The general fact of the impossibility of a bivalent, truth-functional semantics for the propositional structures determined by quantum mechanics should be more subtly demarcated according to whether the structures are taken to be orthomodular latticesP L or partial-Boolean algebrasP A; according to whether the semantic mappings are required to be truth-functional or truth-functional ; and according to whether two-or-higher dimensional Hilbert spaceP structures or three-or-higher dimensional Hilbert spaceP structures are being considered. If the quantumP structures are taken to be orthomodular (...) latticesP L, then bivalent mappings which preserve the operations and relations of aP L must be truth-functional . Then as suggested by von Neumann and Jauch-Piron and as proven in this paper, the mere presence of incompatible elements in aP L is sufficient to rule out any semantical or hidden-variable proposal which imposes this strong condition, for anytwo-or-higher dimensional Hilbert spaceP L structure. Thus from the orthomodular lattice perspective, the peculiarly non-classical feature of quantum mechanics and the peculiarly non-Boolean feature of the quantum propositional structures is the existence of incompatible magnitudes and propositions. However, the weaker truth-functionality condition can instead be imposed upon the semantic or hidden-variable mappings on theP L structures, although such mappings ignore the lattice meets and joins of incompatibles and preserve only the partial-Boolean algebra structural features of theP L structures. Or alternatively, the quantum propositional structures can be taken to be partial-Boolean algebrasP A, where bivalent mappings which preserve the operations and relations of aP A need only be truth-functional (c). In either case, the Gleason, Kochen-Specker proofs show that any semantical or hidden variable proposal which imposes this truth-functionality (c) condition is impossible for anythree-or-higher dimensional Hilbert spaceP A orP L structures. But such semantical or hidden-variable proposals are possible for any two dimensional Hilbert spaceP A orP L structures, in spite of the presence of incompatibles in these structures, in spite of the fact that Heisenberg's Uncertainty Principle applies to the incompatible elements in these structures, and in spite of the fact that these structures are non-Boolean in the Piron sense.

The final portion of the thesis surveys proposals for the introduction of hidden variables into quantum mechanics, proofs of the impossibility of such hidden-variable proposals, and criticisms of these impossibility proofs. And arguments in favour of the partial-Boolean algebra, rather than the orthomodular lattice, formalization of the quantum propositional structures are reviewed. ;As for , each quantum state-induced expectation-function on a P truth-functionally assigns 1 and 0 values to the elements in a ultrafilter and dual ultraideal of P, where in (...) general the union of an ultrafilter and its dual ultraideal is smaller than the entire structure. Thus it is argued that each expectation-function is the quantum analog of a classical semantic mapping, even though the domain where each expectation-function is bivalent and truth-functional is usually a non-Boolean substructure of P. ;In classical propositional logic, propositions form a Boolean algebra, and each semantic mapping assigns the value 1 to the members of a certain subset of the algebra, namely, an ultrafilter, and assigns 0 to the members of the dual ultraideal, where the union of these two subsets is the entire algebra. The propositional structures of classical mechanics are likewise Boolean algebras, so one can straightforwardly provide a classical semantics, which also satisfies . However, quantum propositional structures are non-Boolean, so it is an open question whether a semantics satisfying , and can be provided. ;Von Neumann first proposed that the algebraic structures of the subspaces of Hilbert space be regarded as the propositional structures P of quantum mechanics. These structures have been formalized in two ways: as orthomodular lattices which have the binary operations "and", "or", defined among all elements, compatible and incompatible ; and as partial-Boolean algebras which have the binary operations defined among only compatible elements. In the thesis, two basic senses in which these structures are non-Boolean are discriminated. And two notions of truth-functionality are distinguished: truth-functionality ,) applicable to the Plattices; and truth-functionality ) applicable to both the Plattices and partial-Boolean algebras. Then it is shown how the lattice definitions of "and", "or", among incompatibles rule out a bivalent, truth-functional ,) semantics for any PQM lattice containing incompatible elements. In contrast, the Gleason and Kochen-Specker proofs of the impossibility of hidden-variables for quantum mechanics show the impossibility of a bivalent, truth-functional ) semantics for three-or-higher dimensional Hilbert space PQM structures; and the presence of incompatible elements is necessary but is not sufficient to rule out such a semantics. ;The thesis investigates the possibility of a classical semantics for quantum propositional structures. A classical semantics is defined as a set of mappings each of which is bivalent, i.e., the value 1 or 0 is assigned to each proposition, and truth-functional, i.e., the logical operations are preserved. In addition, this set must be "full", i.e., any pair of distinct propositions is assigned different values by some mapping in the set. When the propositions make assertions about the properties of classical or of quantum systems, the mappings should also be "state-induced", i.e., values assigned by the semantics should accord with values assigned by classical or by quantum mechanics.

In the midst of the global financial crisis and in the ‘anti-race era’, Europe has witnessed a revival of deeply racialized discourses targeting the Roma, leading to new discriminatory practices and legitimating existing ones in many social domains. While westward Roma immigration has spurred these discourses, it has also favored the emergence of invisible grassroots reactions against them that need to be further analyzed. Drawing on interviews with migrant Romani women, this article aims to shed light on these unknown processes, (...) as experienced by women in Romani women-based solidarity networks. Data show that these networks help the women to access basic social facilities, while also challenging the abovementioned racialized discourses. (shrink)

Resumen: El presente artículo pretende analizar el discurso empleado por las voces líricas femeninas de las elegías anglosajonas medievales The Wife’s Lament y Wulf and Eadwacer. Mediante la idea de la conciencia del cuerpo femenino como origen de la écriture féminine propuesta por Luce Irigaray y Hélène Cixous, figuras principales del feminismo de la “diferencia” francés, se determinará que el uso discursivo empleado por las voces elegíacas femeninas diverge en cuanto al utilizado por voces elegíacas masculinas y que, de este (...) modo, supone un medio por el que hallar una identidad femenina propia más allá de los constructos de género patriarcales vigentes en la sociedad anglosajona medieval. Abstract: This article aims to analyse the discourse employed by the female lyrical voices in the medieval Anglo-Saxon elegies The Wife’s Lament and Wulf and Eadwacer. Through the idea of female body self-awareness as the origin of écriture féminine proposed by Luce Irigaray and Hélène Cixous, leading figures in French feminism of the sexual “difference”, we will determine that the discursive use applied by female elegiac voices diverges from that used by male elegiac voices and that, thus, it provides a means to find a female identity beyond the patriarchal gender constructs of medieval Anglo-Saxon society.

One of the psychological responses to audiovisual fictions that has been receiving more attention recently is appreciation, defined as a reflexive eudaimonic gratification obtained from a meaningful entertainment mode. Appreciation is the perception that the media experience has a profound meaning, has taught or revealed something. This study seeks to advance on the understanding of appreciation by youngsters. It translates and adapts the Oliver and Bartsch’s questionnaire for teenagers of three European countries. A total of 213 Italians, 55 Spaniards and (...) 42 Germans watched a drama film and immediately afterwards answered the questionnaire. The results of confirmatory factor analysis suggest the existence of four first-order factors for each country. The multi-group analysis shows the questionnaire is not invariant across groups. Thus, the concept of appreciation in its current formulation is not universal. Instead, it seems to be dependent on the cultural aspects of the audience. This article discusses the implications of such results for the understanding of appreciation and of teenagers’ media responses. It also reports mean comparisons for the invariant parameters.

The informed consent is an ethical and legal requirement for potential participants to enroll in a study. There is ample of evidence that understanding consent information and enrollment is challenging for participants in clinical trials. On the other hand, the reasoning process behind decision-making in HIV clinical trials remains mostly unexplored. This study aims to examine the decision-making process of people living with HIV currently participating in antiretroviral clinical trials and their understanding of informed consent. We conducted a qualitative socio-constructivist (...) study using semi-structured interviews. Eleven participants were selected by purposive sampling in Argentina until data saturation was reached. A content analysis was performed. The findings highlight the fact that some participants decided to enroll on the spot, while others made the decision a few days later. In all cases, the decision was based on different aspects of trust (in doctors, in the clinical research site, in the clinical trials system) but also on emotions associated with HIV and/or treatment. Moreover, while people living with HIV felt truly informed after the consent dialogue with a researcher, consent forms were unintelligible and unfriendly. The immediacy of patient decision-making has rarely been described before. Enrollment in an HIV clinical trial is mainly a trust-based decision but this does not contradict the ethical values of autonomy, voluntariness, non-manipulation, and non‐exploitation. Thus, trust is a key issue to be included in reshaping professional practices to ensure the integrity of the informed consent process. (shrink)

Previous scientific contributions show that interactive learning environments have contributed to promoting learners' learning and development, as interaction and dialogue are key components of learning. When it comes to students with special needs, increasing evidence has demonstrated learning improvements through interaction and dialogue. However, most research focuses on children's education, and there is less evidence of how these learning environments can promote inclusion in adult learners with SEN. This article is addressed to analyse a case study of an interactive learning (...) environment shared by adults with and without special needs. This case shows several improvements identified by adult learners with special needs participating in this study. Based on a documental analysis and a qualitative study, this study analyses a context of participatory and dialogic adult education. From the analysis undertaken, the main results highlight some improvements identified in the lives of these adult women and men with SEN, covering educational improvements, increased feeling of social inclusion, and enhanced well-being.

Este artículo muestra varios detalles para entender la compleja figura de Ariadna en el pensamiento de Nietzsche, pero que va más allá del autor alemán y se sumerge en ciertos momentos de Ariadna, desde lo etimológico a Otto pasando por Ovidio y Catulo, para dar cuenta de una Ariadna que es la compañera del dios Diónysos y que en cierta forma posibilita la propia verdad del dios; lo que Nietzsche llamaría “eterno retorno”.

Para ofrecer una ruta de lectura del pensamiento feminista-deleuziano, se pone a discusión el concepto cartografía propuesto por Braidotti, respecto a la recepción y reelaboración de la inmanencia radical, y la diferencia sexual en la filosofía actual. Se propone un símil de dicha recepción en la teoría y estudios del arte, particularmente en México. A través de Metamorfosis. Hacia una teoría materialista del devenir y los conceptos clave como devenir-mujer y devenir-insecto, se entabla una relación con los feminismos visuales situados (...) en el sur global. El diálogo entre ambas recepciones, la filosófica y la artística, implica un acercamiento a la problematización y comprensión del conflicto capital-vida, además de las aportaciones posibles de la producción feminista, hace patente cómo se continúa en la teoría feminista actual una línea materialista, con profundas raíces clásicas, de una ontología del cuerpo. Palabras clave: inmanencia radical, devenir animal, metamorfosis, diferencia sexual. (shrink)

Desde los propios tiempos de su constitución y en no poca medida todavía hasta el presente, el paradigma general del idealismo poskantiano ha sido objeto de numerosos malentendidos. La historia estándar de la Filosofía Moderna dominante sobre todo en los países de habla inglesa tiende a ver a la filosofía de Kant como el límite máximo de idealismo capaz de ser asimilado de forma consistente por la reflexión filosófica. A partir de Kant, la radicalización del motivo idealista en las filosofías (...) de Fichte, Schelling y Hegel ha sido así considerada a menudo como un abandono de los patrones viables de racionalidad. En la base de esta visión no es en modo alguno inusual encontrar la confusión del idealismo poskantiano con una forma desorbitada y excéntrica del idealismo de Berkeley. Sin embargo, el proyecto teórico de radicalización del idealismo trascendental de Kant poco tiene que ver con esta interpretación. Una de las claves principales para poder entender correctamente ese proyecto es comprender su particular teoría sobre la relación entre conocimiento sensible y conocimiento intelectual, entre intuición y concepto. En el marco teórico de un idealismo absoluto se abandona la diferenciación radical entre intuición y concepto y con ello se excluye por principio la posibilidad de resolver el problema de la referencia de la mente humana al mundo mediante una concepción empirista del conocimiento sensible. En este nuevo contexto, el problema del vínculo de lo mental y lo real debe ser resuelto en el propio plano inmanente de los conceptos. El objetivo de nuestra ponencia será justamente analizar, con ocasión de la teoría de Hegel sobre la relación entre intuición y concepto, los presupuestos teóricos que hacen plausible una concepción de la relación entre la mente y el mundo que no apela para justificar esa relación a categorías como la de receptividad y causalidad.

La filosofía ofrece múltiples ópticas para considerar el curso de la historia de la humanidad, perspectivas que van desde lo epistemológico hasta lo metafísico. Entre aquellas posibilidades interpretativas se encuentra el juego, específicamente la concepción antropológica del ser humano en tanto homo ludens –tema ya trabajado por Holzapfel en una obra previa–. A partir de dicha concepción lúdica del ser humano es posible analizar la dialéctica de los diversos tipos de juegos en el desarrollo histórico. La presente obra constituye una (...) invitación a recorrer el despliegue del homo ludens hasta las repercusiones de su desregulación agonal (juego de competencia) en nuestros días, proponiendo una solución lúdica a la crisis actual.

En este libro Pedro Karczmarczyk se da a la tarea de recopilar ―además de colaborar con un texto propio― una serie de artículos que abordan las principales tradiciones de la filosofía contemporánea, en especial sobre un tema que se encuentra en el meollo del pensamiento filosófico: la cuestión del sujeto. Podemos pensar entonces que el título, El sujeto en cuestión, evoca de manera certera lo común que atraviesa la diversidad de enfoques; volviéndose el hilo de Ariadna que nos ayuda (...) a caminar por un laberinto poblado de gigantes filosóficos que, como es su célebre y problemática costumbre, hablan su propio idioma. Este cuestionamiento sobre la multívoca categoría de ‘sujeto’ (vocablo que ha sido entendido como sustrato-súbdito-sujeto de la consciencia entre otros) comienza con la necesaria ruptura respecto del espíritu filosófico moderno que creyó fervientemente en la posibilidad de delimitar ―y agotar― los modos y los medios a través de los cuales la consciencia (el sujeto) es capaz de representar el mundo. Cénit de este modo de pensar fue la filosofía de Kant, referente ineludible de muchos de los autores analizados en el presente libro que de un modo u otro se enfrentan a la pretensión fundacionista, ahistoricista y universalista de nuestro pasado filosófico.
