Accessing Healthy Food: Behavioral And Environmental Determinants Among Low-Income Populations, Abiodun Tolulope Atoloye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

On average, low-income individuals have poorer diet quality compared to their high-income counterparts. However, improved food access may offer opportunities to improve diet among this population. This study examines how the low-income population navigates between barriers, resources, and opportunities to acquire healthy foods in different settings.

Chapter 3 examined how the use of a farmers’ market incentive program among the low-income population impacts F&V consumption. We observed no effect on F&V consumption due to program participation but users of the program have a significantly higher F&V consumption than non-users. Chapter 4 identified transportation difficulties as a barrier to the uptake …

Activity Tracker Measurement Of Physical Activity And Sedentary Time In The Workplace Including An Intervention Involving Reminders To Move, Cassie Dance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sedentary time and physical inactivity have negative impacts on health and health costs as well as an impact on workplace wellbeing. There is evidence that people are more sedentary and engage in less physical activity on work days. Additionally, sedentary behavior has been found to increase distress and negative mood. Activity trackers such as Fitbits are a useful way to collect and intervene on sedentary behavior and potentially impact other factors of workplace wellbeing in real time and promote self-monitoring. The reminder to move prompts that are now part of Fitbit models provide an innovative and simple way to intervene …

Investigating The Roles Of Bacterial Endosymbionts In The Evolution Of Adelgidae (Hemiptera: Sternorrhyncha), Kathryn M. Weglarz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Insects form close partnerships, or symbioses, with bacteria. These partnerships allow the insects to use resources that would be unavailable to them otherwise. Certain insects, hemipterans, are able to feed on nutrient-poor plant-sap because these bacteria supplement their diets. While this association is beneficial for both the insect and bacteria, it also comes with consequences: the genomes of bacterial symbionts typically undergo extreme degradation, becoming small and lacking many genes necessary for typical bacterial functioning. In the Hemiptera, aphids, mealybugs, cicadas, true bugs, and their relatives, these bacterial partnerships tend to be stable over millions of years. However, adelgids (Aphidoidea: …

Herbage Characteristics Affecting Intake By Dairy Heifers Grazing Grass-Monoculture And Grass-Birdsfoot Trefoil Pastures, Marcus F. Rose

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pasture-based dairies have become more prevalent in recent years due to a higher proportion of organic milk demand and production. Organic certification requires that animals must graze at least 120 days in each growing season. However, dry matter intake is often limited when dairy animals receive most of their herbage from pasture, resulting in lower animal performance and milk production. The purpose of this study was to analyze the complimentary effect of high energy grasses with birdsfoot trefoil (BFT) tannins to improve intake of dairy heifers. Jersey heifers were rotationally grazed for 105 days in 2017 and 2018 on eight …

Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beef cattle production is highly criticized because of the high use of land and water resources, and by the pollution (e.g., the gas methane in a cow’s breath and nitrogen in urine) produced by cows fed in feedlots. In contrast to feedlots diets and grasses, some plants (e.g., legumes) contain bioactive compounds (condensed tannins) that reduce pollution and enhance animal nutrition. In my research, I observed that cows grazing a tannin-containing legume (birdsfoot trefoil; BFT) had methane emissions similar to cows fed a feedlot ration with comparable weight gains. Cows in the BFT treatment gained more weight than cows grazing …

A Model Explaining Medusahead Invasion And Novel Targeted Grazing Approaches Of Control, Casey N. Spackman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Medusahead (Taeniatherum caput-medusae (L.) Nevski) is currently one of the biggest threats to rangelands and livestock operations in the Western US. High silica concentrations in medusahead contribute to its invasiveness. I developed a model to explain how silica is involved in the invasion process, and attempted to manipulate silica to increase use of the grass by livestock. Experiments were conducted to determine: 1) whether rotational grazing on established forages of improved nutritional quality would provide supplemental nutrients to increase cattle use of medusahead; 2) evaluate intake of and preference for medusahead treated with a glyphosate herbicide at different rates …

Evaluation Of A Computer-Based Observer-Effect Training On Mothers' Vocal Imitation Of Their Infant, Kerry A. Shea

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Infants begin to learn important skills, such as contingency learning, social referencing, and joint attention through everyday interactions with their environment. When infants learn that their behavior produces a change in the environment (e.g., attention from others), infants engage in behavior that produces that effect (e.g., increases in smiling sustained engagement. When mothers and other caregivers respond immediately to infant behavior, they help their infant learn that the infant’s own behavior is effective, producing a change in the environment. The current investigation evaluated the effect of a computer-based training that aimed at teaching mothers to play a vocal-imitation contingency-learning game. …

Navigating Adulthood: Exploring The Impact Of A High School Life-Skills Course On Adulthood Transition Experiences, Lacee R. Boschetto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to explore the adulthood transition experiences of Utah high-school graduates, with heightened focus on the application value of educational content from the course, Adult Roles. The purpose of the study was identified through experiential interactions with high-school graduates, and was supported by research on 21st century adulthood transitions shown to divert away from traditional adulthood markers. The inconsistency between modern adulthood transition behaviors and traditionally held adulthood assumptions lead to negative perceptions about young adult’s capability to adapt to adulthood. The researcher was motivated to investigate opportunities that may provide increased preparation for the transition into …

Organizational Capacity Of Nonprofit Organizations In Rural Areas Of The United States: A Scoping Review, Jayme E. Walters

Sociology, Social Work and Anthropology Faculty Publications

Rural America is facing a plethora of problems related to poverty, crime, health, and education. Nonprofit organizations serve a vital role in rural communities by providing services and advocacy to residents. Yet, it is unknown if rural nonprofits have the means to effectively address the complex issues before them. This study examines the results of scoping review which characterizes the state of empirical knowledge regarding the organizational capacity of rural nonprofits in the United States. Fifteen articles from the past decade uncovered challenges and strengths related to organizational capacity, though more research is necessary to inform funders and educators.

Renegotiating Gender Roles And Cultivation Practices In The Nepali Mid-Hills: Unpacking The Feminization Of Agriculture, Kaitlyn Spangler, Maria Elsia Christie

Environment and Society Student Research

The feminization of agriculture narrative has been reproduced in development literature as an oversimplified metric of empowerment through changes in women’s labor and managerial roles with little attention to individuals’ heterogeneous livelihoods. Grounded in feminist political ecology (FPE), we sought to critically understand how labor and managerial feminization interact with changing agricultural practices. Working with a local NGO as part of an international, donor-funded research-for-development project, we conducted semi-structured interviews, focus group discussions, and participant observation with over 100 farmers in Mid-Western Nepal in 2017. Household structure and headship are dynamic in the context of male out-migration, pushing women to …

Is The “Preventing Animal Cruelty And Torture Act” A Step In The Right Direction?, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

On October 22nd, Congress unanimously passed the “Preventing Animal Cruelty and Torture Act.” The law makes certain acts of cruelty against animals federal crimes. Before the federal law was passed, legislation protecting animals was largely a matter reserved for state legislatures. The law was met with praise from both private citizens and animal welfare organizations like the American Society for the Prevention of Cruelty to Animals (ASPCA).

Body Condition Scoring For Horses, Karl Hoopes, Eric Thacker, Linden Greenhalgh

All Current Publications

Horse enthusiasts are often concerned about their horse’s health, appearance and performance. A major key to accomplishing these three goals is to keep your horse at a desirable body condition, or degree of fat cover. However, being able to accurately evaluate a horse to tell if they are over or underweight has been a subjective practice for many years. As with all aspects of horse ownership, horse owners have different opinions on what is an ideal body weight for an individual horse. Also, because horses come in all shapes and sizes, many horse owners are not able to objectively evaluate …

Ecology Center Publications

Across the northern hemisphere, six species of aspen (Populus spp.) play a disproportionately important role in promoting biodiversity, sequestering carbon, limiting forest disturbances, and providing other ecosystem services. In many regions, aspen can maintain canopy dominance for decades to centuries as the sole major broadleaf trees in forested landscapes otherwise dominated by conifers. Aspen ecosystems are valued for many reasons, but here we highlight their potential as key contributors to regional and global biodiversity. We begin with an overview of the aspens’ ecological and economic roles. We then present a systematic literature analysis to assess topics of aspen …

Global Imprint Of Mycorrhizal Fungi On Whole-Plant Nutrient Economics, Colin Averill, Jennifer M. Bhatnagar, Michael C. Dietze, William D. Pearse, Stephanie N. Kivlin

Biology Faculty Publications

Mycorrhizal fungi are critical members of the plant microbiome, forming a symbiosis with the roots of most plants on Earth. Most plant species partner with either arbuscular or ectomycorrhizal fungi, and these symbioses are thought to represent plant adaptations to fast and slow soil nutrient cycling rates. This generates a second hypothesis, that arbuscular and ectomycorrhizal plant species traits complement and reinforce these fungal strategies, resulting in nutrient acquisitive vs. conservative plant trait profiles. Here we analyzed 17,764 species level trait observations from 2,940 woody plant species to show that mycorrhizal plants differ systematically in nitrogen and phosphorus economic traits. …

North American Hard Yellow Liver Disease: An Old Problem Readdressed, Bryan L. Stegelmeier, Meredyth Jones, Christopher P. Womack, T Zane Davis, Dale R. Gardner

Poisonous Plant Research (PPR)

Hard yellow liver disease or fatty cirrhosis periodically affects cattle, sheep, goats, pronghorn antelope (Antilocapra americana) and whitetail deer (Odocoileus virginianus texanus) within several Texas counties in the United States. Clinically it presents as chronic liver disease with progressive hepatic necrosis and fibrosis, icterus and liver failure. The damaged livers are yellow and many have multiple firm, often gritty foci that are scattered throughout all lobes. Early investigations included feeding studies using potential toxic plants, climate and forage studies, infectious disease surveys and various mycotoxin studies and analyses. None have definitively reproduced the disease or identified the inciting …

Investment Of Both Essential Fatty And Amino Acids To Immunity Varies Depending On Reproductive Stage, Taylor V. Pettit, R. John Pettit, Andrew M. Durso, Susannah S. French

Ecology Center Publications

Trade‐offs among the key life‐history traits of reproduction and immunity have been widely documented. However, the currency in use is not well‐understood. We investigated how reproducing female side‐blotched lizards, Uta stansburiana, allocate lipids versus proteins when given an immune challenge. We tested whether lizards would invest more in reproduction or immunity depending on reproductive stage. Females were given stable isotopes (¹⁵N‐leucine and ¹³C‐1‐palmitic acid), maintained on a regular diet and given either a cutaneous biopsy or a sham biopsy (control). Stable isotopes were monitored and analyzed in feces and uric acid, skin biopsies, eggs, and toe …

Data From: Cavitation Clusters In Lipid Systems – The Generation Of A Bifurcated Streamer And The Dual Collapse Of A Bubble Cluster, Silvana Martini, Peter Birkin, Tadd T. Truscott

Browse all Datasets

Over the past decade several studies have reported the use of high intensity ultrasound (HIU) to induce the crystallization of lipids. The effect that HIU has on lipid crystallization is usually attributed to the generation of cavities but acoustic cavitation has never been fully explored in lipids. The dynamics of a particular cavitation cluster next to a piston like emitter in an oil, was investigated in this study. The lipid systems, which are important in food processing, are studied with high-speed camera imaging, laser scattering and pressure measurements. A sequence of stable clusters were noted. In addition, a bifurcated streamer …
