In this paper, we explore this potential killer application for mobile intelligence. We propose combining small, light-weight AI/CI libraries with AI/CI services in the cloud for the heavy lifting. To make our ideas more concrete, we describe …

Digital Representation Of Visual Artworks For High-Stakes Assessment, Christopher P. Newhouse

Research outputs 2013

The collection and marking of student artwork across a large jurisdiction such as Western Australia is challenging where the work is submitted to a central location to be marked by experts and returned to students. An alternative approach would be to submit digital representations of the artworks online for marking. However, to give a valid and reliable measure the representations would need to be of adequate quality. Further, judgements of artworks are necessarily subjective giving concern about the reliability of marking for high-stakes assessment. The comparative pairs method of marking lends itself to addressing this problem and is feasible where …

Review Of Kidney Disease Among Indigenous People, Sasha A. Stumpers, Neil J. Thomson

Research outputs 2013

Kidney disease is a significant health problem for all Australians, but severe kidney disease is more common among Indigenous people than among non- Indigenous people. In particular, the prevalence of chronic kidney disease (CKD) and the overall levels of end-stage kidney disease (ESKD) among Aboriginal and Torres Strait Islander peoples are consistently reported as significantly higher than among other Australians. Information on CKD among Indigenous Australians is available from self-reported survey data, as well as from community-based studies and screening programs [10-20] but the main focus in the literature has been on ESKD. The incidence of ESKD is especially high …

Release Of Dissolved Organic Carbon From Seagrass Wrack And Its Implications For Trophic Connectivity, Paul S. Lavery, Kathryn M. Mcmahon, Julia Weyers, Mary C. Boyce, Carolyn Elizabeth Oldham

Research outputs 2013

The export of old leaves and stems (wrack) from seagrass meadows provides a mechanism for trophic connectivity among coastal ecosystems. As little of this wrack is consumed by mesograzers, leached dissolved organic carbon (DOC) may determine the importance of wrack as a trophic subsidy. However, few studies have examined the effect of seagrass type or age on the release of DOC or its bioavailability. We examined the amount and composition of DOC released from different wrack: Posidonia sinuosa, Amphibolis antarctica and the alga Laurencia sp. We then examined the effect of age on DOC leaching from P. sinuosa wrack. The …

Masculinity, Mass Consumerism And Subversive Sex: A Case Study Of Second Life's 'Zeus' Gay Club, Judith A. Elund

Research outputs 2013

This article is a case study of a Second Life region in reference to the prevailing attitudes of sexual conservatism and the growing acceptance of homosexual coupling. The site of Zeus is a contested site of legitimacy in view of tensions regarding masculinity as it applies to sex, sexuality, gender conformity and consumption practices. Furthermore, it is representative of the tensions between an acceptable, albeit conservative gay male identity, and the subversive hyper-sexual and hyper-masculine subject of desire.

Are Human Rights Redundant In The Ethical Codes Of Psychologists?, Alfred Allan

Research outputs 2013

The codes of ethics and conduct of a number of psychology bodies explicitly refer to human rights, and the American Psychological Association recently expanded the use of the construct when it amended standard 1.02 of the Ethical Principles of Psychologists and Code of Conduct. What is unclear is how these references to human rights should be interpreted. In this article I examine the historical development of human rights and associated constructs and the contemporary meaning of human rights. As human rights are generally associated with law, morality, or religion, I consider to which of forms of these references most likely …

New Orleans: A Disaster Waiting To Happen?, Rodney J. Giblett

Research outputs 2013

New Orleans is one of a number of infamous swamp cities—cities built in swamps, near them or on land “reclaimed” from them, such as London, Paris, Venice, Boston, Chicago, Washington, Petersburg, and Perth. New Orleans seemed to be winning the battle against the swamps until Hurricane Katrina of 2005, or at least participating in an uneasy truce between its unviable location and the forces of the weather to the point that the former was forgotten until the latter intruded as a stark reminder of its history and geography. Around the name “Katrina” a whole series of events and images congregate, …

Dietary Patterns Associated With Alzheimer's Disease And Related Chronic Disease Risk: A Review, Samantha L. Gardener, Stephanie R. Rainey-Smith, Jennifer Keogh, Suzanne Mathieson, Ralph N. Martins

Research outputs 2013

The world’s population is growing older due to improved healthcare and nutrition. As a result, Alzheimer’s disease (AD) prevalence is rapidly increasing. The focus of the current research climate is shifting from understanding AD pathology and diagnosis to primary prevention and intervention strategies. Diet represents one potential intervention strategy accessible to all. Accumulating evidence suggests diet plays a major role in risk and development of AD and AD-related chronic diseases of the periphery like cardiovascular disease (CVD) and diabetes. This paper reviews studies that have explored the relationship between “a priori” dietary patterns, AD and AD-related chronic disease risk. The …

Meta-Analysis Reveals Complex Marine Biological Responses To The Interactive Effects Of Ocean Acidification And Warming, Ben P. Harvey, Dylan Gwynn-Jones, Philippa J. Moore

Research outputs 2013

Ocean acidification and warming are considered two of the greatest threats to marine biodiversity, yet the combined effect of these stressors on marine organisms remains largely unclear. Using a meta-analytical approach, we assessed the biological responses of marine organisms to the effects of ocean acidification and warming in isolation and combination. As expected biological responses varied across taxonomic groups, life-history stages, and trophic levels, but importantly, combining stressors generally exhibited a stronger biological (either positive or negative) effect. Using a subset of orthogonal studies, we show that four of five of the biological responses measured (calcification, photosynthesis, reproduction, and survival, …

A Necrotic Stimulus Is Required To Maximize Matrix-Mediated Myogenesis In Mice, Drew Kuraitis, Maria Grazia Berardinelli, Erik J. Suuronen, Antonio Musaro

Research outputs 2013

Biomaterials that are similar to skeletal muscle extracellular matrix have been shown to augment regeneration in ischemic muscle. In this study, treatment with a collagen-based matrix stimulated molecular myogenesis in an mdx murine model of necrosis. Matrix-treated animals ran ≥ 40% further, demonstrating functional regeneration, and expressed increased levels of myogenic transcripts. By contrast, matrix treatment was unable to induce transcriptional or functional changes in an MLC/SOD1G93A atrophic mouse model. In vitro, satellite cells were cultured under standard conditions, on matrix, in the presence of myocyte debris (to simulate a necrotic-like environment) or with both matrix and necrotic stimuli. Exposure …

Pine As Fast Food: Foraging Ecology Of An Endangered Cockatoo In A Forestry Landscape, William Stock, Hugh Finn, Jackson Parker, Ken Dods

Research outputs 2013

Pine plantations near Perth, Western Australia have provided an important food source for endangered Carnaby’s Cockatoos (Calyptorhynchus latirostris) since the 1940s. Plans to harvest these plantations without re-planting will remove this food source by 2031 or earlier. To assess the impact of pine removal, we studied the ecological association between Carnaby’s Cockatoos and pine using behavioural, nutritional, and phenological data. Pine plantations provided high densities of seed (158 025 seeds ha21) over a large area (c. 15 000 ha). Carnaby’s Cockatoos fed throughout these plantations and removed almost the entire annual crop of pine cones. Peak cockatoo abundance coincided with …

Reversibility Of Membrane N-Glycome Of Hela Cells Upon Treatment With Epigenetic Inhibitors, Tomislav Horvat, Martina Dezeljin, Irma Redzic, Darko Barisic, Maja H. Bosnar, Gordan Lauc

Research outputs 2013

Glycans are essential regulators of protein function and are now in the focus of research in many physiological and pathophysiological processes. There are numerous modes of regulating their biosynthesis, including epigenetic mechanisms implicated in the expression of glyco-genes. Since N-glycans located at the cell membrane define intercellular communication as well as a cellular response to a given environment, we developed a method to preferentially analyze this fraction of glycans. The method is based on incorporation of living cells into polyacrylamide gels, partial denaturation of membrane proteins with 3 M urea and subsequent release of N-glycans with PNGase F followed by …

Trkb Receptor Signalling: Implications In Neurodegenerative, Psychiatric And Proliferative Disorders, Vivek K. Gupta, Yuyi You, Veer Gupta, Alexander Klistorner, Stuart L. Graham

Research outputs 2013

The Trk family of receptors play a wide variety of roles in physiological and disease processes in both neuronal and non-neuronal tissues. Amongst these the TrkB receptor in particular has attracted major attention due to its critical role in signalling for brain derived neurotrophic factor (BDNF), neurotrophin-3 (NT3) and neurotrophin-4 (NT4). TrkB signalling is indispensable for the survival, development and synaptic plasticity of several subtypes of neurons in the nervous system. Substantial evidence has emerged over the last decade about the involvement of aberrant TrkB signalling and its compromise in various neuropsychiatric and degenerative conditions. Unusual changes in TrkB signalling …

Pathology Associated With Aav Mediated Expression Of Beta Amyloid Or C100 In Adult Mouse Hippocampus And Cerebellum, Eleanor S. Drummond, Jill Muhling, Ralph Martins, Linda K. Wijaya, Erich M. Ehlert, Alan R. Harvey

Research outputs 2013

Accumulation of beta amyloid (Ab) in the brain is a primary feature of Alzheimer’s disease (AD) but the exact molecular mechanisms by which Ab exerts its toxic actions are not yet entirely clear. We documented pathological changes 3 and 6 months after localised injection of recombinant, bi-cistronic adeno-associated viral vectors (rAAV2) expressing human Ab40- GFP, Ab42-GFP, C100-GFP or C100V717F-GFP into the hippocampus and cerebellum of 8 week old male mice. Injection of all rAAV2 vectors resulted in wide-spread transduction within the hippocampus and cerebellum, as shown by expression of transgene mRNA and GFP protein. Despite the lack of accumulation of …

The Guinea Pig As A Model For Sporadic Alzheimer's Disease (Ad): The Impact Of Cholesterol Intake On Expression Of Ad-Related Genes, Mathew Sharman, Seyyed H.M. Nik, Mengqi Chen, Daniel Ong, Linda K. Wijaya, Simon Laws, Kevin Taddei, Morgan Newman, Michael Lardelli, Ralph Martins, Guiseppe Verdile

Research outputs 2013

We investigated the guinea pig, Cavia porcellus, as a model for Alzheimer’s disease (AD), both in terms of the conservation of genes involved in AD and the regulatory responses of these to a known AD risk factor - high cholesterol intake. Unlike rats and mice, guinea pigs possess an Ab peptide sequence identical to human Ab. Consistent with the commonality between cardiovascular and AD risk factors in humans, we saw that a high cholesterol diet leads to up-regulation of BACE1 (b-secretase) transcription and down-regulation of ADAM10 (a-secretase) transcription which should increase release of Ab from APP. Significantly, guinea pigs possess …

Increased Risk For Obesity And Diabetes With Neurodegeneration In Developing Countries [Journal Article], Ian J. Martins

Research outputs 2013

The incidence of global obesity and Type 2 diabetes has increased and is predicted to rise to 30% of the global population. Diet and lifestyle factors are incapable to resolve the increased incidence for obesity and diabetes in various populations of the world. Developing countries have come to the forefront because of the higher diabetic epidemic. The urbanization may possibly provide an explanation for the global diabetic epidemic. In Western countries the metabolic syndrome and non alcoholic fatty liver disease (NAFLD) have reached 30 % of the population and now at present NAFLD afflicts 20% of developing populations. Western diets …

Unearthing Augusta: Landscapes Of Royalization On Roatan Island, Honduras, Lorena Diane Mihok

USF Tampa Graduate Theses and Dissertations

In 1742, the settlement of Augusta was established as an outpost of English royalization on Roatán Island, Honduras. This military camp housed a mix of English soldiers, English colonists, and local indigenous Miskitu peoples. While the settlement was occupied for only a brief span of seven years, the material record of the community provides insight into Miskitu-English interactions during the royalization process. Royalization encompassed strategies deployed by the English Crown to bring about loyalty to the state. In this dissertation, I discuss the concept of royalization from an agent-centered perspective to consider the intentions behind the occupants' usage of objects …

Synthesis Of Titanium Dioxide Photocatalyst With The Aid Of Supercritical Fluids, Haitao Li

USF Tampa Graduate Theses and Dissertations

Titanium Dioxide (TiO2) emerged as one of the most popular photocatalysts since 1970's. However, its photocatalytic activity requires UV irradiation due to its large band gap unless further functionalization or modifications are performed. Furthermore, recovery issue has always been a major drawback, if the more effective form nano particles are utilized.

The key objectives of this research were synthesizing new TiO2 based photocatalyst systems that are effective with both the UV and the visible light while utilizing novel superior environmentally friendly techniques enabling development of nano-structured photocatalysts that can be easily recovered. In this dissertation research, highly porous nano-structured TiO2/WO3/Fe3+ …

Fate Of Polybrominated Diphenyl Ethers During Wastewater Treatment Process Producing Reclaimed Water, Kristy Siegel

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs), flame retardants, have been applied to consumer goods, such as furniture, electrical devices, textiles, and appliances for decades. Due to their physico-chemical properties, PBDEs are semi-volatile and easily leach off the consumer good during aging, stress, or normal wear and tear of the good. Once airborne, they pose an environmental health threat because they can adsorb onto dust particles, soil, or other particulates that can be inhaled, ingested, or come into contact with the dermal layer. Additionally, PBDEs have a molecular structure similar to other persistent organic pollutants, such as polychlorinated biphenyls and polychlorinated dibenzo-p-dioxins and …

Development Of An Investigator-Designed Questionnaire Concerning Childbirth Delivery Options Based On The Theory Of Planned Behavior, Chun-Yi Tai

USF Tampa Graduate Theses and Dissertations

This study responds to the globally increasing rate of caesarean section, and specifically to the very high rate of elective caesarean section among Taiwanese mothers as evidence suggests that such elective caesareans pose potential health risks for mothers and babies. The purpose of this study was to develop and evaluate a multi-component instrument based on the theory of planned behavior (TPB) to better understand Taiwanese pregnant women's decisions regarding their childbirth delivery options (spontaneous vaginal delivery or elective caesarean section). The study was a four-phased mixed method design. First, the TPB guided item development and instrument drafting. Second, pretesting and …
