A Descriptive Survey Of Undergraduate Nursing Students' Perceptions Of Desirable Leadership Qualities Of Nurse Preceptors, Melanie Zilembo

Theses : Honours

Leadership in the nursing profession has gained much attention over the previous decade. However, there is a paucity of literature examining the context of leadership within the clinical preceptor/undergraduate nursing student relationship and the relevance of this to the clinical learning environment. Globally, the nursing profession is experiencing a climbing attrition rate, an accelerating ageing workforce and a trend toward part-time employment. Practical experience is based upon a preceptored model of supervision creating a potential for inconsistencies for student supervision and assessment within this mode of education. The purpose of this study was to explore, from the perspective of the …

Do Auditory Simulations Of Noise-Induced Hearing Loss Change Young Adults' Attitudes Towards Noise Exposure?, Claire Roockley

Theses : Honours

Noise-induced hearing loss (NIHL), or hearing damage from regular exposure to loud noise, can profoundly affect a person's hearing capabilities and overall well-being. Many individuals continue to expose themselves to hazardous levels of noise, and, in turn, put themselves at risk of developing a NIHL. This review critically examines the existing literature presented on NIHL. Emphasis is placed on the increasing prevalence of NIHL in young adults from exposure to loud recreational noise. The effectiveness of current educational strategies that have been employed to reduce or prevent the occurrence of NIHL in this cohort is also examined. Research indicates that …

The Prediction Of Antenatal And Postnatal Depression In A Sample Of Western Australian Women, Debbie A. Lien

Theses: Doctorates and Masters

In Australia, the Edinburgh Postnatal Depression Scale (EPDS; Cox, Holden & Sagovsky, 1987) has been increasingly used to screen for antenatal depression prior to its evaluation on a sample of Australian pregnant women. Also, the identification of predictors associated with antenatal depression has been neglected relative to the research focus on postpartum depression. An aim of the study was to evaluate the antenatal screening properties of the EPDS against diagnoses of major depression with the Mini International Neuropsychiatric Interview (MINI; Sheehan eta!., 1998). The aims were also to develop predictive models of risk factors associated with antenatal depression as measured …

LSU Doctoral Dissertations

Haemonchus contortus is one of the major nematode parasites causing substantial economic losses in small ruminant farming worldwide. Recently, effect of anthelmintic treatment has decreased due to an increasing problem of nematode populations that have developed resistance to anthelmintics. There are certain breeds of sheep that are identified as being relatively resistant to the parasite including Gulf Coast Native (Native) sheep. Understanding the mode of immune response that helps these breeds of sheep control infection could help design vaccines and enhance control programs. This experiment was designed to evaluate the immunological responses of Native, compared with susceptible Suffolk sheep that …

Effect Of Adapted Phonic Faces Story Books On Phonological Skills Of Children With Severe Expressive Language Disorders, Meher Hormazd Banajee

LSU Doctoral Dissertations

Although No Child Left Behind (2001) encourages the inclusion of all children within the regular curriculum, children with severe speech and physical disabilities rarely are provided with the literacy education provided to grade-level peers. This study taught alphabetic skills to three children with severe speech and physical impairments in the context of traditional alphabet books versus Phonic Faces Storybooks. Both storybooks were converted into e-books using Microsoft Office PowerPoint (Microsoft Office, 2003) and accessed using a single rocking lever switch. Two graphemes were selected based on incorrect responses from the pretest administration of the The Phonological Awareness Test (Roberson & …

Expectation In Auditory Processing Of Environmental Sounds In People With Fluent Aphasia, Meghan Evelyn Collins

LSU Master's Theses

The purpose of this study was to examine the integrity of the nonverbal auditory system in subjects with fluent aphasia, and determine the relative preservation of the nonverbal auditory system in comparison to the lexical system. This was attempted through the task of expectation, a high level processing skill. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged individuals. Participants were administered two nonverbal auditory conditions devoid of lexical information, a simple condition and a complex condition in which they were required to determine if the last sound heard in a sequence …

Role Of Heparanase And Heparanase-Degraded Heparan Sulfate In Brain-Metastatic Melanoma, Madhuchhanda Roy

LSU Doctoral Dissertations

Cancer metastasis is a frequent manifestation of malignant melanoma progression. Successful invasion into distant organs by tumor cells must include attachment to microvessel endothelial cells, and degradation of extracellular matrix. Heparan sulfate proteoglycans are ubiquitous macromolecules associated with cell surface and extracellular matrix of a wide range of cells and tissues. Heparanase is an extracellular matrix degradative enzyme which degrades the heparan sulfate chains of heparan sulfate proteoglycans. To investigate effects of changes in heparanase gene expression in metastatic melanoma cells, we constructed adenoviral vectors containing the full-length human heparanase cDNA in both sense (Ad-S/hep) and anti-sense orientations (Ad-AS/hep). We …

Alphabetic And Phonemic Awareness In Toddlers, Pamela A. Terrell

LSU Doctoral Dissertations

The ability of 20-24 month-old toddlers to recognize graphemes and phonemes was investigated by reading a Phonic Faces (PF) alphabet picture book. Phonic Faces iconically picture a letter in the mouth of a character producing the sound (the curve of the P looks like the top lip popping the /p/ sound). The book was composed of nine letters and was read individually to experimental subjects three times weekly for six weeks. The control group received no treatment, but engaged in individual play activities for comparable time. Following six-weeks the groups alternated so the former control group now received the alphabet …

Brucella Melitensis: The Evaluation Of A Putative Hemagglutinin Gene's Effect On Virulence In The Caprine Model, Quinesha Laticia Perry

LSU Doctoral Dissertations

Brucella melitensis is a facultative intracellular bacterial pathogen that causes abortions in goats and sheep and Malta fever in humans. The zoonotic disease brucellosis causes severe economic losses in the Mediterranean region and parts of Africa, Asia, and Latin America. With the completion of the genomic sequences of B. abortus 2308 and B. melitensis 16M, no classical virulence factors were found; and the chromosomes were virtually identical. However, in B. melitensis, a putative hemagglutinin gene was identified which is absent in B. abortus. The possibility of the hemagglutinin gene being a potential virulence factor was evaluated via gene replacement/deletion in …

P-Glycoprotein And Membrane Permeability As Determinants Of Xenobiotic Bioavailability And Bioaccumulation, Xiaobing Tan

LSU Doctoral Dissertations

The ABC transporter P-glycoprotein (Pgp) and membrane permeability are determinant factors for absorption and disposition of xenobiotics. These studies investigated the effects of potential modulators of Pgp and/or membrane function on the disposition, bioavailability and bioaccumulation of environmentally relevant pharmaceuticals, tetracycline and ivermectin, and the carcinogen benzo[a]pyrene in catfish. The pesticide dieldrin and surfactant linear alkylbenzene sulfonate (LAS) were selected as mixture components thought to have potential interactions with these determinants of disposition. Initial in situ experiments demonstrated dieldrin and tetracycline both significantly inhibited biliary excretion of Pgp prototypic substrate Rhodamine-123 in isolated perfused livers. Further, dieldrin (20µM) reduced movement …

Rate Change Effects On Acoustic Duration Measures On An Adolescent Who Stutters, Valerie Jean Courville

LSU Master's Theses

The purpose of this study was to determine if reduced rate techniques have an effect on speech motor coordination of an adolescent. A literature review revealed that a reduced rate technique consistently promoted more fluent speech; however, the cause of that increase in fluency is not known. This study proposed three specific questions to determine if there was a shortening of the /s/ phoneme in clustered contexts when compared to singletons, if reducing the rate would cause the adolescent to produce more adult-like shortening patterns, and if the reduced rate technique caused a decrease in stuttering events. One eleven year …

The second phase of the study included interviews that were collected from 17 families …

Characterization Of A Virulence Related Hypothetical Protein In Edwardsiella Ictaluri, Ildiko Katalin Polyak

LSU Master's Theses

Although the biochemical characterization of E. ictaluri, the subsequent disease progression of enteric septicemia of catfish (ESC), and the associated pathologic lesions are well characterized, the mechanism of invasion of E. ictaluri into a susceptible host is poorly understood. Identification and confirmation of virulence factors and associated genes of E. ictaluri is crucial to elucidating the pathogenesis of this important disease. A signature tagged mutagenesis (STM) study conducted by Thune et al. (2006) identified 50 E. ictaluri clones with transposon insertions in genes potentially involved in pathogenesis. A specific STM mutant, 233PR, carrying a transposon insertion in a gene encoding …

Influence Of Tumor Necrosis Factor-Alpha And Minocycline On Microglia And Macrophage Activation During Polytropic Retrovirus Infection, Meryll E. Corbin

LSU Master's Theses

Microglia/macrophage activation has been associated with the pathogenesis of various neurological diseases including human immunodeficiency virus encephalitis, transmissible spongiform encephalitis, and Alzheimer's disease (AD). In vitro studies have indicated a role for TNFα in activating these cells which leads to their migration, proliferation, and secretion of proinflammatory cytokines and chemokines that may potentially damage brain tissue. In the current study, we analyzed the phenotype of microglia and macrophages enriched from wild type and TNFα deficient mice infected with a neurovirulent murine retrovirus. Although TNF receptors CD120a and CD120b were expressed on both microglia and macrophage population, unaltered by either retrovirus …

From Gps To Psychologists: The Patients' Perspective On Help-Seeking And Referral, Zdenka Bartova

Theses : Honours

The experience of living with psychological problems has a profound effect on an individual's life. For those actively seeking help, General Practitioners usually present the first point of contact. General Practitioners thus serve as gatekeepers who either decide to manage the individuals themselves and/or refer them to a mental health professional. The referral decision is part of a complex help-seeking process in which patients have to mediate their own understanding of their problems with that of the practitioner, all within the structural constraints of the current health care system. This literature review discusses constructs of mental illness and the impact …
