This study examined the use that older, regular users of computers make of information and computer technology in their daily lives. Opinions from such users were obtained regarding what they want these technologies to offer them in the future. By means of a discussion group and an online questionnaire, our critical case examined a group of mature senior students from the Universitat Oberta de Catalunya (online learning) who have used computers and the Internet in their activities. In general, the participants needed to know the function of the tool beforehand and to have continued support and confidence. In particular, they need the certainty that the future technology will allow them to maintain their independence and autonomy. Older people's adoption of IT needs to be treated as more than merely a question of usability. Attitudes, experience of use, and perceived benefits are also key aspects that must be taken into account. 相似文献

This paper reflects on the teaching of science fiction texts to first-year engineering students at the University of the Witwatersrand as part of a Critical Thinking course that uses literature as a vehicle through which to develop competence in critical literacy and communication. This course aims to equip engineering students, as future intermediaries between science and society, with the ability to fulfil this role in both the contemporary global world and South Africa more specifically through the imaginative inhabitation of divergent subject positions afforded by literary texts. Science fiction encourages students to engage imaginatively with various societal ideas, constructs and possibilities. One of the principles of the course is that reading facilitates empathic responses, challenging readers to inhabit unfamiliar subject positions. In this way, the teaching of science fiction aims to develop self-reflective and critical learning practices, wherein engineering students grapple with the ethical ramifications of extrapolated known science in a South African context. 相似文献

The objective of this paper is to investigate the position of the resultant force in involute spline coupling teeth due to the contact pressure distribution for both ideal and misaligned conditions. In general, spline coupling teeth are in contact all along the involute profile and the load is far from uniform along the contact line. Theoretical models available in publications consider the resultant contact force as it is applied at the pitch diameter, and this study aims to evaluate the error introduced within the confines of a common approximation environment. This analysis is carried out through using finite element method （FEM） models, considering spline couplings in both ideal and misaligned conditions. Results show that the differences between the load application diameter and pitch diameter are not very obvious in both ideal and misaligned conditions; however, this ap- proximation becomes more important for the calculation of the tooth stiffness. 相似文献

The aim of the study was to evaluate the dorsal and lumbar spine of expert and recreational tennis players before (pre) and after (post) two different training sessions. The sample consisted of 17 male tennis players, nine expert and eight recreational males (age 21.2 ± 1.6 years). We assessed the back surface by rasterstereography pre and post two different training sessions both lasting 1.5 h: a standard training and a specific over-shoulder shots training session, respectively. Lordotic and kyphotic angle, length, imbalance, inclination for trunk, pelvic torsion, left and right lateral deviation and surface rotation were measured. Tennis expertise (expert versus recreational) significantly affected the surface rotation and right lateral deviation (P < 0.05). Trunk length was affected by intervention (pre versus post) (P < 0.05). Left lateral deviation differed both for type of session (session 1 versus session 2) and intervention (P < 0.001, P < 0.05). Expert tennis players had higher values on surface rotation and right lateral deviation, around or just above physiological values (0–5° and 0–5 mm, respectively). Type of session significantly affected left lateral deviation, indicating that over-shoulder shots lead to a higher stress for the spine; the workload produced by both single sessions led to a shortening effect on trunk length. A single training session can induce acute modifications in some parameters of dorsal and lumbar spine of players. 相似文献

In its advancement towards an education quasi-market, Catalonia has recently been driving the development of school educational projects in all schools (both public and private) as a tool to facilitate school autonomy and family choices. A school educational project is a formal document in which schools identify their pedagogical goals, missions and orientations, their academic resources and organisational structures. Through the analysis of 60 in-depth interviews with parents of children at the age of commencing universal pre-primary education (three years old) and data collected from surveys completed by a representative sample made up of 3245 families, this article explores the impact of this policy on discourses and practices of school choice amongst families in the city of Barcelona. On the one hand, we observe that interest in educational projects has penetrated the discourses of the most educated parents, even though, at the same time, we detect a generalised lack of knowledge of the content of such projects. On the other hand, we note that the social composition of schools is still a prominent factor in choice practices. Such findings question the ideal of the autonomous and rational citizen-consumer that underlies the policy of establishing educational projects. 相似文献
