The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem.

This anthology of the very latest research on truth features the work of recognized luminaries in the field, put together following a rigorous refereeing process. Along with an introduction outlining the central issues in the field, it provides a unique and unrivaled view of contemporary work on the nature of truth, with papers selected from key conferences in 2011 such as Truth Be Told (Amsterdam), Truth at Work (Paris), Paradoxes of Truth and Denotation (Barcelona) and Axiomatic Theories of Truth (Oxford).

Con el libro "Poiesis Educativa", la Fundacion Universitaria de Derecho, Administracion y Politica, S.C. Editorial, da comienzo a la coleccion FUNDAp - Educacion, cuyo proposito fundamental es acoger las creaciones de los estudiosos de la educacion desde sus diversos campos y ambitos de desenvolvimiento. Es un libro que desde el titulo nos propone, nos inquieta, nos reta. La autora expone en el su preocupacion por el hecho de que la conceptualizacion actual de la educacion reduce y socaba a esta, en su empeno economicista y politicista de epistemologizar la educacion.

The present work considers the place of phenomenology within intercultural communication scholarship and argues for semiotic phenomenology as a theory and methodology that can address the current ‘paradigm crisis’ within the field. Current misunderstandings of phenomenology as an ‘interpretive’ research paradigm are challenged. ‘Metatheoretical’ efforts to develop dialectical approaches to the study of communication are critiqued for their failure to adequately interrogate the deep-seated cultural habits of perception that are necessarily present in intercultural communication research. Semiotic phenomenology is offered as a corrective that entails the capacity to address the question as to how we know when, in fact, we have truly achieved a shift at the habituated level of human experience where cultural perception is generated. Martin and Nakayama's (1999) dialectical perspective provides the context through which the discussion proceeds. A focus on Perice's categories of firstness, secondness, and thirdness constitute the theoretical point through which the argument proceeds.
