Expanding The Vision: Synthetic Phonics In Action Ii, Deslea Konza

Research outputs 2013

The Yorke and Mid North - Roxby Downs Area School (YMN-RDAS) Literacy Project in 2013 was largely an extension of the literacy project conducted with the YMN region of the South Australian Department of Education and Child Development in 2012. The 2012 project outcomes were very positive (see Konza, 2013) and funding was made available for continuation of the main elements of the project with another cohort of primary schools in 2013. As was the case with the YMN 2012 project, it was designed to ‘value-add’ to the Principals as Literacy Leaders (PALL) project which had been implemented in the …

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 …

Stories Of Snow And Fire: The Importance Of Narrative To A Critically Pluralistic Environmental Aesthetic, John C. Ryan

Research outputs 2013

Written narratives enable humans to appreciate the natural world in aesthetic terms. Firstly, narratives can galvanize for the reader a sense for another person’s experience of nature through the aesthetic representation of that experience in language. Secondly, narratives can encode and document for the human appreciator as writer an experience of nature in aesthetic terms. Through different narrative lenses, the compelling qualities of environments can be crystallized for both the reader (who vicariously experiences nature through language) and the human appreciator (who directly experiences nature through the senses). However, according to philosopher Allen Carlson’s “natural environmental model” of landscape aesthetics, …

Patterns Of Physical And Psychological Development In Future Teenage Mothers, Daniel Nettle, Thomas E. Dickins, David A. Coall, Paul De Monrnay Davis

Research outputs 2013

Background and objectives: Teenage childbearing may have childhood origins and can be viewed as the outcome of a coherent reproductive strategy associated with early environmental conditions. Life-history theory would predict that where futures are uncertain fitness can be maximized through diverting effort from somatic development into reproduction. Even before the childbearing years, future teenage mothers differ from their peers both physically and psychologically, indicating early calibration to key ecological factors. Cohort data have not been deliberately collected to test life-history hypotheses within Western populations. Nonetheless, existing data sets can be used to pursue relevant patterns using socioeconomic variables as indices …

Technology Corner: Visualising Forensic Data: Evidence Guidelines (Part 2), Damian Schofield, Ken Fowle

Research outputs 2013

Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence) and analysis (for example, network capability assessment, data file reconstruction and planning scenarios). Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter) to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an …

Assessment For “Digital First Language” Speakers: Online Video Assessment And Feedback In Higher Education, Will Turner, John West

Research outputs 2013

While feedback has been highlighted as the most powerful influence on student achievement, Weaver (2006) noted that up to 40% of tertiary students lack confidence in their feedback and many students express dissatisfaction with this aspect of their student experience (Rodway-Dyer, Dunne, & Newcombe, 2009). Chasms remain between academic feedback and student feed forward outputs, as research suggests that feedback is undervalued by “unresponsive” tertiary students due to misunderstanding, inconsistencies and lack of clarity, and that feedback is not as effective as staff imagine. This paper explores student and staff perceptions of a video feedback model for tertiary institutions. Each …

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 …

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, …

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 …

Latrepirdine: Molecular Mechanisms Underlying Potential Therapeutic Roles In Alzheimer’S And Other Neurodegenerative Diseases, P R. Bharadwaj, K A. Bates, T Porter, E Teimouri, G Perry, J W. Steele, S Gandy, D Groth, R N. Martins, Giuseppe Verdile

Research outputs 2013

Latrepirdine (Dimebon^TM) was originally marketed as a non-selective antihistamine in Russia. It was repurposed as an effective treatment for patients suffering from Alzheimer’s disease (AD) and Huntington’s disease (HD) following preliminary reports showing its neuroprotective functions and ability to enhance cognition in AD and HD models. However, latrepirdine failed to show efficacy in phase III trials in AD and HD patients following encouraging phase II trials. The failure of latrepirdine in the clinical trials has highlighted the importance of understanding the precise mechanism underlying its cognitive benefits in neurodegenerative diseases before clinical evaluation. Latrepirdine has shown to affect …

Isbister, Seyed Shahmy, Fahim Mohamed, Chandana Abeysinghe, Harendra Karunathilake, Ariaranee Ariaratnam, Tamara E. Jacoby-Alner, Claire L. Cotterell, Simon G A Brown

Research outputs 2013

Background:Snake bite is one of the most neglected public health issues in poor rural communities worldwide. In addition to the clinical effects of envenoming, treatment with antivenom frequently causes serious adverse reactions, including hypersensitivity reactions (including anaphylaxis) and pyrogenic reactions. We aimed to investigate the immune responses to Sri Lankan snake envenoming (predominantly by Russell's viper) and antivenom treatment.Methodology/Principal Findings:Plasma concentrations of Interleukin (IL)-6, IL-10, tumor necrosis factor α (TNFα), soluble TNF receptor I (sTNFRI), anaphylatoxins (C3a, C4a, C5a; markers of complement activation), mast cell tryptase (MCT), and histamine were measured in 120 Sri Lankan snakebite victims, both before and …

Environmental factors such as stress, anxiety and depression are important to consider with the global increase in chronic diseases such as cardiovascular diseases, cancer, stroke, obesity, diabetes and neurodegenerative diseases. Brain metabolic diseases associated with conditions such as obesity and diabetes require early intervention with diet, lifestyle and drug therapy to prevent diseases to various organs such as the liver with non alcoholic fatty liver disease (NAFLD) and other organs such as the heart, lungs thyroid, pancreas, brain, kidneys and reproductive systems. Behavioural stress and the molecular mechanisms that are involved in neuroendocrine diseases such as insulin resistance in obesity …

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.

Synthesis And Antioxidant, Anticancer, And Antimicrobial Activities Of Palmityl Ester Derivative Of Carnosic Acid, Asharani Prasad

Food Safety

Carnosic acid (CA) along with carnosol (CAR) is the strongest phenolic diterpene antioxidants (PDAs) present in rosemary plant. However, CA has low antioxidant activity in emulsion-type food system due to its polar nature. The identification and characterization of the anticancer and antimicrobial properties of natural products and their semisynthetic derivative such as that of CA and CAR have received significant interest over the years. The goals of this research were to synthesize lipophilic palmityl derivative (PE) of CA and study its antioxidant activity in bulk and emulsified corn oil. Anticancer properties against CCRF-CEM, K-562 and P388D1 leukemia cell lines and …

The Cave Environment Influencing The Lipid Profile And Hepatic Lipogenesis Of The Fish Ancistrus Cryptophthalmus Reis, 1987 (Siluriformes: Loricariidae), Valquíria Aparecida Alves Bastos, Rodrigo Lopes Ferreira, Daniel Cardoso Carvalho, Marina Lages Pugedo, Luciana De Matos Alves Pinto

International Journal of Speleology

The metabolism of hypogean organisms is frequently molded by the cave environment traits, especially food scarcity. The aim of the present work was to evaluate the influence of such environment on lipid composition and hepatic lipogenesis in the fish Ancistrus cryptophthalmus. For this, the species was compared to an epigean population of the same species. A greater accumulation of total lipids was observed in the cave-dwelling fish (18.36 g/100 g tissue) compared to the surface fish (14.09 g/100 g tissue). The muscle fatty acid profile also varied between the populations. Arachidonic acid was only detected in the epigean fish, while …

Phototactic Behaviour Of Subterranean Copionodontinae Pinna, 1992 Catfishes (Siluriformes, Trichomycteridae) From Chapada Diamantina, Central Bahia, Northeastern Brazil, Bianca Rantin, Maria Elina Bichuette

International Journal of Speleology

The phototactic behaviour of three Copionodontinae (Trichomycteridae) catfish species (two troglobites and one epigean) from Chapada Diamantina was studied in order to detect modifications related to isolation in the subterranean environment. Differences in response under different luminosities were detected and, unlike other cavefish, Copionodontinae cave species have shown to be more photophobic than the epigean syntopic to them. The troglobitic Glaphyropoma spinosum is the most photophobic, presenting this behaviour under all light intensities, and more homogeneous regarding morphological characters. It suggests that this population is probably isolated for a longer time in the subterranean environment compared to Copionodon sp. n., …

La Serreta Endokarst (Se Spain): A Sustainable Value?, Antonia D. Asencio, Teodoro Espinosa

International Journal of Speleology

La Serreta endokarst (SE Spain), which UNESCO declared a World Heritage Site in 1998, was considered a sanctuary with cave art and one of the most important archaeological sites in the Mediterranean region for both the remains it hosts and the spectacular karstic landscape at the site.

To coincide with the 40th anniversary of its discovery, the La Serreta cave-chasm was adapted for public use with the intention of showing visitors the remains, which date back to prehistoric times. The solution included attempts to minimize contact with the valuables in the cave in order to alter the existing remains as …

Layer-Bounding Surfaces In Stalagmites As Keys To Better Paleoclimatological Histories And Chronologies, Loren Bruce Railsback, Pete D. Akers, Lixin Wang, Genevieve A. Holdridge, Ny Riavo Voarintsoa

International Journal of Speleology

Petrographic recognition of layer-bounding surfaces in stalagmites offers an important tool in constructing paleoclimate records. Previous petrographic efforts have examined thickness of layers (a possible proxy for annual rainfall) and alternation of layers in couplets (a possible indicator of seasonality). Layer-bounding surfaces, in contrast, delimit series of layers and represent periods of non-deposition, either because of exceptionally wet or exceptionally dry conditions.

Two types of layer-bounding surfaces can be recognized according to explicitly defined petrographic criteria. Type E layer-bounding surfaces are surfaces at which layers have been truncated or eroded at the crest of a stalagmite. Keys to their recognition …
