Electronic document delivery is a concept which promises to solve end‐user problems in retrieving the primary information referenced to in bibliographical databases. This article describes an approach to electronic document delivery which gradually evolved at Tilburg University over the past two years, leading to the development of a system called Ariadne. First of all, a pragmatic description of electronic document delivery is developed as a basis for a generation model of electronic document delivery systems. This model is illustrated with short references to existing systems and leads to the identification of global requirements for an Ariadne‐like system. Special attention will be paid to existing and developing standards in this field, notably the work of the Group on Electronic Document Interchange (GEDI). The remainder of the article addresses the general model of Ariadne, currently under development at Tilburg University. The article concludes with some strategic issues for libraries and publishers in this field, and a short look into the future.

This paper examines the general value to users of a range of electronic journal functions and their usefulness in the specific context of the SuperJournal Project. For the evaluation of each of the functions three types of data were analysed in relation to each other and in light of other contextual data: logged data of usage, survey data on user satisfaction, and survey data on the perceived importance of the function. The analysis shows that basic browsing, printing and search make up the core functions of electronic journals; other functions, such as saving of bibliographic data, alerting, customising, links with external resources and communication, serve as peripheral functions. The usefulness of both the core functions and the peripheral functions in a specific service is influenced by various implementation factors. However, it is the realised usefulness of the core functions which determines the use of a service.

The purpose of this paper is to apply negative thermal coefficient (NTC) thick film segmented thermistors (TFSTs) in a micro‐flow sensor for water.

A TFST is printed using NTC paste based on nickel manganite. The resistance of this thermistor is measured in a climatic chamber and the resulting curves are calibrated. A micro‐flow sensor is designed using a self‐heated segmented thermistor. The sensing principle is based on heat loss depending on the water flow intensity through the capillary. Water flow calibration is performed. The sensor sensitivity, inertia, and stability are analyzed.

The micro‐flow sensor exhibits good stability, suitable sensitivity, and inertia for integral measurements of water flow.

Advantages of a micro‐flow sensor using a TFST include low energy consumption, simple measuring procedure, and passive electronics.

This paper describes initial work on a micro‐flow sensor for water using TFSTs.

The purpose of this paper is to focus on ethical and judicial themes related to technology and the older adults.

Different consecutive phases in technology design and allocation will be discussed from a range of perspectives.

Longevity is one of the greatest achievements of contemporary science and a result of development of social relations. Currently, various non-communicable diseases affect older adults and impose the greatest burden on global health. There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for good quality of life (QOL). The concept of assisting the older adult through the use of technology so as to access healthcare services has enormous potential. Although the potential of technology in healthcare is widely recognised, technology use can have its downsides. Professionals need to be aware of the risks, namely, those related to the privacy of the older person, which may accompany technology use.

By 2050, there will be more people aged over 65 than there are children. This phenomenon of global ageing constitutes a massive challenge in the area of health protection.

Professionals need to be aware of the risks, for example, related to the privacy of the older person, that may accompany technology use.

There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for QOL.

The concept of assisting the older adult through the use of technology to avail of healthcare has enormous potential. Assistive technology, social media use and augmentative and alternative communication can have a positive effect on the QOL of older people, as long as they are supported enough in use of these technologies. However, ethical and juridical considerations are at stake as well.
