Dysfunctions of the neural circuits that implement social behavior are necessary but not a sufficient condition to develop schizophrenia. We propose that schizophrenia represents a disease of general connectivity that impairs not only the “social brain” networks, but also different neural circuits related with higher cognitive and perceptual functions. We discuss possible mechanisms and evolutionary considerations.

We commend Arbib for his original proposal that a mirror neuron system may have participated in language origins. However, in our view he proposes a complex evolutionary scenario that could be more parsimonious. We see no necessity to propose a hand-based signing stage as ancestral to vocal communication. The prefrontal system involved in human speech may have its precursors in the monkey's inferior frontal cortical domain, which is responsive to vocalizations and is related to laryngeal control.

Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between goal-directed and stimulus-driven factors. However, the neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress can modulate brain rhythms during an attentional task and a task-free period. We recorded the EEG and ECG activity of 42 healthy participants subjected to either the Trier Social Stress Test, a controlled procedure to (...) induce stress, or a comparable control protocol, flanked by an attentional task, a 90 s of task-free period and a state of anxiety questionnaire. We observed that psychosocial stress induced an increase in heart rate, self-reported anxiety, and alpha power synchronization. Also, psychosocial stress evoked a relative beta power increase during correct trials of the attentional task, which correlates positively with anxiety and heart rate increase, and inversely with attentional accuracy. These results suggest that psychosocial stress affects performance by redirecting attentional resources toward internal threat-related thoughts. An increment of endogenous top-down modulation reflected an increased beta-band activity that may serve as a compensatory mechanism to redirect attentional resources toward the ongoing task. The data obtained here may contribute to designing new ways of clinical management of the human stress response in the future and could help to minimize the damaging effects of persistent stressful experiences.

Jair Bolsonaro, the current President of Brazil, has made himself into one of the most influent advocates of COVID-19 denial. His health policy and his political doctrine are partly based on an implicit moral claim, which is neglected by contemporary political theory. Bolsonarism’s rhetoric raises a moral claim to freedom without responsibility, which relieves its followers from the burdens that emerge from liberal accounts of liberty or from basic goods accepted in a political community. In opposition to liberal or communitarian (...) accounts, Bolsonarism endorses a Hobbesian concept of freedom that describes it as the absence of ‘impediments to motion’. Nonetheless, it differs from Hobbes because it treats this liberty as endowed with moral value and non-negotiable through a social contract. (shrink)

Para el historiador mexicano Edmundo O’Gorman la reflexión filosófica se constituyó en un arma o en un instrumento, cuya eficacia y necesidad surgieron de la lectura de diversas interpretaciones de los procesos históricos y de las meditaciones acerca de su naturaleza y su sentido. En su juventud O’Gorman se entusiasmó por el historicismo, pero posteriormente prefirió no adscribirse a una corriente o escuela específica sino a una tradición. Para O’Gorman, Vico forma parte del linaje de los historiadores a quienes no (...) interesa la historia comprobada sino la historia comprendida, no la constatación rigurosa de los hechos, sino su articulación en la dinámica global del pensamiento. Por eso ambos tienen coincidencias en sus reflexiones sobre la naturaleza del conocimiento histórico, la función de la imaginación, los métodos para entender la diversidad cultural y, sobre todo, el problema de aprehender una “universalidad racional” que no se limite al orden técnico–instrumental.PALABRAS CLAVE: Vico, Edmundo O’Gorman, historicismo, historia, pensamiento hispánico.According to the Mexican historian Edmundo O’Gorman, philosophical reflection was constituted as an arm, or as an instrument, which’s efficacy and necessity emerged from different interpretations of historical processes, and from meditations as to its nature and meaning. In his youth, O’Gorman was enthusiastic about historicism, but later we preferred not to be ascribed to any specific trend or school, but to a tradition. O’Gorman considers Vico as one of those historians who are not interested in history as something to be checked, but as something to be understood; not in the rigorous confirmation of facts, but in its articulation in the global dynamics of thought. Therefore, there are coincidences in their reflections on the nature of historical knowledge, the function of imagination, the methods to understand cultural diversity and, mainly, theproblem of getting an ‘universal rationality’ which would not be limited to the technical or instrumental order.KEYWORDS: Vico, Edmundo O’Gorman, historicism, history, Hispanic thought.

The thought of Nicolás Gómez Dávila is a great absent in the academic atmosphere of our Nation. This article’s intention is to present its principal assumptions, to measure its argumentative richness that could back up a true philosophical thought in our land. To revise his personal opinions in regards to different issues, such as his critique of democracy, modern rationality, Christianity, among others, might help us as an excuse to read a scholar that, though did not leave an immense production, (...) wrote a most interesting series of annotations and texts, that could appeal to every person interested in knowledge. Through his writings, there can be observed the critical view of a man that was raised in tradition: Philosopher, Christian, polyglot, a self-confessed reactionary. However, there is too a tinge of innovation, that turns his reading into something passionate. Thus, Gómez Dávila challenges his reader to know more, from the exquisiteness of his language he tempts the reader to discover even more... from his annotation he suggests the novelty, based in the tradition of thought of which he is extremely familiar with.

Proponer la existencia de filosofía en América Latina se convierte para muchos en un problema. Más dificultades se generarán ahora al proponer la existencia de una estética latinoamericana, teniendo como representante a un pensador colombiano: Nicolás Gómez Dávila. En medio de la obra de este pensador logramos entresacar una serie de códigos estéticos que, si bien están heredados de las concepciones europeas de la estética, podrían darnos atisbos de una mirada distinta otorgada por la observación de objetos y hechos generados (...) por el mestizaje sucedido en medio de tierras fértiles, agrestes y exuberantes como las de nuestra geografía. Realizar esta presentación implica repasar un legado existente, pero olvidado, por lo que actualizar una experiencia filosófica rica que, aunque presente, no se ha manifestado en nuestro medio de manera suficiente. Como objetivos principales de este ejercicio investigativo están: argumentar a favor del ejercicio filosófico realizado en Latinoamérica;proponer el ejercicio aforístico de Gómez Dávila como una aportación colombiana en torno a la estética filosófica; y repasar algunos tópicos estéticos que queremos entresacar en la obra de este autor para realizar un ejercicio hermenéutico de los mismos. Con este trabajo se espera alcanzar no solamente ecos en nuestro medio sino en las distintas latitudes donde ya el autor es reconocido, pero ahora desde la estética. La metodología empleada en esta investigación es realizada desde un ejercicio hermenéutico, en la perspectiva gadameriana. Esperamos proponer, como resultado principal, argumentos que corroboren las aportaciones de Gómez Dávila a la estética desde una perspectiva latinoamericana. Finalmente, concluimos que la estética de Gómez Dávila es de estilo clásicocon vínculos metafísicos, asociada a un canon griego y con una clara perspectiva cristiana, pero que ha sido elaborada por una mente perteneciente a un contexto latinoamericano, del cual no debemos extraer de ningún modo.AbstractTo suggest the existence of philosophy in Latin America becomes a problem for many. Even more difficulties are generated by proposing the existence of a Latin American Aesthetics, having as its representative a Colombian thinker: Nicolás Gómez Dávila. In the midst of this thinker’s work, we were able to identify a series of aesthetic codes which, although inherited from the European concepts of aesthetics, could give us glimpses of a different perspective given by the observation of objects and events generated by the miscegenation that took place in the midst of lush, rugged and fertile lands as those of our geography. To attempt his presentation involves reviewing an existing but forgotten legacy, and updating a rich philosophical experience that, although present, does not manifest in our environment sufficiently. The objectives of this research are: arguing for the philosophy made in Latin America; propose the aphoristic exercise of Gómez Dávila as a Colombian contribution to the field of aesthetics; and review some aesthetic issues that we want to conclude in the work of this author to conduct a hermeneutic exercise thereof. With this paper I expect to reach not only echoes in our philosophical community but in also in other latitudes where Gomez-Davila is already recognized, but now fromthe point of view of aesthetics. The methodology used in this research entailed a hermeneutic exercise, in the perspective of Gadamer. We propose some arguments supporting the contributions of Gómez-Dávila aesthetics from a Latin American perspective. Finally, we conclude that the aesthetics of Gómez-Dávila is of a classic style with metaphysical links, associated with a Greek canon and with a clear Christian perspective, but that it has been developed by a mind that belongs to a Latin American context, from which we cannot intend to separate it in any way.

Different constructions of BL-chains are compared. We establish when the ordinal sum and the poset product of the same family of BL-chains coincide. We also compare the poset product of MV-chains and product chains with saturated BL-chains.

Research based on traditional linear techniques has yet not been able to clearly identify the role of cognitive skills in reading problems, presumably because the process of reading and the factors that are associated with reading reside within a system of multiple interacting and moderating factors that cannot be captured within traditional statistical models. If cognitive skills are indeed indicative of reading problems, the relatively new nonlinear techniques of machine learning should make better predictions. The aim of the present study (...) was to investigate whether cognitive factors play any role in reading skill, questioning the extent to what cognitive skills are indicative of present reading level, and the extent to what cognitive skills are indicative of future reading progress. In three studies with varying groups of participants, the results of four supervised machine learning techniques were compared to the traditional General Linear Models technique. Results of all models appeared to be comparable, producing poor to acceptable results, which are however inadequate for making a thorough prediction of reading development. Assumably, cognitive skills are not predictive of reading problems, although they do correlate with one another. This insight has consequences for scientific theories of reading development, as well as for the prevention and remediation of reading difficulties. (shrink)

_ Source: _Volume 56, Issue 3-4, pp 222 - 240 In medieval theories of consequence, we encounter several criteria of validity. One of these is known as the containment criterion: a consequence is valid when the consequent is contained or understood in the antecedent. The containment criterion was formulated most frequently in the thirteenth and fourteenth centuries, but it can be found in earlier writings as well. In _The Tradition of the Topics in the Middle Ages_, N.J. Green-Pedersen claimed that (...) this criterion originated with Boethius. In this article, the author shows that a notion of containment is indeed present in Boethius, but is not used to define or describe the relation between antecedent and consequent, i.e., the relation of consequence, as Green-Pedersen asserted. The author then offers two interpretations of the notion of containment that are present in Boethius – a metaphysical and a semantic interpretation – and shows how these relate to the containment criterion.

Asylum-seeking and refugee women (ASRW) are population groups characterized by diverse social, economic and legal backgrounds as well as diverse needs. Their backgrounds of forced migration have a profound impact on their overall health, including their sexual and reproductive health (SRH). In Europe, the SRH needs of ASRW are usually more pressing than those of the host country population. In the context of refugee health, it is important to distinguish between asylum seekers and statutory refugees, as asylum seekers have distinct (...) needs and often limited rights in their host country. Yet both groups face many barriers in accessing national health services. This article addresses the issue of entitlements to health services for asylum-seeking women in Europe, and highlights the wide range of difficulties of both asylum-seeking and refugee women in accessing (sexual and reproductive) health services.

How does one make sense of a naked prophet who walked the streets of Jerusalem for no less than three years? This contribution interpreted the ambulatory naked prophet in Isaiah 20 as a sign-act by means of symbolic interactionism and performative interpretation according to which symbolic or sign-acts are multivalent entities. Isaiah 20 was interpreted as an embodied, multivalent text that invited ongoing appropriation among subsequent audiences while exploring the potential meaning of the initial act within the parameters of text (...) and context. It is presupposed that human beings reinterpret symbolic acts in different subsequent contexts and that a symbolic act should never be reduced to one single meaning – this reinterpretation process is illustrated by the Septuagint translation of Isaiah 20. Furthermore, the question will be posed how one could interpret and appropriate a disruptive and ‘foolish’ prophetic and symbolic act of public exposure – Isaiah as an ‘agent provocateur’?Contribution: The performative critique of Isaiah 20 drew attention to the neglected multivalent character of the initial sign-act that enabled ongoing appropriations in new contexts of competing power relations. At first the sign-act was relevant for its pre-exilic audience, then for the post-exilic and even later for a Hellenistic audience by means of the Septuagint version. It also illustrated that text interpretation can be a catalyst that unsettles and disrupts power, even when it is considered folly. (shrink)

In Christian tradition, the name of the Biblical Thomas is connected primarily to the story of John 20: 27 in which the apostle in invited by Jesus to touch his tortured body. This invitation is the result of Thomas’ prior scepticism to the reality of the resurrection. Contrary to popular belief, the text of John does not indicate clearly if Thomas accepts Jesus’ offer. John creates a narrative gap for the readers to fill in, stimulating the reader to contemplate the (...) relationship between the notion of seeing, touching and believing, and their mutual dependency. In this historical-literary article, the author investigates this literary dependency in the synoptic gospels, John’s gospel, several apocryphal texts, and four famous paintings, all focussing on the character of Thomas, in search of the different ways in which these authors and artists try to fill in John’s apparent narrative gap.

Scientific theories are pure theoretical models integrated by a categorical scaffolding. Marx built a pure theoretical model that he called the capitalist mode of production; the historicity of its categories expresses the modes of production from which the capitalist comes and others that followed different paths. It also implies the existence of social formations in which a dominant mode of production and dominated forms of production coexist. The agrarian community is the highest form reached in the community entity and from (...) it comes the peasant economic unit generated in the parcelling of the land during the ancient form and gestation of capitalism, which is why the construction of a peasant mode of production does not proceed.
