The recent report by Barnhill and King about obesity prevention policy raises important issues for discussion and analysis. In response, this article raises four points for further consideration. First, a distinction between equality and justice needs to be made and consistently maintained. Second, different theories of justice highlight one additional important source of disagreement about the...

Throughout the present manuscript, we are going to introduce a novel group emergency decision-making technique in which the application of prospect theory explains the psychological behaviour of the decision maker who is affected by the hesitancy and uncertainty of cognition in decision making problems.\Instead of usual aggregation procedure, we implement here a new fusion technique that ...

Identity implications theory (IIT) is applied to analyze how young adults manage identity concerns associated with the goals of initiating, intensifying, and disengaging from romantic relationships. Participants wrote their responses to one of six hypothetical romantic (re)definition scenarios, indicated whether they actually would pursue the relational goal if their scenario were real, and rat...

In this paper we present a method for automatically extracting definitional contexts from restricted domains in Spanish. Definitional contexts are textual fragments where there is an implicit definition that can be identified by taking into account verbal patterns linking a term and its corresponding definition. Our interest is in definitional contexts with analytical definitions. Therefore, we...

We propose a new unidirectional proxy re-encryption scheme based on lattices. Our construction is collusion-safe and does not require any trusted authority for the re-encryption key generation. We extend a recent trapdoor definition for a lattice of Micciancio and Peikert. Our proxy re-encryption scheme is provably CCA-1 secure in the selective model under the standard assumption.
