The early controversies surrounding the axiom of choice are well known, as are the many results that followed concerning its dependence from, and equivalence to, other mathematical propositions. This paper focuses not on the logical status of the axiom but rather on showing why it fails in certain categories.

Este trabajo esboza una forma de justificar el principio estructurador central de una teoría veritista de la evaluación epistémica, en respuesta a críticas planteadas por Eleonora Cresto a mi defensa del veritismo frente a una serie de objeciones en el sentido de que no es capaz de explicar la naturaleza y el valor del entendimiento. La primera sección presenta el esbozo de justificación del núcleo de una teoría veritista; la segunda responde a críticas más específicas de Cresto. This paper sketches (...) a way to justify the central tenet of a veritistic theory of epistemic evaluation, in response to problems raised by Eleonora Cresto concerning my defense of veritism, against a series of objetions to the effect that veritistic epistemology is uncapable of explaining the nature and value of understanding. The first section presents the sketch of justification of the nucleus of a veritistic theory, the second responds to some of Cresto's more specific criticisms. (shrink)

In 1908 the German mathematician Ernst Zermelo gave an axiomatization of the concept of set. His axioms remain at the core of what became to be known as Zermelo-Fraenkel set theory. There were two axioms that received diverse criticisms at the time: the axiom of choice and the axiom of separation. This paper centers around one question this latter axiom raised. The main purpose is to show how this question might be solved with the aid of another, more recent mathematical (...) theory of sets which, like Zermelo’s, has numerous philosophical underpinnings. Keywords: properties of sets, foundations of mathematics, axiom of separation, subobject classifier, truth values. (shrink)

RESUMEN: En este artículo tratamos de hacer plausible la hipótesis de que las conectivas de diferentes lógicas no necesariamente difieren en significado. Utilizando el tratamiento categorista de las conectivas, argumentaremos contra la tesis quineana de que la diferencia de lógicas implica diferencia de significado entre sus conectivas, y ubicamos el cambio de tema en la diferencia de objetos más que en una tal diferencia de significado. Finalmente, intentamos mostrar que ese tratamiento categorista es una forma de minimalismo semántico, de acuerdo (...) con el cual no todos los elementos semánticos usuales son relevantes para determinar el significado de las conectivas.ABSTRACT: We argue here that the meanings of logical connectives need not differ in different logics. treatment of the logical connectives, we argue against the well-known Quinean thesis that a difference between logics implies a difference in the meanings of connectives. We thus locate this change in the difference between certain objects rather than in the difference between the meaning of connectives. Finally, we try to show that the category-theoretic treatment of logical connectives is a form of semantic minimalism, according to which not all the usual semantic components are relevant in fixing the meaning of a connective.

All rights reserved.Cell walls of grasses, including cereal crops and biofuel grasses, comprise the majority of plant biomass and intimately influence plant growth, development and physiology. However, the functions of many cell wall synthesis genes, and the relationships among and the functions of cell wall components remain obscure. To better understand the patterns of cell wall accumulation and identify genes that act in grass (...) cell wall biosynthesis, we characterized 30 samples from aerial organs of rice at 10 developmental time points, 3-100 d post-germination. Within these samples, we measured 15 cell wall chemical components, enzymatic digestibility and 18 cell wall polysaccharide epitopes/ligands. We also used quantitative reverse transcription-PCR to measure expression of 50 glycosyltransferases, 15 acyltransferases and eight phenylpropanoid genes, many of which had previously been identified as being highly expressed in rice. Most cell wall components vary significantly during development, and correlations among them support current understanding of cell walls. We identified 92 significant correlations between cell wall components and gene expression and establish nine strong hypotheses for genes that synthesize xylans, mixed linkage glucan and pectin components. This work provides an extensive analysis of cell wall composition throughout rice development, identifies genes likely to synthesize grass cell walls, and provides a framework for development of genetically improved grasses for use in lignocellulosic biofuel production and agriculture.

Se aborda la crítica que realiza Nélida Piñon, desde la postura de la teoría feminista que rompe con los esquemas tradicionales de la subordinación de la mujer en la cultura occidental; deconstruye la dicotomía hombre-mujer a través de un lenguaje poético erotizado que parte del cuerpo de la mujer para articular su propia experiencia. Esto lo convierte en texto clave dentro de la tradición de la escritura femenina.

Resumen En este artículo se examina el Darwinismo Neural en su explicación de la evolución de la conciencia humana, contrastando su metodología con la utilizada por Richard Lewontin, Richard Levins y Steven Rose, quienes han hecho importantes aportaciones en el estudio de los sistemas vivos desde un punto de vista dialéctico. Concluimos que la explicación interaccionista de la evolución de la conciencia planteada en el DN, supera muchas de las deficiencias del determinismo biológico; sin embargo, al compartir algunos lineamientos con (...) el cartesianismo, mantiene un carácter a-histórico insuficiente para la explicación de la conciencia humana. Finalmente, proponemos la adopción de una teoría explicativa de la conciencia humana que considere las relaciones existentes en ella, no sólo como interacciones sino también como interpenetraciones ontogénicas y filogenéticas.This article examines Neural Darwinism proposed as an explanation of evolution of human consciousness. His methodology is contrasted with that used by Richard Lewontin, Richard Levins, and Steven Rose, who made important contributions to the study of living systems from a dialectical point of view. We conclude that the interactionist explanation of the evolution of conscience put forward in ND overcomes many of the deficiencies proper to biological determinism. However, as ND also shares many of the foundations of the Cartesian approach, it maintains a non-historical character, insufficient for the account of human consciousness. We suggest the adoption of an alternative theory, able to fully explain human conscience which must consider the whole of existing relations in it, and, instead of merely considering them as interactions, they have to be observed as dialectical interpenetrations.

In the business ethics literature, the growing interest in social entrepreneurship has remained limited to the assumption that pursuing a social mission will clash against the pursuit of associated economic achievements. This ignores recent developments in the social entrepreneurship literature which show that social missions and economic achievement can also have a mutually constitutive relation. We address this gap adopting the notion of shared value for an ethical inquiry of social entrepreneurship. Using a sensemaking framework, we assume that the emergence (...) of SV propositions can be captured through the analysis of how social entrepreneurs make sense of events of change, selecting the journey of three exemplar cases for an inductive empirical inquiry. From our findings, we propose three themes for further examination. First, the ethical groundings of entrepreneurial SV are mostly shaped by idiosyncratic imperatives that inform both social mission and economic gain from the onset. Second, the ethical groundings of entrepreneurial SV will be likely operationalised as a filtering device, which allows for resilience as well as potentially detrimental blind spots. And third, the ethical groundings of entrepreneurial SV are expressed through ongoing transparency. Whilst there are agendas, these are not necessarily hidden but instead are likely put on show for the scrutiny of markets and communities. We hope that this evidence can add more light to our still modest understanding of the ethical groundings of social entrepreneurship. (shrink)

El trabajo doméstico y de cuidados que es realizado en su gran mayoría por las mujeres es invisibilizado y no es reconocido en una sociedad que privilegia el trabajo remunerado en el espacio público realizado, en gran medida, por los hombres. Este desprecio por el cuidado del hogar y la familia ocasiona que las mujeres vayan acumulando grandes desventajas a lo largo de su vida por lo que, al llegar a la vejez, experimentan con mayor recrudecimiento las desigualdades.

We consider the first-order finite-difference expression of the commutator between d / dx and x. This is the appropriate setting in which to propose commutators and time operators for a quantum system with an arbitrary potential function and a discrete energy spectrum. The resulting commutators are identified as universal lowering and raising operators. We also find time operators which are finite-difference derivations with respect to the energy. The matrix elements of the commutator in the energy representation are analyzed, and we (...) find consistency with the equality \. We apply the theory to the particle in an infinite well and for the Harmonic oscillator as examples. (shrink)

The enthymeme is essential because it reflects what humans do when they think. It provides an effective pedagogical approach to the analysis and synthesis of ideas in the classroom. In this volume, such an approach is applied to various areas of content for the purpose of helping students prepare themselves for the challenges of modern life.

La Constitución dogmática Lumen gentium ha rescatado desde la tradición cristiana la expresión Iglesia doméstica para referirse a la familia. Dicha expresión posee en sí misma una riqueza incalculable al momento de descubrir el misterio de la esencia y misión de la familia cristiana, por lo que aporta elementos fundamentales para la elaboración de una teología de la familia. Es por este motivo que la presente investigación pretende levantar una propuesta de lectura eclesiológica de la Iglesia doméstica, a partir de (...) cuatro claves de lectura: cristológica, sacramental, pneumatológica y escatológica. The dogmatic Constitution Lumen gentium has rescued from Christian tradition, the expression Domestic Church referred to the family. Such expression possess in itself an invaluable richness considering that discovers the essence and the mission of Christian family. That´s why it contributes with fundamental matters to the elaboration of a Theology of the Family. For this reason, this research pretends to raise a proposal of ecclesiological reading of Domestic Church, based in four key reading points: Christological, sacramental, pneumatological and eschatological.

This article builds on the notion of legal tolerance and analyzes the scope of its definition. It situates the notion in the complex set of relations occurring between the major systems of society. Generally, legal tolerance, as a concept, is understood in light of the possibilities of the legal system of influencing other major systems? responses. On the other hand, tolerance is also the response of the legal system in respect to other major systems? communications. Although there is a common (...) understanding of tolerance as ?under punishing bias? in criminology or as political tolerance in political science, 1 the focus of this article is different. The central points here are, first, the analysis of legal tolerance as part of systemic communications and, second, the historicity of the transformations of the nation-state in its ability to cope with the growth of separate, distinct and partial systems of society. Tolerance seems relational and raises questions such as: ?How much can the legal system tolerate?? And also, ?Which societal topics belong to the social system's domain-matter?? These questions are relevant given that the concept of legal tolerance depends on the possibilities of a given system to steer, to direct or to influence other major systems? behavior, or to resist, respond or to address other systems, which are in its environment. The concept of legal tolerance requires an analysis of a cluster of related definitions to assess the implications of the concept. These definitions are the following: (1) The concepts that result from the historical process of structuration and that explain the emergence of social systems. (2) The definition of reflexivity and its relation with the ?second order cybernetics dilemma.? This is the place where heuristic and epistemological problems are found. Such problems result from both the problem of representation and from the ontological status of the real. This analysis will show why reflexivity is a key concept to explaining the transformations suffered by such systems. Then, legal tolerance is a newer development in respect to the idea of planning. As an alternative to hard planning, legal tolerance creates a fostering environment. Instead of a single system directing other systems, legal tolerance is relational and created collectively by the organizational national state using its (limited) power of legal creation. Legal tolerance also stems from the concerned subsystems of the society (economy, law, politics, science, along with others) by means of a variety of legislative products, public policies, alliances, and legal and other scientific communications that emerge as coordinating mechanisms among the alluded major subsystems.

Cette étude, à partir du cas colombien, présente une théorie globale novatrice du trafic des drogues, qu'elle présente comme le symptôme de la situation générale de l'homme contemporain confronté aux problèmes de la mondialisation. Elle pose ainsi le problème du trafic des drogues comme la rencontre entre des subjectivités et les productions des grands systèmes économiques, politiques et juridiques, dans une perspective sociale et anthropologique critique.

This article contrasts Saint Augustine’s role in the creation of the Church’s theological dogma to Loyola’s modern gesture of independence vis-à-vis the Church. It then traces Loyola’s method to the core that grounds Descartes’ philosophical works. This core, I claim, is derived from Descartes’ understanding and imitation of the Spiritual Exercises. The Exercises obviate the Church by making it redundant, unnecessary. From this disavowal and distancing, Loyola gives the exercitant the psychological tools to emerge from the Exercises with a strong, (...) new sense of self that with time will transform the institution from within. In Descartes’ case, the moral subject capable of responding to the question of what God wants (the product of the Exercises) is displaced by the epistemological certainty necessary to create a new “Method” to study and understand the world.

La punción lumbar es un procedimiento invasivo, no exento de riesgos y para hacerlo es necesario solicitar el consentimiento informado del paciente o de un familiar. En este trabajo se aportan elementos éticos y prácticos necesarios para la realización de un correcto consentimiento informado en los pacientes a quienes se practica este proceder. Se propone un modelo de consentimiento informado para este fin que incluye información sobre: la explicación del procedimiento, contraindicaciones, complicaciones y cuidados después del procedimiento. Se resalta que (...) el consentimiento informado para la punción lumbar, más que una exigencia institucional o legal, constituye una exigencia ética para el médico y un derecho exigible por parte de los pacientes por lo que urge instituirlo como práctica sistemática. Lumbar puncture is an invasive procedure, not exempt of risks and to do so it is necessary to request the consent of the patient or a family member. This paper provides practical and ethical elements necessary to carry out a proper informed consent in patients to whom this procedure is practiced. Proposes a model of informed consent for this purpose which includes information on: the explanation of the procedure, contraindications, complications and care after the procedure. It highlights that informed consent for lumbar puncture, rather than a legal, or institutional requirement constitutes an enforceable right by patients and an ethical requirement for medical by which urges to establish it as a systematic practice.

Graduates of doctoral programs are expected to be competent at designing and conducting research independently. Given the level of research competence needed to successfully conduct research, it is important that assessors of doctoral programs have a reliable and validated tool for measuring and tracking perceived research competence among their students and graduates. A high level of research competence is expected for all Ph.D. graduates worldwide, in addition to in all disciplines/fields. Moreover, graduates of Ph.D. programs may complete their studies in (...) one country but then obtain a research position in another country, emphasizing the need to ensure that all doctoral programs are fostering similar levels of research competence. Thus, the purpose of this study was to gather additional evidence for validity and reliability of the Research Competence scale. Specifically, we sought to extend the findings of by adapting the scale, translating it to other languages, and applying the tool with a sample of early stage researchers. Our findings provide initial evidence that the adapted PR-Comp is appropriate for use in three languages and across a variety of disciplines/programs of study. (shrink)

Children usually use the external and physical features of characters in movies or stories as a means of categorizing them quickly as being either good or bad/evil. This categorization is probably done by means of heuristics and previous experience. However, the study of this fast processing is difficult in children. In this paper, we propose a new experimental paradigm to determine how these decisions are made. We used illustrations of characters in folk tales, whose visual representations contained features that were (...) compatible or incompatible with the moral identity of the characters. Sixteen children between 8 and 10 years old participated in the experiment. We measured their electrodermal activity when they were listening to the story and looking at pictures of the characters. Results revealed a higher increase in skin conductance when the illustrations showed a moral condition that was incompatible with the actions of a character than when they showed one that was compatible. These results suggest that children make fast decisions about the moral identity of characters based on their physical features. They open up new possibilities in the study of the processing of moral decisions in children. (shrink)

Los centros penitenciarios poseen módulos educativos donde se procura dotar de enseñanza reglada a los internos para favorecer su reinserción, como se recoge en la Constitución Española de 1978 así como en los decretos de Enseñanza Secundaria para personas adultas. En este marco, se ofrece aquí una propuesta educativa para desarrollar un tema controvertido, como es el del Holocausto, en un ámbito educativo especialmente sensible a procesos educativos en situaciones de confinamiento, un aula de 4º de ESPA en un centro (...) penitenciario, a través del conocimiento de las responsabilidades criminales consideradas en los Juicios de Núremberg. Utilizando la representación dramática como recurso didáctico, ya que los internos tendrían que reproducir los distintos roles de los participantes en los juicios, se pretende, en las diferentes sesiones en las que está estructurada esta propuesta, tratar de las responsabilidades morales, entender la necesaria existencia de unas instituciones fuertes con códigos de convivencia adecuados y desarrollar la empatía con las víctimas del régimen nazi, con el objetivo de que sean desarrollados valores cívicos entre los internos.
