We argue, in light of Collapse Model interpretation of quantum theory, that the fundamental division between the quantum and classical behaviors might be analogous to the division of thermodynamic phases. A specific relationship between the collapse parameter $$(\lambda )$$ and the collapse length scale ( $$r_C$$ ) plays the role of the coexistence curve in usual thermodynamic phase diagrams. We further claim that our functional relationship between $$\lambda$$ and $$r_C$$ is strongly supported by the existing International Germanium Experiment (IGEX) collaboration (...) data. This result is preceded by a brief discussion of quantum measurement theory and the Ghirardi–Rimini–Weber (GRW) model applied to the free wavepacket dynamics. (shrink)

Se realizó un estudio de intervención con el objetivo de elaborar una estrategia educativa para incrementar conocimientos sobre sexualidad sana en un grupo de adolescentes de la escuela Secundaria Básica Alfredo Gómez del Municipio Camagüey entre octubre de 2012 y febrero de 2013. La muestra fue de 37 estudiantes. Se aplicó una encuesta que se convirtió en el registro primario de datos, confeccionada según criterios de expertos y la bibliografía. Una vez analizados los resultados se procedió a diseñar la (...) estrategia educativa y posteriormente a su evaluación. Los datos se procesaron de forma automatizada. Antes de aplicar la estrategia educativa se comprobó que los adolescentes no tenían un adecuado conocimiento sobre la sexualidad sana. Los resultados demuestran la importancia de los estudios de intervención. An interventional study was developed with the objective of designing an educational strategy to increase the knowledge about healthy sexuality in a group of teenagers from Alfredo Gómez Secondary School in Camagüey municipality between October 2012 and February 2013. The sample included 37 students. The applied survey became the primary data register. It was designed according to the experts´ criteria and the bibliography. Once the results were analyzed the educative strategy was designed and evaluated. The data was computerized. Before applying the educative strategy it was evident that the students did not have an appropriate knowledge about healthy sexuality. The results show the importance of interventional studies.

Trecho da obra: "Nos itinerários históricos mais recentes, o corpo atlético, de alto rendimento, tornou-se metáfora da superação de si e lugar de sacralização de quase ilimitados recursos tecnocientíficos. (...) O desempenho dos corpos no campo desportivo pode ser compreendido como concretização daquela mitologia do progresso que moldou a experiência do tempo na modernidade. (...) Os trânsitos entre desporto, ética e transcendência foram o objecto de estudo e reflexão de um colóquio internacional realizado na Universidade Católica Portuguesa, e o presente (...) volume, dando continuidade a uma política de publicação do Instituto Português do Desporto e Juventude / Plano Nacional de Ética no Desporto, reúne os textos apresentados, procurando, assim, atingir um público mais amplo e contribuir para o aprofundamento desta linha de indagação na sociedade portuguesa.".

Es esencial fortalecer el camino hacia la mayor participación y la expansión democrática; sin embargo, aún se sigue considerando al género como un marcador de diferencia. Con un estudio de multicasos, transversal con enfoque metodológico mixto, se concluyó que los directivos tienden a estereotipar su propio comportamiento de acuerdo a los valores culturales concebidos por la sociedad para cada sexo y que el mayor desarrollo de la práctica de la dirección, principios de dirección masculina según Mintzberg y/o femenina según Helgesen (...) con la finalidad de plantear lineamientos de mejora, se puede deber al énfasis que ponga cada director o directora.

Clinician gate-keeping is the process whereby healthcare providers prevent access to eligible patients for research recruitment. This paper contends that clinician gate-keeping violates three principles that underpin international ethical guidelines: respect for persons or autonomy; beneficence or a favourable balance of risks and potential benefits; and justice or a fair distribution of the benefits and burdens of research. In order to stimulate further research and debate, three possible strategies are also presented to eliminate gate-keeping: partnership with professional researchers; collaborative research (...) design and clinician education.

Este artículo analiza la incorporación del soft power como elemento de la política exterior de China para América Latina. Sostenemos que China cuenta con soft power y ha desarrollado una estrategia para proyectarlo en el mundo a partir de su política exterior, basándose en su cultura milenaria, en la cooperación internacional hacia los países en desarrollo y en la promoción de su modelo de desarrollo. Asimismo, la inclusión de China del soft power como elemento de su política exterior en la (...) primera mitad de la década de 2000 tendrá efectos medibles en la intensificación de las relaciones con América Latina en la segunda mitad de esa década.

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same (...) theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative. (shrink)

LA JUVENTUD CONSUMIDA: REPRESENTACIONES DE LO JUVENIL EN EL DISCURSO PUBLICITARIO.

The Critique of Pure Reason—Kant’s First Critique—is one of the most studied texts in intellectual history, but as Alfredo Ferrarin points out in this radically original book, most of that study has focused only on very select parts. Likewise, Kant’s oeuvre as a whole has been compartmentalized, the three Critiques held in rigid isolation from one another. Working against the standard reading of Kant that such compartmentalization has produced, The Powers of Pure Reason explores forgotten parts of the First (...) Critique in order to find an exciting, new, and ultimately central set of concerns by which to read all of Kant’s works. Ferrarin blows the dust off of two egregiously overlooked sections of the First Critique—the Transcendental Dialectic and the Doctrine of Method. There he discovers what he argues is the Critique’s greatest achievement: a conception of the unity of reason and an exploration of the powers it has to reach beyond itself and legislate over the world. With this in mind, Ferrarin dismantles the common vision of Kant as a philosopher writing separately on epistemology, ethics, and aesthetics and natural teleology, showing that the three Critiques are united by this underlying theme: the autonomy and teleology of reason, its power and ends. The result is a refreshing new view of Kant, and of reason itself. (shrink)

El artículo parte de la preocupación de saber cómo se está desarrollando la formación de investigadores en las universidades brasileñas. Una primera dificultad que se coloca es el predominio de un abordaje segmentado de la investigación científica. Eso lleva a un cuestionamiento sobre si particularmente las asignaturas de metodologías sirven para formar investigadores. Entre diversas dificultades, se incluyen desde aspectos epistemológicos hasta los impactos de las asignaturas metodológicas sobre la formación de los investigadores. Se cuestionan las estructuras de las disciplinas, (...) su relación con las metodologías, y las relaciones entre enseñanza metodológica y prácticas de investigación. Lo que está en juego es la formación de científicos sociales críticos en que se cuestionen diferentes separaciones extremamente rígidas de los procesos de formación.The present article focuses on the concern to know how the process of preparing investigators at Brazilian universities is being developed. One of the first difficulties being dealt with involves the predominant of segmented approach of the scientific investigation. This leads to the questioning of methodologies used to prepare these investigators. Among other several difficulties, the epistemological aspects up to the methodological ideas on the preparation of investigators are included. The structures of the subjects, their relation to the methodologies and the relations between methodological teaching and investigation practices are questioned. The preparation of critical social scientists in which extremely rigid different separations from the preparation processes is at stake here. (shrink)

In previous works, we presented a modification of the usual possible world semantics by introducing an independent temporal structure in each world and using accessibility functions to represent the relation among them. Different properties ofthe accessibility functions have been considered and axiomatic systems which define these properties have been given. Only a few ofthese systems have been proved tobe complete. The aim ofthis paper is to make a progress in the study ofcompleteness for functional systems. For this end, we use (...) indexes as names for temporal flows and give new proofs of completeness. Specifically, we focus our attention on the system which defines injectivity, because the system which defines this property without using indexes was proved to be incomplete in previous works. The only system considered which remains incomplete is the one which defines surjectivity, even ifwe consider a sequence ofnatural extensions ofthe previous one. (shrink)

Argument evaluation, one of the central problems in argumentation theory, consists in studying what makes an argument a good one. This paper proposes a formal approach to argument evaluation from the perspective of justification logic. We adopt a multi-agent setting, accepting the intuitive idea that arguments are always evaluated by someone. Two general restrictions are imposed on our analysis: non-deductive arguments are left out and the goal of argument evaluation is fixed: supporting a given proposition. Methodologically, our approach uses several (...) existing tools borrowed from justification logic, awareness logic, doxastic logic and logics for belief dependence. We start by introducing a basic logic for argument evaluation, where a list of argumentative and doxastic notions can be expressed. Later on, we discuss how to capture the mentioned form of argument evaluation by defining a preference operator in the object language. The intuitive picture behind this definition is that, when assessing a couple of arguments, the agent puts them to a test consisting of several criteria. As a result of this process, a preference relation among the evaluated arguments is established by the agent. After showing that this operator suffers a special form of logical omniscience, called preferential omniscience, we discuss how to define an explicit version of it, more suitable to deal with non-ideal agents. The present work exploits the formal notion of awareness in order to model several informal phenomena: awareness of sentences, availability of arguments and communication between agents and external sources. We discuss several extensions of the basic logic and offer completeness and decidability results for all of them. (shrink)

In this paper, we focus on a logical approach to the important notion of closeness, which has not received much attention in the literature. Our notion of closeness is based on the so-called proximity intervals, which will be used to decide the elements that are close to each other. Some of the intuitions of this definition are explained on the basis of examples. We prove the decidability of the recently introduced multimodal logic for closeness and, then, we show some capabilities (...) of the logic with respect to expressivity in order to denote particular positions of the proximity intervals.

ABSTRACT In this paper we present a new semantic approach for propositional linear temporal logic with discrete time, strongly based in the well-order of IN (the set of natural numbers). We consider temporal connectives which express precedence, posteriority and simultaneity, and they provide a family of expressively complete temporal logics. The selection of the new semantics and connectives used in this work was principally to obtain a suitable executable temporal logic, which can be used for the specification and control of (...) process behaviour in discrete time in a similar way to thai presented by D. Gabbay in [GAB 89], Our new approach has two advantages: firstly, the connectives are defined intuitively so that they have interpretations which relate to properties of interest in real systems; secondly, it provides a new semantics that facilitates simpler proofs of many valid formulas and metatheorems. To confirm this second advantage, we use our semantics to give a formal proof of the Separation Theorem for one of these logics (specifically LN3). The great interest of this Separation Theorem for the executable temporal logic is emphasised by D. Gabbay in [GAB 89], [GAB 88]. (shrink)

Combining modalities has proven to have interesting applications and many approaches that combine time with other types of modalities have been developed. One of these approaches uses accessibility functions between flows of time to study the basic properties of the functions, such as being total or partial, injective, surjective, etc. The completeness of certain systems expressing many of these properties, with the exception of surjectivity, has been proven. In this paper we propose a language with nominals to denote the initial (...) and final sets of each function in a model in order to obtain a complete system for reasoning about surjective partial functions.
