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)

En el ámbito específico de la crítica de las prácticas escénicas en España, el término “artes vivas” ha comenzado a utilizarse ampliamente en los últimos años para referir una serie de prácticas comprendidas hasta entonces bajo la denominación de “teatro posdramático”. En este contexto, el presente escrito tiene el propósito de analizar el debate teórico en torno a dicho desplazamiento terminológico, de gran pregnancia tanto desde un punto de vista académico como desde la perspectiva de la creación artística misma. Con (...) miras a tal fin, el argumento aquí expuesto parte de la definición de “teatro” ofrecida por Hans-Tier Lehman en Postdramatisches Theater para luego discriminar sus puntos de contacto y divergencia con las prácticas comprendidas tradicionalmente bajo el término Live Arts, en un recorrido orientado a reubicar y defender la legitimidad de la expresión “teatro posdramático”.

En este artículo se presenta una revisión bibliográfica de la novela Terra nostra, de Carlos Fuentes, y propicia diálogos que evidencian su actualidad y su relación interdisciplinar con la filosofía, la historia, el arte, la sociedad y la cultura. En los criterios estructurales se distinguen estas temáticas: mito e identidad, relaciones con el otro, imagen y memoria, y la reconstrucción de lo que somos y seremos. Se tuvieron en cuenta franjas temporales de ocho años, desde el momento de su publicación, (...) 1975, hasta el año 2015. Los estudios destacan los problemas de la identidad latinoamericana, la intertextualidad, la multiculturalidad y la conquista; revelan su actualidad en el siglo XXI a través del mestizaje, las tradiciones culturales del Viejo y el Nuevo Mundo, y los otros mundos; y expresan, así, la necesidad de reconstruir un nuevo humanismo.

The space-time expansion has a new perspective on the universe phenomena. In this article, the key features of the Space-Time Expansion Theory are summarized and discussed, with three postulates incorporating different insights into the behavior of space-time expansion, gravity, space-time curvature, and time itself. Gravity is not an attraction; it is a push. Inertia, free fall, the principles of the theory of relativity and some other phenomena support the author’s assertions. The expansion of space-time is universal, occurs everywhere, and produces (...) gravity instead of counteracting it. Being immersed in the same space-time acceleration, we only perceive the disturbance caused by the matter, which is the massive objects push. This study aims to offer scientists an alternative investigation. “Gravitation is not attraction; it’s a push.” All in accordance with hydrodynamic gravitation and expanding Universe. (shrink)

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)

In various parts of the world—of which Mexico is one example— archaeology has been not only an academic discipline but has followed other motivations and goals, some valid and others more disputable: formation of a nationality, a need to know ancient roots, importance of a distinct art for understanding past societies or simply the promotion of tourism by attracting people to visit recently-excavated monuments or those that are already famous. In this paper, I intend to present the case of Mexico.

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)

The Habermasian concept of ‘interest’ has had a profound effect on the characterization of scientific disciplines. Going beyond issues unrelated to the theory itself, intra‐theoretical interest characterizes the specific ways of approaching any science‐related discipline, defining research topics and methodologies. This approach was developed by Jürgen Habermas in relation to empirical–analytical sciences, historical–hermeneutics sciences, and critical sciences; however, he did not make any specific references to health sciences. This article aims to contribute to shaping a general epistemological framework for health (...) sciences, as well as its specific implications for the medical and nursing areas, via an analysis of the basic knowledge interests developed by Habermas.

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.

This paper explores space-time with the Minkowski equation, trying to integrate using the three manuscripts presented to the Open Journal of Philosophy (OJPP) a “new theory of gravity” by introducing the concept of space-time flow. Gravity is a push rather than a pull, an idea presented in the first manuscript. Gravity is the inertia, the shape (frame) of space-time produced by dark energy. The space-time surrounding you provides the force that pushes you upwards, but it doesn’t increase the diameter of (...) the Earth. The sensation of gravity is actually caused by the accelerated flow of space-time against you, which acts as a mirror. The Earth’s expansion is apparent; creates the illusion, but Earth does not expand; rather, the space-time flow emanating from the Earth generates gravity. Einstein’s theory of relativity explains that gravity results from the curvature of space-time caused by the presence of mass and the background dark energy. “Dark energy, introduced from all directions,” which exists throughout the universe in space-time, is responsible for the universe’s accelerated expansion. One way to expand space-time is through the concept of cosmic inflation, which suggests that the universe lives a continuous widening of space-time. Free fall and relativity theory support this claim. Dark energy pushes (pressure) space-time inside the atoms, and the space-time, as in a nozzle, produces an accelerated flow which is gravity. Dark energy floods the whole space and produces positive pressure. It is a non-local/ non-analytical energy, an omnipresent that pervades everything. Dark energy is a space-time property; it was first discovered in 1998. The pressure makes space-time emerge from every point of the Universe and push it expansively. Quantum physics suggests that all the energy in the Universe can form a single universal emergent system, which produces time in the present before us in 4D space-time. This is dark energy. The expansion of space-time is universal and occurs everywhere. When this expansion occurs within atoms, it produces a space-time flux, which is gravity. The general expansion produces it and counteracts it. Pushing space-time outside of Earth (Earth does not expand, just looks like it does) is this space-time flux that makes Earth coordinates move upward, to make it feel like falling into Earth. The apparent matter expansion is its complement mirror. Here, we present Gravity as accelerated space-time flow going out from massive objects. (shrink)

The phenomenal properties of conscious mental states happen to be exclusively accessible from the first-person perspective. Consequently, some philosophers consider their existence to be incompatible with materialist metaphysics. In this paper I criticise one particular argument that is based on the idea that for something to be real it must (at least in principle) be accessible from an intersubjective perspective. I argue that the exclusively subjective access to phenomenal contents can be explained by the very particular nature of the epistemological (...) relation holding between a subject and his own mental states. Accordingly, this subjectivity does not compel us to deny the possibility that phenomenal contents are ontologically objective properties. First, I present the general form of the argument that I will discuss. Second, I show that this argument makes use of a criterion of reality that is not applicable to the case of subjective experience. Third, I discuss a plausible objection and give an argument for rejecting observation models of self-knowledge of phenomenal contents. These models fall prey to the homunculus illusion. (shrink)

An omnipresent, non-local/non-analytical energy that pervades everything enters the Universe through all infinitesimal points. Without determining its origin, our approach is to explain our gravity theory based on Einstein’s relativity theory and the behavior of space-time flow. This influx occurs continuously throughout all of space-time, making the universe expand. Our theory presents two kinds of expansion: (PUE) space-time primary universal expansion and the (VME) virtual matter expansion that occurs with the interaction of space-time with the matter. The internal space-time in (...) atoms produces a virtual slight broadening of the matter’s atoms. From our frame of reference, we can only distinguish the perturbation that occurs to the (PUE) primary universal expansion if it encounters matter. This perturbation finally is restored by a Gaussian distribution at the spherical environment. We call it the (STD) Space-time accelerated displacement. It is the inertial-gravity field. Thus, matter expands by the superposition of atoms (molecules). The accelerated expansion increases proportionally to the number of atoms that radially constitute matter. The effect is manifested immensely increased in the surface of the stellar objects. Then the surface of the massive stellar objects pushes and displaces the object’s external surrounding space-time. The acceleration of the (STD) space-time displacement decreases with the radius squared from the center of mass as it is distributed concentrically. The acceleration we feel at the Earth’s surface is permanently fixed, because when space expands, time also proportionally expands. The associated speed (ds/dt) is immersed in the accelerated expansion of space-time; the time base is the same as the acceleration of the PUE (space-time primary universal expansion) (d2s/dt2). Otherwise, in a short time, this acceleration and its associated velocity would reach the speed of light. Our theory introduces a different concept: “repulsion instead of attraction”. The expansion of space-time produces gravity instead of counteracting it. Finally, we explain using this gravity theory: Earth’s oceans, creating tidal bulges on opposite sides of the planet.

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)

The aim of this paper is to identify literary pictures of everyday life of lower-class Arab-Muslim women in urban contexts in adab books, relating them to the knowledge we have about them through other kinds of sources. The study has been mainly based on Ibn ‘Āṣim’s Ḥadā’iq al-azāhir, an adab work of the Nasrid period. However, in order to provide a broader scope, it has also been imperative to examine other adab books from the pre-modern era, composed in different periods (...) and places. Altogether, we contribute with a number of texts and references not yet used in studies on the subject. Their analysis results in the conclusion that the literary representations contained in their anecdotes confirm the so-far available information on lower-class women, mostly originated from historical sources, as well as from law and ḥisba treatises. The particular interest of these anecdotes lies in the fact that most of their female characters belong to the popular classes and their behaviour in everyday life is clearly depicted throughout their plots. Regarding the physical places in which these women led their lives, in adab prose we can hardly perceive any separation between male and female spaces in the cities. Relevant stories show humble women performing diverse activities outside the domestic sphere and establishing relationships with men from inside and outside their homes. (shrink)

Este artículo trata de una versión novedosa del cuento folclórico ATU 1215 desconocida hasta la fecha para la crítica que se ha ocupado del mismo. Fue transmitida por el erudito iraquí Ibn Ṭāwūs y data del s. XIII. Dicho texto presenta varios puntos de interés: se trata de una de las muestras escritas más antiguas de este cuento folclórico e introduce la novedad de Luqmān como protagonista paterno respecto a las otras dos versiones árabes conocidas de época medieval, inaugurando una (...) transmisión entre intelectuales chiíes que alcanza hasta la actualidad. A lo largo del trabajo, estudiamos las particularidades de esta versión árabe y la ponemos en relación con las demás árabes premodernas conocidas y otras que sacamos a la luz, comparándolas en ciertos aspectos con otras cristianas medievales. Además, tratamos de explicar por qué en algunos casos se ha considerado el cuento una fábula esópica. Por otro lado, prestamos atención a varias versiones orales protagonizadas por Ǧuḥā y su contribución a la difusión oral del cuento en el mundo árabe asociado a un antiguo refrán. Nuestras conclusiones insisten en la relevancia de la versión de Ibn Ṭāwūs, por los motivos mencionados. Además, concluimos que varios de los textos abordados demuestran la difusión del relato en Oriente en el s. XIII, desde donde una versión emparentada con la del escritor iraquí habría llegado a Europa y circulado en ejemplarios de autores cristianos. (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.

Cet article prétend expliquer l'invisibilité relative du conflit armé colombien par rapport à d'autres situations de crise internationale. Au lieu de présupposer que le problème repose sur une faible médiatisation des événements rapportés à la Colombie, il se penche sur les tentatives de mise en sens des événements effectuées par les journalistes au moment de leur médiatisation. L'argument central est que l'opacité du « problème colombien » sur la scène internationale est surtout liée à la difficulté de parvenir à élaborer (...) un récit capable de rendre intelligible ce qui se passe en Colombie.This article tries to explain the relative invisibility of the Colombian armed conflict in relation to other international crisis situations. Instead assume that the problem lies in a low media coverage of events reported to the British, it focuses on the attempts of making sense of the events conducted by journalists at media coverage. The central argument is that the opacity of the "Colombian problem" on the international scene is mainly due to the difficulty of reaching to develop a story that can make sense of what is happening in Colombia.

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.

The present article considers the implications projected by the main characters of Universal History of Infamy by Jorge Luis Borges. The seven protagonists embody a common pattern in their infamous trajectory: they exploit the tools of power by using discourse, according to the proposition by Michel Foucault, despite their being “on the other side of the law”. Although conditioned by specific historical-cultural circumstances, these heroes-antiheroes share the use of evil and the ascent to a seudo-mythical pedestal subsequently to the summit (...) of their infamy. One of the central ideas of the article is that the tension between evil –abjection– and the ascension to the category of myth –sublimation– originates the discharge of the infamy and configures its universal image.
