Agile software development represents a major approach that has gained increasing popularity in recent years. Economy forces agile organizations to overcome geographical distances to benefit from accessing a larger resource pool and to reduce development costs. However, agile and distributed development approaches differ significantly in their key tenets. While agile methods mainly rely on info...

The idea of the creative individualist spawning innovations as a solitude effort is no longer realistic. Huge innovation projects, relying on project teams, have to be permanently conducted by organizations to assure their competitiveness. These projects often take place in distributed teams, making use of groupware to bridge temporal and geographical distances. Research in social psychology on...

This paper explores the management of expertise in offshore outsourcing projects. While the study of expertise development and coordination gained some attention in recent years, much of this research has been on co-located teams. Little is known about the way expertise is managed in distributed contexts and the challenges distributed teams face when attempting to develop and share expertise. T...

Huge amounts of network traces can be collected from today’s busy computer networks. Analyzing these traces could pave the way to detect unusual conditions and/or other anomalies. Presently, due to the lack of effective substantiating mechanisms intrusion detection systems often exhibit numerous false positives or negatives. The efficiency of a network intrusion detection system (NIDS) depends ...

Currency crises appear to spread regionally. In this paper we use Bayesian methodology on data from four waves of currency crises in the late twentieth century to examine the mechanism by which currency crises spread from one country to another. In particular, we examine whether trade linkages, “other” unquantifiable linkages proxied for by relative geographical distance, or macroeconomic and f...

Climate extremes are expected to become more frequent and intense under future warming. In a globalized economy, outages of productive capital and infrastructure have the potential to spread around the world. In order to address those repercussions in the framework of a risk analysis or a resilience strategy, a disaster’s indirect consequences on the economic supply network need to be understoo...

This work presents a generic programming interface, or API (Application Programming Interface), for spatial operations in geographical database developed in the TerraLib environment a base library for construction of geographical applications with integrated architecture. This API provides operations on geographical data stored in relational DBMS (RDBMS) and object-relational DBMS (ORDBMS). In ...

Metadata is the important information describing geographical data resources and their key elements. It is used to guarantee the availability and accessibility of the data. ISO 19115 is a metadata standard for geographical information, making the geographical metadata shareable, retrievable, and understandable at the global level. In order to cope with the massive, high-dimensional and high-div...
