This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a mea...

INTRODUCTION Existing definitions of women's sexual disorders are based mainly on genitally focused events in a linear sequence model (desire, arousal and orgasm). AIM To revise definitions based on an alternative model reflecting women's reasons/incentives for sexual activity beyond any initial awareness of sexual desire. METHODS An International Definitions Committee of 13 experts from se...

EcoLexicon (http://ecolexicon.ugr.es) is a terminological knowledge base on the environment that currently holds 3,351 concepts and a total of 17,475 terms in English, Spanish, German, Russian, French, and Modern Greek. Concepts are linked by means of hierarchical and non-hierarchical relations in dynamic networks and in definitions. The environmental domain is interdisciplinary and its concept...

This paper is a contribution to the formal study and analysis of vernacular forms of program derivation. Specifically, in this paper, our vernacular derivations are elementary program transformations over the natural numbers. We provide an intensional semantics for these transformations within the derivations of the Elementary theory of Operations and Numbers, EON, [Bee85]. This semantics is in...

This paper presents a new metamodel based on partially ordered hypersets. The metamodel is minimalist, its only primitives being atoms, potentially infinite hypersets and partial order. The type system is very loose and supports concurrent extensional and intensional definition of types. Every element of the metamodel can be directly referenced, thanks to a powerful automated reification facili...

Sedentary behavior is a modifiable determinant of health. Little is known about the ways in which contextual factors may influence this behavior. The objectives of this study were to: (1) examine the association between community belonging and adult sedentary behavior during leisure; (2) determine if this association was explained by perceived health. Data were derived from the 2010 Canadian Co...

Designing programmable privacy logic frameworks that correspond to social, ethical, and legal norms has been a fundamentally hard problem. Contextual integrity (CI) (Nissenbaum 2010) offers a model for conceptualizing privacy that is able to bridge technical design with ethical, legal, and policy approaches. While CI is capable of capturing the various components of contextual privacy in theory...
