Closing The Loop: A Study Of How The National Survey Of Student Engagement (Nsse) Is Used For Decision-Making And Planning In Student Affairs, Jennifer Lee Mccaul

Dissertations

“Closing the loop” is a commonly used phrase in discussing cyclical processes, such as the area of outcomes assessment in higher education. Increased interest in accountability and a shift in accreditation focus have necessitated that higher education institutions are closing the assessment loop and creating a culture of evidence to demonstrate that programs and services are having the intended impact, and using resources effectively. That culture includes both academic and co-curricular elements of the student experience. This research examined if, and to what extent, student affairs administrators use the National Survey of Student Engagement (NSSE)—one of the most prominent instruments …

© 2015 The Authors. Published by Elsevier B.V.. Vitamin D is getting more attention everyday due to its importance in maintaining bone and calcium homeostasis, cellular proliferation, differentiation and immune response. Vitamin D is derived from diet or elicited in the skin by the activation of 7-dehydrocholesterol, which is an inert molecule that must be activated by ultraviolet light to form pre-vitamin D3. Recent studies connected the gene encoding for vitamin D (VDR) to the genetic control of bone mass and other diseases. As VDR SNPs have been associated with several disorders and diseases, it's important to investigate the allelic …

Changes In Acoustic And Kinematic Articulatory Working Space Across Three Intensity Levels, Panika Ellis Palmer

Theses and Dissertations

The purpose of this study was to compare changes in acoustic and kinematic measures of articulation across soft, comfortable, and loud speech conditions. There were 19 participants, 9 male and 10 female, with age ranging from 20 to 34 with a median age of 25. Each participant had electromagnetic sensors glued to their tongue, jaw, and lips. It was anticipated that the acoustic measures would accurately reflect the kinematic measures of speech as articulation changed across the intensity levels. Vowel space area (VSA) and vowel articulation index (VAI) were computed from the three corner vowels, /α, i, u/. Articulatory-acoustic vowel …

The Effect Of Aerobic Exercise Versus Inactivity On Nitric Oxide Concentration And Synthesis In An Elderly Population, Samantha Burton

Theses and Dissertations

CONTEXT: Nitric Oxide (NO) is an endothelial-derived vasoactive molecule that causes an increase in blood flow and oxygen delivery to tissue. A reduction in NO bioavailability has been found to occur in adults over the age of 60 and can be reversed pharmacologically by improving NO synthase (NOS) activity. Reversing these age-related changes with alternative interventions, such as aerobic exercise, has shown some promising results. OBJECTIVE: To quantify blood NO-bioavailability (as measured by blood nitrite levels) in a population of aerobically trained elderly men and compare these data to a group of age-matched, inactive individuals. In addition, we measured the …

Water Use Of Four Commonly Planted Landscape Tree Species In A Semi-Arid Suburban Environment, Michael Cameron Bunnell

Theses and Dissertations

Native plant communities and agricultural land are commonly converted to urban areas as cities across the Western United States continue to grow and expand. This expansion is typically accompanied by afforestation where a common goal among communities is to maximize shade tree composition. Planted forests in these regions are commonly composed of introduced tree species native to mesic environments and their ability to persist is dependent on consistent irrigation inputs. Many potential ecosystem services may be derived from planting trees in urban and suburban areas; however, there are also costs associated with extensive afforestation, and shade tree cover may have …

Virulence Of Photorhabdus Spp.: Examining The Roles Of Environment, Evolution, And Genetics In Insect Mortality, Dana Blackburn

Theses and Dissertations

Entomopathogenic nematodes (EPNs) (genera Heterorhabditis and Steinernema) kill their invertebrate hosts with the aid of a mutualistic bacterium. The bacteria (Xenorhabdus spp. for steinernematids and Photorhabdus spp. for heterorhabditids) are primarily responsible for killing the host and providing the nematodes with nutrition and defense against secondary invaders. Photorhabdus is a Gram-negative bacterium in the Enterobacteriaceae family with high virulence towards their insect hosts. To achieve high mortality rates Photorhabdus produces a variety of virulence factors such as toxins, lipases, proteases, secretion systems, and fimbriae. EPNs are amenable to laboratory rearing and mass production for biocontrol applications against insects …

Hand-Portable Capillary Liquid Chromatography Instrumentation, Sonika Sharma

Theses and Dissertations

This dissertation focuses on the development of hand-portable capillary liquid chromatography (LC) instrumentation. In this work, battery-operable nano-flow pumping systems (isocratic and gradient) were developed and integrated with portable UV-absorption detectors for capillary LC. The systems were reduced in size to acceptable weights and power usage for field operation. A major advantage of the pumps is that they do not employ a splitter, since they were specifically designed for capillary column use, thereby greatly reducing solvent consumption and waste generation. UV-absorption detectors were specifically designed and optimized for on-column detection to minimize extra-column band broadening. Initially, an isocratic nano-flow pumping …

High Flow Air Sampler For Rapid Analysis Of Volatile And Semi-Volatile Organic Compounds, Xiaofeng Xie

Theses and Dissertations

Volatile and semi-volatile organic compounds are ubiquitous, and some of them are hazardous. The ability to rapidly detect and identify trace levels of them in air has become increasingly important. The conventional device used today for sampling and concentrating them in air is thermal desorption tubes filled with specific sorbents, which can only collect air samples at flow rates of 100-200 mL/min. In order to detect low concentration (ppt level) VOC compounds, long sampling time (>2 h) and sensitive detection are required. At the same time, portable instrumentation for on-site analysis has been developing rapidly. The somewhat lower performance …

The Impact Of Multimorbidity On Adult Physical And Mental Health In Low- And Middle-Income Countries: What Does The Study On Global Ageing And Adult Health (Sage) Reveal?, P Arokiasamy, U Uttamacharya, K Jain, Rb Biritwum, Et Al

School of Psychology

BACKGROUND: Chronic diseases contribute a large share of disease burden in low- and middle-income countries (LMICs). Chronic diseases have a tendency to occur simultaneously and where there are two or more such conditions, this is termed as 'multimorbidity'. Multimorbidity is associated with adverse health outcomes, but limited research has been undertaken in LMICs. Therefore, this study examines the prevalence and correlates of multimorbidity as well as the associations between multimorbidity and self-rated health, activities of daily living (ADLs), quality of life, and depression across six LMICs. METHODS: Data was obtained from the WHO's Study on global AGEing and adult health …

Between Minds And Bodies: Some Insights About Creativity From Dance Improvisation, K Łucznik

School of Psychology

Observing dance improvisation provides a unique opportunity to understand how people collaborate together while creating. It is an opportunity to consider how new ideas appear, not simply from the internal processes of a single creator but rather from the interactions between the minds, bodies and the environment acting on and between a group of improvising dancers. Improvisational scores served in this study as a laboratory into group creativity. Using a video-stimulated recall method, which asks dancers to reflect upon their own processes just after completing the score, I explored the interdependency between meta-cognitive strategies such as imagery and sense awareness, …

Transcranial random noise stimulation (tRNS) is a form of non-invasive brain stimulation (NIBS) that has been shown to increase motor performance in simple motor tasks. The purpose of the present study was to determine the influence of tRNS on motor skill acquisition and learning in a complex, modified golf putting task in young adults. Twenty-four (n = 12 per group) healthy young adult males were allocated to either a tRNS group or a SHAM stimulation group. Both groups performed 6 trials of the golf putting task in a baseline testing block, followed by 4 practice blocks of 15 trials. The …

An Evidence Based Approach To Sepsis: Educational Program, Dolores Perez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Evidence-based guidelines for recognizing and treating sepsis have been available for decades, yet healthcare providers do not adhere to the recommendations. Sepsis can progress rapidly if not recognized early. Literature reports reveal that sepsis is the leading cause of death in non-cardiac intensive care units (ICUs), and it is one of the most expensive conditions to treat. A hospital in the Las Vegas, Nevada area had previously introduced sepsis management prescriptions in 2011 with no formal education of sepsis guidelines to nurses. The original hospital’s sepsis management prescription sets followed guidelines dated 2008. The purpose of this project was to …

Scardovia Wiggsiae Prevalence In Orthodontic Patients, Brandon Joseph Streiff

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dental caries has mainly been associated with Streptococcus, Lactobacillus, Actinomyces and Veillonella species. But in recent salivary studies a new cariogenic pathogen, has been identified. This new bacteria, Scardovia wiggsiae (SW), is currently being tested within the UNLV School of Dental Medicine patient population. Although these current studies are being conducted to study its prevalence in both pediatric and adult populations, it has not been evaluated among patients with an altered oral environment as seen in patients with orthodontic appliances. Fixed orthodontic appliances increase the difficulty of removing daily plaque on and in between the teeth with standard oral hygiene …

Intraventricular Sialidase Administration Enhances Gm1 Ganglioside Expression And Is Partially Neuroprotective In A Mouse Model Of Parkinson's Disease., Jay S Schneider, Thomas N Seyfried, Hyo-S Choi, Sarah Kidd

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Preclinical and clinical studies have previously shown that systemic administration of GM1 ganglioside has neuroprotective and neurorestorative properties in Parkinson's disease (PD) models and in PD patients. However, the clinical development of GM1 for PD has been hampered by its animal origin (GM1 used in previous studies was extracted from bovine brains), limited bioavailability, and limited blood brain barrier penetrance following systemic administration.

OBJECTIVE: To assess an alternative therapeutic approach to systemic administration of brain-derived GM1 to enhance GM1 levels in the brain via enzymatic conversion of polysialogangliosides into GM1 and to assess the neuroprotective potential of this approach. …

Influence Of Child Injury Risk Perceptions On Adult Supervision Behavior, Ha Huynh

Master's Projects and Capstones

Parenting practices play an important role in child safety and injury prevention, and inadequate supervision poses a significant threat to child health. Intervention programs targeting injury beliefs have been shown to positively reduce risky play in children though these efforts vary with age and context. There is a need to further evaluate the influence of social context, environmental characteristics, and parenting practices on supervision behavior. Research has classified supervision characteristics based on dimensions of attention (level of interaction with the child and visual/auditory attentiveness), proximity (physical touch and distance to a child), and continuity (frequency/timing of supervision). Prior studies suggest …

Effectively Communicating Corporate Social Responsibility Initiatives: A Case Study, Razaz Banoun

Theses and Dissertations

The execution of a corporate social responsibility (CSR) strategy requires that companies maintain clarity in communication of their objectives to the public. The core reason for doing this is so that the companies are not misconstrued on the basis of their intentions. Commonly, people have tended to raise suspicions based on the sudden goodwill of corporations performing well in terms of their profit ratings, given that they are perceived as having a hidden agenda in relation to their active engagements in CSR. This case study has sought to highlight the various ways that are applied by Samsung Inc. to communicate …
