Surveys were carried out to learn more about authors and open access publishing. Awareness of open access journals among those who had not published in them was quite high; awareness of ‘self‐archiving’ was less. For open access journal authors the most important reason for publishing in that way was the principle of free access; their main concerns were grants and impact. Authors who had not published in an open access journal attributed that to unfamiliarity with such journals. Forty per cent of authors have self‐archived their traditional journal articles and almost twice as many say they would do so if required to.  相似文献

Given that biomedical innovation involves intense collaboration across disciplines, occupations and organizations, a nation's integrative capabilities (the ability to move between basic science and clinical development) and relational capabilities (the ability to collaborate with diverse organizations) have been identified as crucial. This paper deploys qualitative analysis of biomedical innovation in the UK and US to identify mechanisms influencing innovation at the project level through which these macro level capabilities may have effects. From this a propositional framework is developed that helps explain the likely impact of such capabilities for characteristically different kinds of innovation projects at the micro level.  相似文献

With many features competing for attention in their visual environment, infants must learn to deploy attention toward informative cues while ignoring distractions. Three eye tracking experiments were conducted to investigate whether 6‐ and 8‐month‐olds (total N = 102) would shift attention away from a distractor stimulus to learn a cue–reward relation. While 8‐month‐olds showed evidence of increasingly selective attention toward the predictive cues, even when the distractors were highly salient, 6‐month‐olds shifted attention toward the predictive cues only when the distractors were equally (not more) engaging. These experiments suggest that attention in infancy is highly dependent on the relative weightings of predictiveness and visual salience, which may differ across development and context.  相似文献

South Africa’s groundbreaking constitution explicitly confers a right of access to sufficient water (section 27). But the country is officially ‘water-stressed’ and around 10 % of the population still has no access to on-site or off-site piped or tap water. It is evident that a disconnect exists between this right and the reality for many; however the reasons for the continuation of such discrepancies are not always clear. While barriers to sufficient water are myriad, one significant factor contributing to insufficient and unpredictable access to water is the high percentage of broken water pumps. Previous studies have reported that between 20 and 50 % of all hand operated water pumps installed on the African continent are broken, or out of use. Monitoring and maintenance of pumps, which in South Africa is the responsibility of local municipalities is often ineffective, in part due to the distances between municipal centres and rural communities and the consequent costs of site visits, as well as breakdowns within the local bureaucratic system. The emergence of new telemetry tools that can remotely monitor water applications constitutes a novel and cost-efficient alternative to undertaking regular sites visits. Sustainable, appropriate, low-cost telemetry systems are emerging that could be used to monitor the operational performance of water pumps, or a wide range of other field parameters, and to communicate this information swiftly and cheaply to water service providers, using SMS messages. Data on the performance of water pumps could also be made available to the public online. This is an example of how ICT can be used for water resources management and environmental regulation, as well as in the governance of socio-economic rights: helping to optimize water allocation by improving communication and strengthening accountability.  相似文献

As part of the emergence of new writing practices in the social sciences, qualitative researchers have begun to harness the potential of poetic representations as a means of analysing social worlds and communicating their findings to others. To date, this genre has been little used within the domains of sport and physical education. Accordingly, in this article, we provide examples of poetic representations and seek to generate insights into the process of their construction by exploring the perspectives of their authors. A rationale for choosing this genre is outlined and the potential benefits and risks of making this choice for both the researcher and the audience are considered. It is concluded that poetic representations are a worthy addition to the analytical repertoire in qualitative research.  相似文献
