El TDAH constituye un trastorno de gran frecuencia en la niñez. Se caracteriza por patrones persistentes de desatención, hiperactividad-impulsividad. La condición de TDAH se ha asociado con el mecanismo cerebral cognitivo de auto regulación conocido como Funciones Ejecutivas. El presente trabajo de carácter cuantitativo, correlacional y transversal se focalizó en describir y comparar el rendimiento de Funciones Ejecutivas según padres y profesores en una muestra de escolares con y sin diagnóstico de TDAH. La metodología considero la administración de pruebas de (...) diagnóstico de TDAH y de evaluación de FE a través del Inventario Comprensivo de Funciones Ejecutivas. Los resultados indicaron diferencias significativas entre la evaluación de padres y profesores, como también entre las pruebas administradas. Los padres tenderían a evaluar el rendimiento de funciones ejecutivas en términos más flexibles que los docentes. (shrink)

The article aimed to determine the relationship between neuroscience and emotional states in university faculty members from Latin America during the post-pandemic stage of COVID-19. It highlights the importance of understanding emotions from a neuroscientific perspective to develop strategies that enhance emotional management and resilience in the educational context. The descriptive-correlational research included a sample of 318 faculty members from various Latin American countries. The results revealed severe levels of stress (88.4%) and anxiety (92.1%), as well as inadequate (40.9%) or (...) moderate (46.9%) levels of resilience among the faculty members. A strong positive correlation was found between neuroscience and emotional states (rho=0.860), as well as a good positive correlation between neuroscience and resilience (rho=0.739). The study concludes that the knowledge and application of neuroscience principles could contribute to lower levels of stress and anxiety and increase resilience in university faculty members, emphasizing the importance of integrating these disciplines into the understanding and management of emotions in the educational field.

Power in meetings may be enacted in many ways, ranging from democratic and collaborative through to authoritative and didactic, with the exact positioning on this continuum typically under the control of the chair. By contrast with the focus of most previous research on the behaviour of institutionally ratified chairs of intact teams, this paper examines how volunteer chairs of small focus groups in public meetings use the power associated with that role to manage the discussion and to encourage or discourage (...) explicit expression of disagreement. Our analysis identifies ways in which these arbitrarily assigned chairs influence and facilitate the small group discussions through a range of discourse practices. By separating the chair role from its typical co-occurrence with institutional hierarchy we are able to demonstrate the inherent influence and power of the position in the decision making process.

We present a fully relational definition of inertial systems based in the No Arbitrariness Principle, that eliminates the need for absolute inertial frames of reference or distinguished reference systems as the ``fixed stars'' in order to formulate Newtonian mechanics. The historical roots of this approach to mechanics are discussed as well. The work is based in part in the constructivist perspective of space advanced by Piaget. We argue that inertial systems admit approximations and that what is of practical use are (...) precisely such approximations. We finally discuss a slightly larger class of systems that we call ``relatively inertial'' which are the fundamental systems in a relational view of mechanics. (shrink)

La biopolítica ha devenido, sin duda, una de las categorías centrales para la reflexión política contemporánea. Dada su importancia, resulta imperioso avanzar sobre algunas operaciones teóricas que no logran dar cuenta de su especificidad, en tanto que administración de la vida como forma de dominación. Al respecto, y con la intención de rehabilitar la conceptualización de la política, nos interesa demostrar cómo la aparente dicotomía entre zoé y bíos que pretende discutir Agamben no encuentra respaldo en los textos que él (...) mismo utiliza (fundamentalmente, Aristóteles y Foucault), ni tampoco en la cristalización de tales categorías en prácticas sociopolíticas (por ejemplo, la disciplina moderna con sus raíces en el monasterio cristiano). Precisamente, la identificación de la zoé ya como forma de vida es lo que nos permite comprender el interés biopolítico por gestionar la vida biológica. Así, solamente habiendo clarificado estas categorías, podrá rehabilitarse un pensamiento político sobre la política. (shrink)

Resumen: Este artículo analiza cómo se encadenan los planos de lo ontológico y lo óntico en la Teoría Política del Discurso de Ernesto Laclau. Se concluye que, desde el plano ontológico, la hegemonía constituye una forma político-discursiva de articulación y universalización relativa, precaria, contingente y parcial de los particularismos en significantes vacíos que actúan como puntos nodales. Desde el nivel fenoménico-político, Laclau pone en juego estos conceptos para mostrar el desplazamiento y contaminación discursiva entre lo particular y lo universal en (...) la operación hegemónica, que transforma las identidades políticas y construye un orden comunitario y un nuevo sentido común. Desde el nivel ético-político, la conceptualización de la hegemonía se articula a la construcción discursiva de una estrategia socialista y a una democracia radical. Este proyecto político lucha contra los esencialismos y las formas de explotación y opresión social y por un horizonte de liberación que amalgame las luchas de los grupos subordinados y reconozca las diferencias y particularidades como constitutivas y deseables. La teoría formal del populismo presenta algunas inconsistencias óntico-ontológicas en este esquema. Sin embargo, su sobredeterminación simbólica disuelve las disyunciones tajantes entre la lógica y el análisis histórico-político y entre la forma y el contenido. Ello pone de manifiesto el mutuo anudamiento entre lo óntico y lo ontológico y la centralidad de la noción gramsciana de hegemonía para el análisis político y crítico de fenómenos y procesos históricos contemporáneos.: This article analyzes how the ontological and ontic planes are interconnected in Laclau’s political discourse theory. It is concluded that, on the ontological level, hegemony constitutes a political-discursive form of relative, precarious, contingent and partial universalization and articulation of particularities in empty signifiers that act as nodal points. On the phenomenological-political level, Laclau shows the displacement and discursive contamination between the particular and the universal in the hegemonic operation which transforms political identities and builds a communitarian order and a new commonality. On the ethical-political level, the conceptualization of hegemony is articulated as the discursive construction of a socialist strategy and a radical democracy. This political project fights against essentialisms and forms of exploitation and social oppression of subordinate groups, and in favor of a horizon of liberation that recognizes conflicts and differences as constitutive and desirable. The formal theory of populism presents some ontic-ontological inconsistencies in this scheme. However, its symbolic overdetermination dissolves the disjunctions between logic and historical-political analysis and between form and content. This reveals the mutual interconnection between the ontic and the ontological, and the central relevance of the Gramscian notion of hegemony for the political and critical analysis of contemporary historical phenomena and processes.

Aristóteles sostiene que los animales no requieren un monarcon con poderes arbitrarios para gobernarse, como tampoco lo requiere una ciudad bien gobernada. Con ello inaugura una analogía entre la vida animal y la vida política. Examinando algunos textos de él y de filósofos posteriores (Vitoria, Locke, Condillac y Rousseau), se constata que la analogía tiene continuidad y que se complementa con nociones modernas, como la de soberanía e interés. Aplicado por Condillac a los animales, el interés es entendido como una (...) guía que orienta la vida de los animales, y no sólo como un "instinto" conducente a obtener alimentación y reproducción. Asimismo, la capacidad de movimiento de algunos animales requiere algún grado de conciencia de sí, del entorno y de la propia posibilidad de muerte. El conjunto lleva a que es difícil hablar de lo político sin una analogía con la vida animal o viceversa y a que dicha analogía obligaría reconocer derechos a los animales, tal como se constata ya en la jurisprudencia y en algunos textos jurídicos. Aristote maintains that, in order to govern themselves, animals need neither a monarcon with arbitrary powers, nor a well governed city. With this assessment he establishes an analogy between animal life and political life. Following analysis of some of his and later philosophers' (Vitoria, Locke, Condillac, and Rousseau) texts, we can affirm that this analogy has displayed continuity and that it is complemented with some modern concepts, such as those of sovereignty and interest. Applied by Condillac to animals, the concept of interest is understood as a guide that orientates their life, and not only as an "instinct" conducive to obtaining food and enabling reproduction. Likewise, the capacity of movement of some animals requires a certain degree of consciousness of self, of the environment and of the possibility of their own death. The ensemble shows that it is hard to talk about the political without an analogy with the animal life, and vice versa; and that the analogy would support the obligation to recognize rights of animals, as already some courts have decided and as can be found in some legal texts.

David Fabricius, a Reformed pastor in Ostfriesland, was highly regarded by Kepler as an exceptional observer, second only to Tycho Brahe. From 1596 to 1609, Fabricius engaged in extensive correspondence, exchanging numerous letters with Brahe and subsequently with Kepler. These communications also provided values for direct observations on meridian altitudes of planets and stars, as well as elongations between a planet and a star or between two stars. We provide a detailed summary of Fabricius’s observations and compare them with the (...) prediction of twenty-first-century models. The analysis indicates that under specific conditions, his observations exhibit sub-arcminute deviations in relation to those calculated from modern theories. Our findings preliminarily indicate that Fabricius’ astronomical observational abilities were comparable to, an occasionally superior to, those of Brahe himself. We provide machine-readable tables of his observations. (shrink)

Este trabajo estudia la teoría de los diferenciales de Salomon Maimon como respuesta a la cuestión quid juris y a la vez como clave para la fundamentación de la posibilidad de la metafísica como ciencia. Se reconstruye primero la crítica de Maimon al tratamiento kantiano de la pregunta quid juris. Luego, se analiza la respuesta del propio Maimon a esa pregunta, para establecer finalmente cómo tal respuesta abre el camino para la explicación de la posibilidad de la metafísica como ciencia.

This book gathers international and interdisciplinary work on youth studies from the Global South, exploring issues such as continuity and change in youth transitions from education to work; contemporary debates on the impact of mobility, marginalization and violence on young lives; how digital technologies shape youth experiences; and how different institutions, cultures and structures generate a diversity of experiences of what it means to be young. The book is divided into four broad thematic sections: Education, work and social structure; Identity (...) and belonging; Place, mobilities and marginalization; and Power, social conflict and new forms of political participation of youth.

During the second half of the nineteenth century, electronegativity has been one of the most relevant chemical concepts to explain the relationships between chemical substances and their possible reactions. Specifically, EN is a property of the substances that allows them to attract external electrons in bonding situations. The problem arises because EN cannot be measured directly. Indeed, the only way to measure it is through different properties that do can be directly measured, for instance enthalpy, ionization energies or electron affinities. (...) What is particularly troubling about this case in quantum chemistry is that the different models used to describe and quantify EN are incompatible but, in a certain sense, equivalent because the same EN scale results in all of them. By analyzing Linus Pauling’s and Robert Mulliken’s models of EN, it will be argued that, if we remain cling to a traditional representative conception of models, we cannot understand the meaning of the information provided by those models. Indeed, if we do not want to adopt an instrumentalist point of view concerning chemical knowledge, we should reconsider by virtue of what a model represents the system, or, in other words, which the factors that determine the representative power of a model are. I will propose a new perspective that incorporates the role of experimental techniques in the very notion of representation; this perspective allows us to understand how supposedly incompatible models of the same target system can be both simultaneously representative.

Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a "real" existence. In this context, the aim (...) of this paper will be to analyze the ontological status of phonons. For such purposes we will critically analyze the arguments that would account for the presumed nonexistence of phonons. Finally, having already demonstrated that there are not enough reasons to consider phonons as non-existing entities, we will explore some possibilities that allow us to elucidate their ontological status.

Resumen El artículo tiene como objetivo revisar y analizar los pasajes referentes al territorio chileno en los poemas épicos que cantaron la Guerra de Arauco en el siglo XVI. Aun cuando su argumento central consistió en los acontecimientos bélicos, algunos pasajes dieron cabida a la descripción del espacio como un paisaje épico. Así como se demostrará, su representación no solo se configuró atendiendo a las condiciones fisonómicas del territorio, sino también a los recursos literarios propios de la epopeya que caracterizaron (...) al sur de Chile como un escenario desafiante y peligroso, espacio histórico y a la vez literario, representativo de la condición heroica e indomable del Reino de Chile.The aim of this article is to review and to analyze the passages relating to the Chilean territory in the epic poems that reported Arauco's War in the 16th century. Even if their central argument consisted of the warlike events, some passages gave content to the description of the space as an epic landscape. As it will be demonstrated, the representation of the territory not only was formed attending to the physical conditions of the land, but also to the literary resources of the epic that characterized to the south of Chile as a challenging and dangerous scene, historical and simultaneously literary space, representative of the heroic and indomitable condition of the Kingdom of Chile.

RESUMEN Introducción: La dimensión ambiental constituye un proceso esencial en la formación de profesionales, de modo que en el desempeño de su profesión puedan educar hacia el desarrollo sostenible a las futuras generaciones. Objetivo: Representar en un modelo pedagógico la lógica de la dimensión ambiental en la formación laboral investigativa de los profesionales en la universidad. Materiales y métodos: Se utilizaron métodos teóricos, empíricos y matemáticos-estadísticos. Resultados: Elaboración del modelo pedagógico de dimensión ambiental en la formación laboral investigativa de los (...) profesionales en formación. El modelo está estructurado en tres subsistemas: uno teórico, se centra en la integración de saberes pedagógico ambientales a partir de las relaciones que se establecen entre sus componentes, otro metodológico, el cual resume la proyección ambiental de la formación laboral investigativa y un subsistema procedimental, que manifiesta la instrumentación transformadora ambiental que debe ocurrir en los estudiantes. El modelo aporta una cualidad sinérgica que le imprime identidad, totalidad y contribuye a su autodesarrollo. Conclusiones: Con la elaboración del modelo se revelan nuevas interpretaciones que se manifiestan como relaciones teóricas funcionales surgidas entre los componentes de los subsistemas que lo integran y a la vez, entre los subsistemas como macro componentes. La validación del modelo resultó estadísticamente significativa, mediante la instrumentación de una estrategia pedagógica para la dimensión ambiental en la formación laboral investigativa. ABSTRACT Introduction: The environmental component is an essential process in the training of professionals, that enables them to educate future generations towards sustainable development. Objective: To represent in a pedagogical model the logic of the environmental dimension in the research training of professionals. Materials and methods: Theoretical, empirical and mathematical-statistical methods were used. Findings: The development of the pedagogical model of environmental dimension in research and labor training of professionals. The model is structured in three subsystems: the first focuses on the integration of environmental pedagogical knowledge from the relationships established between its components; the second is of a methodological character and summarizes the environmental projection of research training; whereas the third one is procedural, expressing the environmental transformative instrumentation that must occur in students. The model provides a synergistic quality that consolidates identity, totality and contributes to its self-development. Conclusions: With the elaboration of the model new interpretations are revealed that are manifested as functional theoretical relations arising between the components of the subsystems that integrate it and at the same time, between the subsystems as macro components. The evaluation of the model was statistically significant, through the instrumentation of a pedagogical strategy for the environmental dimension in the research and labor training. (shrink)

Resumen En las últimas décadas las economías nacionales han experimentado un proceso de cambio estructural que ha desafiado la concepción de la competitividad que sostiene la economía ortodoxa. En particular, es necesario un enfoque que tome en cuenta la importancia de los procesos de aprendizaje involucrados en el logro de niveles de competitividad de las empresas y que coloque el acento en los procesos de cambio y de innovación, adoptando una visión dinámica. Teniendo en cuenta ello, en el presente artículo (...) se presenta una visión teórica alternativa de la construcción de ventajas competitivas y de la competitividad de las naciones, a través de la moderna economía evolucionista e institucionalista. Así, se presentan los principales rasgos de la teoría evolucionista de la empresa y el enfoque de Sistema Nacional de Innovación, que posibilita un abordaje sistémico del fenómeno de la competitividad y el desempeño económico de las naciones.

El artículo se propone reconstruir y analizar los aportes del marxista italiano Antonio Gramsci a nivel educativo, dando cuenta de algunas de sus principales conceptos formulados centralmente en los llamados Cuadernos de la Cárcel. Se parte de asumir la centralidad que tiene para él la disputa pedagógica y cultural en el marco de lo que define como hegemonía, concebida como campo de fuerzas asimétrico, dinámica e inestable que,si bien involucra a las instituciones educativas, las excede con creces, condicionando y estructurando (...) al conjunto de la sociedad y al propio Estado, el cual es definido en términos integrales y más allá de su faceta represiva. Ello supone ponderar al sentido común como un territorio privilegiado de disputa hegemónica y a la intelectualidad orgánica como de enorme importancia en esta lucha pedagógico-cultural. (shrink)

El principio de correspondencia y el punto de vista de la complementariedad constituyen los sucesivos ejes alrededor de los cuales gira la interpretación de Bohr de la teoría cuántica. En este trabajo sostenemos que el concepto kantiano de analogía resulta un hilo conductor que permite comprender satisfactoriamente tal desarrollo histórico del pensamiento de Bohr. Mostraremos que el principio de correspondencia guía la búsqueda de analogías en la experiencia, mientras que desde el punto de vista de la complementariedad Bohr establece analogías (...) simbólicas. The principle of correspondence and, later, the viewpoint of complementarity are the axes around which Bohr´s interpretation of quantum theory rotates. In this paper we claim that the Kantian notion of analogy enables a satisfactory understanding of such historical development of Bohr's thought. We shall show that the principle of correspondence guides the search for analogies in experience, while from the viewpoint of complementarity Bohr establishes symbolic analogies. (shrink)

This paper compares Cohen’s Logic of Pure Knowledge and Cassirer’s Substance and Function in order to evaluate how in these works Cohen and Cassirer go beyond the limits established by Kantian philosophy. In his Logic, Cohen seeks to ground in pure thought all the elements which Kant distinguishes in empirical intuition: its matter (sensation) as well as its form (time and space). In this way, Cohen tries to provide an account of knowledge without appealing to any receptivity. In accordance with (...) Cohen’s project of reformulating the Kantian theory of sensibility, Cassirer undertakes in Substance and Function the task of developing an alternative doctrine of pure and empirical manifolds. But whereas Cohen analyzes the laws of pure thought, Cassirer aims to highlight the functional character of concepts in the development of modern mathematics and physics. I will discuss these two different approaches to the problems raised by Kantian philosophy and I will argue that Cassirer went further than Cohen in the project of critical idealism. (shrink)

While mechanics was developed under the idea of reciprocal action (interactions), electromagnetism, as we know it today, takes a form more akin to unilateral action. Interactions call for spatial relations, unilateral action calls for space, just one reference centre. In contrast, interactions are matters of relations that require at least two centres. The development of the relational electromagnetism encouraged by Gauss appears to stop around 1870 for reasons that are not completely clear but are certainly not solely scientific. By the (...) same time, Maxwell recognised the equivalence in formulae of his electromagnetism and the one advocated by Gauss and called for an explanation of why such theories so differently conceived have such a large part in common. In this work we reconstruct and update the relational electromagnetism up to the contributions of Lorentz guided by the non-arbitrariness principle (NAP) that requests arbitrary choices to be accompanied by groups of symmetries. We show that a-priori there must be two more symmetries in electromagnetism, one related to the breaking (in the description) of the relation source/detector and one relating all the perceptions of the same source by detectors moving with different (constant) relative velocities. We show that the idea of electromagnetic waves put forward in concept by Lorenz (1861-1863) before Maxwell (1865) and in formulae (1867) just after Maxwell, together with the ``least action principle'' proposed by Lorentz are enough to derive Maxwell's equations, the continuity equation and the Lorentz' force, and that there is a dual formulation in terms of fields of the receiver (as opposed to fields of the source). While Galilean transformations are associated with removing the arbitrariness implied in the election of a reference space, they will not explicitly appear in a formulation based upon a relational space although we occasionally mention their usefulness. In contrast, Lorentz' transformations will emerge in this formulation involving the relations between the perceived fields of different receivers. Moreover, the role of the full Poincaré-Lorentz group as a group of transformations of the perceived actions is elucidated. In summary, we answer Maxwell's philosophical question showing how the same theory in formulae can be abduced using different inferred entities. Each form of abduction implies as well an interpretation and a facilitation of the theoretical construction. This work relies heavily on logical concepts as abduction put forward by C. Peirce, needed for the construction of theories. (shrink)

Our purpose is to describe the application of legitimate defense in so-called non-confrontational situations. To do this, we will conceptualize gender violence as that which against women, due to their condition as such, and we will describe the absence by the courts in the identification of this problem. Second, we will analyze the reception of Argentine and international legislation on the treatment of gender violence and the recommendations and criteria to take into account when interpreting and applying criminal law. Finally, (...) we will present the treatment of legitimate defense in contexts of gender violence, analyzing each of its elements. Our conclusions will focus on the need to address situations of gender violence based on international regulations for the application of legitimate defense in non-confrontational situations.

The prospective formalization of the Anthropocene as a chronostratigraphic unit by the International Commission on Stratigraphy has been intensely debated. This paper explores and assesses the stakes of this process from a philosophical perspective. I distinguish two senses of formalization—the descriptive and the evaluative—and argue that: 1) there are descriptive and evaluative formalizations of the Anthropocene beyond the confines of the ICS; 2) incoherencies between Anthropocene proposals and the ICS’s current tenets are not a decisive reason for deferring descriptive formalization; (...) and 3) the prospective evaluative formalization of the Anthropocene by the ICS would be impactful.

The aim of this paper is to analyze Dimitry Gawronsky’s doctrine of actual infinitesimals. I examine the peculiar connection that his critical idealism establishes between transcendental philosophy and mathematics. In particular, I reconstruct the relationship between Gawronsky’s differentials, Cantor’s transfinite numbers, Veronese’s trans-Archimedean numbers and Robinson’s hyperreal numbers. I argue that by means of his doctrine of actual infinitesimals, Gawronsky aims to provide an interpretation of calculus that eliminates any alleged given element in knowledge.

Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a “real” existence. In this context, the aim (...) of this paper will be to analyze the ontological status of phonons. For such purposes we will critically analyze the arguments that would account for the presumed nonexistence of phonons. Finally, having already demonstrated that there are not enough reasons to consider phonons as non-existing entities, we will explore some possibilities that allow us to elucidate their ontological status.
