The Animal Himself
No full textThe title of my thesis, The Animal Himself, and the accompanying quote are taken from the plaque beneath Lincoln's life mask in the National Portrait Gallery. My thesis is predominantly interested in examining the ethics of making art from death and the natural world, and the effects this has on both artist and subject. A section of poems in the thesis are renderings or re-imaginings of my father using a combination of surrealist and autobiographical elements. The poems, with titles like “Father as Chrysalis” or “Father as Taxadermied Jackalope” began as an attempt at understanding my father's death from a variety of vantage points. As the project progressed, the memory of my father began to degrade and was, in some ways, augmented by the art-making process. His memory began to take on a more fractured, mythic quality.This work is embargoed by the author and will not be available until August 2018
Analysis of CDC social control measures using an agent-based simulation of an influenza epidemic in a city
No full textBackground: the transmission of infectious disease amongst the human population is a complex process which requires advanced, often individual-based, models to capture the space-time details observed in reality.Methods: an Individual Space-Time Activity-based Model (ISTAM) was applied to simulate the effectiveness of non-pharmaceutical control measures including: (1) refraining from social activities, (2) school closure and (3) household quarantine, for a hypothetical influenza outbreak in an urban area.Results: amongst the set of control measures tested, refraining from social activities with various compliance levels was relatively ineffective. Household quarantine was very effective, especially for the peak number of cases and total number of cases, with large differences between compliance levels. Household quarantine resulted in a decrease in the peak number of cases from more than 300 to around 158 for a 100% compliance level, a decrease of about 48.7%. The delay in the outbreak peak was about 3 to 17 days. The total number of cases decreased to a range of 3635-5403, that is, 63.7%-94.7% of the baseline value.When coupling control measures, household quarantine together with school closure was the most effective strategy. The resulting space-time distribution of infection in different classes of activity bundles (AB) suggests that the epidemic outbreak is strengthened amongst children and then spread to adults. By sensitivity analysis, this study demonstrated that earlier implementation of control measures leads to greater efficacy. Also, for infectious diseases with larger basic reproduction number, the effectiveness of non-pharmaceutical measures was shown to be limited.Conclusions: simulated results showed that household quarantine was the most effective control measure, while school closure and household quarantine implemented together achieved the greatest benefit. Agent-based models should be applied in the future to evaluate the efficacy of control measures for a range of disease outbreaks in a range of settings given sufficient information about the given case and knowledge about the transmission processes at a fine scal
Reformulating the rj-McMC Algorithm for 3D Inversion of Passive Seismic Data for Near-Surface Characterization
No full textGeophysical subsurface characterization techniques could, due to their non-invasive nature, play a crucial role in the design and subsequent construction of infrastructure in urban & industrial environ- ments. Geo-data specialist company Fugro sees potential in upgrading their current ambient-seismic- noise-tomography workflow, to make use of state-of-the-art inversion schemes with the main goal of increasing the quality and accuracy of the initial-site characterization delivered to clients. In this thesis I explore the feasibility of utilizing the reverse-jump Markov chain Monte Carlo (rj-McMC) algorithm for the inversion of ambient seismic noise for characterization in urban & industrial environments. Specif- ically, testing the potential of scaling down this inversion algorithm to fit in a small scale, near-surface framework. To achieve this, I first carried out analyses to evaluate the appropriate Rayleigh wave frequency range, after which realistic noise hyperparameters, suited for this reduced scale problem, were obtained. Because of the potential exploitation of in-situ borehole measurements, I reformulated the Bayesian prior within the rj-McMC algorithm to implement these constraining shear wave velocity values appropriately. I conducted extensive synthetic experiments to gain insight into the behavior of this adapted algorithm, from which it was concluded that the inherent dynamic discretization partially prevents these constraints from being implemented to their full extent. Nevertheless, promising results lead me to conclude that the use of the rj-McMC algorithm for application in near-surface urban & industrial environments is feasible.Applied Geophysics | IDEA Leagu
The concomitant use of second-generation antipsychotics and long-term antiretroviral therapy may be associated with increased cardiovascular risk
No full textTo study the effect of concurrent use of second-generation antipsychotics (SGAs) on metabolic syndrome (MetS) components conferring increased cardiovascular risk in a sample of human immunodeficiency virus (HIV)-infected adults taking antiretroviral therapy (ART). A retrospective study of participants consecutively recruited at the UCSD HIV Neurobehavioral Research Program examined effects of combined ART and SGAs on body mass index (BMI), nonfasting serum lipids, diabetes mellitus (DM) incidence, and mean arterial pressure (MAP). Metabolic outcome variables and covariates were compared using t-tests, Chi-squared or Fisher's exact tests. Linear and logistic multivariable models explored metabolic outcomes for participants taking (SGA+) or not taking (SGA-) concomitant SGAs, after controlling for demographic and HIV disease- and ART-related covariates. Of 2229 HIV-infected participants, 12% (N=258) were treated with SGAs. In multivariable models adjusted for relevant covariates, the SGA+ group had significantly higher mean triglycerides, significantly higher odds of DM, significantly higher MAPs and marginally higher BMI. The use of SGAs in HIV-infected adults taking ART was independently associated with worse indicators of MetS and cardiovascular risk. Aggressive monitoring for the metabolic complications from concurrent SGA and ART is indicated in all patients receiving these medication combinations. (C) 2014 Elsevier Ireland Ltd.

Trauma-informed services and trauma-specific care for Indigenous Australian children
No full textThis paper examines how childhood trauma experienced by Indigenous children can be overcome by appropriate interventions.IntroductionWhile many Indigenous and non-Indigenous Australian children grow up in safe homes and live in safe communities, there are some who do not. In the case of Indigenous children, some families and communities are unable to, or are still working to, heal the trauma of past events, including displacement from Country, institutionalisation and abuse. The Stolen Generations also represent a significant cause of trauma. In 2008, an estimated 8% of Indigenous people aged 15 and over reported being removed from their natural family and 38% had relatives who had been removed from their natural family. This trauma can pass to children (inter-generational trauma).Indigenous children may also experience a range of distressing life events including illness and accidents, hospitalisation or death of close family members, exposure to violence, family disintegration (with kin networks fragmented due to forced removals, relationship breakdown and possibly incarceration) and financial stress.Experiencing trauma in childhood can have severe and long-lasting effects; effects that can be overcome by appropriate interventions. This resource sheet examines these effects and explores how they can be tackled. It focuses on the design and delivery of trauma-informed and trauma-specific children’s services and care
The TeCTra online groupwork tool: Scaffolding the learning of self and peer assessment
No full textA reliable assessment strategy for allocating different summative marks for individual contributions in groupwork is a perennial problem that using the TeCTra online tool can resolve. By collecting weekly quantitative and qualitative data to support the individualising of contributions and summative marks the tool supports and scaffolds the studentsâ learning of self and peer assessment understandings, knowledge and skills. This paper discusses the changing design of peer assessment from 1998 to 2008 and the impact of the TeCTRa groupwork tool within a capstone undergraduate subject with large student numbers at UTS. The TeCTra strategy has delivered more diversity of individual summative marks than those reported in the literature and experienced by the authors in the period before the introduction of the tool in 2004. The system for calculating an individual contribution factor has released the academic from the enormous workload otherwise required to process any similar paper-based strategy
Reflections on interactive classroom mLearning and the experiential transactions between students and lecturer
No full textThis paper seeks to address a major deficit in understandings of mobile learning, that is, its lack of a solid theoretical foundation. An overview of existing theoretical concepts of mobile learning is presented, followed by an analysis of interactive classroom systems and the learning that they provide. The implementation of a specific interactive system mInteract in the lectures of a large accounting subject is described. mInteract is a Webbased system using no-to-low cost data-packet technology and provides for interactions from students own Internet-enabled mobile devices. The paper examines, by means of reflections from the lecturer and students, the learning which took place during the implementation. The analysis demonstrates that interactive mobile learning can be interpreted using experiential learning theory, and that both students and lecturers engage in experiential learning. Furthermore, they enter into transactions of knowledge which are facilitated by the mobile learning system

Radiation-induced root surface caries restored with glass-ionomer cement placed in conventional and ART cavity preparations: Results at two years
No full textThe document attached has been archived with permission from the Australian Dental Association (8th Jan 2008). An external link to the publisher’s copy is included.Background: There are no published studies comparing the clinical performances of more-viscous glass-ionomer cement (GIC) restorations when placed using conventional and atraumatic restorative treatment (ART) cavity preparation methods to restore root surface caries. Methods: One dentist used encapsulated Fuji IX GP and Ketac-Molar to restore 72 conventional and 74 ART cavity preparations for 15 patients who had received cervicofacial radiation therapy. Two assessors evaluated the restorations at six, 12, and 24 months for retention, marginal defects and surface wear, and recurrent caries. Results: After two years, the cumulative restoration successes were 65.2 per cent for the conventional and 66.2 per cent for the ART cavity preparations, without statistical or clinical significance (P>0.50). Restoration dislodgement accounted for 82.8 per cent and marginal defects for 17.2 per cent of all failures. There were no instances of unsatisfactory restoration wear or recurrent caries observed. Teeth with three or more restored cervical surfaces accounted for 79.3 per cent of all failures (P<0.0001). Conclusions: For root surface caries restored with GIC, the use of hand instruments only with the ART method was an equally effective alternative to conventional rotary instrumentation for cavity preparation. Larger restorations had higher failures, usually from dislodgement.JY Hu, XC Chen, YQ Li, RJ Smales and KH Yi
