Interhemispheric Modulation Of Corticomotor Excitability Following I-Wave Periodicity Transcranial Magnetic Brain Stimulation (Itms), Lucy Catherine Millar

Theses : Honours

AIMS: Transcranial Magnetic Stimulation (TMS) has been recently demonstrated to have potential therapeutic benefits by promoting cortical plasticity through modulation of corticospinal excitability. We have previously shown in healthy adult subjects that paired-pulse TMS (1.5ms ISI) applied over Ml at 0.2Hz for 15min (known as iTMS), can raise corticospinal excitability for a period (~10min) that outlasts the intervention. Since interhemispheric changes in corticomotor excitability are considered to have fundamental importance in the control of voluntary movement, and recovery of motor function following unilateral damage, importance is placed on understanding the mechanisms involved. The aims of the current study were therefore …

Effect Of A Paediatric Incentive Spacer And Reinforcement Of Inhalation Technique Training In Preschool Children, Jasminka Murdzoska

Theses : Honours

Incorrect inhaled drug delivery technique is a common problem in paediatric asthma [1-4]. Previously, device technique training has been shown to significantly improve inhaler skills, using subjective methods, namely check-list analysis [5-8]. However, more objective measures are needed to examine more comprehensively the effect of training in preschool children and parents. Resistance to regular asthma therapy is also a frequent problem when attempting to treat young children. Reasoning with young children can be very difficult and parents often have to struggle with their child to achieve compliance [2]. The Funhaler spacer (FH) (Funhaler™; InfaMed, Australia) has been developed in an …

Sex Differentiation And Sexually Dimorphic Disease, Emily A. Jefferson

Theses : Honours

Sexual dimorphism of the central nervous system is a still widely debated and an area of much research. Conclusive evidence that anatomical and physiological differences in the CNS exist has been reported by post-mortem studies and magnetic resonance imaging (MRI). This present study seeks to contribute to the understanding of the differences in the brain between genders and to ascertain reasons as to why the literature is so varied. A number of structures such as the cerebral cortex, hypothalamic nuclei and the amygdala have proven to be significantly larger within males as opposed to females. The nuclei of the hypothalamus …

A Comparison Of Nurses' Clinical Judgement And The Short Form-Mini Nutritional Assessment Tool In Assessing The Nutritional Status Of Older Patients In An Acute Clinical Setting, Roger Shreeve

Theses : Honours

Decreased nutritional status of older hospitalised patients has been identified as a significant problem. The prevalence of malnutrition in older people has been reported to be between 17% and 65% in acute hospital settings. This has led to the recognition of a need for a valid instrument to adequately assess nutritional status. Tools developed to date still require much time and expertise to implement, limiting their use within the practical setting. Nurses are in an ideal position to conduct nutritional assessments. They possess clinical knowledge which can be utilised to provide individualised and timely assessment. To. date, the literature does …

Enrolled Nurses' Attitudes, Subjective Norms, Intentions And Behaviour Related To Independent Medication Administration, Donna Sayers

Theses : Honours

The purpose of this quantitative descriptive research study was to investigate Enrolled Nurses' attitudes, intentions and behaviour in relation to independent medication administration (IMA). This research was necessary as a significant number of Enrolled Nurses (ENs) are now able to administer medications up to Schedule Four level, without supervision when they have completed a medication administration programme (MAP). This change in the scope of practice for the EN will eventually be introduced nationally as recommended by the National Review of Nursing Education (2002). Anecdotal reports suggest that IMA is causing concern for the EN but little or no research has …

Nurses' Decision Making Processes Regarding Indwelling Catheter Insertion And Removal, Helen Hull

Theses : Honours

Urinary catheterisation remains a common procedure conducted by nurses often as a result of autonomous decision making. This research aimed to identify and describe the lived experience of nurses' decision making processes regarding the insertion and removal of urinary catheters. The research was believed to be important as there is a myriad of literature on what is best practice but very little on what is actually taking place in nursing practice. A qualitative phenomenological study design was chosen, where nurse participants were interviewed using open-ended questions. Descriptive phenomenology was the chosen method which follows in Heidegerr's tradition that allowed nurses …

Exploring The Notion Of Emotional Attachment In Orford's Model Of Addiction : Review, And A Step Towards Operationalising Orford's Concept Of Strong Attachment In Addiction : A Qualitative Study, Kate E. Baily

Theses : Honours

Orford's (2001) notion that a strong emotional attachment to an object (drug) or activity (gambling) is a central component of addiction has received little empirical attention. The published research on attachment to inanimate objects was reviewed and led to the following conclusions. First, attachment theory has been validly applied to people's relationships with inanimate objects. Second, researchers have developed technologies (e.g., psychological measures, operational definitions) to enable empirical research in this area. Third, this research is in its early phases, but has produced reliable standardised measures of people's emotional attachment to brands. Further research is needed to operationalise Orford's (2001) …

Why Undergraduate Nurses Choose Not To Pursue Mental Health Nursing As A Career In Western Australia : A Descriptive Study, Therese Howell

Theses : Honours

Not only are fewer undergraduate nursing students opting to pursue a career in mental health nursing (Arnswald, 1987; Clinton & Hazelton, 2000; Happell, 1998; Lam, McMaster & Troup, 1993), but nursing students continue to rank mental health nursing as their lowest preference of career choice. Instead, nursing undergraduates appear to be opting for positions within the surgical or critical care specialties (Durkin, 2002; Happell, 1999; Happell1999; Happell, 2001). The aim of this descriptive study was to investigate and identify the potential reasons why undergraduate nursing students do not take up mental health nursing as a career. This descriptive study implemented …

Neck Loading In High Performance Combat Pilots During Aerial Combat Manoeuvres And Specific Neck Strengthening Exercises, Kevin J. Netto

Theses: Doctorates and Masters

Background: Neck pain and injury is a common occurrence in high performance combat pilots (HPCP) around the world. The cause of this has been attributed to exposure to the unavoidable high mechanical loading related to the neck being positioned in non-neutral head postures whilst being exposed to moderate to high +Gz levels. Specific neck conditioning exercises have been proposed as being a possible method to decrease the incidence of neck pain and injury in this population. However, there has been sparsely published research examining the suitability of selected exercises for HPCP who participate in regular aerial combat manoeuvres (ACM).

Confined Space Fatalities, Ciaran Maccarron

Theses: Doctorates and Masters

The extent of work related fatal accidents has been analysed statistically by agencies throughout the world. As a result of this analysis there is a wealth of information available categorised by industry types, sub-industry, occupation, sex, age, nature of occurrence, bodily location, agency of occurrence and mechanism of injury. It is however extremely difficult to identify information pertaining to confined space fatalities such as contributory factors, mechanisms of injury and other data of an epidemiological nature.

Controlling Involvement To Promote Confidence In Palliative Care Decisions - A Grounded Theory From The Patient's Perspective, Susan F. Lee

Theses: Doctorates and Masters

Decision making in the context of palliative care is particularly complex given the unpredictable illness trajectories experienced by patients and the number of individuals who may be part of the decision making process. This grounded theory study explored and described from the perspective of patients with advanced illness, their experiences of making care decisions. A review of literature at the commencement of the study indicated that there was a lack of evidence to support the best way of ascertaining patient's preferences for involvement in decisions in a palliative care context and almost no research to guide clinicians about the involvement …

Networks And Narratives: An Exploration Of Their Relationship And Potential For Understanding The Actual Experiences Of Women With Hiv/Aids, Purity N. Irungu

Theses: Doctorates and Masters

This study set out to examine literature relating to social network theory and narrative theory in order to explore how their potential connection could be used in future to understand and improve the actual life-experiences of women infected by the Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS). The thesis was done entirely by library research using secondary sources but is original in its intent. It includes a critical examination of some of the work of earlier researchers, including Lockhart's (2000) anthropological study of the social construction of `risk' of AIDS in urban Tanzania. Much previous research studied …

Writing that includes stories about vulnerable people from another culture, …

Process Evaluation Of A School- And Home-Based Sun Safety Education Intervention, Robyn S. Johnston

Theses: Doctorates and Masters

Effective interventions that reduce children's sun exposure are likely to reduce melanoma incidence in the longer term. However, for such interventions to have an impact they must be adequately implemented. School-based sun protection programs have been evaluated to determine their effectiveness in changing behaviours, however, few studies have assessed the implementation of such programs, or the effect of their implementation on outcomes. Kidskin was a five-year intervention trial designed to assess the effectiveness of a multicomponent intervention in reducing sun exposure in children in Perth, Western Australia. This thesis describes the process evaluation of the school- and home-based educational components …

Exploring Young People's Concepts Of Smoking Addiction: Perceived Opportunities To Try Smoking Without Becoming Addicted, Calvin Wang

Theses: Doctorates and Masters

This study explores how young people conceptualise addiction to smoking and, also the relationship between young people's addiction beliefs and intentions to smoke cigarettes. Addiction to smoking is a major health problem, not just for adults, but also for young smokers, up to 60% of whom are dependent on nicotine. However, anti-smoking prevention efforts targeted at young people generally emphasise ill-health effects and little attention is paid to addiction education which is generally considered relevant only to adult smoking and cessation efforts. Perhaps as a consequence, young people appear to have many misconceptions and unrealistic ideas about addiction, and these …

A Case Study Investigation Of The Development And Treatment Of Alter Personalities In Dissociative Identity Disorder, Ian Brown

Theses: Doctorates and Masters

Progress in the study and treatment of Dissociative Identity Disorder (DID) has been hampered by ideological debate regarding its validity. This is particularly the case when patient's suffering from DID also report ritualistic abuse. Part of the difficulty has been that past studies have not established independent checks to assess whether alters are artefacts introduced by therapeutic bias. This study addressed this issue by using independent judges to test the validity of a patient being treated for DID who claimed ritualistic abuse. The judges were 16 clinicians with an average of 21 years experience in their respective disciplines. The study …

An Investigation Of The Effect Of Exercised Arm, Training Status, And Racial Background On Changes In Markers Of Muscle Damage Following Maximal Eccentric Exercise Of The Elbow Flexors, Michael J. Newton

Theses: Doctorates and Masters

Despite the substantial body of research accumulated on exercise-induced muscle damage, there remain several areas that warrant further investigation. Study groups comprised of individuals from differing racial background and /or training status have the potential to influence the intra-group variability in damage markers following eccentric exercise. In addition, if a contralateral arm model is employed, intra- and inter-group variation could be influenced by the formation of groups based on limb dominance and /or the order in which the arms are exercised. Currently there is a dearth of research addressing these factors, however, these types of studies are important as they …

Controlling And Constraining The Participation Of The Hepatitis C-Affected Community In Australia: A Critical Discourse Analysis Of The First National Hepatitis C Strategy And Selected News Media Texts, Judith D. Pugh

Theses: Doctorates and Masters

The construction of texts that place hepatitis C-positive persons at social risk (Candlin, 1989, p. ix), informs this study of the ways in which public health policy makers and journalists in Australia communicate about hepatitis C. The institutions of public health and the news media form part of the cultural context within which persons construct their illness narratives. The privileged perspectives and framing of public health policy and news media discourses; the discursive practices associated with the institutions of public health and the media around hepatitis C and hepatitis C-positive persons, the “objects” of knowledge (Foucault, 1969/2002, p. 81); and …

Effects Of Hypoxia On Exercise Induced Muscle Damage, Trevor M. Farr

Theses: Doctorates and Masters

The present study investigated the hypothesis that maximal voluntary contractions (MVC) peak torque, VJ, muscle tenderness, and plasma creatine activity would be significantly less for the condition that subjects were exposed to hypoxic (H) condition for 4 hours after eccentric exercise compared with the normoxic (N) condition.

Resistance Exercise In Men Receiving Androgen Deprivation Therapy For Prostate Cancer, Daniel A. Galvao

Theses: Doctorates and Masters

This thesis encompasses two literature reviews (chapter 2 & 3) and two experimental chapters (4 and 5) examining the available literature on exercise and cancer, resistance training and its anabolic responses in older men and women, the side effects of Androgen Deprivation Therapy (ADT) for prostate cancer and finally, the role of resistance exercise as a clinical intervention to counteract such changes as an adjuvant therapy.
