Stuck inside a mobile

A diverse, hybrid text which interweaves poetry and prose to form a series of meditations on the theme of ‘art and lies’, specifically lies of connection and the pervasiveness of mobile phone use and the way that phone conversations act as temporary rooms for voices which are lifted out of bodies (and out of countries). In the disembodiment of the voice our unconscious fictions are revealed.

Michael Polanyi and Karl Popper : the fraying of a long-standing acquaintance

Based upon archival correspondence and their publications, this essay analyzes the interaction of Karl Popper and Michael Polanyi. Popper sent Polanyi for review in 1932 an early draft of The Logic of Discovery. Friedrich Hayek helped both Polanyi and Popper publish some of their writings in the forties. Polanyi renewed his acquaintance with Popper in the late forties when Popper took a position at the London School of Economics and they met to discuss common interests. In the early fifties, as Polanyi prepared and presented his Gifford Lectures and published The Logic of Liberty, Polanyi became increasingly clear and articulate in distinguishing his social philosophy and philosophy of science from Popper’s ideas. Polanyi’s 1952 paper “The Stability of Belief” forthrightly presented Polanyi’s post-critical ideas that Popper overtly rejected in an important letter. After this, they had little to do with each other.

Transitioning communities : community, participation and the transition town movement

The Transition Town (TT) movement has grown to become a global phenomenon aimed at assisting towns and communities to envision sustainable and self-reliant futures post peak oil. Arguably, this movement offers an exciting alternative to traditional notions of growth and development. This paper explores the rise of the TT movement focusing particularly on the processes involved in establishing a ‘TT’ raising questions pertaining to governance and to notions of participatory democracy within the movement.

Interspecific variations in the gastrointestinal microbiota in penguins

Despite the enormous amount of data available on the importance of the gastrointestinal (GI) microbiota in vertebrate (especially mammals), information on the GI microbiota of seabirds remains incomplete. As with many seabirds, penguins have a unique digestive physiology that enables them to store large reserves of adipose tissue, protein, and lipids. This study used quantitative real-time polymerase chain reaction (qPCR) and 16S rRNA gene pyrosequencing to characterize the interspecific variations of the GI microbiota of four penguin species: the king, gentoo, macaroni, and little penguin. The qPCR results indicated that there were significant differences in the abundance of the major phyla Firmicutes, Bacteroides, Actinobacteria, and Proteobacteria. A total of 132,340, 18,336, 6324, and 4826 near full-length 16S rRNA gene sequences were amplified from fecal samples collected from king, gentoo, macaroni, and little penguins, respectively. A total of 13 phyla were identified with Firmicutes, Bacteroidetes, Proteobacteria, and Fusobacteria dominating the composition; however, there were major differences in the relative abundance of the phyla. In addition, this study documented the presence of known human pathogens, such as Campylobacter, Helicobacter, Prevotella, Veillonella, Erysipelotrichaceae, Neisseria, and Mycoplasma. However, their role in disease in penguins remains unknown. To our knowledge, this is the first study to provide an in-depth investigation of the GI microbiota of penguins.

Community based rehabilitation for people with disability in Iraq

This thesis explores the role of government and non-government organisations and international agencies in community based rehabilitation in Iraq. It examines the possibility of initiating and running community-based rehabilitation programmes for people with disability by NGOs regardless of Iraqi government commitment or participation. The research results show that implementation of CBR in Iraq is vital but not widely- spread. Non-government organisations seem more active, committed and capable in the time being to initiate, run and manage CBR programmes compared to the government of Iraq. Despite the high numbers of people with disabilities and lack of capacity to respond to their needs, there is little evidence that the Iraqi government has made efforts in adopting CBR as a cost-effective response.

Rural and regional Australian public accounting firm services : service provision, concerns and tensions

Public accounting firms provide a necessary and important service for rural and regional areas. However, the provision of high-quality services is hindered by a number of factors. This paper reports the findings from a large-scale survey of professional accounting firm practitioners located in rural and regional Australia, identifying factors causing concerns and tensions and quantifying their scope and importance. Prominent concerns and tensions identified include adverse effects arising from the employment market, communications technology developments and legislation such as the Corporate Law Economic Reform Program (Audit Reform and Corporate Disclosure) Act 2004 and the Financial Services Reform Act 2001.

Scientific foundations for an IUCN red list of ecosystems

 An understanding of risks to biodiversity is needed for planning action to slow current rates of decline and secure ecosystem services for future human use. Although the IUCN Red List criteria provide an effective assessment protocol for species, a standard global assessment of risks to higher levels of biodiversity is currently limited. In 2008, IUCN initiated development of risk assessment criteria to support a global Red List of ecosystems. We present a new conceptual model for ecosystem risk assessment founded on a synthesis of relevant ecological theories. To support the model, we review key elements of ecosystem definition and introduce the concept of ecosystem collapse, an analogue of species extinction. The model identifies four distributional and functional symptoms of ecosystem risk as a basis for assessment criteria: a) rates of decline in ecosystem distribution; b) restricted distributions with continuing declines or threats; c) rates of environmental (abiotic) degradation; and d) rates of disruption to biotic processes. A fifth criterion, e) quantitative estimates of the risk of ecosystem collapse, enables integrated assessment of multiple processes and provides a conceptual anchor for the other criteria. We present the theoretical rationale for the construction and interpretation of each criterion. The assessment protocol and threat categories mirror those of the IUCN Red List of species. A trial of the protocol on terrestrial, subterranean, freshwater and marine ecosystems from around the world shows that its concepts are workable and its outcomes are robust, that required data are available, and that results are consistent with assessments carried out by local experts and authorities. The new protocol provides a consistent, practical and theoretically grounded framework for establishing a systematic Red List of the world’s ecosystems. This will complement the Red List of species and strengthen global capacity to report on and monitor the status of biodiversity.

Grain refinement of an extruded Mg alloy via na microalloying

The effect of 0.3 wt pct Na on the microstructure of extruded alloy Mg-2Sn-1Zn is examined. We report that Na stabilizes the Mg2Sn phase, resulting in its precipitation during extrusion under conditions where a solid solution is otherwise expected. This effect appears to be thermodynamic in nature and is different from the kinetic enhancement of low- temperature aging reported by Mendis et al. [Phil. Mag. Letters, 86 (2006), 443]. The precipitates of the current study enable useful refinement of the grain size.

Animal-borne sensors successfully capture the real-time thermal properties of ocean basins

Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to predict and quantify the consequences of this change is severely limited by the paucity of in situ oceanographic measurements. Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem because marine animals range widely across the world’s ocean basins and visit remote and often inaccessible locations. However, unlike the information being collected from conventional oceanographic sensing equipment, which has been validated, the data collected from instruments deployed on marine animals over long periods has not. This is the first long-term study to validate in situ oceanographic data collected by animal oceanographers. We compared the ocean temperatures collected by leatherback turtles (Dermochelys coriacea) in the Atlantic Ocean with the ARGO network of ocean floats and could find no systematic errors that could be ascribed to sensor instability. Animal-borne sensors allowed water temperature to be monitored across a range of depths, over entire ocean basins, and, importantly, over long periods and so will play a key role in assessing global climate change through improved monitoring of global temperatures. This finding is especially pertinent given recent international calls for the development and implementation of a comprehensive Earth observation system (see http://iwgeo.ssc.nasa.gov/documents.asp?s=review) that includes the use of novel techniques for monitoring and understanding ocean and climate interactions to address strategic environmental and societal needs.
