Owning The Problem: Media Portrayals Of Overweight Dogs And The Shared Determinants Of The Health Of Human And Companion Animal Populations, Christopher J. Degeling, Melanie Rock

Faculty of Social Sciences - Papers (Archive)

Weight-related health problems have become a common topic in Western mass media. News coverage has also extended to overweight pets, particularly since 2003 when the US National Academy of Sciences announced that obesity was also afflicting co-habiting companion animals in record numbers. To characterize and track views in popular circulation on causes, consequences, and responsibilities vis-à-vis weight gain and obesity, in pets as well as in people, this study examines portrayals of overweight dogs that appeared from 2000 through 2009 in British, American, and Australian mass media. The ethnographic content analysis drew inspiration from the literature in population health, animal-human …

Ethical Practice In Learning Through Participation: Showcasing And Evaluating The Pace Ethical Practice Module, Michaela Baker, Alison Beale, Laura Ann Hammersley, Kate Lloyd, Anne-Louise Semple, Karolyn L. White

Faculty of Social Sciences - Papers (Archive)

In 2008, Macquarie University introduced the Participation and Community Engagement (PACE) initiative, which embeds units in the undergraduate curriculum that involve learning through participation, including service learning and work-integrated learning (WIL), that is mutually beneficial to the student, the University and the partner organisation. Ethical practice is thus an integral part of this initiative. However, the issue of ethical practice in these approaches to learning has not been comprehensively addressed (Peterson et al, 2007) with research ethics in undergraduate curricula also warranting further examination and integration (Crabtree, 2008; Tryon et al., 2008). To support both students and staff at Macquarie …

High Incidence Of Nasopharyngeal Cancer: Similarity For 60% Of Mitochondrial Dna Signatures Between The Bidayuhs Of Borneo And The Bai-Yue Of Southern China, Joseph Tien Seng Wee, Tam C. Ha, Susan Loong, Chao-Nan Qian

Faculty of Social Sciences - Papers (Archive)

Populations in Southern China (Bai-yue) and Borneo (Bidayuh) with high incidence of nasopharyngeal cancer(NPC) share similar mitochondrial DNA signatures, supporting the hypothesis that these two populations may share the same genetic predisposition for NPC, which may have first appeared in a common ancestral reference population before the sea levels rose after the last ice age.

A Country That Makes Things: Rethinking And Broadening Manufacturing, Christopher R. Gibson

Faculty of Social Sciences - Papers (Archive)

The announcement in August 2011 that BlueScope Steel were about to close one of its Port Kembla blast furnaces and cease steel exports quickly spurred public debate in Australia, not just about steel but about the very future of manufacturing in Australia. Australian Workers' Union national secretary Paul Howes thus suggested: 'The question the Australian community needs to ask itself - is do we want to be a country that still makes things? Do we want to value-­‐‑add to our natural resources, or do we want to become just one big sandpit for China and a tourism resort for North …

Exploring Flow Occurrence In Elite Golf, Christian F. Swann, Richard J. Keegan, David Piggott, Lee Crust, Mark F. Smith

Faculty of Social Sciences - Papers (Archive)

Research on flow (Csikszentmihalyi, 1975) has traditionally focused on reactive, externally-paced sports (e.g., tennis) without exploring those that are self-paced and stopstart in nature. This study investigated the occurrence of flow in a sample of thirteen elite golfers by conducting semi-structured interviews discussing: (i) their experiences of flow, (ii) factors that influenced flow occurrence, and (iii) the controllability of these experiences. Results shared similarity with existing research in terms of the majority of influencing factors reported, including motivation, preparation, focus, psychological state, environmental and situational conditions, and arousal, and that flow was reported to be at least potentially controllable. Golf-specific …

Sports Sponsorship And Kids' Health: Who Are The Real Winners?, Rona Macniven, Bridget Kelly

Faculty of Social Sciences - Papers (Archive)

Over the weekend, Australian children and their parents witnessed some of the country's finest sportsmen display feats of strength, skill and endurance in the Australian Football League (AFL) and National Rugby League (NRL) grand finals. I'm sure many young people would have been inspired to emulate the actions and successes of their heroes.

What spectators and viewers would also have seen was the paradoxical promotion of Carlton breweries and McDonalds in commercial advertisements during the games. The websites of the NRL, AFL reveal a similar picture of sponsorship and marketing by unhealthy food and drink companies such as Coca-Cola and …

'If I Buy The Kellogg's Then He Should [Buy] The Milk': Young Women's Perspectives On Relationship Dynamics, Gender Power And Hiv Risk In Johannesburg, South Africa, Audrey Pettifor, Catherine L. Mac Phail, Althea Anderson, Suzanne Maman

Faculty of Social Sciences - Papers (Archive)

Ideals of masculinity and femininity may limit South African women's decision making power in relationships and increase their risk of HIV infection. We conducted 30 in-depth interviews with 18-24-year-old women in inner-city Johannesburg with the aim of understanding young women's expectations of intimate relationships with men, their perceptions of gender and power and how this influences HIV risk. We found that the majority of young women reported expectations of power in relationships that conform to a model of femininity marked by financial independence, freedom to make decisions, including over sexuality, and equality (resistant femininity). The majority of young women, however, …

Critical Geographies With The State: The Problem Of Social Vulnerability And The Politics Of Engaged Research, Pauline M. Mcguirk, Phillip O'Neill

Faculty of Social Sciences - Papers (Archive)

State interventions to govern social vulnerability highlight the complexity of contemporary states, marked by neoliberal agenda but also by progressive interventions and the desire for effectiveness. This paper draws on collaborative research with government agencies on social vulnerability in the Hunter region to assess the desirability of undertaking critical geographies with the state. We see states as contested terrains invested with the institutional capacity to mobilise diverse political projects. We argue that critical research in partnership with states is possible, as are mobilisations of the agency of state institutions to promote progressive policy development. The paper explores how we might …

Las Influencias Del Hogar, El Pre-Escolar Y La Escuela Primaria Sobre El Rendimiento Educativo A Los Once Anos Del Nino, Edward Melhuish, Pam Sammons, Kathy Sylva, Iram Siraj-Blatchford, Brenda Taggart

Faculty of Social Sciences - Papers (Archive)

This paper examines the benefits of Pre-school centre experience in disadvantaged children's school readiness, educational achievements and social adjustment. In this article, we describe findings from a large-scale longitudinal study in England that provides evidence on the contribution of home, pre-school and primary school to children's development, a unique evidence for a sample that is close to nationally representative rather than for disadvantaged groups only and thus provides stronger evidence relevant to the issue of the benefits that might accrue generally from universal preschool provision. Data from this study can be used to look at the relative benefits accruing from …

A Critical Appraisal Of Responses To Maori Offending, Juan M. Tauri, Robert Webb

Faculty of Social Sciences - Papers (Archive)

This article critically analyses the role that criminological theory and specific policy formulations of culture play in New Zealand's state response to Māori crime. We begin by charting policy responses to the "Māori problem" during the 1980s to the 2000s, with a particular focus on policies and interventions based on theorising that Māori offending is attributable to loss of cultural identity, through to the current preference for risk factor and criminogenic needs approaches. The second part of the article critiques strategies employed by administrative criminologists who, in partnership with the policy sector, attempt to elevate their own epistemological constructions of …

Robust Sampled-Data Control Of Structures Subject To Parameter Uncertainties And Actuator Saturation, Haiping Du, Nong Zhang, Bijan Samali, Fazel Naghdy

Faculty of Engineering and Information Sciences - Papers: Part A

"This paper presents a robust sampled-data controller design approach for vibration attenuation of civil structures considering parameter uncertainties and actuator saturation. The parameter uncertainties belong to polytopic form and are assumed to be the variations of the structural stiffness and damping. Regarding the uncertain sampling problem encountered in real world applications, the sampling period designed for the controller is allowed to be variable within a given bound. In order to obtain reduced peak response quantities, the energy-to-peak performance used to describe the peak values of the control output under all possible energy-bounded disturbances is optimised. The robust sampled-data state feedback …

Therefore, this study is an initial effort towards bridging the existing knowledge gap in the literature. Design/methodology: This exploratory research was conducted in one retail supply chain. A multi-method approach combining a longitudinal real-life case study and a methodology integrating several steps, including a “Living Laboratory” strategy was used and involved all members of a product line to analyze in terms of their contributing activities and their interface with …

Rietveld Analysis Of The Effect Of Annealing Atmosphere On Phase Evolution Of Nanocrystalline Tio 2 Powders, M Salari, M Rezaee, A T. Chidembo, Konstantin Konstantinov, Hua-Kun Liu

Faculty of Engineering and Information Sciences - Papers: Part A

The struclUral evolution of nanocrystaUine Ti02 was studied by X-ray diffraction (XRD) and the Rietveld refinement method (RRM). Ti02 powders were prepared by the sol-gel technique. Post annealing of as·synthesized powders in the temperature range from 500°C to 600 °C under air and argon atmospheres led to the formation of Ti02 nanoparticles with mean crystallite size in the range of 37-165 nm. based on the Rietveld refinement results. It was found that the phase structure, composition, and crystallite size of the resulting particles were dependent on not only the annealing temperature, but also the annealing atmosphere. Rietveld refinement of the …

Flicker Propagation Analysis In Distribution Networks With Embedded Generation, D Perera, L Meegahapola, S Perera, P Ciufo

Faculty of Engineering and Information Sciences - Papers: Part A

Embedded generators such as wind generators can produce observable voltage fluctuations during variable wind conditions hence flicker. The flicker produced by such intermittent and fluctuating generating sources can propagate to other parts of the distribution network while creating power quality issues in distribution feeders. This study presents a flicker emission analysis for a doubly-fed induction generator (DFIG) based wind farm and investigate the pertinent factors which influence flicker propagation and attenuation in distribution feeders. Study has shown that voltage fluctuations are significantly influenced by the attenuation characteristics of various load types (i.e. constant power, impedance and current loads) connected to …

Evolution Of Internal Crack In Bcc Fe Under Compressive Loading, Dongbin Wei, Zhengyi Jiang, Jingtao Han

Faculty of Engineering and Information Sciences - Papers: Part A

A molecular dynamics model has been developed to investigate the evolution of the internal crack of nano scale during heating or compressive loading in BCC Fe. The initial configuration does not contain any pre-existing dislocations. In the case of heating, temperature shows a significant effect on crack evolution and the critical temperature at which the crack healing becomes possible is 673 K. In the case of compressive loading, the crack can be healed at 40 K at a load- ing rate 0.025 × 1018 Pa·m1/2/s in 6 × 10−12 s. The diffusion of Fe atoms into the crack area results …

A Methodology For Bridge Condition Evaluation, Maria Rashidi, Peter Gibson

Faculty of Engineering and Information Sciences - Papers: Part A

Due to the substantial role of bridges in transportation networks and in accordance with the limited funding for bridge management, remediation strategies have to be prioritised. A conservative bridge assessment will result in unnecessary actions, such as costly bridge strengthening or repairs. On the other hand, any bridge maintenance negligence and delayed actions may lead to heavy future costs or degraded assets. The accuracy of decisions developed by any manager or bridge engineer relies on the accuracy of the bridge condition assessment which emanates from visual inspection. Many bridge rating systems are based on a very subjective procedure and are …

Microdosimetry For Targeted Alpha Therapy Of Cancer, Chen-Yu Huang, Susanna Guatelli, Brad Oborn, Barry J. Allen

Faculty of Engineering and Information Sciences - Papers: Part A

Targeted alpha therapy (TAT) has the advantage of delivering therapeutic doses to individual cancer cells while reducing the dose to normal tissues. TAT applications relate to hematologic malignancies and now extend to solid tumors. Results from several clinical trials have shown efficacy with limited toxicity. However, the dosimetry for the labeled alpha particle is challenging because of the heterogeneous antigen expression among cancer cells and the nature of short-range, high-LET alpha radiation. This paper demonstrates that it is inappropriate to investigate the therapeutic efficacy of TAT bymacrodosimetry. The objective of this work is to review the microdosimetry of TAT as …

Delta Extraction Optimization For View Maintenance In A Limited Collaborative Environment, Zheng Lu, Haijun Liu, Peter Hyland

Faculty of Engineering and Information Sciences - Papers: Part A

This work considers maintaining materialized view in a distributed environment where the collaboration from highly autonomous operational database management systems is limited to granting read only access on a set of selected relational tables. In addition, due to possibly large volumes of remote source data involved in the view maintenance process, and consequently enormous overhead associated with data transfer, efficiency issues must been taken into the consideration. This proposal is based on the observation that usually, there is a large amount of static data in relational tables. It is proposed to use some statistical techniques at data warehouse system to …

Purely Infinite C-Algebras Arising From Crossed Products, Mikael Rordam, Adam Sierakowski

Faculty of Engineering and Information Sciences - Papers: Part A

We study conditions that will ensure that a crossed product of a C-algebra by a discrete exact group is purely infinite (simple or non-simple). We are particularly interested in the case of a discrete non-amenable exact group acting on a commutative C-algebra, where our sufficient conditions can be phrased in terms of paradoxicality of subsets of the spectrum of the abelian C-algebra. As an application of our results we show that every discrete countable non-amenable exact group admits a free amenable minimal action on the Cantor set such that the corresponding crossed product C-algebra is a Kirchberg algebra in the …

Multiuser Diversity With Capture In Ofdma Systems With Clustered Feedback, Hang Li, Qinghua Guo, Licai Fang, Defeng (David) Huang

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we propose a cluster-based feedback protocol for multiuser orthogonal frequency-division multipleaccess (OFDMA) systems, where the capture effect is employed in each cluster to reduce the enormous system overhead induced by polling channel-state information. Then, we analyze the system throughput performance of the proposed feedback protocol. Compared with the full feedback scheme in the literature, numerical simulations show that the proposed protocol with clustered feedback in OFDMA systems achieves higher system throughput by employing the capture effect with limited feedback overhead, when the number of users is reasonably large. Moreover, compared with our previous protocol of Multiuser Diversity …

Fairness And Capacity Analysis Of Opportunistic Feedback Protocol With Proportional Fair Or Maximum Throughput Scheduling, Hang Li, Qinghua Guo, Licai Fang, Defeng (David) Huang

Faculty of Engineering and Information Sciences - Papers: Part A

An opportunistic feedback protocol with maximum throughput (MT) scheduling has been proposed in the literature to achieve multiuser diversity for the downlink transmission of a wireless system, and its system capacity has been analyzed with the assumption that the received signal-to-noise ratios (SNRs) for the users are independent and identically distributed. In this paper, fairness and capacity performances of the opportunistic feedback protocol are analyzed for SNRs with independent but not necessarily identical distributions. In addition to MT scheduling, we also analyze the fairness and capacity performances for proportional fair (PF) scheduling. Compared with MT scheduling, numerical results demonstrate that …

Pleistocene Survivors And Holocene Extinctions: The Giant Rats From Liang Bua (Flores, Indonesia), Elisa Locatelli, Rokhus Awe Due, Gerrit D. Van Den Bergh, Lars W. Van Den Hoek Ostende

Faculty of Science, Medicine and Health - Papers: part A

Excavations at Liang Bua Cave yielded a large amount of micromammal remains, the major part of which are murids, and some can be referred to three different species of giant rats. Whilst Papagomys armandvillei is still living on Flores, the other two species, Papagomys theodorverhoeveni and Spelaeomys florensis went extinct late during the Holocene. In this paper, the fossil record of these species at Liang Bua Cave is discussed. These giant murids are a clear example of insular gigantism, and can be seen as end members of the Island Rule. Opposition against the general applicability of this 'rule' is mainly …

An Inventory Of Landslides Within The Sydney Basin To Aid The Development Of A Refined Susceptibility Zoning, Phillip N. Flentje, David Stirling, Darshika Palamakumbure

Faculty of Engineering and Information Sciences - Papers: Part A

The University of Wollongong GIS-based Landslide Inventory is currently being expanded from its Illawarra centric coverage (664 landslides) to include the 31,000km2 geological extent of the Sydney Basin and ultimately all of New South Wales (hereafter this inventory will be referred to as the NSW LI). In 1998, this inventory stood at 319 sites of instability and in 2010 it had grown to 616 landslides. The population of the Sydney Basin in 2006 was approximately 4.9 million people, representing approximately one quarter of the population of Australia. When this current phase of expansion is completed, the NSW LI will include …
