Fateful moments and the discourses of grief

This paper is concerned with the ways in which language functions in our making sense of death and loss, not only with the use of euphemisms for death, but also the wider discourses which frame meanings and understandings. Many bystanders and commentators on September 11, 2001, for example, likened the impact of the planes on the towers, and their subsequent collapse as “just like a movie ... I couldn’t believe it was happening”. From a culture whose primary experience of death and violence is mediated by film and television, the issue of how these experiences are communicated and understood – by the families of those who died, by the rescue workers and police, by the politicians and the military, and also importantly, by the media and their audiences – is crucial in understanding the ways in which what seem like natural responses are socially and culturally constructed.

There's no place like home : unhomely moments in three postcolonial picture books

One of the principal strands of postcolonial theory and critical practice is the interrogation of received versions of colonial history. This paper investigates the extent to which three contemporary picture books, Gavin Bishop's The House that Jack Built, John Marsden and Shaun Tan's The Rabbits, and Thomas King and William Kent Monkman's A Coyote Columbus Story, mobilise postcolonial strategies in their representations of place. In particular, it focuses on how postcolonial textuality unsettles and transgresses notions of "homeliness" in narratives involving the displacement of colonised and colonising peoples. As the shifting power relations of colonialism render unhomely what has previously been homely (especially for colonised peoples), so they involve a contrary move in which unhomely spaces are changed into simulacra of lost or abandoned homes. Drawing upon Walter Benjamin's formulation of materialist historiography, Homi Bhabha describes what he terms 'the unhomely moment' as that in which personal and psychic histories intersect with the violent dislocations of colonialism. This paper will argue that such unhomely moments shape the visual and verbal narratives of The House that Jack Built, The Rabbits and A Coyote Columbus Story, all of which deal with the trauma which occurs when cultures previously geographically and psychically distant are brought into close contact with each other. Written to and for children who are citizens of postcolonial cultures, these texts disclose the unease which persists in contemporary societies where colonial histories are rehearsed and revisioned. However, the paper will argue that the three texts position readers in quite different ways; for instance, while the verbal text of The Rabbits constructs an implied author capable of speaking for the colonised and offering readers a very circumscribed subject position, Thomas King's narrative in A Coyote Columbus Story engages in a dialogic playfulness which allows readers to adopt a variety of reading positions. For each text, some key representations of unhomely moments will be considered, and the paper will explore the extent to which they construct forms of temporality which negotiate the space between history and its significances within crosscultural and intercultural formations.

Non-smooth optimization methods for computation of the conditional value-at-risk and portfolio optimization

We examine numerical performance of various methods of calculation of the Conditional Value-at-risk (CVaR), and portfolio optimization with respect to this risk measure. We concentrate on the method proposed by Rockafellar and Uryasev in (Rockafellar, R.T. and Uryasev, S., 2000, Optimization of conditional value-at-risk. Journal of Risk, 2, 21-41), which converts this problem to that of convex optimization. We compare the use of linear programming techniques against a non-smooth optimization method of the discrete gradient, and establish the supremacy of the latter. We show that non-smooth optimization can be used efficiently for large portfolio optimization, and also examine parallel execution of this method on computer clusters.

The ultrasound appearance of the patellar tendon attachment to the tibia in young athletes is conditional on gender and pubertal stage

This cross-sectional study investigated the imaging appearance of the previous termpatellarnext term tendon attachment to the tibia in young male and female tennis players of different ages and pubertal status. Forty-four competitive young players, who had been playing tennis at least for 2 years, were recruited from a tennis school and local tennis clubs. All subjects had bilateral ultrasound imaging of the previous termpatellarnext term tendon attachment to the tibia. Standard anthropometric measurements, pubertal status and injury history were recorded. Ultrasound appearance of the previous termpatellarnext term tendon attachment was categorised into three stages: cartilage attachment, insertional cartilage and mature attachment. Cartilage attachment was more prevalent in boys (32%) and extended further into puberty (until Tanner stage 4) compared to girls (6% and Tanner stage 1). Tendons with Osgood–Schlatter Disease symptoms (n = 3) did not have a cartilage attachment. Imaging appearance commonly seen in young active athletes, consistent with a clinical diagnosis of OSD, was more common in boys and in the pre- and peri-pubertal stages.

Parametric conditional frailty models for recurrent cardiovascular events in the lipid study

Background Analysis of recurrent event data is frequently needed in clinical and epidemiological studies. An important issue in such analysis is how to account for the dependence of the events in an individual and any unobserved heterogeneity of the event propensity across individuals.Methods We applied a number of conditional frailty and nonfrailty models in an analysis involving recurrent myocardial infarction events in the Long-Term Intervention with Pravastatin in Ischaemic Disease study. A multiple variable risk prediction model was developed for both males and females. Results A Weibull model with a gamma frailty term fitted the data better than other frailty models for each gender. Among nonfrailty models the stratified survival model fitted the data best for each gender. The relative risk estimated by the elapsed time model was close to that estimated by the gap time model. We found that a cholesterol-lowering drug, pravastatin (the intervention being tested in the trial) had significant protective effect against the occurrence of myocardial infarction in men (HR¼0.71, 95% CI0.60–0.83). However, the treatment effect was not significant in women due to smaller sample size (HR¼0.75, 95% CI 0.51–1.10). There were no significant interactions between the treatment effect and each recurrent MI event (p¼0.24 for men and p¼0.55 for women). The risk of developing an MI event for a male who had an MI event during follow-up was about 3.4 (95% CI 2.6–4.4) times the risk compared with those who did not have an MI event. The corresponding relative risk for a female was about 7.8 (95% CI 4.4–13.6). Limitations The number of female patients was relatively small compared with their male counterparts, which may result in low statistical power to find real differences in the effect of treatment and other potential risk factors.Conclusions The conditional frailty model suggested that after accounting for all the risk factors in the model, there was still unmeasured heterogeneity of the risk for myocardial infarction, indicating the effect of subject-specific risk factors. These risk prediction models can be used to classify cardiovascular disease patients into different risk categories and may be useful for the most effective targeting of preventive therapies for cardiovascular disease.

A conditional probability approach to risk assessment for child sexual offenders with different classes of victim

Specific scales were developed for discriminating child sexual offenders with different classes of victim. The project demonstrates a method of individualising scores on actuarial risk assessment measured in a way that makes them more meaningful for those involved in decision-making about individual child sexual offenders. At present, the only quantifiable approach to specific decision-making relies on a general prediction of future behaviour, based on group data. The Bayesian approach is one method that can be used to assist decision-makers to use this information in ways that lead to the more appropriate management of risk. Ultimately, the better management of known child sexual offenders will lead to fewer offences and a reduction in the number of children who lives are profoundly affected by sexual victimisation.

Defining moments in men's lives : a study of personal narratives

This study explores the defining moments in six men’s lives. The empirical dimension of the research is built around the personal narratives these men tell of their lives across a series of four interviews. The central research theme is the notion of the defining moment as a key element in the processes of establishing how men understand and interpret the events and incidents that have shaped their lives. In the context of this study, the defining moment is seen as the moment or period in time when an individual gives definition to a specific event or experience, as a transition point with (potentially) life-altering consequences. Some of the thematic structures presented include relationships with significant adults (parents, teachers), masculinity, self-harm, schooling, mental illness, isolation, loneliness, stress and relationships with peers. In my pursuit of a methodology that could accommodate the aims of this study, I explored the process of meaning through the qualitative paradigm. Drawing on the principles of qualitative research, as applied through narrative inquiry, I deployed a semi-structured interview format to collect the lived experiences of participants. By privileging the stories that individuals tell of their experiences, the narrative method recognises that data are inexorably located in the contextual and contingent. The experiences and narratives that are presented in this thesis are built around the authentic voices of participants. The study presents a warrant for working with men’s defining moments to disrupt, alter and redefine their attitudes and behaviours in order to improve their lives. Based on the insights gleaned through this study, I argue that there are defining times/points in people’s lives where their experiences can be life altering. When these experiences involve uncertainty, anxiety, stress and other pernicious effects, their longer-term consequences can be devastating. The study confirms existing research, that men are reluctant to seek help or reveal their insecurities during such times, therefore making them particularly vulnerable to defining moments. The conclusion of this thesis establishes some broad recommendations pertaining to working effectively with men and their defining moments. I focus particular attention on the place of schooling and education in helping individuals recognise and respond to the early symptoms of what is potentially a life-altering experience. Schools and, by association, teachers need to be actively and strategically involved in this process. To this end, I argue the need for targeted interventions that are both sensitive and timely. In their engagements with young males, parents, teachers, coaches and mentors need to be particularly attuned to their silent screams for help.

An examination of conditional asset pricing models in the Australian equities market

This article examines the link between macroeconomic variables and equity returns in Australia by testing conditional asset pricing models. We find that conditioning the Fama-French model with a series of macroeconomic variables does not considerably improve its performance. However, we do find that the Fama-French factors, SMB and HML, retain their ability to explain equity returns even after the model is conditioned on macroeconomic variables. Our findings suggest that investors do not adjust their risk premiums according to the changes in the macroeconomic variables we employ.
