In this article a set of requirements for the design of a personal document management system is presented, based on the results of three research studies (Bondarenko, 2006; Bondarenko & Janssen, 2005; Bondarenko & Janssen, 2009). We propose a framework, based on layers of task decomposition, that helps to understand the needs of information workers with regard to personal document and task management. Relevant user processes are described and requirements for a document-management system are derived for each layer. The derived requirements are compared to related studies, and implications for system design are discussed. © 2009 ASIS&T.

In current business practice, an integrated approach to business and IT is indispensable. In many enterprises, however, such an integrated view of the entire enterprise is still far from reality. To deal with these challenges, an integrated view of the enterprise is needed, enabling impact/change analysis covering all relevant aspects. This need sparked the development of the ArchiMate language, which was developed with the explicit intention of becoming an open standard, and as such has been designed such that it is extendable while still maintaining a clear and orthogonal structure. This article is concerned with documenting some of the key structures and design principles underlying the ArchiMate language. ArchiMate is designed as an architecture description language (ADL) for enterprise architectures. The authors will start by discussing the challenges facing the design of an architecture description language. Consequently we discuss how the design principles of the ArchiMate language aim to tackle these challenges. They then continue with a discussion of the modelling concepts needed. In this, we make a distinction between concepts needed to model domains in general, the modelling of dynamic systems, and the modelling of enterprise architectures. Copyright © 2010, IGI Global.

In this project people with dementia and their carers were asked to describe their problems in daily life. With their input integrated solutions for people with dementia were developed. The aim was to develop solutions that help ageing people with early dementia to experience greater autonomy and feelings of empowerment, and to enjoy an enhanced quality of life. This movie shows the solutions that were developed during the project. © 2010 Copyright is held by the author/owner(s).

Background: A locum practitioner is an out-of-hours general practitioner who needs access to the electronic health record of visiting patients. The electronic locum record is a summary of the electronic health record available to the locum practitioner and includes the most significant health problems, the most recent records of the patient's visits to the practice, current medication data and information on allergies and intolerances. The locum practitioner returns a locum medical note to the electronic health record at the general practitioner with his or her diagnosis, treatment or referral of the visiting patient. A pilot project of the electronic locum record was implemented in the Twente region of the Netherlands. Objective: To obtain policy information for the nationwide implementation of the electronic locum record as a first component of the electronic health record in the Netherlands. Methods: First, evaluation aspects were collected from parties involved in the pilot implementation process. Aspects were taken from the work flow to operationalise the electronic health record. Secondly, indicator questions were formulated and normative levels agreed for each indicator by a panel with experts from the medical and information technology domain. Third, the actual values were rated either by measurement (technical indicators) or by structured interviews (process indicators) with the general practitioners who joined the pilot study. Finally, a cross case analysis was performed by checking for (in-)consistencies among the respondents. Results: Eight out of the 15 key indicators scored positive, three failed and four remained inconclusive. The indicators that failed the norms related to the guideline for electronic registration of patient information, the process of acquiring the healthcare professional identification card and card-related services. Indicators that remained inconclusive referred to storing and archiving of identification cards and codes, the use of the identification repository at the general practice post and the usefulness and ease-of-use of the electronic locum record. Conclusions: The study demonstrates that many processes, systems, services and practices for nation-wide implementation of the electronic locum record for general practitioners in the Netherlands are in place. However, significant improvements are required on a number of aspects. For example general practitioners need to be trained more in applying the guideline for electronic registration of patient data. Also the process for general practitioners to acquire their unique healthcare professional identification cards should require less effort. We also recommend that a strong regional information technology support group should be in operation during roll-out. © 2010.

In many cases keywords from a restricted set of possible keywords have to be assigned to texts. A common way to find the best keywords is to rank terms occurring in the text according to their tf.idf value. This requires a corpus of texts from which document frequencies can be derived. In this paper we show that we can obtain results of the same quality without the usage of a background corpus, using relations between terms provided in a thesaurus. © 2010 IEEE.
