Influence Of Row Pattern And Prohexadione Calcium On Peanut (Arachis Hypogaea L.) Maturity And Profitability, Samantha N. Mehl

All Theses

Many newer peanut cultivars offer yield benefits but have larger canopies and are taking 10 or more days longer to reach desired maturity levels. Prohexadione calcium (PC) and twin row planting pattern have been reported to increase the amount of orange, brown or black pods compared to their respective alternatives. Four cultivars were selected and studied based on frequency of use in South Carolina then paired into an earlier maturing group that reached optimal maturity at 135 to 140 days after planting, and a later maturing group that reached optimal maturity at 150 or more days after planting.

Interactions Between High-Pressure Processing And Natural Antimicrobials In Ground White-Meat Chicken: An Analysis Of Microbial, Textural Charactheristics And Physicochemical Changes, Amalia M. Diaz Alejandro

All Theses

High Pressure processing is an innovative technique for preserving a wide variety of foods, including meat, and this method is increasingly used to satisfy consumer demand for quality food products. High-pressure treatment can impact, negatively or positively, various aspects of meat quality, including color, texture, protein denaturation, and microbial stability, particularly when food products are processed at ambient or low temperatures. By minimizing thermal exposure, appropriate high-pressure ranges help to prevent quality and nutrition degradation, reduce microbial contamination, and enhance tenderness.

The first objective of this research was to examine the influence of high-pressure processing and addition of natural antimicrobials …

Regulation Of Serpina1 Mrna Expression By Environmental Conditions In Hepatocyte Cells, Fnu Jiamutai

All Theses

The SERPINA1 gene encodes the critical protease inhibitor α-1-antitrypsin (A1AT). A1AT represses neutrophil elastase activity to protect lung tissue from inflammatory damage. A deficiency in α-1-antitrypsin can lead to chronic obstructive pulmonary disease (COPD). Pathogenic genetic variants in SERPINA1 are also associated with A1AT protein misfolding and liver cirrhosis. The regulatory mechanisms of SERPINA1 expression are not well understood, but previous studies suggest that alternative polyadenylation in the 3' untranslated region (3'UTR) affects A1AT protein expression. In this study, we used the liver cancer cell line HepG2 to determine how environmental conditions influence SERPINA1 mRNA expression and post-transcriptional regulation. We …

A Benchtop Analysis Of Pressure Offloading Associated With Custom Socket Inlays In Transtibial Prostheses, Sarah G. Hill

All Theses

Approximately 78% of people with lower limb amputations are dissatisfied with the comfort of their prostheses (Quintero-Quiroz & Perez 2019). In the case of lower limb amputations, the residual limb tissue bears far more weight than it was before the amputation. The pressure put on the soft tissue of the residual limb causes discomfort (Brown et al. 2021). In previous work, custom inlays were created, which fit inside the prosthesis and offload pressure, with the goal of helping to increase the comfort and satisfaction of the prosthesis user (Brown et al. 2021). In this project, a benchtop prosthetic socket loading …

When Hedge Funds Move In: Socioeconomic Consequences Of Single-Family Rentals, Hannah Misurati

All Theses

In this thesis I explore the effect of increased investment in the single-family rental sector on inequality and housing affordability. I measure the effect of the single family rental (SFR) share on Gini indices and median rental prices across the largest U.S. cities. I construct three non lagged and three lagged models for each of the two dependent variables. In my analysis of the relationship between SFR shares and inequality, I do not find a significant relationship after accounting for potential reverse causality. However, the relationship between SFR shares and rent prices is shown to be negative and significant once …

Impact Of Nitrogen Species On Algal Carbon Capture, Lauren J. Todd

Estimating The Effect Of Nuclear Energy On A Country's Electricity Generation Mix: Fukushima As A Case Study, Sarah Elizabeth Zarrilli

All Theses

In this paper, I attempt to estimate the true effects of removing nuclear energy on a country’s energy portfolio, particularly how the country substitutes to other fuel sources for electricity generation and how it impacts the country’s marginal electricity prices. In 2011, anti-nuclear sentiment that arose in Japan following the meltdown of the Fukushima prefecture’s nuclear power plant resulted in the country decreasing its nuclear electricity generation from over 30% of its total supply to 0% in under two years. I use the dramatic variation across Japan’s electricity supply regions over the denuclearization period to attempt to estimate the true …

Silence In Stem? The Impact Of Experienced Social Identity Threats On Women, Madison Brumbaugh

All Theses

Despite making up a similar proportion of the workforce, women are grossly underrepresented in STEM occupations compared to men (65% vs. 35%). Prior research suggests that women’s underrepresentation in STEM results in negative consequences, such as increased psychological burnout and decreased work engagement (Hall et al., 2015; Hall et al., 2018), through the mechanism of social identity threat. Academics have yet to explore how experiencing social identity threat impacts silence behaviors for underrepresented women in STEM. Building off social identity theory and prior research on social identity threat, the current study sought to compare women working in STEM occupations who …

The Multi-Trophic Effects Of Buckthorn Removal, Amanda Jacobs

Great Lakes Center Masters Theses

European buckthorn (Rhamnus cathartica) is a non-native woody plant in North America that often grows in dense, monotypic stands, frequently displacing native plants and reducing species richness of invaded native communities. Given that plants are basal in most food webs, the homogenization of plant communities might be expected to cascade into homogenization at higher trophic levels (Hunter and Price, 1992). I investigated the multi-trophic effects of buckthorn removal at three levels: (1) ‘native,’ in which there were no buckthorn trees or shrubs, (2) ‘buckthorn trees,’ in which buckthorn was not removed and grew into spaced mature trees, and …

Empowering Speech By Moderating It, Danielle Keats Citron, Jonathon W. Penney

Articles & Book Chapters

Content moderation is typically viewed as an affront to free expression. When companies remove online abuse, they face accusations of censorship. Lost in the discussion is the fact that victims of intimate privacy violations and cyberstalking typically-and regrettably-withdraw from on- and offline activities. Online assaults chase targeted individuals offline; they silence victims. Content moderation can secure opportunities for people to speak. Legal and corporate prohibitions against intimate privacy violations and cyberstalking can help provide the reassurance that victims need to stay online. They can endow individuals with a sense of trust so they continue to use networked technologies to express …
