The Resisters: Contemporary Ethiopia Through A Feminist Lens, Eldana Mathias Temesgen

Master's Theses

Based on the recent mass protests in Ethiopia, there is a strong indication that the Oromo people of Ethiopia, who are at the forefront of these protests, have been placed in a position of marginal importance, influence and power in their society. Due to the power and agency wielded by the government, some ethnic groups in Ethiopia, including the Oromo ethnic group, claim to be underrepresented on a political, economic, and social scale, which has led to conflict.

The nuances of ethnic based conflict, such as the situation in Ethiopia, have been tackled through several disciplines and examined through different …

Three Essays On Tax Abuse And The Fulfillment Of Economic And Social Rights, Ute Reisinger

Master's Theses

Global tax abuse is one of the key obstacles to sustainable development. Each year more than USD one trillion are lost to cross border tax abuse and stored away in tax havens. We establish that tax abuse accumulates capital, makes tax systems more regressive and diminishes government revenues. Tax abuse consequently indirectly increases economic inequality and relative poverty and reduces social expenditure affecting both dimensions of economic and social rights fulfillment: the ability of people to claim their rights in the market place or through the provision of entitlements. We test our theory in a cross-sectional study and find empirical …

The Role Of Orphan Nuclear Receptor Dax-1 (Nr0b1) In Human Breast Cancer Cells: Expression, Proliferation And Metastasis, Erin Dishington

Master's Theses

The orphan nuclear hormone receptor DAX-1 (Dosage Sensitive Sex Reversal, Adrenal Hypoplasia Congenita on the X Chromosome, gene 1) plays an important role in the development of adrenal and gonadal tissues and functions as a global negative-regulator of steroidogenesis. In addition, it is known to be involved in several diseases including some cancers. Herein, we describe our examination of the role of DAX-1 in breast cancer, specifically its influence on proliferation and metastasis and its expression during progressive stages of disease. In an effort to understand how DAX-1 influences breast cancer cell proliferation and metastasis, we used MCF7 breast cancer …

Oxygen Isotopic Composition Of Nitrate Produced By Freshwater Nitrification, Danielle Boshers

Master's Theses

Identifying sources of nitrate (NO₃^-) in the environment is important to elucidate causes of water quality impairment and eutrophication. Measurements of naturally occurring stable isotope ratios of nitrogen (¹⁵N/¹⁴N) and oxygen (¹⁸O/¹⁶O) in NO₃^-, can be used to determine the sources, dispersal, and fate of natural and contaminant NO₃^- in aquatic environments. To this end, it is necessary to know how NO₃^- isotopologues are modified by biological reactions, as heavy and light isotopes have different reaction rates. One important microbial reaction that …

Il-17a And The Receptor Are Regulated By Runx3 During Fracture Healing, Satoko Matsumura

Master's Theses

Enhancing bone repair is the key process which facilitates the improvement of fracture healing outcomes. Despite of many studies regarding osteogenesis induction, Bone morphogenetic proteins-2 (BMP-2) and Platelet-derived growth factor-BB (PDGF-BB) are still the only two the Food and Drug Administration (FDA)-approved treatment^{1, 2}. To develop potential treatment modalities, it is essential to understand the role of transcription factors in fracture healing and how they may be specifically targeted in preclinical models to enhance bone regeneration. While the Runt-related transcription factor 2 (Runx2) is known to play a crucial role in osteoblastogenesis, the role of Runx3, a homologue …

Eeg Characterization During Motor Tasks That Are Difficult For Movement Disorder Patients, Adam Joshua Aslam

Master's Theses

Movement disorders are a group of syndromes that often arise due to neurological abnormalities. Approximately 40 million Americans are affected by some form of movement disorder, significantly impacting patients’ quality of life and their ability to live independently. Deep brain stimulation (DBS) is one treatment that has shown promising results in the past couple decades, however, the currently used open-loop system has several drawbacks. By implementing a closed-loop or adaptive DBS (aDBS) system, the need for expensive parameter reprogramming sessions would be reduced, side-effects may be relieved, and habituation could be avoided. Several biomarkers, for example signals or activity derived …

The analysis of Lenski’s works was contextualized using literature focusing on the concepts of character representation, authority, …

The Legacy Of British Rule On Lgbt Rights In Jamaica And The Cayman Islands, Zachary Stewart

Master's Theses

This thesis explores the relationship between British colonial influence and Lesbian, Gay, Bisexual, and Transgender (LGBT) rights in the Caribbean. Comparing the Cayman Islands, a British Overseas Territory, and Jamaica, an independent former colony of the United Kingdom, the situation for LGBT people is evaluated. While Jamaica has serious abuses and a concerning situation for the human rights of LGBT people, the Cayman Islands’ LGBT community’s position is far less concerning. Owing to its continued connection to the United Kingdom of Great Britain and Northern Ireland, the Cayman Islands’ LGBT rights situation is much less dire. Through British influence via …

Let's Talk Story: Waikiki And Its Social Displacements In Oral Histories And Print, 1901–1935, Alika Bourgette

Master's Theses

The everyday experiences of Waikiki’s residents of color often escaped official and semi-official records of historical events. When concerning Native Hawaiians and other nonwhite peoples, haole elite journalists and policymakers viewed their land, possessions, and bodies as opportunities for the cultural commodification, sexualization, and reimagination. As part of the redevelopment efforts of the Waikiki shoreline in the early twentieth century, state and commercial actors worked to affect the systematic erasure of Native Hawaiian and resident Asian spaces. This study utilizes extensive collections of oral histories from marginalized Waikiki residents of color to provide counterpoint to notions of indigenous passivity and …

A Comparison Study Of Composite Laminated Plates With Holes Under Tension, Joun S. Kim

Master's Theses

A Comparison Study of Composite Laminated Plates with Holes under Tension

A study was conducted to quantify the accuracy of numerical approximations to deem sufficiency in validating structural composite design, thus minimizing, or even eliminating the need for experimental test. Error values for stress and strain were compared between Finite Element Analysis (FEA) and analytical (Classical Laminated Plate Theory), and FEA and experimental tensile test for two composite plate designs under tension: a cross-ply composite plate design of [(0/90)4]s, and a quasi-isotropic layup design of [02/+45/-45/902]s, each with a single, centered hole of 1/8” diameter, and 1/4" diameter (four sets …

This research highlights the multiple roles that women successfully executed as they cared for …

#Sayhername: Negotiating Issues Of Victimhood, Violence, And Visibility, Carol Ann Jackson

Master's Theses

This thesis analyses both news articles and tweets discussing #SayHerName and both implicit and explicit discussions of race, gender, and sexuality. Prior research on media representations of race, gender and violence has found that black women have been denied visibility as victims in unilateral media portrayals of gendered violence, which has contributed to the social problem of black women’s marginalization as their experiences of injustice become invalidated. This denial is not directly stated, rather it functions through a use of controlling images which reproduce racist, sexist, and heteronormative media messages by naturalizing black women as devious, promiscuous, and aggressive. This …

Identifying And Reducing Variability, Improving Scaffold Morphology, And Investigating Alternative Materials For The Blood Vessel Mimic Lab Electrospinning Process, Evan M. Dowey

Master's Theses

The work of the Cal Poly Tissue Engineering Lab is primarily focused on the fabrication, characterization, and improvement of “Blood Vessel Mimics” (BVMs), tissue engineered constructs used to evaluate cellular response to vascular medical devices. Currently, cells are grown onto fibrous, porous tubes made using an in-house electrospinning process from PLGA, a biocompatible co-polymer. The adhesion and proliferation of cells in a BVM is reliant on the micro-scale structure of the PLGA scaffold, and as such it is of great importance for the electrospinning process to consistently produce scaffolds of similar morphologies. Additionally, it has been shown that cell proliferation …

Key Differences Between Hepatic And Intestinal Apoc3 Regulation And Expression, And Implications For Cardiovascular Disease Risk, Gabrielle West

Master's Theses

In the intestine, apoC-III delays chylomicron secretion, and causes a decrease in chylomicron size. Once apoC-III is in circulation, apoC-III delays triglyceride-rich remnants clearance by inhibiting lipoprotein lipase and liver low-density lipoprotein receptor. In humans, high levels of plasma apoC-III directly result in hypertriglyceridemia. ApoC-III is a critical cardiovascular risk factor, and humans expressing null mutations in apoC-III are robustly protected from cardiovascular disease. Because of its critical role in elevating plasma lipids and CVD risk, the factors that regulate apoC-III expression in the liver have been determined, and include glucose, insulin (through FoxO1), and dietary fat. Considerably less is …

Development Of An In-Situ Passive Sampling Device For Munitions Compounds And Sulfate, Joseph K Warren

Master's Theses

Passive sampling is a novel method of analyte concentration from the environment that strives to bring greater ease to field sampling regimes than traditional liquid-solid phase extractions (SPE). It is easier to deploy than a Niskin bottle or CTD rosette, and easier to recover than hoisting up dozens of liters of water. Passive sampling also offers the opportunity for wider exploratory studies, as compounds can be selectively extracted back in lab, rather than having to select a particular phase SPE and follow phase-specific elution methods. In this study, Ethylene Vinyl Acetate copolymer (EVA) was used as a marine sorption and …

Investigating Program Evaluation Implemented By Rural Education Systems To Determine The Efficacy Of Speech-Language Telepractice Services, Allyson Doreen Montgomery

Master's Theses

Given the importance of providing speech-language services to students in rural areas, school districts have begun adopting telepractice as a primary service delivery model (American Speech-Language and Hearing Association [ASHA], n.d.b; Forducey, 2006; & Polovoy, 2008). However, as the demand for telepractice grows, so does the need for a strong method of program evaluation (ASHA, 2005a). The purpose of this study was to investigate the methodologies district level administrators use to evaluate effectiveness and ensure the validity of telepractice services. Two district level administrators from distinct rural educational cooperatives participated in this study. Both were from two distinctive Midwestern states …

Born To Run: A Grounded Theory Study Of Cheating In The Online Speedrunning Community, Christopher G. Brewer

Master's Theses

Video games represent a growing genre of media quickly becoming one of the leading forms of entertainment (Jordan, 2014). This popularity has allowed new playstyles to emerge across the video game genre, such as e-Sports and speedrunning. In particular, the speedrunning community has somewhat redefined what it means to “cheat” in a video game by accepting the use certain software and hardware violations that could be seen as “cheating” to the general gaming community. This paper examined the social construction of cheating in this digital community through the use of grounded theory methods.

The Influence Of Perceived Job Flexibility And Spousal Support On The Marital Satisfaction Of Parents Of Children With Special Needs, Katie M. Perlowski

Master's Theses

Parents of children with special needs can experience more stress in their marriage than parents of children without special needs. Previous work has focused on the child as a major influence for the marital relationship, however this research sought to examine less commonly discussed factors that influence marital satisfaction for these parents. Perceived job flexibility and perceived spousal support in parenting were targeted as potential influencers. A mediation model was attempted to explain the mediating role of perceived spousal support in parenting in the relationship between perceived job flexibility and marital satisfaction. Results showed no correlation between perceived job flexibility …

Potential Of Ozone And Hydroxyl Radicals To Degrade Emerging Organic Contaminants, Lisa Elaine Vance

Master's Theses

Advanced water treatment processes are necessary for the treatment of emerging organic contaminants. Traditional treatment processes do not filter or treat these contaminants causing humans and animals to come into contact and ingest them, both causing illness. Advanced oxidation processes are a good alternative method, but are cost and time intensive.

Previous research on ozone and hydroxyl radicals leads to the conclusion that they might be a vial option for advanced water treatment processes. To test the effects of ozone and hydroxyl radicals on the destruction of algae, ozonated phosphate buffer was mixed with Anabaena and modified BG11 culture media …

Investigation Of Ammonia And Nitrate Removal From Municipal Wastewater Using Biowish, Emily Holland

Master's Theses

This research entails investigation of ammonia, nitrate, and nitrite removal from wastewater using a proprietary blend of bacteria known as BiOWiSH^TM. The degradation rates of ammonia, nitrate, and nitrite for Aqua were determined using wastewater at the San Luis Obispo Water Resource Recovery Facility (SLO WRRF). Laboratory and field experiments were conducted to test how Aqua compared with natural bacteria for removal of nitrogen compounds. Preliminary data suggested that Aqua performed nitrate removal best in SLO WRRF wastewater at the secondary clarifier. Aqua could perform anoxic and aerobic denitrification in secondary clarifier wastewater. In mineral media, Aqua removed …

As such, the processing conditions of these systems are important to the construction of high- performance optoelectronics. Polythiophenes are model conjugated polymers that have been studied extensively in halogenated organic …

Removal Of Nitrates From Stormwater Using Nanoclays, Rubia Siddiqi

Master's Theses

Creeks and rivers are often polluted as a result of stormwater runoff that carries various contaminants in to open water bodies, causing adverse environmental and health effects. Low impact development (LID) techniques are currently employed to treat this runoff prior to discharge. Nitrate, however, is not consistently removed by these LID techniques. This study analyzed the ability of several nanoclays to remove nitrate in runoff and determined the feasibility of using them as a soil supplement for LID implementation. Six different nanoclays and HCl-treated clays were compared (pre-modified trimethyl stearyl ammonium nanoclay, pre-modified dimethyl dialkyl amine nanoclay, unmodified hydrophilic bentonite, …

The current study aims to examine the influence of parent-child sexual communication on adult sexual communication when those children reach adulthood and engage in romantic relationships. Parent-child sexual communication, attachment styles, sexual attitudes, and partner sexual communication were examined for influence on the physical and emotional relationship satisfaction of emerging adults. Study 1 included a quantitative analysis with 553 emerging adults participating in an online survey, and study 2 incorporated a qualitative analysis with an additional 7 emerging adults participating in online …

Black And Blue: Competing Social Constructions Of Police On Instagram And Twitter, Mary Frances Thornhill

Master's Theses

Mass media outlets newspapers and television were traditionally where individuals gathered their news information; however, with the growth of new media platforms like Twitter, Facebook, and Instagram, individuals are now co-producers of the content that is seen by the public. Previous research indicated that media-generated images of the police influence public perception and that new media outlets are becoming increasingly influential, particularly in regards to social and political conflicts. This means that research on the role of new media outlets in socially constructing reality is essential, though not much of this research has yet been completed. This current analysis fills …
