The ageing society poses significant challenges to Europe’s economy and society. In coming to grips with these issues, we
must be aware of their ethical dimensions. Values are the heart of the European Union, as Article 1a of the Lisbon Treaty
makes clear: “The Union is founded on the values of respect for human dignity…”. The notion of Europe as a community of values
has various important implications, including the development of inclusion policies. A special case of exclusion concerns
the gap between those people with effective access to digital and information technology and those without access to it, the
“digital divide”, which in Europe is chiefly age-related. Policies to overcome the digital divide and, more generally speaking,
e-inclusion policies addressing the ageing population raise some ethical problems. Among younger senior citizens, say those
between 65 and 80 years old, the main issues are likely to be universal access to ICT and e-participation. Among the older
senior citizens, say those more than 80 years old, the main issues are mental and physical deterioration and assistive technology.
An approach geared towards the protection of human rights could match the different needs of senior citizens and provide concrete
guidance to evaluate information technologies for them. 相似文献

Although the root-mean squared deviation (RMSD) is a popular statistical measure for evaluating country-specific item-level misfit (i.e., differential item functioning [DIF]) in international large-scale assessment, this paper shows that its sensitivity to detect misfit may depend strongly on the proficiency distribution of the considered countries. Specifically, items for which most respondents in a country have a very low (or high) probability of providing a correct answer will rarely be flagged by the RMSD as showing misfit, even if very strong DIF is present. With many international large-scale assessment initiatives moving toward covering a more heterogeneous group of countries, this raises issues for the ability of the RMSD to detect item-level misfit, especially in low-performing countries that are not well-aligned with the overall difficulty level of the test. This may put one at risk of incorrectly assuming measurement invariance to hold, and may also inflate estimated between-country difference in proficiency. The degree to which the RMSD is able to detect DIF in low-performing countries is studied using both an empirical example from PISA 2015 and a simulation study. 相似文献

Drawing on qualitative interviews with Mixed martial arts (MMA) athletes and stakeholders, this study aims to investigate the relationship between, on the one hand, MMA as a spectacle and imaginary world, and on the other, the fighters’ experiences of violence, pain and ‘the real’. Analytically, we are influenced by the literature on the spectacle and on hyperreality. The results show that athletes’ negotiations concerning the sport largely connect to a particular way of approaching violence – culturally and in terms of physical experience. On the one hand, there is a desire to portray MMA as a civilized and regulated sport. The athletes develop different strategies by which to handle or renegotiate the physical force and violence in the cage. On the other hand, however, the fighters’ bodily control and management of their fear sometimes breaks down. When the spectacle of the octagon becomes ‘real’, the legitimacy of the sport is questioned. 相似文献

This article analyses fitness professionals' perceptions and understanding of their occupational education and pedagogical pursuance, framed within the emergence of a global fitness industry. The empirical material consists of interviews with personal trainers and group fitness instructors, as well as observations in their working environment. In addition, printed material from different occupational organisations and educational companies has been included. The narratives of the fitness professionals and a case study of Les Mills are presented and analysed through the concept of the McDonaldisation of society, or more specifically of fitness culture. The results show that, even though gym and fitness franchises differ from hamburger restaurant chains, there are crucial similarities, but also differences. One can, for example, discern a tendency towards the construction of predesigned and highly monitored programmes, such as the one developed by Les Mills. Homogenisation is also apparent when looking at the body ideals produced, as fitness professionals work on their own or clients' bodies, which makes it possible to anticipate a global body ideal. The social and cultural patterns of self-regulation and self-government found in gym and fitness culture can be understood and analysed in a global context. What we find is an intriguing and complex mixture of regulation, control and standardisation, on the one hand, and a struggle to express the body, to be ‘free’ and to transgress the boundaries set by the commercial global fitness industry, on the other. 相似文献

The modern world can be described as a globalized risk society. It is characterized by increasing complexity, unpredictable consequences of techno-scientific innovations and production, and its environmental consequences. Therefore, chemistry, just like many other knowledge areas, is in an ongoing process of environmentalization. For example, green chemistry has emerged as a new chemical metadiscipline and movement. The philosophy of green chemistry was originally based on a suggestion of twelve principles for environment-friendly chemistry research and production. The present article problematizes limitations in green chemistry when it comes to education. It argues that the philosophy of green chemistry in the context of education needs to be extended with socio-critical perspectives to form educated professionals and citizens who are able to understand the complexity of the world, to make value-based decisions, and to become able to engage more thoroughly in democratic decision-making on sustainability issues. Different versions of sustainability-oriented science/chemistry education are discussed to sharpen a focus on the most complex type, which is Bildung-oriented, focusing emancipation and leading to eco-reflexive education. The term eco-reflexive is used for a problematizing stance towards the modern risk society, an understanding of the complexity of life and society and their interactions, and a responsibility for individual and collective actions towards socio-ecojustice and global sustainability. The philosophical foundation and characteristics of eco-reflexive science education are sketched on in the article. 相似文献

Abstract Time-motion analyses and physiological measurements were performed to investigate the physiological demands of football referees (n = 15) and assistant referees (n = 15) in international games and to examine whether high-intensity running (HIR) correlates to the referees' ability to keep up with play. Total distance covered (10.27 ± 0.90 vs. 6.76 ± 0.83 km) and HIR (1.92 ± 0.58 vs. 0.97 ± 0.22 km) was higher (P < 0.05) for referees than assistant referees, while sprinting distance was not different. Referees covered 0.89 ± 0.37 km by backwards running and assistant referees covered 1.54 ± 0.66 km by sideways running. Mean heart rate was higher (P < 0.05) for referees than assistant referees (150 ± 3 vs. 123 ± 3 b.p.m.), whereas blood lactate was not different. Backwards/sideways running decreased (P < 0.05) from the first to the last 15-min period for referees (49%) and assistant referees (42%), whereas HIR was unaltered. HIR was inversely correlated with the five highest distances from infringements in both halves (r = ?0.60 and ?0.58, P < 0.05). In conclusion, international match officials carry out an important amount of HIR throughout games, while low-intensity and unorthodox running activities are reduced during games. Referees performing the most high-intensity work are better to keep up with play. The match activities differ significantly between referees and assistant referees, which should be considered in training and testing procedures. 相似文献

There is a general consensus among researchers and teacher educators that classroom video can be a valuable tool for pre-service teacher education. Media such as video are not, however, in themselves effective. They have to be embedded in an instructional program to be useful. Yet, little empirical research examines how specific instructional approaches might effectively exploit the potential of video in teacher education. In this study we explored the use of two video-based university courses, one representing a cognitive instructional strategy integrating video, the other representing a situative strategy. Using data from learning journals we analyzed the effects of the two strategies on pre-service teachers’ (N = 28) ability to reflect on classroom video. We found that the two strategies have distinct impacts on the kinds of reflection patterns that are fostered. Our findings suggest that the learning goal and purpose at hand should determine which instructional strategy should be employed when embedding classroom video into teacher education courses. 相似文献

This paper aims to investigate the marketization of higher education (HE) as it manifests itself in the concept of Student life on Danish HE websites. Taking Norman Fairclough’s critical discourse analysis as its starting point, this paper critically examines this particular practice of marketization by making a single-case study of the pages called Student life at the biggest university in Denmark, Copenhagen University (CU). The findings show that these page elements of social life are intensively and routinely used to soften up the more demanding aspects of being a university student, and that this involves a significant positive evaluation of life as a university student. The paper addresses the potential problems related to the findings in order to contribute to further discussion and reflection upon issues centred around the marketization of HE on university websites and around the construction of what it means to be a student today. 相似文献
