Armenian teachers’ dichotomous perspectives on children with high-functioning autism

This article uses the views of student teachers and serving teachers from a post-Soviet context in order to better understand current thinking around teachers’ perceptions of children with what might be termed ‘hidden’ disabilities. Drawing on social comparison theory, and adopting a phenomenographical approach, the study explores teachers’ perspectives of autism in the Republic of Armenia, offering an insight into the impact of its social, cultural and political history. Whilst serving teachers demonstrated contrastive and downward comparisons when presented with a vignette of a young person with Asperger’s Syndrome, student teachers expressed more connective comparisons. The data suggest, then, that Armenian student teachers represent progressive attitudinal change towards individuals with disabilities. These results also shed light on how social comparison theory might be used to tease out assumptions and taken-for-granted attitudes in the global West

Internet Outreach / A Guide for Health Promoters & Peer Educators

This manual brings together the experiences of an Internet outreach project conducted by theWestern Australian AIDS Council (WAAC) and the Western Australian Centre for Health PromotionResearch (WACHPR) at Curtin University of Technology along with other selected research. It presents guidelines on the development and implementation of Internet outreach programs for health promotion practitioners and peer education workers.It is divided into sections for ease of navigation, including an overview of Internet outreach as a health promotion strategy and the CyberReach project (through the implementation of which the contents were produced). There are additional components to support agencies interested in learning more about whether Internet outreach may be a useful strategy for them in expanding the range of their current services.Who this manual is for: Anyone working in health service delivery with an interest in developing Internet-based health promotion outreach programs. Although based on a project targeting same sex attracted youth (SSAY) and men who have sex with men (MSM), we believe there are aspects applicable to health practitioners working with other groups in a range of health and human services areas

Developing research across an ITE programme

The BA (Hons) Primary Education (5-11): Inclusion with SEND (with QTS) Programme is well established and successful. Tutors strive to develop University of Cumbria teachers who: know how to shape their own learning through active research; challenge, critique and debate matters pertaining to education, pedagogy and inclusion; are inspired and equipped to engage in post-graduate study. This development starts during 'Freshers Week' and continues in each of the four years of the course

Inspiring library partnerships: Evaluation of a unique reciprocal borrowing scheme between Higher Education and local authorities in the West of England

The SWRLS Open Doors project was a partnership between LibrariesWest (led by South Gloucestershire Library Service) and UWE Bristol Library Services and funded by SWRLS (South Western Regional Library Service). The aim was to pilot a reciprocal borrowing scheme between public and academic libraries using existing cards, i.e. public library cards in the academic library and university ID cards in the public libraries. The pilot looked at the scheme in terms of the following:the ease with which it was to set up,its limitations,barriers or obstacles and how these could be overcome,how popular it was both with staff and customers (i.e. members of the public or UWE staff and students).The report details the way in which the pilot was run, considers information from other higher and further education institutions and relevant literature, looks at other schemes in the UK and outlines the issues that were identified. The users of the scheme were surveyed – staff and customers – and their responses analysed.The report concludes that the reciprocal use of existing library cards between institutions and public libraries in a geographical area:was relatively simple once set up,was appreciated by all those who participated,had few teething problems,has had no appreciable impact on the availability of academic stock to UWE students,increased public library as well as academic library usage by target groups, e.g. school students 16 years and over,enabled the public library service to provide a significantly better offer of resources to its community,especially those who needed access to specialised stock not normally available in a general public library service.The Project Board recommends that this reciprocal borrowing arrangement continues between UWE and LibrariesWest and that other similar partnerships would benefit where they are geographically linked.The partners in this project plan to continue the project and to monitor it using the statistics and data monitoring used to assess its success and to give it prominence in University and public library / schools promotional material at the start of each academic year.Further information concerning this SWRLS Open Doors reciprocal borrowing project can be obtained by looking at the project website or by emailing [email protected]

Future proofing a long-term agricultural experiment for decades to come : Relocation and redesign

We are extremely grateful to generations of staff at SRUC and its predecessor organisations (NOSCA and SAC) for maintaining the Woodlands Field experiments at Craibstone over 100 years and to I&N Campbell who carefully prepared the new site and moved the soils in July 2021. The move of the soils was funded by SRUC. The molecular analysis of the soils from the pH experiment was conducted within the Soil Biology and Soil Health (SBSH) Partnership, funded by the Agriculture and Horticulture Development Board (AHDB) and the British Beet Research Organisation (BBRO) in the United Kingdom. We also gratefully acknowledge many colleagues from research and consultancy organisations in the UK and Europe who contributed to discussions during the redesign process. Professor Tony Edwards and Dr John Baddeley were both integral to the decision to move and redesign the pH Experiment. We are grateful to Allan Lilly, James Hutton Institute for allowing us to archive soils from both Woodlands Field experiments in the National Soils Archive. Thank you to Rosie Boyko and Nicola Holden (SRUC) and John Elphinstone (FERA) for useful discussions on the new experimental designs and the manuscript.Peer reviewe

Duration and severity of Medieval drought in the Lake Tahoe Basin

This paper is not subject to U.S. copyright. The definitive version was published in Quaternary Science Reviews 30 (2011): 3269-3279, doi:10.1016/j.quascirev.2011.08.015.Droughts in the western U.S. in the past 200 years are small compared to several megadroughts that occurred during Medieval times. We reconstruct duration and magnitude of extreme droughts in the northern Sierra Nevada from hydroclimatic conditions in Fallen Leaf Lake, California. Stands of submerged trees rooted in situ below the lake surface were imaged with sidescan sonar and radiocarbon analysis yields an age estimate of ∼1250 AD. Tree-ring records and submerged paleoshoreline geomorphology suggest a Medieval low-stand of Fallen Leaf Lake lasted more than 220 years. Over eighty more trees were found lying on the lake floor at various elevations above the paleoshoreline. Water-balance calculations suggest annual precipitation was less than 60% normal from late 10th century to early 13th century AD. Hence, the lake’s shoreline dropped 40–60 m below its modern elevation. Stands of pre-Medieval trees in this lake and in Lake Tahoe suggest the region experienced severe drought at least every 650–1150 years during the mid- and late-Holocene. These observations quantify paleo-precipitation and recurrence of prolonged drought in the northern Sierra Nevada.Support for this work was provided by US Geological Survey/ Desert Research Institute under Project ID# 2003NV39B, a Geological Society of America graduate research grant and the IRIS undergraduate internship program.

Autism as a disorder of neural information processing: directions for research and targets for therapy

The broad variation in phenotypes and severities within autism spectrum disorders suggests the involvement of multiple predisposing factors, interacting in complex ways with normal developmental courses and gradients. Identification of these factors, and the common developmental path into which theyfeed, is hampered bythe large degrees of convergence from causal factors to altered brain development, and divergence from abnormal brain development into altered cognition and behaviour. Genetic, neurochemical, neuroimaging and behavioural findings on autism, as well as studies of normal development and of genetic syndromes that share symptoms with autism, offer hypotheses as to the nature of causal factors and their possible effects on the structure and dynamics of neural systems. Such alterations in neural properties may in turn perturb activity-dependent development, giving rise to a complex behavioural syndrome many steps removed from the root causes. Animal models based on genetic, neurochemical, neurophysiological, and behavioural manipulations offer the possibility of exploring these developmental processes in detail, as do human studies addressing endophenotypes beyond the diagnosis itself

Community Nurses' Judgement for the Management of Venous Leg Ulceration: A Judgement Analysis

Background: Nurses caring for the large numbers of people with leg ulceration play a key role in promoting quality in health via their diagnostic and treatment clinical judgements. In the UK, audit evidence suggests that the quality of these judgements is often sub optimal. Misdiagnosis and incorrect treatment choices are likely to affect healing rates, patients’ quality of life, patient safety and healthcare costs. Objectives: To explore the diagnostic judgements and treatment choices of UK community nurses managing venous leg ulceration. Design: A judgement analysis based on Brunswik's psychological Lens Model theory. Setting: UK community and primary care nursing services. Participants: 18 community generalist nurses working in district (home) nursing teams and general practitioner services and 18 community tissue viability specialist nurses. Methods: During 2011 and 2012, 36 nurses made diagnostic judgements and treatment choices in response to 110 clinical scenarios. Scenarios were generated from real patient cases and presented online using text and wound photographs. The consensus judgements of a panel of nurses with advanced knowledge of leg ulceration judged the same scenarios and provided a standard against which to compare the participants. Correlations and logistic regression models were constructed to generate various indices of judgement and decision “performance”: accuracy (Ra), consistency (Rs) and information use (G) and uncertainty (Re). Results: Taking uncertainty into account, nurses could theoretically have achieved a diagnostic level of accuracy of 0.63 but the nurses only achieved an accuracy of 0.48. For the treatment judgement (whether applying high compression was warranted) nurses could have achieved an accuracy of 0.88 but achieved only an accuracy of 0.49. This may have been due to the nurses giving insufficient weight to the diagnostic cues of medical history and appearance of the leg and ulcer and insufficient weight to the treatment cues of type of leg ulcer and pain. Conclusion: Clinical judgements and decisions made by nurses managing leg ulceration are complex and uncertain and some of the variability in judgements and choices can be explained by the ways in which nurses process the information and handle the uncertainties, present in clinical encounters
