'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

Most existing literature focuses on the benefits of establishing basic drinking water access for unserved populations, the
extensive water supply margin. In contrast, this article examines the intensive margin—the benefits of improving water service
to under-served households, a growing population in developing country cities. We use contingent valuation to estimate willingness
to pay (WTP) for improved piped water quality and reductions in supply interruptions among a sample of 193 households in Lahore,
Pakistan. The distribution of WTP is described using parametric and non-parametric models. Results indicate that households
in Lahore are willing to pay about 7.50 to7.50 to 9 per month for piped water supply that is clean and drinkable directly from
the tap—comparable to the monthly cost of in-home water treatment, and about three to four times the average monthly water
bill for sample households using piped water. Estimates of WTP for reducing supply interruptions are both smaller and more
difficult to interpret, since a significant fraction of the estimated WTP distribution for supply improvements is negative.
All of our WTP estimates are well below 4% of monthly household income, the World Bank’s benchmark upper bound for affordable
water service. 相似文献

Professional accounting organizations and academicians in the United States have developed numerous frameworks and reports to address changes in the profession and to provide guidance for accounting educators in the implementation of curriculum change. In 1998, the American Institute of Certified Public Accountants (AICPA) released the Core Competency Framework for Entry into the Accounting Profession as an educational component of its CPA Vision Project. The online resource provides direct assistance to educators around the world in the implementation and assessment of the framework's recommendations. The purpose of this paper and the accompanying matrix, Comparison of US Accounting Education Frameworks with the Core Competencies, is to survey the history of contemporary American accounting education frameworks and compare earlier works with the most recent effort by the profession to recommend and institute accounting education change in the United States. 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 paper analyses the determinants and the evolution of income disparities across regions within Central and Eastern European Countries (CEECs) over 1991–2011. We add to the literature in different ways. First, we adapt the categories that Rodriguez‐Pose used for studying convergence among old EU members to CEECs regions. This allows us to assess the relevance of geo‐sectoral groups (urban areas, old industrialized areas and peripheral areas) for newcomer regions. Second, we introduce a new category, that of ‘successful Foreign Direct Investment (FDI)‐based restructuring’ in order to capture regions that, often through considerable FDI, manage to reconvert their old industrial base. We then analyze whether this group helps understand catching‐up/falling behind processes in CEECs. We test the relevance of these groups by means of both non‐parametric and spatial regression analyses. We find that they help explain the increase in within‐countries’ regional disparities especially after the turn of the century. 相似文献
