Graphic satire and public life in the age of terror

This paper investigates media representations of international insecurity through a selection of newspaper cartoons from some of the major daily Australian broadsheets. Since 2001, cartoonists such as Bruce Petty, John Spooner and Bill Leak (in The Age and The Australian) have provided an ongoing and vehement critique of the Australian government’s policies of ‘border protection’, the ‘war on terror’ and the words of mass distraction associated with Australia joining the war in Iraq. Cartoonists are often said to represent the ‘citizen’s perspective’ of public life through their graphic satire on the editorial pages of our daily newspapers. Increasingly, they can also be seen to be fulfilling the role of public intellectuals, defined by Richard A. Posner as ‘someone whose place it is publicly to raise embarrassing questions, to confront orthodoxy and dogma, to be someone who cannot easily be co-opted by governments and corporations’. Cartoonists enjoy an independence and freedom from censorship that is rarely extended to their journalistic colleagues in the print media and it is this independence that is the vital component in their being categorised as public intellectuals. Their role is to ‘question over and over again what is postulated as self-evident, to disturb people’s mental habits, to dissipate what is familiar and accepted, to re-examine rules and institutions’ (Posner, 2003: 31). With this useful — if generalised — definition in mind, the paper considers how cartoonists have contributed to debates concerning international insecurity in public life since 2001.

Adaptations of strangler figs to life in the rainforest canopy

Figs are rainforest keystone species. Non-strangler figs establish on the forest floor; strangler figs establish epiphytically, followed by a dramatic transition from epiphyte to free-standing tree that kills its hosts. Free-standing figs display vigorous growth and resource demand suggesting that epiphytic strangler figs require special adaptations to deal with resource limitations imposed by the epiphytic environment. We studied epiphytic and free-standing strangler figs, and non-strangler figs in tropical rainforest and in cultivation, as well as strangler figs in controlled conditions. We investigated whether the transition from epiphyte to free-standing tree is characterised by morphological and physiological plasticity. Epiphyte substrate had higher levels of plant-available ammonium and phosphate, and similar levels of nitrate compared with rainforest soil, suggesting that N and P are initially not limiting resources. A relationship was found between taxonomic groups and plant N physiology; strangler figs, all members of subgenus Urostigma, had mostly low foliar nitrate assimilation rates whereas non-strangler figs, in subgenera Pharmacocycea, Sycidium, Sycomorus or Synoecia, had moderate to high rates. Nitrate is an energetically expensive N source, and low nitrate use may be an adaptation of strangler figs for conserving energy during epiphytic growth. Interestingly, significant amounts of nitrate were stored in fleshy taproot tubers of epiphytic stranglers. Supporting the concept of plasticity, leaves of epiphytic Ficus benjamina L. had lower N and C content per unit leaf area, lower stomatal density and 80% greater specific leaf area than leaves of conspecific free-standing trees. Similarly, glasshouse-grown stranglers strongly increased biomass allocation to roots under water limitation. Epiphytic and free-standing F. benjamina had similar average foliar delta C-13, but epiphytes had more extreme values; this indicates that both groups of plants use the C-3 pathway of CO2 fixation but that water availability is highly variable for epiphytes. We hypothesise that epiphytic figs use fleshy stem tubers to avoid water stress, and that nitrate acts as an osmotic compound in tubers. We conclude that strangler figs are a unique experimental system for studying the transition from rainforest epiphyte to tree, and the genetic and environmental triggers involved.

Quality-of-life in children and adolescents with cystic fibrosis managed in both regional outreach and cystic fibrosis center settings in Queensland

To assess the health-related quality-of-life (HRQOL) of children/adolescents with cystic fibrosis (CF) and compare HRQOL in children managed by cystic fibrosis outreach service (CFOS) with those treated in a cystic fibrosis center (CFC). To compare HRQOL of children with CF in Queensland with previously published HRQOL data from the United States and examine the relationship between HRQOL scores and pulmonary function. Study design: Participants were children/adolescents with CF and their parents managed by the Royal Children’s Hospital Queensland at a CFC or CFOS. Two HRQOL surveys were used: PedsQL™ and Cystic Fibrosis Questionnaire (CFQ). Results: There were 91 CFC and 71 CFOS participants with similar demographics. PedsQL™ total summary score was statistically higher in CFOS, P = .05. There was no significant difference in CFQ scores between groups. Queensland parents reported lower HRQOL for their children compared with US parents (P

Quality of Life in Chinese elderly people with depression

Background Depression is the most prevalent functional mental disorder of later life. It is estimated that about 5% of the elderly population of Hong Kong are suffering from depression. Aim To investigate the self-rated quality of life of community-dwelling elderly people diagnosed with depression, and to examine the relationships between quality of life and mental, physical health, functional status and social support. Methods and results A cross-sectional descriptive survey was conducted in psychiatric outpatient clinics. A convenience sample of 80 Chinese elderly people with a diagnosis of depressive disorder was recruited. Perception of quality of life was measured by the Hong Kong Chinese World Health Organization Quality of Life Scale-Brief Version. Participants' mental status, functional abilities, physical health condition, and social support status were assessed. Sixty-one (76.3%) participants were female. They were least satisfied with meaningfulness of life, life enjoyment, concentration and thinking, energy and work capacity. Functional abilities had a positive association with participants' perceived quality of life, level of depression and number of physical health conditions had a negative association. Participants had low ratings of quality of life when compared with healthy persons and persons with chronic physical problems. Findings are discussed in light of the socio-cultural environment in Hong Kong. Conclusion Comprehensive treatment and better control of depression, including different modes of medical and psychosocial intervention, could help to improve participants' perception of quality of life. A longitudinal study with a larger sample with various levels of depression and socio-demographic characteristics is recommended. Copyright © 2006 John Wiley & Sons, Ltd.

Enhancing Life in the Hyper-surveillance Mini-world of a Space Station: The Role of Situation Awareness, Communication, and Reality TV in the Life of Astronauts

This is the third article of a series entitled Astronauts as Audiences. In this article, we investigate the roles that situation awareness (SA), communications, and reality TV (including media communications) might have on the lives of astronauts in remote space communities. We examined primary data about astronauts’ living and working environments, applicable theories of SA, communications, and reality TV (including media communications). We then surmised that the collective application of these roles might be a means of enhancing the lives of astronauts in remote space communities.
