Emotional And Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Alyson Kay Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effect of sex on how people react, emotionally and behaviorally, to different types of partner infidelity. We expected to replicate previous findings that men experience more jealousy in reaction to their partner's sexual infidelity, and women experience more jealousy in reaction to their partners' emotional infidelity. We hypothesized that sex will affect behavioral reactions to infidelity as well. Specifically, we expected men to respond to sexual infidelity by terminating the relationship and to emotional infidelity by employing mate-guarding behaviors to prevent further infidelity. We hypothesized women would display the opposite pattern, leaving a relationship in …

An Online Algorithm For The 2-Server Problem On The Line With Improved Competitiveness, Lucas Adam Bang

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we present a randomized online algorithm for the 2-server problem on the line, named R-LINE (for Randomized Line). This algorithm achieves the lowest competitive ratio of any known randomized algorithm for the 2-server problem on the line.

The competitiveness of R-LINE is less than 1.901. This result provides a significant improvement over the previous known competitiveness of 155/78 (approximately 1.987), by Bartal, Chrobak, and Larmore, which was the first randomized algorithm for the 2-server problem one the line with competitiveness less than 2. Taking inspiration from this algorithm,we improve this result by utilizing ideas from T-theory, game …

Kinematic Analysis Of Axial Rotations And The Effects Of Stress Selection On Takeoff Flight Performance, Michael L. Brewer

UNLV Theses, Dissertations, Professional Papers, and Capstones

The importance of flying insects cannot be understated; without them as pollinators, the great diversity of flowing plants could not have occurred. Flight requires a suite of highly derived morphological and physiological characteristics that may limit the evolutionary responses of other life history traits.

To investigate the complexities of maneuvering flight, I used high-speed videography to analyze wing and body motions in the HoverflySyritta pipiens(Order: Diptera) during horizontal turns called saccades. I characterized the saccades by calculating the instantaneous rotational velocities throughout the saccade, maximum rotational velocity, and the mean rotational velocity. I then compared the shape of the rotational …

Pyramid Of The Sun, James Joseph Brown

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pyramid of the Sun is a novel which is experimental in structure. It weaves traditional prose with original poems based on Aztec creation myths. The narrative is not strictly linear, but approaches the plot from several angles - past, present, and future - simultaneously. It comes back to its starting point at the end, like a snake devouring its own tail. The novel takes the Aztec and Mayan belief that time is circular and never-ending and reinterprets it in a contemporary, hard-edged setting that touches down at various points across the globe, including Moscow, Seville, Seoul and Las Vegas. Pyramid …

Claiming Citizenship: Las Vegas' Conventional Women's Organizations Establishing Citizenship Through Civic Engagement, Cynthia Cicero

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many historians of American women portray women's organized civic engagement and work to attain social, economic, and legal equality as feminism. American feminism has been expanded and applied in scholarship. The American feminists of the 1960s wanted to alter the male power structure and redefine conventional notions of womanhood. However, many middle-class women who participated in community and civic organizations valued their roles as wives, mothers, and homemakers, expressing their citizenship and community work as an extension of these roles. Their motivation in pursuing equality was to gain full citizenship status.

In this thesis, I argue that viewing women's civic …

Simulation And Analysis Of Insider Attacks, Christopher Blake Clark

UNLV Theses, Dissertations, Professional Papers, and Capstones

An insider is an individual (usually an employee, contractor, or business partner) that has been trusted with access to an organization's systems and sensitive data for legitimate purposes. A malicious insider abuses this access in a way that negatively impacts the company, such as exposing, modifying, or defacing software and data.

Many algorithms, strategies, and analyses have been developed with the intent of detecting and/or preventing insider attacks. In an academic setting, these tools and approaches show great promise. To be sure of their effectiveness, however, these analyses need to be tested. While real data is available on insider attacks …

The categories are those traveling for life-saving surgeries, for treatments to improve quality of life, for elective …

What Can Biochemistry Students Learn About Protein Translation? Using Variation Theory To Explore The Space Of Learning Created By Some Common External Representations, Thomas J. Bussey

UNLV Theses, Dissertations, Professional Papers, and Capstones

Biochemistry education relies heavily on students' ability to visualize abstract cellular and molecular processes, mechanisms, and components. As such, biochemistry educators often turn to external representations to provide tangible, working models from which students' internal representations (mental models) can be constructed, evaluated, and revised. However, prior research has shown that, while potentially beneficial, external representations can also lead to alternative student conceptions.

Considering the breadth of biochemical phenomena, protein translation has been identified as an essential biochemical process and can subsequently be considered a fundamental concept for biochemistry students to learn. External representations of translation range from static diagrams to …

The auto-centric design of Las Vegas Metropolitan area (LVMA) is unique in ways that may influence walkability. The purpose of this study was to determine which urban design characteristics are associated with walking and physical activity in moderate income neighborhoods in LVMA. Methods: The standard walkability measure developed by Frank et al. (2010) was used to calculate the walkability index of seven neighborhoods. Residents of the two most walkable and two least …

The Impacts Of Colonial And Environmental Processes On Ceramic Plainware At Salinas Province, New Mexico, Lindsey Elizabeth Daub

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis investigates whether Spanish demands on native time, labor and diet resulted in changes to the plainware ceramics used by the Salinas Pueblo Indians of New Mexico from the early 1600s to the 1670s. Increased pressures on native women's time may have resulted in a decline in the quality of the ceramic pastes, an increase in the presence of mend holes, changes in household size and composition that may have resulted in changes in the sizes of cooking vessels, and a decrease in food availability that may have resulted in decreased sizes or quantities of storage jars. While the …

Resilience And Trauma In Maltreated Youth, Timothy Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research into resilience represents a theoretical shift from the medical model in contemporary psychology to a focus on adaptation (Poulou, 2007). The relationship however between resilience and the development and PTSD in children remains unclear. The purpose of this present study is to expand on this research by investigating resilience and adaptability with respect to Posttraumatic Stress Disorder (PTSD) symptoms across maltreated youth of different ethnicities at risk for PTSD. Participants will be recruited from a Department of Family Services (DFS)-affiliated clinic in the Las Vegas area and administered the Children's PTSD Inventory (CPTSD-I), Behavior Assessment System for Children-2 Parent …

Cretaceous And Eocene U-Pb Zircon Migmatite Ages From The East Humboldt Range Metamorphic Core Complex, Nevada, Jordan Drew

UNLV Theses, Dissertations, Professional Papers, and Capstones

Zircon separates from migmatite samples from the East Humboldt Range (EHR), northern Nevada were U-Pb dated using secondary ionization mass spectrometry. Cathodoluminescence images of zircons show bright anhedral cores with abundant euhedral overgrowths surrounding them.

The overgrowths give U-Pb dates indicating two periods of zircon growth. Inner rims have a Cretaceous age population at 70.6 ± 2.6 Ma. Outer rims give Eocene ages that either fall in to a single-age population at 45 ± 1.3 Ma or are part of a range from 41-31 Ma. Discordant zircon cores have upper intercepts between 1.8 -1.0 Ga.

Cretaceous and Eocene ages are …

Who Will Tell The Story? Terrorism's Relationship With The International News Media, Katherine Eugenis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Terrorism feeds on an atmosphere of fear and uncertainty. In order for a terrorist group to achieve its purpose, its activities must be known to a mass audience. Due to the often isolated nature of the conflicts in which they are involved, terrorists groups must attract and maintain the attention of the mass media, through which they access a broader audience and gain salience. This relationship begs the question: will less media attention lead to less terrorism as groups lose their audience and are forced to use legitimate means of enacting change? This thesis analyzes the pattern of media trends …

Comparison Of The Pervasive Developmental Disorders Screening Test And Modified Checklist For Autism In Toddlers: Which Is The Better Predictor Of Autism In Toddlers?, Vanessa Marie Fessenden

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early intervention for children with autism spectrum disorders (ASD) has significant impact on children and families. Early intervention optimizes long-term diagnosis for children with ASD. Unfortunately, many children with ASD are not diagnosed until after age three and often receive services from a local school district rather than through early intervention services. However, many of the symptoms of ASD can be hard to identify because symptoms during infancy may be more difficult to detect or may present differently than manifestations of the symptoms at older ages. Despite the difficulty in identifying symptoms of ASD in young children, there are certain …

Our Side Of The Fence: Investigating The New Nativism In The United States, Candace Griffith

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines the new nativism movement in the United States. Specifically I look at groups who have formed in Arizona to combat illegal crossings over the U.S.-Mexico border. The new nativism arises from the perceived inability of the government to secure the border from illegal crossing. I draw on community policing and vigilante literatures to determine whether these groups could be considered a neighborhood watch or vigilante group. Using a sequential mixed method design, I conduct semi-structured interviews and engage in participate observation in the Sonoran desert with the Arizona Border Defenders, to identify how these groups label their …

The Second Oboe Concerto Of Sir William Herschel: A New Performance Edition, Matthew Thomas Guschl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sir William Herschel (1738-1822) is best known for his contributions to the field of astronomy. However, prior to his career in astronomy, Herschel was a professional musician. While living in Bath, England, Herschel developed an interest in astronomy. In 1781, he discovered the planet Uranus using a telescope of his own design. This was the first planetary discovery since the Classical Era. King George III was so impressed with Herschel's discovery that he offered Herschel an annual stipend with the condition that he quit his music career and move to Windsor so the royal family could have access to his …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Residential solar thermal system installations have been significantly increasing in the last decade and there exists limited resources for reasonably predicting the performance of those systems. A simulated model is developed in MATLAB® and used to predict the performance of a solar domestic water heating system. In the simulated system, hot water is generated using evacuated tube solar collectors and stored in a domestic hot water storage tank, which utilizes immersed coil heat exchangers. The system is designed to provide hydronic radiant floor heating to its occupants based on the heat loss of a building energy model for an energy-efficient …

Assessing The Conceptual Equivalence Of Measure Of Suppression In Culturally Diverse Samples, Amanda Louise Haboush

UNLV Theses, Dissertations, Professional Papers, and Capstones

In Western populations, some emotion regulation strategies have been associated with positive interpersonal abilities and mental health outcomes, while others, such as suppression, have been associated with negative physical and mental health outcomes (e.g., Eisenberg et al., 1997; Esterling, Antoni, Kumar, & Schneiderman, 1993; Gross & Muñoz, 1995; Kovacs, Joormann, & Gotlib, 2008). However, Butler, Lee, & Gross (2007) have demonstrated that the negative effects of suppression do not occur in some Eastern cultures. This inconsistency may be due to a lack of measurement equivalence across cultures.

To examine suppression in other cultural groups, researchers often adapt existing measures that …

Black Teachers, White Schools: A Qualitative Multiple Case Study On Their Experiences Of Racial Tokenism And Development Of Professional Black Identities, Abigail Kathleen Hasberry

UNLV Theses, Dissertations, Professional Papers, and Capstones

An emerging body of research shows that retention of minority independent school teachers creates a positive multicultural climate and increases the likelihood that minority families will enroll their children in the schools as well as preparing all students for a pluralistic society (Brosnan 2001b, AIMS 2010, Katz & Wishine 2001). However, retaining minority teachers in predominantly White and affluent independent schools has proved challenging (Brosnan 2001, 2001b, 2009). This qualitative multiple case study extends the current literature on Black private school teachers by not only examining the experiences, but also the coping strategies and professional identity development processes of nine …

Development And Validation Of Heat Transfer Model To Predict Indoor Air Temperatures In Roofpond Buildings, Afzal Hossain

UNLV Theses, Dissertations, Professional Papers, and Capstones

Roofponds mimic the ways in which nature tempers and controls the global climate; they utilize higher heat capacity of water to passively control the temperature of the interior space. From a thermal standpoint, roofponds are strong performers, providing high solar savings fractions, interior temperature stability, enhanced thermal comfort and very low operational power requirements. Moreover, due to convective heat transfer within the water bags, heat gains or losses are quickly distributed throughout the roofpond to create a very homogeneous distribution of heat throughout the floor area covered by the system.

An Analysis Of Co-Teaching Instruction Provided In Teacher Education And Inservice Training For Special Education And General Education Teachers, Catherine S. Howerter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The No Child Left Behind Act (NCLB) (2001) and the Individuals with Disabilities Education Improvement Act (IDEA)(2004) call for students with disabilities to be given access to the general education environment. Currently, at least half of all students with disabilities receive more than 80% of instruction in the general education classroom (U.S. Department of Education, 2008). Although there are no direct mandates to use co-teaching, it has become the preferred model of instructional delivery within the general education classroom (Pugach & Blanton, 2011).

General and special education teachers need to be provided instruction on the fundamentals of co-teaching in their …

The purpose of this study was to investigate the relationship among the quality of life of families that have at least one child with autism spectrum disorder, parental stress level, and partnerships between the family and professionals. Also, parent perceptions of parental stress, family quality of life, and family-professional partnerships were assessed to ascertain if they could be predicted from different variables (e.g., ethnicity, educational levels, income levels, and parental relationship status, etc.). The study examined the relationship among the three variables (e.g., family quality of life, parental stress, and family-professional partnership). Participants were recruited from an autism center located …

Effects Of Environmental Variables On The Reproduction Of Quagga Mussels (Dreissena Rostriformis Bugensis) In Lake Mead, Nv/Az, Richard Steven Ianniello

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2007, quagga mussels (Dreissena rostriformis bugensis) were found in Lake Mead and have spread downstream on the Colorado River and to other lakes and reservoirs in the Southwestern United States. The quagga mussel's extremely quick colonization of Lake Mead and annual veliger abundance trends provide evidence that the quagga mussels in the Southwest have different reproductive behavior than in previous habitats. This study is one of the first to specifically examine quagga mussel reproduction in the Southwest and examines how quagga mussel reproduction varies at sites known to have different temperatures and other environmental variables resulting from the input …
