A partir del concepto de hospitalidad propuesto por el filósofo francés Jacques Derrida, este ensayo pretende definir los rasgos más significativos de La cresta de Ilión (Tusquets, 2002), de la escritora mexicana Cristina Rivera Garza; novela recientemente reeditada (Random House, 2018) y que resulta pieza fundamental de su narrativa, ya que desde allí se irradiarán muchos asuntos singulares para sus obras posteriores. Si en Nadie me verá llorar (1999), primera novela de Rivera Garza, buena parte de las acciones acontecían en (...) un recinto «hospitalario», La cresta de Ilión parece presentar cierta continuidad, al menos en lo que se refiere a los espacios de desenvolvimiento de la trama y a los personajes masculinos abrumados, pero el efecto performativo sobre la prosa misma de Rivera Garza se verá completamente transformado. Por lo tanto, en diálogo y en polémica con esa crítica literaria anterior que ha trabajado este libro, se estudiará de qué manera un espacio literario recibe, de forma problemática, trazas de otros discursos, pensando este procedimiento de un modo alternativo al «intertexto», concepto que ya parece insuficiente para determinar el articulado de novelas como ésta.

Las aminas biógenas son compuestos nitrogenados de pequeño tamaño con actividad biológica que se forman por la descarboxilación enzimática de ciertos aminoácidos. Las aminas biógenas se encuentran presentes en todos los seres vivos, en los que participan en procesos biológicas de gran importancia. Sin em­bargo, debido al metabolismo de algunos microorganismos, estos compuestos se pueden acumular en alimentos en concentraciones elevadas, constituyendo un riesgo para la salud de los consumido­res. Para que las aminas biógenas alcancen estas concentraciones elevadas en los (...) alimentos se requiere, como condición indispensa­ble, la presencia de microrganismos productores, por lo que se han desarrollado diferentes métodos para detectar la presencia de los mismos. Entre estos métodos, aquellos basados en técnicas inde­pendientes de cultivo, como la PCR, presentan ventajas como su gran especificidad, el hecho de ser rápidos y de fácil realización, y que en muchos casos ni siquiera es necesario un tratamiento previo de la muestra, lo que facilita su incorporación a las plantas de elabo­ración. En este trabajo se describen algunos de los métodos dispo­nibles en la actualidad para la detección de microorganismos pro­ductores de aminas biógenas, así como sus posibles aplicaciones. (shrink)

The detection of the number of extra–compact dimensions contained in some gravitational models is analyzed resorting to the discontinuity of the specific heat at the critical temperature of a Bose–Einstein condensate. It is shown that the function relating the number of particles and this discontinuity defines a segment of a straight line whose slope depends upon the number of extra–compact dimensions. The experimental feasibility of the proposal is also considered.

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

In the sport context, an essential aspect of an athlete’s development and performance happens during the interaction with the coach while receiving information on the aspects of performance that need to be modified. Grounded in the Self-Determination Theory and particularly on the basic psychological needs theory, a structural equation model was tested with the following sequence: perception of the amount of corrective feedback generated by the coach, perceived legitimacy of corrective feedback, satisfaction of basic psychological needs, and vitality in soccer (...) players. Additionally, simple mediation and serial mediation models were also tested. Participants were 377 Mexican soccer players, who completed the instruments that evaluated the study variables. SEM results reported positive and significant variables’ interrelations in the sequence. The analysis of serial mediation model showed that the perceived legitimacy of feedback and the satisfaction of basic psychological needs fully mediated the relationship between the perception of the amount of corrective feedback generated by the coach and the perception of the subjective vitality of Mexican soccer players. Results suggest that coaches have to ensure that athletes accept the corrective feedback provided and meet their basic psychological needs. Based on SDT tenets, this research highlights the importance for coaches to be aware of the athlete’s perceptions when they are providing corrective feedback and their implications for athlete’s technical development and well-being. It is suggested to incorporate those aspects to training programs for coaches. (shrink)

Rousseau has always had an uncertain relationship with the theory of constituent power. On the one hand, his distrust of political representation and support for popular sovereignty seem consistent with the idea of the people as a legally unlimited constitution-maker. On the other hand, if, from those views about representation and sovereignty, it follows that Rousseau is a proponent of direct democracy, then there seems to be no place in his thought for a theory that presupposes, above all, a separation (...) between those who exercise a delegated authority and those who possess an original constitution-making power. In a legal order in which all laws must be directly made by the people, such a separation is absent: the constituent and the legislative body are one and the same. It is therefore not surprising that Rousseau’s name is largely absent from contemporary literature on constituent power. In this article, however, I will show that once Rousseau’s particular conception of law, as well as his distinction between sovereignty and government, are properly understood, one finds in his work not only the first major formulation of the theory of constituent power, but also a careful exploration of its implications for actual constitutional practice.

Culture has traditionally been considered as a set of knowledge, beliefs, arts, laws, norms, and morals, acquired by a human being as a member of a group. Some anthropologists interpret this as a set of abstract representations, such as information or knowledge, while others interpret it as behavioral control mechanisms. These views assume that the contents of a particular culture must be processed by the minds of individuals, either in a direct way or by resorting to learned mental structures in (...) processes of symbolic socialization. Some critics suggest a problem with these perspectives since they do not provide a convincing explanation of the enculturation process beyond metaphorical images of transfer or internalization of symbolic cultural contents through linguistic transmission. The new embodied theories of cognition, especially enactivism, could give new ideas about what enculturation processes are like, through the concept of participatory sense-making in material culture environments. In this essay, we discuss how an enactive vision of culture could be, and what advantages it would have, as well as the challenges and weaknesses in explaining the culture and its learning processes.

The presence of Neoplatonism in contemporary french phenomenology has a pregnance that crosses its most relevant points. Jean-Luc Marion's work does not escape this. In this work we approach the marionian appropriation of Nicholas of Cusa's thought, in the light of his writing Certitudes négatives, with the intention of understanding the cusanu´s ignorant doctrine as a way of negative certainty.

Participants acting as mock jurors made inferences about whether a person was a suspect in a murder based on an expert's testimony about the presence of objects at the crime scene and the disclosure that the testimony was true or false. Experiment 1 showed that participants made more correct inferences, and made inferences more quickly, when the truth or falsity of the expert's testimony was disclosed immediately after the testimony rather than when the disclosure was delayed. Experiment 2 showed no (...) advantage for prior disclosure over immediate disclosure. Experiment 3 showed that the pattern of inferences when there was no disclosure mirrored the pattern when it was disclosed that the expert's testimony was true rather than false. Participants made more correct inferences from true conjunctions than disjunctions, and from false disjunctions than conjunctions. We discuss the implications for theories of the mental representations and cognitive processes that underlie human reasoning. (shrink)

¿Cuál es el estado de los debates académicos sobre el sexismo en los currículos universitarios de filosofía? La pregunta, así formulada, busca delimitar las principales disputas sobre la incorporación de enfoque de género en los currículos filosóficos en la literatura de la última década. Atendiendo a la revisión sistemática de literatura se realizaron búsquedas en Scopus, Web of Science, Springer, JSTOR, Taylor & Francis y Google Scholar, entre 2012-2022; la estrategia de análisis se centró en los debates recurrentes en el (...) campo. Se analizaron 98 estudios y cinco debates según los cuales las prácticas curriculares excluyentes no permiten la materialización de una educación filosófica inclusiva e intercultural: 1) sesgos implícitos, amenazas por estereotipos y clima hostil, 2) reconocimiento de las mujeres filósofas en el canon y la historia de la filosofía, 3) injusticias epistémicas en la filosofía académica, 4) voces de las mujeres negras en la profesión filosófica y 5) ausencia de las mujeres en la “normalización filosófica” latinoamericana.

Se plantea que los currículos universitarios actuales de filosofía se soportan en estructuras curriculares que conllevarían diversas modalidades de injusticias epistémicas, a saber: el anglo-eurocentrismo, el racismo, el sexismo y el humanismo. Con base en esta premisa, la cual se considera inscrita en la trayectoria histórica de los epistemicidios occidentales, se propone la necesidad de decolonización del currículo universitario de filosofía en las universidades colombianas. Se plantea como un proyecto urgente de acción educativa que, de modo inmediato, contribuiría a contrarrestar (...) las diversas modalidades de injusticias epistémicas y, transitivamente, impulsaría la materialización de lo que aquí se denomina justicia curricular. Esto no solo sería provechoso para mejorar y transformar los currículos de filosofía en el nivel de educación superior y el paulatino enriquecimiento epistemológico de la filosofía, sino que también aportaría a un reconocimiento saludable de la pluridiversidad en la universidad.

Se ofrece una reflexión sobre los avances y las tendencias de discusión en la historia de la tradición filosófica en Colombia y sus presupuestos historiográficos, como un aporte al debate sobre la relevancia de pensar las tradiciones filosóficas nacionales en el siglo XXI. A partir de las categorías valorativas de las diferentes producciones intelectuales se determina si hacen parte o no de la tradición filosófica nacional. El concepto de “normalización filosófica” es analizado como categoría interpretativa de la tradición colombiana y (...) se sugiere su obsolescencia dadas sus implicaciones; con el propósito de superar el reduccionismo, la exclusión y el sesgo al que conlleva esta categoría. Se propone la reivindicación de los intentos de análisis social del siglo XIX y de las producciones filosóficas regionales con el propósito de aportar a una reconstrucción decolonial, amplia y sin sesgos de la historia de la tradición de la filosofía colombiana.

This article analyses the rationality of the principle of proportionality as a justificatory method for solving cases involving conflicts of constitutional principles. It addresses the “problem of comparability”: a set of arguments claiming that proportionalists fail to understand what happens when constitutional principles collide. The problem of comparability suggests that balancing cannot be done if some conflicts of constitutional principles are, in reality, cases of noncomparability, incommensurability, incomparability, or vagueness. In this article, I challenge the views of both proportionalists and (...) their skeptics. Against the skeptics, I argue that proportionality can survive the challenge posed by the problem of comparability. Against the proportionalists, I submit that proportionality cannot be understood as a system of tradeoffs between degrees of satisfaction of principles. If comparison among constitutional principles is to be rational, we need a different approach to normativity—one that allows for the possibility of parity. (shrink)

Los procesos de internacionalización de capitales, así como también el efecto de los medios de comunicación y la producción del conocimiento con sus estrategias racionalizadoras, generan globalmente movimientos sobre los territorios y, muy particularmente, sobre aquellos territorios ricos en biodiversidad; los cuales son presionados para abrirse y negociar productos, patrimonios, experiencias y significados.

PurposeCodes of ethics are important instruments in journalism, as they promote transparency and self-regulation of media, in addition to monitoring the quality of information. The purpose of this paper is to analyse the perceptions that Spanish journalists have of the effectiveness of codes of ethics and to evaluate the different personal and professional variables which condition this vision.Design/methodology/approachThe methodology used in the present study is based on quantitative content analysis using the survey technique. This technique makes it possible to obtain (...) empirical data on various key aspects of the profession that are determining factors in ascertaining Spanish journalists’ views of one of the instruments of accountability that is external to the media: general ethical codes.FindingsThe results show that Spanish journalists are largely confident in the effectiveness of ethical codes in their profession. Likewise, it was seen that variables such as age, professional experience or the media with which they work influence the perceptions that professionals have of such instruments.Originality/valueIf understanding journalism as a profession whose mission is to guarantee the citizens their right to information, then it is essential to be familiar with the tools provided by the profession itself to be accountable to the public regarding this professional mission. Hence the importance of instruments of accountability and the perceptions of the professionals themselves regarding their effectiveness. (shrink)

El conjunto de ensayos que el lector tiene entre sus manos expresa un cuerpo sistemático de ideas provocadoras sobre la tensión entre el constitucionalismo y la democracia. Su autor, el profesor Joel Colón-Ríos, boricua, formado en las dos facultades de derecho canadienses de mayor renombre, e investigador de una de las mejores universidades de Oceanía, las ha fraguado a lo largo de más de un lustro y debatido con gran éxito ante la elite intelectual de Norteamérica. La propuesta central (...) del libro es una original reivindicación de la democracia frente al constitucionalismo. Su institucionalización consiste en un constitucionalismo débil. La piedra angular de este modelo es una constitución inacabada, permanentemente abierta al cambio, que permite y promueve la participación y la deliberación popular continua, en particular, mediante el potencial ejercicio del poder constituyente en cualquier momento. De esta manera, el pueblo tiene la posibilidad de hablar por sí mismo cuando lo juzgue pertinente. Puede cuestionar y reformular los principios básicos de la organización social. No está supeditado a las decisiones adoptadas por los ancestros que expidieron la Constitución, ni por sus representantes que, en el Congreso, ostentan el poder de reformarla. Precio: 49.000 pesos.

The objective of this study is to analyze the relationship between views and social interaction generated by YouTuber videos in Spanish. A quali-quantitative analysis is conducted on a sample of 100 videos, 10 YouTube channels, 997 minutes of video, with 116,934,321 views, 12,297,021 likes/dislikes, and 1,041,191 comments on YT, 306,000 retweets/favorites on TW and 140,852 comments, shares, and reactions on FB. The existence of social media tools on YouTube does not in itself guarantee interaction by users who prefer to watch (...) videos and adopt a passive attitude. In this analysis, we propose a social interaction indicator that takes into account the total number of social media reactions made on social networks and the age of the video. Cultivating realistic conversation and interaction on platforms with audiences numbering in the millions represents a serious challenge for YouTubers. (shrink)

Algunas concepciones tradicionales de cultura suelen considerarla como un depósito de representaciones abstractas (información o conocimiento) mientras que otras la consideran un conjunto de mecanismos simbólicos de control de la conducta. Ambas concepciones suponen que los contenidos de la cultura son procesados o interiorizados por las mentes de los individuos, ya sea de una manera más o menos directa, o recurriendo a las estructuras mentales aprendidas en procesos de socialización simbólica. Las teorías corporizadas de la cognición, en especial el enactivismo, (...) cuestionan estas ideas al no formular claridades sobre cómo se dan estos procesos de enculturación. Se defiende la idea de que la cultura debería ser considerada más allá de sus resultados (conocimientos, creencias, valores, costumbres, leyes, etc.) y comprenderla como un conjunto de prácticas significativas en los que sus procesos de enculturación se dan por el acople dinámico entre los agentes humanos y sus entornos de cultura material, a través de la búsqueda de sentido participativa. Se discute si esta idea de presentar la cultura desde un punto de vista enactivo puede llevar a un reduccionismo biologicista, así como también de qué manera podría relacionarse el enactivismo con enfoques cercanos como la psicología ecológica.

ABSTRACT Despite journalism’s commitment to ethical principles such as accuracy, humanity and diversity, compliance with the gender perspective in content is still minimal in approximately one hundred countries. This inequality reinforces misperceptions, imbalances, and perceived differences between men and women. To address this situation, from 2010 to 2021, eight Spanish media companies appointed a new editorial position responsible for self-regulating gender equality. This qualitative study focused on 10 journalists who currently exercise or have exercised that job, to detect, describe and (...) propose the implementation of this new professional role. This study suggests that gender editing has advanced equality in parity of sourcing and the presence of women in the opinion sections, but implementation of equality in overall content is more difficult. Gender editors’ daily work is hampered by a lack of management support and an absence of independence in editorial decisions. (shrink)

Denying the conclusion of a valid argument is not generally permissible if one suspends on one premise of the argument and believes the other premise. This can happen when one’s only critique of an argument is to undermine one premise. There is incoherence there. Here I examine how this is relevant to the debate on evolutionary debunking of our moral knowledge. I argue that one significant line of response to the debunker is unsuccessful: merely undermining the debunker’s empirical claim. It (...) is not rational to respond this way and believe one has moral knowledge. First I present evidence that prominent critics of the debunking argument merely undermine the debunker’s empirical claim. Then I argue for two premises: merely undermining a premise can only justify a middling amount of doubt towards the premise and we should have no more doubt about the conclusion of a valid argument than we do about the premises. Implications of the argument are explored. (shrink)
