When data is maintained over geographically distributed sites the computational power of distributed and parallel systems can be exploited for knowledge discovery in scientific data. In this scenario the Grid can provide an effective computational support for distributed knowledge discovery on large datasets. In particular, Grid services for data integration and analysis can represent a primary...

in the business environment, virtual organizations can meet market needs efficiently and effectively via knowledge worker and high flexibility and also generate significant competitive advantage. due to obtaining the advantage of these organizations, managerial issues related to them must be recognized and organized. decrease of face to face relationship, geographically distributed, dynamic job...

BACKGROUND: Limited information is available about teenage pregnancy and childbearing in rural areas, even though approximately 20 percent of the nation's youth live in rural areas. Identifying whether there are differences in the teenage birth rate (TBR) across metropolitan and nonmetropolitan areas is important, because these differences may reflect modifiable ecological-level influences such...

Contemporary organizations and communities make increasing use of advanced information system and communication technologies to collaborate and interact with each other in geographically and temporally distributed settings. In broad terms, these are referred to as virtual environments. Examples of such virtual environments include virtual work (encompassing telework and distributed work), virtu...

In recent years, an increasing number of companies and organizations have put in place geographically distributed teams to carry out development of various products – in particular software products. This trend has economic drivers (globalization, outsourcing) and has been facilitated by the IT revolution (better, cheaper communications). However, it has brought new challenges for the organizat...

INTRODUCTION With the advent of Gbps-range Research and Engineering networks, traditional video conferencing has been evolved toward advanced collaboration environments (ACE). The ACE enables users to share an ensemble of resources multimedia, documents, and applications. The ACE has been widely used for seamless cooperative works among users at geographically distributed sites such as large-sc...

The Healthcare Administrator's Associate is a collection of portable tools designed to support analysis of data retrieved via the Internet from diverse distributed healthcare information systems by means of the InfoSleuth system of distributed software agents. Development of these tools is part of an effort to enhance access to diverse and geographically distributed healthcare data in order to ...

Distributed software development presents several characteristics that differentiate from co-located software development. Currently, one of the main difficulties imposed by geographically distributed software teams is the requirements engineering process. Traditional approaches to requirements process don’t cover the fundamental difficulties of dispersion, like communication and coordination. ...
