Force Multiplier Calculations For X-Ray Binaries And Active Galactic Nuclei, Randall Cody Dannen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Motivated by the work done to explore the winds from hot stars (Lamers & Cassinelli 1999), we develop a method for self consistently calculating force multipliers for Type 1 and Type 2 active galactic nuclei (AGN), soft and hard start X-ray binaries (XRBs) spectral energy distributions (SEDs). We find that the ampflication to the radiation force can be as large as 100 even when the gas is highly ionized due to Fe and O ions. We discuss future efforts to incorporate these findings in magnetohydrodynamic simulations.

Examination Of A Screening Tool For Athletes’ Mental Health And Its Direct Implications To Sport Training And Competition, Jesse Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Sport Interference Checklist (SIC) is a psychometrically validated instrument designed to assess how often cognitive and behavioral factors interfere with athletes performance during training and/or competition as well as the extent to which athletes are interested in pursuing sport psychology to address these problems. The success of this scale inspired an interest in developing new items that assess the influence of specific mental health concerns on sport performance using the SIC format. The Sport Interference Checklist’s Sport Specific Screen for Mental Health (SIC-SSSMH) was empirically developed using 259 athletes to assist in the identification of mental health problems explicitly …

Application Of Machine Learning In Cancer Research, Mandana Bozorgi

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation revisits the problem of five-year survivability predictions for breast cancer using machine learning tools. This work is distinguishable from the past experiments based on the size of the training data, the unbalanced distribution of data in minority and majority classes, and modified data cleaning procedures. These experiments are also based on the principles of TIDY data and reproducible research. In order to fine-tune the predictions, a set of experiments were run using naive Bayes, decision trees, and logistic regression.

Of particular interest were strategies to improve the recall level for the minority class, as the cost of misclassification …

Having Or Serving: Perceptions Of Hsis, Rebecca Gates

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite substantial growth within the Latinx population and its access to higher education, there are still significant gaps with regard to degree attainment. In 2015, 36% of U.S. adults aged 25 and older had at least a bachelor’s degree. However, only 15% of those adults were Latinx, the lowest percentage amongst any racial/ethnic minority (NCES, 2016). While 67% of non-Hispanic White students entering four-year colleges complete their degree in six years, only 47% of Latinxs do so (Carey, 2009). These gaps represent an attainment disparity within higher education based upon population demographics. The purpose of this study was to address …

Handgrip Fatigue And Forearm Girth In Intermediate Sport Rock Climbers, Grace Antoinette Macdonald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Rock climbing has been increasing in popularity both recreationally and competitively. Indoor sport rock climbing is a type of climbing where the climber ascends a wall using artificial rocks (hand and foot holds) and is attached to a safety rope. Despite this increase in popularity of the sport, the physiological responses to sport climbing as an exercise to specific muscle groups are not well defined in literature. Purpose: The purpose of this study was to quantify the change in handgrip strength over a 30-minute bout of continuous climbing, specifically in intermediate sport climbers. An additional aim of this study …

Fighting For Fellowship: An Ethnographic Exploration Of Mixed Martial Arts Culture In Las Vegas, Brian O'Hara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Due to the legalization of social taboos including prostitution, gambling, and marijuana, many historical portrayals of Las Vegas have been unfavorable. Furthermore, powerful mediated imagery complete with vivid pictures of encouraged hedonism and celebrated debauchery has added to negative perceptions of this city. Despite negative sentiments, city officials are often unapologetic, and even publicly boastful about the absence of traditional values and communal appeal. However, I argue that many depictions of this city do not tell the full story of what is going on here. I looked beyond surface-level imagery and representations of Las Vegas, to discover a strong sense …

Dissolution Rates Of Allophane, Fe-Allophane, And Hisingerite And Implications For Aqueous Alteration On Mars And In Potential Returned Martian Samples, S. J. Ralston

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent measurements from Mars document X-ray amorphous/nano-crystalline materials in multiple locations across the planet. However, despite their prevalence, little is known about these materials or what their presence implies for the history of Mars. The amorphous component of the martian soil in Gale Crater has an X-ray diffraction pattern that can be partially fit with allophane (approximately Al2O3•(SiO2)1.3-2•(H2O)2.5-3), as well as low-temperature water release consistent with allophane. The chemical data from Gale Crater suggest that other silicate phases similar to allophane, such as Fe-substituted allophane (here, approximately (Fe2O3)0.01(Al2O3)0.99(SiO2)2•3H2O) and hisingerite (approximately Fe3+2Si2O5(OH)4•(H2O)), may also be present. In order to investigate …

The Structure Of Psychopathology And Its Relationship To Personality And Eeg, Vincent Rozalski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The factor structure of psychopathology has been debated in the literature, with studies showing support for several models, including one-, two-, and three-factor solutions. The factor structures often vary as a function of what symptoms and diagnoses are included, and when a wide array of diagnoses are present, a three-factor solution is often found. Personality has been shown to be related to psychopathology and its higher order structures, but there is little research regarding neurobiological associations that take into account the factor structure of psychopathology along with personality. This dissertation examined the factor structure of a wide range of psychopathology, …

Efficacy Of Combined 5-Fluorouracil And Photodynamic Therapy In Glioma Spheroids, Karanjit Singh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Standard treatment regimens consisting of surgery, radiation and chemotherapy have proven ineffective for the treatment of high-grade gliomas such as glioblastoma multiforme (GBM). An effective cure requires elimination of nests of tumor cells that have migrated from the resection margin and infiltrated normal brain. A number of localized therapies, including light-based approaches such as photodynamic therapy (PDT) and photochemical internalization (PCI) are currently under investigation for the management of GBM patients.

Several studies have demonstrated a high degree of synergy between PDT and bleomycin, via the PCI mechanism, in a variety of in vitro and in vivo models, including glioma …

Shakespeare's Hamlet As A Pilgrimage Of The Soul, Joyce Ahn

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study proposes a reading of Shakespeare’s Hamlet as a pilgrimage of the soul. There has been a consistent strain in Shakespeare scholarship which seeks to understand Hamlet and its peculiarly universal appeal in terms of its evocation of the human condition. Some examples of such commentary: Hamlet abounds in the disease imagery and is suffused with a mysterious sense of doom; it is the only play in Shakespeare with an explicit reference to Christmas; it evokes the medieval cycle plays which enacted the entire salvation history from the Creation of the world to the Last Judgment; and the play …

Mitigating Accumulation Of Aeolian Dust Particles On Solar Power Generator Panels Without Water, Sanjana Das

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accumulation of dust on solar panels poses a serious problem as it can significantly reduce light absorption and electrical energy output. Several factors affect the dust accumulation such as location, dust properties, wind velocity, system orientation, ambient temperature, humidity, and panel surface properties. Experimental and theoretical studies show that short circuit current and maximum power output of photovoltaic panels reduce approximately linearly with dust concentration. Incidentally, the locations with higher solar energy concentrations are also arid or semi-arid regions with higher dust concentrations. In order to avoid loss in power output, most PV installations perform periodic panel cleaning with water. …

Designing National Indoor Radon Surveys According To Iaea Guidance, Charles Fitzpatrick

UNLV Theses, Dissertations, Professional Papers, and Capstones

Radon is a radioactive gas that can accumulate indoors, typically in buildings with unfinished basements, poor ventilation, and/or cracks in walls or floors that lead to underlying soil, from which radon emanates. Radon is estimated to be the second most prevalent cause of lung cancer worldwide and is a threat to public health, which is a concern for national health authorities in many countries. Fortunately, radon can be measured and controlled. In order to know if radon poses a threat on a national level, studies must be performed that allow these authorities to extrapolate data from a relatively small amount …

Learning Communities And Early Student Success, Beth Gersten

UNLV Theses, Dissertations, Professional Papers, and Capstones

The first year of college is a time of significant transition in a student’s life. It is also the time that provides an important foundation for subsequent years. Learning communities (LCs) consist of a group of students taking two or more classes together. The classes should have some level of curricular integration as well as social interactions that support the learning environment. LCs offer opportunities for students to participate in rich educational environments and create connections to peers and faculty that may make a difference in whether students are successful in their first year of college and whether they persist …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study examined the effectiveness of a Mild Traumatic Brain Injury (mTBI) coaching (i.e., providing information about mTBI symptoms) and motivational incentive (i.e., a $50 gift card lottery) on the Automated Neuropsychological Assessment Metrics (ANAM) test performance. The sample included a total of 162 undergraduate and graduate students enrolled in an introductory educational psychology course. Participants were randomly assigned to one of six conditions: coached plus warning instruction and motivation incentive, coached instruction and motivation incentive, uncoached instruction and motivation incentive, coached plus warning instruction and no motivation incentive, coached instruction and no motivation incentive, and uncoached instruction and …

Testing An Improved Method For Estimating The Unsaturated Hydraulic Conductivity Of Moderately Dry Soils, Sara Gedo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prediction of water movement in the vadose zone requires knowledge of either the unsaturated hydraulic conductivity, K(θ), or the hydraulic diffusivity, D(θ), of the soil as a function of the moisture content. However, both K(θ) and D(θ) are difficult to obtain for moderately dry soils because the tests are time consuming and expensive. In order to address this issue, Globus and Gee (1995) developed a “heat pipe” method that allowed for the direct estimation of D(θ) and K(θ) for moderately dry soils on relatively short time scales. They proposed that exposing a sealed horizontal soil column to a steady thermal …

A Cross-Cultural Investigation Of The Relationship Between Customer Demographics And Hotel Room Price Perception, Jinhua Hong

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this paper, the researcher explored the significant effect of multiple demographics, age, gender, marital status, and culture, on a customer’s perception of hotel room prices. The customer’s perception of hotel room rates was assessed by three variations, perceived value, perceived fairness, and willingness to pay. Descriptive statistics, MANOVA, and ANOVA were applied in this study. The results demonstrated that age, gender, and marital status had a significant impact on a customer’s perceived value; age, gender, and culture significantly influenced a customer’s perception of fairness; yet, none of these demographics had a significant impact on a customer’s willingness to pay. …

Expression Of Line-1 In Human Somatic Tissues And The Factors Correlated With Line- 1 Expression, G. M. Jonaid

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite the long-held assumption that transposons are normally only expressed in the germline, recently we discovered that full length or partial transcripts of LINE1 are frequently found in the somatic cells. However, the extent of variation in LINE1 levels across different tissues and different individuals, and the genes and pathways that are co-expressed with LINE1 are unknown. Co-expressed genes may be candidate genes that are functioning in transposon silencing. Here, we report the extent of variation in L1HS expression levels across cancer tissues and healthy tissues collected for The Cancer Genome Atlas (TCGA). L1HS is overexpressed in most of the …

An Examination Of Student-Athlete Stress And Risky Alcohol Use, Travis Albert Loughran

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student-athletes are a sub-population of college students that are likely to engage in binge drinking behavior and experience the negative consequences associated with alcohol use (Barry, Howell, Riplinger, & Piazza-Gardner, 2015; Nelson & Wechsler, 2001). In addition, participating in intercollegiate athletics comes with unique stressors not faced by non-athlete students, such as balancing academic responsibilities with athletic obligations, managing the strain associated with playing competitive sport, and navigating complex interpersonal relationships with coaches, teammates, and peers (Parham, 1993; Watson, 2002). However, there appears to be little research examining the relationship between alcohol risk and the specific stressors associated with being …

Promoting Vocabulary Knoweldge In Inclusive Science Classrooms: Comparison Of Instructional Methods, Matthew Love

UNLV Theses, Dissertations, Professional Papers, and Capstones

A sustained trend in the overall enrollment in the United States has seen classrooms reflect more student diversity. This diversity has included increased rates of participation in general education classrooms from both students from culturally and linguistically diverse backgrounds and students with disabilities. While the increase in student diversity in general education classrooms is certainly a positive step in increasing inclusive education, shifting student demographics have presented teachers with new and evolving instructional challenges. The diverse academic, cultural, and linguistic backgrounds students represent also come to characterize the unique learning needs teachers should address. This is particularly true in science, …

Crystallographic Exploration Of Fundamental Technetium Species At Nonambient Conditions, Daniel S. Mast

UNLV Theses, Dissertations, Professional Papers, and Capstones

The study of mater under extreme conditions has yielded fascinating insight into the physical and chemical nature of materials that under more modest conditions are considered mundane but have quite unusual properties when under pressure. Examples of this are the lightest of elements found in the first two rows and in the heaviest elements of the lanthanide and actinide series. Pure elements, though the simplest possible chemical systems, have proven to be among the most complex and interesting. Technetium metal is a simple HCP transition metal that, due to its half-filled d-shell, has a rich chemistry and an important place …

An Evaluation Of Alzheimer's Disease-Related Pathology In Two Different Models Of Diabetes In Immune-Challenged Mice, Andrew Scott Murtishaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obesity, type 2 diabetes mellitus (T2DM), and metabolic syndrome are related disorders with wide-ranging and devastating effects that can be observed throughout the body. One important and understudied organ of damage is the brain. Clinical and epidemiological studies have found that T2DM, and more specifically hyperinsulinemia, significantly increases the risk of cognitive decline and increases the likelihood of Alzheimer’s disease (AD) and other forms of dementia in the elderly. Insulin has slightly different functions in the peripheral body than in the central nervous system and the dysregulation of these functions may contribute to the onset and progression of late-life neurodegenerative …

Science Identity And Underrepresented Minority Stem Organizations, Schetema Nealy

UNLV Theses, Dissertations, Professional Papers, and Capstones

President Obama indicated that there are twice as many science and technology jobs available in the U.S. as there are workers for those jobs (Office of the Secretary, 2013). To fulfill the need for more scientists and engineers, there must be increased educational support for the nation’s underrepresented minority (URM) science, technology, engineering, and mathematics (STEM) students. URM STEM organizations, such as the National Society of Black Engineers and other URM student-oriented organizations that provide academic and career resources, are widely used on college and university campuses across the nation to support these students both academically and professionally. Future developments …

Community Detection And Ranking In Big Data Graphs, Matin Pirouz Nia

UNLV Theses, Dissertations, Professional Papers, and Capstones

Community structures and relation patterns, and ranking them for social networks provide us with great knowledge about the network. A community is defined by determining a lower density of relations between groups comparing to higher density among every group. Such knowledge can be utilized for grouping similar, yet distinct, nodes with applications in health, marketing, and many more. The ever-growing variety of social networks necessitates detection of minute and scattered communities, which are important problems across different research fields including biology, social studies, physics, etc. As a result, analyzing complex networks has become very popular among researchers in academia and …
