Genetic Determinants Of Variation In The Gh/Igf-1 Axis And Their Relationship To Cardiometabolic Health, Rafael Luis Aguirre Guillen

Theses and Dissertations

Background: In a study of Mexican Americans, we performed analyses of GEI and pleiotropy in the axis in relation to MS. GH/IGF-1 axis components were studied. Model parameters and likelihoods were estimated by maximum likelihood.

Results: Pleiotropy was observed for IGFBP3 (p

Conclusions: IGF-I and IGFBP3 are genetically correlated with MS whereas MS influences the additive genetic variance in IGFBP1 variables mainly but also in IGF-I somewhat by virtue of the VH exhibited by IGF-I/IGFBP1.

Association Between Lifetime Adverse Events, Emotion Dysregulation, Posttraumatic Stress Symptoms, Acculturation, And Chronic Pain: A Moderated Mediation Model, Miriam El-Haj

Theses and Dissertations

The association between traumatic experiences and chronic pain is well established. Lesser is known about how acculturation might affect this relation, specifically with Hispanics. In the present study, self-report measures on traumatic experiences, posttraumatic stress symptoms, emotion dysregulation, chronic pain, and acculturation were administered to 140 participants (71.4% females) aged 18–65 years old (M = 35.06, SD = 11.55), to determine whether acculturation moderates the relation between adverse lifetime experiences and chronic pain as mediated by posttraumatic stress symptoms and emotion dysregulation.

Those who were highly acculturated to the U.S. Anglo culture were higher on chronic pain than those who …

Comparison Of Rl Algorithms For Learning To Learn Problems, Adolfo Gonzalez Iii

Theses and Dissertations

Machine learning has been applied to many different problems successfully due to the expressiveness of neural networks and simplicity of first order optimization algorithms. The latter being a vital piece needed for training large neural networks efficiently. Many of these algorithms were produced with behavior produced by experiments and intuition. An interesting question that comes to mind is that rather than observing and then designing algorithms with beneficial behaviors, can these algorithms be learned through a reinforcement learning by modeling optimization as a game. This paper explores several reinforcement learning algorithms which are applied to learn policies suited for optimization.

A Better Kind Of Frozen Food: Using State And Federal Law To Bring School Farming And Other Community Agriculture To Rural Alaska Communities, Charles Kidd

Alaska Law Review

Despite a seeming abundance of nourishment in the state, with folklore of Alaska rivers so full of salmon that one can walk across to the opposite shore without getting one’s feet wet, Alaska is a very food-insecure state. As of 2014, 15% of Alaskans were found to be food insecure. This rate is part of an increasing trend; from 1998 to 2007, food insecurity increased to 3.7% in Alaska, the largest increase in the country. Further, because only 5% of the food consumed in Alaska is actually produced in-state, there is typically only a three to five-day supply of food …

Climate Change And Big Business: The Endless Cycle, Angela Steele

Capstone Projects and Master's Theses

Climate change, as it stands, is a large topic. As it relates to business, it grows exponentially, yet relates to every single one of us. Before the nineteenth century, climate cycles were mostly naturally occurring. Unfortunately, in recent years anthropogenic (human) causes have been introduced. The largest problem is carbon dioxide, which is produced from numerous human activities but largely from the burning of fossil fuels, and leads to massive warming effects on our planet. That’s where business comes in: companies, such as those within the agriculture, fossil fuel, and sunscreen industries, seek multi-million dollar profits off of the warming …

Publications

Gallus gallus (chicken) is phenotypically diverse, with over 60 recognized breeds, among the myriad species within the Aves lineage. Domestic chickens have been under artificial selection by humans for thousands of years for agricultural purposes. The North American Araucana (NAA) breed arose as a cross between the Chilean “Collonocas” that laid blue eggs and was rumpless and the “Quetros” that had unusual tufts but with tail. NAAs were introduced from South America in the 1940s and have been kept as show birds by enthusiasts since then due to several distinctive traits: laying eggs with blue eggshells, characteristic ear-tufts, a pea …

Gluten Detection Methods And Their Critical Role In Assuring Safe Diets For Celiac Patients, Claudia E. Osorio, Jaime H. Mejias, Sachin Rustgi

Publications

Celiac disease, wheat sensitivity, and allergy represent three different reactions, which may occur in genetically predisposed individuals on the ingestion of wheat and derived products with various manifestations. Improvements in the disease diagnostics and understanding of disease etiology unveiled that these disorders are widespread around the globe affecting about 7% of the population. The only known treatment so far is a life-long gluten-free diet, which is almost impossible to follow because of the contamination of allegedly “gluten-free” products. Accidental contamination of inherently gluten-free products could take place at any level from field to shelf because of the ubiquity of these …

The Training Of A Para Powerlifter: A Case Study Of Adaptive Monitoring, Training And Overcoming, Derek Wilcox

Electronic Theses and Dissertations

Paralympic athletes (PA) appear to be more prone to chronic overuse injuries from daily wheelchair or crutch use. Over half of these injuries are shoulder related which can deleteriously impact quality of life. Adaptive powerlifters (AP) are a subdivision of Paralympic athletes and are at a higher risk for catastrophic injuries as compared to their counterparts, due to the compound of fatigue and lifting of maximal weights. For this reason, it is vital to have well-designed training plans for these athletes in order to preserve quality of life and maximize performance in competition. Unfortunately, there is a lack of literature …

The Gendering Of Death Personifications In Literary Modernism: The Femme Fatale Symbol From Baudelaire To Barnes, Amanda Mcnally

Electronic Theses and Dissertations

The time of modernity, defined here as 1850-1940, contributed to massive changes in the representation of the feminine in literature. Societal paradigm shifts due to industrialism, advances in science, psychology, and a newfound push for gender equality brought transformation to the Western World. As a result of this, male frustrations revived the ancient trope of the femme fatale, but the modern woman—already hungry for agency, tired of maligned representation in heinous portrayals of skeletons, sirens, and beasts—saw a symbol begging for redemption rather than the intended insult. Women of the nineteenth century infused texture to a two-dimensional accusation that argued …
