OBJECTIVES: To establish reliable estimates of the proportion of books available in formats accessible to visually impaired people; to recommend a practical method of updating the estimates. METHODS: The project had two stages. Stage one estimated the overall availability of all categories of books. The British National Bibliography (BNB) for 1999-2003 was chosen as the sampling frame. A sample of 2069 titles over the 5 years was selected using a systematic sample design. These titles were then checked for availability against the catalogues of four major producer/suppliers of materials in accessible formats. The second stage involved checking the availability of books in six genres; about 400 titles for each genre were examined. RESULTS: Of the titles selected for the overall estimate, 92 (4.4%) were found to be available in one or more accessible formats. Availability of titles in accessible formats varied greatly between categories. Adult fiction had the highest number of available publications (26.3%), least represented were cookery (1.9%) and gardening (1.8%). CONCLUSIONS: This study provided baseline figures and a methodology for the Right to Read Alliance to monitor their progress in campaigning for more books to be accessible to visually impaired people. 相似文献

Herein, we describe the development of a novel primer system that allows for the capture of double-stranded polymerase chain reaction (PCR) amplification products onto a microfluidic channel without any preliminary purification stages. We show that specially designed PCR primers consisting of the main primer sequence and an additional “tag sequence” linked through a poly(ethylene glycol) molecule can be used to generate ds-PCR amplification products tailed with ss-oligonucleotides of two forensically relevant genes (amelogenin and human c-fms (macrophage colony-stimulating factor) proto-oncogene for the CSF-1 receptor (CSF1PO). Furthermore, with a view to enriching and eluting the ds-PCR products of amplification on a capillary electrophoretic-based microfluidic device we describe the capture of the target ds-PCR products onto poly(dimethylsiloxane) microchannels modified with ss-oligonucleotide capture probes. 相似文献

The effects of serial episodes of fatigue and recovery on volitional and magnetically evoked neuromuscular performance of the knee flexors were assessed in 20 female soccer players during: (i) an intervention comprising 4 × 35 s maximal static exercise, and (ii) a control condition. Volitional peak force was impaired progressively (-16% vs. baseline: 235.3 ± 54.7 to 198.1 ± 38.5 N) by the fatiguing exercise and recovered to within -97% of baseline values following 6 min of rest. Evoked peak twitch force was diminished subsequent to the fourth episode of exercise (23.3%: 21.4 ± 13.8 vs. 16.4 ± 14.6 N) and remained impaired at this level throughout the recovery. Impairment of volitional electromechanical delay performance following the first episode of exercise (25.5%: 55.3 ± 11.9 vs. 69.5 ± 24.5 ms) contrasted with concurrent improvement (10.0%: 24.5 ± 4.7 vs. 22.1 ± 5.0 ms) in evoked electromechanical delay (P < 0.05), and this increased disparity between evoked and volitional electromechanical delay remained during subsequent periods of intervention and recovery. The fatiguing exercise provoked substantial impairments to volitional strength and volitional electromechanical delay that showed differential patterns of recovery. However, improved evoked electromechanical delay performance might identify a dormant capability for optimal muscle responses during acute stressful exercise and an improved capacity to maintain dynamic joint stability during critical episodes of loading. 相似文献

This paper explores issues relating to programmes for doctoral students wishing to gain experience of, and develop skills in, teaching. The focus is on “Developing Learning and Teaching” – a new provision at the University of Oxford. The purpose is to exemplify how activity theory can be used to situate particular programmes and individual experiences in a wider systemic setting. The authors explain the concepts of the activity system, and use these to identify systemic tensions (analysing university‐wide survey data), then to assess whether the provision has addressed these tensions (analysing data from interviews with participants). Cet article explore les questions soulevées par les programmes destinés aux doctorants intéressés à acquérir une expérience d’enseignement et à développer leurs compétences d’enseignement. Le centre d’intérêt est placé sur ? «Developing Learning and Teaching» ? – un nouveau cours offert à l’université d’Oxford. L’objectif est de démontrer comment la théorie de l’activité peut être utilisée de façon à situer des programmes spécifiques et des expériences individuelles dans un contexte systémique plus vaste. Nous expliquons les concepts du système d’activité et utilisons ceux‐ci de façon à identifier des tensions systémiques (par l’analyse de données recueillies par questionnaire à la grandeur de l’université), puis évaluons si le cours cible ces tensions (par l’analyse de données recueillies par entretien auprès des participants). 相似文献

Over the past 25 years, there has been growing investment in concepts of rights in the areas of HIV prevention, care and treatment, including HIV- and AIDS-related education delivered in schools. Despite this increasing commitment to the notion of rights, few efforts appear to have been made to understand the varying conceptions of rights that underpin different kinds of initiatives. Engaging with a multi-disciplinary body of literature on the issue of rights, and through a focus on three rights-informed HIV- and AIDS-related initiatives, this paper seeks to address this gap in the current literature. In so doing, it also examines a central tension within human rights discourse, namely between the construal of rights as shared and universally applicable to all human beings, while being created in and limited by the location in which they were elaborated, as well as by the language used to formulate them. More explicit engagement with the diversity of approaches made possible through a commitment to human rights may facilitate forms of HIV- and AIDS-related education that are more meaningful to young people. 相似文献

The aim of the study was to deepen our understanding of how related multiscreening affects audience memory and persuasion. A survey was administered after a live television show. The results showed that the higher the perceived relatedness of the multi-screen activity, the more persuasive the message. This effect was mediated by subsequent attention to television content, program involvement, and attention to the commercial break. The model was replicated for three different multiscreen activities: social media use, chatting, and information search. Furthermore, it was found that related multiscreening increased the likelihood of respondents staying tuned to the television after the show. 相似文献

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice. 相似文献

ABSTRACTThe nature of academic librarianship is changing as librarians move away from the curation of material and into research support roles. Although this creates new opportunities it can be difficult for staff to learn the skills needed. The Office of Scholarly Communication at Cambridge University seeks to address this issue with the Research Support Ambassadors Programme, an initiative which skills staff in areas such as Research Data Management and Open Access. This case study outlines the evolution of the program from its pilot through to its recently completed second run in 2016. The challenges associated with running a cross-library training program are discussed and solutions highlighted. Also discussed is the impact that the program has had on participants. This case study will be of interest to those aiming to pursue a career in this area of librarianship and those looking at preparing staff for the future of the academic library. 相似文献
