An Exploration Of How And Why Primary Care Providers Educate Infant Caregivers About Positioning, Amy Greenspon Choffin
An Exploration Of How And Why Primary Care Providers Educate Infant Caregivers About Positioning, Amy Greenspon Choffin
Theses and Dissertations
A review of the literature indicates that how infants are positioned is related to the risk of SIDS, the incidence and severity of plagiocephaly, torticollis, and developmental delays. A quantitative approach with survey methodology was used with 66 pediatric primary care providers responding to 26 questions. Overall, PCPs are educating caregivers about sleep positioning with a high frequency. There was a relationship between practice site, and the frequency of sleep positioning education is provided. While the participants provide education about awake positioning, and the use of positioning devices, it was with less frequency than they do about sleep positioning; there …
Parent And Therapist Perceptions Of Sensory Based Strategies Used By Occupational Therapists In Family-Centered Early Intervention Practice, Juliet Bertaut Copeland
Parent And Therapist Perceptions Of Sensory Based Strategies Used By Occupational Therapists In Family-Centered Early Intervention Practice, Juliet Bertaut Copeland
Theses and Dissertations
A qualitative approach was used to explore the perceptions of parents and therapists in early intervention regarding sensory diets and their efficacy, particularly their goodness of fit within family routines and occupations. Open-ended interviews were conducted with therapist and parent participants and analysis of the data resulted in a model depicting how sensory diets became a "way of life" for families. The Sensory Diet "Way of Life" Model revealed seven themes that illustrated how occupational therapists in early intervention enter the homes of the families they serve and establish a "partnership" with parents to address a child's needs. Once this …
Autocrine Effects Of Catecholamines On Macrophage Release Of Interleukin-6 (Il-6), Shaunta D. Poe
Autocrine Effects Of Catecholamines On Macrophage Release Of Interleukin-6 (Il-6), Shaunta D. Poe
Theses and Dissertations
Effects of norepinephrine (NE) on macrophage cytokine release are complex because the cells have both α2 and β2 adrenergic receptors, which mediate opposing actions. Furthermore, β2-adrenergic agonists are reported to have both stimulatory and inhibitory effects on interleukin-6 (IL-6). This study was designed to clarify the autocrine role of macrophage-derived NE on IL-6 production in activated peritoneal macrophages. Effects of NE on IL-6 production in the RAW264.7 macrophage cell-line also were investigated. Treatment of activated peritoneal macrophages with endotoxin, the α2-adrenergic antagonists yohimbine or RS79948 revealed that the α2-adrenergic receptor mediates a stimulatory autocrine action of catecholamines on IL-6 production. …
Functional Redistribution Of Hippocampal Cannabinoid Cb1 Receptors In The Rat Pilocarpine Model Of Acquired Epilepsy, Katherine Winslow Falenski
Functional Redistribution Of Hippocampal Cannabinoid Cb1 Receptors In The Rat Pilocarpine Model Of Acquired Epilepsy, Katherine Winslow Falenski
Theses and Dissertations
Cannabinoids, such as the marijuana derivative Δ9-THC, are known to have CBl receptor-mediated anticonvulsant effects in several animal models of seizures and epilepsy, including the rat pilocarpine model of acquired epilepsy. However, the distribution of CBl receptor expression and function in brains of epileptic rats has not been characterized. Therefore, this dissertation was initiated to evaluate the effect of epileptogenesis on the distribution and function of the endogenous CBI receptor system in the rat pilocarpine model, a well-established model of acquired temporal lobe epilepsy. Using immunohistochemistry, we demonstrated that chronically epileptic rats exhibit a unique, long-term, and specific redistribution of …

Delayed Versus Immediate Feedback In An Independent Study High School Setting, Duane C. Lemley
Theses and Dissertations
Although there is general agreement that feedback plays an important role in student performance, the majority of the studies found in the research literature explore the impact of different types of feedback in a traditional and university-level setting. In order to explore the impact of different feedback types in a non-traditional distance learning setting, 352 high school students enrolled in courses offered through BYU's Independent Study (IS) department received either delayed feedback or immediate feedback generated by Speedback™, BYU's automated grading and feedback program, depending on whether they had opted to submit end of unit assignments by mail or …
Toward A Domain Theory Of Fluent Oral Reading With Expression, Reo H. Mcbride
Toward A Domain Theory Of Fluent Oral Reading With Expression, Reo H. Mcbride
Theses and Dissertations
Today's educators are in need of tests or rating systems that provide specific and valid feedback to parents, students and programs. This need includes the area of expressive fluent oral reading. One way to address this need is to provide a rating system based on theoretical models that explore how fluency develops. This study explores the dimensions, constructs, or aspects that make up fluency. It also explores whether there is a sequence or order in how fluent oral reading with expression develops and the theoretical reasons for that ordering. This study further addresses whether word recognition or accuracy confounds the …

Evaluation Of Chitosan Gelatin Complex Scaffolds For Articular Cartilage Tissue Engineering, Harshal Prabhakar Mahajan
Evaluation Of Chitosan Gelatin Complex Scaffolds For Articular Cartilage Tissue Engineering, Harshal Prabhakar Mahajan
Theses and Dissertations
In search of better scaffolding materials for in vitro culture of chondrocytes, the combination of chitosan (similar to glycosoaminoglycans) and gelatin (denatured collagen) was tested due to its resemblance to cartilage extra-cellular matrix (ECM). Porous scaffolds were fabricated from chitosan gelatin blends (1:1, 2:1, and 3:1). The response of chondrocytes to them was evaluated from the amount of sulphated GAG and collagen type 2 secreted after 3 and 5 weeks. The effect due to static (transwell inserts) and dynamic (rotating bioreactor) culture methods was analyzed. Results indicate that 1:1 chitosan gelatin blends showed the best chondro-conductive potential. The rotating bioreactor …

Testing The Floristic Quality Assessment Index In Natural And Created Wetlands In Mississippi, Usa, Brook Danielle Herman
Theses and Dissertations
The U.S. Environmental Protection Agency has mandated that states must include the use of biological assessments in their water quality laws to assess the biological integrity of aquatic systems. The Floristic Quality Assessment Index (FQAI), which uses wetland vegetation to assess the biological integrity of an ecosystem, has not been tested in Mississippi. The purpose of this study was to test the efficiency of the FQAI in wetlands along a gradient of human influence. Coefficients of conservatism (CC) were assigned to plant species based on their tolerance to disturbance and fidelity to habitat. A negative correlation was found between the …
Individualistic Roamers Or Community Builders?:Differences And Boundaries Among Rvers, Gloria Anne Mattingly
Individualistic Roamers Or Community Builders?:Differences And Boundaries Among Rvers, Gloria Anne Mattingly
Theses and Dissertations
The number of leisure and working RVers roaming America?s highways, now conservatively estimated at over eight million, continues to increase (Curtin 2001; Sommer 2003). In spite of their growing presence and unique lifestyle, these populations remain sociologically understudied. This exploratory case study of two distinctly different RV parks is a small but significant step toward filling that research gap. At both RV parks I found a diverse population of individualists who value self-contained travel, freedom, relaxation, and sociality. In spite of sharing a collective, subcultural lifestyle, they differed along multiple axes. Marked differences separate RVers into three broad groups (full-timers, …
How Coming To Terms With Difficulties In The Family Of Origin Positively Influences Adult Children's Relationship/Marital Quality, Vjollca Kadi Martinson
How Coming To Terms With Difficulties In The Family Of Origin Positively Influences Adult Children's Relationship/Marital Quality, Vjollca Kadi Martinson
Theses and Dissertations
Decades of research have shown that family-of-origin experiences are generally important predictors of individuals' later relationship/marital quality. On average, the healthier these experiences are, the healthier adult children's relationships and marriages tend to be. The focus of this study was to investigate how coming to terms with difficulties experienced in the family of origin may enhance adult children's ability to create high quality relationships and marriages. The study employed a sample of 6423 U.S. couples, 18-45 years old, who were dating, cohabitating, engaged or married. This study showed that individuals in couple relationships who reported healthier family-of-origin experiences and those …
