The problem of the electromagnetic coupling for spin-3/2 particles is discussed. Following supergravity and some previous researches in the field of classical supersymmetric particles, we found that the electromagnetic coupling must not obey a minimal coupling in the sense of coupling the electromagnetic potential, but some kind of an electromagnetic field strength.

This paper explores the idea of linguistic meaning in the case of metaphysical referents or entities, quoting Plato's view assumed by Wittgenstein that there couldn't be a language for metaphysical referents like the Good or God. In order to expose the conceptual situation recourse is made to the thesis of a Logical Proper Name and to the thesis of Private Names as contrasting views of the nature of names and language. Furthermore, it is surmised that the Wittgenstein view helps to (...) realise why there cannot be metaphysical arguments. But all of that is presented in a very sketchy way and has to wait for further development. (shrink)

100 años después de la primera edición de la Defensa de la hispanidad de Ramiro de Maeztu, pocos son los que no asocian la obra con el franquismo más rancio. Sin embargo, cuando uno tropieza sin prejuicios con la obra, casi por casualidad, puede encontrar en ella un llamamiento a algo más profundo que los anhelos de un mundo decimonónico y oscuro, donde la ley de Dios lo dirige todo inflexiblemente. Sin poder negar el rigorismo católico del vitoriano, encontramos en (...) sus páginas un encuentro íntimo con las raíces de España y la Hispanidad, de una España y una Hispanidad que, según el autor, han perdido el norte, análisis que podemos compartir en mayor o menor medida según los argumentos de Maeztu, que iremos desgranando a lo largo del artículo. Posteriormente concluiremos que, aunque parte de su discurso ha de ser tomado con cautela, buena parte de la obra sigue teniendo vigencia y ha de ser tenido en cuenta en cualquier intento de regeneración ideológica de nuestro país o de la Hispanidad en conjunto.

This is the third volume of the new series Social, Political, & Legal Philosophy and it deals with the relationship between Law and The Philosophy of Action. In this volume a number of legal issues are illuminated by resource to the analysis of mental concepts. Issues in Criminal Law, Contract Law, Acceptance of Legal Systems, and the nature of Legal Norms are some of the main issues dealt in the papers that constitute the volume. Conceptual analysis is used and new (...) overtures are made into current findings in the Cognitive Sciences. All of this results in illuminating accounts that throw new light on traditional fundamental legal issues. This volume is a precursor in the powerful theorizing of the Cognitive Sciences that is being brought to bear in the Philosophy of Mind and in the theory of Law, and this theorizing will increase in the coming years.

La llegada de inteligencias artificiales ―que acompañen a las personas vulnerables e incluso sean nuestros amigos y amantes, por ejemplo― es cada vez menos un sueño lejano, por lo que muchas de estas cuestiones éticas han de plantearse en un horizonte temporal a medio plazo, entre los problemas actuales y la hipotética llegada de la inteligencia artificial general. Plantearse las cuestiones correctas es una labor muy complicada en general, y más si cabe en el campo de la inteligencia artificial, lleno (...) de declaraciones y anuncios rimbombantes por parte de expertos, conspiraciones y miedos basados en las historias de ciencia ficción y un temor bien fundado a la luz del creciente número de escándalos causados por las malas prácticas de los proveedores de servicios a la hora de gestionar los datos que extraen de nuestra actividad en la red. La intención del presente trabajo es exponer una serie de problemas cuyo tratamiento normalmente queda en un segundo plano en la bibliografía a favor de otros debates, con el fin de contribuir a una visión más informada y crítica de la tecnología que parece que está por llegar para combatir el escepticismo basado en creencias de ciencia ficción y despertar un escepticismo bien informado.

Hockenhull y Leavitt Cohn introducen en su análisis de la escena tecnológica danesa el concepto de «aire caliente» para describir las medias verdades y exageraciones que las compañías utilizan para atraer la atención pública y la inversión. La ciencia ficción y los anuncios de las empresas del sector tecnológico describen con frecuencia a los robots del futuro como seres inteligentes y con capacidad de sentir y, por tanto, con la capacidad de sustituir a las personas como amantes y compañeros de (...) vida. El presente artículo tendrá como objetivo analizar estas expectativas presentes en los imaginarios sociotécnicos de la inteligencia artificial con la intención de descubrir sus problemas y facilitar un juicio menos inflado de «aire caliente».
