CONTEXT Many persons who drink excessively remain unidentified and do not receive interventions. Screening and intervention using the World Wide Web could make such services more accessible and therefore more widely used. OBJECTIVE To evaluate the use of a novel alcohol screening and brief intervention Web site. DESIGN A Web site was developed, posted, and its use was evaluated. We analyzed...

A web site presents an intrinsic graph–like spatial structure defined by pages connected by hyperlinks. This structure may represent an environment on which agents related to visitors of the web site are positioned and moved in order to track their navigation. To consider this structure and to keep track of these movements allows to monitor the site and visitors, in order to support the enhance...

Recommender systems, in virtual museums and art galleries, providing the personalization and context awareness features require the off-line synthesis of visitors’ behaviors therein and the off-line training stage of those synthetic data. This paper deals with the simulation of four visitors’ styles, i.e., ant, fish, grasshopper, and butterfly, and the classification of those four styles using ...

Furthermore, the initial definition of a user model is also challenging since it should be built in a non-intru...

The purpose of this paper is to investigate the capabilities and limits of the passive mobile positioning (PMP) method in studying loyalty of tourists on the macro level. The repeat visitors were identified using database of call activities of roaming phones in Estonia since 25.04.2005 till 31.01.2009. For this purpose was developed model which selected repeat visits on the basis of time interv...

This paper reports the results of questionnaire–based research conducted at an exhibition of interactive humanoid robots that was held in the Osaka Science Museum, Japan. The aim of this exhibition was to investigate the feasibility of communication robots connected to a ubiquitous sensor network, under the assumption that these robots will be practically used in daily life in the not–so–distan...

In 1999, an outbreak of Legionnaires' disease affected many visitors to a flower show in the Netherlands. To identify the source of the outbreak, we performed an environmental investigation, as well as a case-control study among visitors and a serologic cohort study among exhibitors to measure exposure to possible sources. Of 77,061 visitors, 188 became ill (133 confirmed and 55 probable cases)...

Current policy is redirecting the emphasis and organisation of health visitor work, but guidelines state that health visitors and GPs ...
