In many vertebrates, the enzymatic oxidation of dietary yellow carotenoids generates red keto‐carotenoids giving color to ornaments. The oxidase CYP2J19 is here a key effector. Its purported intracellular location suggests a shared biochemical pathway between trait expression and cell functioning. This might guarantee the reliability of red colorations as individual quality signals independent of production costs. We hypothesize that the ornament type (feathers vs. bare parts) and production costs (probably CYP2J19 activity compromising vital functions) could have promoted tissue‐specific gene relocation. (...) We review current avian tissue‐specific CYP2J19 expression data. Among the ten red‐billed species showing CYP2J19 bill expression, only one showed strong hepatic expression. Moreover, a phylogenetically‐controlled analysis of 25 red‐colored species shows that those producing red bare parts are less likely to have strong hepatic CYP2J19 expression than species with only red plumages. Thus, both production costs and shared pathways might have contributed to the evolution of red signals. (shrink)

Explainable artificial intelligence has become a vitally important research field aiming, among other tasks, to justify predictions made by intelligent classifiers automatically learned from data. Importantly, efficiency of automated explanations may be undermined if the end user does not have sufficient domain knowledge or lacks information about the data used for training. To address the issue of effective explanation communication, we propose a novel information-seeking explanatory dialogue game following the most recent requirements to automatically generated explanations. Further, we generalise our (...) dialogue model in form of an explanatory dialogue grammar which makes it applicable to interpretable rule-based classifiers that are enhanced with the capability to provide textual explanations. Finally, we carry out an exploratory user study to validate the corresponding dialogue protocol and analyse the experimental results using insights from process mining and argument analytics. A high number of requests for alternative explanations testifies the need for ensuring diversity in the context of automated explanations. (shrink)

The assembly of products or components by operators in industries is a complex task with recurring problems. In these processes, operators often make errors that can lead to defective products. Therefore, they need to be inspected later to verify their correct assembly. The main problems are caused by several reasons including high employee turnover, lack of experience in manufacturing specific products or confusion in interpreting instructions to assemble similar components. In this paper, a novel structured language aimed to describe the (...) required actions to manufacture a product in industrial assembly environments is presented. The main contribution is to provide a formal language to feed automatic systems that can verify through visual control whether the actions performed by the operator are carried out following the standard described by this language. In general, the use of this formal language will allow to minimize the negative impact of errors during assembly and to reduce waste in many forms in the industry. (shrink)

The World Health Organization, in its last review of its International Classification of Diseases, established a new classification for chronic pain. Among the principal categories, of particular interest is chronic primary pain as a new type of diagnosis in those cases in which the etiology of the disease is not clear, being termed as chronic primary visceral pain when it is situated in the thorax, abdomen, or pelvis. Due to the novelty of the term, the objective of the systematic review (...) was to examine the psychopathological and neuropsychological disorders associated with chronic primary visceral pain. We carried out a search of the scientific literature following the PRISMA directives using the Pubmed, Medline, PsycInfo and Scopus databases. A total of 33 articles were selected after applying the inclusion and exclusion criteria. The analysis of the studies showed that most persons with chronic primary visceral pain suffer from at least one psychological disorder; the most prevalent being anxiety, depressive or somatoform disorders. The most frequent psychopathological symptoms are anxiety, depression and somatization. Similarly, the findings are insufficient to determine the existence of deficits in the domains of executive functioning, memory and intelligence. However, the existence of attention biases does seem to be clear. This review supposes a starting point for conceptualizing chronic primary visceral pain. It is necessary to continue further research so as to obtain a better understanding of this pathology and the disorders associated. (shrink)

Resumen Este artículo estudia la relación de Alejandro Magno con los elefantes, tanto desde el punto de vista militar como simbólico. Opera con el concepto de zoología de la realeza, analizando el status y jerarquía de caballos, águilas, leones, elefantes y dromedarios en la nueva ideología del conquistador macedonio.

En este trabajo sobre los pensadores novohispanos Alonso de la Veracruz y Tomás de Mercado se seguirá la argumentación de un tema escasamente explorado: el papel fundacional de la ley natural y su interpretabilidad a través de la ley humana. Se mostrará que ambos autores, basados en las tradiciones salamantinas del siglo XVI, introducen un método que afirmaría la validez de la ley natural y, al mismo tiempo, permitir aplicaciones diversas de los parámetros normativos de la ley humana. Esto (...) es posible, como lo sostiene Veracruz en su crítica al diezmo para los pueblos indígenas, cuando la ley natural tenga que reinterpretarse a partir de hechos sociales concretos o cuando, como en el caso de Mercado, la ley humana sea congruente con la ley natural y, no obstante, tenga que desacatarse para evitar perjuicios personales o públicos en el plano comercial.

«Obra en Blanco» es un libro sobre la obra temprana de Julio Enrique Blanco de la Rosa (1890-1986), un olvido más en la historia de la filosofía colombiana. Salvo en notas al margen, a Blanco no se lo encuentra en los estudios sobre la historia de la filosofía. Algunos han atribuido su desconocimiento a la incomprensión de un medio que no supo de su genialidad, otros creen que se debe a que su filosofía fue una necedad que consistió en poner (...) nuevos nombres a las viejas cosas. «Obra en Blanco» no intenta defender su genialidad o censurar a quienes lo han acusado de necedad: analiza y presenta una selección de un periodo juvenil de su obra, comprendido entre 1909-1920. Con ello sólo se busca aportar a la construcción de una historia de la filosofía nacional, y alimentar la discusión sobre la historia de la contribución filosófica de un hombre, cuyas páginas se encuentran aún en blanco.

Compuesto por capítulos de diferentes especialistas en los estudios literarios que laboran en universidades de México, Europa y Estados Unidos, el libro Literatura aplicada en el siglo XXI: ideas y prácticas es el resultado de una invitación y de un esfuerzo para reflexionar sobre las posibilidades epistémicas del fenómeno literario como creación, recreación y programación. Parte de cuestionarse si el binomio clásico de estudiar/aprender ha perdido su sentido en la era de la tecnificación cibernética, es decir, de la inteligencia artificial (...) y de la paulatina robotización del mundo. Puesto que los algoritmos ya leen y escriben automáticamente, y son capaces de combinaciones y hasta de generar narrativas, nos pareció necesaria una mayor sensibilización de la palabra consciente. Una reflexión de la educación poética para diferenciarnos de las máquinas y también para entender su funcionamiento, así como reestablecer la reflexión o diálogo de los creadores con los críticos, y de los promotores de lectura con los teóricos de la lectura. Tal restablecimiento debería ser el desafío de los estudios literarios (universitariamente entendidos) en lo que resta del siglo XXI. De esta forma, los ensayos aquí reunidos hacen referencia a autores y obras del siglo XX y aun de otras centurias, pero con la intención de reflexionar sobre su aplicación en lo que va del presente siglo.

For the philosopher of Rotterdam, religious coercion has two essential sources of illegitimacy: the linking of religious and ecclesiastical belief and the use of politics for religious purposes. Bayle responds to it, with his doctrine of freedom of conscience, on one hand and by means of the essential distinction between voluntary religious affiliation and political obligation, on the other hand. From my perspective, his doctrine of tolerance does not involve an atheist state, nor does it mean the rejection of the (...) presence of religion in the public space or its displacement to the intimate sphere of the conscience. This paper proposes a reading of Baylean tolerance as a political doctrine that allows the articulation between freedom of conscience, minority confessions, and official religion. Thus, the Baylean theoretical model could be considered a proposal to provide a normative form to the practice of toleration present in the seventeenth -century Netherlands. (shrink)

Este texto se propone la lectura de la novela Pedro Páramo a la luz de algunos de los conceptos que, a fin de caracterizar la hermenéutica literaria, y la teoría de la interpretación, elabora Paul Ricoeur en su texto Teoría de la argumentación. La primera parte consiste en una breve presentación de los mismos y la segunda en la lectura a Epicuro, filósofo perteneciente a la época helenística, presentó en su ética una visión racional acerca de la muerte, criticando por (...) ello el carácter irracional con que es vista por la mayoría de los hombres. De este modo, el filósofo argumenta que es necesario que el hombre se aleje del dolor por medio del placer y así conseguir la felicidad y la plenitud de la vida, y que igualmente debe evitar el temor a la muerte, ya que éste implicaría la pérdida del placer y la inclemente disminución de opciones para obtener la vida feliz. Paralelamente a Epicuro, Schopenhauer da claras muestras de semejanza con el filósofo griego en el tratamiento que le da al tema de la muerte en su filosofía. (shrink)

El pensamiento ambiental, de tipología mesiánica, se caracteriza por el relativismo culturalista y el escepticismo autoritario en la fe y el mito de la naturaleza, y de un ser metafísico o religioso, que se introduce de forma simbólica, ya sea de manera inmanente o trascendente en las configuraciones simbólicas y por ende en las acciones. Es característico de dicho mesianismo su auto presentación en contra de la tecnología; sin diferenciar críticamente ciencia de técnica, y ambas categorías del instrumentalismo cosificante. Esta (...) corriente de mesianismo ambiental transforma las visiones críticas de las teoría de la acción comunicativa colocándolas acríticamente sobre la plataforma ideológica de la teología de la liberación latinoamericana, con un centramiento metafísico y antropológico, que se denominará para los propósitos argumentativos de este articulo: teología de la acción comunicativa.

This dissertation proposes the central elements of a Social Enactive Theory of Perception. According to SEP, perception consists in sensory-based practices of interaction with objects, events, and states of affairs that are socially constituted. I oppose the representational view that perception is an indirect contact with the world, consists of the passive receiving and processing of sensory input, is in need of constant assessment of accuracy, and is a matter of individuals alone. I share the basic enactivist insight that perception (...) is a type of activity, but I depart from standard enactivism on the grounds of its individualistic bias and its limited conception of activity. Instead of motor actions, I formulate the concept of perceptual practices as the appropriate framework to understand perception. Perception is woven into socially informed, contextual, sensory-based everyday activities, such as food, dance, and dress, and even seemingly independent, basic perceptual activities and concepts are constituted by such practices. Perceptual individual interactions instantiate social perceptual practices but are not just repetitions of a script. We perceive objects in virtue of perspectives or appearances, not in spite of them, and on this basis I offer SEPâs take on experience, properties, and contents. I conceive perceptual experience as finely grained interactions between subjects and objects, both of which are spatially, temporally, and pragmatically situated. Objects and their sensory properties are perceived dynamically and always in multiple appearances. Perceptual content offers a pragmatic specification of the perceptual objects in the specific ways they appear to subjects. For SEP, perception is normatively structured. SEPâs perceptual normativity is not a worry about a supposed constant threat that our perceptions be nonveridical, but about the placement of perceptual things in a system of possibilities and expectations, cast in terms of degrees of fulfillment of expectations and in a horizon of pragmatic significance, both of which are functions of the socially constituted interactions between a perceiver and a rich theory of appearances.

This paper is intended to investigate the role of Venture-Capital Syndication background in the relationship between intellectual capital and portfolio firm performance ; specifically, this article examines the moderating effect of VCS’s leading firm background and member heterogeneity on the effect of IC on PFP. This study used a modified VAIC model to measure IC to compose a 4-component variable including human capital, structural capital, relational capital, and innovation capital. The data were collected from VCS-backed and listed firms in China (...) during 2014 to 2018 applying the pooled OLS model for hypotheses test, Generalized Method of Moments to reduce endogeneity and unobserved factor control, and also return on equity instead of ROA for the robustness test. Empirical results showed that IC and its components can improve PFP for VCS-backed firms in China; in detail, IC showed greater impact on performance of firms invested by foreign lead investors than in private or government VCS, specially reflected in the impact of innovation capital on PFP. Furthermore, IC showed weaker impact on PFP of mixed VCS-backed firms compared to pure VCS-backed firms and showed diminished effect on higher VCS member heterogeneity mainly reflected in the impact of relational capital on firm performance. These findings propose a new way of combining IC and VC to improve firm performance and are beneficial to theoretical development of IC and VC as well as a perspective for VC firm managers to choose suitable partners prior to join a VCS.

The literary genesis of Einbahnstraße by Walter Benjamin represents a very special case of the use of the procedures of surrealism in the philosophical-literary production of the author. The process of evolution of thinking that ended up in the writing of this piece is unveiled throughout the present analysis. This is a sign of both waiver and restart; the opening for a new productive dimension in the career of one of the most important —and misunderstood— philosophers of the 20th century. (...) More than enlightening a small master piece of philosophy from a literary perspective, or analyzing a small master piece of literature from the philosophy, what is being problematized here is the division, cultivated or figured throughout the years, between both disciplines. This work is intended to recover what is insoluble from the philosophical-literary labor of Walter Benjamin, besides tracing a possible reconfiguration for an interdisciplinary field of work to come up and contribute in the understanding of the problem called The Retreat of Metaphor by Jacques Derrida.

Este artículo se propone examinar la historia de la recepción inicial de las vanguardias históricas en la literatura hispanoamericana a través de la obra de Alfonso Reyes. Sin ignorar el estallido de la Revolución Mexicana y de la Primera Guerra Mundial, el futurismo y el cubismo responden a la praxis cotidiana relacionada con el belicismo. Ambos pueden encontrarse en otros textos de Reyes escritos entre 1914 y 1924 en Madrid, donde él se había autoexiliado. Este ensayo termina comparando el vanguardismo (...) inicial de Reyes con el de Borges y Huidobro. (shrink)

La verdad, entendida por Tomás de Aquino como la adecuación entre el intelecto y la realidad, forma, en aquel que la busca y la dice, una virtud moral denominada veracidad. Dicha comprensión de la verdad, epistemológica y moral, inspira una manera de entender tanto la pedagogía como la responsabilidad social universitarias. Este artículo desarrolla las relaciones entre epistemología realista, virtud moral y universidad, y muestra cómo la noción de veracidad ha servido de inspiración para las apuestas pedagógicas de la Universidad (...)

Here they are revised notions of the Western tradition that conform the discourse of poetic reason, and the way that Maria Zambrano assumed them. Her thought examines the possibilities of the words, either poetic or philosophical, to allow persons to get conscience. She attempts to unify both types of words using a notion of love as essential intent for dealing with the otherness, allowing, also, the human being conscious reflection on the affectivity. To achieve this, she revises culture to find (...) ideas and examples to support the poetic reason as loving and hopeful reflection and as a possibility of the humanity to know about its own feelings.

Localized mRNA translation is a biological process that allows mRNA to be translated on‐site, which is proposed to provide fine control in protein regulation, both spatially and temporally within a cell. We recently reported that Vasa, an RNA‐helicase, is a promising factor that appears to regulate this process on the spindle during the embryonic development of the sea urchin, yet the detailed roles and functional mechanisms of Vasa in this process are still largely unknown. In this review article, to elucidate (...) these remaining questions, we first summarize the prior knowledge and our recent findings in the area of Vasa research and further discuss how Vasa may function in localized mRNA translation, contributing to efficient protein regulation during rapid embryogenesis and cancer cell regulation.

En el presente artículo se abordarán las relaciones entre Nietzsche y Platón, y Nietzsche y Darwin, a partir de las respectivas autocalificaciones nietzscheanas –a saber, su propia filosofía como ‘platonismo invertido’, y su postura ‘anti-Darwin’. A partir de esto, se buscará alcanzar tres objetivos: en primer lugar, establecer que la calificación nietzscheana de ‘Anti-Darwin’ no se sustenta ni en una oposición de tipo ontobiológico, ni en oposición a un carácter teleológico de algún tipo, sino, principalmente, en una ruptura axiológica; en (...) segundo lugar, mostrar la conexión entre la perspectiva nietzscheana y el platonismo, en divergencia con las perspectivas que, o ponen a Nietzsche en completa oposición al platonismo, o encuentran concordancia no con el platonismo, sino con Platón, o hallan plena continuidad entre uno y otro –el ‘Nietzsche metafísico’ heideggeriano. Finalmente, el tercer objetivo consistirá en mostrar que ambas autocalificaciones se hallan estructuralmente asociadas, es decir, que una no es completamente comprensible sin la otra. (shrink)

The thought of Pierre Klossowski, praised by Foucault, Blanchot, Deleuze, has been scarcely addressed by the philosophical community. We argue in this article that this is largely due to the frequent difficulty of understanding his work as a whole: both his artistic and literary production and his interpretations of Nietzsche or Sade form a coherent whole, whose significance has a deeply critical political scope. The notion of unproductive spending, which occupies a central place in Bataille's work, will be rearticulated in (...) Klossowski's reflections through the concepts of drive, phantasm, simulacrum, value and consumption. In The Living Currency, the political dimension of these terms appears clearly: relying on a rereading of Fourier and Sade, the author shows the extreme degree of deformation of what we assume as a reality in modern industrial society. In this sense, his thinking takes on special relevance today, as a revelation of the excess and unhingedness of a society in which production and consumption are reproduced without limit through the infinite reflections produced by the game between drives, ghosts and simulacra.

In the last few decades, the study of terminology has undergone a cognitive shift that has led to the development of several approaches that study the social, linguistic, and cognitive dimension of terms, such as Communicative Theory of Terminology (CTT) and Frame-Based Terminology (FBT). CTT was developed in the early 1990s and argues that the study of terminology should be based on a communicative perspective, taking into account aspects such as the communicators and the context of communication. FBT has been (...) developed from 2007 and uses certain aspects of Frame Semantics to conceptualise specialised domains and create non-language-specific representations through the analysis of the domain event and on the study of the behaviour of the terminological units in texts. The two theories share many of the same premises and propose the representation of the concepts of a domain in an ontology. FBT also proposes a representation in frames. We explore how these two methods of domain representation can be used to represent the terminology of the domain of seafood in Germany and Spain. (shrink)

In a recent issue of the Journal of Business Ethics, Filipe M. Santos posits that social entrepreneurs maximize not on value capture, but on value creation, only satisficing on value capture to fuel operations, reinvesting in growth, whatever the specific combination of institutional means is deemed appropriate. No doubt the analytical framework of value creation and value capture casts new light on the phenomenon of social entrepreneurship, but we think Santos is asking too much by advocating a shift in focus (...) away from the organization. On the contrary, we maintain that by refocusing the theory on the organizational level and away from the system it is possible to understand that not all organizational solutions available to social entrepreneurs are able to create value and not all value capture strategies can serve a social goal. Indeed, there is only one form of organization that fulfills the criteria of maximizing on value creation, while satisficing on value capture and that is the social enterprise. (shrink)

Citizenship regimes are institutionalized systems of formal and informal norms that define access to membership, as well as associated rights and duties. This paper studies illegalized migration as one of the major tests to assess whether citizenship regimes are fair institutions, based on a historical analysis of legislation meant to reduce illegalized migration in the United States between 1995 and 2022. We build our empirical research starting from a simple observation: despite the great number of bills introduced to reduce illegalized (...) migration to the US, most of such initiatives fail to become law. In fact, 93.5% of all immigration initiatives did not even pass the chamber of Congress in which they were originally presented. Such a high rate of failure shows that these proposals are motivated by electoral aspirations, rather than coming from a genuine wish to help migrants or grant them citizenship. Furthermore, there is also an economic interest that justifies the maintenance of low-cost disposable immigrant labor, with no right to citizenship. Our analysis is an example of how state regulation processes seem to work to formalize, rather than alleviate or eradicate, the precarious legal statuses of illegalized migrants. We conclude that a globalized phenomenon such as citizenship requires going beyond merely institutional and formal conceptions. We need to rethink the institutional notion of citizenship, as a merely status held under the authority of a state and consider it from a cosmopolitan perspective and a multilateral basis. But as long as citizenship remains under the responsibility of states, illegalized migrants will continue to experience precarious citizenship. (shrink)

For most interpreters of the philosopher from Rotterdam, his political doctrine is solely a consequence of his religious and moral doctrines, and so an image of Bayle as a political philosopher is not usually presented. To my mind, however, only by analyzing his political doctrine can the extent of his religious proposal be understood. In this article, I intend to show that both the Baylean criticism of popular sovereignty and his rejection of the right of resistance are analyses that are (...) indissociable from the Baylean doctrine of tolerance. The protection of individual freedom of conscience and the defense of a multi-confessional state model, tolerant regarding religious minorities, can only be articulated as historical reality if they rest on the political doctrine of indivisible sovereignty and on the strictest separation between political obedience and religious membership.

This article considers for the first time the progressive Portuguese periodicals A Voz Feminina and O Progresso from a transnational perspective, with particular reference to contemporary debates about women’s suffrage in England as well as the wider emergence of transnational women’s networks around that time. It discusses the epistolary contact of the Principal Editor, Francisca Wood, with key radical figures such as Lydia Becker in England, Marie Goegg in Switzerland and André Léo in France, through an analysis of relevant editorials, (...) articles and correspondence received from abroad and published in the pages of the journals. Furthermore, it casts light on how Francisca Wood and her enlightened husband, William Thorold Wood, invoked the ongoing support of prominent men such as John Stuart Mill for the cause of women’s rights. Such a pioneer early feminism in Portugal was particularly remarkable in the 1860s – a context preceding the socio-political and cultural debates staged publicly in the 1871 Casino Lectures by the “Geração de 70” – which, furthermore, all but sidelined the “Woman Question.” The article concludes with a brief discussion of whether, notwithstanding Wood’s invisibility at the point of her death in 1900, she may have been behind a symbolically significant cultural intervention: the first translation of Jane Eyre into Portuguese, published in instalments from 1877 onwards in O Zoophilo.

RESUMEN En el presente trabajo se buscará dar cuenta diagramáticamente del alcance y extensión del concepto de vida en Freud y Nietzsche, al pensar sus límites en términos de polos -instancias no alcanzables vitalmente, que marcan la frontera a partir de la cual se extiende el ‘más allá’ de la vida. Dicho de otro modo: haciendo uso de un diagrama, se buscará dar cuenta del carácter de lo vital para Nietzsche - al pensar a la vida como Wille zur Macht (...) - y Freud - desde su último modelo pulsional - no solo en cuanto a su particularidad, sino en función de lo que resulta en cada caso el límite mismo de la vida - es decir, aquello que marca el pasaje a otra cosa que la vida. ABSTRACT In the present work, we will seek to give a diagrammatic account of the scope and extension of the concept of life in Freud and Nietzsche, by thinking about its limits in terms of poles - vitally unreachable instances, which mark the border from which the ‘beyond ‘of life extends itself. In other words: making use of a diagram, we will seek to account for the character of what is vital for Nietzsche - thinking of life as Wille zur Macht - and Freud - from their latest drive model - not only in terms of their particularity, but rather as a function of what the very limit of life results in each case - it means, that which marks the passage to something other than life.
