In 1971, Chicano activist Armando Réndon began to chart new directions for Chicana/o politics that move away from a narrow emphasis on cultural and ethnic nationalism. He argues that urban Chicana/o neighborhoods ought develop community-based organizations to provide support services for residents and to advocate local concerns to elected officials. In the first part of this essay, I reconstruct Réndon's concept of a 'barrio union' as an example of participatory democracy. I situate his concept of neighborhood democracy within Mexican (...) American and Progressive movement history, and then highlight contemporary experiments with this model that are particularly successful in transforming traditionally marginalized individuals into active democratic participants. I then suggest that the barrio union is a repository of cultural, ethical, and political ideals that might be used by progressive Chicana/o activists to challenge the meaning of dominant institutions and political traditions within the United States, particularly the ways in which we conceive of race and American citizenship.

The beginning of university life can be a stressful event for students. The close social relationships that they can experience can have positive effects on their well-being. The objective of this paper is to estimate the effect of perceived social support on the changes of the hedonic and eudaimonic well-being of Chilean university students during the transition from the first to the second academic year. Overall, 205 students participated with an average age of 19.14 years, evaluated during their first academic (...) year and the succeeding one. For the evaluation of perceived social support, the Spanish version of the Perceived Social Support Questionnaire “MSPSS” was used, and PERMA-profiler was used to measure hedonic and eudaimonic well-being. Changes through the time of hedonic well-being and social support and the correlations between the variables were analyzed. Changes in the perception of social support were analyzed according to four categories of hedonic well-being. The prediction of social support for eudaimonic well-being was evaluated. Results indicated that the perception of students’ social support did not change over time. Statistically significant differences were found in hedonic well-being scores in the two measurements, being significantly higher in the first measurement than in the second one. More than 50% of the participants presented a positive balance of affections. The perception of social support is associated with the two types of well-being. Students who had a high balance of affections had a greater perception of general social support than the groups of positive evolution of affections and a low balance of affections. In the case of the friends and family support dimensions, the perception in the high-balance group of affections concerning the low-scale group is greater. Improving the perception of social support increases the eudaimonic well-being of university students. The perception of support that students had during the beginning of their university life benefits their general well-being, which contributes to their mental health. (shrink)

Un examen panorámico de la obra literaria de Pedro Gómez Valderrama sugiere una esporádica alusión al arte visual. Sin embargo, una revisión detenida de la misma permite ver que el escritor planteó en sus textos una auténtica mirada sobre el arte a partir de la relación historia-literatura. Este artículo presenta un análisis de uno de sus cuentos en el que se puede identificar claramente el tema artístico a través del uso de la ecfrasis literaria. Así, se hace referencia a la (...) pintura de Mazepa y a cómo el escritor juega con la ambigüedad mítica del personaje real, aprovechando el aspecto histórico, el carácter romántico de la obra pictórica y la construcción literaria.

A major inspiration for the leaders of both the American Revolution and the French Revolution, Jean-Jacques Rousseau continues to be a widely read and referenced philosopher, novelist, and political theorist. This title devotes two chapters to Rousseaus eventful life, another to a detailed discussion of his 1762 work "The Social Contract," and a fourth to the impact that he had on the Founding Fathers of the United States. While "The Social Contract" is explored in the greatest depth, other of his (...) worksincluding his passionately argued Discourses, wildly popular novels, successful opera, and genre-shaping "Confessions"are also covered.

This article aims to highlight the theoretical and philosophical debate on hospitality underlining the normative elements of framing migrants and refugees as individual agents in the light of hospitality theory and migration governance. It argued the critiques of the neo-Kantian hospitality approach and the EU welcome culture with regard to refugees in the EU from a philosophical perspective. The “No human being is illegal” motto is proposed to be conceived as a principle of the EU Charter of Fundamental Rights. The (...) cosmopolitan right to visit and the universal right to reside were discussed in the context of human rights and co-responsibility. Linking the hospitality approach with migration governance enables the reconstruction of reception policies and practices, diversification of non-state actors that engage in migration governance mechanism, and polarization of political initiatives (e.g., politics of allocation and dispersal, readmission negotiations, convergence/divergence of priorities and strategic interests). The research findings highlight that the EU adopted a neo-Kantian hospitality approach that combines both “co-responsibility” and “vertical/heterarchical relations.” The EU’s “New Pact on Migration and Asylum” was considered proof of how the EU follows neo-Kantian hospitality that is manifested in dualism and contradictory approach. The study presents a typology that splits co-responsibility into individual/institutional actions and human rights/migration governance. (shrink)

La semiótica del arte es un campo de estudio que implica, más allá de los análisis formales, la revisión de aspectos y operaciones semióticas que solo son comprensibles desde un modelo tríadico. En este sentido, este texto examina las implicaciones del pensamiento de Charles Sanders Peirce en la semiótica del arte contemporáneo. Para eso, revisa sus principales aportes, presenta algunos de los estudios nucleares sobre la interpretación del arte desde la semiótica, y examina las nociones centrales de la teoría de (...) Peirce que constituyen aportes originales para una semiótica del arte contemporáneo. (shrink)

Phillips & Silverstein (P&S, 2003) propose that NMDA-receptor dysfunction may be the fundamental neurobiological mechanism underlying and associating impaired holistic perception and cognitive coordination with schizophrenic psychopathology. We discuss how the P&S hypothesis shares different aspects of the weak central coherence account of autism from both theoretical and experimental perspectives. Specifically, we believe that neither those persons with autism nor those with schizophrenia integrate visuo-perceptual information efficiently, resulting in incongruous internal representations of their external world. However, although NMDA-hypofunction may be (...) responsible for perceptual impairments in schizophrenia and possibly autism, we suggest that it is highly unlikely that NMDA-hypofunction is specifically responsible for the autistic behavioral symptomology, as described by P&S in their target article.

This article undertakes a deconstructive reading of astrobiology’s search for extraterrestrial life. Taking its lead from Derrida’s ‘White Mythology’, it explores ‘metaphor in the text of astrobiology’—and includes within the astrobiological ‘text’ not only scientific publications and work on astrobiology in the philosophy of science, but also ‘life detection technologies’. I situate astrobiology in the tradition of a metaphysical analogy that goes back through the enlightenment and early modern astronomy to the ancient Atomists’ notion of the ‘plurality of worlds’. This (...) analogy, which constitutes an identification of life with being and therefore serves as the conceptual basis for the notion that life must exist on other worlds, experiences a mutation in the middle of the twentieth century when molecular biology refigures life in terms of a scriptural metaphor as text. The result is an aporia whose logic Derrida formalised in ‘White Mythology’. (shrink)

We propose communication pattern logic. A communication pattern describes how processes or agents inform each other, independently of the information content. The full-information protocol in distributed computing is the special case wherein all agents inform each other. We study this protocol in distributed computing models where communication might fail: an agent is certain about the messages it receives, but it may be uncertain about the messages other agents have received. In a dynamic epistemic logic with distributed knowledge and with modalities (...) for communication patterns, the latter are interpreted by updating Kripke models. We propose an axiomatization of communication pattern logic, and we show that collective bisimilarity (comparing models on their distributed knowledge) is preserved when updating models with communication patterns. We can also interpret communication patterns by updating simplicial complexes, a well-known topological framework for distributed computing. We show that the different semantics correspond, and propose collective bisimulation between simplicial complexes. (shrink)

In this essay, a brief analysis of the diplomatic efforts to achieve an accord in re- lation to the climatic change process is made. Particularly, it will analyze the two past Climate Summits (Copenhagen and Cancun). It emphasizes the growing social articulation of climatic politics. Finally, it aims to the birth of a new global responsibility of societies in relation to the human relation towards the planet. Also, it explores the impact of this responsibility on the environment global changes.

The complete description of the interaction between an external electromagnetic field and a charged particle causing it to radiate is one of the most fundamental problems in classical electrodynamics. Here we provide a simple coupled model that describes via the Lagrangian of the physical system the full radiation reaction process resulting from the particle–field interactions which simulate the electromagnetic ones. The particle and field evolution equations obtained from the Lagrangian are studied as an initial value problem giving rise to the (...) particle's radiation reaction equation, which includes the complete interaction with the field. Using stability theory we analyze this equation and prove that every solution is global uniform asymptotically stable, evidencing that the particle coupled to the field radiates. The model proves to be interesting, for it clearly illustrates the particle–field interaction process and shows the radiation's origin. (shrink)

Most model checking techniques for security protocols make a number of simplifying assumptions on the protocol and/or on its execution environment that greatly complicate or even prevent their applicability in some important cases. For instance, most techniques assume that communication between honest principals is controlled by a Dolev-Yao intruder, i.e. a malicious agent capable to overhear, divert, and fake messages. Yet we might be interested in establishing the security of a protocol that relies on a less unsecure channel (e.g. a (...) confidential channel provided by some other protocol sitting lower in the protocol stack). In this paper we propose a general model for security protocols based on the set-rewriting formalism that, coupled with the use of LTL, allows for the specification of assumptions on principals and communication channels as well as of complex security properties that are normally not handled by state-of-the-art security protocol analysers. By using our approach we have been able to formalise all the assumptions required by the ASW protocol for optimistic fair exchange and some of its key security properties. Besides the previously reported attacks on the protocol, we report a new attack on a patched version of the protocol. (shrink)

RESUMEN Este artículo se ocupa de la doctrina del reconocimiento que Hobbes dejó claramente insinuada a lo largo de sus escritos políticos. Para ello, aborda la exposición sistemática del canon de "leyes naturales" que elaborara Hobbes en obras como Elementos de Derecho Natural y Político, Tratado sobre el Ciudadano y Leviatán. Nuestra tesis de fondo es que la exposición de estas leyes, llamadas también por Hobbes "leyes morales", lleva al autor a postular la idea de que la "igualdad natural" de (...) los hombres, por la cual entiende la igualdad de derechos, no ya la igualdad de poder, solo se ve asegurada en la medida en que los individuos se reconozcan intersubjetivamente como portadores de los mismos derechos que, en tanto que hombres, les pertenecen. La tesis señalada pretende evidenciar que, contrario a lo que expone la lectura tradicional de Hobbes, que se concentra en la índole absolutista del poder, Hobbes remonta la posibilidad misma de la vida civil y política, no ya a mediación del Estado absoluto y su poder coercitivo, sino al reconocimiento intersubjetivo de los derechos, el cual obtiene su fuerza normativa de la conciencia moral de cada hombre. Este artículo se propone mostrar que con su postulado Hobbes logra esbozar una protomoral del reconocimiento que repercutiría en el discurso filosófico de la modernidad. Este propósito es uno con el de mostrar las dificultades, las tensiones y los límites del planteamiento hobbesiano. ABSTRACT This paper deals with the doctrine of recognition that Hobbes clearly implied throughout his political writings. To this end, it deals with the systematic exposition of the canon of "natural laws" that Hobbes elaborated in works such as Elements of Natural and Political Law, Treatise on the Citizen and the Leviathan. Our underlying thesis is that the exposition of these laws, also called "moral laws" by Hobbes, leads the author to postulate the idea that the "natural equality" of men, by which he understands equality of rights, not equality of power, is only assured to the extent that individuals are intersubjectively recognized as bearers of the same rights that, as men, belong to them. This thesis seeks to show that, contrary to the traditional reading of Hobbes, which concentrates on the absolutist nature of power, Hobbes traces the very possibility ofcivil and political life, not to the mediation of the absolute State and its coercive power, but to the intersubjective recognition of rights, which obtains its normative force from the moral conscience of each man. The present article intends to show that with its postulate, Hobbes manages to outline a protomoral of recognition, which would not remain without repercussion in the philosophical discourse of modernity. This purpose is one with the one to show the difficulties, the tensions and the limits of the Hobbesian approach. (shrink)

The Venezuelan-Chilean humanist Andrés Bello has been recognized as one of the most distinguished intellectuals of the 19th century—one of the last polymaths of the stature of figures such as Athanasius Kircher, Gottfried Leibniz or Benjamin Franklin. Indeed, his numerous contributions span fields such as grammar, poetry, civil law, diplomacy, education, political theory, philology and philosophy. However, despite having composed one of the most important philosophical treatises ever written in Spanish, his philosophical proposals have not been engaged with a substantial (...) way by scholars of the Anglophone world. Only a few scholars such as... (shrink)
