Web 2.0 innovations may enhance informed patient decision-making, but also raise ethical concerns about inaccurate or misleading information, damage to the doctor-patient relationship, privacy and confidentiality, and health disparities. To increase the benefits and decrease the risks of these innovations, we recommend steps to help patients assess the quality of health information on the Internet; promote constructive doctor-patient communication about new information technologies; and set standards for privacy and data security in patient-controlled health records and for point-of-service advertising.  相似文献

Abstract

A number of major organisations have, over the last five years or so, become involved in offering advice on the taking and use of photographs of children. The Information Commissioner's Office, for example, has issued guidance on the legal situation surrounding the photographing of children and the NSPCC has drawn up recommendations, for community groups, concerning the placement of children's photographs on websites.  相似文献

Abstract

Situated learning, focusing on the pragmatic and social aspects of learning, has as its basis the notion that learning is essentially dependent on the immediate situation of action. It is a strength of the theory that it supports learner‐centred instructional design (ID), and supports a constructivist approach to ID. Nevertheless, even a learner‐centred theory such as situated learning requires more if its product is to be successful in facilitating learning. Student learning requires management at every level: within individual learning activities, within a module syllabus and within a curriculum. The contextual issues which go to make up such management, and the relations between situated learning theory and learning management, are the focus of this paper. We shall argue that it is essential for the success of embedded IT that instructional designers pay attention to learning management issues, that they signal the presence of these issues in their courseware documentation, and that lecturers and tutors who use the courseware should take these issues into account when implementing and embedding computer‐based learning in the curriculum.

As an example of this argument we take our computer‐based learning program the Virtual Court Action. This program was designed to be used in the learning and teaching of procedural law in a Scottish university law curriculum. Using document assembly techniques and email, this program emulates part of a civil court action in a Scottish court, with identical personnel, legal documents and procedure. The place of situated learning theory in its design is described, and the learning management issues germane to its implementation are analysed. Finally, we show how the attention paid to learning management issues contributed to the success of the program.

‘Acting on the world to learn about concepts is not a straightforward issue.‘1

‘Old‐fashioned pocket knives … have a device for removing stones from horses’ hooves. People with this device may know its use and be able to talk wisely about horses, hooves and stones. But they may never betray ‐ or even recognise ‐ that they would not begin to know how to use this implement on a horse.‘2  相似文献

By considering cultural practices and preferences in terms of intra-individual behavioral variation it is possible to construct a model of the social world which does not neglect individual singularities and avoids the cultural caricature of social groups. Thus, it becomes clear that the boundary between ??cultural legitimacy?? and ??cultural illegitimacy?? does not only separate different social classes, but divides up the cultural practices and preferences of individuals themselves across all classes. Without challenging the existence of social inequalities in terms of the most legitimate forms of culture, such a scientific point of view allows to establish the marked statistical frequency of individual cultural profiles composed of heterogeneous or dissonant elements. The article considers the socio-historical conditions that produce heterogeneous cultural profiles and shows that these frequent cultural dissonances allow to reinterpret the social functions of culture and to highlight the importance of the study of intra-individual behavioral variations within the framework of a sociology of dispositional and contextual plurality.  相似文献

The deadlock in the WTO Doha Round has been accompanied by an increased focus on the negotiation of preferential trade agreements, including so-called ‘mega-regionals’. This paper discusses possible implications for—and possible responses by—excluded countries that have little prospects of participating in most of the mega-regionals. A number of complementary avenues are identified through which such countries might attenuate the potential downsides of preferential trade liberalization among large countries, as well as some proposals that would expand the scope to pursue cooperation on regulatory policies in the WTO as opposed to PTAs.  相似文献

In The Calculus of Consent (1962: 235) Buchanan and Tullock assert: (1)?ceteris paribus, while a coalition controlling less than a majority of voters may control in either chamber, the greater the difference in the bases of representation in the two houses, the less likely is any given coalition of voters to control a majority of the seats in both chambers; (2)?the potential of cross-chamber logrolls (on issues of unequal intensity) increases the likelihood that a minority may effectively control policy making. We link these ideas to social theory approaches to bicameralism and for the empirical study of legislatures.  相似文献
