    During the 2014 legislative session, lawmakers passed the nation's most comprehensive legislation in support of English Learners (ELs). The law has three principal goals for all EL students: a) academic English proficiency, b) grade-level content knowledge, and c) multilingual skills development. Chief among the mandates is the requirement that all teachers be skilled in teaching ELs. Delivering these goals will require action at every level of the educational system: state agencies and the Board of Teaching, teacher preparation programs at institutions of higher education, school districts and charter schools, and classroom teachers and school staff.This brief examines the LEAPS (Learning for English Avademic Proficiency and Success) legislation in Minnesota, and includes the knowledge of nearly 40 experts from across Minnesota and its diverse communities who were called on to share their thoughts on how state agencies, school districts, charters, and colleges of education can rise to meet the ambitious challenge set by LEAPS

    Evaluation of a Multi-Sensor Platform in a Large-Scale Geophysical Survey at Brú na Bóinne World Heritage Site, Ireland

    This poster presents comparative results from the first use of the Geophysical Exploration Equipment Platform (GEEP) in Ireland in carrying out a multi-sensor survey in the vicinity of a possible Neolithic passage tomb known as Site E in the Brú na Bóinne World Heritage Site. Brú na Bóinne, a UNESCO World Heritage Site, has been an important ritual, social and economic centre for thousands of years. Much research has been undertaken in the area, including large-scale excavations at the Neolithic passage tombs of Newgrange and Knowth. However we still lack an in-depth understanding of the site’s broad range of archaeological monuments, and the landscape and communities that shaped them. To date there has been no systematic large-scale use of ground geophysical techniques although a number of successful spatially discrete geophysical surveys have been carried out. The landscape has many large, open fields under pasture or tillage suitable for systematic large-scale ground geophysical survey. Such a survey, integrated with the interpretation of other available remote sensing data is an obvious next step in the investigation of this internationally important landscape. The evaluation was successful and the results from the GEEP dataset will be presented with a comparative study of data collected by traditional hand-carried magnetic gradiometry, earth resistance and magnetic susceptibility surveys

    Design, modelling and preliminary characterisation of microneedle-based electrodes for tissue electroporation in vivo

    We analysed the use of microneedle-based electrodes to enhance electroporation of mouse testis with DNA vectors for production of transgenic mice. Different microneedle formats were developed and tested, and we ultimately used electrodes based on arrays of 500 μm tall microneedles. In a series of experiments involving injection of a DNA vector expressing Green Fluorescent Protein (GFP) and electroporation using microneedle electrodes and a commercially available voltage supply, we compared the performance of flat and microneedle electrodes by measuring GFP expression at various timepoints after electroporation. Our main finding, supported by both experimental and simulated data, is that needles significantly enhanced electroporation of testis

    Evaluation of ‘Eyelander’: a video game designed to engage children and young people with homonymous visual field loss in compensatory training

    Introduction: Rehabilitation can improve visual outcomes for adults with acquired homonymous visual field loss. However, it is unclear whether (re)habilitation improves visual outcomes for children because previous training schedules have been tiresome, uninteresting, and failed to keep them engaged. In this study we assessed whether children and young people with homonymous visual field loss would adhere to six weeks of unsupervised compensatory training using a specialised video game. Methods: Participants aged between 7 and 25 with homonymous visual field loss completed table-top assessments of visual search across four site visits. Two baseline assessments separated by four weeks evaluated spontaneous improvements before training began. Participants were then given a copy of the video game to use unsupervised at home for six weeks. Two follow-up assessments separated by four weeks were then conducted to evaluate immediate and acutely maintained effects of training. Results. 15 candidates met the inclusion-exclusion criteria, 9 participated, and 8 completed the study. Participants completed an average of 5.6 hours training unsupervised over the six weeks. Improvements on in-game metrics plateaued during week 3 of training. The time taken to find objects during table-top activities improved by an average of 24% (95% CI [2%, 46%]) after training. Discussion: The findings demonstrate that children and young people with homonymous visual field loss will engage with gamified compensatory training, and can improve visual outcomes with less time commitment than adults have required with non-gamified training in previous studies. Appropriately powered, randomised controlled trials are required to evaluate the validity and generalisability of observed training effects. Implications for practitioners: We conclude that (re)habilitation specialists can use specialist video games and gamification to engage children and young people with homonymous visual field loss in long-term unsupervised training schedules

    The distribution and ecology of Arenaria norvegica Gunn. in Ireland

    Get PDF
    Arenaria norvegica subsp. norvegica was re-discovered in Ireland in 2008 after an absence of 47 years. A detailed survey in 2009 revealed a small population restricted to skeletal soils on the edges of limestone pavement. A. norvegica subsp. anglica occurs in an almost identical habitat in Northern England. Irish plants also appear to flower at least a month earlier and produce more infloresences than in Britain. These differences warrant further investigation given the isolation of the Irish population. That it remained undetected for so long is remarkable and cautions against declaring a species as ‘extinct’ even in such a well botanized locality as the Burren

    Counseling versus antidepressant therapy for the treatment of mild to moderate depression in primary care: economic analysis.

    Get PDF
    OBJECTIVE: To compare the cost-effectiveness of generic psychological therapy (counseling) with routinely prescribed antidepressant drugs in a naturalistic general practice setting for a follow-up period of 12 months. METHODS: Economic analysis alongside a randomized clinical trial with patient preference arm. Comparison of depression-related health service costs at 12 months. Cost-effectiveness analysis of bootstrapped trial data using net monetary benefits and acceptability curves. RESULTS: No significant difference between the mean observed costs of patients randomized to antidepressants or to counseling (342 pounds sterling vs 302 pounds sterling , p = .56 [t test]). If decision makers are not willing to pay more for additional benefits (value placed on extra patient with good outcome, denoted by K, is zero), then we find little difference between the treatment modalities in terms of cost-effectiveness. If decision makers do place value on additional benefit (K > 0 pounds sterling), then the antidepressant group becomes more likely to be cost-effective. This likelihood is in excess of 90% where decision makers are prepared to pay an additional 2,000 pounds sterling or more per additional patient with a good global outcome. The mean values for incremental net monetary benefits (INMB) from antidepressants are substantial for higher values of K (INMB = 406 pounds sterling when K = 2,500 pounds sterling). CONCLUSION: For a small proportion of patients, the counseling intervention (as specified in this trial) is a dominant cost-effective strategy. For a larger proportion of patients, the antidepressant intervention (as specified in this trial) is the dominant cost-effective strategy. For the remaining group of patients, cost-effectiveness depends on the value of K. Since we cannot observe K, acceptability curves are a useful way to inform decision makers

    Developing ecosystem service indicators: experiences and lessons learned from sub-global assessments and other initiatives

    People depend upon ecosystems to supply a range of services necessary for their survival and well-being. Ecosystem service indicators are critical for knowing whether or not these essential services are being maintained and used in a sustainable manner, thus enabling policy makers to identify the policies and other interventions needed to better manage them. As a result, ecosystem service indicators are of increasing interest and importance to governmental and inter-governmental processes, including amongst others the Convention on Biological Diversity (CBD) and the Aichi Targets contained within its strategic plan for 2011-2020, as well as the emerging Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). Despite this growing demand, assessing ecosystem service status and trends and developing robust indicators is o!en hindered by a lack of information and data, resulting in few available indicators. In response, the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), together with a wide range of international partners and supported by the Swedish International Biodiversity Programme (SwedBio)*, undertook a project to take stock of the key lessons that have been learnt in developing and using ecosystem service indicators in a range of assessment contexts. The project examined the methodologies, metrics and data sources employed in delivering ecosystem service indicators, so as to inform future indicator development. This report presents the principal results of this project

    Citizen OBservatory WEB (COBWEB): A Generic Infrastructure Platform to Facilitate the Collection of Citizen Science Data for Environmental Monitoring

    Get PDF
    COBWEB has used the UNESCO World Network of Biosphere Reserves as a testbed for researching and developing a generic crowdsourcing infrastructure platform for environmental monitoring. A major challenge is dealing with what is necessarily a complex problem requiring sophisticated solutions balanced with the need to present sometimes unsophisticated users with comprehensible and useable software. The components of the COBWEB platform are at different Technology Readiness Levels. This short paper outlines the overall solution and points to quality assurance, standardisation and semantic interoperability as key areas requiring further attention
