Imagine, Interrupt, Innovate: Internationalising Teaching and Learning Practice

Internationalisation of the curriculum is a key research area at the intersection of teaching and learning. Increasing numbers of international students in Australian schools and tertiary institutions necessitate the reconceptualisation of curriculum to incorporate global perspectives and develop intercultural competencies of both students and teachers. Accordingly, this research project identified key discipline areas at Avondale College of Higher Education in which to perform pedagogical intervention with an internationalisation focus. Three lecturers undertook action research in the areas of Primary Education, Business and Theology, resulting in the production of culturallyinformed perspectives, increased cross-cultural awareness and the identification of areas for future research and innovation

The value of eye-tracking technology in the analysis and interpretations of skeletal remains: A pilot study

This initial study is the first to use eye-trackers as a tool in order to study gaze pattern strategies and decision making processes involved in the assessment of skeletal remains. Three experienced participants were asked to wear eye-tracking glasses (Tobii Pro Glasses 2) when estimating sex and age-at-death of one set of skeletal remains from a known archeological sample. The study assessed participants' fixation points (the features of the skeleton focused on), fixation duration (the total time spent on each assessment and feature) as well as visit count and duration (the total number of visits and the duration of visits to particular areas). The preliminary results of this study identified differences in gaze “strategies” with regards to fixation points, visit duration, and visit counts between the participants. The data generated provide a starting point for assessing how such technologies could be used in order to more fully understand the decision making processes involved in forensic anthropological interpretations and their role in forensic reconstructions

Spatial distribution of stars and brown dwarfs in sigma Orionis

I have re-visited the spatial distribution of stars and high-mass brown dwarfs in the sigma Orionis cluster (~3 Ma, ~360 pc). The input was a catalogue of 340 cluster members and candidates at separations less than 30 arcmin to sigma Ori AB. Of them, 70 % have features of extreme youth. I fitted the normalised cumulative number of objects counting from the cluster centre to several power-law, exponential and King radial distributions. The cluster seems to have two components: a dense core that extends from the centre to r ~ 20 arcmin and a rarified halo at larger separations. The radial distribution in the core follows a power-law proportional to r^1, which corresponds to a volume density proportional to r^(-2). This is consistent with the collapse of an isothermal spherical molecular cloud. The stars more massive than 3.7 Msol concentrate, however, towards the cluster centre, where there is also an apparent deficit of very low-mass objects (M < 0.16 Msol). Last, I demonstrated through Monte Carlo simulations that the cluster is azimuthally asymmetric, with a filamentary overdensity of objects that runs from the cluster centre to the Horsehead Nebula.Comment: MNRAS, accepte

Parental behaviour in paediatric chronic pain: A qualitative observational study

Parental behaviour appears to influence the adjustment of children with chronic pain. However, research in this area has failed to produce consistent evidence. Studies have tended to rely on self-report measures derived from adult pain populations. This qualitative, observational research provides descriptive data of parental behaviour in a clinical environment. A qualitative observational study was made of parents and adolescents in a physically stressful setting. Modified grounded theory was used to analyse verbal and non-verbal behaviours. Eight parent–adolescent dyads seeking treatment for chronic pain were videoed during physical exercise sessions. Verbal and non-verbal behaviours were recorded and transcribed. Four overarching categories emerged: ‘monitoring’, ‘protecting’, ‘encouraging’ and ‘instructing’. These often had both verbal and non-verbal aspects. Within these categories, more precise behavioural groups were also identified. This research identifies categories of parental behaviour that were derived directly from observation, rather than imposed on the basis of results from different populations. Four categories of behaviour were derived, which clarify and extend dimensions used in existing self-report instruments. Careful description of parental behaviours showed features that past research has neglected, and highlighted potential drawbacks of apparently positive parental actions

Extraordinary consumer experiences: Why immersion and transformation cause trouble

Author's accepted version (postprint).This is the peer reviewed version of the following article: Lindberg, F. and Østergaard, P. (2015). Extraordinary consumer experiences: Why immersion and transformation cause trouble. Journal of Consumer Behaviour, which has been published in final form at http://dx.doi.org/10.1002/cb.1516. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving (http://olabout.wiley.com/ WileyCDA/Section/id-820227.html).This paper presents and discusses how consumers are transformed in and out of immersion during extraordinary, long-lasting wilderness canoeing experiences. Based on a hermeneutic multi-phase empirical approach, we show how extraordinary experiences can be dynamic, multifaceted, and emergent. The positive connotations of prior research are questioned as we find that consumers face various paradoxes and ambiguities throughout the various consumption phases. While a major part of research today focuses on the co-creation efforts of consumers when they combine various on-site resource of experiencescapes, our findings point to the importance of understanding consumer resources. The distinction held between the ordinary and the extraordinary does not hold within the present context, and we discuss how role conflicts may influence transformation and immersion during consumption of experiences

MSV3d: database of human MisSense variants mapped to 3D protein structure

The elucidation of the complex relationships linking genotypic and phenotypic variations to protein structure is a major challenge in the post-genomic era. We present MSV3d (Database of human MisSense Variants mapped to 3D protein structure), a new database that contains detailed annotation of missense variants of all human proteins (20 199 proteins). The multi-level characterization includes details of the physico-chemical changes induced by amino acid modification, as well as information related to the conservation of the mutated residue and its position relative to functional features in the available or predicted 3D model. Major releases of the database are automatically generated and updated regularly in line with the dbSNP (database of Single Nucleotide Polymorphism) and SwissVar releases, by exploiting the extensive Décrypthon computational grid resources. The database (http://decrypthon.igbmc.fr/msv3d) is easily accessible through a simple web interface coupled to a powerful query engine and a standard web service. The content is completely or partially downloadable in XML or flat file formats

Disks in the Arches cluster -- survival in a starburst environment

Deep Keck/NIRC2 HK'L' observations of the Arches cluster near the Galactic center reveal a significant population of near-infrared excess sources. We combine the L'-band excess observations with K'-band proper motions, to confirm cluster membership of excess sources in a starburst cluster for the first time. The robust removal of field contamination provides a reliable disk fraction down to our completeness limit of H=19 mag, or about 5 Msun at the distance of the Arches. Of the 24 identified sources with K'-L' > 2.0 mag, 21 have reliable proper motion measurements, all of which are proper motion members of the Arches cluster. VLT/SINFONI K'-band spectroscopy of three excess sources reveals strong CO bandhead emission, which we interpret as the signature of dense circumstellar disks. The detection of strong disk emission from the Arches stars is surprising in view of the high mass of the B-type main sequence host stars of the disks and the intense starburst environment. We find a disk fraction of 6 +/- 2% among B-type stars in the Arches cluster. A radial increase in the disk fraction from 3 to 10% suggests rapid disk destruction in the immediate vicinity of numerous O-type stars in the cluster core. A comparison between the Arches and other high- and low-mass star-forming regions provides strong indication that disk depletion is significantly more rapid in compact starburst clusters than in moderate star-forming environments.Comment: 51 pages preprint2 style, 22 figures, accepted by Ap

Selenium supplementation and insulin resistance in a randomized, clinical trial

Objective: While controversial, observational and randomized clinical trial data implicate the micronutrient selenium (Se) in the development of type 2 diabetes (T2D). The aim of this study was to test the hypothesis that Se supplementation adversely affects pancreatic beta-cell function and insulin sensitivity. Research design and methods: In a subset of 400 individuals participating in a randomized, placebocontrolled trial of Se at 200 mu g/day for colorectal adenomatous polyps, fasting plasma glucose and insulin were measured before randomization and within 6 months of completing intervention. Change in the homeostasis model assessment-beta cell function (HOMA2-%beta) and insulin sensitivity (HOMA2-%S) were compared between arms. A subgroup of 175 (79 Se and 96 placebo) participants underwent a modified oral glucose tolerance test (mOGTT) at the end of intervention and change in glucose values was assessed. Results: No statistically significant differences were observed for changes in HOMA2-%beta or HOMA2-%S between those who received Se compared with placebo. After a mean of 2.9 years on study, mean HOMA2-%beta values were 3.1 +/- 24.0 and 3.1 +/- 29.8 for the Se and placebo groups, respectively (p=0.99). For HOMA2-%S, the values were -0.5 +/- 223.2 and 80.9 +/- 1530.9 for the Se and placebo groups, respectively (p=1.00). Stratification by sex or age did not reveal any statistically significant effects on insulin sensitivity by treatment group. For mOGTT, mean baseline fasting blood glucose concentrations were significantly higher among participants in the placebo group compared with the Se group (96.6 +/- 14.6 and 92.3 +/- 12.0, respectively; p=0.04), a trend which remained through the 20 min assessment. Conclusions: These findings do not support a significant adverse effect of daily Se supplementation with 200 mu g/day of selenized yeast on beta-cell function or insulin sensitivity as an explanation for previously reported associations between Se and T2D. Further clarification of longer term effects of Se is needed.National Cancer Institute Cancer Center Support Grant [P30 CA023074]; NIH/NCI [R01CA151708, P01 CA041108]; NIH [R01DK047396]Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
