A Multi-Component School-Based Intervention Aimed At Increasing Vegetable Preference And Intake Among Elementary-Aged Children, Elizabeth Strasser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study aimed to implement and assess a school-based multi-component intervention aimed at increasing elementary school-aged children's knowledge of, preference for, and intake of vegetables. The multi-component intervention included lunchroom exposure, nutrition curriculum in the classroom, after school program vegetable curriculum, family friendly nutrition newsletter, vegetable fair and parent cooking class. Lunchtime vegetable consumption was assessed by direct observation. Changes in preference, attitude, and knowledge were assessed using a pre- and post-intervention survey.

The multi-component intervention was implemented at Canyon Elementary during the 2008-2009 school year. Classroom teachers provided 20 minutes of nutrition education to students in grades one through …

Fat Taste Transduction In Mouse Taste Cells: The Role Of Transient Receptor Potential Channel Type M5, Pin Liu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A number of studies have demonstrated the ability of free fatty acids to activate taste cells and elicit behavioral responses consistent with there being a taste of fat. Here I show for the first time that long chain unsaturated free fatty acid, linoleic acid, depolarizes taste cells and elicits a robust intracellular calcium rise via the activation of transient receptor potential channel type M5. The linoleic acid-induced responses depend on G protein-phospholipase C pathway indicative of the involvement of G protein-coupled receptors in the transduction of fatty acids. Mice lacking transient receptor potential channel type M5 exhibit no preference for …

The Effects Of Teaching Prefix Meaning And A Strategy To Derive Word Meaning On A Prefix Vocabulary Test And Sentence Comprehension Test For Middle School Students With Learning Disabilities, Shannon K. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous researchers have concluded that there is a need for determining how vocabulary instruction effects vocabulary comprehension and reading comprehension for young learners. Researchers have implemented morphemic strategies in various studies to identify effective methods for vocabulary instruction. In the present study, four prefixes were taught to students with disabilities to extend vocabulary research by using a morphological approach with a focus on prefix instruction. In addition students were taught how to combine the meaning of a prefix to the meaning of a root word. Data patterns indicate an increase in students' ability to provide definitions for prefixed words while …

Maporal Hantavirus Β-Integrin Utilization And Sensitivity To Favipiravir, Kristin K. Buys

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hantaviruses are members of the Bunyaviridae family of viruses. Pathogenic hantaviruses are the etiologic agents of hemorrhagic fever with renal syndrome (HFRS), a disease principally endemic in the Old World, and hantavirus pulmonary syndrome (HPS), a disease primarily restricted to the Americas. Maporal virus (MPRLV), a recently isolated hantavirus, has been found to cause disease in hamsters that resembles HPS in humans. However, the virus has not been linked to human cases of HPS. Considerable evidence suggests that β-integrin usage mediating infection may serve to distinguish hantaviruses pathogenic to humans from nonpathogenic, but this receptor usage pattern information is not …

Dietary Milk Fat Globule Membrane Reduces The Incidence Of Aberrant Crypt Foci In Fischer-344 Rats And Provides Protections Against Gastrointestinal Stress In Mice Treated With Lipopolysaccharide, Dallin R. Snow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk fat globule membrane surrounds the fat droplets of milk. It is a biopolymer containing primarily membrane glycoproteins and polar lipids which contribute to its properties as a possible neutraceutical. The aims of the studies were to determine if dietary milk fat globule membrane: (1) confers protection against colon carcinogenesis; and (2) promotes gut mucosal integrity while decreasing inflammation compared to diets containing corn oil or anhydrous milk fat.

Aim 1. Three dietary treatments differing only in the fat source were formulated: (1) AIN-76A, corn oil; (2) AIN-76A, anhydrous milk fat; and (3) AIN-76A, 50% milk fat globule membrane, 50% …

An Investigation Of The Utilization Of Soil Water And Nitrogen Among Diverse Forage Plant Species And Mixtures, Sallee Reynolds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Species diversity achieved by adding novel functional groups (warm-season grasses and non-leguminous forbs) to pasture land, along with traditional grasses and legumes, could aid in the capture of nutrients and water in pasture systems by offering complementary rooting architecture to aid in water and nitrogen uptake and decrease nitrogen leaching. Because these species may differ from commonly used grasses and legumes in their seasonal pattern of productivity, they could also extend or enhance growing-season productivity. The goal of this project is to better understand the role of plant diversity in 1) nitrogen use and 2) distribution of rooting dynamics and …

Residential Landscape Water Check Programs: Exploring A Conservation Tool, Diana T. Glenn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In response to drought and regional growth in the arid western United States, urban water demand management is increasingly important. Single family residences use approximately 60% of their water consumption to irrigate landscapes often in excess of plant water requirements. This study utilized a quasi-experimental design to investigate outdoor water consumption and assess the effectiveness of a landscape water check conservation program. Study objectives included describing a contextualized landscape system to reveal variables influencing water use, identifying better ways to evaluate landscape water use, and more effectively targeting and delivering water conservation programs.

The study was conducted during the 2004 …

Establishment And Aesthetic Value Of Native Grass, Legume, And Forb Species For Grassland Restoration In The Northern Intermountain West, Bridget M. Atkin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Interest in the restoration of landscapes native to the Intermountain West is growing as the value of these arid ecosystems is increasingly recognized. Many landscapes within the Intermountain region have been impacted by grazing, development, recreation, and other human-caused disturbances. The complex relationships within the native plant communities of these arid landscapes need to be well-understood biologically, while considering their aesthetic contribution, if restoration efforts are to succeed. Although the use of ecologically appropriate native species is increasing in popularity, there is discontinuity between aesthetics and meaningful ecological contributions. A series of studies was designed to aid in the restoration …

Triso Fuel Compact Thermal Conductivity Measurement Instrument Development, Colby Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thermal conductivity is an important thermophysical property needed for effectively predicting fuel performance. As part of the Next Generation Nuclear Plant (NGNP) program, the thermal conductivity of tri-isotropic (TRISO) fuel needs to be measured over a temperature range characteristic of its usage. The composite nature of TRISO fuel requires that measurement be performed over the entire length of the compact in a non-destructive manner. No existing measurement system is capable of performing such a measurement.

A measurement system has been designed based on the steady-state, guarded-comparative-longitudinal heat flow technique. The system as currently designed is capable of measuring cylindrical samples …

Parental Attitudes And Perceptions Related To Their Children's Physical Activity And Eating Patterns, Megan Leatham Dubois

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children's physical inactivity and poor eating patterns have received a great deal of attention in our country and worldwide. Studies have been conducted to identify determinates related to children's physical activity and eating patterns and to identify strategies for promoting positive behaviors. Parental support is a well-accepted determinate of children's physical activity and eating patterns. However, little qualitative research has been done to determine parental attitudes and perceptions related to this critical role.

First, the study sought to gain a greater understanding of parental perspectives on their children's physical activity and eating patterns. Second, the study examined parental attitudes and …

Effect Of Mica Content On Surface Infiltration Of Soils In Northwestern Kern County, California, Steven Keyes Stakland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A soils infiltration rate (IR) is the measured rate that soil is able to absorb water, either from precipitation or irrigation. A low IR can cause damage to crops if the necessary amount of water cannot penetrate to the plant roots in the time needed. The damage can be common in permanent plantings such as almond and pistachio orchards where regular tillage is avoided. This indicates a physical aspect to the problem because tillage increases IR. However, there is also an electrochemical side to infiltration problems because certain calcium surfactant treatments can increase IR. Various other methods have been used …

Ecology And Management Of A High Elevation Southern Range Greater Sage-Grouse Population: Vegetation Manipulation, Early Chick Survival, And Hunter Motivations, Michael R. Guttery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My research provided new information concerning the management, ecology, and conservation of greater sage-grouse (Centrocercus urophasianus). I report the results of an experiment using strategic intensive sheep grazing to enhance the quality of greater sage-grouse brood-rearing habitat. Although forb cover, an important component of brood-rearing habitat, responded positively to the grazing treatment, the response of other habitat variables was suppressed because the plots were not protected from domestic and wild herbivores during the years following the treatments. Measurements taken in grazing exclosures confirmed that herbivory by both large and small animals had significant impacts on vegetation. However, despite …

Mother-Child Attachment And Preschool Behavior Problems In Children With Developmental Delays, Mary S. Lamont

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Secure mother-child attachment has been found to be an important factor in the healthy emotional development of children and has been shown to have effects on child, adolescent, and adult behavior. Previous research has primarily focused on attachment in children who are typically developing. However, little research has been conducted in populations of children with developmental delays. The research thus far has suggested that medical situations, child disabilities and maternal emotions may affect interaction patterns between the mother and the child which may in turn influence the security of the mother-child attachment in children with developmental delays. This study contributes …

Destructive Testing Of Composite Precast Concrete Deck Panels And Built-Up Steel Plate Girders, Wesley J. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah Department of Transportation (UDOT) has implemented the use of precast concrete panels for bridge deck construction. A bridge utilizing these panels as a reconstruction method was decommissioned three years after the new deck installation, due to unrelated matters. Two sections of this bridge were salvaged and sent to Utah State University (USU) for destructive testing.

Each bridge section consisted of two built-up steel plate girders intact with the precast concrete deck panels. The precast panels were designed and constructed to achieve full composite action between the deck and built-up steel plate girders through the use of Nelson shear …

Plasticity And Damage In Bimodal Grain Size Al-5083: Microstructural Finite Element, Steven Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bimodal and nanocrystalline aluminum alloys are being investigated as stronger replacements for conventional polycrystalline aluminum alloys. Higher strengths are achieved by reducing the grain size of a metal; however, as the grain size is reduced the ductility diminishes. One solution that limits this decrease in ductility is the addition of a few microcrystalline grains into a nanocrystalline alloy, creating a bimodal microstructure that offers a better balance of strength and ductility. Two- and three-dimensional microstructural finite element (FE) simulations of monotonic and fatigue failures in Al-5083 having bimodal grain structures are conducted. To reduce the computational time and facilitate the …

Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For centuries, scientists have been intrigued by the high amount of biodiversity that is found in the deserts of North America. Recently, several studies have investigated the causes of the high diversity found in desert-dwelling mammals, reptiles, and amphibians. These studies have found that many of these organisms seem to have diversified in response to the same historical events. Little work has been done, however, on diverse desert-dwelling insect groups. In this dissertation, I investigate the patterns of genetic diversity in four groups of nocturnal wasps called velvet ants. I compare the patterns of genetic diversity to the historical events …

Spatial Light Dilution As A Technique For Conversion Of Solar Energy To Algal Biomass, Daniel J. Dye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A photobioreactor has been designed and developed to efficiently utilize solar irradiance through spatial dilution of sunlight. The concept of spatial light dilution is simple: incident sunlight is spread over a large surface area, thus reducing the photon flux density of the light. The implementation of this technique, however, is difficult. The reactor described within uses a new approach to spatial light dilution, utilizing recently-developed optical components to diffuse concentrated sunlight inside an algae culture. Preliminary productivity tests indicate a 2-3 fold increase in productivity per unit aperture (sunlight collection area) over a control reactor with direct-sunlight. Aperture productivity of …

The Effects Of Implementation Intentions On Volunteer Firefighter Exercise Behavior: A Randomized Controlled Study, Rodney L. Hammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The current study used a randomized control design to determine if an implementation intention intervention based on the Health Action Process Approach would increase exercise behavior in volunteer firefighters. One hundred forty-seven male and female volunteer firefighters from nine fire departments participated. The treatment group received a survey that prompted them to create exercise implementation intentions by describing "where," "when," and "how" they will exercise, while the control group survey included a general exercise message.

We hypothesized that the implementation intervention would increase exercise behavior while the general exercise message would have no effects on exercise, that earlier stage-of-change exercisers …

Outcomes And Predictive Correlates Of Injured Workers Who Have Undergone Percutaneous Facet Radiofrequency Neurotomy Of The Spine, Tyler J. Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Radiofrequency neurotomy is a pain intervention procedure designed to coagulate nerves that innervate a specific area of spinal vertebrae known as the facet joint. Despite moderate to strong research support for the efficacy of radiofrequency neurotomy to improve short-term subjective pain levels, much of the literature to date has used strict selection criteria and has not focused on functional and quality of life outcomes. Moreover, few studies have examined outcomes in worker's compensation patients or considered biopsychosocial predictive variables for the procedure. The current study aimed to characterize injured workers who have undergone radiofrequency neurotomy across a number of pre …

The Role Of Dopamine In Resistance To Change Of Operant Behavior, Stacey L. Quick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Psychological disorders such as autism, obsessive-compulsive disorder, drug addiction, and attention-deficit/hyperactivity disorder involve atypically persistent behavior and atypical activity of the neurotransmitter dopamine. Behavioral momentum theory states that the persistence of behavior in a context is determined by the reinforcement received previously in that context. Contexts previously associated with higher rates of reinforcement yield greater persistence of behavior than contexts previously associated with lower rates of reinforcement. According to a prominent hypothesis in behavioral neuroscience, dopamine mediates the incentive salience of a stimulus. A synthesis of behavioral momentum theory and the incentive salience hypothesis proposes similar roles for dopamine activity …

Kinetic, Mechanistic, And Structural Investigation Of Features Controlling Stereoselectivity Of (R)- And (S)-Hydroxypropyl Com Dehydrogenases From Xanthobacter Autrophicus Strain Py2, Dariusz Adam Sliwa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enantiopure alcohols are valuable intermediates in fine organic synthesis, in particular for preparation of biologically active compounds. The necessity of preparing single enantiomer drugs in an optically pure form has triggered much research, especially in the pharmaceutical industry. The biocatalytical production of chiral alcohols by alcohol dehydrogenase enzymes is characterized by the asymmetric reduction of the corresponding ketones, usually with high degree of stereoselectivity. The commercial value of the enzymes as stereoselective biocatalysts has been a significant driving force in understanding features that control their mechanism of catalysis and stereoselectivity. This work focuses on two enantiocomplementary dehydrogenase enzymes ((R …

Body Image Education As A Preventive Measure For Eating Disorders And Obesity In Ninth-Grade Students, Diana K. Keith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Obesity and eating disorders are major public health problems in the U.S. Prevention of these problems in childhood and adolescence is crucial to avoid medical complications and costs associated with these conditions. A growing body of research supports designing and implementing interventions to prevent obesity and eating disorders simultaneously by targeting common risk factors such as poor body image. This study explored the use of a body image education unit as a preventive measure for obesity and eating disorders. Ninth-grade students attending health class in a public school in Northern Utah (n = 117) were assigned to either an intervention …

Clarifying The Relationship Between Emotion Regulation, Gender, And Depression, Emi Sumida

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigates the relation between emotion regulation problems and clinical depression. One goal of the present study was to bring increased clarity and parsimony to how emotion regulation is presently measured by consolidating three widely used instruments. In addition, of interest was an investigation of whether particular emotion regulation problems and management strategies interact with gender to predict either severity of overall depression symptoms or the presence of a formal mood disorder diagnosis. The results clearly showed that irrespective of a person's gender, particular emotion regulation indicators, both singly, and in combination, are, indeed, more strongly related to the …

Pathophysiology And Clinical Implications Of Lower Respiratory Tract Infection (Lrti) With Respiratory Enteric Orphan Virus (Reovirus): Background And Experimental Evidence, Maret E. Bernard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background. Respiratory viral infection early in life is a predominant factor in the inception of episodic wheezing and development of asthma amongst young children [1] and a serious health challenge. Previous studies of lower respiratory tract infections (LRTI) with respiratory syncytial virus (RSV) in animal models have indicated that early life viral exposure results in dysregulated neuroimmune interactions and altered synthesis/release of pro-inflammatory neuropeptides generating increased airway reactivity and neurogenic-inflammation. Similar to RSV, respiratory enteric orphan virus (Reovirus) is a common respiratory pathogen associated with pulmonary infections in children. Also, reovirus pulmonary infection has been shown to induce increased collagen …

Where Independence Meets Its Match: The Intersection Of Musical Identity, Record Promotion And College Radio Programming, Aaron J. Hawley

Graduate Theses, Dissertations, and Problem Reports (ETD)

College Radio has long been championed for being one of the last independent voices on a radio dial dominated by corporate for-profit stations. While corporate stations program their playlists towards whatever is on the charts, independent programming has long been part of the appeal of college radio. However, college radio music directors are in constant contact with record promoters whose sole goal is to get their clients' records played on-air. While a notion of independence is central to college radio's musical identity, these record promoters hold a great deal of power in the decision making process. Upon investigation at WVU …

A Study On Physical Factors That May Influence The Spread And Occurrence Of Influenza, Kedar V. Panday

Graduate Theses, Dissertations, and Problem Reports (ETD)

Influenza is one of respiratory infections causing the highest morbidity and mortality rates. Every day tens of millions of people suffer from virus infection worldwide with varying severity and with a high economic impact. Influenza transmission from person to person occurs in various ways. This study is an attempt to understand airborne transmission in indoor locations by examining the relation between environmental parameters such as temperature and relative humidity with the number of influenza like illness (ILI) cases. It is proposed that the pattern of influenza activity is primarily a function of indoor relative humidity in temperate regions. This conclusion …

Reframing Antitrust In Light Of Scientific Revolution: Accounting For Transaction Costs In Rule Of Reason Analysis, Alan J. Meese

Faculty Publications

This Article contends that modern rule of reason analysis, informed by workable competition’s partial equilibrium trade-off paradigm, is suitable for evaluating only a subset of agreements that may reduce transaction costs. The Article distinguishes between “technological” and “non-technological” transaction costs. Technological transaction costs entail the bargaining and information costs first emphasized by Ronald Coase, while non-technological transaction costs result from more fundamental departures from perfect competition, departures creating a risk of opportunism that accompanies relationship-specific investments. Modern law does accurately assess restraints that may reduce technological transaction costs—costs that are analogous to the sort of production costs recognized by the …
