Two trees: Australian artists' books to Afghanistan and back

Two Trees documents an artists' books collaboration between 14 Australian women artists and women in Afghanistan who were learning literacy. The collaboration resulted in 36 concertina books of images, withDari and Pashto hand written texts.The books are held in the State Library of Queensland's artists' books collection. Two Trees includes includes an introduction by Barbara Kameniar, and texts by Malalai Joya, Gali Weiss, Matthias Thomczak and Latifa Ahmady.

'I've been to Bali too' (and I will be going back) : are terrorist shocks to Bali's tourist arrivals permanent or transitory?

International visitor arrivals to Bali are examined using univariate and panel Lagrange multiplier (LM) unit root tests with one and two structural breaks to ascertain if shocks to the time path of tourist arrivals are permanent or transitory. The univariate LM unit root tests with one and two structural breaks fail to reject the null hypothesis of a unit root in international visitor arrivals to Bali. However, the panel LM unit root tests with one and two structural breaks applied to a panel of Bali's 11 major source markets reject the null and support the alternative hypothesis of a joint trend-stationary series with transitory shocks. This result suggests that, the effects of the recent terrorist acts on Bali on the growth path of tourist arrivals from major markets are only transitory and that as a consequence Bali's tourism sector is sustainable in the long run.

Barriers to primary care clinician adherence to clinical guidelines for the management of low back pain: protocol of a systematic review and meta-synthesis of qualitative studies.

INTRODUCTION: Low back pain is the highest ranked condition contributing to years lived with disability, and is a significant economic and societal burden. Evidence-based clinical practice guidelines are designed to improve quality of care and reduce practice variation by providing graded recommendations based on the best available evidence. Studies of low back pain guideline implementation have shown no or modest effects at changing clinical practice. OBJECTIVES: To identify enablers and barriers to adherence to clinical practice guidelines for the management of low back pain. METHODS AND ANALYSIS: A systematic review and meta-synthesis of qualitative studies that will be conducted and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement guidelines. Eight databases will be searched using a priori inclusion/exclusion criteria. Two independent reviewers will conduct a structured review and meta-synthesis, and a third reviewer will arbitrate where there is disagreement. This protocol has been registered on PROSPERO 2014. ETHICS AND DISSEMINATION: Ethical approval is not required. The systematic review will be published in a peer-reviewed journal. The review will also be disseminated electronically, in print and at conferences. Updates of the review will be conducted to inform and guide healthcare translation into practice.

Altered response of the anterolateral abdominal muscles to simulated weight-bearing in subjects with low back pain

An important aspect of neuromuscular control at the lumbo-pelvic region is stabilization. Subjects with low back pain (LBP) have been shown to exhibit impairments in motor control of key muscles which contribute to stabilization of the lumbo-pelvic region. However, a test of automatic recruitment that relates to function has been lacking. A previous study used ultrasound imaging to show that healthy subjects automatically recruited the transversus abdominis (TrA) and internal oblique (IO) muscles in response to a simulated weight-bearing task. This task has not been investigated in subjects with LBP. The aim of this study was to compare the automatic recruitment of the abdominal muscles among subjects with and without LBP in response to the simulated weight-bearing task. Twenty subjects with and without LBP were tested. Real-time ultrasound imaging was used to assess changes in thickness of the TrA and internal oblique IO muscles as well as lateral movement ("slide") of the anterior fascial insertion of the TrA muscle. Results showed that subjects with LBP showed significantly less shortening of the TrA muscle (P < 0.0001) and greater increases in thickness of the IO muscle (P = 0.002) with the simulated weight-bearing task. There was no significant difference between groups for changes in TrA muscle thickness (P = 0.055). This study provides evidence of changes in motor control of the abdominal muscles in subjects with LBP. This test may provide a functionally relevant and non-invasive method to investigate the automatic recruitment of the abdominal muscles in people with and without LBP.

The sexual motivation of boars housed adjacent to ovariectomised gilts did not affect the efficiency of detecting hormonally induced oestrus using the back pressure test

This study tested the hypothesis that the efficiency of detecting oestrus in gilts, using the back pressure test (BPT), will be reduced when gilts are housed adjacent to a boar of high sexual motivation compared to when gilts are housed adjacent to a boar of low sexual motivation. The experiment was a 2 x 2 Latin square design with three replicates. Boars of high and low sexual motivation were selected on the basis of the total number of copulations and the mean reaction time to first mount during three mating tests. Twelve boars were observed in mating tests and the three highest and lowest ranking boars were assigned to three palm, each pair containing a boar of high and a boar of low sexual motivation. One pair was used in each replicate. In each replicate, two groups of six ovariectomised gilts were housed for 14 days, commencing 7 days prior to hormonally induced destrus, adjacent to a boar of either high or low sexual motivation. All gilts were checked twice daily for oestrus using the BPT. In the first replicate, the level of proceptive behaviour of the gilts was quantified immediately after checking for oestrus in a 3-rain test in which the amount of time that the gilts spent within 0.5 m of a pen containing a sexually mature boar was recorded. There were no effects of housing gilts adjacent to boars of high or low sexual motivation on the percentage of gilts detected in oestrus, the percentage of gilts detected in oestrus for more than I day, the duration of oestrus or the level of proceptive behaviour of gilts. These data suggest that the level of sexual motivation of boars does not influence the efficiency of detecting hormonally induced oestrus, using the BPT, in ovariectomised gilts housed adjacent to boars.

Barriers to primary care clinician adherence to clinical guidelines for the management of low back pain: a systematic review and meta-synthesis of qualitative studies

INTRODUCTION: Despite the availability of evidence-based guidelines for the management of low back pain that contain consistent messages, large evidence-practice gaps in primary care remain.

OBJECTIVES: To perform a systematic review and meta-synthesis of qualitative studies that have explored primary care clinicians' perceptions and beliefs about guidelines for low back pain, including perceived enablers and barriers to guideline adherence.

METHODS: Studies investigatingperceptions and beliefs about low back pain guidelines were included if participants were primary care clinicians and qualitative methods had been used for both data collection and analysis. We searched major databases up to July 2014. Pairs of reviewers independently screened titles and abstracts, extracted data, appraised method quality using the CASP checklist, conducted thematic analysis and synthesized the results in narrative format.

RESULTS: Seventeen studies, with a total of 705 participants, were included. We identified three key emergent themes and eight subthemes: (1) guideline implementation and adherence beliefs and perceptions; (2) maintaining the patient-clinician relationship with imaging referrals; (3) barriers to guideline implementation. Clinicians believed that guidelines were categorical, prescriptive and constrained professional practice; however popular clinical practices superseded the guidelines. Imaging referrals were used to manage consultations and to obtain definitive diagnoses. Clinicians' perceptions reflected a lack of content knowledge and understanding of how guidelines are developed.

DISCUSSION: Addressing misconceptions and other barriers to uptake of evidence-based guidelines for managing low back pain is needed to improve knowledge transfer and close the evidence-practice gap in the treatment of this common condition.

Clinical reasoning sessions: back to the patient

BACKGROUND: Problem-based learning (PBL) was developed as a facilitated small group learning process based around a clinical problem. Originally designed for pre-clinical years of medical education, its application across all years poses a number of difficulties, including the risk of reducing patient contact, providing a learning process that is skewed towards an understanding of pathophysiological processes, which may not be well understood in all areas of medicine, and failing to provide exposure to clinically relevant reasoning skills. CONTEXT: Curriculum review identified dissatisfaction with PBLs in the clinical years of the Sydney Medical School's Graduate Medical Program, from both staff and students. A new model was designed and implemented in the Psychiatry and Addiction Medicine rotation, and is currently being evaluated. INNOVATION: We describe an innovative model of small-group, student-generated, case-based learning in psychiatry - clinical reasoning sessions (CRS) - led by expert facilitators. IMPLICATIONS: The CRS format returns the student to the patient, emphasises clinical assessment skills and considers treatment in the real-world context of the patient. Students practise a more sophisticated reasoning process with real patients modelled upon that of their expert tutor. This has increased student engagement compared with the previous PBL programme.

Looking back to move forward: the Dymaxion revisited

In 1933 and 1934 the visionary architect, designer, engineer and philosopher Robert Buckminster Fuller built three prototypes of a car he named the Dymaxion. Regarded as a ground breaking concept vehicle, the Dymaxion is arguably more relevant today than when it was conceived over eighty years ago. Although plans to manufacture were abandoned by Chrysler in 1933, the Dymaxion Car was considered the most fuel-efficient car of its time using less than half the amount of gasoline than any other car on the road. This was due to its meticulous design based on scientific first principles, power weight ratios and the laws of aerodynamics. The Dymaxion was spacious and easy to maneuver; it offered multi purpose use options with the passenger capacity of a modern people carrier and represented Buckminster Fuller's social responsibility mantra to create more with less. The brand narrative of the Dymaxion tells a story of sustainability and practicality that resonates with today's vehicle consumer market. The adage suggesting that there is reason why a car's windshield is bigger than its rear view mirror and implies that what lies ahead is much more important than anything behind you. Although this life metaphor acknowledges the importance of an occasional glace back this paper emphasises the strategic value of a precognitive, retrospective approach to design.

Deformation field variations in equal channel angular extrusion due to back pressure

Flow lines were analysed in aluminium alloy 6061 during equal channel angular extrusion (ECAE) in a 90° die with and without the application of back pressure during pressing. The lines appeared much more rounded when a back pressure was applied compared to the case of conventional ECAE testing. With the help of an analytic flow function, the deformation field was obtained. It is shown that back pressure slightly lowers the total strain, strongly increases the size of the plastic zone and significantly reduces the plastic strain rate.

Back to the future: Warlpiri encounters with drawings, country and others in the digital age

Since the early 1900s, Warlpiri people living in the central desert region of Australia have experienced an intense process of adaption to the changing circumstances of postcolonial life. From the earliest days, their encounters with kardiya, non-Aboriginal people, have been mediated by diverse visual technologies that have, over time, become integral to the ways Warlpiri orient themselves to each other and their wider world. In this paper I trace the key elements of the complex visual environment that has emerged from this history of mediation. The central part of the paper considers events around the repatriation to Warlpiri communities in 2011 of a collection of drawings made in the 1950s by their forebears.In responses to a medium that once was new but now is old, several points of interest emerge, among them a clear sense of a hierarchy of value Warlpiri apply to modes of visual communication. In the context of the return of the drawings, the significance Warlpiri ascribe to other visual media comes to the fore. I consider some of the ways visual forms are deployed in support of public projections of cultural identity on the one hand and everyday modes of expression and address on the other. The paper’s central argument is that contemporary Warlpiri attitudes to images – whether they be drawn, painted or broadcast – reveal the complex postcolonial workings of mimetic desire.
