This paper explores city break tourism and, in particular, the distinctive characteristics of this form of travel. The city break is examined and compared with other types of trips. The research follows a sequential mixed methods approach involving both a visitor survey and in‐depth interviews. The findings show the international city break trip to have a number of distinctive characteristics. These are summarised into five main areas (5 Ds) — duration, distance, date flexibility, discretionary nature and destination travel party. These distinguishing features provide a useful insight into one of the most important yet least examined travel segments in tourism research. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

'Expert Systems' or intelligent knowledge-based computer systems can be expected to have a considerable impact in the near future on the dissemination and use of technical expertise in practical situations. The potential benefits of such an approach to decision-making in applied science domains, for example, in anti-corrosive coating selection, are considerable. This paper argues, therefore, that a premium must be placed on such a system's performance as a communicator.
The structure and behaviour of a classical 'production system' are briefly described, and the communicative ability of such a system is analysed. This critical examination of a production system's question-answering capabilities highlights the inherent restrictions which the structure of this kind of system places on its explanatory and justificatory powers. An outline design for a less inhibitive structure is presented.
It is argued that the form in which the system provides 'answers' after the completion of a problem-solving session, may not yield sufficient appropriate information to the user, and a possible alternative view of a 'solution schema' is proposed.  相似文献

The Welsh Consumer Council launched its online interactive consumer network in July 2001 with the aim of linking up individual consumers across the country, stimulating discussion and debate on consumer issues and strengthening the voice of consumers in Wales. By October 2002, the network had recruited 300 members. The Council aims to reach a membership of 1000 by 2004. As well as individual consumers, the network has recruited 34 voluntary and community organisations that are committed to working with the Council to ensure that disadvantaged consumers without home Internet access can participate in the network At the heart of the network is a bilingual discussion area within the Council's one‐stop consumer information website where members can post their views, comments and observations on any consumer issue that concerns them. Over the past year, lively discussions have developed on subjects as diverse as IT and electronic communications, customer call centres, recycling, money‐making schemes and energy saving in the home. Early in 2002, the network began to run regular online surveys on topical consumer issues. The first survey asked about members’ experiences of returning goods and their knowledge of consumer rights. The second asked about members’ attitudes to recycling and reducing waste. Both surveys received a high level of response and provided valuable and up to date information on the experiences and views of consumers from all parts of Wales on these important issues. The continuing expansion of the consumer network is central to the Council work in helping to foster a consumer movement in Wales which is informed, responsible, demanding and assertive.  相似文献

Since sport is accorded such a significant position within national popular culture, it assumes corresponding importance in producing, reproducing and challenging racial myths. This paper explores how dominant notions of black physicality are embedded in sports practice and how such assumptions may be challenged. To do this we shall offer a critique of existing literature and, importantly, draw on empirical evidence from a recent study of the nature and extent of racism in rugby league. Together these allow us to explore tacit racism, that which is hidden and normalized by language and culture. At the heart of this are stereotypes of 'race' and racial qualities, created by white hegemonic culture with their significance perpetuated by society, including the people who experience the stereotyping. These cultural productions maintain inequalities even after the caricatures they portray may have changed. We examine how these historically specific images are formed and justified (and thereby normalized) and how they have material effects through the actions of coaches, managers, chairmen and players. Finally, we shall review how the sports arena can be used to challenge racist stereotypes to offer necessary, though not sufficient, conditions to begin to change social relations more generally.  相似文献

The increase in non-tariff barriers to trade in the industrial countries has given rise to much concern. This article attempts to summarize the formal non-tariff measures that have been introduced by the industrial countries to measure roughly how much trade is now affected by them.  相似文献
