All spaces are assumed to be Tychonoff. Given a realcompact space X, we denote by $\mathsf {Exp}(X)$ the smallest infinite cardinal $\kappa $ such that X is homeomorphic to a closed subspace of $\mathbb {R}^\kappa $. Our main result shows that, given a cardinal $\kappa $, the following conditions are equivalent: • There exists a countable crowded space X such that $\mathsf {Exp}(X)=\kappa $. • $\mathfrak {p}\leq \kappa \leq \mathfrak {c}$. In fact, in the case $\mathfrak {d}\leq \kappa \leq \mathfrak (...) {c}$, every countable dense subspace of $2^\kappa $ provides such an example. This will follow from our analysis of the pseudocharacter of countable subsets of products of first-countable spaces. Finally, we show that a scattered space of weight $\kappa $ has pseudocharacter at most $\kappa $ in any compactification. This will allow us to calculate $\mathsf {Exp}(X)$ for an arbitrary (that is, not necessarily crowded) countable space X. (shrink)

Griffiths and Matthewson (2018) employ the selected effects theory to contend that disease involves the impairment of the normal functioning of biological items. Since the selected effects theory focuses on the past effects of those items, I refer to their proposal as “aetiological naturalism”. In this paper, I argue that aetiological naturalism cannot constitute an adequate theory of disease. This is due to the fact that the selected effects theory, which lies at the heart of aetiological naturalism, is flawed. One (...) promise of the selected effects theory is indeed that it is able to account for our normative intuitions about dysfunctional biological items by grounding them on the concept of natural selection incorporated in the selected effects theory itself, where this promise rests upon its claim that appealing to the fitness-enhancing effect of biological items can always explain why they persisted in a population. However, I contend that the naturalisation of normativity cannot be cashed out in terms of biological items’ past effects by discussing two biological phenomena: phenotypic plasticity and negative frequency-dependent selection. I illustrate that in both cases the selected effects theory cannot recognise adaptive items as having a selected effects function, therefore preventing the possibility to assign them any dysfunction. The normative force of the selected effects theory is consequently much diminished, leading in turn to a weakening of aetiological naturalism, given that such project actually relies on the assumed normative force of the selected effects theory itself.

The present study investigated the mediating role of conceptions of learning in the relationship between metacognition and academic outcomes among middle school students. The self-report ‘Learning Conceptions Questionnaire’ (LCQ) and ‘Metacognitive questionnaire on the method of study’ (QMS) were administered to 136 middle school students and their academic outcomes were collected. Correlation analyses revealed that within metacognition only self-assessment was positively correlated with academic outcomes. Mediation analysis indicated that a conception of learning as internal attribution of success and failure was (...) significantly involved as mediator in the relationship between metacognition and academic achievements. The present study permitted to advance our knowledge about the relationship between metacognition and academic achievements and it opened the way to practical implications. (shrink)

Este estudo reflete sobre fundamentos epistemológicos da ciência da informação. Segue métodos compatíveis com a reflexão epistemológica, baseia-se numa pesquisa bibliográfica de autores e temáticas relevantes à construção do argumento. Analisa os trabalhos recuperados mediante a interpretação crítica de suas teses. A hipótese que mobiliza a discussão é a de que a teoria objetiva do conhecimento, da qual resulta a noção de ‘mundo 3’ de Karl Popper, tem consequências relevantes para uma concepção epistemológica da informação e, consequentemente, da ciência da (...) informação. Apresenta uma interpretação do ‘mundo 3’, em sintonia com os fundamentos da ciência da informação, com base no exame das evidências encontradas nas obras do próprio Popper. Trabalhos de autores da ciência da informação que se referem às teorias de Popper são discutidos, a fim de fundamentar a linha interpretativa do argumento. Conclui-se por uma identificação entre o ‘mundo 3’ de Popper e a cultura humana. Disto resulta a noção de um processo evolutivo da informação, no qual a ciência da informação desempenha um papel relevante. Nesta imagem, a ciência da informação teria a função de moldar o ambiente, substituindo a informação desordenada pela informação cultivada e criada para interesses produtivos humanos. (shrink)

El objetivo de este artículo es mostrar la existencia de un aspecto durkheimiano en la filosofía de la religión de William James, aspecto habitualmente inadvertido en las interpretaciones corrientes de su obra. Para ello mostraré cómo subyace en Las variedades de la experiencia religiosa la prototípica distinción durkheimiana entre lo sagrado y lo profano como rasgo esencial de la religión. The purpose of this article is to demonstrate the existence of a Durkheimian aspect in William James' philosophy of religion, an (...) aspect that has gone unnoticed in the usual interpretations of his work. To this effect, the article shows how Durkheim's prototypical distinction between sacred and profane underlies The Varieties of Religious Experience as an essential feature of religion. (shrink)

El siguiente trabajo se circunscribe en los dilemas que vivencia el profesional, el intelectual que se posiciona en una trinchera del conocimiento que tiene causa común con el enfrentamiento del modelo económico-social actual. Analiza la pugna que existe entre la satisfacción de necesidades de la institución donde trabaja y aquellas necesidades explicitas y latentes del grupo humano donde materializa el ejercicio disciplinario La finalidad, entonces, es sumarse al proyecto social que llama a la militancia en el campo, a la resignificación (...) del compromiso intelectual con la clase oprimida, a la lucha que deben dar en el campo los intelectuales, no solo contra el poder simbólico, sino en contra de la razón neoliberal.

The selected effects theory is supposed to provide a fully naturalistic basis for statements about what biological traits or processes are for without appeal to final causes or intelligent design. On the selected effects theory, biologists are allowed to say, for instance, that hindwing eyespots on butterfly wings serve to deflect predators’ attacks away from vital organs because a similar fitness-enhancing effect explains why eyespots themselves were favoured by natural selection and persisted in the population. This is known as the (...) explanatory dimension of the selected effects theory. According to it, appealing to the fitness-enhancing effect of a certain trait or process is sufficient to explain its current presence in a population, namely, why it persisted and still exists in that population. In this paper, however, I will call such a claim into question, and I will do so by discussing a mathematical Hawk-Dove example and a real case scenario taken from evolutionary biology, that of Perissodus microlepis. These are scenarios in which the selective filter does not allow variants with the highest fitness at a certain moment to prevail over their available alternatives. In similar cases, I will argue, citing fitness-enhancing effects does not represent an adequate explanation of what happens in the population, undermining the explanatory dimension of the selected effects theory.

Este artículo examina las diferentes conceptualizaciones del sistema cognitivo de los docentes, desde la perspectiva socioconstructivista. Aborda la cognición como una base conceptual, personal, subjetiva y dinámica que tiene un impacto significativo en la actuación docente y en el proceso de cambio en educación. El proceso de exploración de la cognición docente puede ayudar a enriquecer la conceptualización sobre el proceso didáctico, y, además, puede servir como base para la autoevaluación docente, componente importante del desarrollo profesional en la Educación Superior.

The T lymphocyte receptor for antigen, which operates in conjunction with gene products of the major histocompatibility complex (MHC), is a molecular complex comprised of five polypeptide chains. Both the 49 kDa alpha and 43 kDa beta chains are immunoglobulin‐like and thus contain variable domains responsible for ligand binding. In contrast, the 20–25 kDa T3 gamma, delta and epsilon chains are monomorphic structures presumably involved in transmembrane signalling. The alpha and beta subunits are disulfide bonded to each other and held (...) in noncovalent association with the T3 chains. T3‐Ti receptor crosslinking leads to conformational modification of a second T lineage specific molecule, termed the 50 kDa T11 structure which in turn leads to protein kinase C activation, elevation in intracytoplasmic free calcium and Na+/H+ antiport stimulation.

Cet article expose le problème de l’identité personnelle chez Paul Ricoeur, à partir de Temps et récit et Soi-même comme un autre , en abordant, succinctement, des positions philosophiques qui affirment ce que Ricoeur caracterise comme identité en tant que permanence dans le temps (mêmeté), au contraire de l’identité en tant que mutable et diverse dans le temps (ipséité), qui va à la rencontre de sa thèse de l’identité narrative. Ensuite, nous indiquons la limitation de la narrative pour rendre compte (...) du problème de l’identité personnelle devant le possible effacement de soi-même dans le cadre narratif et persévérance dans le cadre éthique avec le concepte de promesse. Enfin, l’article est conclu avec l’exposition de l’approximation que Ricoeur réalise du concept de promesse en tant que speech act et comme pouvoir de promettre , et le rapport avec le concept de responsabilité qui découle de cela.

El objetivo principal de este artículo es defender, de acuerdo con A. John Simmons, un punto de vista que, normativamente, propone el consentimiento como condición necesaria de legitimidad y fundamento de la obligación política. Pero, descriptivamente, entiende que tal consentimiento, en tanto que autorización personal y voluntaria, todavía no ha tenido lugar en ninguna sociedad, ni siquiera democrática.

This article discusses how the Generic Model of Psychotherapy can help to organize the psychotherapy research and the knowledge in the field of psychotherapy for sexual and gender minority patients. The structure that this traditional model provides is a good foundation for research in this field, inasmuch as it stresses macrosocial aspects that determine the provision of psychotherapy and contextualize its outcomes. Each one of the main components offered by the Generic Model of Psychotherapy – Determinants, Processes, and Consequences – (...) are specified for psychotherapy with LGBT patients and are illustrated with a selection of already existing research in the field of sexual minorities; they are also stress areas marked by knowledge gaps that require future developments. In addition, a set of questions are proposed to contribute to new studies, including the clinical implications that can be derived from this model. (shrink)

El artículo aborda el concepto de subjetivación como otro modo de resistencia al poder desde el pensamiento de Michel Foucault. Para esto instala el problema en las dimensiones del saber/poder y su funcionamiento en los dispositivos concretos, y como éstos remiten a un diagrama de fuerzas puras. Teniendo en consideración estos antecedentes, el texto intenta desplazar la resistencia hacia otro lugar, el que va más allá de la clásica relación poder/contrapoder; es en este sentido que la resistencia aparece como un (...) pliegue de la fuerza que encuentra en la subjetivación una efectuación que disloca la visión común de este concepto. Palabras clave: Resistencia - Subjetivación - Diagrama - Dispositivos. (shrink)

Dentro del organigrama de la industria musical, las casas discográficas y emisoras radiales generan su dependiente relación por medio de la música grabada. En nuestro país, entre los años 1964-67, los sellos fonográficos nacionales lograron que muchos de sus artistas fueran invitados a las estaciones radiales por los disc-jockeys más famosos para promocionar sus discos. No obstante, se produjeron constantes discusiones y polémicas cuando las radios no difundieron, o bien, silenciaron muchos registros discográficos de intérpretes criollos, puesto que consideraron que (...) las casas disqueras plasmaron mucha música que no merecía ser editada. Las emisoras radiales se defendieron argumentando que, prácticamente,no valía la pena ser dueño de un pequeño sello discográfico, ni invertir en promoción, ni conseguir discos de éxito cuando sus artistas no podían demostrar su talento en directo. En otras palabras, las radios chilenas exigieron calidad integral al artista nacional: hit radial y presentación en vivo. (shrink)

The deep operation of androcentrism in scientific argumentation demands recognition as a form of fallacy. On Walton’s account, fallacies are serious mistakes in argumentation that employ presumptions acceptable in other circumstances. There are only isolated cases in which androcentric pre-sumptions are acceptable, and I argue that androcentrism affects an overarching theme of generalization in science rather than an isolated scheme. Androcentrism is related to other ways of treating privileged people as exemplary humans, whose negative impact on processes of argumentation can (...) be described as the fallacy of “appeal to the standard.”.

El problema central de este artículo es aproximarnos a la relación que se dio entre el accionar de la Gestapo, la generación y mantención de un orden que debía eliminar y neutralizar a los “enemigos” del “pueblo alemán”, comunistas y católicos de oposición, y el aseguramiento de “su bienestar” durante los primeros años de la dictadura nazi. La Gestapo fue uno de los instrumentos tempranos para asegurar la neutralización de las resistencias al proyecto nacionalsocialista. Involucraba un nacionalismo extremo, que se (...) movilizaba racial e ideológicamente en pos de la construcción de un orden social que asegurara las supuestas condiciones de vida y supremacía de los alemanes arios. Al mismo tiempo se busca recordar que históricamente la oposición existió, más allá de su incapacidad y fracaso. Si bien la dictadura tuvo aliados o cómplices en su camino de terror, también se debe mantener en la memoria histórica que hubo resistencias: no todos fueron cómplices de la dictadura nazi. (shrink)

My discussion addresses the differences between analytic and continental philosophy concerning the use of logic and exact reasoning in philosophical practice. These differences are mainly examined in the light of the controversial dominance of Hegel's concept of logic (and theory of concept) in twentieth-century continental philosophy. The inquiry is developed in two parts. In the first (Sections 1-2), I indicate some aspects of the analytic-continental divide, pointing to the role that the topic 'logic and philosophy' plays in it. In the (...) second part (Sections 3-6), I give a short account of the views of logic which are typical of the three main trends of continental philosophy (see Table 1). I also suggest how, with the aid of some typical analytical devices, some continental 'anti-logical' attitudes may be corrected, on their own terms. (shrink)
