The bison market has been becoming increasingly popular within recent years. However, this market is challenging for producers due to disease concerns, aggressive bison behaviors, nutritional and facility requirements and market risks for bison operations. Since most bison data began in 2020, forecasting bison meat prices remains difficult. This raises an important question: can bison meat cut prices be effectively hedged by using live cattle futures prices? This paper examines USDA bison meat cut price data and live cattle futures prices to determine potential correlations. A regression analysis, along with a dummy variable approach is utilized to evaluate the relationship. …

A Study Of Regulatory Compliance In U.S. Nursing Homes, Patrick Schumacher

Electronic Theses & Dissertations (2024 - present)

The federal government is responsible for ensuring that nursing homes comply with regulations designed to protect residents from abuse, neglect, and substandard care. To this end, the Centers for Medicare and Medicaid Services (CMS) partners with states to conduct onsite inspections of nursing homes, during which regulators may identify violations. The agency can take one or more actions in response to violations, including imposing civil money penalties (fines), appointing a state monitor, or mandating remedial education for staff. Despite this regulatory framework, the quality of care in nursing homes remains poor, with many facilities failing to protect the well-being of …

Retrospective Recall Of Food Parenting Practices During Childhood, Current Adult Health Outcomes, And Intuitive Eating, Katelyn Bretzel

UNF Graduate Theses and Dissertations

Emerging adulthood is a time of exploration, change, and emerging independence, which can make individuals vulnerable to health changes. Previous research demonstrates that food parenting practices (coercive control, structure, and autonomy support) during childhood may relate to health outcomes into adulthood. In the current study, it was hypothesized that intuitive eating during emerging adulthood would be associated with food parenting practices; with coercive control and structure practices hindering intuitive eating, while autonomy support encourages it. The current study tested these relationships further, utilizing retrospective reports of food parenting practices during childhood and examining their relation to intuitive eating, dietary quality, …

Toxic Sweetness And Abstinence: The Citationality Of Robert Lustig's Anti-Sugar Rhetoric, Tyler J. Snelling

Iowa Journal of Communication

Robert Lustig’s (2009) lecture on YouTube “Sugar: The Bitter Truth” animated a widespread conversation about whether sugar poisons bodies. Discourse following the lecture warrants analysis to gage how the meaning of the lecture transformed from a critique of food systems into individual actions. I argue that citationality of “Sugar: The Bitter Truth” fosters healthism by grounding sugar’s toxicity in scientific and affective reasoning that compels individual actions like abstinence from sugar. The pediatrician's lecture enabled the construction of a supposedly "moral eater" who removes sugar from consumption to avoid the poison's consequences. This paper offers tools for examining the spread …

Moldy Whoppers And Vitamin Donuts: Health Halos In Food Advertisements, Debbie Danowski

Iowa Journal of Communication

Health Halos have been used in food advertisements since the late nineteenth and early twentieth centuries when the advent of mass-produced consumer goods took hold and manufactures began advertising their products. It wasn’t until nearly eight decades later, however, that theoretical framework specifically involving health halos was recognized in advertising research. Though subsequent research suggests the effectiveness of health halos in making unhealthy food appear healthier, there has been little, if any, attention given to identification of the health halos used in food advertising. This study aims to fill the gap by identifying two of the health halo techniques used …

Impact Of A 24 H Feed Withdrawal On Active Nutrient Transport, Intestinal Morphology, And Gene Expression In The Equine Small And Large Intestine, Blaire E. Aldridge-Dean, Timothy B. Lescun, John Scott Radcliffe

Animal and Food Sciences Faculty Publications

Horses are often subjected to short-term feed withdrawal (FW) pre- or post-surgery to reduce anesthetic complications. However, removing nutrients from the intestinal lumen may negatively impact intestinal health. Thirteen horses were used to determine the effects of a 24 h FW on gut barrier function, active nutrient transport, transporter gene expression, and intestinal morphology. Following 0 or 24 h FW (0FW or 24FW, respectively), horses were euthanized via overdose of sodium pentobarbital and sodium phenytoin, and segments of proximal jejunum (PJ), mid jejunum (MJ), ileum (Il), and right ventral colon (RVC) were harvested for histology (PJ and Il), gene expression, …

Piglet Nursing Location Along The Sow’S Udder Line Affects Piglet Weight Gain And Subsequent Weaning Weight, Shannon Dierking, Harold J. Monegue, Merlin Lindemann

Animal and Food Sciences Faculty Publications

Background: There is a linear correlation between piglet weaning weight and average daily gain during the post-nursery period. A key factor that influences piglet weight gain during lactation is milk intake. Thus, the variation in piglet weaning weight is hypothesized to be, to some extent, a result of differences in milk production among individual mammary glands. Objective: The objective of this study was to evaluate the impact of piglet nursing location throughout lactation on piglet weaning weight, with a secondary objective of determining the impact of piglet birth weight on nursing location selection. Methods: Teat pairs were labeled from anterior …

Animal and Food Sciences Faculty Publications

Transportation at weaning is an integral component of the American swine industry. However, the long-term effects on growth performance have not been well characterized. Previous research suggests transportation causes weight loss immediately following weaning, but few studies have followed this effect further than 7 d post-weaning, with transport causing decreased body weight in those that have. In experiment 1, average weight pigs at 20 ± 1.3 d of age were weaned and either 1) transported for 9 hour without feed and water (TR), 2) had their feed and water restricted for 9 hour (FR), or 3) were weaned and provided …

Effects Of Single-Cell Dietary Protein Sources On Feeding, Growth, And Resource Allocation In The Juvenile Sea Urchin Lytechinus Variegatus, Darrien Jamila De Jesus

All ETDs from UAB

An understanding of nutrition can improve culture of sea urchins, whether as a research model or in the production of seafood products. Macronutrients, including dietary protein sources, can affect growth and reproductive profiles and alter resource allocation to somatic and gametic tissues. Although sea urchins in culture can be fed natural products, diet formulations using various ingredients can be developed to reliably produce desired outcomes. Single-cell protein sources represent a potential alternative to current industry standards of animal-derived protein sources such as fish and squid meal, which are becoming increasingly overfished and expensive. In the present study, we evaluated the …

Maternal Immune Activation Causes Oligodendrocyte Deficits In The Hypothalamus, Kate Miller

All ETDs from UAB

Maternal immune activation (MIA) refers to the occurrence of an inflammatory immune response during any stage of pregnancy. This manifests as the upregulation of proinflammatory cytokines and can be caused by air pollution, obesity, or viral infection. When this occurs during the first trimester in humans, it increases the offspring’s susceptibility to developing neuropsychiatric disorders such as autism (ASD) and schizophrenia (SZ), in males more commonly than females. In addition to behavioral manifestations of neuropsychiatric disorders, metabolic syndrome (MetS) is a common comorbidity, defined as the co-occurrence of three or more symptoms including but not limited to hyperlipidemia, hypertension, and …

Reducing Stress: The Role Of The Rcl Operon In Bacterial Stress Response To Hypothiocyanite, Julia Meredith

All ETDs from UAB

The human immune system utilizes a variety of weapons against bacterial communities within the body, which allow it to control the overall microbial population. Understanding how some bacterial species are able to better deal with and survive damage by the immune system while others are not, can help us elucidate the complex relationship between us and our microbiome. One tool that immune cells use for microbial control is the potent oxidant hypothiocyanite/hypothiocyanous acid (-OSCN/HOSCN). The response mounted by Escherichia coli and other bacterial species in order to survive damage caused by HOSCN is the focus of this dissertation. In the …

Therapeutic Implications Of Fractionated Radiotherapy And Marcks’ Regulation Of Tunneling Nanotubes In Glioblastoma, Lauren Catherine Nassour-Caswell

All ETDs from UAB

Glioblastoma (GBM) is the most common primary brain malignancy in adults and the gradual development of treatment resistance prevents patients from achieving remission. A primary objective in the field is to devise strategies to overcome this. We predicted this could be achieved by improving existing therapies, creating better models to study GBM, and by identifying a potential therapeutic target. Fractionated radiotherapy (RT) has been used in GBM standard of care for over a century but does not account for GBM heterogeneity. We first hypothesized that in silico mathematical modeling would be a useful tool for cytotoxicity prediction. While this model …
