Reframing Addiction As A Coping Response: A Needed Shift In Modern Public Health Paradigms, Anthony King

UNLV Theses, Dissertations, Professional Papers, and Capstones

What are the primary risk factors that compel one person towards addiction and not another? After decades of research, there is still no clear consensus. Some experts say addiction is a brain disease; others say it is a willful act, or even an outright crime. Nevertheless, the three research studies contained within this dissertation suggest an alternative, more parsimonious public-health-centered framework for viewing addictive behavioral patterns: as a biopsychosocial coping strategy for past and present stressors. In Study 1, this idea was examined by evaluating how symptoms of posttraumatic stress disorder (PTSD) were associated with problem gambling severity, different gambling …

Self-Perception And Positive Stereotype Endorsement, Aileen Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

The origin and reasoning behind the use of racial stereotypes has been a point of interest for researchers over the years. Many different theories have been proposed including those related to cognitive, evolutionary, and motivational explanations. However, most of these theories and the research backing them primarily focus on negative stereotyping. The origin of positive stereotyping, which also has negative implications associated with their use, has not been evaluated fully. Previous research has suggested that the motive to preserve self-worth and positive self-concept may play a role in stereotype endorsement. Two studies were conducted with the purpose of investigating whether …

Dismantling The Stigma Of "Strong Black Girl" & "Strong Black Boy:" Cultural And Gender Differences In Trauma And Suicidality Among Black Adolescents, Tiffany Mosier-Hunter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Trauma exposure has been linked to a plethora of negative outcomes, including suicidality. Despite the abundance of research on the effects of trauma, little is known about its relationship with suicidality among adolescents. Moreover, even less research examines cultural and gender specific risk factors among Black adolescents. This study was founded on the cultural model of suicide, and the gendering of suicide theory, suggesting that suicidality in minority populations is influenced by cultural experiences (i.e., traumas) and perceptions of suicide, as well as gender differences that dictate where Black adolescents fall on the suicide spectrum. Using archival data (e.g., YRBSS) …

The Operatic Innovation And Musical Language Of Rodion Shchedrin's Choral Opera Boyarina Morozova, Valeria Ore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rodion Shchedrin is an outstanding composer who uses the deep tradition of Russian musical culture in his compositions. Shchedrin’s style is very individual and consists of the universality of world perception and originality of musical language, which encompasses a sensitive assimilation of a new, careful, and respectful approach to Russian traditions. By reasonably and fragmentarily using the elements of dodecaphony, sonorics, and aleatoric music, he developed his own musical language. Thus, the purpose of this work is to explore Shchedrin’s compositional style and to discover his innovation and individual style in the opera Boyarina Morozova. Shchedrin’s compositions are unusual: …

“Everyone’S Favorite Dead Girl”: Historical Crime Fiction And Postwar Policing In James Ellroy’S The Black Dahlia, Mauricio Ortiz Zaragoza

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis argues for the importance of crime fiction as a major literary genre with global reach. Taken as a whole, crime fiction acts as a vehicle for exploring macro-level questions of social structures, political-economic processes and power relations. Within that genre, I claim that James Ellroy is a key figure who writes at the intersection of the historical novel and literary noir. As the first work in his L.A. Quartet (1987-1992), The Black Dahlia fictionalizes the investigation of the city’s most famous unsolved homicide—the gruesome murder and mutilation of Elizabeth Short. The novel, however, uses the investigation as a …

Tilt Instability Of Retrograde Disk Around One Component Of A Binary, Madeline Overton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Be/X-ray binaries are systems containing a massive Be main sequence star and a compact object companion. The Be star contains a disc of material that flows from the Be star, and may interact with the companion. In this work we consider a neutron star companion. With hydrodynamic simulations, we show that a coplanar disc around one component of a binary can be unstable to global tilting when the disc orbits in a retrograde direction relative to the binary. The disc experiences the largest inclination growth relative to the binary orbit in the outermost radii of the disc, closest to the …

Investigations Into The Relationship Between Menopause And Alzheimer’S Disease Pathology In A Mouse Model With Ovarian Follicle Depletion, Amanda M. Leisgang Osse

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer’s Disease (AD) currently affects about 6.9 million Americans, with over two-thirds of those individuals being women. Interestingly, changes in the brain indicative of AD coincide with the onset of menopause. Post-menopausal women have significantly higher levels of AD pathologies, including amyloid beta and hyperphosphorylated tau, than pre-menopausal women. To investigate the relationship between AD pathologies and menopause, we induced menopause-like state in an AD mouse model, APP/PS1, by treatment with 4-vinylcyclohexene diepoxide (VCD) to accelerate ovarian follicle depletion. To monitor the transition to menopause, vaginal lavages and cytology was performed to determine if mice reached anestrous. Both female APP/PS1 …

Increasing Swim Instructors' Perceived Knowledge Of Sensory-Based Strategies When Coaching Children Who May Have Sensory Differences, Gabrielle Palmer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although swim instructors are solely taught water safety regulations and correct swimming techniques, they are nonetheless viewed as mentors by the kids they work with. They are required to finish both their basic swim instructor (BSI) course and their cardiopulmonary resuscitation (CPR) certification, which primarily covers the fundamentals (American Red Cross Training Services, 2023; Kraft & Leblanc, 2018). However, neither provides a method of teaching swimming to children who might have sensory processing differences. This lack of education may affect both the child's participation and the swim instructor's capacity to impart knowledge. Research revealed that swim instructors are not very …
