In this paper we characterize the join irreducible elements of the free algebras on n free generators in the subvarieties of the variety V0 of pseudocomplemented De Morgan algebras satisfying the identity xx′* = ′*.

Los análisis tomados de diferentes fuentes expuestas en las referencias bibliográficas permiten inferir que la migración es un fenómeno natural del ser humano, inevitable e incluso necesario. Según la OIM una de cada siete personas en el mundo es migrante internacional, es decir que, para finales del 2018 existían en el mundo 258 millones de personas que por diversas razones decidieron trasladarse de sus lugares de origen. En los últimos años se ha convertido en uno de los países que más (...) recibe ciudadanos venezolanos, no solamente por la cercanía y la amplía frontera que se comparte, también porque durante muchos años Venezuela recibió colombianos que buscaban mejores condiciones y más seguridad. En estos términos Colombia había tenido una deuda histórica con Venezuela, la cual ha saldado a la fecha siendo el país que más ha recibido migrantes venezolanos. (shrink)

El presente artículo pretende analizar el método que utiliza Norberto Bobbio para investigar sus objetos de estudio centrales, a saber: el derecho y la política. Se argumenta que el método de investigación propuesto por Bobbio es el de la reconstrucción. Además, se propone que para su despliegue su acude a la delimitación conceptual y la reconstrucción histórica. Un hallazgo importante del artículo muestra que es la perspectiva de la filosofía como concepción del mundo, elaborada por Bobbio, entre los años 40 (...) y 50 del siglo pasado permite la concreción del metido y las herramientas para entender la política y el derecho. Para la filosofía, en tanto concepción del mundo, Bobbio tomará elementos importantes de la tradición de la filosofía analítica, por una parte; por otra parte, de las enseñanzas de algunos filósofos, que, a través de los siglos, se han consolidado como clásicos. La reconstrucción como método de investigación mostrará que los objetos de estudio tales como el derecho y la política se comprenden partiendo de un cuidadoso y riguroso análisis de los conceptos fundamentales que los componen y del examen de las teorías esenciales de los filósofos clásicos del pensamiento occidental en el terreno político y jurídico. Para tratar estos asuntos, el presente artículo se dividirá en las siguientes partes: en un primer momento, se analiza la concepción de filosofía de Bobbio. En segundo lugar, se examina la idea de que la filosofía como método de investigación se debe entender como una dinámica de reconstrucción. Por último, el artículo propone que el desarrollo de la filosofía como método se efectúa a través de la delimitación y el análisis conceptual y a través de la reconstrucción histórica de los clásicos del pensamiento occidental.

This introduction presents the field of experimental moral and political philosophy as a confluence between different disciplines and research traditions. This chapter begins by highlighting the importance of several historical currents and presenting the scope and nature of a diverse and rich research agenda within the contours of a broad research area. The development of behavioural economics, the revisiting of John Rawls’ psychological assumptions in his Theory of Justice, the framework of bounded ethicality, the rebirth of philosophical naturalism, and the (...) burgeoning movement of experimental philosophy are given credit in the convergence leading to the current state of the field. This chapter ends by presenting a few active subfields that, in addition to their social relevance, may strengthen the hybrid enterprise of experimental moral and political philosophy by producing new and interesting results in the coming years.

The work of Anthony J. Steinbock on emotions―particularly moral emotions―and on religious experience is closely related to a methodological claim. This claim is that the concepts of “experience” and “manifestation” should be understood in a broader manner than that of classical phenomenology, particularly Edmund Husserl’s phenomenology. In this paper, I examine the way in which Steinbock understands and conceptualizes the kind of givenness to which he refers with the notion of “vertical experience”. I focus on his claim that vertical experiences (...) are irreducible to the kind of experiences that can be described in terms of what he calls “provocation”, “presentation” and the “noesis-noema structure”. Even though I make a criticism of his assertion that the latter implies that they should not be understood as forms of givenness founded on the above-mentioned structure, I agree with some major implications that he draws from them. In the last part of the paper, I discuss his suggestion that the Husserlian conceptualization of emotional givenness should be revised to set forward their structure in terms of what he calls “evocation” and try to give additional reasons, drawn from Husserl himself, to support this claim. The paper comes concludes by stressing the relevance of Steinbock’s analyses concerning what he calls “idolatry”. I argue that his analyses of attitudes that negate the vertical dimension of experience have far reaching implications that go beyond the field of philosophy of religion and open new, promising paths for phenomenological research on social and moral problems.

Sustainable Public Food Procurement (SPFP) is gaining recognition for its potential to improve the sustainability of food systems and promote healthier diets. However, SPFP faces various challenges, including coordination issues, actor dynamics, infrastructure limitations, unsustainable habits, and institutional resistance, among others. Drawing upon insights from the Multi-Level Perspective (MLP) on socio-technical transitions and the X-curve model on transition dynamics, this study investigates the role of transition intermediaries in facilitating SPFP-induced transformations in food systems. Focusing on four case studies in Spain, (...) we identify common barriers encountered in SPFP and analyse how distinct types of transition intermediaries contribute individually and collectively to address these challenges. Additionally, we explore how intermediary networks evolve throughout different phases of the transition process. Our findings reveal that SPFP barriers are systemic and interconnected, emphasizing the necessity of collective intermediation to overcome these obstacles. Furthermore, our results reveal how collective intermediation is orchestrated by pivotal intermediaries who mobilize diverse transition intermediaries, shaping multiple transition pathways. These intermediaries operate at both food system regimes and niches, challenging the conventional notion that transformative change can only originate from niche efforts. Lastly, we highlight the dynamic and flexible nature of intermediation in SPFP transitions, underscoring the importance of adaptability in strategies as these transitions evolve over time. Practical implications include the need for context-specific, adaptive approaches and strategies that leverage intermediary diversity. This research offers insights for policymakers, practitioners, and scholars into SPFP and broader transitions towards food systems transformation, fostering a more comprehensive understanding of these transition processes.

Most governments worldwide recognize marriage as the union only of man and woman. Especially in Europe and North America, however, there is growing support for legalization of same-sex marriages. The impending shift in marriage policy posits the supposed insignificance of sexual difference. There is thus a need for comprehensive reflection on the essential substance of sexual differences, and on the legal and social relevance of sexual complementarity. Defendersof traditional marriage must be prepared to offer reasons why society must continue to (...) recognize sexual difference as a fundamental attribute of marriage,argued in terms that carry authority and meaning in today’s post-Christian ethos.

Resumen En este artículo reflexiono sobre la posibilidad de conceptualizar los derechos humanos como hechos institucionales, lo cual permite enmarcarlos en una perspectiva más amplia que las meramente jurídicas y morales. La propuesta se basa en la ontología social de John Searle, aunque intento replantearla desde la fenomenología de Edmund Husserl y la teoría de los actos sociales de Adolf Reinach. En la parte final introduzco problemáticas relacionadas con el papel de los Estados nacionales en la institucionalización de los derechos (...) humanos. Para ello me apoyo en la idea de Hannah Arendt de que los derechos humanos presuponen el derecho a tener derechos y la pongo en relación con observaciones más recientes de especialistas.In this paper I reflect on the possibility of conceptualizing human rights as institutional facts. This aims to frame them in a broader perspective than a merely legal or moral one. The proposal is based on John Searle’s social ontology, but I attempt to think it over with the support of Edmund Husserl’s phenomenology and Adolf Reinach’s theory of social acts. In the final part I set forward problems related with the role of national States in institutionalizing human rights. To elaborate this point, I draw on Hannah Arendt’s idea that human rights presuppose the right to have rights and relate it with more recent observations of experts. (shrink)

Há uma filosofia da diferença que precisa ser mais considerada nos nossos tempos, visto que se opõe à tradição filosófica identitária dos pré-socráticos à atualidade, que se apegou obstinadamente à ideia de identidade, que vislumbra o real, somente através da referência ao idêntico. Nessa perspectiva, os anseios e peculiaridades dos mais diversos movimentos sociais precisam ser ouvidos de modo mais efetivo pela filosofia e pela ciência. Mesmo nas ciências exatas, a teoria não é eterna, quanto mais nas sociais aplicadas, como (...) é na ciência da informação, e consequentemente, na organização do conhecimento. Posto isto, este trabalho tem como objetivo inter-relacionar alguns aspectos históricos da epistemologia geral com as epistemologias feministas, destacando-se a corrente pós-estruturalista. E assim, compreendermos alguns dos seus desdobramentos na organização do conhecimento, a fim de percebermos se ela está disposta a incorporar novas práticas, a partir de reinvindicações de movimentos, como o feminista. Constatamos que além de toda historicidade das relações de poder que tem raízes profundas e muito antigas, há nos dias hodiernos um grupo despreocupado em ratificar novas práticas mais humanizadas e coerentes às várias esferas, dentre as quais está a organização do conhecimento, por questões não só políticas, mas econômicas.

En este artículo se abordan aspectos centrales del pensamiento de Luis Villoro que se desprenden de la relación crítica que mantuvo con la fenomenología trascendental de Edmund Husserl. Algunos de ellos son las preguntas sobre el sentido que tenga la reflexión filosófica en los contextos vitales y sociales concretos en los que se lleva a cabo, así como sobre la tarea de la filosofía misma, los temas sobre los que no puede dejar de hablar y el tipo de conocimiento al (...) que debe aspirar. En la parte final se sugiere que las perspectivas que se abren con el estudio comparativo de estos dos pensadores son importantes para reivindicar la tarea crítica de la filosofía respecto de la realidad en la que se cultiva y se despliega.

RESUMEN Se analiza la relación entre las memorias inscritas en el cuerpo, el trauma y los recursos corporizados subjetivos y colectivos con los que cuentan las mujeres víctimas de violencia para reconstruir y resignificarse como personas dignas de credibilidad y agentes de cambio. Se refieren casos específicos de violencia sexual en Colombia y se expone la importancia de la creación de comunidades de confianza que propicien espaclos para la narración y escucha de los testimonlos de víctimas, la tramitación de conflictos (...) y nuevas vías de afrontamiento, a partir de los recursos que brinda la reinvención de hábitos corporizados en el arte. ABSTRACT The article analyzes the relation among memories inscribed in the body, trauma, and the subjective and collective embodied resources available to women victims of violence in order to reconstruct and resignify themselves as persons worthy of credibility and as agents of change. It discusses specific cases of sexual violence in Colombia and the importance of creating communities of trust that foster spaces for narrating and listening to the testimonies of victims, as well as for handling conflicts and exploring new ways of coping, on the basis of the resources provided by the reinvention of habits embodied in art.

Bernard Williams proposed his relativism of distance based on the recognition “that others are at varying distances from us”. Recent work in moral psychology and experimental philosophy highlights the prevalence of folk relativism in relation to spatial and temporal distance. However, Williams’ relativism of distance as well as recent empirical findings which seem to support some of Williams’ main ideas on this issue have received scant attention. In this article, we would like to focus on the phenomenon of moral relativism (...) regarding spatiotemporal distance as an entry point to the nature of folk moral relativism and the methodology of meta-ethics. To do so, we first introduce Williams’ relativism of distance. Then we compare Williams’ approach on this matter to recent experimental approaches on folk relativism. On this score the main result is that Williams’ proposal is consistent with several well-established insights on the experimental study of folk relativism. Williams’ relativism of distance is not only empirically plausible, but it is also of relevance for shaping the methodology of an empirically informed meta-ethics. We close this paper by stressing this methodological contribution. (shrink)

This work will examine the main issues generated in the discussion about social justice, freedom and equality from a Marxist and egalitarian liberalism perspective, which would require an answer if the search for a good society continues. Since the world’s economic, social, political and cultural situation has changed in the last decades, nowadays the necessary ethic-political foundations for a fair and free social order must be discussed. The problem is to clarify, in the light of political philosophy and human sciences, (...) the proposals made about such social order and for the current moment, and from the socialist and egalitarian liberal theories with thinkers such as Marx, Cohen and Roemer, for the first, and Rawls, Dworkin Nagel and Sen, for the second, among others. The purpose of this work is mainly didactic and deals with a description of situations such as poverty, exclusion and social inequality that the world lives in. It also deals with the authors’ proposals about such topics, analyzing if there is incompatibility between the capitalist institutions and the socialist project for the achievement of these ideals/values that give origin to the title.

The text brings a reflection on pain and memory relationship from Colombian sculptor Doris Salcedos’s work Shibboleth, whose background is the current Colombian armed conflict. More precisely, it emphasizes on the relevance of memory in a community’s authentic historical configuration. Or, in Beuys’ words, showing the wounds is highly important when trying to find cure and healing for a serious ill society, bathed in a bloody conflict between those born there, a land that, like it or not, it’s found to (...) be common for all of us.

El presente artículo pretende reflexionar en torno a la problemática de la potencial sustitución o remplazo del ser humano por parte de la tecnología de la automatización. El debate, tan antiguo como la modernidad, ha sufrido en los últimos tres años un impulso sorprendente debido a la aparición en la esfera pública de los algoritmos probabilísticos productores de textos o imágenes: las llamadas IA generativas. En un contexto de discursos sensacionalistas arrastrados por un alarmismo o utopismo fomentado por las estrategias (...) comerciales de las «big tech», el presente trabajo se propone pensar críticamente los términos del problema, ahondando en lo que hay ontológica y políticamente en juego en esta supuesta sustitución. Este artículo propone que el problema puede ser adecuadamente reenfocado si se entiende que en el origen del sujeto moderno no yace ninguna cualidad distintivamente humana, sino el vacío de un movimiento tropológico de (auto)sustracción siempre en marcha.

This article shows the close relationship that exists between two fundamental concepts in the theological doctrine of Origen of Alexandria: “fullness” and“participation”. These two concepts have been the subject of many earlier studies. However, they treated the topic in a more restricted sense, exploring very specific aspects of Origenian theology. The originality of this study lies in demonstrating how both concepts recur frequently in his theological thinking, give it a framework and hold his thought together. They consequently systematize and make (...) possible a perfect synthesis of all his thinking. (shrink)

En el terreno de la moral, el contraste entre lo ¿que el filósofo Wilfrid Sellars denominó «la ¿imagen manifiesta» y la «imagen científica» es enorme y tiene unas consecuencias prácticas ineludibles.

BackgroundThe effect of orgasm on the development and shaping of partner preferences may involve a catalysis of the neurochemical mechanisms of bonding. Therefore, understanding such process is relevant for neuroscience and psychology.MethodsA systematic review was carried out using the terms Orgasm, Sexual Reward, Partner Preference, Pair Bonding, Brain, Learning, Sex, Copulation.ResultsIn humans, concentrations of arousing neurotransmitters and potential bonding neurotransmitters increase during orgasm in the cerebrospinal fluid and the bloodstream. Similarly, studies in animals indicate that those neurotransmitters and others modulate (...) the appetitive and consummatory phases of sexual behavior and reward. This suggests a link between the experience of orgasm/sexual reward and the neurochemical mechanisms of pair bonding. Orgasm/reward functions as an unconditioned stimulus.

En un contexto de transformaciones profundas en la sociedad boliviana, el autor plantea que más que una nueva teoría de la sociedad boliviana se requiere desarrollar otra mirada. En esta dirección, el presente artículo busca plantear un esquema renovado sobre las referencias desde las cuales deben encuadrar el debate los bolivianos y bolivianas. El texto aborda la construcción de matrices culturales, explicitando la moderna y la andina, y conecta matriz cultural con institucionalidad, para proponer una institucionalidad andina.

In this paper we exhibit a non-finitely based, finitely generated quasi-variety of De Morgan algebras and determine the bottom of the lattices of sub-quasi-varieties of Kleene and De Morgan algebras.

In this paper we describe the Priestley space of a quasi-Stone algebra and use it to show that the class of finite quasi-Stone algebras has the amalgamation property. We also describe the Priestley space of the free quasi-Stone algebra over a finite set.

Latina immigrant women who work as nannies or housekeepers and reside in Los Angeles while their children remain in their countries of origin constitute one variation in the organizational arrangements of motherhood. The authors call this arrangement “transnational motherhood.” On the basis of a survey, in-depth interviews, and ethnographic materials gathered in Los Angeles, they examine how Latina immigrant domestic workers transform the meanings of motherhood to accommodate these spatial and temporal separations. The article examines the emergent meanings of motherhood (...) and alternative child-rearing arrangements. It also discusses how the women view motherhood in relation to their employment, as well as their strategies for selectively developing emotional ties with their employers' children and for creating new rhetorics of mothering standards on the basis of what they view in their employers' homes.

In this paper I examine the structure of hope and trust from a phenomenological perspective in order to analyze the kinds of beliefs, valuings, and practical dispositions involved in them. I claim that there are some basic aspects of the social world that would be inconceivable without the feeling components of these attitudes. However, since these attitudes are only rational in as far as they involve rational beliefs, valuings, and practical assumptions, a complex theory of reason that deals with these (...) three domains is necessary to understand what is at stake in them. Accordingly, I attempt to sketch central aspects of the Husserlian pluralistic conception of reason and highlight the way in which, when they are rational, the valuings involved both in hope and trust open new possibilities to act in rational or meaningful ways. This leads me to stress the role of the feelings involved in these attitudes, for I claim that such valuings or axiological assessments are based on them. I argue that hope allows us to act rationally in the face of uncertainty and what lies beyond our control. In the final part I elaborate on the idea that trust is founded on hope. I examine what happens when hope is expressed and how being found trustworthy by others implies being capable of establishing all kinds of social relationships, including relationships in which the trusted one is dominated. This opens the possibility of raising ethical questions concerning trusting and responding to the trust of others. (shrink)

El presente texto es una indagación del concepto de utopía propuesto por el filósofo colombiano Darío Botero Uribe, en relación con el concepto de disenso expuesto por el filósofo francés Jacques Ranciére. El pensamiento político de los dos autores toma como centro de las transformaciones políticas el movimiento individual ético en forma de acción política en vía de trasformación de diferentes formas de dominación presentes en las sociedades actuales. La intención entonces se centra en la estética como disputa de la (...) reformulación del campo social, económico y político, que coloca lo político en permanente contingencia y devenir, por lo que nunca existe un proyecto político último o ‘verdadero’ esencial, a manera de los grandes movimientos del siglo XX, sino que en eco de la propuesta foucaultiana los dos autores sostienen una forma de estética de la existencia en cuanto acción política.

Instead of the usual apologetic treatment found in legal doctrine, linked to the determinacy, immutability or predictability of norms, this book treats legal certainty innovatively, holistically and in depth. Using a method at once analytical and functional, Professor Ávila examines the structural elements of legal certainty, from its definition and foundations to its various dimensions, normative forces and efficacies, citing a wealth of examples from case law to support each of the theses defended. No subject is more important and topical (...) than legal certainty. Problems relating to lack of understanding, instability and unpredictability of law intensify day by day everywhere, in civil law and common law countries alike. Normative sources are increasingly diverse in origin and multiple in nature. They change constantly, and present increasingly frequent problems of ambiguity and vagueness that significantly hinder their comprehension. This state of affairs, which to a greater or lesser extent is true of any legal order, justifies a return to the subject of legal certainty. In this book, essential questions are answered such as: Legal certainty in what sense? Certainty of what, for whom, in whose vision and by whom? When, to what extent, and to what end? “ it is probably the most comprehensive and systematic study ever produced on this subject using the analytical method.”. (shrink)
