La pandemia por Covid-19 ha supuesto un cambio notable en el sistema educativo. Las adaptaciones en la forma de enseñar han llevado a que primen unas metodologías sobre otras. El AC requiere relaciones interpersonales y por tanto es esperable que se haya visto afectado por la pandemia. En este artículo se analizan 177 aulas de secundaria y se observa que el AC no está suficientemente asentado pero que su uso es sensible a la asignatura, la edad del profesor y el (...) tipo de aula.

As a continuation of the work of the third author in [5], we make further observations on the features of Galois cohomology in the general model theoretic context. We make explicit the connection between forms of definable groups and first cohomology sets with coefficients in a suitable automorphism group. We then use a method of twisting cohomology (inspired by Serre’s algebraic twisting) to describe arbitrary fibres in cohomology sequences—yielding a useful “finiteness” result on cohomology sets. Applied to the special case (...) of differential fields and Kolchin’s constrained cohomology, we complete results from [3] by proving that the first constrained cohomology set of a differential algebraic group over a bounded, differentially large, field is countable.

Las acciones que articulan simbióticamente élites empresariales y políticas, mafias, grupos militares legales e ilegales, se posibilitan bajo la búsqueda de dos fines: uno, reordenar el territorio de manera violenta hiper-acumulando tierras, con el fin de salvaguardar sus intereses económicos e inversiones; dos, hiper-acumular poder político con el fin de sostener sus privilegios, usando dicho poder para la reconfiguración del diseño institucional y la planeación de los territorios imponiendo sus condiciones. Este fenómeno que marca la historia de Colombia es lo (...) que ampliamente podríamos comprender como Criminalidad Corporativa Instaurada.

The aim of this study is to try to make use of real numbers for representing an infinite analysis of individual notions in an infinity of possible worlds.As an introduction to the subject, the author shows, firstly, the possibility of representing Boole's lattice of universal notions by an associate Boole's lattice of rational numbers.But, in opposition to the universal notions, definable by a finite number of predicates, an individual notion, cannot admits this sort of definition, because each state of an (...) individual subject is characterized by the values taken by an infinite number of predicates, each of whom may appear or disappear in the next state.The notion of “degree of identification of an individual notion” is then introduced and arithmetized by a rational number.As an individual notion can be defined by a convergent succession of degrees of identification, the real characteristic number of such an individual notion can be defined by the corresponding convergent succession of rational numbers, satisfying Cauchy's conditions for the convergence of successions.

Food advertising targeted at children is associated with the development of unhealthy eating habits and childhood obesity. In Spain, where one in every three children suffers from overweight, a voluntary regulation mechanism has been adopted to control such advertising, despite evidence of its ineffectiveness. This study's stated objective was to evaluate the grounds for implementing a policy that would ban the advertising of energy-dense, nutrient-poor food and beverages targeted at children in Spain, incorporating an ethical perspective in the analysis. Using (...) a bibliographic search of various databases, we reviewed the evidence for answering the seven questions posed by Walton et al.'s ethical evaluation framework, drawn up on the basis of the Nuffield Council on Bioethics Stewardship model. The results show that the proposed intervention is cost-effective, minimally intrusive, promotes healthy environments, acts on a vulnerable population, helps children lead healthy lifestyles, reduces social health inequalities, increases parents' individual freedom of choice and enjoys the support of scientists, health professionals and consumers alike. Accordingly, we feel that the time has come for food advertising directed to children in Spain to be statutorily regulated, by banning the promotion of EDNP products. (shrink)

En este ensayo sucinto y cargado de significado se reflexiona sobre un Mundo, no disuelto en el nihilismo cáncer de Occidente sino dispensador de espacios y tiempos a través del hombre. El Mundo como Vacío, donde se construyen precarios lugares habitables, ajustando tradiciones a necesidades, e integrando procesos inventivos en un esquema global de asignación de puestos.

Cet article soulève la difficulté majeure que rencontrent certaines institutions spécialisées dans le traitement de l’obésité pédiatrique pour travailler avec les familles. Ces familles sont au cœur de la problématique de ces jeunes : la séparation de l’enfant d’avec ses proches est la base thérapeutique, mais la dépendance est forte et la séparation d’avec les parents, la mère en particulier, difficile. Dans une perspective psychodynamique, les auteurs, chercheurs en psychologie, partent du postulat que l’obésité d’un individu serait révélatrice de conflits (...) intrapsychiques, intersubjectifs, mais aussi d’un symptôme familial transgénérationnel impactant la contenance du groupe. L’institution pourrait alors assurer une fonction substitutive de contenance auprès de ces familles en fragilité d’enveloppes psychiques. À partir d’un exemple clinique institutionnel, l’article montre l’impact dynamique de divers dispositifs thérapeutiques sur l’évolution de l’accompagnement des familles en souffrance de séparation.

ABSTRACT This study analyses the impact of Oswald Spengler’s work in Spain during the interwar period. It proceeds with three steps as follows: The first part investigates the reception of Spengler’s historic morphology of cultures in the so-called circle of the Revista de Occidente. The second part delves into the early echo of Spengler’s work among the Spanish left up to the Second Spanish Republic. The third part focuses on the impact of Spengler’s historic morphology among conservative traditionalists and members (...) of the radical right prior to the Spanish Civil War. This analysis point towards broad, transideological debate on Spengler in Spain that the Spanish right then usurped and radicalised during the 1930s. (shrink)

This article will contrast two portrayals of Protagoras: one in the "Theaetetus," where Socrates discusses Protagorean theory and even comes to his defense by imitating the deceased sophist; and another in the "Protagoras," where Socrates recounts his encounter with the sophist. I suggest that Plato wants listeners and readers of the dialogues to hear the dissonance between the two portraits and to wonder why Socrates so distorts Protagoras in the "Theaetetus." Protagoras in the "Protagoras" behaves and speaks in ways that (...) are incompatible with the Protagorean position presented in the "Theaetetus.". (shrink)

We consider the concept of poverty from the asset-accumulation approach and propose an integrated framework, building upon existing theories, to describe how the interconnected factors of trust (or lack thereof) and social distance can reinforce poverty traps. Social distance is influenced by choice, while trust is the symptom that defines the strength of social ties on a group. We look at how an absence of trust influences how households make decisions about the use and accumulation of assets in ways that (...) could perpetuate poverty. Weak trust also affects how groups interact with each other in a society, creating “trust clusters” within homogeneous groups and antagonism across groups, which in turn affects aspirations and leads to an erosion of the basis of a social contract. For more effective and sustainable poverty reduction, we need to understand these linkages and address them systematically. (shrink)

Sara Ahmed piensa las emociones, los objetos, los espacios y las orientaciones hacia el mundo a partir de sus efectos. Las emociones son realidades públicas que nos pegan y nos separan de los otros, adquiriendo su significación política en el contacto social. La idea de la pegajosidad y el contacto presupone una subjetividad indisociable de su relación con la alteridad. Para explicar esta relación entre el yo y el mundo, Ahmed hace uso de la fenomenología. Una fenomenología queer consistirá en (...) sacar a la luz el fondo de historias, normas y signos que los espacios normativos y los objetos familiares ocultan al presentarse como atemporales y naturales. En este trabajo propongo que la filosofía de Ahmed permite leer las orientaciones, la subjetividad y las emociones en su dimensión narrativa. El protagonismo que adquieren las historias en la teoría queer de Ahmed es útil para pensar el vínculo entre literatura y política a partir de la recepción y la circulación de las obras. Las narrativas feministas contribuyen a generar extrañamiento respecto del mundo normativo, a dislocar el orden familiar. Estos dislocamientos abren grietas desde las que imaginar, a través de la literatura, maneras no normativas de desear y percibir el mundo. (shrink)

The kantian concept of friendship has been recently but yet scarcely studied. However, it has its place as the conclusion of the doctrine of virtue, which gives it some prominence. This article argues that the kantian approach to friendship, as it emerges from the analysis of the texts of the Metaphysics of Morals and the Lectures on Ethics, involves elements that connect with our contemporary sensibility and, far from being a marginal concept in his ethical philosophy, represents one of its (...) crucial moments.

The thesis that I intend to address in this article can be summarized with the idea that positive bonds1 engender not only dependence, but also freedom and autonomy. Accordingly, it is worth asking what positive human bonds are based on. Or, to phrase the question another way, how can dependence and autonomy be blended when we talk about relationships in terms of bonds, that is, relationships with a special quality of union?

In this paper, drawing on evidence internal to the Platonic dialogues (supplemented with some ancient testimonia), I answer the question, “How did Plato teach in the Academy?” My reconstruction of Plato’s pedagogy in the Academy is that there was a single person who read the dialogue aloud like a rhapsode (this is in contrast to the dramatic theatrical hypothesis, in which several speakers function as actors in the performance of a dialogue). After the rhapsodic reading, students were allowed to ask (...) that portions of the text to be re-read, to ask a question about the text, and were encouraged to enter into a broader conversation about the topic and themes brought out by the text. This later pedagogical method of interrogating and investigating a dialogue is of more importance than the mere reading of a dialogue. I contend that Plato’s experiences teaching were woven into some of the dialogues, and that Plato’s pedagogy reflects some of the ways that he taught in the Academy. I propose that excellent points made by students may have been written into revised forms of the dialogue. And not only good points, but also mistakes in reasoning may have been added into the dialogues. I suggest that the way certain dialogues are organized with “guest lecturers” and “tag-team” philosophical debates reflect Plato’s pedagogy in the Academy. Plato’s broadmindedness, his openness to various and opposing viewpoints, is also evident from both outside and inside of the dialogue. Lastly, drawing on the idea of Socratic mimēsis, I give a plausible curriculum for how Plato may have used the dialogues to teach them: he had his students “play” with them. Plato may have asked his students to enter into the roles of the characters in the dialogues to better understand them and the type of person they represent. Plato may have also asked students to take over from the position of the character in the dialogue and to suggest a better, truer account of things than what the characters said or did. (shrink)

In the "Republic," Plato has Socrates attack poetry’s use of mimēsis, often translated as ‘imitation’ or ‘representation.’ Various scholars (e.g. Blondell 2002; Frank 2018; Halliwell 2009; K. Morgan 2004) have noticed the tension between Socrates’ theory critical of mimēsis and Plato’s literary practice of speaking through various characters in his dialogues. However, none of these scholars have addressed that it is not only Plato the writer who uses mimēsis but also his own character, Socrates. At crucial moments in several dialogues, (...) Socrates takes on a role and speaks as someone else. I call these moments “Socratic mimēsis.” While previous commentators have noticed some of these moments, they have either overstated their rarity or they have not studied them collectively. My dissertation is the first in-depth investigation of this phenomenon in the dialogues. Socrates’ dramatic imitation of others is way of teaching in a voice separate from his own, and it is also a way for Plato to speak to, and to educate, different kinds of audiences. Although “Socratic mimēsis” occurs throughout the Platonic corpus, I focus on three passages from three different dialogues, which are paradigm instances: [1] in the "Crito" Socrates plays the part of ‘the Laws’ (50a-54c); [2] in the "Theaetetus" he acts the part of ‘Protagoras’ (166a-168c); and [3] in the "Menexenus" he recites a funeral speech learned from ‘Aspasia’ (236d-249c). Instead of one-sidedly reading the dialogues as either only literary works of art or as only a series of philosophical arguments, this study gleans philosophic insights from the literary and dramatic details of the dialogues. In chapter one I argue that in the "Crito" Socrates tries to convince Crito of a universal and absolute ethics based on never committing injustice, but Crito is not able to understand. In order to make Crito more just—but not yet at the level of Socratic ethics—Socrates creates ‘the Laws’ to persuade Crito to expand his personal notion of justice. Socrates instills a political obedience in place of Crito’s existing lawlessness as a second-best recourse. Plato expects the astute listener or reader to see the contrast between Socrates’ earlier ethical principles, said in his own voice, with what he says in the voice of ‘the Laws.’ In chapter two I argue that in the part of the "Theaetetus" where Socrates defends Protagoras (often called ‘the Defense’), Socrates, by imitating ‘Protagoras,’ is actually criticizing Protagorean relativism. The Protagorean theory cannot account for mimēsis and Socrates’ mimetic act performatively contradicts the identity of appearance and reality, which the theory presupposes. Finally, in chapter three I argue that in the Menexenus the funeral oration that Socrates recounts for Menexenus that he heard from ‘Aspasia’ is actually a disguised criticism of political rhetoric and of Athenian imperialism. Although the speech is never interrogated within the dialogue, Plato provokes the listener or reader outside the dialogue to question its message and to see how it conflicts with many of Socrates’ positions in other dialogues. Beyond reconsidering the long-standing and persistent view that Plato was against poetry and mimetic performance, I re-examine the role that performance and role-playing can have in philosophy and pedagogy more generally. Actors, by taking on other personas, and audience members, in observing actors and their actions, are both involved in acts of imagination that can expand their horizon of thinking and feeling.

Proof-theoretic methods are developed for subsystems of Johansson’s logic obtained by extending the positive fragment of intuitionistic logic with weak negations. These methods are exploited to establish properties of the logical systems. In particular, cut-free complete sequent calculi are introduced and used to provide a proof of the fact that the systems satisfy the Craig interpolation property. Alternative versions of the calculi are later obtained by means of an appropriate loop-checking history mechanism. Termination of the new calculi is proved, and (...) used to conclude that the considered logical systems are PSPACE-complete. (shrink)

La ciudadanía y lo político. Ciudadanía y crisis de la democracia liberal en un mundo en transformación es un texto provocador, que desafía directamente a las esferas de poder económico, político y social en el marco de la corrupción. Deja al descubierto las entrañas cancerígenas de una política enferma de poder, donde priman los intereses particulares o políticos sobre los intereses del pueblo. El libro es una lanza que atraviesa las profundidades que erosionan nuestra sociedad, realizando así un análisis riguroso (...) desde distintas aristas, que tienen un elemento común: la corrupción política. A lo largo de las páginas se ofrece un enorme panorama sobre el papel de la ciudadanía dentro de la sociedad, que reclama a gritos una revolución desalienante frente a la cleptoestructura. Es así como, el papel de la ciudadanía es el centro de la reflexión analítica que nos presenta Joan Lara Amat y León. (shrink)

We introduce frame-equivalence games tailored for reasoning about the size, modal depth, number of occurrences of symbols and number of different propositional variables of modal formulae defining a given frame property. Using these games, we prove lower bounds on the above measures for a number of well-known modal axioms; what is more, for some of the axioms, we show that they are optimal among the formulae defining the respective class of frames.

En este artículo se analiza un conjunto de obras sobre ríos y represas que pertenece a la serie titulada Represa /Represión (2012-) de la artista colombiana Carolina Caycedo. La pregunta de la que se ocupa esta investigación es ¿cómo las estrategias estéticas de estas obras identifican los problemas socio-ecológicos generados por las represas y contribuyen a articular imaginarios políticos de sostenibilidad? El argumento principal es que las obras de Caycedo sobre el río Yuma o Magdalena contribuyen con la construcción de (...) una memoria histórica ambiental, a partir de saberes populares, campesinos y cosmovisiones indígenas. Con este fin, este texto caracteriza el problema de las represas a partir de los conceptos de ‘extractivismo’, de Macarena Gómez-Barris, y ‘desterritorialización’, de Rob Nixon, para luego realizar un recorrido por las obras de la artista, de cuyo análisis se va construyendo una caracterización de la memoria histórica ambiental de un segmento del río Yuma. El marco conceptual del trabajo incluye las nociones de ‘seres-tierra’, de Marisol de la Cadena y ‘territorio’, de Arturo Escobar, así como ‘memoria de los ríos’, de Kristina Lyons. La metodología se basa en el análisis conceptual y técnico de las piezas de Caycedo en el marco interdisciplinar de las humanidades ambientales. El análisis concluye que las obras de Caycedo generan espacios de memoria histórica ambiental desde perspectivas trasnacionales y, en estos espacios de encuentro que constituyen las obras, se relacionan y rearticulan los extremos de falsos antagonismos como naturaleza/cultura, humano/no humano y ciencia/arte.

At the end of the first hypothesis, Parmenides gets Aristotle to agree that being [οὐσίας] must be in time; that is, that being must partake in at least one of the temporal modes: either to have been in the past, to be in the present, or it will be in the future (140e-142a). If this is true, then “the one does not partake in being” (141e7-8), meaning temporal being—to which Aristotle agrees, saying “Apparently not” (141e9). Parmenides then gets Aristotle to (...) agree that “Therefore, ‘the one’ in no way is” (141e9-10). This, however, contradicts the very first premise that begins Parmenides’ entire gymnastic exercise, “if one is” (137c4). The problem with the previous conclusion—that to be is to be in time—is that in professing his assent to it, Aristotle, in fact, gainsays it. He performatively contradicts the very thing he wants to assert. Aristotle answers Parmenides question, “Therefore could something partake of being in any way other than in one of those ways?” (141e7-8) with a two-word answer in Greek: “οὐκ ἔστιν [It’s not possible].” We can, therefore, ask of the very claim Aristotle is making—that it is impossible for something to be and not be in time—when in time does it hold true? At what time is it “not possible [οὐκ ἔστιν]” for something to not partake of temporal being? Is it not possible only in the present moment, in the past, or in the future? If Aristotle’s assertion is to have any force it must hold always. It has the same tenselessness as mathematical propositions, like ‘1+1=2.’ Forms, like mathematical entities, must necessarily have atemporal existence. Accordingly, in atemporally maintaining that anything that is must be in time, Aristotle undermines his own assertion. He performatively contradicts the very thing that he wants to affirm. (shrink)

The present paper tries to answer the question Is religious education compatible with the purposes of liberal education? This work argues that it is possible, and desirable, that democratic states built on liberal ideals include religious education in all schools since increasing the number of options among which the future citizen may choose the conception of the good with which he or she wishes to live is a condition for autonomy as one of its educational purposes. However, the proposal is (...) not based on religious confessional education, which by itself does not satisfy the liberal educational goals, but is redefined from the common principles compatible both religious confessions and non-religious views of morality and citizenship.

b>—Several paradigms (e.g. change blindness, inattentional blindness, transsaccadic integra- tion) indicate that observers are often very poor at reporting changes to their visual environment. Such evidence has been used to suggest that the spatio-temporal coherence needed to represent change can only occur in the presence of focused attention. However, those studies almost always rely on explicit reports. It remains a possibility that the visual system can implicitly detect change, but that in the absence of focused attention, the change does not (...) reach awareness and consequently is not reported. To test this possibility, we used a simple change detection paradigm coupled with a speeded orien- tation discrimination task. Even when observers reported being unaware of a change in an item’s orientation, its nal orientation effectively biased their response in the orientation discrimination task. Both in aware and unaware trials, errors were most frequent when the changed item and the probe had incongruent orientations. These results demonstrate that the _nature _of the change can be represented in the absence of awareness. (shrink)
