An Investigation Of Dietary Supplementation As A Potential Source Of Nutrition Misinformation Hindering The Development Of Healthy Eating Habits In The College Population, Mary Dimmick

Undergraduate Honors Capstone Projects

Current dietary supplement legislation allows nutrition misinformation to flourish; misleading structure‐function and health‐claims now abound on supplement labels. Meanwhile, college students tend to be open to experimentation and exploration. Hence, this study’s objective was to discover if students at USU are being influenced by such claims to unjustifiably take dietary supplements in a manner which hinders the development of healthy eating habits. During August of 2009, 1,300 USU freshmen were invited to voluntarily participate in an on‐line survey concerning dietary patterns which included a section about dietary supplementation. Five‐hundred‐and‐twelve completed the survey after providing informed written consent to participate. The …

Parental Perspectives Of Play With Preschool Children, Danielle M. Jensen

Bracketing The Age Of The Great Gallery Rock Art Panel In Horseshoe Canyon, Utah By Osl Dating Of Associated Alluvial Terraces, Melissa S. Jackson

Undergraduate Honors Capstone Projects

Barrier Canyon Style rock art (BCS) is a unique rock art style indigenous to the middle Colorado Plateau that is of an unknown age and formed by a combination of wall preparation, rock pecking, and application of multiple pigments. It is characterized by broad-shouldered, mummy-like figures that commonly lack limbs and facial details but are accompanied by animated and realistic representations of animals. The age of BCS art remains unknown in spite of attempts to radiocarbon date accessory brush fibers in the mineral-based pigment. Yet a range of age hypotheses exist, from as young as 1600 AD to as old …

Invisible Abuse: Utah's Response To Emotional Child Abuse, Janae Sirrine

Undergraduate Honors Capstone Projects

The very nature of emotional child abuse makes it difficult to detect and report. Nevertheless, scholars and professionals in the field of child welfare have identified emotional abuse as being equally detrimental to children as physical abuse and neglect. Many states, including Utah, have unclear definitions of emotional child abuse. The purpose of this study is to interpret how Utah has used its statute on emotional abuse in the court system and whether the current definition of emotional child abuse has given Utah’s courts enough information and direction to prosecute those who emotionally abuse children. Data was collected by researching …

Drivers Of Plant Population Dynamics In Three Arid To Subhumid Ecosystems, Luke J. Zachmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the relative importance of density-dependent and density-independent factors in driving population dynamics is one of the oldest challenges in ecology, and may play a critical role in predicting the effects of climate change on populations. We used long-term observational data to describe patterns in plant population regulation for 57 forb and grass species from three different ecosystems (arid desert grassland, semiarid sagebrush steppe, and subhumid mixed-grass prairie). Using a hierarchical partitioning approach, we (i) quantified the relative influence of conspecific density, heterospecific composition, and climate on temporal variation in population growth rates, and (ii) asked how the relative importance …

Intercomparison Of Prism And Daymet Temperature Interpolation From 1980 To 2003, Rebecca A. Scully

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As ecosystem modeling becomes increasingly integrated with Geographic Information Systems (GIS) there is a rise in demand for spatially and temporally continuous meteorological data. But in order to justify management decisions or to provide robust scientific insights, the accuracy of meteorological data used as model input must be thoroughly quantified. Current methods to create spatially continuous climate data from discrete weather station data include inverse distance weighting, geostatistical techniques such as kriging and splines, local regression models such as Parameter-Elevation Regression on Independent Slope Model (PRISM) and Daymet, and regional regression models. For the conterminous United States, PRISM and Daymet …

Comparison Of Agricultural Area Source Ammonia Gas Concentration And Flux Measurements, Emyrei Reese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to observe the effects of selenium from plant material in sheep after a single, oral dose. Purified sodium selenite and selenomethionine were given as positive controls. The plant Symphyotrichum spathulatum (Western Mountain Aster) was collected, analyzed for selenium content, and administered orally to sheep at varying doses according to body weight. Clinical signs were observed for 7 days during which time whole blood, serum, and expired air were collected. Following euthanasia, tissues were collected for histopathological analysis and mineral analysis.

Clinical signs were less apparent than expected and included depression and mild dyspnea in sheep receiving …

Altering Positive/Negative Interaction Ratios In Relationships Of Mothers And Young Children: A Preliminary Investigation, Andrew B. Armstrong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Based on classic marital research of John Gottman, a popular notion exists that interpersonal relationships thrive when the number of positive interactions outweighs negative interactions by a ratio of five to one. Though many have given similar advice for parents and caregivers, Gottman's findings and methodology may not generalize to relationships of parents and young children. Were similar ratio findings to be validated for parent-child relationships, explicit ratio advice may be incorporated as a component of clinical practice (e.g., behavioral parent training). To begin investigating potential clinical implications, a project was conducted that examined mothers' ability to achieve prescribed ratios …

Finding, Nurturing, And Instilling Hope In Family Therapy, Joseph Daniel Tschudy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of a personal theory of therapy and change is an integral part of the training and educational philosophies of the Marriage and Family Therapy Program at Utah State University. This personal theory attempts to identify and explain each student's beliefs regarding the specific mechanisms by which change occurs, thus providing a therapeutic backbone from which one may integrate various interventions, ideas, concepts, and approaches to therapy. As one engages in the process of integration, it becomes critical for students to evaluate their performances. A thorough self-evaluation that includes the utilization of scientific methods leads to the development of …

Introduced Sport Fish And Fish Conservation In A Novel Food Web: Evidence Of Predatory Impact, Kevin Lee Landom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study addressed a fundamental question in applied ecology and conservation; what is the predatory impact of introduced piscivorous sport fish on imperiled native fish populations? More specifically, which of many introduced species and size-classes represent the greatest threats and should be targeted for control? In order to explore this important question, an integrated analysis of stable isotopes, quantified observed diet analysis, and stable isotope mass-balance models were used to quantify trophic interactions. These tools were used to construct food web models that were then compared to draw inferences regarding the relative contribution of prey fish, including rare native fish, …

Mechanisms Of The Extreme Sensitivity Of Turkeys To Aflatoxin B1, Sumit Rawal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The pathogenesis of hepatotoxic and hepatocarcinogenic actions of the mycotoxin aflatoxin B1 (AFB1) involves initial bioactivation by microsomal cytochrome P450s (P450) to a reactive and electrophilic intermediate, exo-aflatoxin B1-8,9-epoxide (exo-AFBO). Poultry, especially turkeys, are extremely sensitive to AFB1, a condition associated with efficient epoxidation by P450s. The purpose of this research was to 1) discover and characterize the P450s in turkey liver responsible for AFB1 bioactivation, and 2) determine the relative importance of these P450s in turkey liver.

Initial investigations led to the discovery of CYP1A5. We then identified CYP3A37, a human CYP3A4 homologue from turkey liver, …

Snowshoe Hare And Forest Structure Relationships In Western Wyoming, Nathan Daniel Berg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Snowshoe hares (Lepus americanus) are a critically important prey species for Canada lynx (Lynx canadensis). Determination of snowshoe hare distribution and abundance is needed in western Wyoming for lynx conservation. We used linear regression to examine the correlations between snowshoe hare density, as determined by mark-recapture estimates, and fecal pellet plot counts on both uncleared and annually cleared plots on the Bridger-Teton National Forest, western Wyoming. We found significant correlations between hare density estimates and fecal pellet counts for both uncleared and annually cleared pellet counts; however the relationship was much stronger for annually cleared pellet …

Development Of A Laboratory Based System For Selecting Insect Pathogenic Fungi With Greatest Potential For Success In The Field, Chad Alton Keyser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many insects are important agricultural pests, and active control is necessary to keep them at abeyance. The naturally occurring entomopathogenic fungus Metarhizium is a promising tool to control pest insects, and its use avoids the well-known harmful side effects of chemical pesticides. Thousands of unique isolates of Metarhizium exist throughout the world. These isolates vary widely in their ability to cause infection and to tolerate stressful habitats. The research reported here tests the THESIS: A laboratory-based system can be devised that identifies, from among many Metarhizium isolates, those isolates with the greatest potential for successful biological control of pest insects …
