Understanding How Intentionally Unplugging From Cell Phones Shapes Interpersonal Relationships And The Undergraduate College Experience, Jadelin P. Felipe

Master's Theses

The purpose of this study was to gain an understanding of what motivated college students—the Unplugged Students—to intentionally use their cell phones less and how they understood the impact that unplugging had on their interpersonal relationships and college experience. Nine undergraduate college students from four private schools were interviewed in one-on-one semi- structured interviews. These students, considered non-users, provided a particularly useful perspective as these students made a conscious choice to counteract social norms and experienced both being plugged in and unplugged. Cell phones and the act of unplugging proved to make up a complex and more nuanced topic than …

Master's Theses

This thesis investigates the complex and dynamic communicative relationship between beekeepers and their managed honey bee colonies, providing insight into the relationship between bees, their stewards, and the interface between nature and culture. It also helps unravel the ways in which this interspecies relationship changes a beekeepers’ perception of what it means to be human. Data collection features extensive participant observation with 21 semi-structured interviews with Southern beekeepers.

The interrelationship between communication and interaction, as well as diverse ways in which messages and cues manifest in the bee yard are explored through olfactory, optical, touch, and mechanical modalities. Variables including …

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.

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 …

"Your Reclamation”: The Gothic Child And Moral Restoration In Charles Dickens’S A Christmas Carol, Ashten Roberts

Master's Theses

Charles Dickens’s A Christmas Carol (1843), an example of Victorian Gothic literature, portrays spirits escorting Ebenezer Scrooge on a journey through time in order to transform him from a miser to a benefactor. Dickens’s text has received much critical attention, and while most critics agree that the novella includes various elements of the gothic, few draw attention to the possibility of the child characters as gothic elements. I argue that Carol’s child characters can be read in terms of what Margarita Georgieva calls “the gothic child.” According to Georgieva, the gothic child can be an adult’s memory from childhood …

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 …

Effects Of Prebiotics On Gut Bacterial Communities And Healing Of Induced Colitis In Mice, Krystyn Elizabeth Davis

Master's Theses

Inflammatory Bowel Diseases (IBD) cause chronic inflammation of the gastrointestinal tract and debilitating symptoms in those suffering from the diseases. After inducing colitis in a mouse model using Dextran Sulfate Sodium (DSS), prebiotics inulin and oligofructose enriched inulin (OEI) were used as treatments to determine their effects on the gut microbial community, physiological healing process, and immune response in the mice after initial inflammation and before subsequent inflammation, or relapse. The treatment with inulin led to an increase in regulatory T cell number, but this increase was not as significant as the increase induced by the OEI. Inulin increased the …

The Effects Of 4-Nonylphenol On The Immune Response Of The Pacific Oyster, Crassostrea Gigas, Following Bacterial Infection (Vibrio Campbellii), Courtney Hart

Master's Theses

Endocrine disrupting chemicals (EDCs) are compounds that can interfere with hormone signaling pathways and are now recognized as pervasive in estuarine and marine waters. One prevalent EDC in California’s coastal waters is the xenoestrogen 4-nonylphenol (4-NP), which has been shown to impair reproduction, development, growth, and in some cases immune function of marine invertebrates. To further investigate effects of 4-NP on marine invertebrate immune function we measured total hemocyte counts (THC), relative transcript abundance of immune-relevant genes, and lysozyme activity in Pacific oysters (Crassostrea gigas) following bacterial infection. To quantify these effects we exposed oysters to dissolved phase …

Fluid Flow Characterization And In Silico Validation In A Rapid Prototyped Aortic Arch Model, Alexandra Mariel Knauer

Master's Theses

Transcatheter aortic heart valve replacement (TAVR) is a procedure to replace a failing aortic valve and is becoming the new standard of care for patients that are not candidates for open-heart surgery [2]. However, this minimally invasive technique has shown to cause ischemic brain lesions, or “silent infarcts”, in 90% of TAVR patients, which can increase the patient’s risk for stroke by two to four times in future years [3]. Claret Medical Inc., a medical device company, has developed a cerebral protection system that filters and captures embolic debris released during endovascular procedures, such as TAVR. This thesis utilized CT …

The Preservation And Protection Of Native Biodiversity In The Guadalupe Nipomo Dunes Complex, Lindsey M. Whitaker, Matthew Ritter, Scott J. Steinmaus, Jonathan Hall

Master's Theses

The Guadalupe Nipomo Dunes Complex (GNDC) is located within the California Floristic Province, a biodiversity hotspot characterized by high rates of endemism and exceptional loss of habitat. In 1980, the US Fish and Wildlife Service described the GNDC as, “the most unique and fragile ecosystem in the State of California,” and ranked it first on a list of 49 habitat areas needing state protection. It is the largest coastal dune area in California and it is one of the last remaining, relatively intact ecosystems of its type and size in the western United States. The growing recognition of species decline …

Reconstitution Of Munc18-Dependent Mast Cell Degranulation, Matthew Grant Arnold

Master's Theses

Mast cells are specialized secretory leukocytes that play diverse roles in the body, mediated by release of histamine and other pharmacologically active substances. Although offering essential protection in innate and adaptive immunity, mast cells are also essential to the progression of inflammatory diseases, including allergy and asthma, (Theoharides et al., 2012). Exocytosis of pro-inflammatory mast cell mediators in response to otherwise innocuous antigens relies on evolutionarily-conserved membrane fusion machinery. These proteins, called SNAREs are regulated by the Sec1/Munc18 (SM) protein family (Axle Lorentz, Baumann, Vitte, & Blank, 2012). Mast cells express three mammalian Munc18 isoforms (a, b, and c), which …

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

Master's Theses

This study focuses supporting emerging multilingual newcomer students and their teachers. 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 …

Biomarkers Of Orthodontic Tooth Movement With Fixed Appliances And Vibration Device: A Randomized Clinical Trial, Marie-Claude Chouinard

Master's Theses

Biomarkers of orthodontic tooth movement with fixed appliances and vibration device: A randomized clinical trial

Marie-Claude Chouinard D.M.D.

ABSTRACT

Background: On average, comprehensive orthodontic treatments last approximately 21-27 months in non-extraction cases and 25-35 months when teeth elected for extraction. Longer treatment times have been associated with multiple detrimental effects such as white spot lesions, root resorption, gingival inflammation and dental caries. Recently, some evidence has shown that the application of mechanical vibration to the dentition can increase the rate of tooth movement. However, the biological mechanism underlying this effect is not clearly understood. The aims of this study were …

A Minor Necessity: Minor Splicing Is Required In Murine Limb Development, Christopher D. Lemoine

Master's Theses

Microcephalic osteodysplastic primordial dwarfism type-1 (MODI) is a rare congenital developmental disorder resulting in patients presenting with microcephaly, limb abnormalities, and growth retardation. This disease, along with the related Roifman Syndrome, results from mutations to the gene RNU4atac. This gene encodes for the U4atac small nuclear RNA (snRNA) which, along with four other snRNAs (U11, U12, U5, and U6atac) compose the small nuclear ribonucleoprotein (snRNP) complex called the minor spliceosome. Responsible for the excision of a subpopulation of introns (called minor introns), the minor spliceosome is known to play an essential role in eukaryotic limb development. However, while mutations in …

Serine Dipeptide Lipid And Prostaglandin E2 Recovery In Pulps And Tooth Apices: Relationship To Pulpal Status, Aniuska Tobin

Master's Theses

Introduction: Apical periodontitis is characterized by inflammation and destruction of the periapical tissues that is primarily caused by polymicrobial infection of the pulp, which is dominated by Gram-negative species. Gram-negative bacteria have different virulence factors, e.g. cell wall endotoxin and serine lipids, which are toxic to the periapical tissues leading to activation of the host immune response and inflammatory reaction. Porphyromonas endodontalis (P.endodontalis), a Gram-negative bacterium, has been shown to populate necrotic root canal systems and may contribute to apical bone loss. Moreover, it is shown to synthesize novel serine dipeptide lipid classes (Lipid 654 and Lipid 430). Lipid 654 …

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. …

The Effects Of A Uniformly Weighted Exercise Suit On Biomarkers Of Bone Turnover In Response To Aerobic Exercise In Postmenopausal Women With Low Bone Density, Haley Frances Terndrup, Alison K. Ventura, Todd Hagobian, Scott Hazelwood

Master's Theses

Current options for maintaining or slowing aging-related bone mineral density (BMD) loss in postmenopausal women primarily include pharmaceutical agents. More recently, physical activity and exercise have been suggested as highly effective, low cost alternatives. Weighted aerobic exercise, utilizing load carriage systems (LCS), is known to increase the gravitational forces impacting bone, creating a higher osteogenic stimulus than standard aerobic exercise. In response to the positive research on aerobic exercise with well-designed LCS, Dr. Lawrence Petrakis, MD, developed a unique 5.44 kg uniformly weighted exercise suit. This study aimed to examine the effects of the uniformly weighted exercise suit on serum …

An Analysis Of Anterior Mandibular Anatomy Using Cone Beam Computed Tomography: A Study Of Dentate And Edentulous Mandibles, Roberta A. Wright D.M.D.

Master's Theses

Statement of Problem: The anterior mandible has conventionally been deemed as a relatively “safe zone” for dental implants due to perceived lack of innervation to the area as well as its relatively thick cortices and dense bone. However, with the evolution of cone beam computed tomography (CBCT), a number of anatomic challenges have been identified by clinicians that can lead to neuropathy and life-threatening hemorrhage if violated. The three critical anatomic structures in this area that pertain to implant placement are the sublingual artery (SLA), submental artery (SMA), and the mandibular incisive canal. Currently, there is a lack of knowledge …

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, …
