En las dos entregas anteriores abordamos el inicio de la evolución del pensamiento matemático, desde el uso de herramientas matemáticas para problemas de cálculo concreto en la antigua Babilonia, pasando por el inicio de las matemáticas abstractas, las demostraciones y el nacimiento de la “geometría por la geometría” desde la visión religioso-filosófica de Platón y los pitagóricos, hasta la síntesis de ambas visiones en las matemáticas de la India, China y el mundo árabe, que fue la puerta de entrada de (...) las matemáticas a Europa, alrededor del siglo XV.

El artículo revisa las nociones sexo-género desde los límites y limitaciones impuestos por el biopoder hasta el posgénero, basándose en la Teoría farmacopornográfica de la filósofa española Beatriz Preciado. Se expone cómo, en la concepción de esta autora, el género es un dispositivo discursivo que escapa a las concepciones de alteridad sexual existentes y se conjuga tal idea con algunas corrientes críticas provenientes de los estudios culturales y el post estucturalismo. This paper reviews the sex-gender notions from the limits and (...) limitations imposed by the bio-power up to the post-gender, based on the pharmacopornographic theory proposed by the Spanish philosopher Beatriz Preciado. According to Preciado’s approach, gender is a discursive device that challenges the standard conceptions of sexual otherness, and this idea is blended with some critical trends from contemporary cultural studies and post-structuralism.

A partir de los años 90, la información estadística da cuenta de una masiva llegada de inmigrantes peruanos a la Región Metropolitana, concentrándose principalmente en las comunas de Santiago, Recoleta e Independencia. En este artículo se busca entender el efecto de los inmigrantes como factor de cambio en las áreas centrales de la capital, desde las transformaciones socio-espaciales, las que modifican el territorio, como el comportamiento de la población –evolución y distribución espacial-, y los cambios en la morfología y estructura (...) de éste. Lo anterior tiene sentido sobre la base teórica de la Nueva Geografía de las Migraciones, la cual explica el problema migratorio en el contexto de la Globalización y como ésta origina nuevos polos de atracción para la localización de esta población. Finalmente, se evalúan las condiciones de vida objetiva y percibida de los inmigrantes peruanos en cuanto a la calidad de vida y de satisfacción residencial. (shrink)

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Este trabajo analiza el vínculo entre Estado, capital y formas jurídicas. En primer lugar, se recupera una de las vertientes de la teoría marxista del Estado, aquella sintetizada en el debate sobre la derivación. En segundo término, y a la luz de dicha teoría, se avanza sobre el planteo realizado por Pashukanis acerca del vínculo entre mercancía y formas jurídicas. Por último y como corolario de los desarrollos anteriores, se justifica la perspectiva sobre el Estado capitalista en la que este (...) trabajo se apoya, aquella que lo toma como el representante político del capital total de la sociedad. El objetivo general de nuestro trabajo es extender el análisis que Pashukanis realiza para la mercancía al plano de abstracción correspondiente al capital. Particularmente, nos proponemos mostrar que las determinaciones que hacen enajenado al trabajo productor de mercancías se reproducen para el caso del capital, lo cual redunda en la forma necesariamente jurídica que toma la representación del capital total de la sociedad por parte del Estado.

Hannah Arendt’s work is notably ambiguous in handling the concept of will. On the one hand, willing appears as an anti-political faculty; on the other, it is named as the spring of political action. This paper asks what does this shift mean to her political theory —hoping that it could also help us to think our current political conflicts. The main argument is that will’s consistency with the plurality of public-political life becomes intelligible only if we have in mind its (...) contentious feature as well as its bonding role among the several faculties that compose a multiple self. However, the anti-political notion of the will as a command that imposes itself as a sovereign decision seems hard to avoid. I conclude by suggesting that Arendt’s reappraisal removes its arbitrary and violent character by means of what she calls the transformation of will into love. (shrink)

El Test de Turing es un método tan controvertido como desafiante en Inteligencia Artificial. Se basa en la imitación de la conducta lingüística de humanos, y tiene como objetivo recabar evidencia empírica en favor de la tesis de que las máquinas programadas podrían pensar. Alan Turing, su creador, ha sido catalogado como conductista por la mayor parte de los comentaristas. En este capítulo muestro que no lo es. Por el contrario, Turing es un funcionalista, porque todo el énfasis del juego (...) de la imitación está en el engaño de la máquina hacia los humanos. Por ello el género es importante en dicho juego, al menos en su versión preliminar. (shrink)

The technique of forcing is almost ubiquitous in set theory, and it seems to be based on technicalities like the concepts of genericity, forcing names and their evaluations, and on the recursively defined forcing predicates, the definition of which is particularly intricate for the basic case of atomic first order formulas. In his [3], the first author has provided an axiomatic framework for set forcing over models of $\mathrm {ZFC}$ that is a collection of guiding principles for extensions over which (...) one still has control from the ground model, and has shown that these axiomatics necessarily lead to the usual concepts of genericity and of forcing extensions, and also that one can infer from them the usual recursive definition of forcing predicates. In this paper, we present a more general such approach, covering both class forcing and set forcing, over various base theories, and we provide additional details regarding the formal setting that was outlined in [3].

The minimal ordinal-connection axiom $$MOC$$ was introduced by the first author in R. Freire. (South Am. J. Log. 2:347–359, 2016). We observe that $$MOC$$ is equivalent to a number of statements on the existence of certain hierarchies on the universe, and that under global choice, $$MOC$$ is in fact equivalent to the $${{\,\mathrm{GCH}\,}}$$. Our main results then show that $$MOC$$ corresponds to a weak version of global choice in models of the $${{\,\mathrm{GCH}\,}}$$ : it can fail in models of the (...) $${{\,\mathrm{GCH}\,}}$$ without global choice, but also global choice can fail in models of $$MOC$$.

This paper begins the study of first-order functions, which are a generalization of truth-functions. The concepts of truth-table and systems of truth-functions, both introduced in propositional logic by Post, are also generalized and studied in the quantificational setting. The general facts about these concepts are given in the first five sections, and constitute a “general theory” of first-order functions. The central theme of this paper is the relation of definition among notions expressed by formulas of first-order logic. We emphasize that (...) logic is not concerned only with the consequence relation among notions expressed by formulas. It also attends to the relation of definition among notions, where a notion is defined from other notions. Sections 5 and 6 deal exclusively with the relation of definition among notions expressed by formulas of first-order logic. In these sections, we study the systems of first-order functions, which are the sets of first-order functions closed under definitions. Sections 7 and 8 are concerned with the relativization of first-order functions to a class of structures. The relativization to a class of structures is a fundamental operation which is used in order to relate the theory of first-order functions with set theory and first-order model theory, a subject which we have barely scratched the surface. The apparatus developed in this paper enables us to define what is a vehicle for the foundation of classical mathematics in set theory, and, in Sect. 8, we prove that first-order logic with one binary predicate variable is not a minimal vehicle for the foundation of classical mathematics in set theory. Sections 9 and 10 introduce further operations and ideals of first-order functions. Besides some results on the influence of the arguments of a first-order function, a result about definability is proved in Sect. 10.1. It is this theorem that provides necessary and sufficient conditions for a first-order function to be in a finitely generated ideal. In Sect. 11, this result is applied to the problem of predicate definability in classes of structures, the problem with which Beth’s theorem dealt in the case of elementary classes. (shrink)

The aim of the present paper is to provide a robust classification of valid sentences in set theory by means of existence and related notions and, in this way, to capture similarities and dissimilarities among the axioms of set theory. In order to achieve this, precise definitions for the notions of productive and nonproductive assertions, constructive and nonconstructive productive assertions, and conditional and unconditional productive assertions, among others, will be presented. These definitions constitute the result of a semantical analysis of (...) the notions involved. The conceptual clarification developed here results in a classification of valid sentences of set theory that goes against the standard view that extensionality is not an existence assertion.

This paper presents and discusses the most influential attempts to characterize physicalism without postulating relations of identity between the physical and the prima facie non-physical. The first section deals with a possible criticism that these attempts are misguided, since they contradict the physicalist slogan “everything there is physical.” In the second section, I elucidate the different formulations of the physicalist supervenience claim, and argue that none of them consists in an adequate characterization of physicalism. Three reasons are given in favor (...) of this conclusion: their compatibility with forms of dualism ; the fact that the supervenience relation is left unexplained; and Kim’s causal exclusion argument, which asserts that merely supervenient entities must be epiphenomenal. The third section presents the general features of another identity-independent attempt to characterize physicalism, namely realization physicalism. According to this view, tokens of prima facie non-physical types are realized by tokens of strictly physical types performing functional roles that specify the nature of the former. The third section also shows how realization physicalism deals with the objections that make physicalist supervenience claims inadequate for characterizing physicalism. Resumo O artigo apresenta e discute as tentativas mais influentes de caracterizar o fisicalismo sem postular relações de identidade entre o que é físico e o que é prima facie não físico. A primeira seção trata da possível crítica de que essas tentativas são equivocadas, porque contradizem o bordão fisicalista “tudo o que existe é físico”. Na segunda seção, elucido as diferentes formulações da tese fisicalista da superveniência, e argumento que nenhuma delas consiste em uma caracterização adequada do fisicalismo. Três razões são oferecidas em favor dessa conclusão: sua compatibilidade com formas de dualismo ; o fato de que a relação de superveniência é mantida sem explicação; e o argumento de Kim da exclusão causal, segundo o qual entidades meramente supervenientes devem ser epifenomenais. A terceira seção apresenta os aspectos gerais de outra tentativa de caracterizar o fisicalismo independente da identidade, a saber, o fisicalismo de realização. De acordo com essa posição, ocorrências de tipos prima facie não físicos são realizadas por ocorrências de tipos físicos quando estes executam os papéis funcionais que especificam a natureza dos primeiros. A terceira seção também revela como o fisicalismo de realização lida com as objeções que tornam as teses fisicalistas da superveniência inadequadas para a caracterização do fisicalismo. (shrink)

Resumen: El presente trabajo investiga la forma en que las ciencias sociales, principalmente chilenas, están respondiendo a las dispares demandas que reciben actualmente y que consisten en aportar a la comprensión crítica de fenómenos relevantes para la sociedad y adecuarse a las recientes transformaciones en la forma de producir y comunicar conocimiento científico incorporando mayores niveles de internacionalización, globalización, especialización y complejización. Para ello se realiza una revisión sistemática de la producción científica publicada sobre el movimiento estudiantil chileno, que constituye (...) uno de los movimientos sociales más relevantes de la historia reciente de Chile. Se sistematizaron 149 publicaciones editadas entre el año 2000 y el 2016. Los resultados muestran que la capacidad de las ciencias sociales chilenas para abordar estas demandas contradictorias es parcial, pues sus análisis críticos tienden a ser uniformes y de alcance temporal limitado, mientras que sus estudios empíricos no siempre poseen los niveles de internacionalización y complejidad demandados actualmente para participar en los circuitos internacionales de publicación.: The present work investigates the way in which social sciences, mainly Chilean, are responding to different demands that they are currently receiving and that consist of contribute to the critical understanding of phenomena relevant to society and adapt to recent transformations in the way of producing and communicating scientific knowledge, incorporating higher levels of internationalization, globalization, specialization and complexity. To this end, a systematic review of the scientific production published on the Chilean student movement is made. This movement is one of the most relevant in Chile's recent history. 149 publications were systematized, published between 2000 and 2016. The results show that the capacity of the Chilean social sciences to deal with these contradictory demands is partial, since their critical analyzes tend to be uniforms and limited in time, while their empirical studies do not always have the levels of internationalization and complexity currently demanded in international publishing circuits.

The common notion of artifacts characterizes them as the products of successful activities of their makers, guided by intentions that such objects would instantiate certain features, such as their specific functions. Many counterexamples, however, reveal the unsuitability of the common notion. In the face of this acknowledgment, the paper explores the possibility that features of artifacts, and more specifically, the possession of their functions, may arise, at least partially, from collective assignments. In order to achieve the mentioned goal, the paper (...) critically examines some notions and theses put forward by John Searle and others. Its main result, however, consists in offering and elucidating an original thesis, namely, that the functions of many artifacts would be maintained, partially, by forms of continuous collective intentionality, which can involve conscious or unconscious, active or inactive collective intentional states. Keywords: Artifacts, assignment of function, collective intentionality, maintenance of function. (shrink)

Resumo Palavras-chave Keywords : Children’s literature. Music. Pedagogical practice : This article’s main purpose is to present a few possibilities of work with activities that involve pieces of children’s literature and music in the perspective of Children’s Education and first years of Primary School. As theoretical support, the paper presents several studies from authors such as Brito (2003), Ponso (2008), Souza (2006), Torres and Gallicchio (2004), among others who suggest developing activities of sound exploration through audition/appreciation and improvise/ sound (...) editing from some texts and books of children’s literature. A conclusion has been reached that the proposal of activities transforming words in music enables readers to experiment different sounds to compose the soundtrack of stories. Besides, when selecting a diversified repertoire with several texts, possibilities are created to the students to tell, recount and sing varied stories, allowing, thus, the entrance of different social voices. : Literatura Infantil. Música. Prática pedagógica. : O objetivo maior deste artigo é o de apresentar algumas possibilidades de trabalho com atividades que envolvam obras de literatura infantil e músicas, na perspectiva da Educação Infantil e Séries Iniciais do Ensino Fundamental.

Constatou-se que a proposta de atividades, transformando palavras em músicas, possibilita interpelar os leitores a experimentarem diferentes sons para compor a trilha sonora de histórias. Além disso, ao selecionar um repertório diversificado com vários textos, criam-se possibilidades aos alunos para contarem, recontarem e cantarem variadas histórias, permitindo, dessa maneira, a entrada de diferentes vozes sociais.

En este artículo argumentamos que la naturaleza pública o privada de la educación tiene una incidencia directa en las instituciones que conforman la realidad social. Para sustentar lo anterior, en primer lugar discutimos cómo, según Searle, habitamos un mundo de instituciones gobernadas por reglas y poderes deónticos, ontológicamente irreductibles. Luego, postulamos que la intencionalidad colectiva requiere de la confianza para mantenerse, y esta aumenta cuando gobiernan reglas y poderes deónticos en circunstancias normales. Finalmente, planteamos que la educación pública es una (...) institución que, a diferencia de la privada, privilegia el espacio de lo común. Sócrates es un ejemplo de esto, al proponer una filosofía que no solo busca la verdad, sino que además privilegia el reconocimiento de la ley por sobre la satisfacción inmediata de deseos e inclinaciones personales. De todo esto se explica el círculo virtuoso: la educación pública, al ser inclusiva y beneficiar a todos, potencia las instituciones sociales que tutelan ese interés y, dentro de ellas, el servicio público.

In previous research, acoustic characteristics of the male voice have been shown to signal various aspects of mate quality and threat potential. But the human voice is also a medium of linguistic communication. The present study explores whether physical and vocal indicators of male mate quality and threat potential are linked to effective communicative behaviors such as vowel differentiation and use of more salient phonetic variants of consonants. We show that physical and vocal indicators of male threat potential, height and (...) formant position, are negatively linked to vowel space size, and that height and levels of circulating testosterone are negatively linked to the use of the aspirated variant of the alveolar stop consonant /t/. Thus, taller, more masculine men display less clarity in their speech and prefer phonetic variants that may be associated with masculine attributes such as toughness. These findings suggest that vocal signals of men’s mate quality and/or dominance are not confined to the realm of voice acoustics but extend to other aspects of communicative behavior, even if this means a trade-off with speech patterns that are considered communicatively advantageous, such as clarity and indexical cues to higher social class.

Inspired by Castañeda (1966, 1968), Perry (1979) and Lewis (1979) showed that a specific variety of singular thoughts, thoughts about oneself “as oneself” – de se thoughts, as Lewis called them – raise special issues, and they advanced rival accounts. Their suggestive examples raise the problem of de se thought – to wit, how to characterize it so as to give an accurate account of the data, tracing its relations to singular thoughts in general. After rehearsing the main tenets of (...) two contrasting accounts – a Lewisian one and a Perrian one – in the first section of this paper, in the second I will present a proposal of my own, which is a specific elaboration of the Perrian account. In the first section I will indicate some weaknesses of Perry’s presentation of his view; the proposal I will articulate in the second overcomes them. I will conclude with a brief discussion of reasons for preferring one or another account, in particular regarding the issue of the communication of de se thoughts. (shrink)

An individual's health, genetic, or environmental-exposure data, placed in an online repository, creates a valuable shared resource that can accelerate biomedical research and even open opportunities for crowd-sourcing discoveries by members of the public. But these data become “immortalized” in ways that may create lasting risk as well as benefit. Once shared on the Internet, the data are difficult or impossible to redact, and identities may be revealed by a process called data linkage, in which online data sets are matched (...) to each other. Reidentification, the process of associating an individual's name with data that were considered deidentified, poses risks such as insurance or employment discrimination, social stigma, and breach of the promises often made in informed-consent documents. At the same time, re-ID poses risks to researchers and indeed to the future of science, should re-ID end up undermining the trust and participation of potential research participants. The ethical challenges of online data sharing are heightened as so-called big data becomes an increasingly important research tool and driver of new research structures. Big data is shifting research to include large numbers of researchers and institutions as well as large numbers of participants providing diverse types of data, so the participants’ consent relationship is no longer with a person or even a research institution. In addition, consent is further transformed because big data analysis often begins with descriptive inquiry and generation of a hypothesis, and the research questions cannot be clearly defined at the outset and may be unforeseeable over the long term. In this article, we consider how expanded data sharing poses new challenges, illustrated by genomics and the transition to new models of consent. We draw on the experiences of participants in an open data platform—the Personal Genome Project—to allow study participants to contribute their voices to inform ethical consent practices and protocol reviews for big-data research.

Sound symbolism refers to non-arbitrary associations between word forms and meaning, such as those observed for some properties of sounds and size or shape. Recent evidence suggests that these connections extend to emotional concepts. Here we investigated two types of non-arbitrary relationships. Study 1 examined whether iconicity scores (i.e. resemblance-based mapping between aspects of a word’s form and its meaning) for words can be predicted from ratings in the affective dimensions of valence and arousal and/or the discrete emotions of happiness, (...) anger, fear, disgust and sadness. Words denoting negative concepts were more likely to have more iconic word forms. Study 2 explored whether statistical regularities in single phonemes (i.e. systematicity) predicted ratings in affective dimensions and/or discrete emotions. Voiceless (/p/, /t/) and voiced plosives (/b/, /d/, /g/) were related to high arousing words, whereas high arousing negative words tended to include fricatives (/s/, /z/). Hissing consonants were also more likely to occur in words denoting all negative discrete emotions. Additionally, words conveying certain discrete emotions included specific phonemes. Overall, our data suggest that emotional features might explain variations in iconicity and provide new insight about phonemic patterns showing sound symbolic associations with the affective properties of words.

This article proposes an exposition and analysis of perceptions intrinsic to rituals carried out with the use of the jurema plant, especially when mixed with Syrian rue (juremahuasca) in contexts of contemporary esoteric re-actualizations in Brazil. These rituals are conducted by people who look at jurema as a spiritual path, once acquainted with its psychedelic properties. We highlight the mystical attributes and the cultural bricolage elaborated by these individuals, who conduct ceremonies in ritual spaces in which participants experience altered states (...) of perception and consciousness. Considered as an entheogen, jurema leads to states of mystical transformation in people. Such personal changes are often considered by users as the rhetoric of healing. Life stories and ethnographic contexts form the background of the article, which seeks to advance understandings about jurema based on speculations around the intertwining of the themes of consciousness, mysticism, and healing.

De se attitudes seem to play a special role in action and cognition. This raises a challenge to the traditional way in which mental attitudes have been understood. In this chapter, we review the case for thinking that de se attitudes require special theoretical treatment and discuss various ways in which the traditional theory can be modified to accommodate de se attitudes.
