The South West Trawl Fishery draft management plan.

This paper outlines a proposal for management of trawl fisheries operating in waters less than 200m deep between the Moore River north of Perth and Cape Leeuwin. Off Fremantle, potential and actual user conflicts between trawling and the requirements of recreational fishing and other forms of commercial fishing point to the need to gradually phase out trawling in this area. A limited entry fishery, with no licence transferability, is therefore proposed

Axion-Photon Conversion in 3D Media and Astrophysical Plasmas

With axions now a primary candidate for dark matter, understanding their indirect astrophysical signatures is of paramount importance. Key to this is the production of photons from axions in magnetised astrophysical plasmas. While simple formulae for axion-photon mixing in 1D have been sketched several decades ago, there has recently been renewed interest in robust calculations for this process in arbitrary 3D plasmas. These calculations are vital for understanding, amongst other things, the radio production from axion dark matter conversion in neutron stars, which may lead to indirect axion dark matter detection with current telescopes or future searches, e.g., by the SKA. In this paper, we derive the relevant transport equations in magnetised plasmas. These equations describe both the production and propagation of photons in an arbitrary 3D medium due to the resonant conversion of axions into photons. They also fully incorporate the refraction of photons, and we find no evidence for a conjectured phenomenon of de-phasing. Our result is free of divergences which plagued previous calculations, and our kinetic theory description provides a direct link between ray tracing and the production mechanism. These results mark an important step toward solving one of the major open questions concerning indirect searches of axions in recent years, namely how to compute the photon production rate from axions in arbitrary 3D plasmas.Comment: 45 Pages, 5 figures.

The Oombulgurri Project Clancy Committee report

In early August the Oombulgurri community requested assistance in the following terms. On behalf of the Oombulgurri Community, we invite assistance in developing the grain and pasture cropping at Oombulgurri. We have experimented with peanuts, sorghum, and many varieties of vegetables. This has tested the reality of hopes to expand acreage and varieties to become self-sufficient in stock feed. The Farm and Garden Guild now needs the expertise of your services to plan a four-year programme. vie need assistance in choosing from the many options, opinions and advices available from Australia and elsewhere, for grain production, pastures, methods appropriate to our geography, and machinery, to minimise expenditure and produce food for the stock expansion necessary to be self-sufficient in locally produced food for the town. Our concerns so far have been to start poultry, pigs, goats and horses stocking to provide useful work for everyone and food „ ually increase production and decrease imports with the appropriate use of manpower, water and other resources. We believe we can produce stock feed locally and grad- We attach our initial estimates of need which includes an estimate of projected stocking and machinery needs as well as a list of what is on hand

Modelling ecosystem adaptation and dangerous rates of global warming

This is the author accepted manuscript. The final version is available from Portland Press via the DOI in this recordWe are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).University of ExeterCSSP-Brazi

A sexual murder prevented? A case study of evidence-based practice

Clinical work with offenders with histories of sexual violence is an important aspect of forensic practice. A key feature of this is the clinical interview, which allows individual and offence-related issues to be explored. Research suggests that some sexual offences contain sexual motivations and may therefore be related to deviant sexual fantasies. This case study reports on the assessment and formulation of a patient detained in a regional secure unit. Although he had no previous sexual convictions, he had a history of being sexually violent towards others. During clinical interviews the patient disclosed having deviant sexual fantasies for several years relating to the rape and strangulation of women. These fantasies fuelled his daily masturbatory behaviour and he reported several attempts to enact them before his detention in hospital. Once in hospital the object of his sexual desires became a female nurse, whom he wanted to rape and strangle, the idea of which again fuelled his daily masturbatory behaviour. These disclosures necessitated preventative measures being taken by his clinical team and re-enforced the importance of giving due consideration to violent sexual fantasies and the importance of evidence-based risk formulations that inform the care and management of forensic patients
