Research outputs 2014 to 2021

The present study determined the effects of muscular endurance strength training on maximum strength and power, functional capacity, muscle activation and hypertrophy in older men and women. Eighty-one men and women acted as an intervention group while 22 acted as non-training controls (age range 64-75 y). Intervention training included super-sets (i.e., paired exercises, immediately performing the second exercises following completion of the first) with short rest intervals (30-60 s between sets) at an intensity of 50-60% one-repetition maximum (1-RM) for 15-20 repetitions. Concentric leg press actions measured maximum strength (1-RM) and concentric peak power. Functional capacity was assessed by maximum …

Commercially Available Digital Game Technology In The Classroom: Improving Automaticity In Mental-Maths In Primary-Aged Students., John O'Rourke, Susan Main, Susan M. Hill

Australian Journal of Teacher Education

In this paper we report on a study of the implementation of handheld game consoles (HGCs) in 10 Year four/five classrooms to develop student automaticity of mathematical calculations. The automaticity of mathematical calculations was compared for those students using the HGC and those being taught using traditional teaching methods. Over a school term, students (n=236) who used the HGCs and Dr Kawashima’s Brain Training showed significant improvement in both the speed and accuracy of their mathematical calculations. Data collected in interviews during the intervention period from students, staff and parents were analysed to provide further information on the implementation and …

Regulation Of Core Body Temperature And The Immune System Determines Species Longevity, Ian J. Martins

Research outputs 2014 to 2021

The anti-aging gene Sirtuin 1 has now major relevance to genetics and the fields of pharmacology, toxicology, neuroscience, immunology, biochemistry and cell/molecular biology. Advances in anti-aging therapy are now essential to prevent mitochondrial apoptosis to promote longevity with the prevention of accelerated ageing. Calorie restriction that maintains the anti-aging gens changes the core body temperature and promotes species longevity. Stress and calorie consumption are sensitive to Sirt 1 function with relevance heat shock protein 70 metabolism and mitochondrial biogenesis. Sirt 1 regulation of the circadian rhythm mediates melatonin effects on core body temperature regulation and immune responses. Diet and fat …

Unsupervised Monitoring Of An Elderly Person's Activities Of Daily Living Using Kinect Sensors And A Power Meter, Hossein Pazhoumand-Dar

Theses: Doctorates and Masters

The need for greater independence amongst the growing population of elderly people has made the concept of “ageing in place” an important area of research. Remote home monitoring strategies help the elderly deal with challenges involved in ageing in place and performing the activities of daily living (ADLs) independently. These monitoring approaches typically involve the use of several sensors, attached to the environment or person, in order to acquire data about the ADLs of the occupant being monitored.

Some key drawbacks associated with many of the ADL monitoring approaches proposed for the elderly living alone need to be addressed. These …

Towards Active Ageing: A Comparative Study Of Experiences Of Older Ghanaians In Australia And Ghana, Daniel Doh

Theses: Doctorates and Masters

Population ageing has become a central feature of the 21st century, as most countries search for economically viable strategies to support and manage their ageing populations to live in a dignified way. In 2002, the World Health Organisation (WHO) proposed the active ageing policy framework to guide countries to develop policies that promote the quality of life for their older people. However, the interpretation and application of the active ageing model in the literature and policy discussions are inconclusive on the most important elements that promote the quality of life of older people. The discussions have largely focused on health …

Feasibility Of Presurgical Exercise In Men With Prostate Cancer Undergoing Prostatectomy, Favil Singh, Robert Newton, Michael Baker, Nigel Spry, Dennis Taaffe, Jeffery Thavaseelan, Daniel A. Galvao

Research outputs 2014 to 2021

Background:

Prostatectomy is associated with short- and long-term morbidity, which includes attenuation of muscle function and deterioration of lean body mass. Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy.

Methods:

Ten men (68+6.4 years old) with localized PCa undertook a 6-week resistance and aerobic exercise program prior surgery. Training was undertaken twice weekly and patients were assessed at baseline, presurgery, and …

Magnesium Therapy Prevents Senescence With The Reversal Of Diabetes And Alzheimer’S Disease, Ian James Martins

Research outputs 2014 to 2021

In the current global epidemic for Non Alcoholic Fatty Liver Disease (NAFLD), diabetes and neurodegenerative diseases such as Alzheimer’s disease there has been a major interest in magnesium therapy to delay the severity of NAFLD, Type 3 diabetes and neurodegeneration in the developing and developed world. The objective of magnesium therapy is to activate the anti-aging gene Sirtuin 1 (Sirt1) to prevent cardiovascular disease, NAFLD and diabetes. Reduced consumption of nutrients such as fatty acids, glucose, cholesterol and increased magnesium consumption is closely linked to reduced bacterial lipopolysaccharides (LPS) and activation of Sirt1 relevant to active nuclear and mitochondria interactions …

Research outputs 2014 to 2021

Impaired strength adversely influences an older person’s ability to perform activities of daily living. A cross-sectional study of 117 independently living men and women (age = 73.4 ± 9.4 year; body mass index (BMI) = 27.6 ± 4.8 kg/m2) aimed to assess the association between body composition and: (1) upper body strength (handgrip strength, HGS); (2) lower extremity performance (timed up and go (TUG) and sit to stand test (STS)); and (3) endurance (6-minute walk (SMWT). Body composition (% fat; lean body mass (LBM)) was assessed using bioelectrical impedance. Habitual physical activity was measured using the Minnesota Leisure Time Physical …

Loyalty Cards And The Problem Of Captcha: 2nd Tier Security And Usability Issues For Senior Citizens, David M. Cook, Apoorv Kumar, Charwina Unmar-Satiah

Australian Information Security Management Conference

Information Security often works in antipathy to access and useability in communities of older citizens. Whilst security features are required to prevent the disclosure of information, some security tools have a deleterious effect upon users, resulting in insecure practices. Security becomes unfit for purpose where users prefer to abandon applications and online benefits in favour of non-digital authentication and verification requirements. For some, the ability to read letters and symbols from a distorted image is a decidedly more difficult task than for others, and the resulting level of security from CAPTCHA tests is not consistent from person to person. This …

Defining Young In The Context Of Prostate Cancer, Suzanne Chambers, Anthony Lowe, Melissa Hyde, Leah Zajdlewicz, Robert F. Gardiner, David Sandoe, Jeff Dunn

Research outputs 2014 to 2021

The experience of prostate cancer is for most men a major life stress with the psychological burden of this disease falling more heavily on those who are younger. Despite this, being young as it applies to prostate cancer is not yet clearly defined with varied chronological approaches applied. However, men’s responses to health crises are closely bound to life course and masculinities from which social roles emerge. This paper applied qualitative methodology (structured focus groups and semistructured interviews with expert informants) using interpretative phenomenological analysis to define what it means to be young and have prostate cancer. Structured focus groups …

Sexuality, Desire And The Ageing Female Body: An Essay, Lauren Marsh

Theses: Doctorates and Masters

This thesis consists of a novella, ‘One Night in Hong Kong’, and an essay, ‘Sexuality, Desire and the Ageing Female Body.’ The novella tells the story of an erotic affair between the female narrator and a man in a hotel room in the neon city of Hong Kong. Told in four parts, the story shifts in time, reflecting on earlier events in the narrator’s life and a trip she made to the Sicilian city of Catania in 1954.

Older female protagonists and their sexuality are rarely depicted in contemporary Australian fiction. Where representations do exist, they act as ‘interventionist’ texts, …

Physical Educators’ Efficacy In Utilising Paraprofessionals In An Inclusive Setting, Scott J. Pedersen, Paul D. Cooley, Clint R. Rottier

Australian Journal of Teacher Education

Inclusion of students with disabilities (SwD) in Australian health and physical education (HPE) classes is on the rise. Reasonable adjustment to assist inclusive practice is often accomplished through the use of teaching assistants, or paraprofessionals. While this practice is commonly understood within the classroom, this approach remains obscure in the HPE setting. The purpose of this study was to explore how Australian HPE teachers utilise paraprofessionals when teaching SwD in inclusive environments. HPE teachers (N=14) completed an online questionnaire inquiring how paraprofessionals are being used and the strategies they are using to develop working relationships with paraprofessionals. The …

Parkinson's Diagnosis From The Caregiver's Perspective, Helen Maree Bradley

Theses : Honours

Parkinson’s disease (Parkinson’s) is a progressive neurodegenerative disorder. The irreversible and accumulating disability experienced means that people with Parkinson’s progressively lose their autonomy, eventually requiring complete care. Consequently, Parkinson’s significantly impacts sufferers and the people who care for them. Informal care, predominantly provided by female spouses becomes exceptionally demanding over time, and caregivers experience significant morbidity. Stress manifests across all stages of the caregiving trajectory, with diagnosis reported as a particularly stressful period for caregivers; however, few attempts have been made to understand what makes it stressful. The current study explored female spousal caregivers’ subjective experience of the Parkinson’s diagnosis, …

Social Engagement, Setting And Alcohol Use Among A Sample Of Older Australians, Julie Dare, Celia Wilkinson, Steve Allsop, Stacey Waters, Sheila Mchale

Research outputs 2014 to 2021

The harms associated with risky alcohol consumption have long been researched and recognised in the health field. However, little available research has focused on older people, or extended analysis of alcohol use by this segment of the population beyond a bio-medical perspective. With the rapid ageing of the global population, research that investigates alcohol use amongst older people from a social perspective is important. This article reports on research with a group of older women and men, to identify and explain factors that influence alcohol consumption. In-depth interviews were conducted in Perth, Western Australia with 20 men and 22 women …

An Investigation Into The Psychological Impact Of Informal Aged Care: The Lived Experience Of Older Female Informal Aged Carers, Emma Stein

Theses : Honours

It has been estimated that 196,000 (38%) informal carers in Australia are aged over 65 years, with the majority of these carers providing care to someone in their own age group. In particular, it is women who have been providing most informal care. Recognition of this has highlighted women’s needs for psychological support in their caregiving roles. However, research into women’s experiences of this phenomenon is scarce. The present study aimed to explore the lived experiences of women in this context, asking the question “what are the perceived psychological impacts of aged care on older women who are informal carers?” …

Motherless Mothers: Maternally Bereaved Women In Their Everyday Roles As Mothers, Bethwyn Rowe, Bronwyn A. Harman

Research outputs 2014 to 2021

Motherless mothers are women who lose their mothers to death prior to having their children, and therefore raise their children without the maternal support and guidance afforded to many women whose mothers are still alive (Edelman, 2006). A qualitative research design was used to gain an in-depth understanding of the everyday experiences faced by motherless mothers. Semi-structured, in-depth interviews were conducted with 10 motherless mothers. Four major themes emerged including grief, support, absence of knowledge, and changes to self following loss. Results provide insight into the ongoing influence a mother's death can have on a daughter's life and draw distinction …

Decreased Serum Zinc Is An Effect Of Ageing And Not Alzheimer's Disease, Alan Rembach, Dominic Hare, James Doecke, Samantha Burnham, Irene Volitakis, Christopher Fowler, Robert Cherny, Catriona Mclean, Rudolf Grimm, Ralph N. Martins, David Ames, Colin Masters, Ashley Bush, Blaine Roberts

Research outputs 2014 to 2021

We examined the distribution of zinc in the periphery (erythrocytes and serum) in a large, well-characterised cohort, the Australian Imaging, Biomarkers and Lifestyle (AIBL) study, in order to determine if there is systemic perturbation in zinc homeostasis in Alzheimer’s disease (AD). We observed an age dependent decrease in serum zinc of approximately 0.4% per year. When correcting for the age dependent decline in serum zinc no significant difference between healthy controls (HC), mildly cognitively impaired (MCI) or AD subjects was observed.

“Keeping It Together, Keeping Their Heads Above Water”: Western Australian Child Health Nurses’ Understanding Of Resilience In Postpartum Mothers, Rachael O. Collins, Julie Ann Pooley, Myra F. Taylor

Research outputs 2014 to 2021

Assessing the well-being of postpartum mothers is an important aspect of postnatal nursing care. For this reason, Child Health Nurses (CHNs) are charged with the responsibility of identifying postpartum mothers who do/not manifest resilient behavioral qualities. However, little is known about CHNs’ conceptualization of resilience or how they assess resilience in postpartum mothers. This exemplar study addressed this knowledge shortfall by conducting semi-structured interviews with eight practicing CHNs. The study’s findings reveal that although CHNs’ conceptual understanding of resilience is congruent with current theoretical thinking, some variance does exist in the ways in which CHNs assess postpartum resilience, particularly, in …

Perceptions Of Five-Year Competitive Categories: Model Of How Relative Age Influences Competitiveness In Masters Sport, Nikola Medic, Bradley Young, J. Robert Grove

Research outputs 2013

The purpose of this study was to examine the contrasting perceptions of masters swimmers related to the first and fifth constituent years of a 5-year age category. Swimmers aged between 35 and 93 years (154 male, 184 female) were surveyed at the 2008 FINA World Masters Championships. Exploratory factor analysis indicated the existence of the following five factors considered important for preparation, attendance, and success at masters competitions: awareness of advantages, expectancy, motivation, training, and physiological capacity. One sample ttests showed that masters swimmers are conscious of advantages that 5-year age categories afford to relatively-younger cohorts (i.e., those who are …

Exploring Wellbeing In Older Male Farmers In Western Australia, Jessica L. Mckee

Theses : Honours

In the context of an ageing population it has become increasingly important to identify the determinants of wellbeing in older adulthood. A review of the literature relevant to wellbeing and strengths relevant to older male farmers in Australia was conducted. This body of knowledge was identified to be sparse. Existing literature on farming primarily had a deficits focus, and only a small number of qualitative studies were specific to older male farmers. Four broad, overlapping areas representing the meaning of wellbeing were identified as potentially important: farming work; connectedness; the land; health and wellbeing. The inter-connected nature of farming life …

Glycosylation of immunoglobulin G (IgG) influences IgG effector function by modulating binding to Fc receptors. To identify genetic loci associated with IgG glycosylation, we quantitated N-linked IgG glycans using two approaches. After isolating IgG from human plasma, we performed 77 quantitative measurements of N-glycosylation using ultra-performance liquid chromatography (UPLC) in 2,247 individuals from four European discovery populations. In parallel, we measured IgG N-glycans using MALDI-TOF mass spectrometry (MS) in a replication cohort of 1,848 Europeans. Meta-analysis of genome-wide association study (GWAS) results identified 9 genome-wide significant loci (P,2.2761029) in the discovery analysis and two of the same loci (B4GALT1 and …

The Acceleration Of Aging And Alzheimer’S Disease Through The Biological Mechanisms Behind Obesity And Type Ii Diabetes, Ian J. Martins, Wei Ling F. Lim, Andrea C. Wilson, Simon M. Laws, Ralph Martins

Research outputs 2013

The incidence of diabetes is predicted to increase to 21% by 2050. Currently, one third of US adults are obese and over 11% of these individuals have diabetes. Due to the growing need for therapeutic intervention to control and/or stabilize this increase in the incidence of diabetes in Western communities, gaining a comprehensive understanding of the association between obesity and Type 2 diabetes has become increasingly important to diabetes research. The increased cell senescence associated with diabetes has been associated with the limited ability of cells to divide, with indication of telomere shortening and genomic instability of the cells. Obese …

Nutritional Narratives: Cultural And Communications Perspectives On Plant-Based Diets, Julie S. Dare, Leesa N. Costello, Lelia R. Green

Research outputs 2013

This paper responds to a range of popular materials circulating in the public sphere asserting a plant-based (PB) diet is of benefit to humans and a protection against many chronic diseases. Although directed at a lay audience, books such as The China Study (Campbell & Campbell) are based upon extensive academic research, and highlight multiple health, environmental and social advantages of PB diets over traditional western diets. Arguments advocating PB nutrition, however, generally struggle to achieve traction in the public sphere. Narratives around PB food choices, and difficulties in shifting mainstream eating patterns, reflect the cultural symbolism attached to food, …

Recruitment Discrimination Against Middle Eastern People In Western Australia : The Case Of Accountants, Tiny Pinkerton

Theses : Honours

The population of all Western countries are ageing and humanitarian efforts saw increasing numbers of people from Middle Eastern origin settle in Australia. Whilst older people are encouraged to remain in paid employment longer, it is not clear whether Middle Eastern people and the older population are as readily hired as are Anglo Australians and the younger population. Pairs of fictitious, unsolicited job applications were used to test for age and racial discrimination of Middle Eastern people in the Western Australian labour market. The study employed a 2 x 2 between subjects design with race (Anglo Australian and Middle Eastern) …

Reflective Writing In Pre-Service Teachers' Teaching: What Does It Promote?, Etty Cohen-Sayag, Dita Fischl

Australian Journal of Teacher Education

In this study, we examined changes in levels of pre service teachers' reflective writing and tried to identify links between these changes and pre service teachers' success in teaching. Participants were two groups of pre-service special education teachers that taught in two different special education settings:learning difficulties classes and multiple and profound intellectual disabilities classes. Data collection was performed during two consecutive academic semesters, including a monthly structured journal about teaching events during field experience and summative grades, assessing pre service teachers' teaching activities for each semester. Journal analysis referred to three reflective levels of explanations, descriptive, comparative and critical. …

Pet Loss And The Elderly, Daphne D’Gama

School of Psychology and Social Science Presentations

Companion animals are known to provide numerous psychosocial benefits to their owners. It is due to these prominent and positive contributions that individuals develop a deep attachment with their pet. Consequently pet owners experience intense grief reactions following the death of a cherished pet. While numerous studies have focused on the experiences for children and young adults, the experience of pet loss for the elderly remains relatively unexplored. An in-depth qualitative research design guided by a phenomenological framework was used to explore the experiences surrounding pet loss for the elderly. Data was collected though one-on-one semi-structured interviews with thirteen participants …
