The aim of this article is to argue that a temporal asymmetry may be established within the framework of quantum field theory, independently of any violation of CP, and thereby T, in weak interactions, and independently of the property of time reversal invariance that its dynamical equations instantiate. Particularly, I shall argue that the temporal asymmetry can be stemmed from assessing the links between the proper group of symmetries of the theory and the ontology of the theory: arguments applied to (...) establish which elements and magnitudes remain invariants under group transformations can also be used to establish a temporal asymmetry.

There is a widely extended viewpoint about physical possibility, what we will call Standard Approach, which holds that the physically possible is delimited by the nomological structure of physical theories: to be physically possible is to be in accordance with the physical laws, to be physically impossible is to be prohibited by physical laws and to be physically necessary is to be demanded by the physical laws. However, it is possible to show that this approach is too relaxed and permissive (...) when it comes to collecting and systematizing many of the modal intuitions present in the physical community. In this work we will argue, on the one hand, that the notion of physical possibility is more complex and richer than suggested by the standard approach and, on the other hand, that it is necessary to add some extra elements to the characterization of physical possibility in order to that it is adequate in scientific contexts.

El propósito central de este artículo consiste en realizar un análisis de la pandemia actual, intentando situar estratos básicos del fenómeno, y particularmente el modo como se estructura su mundo y los vínculos de coexistencia entre los individuos, tomando como hilo conductor un elemento que la analítica existencial heideggeriana destaca como característico del modo de apertura del hombre al mundo: el temple anímico o la disposición afectiva. Para situar este elemento y buscar una orientación para nuestra indagación, analizaremos el relato (...) de Tucídides acerca de la peste que asoló a Atenas a finales del siglo V a. C. Partiendo de las indicaciones que extraeremos de Tucídides nos encaminaremos hacia el campo de la analítica existencial para descubrir a partir de su enfoque el modo como se definen las relaciones mundanas en conexión con el temple anímico del miedo. Nos interesa mostrar cómo este temple anímico motiva una especial transformación del sentido del virus responsable de la pandemia actual, transformación que nos lleva a considerar su carácter mutualista, lo cual remitirá en última instancia y de manera retroactiva a una mejor determinación del modo de ser de la existencia humana, como esencialmente vinculada al otro, como co-existencia.

There is an argument by M. Dummett about the relative priority of language as a social phenomenon. The first step is to explain how the speaker and the hearer have to know the same language, ceteris paribus. The second step is to show how the speaker's idiosyncratic beliefs depend on his knowledge of common language; the last step is to appeal to Quine's principle of translation between languages in order to have a language at all.

Pathological Altruism presents a number of new, thought-provoking theses that explore a range of hurtful effects of altruism and empathy.

In this note, my aim is to point out a phenomenon that has not received much attention; a phenomenon that, in my opinion, should not be overlooked in the professional practice of philosophy, especially within feminist efforts for social justice. I am referring to the way in which being a non-native speaker of English interacts with the practice of philosophy.1 There is evidence that non-native speakers are often perceived in prejudiced ways. Such prejudiced perception causes harm and, more importantly, constitutes (...) wrongdoing. As in other cases of prejudiced perception and biased behavior, it would be pretentious and misguided to expect philosophers and the philosophy profession to be free from this vice. There are good reasons to think that this prejudiced perception is bad not only for the persons who are perceived in such a way, but also for the profession, for it might make us miss important things that could improve philosophy in general. I claim we should be more sensitive to this phenomenon, both out of concern for justice, and for the sake of doing better philosophy. (shrink)

Objective: To describe the professional values of the nurse lectures according to 241 nursing students, who participated voluntarily, in three different universities of Bogotá. Methodology: This is a quantitative, descriptive cross-sectional study that applied the Nurses Professional Values Scale—permission secured—Spanish; three dimensions of values were applied: ethics, commitment, and professional knowledge. Ethical consideration: Project had ethical review and approval from an ethics committee and participants were given information sheets to read before they agreed to participate in the project. Findings: It (...) was concluded that nursing students, in general, do perceive these values in their professors, and they give priority to the dimension of ethics, followed by the knowledge dimension, and finally, commitment. Discussion: It is evident that professional values are transmitted by professors and students place importance to such values. Values related to the other’s care are paramount in nursing training in Colombia as well as in other countries. Conclusion: It was found that participating students observed professors directly in relation to values focused on direct patient care, respect for privacy, respect for life, while matters related to professional improvement, participation in unions were not actually analyzed may be due to poor promotion activities and unions during undergraduate studies. The results obtained are primary approach to the study of values related to nursing, a topic which needs to be researched, something vital to all the country offering nursing training programs.

Después de una visión general del Gorgias de Platón, se hace una presentación del realismodel personaje Calicles y la respuesta de Sócrates, así como de las tesis centrales sobre la justicia en el texto. Posteriormente se sintetizan algunas de los elementos nucleares de la ética de la investigación que compete a los comités de regulación de los estudios clínicos, poniendo énfasis en los vacíos que dejan ver desde la perspectiva filosófica, a la luz del propio texto platónico, y los aportes (...) que este último podría ofrecer, sobre todo desde perspectiva de la prudencia y la equidad griegas.After an overview of Plato’s Gorgias a presentation of Callicles’ realism and the response of Socrates is made, as well as the main theses on justice in the text. Then some of the main elements of research ethics concerning regulation committees of clinical studies is synthesized, pointing out the gaps that appear there from a philosophical perspective, in the light of the platonic text and the contributions that this text can make, in particular from the perspective of Greek prudence and equity.

This dissertation studies the relationship between divine providence and human freedom in Hegel's thought. The view taken in this study is that an understanding of this relationship in the philosophy of Hegel hopefully will shed significant light on the contemporary dialogue that considers religious faith not as an alienating human experience, but rather, as fundamental for full human liberation and self-realization. ;The underlying hypothesis of this study is that the Absolute Spirit in Hegel's philosophy, not only is the providential trinitarian (...) God of the Christian religion; but it is also thereby what constitutes precisely the ultimate foundation and necessary condition of possibility for authentic human freedom. ;In line with this, for Hegel, on the one hand, authentic human freedom necessarily entails man's creative commitment to the revolutionary progressive process of human liberation from oppression that is taking place in man's history under divine providence; and on the other hand, the nature of divine providence coincides with the internal logic of the reconciling love of the trinitarian God. Hence, our study attempts to show that, according to Hegel, world history is constituted by a progressive process of liberating reconciliation among men, that takes place in the very process wherein men reconcile themselves with the trinitarian love of God. This reconciliation of man with the trinitarian love of God specifically entails man's "paschal" elevation to the eternal death and resurrection of God that takes place in the death and resurrection of Jesus Christ. ;While our study concentrates especially on Hegel's Lectures on the Philosophy of Religion and on the Introduction to his Lectures on the Philosophy of History, its main ideas are elucidated by taking into consideration also the works of Hegel's mature system since and including the Phenomenology of Spirit.

El núcleo central del artículo gira en torno al relativismo respecto del conocimiento científico. El autor quiere defender la posibilidad del conocimiento objetivo, sin renunciar por ello a la idea de una perspectiva humana. De este modo se enfrenta a quienes conciben la objetividad como el abandono de cualquier perspectiva humana. En este contexto el escepticismo es valioso, al cuestionar las apariencias ligadas a una perspectiva más subjetiva y fomentar la adopción de una perspectiva objetiva, en la que consiste el (...) conocimiento científico.

A filosofia alemã do século XIX posterior a Hegel está bastante estudada em três direções. A primeira, que surge da luta entre hegelianos de esquerda e direita, acaba por conduzir ao materialismo e ao marxismo; a segunda, que se expressa na vertente irracionalista e anti-sistemática, passa por Schopenhauer, Kierkegaard e Nietzsche; a terceira é constituída pelo neo-kantismo e suas derivações, cuja versão oficial teria suas raízes fincadas pelo famoso discurso inaugural de Zeller e pelo livro de Otto Liebmann, que deram (...) o impulso ao movimento “Zurück zu Kant”. Em tal visão de conjunto, o grande ausente é um movimento contínuo, ainda quando irregular e multifacetado, que terminará conduzindo à filosofia contemporânea. Este movimento tem em Trendelenburg uma figura chave. É com suas “Investigações Lógicas” que se inicia a reformulação das relações entre filosofia e ciência e, neste sentido, o verdadeiro retorno a Kant. O fato de sua obra principal ter exatamente o mesmo nome que a coleção de ensaios temáticos de Frege, a obra de ruptura de Husserl e as dissertações de doutorado de Cohen, Dilthey e Brentano significa algo mais que curiosas coincidências. “Zurück zu Kant” (Adolf Trendelenburg the overcoming of idealism and the roots of contemporary philosophy)Considering history of philosophy as a whole, the two main traditions of thought from the 20th century (analytic and phenomenological-hermeneutic) can be regarded as being variants of one same fundamental turn. This systematic relation is connected to a common historical root. To highlight it implies to review the ideas that are deeply in the basis of the historiography of the German thought in the 19th century. Beyond names, problems and theses that may appear to have at first sight no relationship whatsoever, we can notice a continuous unitary development that has not yet received all the attention it deserves. In this movement, Adolf Trendelenburg stands out, once the beginners of both the abovementioned traditions and of neokantianism (Frege, Brentano, Dilthey and Cohen) received a decisive impulse from his reflections.

La crisis de la ciencia europea es un tema presente en la filosofia alemana luego del fracaso del idealismo alemán. Esa crisis encuentra una expresión decisiva en la filosofia de Hermann Lotze, autor extremamente influyente en la segunda mitad del siglo XIX y que actúa como referencia e inspiración para las reflexiones husserlianas de la década de 1930.

Texto tardío publicado con motivo de una exposición de obras de Camilla Adami, “Tête-à-tête” de Jacques Derrida constituye un punto de convergencia temático alrededor de la cuestión del animal. En el presente artículo, con base en una traducción propia, que constituye la primera versión en español de esta obra, proponemos una lectura siguiendo las conjugaciones del pathos que se dan en él, identificaremos los motivos del ver y el tocar como claves para entender la postura derridiana en torno a la (...) cuestión del animal. Esta última coloca las pasiones en el corazón de una ética no antropocentrista, capaz de tomar en cuenta al resto de los animales, lejos de toda perspectiva racionalista y logocéntrica. (shrink)

Drawing on insights from scholarship on contentious action frames, this article examines the framing of demands for social justice for migrant farmworkers in Spain, Italy and Canada during the COVID-19 pandemic. We focus particularly on how activists in each country aligned their action frames with prevalent public discourses on the essential contribution migrants make to agricultural production, the need to guarantee “health for all,” and “increased vulnerability” of migrants’ lives during the global health crisis. Using these diagnostic frames, activists in (...) the three countries called for secure legal status for all migrants. Drawing on the literature on contentious action frames, we then analyze if action frames advanced by activists during the COVID-19 pandemic “resonated” with the understanding of these issues by policymakers. We challenge an approach to understanding resonance in binary terms as either present or absent. Instead, we introduce the notion of “ambivalent resonance” to draw attention to the fact that some frames are accepted only partially or only by some policymakers but not the others, as was the case in the three countries under study. We then situate this ambivalent resonance in the context of immigration priorities and recent trends in immigration policy development in these three countries and suggest that activists can build on ambivalences to advance migrant rights to status.

This paper aims to improve knowledge about the main factors influencing firm environmental commitment, by examining empirically the relationship between public support for R&D for small and medium enterprises (SMEs) and their investment in environmental protection. The empirical analysis was developed using a sample of 1594 Spanish firms, and a binary logistic regression to evaluate the existence of dependency relationships between the analyzed variables. The results show that those companies receiving direct funding from local public entities and those collaborating with (...) research centers and universities, invest more in environmental actions to protect the natural ecosystem. The paper contributes to the academic literature by analyzing the main factors that influence the SMEs environmental commitment. Moreover, showing practitioners and policy makers the effectiveness of different types of financial support depending on the origin of the funds and the form of action taken; showing managers the advantages of collaborating with public administrations, as well as with other research organizations, to obtain better ECSR results.

Este artigo examina o papel desempenhado por Schafick Jorge Handal no processo de conversão política do Frente Farabundo Martí para a Libertação Nacional, no período de pós-guerra. Aqui são analisados os principais debates vinculados à redefinição política e ideológica do FMLN, à liderança do partido e à democracia interna. Este processo foi marcado por fortes disputas entre as lideranças das antigas organizações político-militares que compunham a FMLN. Handal foi o principal protagonista dessas lutas, nas quais que ganhou poder e reconhecimento (...) interno. No entanto, ele morreu subitamente em 2006, quando o processo de ‘unificação’ estava avançado, mas não consolidado. Porém, na memória oficial do partido, Handal tornou-se o principal referente identitario do FMLN de pós-guerra, apesar de que seu triunfo traduziu-se na saída de três das cinco organizações que integravam o FMLN.

La création de « puces synaptiques » qui seraient dotées d’une certaine plasticité ouvre-t-elle la voie à une intelligence artificielle vraiment « intelligente », même si de façon différente des êtres humains? Ou la nature des avancées de ce type, d’une plasticité à des années lumières de celle du cerveau humain, nous contraignent-elles à beaucoup plus de scepticisme? Pour la philosophe Catherine Malabou, l’essentiel est de permettre aux deux intelligences, naturelle et artificielle, de s’enrichir l’une l’autre. De ne jamais fermer (...) la voie des possibles, que ce soit par des réflexions philosophiques, des fictions ou des expérimentations. (shrink)

En la primera sección, hemos desarrollado ejemplos y hecho observaciones a modo de análisis para probar por qué las narrativas son importantes para nuestras emociones secundarias. En la segunda sección, hemos examinado (...) por qué la confianza puede ser considerara como una emoción secundaria así como establecer un criterio para identificarla como tal_. _En la tercera sección, presentamos una de las funciones de la confianza, el intercambio de conocimiento entre agentes, cuando se comparte conocimiento en un proceso epistémico con otros. Hemos comprobado que la construcción de la relación entre sujetos y objetos se produce mayoritariamente gracias a la confianza. Una emoción secundaria que representa lazos afectivos entre sujetos para acceder a una emoción primaria. (shrink)

The elastic and radiative π + p scattering are studied in the framework of an effective Lagrangian model for the Δ ++ resonance and its interactions. The finite width effects of this spin-3/2 resonance are introduced in the scattering amplitudes through a complex mass scheme to respect electromagnetic gauge invariance. The resonant pole (Δ ++) and background contributions (ρ 0, σ, Δ, and neutron states) are separated according to the principles of the analytic S-matrix theory. The mass and width parameters (...) of the Δ ++ obtained from a fit to experimental data on the total cross section are in agreement with the results of a model-independent analysis based on the analytic S-matrix approach. The magnetic dipole moment determined from the radiative π + p scattering is $\mu _{\Delta ^{ + + } } = (6.14 \pm 0.51)$ nuclear magnetons. (shrink)
