Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam

Master's Theses

In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four artificial reefs representing high and low profile structures in summer 2011. Colonized benthic biota were quantified …

"Black And White Together, We Shall Win": Southern White Activists In The Mississippi Civil Rights Movement, Olivia Bethany Moore

Master's Theses

During the Civil Rights Movement, Mississippi has often been characterized as a simple battle of white racists against black activists. Drawing heavily on oral histories, personal publications, and Mississippi Sovereignty Commission reports, this thesis examines the unconventional stories of white southerners who transcended the segregationist environments in which they were born. As southern white activism took many forms, this work offers biographical insights to three individuals who have received little scholarly attention: journalist P.D East, National Association for the Advancement of Colored People (NAACP) activist Buford Posey, and William Carey president Ralph Noonkester. While their contributions between 1950-1971 differed, being …

The Poet's Corpus: Memory And Monumentality In Wilfred Owen's "The Show", Charles Hunter Joplin

Master's Theses

Wilfred Owen is widely recognized to be the greatest English “trench poet” of the First World War. His posthumously published war poems sculpt a nightmarish vision of trench warfare, one which enables Western audiences to consider the suffering of the English soldiers and the brutality of modern warfare nearly a century after the armistice. However, critical readings of Owen’s canonized corpus, including “The Show” (1917, 1918), only focus on their hellish imagery. I will add to these readings by demonstrating that “The Show” is primarily concerned with the limitations of lyric poetry, the monumentality of poetic composition, and the difficulties …

Choros N. 10 By Heitor Villa-Lobos: Analyzing The Themes And Compositional Techniques Of Brazilian Modernism, Andre Oliveira Campos-Neto

Master's Theses

Heitor Villa-Lobos (b. March 5, 1887 - d. November 17, 1959) can be considered the most important composer in Brazilian music history. Although the composer is listed as one of the most influential composers in the history of the guitar, he reached his peak in his works for piano and symphonic groups. Works such as A Prole do Bebê (1 and 2), and the series of Chôros, came out during an extremely convoluted time, where Brazilian artists engaged in seeking an artistic representation of a unique Brazilian identity. Those works not only satisfied the hunger, but pushed the movement …

Are Countries In Environmental Cooperation Concerned About Relative Gains?, Vivian Chinua Olivia Ike

Master's Theses

A country’s decision to join or withdraw from environmental cooperation has been argued by interest based theories to be influenced by the economic cost of international agreements, national interest of countries and the free-rider problem. However, this thesis argues that relative gains is a more decisive factor that influences the decision of countries in international arrangements. It hypothesizes that countries in environmental cooperation are concerned about relative gains. A content analysis of the statements of fifteen countries in international climate change cooperation are analyzed. The countries include the United States, Russian Federation, Canada, Japan, Australia, China, Brazil, South Africa, India, …

The Invisible People Of The Invisible Coast: The Resilience Of People Experiencing Homelessness To Disasters On The Alabama, Louisiana, And Mississippi Gulf Coasts, Nicole Elizabeth Callais

Master's Theses

While extensive research has been conducted on vulnerability and resilience with regard to hazards, very few studies have researched the resilience of homeless populations. The Gulf Coast region is densely populated and susceptible to natural and anthropogenic hazards. Climate change studies indicate that this region will experience an increase in severe and intense tropical cyclones[1], thereby increasing the risk of experiencing adverse impacts from future coastal hazards. While local government agencies in this region have policies in place to protect communities, these policies tend to exclude any action regarding the evacuation and safety of the homeless population.

Shaken, Not Stirred: Espionage, Fantasy, And British Masculinity During The Cold War, Anna Rikki Nelson

Master's Theses

This project seeks to define and explore the development of Cold War British masculinity and national identity in response to decolonization. Following World War II, Great Britain experienced a time of political and cultural rebuilding. This project argues that following World War II, Britain had to renegotiate gender and national identity within the context of decolonization, the rise of the welfare state, and Britain’s diminished role in global politics, and the tensions within gender and national identity were expressed in Britain’s interest in espionage narratives both real and fictionalized. British spy novels by Ian Fleming, Desmond Cory, and John Le …

Growth And Reproduction Of Southern Flounder (Paralichthys Lethostigma) In The North-Central Gulf Of Mexico, Morgan Marie Corey

Master's Theses

Southern Flounder Paralichthys lethostigma is the most commonly harvested flatfish in the north-central Gulf of Mexico (GOM) and supports a major inshore recreational fishery, yet knowledge of the species’ life history is greatly limited. The objective of this research was to describe the growth and reproduction of Southern Flounder in the Mississippi stock. Fish were collected during September 2014 to March 2016 using primarily recreational fishing techniques. Otoliths (n = 313) were sectioned to estimate age, and multiple length-at-age models were fit to total length (TL, mm) and age estimate (y) data. Gonadal tissue samples (n = 221) …

Mr. Jefferson's Army In Mr. Madison's War: Atrophy, Policy, And Legacy In The War Of 1812, David Alan Martin

Master's Theses

President Thomas Jefferson is a well-known figure, who is not well understood. His military policies are under-examined in the historiography. Yet, he had a tremendous impact on martial development in the Early Republic. Jefferson reshaped the military to suite his pragmatic republican ideals. His militia system expanded while the regulars were disbanded. The Navy was greatly decreased, and the remainder of his military was used for frontier exploration, riverine trade, road development, and other public works. This disrupted the precedent of strong federal military development as set by his predecessors: George Washington and John Adams. His reforms also left the …

Correlation Of Polymer Performance And Hansen Solubility Parameters, Daniel Jobse Mania

Master's Theses

Ready-to-use (RTU) grout is becoming more important to the finish and remodeling construction industry. Market research shows it is a fast-growing product that not only is creating its own space, but is beginning to supplant existing technology.

The original intent of this research was to investigate formulation parameters and how they affect grout performance. It was learned that particle size and oil absorption (OA) value are important filler properties that affect performance as much as adequate packing density and optimal pigment volume concentration (PVC) without going beyond critical PVC (CPVC).

Polymer architecture was also determined to be extremely important, but …

Effects Of Experimental Noise Exposure On Songbird Nesting Behaviors And Nest Success, Tracy I. Mulholland

Master's Theses

Anthropogenic noise is an increasingly prevalent global disturbance. Animals that rely on the acoustical environment, such as songbirds, are especially vulnerable to these sounds. Traffic noise, in particular, overlaps with the frequency range of songbirds, creating masking effects. We investigated the effects of chronic traffic noise on provisioning behaviors and breeding success of nesting western bluebirds (Sialia mexicana) and ash-throated flycatchers (Myiarchus cinerascens). Because anthropogenic noise exposure has the potential to interrupt parent-offspring communication and alter vigilance behaviors, we predicted that traffic noise would lead to changes in provisioning behaviors, such as fewer visits to the …

Decolonizing The Ya North: Environmental Injustice In Sherri L. Smith’S Orleans, Micah-Jade M. Coleman

Master's Theses

Young Adult (YA) dystopias, in recent years, have imagined a future world fueled by the overuse and misuse of technology, the advancement of science for human gain, as well as societies ruled by governments that govern based on their own self-interests and economic gain. Such novels have opened the door for discussion about how the present-day actions of societies can impact the future of the environment; yet many only focus their attention on societies in the North— regions considered “developed” by the western world. In her YA novel, Orleans (2014), Sherri L. Smith focuses attention on the aftermath of Hurricane …

Prejudice And Discrimination In U.S. Graduate Geography Programs: Reports From Domestic And International Students, Karen C. Johnson

Master's Theses

This thesis focuses on domestic and international students and their experiences of discrimination and prejudice while enrolled in graduate geography programs in the United States. This is an issue that relates to three important and interrelated trends in graduate education in the United States: increasing numbers of international students; growing efforts to reduce and eliminate discrimination and prejudice in higher education; and rising awareness of the role that academic “climate and culture” play in sustaining or changing current patterns of participation by students of diverse backgrounds. A web-based survey was developed and used to collect data from 420 students in …

The Effects Of Nicotine On Conditioning, Extinction, And Reinstatement In Humans Using A Virtual Reality Conditioned Place Preference Paradigm, Alexandra N. Palmisano

Master's Theses

Despite an abundance of evidence illustrating the harmful effects of nicotine use, only a small percentage of users successfully quit (Messer et al., 2008). Moreover, current treatments for nicotine cessation produce only a slight increase in the likelihood of successfully quitting, which emphasizes the need for more effective strategies that facilitate smoking cessation (Hopkins et al., 2001). Several studies suggest that difficulty in controlling nicotine use behaviors results from nicotine’s ability to enhance the motivating function of cues associated with obtaining rewards. These studies indicate that it is of value to understand the behavioral and neuropharmacological mechanisms by which nicotine …

Supporting Emerging Multilingual Newcomer Students And Their Teachers In California Public High Schools, Rosa Lea V. Ojeda

The study examines research regarding deficit mindset that has led to student labels that perpetuate negative school and teacher views of culturally and linguistically diverse students. Additional research used for this study includes studies on what has been determined to benefit emerging multilingual students, as well as studies about the role of globalization and politics in the education of emerging multilingual and other culturally and linguistically diverse students. The study seeks to further the research on what changes in practice and mindset need to take place in the system …

Location Inference Of Social Media Posts At Hyper-Local Scale, Brian D. Mcclanahan

Master's Theses

This paper describes an approach to infer the location of a social media post at a hyper-local scale based on its content, conditional to the knowledge that the post originates from a larger area such as a city or even a state. The approach comprises three components: (i) a discriminative classifier, namely, Logistic Regression (LR) which selects from a set of most probable sub-regions from where 1 a post might have originated; (ii) a clustering technique, namely, k-means, that adaptively partitions the larger geographic region into sub-regions based on the density of the posts; and (iii) a range of techniques …

Whisk: Web Hosted Information Into Summarized Knowledge, Jiewen Wu

Master's Theses

Today’s online content increases at an alarmingly rate which exceeds users’ ability to consume such content. Modern search techniques allow users to enter keyword queries to find content they wish to see. However, such techniques break down when users freely browse the internet without knowing exactly what they want. Users may have to invest an unnecessarily long time reading content to see if they are interested in it. Automatic text summarization helps relieve this problem by creating synopses that significantly reduce the text while preserving the key points. Steffen Lyngbaek created the SPORK summarization pipeline to solve the content overload …

The "Creative Workspace": A Comparative Analysis Of Stakeholder Perceptions, Augustina Radziunaite

Master's Theses

The rise of information technologies and creative industries formed a new class of “creative knowledge workers” with special needs for a workspace design. The recent tendency of playful and bold workspace designs for creative industries was labeled by some researchers as a “creative workspace,” but a body of knowledge about design strategies supporting “creative knowledge workers’” performance is still limited.

This master’s thesis research attempts to define “creative workspace” design phenomenon based on the three main stakeholder groups’ perceptions. The research analyzes existing literature and conducts in-depth interviews with designers and users to collect the data and compare the findings. …

Parents' Involvement In Their Preschoolers Public Education: Families Of Children With And Without Disabilities, Lauren E. Racine

Master's Theses

Abstract

Parent involvement in early childhood education benefits the parents, the teachers, and most importantly the child. Parent involvement is a concept that refers to the participation of parents in their child’s development and academic learning, and is centered on the fostering of relationships between the home environment and the school environment (Fantuzzo, Tighe, & Childs, 2000). Currently, little research has been done on parent involvement in early childhood (and even less focusing on children with disabilities, specifically), and this study aims to fill this gap in the literature. Thirty nine parents of children enrolled in a public preschool program, …

The 2013 Boston Marathon Attacks: An Experimental Investigation Of Worldview Change Following Film Re-Exposure To Mass Trauma, Ian A. Gutierrez

Master's Theses

Models of meaning making and post-traumatic growth contend that traumatic events are catalysts for significant and long-lasting change in a person’s worldview—that is, their beliefs about social, metaphysical, theological, and political reality. Nearly all tests of this contention have employed retrospective and cross-sectional methods. However, the limitations inherent in these designs preclude causal conclusions. The current study represents the first longitudinal, laboratory-based experimental examination of belief change following trauma exposure using the trauma film paradigm. Findings reveal that the trauma film paradigm can successfully induce posttraumatic affective responses with live news coverage of a mass trauma (i.e., the 2013 Boston …

Lower Scotts Creek Floodplain And Habitat Enhancement Project, Benjmain O. Cook

Master's Theses

Scotts Creek, located in northern Santa Cruz County, maintains the southernmost persistent population of Central California Coast (CCC) Coho Salmon (endangered) in addition to CCC steelhead (threatened). Fisheries biologists believe overwinter mortality due to lack of refuge habitat is the primary factor limiting salmonid production. Instream rearing habitat may also be limiting, especially during drought years. The legacy effects of historic land use practices, including dredging, wood removal, and the construction of levees, continued to limit refuge and rearing opportunities. A restoration project was implemented to improve refuge and rearing opportunities for salmonids along lower Scotts Creek by removing portions …

Benefits Of Advanced Traffic Management Solutions: Before And After Crash Analysis For Deployment Of A Variable Advisory Speed Limit System, Alexander Lindsay Chambers

Master's Theses

Variable speed limit (VSL) systems are important active traffic management tools that are being deployed across the U.S. and indeed around the world for relieving congestion and improving safety. Oregon’s first variable advisory speed limit signs were activated along Oregon Highway 217 in the summer of 2014. The variable advisory speed system is responsive to both congestion and weather conditions. This seven-mile corridor stretches around Western Portland and has suffered from high crash rates and peak period congestion in the past. VSL systems are often deployed to address safety, mobility and sustainability related performance. This research seeks to determine whether …
