What is sportsmanship? Following Keating, we may say that sportsmanship is conduct befitting a person involved in sports. This raises the question of what kind of activity exactly sport is. This is notoriously difficult to answer, but roughly speaking, sport is a rule-governed activity that is about excellence, an understanding of how to play the game, and, in competitive sports, winning. Accordingly, there are four elements of sportsmanship: fairness, equity, good form and the will to win. These four elements are (...) equally important and not reducible to one another. Yet, the will to win is in systematic conflict with the other three elements. Hence, sportsmanship is not only compromised of these four elements, but also requires that a balance be held between them. (shrink)

In this paper we prove that the free algebras in a subvariety equation image of the variety equation image of semi-Heyting algebras are directly decomposable if and only if equation image satisfies the Stone identity.

All paradoxes of self-reference seem to share some structural features. Russell in 1908 and especially Priest nowadays have advanced structural descriptions that successfully identify necessary conditions for having a paradox of this kind. I examine in this paper Priest’s description of these paradoxes, the Inclosure Scheme (IS), and consider in what sense it may help us understand and solve the problems they pose. However, I also consider the limitations of this kind of structural descriptions and give arguments against Priest’s use (...) of IS in favour of dialetheism. IS fails to identify sufficient conditions for having a paradox of self-reference. That means that, even if we identified a problem common to any reasoning satisfying IS, that problem would not explain why some of those reasonings are paradoxical and some others are not. Therefore IS cannot justify by itself the claim that some particular theory offers the best solution to the paradoxes of self-reference. We still need to consider aspects concerning the content and context of occurrence of every paradox. (shrink)

La recepción europea de Gómez Dávila comenzó a desplegarse de manera más amplia a partir de la lectura y difusión realizada por Franco Volpi. Este artículo alude a la manera como dicha lectura concretó las interpretaciones del colombiano, principalmente a la luz de una filosofía práctica y una perspectiva crítica. De dichas posturas, el italiano destaca la vocación vital y el carácter provocador del pensamiento de Gómez Dávila.

Economists use the term ‘stylized fact’ in many contexts, though the meaning of this phrase and the motivation for using such a concept is unclear. In this paper, we provide a philosophical analysis of stylized facts, which aims to be methodologically interesting and useful. While our framework applies to all principled uses of stylized facts, we illustrate its core features by applying it to Nicholas Kaldor's initial and exemplary use of stylized facts in growth economics.

Este artículo aborda el antiguo problema de la diferencia entre filosofía y poesía partiendo de una interpretación del arte narrativo personificado por Ulises en la Odisea. Una lectura del episodio de las Sirenas permite reconstruir la trama de voces diversas que compone el relato homérico y comprender la significación de esta estructura polifónica en el imaginario odiseico. Frente a la neta oposición entre autofonía y alofonía que propone la filosofía platónica, la poesía homérica implica una idea de heterofonía que apunta (...) más allá de una lógica binaria y sugiere la irreductibilidad de la voz poética a un juego entre extremos contrarios. La heterofonía consiste más bien en una voz figural que crea la «lógica difusa» del mundo ficcional mediante la neutralización de las diferencias entre sujetos enunciativos. (shrink)

This paper is devoted to the study of some subvarieties of the variety Qof Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Qis far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q 3 and we construct the lattice of subvarieties (...) (Q 3 ) of the variety Q 3. (shrink)

This paper is devoted to the study of some subvarieties of the variety Q of Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q subscript 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Q is far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q subscript 3 and we construct (...) the lattice of subvarieties lambda (Q subscript 3) of the variety Q subscript 3. (shrink)

Normal 0 21 false false false MicrosoftInternetExplorer4 One of the most important questions of moral philosophy is what makes a life a good life. A good way of approaching this issue is to watch the film Groundhog Day which can teach us a lot about what a good life consists in - and what not. While currently there are subjective and objective theories contending against each other about what a good life is, namely hedonism and desire satisfaction theories on the (...) one hand and objective list theories on the other, the film illustrates that at least one constituent of the good life can only be understood if we see it as having both an objective and a subjective side to it. Thus, the film shows that, in contrast to the beginning of the film, at the end the protagonist Phil has a good life insofar as that he finds something to do that suits him (the objective element), and comes to care deeply about it (the subjective element).

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most developed countries in the (...) world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.

The variety O2 of double Ockham algebras consists of the algebras (A ∨, ∧, f,g 0,1) of type (2,2,1,1,0,0) where (A; ∨, ∧,f, 0,1) and (A; ∨, ∧,g 0,1) are Ockham algebras. In [16], M. Sequeira introduced several subvarieties of O2. In this paper we give a construction of free double Ockham algebras on a partially ordered set. We also describe free objects for the subvarieties of O2 considered in [16].

La teoría moderna de la literatura surgió del encuentro, no siempre pacífico, entre la filosofía, la estética y la literatura bajo la influencia dominante de los programas idealistas y románticos. En el período que va desde la publicación del tratado de Schiller Sobre poesía ingenua y sentimental (1795) hasta la aparición de El nacimiento de la tragedia (1872) de Nietzsche, los conceptos poetológicos tradicionales fueron reelaborados en términos especulativos, sustancialistas y trascendentales. A través de una lectura comparada de textos filosóficos (...) y literarios, este libros propone una interpretación de conjunto en la que la teoría moderna de la literatura se caracteriza por una conciencia crítica cuyo ideal de transparencia reflexiva no cesa de conducir a diversas “formas de lo informe”.

In this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only with fictional (...) names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.

Este artículo analiza en primera instancia la lectura y consideración hermenéutica que Ernesto Volkening realiza de la obra de Nicolás Gómez Dávila. Tras una presentación de las pautas interpretativas que se dan en el Diario de lectura de Volkening, se considera luego el interés de losautores por la arquitectura y el urbanismo modernos, como claves para la crítica del modo de vida reificante del hombre actual. Posteriormente, se ilustran las pautas que abordan la historia y la historicidad, bajo la idea (...) de una comprensión hermenéutica gestada en los contextos, opuesta a cualquier determinismo y puesta en marcha bajo la impronta de la singularidad e individualidad.

In this work we provide a new topological representation for implication algebras in such a way that its one-point compactification is the topological space given in [1]. Some applications are given thereof.

La invitación hecha en el segundo semestre de 2022 para participar en este dosier de Co-herencia suponía, entonces, por un lado, el sometimiento de los comentarios de Volkening a la obra en proceso de Gómez Dávila a un primer escrutinio crítico y, por el otro, la apertura a la discusión sobre crítica literaria y el pensamiento en Colombia y a consideraciones sobre formas alternativas de escritura crítica, como las ofrecidas por el ensayo literario, el diario y los géneros marginales y (...) fragmentarios. El llamado invitaba a considerar la pertinencia de un tema lleno de posibilidades, que permite relacionar la pregunta por la escritura, la lectura, la institucionalización y la recepción literaria con las perspectivas que prodiga un diálogo entre dos intelectuales colombianos, actualizado gracias a su publicación casi medio siglo después. Surgía de este modo la opción de descubrir, no solo un objeto de estudio de interés, sino también nuevos caminos críticos para los problemas del campo literario, editorial e intelectual colombiano.

This paper presents a new two-dimensional Multiple-Choice Model accounting for Omissions (MCMO). Based on Thissen and Steinberg multiple-choice models, the MCMO defines omitted responses as the result of the respondent not knowing the correct answer and deciding to omit rather than to guess given a latent propensity to omit. Firstly, using a Monte Carlo simulation, the accuracy of the parameters estimated from data with different sample sizes (500, 1,000, and 2,000 subjects), test lengths (20, 40, and 80 items) and percentages (...) of omissions (5, 10, and 15%) were investigated. Later, the appropriateness of the MCMO to the Trends in International Mathematics and Science Study (TIMSS) Advanced 2015 mathematics and physics multiple-choice items was analyzed and compared with the Holman and Glas' Between-item Multi-dimensional IRT model (B-MIRT) and with the three-parameter logistic (3PL) model with omissions treated as incorrect responses. The results of the simulation study showed a good recovery of scale and position parameters. Pseudo-guessing parameters ( d ) were less accurate, but this inaccuracy did not seem to have an important effect on the estimation of abilities. The precision of the propensity to omit strongly depended on the ability values (the higher the ability, the worse the estimate of the propensity to omit). In the empirical study, the empirical reliability for ability estimates was high in both physics and mathematics. As in the simulation study, the estimates of the propensity to omit were less reliable and their precision varied with ability. Regarding the absolute item fit, the MCMO fitted the data better than the other models. Also, the MCMO offered significant increments in convergent validity between scores from multiple-choice and constructed-response items, with an increase of around 0.02 to 0.04 in R 2 in comparison with the two other methods. Finally, the high correlation between the country means of the propensity to omit in mathematics and physics suggests that (1) the propensity to omit is somehow affected by the country of residence of the examinees, and (2) the propensity to omit is independent of the test contents.

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

Cognitive diagnosis models (CDMs) allow classifying respondents into a set of discrete attribute profiles. The internal structure of the test is determined in a Q-matrix, whose correct specification is necessary to achieve an accurate attribute profile classification. Several empirical Q-matrix estimation and validation methods have been proposed with the aim of providing well-specified Q-matrices. However, these methods require the number of attributes to be set in advance. No systematic studies about CDMs dimensionality assessment have been conducted, which contrasts with the (...) vast existing literature for the factor analysis framework. To address this gap, the present study evaluates the performance of several dimensionality assessment methods from the factor analysis literature in determining the number of attributes in the context of CDMs. The explored methods were parallel analysis, minimum average partial, very simple structure, DETECT, empirical Kaiser criterion, exploratory graph analysis, and a machine learning factor forest model. Additionally, a model comparison approach was considered, which consists in comparing the model-fit of empirically estimated Q-matrices. The performance of these methods was assessed by means of a comprehensive simulation study that included different generating number of attributes, item qualities, sample sizes, ratios of the number of items to attribute, correlations among the attributes, attributes thresholds, and generating CDM. Results showed that parallel analysis (with Pearson correlations and mean eigenvalue criterion), factor forest model, and model comparison (with AIC) are suitable alternatives to determine the number of attributes in CDM applications, with an overall percentage of correct estimates above 76% of the conditions. The accuracy increased to 97% when these three methods agreed on the number of attributes. In short, the present study supports the use of three methods in assessing the dimensionality of CDMs. This will allow to test the assumption of correct dimensionality present in the Q-matrix estimation and validation methods, as well as to gather evidence of validity to support the use of the scores obtained with these models. The findings of this study are illustrated using real data from an intelligence test to provide guidelines for assessing the dimensionality of CDM data in applied settings. (shrink)

Although gains in generational intelligence test scores have been widely demonstrated around the world, researchers still do not know what has caused them. The cognitive stimulation and nutritional hypotheses summarize the several diverse potential causes that have been considered. This article analyses data for a sample of 499 children tested in 1930 and one equivalent sample of 710 children tested 72 years later, the largest gap ever considered. Both samples comprised children aged between 7 and 11 who were assessed by (...) the Draw-a-Man test in the city of Belo Horizonte, Brazil. Further, one additional sample of 132 children was assessed in 2004 in a rural area very similar in several diverse factors to the 1930 urban sample. The results are consistent with both the cognitive stimulation and the nutritional hypotheses. (shrink)
