Towards Multi-Modal Data Classification, Henry Ng

UNLV Theses, Dissertations, Professional Papers, and Capstones

A feature fusion multi-modal neural network (MMN) is a network that combines different modalities at the feature level to perform a specific task. In this paper, we study the problem of training the fusion procedure for MMN. A recent study has found that training a multi-modal network that incorporates late fusion produces a network that has not learned the proper parameters for feature extraction. These late fusion models perform very well during training but fall short to its single modality counterpart when testing. We hypothesize that jointly trained MMN have weight space that is too large for effective training. To …

Public Perceptions Of Police Militarization: A Nuanced Understanding Of Public Support For Police Practices, Leobardo Lopez-Cristobal

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, there has been heavily publicized incidents of police use of military weapons and tactics, which has raised concerns regarding the militarization of police. More famously, in 2014, Ferguson police utilized military weapons and tactics to quell the masses after the police shooting of Michael Brown incited protests and riots. Despite an overall decrease in incidents of police use of force and deadly shootings, individual dramatic events of police militarization paint a picture of a militarized police force. This coincides with an overall increase in military equipment transfers (e.g., weapons, vehicles) to police agencies in the United States. …

How Consumers Assess Multiple Cues: The Role Of Dual Processing System On Hotel Booking Decisions, Eun Joo Kim

UNLV Theses, Dissertations, Professional Papers, and Capstones

An online travel agency (OTA) is an important channel for hotels to generate new reservations. To make booking decisions, people collect and evaluate available information. Hotels try to provide effective information to persuade customers to book their hotel deals; however, not all information is manageable by the hotels. This research evaluates the effects of information on OTA websites with an approach based on the origins of the information. Depending on the origin, multiple cues can be categorized by two types, controllable and uncontrollable cues. A controllable cue is information that hotels can maintain, whereas an uncontrollable cue is not manageable …

The Art Of 'Stick To Sports,' Politics, And Sports Media Industry Studies, Shi-Quan Nettingham

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis aims at unpacking the discourse of “stick to sports,” which audiences wield to police social and cultural boundaries and battles involving race, gender, and politics. The melding of sports and politics, primarily through social media platforms, riles up audiences resulting in arguments where larger social issues are deliberated and processed. The stick to sports discourse is used to dictate who can and can’t speak and what kinds of discussions are appropriate in relation to sports. The sports network ESPN is a site for understanding how corporations leverage this discourse and use it to claim political neutrality, while disciplining …

Shattering The Glass: Will Gen Z Bring Us Closer To Gender Equality In Us Hospitality Leadership?, Denise Holly Ramirez Molintas

UNLV Theses, Dissertations, Professional Papers, and Capstones

The continued underrepresentation of women in senior leadership positions has impaired the hospitality industry’s capacity to achieve the fifth UN Sustainable Development Goal of Gender Equality. Although the industry has initiated programs to establish gender parity, the innate gendering through traditional leadership prototypes and gender-role stratification requires investigation. Scholars have noted the limited focus on gender-aware issues in hospitality research. Further, as gender is a socialized construct, historical shifts in gender ideologies have enabled changes in gendering at the individual, interactional, and institutional dimensions of society. Grounded in gender as a social structure theory and role congruity theory, this dissertation …

A Hybrid Experimental-Numerical Study On The Flow Topology In The Confluence Hydrodynamics Zone Of An Open Channel With Lateral Drainage Pipe Discharge, Mohammad Nazari-Sharabian

UNLV Theses, Dissertations, Professional Papers, and Capstones

To avoid disrupting the flow in flood control channels with lateral drainage pipes, or impact channel capacity, confluences are constructed at small angles (Maximum 30○). These small angles are costly to construct, since they require more real estate than greater angles.

By performing several laboratory experiments in the Fluid Dynamics Laboratory of the University of Nevada, Las Vegas (UNLV) and utilizing a numerical model (FLOW-3D), this study investigated the impact of submerged lateral drainage pipe discharges into rectangular open channels, on flow topology in the confluence hydrodynamics zone (CHZ). This was done across a range of channel widths, flow rates, …

The Significance Of Mfd And Oxidative Damage In Stationary-Phase Mutagenesis In Bacillus Subtilis, Holly Anne Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

The process of stationary-phase mutagenesis, also known as adaptative or stress-induced mutagenesis, is a phenomenon where bacterial cells accumulate mutations in non-replicative conditions. This process has mainly been studied in Escherichia coli and Bacillus subtilis; however, the underlying mechanisms found in each of these systems differ. Here, I use B.msubtilis to study previously understudied aspects of stationary-phase mutagenesis. In this dissertation, I describe work that has led to three major discoveries which are described below.

First in B. subtilis, Mfd is important for stationary-phase mutagenesis and its mutagenic function at regions of the genome that are transcriptionally upregulated has been …

Synthesis And Characterization Of Synthetic Urban Melt Glass, Rebecca Kristien Lowe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Melt glass formed from the explosion of a nuclear device is a unique post-detonation material that can aid in the ensuing forensics investigation. Trapped in the melt glass are chemical and isotopic signatures that can provide diagnostic and source information about the weapon by comparison with documentation of previous detonations. A nuclear terrorist attack would likely take place in an urban environment and as such, the melt glass formed would consist of a complex matrix including urban materials like cement and glass, activation products from the large neutron flux that will be seen, and fission products from the detonation.

Investigation Of Acute Response To Carbohydrate In Subsequent Resistance Training, Damon Mccune

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resistance training has been shown to have several positive benefits to health including increasing muscle size and strength, reducing risk of sarcopenia with aging, and is associated with reduced risk of mortality. A cornerstone in accomplishing these goals is to progressively overload the muscle by increasing training volume to promote muscle protein synthesis following training stimulation. Total training volume has been demonstrated in the literature to be a prime determinant of muscle hypertrophy and overall training performance. Carbohydrate (CHO) manipulation has been observed as a potential ergogenic aid when training demands are high. Current research investigating nutrition related to exercise …

Beyond Maidens And Mothers: A Study Of Till We Have Faces, Tamar Peterson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines how C.S. Lewis’ final novel, Till We Have Faces, demonstrates a significant diversion from the author's typical writing habits, especially regarding his depictions of women. Progressing through the novel chronologically, this thesis studies sixteen notable scenes that demonstrate this diversion. It tracks the development and depiction of women characters who exemplify a more realistic, complex, egalitarian writing style—one that allows women to wield legitimate power, excel in military combat, operate as conduits to the Divine, and enjoy their sexuality in affirming ways.

This thesis begins with an introduction to Lewis' position as a lay theologian and popular …

Thatcherism In The Contemporary British Novel, 1978-2012, David Mowatt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Thatcherism in the Contemporary British Novel, 1978-2012

This dissertation reveals a nuance to contemporary British texts that have thus far been almost homogenously categorized as contributing to a negative portrayal of the political, cultural, and social policies of the 1980s. A study of texts and criticism of the contemporary British novel highlights the disproportionate number of depictions that could be considered anti-1980s and, as a representation of that decade, in turn anti-Thatcherite. There is an apparent consensus in the damaging effects on almost all aspects of British society during the decade because of the many policies enacted by the Thatcher …

The human immunodeficiency virus (HIV) infection is a global epidemic, with initial high mortality rates since the first diagnosis over three and a half decades ago. However, the use of antiretroviral therapy (ART) has led to longer, healthier lives for many people living with HIV (PLHIV). Accordingly, aging comes with associated co-morbidities like obesity, diabetes, and cardiovascular diseases. The purpose of this mixed-methods study was to further understand the emergent phenomenon of obesity and overweight among PLHIV who are on treatment with ART, using Nigeria as a case study.

An explanatory sequential mixed-method design was used that involved the analysis …

Management Of Atrial Fibrillation With Smartphone Technology, Teresa Praus

UNLV Theses, Dissertations, Professional Papers, and Capstones

Atrial fibrillation is the most common arrhythmia affecting over six million people; it is predicted to increase two-fold by the year 2050. This arrhythmia results in a lack of

atrial/ventricular communication, accompanied by ineffective atrial contraction, suboptimal ventricular filling, and thrombus formation. This may lead to stroke, and ultimately heart failure. The current economic burden related to the complications of atrial fibrillation is estimated to be greater than $6 billion annually with potentially catastrophic events, further increasing expenditure.

When patients experience symptoms related to atrial fibrillation, it is common for them to present to a hospital emergency department. These visits, …

The Use Of Female Permanent Contraception Among Women Desiring To Limit Childbearing In Sub-Saharan Africa: Analyses Of The Spatial Pattern And Individual- And Country-Level Determinants, Babayemi Oluwaseun Olakunde

UNLV Theses, Dissertations, Professional Papers, and Capstones

Female permanent contraception (FPC) is the most commonly used contraceptive method, globally. It is a convenient, safe, and cost-effective modern contraceptive method that permanently stops childbearing among women. Despite its benefits, previous reports suggest that the increasing proportion of women who desire to limit childbearing in sub-Saharan Africa (SSA) rely more on less effective contraceptive methods, predisposing them to unintended pregnancies and their associated consequences. This study aimed to add to the sparse body of evidence on the use of FPC and the associated determinants among women with demand for limiting childbearing in SSA. Using data from Demographic and Health …

Love In South Korea: Transformations Of Intimacy And Gender Relations In Korean Romantic Relationships, Alex Joseph Nelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Romantic love holds a central place in South Korean imaginaries, animating television dramas and pop ballads, but has been largely overlooked in Korea's ethnographic record. Drawing on data collected through 18 months of ethnographic fieldwork, survey research, interviews, and analysis of folklore, the present study investigates how South Koreans conceptualize romantic love, how those conceptions have changed over time, and the ways they are transforming with the Korean field of gender relations.

This study documents love's entwinement with marriage in South Korea. Koreans are developing companionate ideals of marriage that shift the focus of kinship from the parent-child relationship to …

An Alternative Approach To Food Market Design: Strategies That Nurture Human Health And Well-Being, Kendall Marsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Access to food is being implemented in newer and more convenient forms now more than ever before. However, many of the methods that people utilize to purchase food may have substantial adverse health effects. Markets were once centered around a direct exchange of locally grown food and intimate social gatherings. Major developments like the industrialization of agriculture, rapid urbanization, and technological advancements introduced a shift in food market settings. Redefining the design of the market environment can transform a routine task into a valuable experience that nurtures human health and well-being.

In addition to a review of literature, the method …

Rapid Evolution Of Starvation Resistance In Drosophila: Physiological And Molecular Mechanisms, Austin Joseph Mckenna

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Gibbs lab has maintained starvation-selected Drosophila melanogaster for >130 generations. These starvation-selected flies evolved an obese phenotype with a suite of physiological differences compared to control-fed flies. Previous studies have shown that long-term starvation-selected Drosophila contain more lipids, have lower metabolic rates and develop more slowly than controls. This dissertation encompasses 1) Examining the molecular mechanisms contributing to starvation resistance, 2) Functional validation of the candidate plin1 allele, and 3) Rapid physiological and genomic evolution in starvation-selected Drosophila.

Starvation-selected Drosophila survive starvation conditions much longer than control-fed flies. This study took a simple approach to identify possible differences in …
