., 2010), there remains limited understanding of how coaches obtain and apply multiculturally competent behaviors and …

Endophyte-infected (Neotyphodium coenophialum) tall fescue, [Schedonorus arundinaceus (Shreb.)] produces ergot alkaloids. Condensed tannins could bind to ergot alkaloids and render them ineffective. The first objective was to improve the health of sheep offered endophyte-infected tall fescue by binding toxins in the rumen with condensed tannins. Non-toxic novel-endophyte infected tall fescue (NE) or toxic endophyte-infected tall fescue forage was harvested, baled at targeted moisture of 55%, wrapped within 8 hours of baling with 2 layers of net wrap and 20 layers of plastic, and ensiled for at least 60 days. Prior to feeding, forages were chopped and packed into plastic trash …

Dairy Breed, Grass-Birdsfoot Trefoil Mixture, And Pasture Nutrition Effects On Intake, Feed Efficiency, And Grazing Adaptation, Michael Greenland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dairy cattle have lower dry matter intake (DMI) on pastures thus leading to less weight gain and milk production than feedlot cows. This study was conducted to determine whether different dairy breeds are better adapted to lower or higher quality pastures as measured in DMI and feed efficiency. The eight treatments consisted of Jersey, Holstein, Holstein-Jersey crossbreds, and 3-breed crossbreds (Montbéliarde-Swedish Red-Holstein) heifers on grass monocultures and grass-BFT mixtures. We observed greater DMI on grass-BFT mixtures. Among breeds, Holstein had the greatest DMI, then the two crossbreds, and Jersey had the least. Feed efficiency was most favorable for Jersey, less …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Knowledge of both soil quality and contamination has become increasingly important with the growth of urban agriculture in Utah and the United States as whole. Land is also a common limiting factor in urban agriculture, so it is important to maximize yield and net returns. In order to meet these demands, three studies were conducted across key urban agriculture sites along the Wasatch Front: 1) an urban soil survey to assess soil contamination, 2) an urban soil survey to evaluate macronutrient and salinity levels, and 3) a nitrogen fertilizer management trial for dahlia (Dahlia pinnata), a cut flower …

Skeletal Muscle Growth Of Beef Cattle: Cattle Breed Types And Anabolic Implants, Caleb C. Reichhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two potential methods that can be used by the U.S. to help further improve environmental and economic sustainability of the beef industry are through the use anabolic implants, typically composed of the hormones estradiol and trenbolone acetate, and by crossbreeding Bos taurus and Bos indicus cattle. How anabolic implants operate to improve growth, and their resulting relationship with different cattle breed types have yet to be determined. However, crossbreeding these cattle breed types has been found to have a positive influence on economically important traits such as average daily gain and carcass characteristics. Therefore, we hypothesized that the different hormones …

Cuo Nanoparticles Solubility As Influenced By Soil Pore Water, Native Microorganisms, And Wheat Rhizosphere Chemistry In A Sand Matrix, Dakota Sparks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nanoparticles (NPs) are particles less than 100 nm (~4 millionths of an inch) in a direction. NPs, due to their small size, are used in a variety of products, such as silver (Ag) NPs as an antimicrobial in clothes. Copper Oxide (CuO) NPs are used in electronics as semiconductors and other fields as antimicrobials and purposefully or accidentally end up in the environment. Copper (Cu) is a necessary nutrient for plants, but at higher amounts is toxic to plants and beneficial soil microbes.

In order to understand how the CuO NPs interacts with plants, wheat seedlings were grown in sand …

Using Cytoplasmic Biopsies To Determine Bovine Oocyte Quality, Madison Lindsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Embryos resulting from assisted reproductive technologies, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), develop with lower efficiencies than embryos resulting from their in vivo counterparts. The reasons behind the developmental discrepancies remain largely unknown. Because the egg is the primary determinant of embryo developmental success, it is reasonable to consider inherent egg quality as a possible cause. The hypothesis for this project is that there are distinct mRNA transcript patterns, or molecular “fingerprints,” that distinguish high- versus low-quality eggs developing within the same environment. In this study, a small cytoplasmic biopsy was removed from 40 eggs …

Natural History And Development Of Melittobia Acasta On Megachile Rotunda , Alan R. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is one of the most economically important crops in North America. To produce alfalfa seed, a pollinator must release plant reproductive organs by applying pressure to keel petals. The alfalfa leafcutting bee, Megachile rotundata, is the primary commercial pollinator of alfalfa. U.S. bee managers struggle to maintain populations due to many mortality factors. One cause is attack from parasitoid wasps such as Melittobia acasta. Females can lay hundreds of eggs and have multiple generations, which can decimate bee stocks. Chapter Two investigates the life cycle and base temperature that allows development of M. acasta on bee hosts. …

Maternal Effects And Management Of Alfalfa Leafcutting Bees, Makenna May Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Most bees are solitary and important contributors to pollination of a variety of crops. Solitary bees do not live in colonies. Instead, females work individually to construct nests and provision nutrients for each offspring. However, solitary bees can be difficult to manage, especially on a large scale like honey bees, because of differences in how species provision for their offspring and construct nests. Variations in the timing of offspring development to adulthood even within species makes commercial management difficult. Variations in reproductive strategy, like how many offspring to make, how much provision to give each, and when to make them …

Evaluation Of Noninvasive Methods For Determining Pregnancy, Diet, Nutrition, And Stress Among Pronghorn Antelope: Implications For Population Monitoring, Cole Bleke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to increase our understanding of the influence of adult female pronghorn (Antilocapra americana) physiology on fawn summer survival. Pronghorn are a valued big game animal in Idaho, but are particularly sensitive to capture; therefore, we designed a noninvasive fecal sampling study to measure pregnancy (progesterone and estrogen), diet, nutrition (fecal nitrogen and DAPA), and stress (cortisol), during metabolically-demanding female life history stages (late gestation, early lactation, and breeding season). We also compared survey results between ground and aerial methods within mountain valley landscapes.

Pregnancy determination, via progesterone, is possible for pronghorn, but sample collection …

Comparing Fecal Dna Capture-Recapture Methods To Traditional Mark-Resight Methods For Estimating Abundance Of Mule Deer On Winter Ranges, Andi M. Stewart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Well-designed monitoring strategies are required to obtain accurate estimates of population abundance, which is important for evaluating conservation and management strategies. Obtaining abundance estimates using traditional survey methods, like aerial surveys, is not possible in all scenarios and can be expensive and risky. One survey method that has gained popularity in the last decade is fecal DNA-based capture-recapture (CMR). However, this method has not been evaluated on winter ranges or in snowy, winter conditions.

My first objective was to implement fecal DNA CMR to estimate abundance of mule deer in the Round Valley and Goodale winter survey areas in the …

Development Of Late-Heading Orchardgrass Germplasm, Megan Marie Getz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dactylis glomerata L., orchardgrass, is commonly grown with perennial forages such as alfalfa (Medicago sativa L.). However, commercial orchardgrass cultivars currently grown in the Intermountain West generally flower earlier than alfalfa. This results in a reduction in grass nutritional value if harvested to maximize the alfalfa yield, because the two species mature at different rates. Thus, there is a need to better understand the genetic basis of flowering time in orchardgrass and develop late-flowering populations. The objectives of this research were to evaluate the ability to identify and use molecular markers to identify and select late-heading orchardgrass; and to …
