The mStar environment for distributed education utilizes the WWW and IP-multicast to enable teacher-student collaboration over large geographic distances. Several educational projects, spanning from secondary school courses to in-house training in companies, have deployed the mStar environment. This paper reports on experiences gained over a year of practice at Luleå University of Technology an...

This paper presents a framework for analysing the role of regional headquarters in the globalisation strategies of transnational corporations (TNCs). Drawing upon a theoretical gap in existing urban studies and international business literature, we argue that the triadisation and regionalisation of TNC activities increase the demand for control and co-ordination functions previously performed b...

As Global Virtual Teams (GVTs) operate across diverse geographies, time-zones, and cultures, they present particular problems for project management in that their characteristics may negatively affect team performance. While a significant body of research exists on project management and GVTs, previous studies have not fully elaborated on the collective impact that GVT characteristics, such as ...

efforts on both sides. The European part is based on the SIMDAT project (Data Grids for Process and Product Development using Numerical Simulation and Knowledge Discovery), which joins forces for product development and production process design using Grid services. CN Grid, a similar project with comparable objectives, was launched in China in 2002. While SIMDAT uses GRIA (GRID Resources for I...

Existing studies have often failed to find positive impacts of horizontal FDI on domestic firms. We argue that the two effects underpinning the impacts of horizontal FDI (i.e., the positive spillover effect and the negative competition effect) have different degrees of attenuation with geographic distance. As FDI is often distributed unevenly across space, studies that do not account for the ge...

We numerically investigate the epidemic spread phenomena and efficient immunization strategies on complex networks embedded in geometry. It is assumed that there exists an unavoidable time delay (we call it the detection time) between the actual infection and the beginning of immunization, and we implement two different immunization strategies: one is based on topological connection neighbors (...

The value of using otolith chemistry to characterize recruitment in terms of natal source regions depends on how consistently spatio-temporal variation can be resolved. The objective of this study was to compare regional classification patterns in the otolith chemistry of juvenile Spotted Seatrout (Cynoscion nebulosus) between two years experiencing disparate hydrological regimes, and separated...

The paper analysis the role of the Internet for different types of innovation not only focusing on the traditional set of product, process, organizational and marketing innovation, but also extending to innovation in the public sector. In addition to the role of the Internet for various types of innovations, it has also implications for new forms of innovation, especially for the new paradigm o...

Résumé. L’image médicale 4D représente une succession d’images volumiques sur l’axe temporelle, ce qui représente une énorme quantité de données à compresser afin de la stockée ou de la transmettre. Dans cet article, nous présentons une technique de compression d’images médicales 4D basée sur le SPIHT3D. Cette technique applique la transformée en ondelettes 3D afin d’éliminer efficacement les r...

In the 1970s, some people believed in using computers for making almost any information available to anyone and for supporting information exchange and discussions regardless of geographical distances. These ideas were, at that time, novel and revolutionary. Some people regarded these ideas as dangerous; for example, the Swedish Data Inspection Board (Datainspektionen) forbade people from stori...
