description: In this study a profile is presented of a group of people diagnosed with pre-diabetes and who volunteered to be part of a lifestyle intervention to improve their health. Baseline (pre-intervention) data on biochemical, anthropometric, psychosocial, cultural and lifestyle factors were collected, providing a picture of the extent to which the behaviours of the participants were suboptimal for health. The sample enabled comparison of a Chinese-Australian group with an Anglo-Australian group, as well as male-female comparisons. Participants reported several barriers to healthy eating and exercise, with negative mood, particularly depression, significantly associated with more perceived barriers and weaker motivation to change. Men were less healthy eaters than women. The Anglo-Australian pre-diabetics were characterised by biochemical and anthropomorphic features reflecting the metabolic syndrome, showing risk factors not only for diabetes but also for cardio-vascular disease. The Chinese sample did not reflect metabolic syndrome risk factors to the same extent and, possibly as a consequence, were less motivated to change their behaviour in response to their diagnosis of pre-diabetes. The implications for lifestyle interventions were discussed.

description: Inositol pyrophosphates (PP−IPs) are densely phosphorylated messenger molecules involved in numerous biological processes. PP−IPs contain one or two pyrophosphate group(s) attached to a phosphorylated myo-inositol ring. 5PP−IP5 is the most abundant PP−IP in human cells. To investigate the function and regulation by PP−IPs in biological contexts, metabolically stable analogs have been developed. Here, we report the synthesis of a new fluorinated phosphoramidite reagent and its application for the synthesis of a difluoromethylene bisphosphonate analog of 5PP−IP5. Subsequently, the properties of all currently reported analogs were benchmarked using a number of biophysical and biochemical methods, including co-crystallization, ITC, kinase activity assays and chromatography. Together, the results showcase how small structural alterations of the analogs can have notable effects on their properties in a biochemical setting and will guide in the choice of the most suitable analog(s) for future investigations.

description: The aim of the current study was to examine how bullying by peers relates to self-esteem, school connectedness and motivation for academic success in an Australian high school. Questionnaires were completed by 975 students across years 7 to 12. As predicted, male students were subjected to more direct forms of bullying than female students. However, contrary to expectations, there were no significant differences between males and females in their reported experience of indirect forms of bullying. Also, students in the lower year levels of high school reported being bullied more frequently than students in high year levels. Findings supported predictions that students who were bullied by their peers at school tended to report having lower levels of self-esteem, feeling less connected to their peers, teachers and school, and being less motivated to perform well at school. These results may have implications for school-based intervention programs that are designed to reduce bullying behaviours.
Wave height and crest elevation statistics applicable to offshore wind turbines

Publisher: name: Imperial College London

description: The largest set of field measurements published to date, comprising of 200 million waves and 1 million sea states, has been employed within the present study to produce crest elevation and wave height statistics. The accuracy of the dataset has been ensured by applying a thorough quality control (QC) process. A new improved automated QC method has been proposed within the present study whose novel approach automatically forms an accurate database while increasing the number of waves and minimising the degree of manual checks. The wide range of sea states involved in this large database allows for the detailed examination of the influence of individual parameters on the wave distributions. The present study conclusively demonstrates that the Forristall (2000) model underpredicts crest elevations in steep sea states within the field and that non-linear effects beyond second-order cannot be ignored for design simulations. The Tayfun and Fedele (2007) model has been shown capable of capturing these effects to some extent however it is severely conservative. For wave heights, the Boccotti (1989) model is in very good agreement with the field measurements, adequately accounting for changes in bandwidth. The influence of directionality on wave statistics has also been examined by analysing co-located recordings of the water surface elevation and directional spreading. It was concluded that long-crested seas result in amplifications above the Forristall (2000) model, whilst wave height predictions are in good conservative agreement with the Forristall (1978) model regardless of the degree of directional spreading within a sea state. Additionally, the Adcock & Taylor (2009) method for extracting directional spreading information from single-point measurements, such as wave radars was examined. Its application on 8,095 sea states recorded in the field (more than 20 times the number of the previous largest study) concluded that the method provides accurate predictions of the mean directional spreading value to within +- 20%. Finally, the influence of non-linear wave-structure interactions due to a single, vertical, bottom-mounted, surface-piercing cylinder (representative of a monopile of fixed offshore wind turbines) was considered. Based on the findings it is recommended that a higher-order crest elevation model (such as the Tayfun and Fedele (2007) or the Latheef (2014) distributions) is adopted in design along with a safety factor that takes into account the additional amplifications due to non-linear wave-structure interactions. Specifically, it is suggested to use an amplification factor of 1.189 and to increase it to 1.709 if run up is additionally considered. Finally, the Boccotti (1989) distribution is recommended for wave height predictions along with an amplification factor 1.3 and to increase it to 1.553 should run-up be considered.

description: Recognition of increasing surface air temperatures and climate change has altered governments and public's perception of environmental protection, fossil fuel use and energy efficiency. Specifically, there is increasing awareness that it is possible to contribute, in a substantial way, to reducing energy use and protecting the environment against climate change. One visible example of this is the promulgation of the "green building" concept around the world where new buildings are designed with efficiency in water and energy use in mind. Concomitant with this is the drive towards increasing energy efficiency in public and private buildings through a combination of education and incentive programs. Efficiency in energy use in buildings is usually gained through: (i) maintaining a higher indoor air temperature of 25 oC, (ii) increasing the air recirculation ratio, and (iii) reducing energy loss through improving building insulation in windows. But, what is the effect of an energy efficiency drive on indoor air quality? Specifically, while increasing the amount of air recirculated helps reduce cooling cost for fresh air drawn from hotter air outside, a greater proportion of recirculated air also increases the residence times of volatile organic compounds (VOCs) released from various furniture and upholstery; thereby, degrading indoor air quality, which may impact negatively on occupants' productivity. Similarly, many post-modern buildings have full glass facade where there are little or no gaps between the glass and building structure; thus, such buildings are not "breathable" as contaminants such as dust and VOCs accumulate in the building, contributing to the "sick building syndrome". Hence, there exists a distinct trade-off in our march towards increasing energy efficiency in buildings and maintaining or improving indoor air quality, which impacts on overall productivity of building occupants as well as occupational safety and health. With lower proportion of fresh air intake in each recirculation of air, together with reduced exchange of indoor air with the building exterior, various contaminants such as dust, carbon dioxide, and VOCs accumulate, which collectively reduce the habitability of the indoor environment for work and leisure, which in extreme scenarios, could raise serious safety and health issues. Thus, a holistic and innovative approach is necessary as we tackle the challenges of implementing "green buildings" concept with protection of indoor air quality.
Accuracy and reliability of retinal photo grading for diabetic retinopathy: Remote graders from a developing country and standard retinal photo grader in Australia
Creators: name: Islam, Amirul
Publisher: name: Swinburne
Year: 2024

description: Background: To evaluate the accuracy and reliability of fundus retinal photos graded by local graders in Bangladesh with those graded by an expert at the Centre for Eye Research Australia (CERA) in the context of mass scale diabetic retinopathy (DR) screening in Bangladesh.
Methods: A population-based cross-sectional study of 3,104 adults identified 213 (7.2%) eligible patients with diabetes of age ≥ 40 years in 2012–2013. Retinal photographs were collected using a non-mydriatic digital fundus retinal camera and a two-field imaging protocol. The photos were graded by two remote graders (G1 and G2) who were trained by a retinal specialist (RS) in Bangladesh, by the RS himself, and by a Centre for Eye Research Australia (CERA) grader. The local graders up skilled their grading ability by comparing 30% of the photos graded by the CERA grader with their own grades. Learning from that exercise was applied to the remaining 70% of photos, which were re-graded. Reliability and accuracy of grading amongst the graders were reported using cross tabulation, inter- and intra-grader reliability, and with sensitivity and specificity.
Results: Of 122 eyes from 61 patients, the mild (R1) DR was estimated to be 14 to 25%, pre-proliferative (R2) DR 4–8%, and proliferative (R3) DR 0.8 to 1.6%, whereas 25%, 8%, 18%, and 15% were found to be ungradable by CERA, RS, G1, and G2, respectively. Of 8 (6.6%) eyes identified as R2 by the CERA grader, 5 (63%), 3 (38%) and 3 (38%) were correctly classified as R2, whereas the rest were classified either as R1 or R3 but none were classified as no DR (R0) or ungradable by the RS, G1 and G2, respectively. After getting experience reviewing the 30% test set graded by the CERA grader, the local graders graded moderate and severe DR with 100% accuracy. After excluding ungradable photos, the sensitivity (specificity) relative to the CERA grader was 82% (88%) before and 80% (93%) after training for G1 and 56% (87%) before and 77% (90%) after training for G2. In case of maculopathy, the CERA grader reported 11.2% eyes with maculopathy, which included 100% of the 4.9% by RS, 6.6% by G1, and 7.4% by G2.
Conclusions: Local graders in Bangladesh are able to grade retinal photos with high accuracy if the DR is at least of a moderate level. With appropriate training and experience, local graders have the ability to contribute significantly to the grading of millions of retinal photos, which required grading in resource- poor countries.

description: Identification of adult stem cells is a vital but difficult aspect of stem cell research and regenerative medicine. Due to natural telomerase expression, stem cells are likely to have telomeres markedly longer than their more differentiated counterparts. Unfortunately at this point no method for quick, precise, accurate, and small-scale telomere length measurement exists to add a genetic component to the current arsenal of gene and protein expression analysis used to identify stem cells. To show that we could accurately measure telomere length in adult tissues, qPCR telomere length analysis was applied to human bone marrow and breast tissue demonstrating that in these well-characterized systems, the more immature cells had longer telomeres. Using as a little as 1000 cells sorted by FACS, we used qPCR analysis in the relatively uncharacterized colonic epithelium to show that stem and immature colon cells display longer telomeres than the total colonic epithelium. Applying the telomere length assay to colon cancer showed that tumorigenic colon cancer cells have longer telomeres than the non-tumorigenic bulk of the tumor, as predicted by cancer stem cell theory. Finally, we corroborated our results for normal human colon in mice, by miniaturizing the assay and detecting a difference in telomere length of immature and mature normal mouse colonocytes at an unprecedented single-cell level.

description: Detecting seizure using brain neuroactivations recorded by intracranial electroencephalogram (iEEG) has been widely used for monitoring, diagnosing, and closed-loop therapy of epileptic patients, however, computational efficiency gains are needed if state-of-the-art methods are to be implemented in implanted devices. We present a novel method for automatic seizure detection based on iEEG data that outperforms current state-of-the-art seizure detection methods in terms of computational efficiency while maintaining the accuracy. The proposed algorithm incorporates an automatic channel selection (ACS) engine as a pre-processing stage to the seizure detection procedure. The ACS engine consists of supervised classifiers which aim to find iEEG channels which contribute the most to a seizure. Seizure detection stage involves feature extraction and classification. Feature extraction is performed in both frequency and time domains where spectral power and correlation between channel pairs are calculated. Random Forest is used in classification of interictal, ictal and early ictal periods of iEEG signals. Seizure detection in this paper is retrospective and patient-specific. iEEG data is accessed via Kaggle, provided by International Epilepsy Electro-physiology Portal. The dataset includes a training set of 6.5 h of interictal data and 41 min in ictal data and a test set of 9.14 h. Compared to the state-of-the-art on the same dataset, we achieve 2 times faster in run-time seizure detection. The proposed model is able to detect a seizure onset at 89.40% sensitivity and 89.24% specificity with a mean detection delay of 2.63 s for the test set. The area under the ROC curve (AUC) is 96.94%, that is comparable to the current state-of-the-art with AUC of 96.29%.

description: Post-disaster emergency operations are often chaotic and complex. In most cases, efficiently assigning and scheduling multiple teams of resources are essential for quick and effective disaster relief. Our ongoing research has identified numerous heuristics and mathematical models for resource scheduling, of which only few incorporate synchronization and optimization of multi-team resource scheduling contexts. This paper presents a novel mixed integer linear programming model to minimize the relief operation completion times required for all incidents by optimally assigning and scheduling various teams of non-expendable resources. Key parameters of the model include: number of incidents, severity level of each incident, number relief teams of non-expendable resources, type and capability of relief teams, resource requirements at each incident, travel times, process times and release times. Our primary evaluation of the model considered a case study simulation of resource scheduling for some hypothetical fire emergency operations in a central district of Melbourne metropolitan area. The results are encouraging for practical applications in potential emergency operation management.

Humans at play in the Anthropocene

description: The arrival of the Anthropocene recognises the significant global impact of human activity on the Earth's ecosystems. Building on Huizingia's understanding of the relationship between play and culture, this essay explores the role that play could have in survival strategies or to provide awareness of the impact of human processes in the Anthropocene. In this worldview, play has a primary function in culture through its role in modelling modes of human survival: simulation is good tool for understanding the impact of systems on the world; play enables the possibility to become adaptive and 'hack' the world as conditions change; and lastly, play suggests that a changed philosophical perspective may offer an evolutionary edge for survival in a changing world. Drawing on Levy, Bogost, Harman and Parikka strategies for play are explored using micronations and pervasive games; demonstrated and illustrated by analysis of games from recent experience within the Micronation of Ludea.

description: Role playing has been used as a teaching tool across various disciplines for a very long time1-4. This paper presents on-line role playing simulations in support of the e-learning components of the problem based learning (PBL) programs in the School of Electrical Engineering, Victoria University (VU) that commenced in 2006. There are many challenges in PBL such as the design problems that will allow students to explore many facets of a problem and eventually learn what is needed to solve it. Another challenge is to try and make the problems constructively aligned with the desired learning outcomes of the unit of study. Nonetheless, students will be working in teams on different aspects of the problems. The issue we are faced with in regards to team work is trying to engage students in the problems and to make the problem exciting. As these problems will mimic industry problems, role playing has brought the problems to life. The results indicated a positive outcome.

description: Online learning is a ubiquitous part of higher education in Australia, yet there is little in the way of design principles or learning design models to guide the design of online learning environments that are inclusive and supportive of Indigenous students. This is a significant issue given the inequitable participation and outcomes of Indigenous people in higher education. This study set out to develop principles for the design of online learning environments that are inclusive of Indigenous students and which enhance their experiences of online learning. Educational Design Research (EDR) was used as the guiding methodological framework. The research was conducted over three micro-cycles of the EDR phase of analysis and exploration, with yarning used as the main method of data collection. The yarning approach produced a rich picture of the experiences of online learning of the nineteen Indigenous participants. Qualitative analysis of the data drawn from yarning resulted in the identification of ten themes that encapsulate the experiences of Indigenous higher education students in online learning. These themes support the finding that a relational epistemology underpins the learning of Indigenous higher education students. The themes formed the foundation of the development of six principles for the design of online learning environments that are inclusive of Indigenous higher education students. The study also concluded that whole of institution approaches are needed to enhance the learning and experiences of Indigenous students. To this end sixteen recommendations for research, policy and practice are presented. The research findings address a need for guidelines that education designers, teaching academics and other interested people and institutions can use in the design of inclusive online learning environments that will enhance the experiences of Indigenous higher education students in online learning.

description: Due to high functionality integration in electronic devices and the ever increasing requirements for low power devices, there is an urgent need for novel low power approaches. The advancement in technology scaling has made it feasible to incorporate the extra functionality, however by increasing devices sensitivity to variations, the overall device yield decreases. Process and temperature variations are the biggest contributing factors in delay and leakage current, especially in mixed-signal circuitry. This paper considers the possibility of reducing the effect of variations to improve linearity on transistor-only DACs (MOSFET DAC) operating in weak inversion. The main drawback in biasing a transistor in the weak inversion region is the poor transistor mismatch which will affect the overall linearity. However, the mismatch can be reduced by introducing a compensation circuits. The circuits are designed with 0.13μm ST-Microelectronic low leakage CMOS technology.

Mineral transformations and element fluxes during propylitic alteration in porphyry ore systems: a case study of the Oyu Tolgoi Porphyry Cu-Au deposits, Mongolia
Creators: name: Hart-Madigan, Lisa
Publisher: name: Imperial College London
Year: 2018

description: A new frontier in exploration geochemistry is the development of techniques that detect orebodies located at depth. The propylitic halo is the most extensive footprint of porphyry systems and may be the only exposed part of a buried ore system, so is at the heart of such research. Key trace elements within propylitic minerals can vary systematically with distance from known orebodies, therefore, can be used as vectors to ore. Additionally, certain trace element signatures within the same minerals are unique to mineralised systems and are useful fertility indicators. Porphyry systems form in active tectonic settings so alteration can be overprinted by later events, particularly in ‘older’ camps such as the Palaeozoic Oyu Tolgoi deposits of Mongolia. In such complex terranes, successful exploration relies on distinguishing porphyry-related assemblages from later overprinting events. The porphyry alteration halo at Oyu Tolgoi is zoned, with potassic and sericitic alteration in the core hosting the orebodies and flanked by the innermost subzone of the propylitic halo, characterised by pyrite-K-feldspar-epidote. Beyond this is the epidote subzone, characterised by epidote- albite-calcite- titanite-andradite. The outermost chlorite subzone is truncated by faults and rarely observed. New LA-ICP-MS U-Pb dating of propylitic titanite identified hydrothermal events occurring at approximately 370 Ma, 340-320 Ma and 290 Ma. These dates broadly match known magmatic events: porphyry mineralisation in the late Devonian; the intrusion of granodiorite plutons in the Carboniferous; and the emplacement of the giant Khanbogd Granite in the Permian. The distribution of these dated samples suggests that post-mineralisation alteration overprinted significant portions of the porphyry halo. Using the samples with dated alteration, it has been possible to develop a geochemical classification system that can distinguish between porphyry-related epidote, and later non-porphyry epidote. The results have been integrated to create a workflow for exploration that has identified prospective targets across the wider district.
Improving the stability of organometallic halide perovskite photoactive layers and solar cells via film passivation with iodide salts

description: Methylammonium lead halide perovskite materials are receiving great attention as promising candidates for industrial applications, but their long-term stability when used in solar devices remains problematic. In particular, the perovskite layers based on CH3NH3PbI3 (methylammonium lead iodide, MAPI) experience severe degradation caused by oxygen and light. An understanding of this process, and how to enhance stablility, is distinctly important in the evolution of devices utilising perovskite. The systematic study of MAPI-based solar cells is investigated in first results chapter. Factors such as compact layer thickness, mesoporous layer thickness, TiCl4 surface treatment and Spiro-OMeTAD oxidation are studied. Furthermore, the issues of how photo- and oxygen-induced degradation, and thus the superoxide formation, will affect the efficiency and stability of the perovskite devices are addressed. The second results chapter builds on the knowledge that iodide vacancies in MAPI crystals are the most-preferred sites for superoxide formation. First, a film passivation technique was devised using methylammonium iodide (MAI) coating. The treatment could effectively reduce the suface defects and improve device stability by inhibiting superoxide generation. Second, the relation between superoxide formation and device stability as a function of bromide composition for Br-I mixed halide solar cells is examined. Use of an alternative passivating agent, namely phenylethylammonium iodide (PEAI) shows that it is highly effective on enhancing film and device stability under light and oxygen without reducing performance. The results confirm that this iodide salt could help to reduce problematic vacancies and therefore lower superoxide yields and improve device stability. Extending the investigation further, in final results chapter, a novel Iodide Salt Assisted Anti-solvent Treatment (ISAAT) for preparing MAPI layer is developed. The ISAAT strategy could effectively enhance the morphology and crystallinity of the perovskite films. With ISAAT treatment, devices are more stable and efficient than without treatment. More importantly, this ISAAT method shows more reproducibility than direct PEAI treatment, thereby elucidating an effective methodology of future design and optimisation of perovskite solar cells with better efficiency, long-term durability and reproducibility.

description: Try to imagine Wolf Creek with an Australia style marketing and tourism campaign. The John Jarratt action figure. Milk cartons proclaiming The Thrill Is In The Hunt. Such an imagining invites us to ponder the capacity of a 'national cinema' to reflect or refract 'national identity'. It allows us to ask whether the idea of a 'national cinema' is relevant (or in fact ever was) in a world where the rapid and global circulation of images ensures that we are never able to control or distil them into any kind of meaningful semiotic assemblage for very long. In such a world, is national identity anything more than a marketing strategy? These ideas are explored in this article by way of the reflexive remix in order to examine, more broadly, the functioning of reflexive remix as a mode of critical discourse. Can reflexive remix perform criticism, an applied grammatological critique? Drawing on and remixing the writings of Greg Ulmer, Jacques Derrida and Marshall McLuhan, the author argues for a positive response to such questions.

description: The already challenging task of identifying the cause of a bug becomes even more cumbersome if those bugs disappear or change their behavior under observation. Such bugs occur in a range of contexts including elusive concurrency bugs as well as unintended system alterations during debugging and—as a pun on the name of Werner Heisenberg—are often referred to as Heisenbugs. Heisenbugs can be caused by various sources of nondeterminism on different system levels, many of which developers and testers might not even be aware of. This paper provides formal foundations for rigorously reasoning about causes of Heisenbugs. It provides a formal definition of Heisenbugs in terms of a hyperproperty and introduces a framework for determining the causality of Heisenbugs in presence of multiple candidate causes based on said hyperproperty. We analyze the properties of causes and the implications on practical causal analyses.

description: Background: Health services that operate 7 days per week are under pressure to show the increased cost of providing weekend services can be measured in improved patient outcomes. The evidence for weekend allied health services in acute medical and surgical wards is weak and there is wide variation between the services offered at different hospitals. Methods: This qualitative study was undertaken during a multi-site stepped wedge randomised controlled trial involving twelve acute medical and surgical wards from two Australian hospitals, in which weekend allied health services were removed before being reinstated with a stakeholder driven model. In-depth interviews were conducted with twenty-two staff responsible for managing weekend services at the involved hospitals. Participants were asked about their perceptions of the advantages and disadvantages of providing a weekend allied health service. Results: Managers perceive the services improve patient flow and quality of care and reduce adverse incidents, such as falls and intensive care admissions. They also highlighted the challenges involved in planning, staffing and managing these services and the uncertainties about how to provide it most effectively. Conclusions: Rising healthcare costs provide opportunity for public and professional debate about the most effective way of providing weekend allied health care services, particularly when health services provide limited other weekend services. Some managers perceived weekend allied health services to improve patient quality of care, but without studies which show these services on acute medical and surgical wards clearly change patient outcomes or provide health economic gains, these resources may need to be redirected. The resources may be better spent in areas with clear evidence to show the addition of weekend allied health services improves patient outcomes, such as on acute assess units and rehabilitation wards.
Household bandwidth and the 'need for speed': Evaluating the impact of active queue management for home internet traffic

description: In this paper, we aim to contribute to the policy debate on bandwidth needs by considering more closely what happens in household networks. We draw upon both social and technical studies modelling household applications and their uses to show how queue management protocols impact bandwidth needs. We stress the impact of internet traffic streams interfering with each other, and describe three different categories of internet traffic. We demonstrate how the use of active queue management can reduce bandwidth demands. In doing so we consider how, and to what degree, household internet connections are a constraint on internet use. We show that speed demand predictions are skewed by a perceived need to protect the Quality of Service experienced by latency-sensitive services when using current gateway technologies.
