An Interpretative Phenomenological Study Of Undergraduate Student Wellness: Exploring Generation Z Student Wellness Experiences During The Covid-19 Pandemic, Kristen Pepin

Open Access Dissertations

Qualitative research exploring undergraduate student wellness during a pandemic was scarce prior to the outbreak of COVID-19 and is still lacking. Studies investigating student wellness during pandemics often fracture the concept by quantitatively researching specific wellness dimensions (Cao et al., 2020; Galea et al., 2020; Tang et al., 2020) as opposed to exploring the construct from a holistic perspective. Additionally, few studies aim to understand how undergraduate students make meaning of wellness and their lived wellness experiences, specifically during a pandemic. Furthermore, emerging research (Huckins et al., 2020) corroborates the extant literature that posit student health behaviors were declining in …

Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi

Electronic Theses and Dissertations

Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.

Greek Life Membership As A Predictor Of Exercise Dependency, Taylor Novak Nygaard

Theses and Dissertations

Exercise is often regarded as a staple of a healthy lifestyle. Working out in excess, though, can easily become detrimental to an individual’s mental and physical wellbeing. Physical activity that is carried out in a compulsive and regimented manner, even when it may interfere with daily life or physical health, is referred to as exercise dependency. While not it’s own mental disorder, it has often been described as a secondary disorder in tandem with an eating disorder, and can be identified using the same criteria as one would use to diagnose Substance Use Disorder. The paradoxical nature of an addiction …

Association Between Childhood Obesity, Family Meals, And Dietary Quality Among Us Children Aged 6 To 17 Years Residing In Snap-Eligible Households, Noemi Rodriguez

Dissertations and Theses

Background:

Between 20 and 21% of US children 6-19 have obesity. Children residing in households eligible for the Supplemental Nutrition Assistance Program (SNAP) are exposed to vulnerable socioeconomic conditions, often living in low-resourced households and communities. These children are at a high risk for obesity, and thus to obesity-related comorbidities as well as adulthood obesity. The US Department of Agriculture (USDA) recommends family meals as well as diets meeting the American Dietary Guidelines as an obesity prevention strategy. These are connected; the dominantly theorized pathway by which family meals protect against childhood obesity is through the diet quality of the …

The Paiute, Water Wars, And A Covered Up Agricultural Revolution, Nicholas Anthony Chambers

History Senior Capstones

Like many other Native Americans, the Bishop Paiute in California have long faced an uphill battle in retaining their federally given land rights, access to natural resources, and their ability to remain self-sufficient. Often Native peoples (the Paiute included) have faced a long history of presidential administrations or federal agencies tolerating or even assisting them, only for a small political change to occur and all positive treaties or relations towards them evaporate or turn hostile. Tribes (according to American law) are supposed to be sovereign and see their treaties upheld in perpetuity. However, the Paiute (like many other Native tribes) …

Coming Full Circle On Human Rights In The Global Economy: International Economic Law Tools To Realize The Right To Development, Diane A. Desierto

Journal Articles

From the Article

This article argues that the discipline and profession of international economic law has undergone a significant architectural change to focus on human rights law as both the premise and promise of the international economic system. Contrary to prevailing currents that focus on the irrelevance of the global economic system to realize human rights, this article argues that international economic law tools have already been converging within the last decade to authentically realize the Right to Development of individuals, groups, and populations. The Draft Convention on the Right to Development defines the right as the enjoyment, participation, and …

Synergistic Effects Of A Domestic (Thiacloprid Based) Neonicotinoid Pesticide And Nitrogen, Phosphorus And Potassium Fertiliser On Common Earthworms (Lumbricus Terrestris)., Tristan Holmes

School of Biological and Marine Sciences Theses

Neonicotinoids are designed to target insect pests, but their extensive use and long persistence in soils mean that non-target soil organisms such as earthworms are likely to be chronically exposed to them. The common use of neonicotinoids in agricultural systems makes them highly likely to come into contact with other agro-chemicals that may give rise to synergistic effects. Chronic exposure of common earthworm (Lumbricus terrestris) to neonicotinoids in single or combined use with inorganic NPK fertiliser may pose problems that are not accounted for in most biological risk assessments under laboratory conditions. To assess the impacts of such chronic exposure …
