Inverting recurrent neural networks for internal model control of nonlinear systems

In this paper, we show how a set of recently derived theoretical results for recurrent neural networks can be applied to the production of an internal model control system for a nonlinear plant. The results include determination of the relative order of a recurrent neural network and invertibility of such a network. A closed loop controller is produced without the need to retrain the neural network plant model. Stability of the closed-loop controller is also demonstrated.

Bioscience Horizons: the national journal of undergraduate research

Bioscience Horizons (BH)commenced publication in 2008 and features research papers and reviews written by graduating UK bioscience students. The journal is run by a consortium of UK universities (the Universities of Nottingham, Reading, Leeds and Chester) in association with Oxford University Press. Its submissions encompass the full range of subjects taught by UK bioscience departments, ranging from agronomy to zoology and including animal behaviour, cancer research, environmental biology, microbial sciences, molecular biology, pharmacolgy, primatology, taxonomy and other areas. BH receives manuscripts from recent graduates (with a bachelor of science or equivalent first degree) describing research carried out during their undergraduate studies, usually as a final-year research project. All submissions undergo expert review and have to meet strict criteria for scientific excellence and originality. Articles are written by a single author and published with the agreement of the graduate's home university department. The journal has an ISSN number and is open-access; articles are freely 'cite-able' contributions to the bioscience research literature.

The impact of educational research: alternative methodologies and conclusions

Recent controversy regarding the nature, organization and impact of educational research in the UK (Hargreaves, 1996; 1997; 1999; Hammersley, 1997; Tooley, 1998; Hillage et al., 2000; Ball, 2001) seems to devote little attention to research on the impact of educational research. This paper examines a recent Australian report (The Impact of Educational Research, DETYA, 2000) in terms of both its conclusions and its methodologies. It suggests that the impact of educational research on both policy and practice is often complex and indirect rather than linear and straightforward and that the methodologies employed in assessing such impact need to be similarly complex. Moreover, it would appear that this particular research supports Atkinson's (2000) contention that the ways in which educational research is typically produced and utilized is as part of a complex conversation about a diversity of purposes, effects and judgements rather than a more technically oriented implementation of 'what works'.

Reviewing research in education in Australia and the UK: evaluating the evaluations

In many countries concerns have been expressed about the merits of educational research. This paper reports on the outcomes of a review of reviews of such research in Australia and the UK. Taken at face value, the latest round of reviews are largely critical in the UK (where they have generated much debate) and mainly favourable in Australia (where they have not). In accounting for this difference the paper suggests that it might be explained in part as a function of how the reviews were conducted. In the UK reviews have tended to begin with the research and work forward to practice whereas in Australia they have been inclined to begin with practice and work back to the research. It is suggested that policy makers, practitioners and researchers in Australia and the UK have much to learn from each other's experience, as have those in other countries planning similar reviews.

Action research in health promotion

Objectives This article aims to define what is action research and where it fits in with health promotion practice, through drawing upon associated literature and personal action research experience. It also seeks to investigate the possible reasons why it is that health promotion researchers have not readily taken on the processes of action research strategies.

Rationale The place of action research in health promotion programmes is an important yet relatively unacknowledged and understated activity. It has proven to be very popular with other professional groups, such as in the education, management and social sciences. In terms of health service activity, it is widely established in the fields of nursing and mental health and is beginning to establish itself in medicine. While there are a few health promotion examples to draw upon, they tend to be isolated, dated and often lie outside of the mainstream literature. It is suggested that this continuing state of affairs denies many health promotion researchers a valuable resource for managing effective change in practice.

Conclusion The authors suggest that action research is both a valid and
important research method for health promotion researchers, who are advised to further consider its merits in future studies. This article draws attention to the National Health Service (NHS) South West Regional Office-commissioned Our Healthier Nation: Improving the Competence of the Workforce in Health Promotion participatory action research project, as a means of promoting and validating action research strategy. The authors were all actively involved in this project.

Genetic research in Aboriginal and Torres Strait Islander communities : continuing the conversation

Genetics is at the forefront of medical research, but it is rarely used in Indigenous health research projects. This discussion paper is the outcome of the first ever national discussion of the conduct of genetic research in Indigenous communities in Australia convened by the Lowitja Institute in 2010. It reviews the ethical issues relevant to genetic research in an Australian Indigenous context; existing guidelines for genetic research in indigenous communities internationally; and literature on genetic literacy in Indigenous contexts. Finally, the discussion paper presents a summary of the productive and challenging conversations at the round table.

Oncology service initiatives and research in regional Australia

OBJECTIVE: This paper reflects on the recent growth of cancer research being conducted through some of Australia's rural centres. It encompasses work being done across the fields of clinical, translational and health services research. DESIGN: This is a collaborative piece with contributions from rural health researchers, clinical and cancer services staff from several different regions. CONCLUSION: The past decade has seen an expansion in cancer research in rural and regional Australia driven in part by the recognition that cancer patients in remote areas experience poorer outcomes than their metropolitan counterparts. This work has led to the development of more effective cancer networks and new models of care designed to meet the particular needs of the rural cancer patient. It is hoped that the growth of cancer research in regional centres will, in time, reduce the disparity between rural and urban communities and improve outcomes for cancer patients across both populations.

Detection of Hepatozoon spp in naturally infected Brazilian dogs by polymerase chain reaction

Hepatozoon canis was molecularly identified in Rio de Janeiro State, Brazil. Twelve dogs from urban areas were studied by blood smear examination and the polymerase chain reaction (PCR) assay. From these dogs, only 1 was positive in both blood smears and PCR.

Morphology of Aortic Arch in Rabbits with Atherosclerosis Treated with Resveratrol

Objective: Atherosclerosis is a chronic inflammatory condition associated with the production of oxidative species. The phenoliccompound, resveratrol, seems to have cardioprotective activities preventing the oxidation of low-density lipoproteins.In this study we investigated the effect of resveratrol on prevention of induced atheromatosis, through the morphological study of the segment of aortic arch in White New Zealand rabbits.Study design: 20 rabbits were divided into four groups which received the following diet for 60 days: control group (CT) normal ration; resveratrol group (R) normal ration and resveratrol (3 mg/kg/day); cholesterol group (CL) 1.5% of cholesterol added to the ration; group cholesterol plus resveratrol (CR) 1.5% of cholesterol added to the ration and resveratrol (3 mg/kg/day). The analysis of the atherosclerotic lesions were performed by the means of appropriate histological techniques.Results and conclusions: The animals belonging to group CL showed atherosclerotic lesions with tunica intima thickening due to the presence of foam cells, placed in several disorganized layers, and extracellular lipid droplets in subendothelial conjunctive tissue.We also observed the invasion of foam cells in the beginning of tunica media. In animals belonging to group CR there were changes in the subendothelial of tunica intima, although in a minor degree of development as for the number of foam cells layers and extracellular lipid droplets. An invasion of foam cells in tunica media was observed in this group. We haven't seen any changes in tunica adventitia in any of the studied groups. There were not evident histological changes in any of the analised tunicas for groups CT and RConclusions: This study may help demonstrate that the phenolic compound, resveratrol, works as a preventive agent in the development of atherosclerotic lesions.
