The Effects Of A Moisture-Wicking Fabric Shirt On The Physiological Responses During Acute Exercise In The Heat, Kimberly Wigboldy
The Effects Of A Moisture-Wicking Fabric Shirt On The Physiological Responses During Acute Exercise In The Heat, Kimberly Wigboldy
Masters Theses
The purpose of this study is to investigate the effects that a form fitted, moisture-wicking fabric shirt, promoted to have improved evaporative and ventilation properties, has on the thermoregulatory, physiological and perceptual response during moderate intensity exercise in the heat for an extended duration of exercise of 90 minutes. Ten healthy subjects (7 males, 3 females), completed two heat stress tests consisting of 20 minute seated rest in a neutral environment (24°C, 60% RH), 30 minute seated rest in a hot environment (33°C, 60% RH), and 90 minutes of exercise(50% V02 peak) on a magnetically-braked cycle ergometerin a …
Use Of A Specific Alpha7 Nicotinic Acetylcholine Receptor Agonist Can Prevent Loss Of Retinal Ganglion Cells In An In Vivo Rat Glaucoma Model, David Mata
Masters Theses
Acetylcholine (ACh) has been shown to have a neuroprotective effect against glutamate-induced excitotoxicity in cultured retinal ganglion cells (RGCs) through activation of α7 nicotinic ACh receptors (nAChRs). In this study, the neuroprotective effects of the α7 nAChR agonist, PNU-282987, were investigated using an in vivo model of glaucoma in adult Long Evans rats. Hypertonic saline injections were used to induce a glaucoma model. After one month, retinas were removed, flat mounted, fixed and labeled with an antibody against Thy 1.1 to label RGCs and fluorescently tagged for visualization. Eye drop application of PNU-282987 resulted in neuroprotection against RGC loss in …
Expression Of The Chemokine Receptor, Cxcr4, And Its Ligand, Sdf-1, Are Increased In Purkinje Cells Of The Multiple System Atrophy Cerebellum, Megan Welter
Masters Theses
Multiple System Atrophy (MSA) is a sporadic, neurodegenerative disease that consists of three conditions: autonomic dysfunction, Parkinsonism and cerebellar ataxia. Our lab conducted an Affymetrix global gene expression analysis using pons tissue of MSA patients to determine genes that are differentially expressed when compared to non- MSA controls. This study identified upregulated genes, including the C-X-C chemokine receptor type 4, CXCR4, to which stromal cell-derived factor-I (SDF-1) is the natural ligand. The CXCR4/SDF-1 signaling pair has been sho.wn to play multiple roles in the brain, such as inducing neuronal apoptosis and promoting leukocyte recruitment during inflammation. The MSA cerebellum presents …
Explicit Teacher-Implemented Phoneme Awareness Instruction: Preschool Effects, Heather M. Osterhouse
Explicit Teacher-Implemented Phoneme Awareness Instruction: Preschool Effects, Heather M. Osterhouse
Masters Theses
The purpose of the current study was to investigate the impact of explicit, concentrated, teacher-implemented phonological awareness instruction for ―at risk‖ 4- year-olds. Early childhood educators were trained to implement a 10-week program delivered for 20-minute sessions, four times a week, in their classrooms. The program focused on phonological awareness beginning at the level of letter-sound knowledge and advancing to blending and segmenting constituent phonemes in words. Pre- to post-treatment comparisons of phonological awareness and letter knowledge skills indicated that children in the experimental group made significant gains in comparison to the control group in phoneme blending and letter knowledge. …
Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite
Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite
Masters Theses
The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …
A Discursive Analysis Of A Pregnancy Center: How Pregnant Women Are Encouraged To Develop A Sense Of Self-Worth And Emotional Wellbeing Through The Use Of Rhetoric And Imagery, Jessica Postma
Masters Theses
This study presents and alternative approach to how pregnancy is interpreted in western society and how settings such as a pregnancy center both challenges and reinforces these social standards. The promotion of abstinence, the aversion to abortion, notions of truth and morality, religious narratives, and the standard of care are all integral components to this analysis of pregnancy, language, and culture.
A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys
A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys
Masters Theses
A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …
Study Of The Insulin Mimetic Sodium Orthovanadate In Glucosamine Induced Insulin Resistnace In Primary Rat Hepatocytes, Kalan Mcpherson
Study Of The Insulin Mimetic Sodium Orthovanadate In Glucosamine Induced Insulin Resistnace In Primary Rat Hepatocytes, Kalan Mcpherson
Masters Theses
Insulin resistance and type II diabetes is a disease state characterized by a lack of sensitivity of insulin to provoke a proper response in insulin sensitive tissues. Currently, we utilize glucosamine to increase flux through the Hexosamine Biosynthetic Pathway (HBP) to induce an insulin resistance like state in primary rat hepatocytes. We tested the effectiveness of the insulin mimetic sodium orthovanadate to determine if it could elicit an insulin-like response under these conditions. Mixed results were obtained on the effectiveness of vanadate as an insulin mimetic in this insulin resistant model.
A Content Analysis Of Music Therapy Theses And Dissertations From 2000 To 2012 From Amta Approved Graduate Programs, Liisa G. Flores
A Content Analysis Of Music Therapy Theses And Dissertations From 2000 To 2012 From Amta Approved Graduate Programs, Liisa G. Flores
Masters Theses
The purpose of this content analysis was to categorize, code, and analyze trends related to graduate music therapy theses/dissertations completed from the year 2000 to 2012. Information was gathered related to what American Music Therapy Association (AMTA) approved schools have graduate programs and how many students have graduated from these institutions. Research questions addressed in this study were to determine (1) who were the thesis/dissertation advisors for students, (2) what was the type of goal for the research, (3) what types of studies were completed, and (4) what populations were studied.
Results included 35 schools offering graduate music therapy degrees. …
Preschoolers With Speech And Language Impairment: Case Studies From A Teacher-Delivered Phonological Awareness Program, Katherine J. Wickham
Preschoolers With Speech And Language Impairment: Case Studies From A Teacher-Delivered Phonological Awareness Program, Katherine J. Wickham
Masters Theses
Past and present research demonstrates early reading success related to phonological awareness (PA) instruction conducted individually or in small groups outside of the preschool classroom. This study investigated the effects of an explicit, intensive and teacher-delivered PA instruction for children with speech sound disorder and language impairment as part of the preschool curriculum. The investigator examined the performance of individual cases in both groups, those who received instruction and the control. Two participants in each of the experimental (E1 and E2) and control (C1 and C2) groups had standardized scores indicating deficits in speech and/or language. These children who received …
