Template-Based C8-Scorpion: A Protein 8 State Secondary Structure Prediction Method Using Structural Information And Context-Based Features, Ashraf Yaseen, Yaohang Li

Computer Science Faculty Publications

Background: Secondary structures prediction of proteins is important to many protein structure modeling applications. Correct prediction of secondary structures can significantly reduce the degrees of freedom in protein tertiary structure modeling and therefore reduces the difficulty of obtaining high resolution 3D models.

Methods: In this work, we investigate a template-based approach to enhance 8-state secondary structure prediction accuracy. We construct structural templates from known protein structures with certain sequence similarity. The structural templates are then incorporated as features with sequence and evolutionary information to train two-stage neural networks. In case of structural templates absence, heuristic structural information is incorporated instead. …

Toward A Real Time Multi-Tissue Adaptive Physics Based Non-Rigid Registration Framework For Brain Tumor Resection, Fotis Drakopoulos, Panagiotis Foteinos, Yixun Liu, Nikos Chrisochoides

Computer Science Faculty Publications

This paper presents an adaptive non-rigid registration method for aligning pre-operative MRI with intra-operative MRI (iMRI) to compensate for brain deformation during brain tumor resection. This method extends a successful existing Physics-Based Non-Rigid Registration (PBNRR) technique implemented in ITKv4.5. The new method relies on a parallel adaptive heterogeneous biomechanical Finite Element (FE) model for tissue/tumor removal depicted in the iMRI. In contrast the existing PBNRR in ITK relies on homogeneous static FE model designed for brain shift only (i.e., it is not designed to handle brain tumor resection). As a result, the new method (1) accurately captures the intra-operative deformations …

Post-School Adult Life For Young People With Down Syndrome, Kitty Rose Foley

Theses: Doctorates and Masters

Down syndrome is a chromosomal birth disorder affecting one in 650 to 1000 live births in Western Australia. The life expectancy for people with Down syndrome has increased dramatically over the past two generations leading to these young people having changing needs in terms of social, economic and personal life. Encompassed within this, is the successful transition from school to post-school, a time of upheaval, stress and important decisions for young people with intellectual disabilities. The International classification of functioning, disability and health (ICF) is a world renowned framework which provides a scientific basis and standardised language for describing and …

The Australian Football League And The Closet, Andrew Douglas

Theses: Doctorates and Masters

This thesis examines the complete absence of openly gay males from the ranksof the professional players in the Australian Football League (AFL). It seeks to explain this absence in the context of the modern gay rights movement. incontemporary Australian society. It compares and contrasts the effects of thismovement on both the AFL and other mainstream Australian social institutions.

Over more than four decades, the gay rights movement has effected a number of social changes. These changes include both specific legal reforms and more general trends such as the increasing social visibility of gay men across a range of mainstream institutions …

The Effect Of A Professional Development Model On Teachers' Knowledge, Beliefs And Instructional Practices In Teaching Early Reading, Gemma Scarparolo

Theses: Doctorates and Masters

The release of several major evidence-based reports and reviews worldwmilcatide in the last 15 years on teaching reading, have reported that one of the most effective ways to teach the necessary decoding skills for beginning readers is to include and teach phonological awareness and phonics in an explicit, direct and systematic manner. To achieve this, researchers and educators have placed an emphasis on the key role that evidence-based professional development plays in providing teachers with the necessary knowledge, understandings and instructional skills to be able to teach these skills effectively to beginning readers. Professional development has three aims: to change …

Acute Physiological Effects And Perceived Enjoyment Of A Single Bout Of Aerobic Interval And Continuous Moderate-Intensity Cycling In Overweight And Obese Individuals, Fujie Koh

Theses: Doctorates and Masters

Aerobic interval training, a form of high intensity interval training, is commonly prescribed to both the general and clinical populations. However, the acute physiological effects from a single bout of aerobic interval session are not fully understood. In training studies, these acute physiological effects may confound actual training adaptations when they occur following the final training session [1]. Furthermore, while recreationally active men perceived aerobic interval training to be more enjoyable than continuous moderate-intensity exercise [2], the preference of overweight and obese individuals has not been extensively researched. Since overweight and obese individuals tend to have lower exercise tolerance, it …

Website Accessibility In Australia And The National Transition Strategy: Outcomes And Findings, Vivienne Conway

Theses: Doctorates and Masters

In the most recent statistics, published by the Australian Bureau of Statistics in 2012, it was reported that slightly under one in five people stated they had a disability. A further twenty-one percent of the population (4.7 million people) reported that they had a long-term health condition that did not restrict their everyday activities. This total group of people who suffer either a disability or a long-term health condition numbers 8.9 million people, or over thirty-nine percent of the Australian population. Of the people reporting a disability, 3.7 million or eighty-eight percent of that group experienced limitations in the activities …

A Mixed Methods Obesity Prevention Intervention For Australian Children Aged 6-12 Years: Influence Of Parents Misperceptions About Food And Exercise On The Efficacy Of Educational Obesity Simulations, Claire Ellen Roockley

Theses: Doctorates and Masters

Increasing numbers of Australian children are being classified as overweight or obese. Given the health complications associated with excess weight, interventions to prevent children becoming overweight are crucial. Despite literature showing that parents shape their children’s food and exercise habits, no child obesity prevention programs have directly targeted parents. Moreover, although fear appeals have been used across several health promotion areas to change attitudes and behaviours, they have not been incorporated into an obesity preventive program. This study addressed these gaps by testing whether fear-based obesity simulations, targeted at parents as a tool for preventing childhood obesity, was more effective …

Cultures Of Practice Within Design: An Exploration Of The Differences And Similarities Between Photography And Painting As Representational Practices, Alun John Price

Theses: Doctorates and Masters

Contemporary designers and photographers face many challenges as the profession rapidly develops. This is especially the case in in the Western Australian context. A review into the recent history of the Western Australian design profession is evidence that designers and photographers are consistently shifting between commercial and self-expressive practice. However, the urge to keep up with technological advancement has masked conscious development of this shift, which is a key to self-realisation and improvement for a designer and photographer. This lack of conscious questioning limits holistic development in design practice. This research reflects on myself as a designer developing a response …

The Distinct Contributions Of Affective Distress And Personality To Memory Complaints Made In Older Adulthood, Matthew Robert Merema

Theses: Doctorates and Masters

Whilst a substantial amount of research has investigated the role of affective distress and features of personality in memory complaints made by older adults, little effort has been directed towards understanding their distinct contributions to complaints. Given considerable overlap between affective distress and features of personality, such evidence is necessary to inform theoretical frameworks pertaining to memory complaints and clarify results from other empirical studies examining these concepts. Consequently, the current study examined symptoms of depression and anxiety as predictors of memory complaints within the context of features of personality and other relevant contextual variables (i.e., age, gender, education, premorbid …

Education And Training Of Specialist Sexual Offence Investigators In Victoria, Australia From 2009 To 2011, Jennifer Anne Turnley

Theses: Doctorates and Masters

The topic of training specifically designed for investigators of sexual offences has received little attention from academic researchers to date. Previous studies have not described training provided to police investigators of sexual offences in Australia. This thesis developed Turnley’s Framework for the Examination of Police Training in Sexual Assault Investigation, to examine and describe a Sexual Offences and Child Abuse Investigative Teams (SOCIT) Course, provided to Victorian Police from 2009 to 2011. This entailed triangulation of findings from non-participant observations of one SOCIT Course, with quantitative and qualitative data sourced though an in-depth interview with course trainers; feedback sheets voluntarily …

Meaningful Encounters: Creating A Multi-Method Site For Interacting With Nonhuman Life Through Bioarts Praxis, Donna Franklin

Theses: Doctorates and Masters

This research advocates a multi-method approach to bioarts praxis, reflexively and critically questioning the contemporary contexts that frame our engagement with nonhuman life. In doing so, the research aims to generate further community engagement with nonhuman life and the environment, and engender critical discourse on the implications of developing biotechnologies.

Hegemonic institutions influence the way culture is produced and how information is constructed and understood. Habermas (1987) suggests that these institutions will inevitably influence the individual’s lifeworld as they shape lived experience through the process of systemic colonisation. I assert that this process also shapes how individuals engage with or …

Jean-Luc Godard's Breathless: The Revelation Of Filmmaking As Cinephilia, Alexandra Proud

Theses : Honours

Auteur, Jean-Luc Godard directed his first feature film Breathless (A bout de soufflé) in 1959 after a decade of working as a film critic for the contentious journal, Cahiers du Cinema. Central to my thesis is the assertion that Breathless is contentious in critical dimension to Godard’s literary criticism. It takes a certain breed of individual with a genuine passion for the state of the French film industry to sustain a politically charged critique of cinema from literary film criticism to filmmaking. The breed of individual is known as a cinephile – an avid moviegoer who may also engage …

Detection And Control Of Small Civilian Uavs, Matthew Peacock

Theses : Honours

With the increasing proliferation of small civilian Unmanned Aerial Vehicles (UAVs), the threat to critical infrastructure (CI) security and privacy is now widely recognised and must be addressed. These devices are easily available at a low cost, with their usage largely unrestricted allowing users to have no accountability. Further, current implementations of UAVs have little to no security measures applied to their control interfaces. To combat the threat raised by small UAVs, being aware of their presence is required, a task that can be challenging and often requires customised hardware.

This thesis aimed to address the threats posed by the …

Improving Pre-Hospital Care At Mass Gathering Events: Applying Military Intelligence Methodology To The St John Ambulance Wa Event Health Operations, Alan James Davies

Theses : Honours

With the growth of the mass gathering event domain and its ever constant place within the contemporary Australian lifestyle, the number of patrons who attend these events that require medical assistance rises (Zeitz et al., 2007, p. 23; Zeitz, Zeitz, & Arbon, 2005, p. 164; Zeitz, Zeitz, & Kadow-Griffin, 2012). This increased demand and inherited risk to the event organiser, the patrons attending and the pre-hospital care or first aid provider creates a need for the investigation into enhancements to the medical care operations at these events. The provision of pre-hospital care at mass gathering events in Western Australia is …

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?” …

Eighteenth Century Techniques Of Classical Improvisation On The Violin: Pedagogy, Practice And Decline, Flavia Claudia Todea

Theses : Honours

The art of improvisation flourished in both instrumental and vocal music during the late seventeenth and throughout the eighteenth centuries. The violin techniques of improvisation taught in the eighteenth century (such as ornamentation of melody, decoration of fermatas, extemporization of cadenzas and creation of preludes) formed an integral part of instrumental pedagogy and performance practice at the time, which then declined significantly from the early nineteenth century onwards. It seems that this practice of improvisation has been neglected and its principles almost forgotten in the world of classical Western music today. This paper makes an argument for the re-introduction of …

On The Security Of Auditing Mechanisms For Secure Cloud Storage, Yong Yu, Lei Niu, Guomin Yang, Yi Mu, Willy Susilo

Research Collection School Of Computing and Information Systems

Cloud computing is a novel computing model that enables convenient and on-demand access to a shared pool of configurable computing resources. Auditing services are highly essential to make sure that the data is correctly hosted in the cloud. In this paper, we investigate the active adversary attacks in three auditing mechanisms for shared data in the cloud, including two identity privacy-preserving auditing mechanisms called Oruta and Knox, and a distributed storage integrity auditing mechanism.We show that these schemes become insecure when active adversaries are involved in the cloud storage. Specifically, an active adversary can arbitrarily alter the cloud data without …

Specification Testing For Transformation Models, Arthur Lewbel, Xun Lu, Liangjun Su

Research Collection School Of Economics

Consider a nonseparable model Y=R(X,U) where Y and X are observed, while U is unobserved and conditionally independent of X. This paper provides the first nonparametric test of whether R takes the form of a transformation model, meaning that Y is monotonic in the sum of a function of X plus a function of U. Transformation models of this form are commonly assumed in economics, including, e.g., standard specifications of duration models and hedonic pricing models. Our test statistic is asymptotically normal under local alternatives and consistent against nonparametric alternatives. Monte Carlo experiments show that our test performs well in …

Complexity Of The Soundness Problem Of Workflow Nets, Guan Jun Liu, Jun Sun, Yang Liu, Jin Song Dong

Research Collection School Of Computing and Information Systems

Classical workflow nets (WF-nets for short) are an important subclass of Petri nets that are widely used to model and analyze workflow systems. Soundness is a crucial property of workflow systems and guarantees that these systems are deadlock-free and bounded. Aalst et al. proved that the soundness problem is decidable for WF-nets and can be polynomially solvable for free-choice WF-nets. This paper proves that the soundness problem is PSPACE-hard for WF-nets. Furthermore, it is proven that the soundness problem is PSPACE-complete for bounded WF-nets. Based on the above conclusion, it is derived that the soundness problem is also PSPACE-complete for …

Theses And Dissertations At The University Of The West Indies, St. Augustine: A Liaison Librarian’S Input., Rabia Ramlogan Mrs

Library Philosophy and Practice (e-journal)

Academic libraries’ traditional and central role is largely supporting the teaching, learning and research objectives of their parent institutions. To this end, many libraries utilize liaison librarian programs, one type of an academic library service model to make connections with faculty, students and researchers.

This paper, in the context of academic library services and academic research output, looks at a unique service, namely that of thesis checking, provided by liaison librarians at the Alma Jordan Library (AJL), the University of the West Indies (UWI), St. Augustine (STA) Campus.

Faculty are the leading researchers on campus but graduate students also contribute …

Collection Development In The Humanities And Social Sciences In A Transitional Age: Deaccession Of Print Items, David E. Woolwine

Library Philosophy and Practice (e-journal)

A literature review of user preferences, research habits and needs, and citation studies are used to argue that deaccession of print titles in the humanities and social sciences in academic libraries should occur in a conservative fashion as libraries transition to greater digital holdings. The issue of retention of translations is given special emphasis. The centrality of engaged research for undergraduate education makes the retention, at present, of both a rich print and digital collection necessary as the distinction between a collection geared toward faculty research and one for undergraduate research becomes less important.

The Use Of Social Networking Sites Among The Undergraduate Students Of University Of Nigeria, Nsukka, Helen N. Eke Miss, Charles Obiora Omekwu Prof, Jennifer Nneka Odoh Miss

Library Philosophy and Practice (e-journal)

This study was carried out to investigate the use of social networking sites among the undergraduate students of university of Nigeria Nsukka. In the context of today’s electronic media, social networking sites have come to mean individuals, using the Internet and web application to communicate in previously impossible ways. This is largely the result of a culture-wide paradigm shift in the uses and possibilities of the internet itself. The objectives of the study are to ascertain the various categories of social networking sites used by UNN Undergraduates, to examine the extent of usage of social networking sites by UNN Undergraduates, …

Molecular Markers Reveal Narrow Genetic Base And Culturing-Associated Genetic Drift In Teretrius Nigrescens Lewis Populations Released For The Biological Control Of The Larger Grain Borer In Africa, B. A. Omondi, J. Van Den Berg, D. Masiga, F. Schulthess

All Peer-Reviewed Publications

In biological control, successful establishment of a natural enemy species depends on its adaptability in the introduced range including its ability to re-establish desired ecological interactions with the pest. These are affected by genetic parameters hitherto largely unresolved in biological control. The larger grain borer (LGB), Prostephanus truncatus, an invasive species from meso-America, is the most important post-harvest pest of maize in Africa. We studied the genetic structure of Teretrius nigrescens, a predatory beetle previously released for the control of the pest in Africa, to test the hypothesis that establishment patterns were a result of ecotype-environment mismatch and to follow …

Spatial Analysis Of Human-Induced Vegetation Productivity Decline Over Eastern Africa Using A Decade (2001-2011) Of Medium Resolution Modis Time-Series Data, Tobias Landmann, Olena Dubovyk

All Peer-Reviewed Publications

Climate variation and land transformations related to exploitative land uses are among the main drivers of vegetation productivity decline and ongoing land degradation in East Africa. We combined analysis of vegetation trends and cumulative rain use efficiency differences (CRD), calculated from 250-m MODISNDVI time-series data, to map vegetation productivity loss over eastern Africa between 2001 and 2011.The CRD index values were furthermore used to discern areas of particular severe vegetation productivity loss over the observation period. Monthly 25-km Tropical Rainfall Measuring Mission (TRMM) datametrics were used to mask areas of rainfall declines not related to human-induced land productivity loss. To …

Systematics And Biogeography Of The Australian Burrowing Freshwater Crayfish Genus Engaewa Riekk (Decapoda: Parastacidae), Quinton Burnham

Theses: Doctorates and Masters

The overall aim of this study was to explore the systematics and biogeographic patterns of the freshwater crayfish genus Engaewa Riek, a strongly burrowing freshwater crayfish restricted to the coastal corner of south-western Australia (SWA). The genus Engaewa is a Gondwanan relict with great potential as a marker of historical processes, due to its high habitat specificity and low dispersal ability. This study comprises an extensive taxonomic and phylogenetic revision of the genus Engaewa (using both molecular and morphological data), a detailed study of its distribution and uses the knowledge gained to explore biogeographic patterns in the biodiversity hotspot of …

Neuromuscular Factors Affecting Stretch-Induced Torque Loss, Gabriel Siqueira Trajano

Theses: Doctorates and Masters

The mechanisms underpinning the immediate torque loss induced by acute, static muscle stretching are still not clear. The current research was designed to examine the neuromuscular factors influencing this torque loss. In Study 1, the contributions of central versus peripheral factors to the stretch-induced torque loss were investigated. Measures of central drive, including the EMG amplitude normalised to the muscle compound action potential amplitude (EMG:M), percent voluntary activation (%VA) and first volitional wave amplitude (V:M), and measures of peripheral function, including the twitch peak torque and 20:80 Hz tetanic torque ratio were made before, and immediately and 15 min after …

On Empirical Validation Of Compactness Measures For Electoral Redistricting And Its Significance For Application Of Models In The Social Sciences, Christine Chou, Steven O. Kimbrough, Frederic H. Murphy, John Sullivan-Fedock, C. Jason Woodard

Research Collection School Of Computing and Information Systems

Use of optimization models in science and policy applications is often problematic because the best available models are very inaccurate representations of the originating problems. Such is the case with electoral districting models, for which there exist no generally accepted measures of compactness, in spite of many proposals and much analytical study. This article reports on an experimental investigation of subjective judgments of compactness for electoral districts. The experiment draws on a unique database of 116 distinct, legally valid districting plans for the Philadelphia City Council, discovered with evolutionary computation. Subjects in the experiment displayed, in the aggregate, remarkable agreement …

The Controversy Over Citations To Foreign Authorities In American Constitutional Adjudication And The Conflict Of Judicial Philosophies: A Reply To Professor Glendon, Michel Rosenfeld

Articles

The controversy over U.S. Supreme Court justices citing foreign authorities in constitutional cases reflects a deeper ideological divide between restrictive and expansive judicial philosophies. This debate, evident in cases like Lawrence v. Texas and Roper v. Simmons, transcends traditional labels like originalism or political ideology, focusing instead on whether judges should defer to majoritarian decisionmaking or actively shape evolving rights. The article argues that the furor over foreign citations will diminish once the broader philosophical clash over judicial interpretation is resolved, as differences over foreign authorities are secondary to this central divide.
