Stress and Schizophrenia: Some Definitional Issues

Definitional Issues in Functional Encryption

We provide a formalization of the emergent notion of “functional encryption,” as well as introduce various security notions for it, and study relations among the latter. In particular, we show that indistinguishability and semantic security based notions of security are inequivalent for functional encryption in general; in fact, “adaptive” indistinguishability does not even imply “non-adaptive”...

Innovation and Selection in Evolutionary Models of Technology: Some Definitional Issues

Atypical handedness in schizophrenia: some methodological and theoretical issues.

An updated review of the literature strongly supports the view that in schizophrenia there is an atypical leftward shift in the handedness distribution that, while comprising different subtypes, is characterized by a more variable and less completely lateralized pattern of manual preference, referred to as mixed handedness (MH) or ambiguous handedness (AH). Only two studies revealed an increase...

Definitional and Contextual Issues in Organizational and Group Memories

Organizations are looking to augment their memories through information technologies. Organizational and group memories can include a wide variety of materials, including documents, rationales for decisions, formal descriptions of procedures, and so on. This paper discusses findings from case studies of six organizations using or attempting to use the Answer Garden, a type of organizational mem...

On granular stress statistics: compactivity, angoricity, and some open issues.

We discuss the microstates of compressed granular matter in terms of two independent ensembles: one of volumes and another of boundary force moments. The former has been described in the literature and gives rise to the concept of compactivity: a scalar quantity that is the analogue of temperature in thermal systems. The latter ensemble gives rise to another analogue of the temperature: an ango...
