Unhealthy landscapes: policy recommendations on land use change and infectious disease emergence

Anthropogenic land use changes drive a range of infectious disease outbreaks and emergence events and modify the transmission of endemic infections. These drivers include agricultural encroachment, deforestation, road construction, dam building, irrigation, wetland modification, mining, the concentration or expansion of urban environments, coastal zone degradation, and other activities. These changes in turn cause a cascade of factors that exacerbate infectious disease emergence, such as forest fragmentation, disease introduction, pollution, poverty, and human migration. The Working Group on Land Use Change and Disease Emergence grew out of a special colloquium that convened international experts in infectious diseases, ecology, and environmental health to assess the current state of knowledge and to develop recommendations for addressing these environmental health challenges. The group established a systems model approach and priority lists of infectious diseases affected by ecologic degradation. Policy-relevant levels of the model include specific health risk factors, landscape or habitat change, and institutional (economic and behavioral) levels. The group recommended creating Centers of Excellence in Ecology and Health Research and Training, based at regional universities and/or research institutes with close links to the surrounding communities. The centers' objectives would be 3-fold: a) to provide information to local communities about the links between environmental change and public health ; b) to facilitate fully interdisciplinary research from a variety of natural, social, and health sciences and train professionals who can conduct interdisciplinary research ; and c) to engage in science-based communication and assessment for policy making toward sustainable health and ecosystems.

New visions for addressing sustainability

Attaining sustainability will require concerted interactive efforts among disciplines, many of which have not yet recognized, and internalized, the relevance of environmental issues to their main intellectual discourse. The inability of key scientific disciplines to engage interactively is an obstacle to the actual attainment of sustainability. For example, in the list of Millennium Development Coals from the United Nations World Summit on Sustainable Development, Johannesburg, 2002, the seventh of the eight goals, to "ensure environmental sustainability," is presented separately from the parallel goals of reducing fertility and poverty, improving gains in equity, improving material conditions, and enhancing population health. A more integrated and consilient approach to sustainability is urgently needed.

On detecting differences between groups

Understanding the differences between contrasting groups is a fundamental task in data analysis. This realization has led to the development of a new special purpose data mining technique, contrast-set mining. We undertook a study with a retail collaborator to compare contrast-set mining with existing rule-discovery techniques. To our surprise we ob- served that straightforward application of an existing commercial rule-discovery system, Magnum Opus, could successfully perform the contrast-set-mining task. This led to the realization that contrast-set mining is a special case of the more general rule-discovery task. We present the results of our study together with a proof of this conclusion.

A guide to interviewing children : essential skills for counsellors, police, lawyers and social workers

This book has been written by two people who really understand children. [They show how to] create opportunities to reduce the trauma of the interview and significantly improve the quality of the information obtained. Chief Constable A.J. Butler Gloucestershire Constabulary A few years ago, a Chief Justice said that it was unnecessary to educate lawyers and judges in the techniques of interviewing children because it was 'just common sense'. The authors show that successful interviewing requires much more than 'common sense'. Freda Briggs, Professor of Child Development, University of South Australia...an excellent book for students and professionals in forensic psychology, policing and social work.Helen Westcott, PhD, The Open UniversityIt is critical that children are interviewed properly in cases of suspected abuse or where the children may be witnesses to or victims of a crime. Poor questioning can upset the child further and contaminate evidence that may be needed in court. Interviewing Children is a practical guide to interviewing techniques for a range of professionals including welfare workers, psychologists, schoolteachers and counsellors, police officers and lawyers. Step by step, it outlines the key stages of an interview, and how to respond to the child's needs during an interview. It explains how to deal with children of different ages and from different backgrounds, and also how to work with their parents. Particular attention is paid to the sensitive issue of sexual abuse, and the problems created by multiple interviews.Clare Wilson lectures in the Department of Psychology at the University of Sydney. Martine Powell lectures in the School of Psychology at Deakin University. Both have trained police officers, social workers and legal professionals in interviewing techniques in Australia and the UK.------------------Full quotes to go on half-title page:This book has been written by two people who really understand children.

Ecosystems and human well-being : health synthesis

This report synthesizes the findings from the Millennium Ecosystem Assessment's (MA) global and sub-global assessments of how ecosystem changes do, or could, affect human health and well-being. Main topics covered are: Food, fresh water, timber, fibre, and fuel, nutrient and waste management, pollution, processing and detoxification, cultural, spiritual and recreational services, climate regulation, and extreme weather events.

Double moves

"The more a practice is mastered, the more fully subjection is achieved. Submission and mastery take place simultaneously, and this paradoxical simultaneity constitutes the ambivalence of subjection" (Butler, 1997, p. 116).

In this paper, this quotation from Judith Butler is used as a framework for an analysis of the construction of the subject within the texts of the Queensland English Syllabus. Dr Honan describes the ways in which the rationalities of the syllabus construct this ambivalent subject position, of a subject who is at one and the same time, required to master the practices of literacy mandated in the syllabus, while becoming subjected to the requirements of these practices. In her recently completed doctoral thesis, Dr Honan found that the Queensland English Syllabus works as a governing mechanism, where "to govern, in this sense, is to structure the possible field of action of others" (Foucault, 1982, p 221). This governing works to construct the 'double' subject Judith Butler refers to who must, necessarily at one and the same time, be master of certain literacy practices, and submit to these practices.

Expression of natriuretic peptide receptor mRNA and functional response to atrial natriuretic peptide and C-type natriuretic peptide in rainbow trout (Oncorhynchus mykiss) head kidney leucocytes

The stimulatory effect of vasomodulatory natriuretic peptide hormones on macrophages and peripheral blood leucocytes in mammals is well-established. However, the relationship in lower vertebrates has not been characterised. Expression of atrial natriuretic peptide, ventricular natriuretic peptide and C-type natriuretic peptide-1, and the guanylyl cyclase-linked (GC) natriuretic peptide receptor-A and -B-type receptors (NPR-A and NPR-B, respectively) was determined by PCR from the mRNA of rainbow trout head kidney leucocytes yielding gene fragments with 100% homology to the same respective natriuretic peptide and NPR-A and -B sequences obtained from other rainbow trout tissues. A mixed population of isolated rainbow trout head kidney leucocytes was stimulated in vitro with trout atrial natriuretic peptide (specific NPR-A agonist) and trout C-type natriuretic peptide (NPR-A and -B agonist) as well as the cGMP agonist 8-bromo-cGMP or the GC inhibitor 8-bromo-phenyl-eutheno-cGMP. Respiratory burst was stimulated by trout atrial natriuretic peptide, trout C-type natriuretic peptide-1 and 8-bromo-cGMP in a dose dependant manner with the highest activity as a result of stimulation with trout C-type natriuretic peptide-1 in excess of that achieved by phorbol myristate acetate (PMA). Equimolar concentrations of the inhibitor, inhibited the respiratory burst caused by the natriuretic peptides and 8-bromo-cGMP. The natriuretic peptide receptors on rainbow trout head kidney leucocytes appear to have a stimulatory function with regard to respiratory burst that is activated through a cGMP second messenger pathway and the natriuretic peptides expressed in the head kidney leucocytes may well act in a paracrine/autocrine manner.

Unfixing knowledges : queering the literacy curriculum

In the literacy classroom, students have few opportunities to use their literacy practices to contest narratives of race, class, gender and sexuality. Instead, extensive time is spent completing literacy activities associated with what “good” readers and writers do. Students’ literacy practices are often formulaic, repetitive, and serve classroom management strategies producing a mythic narrative of good literacy teaching. This paper introduces a queer literacy curriculum that poses pedagogy as a series of questions: What does being taught, what does knowledge do to students? How does knowledge become understood in the relationship between teacher/text and student? (Lusted, 1986) It emphasizes developing critical analyses of heterosexism, heteronormativity and normativity with the goal of helping students understand binary categories are not givens, rather social constructions we are often forced to perform (Butler, 1990) through available discourses. The paper highlights an interruption into the literacy curriculum where, through collective memory work, students investigated, analysed and contested the usually-not-noticed ways a small understanding of heterosexuality has come to structure their lives.

Polyunsaturated fats in meat from Merino, first- and second-cross sheep slaughtered as yearlings

This study examined the level of long chain omega-3 and omega-6 polyunsaturated fats, the ratio of polyunsaturated fat to saturated fat (PUFA/SFA) and the ratio of omega-6 to omega-3 (n-6/n-3) fat in sheep grown under grazing conditions in Australia. The sheep genotypes used were Poll Dorset_growth × Border Leicester Merino (PDg × BLM), Poll Dorset_growth × Merino (PDg × M), Poll Dorsetmuscling × Merino (PDm × M), Border Leicester × Merino (BL × M) and Merino × Merino (M × M). Loin muscles (Longissimus lumborum) collected from 40 ewe and wether sheep slaughtered at 14 months of age were processed for fatty acid determination. After frozen storage, 20 g samples were minced and a 7 g homogenate was processed for muscle lipid extraction using a chloroform:methanol (2:1) procedure. There was an increase in PUFA/SFA as the proportion of Merino genetics increased in the progeny (second-cross < first-cross < Merino), but this was not shown in the n-6/n-3 ratio. The PUFA/SFA trend appeared to be associated with an increase in the level of total polyunsaturated fats, but not a decrease in the level of total saturated fats. The results demonstrate that there is a need to improve the PUFA/SFA content in first- and second-cross animals which are mainly used for meat production in Australia so as to maintain the healthy lipids in meat. Nutritional manipulation through feeding systems or selection of sires for greater heritability of omega-3 fat deposition may be suitable pathways to elevate the ratio of polyunsaturated fatty acids, and in particular omega-3.
