To Test Or Not To Test: Barriers And Solutions To Testing African American College Students For Hiv At A Historically Black College/University, Naomi M. Hall-Byers, Jennifer Peterson, Malynnda Johnson

Journal of Health Disparities Research and Practice

Young African Americans are disproportionately affected by sexually transmitted infections, including HIV. The purpose was to identify reasons that African American college students at a historically Black college/university (HBCU) identified as barriers to HIV testing, and how these barriers can be removed. Fifty-seven heterosexual-identified undergraduate students (ages 18-25) attending an HBCU in the southeastern US participated in the study. Latent content analytic techniques were used to code the transcripts for themes and categories, and representative quotations were used in the findings. Qualitative data indicates three main themes used to avoid testing and three themes to encourage testing. Students were forthcoming …

Attributions And Coping Behaviors Communicated Among Bullied Students: An Analysis Of Bullying Blogs, Carly Marie Danielson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student bullying is a growing and damaging problem in society today. This study investigates the role of bullied students' attributions and coping strategies through Heider's (1958) attribution theory (AT) and Crick and Dodge's (1994) social information processing model (SIP). Rich data are obtained from bullying blogs that showcase how bullied individuals make sense of their experiences online. The important findings that emerge from this investigation relate to similarities in men's and women's attributions and differences in their coping strategies and resources to manage victimization. Additionally, both men and women experienced similar negative outcomes with particular coping strategies and resources, suggesting …

The Mental Organization Of People's Permanent And Situational Attributes, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis investigated whether readers would integrate physical descriptions of characters into one coherent mental representation or if they would keep mental representations separate. The integration of multiple concepts has been examined in the context of the fan effect, which is the finding that an increase in the number of learned associations for a concept can result in an increase in retrieval times and error rates (Anderson, 1974). However, there is typically not a fan effect when people are able to organize the related information into a single integrated situation model (Radvansky & Zacks, 1991). Previous studies investigating the fan …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

School Climate, Absenteeism, And Psychopathology Among Truant Youth, Marisa Charlene Hendron

UNLV Theses, Dissertations, Professional Papers, and Capstones

School refusal behavior has become highly problematic for schools worldwide. Researchers have focused efforts on examining many factors related to absenteeism, including child, parent, family, peer, school, and community variables. Many previous researchers examined absenteeism between groups (i.e. truants vs. nontruants, truants vs. school refusers). The present study investigated percentage of absenteeism in relation to contextual variables in a diverse sample of truants referred to programs designed to improve attendance. First, a model of school climate (Sharing of Resources, Order and Discipline, Parent Involvement, Student Interpersonal Relations, and Student-Teacher Relations) contributing to severity of absenteeism was tested via structural equation …

Family Environment And Severity Of Absenteeism In Youth, Rachel Marie Loftis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between family environment and severity of youth absenteeism in clinical and community settings. Previous researchers have adopted a categorical approach to investigating the role of family environment in problematic absenteeism by diving youth into discrete categories and these studies are almost exclusively conducted in clinical settings. The current study contributes to the literature by adopting a dimensional approach that examines the impact of family environment on problematic absenteeism across diagnostic and functional categories.

The first aim of the study was to determine the family environment characteristics most predictive of absenteeism severity. The first hypothesis …

What's Age Got To Do With It? Examining How The Age Of Stimulus Faces Affects Children's Implicit Racial Bias, Erica Cheree Noles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Discrepant results regarding the emergence of children's implicit racial bias suggest additional research is needed to understand the developmental timeline of racial bias. Investigations using established explicit racial bias measures and the implicit association task with children demonstrate racial bias in young children (Aboud, 1988; Baron & Banjai, 2006). These findings do not corroborate the only known developmental use of the affective priming task (APT) to measure racial bias, which suggests implicit racial bias does not emerge until adolescence (Degner & Wentura, 2010). Variations in the task demands, the types of stimuli used to represent the construct of race, and …

Sex In The Brain: The Relationship Between Event Related Potentials And Subjective Sexual Arousal, Taylor Lynn Oliver

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research investigating the relationship between subjective sexual arousal and physiological arousal has focused primarily on measures of genital arousal and has yielded only modest concordance rates between genital and subjective sexual arousal in men, and low concordance rates in women. One of the nagging confounds in the literature, however, has been the fact that different assessment methods are necessitated by men and women's differing genital physiology (i.e., vaginal photoplethysmography in women and penile plethysmography in men). This study sought to investigate the relationship between subjective sexual arousal and a different type of physical arousal (brain activation) that could be measured …

Wisc-Iv Profiles In Children With Attention Deficit Hyperactivity Disorder And Comorbid Learning Disabilities, Elyse Parke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention Deficit Hyperactivity Disorder (ADHD) and learning disabilities (LD), including Reading Disorder (RD), Disorder of Written Expression (DWE), and Developmental Coordination Disorder (DCD) all co-occur at high rates. Previous research indicates increased neurocognitive impairment in ADHD with the presence of comorbid diagnoses. However, few direct comparisons between intellectual profiles of children with one or multiple ADHD and LD diagnoses are available, specifically for the Wechsler Intelligence Scale Fourth Edition (WISC-IV), despite its frequent and historical use with this population. Profile analysis may contribute insights into spared and impaired abilities. Therefore, the present study addressed these matters by comparing WISC-IV profiles …

Cognitive Differences Between High And Low Responders Of A Tier Ii Reading Intervention, Jillian Cohen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study evaluated a population of young students with potential reading disabilities who participated in a large western school district's Reading Skills Development project from October 2012 to May 2013. The following questions were addressed: Are there cognitive differences between students who respond well to an intense Tier II reading intervention and those who make little progress? If so, which cognitive skills best discriminate between high and low responders? De-identified data was collected from 171 struggling readers in 1st through 3rd grade who participated in the Reading Skills project. After controlling for English proficiency level, high and low responders were …

The Effect Of Early Life Stress On Methamphetamine Damage In The Striatum, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Methamphetamine (METH) abuse impacts the global economy through costs associated with drug enforcement, emergency room visits, and treatment. Hyperthermia is a leading cause of METH induced emergency room visits and may lead to neural damage. Previous research has demonstrated early life stress, such as childhood abuse, increases the likelihood of developing a substance abuse disorder. However, the effects of early life stress on neuronal damage induced by chronic METH administration are unknown. We aimed to elucidate the effects of early life stress on METH induced dopamine damage in the striatum. Animals were separated three hours per day during the first …

A Model Of Hospitality Employee Engagement, Hee Jung Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on employee's state-like psychological resources by investigating individual and organizational antecedents to employee engagement and valued human resource outcomes. The purpose of this study was to develop and test a theoretical model that explains the interrelationships among six constructs and to explore the mediating effects of employee engagement. Structural Equation Modeling using AMOS (18.0) statistical software was used to test the full structural model (measurement and structural model) of the hypothesized relationships among the variables with a sample of hospitality employees. The findings supported all hypothesized relationships except the direct relationship between employee engagement and turnover intention. …

Posttraumatic Stress Disorder In Maltreated Multiracial Youth, Harpreet Kaur

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lemos-Miller and Kearney (2006) first identified depression as a meditator of (1) dissociation and posttraumatic cognitions and (2) PTSD in maltreated children. In addition, they found that African American status weakened the mediating relationship, whereas multiracial status strengthened the mediating relationship. Multiracial youth in Lemos-Miller and Kearney's study experienced a stronger relationship between depression and PTSD than other ethnic groups.

The present study evaluated the Lemos-Miller and Kearney (2006) model of PTSD among a larger sample of multiracial youth. The present study sought to identify whether the Lemos-Miller and Kearney (2006) finding regarding multiracial youth could be replicated. The presented …

The Role Of Self-Concept In Consumer Behavior, Marisa Toth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding the influences underlying consumption has become an increasingly important goal for marketers. This study examined the role of self-concept in consumer behavior, specifically product evaluation. The influences of various dimensions of the self-concept are examined in regard to four product dimensions: public luxury, public necessity, private luxury, and private necessity. Differences due to variations in individual levels of self-monitoring are also measured. Overall, results showed that the more conspicuous a product is (higher on luxury/public dimensions) the greater the relationship between evaluation and ideal self-images (ideal self and ideal social self) for both high and low self-monitors.

The Role Of Self Concept In Consumer Behavior, Marisa Toth

Graduate Research Symposium (GCUA) (2010 - 2017)

Understanding the processes that underlie consumer behavior has become an increasingly important area of research, especially for businesses and marketers. One of the most commonly studied variables believed to impact consumer behavior is self-concept.

The purpose of the current study is to examine the influence of self-concept in consumer behavior and identify factors that influence the relationship. Specifically, what is the relationship between different aspects of the self-concept and the consumption of publicly and privately consumed luxuries and necessities? Furthermore, how will this relationship be affected by the level of self-monitoring an individual displays?

The Success Of Gay–Straight Alliances In Waterloo Region, Ontario: A Confluence Of Political And Social Factors, Alex St. John, Robb Travers, Lauren Munro, Renato M. Liboro, Margaret Schneider, Carrie L. Greig

Psychology Faculty Research

This article outlines how gay–straight alliances (GSAs) work to connect youth with community resources, and outlines the political and social context of GSAs in Waterloo Region, Ontario, Canada. Fifteen individuals (youth, teachers, and a lesbian, gay, bisexual, transgender, and queer [LGBTQ] youth service provider) participated in interviews about the role of GSAs in creating supportive school environments for LGBTQ youth and their allies. Analyses of the interview data found that, apart from providing direct support to LGBTQ students, GSAs in Waterloo Region decrease isolation by connecting youth with other LGBTQ community members, events, and resources. This article discusses how the …

Community-Level Interventions For Reconciling Conflicting Religious And Sexual Domains In Identity Incongruity, Renato M. Liboro

Psychology Faculty Research

Two of the most unstable domains involved in identity formation, the religious and sexual domains, come into conflict when vulnerable populations of the lesbian, gay, bisexual and transgender community experience oppression from the indoctrination of religious beliefs that persecute their sexual orientation. This conflict, aptly termed identity incongruity in this article’s discourse, results in a schism that adversely affects these vulnerable populations. This paper investigates the roles of religion, spirituality and available institutional solutions to propose customized, culturally adapted, contextually based and collaborative community-level interventions that would facilitate the reconciliation of the conflicting identity domains.

A Computational Perspective Of Schizophrenia, Ernesto H. Bedoy, Geoff Powell, Jefferson Kinney

McNair Poster Presentations

The etiology of schizophrenia remains largely elusive, thus dampening the effectiveness of current treatment strategies. Abnormal neural migration and neurogenesis in the hippocampus have been suggested to be involved in schizophrenia (Jakob & Beckmann, 1994). A few approaches, including computational modeling, have investigated schizophrenia as a network disorder. Computational modeling uses mathematics to predict the behavior of biological systems based on the input of a set of parameters collected from laboratory experiments. In this study, we constructed a computational model to explore the ramifications of additional PV neurons migrating to an aberrant location in the hippocampus and interfering with a …

Modulatory Effects Of Gaba(B) Receptor Facilitation In A Model Of Chronic Inflammation, Michael A. Langhardt, Jefferson Kinney

McNair Poster Presentations

Inflammation within the brain (neuroinflammation) has been associated with a number of neurodegenerative diseases, including Alzheimerʼs disease (AD) (Solito et al., 2012). Within the brain, inflammation is defined broadly as prolonged activation of the brainʼs immune cells, known as glial cells. Excessive activation of glial cells within the brains of AD patients is a hallmark of the disease, however the mechanism by which this contributes to disease pathology is relatively unclear (Jo et al., 2014). Recently, studies have shown that glial cells, known as astrocytes, are able to synthesize and release the inhibitory neurotransmitter GABA (Charles et al., 2003). Further, …

Misusing Freud: Psychoanalysis And The Rise Of Homosexual Conversion Therapy, Jonathan Barrett

Psi Sigma Siren

Current ideas of conversion therapy often focus on extremist religious groups that wish to cleanse the world of what they view as an immoral abomination, homosexuality. However, conversion therapy started out as mostly scientific curiosity. Sigmund Freud’s psychoanalytic research on human sexuality helped set the standards on psychosexual study in the twentieth century. Unfortunately, his views on homosexuality became distorted in the 1950s when psychoanalysts and psychiatrists used his methods of therapy but ignored his conclusions on homosexuality and sexual nature itself. Such distortions led to the destruction of many lives within the homosexual community.

Reparative therapy on homosexuals exploded …

Quality Of Peer Relationships Among Children With Selective Mutism, Marielle Leo, Rachele Diliberto, Christopher A. Kearney

McNair Poster Presentations

The current study examined the quality of peer relationships among children with selective mutism. Previous research suggests that children who are selectively mute have difficulty making friends and have poor outcomes in treatment. Participants were derived from the UNLV Child School Refusal and Anxiety Disorders Clinic. An initial assessment was conducted by the Clinic therapist. The study utilized a demographic form, the Child Behavior Checklist, and the Anxiety Disorders Interview Schedule—Parent Version. The current study found that children who are selectively mute ranged in the quality of friendships, and this knowledge may be used to help treatment outcome.

Pre-Traumatic Factors Of Career-Related Ptsd: A Systematic Review Of The Literature, Michael G. Curtis, Russell T. Hurlburt

McNair Poster Presentations

This paper examined and synthesized the (limited) available literature on the pre-traumatic predictors of PTSD, specifically targeting populations in which traumatic events are experienced frequently because of the requirements of their positions, i.e., firefighters, police, and military personnel. A total of 21 articles were included in the final literature review and were used to assess the current available knowledge of the pre-traumatic traits of career-related PTSD, and address potential gaps in the literature. The culmination of this research was used to create specific risk profiles for each of the high risk careers included in this review, firefighters, police, and military …
