Intergenerational Influences Of Hunger And Community Violence On The Aboriginal People Of Western Australia: A Review, Francesca Robertson, David Coall, Dan Mcaullay, Alison Nannup

Research outputs 2014 to 2021

There is a consensus in the literature that hunger and community violence inaugurates adverse health impacts for survivors and for their descendants. The studied cohorts do not include Western Australian Aboriginal people, although many experienced violence and famine conditions as late as the 1970s. This article describes the pathways and intergenerational impacts of studied cohorts and applies these to the contemporary Western Australian context. The authors found that the intergenerational impacts, compounded by linguistic trauma, may be a contributor to current health issues experienced by Aboriginal people, but these are also contributing to the resurgence in population numbers.

High-Rise Apartments And Urban Mental Health—Historical And Contemporary Views, Danica-Lea Larcombe, Eddie Van Etten, Alan Logan, Susan L. Prescott, Pierre Horwitz

Research outputs 2014 to 2021

High-rise apartment buildings have long been associated with the poor mental health of their residents. The aims of this paper are to examine whether this connection is necessarily so, by reviewing the evidence relating to the relationships between high-rise living and social wellbeing, occupant’s stress levels, and the influence they have on mental health. From selected literature, psychological stress and poor mental health outcomes of the populations that live in high-rise apartments are indeed apparent, and this is particularly so for apartments in poor neighbourhoods. Yet many apartments in developed cities are in affluent areas (particularly those with views of …

Association Between Aortic Calcification, Cardiovascular Events, And Mortality In Kidney And Pancreas-Kidney Transplant Recipients, Joshua R. Lewis, Germaine Wong, Anne Taverniti, Mirna Vucak-Dzumhur, Grahame J. Elder

Research outputs 2014 to 2021

BACKGROUND: Cardiovascular (CV) disease is the leading cause of death in kidney and simultaneous pancreas-kidney (SPK) transplant recipients. Assessing abdominal aortic calcification (AAC), using lateral spine x-rays and the Kaupilla 24-point AAC (0-24) score, may identify transplant recipients at higher CV risk.

METHODS: Between the years 2000 and 2015, 413 kidney and 213 SPK first transplant recipients were scored for AAC at time of transplant and then followed for CV events (coronary heart, cerebrovascular, or peripheral vascular disease), graft-loss, and all-cause mortality.

RESULTS: The mean age was 44 ± 12 years (SD) with 275 (44%) having AAC (26% moderate: 1-7 …

Elucidating The Surface Geometric Design Of Hydrophobic Australian Eucalyptus Leaves: Experimental And Modeling Studies, Hua Guo, Zonghan Xie, Jeremy Shaw, Kingsley Dixon, Zhong-Tao Jiang, Chun-Yang Yin, Xuemei Liu

Research outputs 2014 to 2021

Three Australian native Eucalyptus species, i.e., Eucalyptus woodwardii, Eucalyptus pachyphylla and Eucalyptus dolorosa, were investigated, for the first time, with respect to the hydrophobicity of their leaves. It is well established that these leaves exhibit exceptionally high water repellency, in addition to an extraordinary ability to retain water, albeit their specific wetting mechanisms are still poorly understood. To identify the critical factors underlying this phenomenon, the surface topography of these leaves was subjected to micro-examination (SEM). Micro- and nanometer scale surface roughness was revealed, resembling that of the quintessential “lotus effect”. Surface free energy analysis was performed on two models …

Immunomagnetic-Enriched Subpopulations Of Melanoma Circulating Tumour Cells (Ctcs) Exhibit Distinct Transcriptome Profiles, Carlos Aya-Bonilla, Elin S. Gray, Jayapal Manikandan, James B. Freeman, Pauline Zaenker, Anna L. Reid, Muhammad A. Khattak, Markus H. Frank, Michael Millward, Mel Ziman

Research outputs 2014 to 2021

Cutaneous melanoma circulating tumour cells (CTCs) are phenotypically and molecularly heterogeneous. We profiled the gene expression of CTC subpopulations immunomagnetic-captured by targeting either the melanoma-associated marker, MCSP, or the melanoma-initiating marker, ABCB5. Firstly, the expression of a subset of melanoma genes was investigated by RT-PCR in MCSP-enriched and ABCB5-enriched CTCs isolated from a total of 59 blood draws from 39 melanoma cases. Of these, 6 MCSP-and 6 ABCB5-enriched CTC fractions were further analysed using a genome-wide gene expression microarray. The transcriptional programs of both CTC subtypes included cell survival maintenance, cell proliferation, and migration pathways. ABCB5-enriched CTCs were specifically characterised …

Endo-Β-1,3-Glucanase (Gh16 Family) From Trichoderma Harzianum Participates In Cell Wall Biogenesis But Is Not Essential For Antagonism Against Plant Pathogens, Marcela Suriani Ribeiro, Renato Graciano De Paula, Aline Raquel Voltan, Raphaela Georg De Castro, Cláudia Batista Carraro, Leandro José De Assis, Andrei Stecca Steindorff, Gustavo Henrique Goldman, Roberto Nascimento Silva, Cirano José Ulhoa, Valdirene Neves Monteiro

Peninsula Medical School

Trichoderma species are known for their ability to produce lytic enzymes, such as exoglucanases, endoglucanases, chitinases, and proteases, which play important roles in cell wall degradation of phytopathogens. β-glucanases play crucial roles in the morphogenetic-morphological process during the development and differentiation processes in Trichoderma species, which have β-glucans as the primary components of their cell walls. Despite the importance of glucanases in the mycoparasitism of Trichoderma spp., only a few functional analysis studies have been conducted on glucanases. In the present study, we used a functional genomics approach to investigate the functional role of the gluc31 gene, which encodes an …

Research outputs 2014 to 2021

Background: As the problem of chronic pain grows worldwide, rehabilitation is critical to improved patient well-being. There is thus a need for rehabilitation-focused research. It appears that outcomes are improved when patients perceive the rehabilitation process to be meaningful. However, there is no empirical evidence determining how this would be achieved. An important first step is to identify and describe the concept of meaningfulness as it is used in the chronic pain rehabilitation literature. Objective: This paper reports the findings of a structured concept analysis to define meaningfulness from the patient perspective in chronic pain rehabilitation. Methodology: In consultation with …

Mixing Genetically And Morphologically Distinct Populations In Translocations: Asymmetrical Introgression In A Newly Established Population Of The Boodie (Bettongia Lesueur), Rujiporn Thavornkanlapachai, Harriet R. Mills, Kym Ottewell, Judy Dunlop, Colleen Sims, Keith Morris, Felicity Donaldson, W. Jason Kennington

Research outputs 2014 to 2021

The use of multiple source populations provides a way to maximise genetic variation and reduce the impacts of inbreeding depression in newly established translocated populations. However, there is a risk that individuals from different source populations will not interbreed, leading to population structure and smaller effective population sizes than expected. Here, we investigate the genetic consequences of mixing two isolated, morphologically distinct island populations of boodies (Bettongia lesueur) in a translocation to mainland Australia over three generations. Using 18 microsatellite loci and the mitochondrial D-loop region, we monitored the released animals and their offspring between 2010 and 2013. Despite high …

Associations Of Ambivalent Leadership With Distress And Cortisol Secretion, Wendy C. Birmingham, Raphael M. Herr, Frenk Van Harreveld, Bert N. Uchino, Adrian Loerbroks, Joachim E. Fischer, Jos A. Bosch

Faculty Publications

Ambivalent social ties, i.e., whereby a relationship is evaluated simultaneously in positive and negative terms, are a potential source of distress and can perturb health-relevant biological functions. Social interactions at the workplace, in particular with supervisors, are often described in ambivalent terms, but the psychological and psychobiological impact of such interactions has received little scientific attention. The current study examined associations between ambivalent attitudes towards one’s supervisor, perceived distress (general and work-related), and diurnal dynamics of the stress hormone cortisol. 613 employees evaluated their supervisor in terms of positive and negative behaviors, which was combined into an ambivalent index. Higher …

The Mediation Of Affect On Imagery Use And Self-Efficacy In Collegiate Athletes, Michelle Wirbiezcas

College of Graduate Studies: Theses & Dissertations

In the sports domain, research has become an essential part of how we understand the psychological factors that play a key role in maximizing performance. Previous research has suggested that an individual’s performance can be highly influenced by the psychological variable of self-efficacy (e.g., Bandura, 1997; Calmels & Fournier, 2001). Self-efficacy has been used to describe individuals’ perceived capability of achieving a certain level of performance in the domain of sport (Feltz, 1998). Previous research has also demonstrated that the tendency of athletes to interpret their imagery as either facilitative or debilitative affects specific constructs known to enhance or impede …

The Impact Of Stress On Resilience: Examining The Moderated Effects Of A Savoring Intervention, Hannah L. Newman

College of Graduate Studies: Theses & Dissertations

Resilience is characterized by the ability to bounce back from stress (Bonanno, 2004; Ong et al., 2006; Smith et al., 2008). Research suggests resilience is a personal resource that helps individuals effectively cope with stress and provides protection from negative outcomes (Loh, Schutte, & Thorsteinsson, 2013). Exposure to stress is a prerequisite to building resilience across many different contexts (Graber et al., 2015; Hennessey & Levine, 1979; Rutter, 2006). Interestingly, a high accumulation of stress detracts from an individual’s abilities to build resilience (Ong et al., 2006; Tuguade & Frederickson, 2007). However, it is unknown what types of interventions explicitly …

Ego Depletion: Buffering Through Touch, Victoria E. Forgea

College of Graduate Studies: Theses & Dissertations

Ego depletion theory states that self-control is tied to a limited resource and diminishes after repeated exertions; consequently, the current study sought to examine how to replenish self-control through touch. Due to the positive outcomes of touch, we expected touch to allow participants to persist longer on a geometric tracing puzzle task after becoming ego depleted. The current study implemented measures widely used in the ego depletion literature, and the experimenter implemented two brief touches to examine the effects of touch in the domain of self-control. We found that participants who received touch persisted significantly longer on the geometric tracing …

Player-Coach Perceptions Of Internal Load, Exertion, And Recovery In Collegiate Male Soccer Players, Michelle L. Eisenman

College of Graduate Studies: Theses & Dissertations

Periodization of athlete training load to improve performance and maximize recovery, while reducing injuries and overtraining, is essential in team sports. Understanding internal load responses and monitoring athlete exertion and recovery can help coaches during a competitive season. Recovery Status (PRS) and Rating of Perceived Exertion (RPE) are two subjective scales used to help quantify training load and recovery. These scales are more useful if there is an agreement between coaches (C) and players (P) assessment of intensity and recovery. PURPOSE: To assess subjective measures (PRS and RPE scores) from P and C during a 13-week competitive soccer season. Furthermore, …

Thermal And Low Oxygen Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), Daniel A. Lleras

College of Graduate Studies: Theses & Dissertations

Climate change projections estimate a 2-3°C increase in water temperatures by the end of the century. The amount of habitat with suitable temperature and oxygen concentration for aquatic organisms will also be reduced. Striped bass (Morone saxatilis) inhabiting the rivers in Southeastern Georgia make an interesting study system as they do not participate in summer coastal migrations typical of their northern conspecifics. Instead, fish in this southern population remain in freshwater environments that experience warming and decreases in dissolved oxygen. The present study aims to determine the thermal and low oxygen tolerance of juvenile striped bass collected from …

Using The Theory Of Reasoned Action To Analyze African American College Students Intentions To Participate In Bio Banking Research, Bethrand O. Ugwu

College of Graduate Studies: Theses & Dissertations

The proliferation of biobanks has created new opportunities for researchers to conduct cutting-edge research that was not possible a decade ago. The results of early studies using biospecimens in cancer research have been encouraging. However, researchers are concerned about the applicability of the new knowledge that is being produced to racially diverse subgroups because African American (AA) participation in biobanking research is low. The current study assessed how AA college students’ attitudes and social norms influenced their intentions to participate in biobanking research. This research was guided by Ajzen and Fishbein’s Theory of Reasoned Action as the analytic lens. Methods: …

Development Of An Impedance-Controlled Hot Snare Polypectomy Device To Minimize Tissue Damage, Curtislee Thornton

College of Graduate Studies: Theses & Dissertations

This study explores the ability to measure the changing impedance, ex vivo, of a porcine colon sample while undergoing a high-frequency alternating current from an Olympus PSD-30 electrosurgical unit and stop the applied current before excessive tissue damage ensues. The causes of the thermal damage are first examined, followed by the construction and testing of the impedance-controlled feedback device. Perforation was observed to occur when the impedance of the tissue sample increased by 25% or more. Using this information, the device was tested for five power settings ranging from 10W-50W. In each trial, the feedback device stopped the applied current …

An Examination Of The Effects Of Guided Imagery Theme On Stress And Mood Following An Ego-Depletion Task, Thomas H. Hutchison

College of Graduate Studies: Theses & Dissertations

People experience stress on a daily basis. If not properly managed, stress can lead to disturbances in cognitive functioning, mood-related problems, obesity, and heart disease. Guided imagery has been shown to be an effective technique to help people recover from stress. The literature on guided imagery, however, does not take the theme of the guided imagery script into account. Additionally, there are gaps in the research regarding any interaction between rurality and mood, stress, and guided imagery. A repeated measures MANOVA was conducted to test the main aim of this study; that is, to determine if theme of guided imagery …

Behavioral And Molecular Analysis Of Memory In The Dwarf Cuttlefish, Jessica M. Bowers

College of Graduate Studies: Theses & Dissertations

Complex memory has evolved because it benefits animals in all areas of life, such as remembering the location of food or conspecifics, and learning to avoid dangerous stimuli. Advances made by studying relatively simple nervous systems, such as those in gastropod mollusks, can now be used to study mechanisms of memory in more complex systems. Cephalopods offer a unique opportunity to study the mechanisms of memory in a complex invertebrates. The dwarf cuttlefish, Sepia bandensis, is a useful memory model because its fast development and small size allows it to be reared and tested in large numbers. However, primary literature …
