Cuando hace ahora 40 años terminaba mi carrera universitaria y comenzaba meses después a ser profesora de Ecología en la Universidad de Salamanca, poco se sabía que desde 1968 se había consolidado la Ecología como una nueva área del conocimiento científico, según la UNESCO. Una ciencia, nacida un siglo antes de esa fecha, que serviría ya desde mayo de ese año (mayo del 68), también para definir una ideología nueva del mundo contemporáneo, el ecologismo. Y así, en menos de medio (...) siglo, la ecología ha ido penetrando en la sociedad, tanto en el sistema educativo, desde la enseñanza universitaria a la enseñanza básica y obligatoria, como en la educación no formal (educación popular), además de en otras esferas políticas y sociales.

Spin is a fundamental and distinctive property of the electron, having far-reaching implications. Yet its purely formal treatment often blurs the physical content and meaning of the spin operator and associated observables. In this work we propose to advance in disclosing the meaning behind the formalism, by first recalling some basic facts about the one-particle spin operator. Consistently informed by and in line with the quantum formalism, we then proceed to analyse in detail the spin projection operator correlation function \=\left\langle (...) \left \left \right\rangle \) for the bipartite singlet state, and show it to be amenable to an unequivocal probabilistic reading. In particular, the calculation of \\) entails a partitioning of the probability space, which is dependent on the directions \.\) The derivation of the CHSH- or other Bell-type inequalities, on the other hand, does not consider such partitioning. This observation puts into question the applicability of Bell-type inequalities to the bipartite singlet spin state. (shrink)
El sufrimiento existencial en el paciente oncológico en estadio avanzado: dimensiones y ejes vertebradores para la intervención psicológica Sofrimento existencial no paciente oncológico em estágio avançado: dimensões e eixos vertebrais para intervenção psicológica The relief of existential suffering in the patients with adavanced cancer is a first-order therapeutic goal. The present work suggests some axis on which psychotherapeutic intervention could be developed, in order to facilitate in these patients: 1) The experience of: In spite of the "existing" limited situation, one's (...) life "still" has meaning, 2) Positive emotional experiences that promote well-being and quality of life, and 3) Face the serious illness that will cause one's almost imminent death, through the development of a serene, reconciled attitude with life and integrating with oneself and the others.

Research on adolescent-to-parent violence associates specific psychosocial characteristics with adolescents who assault their parents, whether they are within or outside the juvenile justice system, or whether these characteristics are shared by other adolescents convicted of other crimes. The aim of this paper is to compare three groups of adolescents. Those who have been sentenced for APV are compared with adolescents who have committed other crimes, and with a group who have not been involved in the justice system. The sample used (...) consists of 148 male participants between the ages of 14 and 21. A comparison is made regarding type of self-reported behavior, frequency of drug use, academic performance, exposure to violence, self-concept, and parents’ conflict resolution tactics. The results obtained indicate that adolescents with judicial measures, regardless of the crime committed, differ from those who have not been in trouble with the justice system in terms of them having suffered violence in the street, the frequency with which they use drugs and in their academic achievement. Likewise, adolescents convicted of APV differ from the other two groups in the frequency with which they are victims of violence at home, in that their mothers use the tactic of asking somebody else for help as a way of solving marital conflicts, and in having a more negative family self-concept. The results are discussed highlighting the importance of taking into account whether a sample is judicial, clinical, or community, and the specific APV behaviors which are measured. (shrink)
This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation (...) and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

ABSTRACTThe ‘Scientific Culture at Enterprises’ project aims to identify the different factors that characterize the image of science held by entrepreneurs and business managers, explore the relationships among these factors, and shed light on the role they play in defining this image and ultimately in developing a culture of science in the business sector. This article is based on the results of the SCe 2016 survey with a specially designed telephone survey questionnaire of a representative sample of Spanish companies. The (...) novelty of our approach lies in the application of a model developed in the fields of Social Studies of Science and Public Understanding of Science to the business sector, in order to obtain information on the dispositions of perception, interest, knowledge and action and their relationships with science and innovation in the business sector in Spain. Using the PIKA model of the image of science, we found this image in the business sector to be shaped by entrepreneurs... (shrink)
La tesis de este trabajo es que las notas del narrador revelan la importancia y centralidad de la muerte de Jesús en el evangelio de Juan. Estas notas guían al lector para que descubra su significado y sus consecuencias. En primer lugar, se define el concepto de nota del narrador. A continuación se describen aquellas notas que se refieren a la muerte de Jesús en el relato. En un tercer momento se analiza el lugar que ocupan en la (...) trama del evangelio y el papel que desempeñan en ella. Por último, se explica cómo el narrador interpreta en estas notas la muerte de Jesús y relee de forma nueva y creativa visiones tradicionales, mostrando así una visión específica de la misma en el evangelio joánico.

This article is based on a perspective on circulation of knowledge that allows the consideration of science as the result of the encounter between diverse communities. We tell a story that constantly changes places, scales, and cultures in order to stress the importance of networks as an alternative to the centre/periphery trope, which entangles world histories of science. The result is a picture much more complex and intertwined than the one suggested by these simplifying dichotomies. We focus on a case (...) study that illuminates the process of knowledge production in non-European spaces of modernity. The return of the Society of Jesus to the newly independent nation-states of Latin America is the point of departure to analyse the circulation of a specific scientific idea in Ecuador: Darwin’s theory of biological evolution through natural selection. The article follows the paths of three different knowledge makers whose encounters are seen as sites of knowledge production: a religious order, a Latin American... (shrink)
The purpose of this paper is to present a formalization of the language, semantics and axiomatization of justification logic in Coq. We present proofs in a natural deduction style derived from the axiomatic approach of justification logic. Additionally, we present possible world semantics in Coq based on Fitting models to formalize the semantic satisfaction of formulas. As an important result, with this implementation, it is possible to give a proof of soundness for $\mathsf{L}\mathsf{P}$ with respect to Fitting models.
En la actualidad, los desarrollos teóricos acerca de la justicia desde una perspectiva lingüística giran alrededor de la teoría de la justicia de John Rawls y la teoría de la acción comunicativa de Jürgen Habermas. Empero, aunque un estudio detallado del funcionamiento del lenguaje hace parte de estas teorías no pueden concebirse propiamente como filosofías del lenguaje. La filosofía del lenguaje propende por la construcción de una teoría del significado que permita explicar diferentes fenómenos lingüísticos entre los que se encuentran (...) aquellos donde es usado el concepto de justicia. Mientras estas teorías permiten comprender las dinámicas pragmáticas de estos fenómenos, quedan cortas en la comprensión del contenido semántico del concepto. Este contenido semántico es lo que en última instancia aclara la naturaleza del mismo y, por tanto, una teoría del significado que permita dar cuenta tanto de las dinámicas pragmáticas como del contenido semántico será de vital importancia en la aclaración del concepto de justicia. Según este panorama, una salida más viable podría encontrarse en el pensamiento de Robert Brandom y Charles Travis, cuyas teorías del significado están basadas en el pensamiento expuesto en la obra tardía del filósofo Ludwig Wittgenstein. Según este autor, las prácticas de la justicia hacen parte de nuestras formas de vida y si el contenido semántico del concepto de justicia ha de ser buscado en algún lugar, es allí, en esas prácticas, donde será encontrado. La trama de la vida misma es la luz adecuada que puede iluminar la oscuridad en la que se ha sumido el concepto de justicia. Currently, the theoretical developments about justice from a linguistic perspective revolve around the theory of justice of John Rawls and the theory of communicative action of Jürgen Habermas. However, although a detailed study of the functioning of language is part of these theories, they can not be properly conceived as philosophies of language. The philosophy of language tends to the construction of a theory of meaning that allows explaining different linguistic phenomena among which are those where the concept of justice is used. While these theories allow to understand the pragmatic dynamics of these phenomena, they are short in the understanding of the semantic content of the concept. This semantic content is what ultimately clarifies the nature of it and, therefore, a theory of meaning that allows to account both the pragmatic dynamics and the semantic content will be of vital importance in the clarification of the concept of justice. According to this panorama, a more viable exit could be found in the thought of Robert Brandom and Charles Travis, whose theories of meaning are based on the thought expressed in the later work of the philosopher Ludwig Wittgenstein. According to this author, the practices of justice are part of our forms of life and if the semantic content of the concept of justice has to be sought somewhere, it is there, in those practices, where it will be found. The plot of life itself is the adequate light that can illuminate the darkness in which the concept of justice has been submerged. (shrink)
