Embodied cognition is the hypothesis that behavior is not simply caused by the brain. Instead, behavior emerges from the interactions between brains in particular kinds of bodies embedded in environments that provide certain kinds of opportunities for activity. Theories of embodied cognition require a mechanism to support how these distributed resources can remain in contact with one another so...

Evolutionary branching occurs when frequency-dependent selection splits a phenotypically monomorphic population into two distinct phenotypic clusters. A prerequisite for evolutionary branching is that directional selection drives the population toward a fitness minimum in phenotype space. This article demonstrates that selection regimes leading to evolutionary branching readily arise from a wid...

In this paper logical techniques developed to formalise the analysis of multi-interpretable information, in particular belief set operators and selection operators, are applied to an ecological domain. A knowledge-based decision support system is described that determines the abiotic (chemical and physical) characteristics of a site on the basis of samples of plant species that are observed. Th...

Information systems nowadays are growing and changing with a high speed. The flourish of system applications and participators imply opportunities and enthusiasm. Knowledge of the systems’ evolution will be important to grasp the trend and so find a direction in the new era. To study the complicated and fast changing web environment, the article refers to ecological analysis. Two evolving model...

In the era of Web 2.0, the amount of information has been growing exponentially, intensifying the information overload problem.

Business analysts now need to explore an overwhelming amount of information in order to understand business ecosyst...
