Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the subject and their approach is still vague. Scientific understanding of global environmental change and the process of designing public policies to face them are characterized by their complexity as well as by epistemic and normative uncertainties. This makes it necessary to problematize the way in which research efforts understand (...) ‘the social’ of climate change. How do ‘the climate’ and ‘the social’ interpenetrate as scientific objects? What does the resulting field look like? Is the combination capable of promoting reflexivity and collaboration on the issue, or does it merely become dispersed with diffuse boundaries? Our paper seeks to answer these and other related questions using Chile as a case study and examining peer-reviewed scientific research on the topic. By combining in-depth qualitative content analysis of each paper with a statistical meta-analysis, we were able to: characterize the key content and forms of such literature; identify divisions and patterns within it; and, discuss some factors and trends that may help explain these. We conclude that the literature displays two competing trends: while it is inclined to become fragmented beyond the scope of the ‘mitigation’ black box, it also tends to cluster along the lines of methodological distinctions traditionally contested within the social sciences. This, in turn, highlights the persistence of disciplinary divisions within an allegedly interdisciplinary field. (shrink)

We aimed to characterize the age of onset of training, age at menarche, menstrual periodicity, and performance perception during the menstrual cycle and examined the impact of these reproductive variables on body composition, morphology, and body weight satisfaction in Brazilian elite futsal players. The study consisted of 115 female Brazilian elite futsal players from the top national teams. Data were collected during the twentieth Women’s Brazil Futsal Cup. Players were interviewed and self-reported their age of onset of training, age at (...) menarche, menstrual periodicity, and the menstrual period, where they performed best. We also asked for what they considered to be their ideal body weight as well as information related to their training. Subsequently, anthropometric measurements were performed to estimate the body composition and determine morphological characteristics. Fifty-nine players were postmenarche-trained and 52 were premenarche-trained. Eighteen, 65, and 28 were classified as early, normal, and late menarche, respectively. Only 11 and 1 had irregular menstrual cycles and were amenorrheic, respectively. Seventy-three, 23, and 9 reported that their game performance was the best at the follicular phase, menses, and luteal phase of the menstrual cycle, respectively. No associations between the four reproductive-related variables were found. Postmenarche-trained players had significant lower age at menarche and higher percentage body fat. The somatotype profile registered lower ectomorphy rate for the postmenarche-trained participants after controlling for covariates. Early menarche group presented higher sum of six skinfold thickness and endomorphy rate compared to normal and late menarche groups. No differences were found when menstrual periodicity groups and best performance groups were compared, except for higher femur width in the regular menstrual cycle group compared to the irregular one. The association between body weight satisfaction and the four reproductive-related variables were not observed. Premenarche-trained Brazilian elite futsal players had the menarche later than the postmenarche-trained athletes. Most of the participants had menarche age classified as “normal,” presented “regular” menstrual cycles and perceived to perform better during the follicular phase of the menstrual cycle. (shrink)

Este artigo não pretende analisar o conjunto da obra de Habermas.

This paper aims to enhance security in IoT device networks through a visual tool that utilizes three projection techniques, including Beta Hebbian Learning (BHL), t-distributed Stochastic Neighbor Embedding (t-SNE) and ISOMAP, in order to facilitate the identification of network attacks by human experts. This work research begins with the creation of a testing environment with IoT devices and web clients, simulating attacks over Message Queuing Telemetry Transport (MQTT) for recording all relevant traffic information. The unsupervised algorithms chosen provide a set (...) of projections that enable human experts to visually identify most attacks in real-time, making it a powerful tool that can be implemented in IoT environments easily.

Los marcos de argumentación son modelos de argumentación derrotable desarrollados en el campo de la inteligencia artificial para analizar la justificación de argumentos según su interacción por medio de ataques. Las semánticas de extensiones para los marcos de argumentación son criterios para sancionar uno (punto de vista escéptico) o varios (punto de vista crédulo) subconjuntos de argumentos justificados. Una forma de evaluar diferentes semánticas de extensiones es considerando si satisfacen o no algunos “principios” (es decir, propiedades razonables o (...) deseables). Además de estas semánticas, también se han propuesto enfoques de la argumentación como juegos de diálogos, a modo de teorías de prueba para encontrar argumentos justificados a través de las estrategias ganadoras de un proponente, y se han demostrado correspondencias entre juegos y extensiones. Como consecuencia, los juegos de diálogos argumentativos se pueden poner en correspondencia con los principios de las semánticas de extensiones. Sin embargo, esas correspondencias no siempre se muestran explícitamente. El objetivo de este trabajo es poner de manifiesto tales correspondencias con casos de juegos simples, uno escéptico y dos variantes de crédulos. (shrink)

En la sociedad uruguaya, que se imagina como un país sin indios, el surgimiento de grupos activistas que se autoadscriben como indígenas (o de ascendencia indígena) ha provocado un amplio espectro de reacciones que van desde la burla hasta la ira. La administración estatal y algunos de los antropólogos más venerados (entre los cuales se encuentran Daniel Vidart y Renzo Pi Hugarte), así como el público en general, se muestran reacios a reconocer la legitimidad de sus reclamos. Esta negativa tiene (...) graves consecuencias jurídicas en un país que no cuenta con un marco legal específico para tratar cuestiones relacionadas con los pueblos originarios, ya que no ha ratificado el Convenio 169 de la Organización Internacional del Trabajo (OIT) —el marco jurídico sobre los derechos de los pueblos indígenas más importante en el ámbito internacional debido a su carácter vinculante para los Estados que lo ratifican—. En este artículo, discuto la pertinencia de los estudios coloniales para la comprensión de algunos procesos históricos en el Cono Sur. También intento arrojar algo de luz sobre el caso de Uruguay a través del análisis de la noción marxista de acumulación primitiva, que explica el proceso de despojo que sufrieron los diversos grupos indígenas que poblaron el territorio antes de la llegada de los colonos europeos. Con suerte, el análisis permitirá comprender las reacciones —a veces airadas y violentas— de la sociedad uruguaya, ante la reemergencia de colectivos indígenas en un país donde se pensaba que se encontraban extintos. La reaparición charrúa en la arena pública pone en duda la legitimidad de la posesión de la tierra tanto por parte del Estado como de sus habitantes. (shrink)

Proponho uma investigação do “debate” Waldron vs. Dworkin, discutindo o problema dos desacordos morais e se o judicial review é, de fato, válido. Na medida que Waldron desferiu severas críticas a Dworkin, defendendo que a “última palavra” deve ser do Legislativo, nesse cenário, apresento uma defesa à concepção de Dworkin. Chego à conclusão de que os autores, na verdade, não possuem uma discordância em si, mas pontos de conexão, segundo a qual somente é possível a deferência aos legisladores quando há (...) uma democracia devidamente sólida e coerente, o que não é o caso da narrativa histórica e contemporânea. Foi utilizado o método dedutivo, conduzido sob uma pesquisa bibliográfica, com o marco teórico a “discussão” travada pelos filósofos para este ensaio. (shrink)

El propósito de este trabajo es ofrecer un análisis de la discusión sobre el canibalismo y los sacrificios humanos de los indígenas en el contexto de la controversia entre Las Casas y Sepúlveda. Dicho análisis es muy relevante, en tanto que permite observar las raíces más remotas del actual derecho de intervención y de la doctrina de los derechos humanos. Para tal fin, el autor empieza con una rápida descripción de los motivos que condujeron a la disputa de Valladolid, al (...) tiempo que enuncia los cuatro puntos en discusión. En segundo lugar, realiza una descripción más o menos detallada del cuarto argumento de la controversia, que trata en concreto sobre los sacrificios humanos y el canibalismo indígena. Y concluye mostrando que, al justificar estas prácticas, Las Casas busca ante todo la integración de las culturas indígenas en el marco general del conocimiento histórico universal. (shrink)

El presente trabajo se articula en dos partes; en la primera reconstruyo el tema del mismo, a saber: la cuestión de la proletarización y la politización de los intelectuales, tal como fue planteada por W. Benjamin; en la segunda, estudio dicha problemática desde algunos conceptos centrales de dos marcos teóricos para los cuales aquélla no fue pensada, la filosofía de G. Simmel y la sociología del conocimiento de K. Mannheim. Pongo en relación con éstos además algunas referencias de la (...) filosofía del lenguaje contemporánea. El objetivo de todo ello no es el de obtener una nueva respuesta a la problemática, cuanto reconstruir las condiciones que la posibilitarían. (shrink)

Las llamadas "estrategias deflacionistas" han constituido una alternativa relativamente popular para enfrentar el problema de la presunta ineficacia causal de los estados mentales en el marco del materialismo no reduccionista. Las propuestas de Lynn Baker y Tyler Burge, desarrolladas en el marco de esta estrategia, coinciden en señalar la necesidad de limitar la importancia de la reflexión metafísica y privilegiar el análisis de la explicación mentalista como fuente para la solución de los problemas de la causación mental. En contra de (...) esta pretensión, sostenemos que, aun cuando fuera posible reflexionar sobre la causación mental sin recurrir a la metafísica, las dificultades derivadas de lograr una caracterización de lo que constituye una explicación psicológica satisfactoria, sumadas a la competencia explicativa generalizada en la teorización psicológica, resultan obstáculos casi insalvables para estas estrategias. /// The so called "deflationary strategies" have been a relatively popular option for dealing with the problem of the supposed causal inefficacy of mental states in non-reductive materialism. The proposals of both, Lynn Baker and Tyler Burge, developed in the context of this strategy, point out the need to reduce the weight of metaphysical reflection in favor of the analysis of mental explanation as a source to solve the problems of mental causation. Contrary to this claim, I hold that, even if reflection about mental causation is possible without metaphysics, the difficulties for these strategies in building a notion of psychological explanation, in addition to the generalised explanatory competence in psychological theorisation, are almost insuperable.

No século XIX, o progresso da biologia evolutiva esteve pautado por dois programas de pesquisa: um de desenvolvimento mais amplo e com maior reconhecimento institucional, que foi o programa filogenético; e outro, o programa adaptacionista, cujo desenvolvimento foi mais restrito ou até mesmo marginal. Fritz Müller (1822-1897) contribuiu para ambas as agendas de pesquisa. Sua contribuição pioneira para o programa filogenético, está em seu livro Für Darwin. Instigado pelo próprio Darwin, também obteve resultados de pesquisa que foram marcos para (...) a consolidação do programa adaptacionista, como por exemplo, seus trabalhos sobre mimetismo. (shrink)

RESUMENSegún un punto de vista muy difundido, y alineado con la concepción nómica de la explicación causal, la biología funcional está sometida a un régimen de heteronomía explicativa en cuyo marco los fenómenos orgánicos deben explicarse causalmente recurriendo a leyes oriundas de la física y la química. En contra de esa perspectiva, la concepción experimental de la causación permite entender la naturaleza de muchas explicaciones biológicas que, sin hacer referencia a leyes causales - físicas, químicas o de cualquier otra naturaleza (...) - se legitiman por el hecho de ponernos en condiciones de controlar experimentalmente fenómenos relativos al funcionamiento y a la constitución de los organismos. Esas explicaciones suponen invariantes locales que muchas veces, pero no necesariamente, podrán llegar a ser caracterizados como instancias de leyes físico-químicas. ABSTRACTIn accordance with a widespread point of view, aligned with the nomological conception of causal explanation, Functional Biology is subjected to a regime of explanatory heteronomy under which, organic phenomena should be causally explained by using laws of Physics and Chemistry. Against this perspective, the experimental conception of causation allows us to understand the nature of many biological explanations that, without make any reference to causal laws - physical, chemical or of other nature - are legitimized because they permit the experimental control of phenomena that have to do with the functioning and development of organisms. These explanations involve local invariants that often, but not necessarily, may be characterized as instances of physical and chemical laws. (shrink)

"El nacimiento de la fenomenologí­a.

Husserl se convirtió con ello en el fundador de la Fenomenologí­a, cuyo desarrollo marco, gradualmente, a toda la filosofí­a más allá de las fronteras de su natal Alemania. Heidegger, Ingarden, Schí¼tz, Sartre, Merleau Ponty, Lévinas o (...) Ricoeur, por ejemplo, son autores cuya obra serí­a impensable sin la veta del pensamiento que abrió Husserl.

En tal sentido, un irrebasable conjunto de derechos básicos funciona como marco para la participación ciudadana y opera como parámetro para la presentación de las virtudes cívicas.

Estas virtudes son conceptualmente diferenciadas de los valores cívicos como forma de (...) establecer criterios normativos diferenciales para la implementación de políticas públicas. Por último se presentan tres dimensiones para la educación ciudadana: una de corte estrictamente curricular, una personal vinculada al desarrollo de las capacidades básicas del ciudadano, y una dimensión social que tiene que ver con el rol de las instituciones de la sociedad civil.

Rastrear en la escritura de Jacques Derrida la existencia de un pensamiento otro de la materialidad no es tarea sencilla. Sin embargo, es la tarea que se propone delinear, al menos en sus coordenadas generales, el presente artículo. Ello, inicialmente, implicaría seguir una serie de elementos propios de la tradición presocrática que estarían inscritos a modo de huellas en la escritura deconstructiva. En tal sentido, nociones como las de átomo, vacío y movimiento serán consideradas, en diversos momentos del presente texto, (...) en el marco de una interpretación contemporánea de la divisibilidad y fragmentación de lo existente. A partir de estas consideraciones y su relación con la escritura en el pensamiento de la deconstrucción se sostendrá el carácter cuasi-trascendental de la materia. (shrink)

El objetivo de este trabajo es poner al descubierto los principales valores cognitivos y epistemológicos desde los que Warren Weaver puso en marcha el Programa de Biología Experimental, un programa que llevado a cabo desde la presidencia de la división de ciencias naturales de la Fundación Rockefeller, marcó y condicionó en buena medida el posterior desarrollo de la investigación biológica. Para tal fin se mostrará, en primer lugar, cómo fue la llegada de Weaver a la Fundación Rockefeller, así como las (...) razones bajo las cuáles el consejo de esa institución decidió entre 1932 y 1933 dar prioridad a las investigaciones biomédicas, y la manera por la cual lo hicieron. En un segundo momento, el más extenso e importante, veremos algunos de los elementos más significativos de la perspectiva epistemológica y cognoscitiva de de Weaver. Finalizaremos viendo cómo esa perspectiva, desarrollada en conexión con el Programa de Biología Experimental, inter-actuó con la visión reduccionista de la biología a la que el programa parecía apuntar. The aim of this article is to uncover the main cognitive and epistemological values that influenced Warren Weaver in starting the Experimental Biology Program, a program carried out from the time that he became president of the Natural Sciences Division of the Rockefeller Foundation, and which significantly marked and conditioned the subsequent development of biological research. To this end, we first describe the arrival of Warren Weaver at the Rockefeller Foundation, and the reasons for which the Board of this Foundation, between 1932 and 1933, decided to prioritize biomedical research, and the manner in which they did so. Then, secondly, in the largest and most important part of the article, we will present some of the most significant elements of Weaver's epistemological and cognitive perspective. Finally, we will show how this perspective, developed in connection with the Experimental Biology Program, interacted with the reductionist view of biology to which the program seemed to point.

Este trabajo investiga las interrelaciones entre la regulación y los as-pectos económicos y ambientales en una comunidad de agricultores familiares en la región conocida como Zona da Mata Mineira, en el estado brasileño de Minas Gerais. El estudio es producto de una acti-vidad de extensión realizada entre 2016 y 2018, y tuvo como objetivo asesorar a los pequeños productores en el proceso de adecuación legal de la producción. Durante este período se realizaron cerca de cinco reuniones entre investigadores y comuneros, (...) en las que se analizaron las dificultades encontradas por los pequeños productores en relación con el referido proceso. Las experiencias reportadas fueron confron-tadas con el régimen legal regulatorio para la actividad acuícola en Brasil, tomando como categorías de análisis los atributos de norma-tividad y facticidad del sistema legal. Se concluyó que la regulación ambiental en el área de la acuicultura en Brasil, diseñada para grandes productores, carga de manera desproporcionada a los pequeños pro-ductores, generando un desequilibrio económico injustificado. Como aporte a la teoría, se propone, en definitiva, la formulación de un con-cepto de regulación jurídica inclusiva, cuyos rasgos distintivos inclu-yen la participación social y la promoción de la alfabetización jurídica como derecho fundamental.

We prove that the category of Nachbin’s compact ordered spaces and order-preserving continuous maps between them is dually equivalent to a variety of algebras, with operations of at most countable arity. Furthermore, we observe that the countable bound on the arity is the best possible: the category of compact ordered spaces is not dually equivalent to any variety of finitary algebras. Indeed, the following stronger results hold: the category of compact ordered spaces is not dually equivalent to any finitely accessible (...) category, any first-order definable class of structures, and any class of finitary algebras closed under products and subalgebras. An explicit equational axiomatisation of the dual of the category of compact ordered spaces is obtained; in fact, we provide a finite one, meaning that our description uses only finitely many function symbols and finitely many equational axioms. In preparation for the latter result, we establish a generalisation of a celebrated theorem by Mundici: our result—whose proof is independent of Mundici’s theorem—asserts that the category of unital commutative distributive lattice-ordered monoids is equivalent to the category of what we call MV-monoidal algebras.Abstract taken directly from the thesis.E-mail: [email protected]: https://air.unimi.it/retrieve/handle/2434/812809/1698986/phd_unimi_R11882.pdf.

There are communities in which disadvantaged groups experience severe inequality. For instance, poor and indigent families face many difficulties accessing their social rights. Their condition is largely the consequence of the wrong choices of those in power, either historical or more recent choices. The lack of opportunities of these deprived citizens is due to state omissions. In such communities, it is not unusual for homeless members of these particular groups to occupy abandoned lands and build their shelters there. However, almost (...) everywhere, these actions constitute a crime. The typical response to this situation is prosecution and punishment. In this paper, I will defend the occupation of public places as a consequence of the failure of governments to solve the problem of housing, and I will argue that we must distinguish a social claim from a crime and avoid the use of criminal law in these “occupation cases”. I will also argue that our right—as a community—to blame and punish these “squatters” is eroded by the fact that we perpetrated their situation of injustice. (shrink)

Dung’s argumentation frameworks have been applied for over twenty years to the analysis of argument justification. This representation focuses on arguments and the attacks among them, abstracting away from other features like the internal structure of arguments, the nature of utterers, the specifics of the attack relation, etc. The model is highly attractive because it reduces most of the complexities involved in argumentation processes. It can be applied to different settings, like the argument evaluation of an individual agent or the (...) case of dialectic disputes between two agents (pro and con), or even in multi-agent collective argumentation. The latter case involves agents with possibly different arguments and/or opinions on how to evaluate them, leading to the possibility of considering multiple sets of arguments and attack relations. Two basic questions can be asked here, namely ‘what to aggregate’ and ‘how to aggregate’. The former concerns what kinds of entities do the agents intend to choose (arguments, attacks, assessments, etc.), while the second one focuses on which aggregation mechanisms yield rational choices (voting on arguments, merging procedures to obtain a common argumentation framework, deliberation processes, etc.). In particular, the question about the rationality of a collective argument choice relates this topic to Social Choice and Judgment Aggregation theories, while its associated strategic issues relate it to Game Theory. The research efforts on the disparate problems elicited by collective argumentation have generated a considerable corpus of literature that deserves an orderly evaluation. This survey is intended as a contribution to that end. (shrink)

ABSTRACTContrary to what some critics of epistemic democracy claim, the association between democracy and truth does not necessarily make the former inhospitable to conflict, contestation, and pluralism. With the help of John Stuart Mill and William James, truth can be interpreted so as to make it compatible with a democratic politics that appreciates conflict and dissent. In some circumstances, truth claims are politically relevant and should become the object of democratic deliberation.

The problems that arise from the presence of self-attacking ar- guments and odd-length cycles of attack within argumentation frameworks are widely recognized in the literature on defeasible argumentation. This paper introduces two simple semantics to capture different intuitions about what kinds of arguments should become justified in such scenarios. These semantics are modeled upon two extensions of argumentation frameworks, which we call sustainable and tolerant. Each one is constructed on the common ground of the powerful concept of admissibility introduced by (...) Dung in [10]. The novelty of this approach consists in viewing the admissibility of a subset of arguments as relative to potentially challenging subsets of arguments. Both sustainable and tolerant semantics are more credulous than preferred semantics (i.e. they justify at least the same arguments, and possibly more). Given certain sufficient conditions they coincide among them as well as with other semantics introduced by Dung. (shrink)

In this paper we provide a compact presentation of the verisimilitudinarian approach to scientific progress (VS, for short) and defend it against the sustained attack recently mounted by Alexander Bird (2007). Advocated by such authors as Ilkka Niiniluoto and Theo Kuipers, VS is the view that progress can be explained in terms of the increasing verisimilitude (or, equivalently, truthlikeness, or approximation to the truth) of scientific theories. According to Bird, VS overlooks the central issue of the appropriate grounding of scientific (...) beliefs in the evidence, and it is therefore unable (a) to reconstruct in a satisfactory way some hypothetical cases of scientific progress, and (b) to provide an explanation of the aversion to falsity that characterizes scientific practice. We rebut both of these criticisms and argue that they reveal a misunderstanding of some key concepts underlying VS. (shrink)

Theory change is a central concern in contemporary epistemology and philosophy of science. In this paper, we investigate the relationships between two ongoing research programs providing formal treatments of theory change: the (post-Popperian) approach to verisimilitude and the AGM theory of belief change. We show that appropriately construed accounts emerging from those two lines of epistemological research do yield convergences relative to a specified kind of theories, here labeled “conjunctive”. In this domain, a set of plausible conditions are identified which (...) demonstrably capture the verisimilitudinarian effectiveness of AGM belief change, i.e., its effectiveness in tracking truth approximation. We conclude by indicating some further developments and open issues arising from our results. (shrink)

The body of Eva in Thomas Aquinas The constitution of the first female body or the body of Eva presents several physical and metaphysical problems, problems that have gone through the centuries and reach the present, generating social and cultural consequences for women. The non-existence of parents demands from Aquino answers that go beyond the anthropological and biological and lead to the search of philosophical answers intertwined with the theological ones. Thomas Aquinas provides rational answers although the background is of (...) faith, and even, with literal interpretations of the Sacred Scriptures now abandoned. The Aquinate makes an intellectual effort to find answers in a rational field because the matter of the body of the first woman brings difficulties for its elucidation and understanding. As in other parts of his extensive work, Thomas Aquinas, follows the biological and physical works of Aristotle. Although the Aristotelian background is in line with Christian thought, Aquinas shows his extraordinary capacity for synthesis between the faith received and reason argued, between revelation and the principles of reason.

Micro Credit (MC) programs lend money to poor borrowers using innovative mechanisms such as group lending under joint liability while successfully accounting for the presence of asymmetric information in underdeveloped financial markets. MC programs have achieved what the conventional financial institutions and the government have not been able to: lend to the poor, impressive loan recuperation, and a positive impact in poverty reduction. This article analyzes the performance of ALSOL, an MC program in Chiapas, México, for 2151 participants in urban (...) and rural areas for the time period between July 2000 and July 2001. While loan recuperation is high (95%), administrative costs also remain high. Socially responsible lenders and donors play a key role in providing continuous funding to MC programs and assisting in reducing the level of poverty. (shrink)
