Exercise, Learning And Emotional Health: Interdisciplinary Approaches To Translational Action, Tessa L. Koschel
Exercise, Learning And Emotional Health: Interdisciplinary Approaches To Translational Action, Tessa L. Koschel
UNLV Theses, Dissertations, Professional Papers, and Capstones
Exercise positively effects physical, psychological and neurological wellbeing. Though the population at large is becoming increasingly aware of the multi-faceted benefits of exercise, the majority of people fail to meet daily exercise recommendations. Largely, demands of everyday life such as work, school and family take priority over fitness. The issue therefore becomes a matter of time. In a world of media multi-tasking and immediate gratification, the challenge to health professionals becomes incorporation and manipulation of these consistencies to improve exercise uptake and adherence. Focus must shift from the idea of making additional time for exercise, to adding exercise to time …
Dietary Intake And Energy Expenditure Of Pararescuemen During Routine Training, Andrea Woita
Dietary Intake And Energy Expenditure Of Pararescuemen During Routine Training, Andrea Woita
UNLV Theses, Dissertations, Professional Papers, and Capstones
Pararescuemen are one group of Air Force Special Operations Forces (SOF) who engage in vigorous physical training to achieve mission readiness. This type of training requires high energy expenditures and matching dietary intake to support basic physiological needs and to meet performance demands. However, few studies have investigated the energy expenditure and dietary intake of SOF and none have specifically examined these behaviors in Pararescuemen. The goal of this investigation was to determine the energy expenditure and dietary intake of Pararescuemen during routine training - a period when these operators receive supervision and guidance for performance improvements, recovery, and career …
An Evaluation Of Gabab Receptors On Modulating Neuroinflammation In A Non-Transgenic Animal Model Of Alzheimer's Disease, Monica Bolton
An Evaluation Of Gabab Receptors On Modulating Neuroinflammation In A Non-Transgenic Animal Model Of Alzheimer's Disease, Monica Bolton

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by progressive memory loss and distinct neuropathological hallmarks, including amyloid beta plaques and neurofibrillary tau tangles (NFT). Although the etiology remains to be discovered, several risk factors exist that significantly contribute to developing AD. Diabetes is one of the major risk factors associated with AD and is characterized by disrupted insulin signaling that may contribute to or exacerbate AD pathologies. Furthermore, both disorders result in increased neuroinflammation. Considerable evidence has demonstrated that a chronic inflammatory response, in particular chronic microglia activation, promotes A production as well as the hyperphosphorylation of tau through …
The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce
The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce

Theories considering the etiology of psychopathy suggest that trauma exposure, specifically childhood maltreatment and sexual abuse, is related to the development of callous-unemotional traits in children and adolescents, which are precursors to psychopathic traits in adulthood. Furthermore, posttraumatic stress disorder has an opposite relationship with many of the emotional and behavioral components of the two-factor model of psychopathy. Specifically, PTSD is positively associated to IA and traits associated with it and negatively associated with FD. Thus, this study sought to expand upon the current theories of a trauma-based etiology of psychopathy by investigating the relationship between trauma, PTSD, and psychopathic …

Neural Processes Underlying Auditory Context Effects, Breanne Yerkes
UNLV Theses, Dissertations, Professional Papers, and Capstones
Auditory information within our natural environments is disorganized and often ambiguous, leaving our auditory systems with a complex task: organizing sound into coherent objects. The auditory system uses both current and prior information to assist in completing this task. The influences of previous context on current perception have been referred to as context effects. A contrastive context effect results in a current perception that is opposite of what is expected based on the physical stimulus properties presented during an immediate context. A facilitative context effect results in a current perception that is the same as the perception during the immediate …
Factors Influencing Induction Of Desiccation Tolerance In Bryophytes: Redefining Fundamental Aspects Of The Organism’S Relationship With The Environment In Xeric Habitats, Joshua Lee Greenwood
Factors Influencing Induction Of Desiccation Tolerance In Bryophytes: Redefining Fundamental Aspects Of The Organism’S Relationship With The Environment In Xeric Habitats, Joshua Lee Greenwood
UNLV Theses, Dissertations, Professional Papers, and Capstones
If one wishes to understand the ecological role, range, habitat preferences, selective pressures, reproduction, response to climate change, and the potential for survival under climactic change, range expansion and range contraction for species and populations of bryophytes, an understanding of their survival of the desiccated state, is essential. In order to further our understanding of desiccation tolerance in mosses, three projects were undertaken. The first of these investigated the nature of desiccation tolerance in mosses, specifically if desiccation tolerance can be induced; thereby providing a desiccation tolerant phenotype in a moss species generally considered desiccation sensitive (Physcomitrella patens, the model …
Thermal And Developmental Ecology Of Pupfish, Cyprinodon, Alexander Jones
Thermal And Developmental Ecology Of Pupfish, Cyprinodon, Alexander Jones
UNLV Theses, Dissertations, Professional Papers, and Capstones
Pupfish from the genus Cyprinodon are among the most endangered groups of fishes on the planet, with nearly 40% of species being threatened with extinction. These pupfishes are often assumed to be the most temperature tolerant of all fish, coping with temperatures as low as 0 °C and as high as 44 °C. However, conflicting data exist and certain measures of thermal tolerance are not markedly higher in pupfish compared to common game fish. Pupfish egg production and growth has been known to be hampered at temperatures well below what they apparently experience in nature. I addressed why eggs fail …
