Aim: Climate change is expected to increase the frequency and intensity of extreme climatic events, such as severe droughts and intense rainfall periods. We explored how the avifauna of a highly modified region responded to a 13-year drought (the 'Big Dry'), followed by a two-year period of substantially higher than average rainfall (the 'Big Wet'). Location: Temperate woodlands in north central Victoria, Australia. Methods: We used two spatially extensive, long-term survey programmes, each of which was repeated three times: early and late in the Big Dry, and in the Big Wet. We compared species-specific changes in reporting rates between periods in both programmes to explore the resistance (the ability to persist during drought) and resilience (extent of recovery post-drought) of species to climate extremes. Results: There was a substantial decline in the reporting rates of 42-62% (depending on programme) of species between surveys conducted early and late in the Big Dry. In the Big Wet, there was some recovery, with 21-29% of species increasing substantially. However, more than half of species did not recover and 14-27% of species continued to decline in reporting rate compared with early on in the Big Dry. Species' responses were not strongly related to ecological traits. Species resistance to the drought was inversely related to resilience in the Big Wet for 20-35% of the species, while 76-78% of species with low resistance showed an overall decline across the study period. Conclusions: As declines occurred largely irrespective of ecological traits, this suggests a widespread mechanism is responsible. Species that declined the most during the Big Dry did not necessarily show the greatest recoveries. In already much modified regions, climate extremes such as extended drought will induce on-going changes in the biota. © 2014 John Wiley & Sons Ltd.

It is commonly assumed that, in the realm of ethical decision making at the end-of-life, ‘luck’ and ‘risk’ do not intrude. Nonetheless ‘moral luck’ (where happenstance makes a moral difference) does intrude and can have an unanticipated impact on the ultimate moral outcomes of end-of-life care. In the interests of upholding the ethical standards of end-of-life care, healthcare providers have increasingly relied on ethical principlism as a rational decision-guiding frame in the sincere belief that such an approach will enable patient selfdetermination and control over treatment decisions when needing end-of-life care. Due to contextual variables and associated uncertainties in end-of-life care, however, the intended moral outcomes of appeals to commonly accepted ethical principles (in particular the principle of autonomy) are not always realized. What is not always appreciated is that whether ‘good’ or ‘bad’ moral outcomes are achieved can be as much a matter of chance as of choice. This essay explores the relevance and possible implications of moral luck in end-of-life decision making and care. A key conclusion of the paper is that the notion of moral luck needs to be taken seriously in end-of-life care contexts since it can have an unanticipated impact on the outcomes of the decisions that are made and thereby on the moral interests of patients facing the end of their lives.

US censorship of public discussion of the bombings during the Allied Occupation of Japan ensured that the Japanese public knew little about the human consequences of the atomic bombing of Hiroshima and Nagasaki. When hibakusha poets seek a public audience for their poetry, their experiences make them potentially powerful public intellectuals. As Noam Chomsky has observed, the most effective public intellectuals are dissidents who act from the margins. Tōge Sankichi and Kurihara Sadako became activists and their poetry offers a powerful and rousing response to the atomic bombing and lobbies for nuclear disarmament. The simplicity and accessibility of these poems is essential to the public dissemination of their message and Kurihara’s and Tōge’s identification as public intellectuals. This article examines the ways in which hibakusha poets can be recognised as public intellectuals when they seek public audiences for their work. Discussion hinges on a number of considerations centred on public intellectualism, trauma and the uses of language.

Decisions to withdraw or withhold life-sustaining treatment are contentious, and offer difficult moral dilemmas to both medical practitioners and the judiciary. This issue is exacerbated when the patient is unable to exercise autonomy and is entirely dependent on the will of others.This book focuses on the legal and ethical complexities surrounding end of life decisions for critically impaired and extremely premature infants. Neera Bhatia explores decisions to withdraw or withhold life-sustaining treatment from critically impaired infants and addresses the controversial question, which lives are too expensive to treat? Bringing to bear such key issues as clinical guidance, public awareness, and resource allocation, the book provides a rational approach to end of life decision making, where decisions to withdraw or withhold treatment may trump other competing interests.The book will be of great interest and use to scholars and students of bioethics, medical law, and medical practitioners.

The quality of life of people with end stage kidney disease (ESKD) has traditionally been measured using instruments that emphasise objective health status. The present study validates an alternative measure, the Personal Wellbeing Index (PWI), which measures subjective wellbeing. An Australian ESKD sample (N = 172, Mean age = 64.04, SD = 14.82) completed the PWI as well as health-specific quality of life measures. The PWI was subject to confirmatory factor analysis, and a series of regressions and between-group comparisons were performed to reveal that it is a psychometrically appropriate measure for this sample. The PWI and health-specific measures each yield different and complementary results. Thus, the PWI is proposed as a complement to existing health-related quality of life tools, in order to broaden understanding of the patient’s subjective experience. The resulting profile is argued to better inform targeted interventions to improve the quality of life of people with ESKD.

ABSTRACT
Diabetes is a common, increasingly prevalent chronic disease. Many people requiring palliative care have diabetes. Diabetes requires lifelong self-care tasks. Family carers frequently perform these tasks when the person with diabetes is no longer able to perform them, but there is a lack of information about carers’ needs to enable them to undertake their new care tasks. The study aimed to collect information from family carers of people with diabetes requiring palliative care about their views and experiences of managing a family member’s diabetes at the end of life and identify their needs to enable them to undertake diabetes care tasks. Data were collected during individual, semistructured interviews with 10 family members caring for a person with diabetes receiving palliative care. The 4 key themes identified were as follows: I didn’t know what to do: it’s a big responsibility; I need education; and it’s important to manage diabetes. Family members/carers feel anxious about their increasing responsibility when caring for their family member’s diabetes and need information and education to help them monitor and interpret blood glucose levels, mange high or low blood glucose levels, and administer glucose-lowering medicines safely and confidently.

In this article I will present two arguments. First, the argument that the time travel television series historically provided viewers with a spectacular temporal and spatial alternative to the routine of everyday life, the regulation of television scheduling, and the small-world confines of domestic subjectivity. Taking the decades of the 1970s and 1980s, predominantly in a UK viewing environment, I will suggest that the special effect rendering of the time travel sequence expanded the viewer’s material universe, and affectively wrenched the television set free from the strictures of scheduling and realist programming. Further, the time travel series readily and regularly took the domestic space, the ordinary day and the everyman/ person into awesome environments and situations that suggested alternative lifestyles and behaviours, with a different existential tempo and rhythm. At a narrative, thematic, meta- textual, and aesthetically spectacular level, television time travel saw to the wonderful end of the working day. Case studies include Sapphire and Steal, Dr Who, and Quantum Leap. Second, the article will argue that rather than the contemporary time travel television series being an extraordinary alternative to ordinary life, they instead articulate convergence culture, deregulation, multiple channel viewing, and time-shift culture where there is no such thing as an ordinary working day or domestic viewing context.

Diabetes complications are common and can contribute to unpleasant symptoms, depression and reduced quality of life. A palliative approach to diabetes care in patients with complications, including modified metabolic targets, can reduce symptoms and hospital admissions and improve quality of life and care transitions. GPs have a key role in co-ordinating palliative and end-of-life care in these patients.

BACKGROUND: Total costs associated with care for older people nearing the end of life and the cost variations related with end of life care decisions are not well documented in the literature. Healthcare utilisation and associated health care costs for a group of older Australians who entered Transition Care following an acute hospital admission were calculated. Costs were differentiated according to a number of health care decisions and outcomes including advance directives (ADs).

METHODS: Study participants were drawn from the Coaching Older Adults and Carers to have their preferences Heard (COACH) trial funded by the Australian National Health and Medical Research Council. Data collected included total health care costs, the type of (and when) ADs were completed and the place of death. Two-step endogenous treatment-regression models were employed to test the relationship between costs and a number of variables including completion of ADs.

RESULTS: The trial recruited 230 older adults with mean age 84 years. At the end of the trial, 53 had died and 80 had completed ADs. Total healthcare costs were higher for younger participants and those who had died. No statistically significant association was found between costs and completion of ADs.

CONCLUSION: For our frail study population, the completion of ADs did not have an effect on health care utilisation and costs. Further research is needed to substantiate these findings in larger and more diverse clinical cohorts of older people.
