Relativistic geometrical action for a quantum particle in the superspace is analyzed from theoretical group point of view. To this end an alternative technique of quantization outlined by the authors in a previous work and that is based in the correct interpretation of the square root Hamiltonian, is used. The obtained spectrum of physical states and the Fock construction consist of Squeezed States which correspond to the representations with the lowest weights $\lambda=\frac{1}{4}$ and $\lambda=\frac{3}{4}$ with four possible (non-trivial) fractional representations (...) for the group decomposition of the spin structure. From the theory of semigroups the analytical representation of the radical operator in the superspace is constructed, the conserved currents are computed and a new relativistic wave equation is proposed and explicitly solved for the time-dependent case. The relation with the Relativistic Schrödinger equation and the Time-dependent Harmonic Oscillator is analyzed and discussed. (shrink)

Este artículo indaga en el Curso de dos lecciones sobre lo estético, titulado Reflexiones filosóficas sobre lo estético, un «hilo teórico» muy poco estudiado por los especialistas. Este Curso que realizó Zubiri en 1975, estaba muy mayor, se analiza cómo se muestra lo más radical para entender lo estético desde sus categorías filosóficas, pero de la «mano invisible» de Hegel. No se trata del Hegel que critica explícitamente Zubiri y que se coloca siempre de forma muy distante al pensador alemán, (...) sino de lo categorial mismo del pensamiento hegeliano que Zubiri «echa mano» para mostrar cómo opera lo más propio de su pensamiento para dar cuenta del complejo tema de la articulación de lo estético y la realidad. Aquí vemos que el pensamiento de Hegel tiene mucho que aportar para poder entender lo estético mismo. Y esto, incluso, más allá de lo que el mismo Hegel, como pensador de su tiempo, filosofaba respecto del tema del arte y/ o lo estético. (shrink)

The physical meaning of the particularly simple non-degenerate supermetric, introduced in the previous part by the authors, is elucidated and the possible connection with processes of topological origin in high energy physics is analyzed and discussed. New possible mechanism of the localization of the fields in a particular sector of the supermanifold is proposed and the similarity and differences with a 5-dimensional warped model are shown. The relation with gauge theories of supergravity based in the OSP(1/4) group is explicitly given (...) and the possible original action is presented. We also show that in this non-degenerate super-model the physic states, in contrast with the basic states, are observables and can be interpreted as tomographic projections or generalized representations of operators belonging to the metaplectic group Mp(2). The advantage of geometrical formulations based on non-degenerate super-manifolds over degenerate ones is pointed out and the description and the analysis of some interesting aspects of the simplest Riemannian superspaces are presented from the point of view of the possible vacuum solutions.

This article reviews recent developments in health care law, focusing on the engagement of law as a partner in health care innovation. The article addresses: the history and contents of recent United States federal law restricting the use of genetic information by insurers and employers; the recent federal policy recommending routine HIV testing; the recent revision of federal policy regarding the funding of human embryonic stem cell research; the history, current status, and need for future attention to advance directives; the (...) recent emergence of medical–legal partnerships and their benefits for patients; the obesity epidemic and its implications for the child’s right to health under international conventions.

Este artículo busca pensar los orígenes de la Técnica moderna en la vida y obra del científico pisano Galileo Galilei a la luz de dos ideas fundamentales, por una parte, lo acontecido en la propia época de Galileo y, por otra parte, en la categoría fundamental de «experimentación» como «probación física de la realidad» que aparece en la obra Inteligencia y razón de Xavier Zubiri. Desde esta categoría de análisis podremos ver la riqueza de la inicial investigación científico-técnica de Galileo (...) y cómo ésta ha sido decisiva en el desarrollo ulterior de la investigación humana a lo largo de la Historia.

El objetivo de este artículo es estudiar el Curso de Xavier Zubiri de 1975 Reflexiones sobre lo estético a la luz de la “noología”, horizonte de pensamiento que el autor español dejó planteado al final de su vida. Allí lo estético cobra otra dimensión en su estudio al vincular las tres esferas de la noología: la aprehensión primordial de la realidad, el logos sentiente y la razón sentiente. A partir de estas tres categorías cardinales, vemos lo estético en un primer (...) nivel de la aprehensión misma, otro segundo nivel en donde lo estético se diseña y son las artes las que expresan lo fruitivo de la realidad y por último, un tercer nivel que son las obras de arte propiamente dichas.

The Purpose in Life Test is a measure of purpose in life widely used in many cultures and countries; however, cross-cultural assessments are scarce. The present study aimed to evaluate the cross-cultural measurement invariance of the PIL in the general population of seven Latin American countries. A total of 4306 people participated, selected by non-probabilistic convenience sampling, where Uruguay has the highest mean age ; while Ecuador has the lowest mean age. Furthermore, in each country, there is a higher proportion (...) of women than men. Using Multi-Group Confirmatory Factor Analysis, the factorial structure does not show evidence of invariance among the included countries. However, based on the Multi-Group Factor Analysis Alignment, there is evidence that a three-dimensional structure of the PIL is the same in the participating countries. Results based on item response theory indicate that most PIL items can significantly differentiate responses according to the level of life purpose. In addition, people with low life purpose will tend to choose the lower response alternatives on the PIL; while people with higher life purpose will choose higher response alternatives. The findings indicate that the PIL has the potential to increase knowledge about how people conceive and experience their purpose in life in different countries. (shrink)

In Genesis 27 Jacob is depicted as lying to Isaac. Jacob, however, was held in Christian tradition to be both a moral exemplar and to be speaking prophetically in this episode with his father. This raises the question of how Doctors of the Church such as St. Augustine and St. Thomas Aquinas were able reconcile these interpretive commitments with their stance on the intrinsically disordered nature of lying. In examining their resolution of this tension, we discover an important exegetical distinction (...) for interpreting troubling words as nevertheless being divinely inspired. Yet, it is only in light of another interpretive distinction, recently highlighted by Nicholas Lombardo OP, that we can both hold to the inspired nature of Jacob's words and also a natural reading of the account in Genesis 27. The detailed examination of Genesis 27 by both Augustine and Aquinas is an important case study for understanding how we can interpret troubling language as still being the word of God. This undertaking, spanning centuries between Augustine and Aquinas, is now taken one step further thanks to the exegetical proposal of Fr. Lombardo. (shrink)
