Atoms and molecules are particular kinds of restricted n-body systems, which generally behave as quasi-separable, unlike other n-body systems, e.g., Newtonian ones. The Coulomb repulsion and the Pauli exclusion principle in atoms and molecules are responsible for that separability. Additionally, chemical bonds, especially covalent bonds, enhance the separability of molecules. Independent particle models do not describe atoms and molecules since first-order energy corrections are high. However, these corrections obtained by the first-order perturbation or mean-field strongly converge, implying a one-electron effective (...) potential description. Consequently, stable states of atoms and molecules can be reasonably described by one-electron effective potentials, which strongly differ from other n-body problems. We discuss the peculiarities of the correlation motion of generic systems in the context of the four fundamental forces. In particular, we have shown that the two components (attraction and repulsion) of the electromagnetic force confer a relatively low correlation motion to atoms and molecules. We discuss the physical and chemical nature of atoms and molecules, comparing the degrees of separability between different systems. For example, the separability of Newtonian systems is generally possible in particular classes of restricted systems due to relative mass differences. However, for atoms and molecules, the separability is much broader. (shrink)

Referirse a la multiplicidad es un lugar común cuando se trata de la obra de Alain Badiou, en tanto es una producción de una notoria complejidad y la exploración de sus diversas facetas es adentrarse en un universo de múltiples dimensiones. En este sentido, se propone comparar su producción con un caleidoscopio, un artefacto que revela la multiplicidad como esencia de la unidad y, a su vez, confiere significado a esa diversidad. Esta multiplicidad caleidoscópica no se limita únicamente a la (...) figura del intelectual y sus escritos, sino que se expande hacia otros ámbitos. En efecto, al analizar sus primeras obras y los inicios de su trayectoria intelectual se vuelve evidente la influencia de Sartre, así como sus conexiones posteriores con el estructuralismo francés y, en particular, con la figura de Louis Althusser. Por otra parte, interesa aquí destacar que las producciones de Badiou, lejos de encerrarse en debates del ámbito académico, se entrelazan con tópicos como la cuestión del amor, la cual se conecta de modo directo con el resto de sus reflexiones teóricas y políticas. De este modo, interesa aquí apreciar esta particular intersección que permite una comprensión más profunda de su pensamiento y su preocupación radical por lo social. (shrink)

This article seeks to reconsider some colonial and contemporary readings around a paradigmatic figure: Malintzin. With this objective I will divide our approach into four correlated sections. The first introduces some elements around the construction of the term Malintzin, highlighting those that are related with the Nahua cultural world. The second takes up the colonial chronicles of Bernal Díaz del Castillo and Diego Muñoz Camargo, identifying their specific contents related to her figure. The third delves into some contemporary contributions (...) of a literary, historiographical and philosophical nature. To this purpose I will recover the literary appreciations of Octavio Paz, the historical proposals of Matthew Restall, and the philosophical approach of Bolívar Echeverría. The fourth section functionalizes some final considerations related to Malintzin as useful perspective to problematize the contemporaneity of the conquest of Mexico. Lately, this article seeks to ask and reflect on Malintzin in terms of the construction of an imaginary that posits a multidirectional understanding of her figure. (shrink)

En el siguiente estudio se evalúa un panorama con respecto al comportamiento sociológico en un preámbulo tanto antes durante y después de esta crisis social que se está viviendo debido a la pandemia de hoy en día. Por ello para sustentar dicha investigación se realizó un censo en el cuál, mediante el uso de herramientas estadísticas, se pudo realizar una comparación entre un antes y un durante de la pandemia, lo cual facilitaría intrínsicamente a la predicción de una denominada post (...) pandemia. En este texto se pretende detallar el proceso y forma de la encuesta, al igual que los resultados obtenidos de la misma. Se proveen, además, posibles explicaciones para estos resultados, guiándose por las restricciones de salud nacionales como posibles razones para el cambio de comportamiento actual.

This paper delves into the deconstruction of the notion of responsibility, drawing a correlation with the process of decomposition of the concept of sovereignty as discussed by Derrida in his last research works. We explore Derrida’s consideration of absolute responsibility as no longer passing through the figure of the sovereign. Derrida’s thought takes its distance from the philosophical and hegemonic determination of the notion of responsibility, for the conceptual system of its axiomatic defines responsibility based on the sovereign individual’s freedom (...) and makes responsibility the effect of his power. Yet, this definition condemns ethics to failure, since it does not account for the other supposed in the idea of response. Derrida incorporates absolute singularity, and consequently secrecy, into the structure of responsibility, enabling thought to encounter the absolute other. The text outlines the influence of Nietzsche and Celan in Derrida’s thought and develops an approach that sees in his work the effort to create a poetic revolution in the history of philosophy and knowledge by opening thought to radical alterity.

Due to the COVID-19 Pandemic, several changes have been forcibly made and observed in various fields and areas of society, one of which include the field of education; the foundation of the formation of intellect and knowledge. After two years of studying indoors and private educational institutions holding virtual classes, the time has finally come for students to be re- adjusted once more to the blended mode of learning; a combination of virtual and in-person classes. Thus, this study aimed to (...) investigate the development of students’ study habits and how these habits could potentially affect the students’ academic achievement or performance. The study utilized a descriptivecorrelational design to examine the impact of study habits to the academic performance of 137 senior high school students. The study made use of the Palsane and Sharma’s Study Habits Inventory, or also known as PSSHI, and using this instrument, the study has been able to procure sufficient results that will answer the present study’s problems. Using linear regression analysis, the present study found that there was a significance between the study habits and academic performance of the senior high school students, thus the study’s null hypothesis was eventually rejected.

It is not yet clear which response behavior requires self-regulatory effort in the moral dilemma task. Previous research has proposed that utilitarian responses require cognitive control, but subsequent studies have found inconsistencies with the empirical predictions of that hypothesis. In this paper we treat participants’ sensitivity to utilitarian gradients as a measure of performance. We confronted participants (N = 82) with a set of five dilemmas evoking a gradient of mean utilitarian responses in a 4-point scale and collected data on (...) heart rate variability and on utilitarian responses. We found positive correlations between tonic and phasic HRV and sensitivity to the utilitarian gradient in the high tonic group, but not in the low tonic group. Moreover, the low tonic group misplaced a scenario with a selfish incentive at the high end of the gradient. Results suggest that performance is represented by sensitivity correlated with HRV and accompanied with a reasonable placement of individual scenarios within the gradient. (shrink)

Analizaremos algunos rasgos del proceso de transformación económica y social que tuvo lugar en al-Andalus entre los siglos X y XII, en el marco de la «revolución económica» de la Europa plenomedieval, tomando como caso de estudio la región oriental de la península ibérica. El proceso debió de arrancar con un despegue demográfico y con el aumento de la productividad agrícola, en este caso derivado de los progresos técnicos asociados a la llamada «revolución verde» islámica de los siglos VIII al (...) X. El incremento creciente de los beneficios derivados del campo y el interés por aprovecharlos seguramente impulsó la coacción de las élites urbanas sobre las comunidades campesinas para arrebatarles las tierras más rentables. También pudo ocasionar la colonización de áreas rurales menos favorecidas, que hasta ese momento habían permanecido incultas, por parte de esos grupos acomodados que buscaban expandir los cultivos comerciales, así como por familias de campesinos desposeídos de las mejores tierras. Los cambios en el mundo rural influyeron en el crecimiento de las ciudades debido a la inmigración de la población del campo, presionada y desplazada, que se incorporaba como proletariado urbano ante el incremento en la demanda de manufacturas y bienes de consumo por parte de los terratenientes enriquecidos que habitaban esas ciudades.

En su intervención en el debate alemán de finales del siglo XVIII sobre el significado de la ilustración, Moses Mendelssohn asigna a la ilustración (Auflkärung) y a la cultura (Kultur), componentes teórico y práctico respectivamente de la formación (Bildung) de un pueblo, una función de profilaxis recíproca. El desarrollo de cada una constituye el mejor medio para prevenir la corrupción que produce el mal uso de la otra. Dado que la “manera de destruir” de cada una se contrapone a la (...) de la otra, la felicidad de una nación depende de su avance equilibrado. La intención de este artículo es determinar la posición de Mendelssohn respecto a los límites de la ilustración así como clarificar el vínculo profiláctico entre ilustración y cultura. (shrink)

Coping with assessment tests are known to generate anxiety frequently in the students who face them. In academic circumstances with the continued presence of emotional disturbance, high demand, and stress, emotional and physical fatigue, typical of burnout syndrome, and can be detected. Anxiety and burnout are related to each other and even more closely in high-stakes tests. One of these tests is the examination imposed in Spain for access to the university. The objective of this work is to analyze the (...) presence of anxiety and burnout and the relationship between them in students who face these tests, both during the confinement situation due to the COVID-19 pandemic and during the pandemic after the lockdown. For this purpose, we used a sample of 1,021 students with a mean age of 17.89. Of these, 866 were students who were taking the test, while the rest were university students who had passed it recently. Our results show high levels of anxiety and burnout in students who face the evaluation test during the COVID-19 pandemic, sustained over time and especially in comparison with students who had already taken the exam. The association between higher levels of anxiety and higher levels of burnout in the students who take these exams was also verified. These results link the relationship between these two variables more solidly and suggest the need to include address anxiety to reduce burnout levels in these students. The results are discussed with regard to prior evidence and their applications. (shrink)

El conjunto de tratados de agricultura que se elaboró en al-Andalus ha sido hasta ahora explotado como fuente para aspectos relacionados con la botánica y la historia de las técnicas agrícolas; sin embargo, se ha empleado poco para la obtención de información histórica, aspecto que hemos tratado de enfatizar en este trabajo. Con este objetivo, hemos intentado situar la eclosión de los libros de agricultura en su contexto histórico: el de la revolución económica y demográfica plenomedieval, uno de cuyos aspectos (...) más significativos fue la expansión agrícola impulsada por un estamento de terratenientes, muchos de ellos residentes en las ciudades, que puso en marcha una producción orientada básicamente al mercado. A este grupo social es al que creemos estaban destinados principalmente los libros geopónicos, pues tenía la necesidad y los recursos económicos e intelectuales para aprovecharlos, a diferencia de los pequeños propietarios y las comunidades gentilicias de campesinos que practicaban una agricultura destinada esencialmente al autoabastecimiento. Una vez que reconocemos los libros de agricultura como auténticos manuales de aquellos hacendados, se puede recuperar esa literatura como fuente histórica de primer orden con el fin de conocer el funcionamiento y la organización de ese tipo de propiedad fundiaria en esta fase de la historia de al-Andalus.

Resumen. A la Sociedad Cooperativa, se le distingue por ser una sociedad mercantil con ciertas particularidades a diferencia de los demás tipos de sociedades, tan es así que se rige por su legislación especial. En los últimos años en México, se ha detectado un incremento de sociedades cooperativas dedicadas al suministro de personal, toda vez que el esquema fue considerado por algunos especialistas fiscales como una alternativa para las empresas que buscan disminuir sus cargas impositivas derivadas de las relaciones laborales. (...) Dicho esquema básicamente consiste en transferir a los trabajadores de las empresas a la sociedad cooperativa, los cuales al ser registrados como socios, las remuneraciones que estos perciben son bajo el concepto de previsión social; en lugar de salarios evitando así la retención y pago del Impuesto Sobre la Renta correspondiente. Con motivo de lo anterior, en la presente investigación se analizan y califican los aspectos más relevantes del asunto.Palabras claves. Sociedad cooperativa, evasión fiscal, outsourcing, previsión social.. A cooperative society is distinguished as a corporation with certain features unlike other types of companies, so much so that is governed by a special legislation. In recent years Mexico has seen an increase of cooperative societies dedicated to supply services, since the scheme was considered by some experts as an alternative tax for companies seeking to lower their tax burdens resulting from relations. This scheme basically consists of transferring workers from companies to the cooperative, which when registered as members the remuneration that they perceive are under the concept of social welfare, instead of avoiding wage withholding and payment of VAT Income for. On the occasion of the above, this research analyzes and scored the most relevant aspects of the case. (shrink)

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.

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.

Resumen: La imposibilidad del desarrollo para conciliar normativamente imparcialidad con pluralidad responde a un sesgo de carácter ontológico. Esta ruptura, que constituye la esencia misma de los estudios del desarrollo, supone aceptar que cualquier teoría del desarrollo que se precie se encuentra sustancialmente inacabada. De tal imposibilidad emerge, sin embargo, un perfeccionamiento que transcurre dialécticamente en términos de doble negación hegeliana por el cual las distintas teorías van perfeccionándose a partir de un mayor grado de concienciación normativa. Este perfeccionamiento alcanza (...) analíticamente un estado absoluto de desarrollo definido como libertad. Un concepto que perfecciona el presentado por Amartya Sen, facultado para reconciliar analíticamente el sesgo originario.: The impossibility of development to gather normatively impartiality and plurality makes itself to be ontologically incomplete. Nevertheless, the analytical that emerges in the very essence of development discipline implies to accept that any development theory is and will always be unfulfilled. Nevertheless, and beyond that substantive impossibility, an improvement occurs dialectically in terms of Hegelian double negation by which each theory is overcome by a higher grade of normative awareness by the following one. This improvement reaches analytically an absolute dimension of development as freedom. A concept that goes beyond such introduced by Amartya Sen, which it is well able of including all human determinations that ultimately allow to meet analytically those edges of the gap. (shrink)

In this paper, two different philosophical proposals to introduce and carry out philosophy in school spaces which include the participation of children are compared, these are: Philosophy for Children, mainly developed by Matthew Lipman and Ann Sharp, and Philosophy with Children, which is actually a set of “second generation” proposals –as described by Vansieleghem and Kennedy, based on Reed and Johnson –, among which those created by Walter Kohan and Karin Murris, to mention a few, stand out. The text begins (...) with some similarities between both proposals, before comparing them in each of their dimensions. First, P4C is discussed. Second, PwC. Their ideas about education, school, philosophical education, their concept of childhood, the role given to teachers and their relation with politics are the main focus. Third, PwC’s critique of the P4C programme is studied. Finally, the paper concludes with some ideas on the issue of introducing philosophy to the school space. Particularly, PwC’s proposal is supported, fundamentally because of its coherent acknowledgment of the autonomy of teachers and of the political element in education, since philosophical experience with children is particularly questioning, defying, and, therefore, it has the possibility of bringing about important transformations, both at a personal-individual level, as well as a collective one.

El presente artículo compara las consideraciones de Hegel y Husserl sobre la intersubjetividad en relación a la normatividad.

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

Linguistics of Saying is to be analyzed in the speech act conceived as an act of knowing. The speaking, saying and knowing subject, based on contexts and the principles of congruency and trust in the speech of other speakers, will create meanings and interpret the sense of utterances supplying the deficiencies of language by means of the intellective operations mentally executed in the act of speech. In the intellective operations you can see three steps or processes: first the starting point, (...) intuition or aísthesis; second, the process of abstraction; and third, the inverse: the process of determination or fixing the construct created.

El sistema de Cooperación Internacional al Desarrollo es epistemológica y operativamente ajeno a la complejidad reinante en su mundo de actuación. Su tradición académica ha venido históricamente determinada por dos reacciones antitéticas. Porun lado, restringe la realidad a un principio universalista donde el desarrollo es interpretado apriorísticamente. Por el otro, se somete a un empirismo extremo donde superando el carácter especulativo del anterior, se incapacita para forjar una teoría sobre lo que realmente funciona. En uno y en otro, el fetichismo (...) de la ayuda terminasiendo el precio que recurrentemente se paga ante la incapacidad para reconciliar ambas posiciones.

Linguistics of saying studies language in its birth. Language is the mental activity executed by speaking subjects. Linguistics of saying consists in analyzing speech acts as the result of an act of knowing. Speaking subjects speak because they have something to say. Tthey say because they define themselves before the circumstance they are in. And this is possible because they are able to know. Speaking, then, is speaking, saying and knowing. In this sense there is a progressive determination. Knowing makes (...) possible saying, and saying determines speaking, or, in other words: speaking involves saying and knowing, and saying involves knowing. The problem thus is to determine the meaningful intentional purpose of the individual speaker to say something in every speech act. (shrink)

This paper deals with the question of whether uncertainty regarding model structure, especially in climate modeling, exhibits a kind of “chaos.” Do small changes in model structure, in other words, lead to large variations in ensemble predictions? More specifically, does model error destroy forecast skill faster than the ordinary or “classical” chaos inherent in the real-world attractor? In some cases, the answer to this question seems to be “yes.” But how common is this state of affairs? Are there precise mathematical (...) results that can help us answer this question? And is dependence on model structure “sensitive” in that arbitrarily small errors can destroy forecast skill? We examine some efforts in the literature to answer this last question in the affirmative and find them to be unconvincing. (shrink)

In this essay I revise, based on the notion of the ‘enlightened ruler’ or mingzhu and his critique of the literati of his time, the common belief that Han Fei was an amoralist and an advocate of tyranny. Instead, I will argue that his writings are dedicated to advising those who ought to rule in order to achieve the goal of a peaceful and stable society framed by laws in accordance with the dao.

Argumentation represents a way of reasoning over a knowledge base containing possibly incomplete and/or inconsistent information, to obtain useful conclusions. As a reasoning mechanism, the way an argumentation reasoning engine reaches these conclusions resembles the cognitive process that humans follow to analyze their beliefs; thus, unlike other computationally reasoning systems, argumentation offers an intellectually friendly alternative to other defeasible reasoning systems. LogicProgrammingisacomputationalparadigmthathasproducedcompu- tationallyattractivesystemswithremarkablesuccessinmanyapplications. Merging ideas from both areas, Defeasible Logic Programming offers a computational reasoning system that uses an argumentation engine (...) to obtain answers from a knowledge base represented using a logic programming language extended with defeasible rules. This combination of ideas brings about a computationally effective system together with a human-like reasoning model facilitating its use in applications. (shrink)
