In 2003, the city of Vancouver, British Columbia, opened North America's first government-sanctioned safer injecting facility, where injection drug users (IDUs) can inject preobtained illicit drugs under the supervision of nurses. Use of the service by IDUs was followed by measurable reductions in public drug use and syringe sharing. IDUs who are frequently using the program tend to be high-int...

BACKGROUND Despite Thailand's official reclassification of drug users as "patients" deserving care and not "criminals," the Thai government has continued to rely heavily on punitive responses to drug use such as "boot camp"-style compulsory "treatment" centers. There is very little research on experiences with compulsory treatment centers among people who use drugs. The work reported here is a ...

BACKGROUND Older HIV patients are defined as aged 50 years and older. This group is a growing population in developed countries. In order to improve care for older HIV patients, we intended to gain insight into the specific features of transmission, epidemiology, immunology and antiretroviral treatment (ART) of this population. PATIENTS AND METHODS All patients from the RESINA cohort were ana...

We are developing an Intelligent Network News Reader which extracts news articles for users. In contrast to ordinary information retrieval and abstract generation, this method utilizes an "informa-tion context" to select articles from newsgroups on the Internet and it displays the context visually. A salient feature of this system is that it retrieves articles dynamically, adapting itself to th...

We describe an interaction console for interactive proof exercises using proof planning as back-engine. Based on the proof planning situation, the console offers suggestions for proof steps. These suggestions can dynamically be adapted, e.g. to the user and to pedagogical criteria. This adaptive configuration is possible because the suggestion mechanism and proof planning are clearly separated....

BACKGROUND The advent of combinatorial chemistry has revived the interest in five-membered heterocyclic rings as scaffolds in pharmaceutical research. They are also the target of modifications in nucleic acid chemistry. Hence, the characterization of their conformational features is of considerable interest. This can be accomplished from the analysis of the 3J(HH) scalar coupling constants. R...

In this paper we describe the design and implementation of an adaptive multimodal fission component integrated in the multimodal GUIDE framework. This component is able to adapt any TV based application’s UI to a specific user’s characteristics making possible for elderly and impaired users to interact by offering several output modalities that tries to overcome his difficulties of interaction.

This position paper is an interpretation of the special theme of the 3rd EuroITV conference (2005): “User centred systems, programmes and applications.” It investigates the question: How does the generic notion of “user centric” translate into specific actions for interactive TV user interface design and evaluation? Traditional usability engineering techniques have been popular, but it is argue...

This article emphasizes the significance of the user interface design to the development of an accurate mental or conceptual model by the users of a hypermedia computer system. It begins with a review of the role of mental/conceptual models and their importance to hypermedia users. Also discussed are the role of the user interface in hypermedia systems and specific design issues that impact the...
