Contribution Of The Pacific Decadal Oscillation To Global Mean Sea Level Trends, B. D. Hamlington, R. R. Leben, M. W. Strassburg, R. S. Nerem, K-Y. Kim

CCPO Publications

Understanding and explaining the trend in global mean sea level (GMSL) have important implications for future projections of sea level rise. While measurements from satellite altimetry have provided accurate estimates of GMSL, the modern altimetry record has only now reached 20 years in length, making it difficult to assess the contribution of decadal to multidecadal climate signals to the global trend. Here, we use a sea level reconstruction to study the 20 year trends in sea level since 1950. In particular, we show that the Pacific Decadal Oscillation (PDO) contributes significantly to the 20 year trends in GMSL. We estimate …

Extracting Tidal Variability Of Sea Ice Concentration From Amsr-E Passive Microwave Single-Swath Data: A Case Study Of The Ross Sea, Stefanie Mack, Laurie Padman, John M. Klinck

CCPO Publications

The periodic divergence of stress applied by ocean tidal currents to sea ice affects the time-averaged ice concentration (C_ice) and heat and freshwater fluxes at the ocean surface. We demonstrate that, at sufficiently high latitudes, tidal variability in C_ice can be extracted from single-swath data from the Advanced Microwave Scanning Radiometer–EOS (AMSR-E) satellite passive microwave sensor, although time intervals between swaths are irregular. For the northwest Ross Sea where tidal currents are large, tidal divergence is the dominant cause of C_ice variability in winter, with a range of ±0.2 about a mean of ~0.8. Daily-averaged C …

Intrusion Of Warm Surface Water Beneath The Mcmurdo Ice Shelf, Antarctica, A. A. Stern, M. S. Dinniman, V. Zagorodnov, S. W. Tyler, D. M. Holland

CCPO Publications

A 6 month temperature record collected below McMurdo Ice Shelf in 2011-2012 shows the temporal and spatial structure of the summertime warm water signal that penetrates beneath the ice shelf. The strength and duration of the warm water intrusion suggest an annual melt rate at Windless Bight of 0.71 m/yr. A Ross Sea numerical model demonstrates a seasonal warm water pathway leading from the west side of the Ross Sea Polynya (RSP) toward McMurdo Sound. The warm water enters McMurdo Sound, subducts beneath the ice shelf and causes accelerated summer melting. Temperature data were recorded using Distributed Temperature Sensing fiber …

Til Recession Do Us Part: Booms, Busts, And Divorce In The United States, Abdur Chowdhury

Economics Faculty Research and Publications

A general hypothesis regarding the impact of permanent income levels and business cycle fluctuations on divorce rate at the state level in the United States is analysed in this article. Based on the data for 45 states over the sample period of 1978–2009, it is shown that the higher the level of transitory income, the higher the incidence of divorce. In other words, divorce is pro-cyclical.

Second Language Learnerhood Among Cross-Cultural Field Workers, Thor Andrew Sawin

Theses and Dissertations

This dissertation studies second language learnerhood (ideologies about why and how to acquire a target language) among American field workers of a multinational, faith-based development organization, "Love the World". This organizational ethnography is longitudinal, tracking how learnerhood changes across the first years of field service. It is also multi-sited, tracing learnerhood across an assemblage of interconnected nodes. Field workers' learnerhoods are shaped by two larger ideologies of language learning which interact across the nodes of and individual trajectories through Love the World. One ideology, rooted in academic tradition, developmental second language acquisition and modernist missiological theory, valorizes the individual learner …

Tidal Variability Of Waves And Currents On A Caribbean Barrier Reef, Chelsea Wegner

Theses and Dissertations

The modern framework of Caribbean coral reefs is a product of resilient structures that have survived extreme variations in sea level for the past 18,000 years. However, the added influences of anthropogenic pressures, including ocean acidification, overfishing, pollution and bleaching make the future response to sea level rise uncertain. Carbonate production in the Caribbean is no longer at these historic rates and reefs may not be able to keep pace with the projected increases in sea level. This could have dramatic impacts on the hydrodynamics in coral reef environments, as reef morphology strongly influences these processes. Coral reefs are regarded …

Spectral Analysis Of Randomly Generated Networks With Prescribed Degree Sequences, Clifford Davis Gaddy

Theses and Dissertations

Network science attempts to capture real-world phenomenon through mathematical models. The underlying model of a network relies on a mathematical structure called a graph. Having seen its early beginnings in the 1950's, the field has seen a surge of interest over the last two decades, attracting interest from a range of scientists including computer scientists, sociologists, biologists, physicists, and mathematicians. The field requires a delicate interplay between real-world modeling and theory, as it must develop accurate probabilistic models and then study these models from a mathematical perspective. In my thesis, we undertake a project involving computer programming in which we …

Applications Of The Lopsided Lovász Local Lemma Regarding Hypergraphs, Austin Tyler Mohr

Theses and Dissertations

The Lovász local lemma is a powerful and well-studied probabilistic technique useful in establishing the possibility of simultaneously avoiding every event in some collection. A principle limitation of the lemma's application is that it requires most events to be independent of one another. The lopsided local lemma relaxes the requirement of independence to negative dependence, which is more general but also more difficult to identify. We will examine general classes of negative dependent events involving maximal matchings of uniform hypergraphs, partitions of sets, and spanning trees of complete graphs. The results on hypergraph matchings (together with the configuration model of …

Atmospheric Patterns And Asian Typhoon Landfalls, Ivetta Abramyan

Theses and Dissertations

The Western North Pacific Ocean (WNP) produces more frequent and intense tropical cyclones (TC) than anywhere else in the world, and these storms greatly impact society. This study examines synoptic scale atmospheric patterns and their effects on landfalling typhoons in Japan, Taiwan and Vietnam using composite analysis at upper and mid-levels of the atmosphere, as well as analyzing teleconnection impacts on tropical cyclone frequency, duration and intensity.

Examined Best Track data (1946-2010) shows an increased likelihood of Taiwan landfalls earlier in the season, Japan landfalls mid-season, and Vietnam landfalls towards the end of the typhoon season. The formation locations also …

Made In Japan: Kumi-Daiko As A New Art Form, Anna Marie Viviano

Theses and Dissertations

Japanese taiko ensemble drumming, known in Japan as kumi-daiko, is an art form that has only taken shape within the past fifty years. This new performance style involving taiko seems, on the surface, to have much in common with traditional Japanese court and theater music, regarded by scholars as the art music of Japan. Using drums that have a long history in Japan, however, does not necessarily make that ensemble part of ancient Japanese tradition. By studying the most famous groups in Japan, such as Kodo, it is easy to discern that kumi-daiko has many different inspirations, but is not …

Conrad Susa's Discovery And Praises: A Conductor's Guide To Performance Considerations, Keith Harry Walker

Theses and Dissertations

Conrad Susa (b. 1935) is an American composer who has contributed over thirty choral works that are of high quality incorporating texts written by well-known literary figures. His choral works are usually spiritual in nature though not strictly liturgical. Discovery and Praises is a presently unpublished cantata in four movements for mixed chorus, solos for two sopranos, an alto, a tenor, and a baritone. The accompaniment is scored for organ, harp, percussion, flute and handbells. Susa chose to set ancient poetry by Caedmon, Wipo of Burgundy, John Donne, and St. Patrick. Although the piece was composed in 1966 and revised …

Prevention Of Skin Breakdown In The Pediatric Intensive Care Unit, Lydia H. Palmer

Theses and Dissertations

Skin breakdown occurs when one or more layers of the skin have been disrupted (McLane et al., 2004; National Pressure Ulcer Advisory Panel, 2007). While some literature uses the terms skin breakdown and pressure ulcer interchangeably, these are actually two distinct conditions and pressure ulcers are encompassed in the definition of skin breakdown (Kuller, 2001; Lund, 1999; Suddaby et al., 2006). The consequences of skin breakdown in the pediatric population can include increased cost of treatment, infection, increased morbidity and mortality as well as psychological consequences from resulting alopecia or scarring (Schindler, 2010; Willock & Maylor, 2004). Development of skin …

William, Allison Marie Mcnutt

Theses and Dissertations

William is a novel that examines the lives of a pair of protagonists who are separated by approximately three hundred years of history. Liam is a modern history PhD who studies the colonial south, specializing in the years immediately following the pioneering period of Carolana rice cultivation around the turn of the eighteenth century; this is the middle ground after survival in the colony was largely secured, but when social hierarchies and racial allegiances were still in flux as the cash crop best suited to the coastal settlements had only just been discovered. Will is Liam's historical counterpart and lives …

"Makin' It": A Study Of First Generation College Graduates Lives Out Of Poverty, Sharla Benson-Brown

Theses and Dissertations

Scholars across various disciplines concur that poverty , especially when experienced generationally, is difficult to escape (MacLeod, 2009; Bowles & Gintis, 2002; Nieto, 2005; Corak, 2006; Sawhill & Haskins, 2008). Yet, while much is known about the existence and persistence of poverty, we know less about how and why those individuals who successfully escape poverty are able to do so (Hardaway & McLoyd, 2009).

Guided by critical social and institutional theory this qualitative study, examined the experiences of individuals who grew up in generational poverty (with parents who had no high school diploma), yet became first-generation college graduates, and entered …

Perceptions Of Breast Cancer-Related Stigma And Genetic Knowledge Among Latina Women: El Mejor Entendimiento Del Miedo., Jade Cognetti

Theses and Dissertations

Purpose: Breast cancer is the leading cause of cancer death among Latina women, with BRCA1/2 gene mutations accounting for a commensurate proportion of breast/ovarian cancer in Latina women as compared to non-Latina women. Despite this statistic, it has been shown that Latino populations exhibit low awareness and use of genetic services and that they hold culturally-related beliefs which stigmatize cancer. We hypothesized that a simple, culturally-tailored educational flier would improve genetics knowledge as well as decrease breast cancer-related stigma among Latina women in our sample. Method: Two groups of Latina women (N = 19) were provided with a pre-survey, educational …

A Geographic Modeling Framework For Assessing Critical Infrastructure Vulnerability: Energy Infrastructure Case Study, Leanne Sulewski

Theses and Dissertations

Vulnerability of critical infrastructure systems is of the utmost importance to a nation's national security interests, especially the electric grid. Despite the importance of these systems, disruptions continue to occur at an alarming rate, thus indicating that there is a fundamental flaw in the way critical infrastructure systems are analyzed for vulnerability.

Critical infrastructure systems are typically analyzed using mathematical approaches such as graph theory, which strip systems of their important geographic information, and only look at their connections to each other. While these relationships and metrics provide useful information, they cannot provide the entire picture. As such, this research …

Subsurface Imaging And Petrophysical Analysis Of The South Georgia Rift Basin, South Carolina, Olusoga Martins Akintunde

Theses and Dissertations

The Triassic-Jurassic South Georgia Rift (SGR) basin, buried beneath Coastal Plain sediments of southern South Carolina, southeastern Georgia, western Florida, and southern Alabama, consists of an assemblage of continental rift deposits (popularly called red beds), and mafic igneous rocks (basalt flows and diabase sills). The red beds are capped by basalts and/or diabase sills, and constitute the target for supercritical CO2 storage as part of a Department of Energy funded project to study feasibility for safe and long-term sequestration. This study addresses key stratigraphic, structural and petrophysical issues critical to determine subsurface suitability for CO2 storage as well as improved …

Amplitude Vs. Offset Effects On Gas Hydrates At Woolsey Mound, Gulf Of Mexico, Walter R. Anderson

Theses and Dissertations

Due to the estimated massive quantities of natural methane hydrates, they represent one of the largest sources of future alternative energy on Earth. Methane hydrates have been found in the shallow sub-seafloor of the Northern Gulf of Mexico where the water depth is in excess of ~900 m. Mississippi Canyon Block 118 has been chosen by the Gulf of Mexico Hydrates Research Consortium to be the site of a multi-sensor, multi-discipline sea-floor observatory for gas hydrate research. First evidence for gas hydrates at MC 118 was observed at Woolsey Mound. Subsurface evidence for gas hydrates has subsequently been substantiated by …

Understanding Online And Offline Sex Seeking Behavior Among Young Men Who Have Sex With Men: Implications For Hiv/Aids Interventions, Winston Eromosele Abara

Theses and Dissertations

Men who have sex with men (MSM), especially in the southeastern US are disproportionately impacted by the HIV/AIDS epidemic. Young MSM and African American MSM are particularly burdened accounting for a greater proportion of HIV/AIDS diagnoses. Factors such as risky sexual behavior, perception of sexual risk, ignorance about HIV sero-status, internalized homonegativity/homophobia (IH), stigma, and alcohol and illegal drug use have been advanced as reasons for this disproportionate burden. HIV/AIDS prevention efforts aimed at stemming the epidemic among MSM have focused on locations where MSM meet other men for sex such as parks, beaches, bathhouses, adult book stores, clubs, and …

Smokers' Neurological Responses To Imagery From Cigarette Package Warning Labels, Johann Fridrik Fridriksson

Theses and Dissertations

Tobacco use is the leading cause of preventable death in the United States. The Family Smoking Prevention and Tobacco Control Act was signed into law in 2009 and gave the U.S. Food and Drug Administration (FDA) the authority to implement pictorial health warning labels (HWLs) on cigarette packages. Multiple studies investigating self-reported affective, cognitive and behavioral impacts of HWLs suggest that the most effective warnings include imagery that depicts physical damage to the body due to smoking. However, self-report methods of assessment used in these studies may be biased. Far less is known about how HWLs directly modulate brain activity. …

Association Between Breastfeeding And Infant Growth: A Probable Reverse Causality, Shraddha Vyas

Theses and Dissertations

Background: Much conflicting results exist in the association between breastfeeding and infant growth. One of these confusions is related to the temporal sequence between breastfeeding practice and infant growth.

Objective: This study aimed at examining the association and investigating a possible reverse causality between breastfeeding and infant growth.

Method: Infant Feeding Practices Survey II, a national longitudinal database with repeated measurements, following women prenatally and until one year postpartum (N=2914) was used. Mixed linear model assessed the impact of breastfeeding from the 2nd, 4th, 6th and 9th months on infant growth at the 3rd, 5th, 7th and 12th months, respectively. …

Divine Discontent: Nathan Carter Newbold, White Liberals, Black Education, And The Making Of The Jim Crow South, Barry Malone

Theses and Dissertations

In the first half of the twentieth century, a small but vocal group of white southerners believed it possible to protect the flanks of the South's caste system by dampening black impatience with Jim Crow. Nathan Carter Newbold, a white racial moderate and State Agent for Negro Education, became a leading voice for the 'equalization without social equality' movement. Newbold believed blacks accepted the separation of the races as natural and beneficial to both, but they also expected whites to deliver equality of opportunity. The failure to meet this responsibility led blacks to engage in political and judicial activism. This …

Taking Oaths And Giving Thanks: Ritual And Religion In Revolutionary America, Tara E. Strauch

Theses and Dissertations

This dissertation examines the early modern ritual traditions of oaths, thanksgivings, and fast days in Revolutionary America and argues that American politicians and citizens negotiated the meanings of these rituals for American citizenship throughout the Revolutionary era. Oaths of office and allegiance, thanksgivings and fast days were tools for creating a united nation, but they also posed significant challenges because of the religious and political associations inherent in such rituals. These rituals came out of early modern Europe's religious and political culture which was useful for establishing America as a legitimate European nation. As colonials on the edge of the …

Evaluating The Intentionality Of Identified Misstatements: How Perspective Can Help Auditors In Distinguishing Errors From Fraud, Erin L. Hamilton

Theses and Dissertations

According to Auditing Standard No. 14, fraud is an intentional act. Thus, when a misstatement is identified during the audit, auditors should consider whether the misstatement might have been caused intentionally (PCAOB 2010a). The objective of the present study is to investigate whether considering the perspective of the manager responsible for a misstatement's occurrence impacts auditors' beliefs concerning the misstatement's intentionality. Using an experiment with 82 audit manager and senior manager participants, I find that auditors who actively consider the perspective of the manager who caused a misstatement assess the likelihood that the misstatement is intentional higher when the circumstances …

Policing Alcohol And Related Crimes On Campus, Andrea Nicole Allen

Theses and Dissertations

Research shows that college students drink alcohol frequently and heavily. This can compromise their health and well-being. Student drinking is also tied to crime. While prior work explores the nature and extent of crimes involving alcohol on campus, to date no study has examined how police handle these incidents or crime generally. This study fills that gap in the literature. Qualitative and quantitative data were collected by observing and interviewing campus officers at a large Southeastern university as they navigated through encounters with citizens. Findings include the following. Officers handle a variety of crimes, and do not have a single-faceted …

The Law Of The Body, Meredith M. Render

Emory Law Journal

In the absence of clarity about the legal status of the human body, courts have constructed a collection of circumstantially defined categories for resolving the question of human body ownership and use. This patchwork approach is awkward, unwieldy, incoherent, and, by many lights, ultimately unjust. Many able minds have been applied to critiquing the distributive consequences of a regime in which we cannot-at any point in our lives-"own" our own bodies (or its constituent parts), but other people can and do. But what has been missing from these conversations is a conceptual foundation for understanding the living human body as …

Quantitative Legal Prediction--Or--How I Learned To Stop Worrying And Start Preparing For The Data-Driven Future Of The Legal Services Industry, Daniel Martin Katz

Nowhere: Blank Verse Concerning Small-Town Life In California, Daniel Scarpa

Master's Theses

I wanted to explore the process of using place - specifically, small towns in California that I visited - as inspiration for the writing of a book of poetry. This has been done in the past, most notably by poets such as Kenneth Rexroth and Gary Snyder. I was inspired by these poets and several others and my own experience in these often overlooked small towns to create a collection of syllabic blank verse poems that touch on their economies, practical reasons for isolation, and unique micro-cultures. While on the whole, I am pleased with the way the collection turned …

Le Déchirement Et Le Châtiment De Soi Dans Épaves De Julien Green Et La Chute D'Albert Camus, Imene Aggoun

Master's Theses

This thesis explores how the paths of Julien Green and Albert Camus cross through Épaves and La Chute, when their characters question who they are and what they have become. This study analyzes not only existentialist philosophy, but various other factors such as the authors' biography, literary criticism, and psychoanalysis to understand how Philippe in Épaves and Clamence in La Chute suffer the consequences of an absurd world. Based on the authors' biographies highlighting the common link with other nineteenth century writers, one can confirm Green's saying that the work arises from a "domestic crisis." The study exposes an absurd …

The Pittsburgh Courier: Advocate For Integration Of The U.S. Armed Forces (1934-1940), Shelly Lynette Watson

Master's Theses

This study is a quantitative and qualitative content analysis designed to determine how the Pittsburgh Courier reported the issue of African-American military participation and integration of the U.S. Armed Forces prior to World War II and how that news coverage changed over time. The researcher analyzed 368 news items from 312 weekly editions of the Courier published between September 1, 1934, and September 21, 1940. The researcher compared news content across two periods within the time range specified for the study. The researcher found that the Courier consistently and extensively reported on the issue during the time period. The Courier …
