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

Abstract

What and how students learn depend largely on how they think they will be assessed. This study aimed to explore medical students’ perception of the value of assessment and feedback on their learning, and how this relates to their examination performance. A mixed methods research design was adopted in which a questionnaire was developed and administered to the students to gain their perceptions of assessments. Perceptions were further explored in focus group discussions. Survey findings were correlated with students’ performance data and academic coordinators’ perceptions. Students’ perceptions of the level of difficulty of different assessments mirrored their performance in examinations, with an improvement observed in clinical assessments as students progressed through their degree. Students recognised that feedback is important to allow improvements and seek more timely, better quality and personalised feedback. Academic coordinators identified that some of the students’ suggestions are more realistic than others. Students had a positive attitude towards assessment, but emphasised the need for educators to highlight the relevance of assessment to clinical practice.  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

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

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

Since the recent global paradigm shift in the governance of higher education toward business and marketing, internationally competitive education is increasingly considered as an asset for governments. Consequently, governments started to invest in education branding and marketing their educational systems. In Finland, national interest in education branding rose especially since the country's success in the programme for international student assessment studies created a positive reputation of its basic education. In this article, the authors investigate how this reputation is transformed into a general Finnish education brand, based upon Finland's official Country Brand Report (2010). The governmental discourse on Finnish education reveals a fusion of education and national branding, which is why the authors suggest to discuss the Finnish education brand as Finnish education®. The article provides an analysis of the elements constituting the brand and opens up a critical discussion on the ethics of branding education through cultural and national characteristics.  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

Despite the crucial role that students play in formative assessment practices, student perspectives on such practices are relatively under-researched. Through a qualitative analysis of 128 reflection notes written by student teachers of English, this article investigates the students’ perceptions of formative feedback as part of portfolio assessment at two teacher education institutions in Norway. As such, it contributes to bridging the gap between research and practice. Students received peer and teacher feedback on assignments and wrote reflection notes during the semester. Findings show that students are positive towards teacher feedback and highlight the significance of teacher praise. Main objections raised against peer feedback concern the lack of constructive criticism. However, positive attitudes towards peer discussion groups suggest that they may be a more effective way of implementing peer assessment than formalised written peer commentary. Student reflections suggest that a failure to understand the task and the feedback is a possible hindrance to successfully revising assignments. Overall, students’ positive attitudes towards the portfolio process, which includes multiple drafting, suggest that students in higher education would benefit from more opportunities to revise and resubmit their work, yet they need adequate practice in providing peer feedback, and interpreting and implementing feedback in general.  相似文献

The development of self‐regulation has been studied primarily in Western middle‐class contexts and has, therefore, neglected what is known about culturally varying self‐concepts and socialization strategies. The research reported here compared the self‐regulatory competencies of German middle‐class (= 125) and rural Cameroonian Nso preschoolers (= 76) using the Marshmallow test (Mischel, 2014). Study 1 revealed that 4‐year‐old Nso children showed better delay‐of‐gratification performance than their German peers. Study 2 revealed that culture‐specific maternal socialization goals and interaction behaviors were related to delay‐of‐gratification performance. Nso mothers’ focus on hierarchical relational socialization goals and responsive control seems to support children's delay‐of‐gratification performance more than German middle‐class mothers’ emphasis on psychological autonomous socialization goals and sensitive, child‐centered parenting.  相似文献
