This paper offers an ethical framework for the development of robots as home companions that are intended to address the isolation and reduced physical functioning of frail older people with capacity, especially those living alone in a noninstitutional setting. Our ethical framework gives autonomy priority in a list of purposes served by assistive technology in general, and carebots in particular. It first introduces the notion of “presence” and draws a distinction between humanoid multi-function robots and non-humanoid robots to suggest that the former provide a more sophisticated presence than the latter. It then looks at the difference between lower-tech assistive technological support for older people and its benefits, and contrasts these with what robots can offer. This provides some context for the ethical assessment of robotic assistive technology. We then consider what might need to be added to presence to produce care from a companion robot that deals with older people’s reduced functioning and isolation. Finally, we outline and explain our ethical framework. We discuss how it combines sometimes conflicting values that the design of a carebot might incorporate, if informed by an analysis of the different roles that can be served by a companion robot. 相似文献

AbstractThis study is the first empirical investigation that has explored levels of athletic identity in elite-level English professional football. The importance of understanding athletes’ psychological well-being within professional sport has been well documented. This is especially important within the professional football industry, given the high attrition rate (Anderson, G., & Miller, R. M. (2011). The academy system in English professional football: Business value or following the herd? University of Liverpool, Management School Research Paper Series. Retrieved from http://www.liv.ac.uk/managementschool/research/working%20papers/wp201143.pdf) and distinct occupational practices (Roderick, M. (2006). The work of professional football. A labour of love? London: Routledge). A total of 168 elite youth footballers from the English professional football leagues completed the Athletic Identity Measurement Scale (AIMS). Multilevel modelling was used to examine the effect of playing level, living arrangements and year of apprentice on the total AIMS score and its subscales (i.e., social identity, exclusivity and negative affectivity). Football club explained 30% of the variance in exclusivity among players (P = .022). Mean social identity was significantly higher for those players in the first year of their apprenticeship compared to the second year (P = .025). All other effects were not statistically significant (P > .05). The novel and unique findings have practical implications in the design and implementation of career support strategies with respect to social identity. This may facilitate the maintenance of motivation over a 2-year apprenticeship and positively impact on performance levels within the professional football environment. 相似文献

Under the Raj education concentrated on reproducing a small Anglicized elite capable of administering the country. Adult education was minimal and confined to a few urban centres. After Independence Indian adult education was burdened with the project of modernization as India under Nehru and the nationalist movement desperately tried to industrialize the state according to western and soviet models. Despite the relative success of the first Five Year Plan's literacy programme, levels of funding dropped while bureaucracy and falsification of figures increased. Despite Gandhi, Indian education also suffered from elitist discourses inherited from the British Raj which assumed a ‘trickle‐down’ effect and resulted in the over‐balancing of the system towards higher education. Western experts (with the honourable exception of Frank Laubach) have tended to confirm the bias, but even Laubach's agenda raised suspicion. Only with the coming of the NAEP in 1978 was a serious attempt to redress the balance made. Subsequent radical educationists have once again taken up the banner of ‘Gandhi’ in the cause of educating the very poor and the project of modernization has given way to more needs‐based programmes. 相似文献

This article reports on a participant‐centred research project with English teachers in a senior secondary college in Melbourne, Australia. It builds on previous research (Weaven and Clark 2009, 2011), which showed a low take‐up of the opportunities to teach poetry in Victoria's senior secondary English curriculum. This study explores the reasons why teachers of English are unwilling to use poetry texts in their senior classes. The teachers who participated in this study discussed and documented their attitudes towards the teaching of poetry and explored with each other the pedagogical challenges associated with teaching poetry. Their discussions – an analysis of which forms the empirical core of this article – reveal a range of explanations for teachers' reservations about offering poetry to their students. Importantly, these teachers were able to use professional discussion as a means to consider what changes in teaching practice could be successfully developed to facilitate more time spent on the teaching of poetry in senior secondary classes. 相似文献

A multivariate, theoretical model is developed and tested topredict household telephone ownership. Factors theorized topredict telephone ownership are 1) socio-economic status/resources,2) household composition, 3) cultural background, 4) attachments,includinga) community/mobility ties, b) civic/politicalties, c) group ties, d) personal ties, e) social and institutionalalienation, and of misanthropy, 5) counter-normative behavior,6) psychological well-being, and 7) physical well-being. Theanalysis, indicates that the socio-economic factor in generaland income in particular has the largest impact. All other factorsalso have significant, independent effects with the exceptionthat some, but not all, of the attachment factors and psychologicaland physical well-being are not related to telephone ownership.Overall, non-telephone households can be characterized as marginaloutsiders. 相似文献

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique,
instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study,
the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular
velocity relative to that segment’s ISA and verify that ISA theory is a valid tool to analyse segment rotation during the
golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective
ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore,
ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that
motion about the ISA is representative of joint motion. 相似文献

The use of online learning and other software-powered technologies is on the rise in the United States, encouraged financially and politically by governmental and commercial entities. Specifically, online courses are gaining ground in K–12 public schools, schools which often purchase from third-party providers. After a decade in the New York City Department of Education as an English teacher and schools official responsible for a large-scale online learning programme, the author asks the question: How does the use of software-powered technologies like online learning affect the teaching of literature? In pursuit of this question, the author draws on concept from the field of software studies while adapting qualitative methods from multimodal studies to examine precisely how the nature of software (and the ideologies of those who create and sell it) are subtly influencing the teaching of literature. 相似文献
