A Flexible Service-Oriented Approach To Address Hydroinformatic Challenges In Large-Scale Hydrologic Predictions, Michael Antonio Souffront Alcantara

Theses and Dissertations

Water security is defined as a combination of water for achieving our goals as a society, and an acceptable level of water-related risks. Hydrologic modeling can be used to predict streamflow and aid in the decision-making process with the goal of attaining water security. Developed countries usually have their own hydrologic models; however, developing countries often lack hydrologic models due to factors such as the maintenance, computational costs, and technical capacity needed to run models. A global streamflow prediction system (GSPS) would help decrease vulnerabilities in developing countries and fill gaps in areas where no local models exist by providing …

The Pregnancy Penalty, Jennifer Bennett Shinall

Vanderbilt Law School Faculty Publications

Despite the renaissance of pregnancy-related scholarship over the past decade, 322 very little has been documented empirically regarding the status of pregnant women in the labor market. As such, scholars and advocates have been constrained in their ability to assess both the adequacy of current legislation and the relative urgency for new legislation. Furthermore, in the absence of labor market data, they have been limited in their ability to propose reform measures that can target the pregnant women most in need of assistance. This Article has taken an initial step towards filling these critical gaps in the literature, utilizing a …

Decision Irrationalities Involving Deadly Risks, W. Kip Viscusi, Scott Deangelis

Vanderbilt Law School Faculty Publications

This article provides an experimental analysis of two-armed bandit problems that have a different structure in which the first unsuccessful outcome leads to termination of the game. It differs from a conventional two-armed bandit problem in that there is no opportunity to alter behavior after an unsuccessful outcome. Introducing the risk of death into a sequential decision problem alters the structure of the problem. Even though play ends after an unsuccessful outcome, Bayesian learning after successful outcomes has a potential function in this class of two-armed bandit problems. Increasing uncertainty boosts the chance of long-term survival since ambiguous probabilities of …

“I’Ve Always Identified With The Women:” How Appalachian Women Ballad Singers’ Repertoire Choices Reflect Their Gendered Concerns, Sara Lynch-Thomason

Electronic Theses and Dissertations

This thesis explores how contemporary Appalachian women’s gendered experiences influence their choices of ballad repertoire. This inquiry is pursued through a feminist analysis of interviews with six women ballad singers from Madison County, North Carolina. In evaluating the women’s choices of ballads and their commentary on the songs, this thesis draws upon narratological theories as well as concepts from Appalachian traditional music studies.

This study finds that women’s repertoire preferences reveal contemporary female concerns for physical safety and political agency. The singers also extract hidden transcripts from ballad texts and use ballads to educate audiences about women’s historic oppression. However, …

Political Competition And Predictors Of Hate Crime: A County-Level Analysis, Eaven Holder

Electronic Theses and Dissertations

Research on hate crime has tended to utilize sociological frameworks to best explain the incidence of such offending, but little research has been conducted to determine whether political factors may play a role. Although Olzak (1990) touched upon the relationship between racial violence and third-party politics during the American Progressive era (1882-1914), the research did not fully articulate how political competition may influence the commission of hate crime. The current study seeks to fill this gap, while also extending concepts associated with social disorganization theory and the defended communities perspective. It does so by utilizing a longitudinal research design to …

Gaming Behaviors In Day-To-Day Life: Exploring A Problematic Gaming Behavior Scale, Christin Collie

Electronic Theses and Dissertations

Growing concern for the problematic use of video games has prompted new research in a now growing field of literature. Internet Gaming Disorder (IGD) is a proposed behavioral addiction in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). To examine the proposed criteria for IGD, a self-report problematic gaming behavior scale (PGBS) was developed for adults residing in the United States. One hundred eighty-nine participants completed an online questionnaire comprised of demographic items, general gaming information, the PGBS, and the Internet Gaming Disorder-20 Test (IGD-20 Test). Statistical analyses conducted at the conclusion of the study were consistent …

Worry In The Pews: Exploring Levels And Causes Of Worry Among Church-Goers, Jennifer Lee

Electronic Theses and Dissertations

A large body of research indicates that worry, anxiety, and depression are present in the modern American psyche at increasingly high levels. Everyday worry can lead to further mental health issues, interpersonal problems, and reduced physical wellbeing and should be reduced when possible. Previous research has examined the benefits of church attendance with varied results; however, understanding the relationship between church attendance and everyday worry could be useful in reducing the effects of worry on this population.

The purpose of this quantitative study was to measure self-reported levels and causes of everyday worry among church-goers from three congregations and to …

The Effects Of Using An Information Literacy Model On The Information Seeking Behavior Of Sixth-Grade Students, Jessica L. Kohout-Tailor

All Dissertations

This action research study describes how teaching an information literacy model affects the information behavior of sixth-grade students. The theoretical framework that supported this study was Carol Kuhlthau’s Information Search Process or ISP (1989). This study used a sequential mixed-methods design to examine the following questions: “How will teaching the Simple Four information literacy model (Alewine, 2006) to sixth-grade students affect their information seeking behavior?” The study also explored the effects the model had on students’ affective behavior through the second research question: “How will teaching the Simple Four information literacy model (Alewine, 2006) to sixth-grade students affect their confidence …

Interfacing The Liquid Sampling- Atmospheric Pressure Glow Discharge Ion Source With Orbitrap Mass Spectrometers For High Accuracy High Precision Isotope Ratio Measurements Of Uranium, Edward Dexter Hoegg

All Dissertations

The integration of the liquid sampling – atmospheric pressure glow discharge (LS-APGD) with Orbitrap mass spectrometers has led to a potential paradigm shift in the field of high certainty isotope ratio measurements. Since the dawn of the atomic age, mass spectrometry has played a critical role in performing isotope ratio measurements of uranium (U), plutonium (Pu) and other radionuclides. Traditionally, these measurements have been made using thermal ionization mass spectrometry (TIMS) instruments and, more recently, inductively coupled plasma mass spectrometry (ICP-MS) instruments. While the ability of these instruments to perform isotope ratio measurements with a high degree of certainty has …

The Effects Of Various Retort Motions On The Rate Of Heat Penetration Of A Food Simulant In Pouches, Mollye Macnaughton

All Dissertations

Processing foods in a retort is a reliable and established method of creating sterile and shelf stable products. The formula of the product and the package size dictates the processing time. Rotary retorts were invented to agitate cans to reduce the processing times and create uniform heating within the can. Recently, horizontal reciprocating agitation has become a feature of retorts referred to as Gentle Motion® and Shaka®. Oscillating agitation is an even newer possible retort motion. This research experiment was designed to (1) determine the effects of oscillating continuously and oscillating-dwell time on the rate of heat penetration in a …

Subventricular Zone Neural Stem Cells Release Extracellular Vesicles During Early Postnatal Neurogenesis, Mary C. Morton

All Dissertations

Extracellular vesicles (EVs) are nanometer sized particles released from all cells. EVs are found in all biological fluids, including cerebrospinal fluid (CSF) and blood. EVs modulate intercellular communication through the transfer of nucleic acids and proteins from donor to recipient cells. During early postnatal neurogenesis, subventricular zone (SVZ) neural stem cells (NSCs) asymmetrically divide to give rise to neuroblasts that migrate along the rostral migratory stream (RMS) and populate the olfactory bulb (OB). Other, non-neuronal cells populate the SVZ, such as microglia and endothelial cells. Microglia have been shown to regulate SVZ NSCs, but it remains unclear if this communication …

Development Of A Biomimetic, Collagen-Based Scaffold For The Repair And Regeneration Of The Annulus Fibrosus, Ryan Borem

All Dissertations

Annually, over 5.7 million Americans are diagnosed with two IVD-associated pathologies: IVD herniation (IVDH- a mechanical disruption of the concentric fibrous layers of the annulus fibrosus (AF)) and/or degeneration (IVDD- a multifactorial process which initiates within the inner gelatinous core (NP), and results in a biochemical degradation of NP tissue), with over 2.7 million requiring surgical interventions. Although both underlying pathologies are different, quite often they both lead to a decrease in IVD height, impaired mechanical function, and increased pain and disability. These pain symptoms affect approximately 80% of the adult population during their lifetime with estimated expenditures exceeding $85.9 …

Systems To Attract And Feed Pollinators In Warm-Season Lawns, Michelle Wisdom

Graduate Theses and Dissertations

Pollinating insects are responsible for the production of many agricultural crops and they require floral resources to fulfill their life-cycle. Ideally, pollinating insects will encounter a diversity of floral resources across their entire season of activity, and those floral resources can include both herbaceous and woody plant species. Managed turfgrass areas have been identified as potential locations for creating pollinator-friendly habitats. In the transition zone, where both warm- and cool-season turfgrass species are present, the persistence of herbaceous plants in warm-season turfgrasses such as bermudagrass (Cynodon spp.) and buffalograss (Buchloe dactyloides), may be affected not only by the competitive nature …

The Flexible University: Neoliberal Education And The Global Production Of Migrant Labor, Yasmin Y. Ortiga

Research Collection School of Social Sciences

This article demonstrates how neoliberal higher education has come to play a distinct role in the global market for migrant labor, where a growing number of developing nations educate its citizens for overseas work in order to maximize future monetary remittances. Located in the Philippines, this study shows how local colleges and universities attempt to impose an ideal notion of flexibility, quickly shifting academic manpower and resources to programs that would produce the ‘right’ types of workers to address foreign labor demands. Based on qualitative interviews with Filipino college educators and students, the article then discusses how such ‘flexible’ strategies …

Do Male And Female Soccer Players Differ In Helping? A Study On Prosocial Behavior Among Young Players, Paul A. M. Van Lange, Zoi Manesi, R. W. J. Meershoek, Minglian Yuan, Mengchen Dong, N. J. Van Doesum

Research Collection School of Social Sciences

Acting prosocially can be quite challenging in one of the most salient intergroup contexts in contemporary society: Soccer. When winning is the ultimate goal, balancing self-interest with helping a fellow player in distress can be a tough decision; yet it happens. To date, we know little about what motivates soccer players to offer such help in the heat of the game. We propose that sex and what is at stake will matter in such prosocial dilemma situations. A pilot study (N = 107) indicated that female players may be more likely to help than male players, but this difference was …

Karaoke Car Talk With Mark Pettit, Frances H. Miller

Faculty Scholarship

Mark Pettit and I played our own version of Carpool Karaoke long before it became a media favorite. Mark was the quiet one, a prisoner in my car for more than forty years of driving back and forth to the Law School on the Mass Pike. We were cooped up alone together for an hour and a half almost every day, sometimes under trying circumstances, including monumental traffic jams and weather horrendiomas. Some days we had more direct conversation with one another than either one of us had with our own spouses. So I thought I’d give you a little …

The Ecology Of Fecal Indicators, Dennis A. Gilfillan

Electronic Theses and Dissertations

Animal and human wastes introduce pathogens into rivers and streams, creating human health and economic burdens. While direct monitoring for pathogens is possible, it is impractical due to the sporadic distribution of pathogens, cost to identify, and health risks to laboratory workers. To overcome these issues, fecal indicator organisms are used to estimate the presence of pathogens. Although fecal indicators generally protect public health, they fall short in their utility because of difficulties in public health risk characterization, inconsistent correlations with pathogens, weak source identification, and their potential to persist in environments with no point sources of fecal pollution. This …

Co-Infection Of Zika And Dengue Virus In Aedes Aegypti And Aedes Albopictus Mosquitoes, Felicia Vazquez

Theses and Dissertations

The term co-infection describes an event when multiple pathogens infect a single host. For vector-borne diseases, a vector may become co-infected by feeding either on a single host that has multiple pathogens or feeding multiple hosts, each of which may be infected. Co-infection in non-vector hosts has been shown to influence immune response and eventual outcome of disease, and is likely to have a similar impact on vector species. With multiple vector-borne diseases circulating in South Texas, the potential for co-infection exists. We examined when mosquitoes are infected with one virus and subsequently infected with another. We hypothesized that the …

The Influence Of Task Type On Speech Production By Second Language Learners Of German: An Electropalatographic Study, Elizabeth Cope

Theses and Dissertations

Electropalatography (EPG) is a computer-based system that tracks and measures contact patterns between the tongue and palate during speech production. The present study is focused on how the lingua-palatal contact patterns of native English speakers learning German as a second language (L2) differ as a function of task type. The fricatives ich-Laut [ç] and ach-Laut [x] were used as the target sounds, placed in nonsense words, short sentences, and spontaneous speech. The productions of the fricatives in the varying speech tasks were gathered from 12 university students enrolled in their second semester of a university level course of German. Comparisons …

Planar Linear Ion Traps With Microscale Radii For Portable Mass Spectrometry, Trevor Keith Decker

Theses and Dissertations

Radio frequency (RF) ion traps based on the quadrupole device developed by Paul and Steinwedel utilize a dynamic electric field to spatially confine the trajectory of charged particles and may be employed as mass spectrometers by selectively ejecting trapped molecules based on the mass to charge ratio. Because of the inherent sensitivity and specificity of this process, ion trap mass spectrometers have become a popular scientific instrument. In the past two decades there has been a push to develop portable ion trap mass spectrometers for in situ mass analysis by geometrically scaling traps to smaller sizes. This decreases the power …

5d Grain Boundary Characterization From Ebsd Microscopy, Akash Savio Amalaraj

Theses and Dissertations

Knowledge of the full 5-degree Grain Boundary Character Distribution (GBCD) is vital to understanding properties, such as gas diffusivity, that are dominated by grain boundary character. Surface characterization techniques, such as Electron Backscattered diffraction (EBSD), can provide only 4 of the 5 GB characteristics (the rotation between the neighboring grains, and the trace of the GB on the surface). The inclination of the GB in the direction normal to the surface is not known. A previous study indicated that the GB inclination could be recovered by correlating the Electron Backscattered patterns (EBSPs) of sample points near the GB with EBSPs …

Development Of A Self-Powered Structural Health Monitoring System For Transportation Infrastructure, Aydin Karsilaya, Samer Dessouky, Athanassios Papagiannakis

Publications

Roadways and bridges play an important role in the economic and social health of society by connecting commerce and people. Economic growth and population expansion pose considerable burden on the aging infrastructure (i.e., pavements and bridges). There is a pressing need to develop structural health monitoring (SHM) technologies capable of collecting infrastructure utilization data. Doing so inexpensively with self-powered systems will revolutionize infrastructure monitoring technology, and will improve decision making enabling roadway and bridge preservation. In this study, a self-powered battery-less structural health monitoring (SHM) system was developed. It is powered by a thermal energy harvester equipped with thermoelectric generators …

Recruiting, Retaining, And Promoting For Careers At Transportation Agencies, Christofer Harper, Susan Bogus, Raghava Kommalapati, Doeun Choe

Publications

State transportation agencies currently face complex challenges in recruiting and retaining the workforce necessary to function effectively. The situation exacerbates due to the number of employees from different generations that have to coexist with varying values, expectations, and principles. These agencies are primarily comprised of two generational groups: the baby-boomers, who are approaching retirement and occupy many managerial positions; and the millennials, who are demonstrating their interest in technology and demanding dynamism in their careers. This multiplicity of interest represents a challenge for human resources (HR) in addressing workforce issues and providing the necessary means to recruit and retain qualified …

All That Glitters Is Not Gold: Media Coverage Of The Golden State Killer, Lasherica Thornton

Honors Theses

This thesis focused on the media’s extensive coverage of serial killers and, thus, how it could propel them to a state of fame. It discusses that no matter a serial killer’s circumstance, the media typically finds a story. For example, a serial killer can be on a rampage or can be dormant, but in subsequent stories, the media will center a story around the killer’s first and/or recent crimes, his identity, or his possible next move. The New York Times and Los Angeles Times coverage of the Golden State Killer frames the analysis of this manuscript. The purpose was to …
