Information technology-based alliances are rapidly spreading in organizations, which calls upon researchers to develop an adequate theoretical lens to examine this phenomenon and its key associated outcomes, such as the business performance of alliance firms. However, strategic alliances are mostly examined from a transaction cost economics perspective, and the results on performance are inconc...

The transfer of organic material from one coastal environment to another can increase production in recipient habitats in a process known as spatial subsidy. Microorganisms drive the generation, transformation, and uptake of organic material in shallow coastal environments, but their significance in connecting coastal habitats through spatial subsidies has received limited attention. We address...

The specification of business processes is becoming a more and more critical aspect for organizations. Such processes are specified as workflow models expressing the logical precedence among the different business activities (i.e., the units of work). Up to now, workflow models have been commonly managed through specific subsystems, called workflow management systems. In this paper we advocate ...

It has become conventional to say that our knowledge of fundamental physical law is summarized in a Standard Model. But this convention lumps together two quite different conceptual structures, and leaves out another. I think it is more accurate and informative to say that our current, working description of fundamental physics is based on three standard conceptual systems. These systems are ve...

Model transformation is a key technology in modeldriven engineering. Unfortunately, transformations are typically written manually and thus they are likely to contain errors and to produce incorrect or undesired output. Safe transformation is the guarantee that for every possible source model, the transformed target model is valid with respect to user-definable wellformedness criteria. This pap...

The supersymmetric extension to the Standard Model offers a promising cold dark matter candidate, the lightest neutralino. I will review the phenomenological and cosmological constraints on the supersymmetric parameter space and discuss the prospects for the detection of this candidate in both accelerator and direct detection searches.

Though similarities between the Semantic Web language RDF(S) and languages of the Conceptual Graphs family have often been pointed out, the differences between these formalisms have been a source of difficulties while trying to translate objets of a language into the other. In this paper, we present two such transformations, that have been implemented into the CoGUI platform, and discuss their ...

1 Overview The goal of this demonstration is to present the main features of a Mediator component, Global Schema Builder, of an I3 system, called MOMIS (Mediator envirOnment for Multiple Information Sources) 1]. MOMIS 12 has been conceived to provide an integrated access to heterogeneous information stored in traditional databases (e.g., relational, object-oriented) or le systems, as well as in...

Collaborative Data Mining (CDM) develops techniques to solve complex problems of data analysis requiring sets of experts in different domains that may be geographically separate. An important issue in CDM is the sharing of experience among the different experts. In this paper we report on a framework that enables users with different expertise to perform data analysis activities and profit, in ...
