Daniel Dennett’s Freedom Evolves is a rhetorically powerful but philosophically unconvincing attempt to show that a deterministic and ontologically reductionist, but epistemologically pluralist, outlook may peacefully coexist with a robust acceptance of human freedom and moral responsibility. The key to understanding the harmony rests in recognizing that freedom is not a metaphysical or physica...

As object-oriented approaches to software engineering are gaining wider acceptance, the body of software components available as reusable objects is expected to grow accordingly. The emerging object oriented database technology promises to provide appropriate access paths to such, possibly large and semantically rich, software bases [5]. The software engineer is then responsible for solving pro...

The set of points of a one-dimensional cut-and-project quasicrystal or model set, while not additive, is shown to be multiplicative for appropriate choices of acceptance windows. This leads to the definition of an associative additive graded composition law and permits the introduction of Lie algebras over such aperiodic point sets. These infinite dimensional Lie algebras are shown to be repres...

This paper discusses the early results of the multidisciplinary project TIVIPOL aiming to propose digital technologies to enhance the social life of older people in a retirement home. A prototype combining a tactile color screen, a RFID reader and a ticket printer is described. It allows the older people to manage their participation to the social activities organized by the home staff. A first...

The purpose of this article is to provide potential authors with a contemporary guide to scientific writing. It is in essence a handbook that covers the planning for a scientific publication from inception of the project or study to manuscript preparation and, ultimately, acceptance by a journal. Major topics such as manuscript formatting, data analysis, use of charts, graphs and images, refere...

We study the dynamic order acceptance and resource assignment problem of a service system which provides heterogeneous services using heterogeneous servers. Unlike traditional acceptance and/or assignment problems, decision makers in our settings can strategically postpone acceptance decisions anticipating more profitable orders to arrive, with the risk of lost orders and low resource utilizati...

In spite of their wide acceptance in other fields, phenomenological research methods have been greatly neglected by the IT community. In this paper, different validity threats that stem from the ontological and epistemological basis of this methodology are discussed and illustrated with a research project on IT-driven radical organizational change. In this way, it intends to provide practical g...

Design: We introduced a computer-based nursing documentation system on four wards of the University Hospitals of Heidelberg and systematically evaluated its preconditions and its effects in a pretest–posttest intervention study. For the analysis of user acceptance, we concentrated on subjective data drawn from questionnaires and interviews. Measurements: A questionnaire was developed using item...

Context: In medical and veterinary medical education the use of problem-based and cased-based learning has steadily increased over time. At veterinary faculties, this development has mainly been evident in the clinical phase of the veterinary education. Therefore, a consortium of teachers of biochemistry and physiology together with technical and didactical experts launched the EU-funded projec...

It is now over 10 years since the first publication on Critical Chain Project Management (CCPM) (Goldratt, 1997) and since then software and implementation practice has rapidly developed. The logic and assumptions underpinning this new knowledge has recently been published (Goldratt, 2007) in the form of a strategy and tactics (S&T) tree. It is, therefore, timely to review the CCPM claims from ...
