Using the example of communication about risk in a primary care setting, this paper puts forward a method of developing and evaluating a detailed search strategy for locating the literature for a systematic review of a ‘diffuse’ subject. The aim of this paper is to show how to develop a search strategy that maximizes both recall and precision while keeping search outputs manageable. Six different databases were used, namely Medline, Embase, PsychLIT, CancerLIT, Cinahl and Social Science Citation Index (SSCI). The searches were augmented by hand-searching, contacting authors, citation searching and reference lists from included papers. Other databases were searched but yielded no extra references for this subject matter. Of the 99 papers included, 80 were indexed on Medline. The Medline search strategy identified 54 of them and the remaining 26 were located on other databases. The 19 further unique references were found using the other databases and methods of retrieval. A combination of several databases must be used to maximize recall and to increase the precision of searches on individual databases, thus improving the overall efficiency of the search.  相似文献

This Digital Image Archive (DIA) project involves the production of adigital archive of a collection of Nineteenth Century photographicimages and equipment. The DIA was designed to operate as a public accesscatalogue, to aid curators with information retrieval and to reduce theneed to handle some original material. Much of the William Henry FoxTalbot collection at the Royal Photographic Society can no longer beexhibited due to damage caused by handling and light. Access to thecollection is restricted because of preservation concerns over a growingpercentage of the collection and insufficient resources forreproductions and supervision. These problems led to investigations intothe possible advantages that digital technology might offer.Cross-referencing, administrative cataloguing and recording ofpreservation techniques are ideally suited to digital technology. Theshort life span of digital storage media and concerns over systemcompatibility requires the development of a complex long-term digitalstrategy that must be standardized if the archival material is tosurvive. Construction of the DIA involved investigations into softwareand hardware configurations concentrating on the ability to customizefactors such as indexing from recognized standards and practices. Thispaper concentrates on the results of a survey into standards withindigital indexing systems, which indicates that although there is growingawareness of standardization within digital cataloguing and multimedia,many organizations continue to devise independent systems.  相似文献

Considers the experiences of designated safeguarding staff in primary aged schools (4–11 years). The study used semi-structured interviews to explore with professionals their experiences of multi-agency working to safeguard children, of factors in making decisions around reporting concerns to statutory social work services and their role in delivering early help services in one region of the U.K. Professionals raised concerns about their understanding of decisions made by social workers, but nevertheless said that these decisions affected their future reporting of safeguarding concerns. Professionals raised concern about how current safeguarding processes triage concerns around neglect, and as the effect was cumulative, felt that it could be minimised or overlooked.  相似文献

This short piece of action research seeks to identify the characteristics which ensure that the impact from external interventions delivered by Southampton Advisory Outreach Service for SEND can be sustained over time. It considers how the service can work with schools to establish self‐sustaining systems which reduce dependency, thereby freeing the service to focus resources where there is greatest need. The research suggests that sustainable progress depends on the continued setting of specific targets which allow progress to be measured and evidenced over time. It also suggests, however, that schools need to consider the wider progress made by pupils, which cannot be captured by narrow progress measures. Furthermore, the research identifies some key factors which ensure pupils continue to make progress once external support is withdrawn. These include consistency in how support is delivered, and effective communication systems that help to maintain consistent approaches to support and allow for adaptation as part of the cycle of ‘assess, plan, do and review’. The article also considers how schools retain motivation to continue with recommendations once external support is withdrawn and the conditions that are needed to foster ongoing commitment.  相似文献

No museum is actually “neutral,” ever. This article presents the keynote address presented at the annual conference of the International Committee on Museum Management (INTERCOM) and of the Federation of International Human Rights Museums (FIHRM). In it, the author lays out the provocative case that museums not only are not, but should not be “neutral” when it comes to issues of human rights and social justice. Museums need not present both sides of every argument, or retain a lofty academic tone when it comes to the injustices of the present and the past. As an alternative course, the author presents a framework published by the British Museums Association, entitled Museums Change Lives, which offers a vision for museums to engage with challenging topics. He then offers a series of examples where Museums have embraced a new role as a promoter of social good.  相似文献

The physiology of deep-water running   总被引:2,自引:0,他引:2  
Deep-water running is performed in the deep end of a swimming pool, normally with the aid of a flotation vest. The method is used for purposes of preventing injury and promoting recovery from strenuous exercise and as a form of supplementary training for cardiovascular fitness. Both stroke volume and cardiac output increase during water immersion: an increase in blood volume largely offsets the cardiac decelerating reflex at rest. At submaximal exercise intensities, blood lactate responses to exercise during deep-water running are elevated in comparison to treadmill running at a given oxygen uptake (VO2). While VO2, minute ventilation and heart rate are decreased under maximal exercise conditions in the water, deep-water running nevertheless can be justified as providing an adequate stimulus for cardiovascular training. Responses to training programmes have confirmed the efficacy of deep-water running, although positive responses are most evident when measured in a water-based test. Aerobic performance is maintained with deep-water running for up to 6 weeks in trained endurance athletes; sedentary individuals benefit more than athletes in improving maximal oxygen uptake. There is some limited evidence of improvement in anaerobic measures and in upper body strength in individuals engaging in deep-water running. A reduction in spinal loading constitutes a role for deep-water running in the prevention of injury, while an alleviation of muscle soreness confirms its value in recovery training. Further research into the applications of deep-water running to exercise therapy and athletes' training is recommended.  相似文献
