The Impact Of Upland Development And Marsh Width On Groundwater Composition In Estuarine Tidal Creeks In The Southeastern Coastal United States, Meghan Shanahan

Theses and Dissertations

Coastal upland development has been shown to negatively impact surface water quality in tidal creeks along the southeastern coastal United States, but the impact of development on groundwater quality is not well understood. Increases in impervious cover associated with development has the potential to increase groundwater contamination as well as reduce fresh rainwater infiltration into the subsurface, which may decrease discharge of fresh groundwater to the estuary. We hypothesized that groundwater nutrient concentrations and salinity ranges would be higher in developed watersheds than in undeveloped watersheds.

Groundwater discharging from coastal uplands often travels through salt marshes before discharging to tidal …

Black Power And Neighborhood Organizing In Minneapolis, Minnesota: The Way Community Center, 1966-1971, Sarah Jayne Paulsen

Theses and Dissertations

The Way Opportunities Unlimited, Inc. was a non-­‐profit community center that operated from 1966—1984 in Minneapolis, Minnesota. Inspired by the national black power movement that arose in the 1960s, this community center led a local movement for African American equality. This thesis investigates The Way as a unique example of how black power ideology was implemented at the local level, in a city with a statistically small black population, presenting a northern urban context often overlooked by historians. The Way offered a space where aspiring young black musicians could perform, including Prince.

Understanding The Impact Of Land Use On Microbial Water Quality To Support Decisions For A Future Land Use Plan, Mohammed Tawfiq Aljassim

Theses and Dissertations

May River meandering through the Town of Bluffton, South Carolina has been known for its high level of water quality. The May River is one of the major sources of shellfish harvesting in South Carolina. Due to the non-point source pollution of fecal coliform, the water quality of the May River became degraded. As a result, shellfish harvesting classification in the May River was downgraded for the first time in its history. The rapid growth of the Town has led to a change in land use, which might be related to the increased levels of fecal coliform in the stream …

Residential Mobility And Enrollment Churn In A Medicaid Population, John E. Stewart

Theses and Dissertations

Previous investigations show high rates of enrollment discontinuity, or churn, among Medicaid participants. Discontinuity of coverage can limit appropriate use of health care, increase emergency department utilization and in-patient hospitalization, negatively affect self-reported health, increase health care spending, and compound Medicaid administrative costs. Efforts to more fully understand and ultimately reduce enrollment churn thus are vital to Medicaid agencies and beneficiaries. Residential moves are life transitions, often marking other significant life events (e.g., changes in employment or family structure) that can alter eligibility for Medicaid benefits. Few studies have examined residential moves among Medicaid members, or considered residential mobility as …

Turán Problems And Spectral Theory On Hypergraphs And Tensors, Shuliang Bai

Theses and Dissertations

Turán problems on uniform hypergraphs have been actively studied for many decades. However, on non-uniform hypergraphs, these problems are rarely considered. We refer a non-uniform hypergraph as an R-hypergraph where R is the set of cardinalities of all edges. An R-graph H is called degenerate if it has the smallest Turán density |R(H)|−1. What do the degenerate R-graphs look like? For the special case R = {r}, the answer to this question is simple: they are r-partite r-uniform hypergraphs. However, it is more intrigue for the other cases. A degenerate hypergraph is called trivial if it is contained in the …

Comparative Effectiveness Of Conventional And Novel Sampling Methods For The Recruitment Of Sexual Minority Identified Women, Sarah M. Piperato

Theses and Dissertations

Sexual minority identified (SMI) women have an amplified risk for risky health behaviors and chronic health conditions. Current research on mechanisms related to health disparities in SMI women is limited. Research targeting SMI women has relied on small, convenience samples to address health disparities. Due to the nature of this population, probability sampling methods are ineffective and inefficient and cost prohibitive. The purpose of this dissertation was threefold. First, we examined the current state of literature to gain insight on prevalent sampling strategies used to access SMI women for health-related research. Second, we compared the efficacy of two sampling strategies, …

Development Of A Supplier’S Delivery Time And Delivered Quality Performance Index And Assessment Of Alternative Decisions Regarding Underperforming Suppliers For The Aerospace Industry, Clint Saidy

Theses and Dissertations

This study investigates current practices of supplier’s delivery assessment so that a comprehensive index and a cost function model could be properly developed. Following a thorough literature review, a framework was created based on a penalty cost function that integrates both suppliers’ ability to deliver on time, as well as suppliers’ capability to deliver good quality. Afterward, suppliers could then be ranked and placed either in good standing, or transversely on probation. Underperforming suppliers face three potential outcomes based on current literature: (1) switching supplier, (2) increase collaboration, (3) maintaining the status quo. The decision vis-à-vis failing suppliers is based …

In Chapter 1, the overall background …

Diction For Mandarin/Chinese Singers: A Methodology To Achieve Resonant Tone And Vowel Unification In Western Choral Music, Chien-Yi Li

Theses and Dissertations

Understanding vowel production is vital in order to develop a rich choral tone based on unified vowels, appropriate resonance, and freely produced singing. Likewise, correct articulation of consonants produces understandable text. Enunciating the texts of Western choral repertoire is often challenging for Mandarin singers, and learning English pronunciation requires a significant amount of rehearsal time. Further, amateur and developing singers in Mandarin-speaking countries often employ a bright sound and lowered soft palate when singing, in common with their native speaking position. Therefore, voice placement, resonance, and vowel modification must be carefully addressed and improved upon when they are singing Western …

Male Gender Equality Ideology, Empathy, And Prosocial Bystanding Behaviors And Intentions: A Path To Intimate Partner Violence Prevention On College Campuses, Virginia Diane Woodbrown

Theses and Dissertations

Objective: The importance of involving young college males as prosocial bystanders who will step in to stop sexual violence on college campuses is acknowledged as an important next step in reducing violence against women. However, research revealing which factors influence males to become engaged in this way is nascent. Prior research designed to uncover which factors lead people to step in as prosocial bystanders has primarily focused on situational factors rather than personal characteristics, and has not explored males in the context of intimate partner violence (IPV) more specifically. Method: Survey data from 1,455 male participants, ages 18 through 25, …

A Divisive Community: Race, Nation, And Loyalty In Santo Domingo, 1822 – 1844, Antony Wayne Keane-Dawes

Theses and Dissertations

On 8 February 1822, Haitian President Jean-Pierre Boyer entered Santo Domingo and ended the short-lived experiment of a moderate republic and the triumph of a popular and radical vision of nationhood. For the next two decades, this unified Haitian Republic faced the scrutiny of Spanish, French, and British slave empires, fueled by the accounts and reports of those Dominicans who rejected this change in events. Using government correspondences, reports, pamphlets, and proclamations, this study argues that the Haitian Unification affected Dominican political allegiances and drove white elites to support Spanish monarchy in contrast to those in Santo Domingo who supported …

Association Between Perception Of Police Prejudice Against Minorities And Juvenile Delinquency, Kwang Hyun Ra

Theses and Dissertations

Criminologists have long studied police prejudice with the assumption that it is a fundamental problem resulting in discrimination against certain racial and ethnic groups. However, little research has examined how individuals’ perceptions of police prejudice (PPP) influences compliance or delinquency behavior among the public. To fill this gap, in this paper, I reviewed relations between police and racial/ethnic groups, theorized an association between PPP and juvenile delinquency, and empirically examined the association.

The long history of racial/ethnic prejudice and discrimination predisposes racial/ethnic minorities to consider themselves targets of discrimination and to feel powerless. Moreover, some minorities justify the current system …

Computations Of The Dynamic Fracture Of Plane Structures By The Extended Finite Element Method, Iman Asareh

Theses and Dissertations

Finite element methods for the simulation of dynamic fracture in plane structures are presented. The method is a modified extended finite element method (XFEM) for dynamic fracture simulations with a new methodology to construct the XFEM basis functions for discontinuities. In contrast to conventional XFEM in which the extended interpolation is defined to only capture the discontinuities, the proposed method describes the enrichment functions so that they reproduce both the discontinuities and the polynomial bases of sufficiently high order which are critical for finite element convergence. Such enrichment functions, by adopting the Duffy’s transformation, can be simply defined in terms …

Dynamic Simulation Of A Solar Powered Hybrid Sulfur Process For Hydrogen Production, Satwick Boddu

Theses and Dissertations

The Hybrid Sulfur process is a thermo-electrochemical cycle used to produce hydrogen from water. The process requires a high temperature energy source for H2SO4 decomposition with temperature reaching 800°C. This step is followed by SO2 - depolarized water electrolysis. Using solar energy as the high temperature energy source allows for efficient environmentally friendly production of hydrogen. This method is an alternative to traditional photovoltaic electrolysis for hydrogen production. Making the process economically competitive is a major challenge. Operating the process with changes in the availability of solar energy also increases process complexity. The dependence of the process on solar energy …

“Catering To The Local Trade”: Jewish-Owned Grocery Stores In Columbia, South Carolina, Olivia Brown

Theses and Dissertations

In the late-nineteenth and early-twentieth centuries, Jewish immigrants from eastern Europe fled persecution, anti-Semitism, and violence in search of the “American dream.” Both the Rivkin family and the Kligman/Baker family found their way to Columbia, South Carolina, rather than staying in urban centers like New York and Philadelphia. While both families eventually operated grocery stores in Columbia, their respective roles within their communities were very different.

Jacob Rivkin, and later his son Caba, originally ran a grocery in the heart of the Jewish community that sold kosher products unavailable elsewhere in the city. The popularity of Rivkin’s Grocery led to …

The Impact Of A Media Literacy Curriculum On Middle School Students’ Ability To Recognize Racial Bias In Mass Media, Amy Savage

Theses and Dissertations

This paper outlines an action research study focused on the possible effects of a media literacy curriculum on middle school students’ ability to recognize racial bias in mass media. The research study also evaluated the possible differences in sensitivity to mass media messages based on gender and race.

The effects of polymer chain length and graft density on the mechanical properties were investigated using films made solely from the grafted NPs. The ultimate tensile stress and elastic modulus increased with the increase of PS …

A Mixed Method Feasibility Assessment Of A Youth Participatory Action Research Program To Promote Physical Activity: Evaluating Implementation Within Two Pre-Existing Aftercare Programs Serving Middle School Youth, Michelle Abraczinskas

Theses and Dissertations

Obesity interventions to date have had small effects, which may be due to youth disengagement. In youth participatory action research (YPAR), youth become involved in research to make changes that impact their lives. Thus, integrating YPAR into a physical activity intervention, like we do in the current study, is a novel strategy to engage youth and increase empowerment for health behavior change. YPAR is typically implemented with high school youth, standalone, and within elective classrooms or focused after school programs; yet, YPAR can benefit all youth, so we expanded its reach into pre-existing aftercare programs. Participating youth were predominantly minority, …

Adhd Symptoms And Adult Romantic Relationships: The Role Of Partner Attachment Style, Emotion Recognition, And Personality, Katherine Knies

Theses and Dissertations

The purpose of this project was to examine the impact of ADHD within the context of adult romantic relationships more thoroughly than has previously been examined. Whereas symptoms of ADHD do seem to contribute to the quality of a relationship (Canu, 2014; Orlov, 2010; Pera, 2008), no prior research has examined the interaction between individual characteristics and partner ADHD symptoms in predicting relationship quality. The present study addressed this gap in the literature by examining the characteristics of both partners, specifically, how certain characteristics of one partner interact with the other partner’s ADHD symptoms in predicting relationship quality. Participants were …

Students today are in more culturally and socially diverse classrooms; their curriculum needs to reflect these social changes. A review of the problem of practice led to the research question: Does implementing literature circles with social justice texts in a secondary classroom foster engagement in reading and classroom discussions for students? The primary purpose of this proposed action research study was to examine if implementing literature circles with social justice texts leads to increased conversations and engagement in the classroom. …

Effectiveness Of “Good” Governance Policies Across Contexts: A Test Of The Universal Vs. Embedded View, Sabrina Ferdous Saleh

Theses and Dissertations

This dissertation aims to examine the effectiveness of “good” governance principles that are commonly benchmarked in shaping the Corporate Governance (CG) policies. Specifically, I examine the firm level internal mechanisms of Monitoring CG and Incentive CG and the country level external mechanisms of legal rules and disclosure provisions. The origin of these CG policies is rooted in the Anglo-Saxon countries, where stand-alone firms are mostly owned by the dispersed shareholders, and Type I agency problem is common between company owners and top managers. For precisely examining the generalizability of “good” CG principles, I have conducted my investigation in an empirical …
