Sex, Drug Courts, And Recidivism, Doria Nour Dandan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research studies have identified gender differences in the drug abusing patterns and treatment needs of men and women. Even so, studies on the drug court model have not assessed drug court effectiveness across sex. Using secondary data collected from the Ada County Drug Court, the recidivism rates of drug court participants (n=259) and probationers (n=235) were analyzed. Drug court participants were found to be less likely to recidivate compared to probationers, which supports previous research on drug court effectiveness. Regression analyses failed to find an interaction between group membership and sex, thereby indicating that the effect of the drug court …

I examined the current social educational issues that affect female ethnic minority students in France, as well as …

Partial Phonon Density Of States Of 57-Iron And 161-Dysprosium In Dyfe3 By Nuclear Resonant Inelastic X-Ray Scattering Under High Pressure, Elizabeth Anne Tanis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The dual partial phonon density of states (DOS) from two different Mossbauer isotopes (161Dy and 57Fe) in the same material (DyFe3) was successfully measured using the nuclear resonant inelastic x-ray scattering (NRIXS) technique at high pressure. Nuclear inelastic scattering measurements yield an in-depth understanding of the element-specific dynamic properties. The Debye temperatures , the Lamb-Mossbauer factor, and the vibrational contributions to the Helmholtz free energy, specific heat , entropy and internal energy are calculated directly from the phonon density of states.

Bacillus Cereus And Bacillus Anthracis Germination Kinetics: A Michaelis-Menten Approach, Helen Luu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bacillus species are rod-shaped, gram-positive bacteria that are capable of producing endospores. In this dormant stage, the endospores can persist in hostile physical and chemical environments. Once conditions become favorable, the spores germinate into actively dividing cells, vegetative cells. Germination is a crucial step for the pathogenicity of the Bacilli in affecting a host organism.

Our study applies mathematical approaches to spore germination to determine whether the binding of one germinant will affect the binding of another germinant. We pursued this approach with two different species, B. cereus and B. anthracis, both pathogenic organisms. B. cereus is a widely known …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The harmful health effects of lead exposure have been known for centuries, yet lead is still produced and utilized in a variety of ways. There have been many movements to rid the environment of this toxic metal in hope to reduce the number of individuals who are and who may potentially be exposed. Lead exposure is responsible for a myriad of negative health effects most notably lowering IQ scores in children. Extensive amounts of data have been collected from areas of the country with known lead hazards, hazards that have been identified through hundreds of thousands of elevated blood lead …

Incidental Music: Enhancing The Emotional Experience Of The Audience, Daniel Edward Nelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Environmental psychologists, like Robert Gifford who study transactions between individuals and their physical settings, maintain that as an individual's environment is changed, the environment also changes his/her behavior and experience. (Gifford, 2002) Like other segments of a theatrical setting, manipulation of the environment can enhance or constrain a broad range of audience actions from traditional theatre audiences to shoppers in a mall or guests at a wedding. Physical elements, as well as other ambient factors such as lighting, color, and quality of materials, set design, music, fragrance, and room temperature are a sample of the dramatic elements used to orchestrate …

Health Status Of Infants And Children From The Bronze Age Tomb At Tell Abraq, United Arab Emirates, Kathryn Mary Baustian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Tell Abraq is significant because it is the largest prehistoric site on the southern coast of the Arabian Gulf. It was strategically important as an ancient port, regionally surrounded by large political centers. Commingled remains were located in a small tomb (6 m) used for a 200 year period (2200-2000 BC). The site was continually occupied from the 3rd millennium BC up to the 1st century AD. In the tomb were minimally 286 adults and 127 subadults. What is extraordinary is the number of pre-term (3rd trimester) infants (n=28, 22%), neonates (n=12, 9%), and infants under 2 years (n=46, 36%). …

The Role Of Visual, Vestibular, And Somatosensory Systems In Postural Balance, Mary Grace Gaerlan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The integration of visual, vestibular, and somatosensory components are used to maintain one's postural balance. Postural control changes over time and body sway increases with age. The different sensory systems begin to develop and refine starting when children are young, while in older adults it begins to decline. Hence, it is important to study the changes that occur in postural balance. There is very little known about balance of younger adults. If balance issues are identified early in adult life it is possible to prevent exacerbation of balance decline as one ages. If nurse practitioners are aware of what dominant …

Transforming Space Into Place: Development, Rock Climbing, And Interpretation In Red Rock Canyon National Conservation Area, 1960-2010, Megan Sharp Weatherly

UNLV Theses, Dissertations, Professional Papers, and Capstones

Though Americans tend to view wilderness as separate from nature, environmental historians have argued that wilderness is a cultural construct more than a quantifiable geographic category. Red Rock Canyon National Conservation Area (NCA), a 195,000-acre tract located west of Las Vegas, Nevada, is one such cultural construction. Since 1960, this BLM-managed parcel has served as a local and regional expression of broader, national trends in outdoor recreation, interpretation, and development and thereby forced visitors to engage (often unknowingly) in a cultural dialogue about consumerism, technology, and identity. With information from newspapers, archival collections, oral histories, and government documents, this thesis …

Narrative Comprehension For Functional Survival Spatial Relations, Paul James Schroeder Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

Spatial situation models are mental representations of the relationship between characters and objects in the narrative environment. Functional spatial relationships describe an interaction (or potential interaction) between characters and objects in the narrative environment. Although functional relations tend to produce stronger representations as compared with nonfunctional ones (Radvansky & Copeland, 2000), recent data also suggest that specification of causal information, specifically, survival-based scenarios in which characters are described as in immediate danger, may contribute to the construction and maintenance of spatial situation models (Jahn, 2004). For the current study, this idea was tested by comparing reading times and comprehension for …

African American And Caucasian Males' Evaluation Of Racialized Female Facial Averages, Rhea M. Watson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The answer to what makes a face attractive has been debated for generations and studied in different disciplines. The current study investigated African American and Caucasian males' evaluation (attraction) to racialized female faces. Faces varied from 100% African American to 100% Caucasian (and included variations that were 25% of either group, or 50% of both groups). Twenty African American and 30 Caucasian men each viewed ten faces, and evaluated them in terms of their appearance and the likelihood that the men would interact with (befriend, date, or marry) the person pictured. Findings revealed that African American men found the 100% …

Re-Entry African American Male High School Dropouts Through The Lens Of Critical Race Theory With Content Analysis Of The Case Studies, Robert Paul Walker

UNLV Theses, Dissertations, Professional Papers, and Capstones

This is a multi-case study, utilizing in-depth interviews, of three African American male high school dropouts who are reentering an alternative high school program in Southern Nevada. The participants tell of their life experiences, broadly considered, in relationship to school, family, peers, and discrimination. Hearing their story in their own voices gives a forceful dimension to the statistics of the group many call the "endangered species." The in-depth interviews reveal the challenging experiences that many young African American men must rise above in order to survive, including the daily incidents of racism--both institutional and individual--that all African Americans endure. The …

Enhanced Food Marketing To Children On The Internet: A Content Analysis, Sarah A. Ochsner

UNLV Theses, Dissertations, Professional Papers, and Capstones

In light of the continuing epidemic of childhood obesity, aggressive food marketing strategies have come under increased scrutiny as a possible contributing factor. It has been acknowledged in numerous studies, that poor nutrient quality of food and beverages dominate children's programming. The growth in child-specific media envoys has further increased favorable opportunities to market food and beverages to children, notably less regulated and parentally unsupervised. According to the U.S. Census Bureau, 65% of children aged 6-11 have home access to the Internet; and today, the majority of food manufacturers operate websites appealing to children. The Institute of Medicine issued a …

This paper discusses the implementation and impact of the police order-maintenance unit during its operation.

Flow Rate Measurement In A High Temperature, Radioactive, And Corrosive Environment, Taleb Moazzeni

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accurate measurement of coolant flow rate is essential for determining the maximum power required by the nuclear plant operation and critical for monitoring its operation safety. However, no practical off-the-shelf flowmeter is available to satisfy all the pressing multidimensional operation requirements (i. e., high temperature, high irradiation, and high corrosion). This work thus deals with the development of a new flowmeter for nuclear power plant/reactor process-monitoring and real time analysis; this proposed flowmeter shall be able to continuously conduct robust measurements under extremely harsh environment with high irradiation, high pressure, high temperature and corrosive media. We investigate a transit-time based …

Phylogeography Of Two Closely Related Anurans, The Relict Leopard Frog (Rana Onca) And Lowland Leopard Frog (Rana Yavapaiensis), Viktoria Hemmings

UNLV Theses, Dissertations, Professional Papers, and Capstones

I investigate the phylogeography of the relict and lowland leopard frogs (Rana onca; R. yavapaiensis) inhabiting the Mojave and Sonoran deserts. In Chapter 1, I summarize literature describing taxonomy, phylogenetics, and the possible effects of Quaternary climate change on distribution. Examples of phylogeographic patterns from generally co-distributed organisms are provided to develop background for interpreting the structure. In Chapter 2, I investigate the phylogeography of these frogs using mitochondrial DNA data. The analysis supports a previously determined phylogenetic break between taxa however further dividing R. yavapaiensis into two lineages. I estimate a possible Early Pleistocene divergence of R. onca and …

Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu

UNLV Theses, Dissertations, Professional Papers, and Capstones

The access provided by streets and highways to adjacent lands are managed by controlling the spacings between the access points including signals, driveways, and media openings on mid-block segments, and setting the limit on the corner clearances around intersections. There have been studies on evaluating the impact of access management techniques on safety and mobility in urban areas. Samples of mid-block segments and intersections can be collected from selected arterials. Because the mid-block segments or intersections in the same arterials share the same missing information, safety and mobility on them show unique features that should be taken into account when …

Which Financing Model Is Right For Hotel Properties? An Exploratory Study Of Financing Models Highlighting The Practice And Effects Of Different Financing Models Adopted By Hotel Industries In Usa And Singapore, Keng Tiong Christopher Goh

UNLV Theses, Dissertations, Professional Papers, and Capstones

The high debt-financing model adopted by hotel owners in United States had contributed to a large number of foreclosures during the economic downturn. In contrast, the conservative financing model adopted by hotel owners in Singapore had sheltered them through the past recessions. Cultural values may have influenced the types of financing model adopted by hotel owners. Americans have a value system of using borrowed money to invest, while Singaporeans have a value system of saving for rainy days and spending within one’s means.

The studies concluded that hotel owners in the United States and Singapore should consider Juglar’s nine to …

Impacts On Maternal Diet In A Transitional Community In Rural Costa Rica: Potential Implications For The Developmental Origins Of Obesity-Related Disorders, Allison Cantor

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines maternal diet in a rural, transitional community in Costa Rica. Using cross-cultural categories recognized in the ethnographic literature (i.e. dietary taboos, dietary prescriptions, food cravings and the acknowledgment of a special post-partum period diet), maternal dietary practices were identified in the local community through surveys (n=45) and participant-observation (n=5), and to reflect the actual consumption patterns of pregnant and nursing women in the area, 24-hour diet recalls were administered to 5 pregnant or nursing women. In light of the recent changes that increased tourism has brought to the Monteverde Zone, focus groups were employed to determine impacts …

Displacement Or Diffusion: A Secondary Analysis Of The Las Vegas Safe Village Initiative, Daniel Duane Swanson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Police initiatives have been implemented by many agencies in an attempt to curtail growing crime rates. The Las Vegas Metropolitan Police Department implemented the "Safe Village Initiative" to address this issue in west Las Vegas. This deterrence based model reduced calls for service in the target area with a diffusion of benefits to the surrounding neighborhoods.

The current study will analyze two research questions pertaining to the "Safe Village Initiative". The first will assess the possibility that a displacement of crime occurred as a result of the treatment. The second research question will address whether, if no displacement occurred, there …

Attitudes Of Young Adults About Breastfeeding And The Association Of Breastfeeding Exposure, Cheryl Lynn Darby-Carlberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study was conducted to determine the attitudes of young adults in Clark County, Nevada about breastfeeding and was a replication of part of a study by Marrone, Vogeltanz-Holm, and Holm (2008). The theory for reasoned action was used as the framework to guide the study. This theory explains deliberate behavior and how specific behaviors, such as breastfeeding, are affected by individual attitudes and social support. The research is a cross-sectional correlational study and sought to test two null hypotheses: (1) There is no association between previous exposure to breastfeeding and positive attitudes toward breastfeeding, and (2) There is no …

The purpose of this study was to examine the factors that influence attitudes towards prostitution. Students from University of Nevada, Las Vegas and University of British Columbia (N=591) were compared based on their responses to the Attitudes Towards Prostitution (ATP) Scale and by demographic differences. Analysis of variance (ANOVA) identified significant differences in ethnicity, religiosity, and certain sexual experiences. Regression analysis revealed location of students and religiosity were significant predictors of attitudes.

Phyllosilicate Mineralogy, 40ar/39ar Geochronology, And Genesis Of Petrocalcic Soils In The Southwest U.S.A., Colin R. Robins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obtaining isotope ages for arid soils and paleosols, including carbonate-cemented (calcic and petrocalcic) horizons, constitutes a significant challenge for soil scientists, geomorphologists, and stratigraphers. Carbonate-cemented soils foster diverse suites of authigenic minerals with exciting potential for geochronology, however, this potential has not been realized. This dissertation describes the timing of pedogenic palygorskite and sepiolite crystallization in extremely old, extant petrocalcic soils of the southwest U.S.A., and assumes that these fibrous, high-magnesium phyllosilicates contain sufficient lattice-bound K to warrant vacuum-encapsulated 40Ar/39Ar geochronology. This three-part study evaluated the (1) selective extraction, (2) 40Ar/39Ar analysis, and (3) pedogenesis of palygorskite and sepiolite.

An Examination Of The Life And Work Of Gustav Hasford, Matthew Samuel Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

While Stanley Kubrick's film Full Metal Jacket has remained in the national consciousness twenty years after its release, the author of its source material, Gustav Hasford, has not. Few people know or remember that the Oscar-nominated film was not an original work but was adapted by Hasford, Kubrick, and Dispatches author Michael Herr from Hasford's 1979 novel The Short-Timers. Fewer people remember that following the well-reviewed The Short-Timers Hasford published a sequel, The Phantom Blooper, as well as one final novel A Gypsy Good Time, a frenetic parody of detective fiction. To say that Gustav Hasford is primarily remembered as …

Atomic Governance: Militarism, Secrecy, And Science In Post-War America, 1945-1958, Mary D. Wammack

UNLV Theses, Dissertations, Professional Papers, and Capstones

This history of America's post-World War II atomic program examines the institutional impulses that drove its evolution from 1945 through the 1958 moratorium on atmospheric weapons testing. Based on archival research and methodologies borrowed from sociologists and legal theorists, it focuses on the motivations of and decisions made by military officers, program managers and affiliates in the private sector, their relationships, and the alliances they formed with congressmen. This analysis identifies a two-stage process of self-interested decision-making through which the armed forces, seeking to mitigate postwar loss of funding and influence, gained de facto control of the atomic program that …
