El siguiente artículo busca ser un aporte teórico y metodológico para quienes se enfrentan a la tarea de realizar análisis del discurso. En ese sentido, este texto está especialmente dirigido a estudiantes que piensan llevar a cabo esta tarea en sus tesis de egreso. Para lograr este desafío teórico y metodológico, a lo largo del artículo se responderán dos preguntas: ¿Por qué analizar el discurso? Y ¿cómo hacer análisis del discurso? Como vemos, la primera pregunta es de naturaleza explicativa y (...) la segunda de carácter metodológica.The following article seeks to be a theoretical and methodological contribution for those who are faced with the task of realizing discourse analysis. In this sense, this text is especially directed to students who intend to perform this task in their thesis. In order to achieve this theoretical and methodological challenge, all along the article, it will be answering two questions: Why doing discourse analysis? and How is discourse analysis performed? As we may observe, the first question is of an explicative nature and the second has a methodological character. (shrink)

Ship-type identification in a maritime context can be critical to the authorities to control the activities being carried out. Although Automatic Identification Systems has been mandatory for certain vessels, if a vessel does not have them voluntarily or not, it can lead to a whole set of problems, which is why the use of tracking alternatives such as radar is fully complementary for a vessel monitoring systems. However, radars provide positions, but not what they are detecting. Having systems capable of (...) adding categorical information to radar detections of vessels makes it possible to increase control of the activities being carried out, improve safety in maritime traffic, and optimize on-site inspection resources on the part of the authorities. This paper addresses the binary classification problem (fishing ships versus all other vessels) using unbalanced data from real vessel trajectories. It is performed from a deep learning approach comparing two of the main trends, Convolutional Neural Networks and Long Short-Term Memory. In this paper, it is proposed the weighted cross-entropy methodology and compared with classical data balancing strategies. Both networks show high performance when applying weighted cross-entropy compared with the classical machine learning approaches and classical balancing techniques. This work is shown to be a novel approach to the international problem of identifying fishing ships without context. (shrink)

Currently, the most used method to measure brain activity under a non-invasive procedure is the electroencephalogram (EEG). This is because of its high temporal resolution, ease of use, and safety. These signals can be used under a Brain Computer Interface (BCI) framework, which can be implemented to provide a new communication channel to people that are unable to speak due to motor disabilities or other neurological diseases. Nevertheless, EEG-based BCI systems have presented challenges to be implemented in real life situations (...) for imagined speech recognition due to the difficulty to interpret EEG signals because of their low signal-to-noise ratio (SNR). As consequence, in order to help the researcher make a wise decision when approaching this problem, we offer a review article that sums the main findings of the most relevant studies on this subject since 2009. This review focuses mainly on the pre-processing, feature extraction, and classification techniques used by several authors, as well as the target vocabulary. Furthermore, we propose ideas that may be useful for future work in order to achieve a practical application of EEG-based BCI systems toward imagined speech decoding. (shrink)

La resistencia comunitaria noviolenta es una estrategia para transformar conflictos. Este estudio contiene el análisis de la Asamblea Municipal Constituyente (AMC) como proceso de resistencia en Mogotes, Santander, Colombia. En el desarrollo del artículo se retoma la experiencia de investigación llevada adelante en el municipio para indagar acerca de la contribución de las redes sociales en el desarrollo y mantenimiento de las políticas de identidad en el proceso de resistencia Para esto se emplearon métodos etnográficos tales como entrevistas a (...) profundidad a miembros de la asamblea, y el contenido de programas radiales de la emisora del municipio. Como conclusión se plantea que el fortalecimiento de las políticas de identidad se ve influenciado por las redes sociales que intervienen en el proceso. (shrink)

Brian Cutter objected to the consequence argument due to its dependence on the principle that miracle workers are metaphysically impossible. A miracle worker is someone who has the ability to act in a way such that the laws of nature would be violated. While there is something to the thought that agents like us do not have this ability, Cutter claims that there is no compelling reason to regard miracle workers as metaphysically impossible. However, the paper contends that miracle workers (...) are indeed impossible according to well-known theories concerning the laws of nature. This result highlights the reliance of the consequence argument on a plausible premise, which is widely accepted by proponents of non-Humean views of laws. The paper also provides a way to explain away the intuition that miracle workers are possible, but this has the upshot that a recent, two-dimensional formulation of the consequence argument is unsound.

The work of Emmanuel Levinas has been both abundantly recognized and criticized in moral philosophy. This Janus-faced attitude is also present in ecological theories, which find fertile ground in Levinas’ thought without being able to explain its apparent anthropocentrism. Opposing hermeneutical paths tend to focus either on otherness as an absolute alterity, implying a potentially unlimited responsibility for all alterities, or on otherness as a re-foundation of humanism, leading to the conclusion that responsibility is unlimited only among humans. Here I (...) seek to disentangle Levinas from these two extreme interpretations, first by reviewing ecological readings of his philosophy, in both the Francophone and Anglophone spheres, and second by analyzing specific Levinasian terms that might be particularly helpful for a non-anthropocentric or deep ecology. The main results of this investigation are a distinction between the ethics of responsibility and the ethics of vulnerability, an explanation of Levinasian compulsory or methodological humanism, and a schematic model of sensibility as enjoyment/vulnerability capable of supporting deep ecology without the traditional notions of free will, rights, or values.

Reflexión dialéctica sobre las relaciones entre Ilustración y feminismo. Reconoce la herencia ilustrada del feminismo pero subraya cómo la Ilustración contiene también las bases teóricas que definen la sujeción de la mujer, una vez que lo femenino se sitúa en el reino de la naturaleza a dominar, frente al espacio emancipatorio de la razón.

The Uniform Determination of Death Act (UDDA) provides that “an individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead.” We show that the UDDA contains two conflicting interpretations of the phrase “cessation of functions.” By one interpretation, what matters for the determination of death is the cessation of spontaneous functions only, regardless of their generation by artificial means. By the (...) other, what matters is the cessation of both spontaneous and artificially supported functions. Because each UDDA criterion uses a different interpretation, the law is conceptually inconsistent. A single consistent interpretation would lead to the conclusion that conscious individuals whose respiratory and circulatory functions are artificially supported are actually dead, or that individuals whose brain is entirely and irreversibly destroyed may be alive. We explore solutions to mitigate the inconsistency. (shrink)

En este texto se trata de pensar el proyecto que Foucault inició con el análisis de la parrhesía. Se aborda ese problema en relación a otros dos elementos de su obra: la reflexión sobre la función de los intelectuales y sus escritos sobre la noción de crítica. Desde esa perspectiva trataré de mostrar que las investigaciones sobre la parrhesía reflejan el intento de pensar una nueva política de la verdad.

Requiring family authorization for apnea testing subtracts health professionals control over death determination, a procedure that has traditionally been considered a matter of clinical expertise alone. In this commentary, we first provide evidence showing that health professionals’ (HPs) disposition to act on death determination without family’s prior consent could be much lower than that referred to by Berkowitz and Garrett (2020). We hypothesize that HPs may have reservations about their own expertise as regards death, and may thus hesitate to impose (...) their views on patients’ families. We then address the theoretical question of clinical expertise in death determination by distinguishing judgments about facts (e.g., the presence or absence of spontaneous breathing) from interpretations given of these facts (i.e., their meaning for the vital status of an individual). We argue that, while clinicians may claim some expert authority on the former, they hold no particular authority on the latter. (shrink)

Alireza Bagheri supports a policy on organ procurement where individuals could choose their own definition of death between two or more socially accepted alternatives. First, we claim that such a policy, without any criterion to distinguish accepted from acceptable definitions, easily leads to the slippery slope that Bagheri tries to avoid. Second, we suggest that a public discussion about the circumstances under which the dead donor rule could be violated is more productive of social trust than constantly moving the line (...) between life and death.

En el presente ensayo se propone una lectura de la obra Taberna y otros lugares (1969) de Roque Dalton. Se considera que es oportuno pensar la figura del poeta salvadoreño a la luz, no simplemente de los exilios políticos, sino también de la privación (en términos genéricos) de la figura del poeta de sus antiguas funciones en –lo que Ángel Rama denominó– la ciudad letrada. La ciudad modernizada (Rama, 1984) expulsó al poeta de su lugar privilegiado, lo que provoca un (...) trauma y una búsqueda novedosa. En ese contexto, el poeta redefine su voz y la literatura sufre una reterritorialización, es decir, redefine sus márgenes. En América Latina, el problema fue abordado por José Martí que incluso propuso nuevos desafíos a la disciplina (como el problema de la identidad latinoamericana). Se cree que Taberna y otros lugares (1969) retoma estas búsquedas y se arriesga la hipótesis ue, al redefinir su campo, la obra de Dalton puede ser leída no solo en clave literaria, sino también historiográfica desde una mirada benjaminiana.

Information Retrieval systems benefit from the use of long queries containing a large volume of search-relevant information. This situation is not common, as users of such systems tend to use very short and precise queries with few keywords. In this work we propose a modification of the Latent Dirichlet Allocation (LDA) technique using data from the document collection and its vocabulary for a better representation of short queries. Additionally, a study is carried out on how the modification of the proposed (...) LDA weighted vectors increase the performance using relevant documents as feedback. The work shown in this paper is tested using three biomedical corpora (TREC Genomics 2004, TREC Genomics 2005 and OHSUMED) and one legal corpus (FIRE 2017). Results prove that the application of the proposed representation technique, as well as the feedback adjustment, clearly outperforms the baseline methods (BM25 and non-modified LDA). (shrink)

La expansión de las actividades informales de feriantes en el conurbano bonaerense constituye una de las manifestaciones del fenómeno de la heterogeneidad no regulada del aprovisionamiento de bienes de consumo, que a su vez, emergen como intermediarios económicos que atienden a necesidades y demandas de consumidores territorialmente segregados y no articulados a los mercados formales, en su mayoría.Es en ese sentido que el presente artículo quiere rescatar y señalar los componentes centrales que asoman en un proceso que parte con el (...) supuesto de que la confianza constituye un elemento central cuando otras formas que actuarían como garante de las interacciones aparecen débiles, ausentes o no primordiales como garantía de las interacciones sociales, como es el caso de la feria de Solano.

O artigo analisa, a partir sobretudo do pensamento de Hannah Arendt, o desafio que representa para a política “viver junto”. Embora a expressão origine-se com o ensaísta francês Roland Barthes, o objetivo do artigo é quadruplo: (1) apresentar seu fundamento ontológico na condição humana ou existencial de “ser-com”, ou seja, de ser junto aos outros, pensada desde Martin Heidegger; (2) descrever seu sentido político pela conjugação entre isonomia e diferença na forma da pluralidade pela qual cada pessoa pode aparecer singularmente (...) em atos e palavras, de acordo com uma liberdade frente a quaisquer predeterminações; (3) demonstrar como a recente situação da pandemia de Covid-19 radicalizou o impasse de viver junto – e separado – em sociedade, particularmente no caso do Brasil, colocando em relevo uma dimensão coletiva da liberdade pela interdependência entre os seres humanos; e (4) apontar a importância da forma de governo da república, mas também os perigos da sua fragilização nas democracias contemporâneas no que se refere à dificuldade de responder – como viver junto?

We offer a review of some of the most influential views on the status of Reichenbach’s Principle of the Common Cause (PCC) for genuinely indeterministic systems. We first argue that the PCC is properly a conjunction of two distinct claims, one metaphysical and another methodological. Both claims can and have been contested in the literature, but here we simply assume that the metaphysical claim is correct, in order to focus our analysis on the status of the methodological claim. We briefly (...) review the most entrenched or classical positions, including Salmon’s ‘interactive forks’, van Fraassen’s scepticism, and Cartwright’s generalisation of the fork criterion. We then go on to review the results of the ‘Budapest school’ on the existence of formally defined screening-off events for any correlation —by means of the ideas of probability space extensibility and (Reichenbachian common cause) completability. We distinguish the Budapest doctrine clearly from any of the classical conceptions, and thus present an overall framework for discussions of causal inference in quantum mechanics. The framework, however preliminary, is essential work for a thorough assessment of the conditions under which PCC may be a reliable tool for causal inference in a genuinely probabilistic (indeterministic) context.

Desde la ruptura con la visión liberal decimonónica del fenómeno nacionalista, los autores emprenden la difícil tarea de reconstruir, aunque sólo programáticamente, el sentimiento nacionalista desde un punto de vista emancipatorio. Este es el único camino posible para enlazar con los nuevos movimientos sociales que, como el texto señala, generalmente rechazan el fenómeno nacionalista. En efecto, existe ya un nuevo nacionalismo, con un fuerte potencial emancipatorio y que está llamado a caminar junto a la idea de Ecología politica. La ruptura (...) con el nacionalismo decimonónico tiene lugar cuando los nuevos nacionalismos aparecen como un acto de disidencia contra el concepto de Estado-Nación. Este concepto cada vez más afectado por su crisis constitutiva y crónica-crisis de la participación política reducida a"democracia virtual", crisis de eficiencia y crisis cultural-, es el objetivo a combatir por parte de los nuevos nacionalismos. Aquí tiene lugar el encuentro con la Ecología política, en la disidencia del progreso, en la búsqueda de caminos de reconstrucción de identidades destruidas por el mercado. Incluso, la Etnopolítica y la Ecología política coinciden en el mismo campo -el de la disidencia, el de las vías alternativas, el de la emancipación-, con los mismos significados -pluralismo, urgencia vital, necesidad-; finalmente, buscan alcanzar objetivos en los que se coincide: seguridad ontológica y reconstrucción conjunta de las formas de vida ecológicas.

En este artículo se presenta un abordaje general de la teoría de la justicia social de John Rawls. Revisamos algunas críticas desde diversos frentes teóricos. Consideramos que la justicia social permite enjuiciar las consecuencias regresivas para la humanidad del capitalismo en su fase neoliberal y comenzar a imaginar otros mundos posibles.

In the context of business, interactions between individuals generate social systems that emerge anywhere within a corporation or in its relations with external agents. These systems influence the behaviors of individuals and, as a result, the collective actions we usually attribute to corporations. Social systems thus make a difference in processes of action that are often morally evaluated by internal and external agents to the firm. Despite this relevance, social systems have not yet been the object of specific attention in (...) the literature on moral agency in business. To fill this gap, I construct a theoretical framework based on Luhmann’s ideas on social systems and morality. In particular, I argue that morality is a phenomenon that occurs in communication, and an agent can engage in morality in three different ways (as a _moral factor_, an _expressive moral agent_, or a _reflective moral agent_) depending on the functions it plays in communicative interactions. Based on this framework, I argue that social systems in business can be considered moral agents of those types. (shrink)

Este artigo tem como objetivo principal analisar o pensamento desenvolvido por Georges Canguilhem e Gilbert Simondon sobre dois conceitos principais: o conceito de organismo e de máquina. A intenção é de reconstruir, a partir das continuidades e descontinuidades entre os dois conceitos, o raciocínio desenvolvido pelos dois autores sobre esses temas na história da filosofia francesa do século passado. Assim, tomamos como escopo as obras La connaissance de la vie, publicada por Canguilhem em 1952 e a tese complementar de doutoramento (...) de Simondon, orientada por Canguilhem, Du mode d’existence des objets techniques, de 1958. A partir disso, o texto se divide em seis partes: uma introdução, onde damos as especificações de escopo e de análise, seguida pela primeira parte, onde analisamos os conceitos de pensamento, conhecimento, sujeito e objeto. Em seguida, na parte dois, analisamos os conceitos de máquina, mecanismo e motor, como utilizadas em Canguilhem, e os conceitos de indivíduo, elemento e conjunto técnico desenvolvidas por Simondon. A terceira parte se dedica a analisar a questão do autômato, bem como os conceitos de mecanismo e finalismo. A quarta parte desenvolve o conceito de organismo-máquina e os conceitos de potencialidade e de teleologia desenvolvidos principalmente em Canguilhem. Por fim, na conclusão, analisamos as aproximações e distâncias entre os dois autores, bem como a imagem do monstro e do robô. (shrink)

A principios de los años 80 se desató en Francia una polémica conocida como «el silencio de los intelectuales». En este texto abordaremos la singular postura de Michel Foucault al respecto. Para ello realizaremos una doble operación. Por un lado, planteamos la hipótesis siguiente: se pueden encontrar los fundamentos que sostienen su posición en los análisis que realizó sobre la parrhesía a partir de los años 80. En segundo lugar, realizaremos un recorrido por autores como Lyotard y Blanchot, quienes intervinieron (...) en dicha polémica con conocidos escritos, para mostrar las particularidades de la apuesta de Foucault. De esta manera, pretendemos, no solamente mostrar su original aportación al problema, sino señalar los desplazamientos respecto a la crítica del intelectual que había elaborado durante los años 70.

The rise of mathematical developments in the theories of consciousness has led to new measures to detect consciousness in a system. The Integrated Information Theory is one of the best mathematical rooted attempts to quantify the level of consciousness in a system with Φ as the effective information generated in a system above its parts. Recently, the IIT has inspired the Perturbational Complexity Index to detect conscious states in patients with disorders of consciousness, and it has shown to have almost (...) perfect classification accuracy. In this study, we explore the statistical correspondence between the theoretical Φ and the experimental PCI through a neurocomputational model of coupled oscillators that can be artificially perturbed, which mainly focuses on the dynamics of collective synchronization between subsets of brain areas. Our results reveal that both measures are statistically related but, in principle, this relationship is far to be perfect. These results are discussed in the context of the model of coupled oscillators, which mainly focuses on the dynamics of collective synchronization between subsets of brain areas. (shrink)

Este artigo discute como os conceitos de mediação e representação se articulam na reflexão de Carl Schmitt em alguns de seus primeiros escritos e preparam o terreno para a formulação da ideia de representação política em um de seus trabalhos mais conhecidos: Teoria da Constituição. O procedimento mediante o qual se traduz uma realidade amorfa ou um coletivo em forma de representação política se atém à noção de presentificar algo ausente ou tornar visível algo invisível. Toda ideia entra no mundo (...) empírico como hóspede forasteiro e para ganhar existência ou visibilidade necessita de uma decisão soberana pela sua representação. A finalidade deste estudo é explicar o modo pelo qual ocorre este procedimento. (shrink)
