Investigation Of Experimental Variation Of Bovine Sphingomyelin As A Novel Ingredient For Ultraviolet Protection, Esther Chen

Master's Theses

Skin cancer is a prevalent disease that globally affects 2-3 million people per year [1]. This number is expected to grow tenfold as depletion of the ozone layer contributes to harsher rays reaching Earth’s surface [2]. A common way to protect against those ultraviolet waves is to apply sunscreen, however, recent reports call into question the safety of some active ingredients as they can enter through the skin into the bloodstream [3]. This thesis aims to investigate an alternative solution that uses bovine sphingomyelin (BSM) as photoprotective solution against UV irradiation.

In order to evaluate the effectiveness of BSM against …

The Strawberry Rhizosphere Microbiome: Role On Plant Health And Nutrition, Eric Michael Boyd

Master's Theses

Microbial-root associations are important to help plants cope with abiotic and biotic stressors. Managing these interactions offers an opportunity for improving the efficiency and sustainability of agricultural production. By characterizing the bacterial and archaeal community (via 16S rRNA sequencing) associated with the bulk and rhizosphere soil of sixteen strawberry cultivars in two controlled field studies, we explored the relationships between the soil microbiome and plant resistance to two soilborne fungal pathogens of strawberry (Verticillium dahliae and Macrophomina phaseolina). Overall, the plants had a distinctive rhizosphere microbiome relative to the bulk soil, with higher abundances of known beneficial bacteria …

Planning For Pollinators, Encouraging Biodiversity For Agriculture Resiliency, Sebastian Brian Cardoza

Master's Theses

Pollinators are essential to food production globally. Without them, the production of food becomes increasingly difficult, time consuming, and costly. Unfortunately, due to the rapid changes to our earth's physical and climatic structure millions of species are becoming classified as threatened, endangered or extinct. Among these declining species are pollinating insects such as Aphis mellifera (honeybee) and other native species. This is due to a phenomenon known as colony collapse disorder (CCD) and other native bees. The decline indicates that the future habitability of earth may be in jeopardy. The solution to this crisis is to expand the habitat of …

Reduction Of Fat Content In Processed Meats Using Hot-Boning And Cold-Batter Mincing Technology, Morgan P. Wonderly

Master's Theses

Processed meats have received negative publicity due to high fat contents that have been linked to adverse effects on human health. Fat is an essential ingredient in many processed meat products, so reducing this all while maintaining the desired characteristics of the product is a challenge. The purpose of this study was to generate low-fat meat products using a combination of hot-boning/crust-freeze-air-chilling (HB-CFAC) and cold-batter mincing (CBM) technologies. Pork hams were subjected to HB-CFAC or chill-boning/crust-freeze-air-chilling (CB-CFAC) prior to 3 min pre-mincing and 6 min mincing for control gels with back-fat addition or low-fat gels with water addition instead of …

Wearable Heart Sound And Ekg Recorder, Grace R. Larson

Master's Theses

Acute congestive heart failure is a leading cause of morbidity and mortality. Patients often undergo repeated hospitalizations with an annual cost in excess of $32B dollars. Early detection of impending acute congestion allows for pharmaceutical interdiction that prevents hospitalization, improves outcomes, and reduces healthcare spending. A subcutaneous implantable monitoring device that detects impending acute congestive heart failure by using heart sounds may provide a valuable tool that can be used to titrate heart failure medications to prevent acute heart failure requiring hospitalization. The device may be used to measure changes in the intervals between the R-wave and S1 and S2 …

The Effects Of A Baseball Season On Various Body Composition Measurements And Assessment Of Dietary Intake In Ncaa Di Baseball Players, Jordan Marthens

Currently, little research exists on garden education’s influence on students’ environmental literacy, especially in underrepresented communities. Using a nonequivalent control group study design, this project investigated the impact of a garden education program in Central San José, CA in an …

Evaluation Of Silica Hydride Based Amide Stationary Phase For High Performance Liquid Chromatography And Aqueous Normal Phase Separations, Emma Tardiff

Master's Theses

With many modern chromatographic advancements, silica hydride based columns (also known commercially as Type-C) represent yet another evolutionary step in stationary phase development. Type-C silica hydride columns have the ability to retain both polar and nonpolar analytes and have the ability to behave in either RP or ANP modes of separation depending on mobile phase composition. A consequence of this increased stability is that Type-C columns can be used over a wide range of mobile phase compositions, from purely aqueous to purely nonpolar organic solvents, and any combination of the two. While the retention behavior of Type-C columns depends highly …

Using Stable Isotopes To Determine Foraging Areas Of Leatherback Sea Turtles: Limitations Of The Isotope Tracking Technique In The Western Atlantic Ocean, Sharon Hsu

Master's Theses

Reproductive output has long been linked to habitat quality and resource availability. Individuals foraging in high-quality habitats with high resource availability will have better body conditions and higher survival rates, as well as greater reproductive output. Post-nesting, Western Caribbean leatherback turtles are known to migrate to at least two foraging regions: the western North Atlantic and Gulf of Mexico. This study had three objectives: [1] measure δ13C and δ15N values in bulk skin tissue of females nesting in Parismina, Costa Rica to reveal prior foraging region; [2] assess influence of foraging region on female body size and reproductive output; and …

Changing Tides: The Impact Of Chinese Investment In Gambia’S Fishing Industry, Abdallah Alami

Master's Theses

This thesis analyzes the presence and impact of Chinese fishing companies in the West African country of The Gambia. The presence of the Chinese companies have resulted in drastic changes in the country’s fisheries industry where they have a comparative advantage due to their geographic location. Through interviews conducted with Gambian officials in the Ministry of Fisheries and Water Resources, and members of the fishing community (both fishermen and merchants), I conclude that the Chinese presence is a trade-off between the Gambian government and the Chinese investors. It is positive because they are engaged in a beneficial partnership with the …

Master's Theses

The purpose of this study is to examine the efficacy of city policies undertaking public goods investments to benefit disadvantaged communities in San Francisco. Namely, is the process of improving the quality of public goods serving targeted populations, or does it lead to unintended consequences such as gentrification? I take advantage of the timing of city recreation center renovations and the synthetic control method to capture any difference in the proportion of users that is poor before and after the renovation date. I use San Francisco Recreation and Park Department registrant data containing user zip codes and census demographic data …

The Role Of High-Fructose Corn Syrup Imports In Child And Women Obesity, Anna Subirana Bofill

Master's Theses

High Fructose Corn Syrup is believed to be responsible for the increase of the obesity epidemic that is affecting both developed and developing countries, yet to date there are no rigorous analyses that quantify this effect. To estimate the impact of consumption of HFCS on obesity, I have paired country-specific data on imports of HFCS from the United Nations International Trade Statistics Database (UN Comtrade) with women and child health data from around 70 countries from 1985 to 2018. The results show that conditional on space and time fixed effects, imports of HFCS with a high concentration of fructose have …

The Effect Of Sex Of Firstborn Children On Attitudes Towards Intimate Partner Violence, Shuvam Rizal

Master's Theses

What are the different ways in which one’s life is influenced by the sex of their children? Is there an effect on how they view Intimate Partner Violence? If so, is there a difference in how the male parent is affected by the sex of his child than the female parent? Bodies of conflicting Social Sciences literature suggest having a daughter makes one both more and less likely to engage in Intimate Partner Violence. In this paper, I approach this question through the use of a Linear Probability Fixed-Effects model on Demographic Health Surveys (DHS) datasets, using data from the …

Green Gold: Avocado Price Shocks And Violence In Mexico, Katie Roett

Master's Theses

The role of economic incentives in political armed conflict is well documented, but there is very little evidence on a growing and increasingly globalized form of violence: organized crime. Most existing research focuses on the impact of price shocks on wages and how this affects an individual’s opportunity cost to join an armed group or political movement. However, unlike other violent groups, organized criminal groups do not compete for political power, but profits in illegal markets. In Mexico, these groups have more than doubled in the past two decades, leading to an explosion of violence and record high 35,000 people …

Estimating Treatment Effect Heterogeneity In A Comprehensive Microenterprise Intervention, Mary Gathungu

Master's Theses

Do cash transfer programs have heterogeneous treatment effects within the treatment group? Why do some households in these interventions seem to benefit more than others? What is the overall treatment effect of the Microenterprise Intervention? I address these questions through the study of a comprehensive microenterprise intervention program carried out in Kenya, Africa by a non-profit organization called the Village Enterprise Organization and I obtain economic outcome data from a randomized control trial that gives out conditional cash transfer that is conditional on business formation. The Microenterprise Intervention combines cash grants and mentorship and training to achieve long term economic …

The Harms Of Willful Ignorance: Maternal Healthcare Providers’ Insight On Racial Disparities, Cara Marisa Cancelmo

Master's Theses

Black women in the United States die in pregnancy and childbirth at alarmingly high rates. According to The Center for Disease Control, black women are two to three times more likely to die from pregnancy-related causes than white women. The black-white racial disparity is even greater in New York City, and The NYC Department of Health has found that black mothers in NYC still face higher rates of harm even when accounting for risk factors like educational attainment, obesity, and neighborhood poverty level. Drawing on 18 interviews with NYC-based Obstetricians, Labor and Delivery Nurses, and Midwives, this study examines how …

Altered Gene Expression In Circulating Immune Cells Following A 24-Hour Passive Dehydration, Aidan Fiol

Master's Theses

Dehydration has many deleterious effects ranging from impaired cognitive function to decreased aerobic performance. This study evaluated the effects of a mild, passive dehydration on the transcriptional responses of circulating immune cells. We pursued research questions about how whole-body dehydration and small changes in plasma osmolality may affect the greater concept of immune resiliency or susceptibility to infection through acute gene expression changes that may persist during chronic stress. Our approach was to precisely quantify hypertonicity experienced by circulating peripheral blood mononuclear cells and neutrophils and quantify transcriptomic changes in cell lysates using RNAseq. RNAseq revealed 373 total genes changing …

Household Food Security Status, Dietary Patterns And Diabetes Risk (Hemoglobin A1c) Among Cambodian Refugees With Depression, Shanjida Jui

Master's Theses

Background

Cambodian refugees who experienced famine and trauma from the Khmer Rouge genocide are disproportionately at high risk of type 2 diabetes. This risk is exacerbated when this vulnerable population experiences a high prevalence of food insecurity upon resettlement in the U.S. As a result, refugee dietary intake and nutrition uniquely contribute to the rise of often long-term health consequences and pose an unexpected burden on the U.S. healthcare system.

Objectives

(1) To describe household food security status of Cambodians refugees (2) To examine the association between food security status and socioeconomic status (SES) of Cambodian refugees; (3) To describe …

Pre-Surgery Leptin Level And Weight Loss In Female Bariatric Surgery Patients, Miriam Katz

Master's Theses

Background: Improving weight loss after bariatric surgery remains a clinical concern. An unstudied factor is the role of leptin, the appetite control hormone, as a pre-surgical predictor of weight loss. High serum levels, often seen in obesity, are an indicator of leptin resistance as the brain no longer responds to satiety signaling.

Methods: Leptin levels were ascertained in female bariatric patients (n=28) prior to surgery at a large tertiary care hospital. We calculated Pearson Correlation Coefficients (r) and unstandardized β coefficients using multivariate linear regression. Primary outcome: Percent Excess Weight Loss (%EWL) evaluated at 6- and 12-months post-surgery. …

The Relationship Between Sport Commitment With Off-Season Training Time And Previous In-Season Playing Time In College-Aged Soccer Players 2020., Luke Zuber

Master's Theses

Sport commitment is defined as “…the desire and resolve to continue sport participation” (Scanlan, Carpenter, Schmidt, Simons, & Keeler, 1993, p. 6). Since the first definition, the concept has been further refined to reflect a more multidimensional paradigm. Overall, sport commitment is thought to be comprised of the dimensions of enthusiastic commitment and constrained commitment (Scanlan, Chow, Sousa, Scanlan, & Knifsend, 2016). Those constructs can be broken down further to 12 subconstructs that are represented in the Sport Commitment – 2 (SC; Scanlan, Chow, Sousa, Scanlan, & Knifsend, 2016), in order to evaluate the source and level of an individual’s …

Mindful Eating Behavior In Post Surgical Bariatric Patients, Megan Mabery Filer

Master's Theses

Emotional eating and binge-eating behavior in obese individuals and post-surgical bariatric patients are both linked to decreased ability to identify and cope with stress (Mitchell et al., 2016; Urquhart & Mihalynuk, 2011). In turn, obese patients who exhibit greater rates of stress-eating behavior show reductions in levels of mindfulness (Ouwens et al., 2015). The purpose of the study was to investigate the association between mindful eating component scores and selected weight loss outcomes in post-surgical bariatric patients.

Patients from a private bariatric clinic in Shreveport, Louisiana who underwent gastric sleeve or gastric bypass were invited to participate based on specific …
