Extinction risk analysis of exploited green turtle stocks in the Indo-Pacific

In parts of the Indo-Pacific, large-scale exploitation of the green turtle Chelonia mydas continues to pose a serious threat to the persistence of this species; yet very few studies have assessed the pattern and extent of the impact of such harvests. We used demographic and genetic data in an age-based model to investigate the viability of an exploited green turtle stock from Aru, south-east Indonesia. We found that populations are decreasing under current exploitation pressures. The effects of increasingly severe exploitation activities at foraging and nesting habitat varied depending on the migratory patterns of the stock. Our model predicted a rapid decline of the Aru stock in Indonesia under local exploitation pressure and a shift in the genetic composition of the stock. We used the model to investigate the influence of different types of conservation actions on the persistence of the Aru stock. The results show that local management actions such as nest protection and reducing harvests of adult nesting and foraging turtles can have considerable conservation outcomes and result in the long-term persistence of genetically distinct management units. © 2010 The Authors.

The time taken for the regional distribution of ventilation to stabilise: An investigation using electrical impedance tomography

Electrical impedance tomography is a novel technology capable of quantifying ventilation distribution in the lung in real time during various therapeutic manoeuvres. The technique requires changes to the patient’s position to place the electrical impedance tomography electrodes circumferentially around the thorax. The impact of these position changes on the time taken to stabilise the regional distribution of ventilation determined by electrical impedance tomography is unknown. This study aimed to determine the time taken for the regional distribution of ventilation determined by electrical impedance tomography to stabilise after changing position. Eight healthy, male volunteers were connected to electrical impedance tomography and a pneumotachometer. After 30 minutes stabilisation supine, participants were moved into 60 degrees Fowler’s position and then returned to supine. Thirty minutes was spent in each position. Concurrent readings of ventilation distribution and tidal volumes were taken every five minutes. A mixed regression model with a random intercept was used to compare the positions and changes over time. The anterior-posterior distribution stabilised after ten minutes in Fowler’s position and ten minutes after returning to supine. Left-right stabilisation was achieved after 15 minutes in Fowler’s position and supine. A minimum of 15 minutes of stabilisation should be allowed for spontaneously breathing individuals when assessing ventilation distribution. This time allows stabilisation to occur in the anterior-posterior direction as well as the left-right direction.

The eternal return of teaching in the time of the corporation

This article addresses the new conditions under which teachers are making the choice to teach. Our core contention is that the reorganisation of schools according to the logic of the corporation, as described in Deleuze's ‘Postscript’, is changing the flows and forces on the primary surface of ‘the classroom’. These changes block the usual movements of teaching to discipline, normalise and individualise, which was the role of the school as precursor to the factory. Blocked from repeating, or returning, teaching as it has always been done, teachers must actively re-will to teach; teachers cannot use order words to name themselves and direct flows and forces as they have usually been done. While many choices to teach will be undertaken, the most popular being that of choosing to teach toward the corporation, the repetition of teaching toward enclosed spaces becomes less compelling. Like Nietzsche's Zarathustra, teachers, who have the courage to actively choose, face a new dawn in which teaching cannot be what it once was. In that moment they must choose to repeat that choice an infinite number of times, the choice of eternal return, and it is from here that new times might begin.

The logics of good teaching in an audit culture: A Deleuzian analysis

This article examines the attempted reform of education within an emerging audit culture in Australia that has led to the implementation of a high-stakes testing regime known as NAPLAN. NAPLAN represents a machine of auditing, which creates and accounts for data that are used to measure, amongst other things, good teaching. In particular, we address the logics of a policy intervention that aims to improve the quality of education through returning ‘good teaching’. Using Deleuze’s concepts of series, events, copies and simulacra, we suggest that an attempt to return past commonsense logics of ‘good teaching’ as a result of NAPLAN is not possible. In an audit culture as exemplified by NAPLAN, ‘good teaching’ is being reconceptualized through those practices and becomes unrecognizable. Whilst policy claims to improved equity and quality are admirable, this article suggests that the simulacral change to logics of good teaching may actualize something very different.

Breast and prostate cancer survivor responses to group exercise and supportive group Psychotherapy

This study qualitatively examined an 8 week group exercise and counseling intervention for breast and prostate cancer survivors. Groups exercised 3 days per week, 50 minutes per session,performing moderate intensity aerobic and resistance training. Groups also underwent 90 minute supportive group psychotherapy sessions once per week. Survivors discussed their experiences in focus groups post intervention. Transcripts were analyzed using interpretative phenomenological analysis. Survivors described how exercise facilitated counseling by creating mutual aid and trust, and counseling helped participants with self-identity, sexuality, and returning to normalcy. When possible, counselors and fitness professionals should create partnerships to optimally support cancer survivors.

What is racism? Othering, prejudice and hate-motivated violence

The paper’s concern is the current difficulty, in journalism, the academy and politics, of discussing questions to do with race, ethnicity, difference and immigration because of the fear of being called a racist. It starts with an analysis of biographical interview data drawn from fifteen people who had variously acquired the label racist and who were part of a small-scale study into racism in the Midlands city of Stoke-on-Trent, UK conducted between 2003 and 2005. The interviews used the free association narrative interview method. This analysis revealed that most people do not consider themselves racist and that having a conviction for a racially aggravated offence or being a member of a far right organisation was not able to differentiate racists from non-racists. It also revealed a spectrum of attitudes towards immigrants or particular ethnic groups: strong expressions of hatred at one end of the spectrum; strong prejudicial feelings in the middle; and a feeling that ‘outsider’ groups should not benefit at the expense of ‘insiders’ (called ‘othering’) at the other end. The turn to theory for assistance revealed that, although hatred, prejudice and ‘othering’ are not the same thing, and do not have the same origins, they have become elided. This is primarily because cognitive psychology’s hostility to psychoanalysis marginalised hatred whilst its exclusive preoccupation with prejudice came effectively to define racism at the individual level. Progress in thinking about racism might consist of abolishing the term and returning to thinking about hatred, prejudice and ‘othering’ separately.

Psychological consequences of false-positive screening mammograms in the UK

- Objectives To identify the psychological effects of false-positive screening mammograms in the UK. - Methods Systematic review of all controlled studies and qualitative studies of women with a false-positive screening mammogram. The control group participants had normal mammograms. All psychological outcomes including returning for routine screening were permitted. All studies had a narrative synthesis. - Results The searches returned seven includable studies (7/4423). Heterogeneity was such that meta-analysis was not possible. Studies using disease-specific measures found that, compared to normal results, there could be enduring psychological distress that lasted up to 3 years; the level of distress was related to the degree of invasiveness of the assessment. At 3 years the relative risks were, further mammography, 1.28 (95% CI 0.82 to 2.00), fine needle aspiration 1.80 (95% CI 1.17 to 2.77), biopsy 2.07 (95% CI 1.22 to 3.52) and early recall 1.82 (95% CI 1.22 to 2.72). Studies that used generic measures of anxiety and depression found no such impact up to 3 months after screening. Evidence suggests that women with false-positive mammograms have an increased likelihood of failing to reattend for routine screening, relative risk 0.97 (95% CI 0.96 to 0.98) compared with women with normal mammograms. - Conclusions Having a false-positive screening mammogram can cause breast cancer-specific distress for up to 3 years. The degree of distress is related to the invasiveness of the assessment. Women with false-positive mammograms are less likely to return for routine assessment than those with normal ones.

Nine year changes in sitting time in young and mid-aged Australian women: Findings from the Australian longitudinal study for women's health

- Objective To examine changes in sitting time (ST) in women over nine years and to identify associations between life events and these changes. - Methods Young (born 1973–78, n = 5215) and mid-aged (born 1946–51, n = 6973) women reported life events and ST in four surveys of the Australian Longitudinal Study on Women's Health between 2000 and 2010. Associations between life events and changes in ST between surveys (decreasers ≥ 2 h/day less, increasers ≥ 2 h/day more) were estimated using generalized estimating equations. - Results Against a background of complex changes there was an overall decrease in ST in young women (median change − 0.48 h/day, interquartile range [IQR] = − 2.54, 1.50) and an increase in ST in mid-aged women (median change 0.43 h/day; IQR = − 1.29, 2.0) over nine years. In young women, returning to study and job loss were associated with increased ST, while having a baby, beginning work and decreased income were associated with decreased ST. In mid-aged women, changes at work were associated with increased ST, while retiring and decreased income were associated with decreased ST. - Conclusions ST changed over nine years in young and mid-aged Australian women. The life events they experienced, particularly events related to work and family, were associated with these changes.

Sepulchre

The work in Sepulchre (2015) came from my research into female ritual practices and my fascination with specific mythological and historical narratives. These themes were explored during a month-long Summer Residency at Boxcopy Contemporary Artspace. Of particular note were the chronicles and rituals from the terrain around the Adriatic Sea, including Greece and Italy. During the residency, I kept referring to specific mythological texts, which had women as the main protagonists. I kept returning to female characters whose representation was framed by aspects of their sexuality. When looking at these women together, they seemed to sit within a greater narrative archetype, a communal dialogue of shared characteristics, repetitious narrative components and mutual landscapes. Sepulchre became my attempt to develop a conversation between these women by drawing from their commonality, and reimagining these collective elements into sculptural objects and moving images. The video explores an apotropaic gesture, a Baubo-style ‘flashing’. A glass star chart rests on white cliffs, speaking to the narrative of Andromeda and her position as both a celestial and terrene landscape. Another object, a wall mounted copper light burst, pays homage to the framing device used by Gian Lorenzo Bernini in The Ecstasy of Saint Teresa. By reconciling these dialogues, I was interested in exploring expanded portrayals of female sexuality and depictions of subversive and authorial femininity, developed through connotations with mysticism, ritual practice and women’s knowledge.

Documenting the inevitable: Voting behaviour at the 2013 Australian election

This chapter uses data from the 2013 Australian Election Study (AES), conducted by Clive Bean, Ian McAllister, Juliet Pietsch and Rachel Gibson (Bean et al. 2014) to investigate political attitudes and voting behaviour in the election. The study was funded by the Australian Research Council and involved a national survey of political attitudes and behaviour using a self-completion questionnaire mailed to respondents on the day before the 7 September election. The sample was a systematic random sample of enrolled voters throughout Australia, drawn by the Australian Electoral Commission. Respondents were given the option of returning the completed questionnaire by reply-paid mail or completing the survey online. Non-respondents were sent several follow-up mailings and the final sample size was 3955, representing a response rate of 34 per cent. The data were weighted to reflect population parameters for gender, age, state and vote.

Reverie I

Reverie I is a large-scale public art work commissioned by the Brisbane City Council for permanent installation on the Gardens Point Road Plinth adjacent to QUT Gardens Point campus in Brisbane. The work forms part of the artist's ongoing exploration of the methodology of self-portraiture and amorphous form. In this work, sculpted curls of hair have been assembled according to contours of its constituent cast panels - their capacity to nest with one another determined the final form of the work. The resulting mass of curls resembles both an oversized wig, a withered mulberry and a leaden cloud to invoke notions of movement, reflection and temporality. From the didactic panel: "The curls of Reverie I are derived from 18th century sculptural portraiture. The twisting forms of the highly styled wig known as a periwig were abstracted and inventive, while also bestowing an air of intellectual authority. Curls also evoke two aspects of this particular site: the erratic movement of water associated with the complex tidal movements of Brisbane River, and a state of mental reflection relevant to both the nearby university grounds (where intellectual work takes place) and the riverside pathway (a site for daydreaming)."

Catacoustics

'Catacoustics' was an exhibition of sculptural assemblages and photographs that continues my exploration of self-portraiture and the sculptural object. The exhibition was presented as part of the 2015 MetroArts curated exhibition program (Curator: Amy-Clare McCarthy). The work specifically extends the formal vocabulary of my studio practice to incorporate a replica casting of the Ian Fairweather memorial rock at Bribie Island, Queensland. The resulting casts are combined with a series of heptagonal forms derived from the memorial plinth and other sundry components taken from previous exhibitions.,The final arrangement of this diverse field of elements are determined in part by their formal properties (e.g. their capacity to nest, prop, balance, support each other) frequently also taking the horizontal/vertical and the orientation of surrounding walls as formal cues. In so doing, the body of work acts as a manifestation of object-agency. Within this studio methodology, practice is theorised as a site for the interplay of non-human agents. The resulting exhibition thus acts a meditation on the ontology of art practice, conceived as a 'topology' - a fluid network of relationships forged largely by objects.

Warfare in stingless bees

Bees are well known for being industrious pollinators. Some species, however, have taken to invading the nests of other colonies to steal food, nest material or the nest site itself. Despite the potential mortality costs due to fighting with an aggressive opponent, the prospects of a large bounty can be worth the risk. In this review, we aim to bring together current knowledge on intercolony fighting with a view to better understand the evolution of warfare in bees and identify avenues for future research. A review of literature reveals that at least 60 species of stingless bees are involved in heterospecific conflicts, either as attacking or victim colonies. The threat of invasion has led to the evolution of architectural, behavioural and morphological adaptations, such as narrow entrance tunnels, mud balls to block the entrance, decoy nests that direct invaders away from the brood chamber, fighting swarms, and soldiers that are skilled at immobilising attackers. Little is known about how victim colonies are selected, but a phylogenetically controlled analysis suggests that the notorious robber bee Lestrimelitta preferentially attacks colonies of species with more concentrated honey. Warfare among bees poses many interesting questions, including why species differ so greatly in their response to attacks and how these alternative strategies of obtaining food or new nest sites have evolved.
