Revisiting Community Water Fluoridation, Jessica Marie Seyfried

Master's Theses

There is a bourgeoning controversy unknown to many surrounding one of the CDC’s top ten public health achievements of the 20^th century. After more than 50 years of implementation, community water fluoridation may not have achieved the declines in caries rates we once thought or hoped for, especially in light of alternative approaches to preventing caries including but not limited to other sources of fluoride supplementation, changes in diet, and tooth brushing behavior.

In fact, a survey of past research highlights the fact that this policy decision may be based on out of date and/or a lack of research …

The Tunisian Revolution: Empire And The Power Of The Multitude, Caroline A. Burns

Master's Theses

The self-immolation of Mohammed Bouazizi ignited the revolution that would oust Tunisian dictator Ben Ali in 2011. The momentum of the revolution in Tunisia spread ideas, tactics, and revolutionary chants across borders to various parts of the globe. The speed and intensity of the revolution dominated the attention of the unsuspecting global community. In order to understand the conditions under which this revolution transpired, I use Michael Hardt and Antonio Negri's theory of Empire to show how the contemporary global system functions. Through the historical development of Tunisia and concurrent rise of Empire emerges "the multitude," the heterogeneous manifestation of …

Dislocation And Adjustment Of International Student-Athletes, Thiago Brito Lopes

Master's Theses

One reason that attracts international student-athletes to American universities could be the interest in earning high quality education with the possibility of playing high performance sports. However, when compared to other international students, differences are seen: Other foreign students who look for a degree in the US desire not only an international education, but also potentially staying in the country. The University of San Francisco, where a cosmopolitan city meets education, fits it best. At USF, 82 countries are represented, reaching a number of 1708 students. Approximately ¼ of the whole student population is international. The ratio with student-athletes is …

Power, Subjectivity, And Life In Spain: A Continuation Of Elite Power, Matthew Mason

Master's Theses

On December 20, Spain will hold national elections to determine the new prime minister and national and local parliaments. These elections will be another crossroads in the long history of Spain. The elections come about in a political and social atmosphere of ‘change’ and ‘regeneration,’ marked by the rise of two new political parties, Podemos and Ciudanos. These parties are the new forces in the political scene in Spain. This atmosphere of change is the result of the 2008 economic crisis. The economic crisis of 2008 was not only an economic crisis in Spain, but it provoked a political and …

The Multidimensionality Of Schoolgirl Dropouts In Rural Bangladesh, Tiffany Yancey

Master's Theses

This thesis outlines the underlying causes for girl dropouts in the secondary school system of rural Bangladesh and assesses the barriers that affect adolescent girls and their families. The complex dynamics of the historical context within the patriarchal-dominant structure of society creates a system that hinders girls’ education and forces them into marriage at an early age. Poverty and lack of parental involvement in schools, as well as societal traditions and lack of government infrastructure play an enormous role and are the main structural factors that are linked to schoolgirl dropouts in this study. This thesis also analyzes previous education …

Evolution Of A Nation After A Dictatorship: How Law, Politics And Society Of The 1973 Dictatorship In Uruguay And Of The Subsequent Return Of Democracy In 1985, Potentially Helped Evolve The Nation Of Today., Jonathan A. Fein Proaño

Master's Theses

In 1973, Uruguay’s president authored a coup d’état with the military and changed the history and fabric of Uruguay. Once democracy returned to Uruguay in 1985, it was a chance to see if an evolution of the law, politics and society would occur. This thesis aims to analyze and understand the patterns of change and de-evolution or evolution that happened during the dictatorship and then over the last 30 years. I break down the process of changes that happened legally and politically, how the dictatorship and its leaders used law to destroy rule of law, and how society changed.

The German Army At A Crossroads Of Modernization, Sarah E. Liebig

Master's Theses

This thesis examines the German civil-military relationship and the challenges the country is facing amidst modernizing reforms to the German armed forces. Over the last quarter of a century, new international security threats have manifested and continue to transform requiring Germany to adapt its military and defense policies in order to effectively protect itself and serve as a capable ally to other member states of international organizations such as NATO and the EU. The adaptations and reforms required of Germany have led to concern that the cornerstone civil-military relationship concepts are at risk. In this thesis I identify the major …

Modeling And Analysis Of A Steel Truss Railroad Bridge Traversed By Trains At Various Speeds, Surendra Baniya Mr.

Master's Theses

The dynamic analysis of a truss railroad bridge under a moving train is very complicated. The simplified model where an entire bridge is represented by a single beam of equivalent stiffness could be suitable to analyze a girder bridge, but is not adequate to analyze accurately truss bridges, which inherently consist of numerous structural components. Moreover, due to the repetitive nature of train loading on a railroad bridge, there is an excitation frequency as a function of speed associated with each moving train. If this loading (excitation) frequency coincides with the natural frequency of the bridge, the bridge response builds …

“How Do You Define Yourself?” Mobilizing Leadership In The Graduate Employee Union Movement, Kathleen Ragon

Master's Theses

Social movement scholars agree that leadership plays a crucial role in the emergence, structure, and outcomes of social movement organizations (SMOs) and is thus an indispensable area of research. The vast majority of theories of leadership to date have been developed in contexts where participants’ movement identities are relatively stable (e.g., gender, sexual, or occupational) and engagement in the site of contestation will be long-term (e.g., workplace or nation state). However, the recent proliferation of graduate student employee unions poses a challenge to this literature because graduate students’ employment is by its very nature temporary and variable; graduate assistantship appointments …

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

The Ecological Importance Of Brachiopods Versus Bivalves In The Paleozoic: Taphonomy, Biomass, And Energy Use, Shannon (Shin-Nan) Hsieh

Master's Theses

Brachiopods have commonly been considered more important than bivalves in Paleozoic ecosystems due to their greater global diversity and greater abundance in many fossil assemblages. New sampling-standardized diversity curves verify that brachiopods were more diverse than bivalves at the global level in the Paleozoic; they declined in the Permian-Triassic extinction, largely recovered, then faded away later in the Mesozoic. However, the subordinate ecological status of bivalves within local Paleozoic ecosystems has been challenged on two fronts. First, bivalve abundance may be underestimated due to preferential dissolution of aragonitic shells. Second, bivalve contribution to ecosystem function may be underestimated by abundance …

Predictors Of Improvement In Risk Reduction Skills Among Hiv Infected Drug Users, Rashmi Dahal

Master's Theses

Background and Objective: Unsafe needle use and unprotected sex are behaviors that have been associated with HIV transmission. Evidence-based behavioral intervention approaches are widely available for preventing HIV transmission, but neurocognitive impairment (NCI) may impede many intervention participants’ capacity to fully benefit from such interventions, leaving them vulnerable to HIV transmission risk. This study examines the impact of NCI on specific intervention outcomes expected to be enhanced through intervention participation.

Methods: Participants were 74 HIV+ opioid-dependent persons participating in methadone maintenance drug treatment and who reported drug- or sex- related HIV risk behavior. Using regression analyses, NCI, HIV knowledge (information), …

Adaptive Pi Control To Realize Sinusoidal Ripple Current Charging In Battery Charger Systems, Jen-Guey Chen

Master's Theses

This thesis proposes the adaptive PI gain control to regulate sinusoidal ripple current (SRC) in battery charger systems. The SRC charge method is suited for fast and efficient charging. Y.D Lee (2015) propose that SRC charge method can reduce the charging time, decrease the charging temperature and improve the charging efficiency by applying optimal frequency to charge the battery. In order to determine optimal frequency for charging, the swept frequency is required in SRC charge method. Therefore, in order to perform SRC charge approach, the battery charger systems have to be capable of handling swept frequency input and regulating high …

Europe’S Refugee Crisis: Assessing The Factors Preventing A Coordinated Eu Response, Ali Albassam

Master's Theses

In order to escape increasing political violence in the Middle East and Africa, many refugees are fleeing by sea to seek asylum in Europe. As a result, Europe has witnessed the highest influx of refugees since World War Two. European Union member states have scrambled for a solution, seemingly unable to form a collective response. The reemergence of nationalism amid the arrival of thousands of refugees not only clouds Europe’s moral compass, but also weakens the EU and its founding principles. In an effort to contribute to the protection of refugees and the EU and its values, this thesis aims …

Effect Of Electrical Stimulation On Muscle Recruitment As It Relates To Maximal Voluntary Contraction, Kelly Stratton

Master's Theses

Regeneration of complex muscle tissue, particularly at the interface between distinct tissue types such as muscle and tendon, remains an intricate and challenging issue. One approach recommended for regeneration is electrical stimulation (ES), which involves delivering an electrical pulse into the body to induce muscle contraction. Despite its well-documented effectiveness in both clinical rehabilitation and tissue engineering, little is known in terms of monitoring direct muscle response to stimulation. The recruitment mechanism for muscular contraction with stimulation is unclear, and to understand the muscle capabilities, it is necessary to filter out the electrical stimulation pulses from electromyographic (EMG) muscle activity, …

Transit Era Hartford: Using The Past To Plan The Future, Adam Polinski

Master's Theses

The past several decades have been accompanied by a growing concern regarding the viability of auto-centric planning as it relates to environmental, social, and economic sustainability. Research has shown that dense, multimodal urban development has many benefits over the sprawling land use patterns that are so common today. As there are few modern places that are free of automobile-oriented development, historic cities often act as great sources of this information. Unfortunately, it is difficult to fully explore and understand Pre-Automobile Era cities because of a lack of accessible data.

Through GIS digitization of maps of Hartford, Connecticut around 1920, it …

Density-Based Clustering Of High-Dimensional Dna Fingerprints For Library-Dependent Microbial Source Tracking, Eric Johnson

Master's Theses

As part of an ongoing multidisciplinary effort at California Polytechnic State University, biologists and computer scientists have developed a new Library-Dependent Microbial Source Tracking method for identifying the host animals causing fecal contamination in local water sources. The Cal Poly Library of Pyroprints (CPLOP) is a database which stores E. coli representations of fecal samples from known hosts acquired from a novel method developed by the biologists called Pyroprinting. The research group considers E. coli samples whose Pyroprints match above a certain threshold to be part of the same bacterial strain. If an environmental sample from an unknown host animal …

Regional Wine Reputation: How It Influences Trade And Consumer Purchasing Behavior, Joseph Bernard Ostrander

Master's Theses

ABSTRACT

Regional Wine Reputation: How It Influences Trade

and Consumer Purchasing Behavior

Joseph Bernard Ostrander

What are wine trade buyers and wine consumers willing to pay for a bottle of wine based on the reputation of the grape growing region apart from existing corporate branding reputation, variety popularity, or accolades from industry periodicals and celebrity wine critics? Results from a previous study discovered how attitudes about place-of-origin influenced consumer perceptions regarding the quality associated with the wines from that region. Related research also looked at how wine prices depended on the quality associated with a wine region’s reputation when linked …

Gender, Othering, And Loki 2015, Amanda Munson

Master's Theses

With many enigmatic characters and engaging stories, Norse literature and mythology have had a formative impact on English literature from the early Middle Ages in poetry like the Edda and many Icelandic sagas. A lot of scholarship has been done on Nordic myth and literature, including character studies on many figures, especially Odin and Thor. However, it is difficult to find studies of the figures who make up the "other" in Nordic tales, such as the trickster Loki. While Loki plays a significant role in many tales, his position as the "other" in general Norse mythology and folklore is perhaps …

Medical Image Registration Using Artificial Neural Network, Hyunjong Choi

Master's Theses

Image registration is the transformation of different sets of images into one coordinate system in order to align and overlay multiple images. Image registration is used in many fields such as medical imaging, remote sensing, and computer vision. It is very important in medical research, where multiple images are acquired from different sensors at various points in time. This allows doctors to monitor the effects of treatments on patients in a certain region of interest over time. In this thesis, artificial neural networks with curvelet keypoints are used to estimate the parameters of registration. Simulations show that the curvelet keypoints …

"Persephone's Contemporary Dilemma: Consent, Sexuality, And "Female Empowerment." [2015], Cassandra Elizabeth Cerjanic

Master's Theses

Greek mythology never strays very far from Western imagination. Though every few years literature involving the infamous Gods tapers off into the back of our collective minds, a resurgence soon follows. The late Romantic literary movement (as popularized by Lord Byron, Percy Bysshe Shelly, and John Keats) depended heavily upon Greco- Roman mythology to help illustrate characters that existed somewhere between the shadow of imagination and the truth of humanity. Perhaps in an attempt to harken back to Romanticism, contemporary poetry has once again given life to the Greek Gods. Mythological characters can be seen throughout the works of modern …

Postcolonialism And The Marshallese Diaspora: Structural Violence And Health In The Marshallese Community In Springdale, Arkansas, Alexander J. Hirata

Master's Theses

Despite moving to the United States for better healthcare, among other benefits, Marshallese Compact of Free Association (COFA) migrants residing in Springdale, Arkansas continue to face similar acute health problems as Marshallese living in the Republic of the Marshall Islands (RMI), and often without access to health services. These problems include high rates of noncommunicable diseases, such as type 2 diabetes and thyroid cancer, as well as rare conditions such as Hansen’s Disease.

To research this, I studied the limited texts surrounding the Marshallese diaspora, as well as relevant bodies of literature: postcolonialism, Pacific migration theory, and global health and …

Spatial Variability Of Soil Velocity Using Passive Surface Wave Testing, Daniel Raymond Wagstaffe

Master's Theses

Lifelines such as highways, pipelines, telecommunication lines, and powerlines provide communities with vital services, and their functionality is dependent upon the foundation soil that supports them. However, when designing the infrastructure, it can be difficult to know where to test the soil in order to give spatially representative sampling, particularly for long, lifeline structures. Finding this distance requires knowledge of the spatial correlation and/or the spatial variability of the soil parameter (stiffness, cohesion, etc.). But this correlation distance is not typically found in practice because it requires large amounts of data and the costs of retrieving that data can be …

An Evaluation Of The Disposition Of R941000, A Tetrazolone-Telmisartan Analog: A Case Study Of The Suitability Of Tetrazolone As A Carboxylic Acid Bioisostere, Ryan Brant Murray

Master's Theses

Carboxylic acids are ubiquitous in medicinal compounds, such as nonsteroidal anti-inflammatories, statins, hypertensives, and anticoagulants. Despite their prolific use, unfavorable characteristics such as metabolic instability, poor membrane permeability, and toxicity have been associated with this moiety in some instances. Bioisosteres have been employed to attenuate these issues. However, bioisostere use can alter drug potency and disposition. Recently, our company demonstrated the feasibility of the tetrazolone moiety as a carboxylic acid bioisostere for the angiotensin II antagonist telmisartan. R941000 (telmisartan-tetrazolone analog) was a potent in vitro inhibitor of angiotensin II and possessed a similar disposition to telmisartan. To the best of …

Management Strategy Evaluation For The Atlantic Surfclam, Spisula Solidissima, Using A Fisheries Economics Model, Kelsey M. Kuykendall

Master's Theses

The Atlantic surfclam, Spisula solidissima, is an economically valuable bivalve harvested along the northeastern United States. The surfclam’s range has contracted and the center of the stock’s distribution has shifted north driven by warmer bottom water temperatures. Declining landings per unit effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. The objective of this project is to perform a management strategy evaluation (MSE) for Spisula solidissima. The terminal goal is to identify a preferred management option that promotes enhanced surfclam productivity in the …

Child Routines And Self-Regulation As Mediators Of Parenting Practices And Externalizing Problems In Preschoolers, Lovina R. Bater

Master's Theses

Studies clearly indicate that parenting practices relate to child externalizing behaviors, although the mechanisms underlying this relation are less well understood. Researchers suggest that daily routines are one way through which parenting practices relate to externalizing behaviors, allowing children to regulate their thoughts, emotions, and behaviors accordingly, potentially promoting development of appropriate self-regulatory behaviors. Self-regulation is also a possible route through which child routines inversely relate to externalizing behaviors. These relationships have been tested in school-age and older children, yet self-regulatory abilities are known to develop during the preschool period. This study examined child routines and self-regulation as serial mediators …
