Induction Of Nafld With Increased Risk Of Obesity And Chronic Diseases In Developed Countries, Ian J. Martins

Research outputs 2014 to 2021

The susceptibility of individuals to obesity has been reported in many developed countries with predisposition of humans to obesity associated with high calorie diets and unhealthy lifestyles. Obesity may closely be involved in cell suicide in various organ diseases with the importance of accelerated aging that requires early intervention with drug therapy to prevent diseases such as non alcoholic fatty liver disease (NAFLD) that has increased in children and reached to approx. 40% of the global population. Obesity is induced by various diets and lifestyle factors such as stress, anxiety and depression which are important to consider with the global …

The first one-on-one interview occurred during the early stages of the participants’ heart journey, explored their heart story and use of interactive technology for heart health support. The second interview occurred six to twelve months later, and …

Identification Of Plasma Lipid Biomarkers In Alzheimer's Disease, Rhona Creegan

Theses: Doctorates and Masters

Alzheimer’s disease (AD), the commonest form of dementia, is a chronic, progressive neurodegenerative disease which manifests clinically as a slow global decline in cognitive function, including deterioration of memory, reasoning, abstraction, language and emotional stability, culminating in a patient with end-stage disease, totally dependent on custodial care. With an ageing population, there is predicted to be a marked increase in the number of people diagnosed with AD in the coming decades, making this a significant challenge to socio-economic policy and aged care. Currently there is no cure for AD and while current therapies may temporarily ameliorate symptoms, death usually occurs …

Preventing Maternal And Early Childhood Obesity: The Fetal Flaw In Australian Perinatal Care, Margaret R. Miller, Lydia A. Hearn, Paige Van Der Plight, Jane Willcox, Karen Campbell

Research outputs 2013

Almost half of Australian women of child-bearing age are overweight or obese, with a rate of 30–50% reported in early pregnancy. Maternal adiposity is a costly challenge for Australian obstetric care, with associated serious maternal and neonatal complications. Excess gestational weight gain is an important predictor of offspring adiposity into adulthood and higher maternal weight later in life. Current public health and perinatal care approaches in Australia do not adequately address excess perinatal maternal weight or gestational weight gain. This paper argues that the failure of primary health-care providers to offer systematic advice and support regarding women’s weight and related …

Averting Uncertainty: A Practical Guide To Physical Activity Research In Australian Schools, Jerome N. Rachele, Thomas F. Cuddihy, Tracy L. Washington, Steven M. Mcphail

Australian Journal of Teacher Education

Preventative health has become central to contemporary health care, identifying youth physical activity as a key factor in determining health and functioning. Schools offer a unique research setting due to distinctive methodological circumstances. However, school-based researchers face several obstacles in their endeavour to complete successful research investigations; often confronted with complex research designs and methodological procedures that are not easily amenable to school contexts. The purpose of this paper is to provide a practical guide for teachers (both teacher educators and teaching practitioners) seeking to conduct physical activity-based research in Australian school settings, as well as discuss research practices. The …

Online Healthy Lifestyle Support In The Perinatal Period: What Do Women Want And Do They Use It?, Lydia A. Hearn, Margaret R. Miller, Anna Fletcher

Research outputs 2013

Unhealthy weight gain and retention during pregnancy and postpartum is detrimental to mother and child. Although various barriers limit the capacity for perinatal health care providers (PHCPs) to offer healthy lifestyle counselling, they could guide women to appropriate online resources. This paper presents a project designed to provide online information to promote healthy lifestyles in the perinatal period. Focus groups or interviews were held with 116 perinatal women and 76 PHCPs to determine what online information perinatal women and PHCPs want, in what form, and how best it should be presented. The results indicated that women wanted smartphone applications (apps) …

Tools For Sustainability: Water Footprints, John Hannan

Landscapes: the Journal of the International Centre for Landscape and Language

There have been significant global developments in water footprinting in the past few years and a growing adoption and application of the water footprint concept to improve water management outcomes. This article provides an overview of the principles and ideas underlying water footprints and their current status in sanctioned water dialogue and governance in Australia. Arguments are advanced as to why and how water footprint initiatives generally, and water footprint labelling of consumer products specifically, can contribute to the efficient use and sustainability of freshwater resources. The article concludes that any initiative will require both the cooperation and goodwill of …

Everywhere And Nowhere, Liana Christensen

Landscapes: the Journal of the International Centre for Landscape and Language

In 1788 Europeans arrived here to stay. Since then, between eighteen and twenty mammal species have been lost, depending on who‘s counting. Gone, too, are the Paradise Parrot and the Dwarf Emu. Alarmingly high numbers of animal (and plant) species hover just this side of oblivion. Not infrequently in Australia‘s natural history the first sighting of an animal by a colonial collector is followed fairly swiftly by a long disappearance. Very few come back. For the most part, expanding populations of exotic predators and feral competitors, combined with shrinking islands of natural habitats mean that the average Australian has few …

Searching For Health Information On The Internet : The Experiences Of Western Australian Adolescents, Lee-Anne Martins

Theses : Honours

Adolescents readily engage in online entertainment pursuits, however, it is their online social activities and health information searches that encourage psychosocial development and influence identity formation and autonomy. Considerable research has been completed on various aspects of adolescents’ encounters with online health information (for example, see Percheski & Hargittai, 2011), yet minimal research has been conducted using Australian adolescents. This study extends existing research utilising Western Australian adolescents who have used the Internet to obtain health information. The areas explored include how Western Australian adolescents search for online health information, by means of which devices, and their experiences of using …

Tackling Overweight And Obesity: Does The Public Health Message Match The Science?, Katherine Hafekost, David Lawrence, Francis Mitrou, Therese O'Sullivan, Stephen R. Zubrick

Research outputs 2013

Background

Despite the increasing understanding of the mechanisms relating to weight loss and maintenance, there are currently no validated public health interventions that are able to achieve sustained long-term weight loss or to stem the increasing prevalence of obesity in the population. We aimed to examine the models of energy balance underpinning current research about weight-loss intervention from the field of public health, and to determine whether they are consistent with the model provided by basic science. EMBASE was searched for papers published in 2011 on weight-loss interventions. We extracted details of the population, nature of the intervention, and key …

How Mean Is The Mean?, Craig P. Speelman, Marek Mcgann

Research outputs 2013

In this paper we voice concerns about the uncritical manner in which the mean is often used as a summary statistic in psychological research. We identify a number of implicit assumptions underlying the use of the mean and argue that the fragility of these assumptions should be more carefully considered. We examine some of the ways in which the potential violation of these assumptions can lead us into significant theoretical and methodological error. Illustrations of alternative models of research already extant within Psychology are used to explore methods of research less mean-dependent and suggest that a critical assessment of the …

The expressed needs of women were matched to behaviour change theory to guide development of the Healthy You Healthy Baby website and Smartphone application. A mix of factual and practical online information, self-assessment, goal-setting and feedback …

Molecular Insights Into Appetite Control And Neuroendocrine Disease As Risk Factors For Chronic Diseases In Western Countries, I J. Martins, Rhona Creegan, W. L. F. Lim, Ralph Martins

Research outputs 2013

Environmental factors such as stress, anxiety and depression are important to consider with the global increase in chronic diseases such as cardiovascular diseases, cancer, stroke, obesity, diabetes and neurodegenerative diseases. Brain metabolic diseases associated with conditions such as obesity and diabetes require early intervention with diet, lifestyle and drug therapy to prevent diseases to various organs such as the liver with non alcoholic fatty liver disease (NAFLD) and other organs such as the heart, lungs thyroid, pancreas, brain, kidneys and reproductive systems. Behavioural stress and the molecular mechanisms that are involved in neuroendocrine diseases such as insulin resistance in obesity …

Review Of Ear Health And Hearing Among Indigenous Australians, Jane F. Burns, Neil J. Thomson

Research outputs 2013

Indigenous Australians experience some of the highest levels of ear disease and hearing loss in the world, with rates up to ten times more than those for non-Indigenous Australians [4]. Children and adolescents are particularly vulnerable to ear infections. The most common ear disease among Indigenous children is otitis media (OM), which is inflammation/infection of the middle ear typically caused by bacterial and viral pathogens. Indigenous children living in urban, rural and, particularly, remote areas, are more likely than their non-Indigenous counterparts to have OM at younger ages, more often, at a greater level of severity, and with more likelihood …

Approach-Iron Play In High Performance Golf: From Testing To Tournament Play, Samuel John Robertson

Theses: Doctorates and Masters

The capability of a golfer to record a low score depends upon well-developed abilities in each of the recognised on-course skill components (driving the ball off the tee, hitting approach-iron shots, hitting short-iron shots and putting). Despite approach-iron play being considered perhaps the most important and definitely the most practiced skill in the game, the ability to quantify the golfer’s ability to hit approach-iron shots in a controlled, off-course environment (eg. training) cannot yet be undertaken due to the lack of appropriate assessments. Such tools have considerable potential for use in both the field and in research for implementation in …

Herbivory By Parma Mccullochi (Pomacentridae) : Its Role As An Ecosystem Engineer In Temperate Algal-Dominated Reefs, Frederico Vitelli

Theses: Doctorates and Masters

Pomacentridae is one of the most representative families of herbivorous fishes inhabiting both tropical and temperate reefs, yet the vast majority of studies examining feeding within this family have been undertaken in tropical rather than temperate regions. Despite the high abundances of the pomacentrid Parma mccullochi in temperate waters of Western Australia, and their likely importance in removing algae from reefs in the region, there is a lack of information on their diet and their impact on the reef algal community. This study aims to determine the role of Parma mccullochi as an ecosystem engineer on temperate algal-dominated reefs in …

Understanding And Disrupting Institutional Settings : Using Networks Of Conversations To Re-Imagine Future Farming Lives, Robert Campbell

Theses: Doctorates and Masters

Farmers in Australia and elsewhere face the challenge of remaining profitable whilst dealing with adverse structural arrangements and public expectations to better manage environmental degradation. This thesis draws on arguments that dominant paradigms in agricultural science and environmental management have often been ineffective in addressing these apparently competing demands and appear poorly suited to ‘messy’ situations characterized by uncertainty and complexity, and in which diverse stakeholders are motivated by varying goals and values. Engaging with such situations requires a philosophy and methodology that accepts a multiplicity of perspectives and which seeks to learn about and reflect upon novel ways of …

Somewhat Damaged And Interrogating The Incubus : Sleep Paralysis Explored In The Young Adult Novel, 'Somewhat Damaged', Lauren Payne

Theses : Honours

This thesis, comprising an excerpt from my young adult paranormal novel ‘Somewhat Damaged’ and an essay, examines the mythic potential of sleep paralysis, a paralytic transitory state between sleep and consciousness during which frightening hallucinations are projected onto the waking environment. While the neurophysiology is generally agreed upon, further investigation is warranted on the anomalous phenomena that manifests during sleep paralysis hallucinations. Within the theoretical framework of psychoanalysis, particularly Carl Jung’s collective unconscious theory (1959), I will imaginatively explore the recurring figure of the ‘incubus’ of sleep paralysis that has provoked ubiquitous fear and ambiguity. The essay will describe the …

Self-Efficacy And Nutrition Knowledge Of Parents In Western Australia, Karen Lombardi

Theses : Honours

Background: Poor dietary choices and increasingly sedentary lifestyles mean childhood obesity is an increasing problem. Parents have the capacity to significantly affect the food choice of children; therefore by improving their self-efficacy, their nutrition knowledge, attitudes and behaviour, and by providing access to sound nutritional information, the health of children may be improved.

Purpose: This research sought to gather preliminary information required to inform the development of nutrition education materials for parents, which will parallel those currently under development for teaching children in schools as part of the Australian curriculum. Research has demonstrated that while educating children about healthy eating …

Smaller, Faster Stomata: Scaling Of Stomatal Size, Rate Of Response, And Stomatal Conductance, Paul Drake, Raymond H. Froend, Peter Franks

Research outputs 2013

Maximum and minimum stomatal conductance, as well as stomatal size and rate of response, are known to vary widely across plant species, but the functional relationship between these static and dynamic stomatal properties is unknown. The objective of this study was to test three hypotheses: (i) operating stomatal conductance under standard conditions (gop) correlates with minimum stomatal conductance prior to morning light [gmin(dawn)]; (ii) stomatal size (S) is negatively correlated with gop and the maximum rate of stomatal opening in response to light, (dg/dt)max; and (iii) gop correlates negatively with instantaneous water-use efficiency (WUE) despite positive correlations with maximum rate …

Application Of Glycyrrhiza Glabra Root As A Novel Adsorbent In The Removal Of Toluene Vapors: Equilibrium, Kinetic, And Thermodynamic Study, Fazel Mohammadi-Moghadam, Mohammad Mehdi Amin,, Mehdi Khiadani, Fariborz Momenbeik, Heshmatollah Nourmoradi, Mohammad Sadegh Hatamipour

Research outputs 2013

The aim of this paper is to investigate the removal of toluene from gaseous solution through Glycyrrhiza glabra root (GGR) as a waste material. The batch adsorption experiments were conducted at various conditions including contact time, adsorbate concentration, humidity, and temperature. The adsorption capacity was increased by raising the sorbent humidity up to 50 percent. The adsorption of toluene was also increased over contact time by 12 h when the sorbent was saturated. The pseudo-second-order kinetic model and Freundlich model fitted the adsorption data better than other kinetic and isotherm models, respectively. The Dubinin-Radushkevich (D-R) isotherm also showed that the …

Brief Oral Health Promotion Intervention Among Parents Of Young Children To Reduce Early Childhood Dental Decay, Peter Arrow, Joseph Raheb, Margaret Miller

Research outputs 2013

Background: Severe untreated dental decay affects a child's growth, body weight, quality of life as well as cognitive development, and the effects extend beyond the child to the family, the community and the health care system. Early health behavioural factors, including dietary practices and eating patterns, can play a major role in the initiation and development of oral diseases, particularly dental caries. The parent/caregiver, usually the mother, has a critical role in the adoption of protective health care behaviours and parental feeding practices strongly influence children's eating behaviours. This study will test if an early oral health promotion intervention through …
