    In this cross-cultural collaboration, a team of Thai and American students identified strategic opportunities for Thai Public Broadcasting Service to increase public awareness and expand the audience base for its children\u27s programming. Group interviews with TPBS employees revealed the needs of the broadcaster\u27s children\u27s programming department. A comparative study of five public broadcasters --TPBS plus those of Australia, Japan, the UK, and the US-- identified expansion opportunities in three modes of public participation: community outreach activities, children\u27s websites, and Web 2.0 applications. The corresponding strategic recommendations involved development of outreach activities, design of children\u27s websites, and promotion of programming using Web 2.0

    Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) for the diagnosis of dementia within community dwelling populations

    <b>Background</b><p></p> Various tools exist for initial assessment of possible dementia with no consensus on the optimal assessment method. Instruments that use collateral sources to assess change in cognitive function over time may have particular utility. The most commonly used informant dementia assessment is the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE).<p></p> A synthesis of the available data regarding IQCODE accuracy will help inform cognitive assessment strategies for clinical practice, research and policy.<p></p> <b>Objectives</b><p></p> Our primary objective was to determine the diagnostic accuracy of the informant based questionnaire IQCODE, for detection of all cause (undifferentiated) dementia in community-dwelling adults with no previous cognitive assessment. We sought to describe the accuracy of IQCODE (the index test) against a clinical diagnosis of dementia (the reference standard).<p></p> Our secondary objective was to describe the effect of heterogeneity on the summary estimates. We were particularly interested in the traditional 26-item scale versus the 16-item short form; and language of administration. We explored the effect of varying the threshold IQCODE score used to define 'test positivity'.<p></p> <b>Search methods</b><p></p> We searched the following sources on 28 January 2013: ALOIS (Cochrane Dementia and Cognitive Improvement Group), MEDLINE (OvidSP), EMBASE (OvidSP), PsycINFO (OvidSP), BIOSIS Previews (ISI Web of Knowledge), Web of Science with Conference Proceedings (ISI Web of Knowledge), LILACS (BIREME). We also searched sources relevant or specific to diagnostic test accuracy: MEDION (Universities of Maastrict and Leuven); DARE (York University); ARIF (Birmingham University). We used sensitive search terms based on MeSH terms and other controlled vocabulary.<p></p> <b>Selection criteria</b><p></p> We selected those studies performed in community settings that used (not necessarily exclusively) the IQCODE to assess for presence of dementia and, where dementia diagnosis was confirmed, with clinical assessment. Our intention with limiting the search to a 'community' setting was to include those studies closest to population level assessment. Within our predefined community inclusion criteria, there were relevant papers that fulfilled our definition of community dwelling but represented a selected population, for example stroke survivors. We included these studies but performed sensitivity analyses to assess the effects of these less representative populations on the summary results.<p></p> <b>Data collection and analysis</b><p></p> We screened all titles generated by the electronic database searches and abstracts of all potentially relevant studies were reviewed. Full papers were assessed for eligibility and data extracted by two independent assessors. For quality assessment (risk of bias and applicability) we used the QUADAS 2 tool. We included test accuracy data on the IQCODE used at predefined diagnostic thresholds. Where data allowed, we performed meta-analyses to calculate summary values of sensitivity and specificity with corresponding 95% confidence intervals (CIs). We pre-specified analyses to describe the effect of IQCODE format (traditional or short form) and language of administration for the IQCODE.<p></p> <b>Main results</b><p></p> From 16,144 citations, 71 papers described IQCODE test accuracy. We included 10 papers (11 independent datasets) representing data from 2644 individuals (n = 379 (14%) with dementia). Using IQCODE cut-offs commonly employed in clinical practice (3.3, 3.4, 3.5, 3.6) the sensitivity and specificity of IQCODE for diagnosis of dementia across the studies were generally above 75%.<p></p> Taking an IQCODE threshold of 3.3 (or closest available) the sensitivity was 0.80 (95% CI 0.75 to 0.85); specificity was 0.84 (95% CI 0.78 to 0.90); positive likelihood ratio was 5.2 (95% CI 3.7 to 7.5) and the negative likelihood ratio was 0.23 (95% CI 0.19 to 0.29).<p></p> Comparative analysis suggested no significant difference in the test accuracy of the 16 and 26-item IQCODE tests and no significant difference in test accuracy by language of administration. There was little difference in sensitivity across our predefined diagnostic cut-points.<p></p> There was substantial heterogeneity in the included studies. Sensitivity analyses removing potentially unrepresentative populations in these studies made little difference to the pooled data estimates. The majority of included papers had potential for bias, particularly around participant selection and sampling. The quality of reporting was suboptimal particularly regarding timing of assessments and descriptors of reproducibility and inter-observer variability.<p></p> <b>Authors' conclusions</b><p></p> Published data suggest that if using the IQCODE for community dwelling older adults, the 16 item IQCODE may be preferable to the traditional scale due to lesser test burden and no obvious difference in accuracy. Although IQCODE test accuracy is in a range that many would consider 'reasonable', in the context of community or population settings the use of the IQCODE alone would result in substantial misdiagnosis and false reassurance. Across the included studies there were issues with heterogeneity, several potential biases and suboptimal reporting quality

    This paper deals with the important problem that there is no help with the accessibility evaluations of Thailand’s web by developing and evaluating a new method and tool online, WebThai2Access, with experts, developers, and users with disabilities. This tool was evaluated by 30 developers, 30 hearing impaired people, 30 visually impaired people, and 30 elderly people. The developers evaluated the websites whereas experimental tasks were given to each disabled group based on the problems they had accessing web information. The developers found WebThai2Access very usable and the 15 test criteria were reliable for evaluating websites. The lower and upper 95% limits for confidence ratings of developers were minus or plus 10% for YouTube and Pantip websites and minus or plus 3% with the blind association website. The 95% lower and upper limits of confidence were minus or plus 5% for hearing impaired users, minus or plus 2% for elderly users and minus or plus 0% for visually impaired users. The results therefore showed WebThai2Access was reliable and accessible for developers whose evaluations reasonably well predicted website accessibility for users with disabilities

    The nature of information in the 21st century : conundrums for the informatics community?

    Get PDF
    Purpose - With the proliferation of electronic information via the web a further distension of the unique characteristics of information has been witnessed. With seismic developments occurring in such a short period of time, it seems prudent to consider the very nature of information and to assess whether this accelerated growth has implications for the work of the informatics community and the information society. Design/methodology/approach - The paper begins by revisiting and refreshing the unique characteristics of information via a reappraisal of the relevant literature. These characteristics are then contextualised within the new economy and traditional economic theory. Once these unique characteristics have been examined, the author discusses how the nature of information in the twenty-first century presents the informatics community with new and difficult challenges. Findings - The challenges posed by the unique nature of information demand a definite response on the part of the informatics community, including the creation of innovative new models to accommodate information's inherent characteristics. Additionally, as the nature of information evolves yet further and ICT innovations accelerate, ever more adaptable skills will be required by the end user in order that value be derived from information. Practical implications - Outcomes and conclusions addressed in the paper may inform the informatics community generally, but will specifically inform the practice of information managers and librarians, and offer ways of assisting them in arriving at holistic decisions with respect to service provision. Originality/value - The paper is a contribution to the debate on the precise nature of information and offers new perspectives on how the informatics community should view information in the twenty-first century

    A Review of the "Digital Turn" in the New Literacy Studies

    Get PDF
    Digital communication has transformed literacy practices and assumed great importance in the functioning of workplace, recreational, and community contexts. This article reviews a decade of empirical work of the New Literacy Studies, identifying the shift toward research of digital literacy applications. The article engages with the central theoretical, methodological, and pragmatic challenges in the tradition of New Literacy Studies, while highlighting the distinctive trends in the digital strand. It identifies common patterns across new literacy practices through cross-comparisons of ethnographic research in digital media environments. It examines ways in which this research is taking into account power and pedagogy in normative contexts of literacy learning using the new media. Recommendations are given to strengthen the links between New Literacy Studies research and literacy curriculum, assessment, and accountability in the 21st century

    The Round Table on Women's Issues snapshot project: the status of women in libraries internationally

    Get PDF
    This project was commissioned by the Round Table on Women's Issues (RTWI) at the 66th IFLA conference. The Round Table on Women's Issues is a sub-division of IFLA which concerns itself extensively with questions and issues that have special relevance for women in the library profession and in the user community. Further it develops programmes designed to enhance the opportunities and the image of these two groups of women. The Round Table on Women's Issues promotes the collection, research, publication and dissemination of information on the status of women in librarianship. Another concern is to identify discrimination in all forms, and disparities in resources, programmes, and opportunities relating to women in librarianship. At the 66th Conference, members of the Round Table discussed the Association of Research Libraries' Annual Salary Survey, 1999-2000 and noted that the average salary for female directors (USD 132,000) in United States university libraries was slightly higher than the average salary of male directors (USD 125,000) (pp. 16-18). There is now the highest number of women in top administrative positions than there has been before: 54 women out of a total of 111 directorships. This was of course the good news.The bad news was that the overall salary for women in research and academic libraries in the USA was still only 94 percent that of men. During the 19 years that statistics have been gathered women have been gradually closing the earnings gap, as in 1980 they earned only 87 percent, but it is a slow process. Overall, men represent only 35 percent of the workforce among professional librarians. The Round Table felt it would be interesting to discover how this compared with salaries in other countries and other sectors. This could form the basis for some comparative statistics if other members of the group could follow up. Although aware that delegates at IFLA conferences were not representative of the profession as a whole, it was felt that it might be possible to conduct a 'snapshot' project of delegates, women officers and committee members at IFLA's 67th conference to ascertain the status of women librarians internationally. Sandra Parker and Pat Gannon-Leary from the Information Management Research Institute, University of Northumbria School of Information Studies, obtained an IFLA small grant to undertake this work and to report on findings at the 68th IFLA conference

    This article is published under a Creative Commons Attribution Non Commercial (CC BY-NC 3.0) licence that allows reuse subject only to the use being non-commercial and to the article being fully attributed (http://creativecommons.org/licenses/by-nc/3.0).Objective - To evaluate current risk models and scores for type 2 diabetes and inform selection and implementation of these in practice. Design - Systematic review using standard (quantitative) and realist (mainly qualitative) methodology. Inclusion - criteria Papers in any language describing the development or external validation, or both, of models and scores to predict the risk of an adult developing type 2 diabetes. Data sources - Medline, PreMedline, Embase, and Cochrane databases were searched. Included studies were citation tracked in Google Scholar to identify follow-on studies of usability or impact. Data extraction - Data were extracted on statistical properties of models, details of internal or external validation, and use of risk scores beyond the studies that developed them. Quantitative data were tabulated to compare model components and statistical properties. Qualitative data were analysed thematically to identify mechanisms by which use of the risk model or score might improve patient outcomes. Results - 8864 titles were scanned, 115 full text papers considered, and 43 papers included in the final sample. These described the prospective development or validation, or both, of 145 risk prediction models and scores, 94 of which were studied in detail here. They had been tested on 6.88 million participants followed for up to 28 years. Heterogeneity of primary studies precluded meta-analysis. Some but not all risk models or scores had robust statistical properties (for example, good discrimination and calibration) and had been externally validated on a different population. Genetic markers added nothing to models over clinical and sociodemographic factors. Most authors described their score as “simple” or “easily implemented,” although few were specific about the intended users and under what circumstances. Ten mechanisms were identified by which measuring diabetes risk might improve outcomes. Follow-on studies that applied a risk score as part of an intervention aimed at reducing actual risk in people were sparse. Conclusion - Much work has been done to develop diabetes risk models and scores, but most are rarely used because they require tests not routinely available or they were developed without a specific user or clear use in mind. Encouragingly, recent research has begun to tackle usability and the impact of diabetes risk scores. Two promising areas for further research are interventions that prompt lay people to check their own diabetes risk and use of risk scores on population datasets to identify high risk “hotspots” for targeted public health interventions.Tower Hamlets, Newham, and City and Hackney primary care trusts and National Institute of Health Research
