The IMPOER project (implementation of open educational resources, OER) aimed to implement OER in a nursing programme at Dalarna University, Sweden. The university and its nursing programme have long engaged in e-learning, and the nursing programme has recently been awarded the European Association of Distance Teaching Universities E-xcellence Associates Quality Label. The quality award was based on the creation of a roadmap for the continuous development of e-learning and the implementation of OER. The results of the study illustrated that overall, the students and the educators were positive about using OER. They considered that this approach was a new way of learning, and they appreciated the fact that OER were free and easy to access. However, they felt overwhelmed by the amount of material that was available and they were concerned about quality. If the use of OER is to be sustainable, a change in attitudes and practices among students and teachers is likely needed regarding the use of resources on the web.  相似文献

Using the example of cross-cultural philosophy’s relation to disciplinary philosophy, this article seeks to think through some of the issues relevant to diversifying philosophy as an academic discipline. Guided by James Tully’s ruminations on non-domination, it attempts to make a case for a practice of philosophy which is more attuned to its social situatedness in a postindustrial, liberal society. Within this context, it argues that disciplinary philosophy must seek to contribute to making meaning of our place in the world.  相似文献

In the context of increasing commercialization of certain sports its influence on the incidence of doping in sport is often discussed. Economic incentives should influence the decision of individuals in two ways. On the one hand the amount of prize money is mentioned and on the other hand relative influences which relate to the unequal distribution of funds depending on the ranking in the competition. Based on the consideration of prize money payments in international senior competitions in two independent survey years the level and distribution of prize money in competitions will be presented. The absolute amount of the prize money explains a significant proportion of the variance in the doping affinity in the observed sports disciplines (36?%). Unequal Payouts depanding on ranking, show no significant relationship to the doping affinity. The results thus provide indications on revenue opportunities through successful participation in competitions and some empirical evidence on economic arguments in connection with the doping debate.  相似文献

Stone consolidation is one of the major restoration treatments used for historical monuments preservation. A natural stone is a complicated heterogeneous porous system making the process of consolidation dependent on many variables. In practical restoration aims, for a given stone type, the selection of a suitable consolidant and consolidation conditions therefore remains a complex issue. The impregnation depth is a key factor for the assessment of the treatment efficiency. The combination of state-of-the-art hybrid pixel semiconductor detectors with newly available micro-focus X-ray sources makes possible to apply X-ray radiography, an ideal non-destructive tool, for penetration depth monitoring. In this study, high-resolution X-ray radiography is used for monitoring the penetration depth of organosilicon consolidants in the Opuka stone. The penetration depth has been evaluated in relation to the time of consolidation, stone porosity and consolidation mixtures properties. The exact influence of the X-ray contrast agent on the consolidation depth has been investigated as well. The information obtained provides supplementary knowledge on the suitability of investigated products for the treatment of this type of stone. In our study, the capabilities of X-ray radiography have been demonstrated on X-ray radiography simple projections, high-resolution computed tomography (CT) as well as on the dynamic processes monitoring. The results thus can serve also as an instrumental and methodological example applicable for consolidation monitoring of other stone types.  相似文献

Objective: To identify or develop a critical appraisal instrument (CAI) to aid in the selection of search filters for use in systematic review searching. The CAI is to be used by experienced searchers without specialized training in statistics or search filter design. Methods: Through extensive searching and consultation, one candidate instrument was identified. Through expert consultation and several rounds of testing, the instrument was extensively revised to become the Canadian Agency for Drugs and Technologies in Health (CADTH) CAI. Results: The CADTH CAI consists of ten questions and can be applied by experienced searchers with a moderate knowledge of search filter methodology. Conclusion: The CADTH CAI provides experienced searchers with a means of selecting the search filter that is most methodologically sound.  相似文献

This paper examines how professional associations engage themselves in efforts to develop, regulate and secure knowledge in their respective domains, with special emphasis on standardisation. The general emphasis on science in society brings renewed attention to the knowledge base of professionals, and positions professional bodies as key regulatory agencies. At the same time, knowledge takes distinctive forms in different areas of expertise, and the ‘knowledge work’ of professional associations is embedded in complex settings of actors and interests that need to be negotiated. Based on documents and interviews with core representatives, we examined approaches to standardisation in three associations that represent the main bodies of nurses, teachers and auditors in Norway. The analysis shows that all associations engage themselves in efforts to develop standards for knowledge and professional practice, but that they do so in different ways and with alternative sources of legitimisation. Standardisation is initiated for variegated purposes, and involves the ongoing negotiation of tensions between different concerns. We discuss the approaches taken in relation to conditions for professionalism, and argue that the knowledge work of professional associations is becoming increasingly important in a society where knowledge, as well as the market for professional services, is becoming internationalised.  相似文献

Early detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and diagnosis of coronavirus disease 2019 (COVID-19) are priorities during the pandemic. Symptomatic and suspected asymptomatic individuals should be tested for COVID-19 to confirm infection and to be excluded from social interactions. As molecular testing capacity is overloaded during the pandemic, rapid antigen tests, such as lateral flow immunoassays (LFIAs), can be a useful tool as they allow greater test availability and obtain results in a very short time. This short review aims to present the analytical properties of LFIAs in the detection of SARS-CoV-2 in nasopharyngeal swabs. Lateral flow immunoassay is a method that combines thin-layer chromatography and indirect immunochemical sandwich method and allows the detection of a specific SARS-CoV-2 antigen in nasopharyngeal swabs. Swab specimens should be adequately collected and tested as soon as possible. Users should pay attention to quality control and possible interferences. Antigen tests for SARS-CoV-2 show high sensitivity and specificity in cases with high viral loads, and should be used up to five days after the onset of the first symptoms of COVID-19. False positive results may be obtained when screening large populations with a low prevalence of COVID-19 infection, while false negative results may happen due to improper specimen collection or insufficient amount of antigen in the specimen. So as to achieve reliable results, a diagnostic accuracy study of a specific rapid antigen test should be performed.  相似文献

This article examines relations to knowledge among novice teachers educated in a research-based program in Finland and a general professional program in Norway. The curricula of the 2 programs differ in distinct ways with regard to selection and organization of knowledge. We ask whether such differences also play out in the relations to knowledge of the 2 groups of teachers. Bernstein's concepts of knowledge discourses, classification, and framing are employed to analyze in-depth interviews with 12 teachers. The analysis revealed many similarities on the surface, but a closer examination of the teachers' use of professional language revealed significant differences. The Finnish teachers used more specialized language to frame their conceptions, and their knowledge relations reflected a stronger classification and framing than those of the Norwegian teachers. We discuss how these differences may be related to their educational programs, and the possible implications for the teachers' professional identities.  相似文献
