"A Big Influence On My Teaching Career And My Life": A Longitudinal Study Of Learning To Teach English Pronunciation, Michael S. Burri, Amanda Ann Baker

Faculty of Social Sciences - Papers (Archive)

Inquiry into learning to teach pronunciation is a growing area within the second language teacher education research paradigm. To what extent this learning process extends into instructors' early years of teaching pronunciation has yet to be explored. This article is a response to this need by exploring the 3.5-year trajectory of five teachers learning to teach English pronunciation. The study was conducted in two phases. In Phase 1, pre- and post-course questionnaires, weekly observations of the lectures, focus groups interviews, final post-course interviews, and the participants' final assessment task were triangulated to examine the development of participants' cognitions during a …

Mezirow Moments: The Value Of Conferences For A Mother Returning To Study, Skye Playsted

Faculty of Social Sciences - Papers (Archive)

It's not easy to change career paths, but it is something that teachers often consider after working in one field for many years. This can mean a return to study, but as Adult Education experts have noted, older learners usually face some specific barriers in returning to school that younger learners do not, and sometimes these barriers prevent them from trying. And if you are a mother, like I am, even going to a conference can be difficult. This is my story of the challenges I faced in returning to study, and of the people who helped me to overcome …

A Laboratory Study On Fluidization Of Subgrade Under Cyclic Train Loading, Buddhima Indraratna, Mandeep Singh, Thanh Trung Nguyen, Serge Leroueil, Aruni Lakmali Abeywickrama Bamunusing Kankanamge, Richard B. Kelly, Tim Neville

Faculty of Engineering and Information Sciences - Papers: Part B

A long term issue that has hampered the efficient operation of heavy haul tracks is the migration of fluidized fines from the shallow soft subgrade to the overlying ballast, i.e., mud pumping. This paper presents a series of undrained cyclic triaxial tests, where realistic cyclic loading conditions were simulated at low confining pressure that is typical of shallow subgrade beneath a ballast track. Subgrade soil specimens with a low plasticity index collected from a field site with recent history of mud pumping were tested at frequencies from 1.0 to 5.0 Hz and a cyclic stress ratio (CSR) from 0.1 to …

A Noise Study Of The Psw Signature Family: Patching Drs With Uniform Distribution, Arnaud Sipasseuth, Thomas Plantard, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part B

At PKC 2008, Plantard et al. published a theoretical framework for a lattice-based signature scheme, namely Plantard-Susilo-Win (PSW). Recently, after ten years, a new signature scheme dubbed the Diagonal Reduction Signature (DRS) scheme was presented in the National Institute of Standards and Technology (NIST) PQC Standardization as a concrete instantiation of the initial work. Unfortunately, the initial submission was challenged by Yu and Ducas using the structure that is present on the secret key noise. In this paper, we are proposing a new method to generate random noise in the DRS scheme to eliminate the aforementioned attack, and all subsequent …

Study On Performance Evaluation Of Co2 Heat Pump System Integrated With Thermal Energy Storage For Space Heating, Zhihua Wang, Yuxin Zheng, Fenghao Wang, Mengjie Song, Zhenjun Ma

Faculty of Engineering and Information Sciences - Papers: Part B

CO2 heat pumps have drawn a great deal of attention owing to their advantages of high efficiency and environmental friendly for heating water under low ambient temperature. However, the system performance is not desirable and shows a lower COP for space heating, especially for a radiator as heating terminal, due to the higher inlet water temperature at the gas cooler, which causes a large throttle loss when the refrigerant flow through the throttling device. To tackle this issue, a transcritical CO2 heat pump system integrated with thermal energy storage (TES) systems was developed in this paper. The heating performance of …

Men's Perspectives On The Impact Of Female-Directed Cash Transfers On Gender Relations: Findings From The Hptn 068 Qualitative Study, Makhosazane Nomhle Khoza, Sinead Delany-Moretlwe, Fiona Scorgie, Jennifer Hove, Amanda Selin, John Imrie, Rhian Twine, Kathleen Kahn, Audrey Pettifor, Catherine L. Mac Phail

Faculty of Social Sciences - Papers (Archive)

HIV is an inherently gendered disease in eastern and southern Africa, not only because more women than men are infected, but also because socially constructed gender norms work to increase women's HIV-infection risk. The provision of cash transfers to young women alone in such a context adds another dimension to already existing complex social relations where patriarchal values are entrenched, gender inequality is the norm, and violence against women and girls is pervasive. It raises concerns about complicating young women's relationships with their male partners or possibly even setting them up for more violence. In our attempt to understand how …

Opioid Use And Harms Associated With A Sustained-Release Tapentadol Formulation: A Postmarketing Study Protocol, Amy Peacock, Briony K. Larance, Michael P. Farrell, Rose Cairns, Nicholas A. Buckley, Louisa Degenhardt

Faculty of Social Sciences - Papers (Archive)

Introduction It has been argued that tapentadol may pharmacologically have lower abuse potential than other pharmaceutical opioids currently available. However, there has been no comprehensive triangulation of data regarding use and harms associated with this formulation. A sustained-release formulation (SRF) of tapentadol (Palexia) was released in Australia in 2011 and listed for public subsidy in 2013. We summarise here the methods of a postmarketing study which will measure postintroduction: (1) population level availability, (2) extramedical use and diversion, (3) attractiveness for extramedical use and (4) associated harms, of tapentadol compared against other pharmaceutical opioids. Methods and analysis We evaluated key …

Island-Hopping Study Shows The Most Likely Route The First People Took To Australia, Kasih Norman

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

The First Australians were among the world's earliest great ocean explorers, undertaking a remarkable 2,000km maritime migration through Indonesia which led to the discovery of Australia at least 65,000 years ago. But the voyaging routes taken through Indonesia's islands, and the location of first landfall in Australia, remain a much debated mystery to archaeologists. Our research, published earlier this year in Quaternary Science Reviews, highlights the most likely route by mapping islands in the region over time through changing sea levels.

Study Of Reaction Sequences During Msr Synthesis Of Tic By Controlled Ball Milling Of Titanium And Graphite, Erhuvwu J. Oghenevweta, David Wexler, Andrzej Calka

Faculty of Engineering and Information Sciences - Papers: Part B

During reactive ball milling of Ti and C, mechanically induced self-propagating reaction (MSR) synthesis of TiC is reported to occur via a process including initial formation of small amounts of TiC prior to exothermic ignition, followed by MSR and the formation of stiochiometric TiC (Dorofeev et al., 2011; Oghenevweta et al., 2016 [1, 2]). However, both the chemical evolution and mechanisms of reaction and growth of TiC both prior to, during and after ignition are not fully understood. This research focuses on fundamental understanding of the reaction sequences during MSR synthesis of TiC from elemental Ti and C (graphite).

Metamorphic Testing Of Navigation Software: A Pilot Study With Google Maps, Joshua Brown, Zhiquan Zhou, Yang-Wai Chow

Faculty of Engineering and Information Sciences - Papers: Part B

Millions of people use navigation software every day to commute and travel. In addition, many systems rely upon the correctness of navigation software to function, ranging from directions applications to self-driving machinery. Navigation software is difficult to test because it is hard or very expensive to evaluate its output. This difficulty is generally known as the oracle problem, a fundamental challenge in software testing. In this study, we propose a metamorphic testing strategy to alleviate the oracle problem in testing navigation software, and conduct a case study by testing the Google Maps mobile app, its web service API, and its …

Chinese Efl Teachers’ Cognition About The Effectiveness Of Genre Pedagogy: A Case Study, Lei-Min Shi, Amanda Ann Baker, Honglin Chen

Faculty of Social Sciences - Papers (Archive)

Developing students’ communicative competence became the primary goal of the current College English Curriculum Requirements in 2004 in China. There has been increasing concern, however, that this goal has yet to be realized, particularly in relation to the teaching of writing. This study investigated the potential of a Systemic Functional Linguistics (SFL-) informed genre approach to enhance Chinese students’ communicative competence in writing. As teachers’ beliefs have a strong impact on the effectiveness of their teaching practice (Borg, 2003), the study examined six Chinese College English teachers’ shifts in their beliefs and practices after attending a training workshop in the …

Faculty of Social Sciences - Papers (Archive)

Issue addressed Only half of Australia's adult population is sufficiently physical active. One method thought to increase incidental physical activity at work is the use of stair‐promoting interventions. Stairs are readily available and stair climbing is considered vigorous physical activity. Motivational signs have been extensively and effectively trialled to increase stair use, but are they suitable for contemporary populations? Methods Participants were occupants of three selected University of Sydney buildings using the elevators or stairs. Infrared people counters were installed to monitor stair and elevator use for 24 h/day during two baseline weeks, followed by two intervention weeks, where motivational …

Activating Primary Care Copd Patients With Multi-Morbidity (Apcom) Pilot Project: Study Protocol, Sameera Ansari, Hassan Hosseinzadeh, Sarah May Dennis, Nicholas Zwar

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

Chronic obstructive pulmonary disease (COPD), third leading cause of mortality worldwide,1 is primarily caused by cigarette smoking in Australia.2 COPD often occurs in the presence of multi-morbidity, which is the simultaneous occurrence of two or more chronic conditions; this is a growing concern in a health system focused on single-disease management.3 Around 80% of older Australians have multi-morbidity, average prevalence of chronic respiratory disease being 9.5%.4 A systematic review of COPD education programs suggests that equipping patients with self-management skills is as important as disease knowledge.5 Studies exploring positive effects of chronic disease-management interventions6 also underline the lack of studies …

Recognition And Management Of Posterior Myocardial Infarction: A Retrospective Cohort Study, Leigh D. White, Joshua Wall, Thomas M. Melhuish, Ruan Vlok, Astin Lee

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

Characteristic electrocardiogram (ECG) features of posterior myocardial infarction (PMI) do not include typical ST-segment elevation and, therefore, carries the risk of delayed diagnosis and management. The aim of this study was to investigate how well PMIs are recognised and whether a lack of recognition translates to a larger infarction. This was a retrospective cohort study of patients sourced from a cardiac catheterisation database. Based on ECG analysis, patients included in this study included those meeting PMI criteria and those meeting ST-elevation myocardial infarction (STEMI) criteria as the control group. Door-to-balloon times were used as an outcome measure for differences in …

Agostinis-Sobrinho, Jorge Mota, Rute Santos, Jorge Enrique Correa-Bautista, Carlos Andres Pena-Guzman, María Andrea Domínguez-Sanchez, Jacqueline Schmidt-Riovalle, Emilio Gonzalez-Jimenez

Faculty of Social Sciences - Papers (Archive)

This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9¿17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls.
