VegMachine.net. Online land cover analysis for the rangelands

VegMachine.net is an online land cover monitoring tool unded by the Fitzroy Basin Association (FBA). The tool focuses primarily on Queensland, but has functionality for much of Australia’s rangelands. The website went live in July 2016 and recently logged the 1000th user session. Users can view seven different seasonal time series of cover products across the landscape and interactively interrogate and graph ground cover change in six different on-the-fly and email delivered reports. Results can then be exported for use in other software. To date, users have generated over 400 VegMachine® FORAGE ground cover reports which provide paddock-by-paddock, landtype-by-landtype analysis of ground cover change from 1990 to the present. Detailed help is available in multiple formats, including website popups and a dedicated YouTube channel. The web application was designed for two main user groups; technically equipped RD&E personnel including those servicing land manager clients, and a subset of the grazier community willing to operate the service themselves. Initial rollout of the application focused primarily on training events for government agency, private consultancy and natural resource management (NRM) staff in regional Queensland. These users form the core of the current user base. In this paper, we outline the development of VegMachine.net. We demonstrate the primary functionality of the website, provide an overview of user experience including a case study and discuss major learnings and future directions

Identifying needs-based groupings among people accessing intellectual disability services

There is increasing emphasis on needs-led service-provision for people with intellectual disability (ID). This study outlines the statistical cluster analysis of clinical data from 1692 individuals accessing UK secondary care ID services. Using objective needs assessment data from a newly developed ID assessment tool, six clusters were identified. These had clinical face validity and were validated using six concurrently (but independently) rated tools. In keeping with previous studies, the clusters varied in terms of overall level of need as well as specific clinical features (autism spectrum disorder, mental health problems, challenging behaviors and physical health conditions). More work is now needed to further develop these clusters and explore their utility for planning, commissioning and optimizing needs-led services

Spillover and work-family conflict in probation practice: Managing the boundary between work and home life

Based on the close relationship between social work and probation practice this article uses and develops Greenhaus and Beutell's (1985) work-family conflict model to understand the spillover from probation work to practitioners’ family lives. We examine the ways spillover affects practitioners' family lives and show that these conflicts stem from desensitisation and the work being community based. They also arise in more imagined ways which we describe as altruistic imaginings and darker imaginings. The article concludes by highlighting the need for organisations to acknowledge spillover and its effects and makes suggestions around the provision of organisational policies. We conclude by considering what probation providers, as employers might do improve the situation as well as some reflective tools that practitioners might use to consider their own work-life balance with a view to improving staff wellbeing as well as effective service provision

The changing of the guard: groupwork with people who have intellectual disabilities

This paper considers the impact of service systems on group activities. It describes an inter-professional groupwork project facilitated by a social worker and a community nurse. The project provided an emancipatory experience for a group of adults who had intellectual disabilities. The group was charged with the task of reviewing and updating the recruitment and interview processes used by a 'Learning Disability Partnership Board', when employing new support workers. The paper begins with a brief history of intellectual disability and provides a context to the underpinning philosophical belief that people should be encouraged and supported to inhabit valued social roles no matter what disability they may have. It then identifies the ways in which the sponsoring health, education and social care services impacted on the creation and development of a groupwork project. It might have been expected that the nature of the intellectual disability would have been the major influence on group process. However the paper reveals that organisational constraints had a significant impact on group functioning. Issues including, staffing budgets and transport contracts impacted on group process and function. The results of the project show how, with adequate support, people with intellectual disability can make important decisions that have long-reaching impacts on the services

Radiation Cataractogenesis Induced by Neutron or Gamma Irradiation in the Rat Lens is Reduced by Vitamin E

Although cataract of the eye lens is a known late effect of ionizing radiation exposure, most of the experimental work to date has concentrated on single, acute high doses or multiple, fractionated, chronic exposures. Many papers have dealt with biochemical alterations in metabolism and cellular components, with microscopic and electron microscopic lesions to the epithelial and cortical layers, and with clinical cataract formation. However, the minimum cataractogenic dose for rats has for many years been considered to be about 2 Gy for a single, acute dose of low LET radiation. Our purpose in designing this pilot study was three fold: firstly, to determine whether any physical damage could be detected after low, acute exposure to neutron radiation (10 and 100 cGy); secondly, to compare the relative effectiveness of fast (14 MeV) neutrons with gamma-rays; and thirdly, to investigate the possibility that vitamin E could protect the lenses from radiation damage. The results revealed that morphological damage was already discernible within minutes after exposure to neutrons or gamma-rays, that it became greater after 24 hours, that neutrons were more damaging than gamma-rays, and that vitamin E could effectively reduce the cataractogenic damage induced by ionizing radiation. Control, non-irradiated lenses with or without vitamin E, either in vivo or in vitro, showed no damage. Also, it appeared that in vitro irradiation was more damaging to lenses than in vivo irradiation, so this culture technique may prove to be a sensitive tool for assessing early damage caused by ionizing radiation. However it must be noted that at this level of radiation exposure (10-100 cGy), the early damage we have described will probably be repaired so no clinical cataracts will develop, unless other factors contribute to their development

VegMachine.net. online land cover analysis for the Australian rangelands

This paper documents the development and use of the VegMachine.net land cover monitoring tool. From 2002 to 2015, VegMachine® software was used by government agencies, natural resource management (NRM) groups and individual pastoralists in northern Australia to assess and benchmark vegetation cover levels. In 2016 the VegMachine.net website was launched to build a wider user base and assure service continuity. Users can now graph historical (1990-) cover on one or more user defined areas of interest (AOI), produce comprehensive paddock-by-paddock property monitoring reports, and view a range of land cover raster images through the website map panel. In its first 32 months of operation 913 users logged 1604 sessions on the website and more than 1000 of the website's most comprehensive monitoring reports were distributed to users. Levels of use varied 26% of users (n = 237) have used the website more than once, and within this group a smaller set of regular users (n = 36) have used the site more than five times, in many cases to provide analyses to multiple clients. We outline four case studies that document the significant impact VegMachine.net has had on users including graziers, government agencies, NRM groups and researchers. We also discuss some possible paths forward that could widen the user base and improve retention of first time users. © 2019 The State of Queensland (through the Department of Agriculture and Fisheries) 2019 Open Access

Reduction of Sunburn Damage to Skin by Topical Application of Vitamin E Acetate Following Exposure to Ultraviolet B Radiation: Effect of Delaying Application or of Reducing Concentration of Vitamin E Acetate Applied

The skin of the skh-1 mouse after ultraviolet B (280-320 nm, UVB) irradiation shows the pathological changes typical of sunburn damage: spongiosis (edematous spaces) around some cells, necrosis of keratinocytes, giving rise to sunburn cells, inflammatory infiltration ofpolymorphonuclear leucocytes, etc. In our previous study, these were accompanied by erythema, increased skin sensitivity, and edematous swelling. The topical application of tocopherol acetate (TA) immediately after the UVB exposure decreased these changes. In this paper, multiple measurements of the skin thickness were made at different locations along the magnetic resonance imaging (MRI) cross-sectional image of the skin. This permits effects to be quantified with (if desired) the contralateral half of the back serving as an internal control, either exposed (positive control) or unexposed (negative control). Topical application of TA resulted in an increase in the concentration of free tocopherol in the skin. No qualitative differences in ultrastructural appearance of the DVB-irradiated, TA-treated skin could be discerned by careful examination. In vivo high resolution video microscopy of blood flow in venules of the irradiated mouse ear revealed a large (tenfold) but not statistically significant decrease in stationary lymphocytes adhering to the venule walls. The delaying of the application of TA up to 8 hours after the termination of UVB irradiation still offered statistically significant protection as did immediate application of 5% TA in diluent Myritol 318 (Delios S, Henkel)
