Left-wing melancholies

With the recent passing of the world's "best-known unknown filmmaker," Chris Marker, it is axiomatic that left-wing melancholy now includes the ongoing loss of previously lost causes – a paradox that suggests the true address of all lost causes worth defending is a strange confluence of past and futural states, as one state. This double loss as gain is also the primary mark of the "landscape" of pessimistic optimism that also denotes the foremost position to occupy today in the battles associated with capitalist End Times (Slavoj Žižek's term). Cultural ecology is no longer what it once was – that is to say, a strange amalgam of vernacular essences perpetrated in the rather forlorn 1970s and/or the insistent and incessant production of difference. Instead, cultural ecology invokes spectral civil war – arguably the very state of things today – and the return of "the dead" in the persistence of forms of high-formalist and high-conceptualist works of art and architecture. This paper examines the late works of the late Chris Marker, including the very short videos he uploaded to You Tube under the pseudonym "Kosinki" from 2007 to 2011, an event contiguous with his return to exhibiting very-still photography from 2006 to 2011. Marker's simultaneous returns to still photography and the short film-essay are both magnificent gestures toward the austerities required of present-day media to effect the necessary "return" to what is always present in one form or another anyway – the non-place between world and world-to-come.

Raining blood and money

A fictocritical piece based on a fire in New York.
A girl jumps from the ninth floor of the Asch Building. People on the sidewalk are screaming for her not to jump. But she has to jump. As she stands on the ledge, her back against the open window, the fire is burning the clothes off her back. She has her head bent forward so her hair doesn't catch alight as she waves a handkerchief at the crowd. The windows on the floor beneath her start to explode. Tongues of flame lick at her feet. So she jumps. It's a definite jump, as she bends her knees before she leaps over the edge. It's not a graceful jump. Her arms begin to flail as she struggles to stay upright. There are gasps from the crowd, a few screams. Some people turn away. Others are transfixed, watching her as she falls. Suddenly, her dress catches on a hook jutting out of wall below and she is suspended in the air, mid-fall. But the ladders still can't reach her and so it is just a cruel pause in her inevitable death. She hangs there like a ragdoll until her dress burns itself free from her body and she resumes her fall. She lands on the pavement on the west - ward side of New York University building. Thud-dead...

Increased mortality of naive varanid lizards after the invasion of non-native can toads (bufo marinus)

Exotic animal and plant species introduced into the Australian continent often imparted catastrophic effects on the indigenous fauna and flora. Proponents of biological control introduced the South American Cane Toad (Bufo marinus) into the sugar cane fields of Queensland in 1935. The Cane Toad is one of the most toxic bufonids and when seized by naive Australian predators, the toxin usually kills the attacker. One group of Australian squamate reptiles that are very susceptible to Cane Toad toxins is varanid lizards. Prior to Cane Toad invasion of our study area, the Adelaide River floodplain of the Northern Territory of Australia, annual mortality of adult male radio-tagged yellow-spotted Goannas (Varanus panoptes) was very low. After the arrival of toads in October 2005, all radio-tracked goannas were found dead in August 2006, most likely attempting to feed on the toads. Our results suggest that invasive Cane Toads place naive adult male Yellow-spotted Goannas at risk of possibly >90% mortality. This increase in mortality could reduce the genetic diversity and hamper long-term survival of these large carnivorous lizards.

Something like an emergency

‘Something like an emergency’, a sonic poem recorded on CD, investigates the hunger of writing as a desire, not for a return of the dead, but for a breakthrough of impasses in language, both in love and in the writer’s (frustrated) translation of vision. Proceeding from Bachelard’s phenomenological observation that the poetic image puts language in a state of emergence, this work argues, instead, that poetry puts language in a state of emergency. Deleuze and Guattari’s idea of music as a deterriorialization of the refrain; a rhythmic pattern which marks out a territory, is invoked in both the music performance and in the words. The writing uses a ‘matting’ (rhizomatic) effect in its verse fragments which echo and refract others. Reverberation is also explored in the piano and its sonic processing which provides elements of dissonance and consonance, refracting dialogues in the text. Voice and music sometimes argue, sometimes agree, and sometimes are indistinguishable. However, this dialectic is further disturbed: at times the piano and voice seem to pay no attention to each other, taking off on their own ‘lines of flight’, in subversion of ‘collaboration’. In its use of recorded improvisational techniques this work also challenges the ‘superiority’ of live improvisation.
It was first performed at Double Dialogues conference, ‘The Hunger Artist: Food and the Arts’, Toronto, 2010. The text and accompanying discursive article form a book chapter in 2012 Food and Appetites: The Hunger Artist and the Arts, Ann McCulloch and Pavlina Radia(eds). It has been broadcast on RRR, 3CR radios and is released on CD and Youtube. By invitation it was performed at the Midsumma Festival, 2014.

Requiem for Empire : Fabian Ware and the Imperial War Graves Commission

More than one million soldiers of the British Empire died in the First World War. The Imperial War Graves Commission, created in 1917, had as its mandate the obligation to care for their graves and memorials, in 1850 cemeteries in more than 100 countries around the globe. Its founder, Fabian Ware, hoped and expected this Commission to have even more enduring effects, yet the political origins of the organisation remain little understood. This chapter looks beyond the monuments erected by the Imperial War Graves Commission to the ideals and intent of its creators. It argues that the driving force behind this major commemorative work was not a desire to represent any fundamental break with the past, but an attempt to produce an institution that symbolised imperial cooperation and memorialised the war and its dead in a way that would continue to place the British Empire at the centre of world affairs.

Prevalence of beak and feather disease virus in wild Platycercus elegans: comparison of three tissue types using a probe-based real-time qPCR test

The detection of avian viruses in wild populations has considerable conservation implications. For DNA-based studies, feathers may be a convenient sample type for virus screening and are, therefore, an increasingly common technique. This is despite recent concerns about DNA quality, ethics, and a paucity of data comparing the reliability and sensitivity of feather sampling to other common sample types such as blood. Alternatively, skeletal muscle tissue may offer a convenient sample to collect from dead birds, which may reveal viraemia. Here, we describe a probe-based quantitative real-time PCR for the relative quantification of beak and feather disease virus (BFDV), a pathogen of serious conservation concern for parrots globally. We used this method to test for BFDV in wild crimson rosellas (Platycercus elegans), and compared three different sample types. We detected BFDV in samples from 29 out of 84 individuals (34.5%). However, feather samples provided discordant results concerning virus presence when compared with muscle tissue and blood, and estimates of viral load varied somewhat between different sample types. This study provides evidence for widespread infection of BFDV in wild crimson rosellas, but highlights the importance of sample type when generating and interpreting qualitative and quantitative avian virus data.

Placing sensors for area coverage in a complex environment by a team of robots

Existing solutions to carrier-based sensor placement by a single robot in a bounded unknown Region of Interest (ROI) do not guarantee full area coverage or termination. We propose a novel localized algorithm, named Back-Tracking Deployment (BTD). To construct a full coverage solution over the ROI, mobile robots (carriers) carry static sensors as payloads and drop them at the visited empty vertices of a virtual square, triangular, or hexagonal grid. A single robot will move in a predefined order of directional preference until a dead end is reached. Then it back-tracks to the nearest sensor adjacent to an empty vertex (an "entrance" to an unexplored/uncovered area) and resumes regular forward movement and sensor dropping from there. To save movement steps, the back-tracking is carried out along a locally identified shortcut. We extend the algorithm to support multiple robots that move independently and asynchronously. Once a robot reaches a dead end, it will back-track, giving preference to its own path. Otherwise, it will take over the back-track path of another robot by consulting with neighboring sensors. We prove that BTD terminates within finite time and produces full coverage when no (sensor or robot) failures occur. We also describe an approach to tolerate failures and an approach to balance workload among robots. We then evaluate BTD in comparison with the only competing algorithms SLD [Chang et al. 2009a] and LRV [Batalin and Sukhatme 2004] through simulation. In a specific failure-free scenario, SLD covers only 40-50% of the ROI, whereas BTD covers it in full. BTD involves significantly (80%) less robot moves and messages than LRV.

When good dictators go bad: examining the 'transformation' of Colonel Gaddafi

On October 20, 2011, the 42 year rule of Colonel Muammar Gaddafi came to a violent end after months ofintense and brutal fighting. The violence in which Gaddafi died and the ensuing abuse of his dead body by his killers wascaptured on film and broadcast around the world. This gruesome end was the antithesis to his rise to power in 1969,where he was welcomed as a savior and a hero. Until his death, Gaddafi was the longest-serving non-monarchical Headof State and was considered by most scholars more likely to die of natural causes than be overthrown by his people. Sowhat happened in those 42 years that caused Gaddafi to go from beloved liberator to hated oppressor? And what is hislasting legacy for the country he ruled for over four decades?

Summer is a good time for informal education

Students look forward to summer because usually it means a break from formal and non-formal education. Formal education refers to education in formal educational institutions, such as pre-schools, primary, secondary and tertiary educational institutions and other registered training organisations. Non-formal education refers to organised educational activity outside the established formal system, that is intended to deliver a defined set of learning objectives to an identifiable group of learners (Chemistry in Australia, October 2014, page 33). Informal education refers to all learning outside the formal non-formal educational system; informal education is often associated with life-long learning as it can include reading non-fiction books and scholarly articles, viewing documentaries and other informal professional development. Informal education can also include travel to other countries and climates. Social constructivist theory maintains that learning occurs in social settings; conversely, most learners are limited by their cultural experiences. For example, Australian students have little first-hand experience of sublimation, but this is commonly observed in very cold climates when frost, ice or snow apparently “disappears” as it sublimes to water vapour, without passing through the liquid state. A favourite summertime activity is to go to the movies, especially in air-conditioned cinemas on a hot day or night. Watching movies are a form of virtual travel, and many educators make use of movies to illustrate chemistry concepts. Some movie producers want a sense of authenticity and work hard to get the details right, even though those details might be incidental to the main plot. For example, in Centurion, Roman soldiers fail in their rescue attempt, and are taunted by the Picts for stupidity -- they would have succeeded if they had only realised that metal become brittle in the cold. Another favourite example comes from The Lord of the Rings: The Two Towers, when Bilbo, Samwise and Gollum are crossing the Dead Marshes and see lights that appear to float over the Marshes. These wills-o-the-wisp have been known for centuries, and was the subject of a debate between George Washington and his officers. Washington and Thomas Paine, “the Father of the American Revolution”, believed that the lights were due to a flammable gas released from the marsh, while Washington’s officers believed that the lights were due to a flammable liquid on the surface of the marsh. On Guy Fawkes Night, 5 November, 1783, the Washington-Paine experiment showed that when mud at the bottom of a river was disturbed, bubbles of flammable gas rose to the surface of the water. (Unknown to Washington and Paine, Alessandro Volta had performed a similar experiment in 1776.) A problem with informal education is that it is often unguided. Students may find it difficult to discern the difference between scientific reality and an artistic distortion of reality in novels and movies. Educators have an important role here. If we only teach facts and concepts, learners will be dependent on a teacher. If however, we foster students’ curiosity and ability to exercise judgement, they will be able to learn for themselves, not just during the summer, but also in every season of every year.

Transplantation of the heart after circulatory death of the donor: time for a change in law?

Australia has a shortfall in donated hearts for transplantation.Hearts are usually procured from brain dead donors, but procurement from circulatory dead donors is a potential additional source.However, heart transplantation after circulatory death of the donor may not conform to the dead donor rule.An amendment in law is required to permit heart procurement for transplantation after circulatory death.

His daughter's father

His Daughter’s Father is an experimental multimedia-drawing about presence: of a subject that is depicted simultaneously with affect (alive/present) and stilled (dead/past), and of representation that continuously re-presents itself in real and imagined time. Imagery moves between performative drawing, the digital moving image, and the stilled representation.

Do the numbers and locations of road-killed anuran carcasses accurately reflect impacts of vehicular traffic?

Road-killed animals are easy and inexpensive to survey, and may provide information about species distributions, abundances, and mortality rates. As with any sampling method, however, we need to explore methodological biases in such data. First, how does an animal's behavior (e.g., use of the center vs. periphery of the road) influence its vulnerability to vehicular traffic? Second, how rapidly do post-mortem processes (scavenging by other animals, destruction or displacement by subsequent vehicles) change the numbers and locations of roadkills? Our surveys of anurans on a highway in tropical Australia show that different anuran species are distributed in different ways across the width of the road, and that locations of live versus dead animals sometimes differ within a species. Experimental trials show that location on the road affects the probability of being hit by a vehicle, with anurans in the middle of the road begin hit 35% more often than anurans on the edges; thus, center-using species are more likely to be hit than edge-using taxa. The magnitude of post-mortem displacement and destruction by subsequent vehicles depended on anuran species and body size. The mean parallel displacement distance was 122.7 cm, and carcasses of thin-skinned species exhibited greater post-mortem destruction. Scavenging raptors removed 73% of carcasses, most within a few hours of sunrise. Removal rates were biased with respect to size and species. Overall, our studies suggest that investigators should carefully evaluate potential biases before using roadkill counts to estimate underlying animal abundances or mortality rates.

The effects of topographic variation and the fire regime on coarse woody debris: insights from a large wildfire

Coarse woody debris (CWD) is a common structural component of terrestrial ecosystems, and provides important habitat for biota. Fires modify the distribution of CWD, both spatially and temporally. Changes in fire regimes, such as those arising from prescribed burning and changing climatic conditions, make it critical to understand the response of this resource to fire. We created a conceptual model of the effects of fire on logs and dead trees in topographically diverse forests in which trees often survive severe fire. We then surveyed paired sites, in a damp gully and adjacent drier slope, ~3.5. years after a large wildfire in south-eastern Australia. Sites were stratified by fire severity (unburnt, understorey burnt and severely burnt), and fire history (burnt ≤3. years or ≥20. years prior to the wildfire). Both components of the fire regime influenced CWD availability in gullies. Severe wildfire and fire history ≤3. years reduced the volume of small logs (10-30. cm diameter) in gullies, while severe wildfire increased the number of large dead trees in gullies. CWD on slopes was not affected by fire severity or history at ~3.5. years post-fire. Log volumes on slopes may recover more quickly after wildfire through rapid collapse of branches and trees. Gullies generally supported more logs than slopes, but longer inter-fire intervals in gullies may allow fuel loads to accumulate and lead to comparatively larger fire impacts. Given that fire severity and fire interval are predicted to change in many fire-prone ecosystems in coming decades, this study highlights the importance of understanding the interacting effects of multiple components of the fire regime with landscape structure. In particular, variation in fire interval and fire severity in relation to topographic position will influence the pattern of accumulation of coarse woody debris across the landscape, and therefore the structure and quality of habitats for biota.

Enhancement of the antifouling properties and filtration performance of poly(ethersulfone) ultrafiltration membranes by incorporation of nanoporous titania nanoparticles

Nanoporous titania nanoparticles (NTNs) were synthesized and used as an additive at a low concentration of 0.1-1 wt % in the fabrication of poly(ethersulfone) (PES) ultrafiltration membranes via non-solvent-induced phase separation. The structure and properties of nanoparticles were characterized using nitrogen sorption, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The NTNs have a size distribution with a particle size of mainly <100 nm and have a Brunauer, Emmett, and Teller surface area of ∼100 m2 g-1. The modified membranes were fabricated and investigated in terms of their pure water flux, solute rejection, and fouling resistance. The water permeability and molecular weight cutoffs (MWCOs) of membranes were determined under constant-pressure filtration in dead-end mode at 100 kPa. The membrane fouling resistance was characterized under constant flux operation using bovine serum albumin as a model foulant. The membranes were characterized in terms of morphology, porosity, pore size distribution, energy-dispersive X-ray spectroscopy, contact angle goniometry, surface free energy, and viscosity of the dope solution. Overall, the modified membrane showed increased wettability and reduced surface free energy and pore size. The modified UF membrane with 0.5 wt % NTN loading exhibited improved fouling resistance (fouling rate of 0.58 kPa/min compared to a rate of 0.70 kPa/min for the control membrane) with ∼80% water flux recovery. The same membrane showed an ∼20% increase in water flux, an improvement in MWCO, and a narrower pore size distribution.
