Using Pictorial Action Instructions To Train Low-Literacy Adults To Construct A Basic Humanitarian Engineering Project, Kathleen Paco Cadman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Low- and middle-income countries (LMICs) are often disproportionately faced with environmental hazards, which can cause adverse health outcomes. Although humanitarian engineering projects have been created to mitigate these hazards, LMICs are also frequently impacted by literacy deficits, creating a barrier in training low-literacy individuals to construct these projects. The purpose of this dissertation was to develop, refine, and test the usability of pictorial action instructions (PAI) in training low-literacy individuals to construct a humanitarian engineering project. A concept analysis was completed, including the creation of an operational definition, for “lay worker health literacy.” This analysis and definition set a foundation …

Mixing The Business Of Pleasure: How Mixing Shaped The Labor And Narratives Of Female Entertainers In Mid-Twentieth Century America, Evan Maryl Casey

UNLV Theses, Dissertations, Professional Papers, and Capstones

In mid-twentieth century America, the practice of mixing – the required visibility of performers outside of their time on stage for an economic purpose – cut across the various genres of sexualized female labor, from showgirls to exotic dancers and the professional women who occupied the space between. Mixing required performers socialize with patrons, encouraging them to buy drinks and was expected of a wide variety of female professionals in the decades following the Second World War, including burlesque performers, gogo dancers, exotic dancers, and showgirls, hostesses, waitresses, and B-girls. Women’s bodies have historically been a part of a commercialized …

A Comparison Of The Product Topology On Two Trees With The Tree Topology On The Concatenation Of Two Trees, Katlyn Kathleen Cox

UNLV Theses, Dissertations, Professional Papers, and Capstones

A game tree is a nonempty set of sequences, closed under subsequences (i.e., if p ∈ T

and p extends q, then q ∈ T). If T is a game tree, then there is a natural topology on [T],

the set of paths through T. In this study we consider two types of topological spaces, both

constructed from game trees. The first is constructed by taking the Cartesian product of

two game trees, T and S: [T] × [S]. The second is constructed by the concatenation of two

game trees, T and S: [T ∗ S]. The goal of our …

The Effects Of A Retrieval Practice Intervention On Undergraduates’ Monitoring And Control Processes Using Performance Feedback In A College Classroom, Meganclaire Cogliano

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study examined the effects of a classroom intervention on students’ metacognitive monitoring of retrieval practice performance feedback and metacognitive control of future study decisions. The sample included 103 undergraduate students enrolled in five sections of an introductory educational psychology course. A true experimental design was used to randomly assign students to trained (n=49) and control (n=54) conditions within each section.

During the semester, students completed a pre- and post- metacognitive awareness inventory (MAI), 10 practice-tests, 10 feedback monitoring assignments, and a cumulative final examination. The feedback assignments required students to identify areas of mastery (i.e., well-learned topics) and …

Determination Of Anthropogenic Radionuclides In Ocean Water Using Extraction Chromatography, Jaimie Daum

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the aftermath of the reactor accident in Fukushima, it has become obvious that there is a severe lack in methods that would allow for the rapid determination of anthropogenic radionuclides in ocean water. Current radioanalytical techniques for the determination of radionuclides in natural waters have a number of disadvantages including the fact that they are time consuming, generate a substantial amount of waste, and are typically multi-step processes. Additionally, the elevated amount of dissolved ions in ocean water imparts a complex matrix that can interfere with the rapid separation and determination of anthropogenic radionuclides. Therefore, due to the size, …

Evaluating The Feasibility And Sustainability Of Direct Potable Reuse In Las Vegas, Nv, Cory Dow

UNLV Theses, Dissertations, Professional Papers, and Capstones

Community water sources are becoming more and more strained due to several factors including severe drought, population growth, urbanization, and climate change. This has spurred several water agencies to evaluate alternative water supply options to extend their resources. One potential alternative is potable reuse. Potable reuse comes in two forms: indirect potable reuse (IPR) and direct potable reuse (DPR). IPR is the advanced treatment of wastewater effluent before discharging into an environmental buffer that is a drinking water supply such as a lake, river, or groundwater aquifer before extraction and use. DPR is the advanced treatment of wastewater effluent that …

Exploring The Effectiveness Of Model-Based Instruction To Improve Sixth-Grade Students’ Science Content Knowledge, Scot D. Ewen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The economy of tomorrow is uncertain, so students today need to be prepared for the known and unknown careers that lie ahead. Currently, not all students are expected to have equal career opportunities based on evidence from dropout and testing data (Brown & Brown, 2007; Kirsch, Braun, Yamamoto, & Sum, 2007), so educators should consider different methods of helping all students reach their potential. Modeling instruction is one method that might help diverse learners improve their scientific understandings and allow them to pursue careers in technology-oriented fields. A quasi-experimental study was conducted with 128 sixth grade students as participants. A …

To Remain Near The "Water Ditch," Paiute Sovereignty And United States Settler Colonialism, Owens Valley, California, 1870-1937, Lee Murray Hanover

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis argues that Owens Valley Paiute sovereignty manifested itself both inherently and adaptively from 1870 to 1937. Sovereignty is an historically contingent term that reflects how nations deploy power to retain control over their communities and provide self-determination within economics, politics, culture, and society. This thesis illuminates Paiute sovereignty through the Peoplehood model, explaining how Paiute sovereignty existed at the moment of their creation, when Coyote placed them next to the Water Ditch—Owens River—and told them to spread throughout but never leave their homeland, the Owens Valley. This inherent mandate allowed Paiutes to adapt Coyote’s stipulation to remain in …

Power And Authority Of Royal Queen Mothers: Juxtaposing The French Queen Regent And The Ottoman Validé Sultan During The Early Modern Period, Reneé N. Langlois

UNLV Theses, Dissertations, Professional Papers, and Capstones

Women and their relationship to sovereignty, during the early modern era has become a rapidly growing topic, given that during this period an unprecedented number of women rose to high positions of power. This paper aims to compare the lives of the queen regents in France with their counterparts, the validé sultans in the Ottoman Empire, over the course of the sixteenth and seventeenth centuries, when both groups of royal women acquired substantial power. Although these women were prohibited from ruling in their own right, the paper explores the ways in which queen regents and validé sultans used both official …

Investigating The Role Of Liminality In The Cultural Transition Of The Late Eighth Millennium Bc On Cyprus, Levi Keach

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Near East has the earliest and best documented Neolithic in the world. However, most research attention has focused on the mainland. The spread of the Neolithic to the adjacent Mediterranean islands was once considered relatively late. The last three decades of research has changed this perception, demonstrating that the spread of the Neolithic to Cyprus was contemporary with its continental development.

This work addresses the change between the archeologically defined cultures of the Cypro-Pre-Pottery Neolithic B (Cypro-PPNB) and the Khirokitian Culture (KC) on the island of Cyprus between the 9th and 6th millennia cal BC. The purpose of this …

Fundamental Tradeoffs In Estimation Of Finite-State Hidden Markov Models, Justin Le

UNLV Theses, Dissertations, Professional Papers, and Capstones

Hidden Markov models (HMMs) constitute a broad and flexible class of statistical models that are widely used in studying processes that evolve over time and are only observable through the collection of noisy data. Two problems are essential to the use of HMMs: state estimation and parameter estimation. In state estimation, an algorithm estimates the sequence of states of the process that most likely generated a certain sequence of observations in the data. In parameter estimation, an algorithm computes the probability distributions that govern the time-evolution of states and the sampling of data. Although algorithms for the two problems are …

Breaking The Language Barrier: Equitable Assessment In General Chemistry, Eshani Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Because language provides the framework through which knowledge is constructed, it is crucial to consider the ways in which students with limited English proficiencies are able to express their understanding. English language learners (ELLs) make up a significant portion of the student body in the education system and represent many ethnic and racial minorities in STEM (Science, Technology, Engineering & Mathematics) fields (Burke & Mattis, 2007). Despite the national push to build a more diversified, STEM-ready workforce, there is little research that considers the way ELLs are assessed in STEM courses at the postsecondary level. Literature reports that science tests …

Nutrition Transition Of Hadza Foragers: Implications For Juvenile Behavior, Trevor Pollom

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Hadza foragers of Tanzania are undergoing early stages of nutrition transition and an increased level of market integration. Accompanying these shifts is a significant change in diet composition with greater access to maize, wheat, and other domesticated cultigens, even in the most remote bush camps. Despite the rapid rate of nutrition transition, few studies have attempted to quantify the possible effects this transition is having on Hadza diet or foraging behaviors. Here, we attempt to fill this gap in the literature by reporting results of a mixed methods cross-sectional study on juvenile foragers taken from two time points, 2005 …

Transcriptional Silencing And Anti-Silencing Of Virulence Genes In The Bacterial Pathogen Shigella Flexneri: Virb, Dna Supercoiling, And The Histone-Like Nucleoid Structuring Protein, Michael Adam Picker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Transcriptional silencing and anti-silencing affect many aspects of bacterial physiology, including virulence in bacterial pathogens. In Shigella species, a group of gram-negative pathogens that cause bacillary dysentery in humans, the histone-like nucleoid structuring protein (H-NS) transcriptionally silences virulence genes found on the large virulence plasmid while VirB anti-silences these genes. However, the mechanistic details of their interplay are not fully understood. To elucidate their regulatory mechanisms, I use the icsP virulence locus, which shares a long intergenic region with the divergently transcribed ospZ gene (1535 bp from TSS to TSS). Prior to this work, two discrete H-NS binding regions had …

Cohousing Design Strategies For Active Aging, Marisela Thompson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective:

Evaluate and identify approaches to the physical design, with emphasis on the interior design, of a cohousing model can be adapted to support the physical, cognitive and social health aspects of active aging.

Background:

Housing models evolve with the needs of society. Today, the societal practice of living in traditional nuclear-family based housing is challenged by the lack of financial resources(Blanchard 2017) and the need to care for an aging population. This project attempts to identify a housing model that promotes multigenerational co-housing as a means to ensure the health, safety, and welfare of the elder population.

One factor …

Does Distance Climbed In A 30-S Maximal Effort Test On A Simulated Climbing Machine Correlate With Wingate Variables?, Kayla Wright

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: The Wingate Anaerobic Test (WAnT) is used to assess anaerobic capacity by measuring total work. In addition to total work, the WAnT measures peak power, mean power, relative peak power, and fatigue. There are lower-, upper-, and full-body alternatives to the WAnT that can be used to measure anaerobic capacity, but there is little data on these alternatives. It may be beneficial to have a full-body assessment of anaerobic capacity, as many sporting events have full-body anaerobic demands. Simulated climbing machines are becoming popular modes of exercise. They have been compared to treadmill running and cycling in terms of …

Institutional Dissonance And Reserved Cooperation: Theory And Evidence From International Environmental Agreements, Erika Komura Masaki

UNLV Theses, Dissertations, Professional Papers, and Capstones

As global environmental problems have received more attention in the international arena, questions of global environmental governance have become more salient. The increase of international and multilateral environmental agreements has raised questions about participation, compliance, and ultimately, effectiveness of these institutions. Consequently, this dissertation seeks to understand what factors affect participation in and compliance with international environmental agreements. Specifically, I find that treaty design plays a critical role in levels of participation. Using both qualitative and quantitative analysis, I also examine the case of the Convention on International Trade in Endangered Species (CITES) as a case study, and find that …

Rapid Methods For Actinide And Strontium-89,90 Determination In Urban Matrices, Sherrod Maxwell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rapid radiochemical methods are needed to provide fast, reliable analytical measurements on a variety of different sample matrices in the case of a radiological event to protect the public, mitigate dose and protect the environment. If a radiological dispersive device (RDD), an Improvised Nuclear Device (IND) or a nuclear accident occurs, there will be an urgent need for quick analyses of urban matrices materials to support decision-making, dose mitigation and environmental clean-up. Since an incident involving a RDD or IND will likely occur in an urban or metropolitan area, it is very important to employ swift, robust analytical methods that …

Linear And Nonlinear Adaptive Attitude Control Of Asteroid-Orbiting Spacecraft Using State Feedback And Output Feedback, Nicholas Moya

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis presents the derivation of both a linear and nonlinear adaptive control law for the attitude states of a spacecraft in orbit around rotating asteroids. The asteroid is assumed to be irregularly shaped and in an elliptical orbit around the sun. The linearized, time-varying spacecraft model will assume to include unknown parameters and will have external disturbances present. The objective is to control the roll, pitch, and yaw angle trajectories of the spacecraft such that they track desired reference trajectories. To achieve this, the control law will be composed of (1) a feedback controller, sufficiently robust to disturbance such …

3-D Upper Airway Comparison Between Class I And Class Ii Adults With Excessive Daytime Sleepiness, Nga Nguyen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: The aim of the study is to determine whether there is a relationship between the risk for daytime sleepiness in adults with Class I and Class II malocclusion and the airway volume, minimum cross-sectional area, and shape at the minimum cross sectional area.

Introduction: Sleep disordered breathing (SDB) is a category of conditions defined by airway complications while a person is sleeping. Obstructive sleep apnea (OSA) is the most common of these disorders and is defined as the presence of repeated episodes of complete or partial airway obstruction, which may be associated with loud snoring and daytime sleepiness. Daytime …

Effect Of Exercise And Hypoxia On Plasma Telomerase, Charli D. Aguilar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Telomerase reverse transcriptase (TERT) is the enzyme that adds telomeric sequences to the end of linear chromosomes. Exercise has shown to upregulate acutely leukocyte TERT after just 30 minutes of running on a treadmill at 80% of VO2max (Denham et al., 2016). Hypoxia inducible factor 1 (HIF-1) is also a mediator of TERT in in vitro (Nishi et al., 2004). Moderate acute exposure to hypoxia was associated with substantial increases in plasma TERT in a recent study on rats (Wang et al., 2014). The specific aim of the current study was to identify if acute hypoxia upregulates plasma TERT …

Utilizing Teacher Response To Help Students Meet And Transfer First-Year Composition Course Objectives, Clyde Aidoo

UNLV Theses, Dissertations, Professional Papers, and Capstones

For decades, considerable scholarship has explored how teachers can respond more effectively to student writing. There has also been significant research on how first-year-composition concepts can be transferred by students to other arenas of discourse outside of this required course. This thesis begins with a brief discussion on the meaning of transfer. Then, with the Council of Writing Program Administrators’ Outcomes (knowledge of conventions, rhetorical knowledge, critical thinking, processes) as a starting point, I redefine and pare down the seven response modes described by Elaine O. Lees to five types of response (calling for correction, reminding, explaining, suggesting, and assigning) …

Examining The Influence Of Executive Resources And Mathematical Abilities On Framing Biases, Gabriel Allred

UNLV Theses, Dissertations, Professional Papers, and Capstones

The finding that the presentation of a choice (i.e., either as a loss or a gain) can affect and bias our willingness to engage in risk is one of the paramount findings of behavioral economics. First discussed by Tversky and Kahneman (1981), the framing effect demonstrates that when given two choices framed as a loss, we tend to become risk seeking. However, when the exact same outcome is presented as a gain, we become risk averse, choosing the more conservative option, regardless of the actual expected value. The effect is not limited to general research samples but has been demonstrated …

& One Night The World Will Have Changed, Hanna Andrews

UNLV Theses, Dissertations, Professional Papers, and Capstones

& One Night the World Will Have Changed is a collection of poems largely concerned with thresholds—what does one have to reconcile when standing at a precipice, when grappling with a crisis of faith, and how does one begin again? The collection is marked by three distinct sections: the first section of poems considers the effects of a devastating storm along with the emotional upheaval of abandonment (both the act of having been left, and then later, of leaving behind one life for a different one.) The second section is a series of prose poems that narrate the aftermath in …

Static And Dynamic Quantitative Microbial Risk Assessment Of Potable Reuse Paradigms, Erfaneh Amoueyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, potable reuse applications have become more common due to population growth and increased water demand, especially in communities with limited or variable water resources. However, there are concerns about potential exposure to pathogens and chemical compounds in treated wastewater. Therefore, advanced wastewater treatment processes are of paramount importance in any potable reuse system. The overall aim of this study was to develop and implement static and dynamic QMRAs to compare public health risk in various potable reuse scenarios. Cryptosporidium, norovirus, adenovirus, and Salmonella were chosen as the target pathogens. The research evaluated the performance of full advanced …

Before And After Her Body, Shannon Austin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis, titled Before and After Her Body, is a full-length poetry manuscript submitted for completion of the Master of Fine Arts – Creative Writing Program. This collection delves into several interconnected themes, including gender, the female body, myth, legacy, and time. Broken into three main sections, these poems build from an examination of women as physical bodies to an exploration of women in conversation with other women and with themselves.

In these poems, characters from myth and popular culture blend with the persona of the narrator, who is at once an observer and a participant, discovering her own tradition …

Implementing Dietary And Physical Activity Guidelines In A College Health Center, Terry Lynn Bartmus

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obesity has been classified as a major national health care problem that results in a significant increase in morbidity, mortality, and health care related costs. Seventy percent of all adults age 18 and older have a body mass index (BMI) of 25 or greater, indicating they are overweight or obese. Thirty-six percent of college students are overweight or obese. Research has shown that lack of time has further decreased weight-related counseling by primary-care providers. Printed materials have been shown to be effective in cueing individuals to engage in healthy behaviors such as following physical activity and recommended nutritional guidelines. Currently, …

Contesting And Constructing Gender, Sexuality, And Identity In Women's Roller Derby, Suzanne Becker

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this dissertation project I use the case of women’s roller derby to examine gender resistance in spaces produced and dominated by women. I examine the challenges and strategies roller derby participants deploy in resistance to the gender binary and its gender mandates, and whether or not these strategies and cultural expressions are oppositional or political. Through a combination of ethnography, participant-observation, semi-structured interviews, and analysis of web and print media on roller derby, I explain how women’s roller derby participants construct identity, varying types of femininities, and engage in forms of cultural resistance through their sport. I analyze the …

Holocene Climate Evolution Of Continental Western Eurasia Constrained By Stable-Isotope And Cation Geochemistry Of U-Th-Dated Speleothems And Meteogenic Travertine, Jonathan Lloyd Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reliable reconstructions of global and regional climate during the Holocene (11,700 years ago to present) are vital to constraining the natural range of climate variability and testing state-of-the-art models, which seek to forecast the near- and long-term impact of anthropogenic greenhouse forcing. Much of continental Eurasia is still underrepresented, however, in geological proxy reconstructions of Holocene climate variability, and the vast majority of paleoclimate data only reflect conditions during peak summer months (JJA) or the growing season. The paucity of winter proxy data has therefore been cited as a possible explanation for the current mismatch between geological proxy-based and climate-model …

Bi-Directional Testing For Change Point Detection In Poisson Processes, Moinak Bhaduri

UNLV Theses, Dissertations, Professional Papers, and Capstones

Point processes often serve as a natural language to chronicle an event's temporal evolution, and significant changes in the flow, synonymous with non-stationarity, are usually triggered by assignable and frequently preventable causes, often heralding devastating ramifications. Examples include amplified restlessness of a volcano, increased frequencies of airplane crashes, hurricanes, mining mishaps, among others. Guessing these time points of changes, therefore, merits utmost care. Switching the way time traditionally propagates, we posit a new genre of bidirectional tests which, despite a frugal construct, prove to be exceedingly efficient in culling out non-stationarity under a wide spectrum of environments. A journey surveying …
