Making meat collectivities : entanglements of geneticisation, integration and contestation in livestock breeding

To explore some of the contours of this meat ‘supply chain integration’ - ‘the phrase of the moment’ according to Farmers Weekly - this chapter draws on research conducted as part of a project exploring the effects of the emergence of particular types of genetic knowledge-practice in beef cattle and sheep breeding in the UK and their entanglement with ‘traditional’ ways of knowing and valuing livestock. The research is interested in the production and circulation of genetic knowledge-practices in agriculture, in examining how such knowledge-practices become established and gain legitimacy, how they become tangled up with visual and other traditional knowledge-practices, and in the effects of genetic knowledge-practices on how cattle and sheep are bred and managed and on human-nonhuman animal relationships in livestock farming. The research has increasingly led us to explore the process of ‘geneticisation’ beyond the farm gate, to look at how the establishment of particular genetic truths or ways of rendering ‘life itself’ (Franklin, 2000) are entangled with processes of restructuring and differentiation within UK food systems

Advanced Nursing Neurological Assessment: The Post-Operative ICU Patient

This project is a useful three-fold brochure which is to be available for nurses within the Intensive Care Unit at St. Vincent\u27s Medical Center. It provides a basic step-by-step guide as to how to deliver an advanced neurological assessment on the post-operative critical patient. In a handy brochure, the nurse may quickly look up how to perform this essential, yet in-depth task in order to monitor their patient\u27s status during this critical time after surgery. It is the hope that this easy to follow brochure will assist the nurse through this advanced nursing assessment, making them feel more confident with their skills and ability to perform this independently. It also includes signs to report to the healthcare provider and patient teaching information, supporting a holistic approach to health

Trauma care in the tropics: addressing gaps in treating injury in rural and remote Australia

In Australia, over half a million people are admitted to hospital every year as a result of injury, and where you live matters. Rural populations have disproportionately higher injury hospitalisation rates (1.5 to 2.5-fold), higher rates of preventable secondary complications, higher mortality rates (up to 5-fold), and higher costs (3-fold) than patients injured in major cities. These disparities scale up rapidly with increased remoteness, and shift the service needle from ‘scoop and run’ to ‘continuum-of-care’ . Poorer outcomes, however, are not solely due to longer retrieval distances or delays; but arise from inefficiencies in one or more potentially modifiable factors in the chain-of-survival. After discussing the burden of injury in Australia, we present a brief history of retrieval services in Queensland and discuss how remoteness requires a different kind of service delivery with many moving parts from point-of-injury to definitive care. We next address the ongoing challenges for the Australian Trauma Registry, and how centralisation of data from the metropolitan cities masks the inequities in rural and remote trauma. There is an urgent need for accurate data from all service providers around Australia to inform state and federal governments, and we highlight the paucity of trauma data analysis in North Queensland. Lastly, we identify some major gaps in treating rural and remote polytrauma and en-route patient stabilisation, and discuss the relevance of combat casualty care research and practices. We conclude that a greater emphasis should be placed on collecting more robust trauma patient records, as only accurate data will drive change

Anomalous layering at the liquid Sn surface

X-ray reflectivity measurements on the free surface of liquid Sn are presented. They exhibit the high-angle peak, indicative of surface-induced layering, also found for other pure liquid metals (Hg, Ga and In). However, a low-angle peak, not hitherto observed for any pure liquid metal, is also found, indicating the presence of a high-density surface layer. Fluorescence and resonant reflectivity measurements rule out the assignment of this layer to surface-segregation of impurities. The reflectivity is modelled well by a 10% contraction of the spacing between the first and second atomic surface layers, relative to that of subsequent layers. Possible reasons for this are discussed.Comment: 8 pages, 9 figures; to be submitted to Phys. Rev. B; updated references, expanded discussio

Atomic-scale surface demixing in a eutectic liquid BiSn alloy

Resonant x-ray reflectivity of the surface of the liquid phase of the Bi$_{43}$Sn$_{57}$ eutectic alloy reveals atomic-scale demixing extending over three near-surface atomic layers. Due to the absence of underlying atomic lattice which typically defines adsorption in crystalline alloys, studies of adsorption in liquid alloys provide unique insight on interatomic interactions at the surface. The observed composition modulation could be accounted for quantitatively by the Defay-Prigogine and Strohl-King multilayer extensions of the single-layer Gibbs model, revealing a near-surface domination of the attractive Bi-Sn interaction over the entropy.Comment: 4 pages (two-column), 3 figures, 1 table; Added a figure, updated references, discussion; accepted at Phys.

Algal plankton turn to hunting to survive and recover from end-Cretaceous impact darkness

The end-Cretaceous bolide impact triggered the devastation of marine ecosystems. However, the specific kill mechanism(s) are still debated, and how primary production subsequently recovered remains elusive. We used marine plankton microfossils and eco-evolutionary modeling to determine strategies for survival and recovery, finding that widespread phagotrophy (prey ingestion) was fundamental to plankton surviving the impact and also for the subsequent reestablishment of primary production. Ecological selectivity points to extreme postimpact light inhibition as the principal kill mechanism, with the marine food chain temporarily reset to a bacteria-dominated state. Subsequently, in a sunlit ocean inhabited by only rare survivor grazers but abundant small prey, it was mixotrophic nutrition (autotrophy and heterotrophy) and increasing cell sizes that enabled the eventual reestablishment of marine food webs some 2 million years later.</p

Managing unusual sensory experiences: A feasibility trial in an At Risk Mental States for psychosis group

Objectives To conduct a feasibility study on a new, tablet-delivered treatment for unusual sensory experiences in service-users with an At Risk Mental States for psychosis. Design A mixed method design was employed, using content analysis to investigate whether service-users and therapists found the new treatment acceptable and helpful. We also collected data on the impact of treatment, but without a control group could not make any claims about effectiveness. Methods Eligible participants were contacted before starting treatment and offered the chance to participate. Assessments were conducted before and after the treatment, which typically was completed in 4–6 sessions by an accredited CBT therapist. A structured interview was used to collect qualitative feedback. Results Qualitative feedback suggested that the treatment was acceptable to service-users and therapists, and the progression criteria were met for recruitment, retention, and adherence to treatment. Conclusions The new treatment targeting subtypes of auditory and visual hallucinations was acceptable to service-users and the benefits of addressing psychological mechanisms thought to contribute to hallucinations was supported by qualitative feedback

Effects of a novel, brief psychological therapy (Managing Unusual Sensory Experiences) for hallucinations in first episode psychosis (MUSE FEP): findings from an exploratory randomised controlled trial.

Hallucinations are a common feature of psychosis, yet access to effective psychological treatment is limited. The Managing Unusual Sensory Experiences for First-Episode-Psychosis (MUSE-FEP) trial aimed to establish the feasibility and acceptability of a brief, hallucination-specific, digitally provided treatment, delivered by a non-specialist workforce for people with psychosis. MUSE uses psychoeducation about the causal mechanisms of hallucinations and tailored interventions to help a person understand and manage their experiences. We undertook a two-site, single-blind (rater) Randomised Controlled Trial and recruited 82 participants who were allocated 1:1 to MUSE and treatment as usual (TAU) (n=40) or TAU alone (n=42). Participants completed assessments before and after treatment (2 months), and at follow up (3-4 months). Information on recruitment rates, adherence, and completion of outcome assessments was collected. Analyses focussed on feasibility outcomes and initial estimates of intervention effects to inform a future trial. The trial is registered with the ISRCTN registry 16793301. Criteria for the feasibility of trial methodology and intervention delivery were met. The trial exceeded the recruitment target, had high retention rates (87.8%) at end of treatment, and at follow up (86.6%), with good acceptability of treatment. There were 3 serious adverse events in the therapy group, and 5 in the TAU group. Improvements were evident in both groups at the end of treatment and follow up, with a particular benefit in perceived recovery in the MUSE group. We showed it was feasible to increase access to psychological intervention but a definitive trial requires further changes to the trial design or treatment

Fish and chips: Various methodologies demonstrate utility of a 16,006-gene salmonid microarray

BACKGROUND: We have developed and fabricated a salmonid microarray containing cDNAs representing 16,006 genes. The genes spotted on the array have been stringently selected from Atlantic salmon and rainbow trout expressed sequence tag (EST) databases. The EST databases presently contain over 300,000 sequences from over 175 salmonid cDNA libraries derived from a wide variety of tissues and different developmental stages. In order to evaluate the utility of the microarray, a number of hybridization techniques and screening methods have been developed and tested. RESULTS: We have analyzed and evaluated the utility of a microarray containing 16,006 (16K) salmonid cDNAs in a variety of potential experimental settings. We quantified the amount of transcriptome binding that occurred in cross-species, organ complexity and intraspecific variation hybridization studies. We also developed a methodology to rapidly identify and confirm the contents of a bacterial artificial chromosome (BAC) library containing Atlantic salmon genomic DNA. CONCLUSION: We validate and demonstrate the usefulness of the 16K microarray over a wide range of teleosts, even for transcriptome targets from species distantly related to salmonids. We show the potential of the use of the microarray in a variety of experimental settings through hybridization studies that examine the binding of targets derived from different organs and tissues. Intraspecific variation in transcriptome expression is evaluated and discussed. Finally, BAC hybridizations are demonstrated as a rapid and accurate means to identify gene content

On the Logic of a Prior Based Statistical Mechanics of Polydisperse Systems: The Case of Binary Mixtures

Most undergraduate students who have followed a thermodynamics course would have been asked to evaluate the volume occupied by one mole of air under standard conditions of pressure and temperature. However, what is this task exactly referring to? If air is to be regarded as a mixture, under what circumstances can this mixture be considered as comprising only one component called “air” in classical statistical mechanics? Furthermore, following the paradigmatic Gibbs’ mixing thought experiment, if one mixes air from a container with air from another container, all other things being equal, should there be a change in entropy? The present paper addresses these questions by developing a prior-based statistical mechanics framework to characterise binary mixtures’ composition realisations and their effect on thermodynamic free energies and entropies. It is found that (a) there exist circumstances for which an ideal binary mixture is thermodynamically equivalent to a single component ideal gas and (b) even when mixing two substances identical in their underlying composition, entropy increase does occur for finite size systems. The nature of the contributions to this increase is then discussed
