This work is descriptive observational, with transversal design, was to analyze the time of motor commitment in Physical Education classes in three subsystems of Venezuelan education. The analysis unit consisted of a discretionary sample of 6 Physical Education classes between initial education, basic education and secondary education, at the rate of 2 classes for each subsystem. The number of students participating was 192. For the observation and registration, was used, the temporal variables were recorded, and in the second instance, the (...) classes were recorded considering variables associated with: organization of groups, activities, disposition of materials, use and distribution of physical space. The results confirm the little use of the Physical Education class to favor the motor development; none of the observed classes managed to accumulate 50% of the time of motor commitment, thus confirming the trend of other investigations.

Conceptual engineering is commonly characterized as the method for assessing and improving our representational devices. Little has been said, however, on how best to construe these representational devices—in other words, on what conceptual engineering should be all about. This paper tackles this problem with a basic strategy: First, by presenting a taxonomy of the different possible subject matters for conceptual engineering; then, by comparatively assessing them and selecting the most conducive one with a view to making conceptual engineering an actionable (...) method, that is, a method that can be applied effectively and consistently to specific case studies. The outcome is that conceptual engineering should be all about concepts on pain of pragmatic inconsistencies otherwise. (shrink)

La denominada 'estrategia del explanandum dual' ha sido utilizada en el pasado para enfrentar problemas de distinta clase, entre los que se cuentan el debate 'explicación vs. comprensión' y el problema de cómo las razones pueden explicar la conducta. Esta estrategia puede ser descripta someramente como un intento de resolver la rivalidad explicativa entre dos explicaciones por medio de la división del explanandum. En este artículo se analiza el uso que Ausonio Marras ha hecho de ella. Este autor ha sostenido (...) que su utilización permite enfrentar el problema de la ineficacia causal de las propiedades mentales, problema que ha representado una seria amenaza en las últimas dos décadas para el programa del materialismo no reduccionista. Se intentará mostrar que la estrategia sugerida no puede ser exitosa frente a este problema a menos que pueda proveerse de una explicación exitosa de cómo las propiedades mentales pueden mantener su eficacia causal completa, y que la respuesta que se ofrece no satisface esta exigencia. The dual explanandum strategy' has been used in the past to contend some quite different problems, including the 'explanation vs. understanding' debate and the problem of how reasons can explain behavior. This strategy can be roughly described as an intent to solve the explanatory rivalry between two explanations by means of the division of the explanandum. In this paper I want to analyze the use of this strategy by Ausonio Marras, who has claimed that it allows us to face the problem of causal inefficacy of mental properties. This problem has arisen in the last two decades in the context of non reductive materialism and has become a serious menace to this program. I try to show that this strategy can not work out this problem unless it can be provided with a successful account of the way that mental properties can keep their complete causal efficacy, and the answer he offers does not satisfy this demand.

El autor procura presentar el pensamiento histórico del Inca Garcilaso, presedido por una nítida visión filosófica de índole platónico-agustiniana. Demuestra que fue el primer filósofo mestizo de América.

La disforia de género pediátrica es una patología psiquiátrica cuya incidencia ha crecido significativamente. Se han propuesto diversas terapias, pero aún no hay consenso sobre la conducta a seguir en estos casos. Uno de los tratamientos sugeridos es la supresión de la pubertad, cuyo objetivo es el de disminuir la angustia del niño que padece esta patología. Sin embargo, este tratamiento ha generado diversos dilemas éticos que todavía no han sido despejados. Por este motivo, basándonos en la evidencia actual, no (...) parece prudente su indicación existiendo otras alternativas terapéuticas que no despiertan controversias. (shrink)

In this paper I argue that the way in which we revise and change our beliefs is different from that in which we revise and change our judgments of value; this is due to the fact that judgments of value, unlike beliefs, have no truth-values. Changes of judgments of value do not answer in the same way to the restrictions that apply to changes of beliefs and that are determined by the norms that govern beliefs. I argue that, first when (...) we revise and change our beliefs, we should be in a position to suspend judgments, and when trying to remove doubts, we should try to avoid falsehood and, second when changing beliefs, we should be in a position to assign probabilities to those conjectures we are in suspense about. These two conditions apply to the case of changes of attitudes with truth-values, such as beliefs; I argue that these two characteristics do not apply to cases of changes of judgments of value.Neste artigo eu argumento que o modo pelo qual nós revisamos e mudamos nossas crenças é diferente daquele pelo qual revisamos e mudamos nossos juízos de valor; isto se dá porque juízos de valor, ao contrário de crenças, não possuem nenhum valor de verdade. Mudanças de juízos de valor não estão sujeitas às mesmas restrições que se aplicam às mudanças de crenças e que são determinadas pelas normas que governam estas. Eu argumento que, primeiro, quando revisamos e mudamos nossas crenças, nós deveríamos ser capazes de suspender juízos e, ao tentarmos suprimir dúvidas, deveríamos tentar evitar a falsidade e, segundo, ao mudarmos as crenças, nós deveríamos ser capazes de atribuir probabilidades àquelas conjecturas sobre as quais nós estamos em dúvida. Estas duas condições se aplicam aos casos de mudanças de atitudes com valores de verdade, tais como crenças; eu argumento que estas duas características não se aplicam aos casos de mudanças de juízos de valor.

v. 1 Na antiguidade e na Idade Média.--v. 2. A civilização do homem-exterior.

El objetivo de este ensayo es abrir un conjunto de preguntas en torno a la materialidad del pensamiento, sin que ello signifique, a fin de cuentas, establecer una teoría materialista que actúe en desmedro de las ideas. Tampoco se trata, como observará el lector, de reivindicar una teoría de las ideas contra la materia. Lo que se pretende, considerando una contaminación cruzada entre lo sensible y lo inteligible, es rastrear otra verdad para aquello que ha sido considerado, especialmente por el (...) platonismo en sus diversas configuraciones, como lo inesencial frente al andamiaje trascendental de las ideas. En consecuencia, y a partir de un acercamiento pre-liminar, lo que se busca es permitir que los datos sensibles resuenen al interior de lo inteligible, y que lo hagan, además, de un modo no dialectizable.

En este artículo analizo los principales argumentos del libro Tauroética de Fernando Savater. Él afirma que existen argumentos morales a favor de las corridas de toros, por lo que ser taurino es una opción ética legítima. Aquí sostengo que está en un error y que los argumentos morales no tienen la fuerza que él les adjudica; puede haber razones económicas, políticas o de otro tipo a favor de las corridas, pero no hay razones morales. Afirmo, en cambio, que sí hay (...) razones morales fuertes en contra de las corridas que se basan en que los toros son objeto de consideración moral, es decir, tienen un estatus moral independiente de nuestros intereses. A partir de esta premisa examino y objeto, bajo una perspectiva ética, otros argumentos de Savater. (shrink)

ABSTRACT In the 1960s, when Dr. Belding Scribner discovered how to accomplish the process of dialysis in a repeated way, he could not imagine that in solving such a problem others as or more difficult would appear. Given the technological progress and the impossibility of assisting all patients through the most modern methods, the medical doctor often finds himself faced with the moral dilemma of choosing which patient in the waiting list will receive the treatment. This same dilemma is amplified (...) in the case of organ transplants. Professionals, students, professors of the juridical and health fields, and the population in general, were interviewed as a means of documenting the moral concepts and opinions surrounding this problem. In the reality in which we find ourselves, it seems to us that deciding who lives, and the responsibility for all the events that culminate in such decisions, is still a subject left open to discussion.

Let G V, E be a simple undirected complete graph with vertex and edge sets V and E, respectively. In this paper, we consider the degree-constrained k -minimum spanning tree problem which consists of finding a minimum cost subtree of G formed with at least k vertices of V where the degree of each vertex is less than or equal to an integer value d ≤ k − 2. In particular, in this paper, we consider degree values of d ∈ (...) 2,3. Notice that DC k MST generalizes both the classical degree-constrained and k -minimum spanning tree problems simultaneously. In particular, when d = 2, it reduces to a k -Hamiltonian path problem. Application domains where DC k MST can be adapted or directly utilized include backbone network structures in telecommunications, facility location, and transportation networks, to name a few. It is easy to see from the literature that the DC k MST problem has not been studied in depth so far. Thus, our main contributions in this paper can be highlighted as follows. We propose three mixed-integer linear programming models for the DC k MST problem and derive for each one an equivalent counterpart by using the handshaking lemma. Then, we further propose ant colony optimization and variable neighborhood search algorithms. Each proposed ACO and VNS method is also compared with another variant of it which is obtained while embedding a Q-learning strategy. We also propose a pure Q-learning algorithm that is competitive with the ACO ones. Finally, we conduct substantial numerical experiments using benchmark input graph instances from TSPLIB and randomly generated ones with uniform and Euclidean distance costs with up to 400 nodes. Our numerical results indicate that the proposed models and algorithms allow obtaining optimal and near-optimal solutions, respectively. Moreover, we report better solutions than CPLEX for the large-size instances. Ultimately, the empirical evidence shows that the proposed Q-learning strategies can bring considerable improvements.

Este ensayo se propone como una lectura tentativa de “Fors. Les mots anglés de Nicolas Abraham et Maria Torok”, texto que Jacques Derrida publicase en 1976 como prefacio al libro de Nicolas Abraham y Maria Torok, Cryptonymie. Le verbier de l’homme aux loups. A través de una suerte de mecanismo compositivo, se plantea que “Fors”, como operación bifaz de un doble cortante, pone en cuestión el campo de la institución psicoanalítica. A la vez, texto indispositivo e indigesto, expone el límite (...) de la asimilación introyectiva y cuestiona todo sistema de apropiación, neutralización, silenciamiento y/o recuerdo-interiorizante. Como un vómito interno, se trata, así, del “Yo” que porta al otro –al otro mortal en el yo y fuera del yo–, de aquello que instituye un fracaso en el cumplimiento de la asimilación. Se hacen lugar las cuestiones de la cripta, el lugar, la muerte –el otro como muerto vivo–, la cifra, el límite entre incorporación e introyección, el duelo imposible, así como un trazado de la operación del analista como poeta-traductor. “Fors” –fueros, salvo, excepto–, resta intraducible, indigerible, como marca una tópica fuera de sí. Deja la tarea de la traducción sin aforo, fuera de quicio, desaforada en una experiencia sin reserva ni fuero interno, infiel, desmedida, autoinmune, como un trabajo que no puede sino perder sus fueros, sus exenciones, sus privilegios. No estamos sino desaforados en traducción. Nuestra estancia en la transposición de la lengua: el desafuero. (shrink)

Los intereses del ingeniero y filósofo chileno Manuel Atria Ramírez recorren una variedad de temas y disciplinas, pero es en la filosofía de las matemáticas y de la física donde se centra una porción importante de su obra publicada. Tras una primera fase de juventud, de manifiesta impronta tomista, su pensamiento de madurez acusa el influjo de las grandes escuelas epistemológicas que prosperan durante la primera mitad del siglo XX. Además de ilustrar la recepción que se le daba por aquellos (...) años en el medio académico latinoamericano a las nuevas tendencias filosóficas europeas, pensamos que el conciso estilo expositivo del autor y su comprensión profunda de la físico-matemática y de su historia, tienen el mérito de plantear con frescura y originalidad la pregunta referida al fundamento último de las matemáticas, y de su vinculación con la realidad. En este artículo presentamos y analizamos las principales directrices de la propuesta epistemológica de Atria, e identificamos algunos puntos abiertos a investigaciones ulteriores. (shrink)

In this paper we provide a compact presentation of the verisimilitudinarian approach to scientific progress (VS, for short) and defend it against the sustained attack recently mounted by Alexander Bird (2007). Advocated by such authors as Ilkka Niiniluoto and Theo Kuipers, VS is the view that progress can be explained in terms of the increasing verisimilitude (or, equivalently, truthlikeness, or approximation to the truth) of scientific theories. According to Bird, VS overlooks the central issue of the appropriate grounding of scientific (...) beliefs in the evidence, and it is therefore unable (a) to reconstruct in a satisfactory way some hypothetical cases of scientific progress, and (b) to provide an explanation of the aversion to falsity that characterizes scientific practice. We rebut both of these criticisms and argue that they reveal a misunderstanding of some key concepts underlying VS. (shrink)

Previously, the author tried to show that some arguments in one of the two versions of Nicholas of Autrecourt’s Quaestio de intensione visionis are taken almost verbatim from the anonymous Tractatus de sex inconvenientibus. This paper concentrates on the arguments themselves in order to consider two main issues: the ‘translatability’ of limit decision problems, manifest in Autrecourt’s juxtaposition of questions de maximo et minimo, de primo et ultimo instanti, and the intension and remission of forms; the importance of Parisian discussions (...) of limit decision problems prior to the adoption of the new analytical languages developed at Oxford. Thus, the paper is divided in two sections, the first concerning some arguments of Autrecourt’s question, the second focusing on the link between one of Autrecourt’s arguments and the medieval tradition of commentaries on Aristotle’s De caelo, in which it is possible to find some antecedents of the analytical approach that later Parisian scholars would apply to these problems.

We provide a 'verisimilitudinarian' analysis of the well-known Linda paradox or conjunction fallacy, i.e., the fact that most people judge the probability of the conjunctive statement "Linda is a bank teller and is active in the feminist movement" (B & F) as more probable than the isolated statement "Linda is a bank teller" (B), contrary to an uncontroversial principle of probability theory. The basic idea is that experimental participants may judge B & F a better hypothesis about Linda as compared (...) to B because they evaluate B & F as more verisimilar than B. In fact, the hypothesis "feminist bank teller", while less likely to be true than "bank teller", may well be a better approximation to the truth about Linda. (shrink)

In this paper, we address the problem of truth approximation through theory change, asking whether revising our theories by newly acquired data leads us closer to the truth about a given domain. More particularly, we focus on “nomic conjunctive theories”, i.e., theories expressed as conjunctions of logically independent statements concerning the physical or, more generally, nomic possibilities and impossibilities of the domain under inquiry. We define both a comparative and a quantitative notion of the verisimilitude of such theories, and identify (...) suitable conditions concerning the (partial) correctness of acquired data, under which revising our theories by data leads us closer to “the nomic truth”, construed as the target of scientific inquiry. We conclude by indicating some further developments, generalizations, and open issues arising from our results. (shrink)

En cada contexto son diversas las formas de ser niña y niño. El objetivo de este artículo es reflexionar sobre los significados que implica el “ser migrante” para las niñas y los niños peruanos en Chile, considerando los procesos de integración social desde la perspectiva generacional y cómo cambia el concepto de infancia en contextos transnacionales. Mediante observación participante y entrevistas semiestructuradas con 16 niñas y niños peruanos, de 9 a 16 años de edad, se concluye que existe cierta idealización (...) de las formas de expresión de la infancia en Perú. Mientras que en Chile, las niñas y los niños migrantes sienten que las diferencias con sus pares chilenos se transforman en relaciones de desigualdad, conflicto y negociación. Además, la inserción escolar promueve la integración a determinados modelos de infancia construidos normativamente desde el mundo adulto y chileno, que dejan poco espacio para la diversidad cultural de las infancias transnacionales.

I present a formal ontological theory where the basic building blocks of the world can be either things or events. In any case, the result is a Parmenidean worldview where change is not a global property. What we understand by change manifests as asymmetries in the pattern of the world-lines that constitute 4-dimensional existents. I maintain that such a view is in accord with current scientific knowledge.

I argue for a four dimensional, non-dynamical view of space-time, where becoming is not an intrinsic property of reality. This view has many features in common with the Parmenidean conception of the universe. I discuss some recent objections to this position and I offer a comparison of the Parmenidean space-time with an interpretation of Heraclitus’ thought that presents no major antagonism.

This article provides a comparative and interpretative analysis of the emerging projects in Latin America after the crisis of the neoliberal modernity project. It offers a critical interpretation of the current tendencies in Latin American politics at the national level, while suggesting some hints to understand the current neoliberal crisis in Western countries after Trump’s electoral triumph. The purpose is to figure out the collective meanings behind the new national projects in Latin America (postcolonial indigeneity, confrontational populism, defective neoliberalism, and (...) social liberalism) that are constructing a new regional order. The work examines how the neoliberal modernity project came to be dominant in the late 1980s, only to enter into a period of crisis in the current century. That crisis, in turn, provides the basis for exploring four different alternative projects of modernity, based on the kind of rationality and agency promoted by them. (shrink)

There is widespread agreement that an adequate understanding of the nature of science (NOS) is a critical component of scientific literacy and a major goal in science education. However, we still do not know many specific details regarding how students and teachers learn particular aspects of NOS and what are the most important feature traits of instruction. In this context, the main objective of this review is to analyze articles from nine main science education journals that consider the teaching of (...) NOS to K-12 students, pre-service, and in-service science teachers in search of patterns in teaching and learning NOS. After reviewing 52 studies in nine journals that included data regarding participants’ views of NOS before and after an intervention, the main findings were as follows: (1) some aspects of NOS (empirical basis, observation and inference, and creativity) are easier to learn than others (tentativeness, theory and law, and social and cultural embeddedness), and subjective aspects of NOS and “the scientific method” seemed to be difficult for participants to understand; (2) the interventions most frequently lasted 5 to 8 weeks for students, one semester for pre-service teachers, and 1 year for experienced teachers; and (3) most of the interventions incorporated both decontextualized and contextualized activities. Given the substantial diversity in the methods and intervention designs used and the variables studied, it was not possible to infer a pattern of more-effective NOS teaching strategies from the reviewed studies. Future investigation should focus on (a) disentangling whether a difference exists between the easy and difficult aspects of learning NOS and formulating a theoretical explanation for distinguishing the two types of aspects and (b) assessing the effectiveness of different kinds of courses (e.g., history of science, NOS or informal) and strategies (e.g., hands-on vs. drama activities; SSI vs. HOS).

Este artículo busca revelar posibles cristalizaciones conceptuales que pudieran detener la reflexión en torno a los procedimientos de apropiación artística. Para ello, se reconsidera la idea de una supuesta modernidad artística pura y despojada de su pasado, y se evalúa la creencia tácita de que algún estilo, elemento u operación específica es, en sí mismo, suficiente para constatar la modernidad de las obras. Con todo, y en virtud de examinar su fuero moderno, distingue y examina si las propuestas artísticas reconvirtieron (...) los recursos disponibles, si edificaron versiones de algún estilo hegemónico, o si establecieron diatribas apegadas a su referente.

The aim of this research is to describe the levels of cognitive system processing that are present in the genre Worksheets of the academic discourse in economics as multimodal discourse. It was worked with a corpus of 68 Worksheets. This research is based on a qualitative paradigm, it has a non-Experimental design and it is an explorative and descriptive study. The data analysis shows that the Analysis and Knowledge Utilization are the levels of processing most worked in the Worksheets, both (...) levels correspond to the last levels of the cognitive system of the new taxonomy. These levels point to the elaboration of ideas in order to reach the application of the knowledge in the tasks. It was observed that the Worksheets used multisemiotic artifacts, mainly in tables and graphics. Finally, the multisemiotic artifacts are associated to levels of last order, in which it is required the knowledge of previous levels. It implicates the practice of divers cognitive abilities.
