The need for thesauri to help users in their search for information in online information systems has been discussed for several decades. Many wide‐ranging contributions have been made to solve this problem. Nevertheless, investigation is needed to design a thesaurus structure based on what is relevant for users and generators of information within a specific subject domain. This paper explores the possibility of creating a thesaurus from the cognitive viewpoint. This approach is based on a system (in this case represented by a thesaurus) that organises its representation of knowledge or its classification as closely as possible to the authors‘ and users’ images of the subject domain with the objective of increasing the interaction between users and texts, and thus the communication in a given information retrieval system. From this point of view, the thesaurus structure is considered as the essential foundation on which to base such an interactive thesaurus. Furthermore, this structure is conceived as representing the merging point for both the generators‘ and the users’ models of the subject domain and for their information needs. This paper is dedicated mainly to the generators‘ side involved in this process. It demonstrates how an author’s writings can be used to identify the generators‘ model and perception of the subject domain, and how these can later be inserted in the thesaurus structure. Discourse analysis is used as a main method to identify the categories and its relevance for building such a structure is discussed. It also outlines a general approach for the user side to set up different methods of getting the users’ information needs into the thesaurus structure.

Presents results of data obtained regarding faculty attitudes concerning the ethical propriety of and estimated faculty involvement with 38 activities. A questionnaire was sent to 480 randomly selected information systems (IS) academicians. Insights into the ethical standards of IS faculty are provided by the data, as well as the indication that a significant minority of faculty are estimated to be involved in most activities contrary to normative standards of ethical conduct, as prescribed by peers. Also identifies several attitudinal differences, based on demographic characteristics of respondents and institutions.

The Geography of Tourism in Spain is now at a par in terms of its scientific production with other European countries. Since the middle of the '80s the quality and volume of contributions is analogous to the rest of the European Union, although as a part of University Geography in Spain it has not achieved the level of dedication reached by other subjects considering the importance of tourist activities to the economy, the society and the territory of Spain. It could be said that the Geography of Tourism in Spain is in the international vanguard in dealing with Mediterranean coastal tourism, with the relationships between the residential real estate and tourism sectors and with aspects related to tourism and leisure in rural and protected areas.

This article, third in a series of six, describes Life Sciences Era activities. Life sciences, rapidly gaining momentum, will begin to dominate US economic activity by 2100, then predominate well into the following century (see Figure 1). Massive advances will follow as the 140 000 genes, and 3 billion molecular units (base pairs) comprising the human genome are plotted in rough draft before 2001, and definitively charted by 2003. Once laid out, comprehending genetic patterns provides the means to govern many of the 75 trillion parts in every human.

The aim of this work was to validate the Wilson and Laing theoretical mathematical model for estimating the intrinsic “dry” thermal resistance of upper‐bedding, and compare the two‐dimensional models commonly used to estimate the “dry” thermal resistance of bedding in use, with the actual intrinsic “dry” thermal resistance measured using an infant thermal manikin. The Wilson and Laing model was the only model used adequately to estimate the intrinsic “dry” thermal used resistance of materials arranged over the infant thermal manikin. Estimation of intrinsic “dry” thermal resistance of bedding during use is not adequate using two‐dimensional models. Further investigation into the relationship between thermal resistance, conditions of use, and SIDS using the Wilson and Laing model is recommended.

Introduction Le tourisme qui fut d'abord le privilège de la classe riche au cours du XIXe siècle et qui se limita à la pratique de l'alpinisme, aux longs séjours d'été dans quelques stations thermales, lacustres, balnéaires ou montagnardes, aux séjours d'hiver sous les climats plus doux des bords de la Méditerranée, devint un phénomène de masse à partir de la deuxième guerre mondiale. La clientèle, les types de tourisme, les moyens de transports, les régions fréquentées se sont diversifiés et ont augmenté à un tel rythme et avec une telle ampleur que de nouvelles et nombreuses professions sont apparues.

This communication describes the building of a list of constructed impact factors (CIF) for biomedical journals not included in the 1996 editions of the Journal Citation Reports (JCR). The online retrieval from the host DIMDI of the data needed for impact factor calculation is described in detail. At present, the CIF list comprises 338 titles. The top 100 (ranked according to their CIFs) are shown. The complete list is available via the World Wide Web at the URL: http://www.medizin.fu‐berlin.de/medbib/CIF/cif.html. The possible usefulness of constructed impact factors for citation and evaluation studies is discussed.
