Long-term ecological research (LTER), addressing problems that encompass decadal or longer time frames, began as a formal term and program in the United States in 1980. While long-term ecological studies and observation began as early as the 1400s and 1800s in Asia and Europe, respectively, the long-term approach was not formalized until the establishment of the U.S. long-term ecological research programs. These programs permitted ecosystem-level experiments and cross-site comparisons that led to insights into the biosphere’s structure and function. The holistic (...) ecosystem approach of this initiative also allowed the incorporation of the human-dimension of ecology and recently has given rise to a new concept of long-term socio-ecological research (LTSER). Today, long-term ecological research programs exist in at least thirty-two countries (i.e., members of the International Long-Term Ecological Research Network, ILTER). However, consolidation of the international network within the long-term socio-ecological research paradigm still requires: (1) inclusion of certain remote regions of the world, such as southwestern South America, that are still poorly represented; (2) modifications of the type of research conducted, such as integrating social and natural sciences with the humanities and ethics; and (3) the incorporation of findings and results into broader social and political processes. In this context, a nascent long-term socio-ecological research network in Chile, which extends over the longest latitudinal range of temperate forest in the Southern Hemisphere, adds a new remote region to international long-term ecological research previously overlooked. In addition, collaboration with the University of North Texas and other international partners helps to further develop an interdisciplinary approach for the integration of the ecological sciences and environmental philosophy together with traditional ecological knowledge, informal and formal education, policy, the humanities, socio-political processes, and biocultural conservation.

El propósito de este estudio es dilucidar algunos de los rasgos distintivos de la concepción del ser humano que mantiene Jürgen Habermas y sus implicaciones en la teoría de la acción comunicativa. De este modo, se trata de mostrar que la antropología habermasiana se singulariza por adoptar una perspectiva naturalista y darwinista. En la primera parte, se analiza el legado epistemológico de Darwin como un programa de investigación y se contrastan los estudios de Habermas sobre antropología biológica con las últimas (...) investigaciones en genética y paleontología. En la segunda parte, se presenta la propuesta de Habermas de afrontar un dualismo epistemológico mediante un naturalismo débil noreduccionista, como crítica de la metafísica moderna y estructurador de un nuevo realismo.

Refletimos sobre a violência que frequenta as instituições escolares partindo do pressuposto de que ao se apresentar na escola de maneira molecular, a violência evidencia o reflexo do que já se encontra posto na sociedade. No que se refere à escola, é necessário pensar o fenômeno violento como uma realidade que cada dia mais toma o cenário escolar e demanda de educadores, alunos e famílias respostas novas e inventivas aos problemas advindos da complexa relação a que a violência os expõem. (...) Tendo vista uma compreensão mais detalhada do fenômeno, realizamos uma análise da violência que adentra os muros da escola, servindo-nos de uma classificação muito utilizada entre os teóricos pesquisadores do assunto: a violência da, na e contra a escola. Estudando separadamente cada uma destas formas de violência, acreditamos poder abarcar, ainda que não tão profundamente quanto o tema exige, as formas com que a violência tem sido vivenciada na escola por seus sujeitos discentes e docentes e por toda a comunidade em que ela se insere. Refletir sobre o fenômeno violento e suas implicações, abrindo espaços de fala dentro das instituições escolares para que ele seja discutido e problematizado, pensamos ser um dos possíveis caminhos para superação da violência.

RESUMO O intuito deste artigo é estudar o objetivo principal da estética musical de Boulez, para o início das comemorações de seus 90 anos, desde certas categorias de Deleuze, considerando que elas nos permitem compreender e delinear uma lógica da sensação sonora. Se Deleuze se ocupou em detalhe do trabalho de Francis Bacon, por exemplo, a fim de criar uma "lógica da sensação visual" em que o conceito de "Figura" fosse central, propomos que o trabalho musical de Boulez, analisado a (...) partir do pensamento de Deleuze, possa mostrar os momentos decisivos de uma "lógica da sensação sonora." Por meio de alguns trabalhos de Boulez podemos ver dois elementos muito importantes para nossa pesquisa dados na estrutura instalada pela filosofia de Deleuze. Esses dois elementos que darão forma a este artigo são: as "figuras" da música e as "forças" do som expressivo. ABSTRACT This article aims to study the main objective of musical aesthetics of Boulez, to begin to commemorate 90 years, since certain categories of Deleuze, as they allow us to understand and outline a logic of sound sensation. If Deleuze worked in detail the work of Francis Bacon, for example, to create a "logic of visual sensation" where the concept of "Figure" is central, we propose that the musical work of Boulez, analyzed from Deleuze's thought, be possible to show the decisive moments of a "logic of sound sensation." Along some works by Boulez we can see two very important elements for our research in the framework installed Deleuze's philosophy are given. These two elements will shape this article are: the "figures" of music and the "forces" expressive sound. (shrink)

Este artículo sitúa el marco fenomenológico-hermenéutico en torno al otro y desarrolla la hipótesis de que la cuestión de la intersubjetividad es central para entender las categorías fundamentales relativas a todo pensar acerca de la alteridad que se plantean en filosofía, en literatura y en los discursos sociopolíticos, ya que implican una cuestión central acerca de la analogía. Asumiendo la obra de E. Husserl, y en especial los comentarios contemporáneos sobre Phänomenologie der Intersubjektivität, se avanza en un enfoque interdisciplinario del (...) “otro” y del “alter ego” --propias de una analítica de la experiencia humana--, demostrando que la experiencia de la sociabilidad se forja a partir de vivencias originarias que refieren a un determinado modo de entender el vínculo analógico entre el yo y el otro y los otros. This article situates the phenomenological-hermeneutical framework around the other and develops the hypothesis that the issue of intersubjectivity is central in understanding the fundamental categories related to any thought regarding alterity which are proposed in philosophy, in literatura, and in socio-political discourse, since it implies a central questioning about the analogy. Assuming the work of E. Husserl, and especially the contemporary comments on Phänomenologie der Intersubjektivität,we advance toward an interdisciplinary focus of the “other” and the “alter ego” --proper to an analysis of the human experience--, demonstrating that the experience of sociability is forged from the original life experiences that refer to a determined way of understanding the analogic relationship between the self and the other and the others.

O presente artigo visa demonstrar que os fins da política podem ser considerados como fins transpolíticos na medida em estão imbricados com o fim último do homem. O pensamento político de Tomás de Aquino (1225-1274) está exposto na sua filosofia prática ou moral, por exemplo, nas suas questões sobre as virtudes, de um modo especial quando trata da prudência e da justiça, bem como nas discussões sobre as formas de governo, as leis, o bem comum e o direito. Santo Tomás, (...) de certa forma, retoma as ideias de Aristóteles, todavia, trata da civitas ou melhor do regnum christiano, e não da polis grega. Os fins principais da política são: o bem comum, a vida virtuosa dos cidadãos e a felicidade (beatitude) na fruição divina. Demonstrar-se-á que o fim último do homem é um só, sendo os demais antecedentes ou meios para alcançar aquilo que todos desejam: a felicidade. Sem desconsiderar as diversas obras em que o autor trata de temas políticos, contudo, este artigo abordará as ideias da obra De regno. (shrink)

La educación universitaria enfrenta grandes desafíos como el de gestionar el cambio que se ajuste a las demandas de la sociedad contemporánea. Una de las formas para sensibilizar al mundo académico y facilitar la innovación es la evaluación y la autoevaluación. En este trabajo se realizó un análisis tendencial de los diversos enfoques y modelos del proceso de evaluación y autoevaluación institucional; así como de las propensiones actuales del proceso autoevaluativo de las instituciones de la educación superior a través del (...) concepto de calidad. One of the biggest challenges that University education faces nowadays, is to manage the corresponding changes that our contemporary society demands. A way to sensitize the academic world and to make innovation easier is through assessment and self-appraisal. This research work carried out a tendentious analysis of the different approaches and models of the institutional assessment and self-appraisal processes; as well as, of the current tendencies of the institutional self-appraisal process in higher education, by analyzing the concept of quality.

Entrevista com o Rabino Dr. Fishel Szlajen.

Tomas Aquinas defined truth as the correspondence between things and understanding. Castro Alves paints the horror of the slave nautical traffic. In his essay On the Concept of History, Walter Benjamin reminds us: “The tradition of the oppressed teaches us that the ‘emergency situation’ in which we live is the rule.” This ‘emergency situation’ was Fascism. Albert Camus defended his romance La Peste against the accusation of Roland Barthes that is was “dehors de l’histoire”, pointing out that it was not (...) only about the recent historical phenomenon of Fascism, but also about the permanent risk of its rebirth. Agnes Heller associates faith with prejudice and alienation. The following article will explore the Thomist concept of truth, Benjamin’s concept of history, Camus’ allegory of the plague, Agnes Heller’s notion of faith and Castro Alves’ powerful denouncement of slave traffic, to better criticize the phenomenon of post-truth, a rebirth of fascist information practices.

Learning equivalence classes of acyclic models with latent and selection variables from multiple datasets with overlapping variables is discussed. The problem of inferring the presence of latent variables, their relation to the observables, and the relation among themselves, is considered. A different approach for identifying causal structures, one that results in much simpler equivalence classes, is provided. It is found that the computational cost is much higher than the procedure implemented, but if datasets are individually of modest dimensionality, it might (...) be doable in practice. From the point of view of search algorithms for optimizing structure, much of the machinery of combinatorial optimization could optimize the penalized composite likelihood score by enforcing constraints such that the independence models over different subsets of variables agree on the overlapping sets.

Alchourrón devoted his last years to the analysis of the notion of defeasible conditionalization. He developed a formal system capturing the essentials of this notion. His definition of the defeasible conditional is given in terms of strict implication operator and a modal operator f which is interpreted as a revision function at the language level. In this paper, we will point out that this underlying revision function is more general than the well known AGM revision [4]. In addition, we will (...) give a complete characterization of that more general kind of revision and will show how permits to unify models of revision given by other authors. Alchourrón dedicó sus últimos años al análisis de la noción de condicionalización derrotable. Desarrolló un sistema formal que captura los aspectos esenciales de esta noción. Su definición de condicional revisable está dada en términos del operador de implicación estricta y un operador modal f el cual es interpretado en el nivel del lenguaje como una función de revisión. En este trabajo señalamos que la función de revisión subyacente es más general que la bien conocida función de revisión de AGM. Además, presentaremos una caracterización completa de una clase de revisión más general y mostraremos cómo nuestro modelo permite unificar los modelos de revisión propuestos por otros autores.

O presente artigo fundamenta-se em uma pesquisa bibliográfica com o propósito de instigar debates acerca das estratégias adotadas por instituições e figuras proeminentes na tentativa de obscurecer ou mesmo negar a significativa contribuição das multidões de africanos escravizados que chegaram a estas terras, em larga medida, para o enriquecimento do país. Adicionalmente, baseia-se em uma pesquisa netnográfica com o desígnio de analisar as controvérsias e polêmicas presentes nas plataformas de mídia eletrônica relacionadas às alegações de envolvimento e benefício do Banco (...) do Brasil com o sistema econômico escravista e o tráfico ilegal de escravos. Ademais, o estudo almeja evidenciar que as frequentes tentativas de obliteração ou negação dos episódios de abuso, violência e perseguição contra os africanos e seus descendentes reforçam a percepção de que o reconhecimento e a valorização da contribuição dos negros dependem, em grande medida, de um contínuo exercício de revisão histórica e de um tratamento fiel e apropriado da narrativa histórica.

A alma é, sem dúvida, um dos problemas que mais interessou a Santo Agostinho; ele a define como uma substância partícipe da razão adequada ao governo de um corpo. A alma não tem quantidade corporal, contudo, é uma coisa grande. Este estudo pretende refletir sobre os sete graus de atividade da alma, os quais o autor apresenta na sua obra De quantitate animae. São eles: a animação, a sensação, a arte, a virtude, a tranquilidade, o ingresso e a contemplação. The (...) soul is undoubtedly one of the problems that most interested St. Augustine. He defines it as a substance participating of reason, adequate for the government of a body. The soul has no corporal quantity, but is nevertheless a great thing. This study aims to reflect on the seven degrees of activity of the soul, which the author presents in his work De quantitate animae. The are: animation, sensation, art, virtue, tranquility, ingress and contemplation. (shrink)

Las investigaciones que Carlos Alchourrón desarrolló en la Filosofía del Derecho se vincularon, desde inicios de la década de 1980, con problemáticas críticas de la Inteligencia Artificial. Su contribución a la construcción de una lógica de las normas se conectó rápidamente con la deducción automática y los Sistemas Expertos Jurídicos. Su preocupación por la cuestión de los conflictos de obligaciones que pueden plantearse en un sistema normativo cuando el juez se enfrenta a la necesidad de emitir un veredicto considerando ciertos (...) hechos, se vinculó, en sus trabajos, con la noción más general de "condicionales derrotables" y con la formalización del Razonamiento No Monótono. Pero su contribución de mayor impacto fue aquella derivada de la búsqueda de una solución al problema de los resultados múltiples que surgen de la derogación de una norma en un sistema jurídico, problema que puede ser visto, en un contexto epistémico, como el de la contracción de un conjunto de creencias. Su enfoque constructivo, que desarrolló con David Makinson, convergió con el axiomático elaborado por Peter Gärdenfors, dando lugar al surgimiento de la teoría de los Cambios Racionales de Creencias, más conocida como AGM, teoría que fue adoptada en IA como un modelo standard para la especificación de las actualizaciones de Bases de Conocimiento, operaciones que, habitualmente, involucran la introducción de una nueva creencia que puede ser inconsistente con las anteriores. ¿Por qué AGM adquirió rápidamente carta de ciudadanía en IA, al punto de que su influencia, medida según la cantidad de menciones bibliográficas del artículo fundacional de 1985, se ha duplicado en la última década? Mostraremos en este trabajo que la teoría apareció en un momento de crisis de la IA y que el alto nivel de abstracción del modelo de AGM era lo que muchos investigadores de la disciplina estaban buscando. El presente artículo, luego de describir la génesis de AGM, realiza un análisis histórico de las circunstancias en las cuales la teoría se introdujo en la IA y una evaluación cuantitativa y cualitativa de su impacto en dicha disciplina. The main lines of research that Carlos Alchourrón developed in the Philosophy of Law, were connected, from the beginnings of the 80' s, to some critical problems in the Artificial Intelligence. His contributions to the construction of a logic of norms were rapidly linked to automatic deduction and the Legal Expert Systems. His concerns for the conflict of obligations that could arise in a normative system when a judge has to issue a ruling taking some particular facts into account were associated in his work with the more general notion of "defeasible conditionals" and with the formalization of Non Monotonic Reasoning. But his most relevant contribution was the one derived from the search of a solution to the problem of multiple outcomes resulting from the derogation of a norm in a legal corpus, which may be considered -within an epistemic framework- analogous to the contraction of a set of beliefs. The constructive approach he worked out with David Makinson converged with Peter Gärdenfors' axiomatic, giving rise to the formulation of the theory of Rational Changes of Belief, which was adopted in AI as a model for the specification of the updates of Knowledge Bases as it usually involves a new belief that may be inconsistent with the old ones.

From the notion of “minor literature” proposed by Gilles Deleuze, the article comprises a general approach to the writings of the Chilean poets Tomás Harris and Nicolás Miquea, to raise the possibility of a “minor reading”, as an exercise of reflection on both authors. From a broad theoretical approach, the article also explores the identity of poetry as health event, otherness, and relational aesthetics for the conceptual development of a “poetic trafficker”.

Church's Undecidability Theorem is one of the meta-theoretical results of the mid-third decade of the last century, which along with other limiting theorems such as those of Gödel and Tarski have generated endless reflections and analyzes, both within the framework of the formal sciences, that is, mathematics, logic and theoretical computation, as well as outside them, especially the philosophy of mathematics, philosophy of logic and philosophy of mind. We propose, as a general purpose of this article, to formulate Church's Undecidability (...) Theorem and present the main ideas of its demonstration. In order to carry out the first objective, we need to introduce and explain the notions of recursive function and numbering used by Gödel, which will allow to formally and rigorously enunciate Church's Theorem. After we enunciate Church's Theorem of Unspeakability in a formal and rigorous manner, we will present the main ideas of the proof of Church's Undecidability Theorem for First Order Logic, which uses Robinson's axiomatic system for arithmetic and four facts about himself: In Robinson's system for arithmetic recursive functions are representable Robinson's system is undecidable, The number of axioms proper to the Robinson system is finite and The logical calculation of the Robinson system is equal to the calculation of the first-order logic.
