It has become commonplace to hold the view that virtual surrogates for the things that are good in life are inferior to their actual, authentic counterparts, including virtual education, virtual skill-demanding activities and virtual acts of creativity. Virtual friendship has also been argued to be inferior to traditional, embodied forms of friendship. Coupled with the view that virtual friendships threaten to replace actual ones, the conclusion is often made that we ought to concentrate our efforts on actual friendships rather than settle for virtual replacements. The purpose of this paper is to offer a balanced and empirically grounded analysis of the relative prudential value of actual and virtual friendship. That is, do actual and virtual friendships differ when it comes to enhancing our subjective well-being? In doing so, I will discuss a number of presuppositions that lie behind common criticisms of virtual friendship. This will include, among other considerations, their potential for replacing actual friendship, as well as the possibility for self-disclosure, trust, sharing and dynamic spread of happiness in virtual worlds. The purpose is not to arrive at a firm, normative conclusion, but rather to introduce a number of considerations that we should take into account in our individual deliberations over which role virtual friendships ought to have in our unique life situations. 相似文献

Recently, there has been a heavy debate in the US about the government’s use of data mining in its fight against terrorism.
Privacy concerns in fact led the Congress to terminate the funding of TIA, a program for advanced information technology to
be used in the combat of terrorism. The arguments put forward in this debate, more specifically those found in the main report
and minority report by the TAPAC established by the Secretary of Defense to examine the TIA issue, will be analysed to trace
the deeper roots of this controversy. This analysis will in turn be used as a test case to examine the adequacy of the usual
theoretical frameworks for these kinds of issues, in particular the notion of privacy. Whereas the dominant theoretical framing
of the notion of privacy turns around access to information, most of the core arguments in the debate do not fit in this kind of framework. The basic disagreements in
the controversy are not about mere access, they involve both access and use. Furthermore, whereas the issue of access by itself refers to a more or less static situation, the real disagreements much
more concern the organisational dynamics of the use of information, the mechanisms in the organisation that control these
dynamics, and the awareness present within the organisation of the ‘social risks’ these dynamics represent. The bottom line
question is whether the assessment of these gives sufficient reason for trust. 相似文献

This paper deals with intercultural aspects of privacy, particularly with regard to important differences between Japanese
and the Western views. This paper is based on our discussions with Rafael Capurro – a dialogue now represented by two separate
but closely interrelated articles. The companion paper is broadly focused on the cultural and historical backgrounds of the
concepts of privacy and individualism in “Western” worlds; our main theme focuses on different concepts of privacy in Japan
and their sources in related aspects of Japanese culture. The interrelationship between our two papers is apparent in our
taking up identical or similar topics in each paper. Reading our two papers in conjunction with each other will bring about
deeper and broader insights into the diverse values and worldviews of Japan and Western cultures that underlie concepts of
privacy that at a surface level appear to be similar 相似文献

Today all parties within the health-care system demand more information and evidence to take more efficient and pinpointed management decisions. Their goal is a better patient and patient-care management. This paper presents an information visualisation approach to discover knowledge for the management of tele-home care for the elderly using the video-telephone: what type of elderly need what type of video-telephone interventions? This document focuses on the synthesis aspects of data mining with a view to knowledge discovery: the global, holistic, synthesis approach. More specifically, it summarises visually the relationships among the types of video-telephony care, among the segments of elderly, and between the types of interventions and the segments of elderly simultaneously. The graphical display allows delineating areas that group elderly with a similar/dissimilar video-telephony care profile. Information visualisation is a promising approach to provide insight into large multidimensional data sets. It fosters knowledge discovery. 相似文献

This article argues that test takers are as integral to determining validity of test scores as defining target content and conditioning inferences on test use. A principled sustained attention to how students interact with assessment opportunities is essential, as is a principled sustained evaluation of evidence confirming the validity or calling into question the inferences for individual students. Three innovative assessment systems are highlighted to illustrate where and how the developers might handle diverse test taker needs and learning characteristics. ONPAR measures challenging content using multisemiotic methods and novel item types, designing items to handle multiple profiles so they are accessible for most students. Dynamic Learning Maps has built an innovative network of learning maps, and multiple pathways designed to model how diverse students acquire knowledge. To support their assessments, the National Center and State Collaborative has built an exemplary web of educator resources such as content modules and guides in order to support differentiated learning. 相似文献

Aidan Chambers’ Breaktime (1978) is famous for its unique narrative style and sexual content. This focus has obscured another significant aspect of the novel: the role of social class in Breaktime and Chambers’ working-class background have rarely been explored. Chambers was an example of what Richard Hoggart calls “the scholarship boy,” a working-class boy educated in a grammar school in mid-twentieth-century Britain. In this article, Haru Takiuchi argues that Chambers’ scholarship-boy experiences are crucial for understanding Breaktime. For his analysis of the cultural and psychological aspects of class that concern representations of scholarship boys in British children’s literature of the 1960s and 1970s, he draws on Pierre Bourdieu’s theory of class habitus, more focused studies of class in Britain and research into the experiences of scholarship boys. Using material from the author’s archive supplemented with interviews, Haru Takiuchi highlights Chambers’ unique representation of the scholarship boy and social class in the book. 相似文献

The extraordinary romance and thrilling adventure associated with the tale of wootz steel shows how Indian metallurgists were
the world leaders in antiquity in the manufacture of this legendary high-grade steel. In many ways this material was brought
to global attention by the writings of Cyril Stanley Smith. Modern metallurgy and materials science rest on the foundation
built by the study of this steel during the past three centuries. 相似文献

This report describes a mail survey of general early educators from Head Start, public school pre-kindergarten, public school kindergarten, and community preschool/child care programs. The purposes were to secure information about the availability of classroom activities and areas, and to obtain the respondents' perceptions of the ease with which activities and areas could be adapted to accommodate children with disabilities. Of the 893 mailed questionnaires, 483 (54.1%) were returned and coded. The respondents reportedly used a wide range of classroom activities and areas, and they rated those activities and areas as moderately easy to adapt. Also, respondents from mainstreamed programs used slightly more activities and perceived the activities as easier to adapt than did respondents from non-mainstreamed programs. The findings appear to indicate that placement of children with disabilities in segregated programs cannot be justified on grounds that integration will restrict the range of activities available to typically developing children, or on the grounds that the adaptations are perceived by program staff as too difficult to be accomplished. 相似文献
