Ideological Extremism, Conspiratorial Thought, And Support For Authoritarianism In The United States, Sophie N. Martino

Honors Theses

Since the nation’s founding, Americans have tended to take democracy for granted. People see democracy as a given, believing that adherence to democratic values will persist. However, in the past few election cycles, there has been a trend in support for authoritarianism in the United States – not just with political leaders and figures, but also with individuals susceptible to authoritarian values and signals. This thesis seeks to address this apparent threat of authoritarianism in the United States, delving into possible factors that play a role in the growing support for authoritarian attitudes among Americans. I believe that two phenomena …

Hdl Cholesterol: Too Much Of A Good Thing? Cardiovascular, Elizabeth A. Moxley

Faculty Articles, Papers, and Other Scholarship

It is considered a well-established fact that high-density lipoprotein cholesterol (HDL-C) is a robust, inverse predictor of the risk of experiencing an atherosclerotic cardiovascular (ASCVD) event.[i] Whereas, low HDL-C characterizes an atherogenic dyslipidemia that reflects adverse lifestyle choices, impaired metabolism, and increased cardiovascular risk.[ii]

Hydraulic Redistribution Under Saline Conditions, Josh Gottlieb

Civil and Environmental Engineering Undergraduate Honors Theses

Water scarcity and soil salinity are dual stressors for plants in arid, salt-affected ecosystems. Hydraulic redistribution, a hydraulic adaptation which moves water through plant roots into dry or saline soil regions along potential gradients, aids plant survival in stressful environments. Recent theory regarding hydraulic redistribution proposes limitations on the process within saline soils. This study applies a minimalist resistor-capacitor model of the soil-plant-atmosphere system to the experimental conditions of a 2010 study investigating hydraulic redistribution in a salt affected area. The effectiveness of the model is evaluated, and a sensitivity analysis is conducted to identify key dynamics affecting the moisture …

Alterations In The Oral Microbiome Leading To Inflammatory Periodontal Disease, Emma Vlaun

Honors Scholar Theses

The oral cavity contains a complex micro-ecosystem of flora inhabiting a variety of different niches. Some of these niches include saliva, shedding surfaces, and non-shedding surfaces. Biofilms in the oral microbiome, colloquially referred to as dental plaque, can accumulate on non-shedding surfaces, such as natural teeth and other artificial hard parts such as braces, dentures, fillings, and implants. These biofilms are made up of many mutualistic bacteria that stick to each other and adhere to hard surfaces. Scientists speculate that at least 700 different species of bacteria inhabit various parts of the mouth. These bacteria occupy different niches in varying …

Photocatalytic Anti-Markovnikov Hydroetherification Of Olefins, Kimberly A. Loyer

Undergraduate Honors Theses

The development of olefin hydroetherification reactions via the addition of an alcohol nucleophile and hydrogen atom across an unsaturated carbon-carbon bond has remained a sought- after synthetic transformation. The formation of ethers via this methodology has traditionally required the use of transition metals and/or harsh conditions to catalyze the reaction and is challenging to make selective. However, the Nicewicz laboratory has since developed an anti- Markovnikov intramolecular hydroetherification of alkenols using photoredox catalysis. With the mechanism of this pivotal transformation—and of photoredox reactions in general—being largely unexplored mechanistically, the Hirschi lab implemented experimental 13C kinetic isotope effects (KIEs) and density …
