A network of aligned ontologies is a distributed system, whose components are interacting and interoperating, the result of this interaction being, either the extension of local assertions, which are valid within each individual ontology, to global assertions holding between remote ontology syntactic entities through a network path, or to local assertions holding between local entities of an ontology, but induced by remote ontologies, through a cycle in the network. The mechanism for achieving this interaction is the composition of relations. In (...) this perspective, we introduce the notions of local composable relations, which relate ontology entities belonging to the same ontology, remotely induced composable relations, which relate ontology entities belonging to remote ontologies through a path of ontologies and alignments in the network, and network induced local composable relations, which relate ontology entities belonging to the same ontology, but through a path of ontologies and alignments forming a cycle starting and ending at the same ontology, to characterize the logical consequences extracted from a network of aligned ontologies, and we propose a category-based methodology for detecting semantic inconsistencies in networks of aligned ontologies, which is based on contravariant representable functors and on the definition of two composition operators suitable for propagating local knowledge through the network.

This article discusses the relationship between the post-2008 global economic crisis and trauma journalism through a quantitative study of reporters covering austerity’s everyday manifestations and examines the effects on the media professionals involved. The findings indicate that journalists who cover economic crisis-related incidents suffer specific symptoms of trauma. As such, the study re-conceptualizes the economic crisis as primarily affective for media workers, it establishes a direct correlation between the economic crisis and emotional trauma, and provides an insight into the kind (...) of trauma that stems from covering austerity and its impact on society. A regression analysis of symptoms indicates trauma journalism as an emerging field of research into the economic crisis. (shrink)
