The borderscape of detention: media depictions of the denizens of Woomera

Abstract: Border anxieties pervade discussions of refugees, asylum seekers and the defence of white privilege. Many scholars have explored the significance of borderlands/borderscapes in shaping and defending the white western self. The defence of a ‘vulnerable’ white subject includes the demonisation of the asylum seeker other and a deep fear of the erosion of ‘patriarchal white sovereignty’. In print news texts about lip sewing by asylum seekers, a common theme is the location of Woomera and other detention centres as ‘states of exception’ or part of ‘not-Australia’. Using Kristeva’s notion of the ‘abject’ I explore the ‘dark’ place of Woomera and its (voluntary and involuntary) residents in news texts and the role such texts play in constituting what Rutherford (2000) called the ‘good’ white Australian subject. I explore how news texts depict ‘Woomera’ to marginalise both external and internal Others – asylum seekers and white residents – and find that such symbols of abjection reveal the extent to which news representations continue to involve white projections, desires and imaginings of the cultural and class Other.   Ron Hoenig is a PhD student in journalism and cultural studies. His thesis focuses on the Australian media‟s depiction of lip sewing by asylum seekers.

Corresponding morphological and molecular indicators of crude oil toxicity to the developing hearts of mahi mahi

Crude oils from distinct geological sources worldwide are toxic to developing fish hearts. When oil spills occur in fish spawning habitats, natural resource injury assessments often rely on conventional morphometric analyses of heart form and function. The extent to which visible indicators correspond to molecular markers for cardiovascular stress is unknown for pelagic predators from the Gulf of Mexico. Here we exposed mahi (Coryphaena hippurus) embryos to field-collected crude oil samples from the 2010 Deepwater Horizon disaster. We compared visible heart defects (edema, abnormal looping, reduced contractility) to changes in expression of cardiac-specific genes that are diagnostic of heart failure in humans or associated with loss-of-function zebrafish cardiac mutants. Mahi exposed to crude oil during embryogenesis displayed typical symptoms of cardiogenic syndrome as larvae. Contractility, looping, and circulatory defects were evident, but larval mahi did not exhibit downstream craniofacial and body axis abnormalities. A gradation of oil exposures yielded concentration-responsive changes in morphometric and molecular responses, with relative sensitivity being influenced by age. Our findings suggest that 1) morphometric analyses of cardiac function are more sensitive to proximal effects of crude oil-derived chemicals on the developing heart, and 2) molecular indicators reveal a longer-term adverse shift in cardiogenesis trajectory

Using catch rate data for simple cost-effective quota setting in the Australian spanner crab (Ranina ranina) fishery

For many fisheries, there is a need to develop appropriate indicators, methodologies, and rules for sustainably harvesting marine resources. Complexities of scientific and financial factors often prevent addressing these, but new methodologies offer significant improvements on current and historical approaches. The Australian spanner crab fishery is used to demonstrate this. Between 1999 and 2006, an empirical management procedure using linear regression of fishery catch rates was used to set the annual total allowable catch (quota). A 6-year increasing trend in catch rates revealed shortcomings in the methodology, with a 68 increase in quota calculated for the 2007 fishing year. This large quota increase was prevented by management decision rules. A revised empirical management procedure was developed subsequently, and it achieved a better balance between responsiveness and stability. Simulations identified precautionary harvest and catch rate baselines to set quotas that ensured sustainable crab biomass and favourable performance for management and industry. The management procedure was simple to follow, cost-effective, robust to strong trends and changes in catch rates, and adaptable for use in many fisheries. Application of such "tried-and-tested" empirical systems will allow improved management of both data-limited and data-rich fisheries. © 2010 International Council for the Exploration of the Sea

Cobia (Rachycentron canadum) hatchery-to-market aquaculture technology: recent advances at the University of Miami Experimental Hatchery (UMEH) Tecnologia da criação de beijupirá (Rachycentron canadum): recentes avanços do Laboratório de Larvicultura Experimental da Universidade de MIAMI (UMEH)

Among warm-water marine fishes, cobia is one of the best aquaculture candidate species in the world. Currently there are commercial culture operations in several Asian countries and the industry has started developing elsewhere, including the Western Central Atlantic region. Significant research has been conducted at the University of Miami's Aquaculture Program / University of Miami Experimental Hatchery (UMEH) during the last eight years, involving research to develop and optimize advanced technology to demonstrate the viability of raising hatchery-reared cobia in collaboration with the private sector. This paper reviews some of this recent advances for the development of Hatchery-to-Market Aquaculture Technology for commercial production of cobia.<br>Dentre os peixes marinhos de águas quentes, o bijupirá é um dos grandes candidatos para a aquacultura no mundo. Atualmente, existem operações comerciais em vários países Asiáticos e a indústria iniciou suas operações em outros locais, incluindo a região do Atlântico Central. Pesquisas têm sido realizadas no "University of Miami's Aquaculture Program / University of Miami Experimental Hatchery (UMEH)" durante os últimos oito anos envolvendo o desenvolvimento e otimização de tecnologia avançada para demonstrar a viabilidade da criação de bijupirá com colaboração com o setor privado. Este artigo revisa alguns destes avanços recentes para o desenvolvimento da tecnologia da larvicultura para o mercado para a produção comercial de bijupirá
