Reports Of Autosomal Recessive Disease And Consanguineous Mating Within The Human Population, Johnathon L. Schluter

Master's Theses

It is anecdotally evident when investigating published reports of autosomal recessive disease that a substantial number of cases are the result of related (consanguineous) mating. This research seeks to quantify the percent of manuscripts describing autosomal recessive diseases published between 2000 and 2020 in which consanguineous mating is indicated. We analyzed 602 peer-reviewed manuscripts to identify the percentage of cases presented in which consanguineous mating was indicated, the underlying genes (novel gene or new mutation) and geographical region. These papers were accessed through a specific set of parameters on the free access PubMed Central (PMC) database. A total of 552 …

On The T-Degree Of Anderson Thakur Polynomials In The Case Of Fields Of Order P Where P Is A Prime, Joshua Bush

Master's Theses

The Anderson Thakur polynomials are of great interest in the investigation of zeta values. Here, we address the question of their degree in finite fields of the form Fp. We define a graph that is closely connected to Anderson Thakur polynomials and which represents a polynomial we denote as Anxn−1. Collections of terms of this polynomial are equating with the vertices of the graph and are vanishing or nonvanishing. The vanishing structure of the graph is analyzed and we conclude with a simple degree formula.

Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason

Master's Theses

The increase in mercury production through anthropogenic activities has led to a global crisis of mercury pollution that poses a significant threat to the health of both humans and wildlife. Aquatic ecosystems are especially at risk due to the creation of methylmercury, a toxic form of mercury, by sulfate-reducing bacteria in anoxic sediments and soils. Methylmercury enters the food chain where it bioaccumulates in individual organisms and then biomagnified with increasing trophic level. Aquatic birds are useful bioindicators of many pollutants, including mercury, due to their abundance and position in the food chain. Previous studies have primarily focused on mercury …

The design of this experiment attempts to derive the intent-to-treat (ITT) effect stemming from the provision of glasses to coffee harvesters in Guatemala. Methodology incorporates two distinct approaches: an ANCOVA model with basic controls and a fixed effects model with a control for farm-specific harvest trends. With daily harvest weight observations serving as a proxy for productivity, and a sample of 321 participants …

What The Stork Brought: Endogenous Fertility Preferences, Lucas Fortier Borden

Master's Theses

Where most existing literature on fertility preferences has described how fertility preferences shape outcomes, this paper provides insight into how the sex of a recent birth affects a mother’s fertility preferences. Utilizing data from the Demographic Health Survey from 1985-2020 in 81 countries containing 309,238 mothers who gave birth in the past 12 months and who have equal to or fewer than three children, I employ OLS with two-way fixed effects as my primary specification, examining the effects of the plausibly exogenous sex of a recent birth on sibship sex composition preferences. Results show that a recent daughter birth increases …

Does Trust Influence Being Generous? An Empirical Study Across Five Countries, Andrew Hall

Master's Theses

This study examines whether social trust, a key aspect of social capital, influences individual generosity behaviors. Previous research has explored the relationship between social capital and philanthropic actions, but comprehensive analyses remain sparse. To address this gap, we employed a dictator game together with trust-related survey questions, collecting data from participants across five countries globally. We categorized trust into four distinct areas: social trust, ingroup trust, outgroup trust, and general trust. Similarly, we divided our dependent variable, generosity, into two types: costly generous and costless generous behaviors. Our findings were mixed and varied by location. Overall, general trust positively influenced …

Exploring The Learning Outcome Of A Financial Literacy Game, Stanley Yip

Master's Theses

The financial literacy game was part of a financial literacy intervention that was conducted in Karnataka, India. Rural women participated in playing the game for four weeks. Using a fixed effects model at the subject level, the game was measured by three outcomes. These outcomes consist of the rate of type one errors, type two errors and the rate of going bankrupt that could occur for players when playing the financial literacy game. With type one errors, we find that adding one more unit on the return on investment (roi) would lead to about a 1.59 percent decrease in type …

Financial Literacy And Aspirations: Experimental Evidence From Eastern Uganda, Ester Agasha

Master's Theses

Financial literacy and the cultivation of aspirations are pivotal in empowering individuals and fostering economic growth, particularly within disadvantaged com munities. Although prior research has extensively analyzed the individual effects of financial education and motivational interventions on economic behaviors, there is less clarity on how the synergy between them can collectively impact the socioe conomic status of individuals in developing economies, especially women. Through randomized control experiment(RCT), this study explored the effectiveness of two interventions; 1) a financial literacy digital gaming application and, 2) an aspirations intervention (a short video documentary and a follow-up curriculum) in not only enhancing financial …

Heat And Social Behavior: The Effect Of Personal And Social Well-Being, Antonia Michele Sottile

Master's Theses

High temperatures have the capacity to cause catastrophic changes in social and economic systems, but does heat impact our social behavior, and is this potential effect moderated by a person's social and personal well-being? In this paper, I utilize data from a 5 country laboratory experiment and run a fixed effect regression model to understand the role of these metrics in determining behavioral outcomes. The results suggest that heat alone has no impact on egalitarianism, generosity, or selfishness, but that it does have a small negative impact on spite. Stress was also found to have a negative impact on spite, …

Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez

Master's Theses

Urbanization is an example of human induced rapid environmental change that can have wide-reaching ecological effects, including habitat destruction, fragmentation, and alteration of local climates. Effects of urbanization have been shown to impact wildlife, as disturbances resulting from urbanization can create novel environments and selective pressures that could lead to changes in morphology, physiology, or both. Small mammals such as rodents are an ecologically important set of wildlife species because they are a key prey item for several predators, hold strong influence over plants as a primary consumer, and some species carry and transmit major human and animal diseases. Previous …

Chemical Extraction Of Non-Exchangeable Radiocesium From Fukushima Soils Using Ion-Exchange And Selective Precipitation, Ian Danquah
