Examination Of Model Minority Myth, Mentorship, University Environment, And Sense Of Belonging On The Well-Being Of Asian American Undergraduate And Graduate Students., Stephanie Chin, Stephanie Chin

Electronic Theses and Dissertations

Even though Asian Americans continue to demonstrate academic excellence and have the highest rates of completion in higher education, their psychological well-being and the factors impacting it are often overlooked due to the model minority myth (Poon et al., 2016; Mahalingham, 2013). Higher education research mainly focuses on academic outcomes (e.g., persistence and retention) and less so on psychological outcomes. This study explored and examined psychosociocultural factors, specifically internalization of the model minority myth stereotype, mentorship, university environment, and sense of belonging on psychological (eudaimonic) well-being, in order to provide a more holistic and contextualized perspective of Asian American students’ …

The Architect Of The Past: Heinrich Himmler's Remaking Of Germany's History., Chad M. White

Electronic Theses and Dissertations

This thesis explores the complex interplay between historical narratives, ideological manipulation, and cultural artifacts in Heinrich Himmler’s efforts to reshape Germany’s history during the Nazi regime. The study shows how Himmler used historical revisionism to mythologize Germanic history to support Nazi ideology. Himmler used the Ahnenerbe, an SS organization, to research and propagate distorted narratives, fabricating artifacts to legitimize the Aryan myth and assert Germanic superiority. Influenced by movements like the Völkisch Movement, Himmler's ideology relied on pseudo-historical narratives to shape public perception and Nazi policies. The study analyzes Himmler's writings and the spatial transformation of sites like Wewelsburg Castle …

Effects Of A Protection Zone In A Reaction-Diffusion Model With Shifting Bounded Habitat And Allee Effect., Davis Henderson

Electronic Theses and Dissertations

We consider a reaction-diffusion equation that models a population in a shifting bounded habitat with a protection zone and the Allee effect. We assume that the population growth function exhibits the strong Allee effect and has a positive integral within the protection zone (indicating population persistence) and a negative integral in the surrounding patches (indicating population decay). We prove that the existence of steady-state solutions to this system depends on the length of the protection zone. It is demonstrated that there exists some value H* such that, for a protection zone of size H*, there exists a solution and, for …

Carboxen Micropreconcentrator Performance For Analyzing Btex In Air., Raymond Daniel Spargo

Electronic Theses and Dissertations

Volatile Organic Compounds (VOCs) are a class of toxic chemicals in environmental air associated with several serious health risks. Some of the most common and concerning VOCs are Benzene, Toluene, Ethyl Benzene, and Xylene (BTEX). To maintain healthy air quality in these environments, researchers pursue instruments and processes to quickly and accurately predict sub-ppb concentrations of BTEX in indoor and outdoor air. By employing a micropreconcentrator (μPC) to combine Solid-Phase Micro-Extraction (SPME) with Gas Chromatography Mass Spectrometry (GC-MS) analysis, trace BTEX content in air samples can be captured, extracted and analyzed. In this thesis, a dual-compartment μPC with Carboxen 1000 …

Relation Between The Negative Cognitive Triad, Perceived Everyday Discrimination, Depressive Symptoms, And Tnf-A In Adolescents., Ashley Ann Marshall Dondanville

Electronic Theses and Dissertations

This study is based on Beck's cognitive stress-vulnerability model of depression and previous research on (a) the increased risk for severe illnesses associated with TNF-⍺ (i.e., an inflammatory cytokine), (b) the effect of perceived everyday discrimination (PED) on depressive symptoms and TNF-⍺, (c) the association between depressive symptoms and TNF-⍺, (d) and findings that the negative cognitive triad (i.e., negative views of the self, world, and future) serves as a partial mediator between PED and depressive symptoms. The purpose of this study is to integrate Beck’s model and these different research lines by inspecting the associations between the stressor PED …

Relations Between Discrimination, Negative Attribution Style, Cortisol, And Depressive Symptoms In Adolescents., Hannah Widmer

Electronic Theses and Dissertations

The aim of our study was to integrate the chronic stressor of Perceived Everyday Discrimination (PED) into the Hopelessness Theory of Depression with a focus on the comorbidity between physical and mental health by way of depressive symptoms and cortisol in adolescents. Research has shown that cognitive diatheses mediate the relation between stress and depressive symptoms and cortisol predicts depression. We hypothesized that Negative Attribution Style (NAS) and cortisol would mediate the relation between PED and depressive symptoms. Altogether, 99 adolescents (mean age: 14.10 years, 36.4% female; 63.6% male; ethnicity: 2% Latinx; 98.2 % non-Latinx; race: 41.4% Black, 34.8% White, …

All Graduate Theses and Dissertations, Fall 2023 to Present

The goal of this thesis is to provide greater resolution on the age and character of the subglacial sediment recovered from the base of the Camp Century ice core, northwestern Greenland. Geochemical analysis indicated that the upper sub-ice sediments were geochemically different and experienced greater weathering than the basal unit underlying a one-meter silty ice lens. Analysis of feldspars within the very fine sand fraction indicates they are dominated by potassium feldspar. Sediment was dated using luminescence, which provides an age for the last time sediment was exposed to light. Luminescence analysis returned ages around 420 thousand years old, which …

Citizen Science Project On Urban Canids Provides Different Results From Camera Traps But Generates Interest And Revenue, Neville F. Taraporevala

All Graduate Theses and Dissertations, Fall 2023 to Present

As more people live in cities, wildlife increasingly encounters people. Coyotes (Canis latrans) and red foxes (Vulpes vulpes) are two carnivores that have easily adapted to urban environments causing them to come into conflict with people and their pets. Citizen science, where members of the community aid scientists in the collection of data, has emerged as a low-cost method of studying these species that can provide benefits to management agencies but may provide different results than traditional methods. We analyzed data collected by citizen scientists and data collected via motion-triggered camera traps to see how each …

Invasion Potential Of Nonnative Fishes Through A Large Western Dam Into A Prized And Vulnerable Ecosystem, Barrett T. Friesen

All Graduate Theses and Dissertations, Fall 2023 to Present

Native river fish face threats from habitat fragmentation, water overallocation, invasive species establishment, and powerful synergies amongst these factors. In the Colorado River Basin, USA, these threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by nonnative fish species. There is widespread concern low water level in Lake Powell may allow nonnative fish to escape through the dam, adversely affecting native fish species downstream in the Grand Canyon. In this study we characterized the seasonal distribution of nonnative fishes in the vicinity of GCD and identified environmental conditions that may …

Relationship Between The Physical Properties And Oil Binding Capacity Of Fats, Melissa Abigail Marsh

All Graduate Theses and Dissertations, Fall 2023 to Present

Fats play a significant role in shaping the characteristics of foods, influencing texture, mouthfeel, appearance, and nutritional attributes. An important property of fats is their ability to entrap liquid oil known as oil binding capacity (OBC). Poor OBC of fats frequently leads to shortened-shelf life of foods caused by quality issues due to unwanted chemical and physical changes. In natural nut butters without additives, low OBC often results in a visual oil layer forming at the surface. In filled chocolates such as truffles, pralines, and peanut butter cups this low OBC can result in unwanted textural and visual changes.

Comparative Morphology And Development Of The Trigeminally Innervated Infrared-Imaging System In Boas And Pythons, Helen Bond Plylar

All Graduate Theses and Dissertations, Fall 2023 to Present

Boas and pythons use specialized sense organs called pit organs to detect radiant heat. Pit organs in these lineages occur in paired arrays along the upper and lower jaws and are served by the trigeminal nerve (the fifth cranial nerve and one of the largest). Information from the pit organs travels via branches of the trigeminal to the brain and ultimately is processed in the optic tectum, along with information from the visual system. That means these snakes effectively “see” heat. While studies of the pitviper infrared-imaging system are numerous, very few studies of this system in pythons or boas …

A Scoping Review On The Experiences Of Queer And Trans Students In Stem, Elliot P. Tingey

All Graduate Theses and Dissertations, Fall 2023 to Present

Efforts to increase diversity in STEM (science, technology, engineering, and mathematics) are ongoing, but within these efforts queer and trans individuals are often left out. While initial data does suggest that queer and trans individuals are significantly absent from the STEM workforce, research into the causes of such underrepresentation is scattered. Given the importance of educational experiences in the pursuit of a STEM career, it is likely that these early experiences may play a role.
