Food Stamp Enrollment And Mental Health: An Implicit Tax On The Poor, James Calvin Hasbany

Economics

Objectives. This study examines whether food stamp participation status impacts the mental health of its recipients.

Methods. We use 2017 data from the Michigan Panel Study of Income Dynamics to construct a propensity score model to match treated and control individuals, circumventing inherent selection bias and estimating causal effects.

Results. We find that enrolling in food stamps within the past 30 days increases the frequency of emotional distress over the same timeframe, manifesting specifically in more frequent feelings of sadness, nervousness, hopelessness, ‘everything being an effort,’ and worthlessness.

Conclusions. Food stamp enrollment harms mental health more than it benefits it, …

Physical Activity Guidelines For People With Alzheimer’S Disease Of Various Ambulatory And Cognitive Status, Amanda Katherine Wright

Kinesiology and Public Health

With the rapidly growing elderly population in the United States, the number of people diagnosed with dementia and Alzheimer’s Disease (AD) is increasing dramatically. For these patients, it is crucial to slow the rate of progression. Research has proven that exercise improves cognition, and recent findings suggest a similar association among those with AD. However, this is complicated by the large majority of AD patients becoming non-ambulatory as the disease progresses. Thus, there is a large gap in the literature to meet the needs of non-ambulatory AD patients working to slow their disease’s progression. The first purpose of this article …

The Effects Of Wort Oxygenation Scenarios On Fermentation Performance, Volatile Flavor Compound Development, And Flavor Stability In High Gravity Brewing, Ben Jabson

Master's Theses

High gravity (HG) brewing has become the most used strategy for maximizing fermenter productivity in commercial brewing. While HG brewing has many benefits, the additional stress placed on the yeast due to the higher concentration of fermentable sugars in the wort can negatively impact fermentation performance and flavor compound formation. A proper dissolved oxygen (DO) level is vital to guarantee adequate yeast performance during HG fermentations. Dissolved oxygen is vital to yeast viability throughout the fermentation process, as yeast requires oxygen to synthesize vital cell membrane components needed for continued anaerobic growth and cell division. Previous research has demonstrated the …

Effect Of Simulated Storage And Distribution On Listeria Innocua Growth In Non-Traditional Salad Ingredients, Emma L. Sandquist

Master's Theses

The fresh-cut produce industry has seen expansive growth in recent years, to meet consumer demand ready-to-eat (RTE) salads have included the use of non-traditional ingredients. Uncommon ingredients include beet greens, kale, broccoli stalk, and Brussels sprouts, since these ingredients have not historically been consumed raw, potential food safety issues should be reassessed. Current processing technologies include produce washes that can reduce microbial levels but do not eradicate all populations. The lack of a kill step in produce processing emphasizes the need to minimize pathogen contamination during production and growth during a product’s shelf life.

Positive Parenting Approaches And Their Association With Child Eating And Weight: A Narrative Review From Infancy To Adolescence, Katherine N. Balantekin, Stephanie Anzman-Frasca, Lori A. Francis, Alison K. Ventura, Jennifer O. Fisher, Susan L. Johnson

Kinesiology and Public Health

Parents play a critical role in the development of children's eating behaviours and weight status, serving as providers, models and regulators of the food environment. Many research reviews have focused on the robust body of evidence on coercive control in feeding: how parenting practices such as restriction and pressure to eat increase children's risk for developing undesirable eating behaviours and unhealthy weight outcomes. Fewer reviews adopt a strengths-based perspective focusing on the ways that parents can actively support the development of healthy eating behaviours and weight trajectories. Emerging research on such positive parenting styles and practices offers solutions beyond the …

A Naturalistic Ethic Supporting A Vegan Diet, Michael Morris

Between the Species

Nutritional evidence suggests that a vegan diet is the most adaptive one for humans. An ethical principle based on following our biological nature (naturalistic ethic) could therefore provide additional support for a vegan diet. However, some argue that humans in the natural world could not eat a vegan diet, since it relies on supplements, particularly vitamin B12. This leads to the conclusion that humans are naturally omnivores, and therefore our natural diet should include small amounts of animal products.

Three approaches to this conclusion are discussed. The first rejects a naturalistic ethic in favour of normative principles based on animal …

Abalone Recruitment In Abalone Recruitment In Low-Density And Aggregated Populations Facing Climatic Stress, Ryan K. Walter

Physics

Understanding spatial and temporal patterns in the recruitment of marine invertebrates with complex life histories remains a critical knowledge gap in marine ecology and fisheries. As marine invertebrates are facing multiple stressors from overfishing and climatic stress, it is important to evaluate the conditions that facilitate recruitment in low-density populations. The red abalone Haliolis rufescens historically supported an economically important fishery in California, but the fishery was sequentially closed as stocks declined, and the last fished area was closed in 2018 following the collapse of the kelp forests in Northern California. Here, red abalone recruitment was evaluated annually from 2012 …

Maleic Anhydride Compatibilized Peach Waste As Filler In Polypropylene And High Density Polyethylene Biocomposites, Caralyn Wong, Stephanie Jung, Joongmin Shin, Ajay Kathuria

Master's Theses

It is estimated that roughly 103, 515 tons of peach waste is produced annually in the US. The majority of the waste is disposed of in landfills, which contributes to climate change as they release 93 million metric tons of CO₂ equivalent. Peach waste principally consists of remaining stone and seed after flesh removal. The agro-waste includes both cellulose and lignin, which can be utilized as a filler in plastic packaging to reduce carbon footprints and material cost. The objectives of this research are (1) to develop peach flour (PF)-filled biocomposites with a polyolefin matrix using maleic anhydride-g-high density …

Agricultural Conservation Decision-Making Under Environmental Risk And Uncertainty On The California Central Coast, Diego Rivera

Master of Science in Environmental Sciences and Management Projects

Global climate change is a process that is, in part, caused by agricultural practices, and will adversely affect agricultural operations, especially vineyards. The objective of this project is to determine how viticulturalists in Paso Robles, California view global climate change and how they use conservation practices that combat climate change and prepare for the associated negative effects. Interviews were conducted with vineyard advisors and managers to determine what general risks associated with wine grape production exist for their operations, and whether wine advisors and producers perceive global climate change to be one of those risks. The interview responses were then …

Exploring The Relationships Between Mothers' Use Of Food To Soothe, Feeding Type And Mode, Maternal Feeding Style, Infant Behavior, And Infant Weight-Related Outcomes During Early Infancy, Megan K. Hupp

Master's Theses

Rapid infant weight gain (RWG) in the first six months postpartum is a strong predictor for obesity during childhood and adolescence. Although biological factors can influence infant weight gain trajectories, the modifiable factor of parent feeding practices can also have an influence. The use of food to soothe (FTS), or the act of feeding a child when he/she is upset for reasons other than hunger, has been associated with unhealthy eating behaviors and less-favorable weight outcomes in children and older infants. However, limited studies have explored the use of FTS during early infancy before the introduction of solids foods. The …
