Examination Of Factors Reported By Athletes To Interfere With Their Lives Outside Of Sports, Jesse Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The original Sport Interference Checklist (SIC) is a mental-health screening instrument designed to assess the extent to which mental health factors interfere with athletes’ performance during sport training or competition. In addition, the SIC appraises whether athletes are interested in pursuing psychological treatment for the aforementioned factors. Although validated, the SIC does not assess how the aforementioned factors affect athletes’ performance outside of sports. Doing so would permit professionals to examine the influence of these factors across sport training, sport competition, and life outside of sports.

The purpose of this study was to determine the psychometric properties and clinical utility …

Transposable Element Expression In Human Embryo Single-Cell Rna-Seq Data, Corinne Sexton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Transposable elements (TEs) are genetic sequences which are mobile within the genome, including DNA transposons and retrotransposons. Though the vast majority are no longer able to move or duplicate in humans, they still are actively transcribed in both germline and somatic cells, particularly in early human development. TEs are expressed in an extremely cell-type and stage specific pattern during embryogenesis, suggesting that they may either have a regulatory role in the cell or be transcribed along with cell-specific genes. However, earlier studies have focused on hESC models or early embryos up to day 6, with differing patterns of TE expression. …

Menstrual Cycle Changes In Dysregulated Eating Symptoms, Kimberly S. Stevens

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Animal and human data indicate that fluctuations in ovarian hormones (e.g., estrogen and progesterone) across the estrus/menstrual cycle drive changes in eating behavior. Post-ovulatory phases (i.e., mid-luteal and pre-menstrual in women) correspond to distinct ovarian hormone profiles (i.e., low estradiol or high estradiol coupled with high progesterone) that are known to have stimulatory effects on eating behavior and have been associated with increased risk for emotional eating and binge eating. Nonetheless, other specific components of dysregulated eating (e.g., preoccupation with food, loss of control over eating) that are related to and/or prospectively predict the development of clinical binge eating …

Memory And Stereotypes For Lesbian/Gay Characters, Amber Rose Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

Stereotype-consistency bias refers to the idea that people tend to remember stereotypical information about others better than non-stereotypical information (Fyock & Stangor, 1994). Limited research has examined how people may use stereotype-consistency bias when recalling information about LGBT characters in narratives (Bellezza & Bower, 1981; Clark & Woll, 1981; McGann & Goodwin, 2007; Snyder & Uranowitz, 1978). This line of research suggests that, instead of genuinely remembering stereotypical information better, participants tended to guess stereotypical answers to questions they do not know. In contrast to those studies, the experiment I conducted for this thesis suggests that heterosexual young adults tend …

The Effects Of Somatosensory Input On Gait In Individuals Post-Stroke, Victor Hung, Amanda Reilly, Rachel Wood, Nikita Yuskov

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Stroke is a leading cause of disability that results in various neurological deficits, one of which is hemiplegia. This deficit alters the gait cycle, resulting in decreased propulsion force by plantar flexor muscles, decreased activation of dorsiflexor (DF) muscles, and increased coactivation of antagonistic ankle muscles. Stroke also leads to altered somatosensory input which results in decreased balance and gait speed, ultimately increasing fall risk. Therapies targeting increased somatosensory input have been shown to be beneficial in stroke as well as other neurological populations. However, no known studies have investigated the acute effects of local vibration to …
