A fish out of water? Legal practitioner - practitioner teacher? Bourdieu, the legal field and the scholarship of teaching in practical legal training

It is surprising to discover during early doctoral research that there is a paucity of Australian scholarship using Bourdieu’s theoretical tools in the field of law, and in the sub-field of post-graduate pre-admission practical legal training. This article introduces Bourdieu’s conceptions of habitus, field, categories of capital, symbolic violence, and misrecognition. It describes how Bourdieu applied these tools to identify structural hostility between legal academics and practitioners, and the struggles for control in the field of law. Review of three North American studies that used Bourdieu’s theories follows, involving law students’ habitus in transition, class stratification in legal education, and gender stratification in law firm partnerships. Drawing on three internally connected ‘moments’ necessary to use Bourdieu’s tools, together with four critical questions concerning teachers’ engagement with the scholarship of teaching, this article identifies new questions for investigation. These questions will frame further research to discover whether the objective structures of the practical legal training field and the habitus of legal practitioners constrains them to act as ‘fish out of water’ in the context of a scholarship of teaching.

'Catastrophic failure' theories and disaster journalism : evaluating media explanations of the Black Saturday bushfires

 In recent decades, academic researchers of natural disasters and emergency management have developed a canonical literature on ‘catastrophe failure’ theories such as disaster responses from US emergency management services (Drabek, 2010; Quarantelli, 1998) and the Three Mile Island nuclear power plant (Perrow, 1999). This article examines six influential theories from this field in an attempt to explore why Victoria’s disaster and emergency management response systems failed during Australia’s Black Saturday bushfires. How well, if at all, are these theories understood by journalists, disaster and emergency management planners, and policy-makers? In examining the Country Fire Authority’s response to the fires, as well as the media’s reportage of them, we use the 2009 Black Saturday bushfires as a theory-testing case study of failures in emergency management, preparation and planning. We conclude that journalists can learn important lessons from academics’ specialist knowledge about disaster and emergency management responses.

Visual sensitivity loss in the central 30° of visual field is associated with diabetic peripheral neuropathy

Aims/hypothesis
Impaired central vision has been shown to predict diabetic peripheral neuropathy (DPN). Several studies have demonstrated diffuse retinal neurodegenerative changes in diabetic patients prior to retinopathy development, raising the prospect that non-central vision may also be compromised by primary neural damage. We hypothesise that type 2 diabetic patients with DPN exhibit visual sensitivity loss in a distinctive pattern across the visual field, compared with a control group of type 2 diabetic patients without DPN.

Methods
Increment light sensitivity was measured by standard perimetry in the central 30° of visual field for two age-matched groups of type 2 diabetic patients, with and without neuropathy (n = 40/30). Neuropathy status was assigned using the neuropathy disability score. Mean visual sensitivity values were calculated globally, for each quadrant and for three eccentricities (0–10°, 11–20° and 21–30°). Data were analysed using a generalised additive mixed model (GAMM).

Results
Global and quadrant between-group visual sensitivity mean differences were marginally but consistently lower (by about 1 dB) in the neuropathy cohort compared with controls. Between-group mean differences increased from 0.36 to 1.81 dB with increasing eccentricity. GAMM analysis, after adjustment for age, showed these differences to be significant beyond 15° eccentricity and monotonically increasing. Retinopathy levels and disease duration were not significant factors within the model (p = 0.90).

Conclusions/interpretation
Visual sensitivity reduces disproportionately with increasing eccentricity in type 2 diabetic patients with peripheral neuropathy. This sensitivity reduction within the central 30° of visual field may be indicative of more consequential loss in the far periphery.

Identification of prey captures in Australian Fur Seals (Arctocephalus pusillus doriferus) using head-mounted accelerometers: field validation with animal-borne video cameras

This study investigated prey captures in free-ranging adult female Australian fur seals (Arctocephalus pusillus doriferus) using head-mounted 3-axis accelerometers and animal-borne video cameras. Acceleration data was used to identify individual attempted prey captures (APC), and video data were used to independently verify APC and prey types. Results demonstrated that head-mounted accelerometers could detect individual APC but were unable to distinguish among prey types (fish, cephalopod, stingray) or between successful captures and unsuccessful capture attempts. Mean detection rate (true positive rate) on individual animals in the testing subset ranged from 67-100%, and mean detection on the testing subset averaged across 4 animals ranged from 82-97%. Mean False positive (FP) rate ranged from 15-67% individually in the testing subset, and 26-59% averaged across 4 animals. Surge and sway had significantly greater detection rates, but also conversely greater FP rates compared to heave. Video data also indicated that some head movements recorded by the accelerometers were unrelated to APC and that a peak in acceleration variance did not always equate to an individual prey item. The results of the present study indicate that head-mounted accelerometers provide a complementary tool for investigating foraging behaviour in pinnipeds, but that detection and FP correction factors need to be applied for reliable field application.

Theories into practice: understanding and rethinking our work with young children and the EYLF

This book introduces and explores each of the five major groups of theories described in the Early Years Learning Framework that inform practice in the early childhood field. In doing so, it addresses the need of the early childhood educators to better understand how their practice is underpinned by theories of learning and development.Educators draw from a range of perspectives, but it can sometimes be difficult to understand the link between theorists, theories and perspectives and their own practice. This book makes these links clear and easy to understand so educators can talk with more authority to colleagues, families and communities about their work, and reflect constructively on their practice.Each chapter deals with a different group of theories, briefly outlining the major thrust of each group and what it might look like in practice. Some of the major theorists are then focused on in turn. Discussion starter topics follow each theorist to promote discussion on the main topics and threads of the theorist’s thinking. This is followed by questions for reflection that relate more to thinking about the main concepts in relation to practice.

Evaluation of the Test-mate ChE (cholinesterase) field kit in acute organophosphorus poisoning

STUDY OBJECTIVE: Measurement of acetylcholinesterase (AChE) is recommended in the management of organophosphorus poisoning, which results in 200,000 deaths worldwide annually. The Test-mate ChE 400 is a portable field kit designed for detecting occupational organophosphorus exposure that measures RBC AChE and plasma cholinesterase (PChE) within 4 minutes. We evaluate Test-mate against a reference laboratory test in patients with acute organophosphorus self-poisoning. METHODS: This was a cross-sectional comparison study of 14 patients with acute organophosphorus poisoning between May 2007 and June 2008. RBC AChE and PChE were measured in 96 and 91 samples, respectively, with the Test-mate ChE field kit and compared with a reference laboratory, using the limits of agreement method (Bland and Altman), κ statistics, and Spearman's correlation coefficients. RESULTS: There was good agreement between the Test-mate ChE and the reference laboratory for RBC AChE. The mean difference (Test-mate-reference) was -0.62 U/g hemoglobin, 95% limits of agreement -10.84 to 9.59 U/g hemoglobin. Good agreement was also observed between the categories of mild, moderate, and severe RBC AChE inhibition (weighted κ 0.85; 95% confidence interval [CI] 0.83 to 0.87). Measurement of PChE also showed good agreement, with a mean difference (Test-mate-reference) of +0.06 U/mL blood, 95% limits of agreement -0.41 to 0.53 U/mL blood. Spearman's correlation coefficients were 0.87 (95% CI 0.81 to 0.91) for RBC AChE and 0.76 (95% CI 0.66 to 0.84) for PChE. Analysis for within-subject correlation of subjects did not change the limits of agreement. CONCLUSION: The Test-mate ChE field kit reliably provides rapid measurement of RBC AChE in acute organophosphorus poisoning.
