Faculty of Social Sciences - Papers (Archive)

Background Indigenous peoples experience worse health and die at younger ages than their non-indigenous counterparts. Ethnicity data enables health services to identify inequalities experienced by minority populations and to implement and monitor services specifically targeting them. Despite significant Government intervention, Australia's Indigenous peoples, the Aboriginal and Torres Strait Islander peoples, continue to be under identified in data sets. We explored the barriers to Indigenous status identification in urban general practice in two areas in Sydney. Methods A mixed-methods multiple-site case study was used, set in urban general practice. Data collection included semi-structured interviews and self-complete questionnaires with 31 general practice …

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 …

Crime And Victimisation In People With Intellectual Disability: A Case Linkage Study, Billy C. Fogden, Stuart Dm Thomas, Michael D. Daffern, James R. P Ogloff

Faculty of Social Sciences - Papers (Archive)

Background Studies have suggested that people with intellectual disability are disproportionately involved in crime both as perpetrators and victims. Method A case linkage design used three Australian contact-level databases, from disability services, public mental health services and police records. Rates of contact, and official records of victimisation and criminal charges were compared to those in a community sample without intellectual disability. Results Although people with intellectual disability were significantly less likely to have an official record of victimisation and offending overall, their rates of violent and sexual victimisation and offending were significantly higher. The presence of comorbid mental illness considerably …

Faculty of Social Sciences - Papers (Archive)

This paper presents a study of two international doctoral students' perspectives on preparing to formally present the thesis proposal, which we conceptualise as a threshold in the PhD journey. They participated in a thesis writing group (TWG) that aimed to support international doctoral students to develop aspects of their scholarship in the early stages of their candidature. The case students reported feeling 'stuck' before joining the TWG run by the authors. After the writing group experience, they reported that they had gained confidence and developed the skills and knowledge required to prepare for their proposal presentation. Their perspectives were gathered …


Mobilities And The Multinatural: A Test Case In India, Thomas Birtchnell Jan 2016

Mobilities And The Multinatural: A Test Case In India, Thomas Birtchnell

Faculty of Social Sciences - Papers (Archive)

This article examines whether the mobilities paradigm could be more sensitive to recent debates about the more-than-human (animals, plants, and insects) and indeed the inhuman (geological, planetary, and biophysical). Many possible examples spring to mind: the forced movement of people due to "natural" catastrophes, the annual migrations of birds across vast distances, the accidental and intentional spread of invasive weeds. "Multinatural mobilities" are at present both inside and outside of the paradigm's core themes. Can mobilities go beyond transportation, migration, urban development, the hypermobility of the few, and the comparative immobility of the world's majority of people to encompass everything …

Achieving reduction in energy demand is a key directive of the net zero energy building concept. Building designs dedicated to meeting net zero energy building requirements are becoming more commonplace as a path towards reducing the overall emissions from the built environment. This work analyses the energy demand of a net zero energy office building and compares it with a …


Feedback On Second Language Pronunciation: A Case Study Of Eap Teachers' Beliefs And Practices, Amanda Ann Baker, Michael Burri Jan 2016

Feedback On Second Language Pronunciation: A Case Study Of Eap Teachers' Beliefs And Practices, Amanda Ann Baker, Michael Burri

Faculty of Social Sciences - Papers (Archive)

In the modern English language classroom, teachers are often faced with the challenging task of supporting students to achieve comprehensible pronunciation, but many teachers limit or neglect giving students feedback on their pronunciation for a variety of reasons. This paper examines the case of five experienced English for Academic Purposes (EAP) instructors who strive to provide feedback on specific features of pronunciation that negatively affect students' comprehensibility. Results derived from semi-structured interviews, classroom observations and stimulated recall interviews reveal that the teachers use similar approaches to select and provide feedback on problematic features of pronunciation. Naturally, these approaches sometimes differed …

Data collection involved individual interviews immediately before and after the construction in conjunction with analysis of video and audio data collected during the construction process. Before the animation construction, the participants had little understanding of the …


'My Perspective Changed Dramatically': A Case For Preparing L2 Instructors To Teach Pronunciation, Michael Burri Jan 2015

'My Perspective Changed Dramatically': A Case For Preparing L2 Instructors To Teach Pronunciation, Michael Burri

Faculty of Social Sciences - Papers (Archive)

Over the past two decades, pronunciation has slowly regained some of its former prominence in the second language (L2) classroom. Yet, despite this renewed interest, L2 instructors often perceive it to be one of the most challenging areas to teach. Specialists, therefore, suggest that preparing pronunciation teachers is a much needed area in the field of language teaching, but little is known about the education of pronunciation instructors and its potential impact on prospective teachers. This article reports on a qualitative case study in which questionnaires, focus groups, classroom observations and semi-structured interviews were employed to obtain insights on the …

Student Teachers' Cognition About L2 Pronunciation Instruction: A Case Study, Michael Burri Jan 2015

Student Teachers' Cognition About L2 Pronunciation Instruction: A Case Study, Michael Burri

Faculty of Social Sciences - Papers (Archive)

In view of the minimal attention pronunciation teacher preparation has received in second language (L2) teacher education, this study examined the cognition (i.e. beliefs, thoughts, attitudes and knowledge) development of 15 student teachers during a postgraduate subject on pronunciation pedagogy offered at an Australian tertiary institution. Findings revealed that, as a result of taking the subject, student teachers' cognition shifted from teaching individual sounds (i.e. segmentals) to favouring a more balanced approach to pronunciation instruction. That is, teaching the melody of the English language (i.e. suprasegmentals) was seen as important as teaching segmentals. Non-native speakers' self-perceived pronunciation improvement, an increase …


On The Uniqueness Of Lp-Minkowski Problems: The Constant P-Curvature Case In R^3, Yong Huang, Jiakun Liu, Lu Xu Jan 2015

On The Uniqueness Of Lp-Minkowski Problems: The Constant P-Curvature Case In R^3, Yong Huang, Jiakun Liu, Lu Xu

Faculty of Engineering and Information Sciences - Papers: Part A

We study the C4 smooth convex bodies K ⊂Rn+1 satisfying K(x) =u(x)1−p, where x ∈Sn, K is the Gauss curvature of ∂K, u is the support function of K, and p is a constant. In the case of n =2, either when p ∈[−1, 0] or when p ∈(0, 1) in addition to a pinching condition, we show that K must be the unit ball. This partially answers a conjecture of Lutwak, Yang, and Zhang about the uniqueness of the Lp-Minkowski problem in R3. Moreover, we give an explicit pinching constant depending only on p when p ∈(0, 1).

Divergent Approaches To Resolving Pressures On Nrm And Drr Programs: A Case Study Of Sustainable Fire Management Training, Amanda Edwards, Nicholas J. Gill

Faculty of Social Sciences - Papers (Archive)

In the contexts of natural resource management (NRM) and disaster risk reduction (DRR), landholders are increasingly expected to take responsibility for issues which extend beyond property boundaries. Numerous programs are being developed to train landholders to meet these expectations, however the ontological underpinnings, goals and outcomes of these programs can be radically different. Using sustainable fire management as a case study, we compare a modernist approach to training, which educates landholders in the scientific and legislative aspects of NRM and DRR with the aim of persuading them towards particular decisions, with a relational framework which aims to develop new ways …

The Case Studies: Chat In Use - Case Study 13.1 Designing An Effective Undergraduate Vocal Pedagogy Environment: A Case Of Cultural-Historical Activity Approach In A Singing Course, Irina Verenikina, Lotte Latukefu

Faculty of Social Sciences - Papers (Archive)

This chapter draws on six case studies of pedagogy with technology in Higher Education. The studies are chosen because they illustrate how the use of technology impacts on pedagogy in these contexts. While the cases are drawn from different levels of higher education (undergraduate to postgraduate) they are woven together by a shared framework: namely, the use of CHAT to explore pedagogical innovation with technology. One of the significant strengths of CHAT, all studies will argue, lies in its ability to situate goal-directed action within the larger context of a motive-directed activity. That is, its explanatory power lies in situating …
