Beyond The Numbers: A Deeper Dive Into The Dearth Of Girls And Women In Stem, Jennifer John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite decades of research attempting to better understand the dearth of girls and women in science, technology, engineering, and math (STEM), gender imbalances persist in many STEM fields. This is particularly the case in math-intensive STEM fields. The current program of research used mixed-methods research to better understand these inequities. The first paper identified gender and ethnic variation in how undergraduates reason about STEM inequities. The second paper found that how emerging adults narrate “turning points” in their relationship with math was associated with their current math outcomes and future plans to pursue math. The final paper demonstrated that how …

Measuring Gambling: Prevalence Of At Risk And Problematic Gambling In Chile 2015-2018., Juan Oyanedel Dr, Mariela Huenchumilla Ms, Andrés Rubio Mr

International Conference on Gambling & Risk Taking

This study reports the prevalence of problematic gambling in Santiago de Chile for the period 2015-2018. Two household-based surveys were implemented in the metropolitan area of Santiago de Chile in 2015 and 2018 in order to assess changes on the prevalence, characteristics and severity of gambling (n=1030 each; SE=2,2% for a CI=95%). Severity of gambling was measured using the NODS scale.

Results show that during the analysed period the percentage of at-risk players has increased, passing from 14,3% to 16,1%, among them, we identified a decrease in the prevalence of pathological gamblers, passing from 2,4% to 1,4%. We also identify …

Gambling-Related Harm And The Prevention Paradox, Matthew Browne

International Conference on Gambling & Risk Taking

Abstract (163 words)

The prevention paradox (PP) describes a situation in which a greater number of adverse events arise from lower-risk population categories, because they are more prevalent than higher-risk groups. There has been limited and conflicting evidence as to whether the PP applies to gambling-related harm.

We assessed the prevalence of 72 harmful consequences from gambling across four risk problem gambling risk categories. Respondents who had gambled on non-lottery forms in the past 6 months completed an online survey (N = 1,524, 49.4% male). The data were weighted to the known prevalence of these risk categories.

The prevalence of …

The Effects Of Sex Role Stereotype Endorsement And Work-Family Conflict On Emerging Adult Aspirations, Andrea Fink-Armold

UNLV Theses, Dissertations, Professional Papers, and Capstones

Workplace and household inequality remain prevalent in the United States and sex role (e.g. breadwinner and caregiver) stereotypes affect the roles that individuals seek out. This research used a mixed-methods approach to investigate the effects of sex role stereotypes and expected work-family conflict on the work and family aspirations of emerging adults. A racially diverse sample wrote freely about their future selves for ten minutes then completed measures to evaluate their sex-role stereotype endorsement, expected work-family conflict, and personal preferences for career and family roles. Results indicate that endorsement of stereotypes predicts increased expectations of work-family conflict, for both men …

The Construct And Predictive Validity Of Psychosocial Correlates Of Television Viewing, Raheem Paxton, Pascal Jean-Pierre, Saehwan Park, Yong Gao Dr., Stephen Herrmann, G J. Norman

Journal of Health Disparities Research and Practice

Background: Many studies have examined the consequences of prolonged television viewing, but few studies have examined the psychological states that contribute to this behavior. In this study, we evaluated the construct and predictive validity of psychosocial correlates of television viewing in a population of African American (AA) breast cancer survivors (BCS).

Methods: AA BCS (N = 342, Mean age = 54 years) completed measures of decisional balance, self-efficacy, family support, and time spent watching television online. Exploratory structural equation modeling (ESEM) was used to examine the construct and predictive validity as well as the differential item functioning of the instruments …

The Role Of Metrical Structure In Tonal Knowledge Acquisition, Matthew Rosenthal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Experienced listeners possess a working knowledge of pitch structure in Western music, such as scale, key, harmony, and tonality, which develops gradually throughout childhood. It is commonly assumed that tonal representations are acquired through exposure to the statistics of music, but few studies have investigated potential learning mechanisms directly. In Western tonal music, tonally stable pitches not only have a higher overall frequency of occurrence, but they may occur more frequently at strong than weak metrical positions, providing two potential avenues for tonal learning. Two experiments employed an artificial grammar learning paradigm to examine tonal learning mechanisms. During a familiarization …

The Hormonal Correlates Of Stress And Posttraumatic Stress Disorder Symptoms In Female Veterans, Meghan Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the increase of female veterans serving in the military, a better understanding of posttraumatic stress disorder is needed to provide comprehensive treatment. This study examines salivary cortisol in female veterans with PTSD, female veterans without PTSD, civilian females with PTSD and healthy controls. The Posttraumatic Stress and Beck Depression Inventory-II were used to assess posttraumatic stress and depressive symptoms. Saliva samples were collected at bedtime and awakening, as well as in response to the Trier Social Stress Test. Significant results were not found for diurnal cortisol levels [ F (3, 11)= .979, p < .05] or stress cortisol levels (F (3,12) = 1.140, p >.05). …

Exploring Erotic Plasticity As An Individual Difference Variable: Theory And Measurement, Lorraine Benuto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Baumeister's theory of female erotic plasticity is supported by a significant body of data suggesting that female sexuality is more malleable and more greatly influenced by cultural and contextual factors than male sexuality. Sex differences notwithstanding, it is reasonable to theorize that erotic plasticity might also vary across individuals. Based on a thematic/conceptual organization of relevant current literature, we explored erotic plasticity as optimally encompassed by six dimensions: (1) changes in sexual attitudes over time, (2) changes in sexual behaviors over time and across context, (3) fluidity of sexual behaviors along a same-sex/opposite-sex continuum (evidence of attraction and/or sexual involvement …

Examining Compressed Speech Listening Measure With College Students Who Are Visually Impaired Or Blind, William J. Marks

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychological assessments are a way of gaining some understanding of an individual in order to help make informed decisions (Sattler, 2001). These assessments offer potentially important and valuable information that can assist individuals with impaired vision in learning additional skills, improving deficient abilities, and in providing diagnostic information for future research. In addition, psychological assessments are frequently used to diagnosis a variety of psychological and learning disorders. Assessing individuals with impaired vision presents a variety of challenges from those encountered with the general population.

The current study provided an investigation into the relationship of the results of the compressed speech …
