The beliefs of the agents in a multi-agent system have been formally modelled in the last decades using doxastic logics. The possible worlds model and its associated Kripke semantics provide an intuitive semantics for these logics, but they commit us to model agents that are logically omniscient. We propose a way of avoiding this problem, using a new kind of entities called subjective situations. We define a new doxastic logic based on these entities and we show how the belief operators (...) have some desirable properties, while avoiding logical omniscience. A comparison with two well-known proposals (Levesque's logic of explicit and implicit beliefs and Thijsse's hybrid sieve systems) is also provided. (shrink)

El presente artículo presenta una serie de apuntes que buscan una aproximación a la dimensión política del concepto de ritornelo en Deleuze, por ello, no posee un carácter concluyente sino que su única pretensión es mostrar una problemática implícita, nos parece, en el ritornelo y su dimensión política, es decir, la expresión de la dimensión política en la relación del ritornelo con el cuerpo, dicha relación, nos mostraría al acto de resistencia como una alternativa política. Para ello; en el primer (...) apartado se revisan algunas características del ritornelo que, a nuestro criterio, son imprescindibles para comprender su dimensión política. En el segundo apartado presentamos una serie de apuntes que permiten aproximarnos a su dimensión política y al modo como ésta se relaciona con la creación de un Cuerpo sin Órganos problematizando dicha relación y mostrando que ésta se articula a partir de la resistencia como una alternativa política. Este recorrido nos permitirá mostrar en la conclusión que efectivamente existe una relación entre el ritornelo y el cuerpo sin órganos y que es solo a partir de su manifestación en el cuerpo que puede expresarse su dimensión política.

It is well known that the formal system developed by Frege in Begriffsschrift is based upon the distinction between function and argument—as opposed to the traditional distinction between subject and predicate. Almost all of the modern commentaries on Frege's work suggest a semantic interpretation of this distinction, and identify it with the ontological structure of function and object, upon which Grundgesetze is based. Those commentaries agree that the system proposed by Frege in Begriffsschrift has some gaps, but it is taken (...) as an essentially correct formal system for second-order logic: the first one in the history of logic. However, there is strong textual evidence that such an interpretation should be rejected. This evidence shows that the nature of the distinction between function and argument is stated by Frege in a significantly different way: it applies only to expressions and not to entities. The formal system based on this distinction is tremendously flexible and is suitable for making explicit the logical structure of contents as well as of deductive chains. We put forward a new reconstruction of the function-argument scheme and the quantification theory in Begriffsschrift. After that, we discuss the usual semantic interpretation of Begriffsschrift and show its inconsistencies with a rigorous reading of the text. (shrink)

Consideramos que el Ereignis tiene como condición de posibilidad la experiencia del abandono del ser. Por ello, en el centro del viraje no habría ni un giro teológico ni solamente la reciprocidad entre el arrojamiento de lo Dasein por el ser y el proyecto del ser por lo Dasein. Experimentar el abandono del ser exige un salto al abismo, a la nada del ser, lo que abre el esenciar del ser desde su ausencia, tal como se muestra en la figura (...) de la tierra. Este salto implica la transformación del hombre en Dasein: no habría una identidad entre ellos pues lo Dasein no es un ente. Por último, describiremos cómo no habría en esto último una negación de la acción ni de las consideraciones ónticas. (shrink)

En este artículo examino dos excedencias descritas en Totalidad e infinito: el elemento y el rostro. Expongo en primer lugar cómo éstas desbordan lo perceptible, comprensible o domeñable. Mientras que la filosofía del elemento, de acuerdo con mi lectura, permite describir el modo en que hay aquello que es, i.e., el acontecer material de la presencia, el rostro del Otro expone una presencia que no es constituida, sino que se expresa y significa por sí misma. En segundo lugar, explicaré algunos (...) problemas en ambas excedencias que me llevarán a concluir con el carácter teológico de la filosofía levinasiana tanto respecto del Otro como respecto del elemento. Aun así, considero que los análisis levinasianos del elemento son muy fecundos para una fenomenología de la excedencia. (shrink)

This paper focuses on segmenting digital movie and TV series pirates and on investigating the effectiveness of piracy-combatting measures i.e., legal and educational strategies, in light of these segments. To address these research objectives, two online studies were conducted. First, 1277 valid responses were gathered with an online survey. Four pirate segments were found based on differing combinations of attitude toward piracy, ethical evaluation of piracy and feelings of guilt. The anti-pirate, conflicted pirate, cavalier pirate, and die-hard pirate can be (...) placed on a continuum of increasing pirating frequency, subjective norm, pirating self-efficacy, habit, and decreasing in perceived harm, respectively. The segments also differ in deontological and teleological orientations. Second, in an experimental mixed design, we find that the educational strategy is more effective than the legal strategy in lowering pirating intentions for the conflicted and cavalier pirate. However, both strategies fail at lowering intentions of the die-hard pirate, although perceived harm and perceived impunity were significantly influenced. These findings offer a more profound understanding of pirate segments and how they react differently to piracy-combatting measures. As a result, better strategies can be developed to control digital piracy. (shrink)

In the last decades, it has been argued extensively about the possibilities and merits of Social Work to apply at the recognition of its disciplinary character, which -in mind of his defenders- it would overcame the technological and ideological arguments. At the same time, it has been in play h..

Los metalenguajes —lenguajes que tratan de otros lenguajes— tienen algunas propiedades interesantes. En el esfuerzo de crear lenguajes de segundo orden —tales como lenguajes puente entre dos idiomas o dos disciplinas— se pone de relieve la manera particular que tiene un lenguaje de abordar el mundo, así como su materialidad e historicidad. Esta perspectiva facilita la comprensión de las dificultades que entrañan tanto la colaboración entre disciplinas científicas como la traducción literaria. Un aspecto importante del trabajo en humanidades es la (...) creación de metalenguajes, en el contexto de lo que Heidegger llama el “desocultar”; esto es, el constituir el mundo según cierta ontología —al tener esta constitución un peso ético, o sea, que impacta profundamente la forma de vida de la comunidad que desoculta de esta o esta otra manera—. Si se comprende lo que hacen las humanidades respecto a los lenguajes humanos, se comprende mejor su papel y su importancia en la educación, la forma en que facilitan el diálogo entre disciplinas y entre visiones de mundo, la forma en que empoderan a los individuos y las sociedades para articular nuevas formas de desocultar nuevas respuestas a la antiquísima pregunta filosófica: “¿cómo se debe vivir?”.

Whether levonorgestrel taken as an emergency contraceptive has an abortifacient effect is a matter of great importance for Catholic bioethics. While many have argued that LNG-EC does not have a postovulatory effect, a recent literature review has convincingly established that inhibition of ovulation cannot account for all of the pregnancy reduction observed in clinical settings among those who take LNG-EC. This essay proposes a secondary mechanism of action of LNG-EC that is postovulatory but prefertilization; it argues that LNG-EC may act (...) in a contraceptive fashion by interfering with transport of the ovum to the site of fertilization in the timely fashion needed for reproductive success. While this mechanism of action cannot be established with the moral certitude required of these matters of life and death, further research may validate this mechanism beyond a reasonable doubt.

Hoerl & McCormack propose that animals learn sequences through an entrainment-like process, rather than tracking the temporal addresses of each event in a given sequence. However, past research suggests that animals form “temporal maps” of sequential events and also comprehend the concept of ordinal position. These findings suggest that a clarification or qualification of the authors’ hypothesis is needed.

The purpose of this paper is to discuss some of the applications of the interbehavioral model to the system of educational psychology. Some of its foundations are exposed, its application as a logic of theoretical construction, culminating with some characteristics of its technological application, in continuity with the theory of behavior, in the science of psychology. The technological model of didactic discourse is rescued, and its current and potential contributions in the educational field are valued. It is concluded that there (...) is significant potential for the development of interbehavioral thinking in the field of psychology, but researchers need more interest in it. (shrink)

The Multiple Reality theory represents a key piece to understand the socio-phenomenology. It is sustained by a triangulation of the phenomenology of Edmund Husserl, the vitalism of Henry Bergson and the pragmatism of William James (and it has as a background the praxeology of Ludwig Von Mises and ..

La epistemología de Feyerabend desplaza la atención centrada en la dimensión racional de la ciencia para enfocarla en el contexto histórico y sociocultural. Su trabajo da a veces la impresión de un análisis ejecutado por un etnógrafo que se afana en comprender los elementos simbólicos y, en gene..

En este ensayo se revisan algunos de los planteamientos de Imre Lakatos. El examen historiográfico, nos dice Lakatos, ha permitido comprobar que la comunidad científica, ha evaluado como importantes progresos del conocimiento y la investigación a programas que presentaban serias inconsistencias ..

The ideal-type is an empirical generalization of the axiological “must-be”. Its validity rests on an analysis matrix of society which in this article is applied to certain style of action considered as “enterprising”. This article examines the emergence of the “enterprising” type, after grounding th..

In the scope of social sciences (and particularly in the field of sociology) from the Sixties of the last century a series of theories and practices of investigation has arisen with force -these last ones, identified generally like qualitative- that declare to be inspired by the phenomenology (al..
