The poverty of stimulus argument is one of the most controversial arguments in the study of language acquisition. Here we follow previous approaches challenging the assumption of impoverished primary linguistic data, focusing on the specific problem of auxiliary (AUX) fronting in complex polar interrogatives. We develop a series of corpus analyses of child-directed speech showing that there is indirect statistical information useful for correct auxiliary fronting in polar interrogatives and that such information is sufficient for distinguishing between grammatical and ungrammatical (...) generalizations, even in the absence of direct evidence. We further show that there are simple learning devices, such as neural networks, capable of exploiting such statistical cues, producing a bias toward correct AUX questions when compared to their ungrammatical counterparts. The results suggest that the basic assumptions of the poverty of stimulus argument may need to be reappraised. (shrink)

It is widely assumed that language in some form or other originated by piggybacking on pre-existing learning mechanism not dedicated to language. Using evolutionary connectionist simulations, we explore the implications of such assumptions by determining the effect of constraints derived from an earlier evolved mechanism for sequential learning on the interaction between biological and linguistic adaptation across generations of language learners. Artificial neural networks were initially allowed to evolve “biologically” to improve their sequential learning abilities, after which language was introduced (...) into the population. We compared the relative contribution of biological and linguistic adaptation by allowing both networks and language to change over time. The simulation results support two main conclusions: First, over generations, a consistent head-ordering emerged due to linguistic adaptation. This is consistent with previous studies suggesting that some apparently arbitrary aspects of linguistic structure may arise from cognitive constraints on sequential learning. Second, when networks were selected to maintain a good level of performance on the sequential learning task, language learnability is significantly improved by linguistic adaptation but not by biological adaptation. Indeed, the pressure toward maintaining a high level of sequential learning performance prevented biological assimilation of linguistic-specific knowledge from occurring. (shrink)

Multiple constraints, including semantic, lexical, and usage-based factors, have been shown to influence dative alternation across different languages. This work explores whether fine-grained statistics and semantic properties of the verb affect the acceptability of dative constructions in Spanish. First, a corpus analysis reveals that verbs of different semantic classes occur naturally in alternative dative constructions, a pattern quite different from English. The fact that dative alternation appears independent of semantic classes challenges traditional semantic-based approaches. Second, acceptability rating tasks reveal that (...) dative constructions containing highly entrenched word combinations and frequent word order are judged more acceptable regardless of the verbs' semantics. The results are interpreted in favor of usage-based accounts: Acceptability of dative constructions may be language-specific and depend on patterns of use and conventionalization. (shrink)

Dentro de la academia los estudios sobre el juego suelen ser marginados o subestimados como cuestiones secundarias al pensamiento, o como espacios de discusión dirigidos solamente al ocio contemplativo. Sin embargo, en oposición a este tipo de inferencias nos dedicaremos enteramente a reivindicar el papel del juego como fenómeno existencial fundamental en la pregunta por el ser y su relación con el mundo. En el presente trabajo propondremos un cruce lúdico y metafísico entre dos reconocidos pensadores: Carlos Astrada, filósofo argentino, (...) y Eugen Fink, filósofo alemán. Ambos autores comparten la herencia heideggeriana que pondrán en discusión y que servirá como hilo conductor del diálogo teórico sobre el carácter ontológico del juego. (shrink)

El siguiente trabajo parte del análisis de dos obras literarias que vieron su aparición en el Siglo XXI: Historia de los abuelos que no tuve, de Ivan Jablonka, y El gueto interior, de Santiago Amigorena, dos novelas que toman como eje temático y vertebrador de las narraciones la búsqueda e indagación del pasado reciente a través de dos historias de vida que guardan una profunda conexión con los hechos acontecidos durante el Holocausto. El objetivo es abordar y analizar la construcción (...) de la voz narrativa en cada una de las obras propuestas a partir de su articulación con la figura del silencio. En la obra de Jablonka, se observa, hay una identificación entre el narrador y sus abuelos paternos, mecanismo que se despliega al anular toda inconsistencia o vacío memorial; el silencio dejado por Mates e Idesa es el silencio de su nieto. Por su parte, en el relato de Amigorena, la voz del narrador toma distancia respecto a los acontecimientos al adoptar un punto de vista externo; a la vez que ficcionaliza la historia de su abuelo Vicente y la envuelve de un silencio absoluto e impotente, deja entrever que ese silencio desolador que atraviesa su historia familiar puede ser resignificado desde el presente.

In this article I examine several criticisms of the concept of vulnerability. Rather than rejecting the concept, however, I argue that a sufficiently rich understanding of vulnerability is essential to bioethics. The challenges of international research in developing countries require an understanding of how new vulnerabilities arise from conditions of economic, social and political exclusion. A serious shortcoming of current conceptions of vulnerability in research ethics is the tendency to treat vulnerability as a label fixed on a particular subpopulation. My (...) paper examines the role of this “label” metaphor in current statements of research ethics. In contrast to this prevailing “label” metaphor, my own positive account of vulnerability develops a dynamic way of understanding the structure of the concept of vulnerability based on the idea of “layers of vulnerability.” I examine several cases involving women, as they are sometimes labeled as a vulnerable population and sometimes not. My analysis demonstrates the essential role of this revised concept of vulnerability in bioethics and research ethics. (shrink)

El artículo analiza algunas problemáticas centrales de la literatura caribeña, en particular de expresión francófona y anglófona, relacionadas, por un lado, con la falta de desarrollo y el funcionamiento colonial de sus sistemas literarios, y, por el otro, con el problema social, económico y político de la emigración en las Antillas. Como propongo, es la misma condición migrante de la literatura caribeña, en tanto sistema atravesado por el desplazamiento masivo de sus productores, la que en gran parte determina sus motivaciones (...) e intereses, enfocados a la identidad regional (y a la cultura regionalista) de modo recurrente. El artículo indaga, entre otros lugares-comunes (Glissant) del discurso literario caribeño, su estética geográficamente marcada que es enunciada aun desde un locus migrante (distante) con fines descolonizadores, los cuales se vinculan con la tradición anticolonialista, masculina y de sesgo militante del siglo pasado. Luego de una revisión de este legado a partir de dos aproximaciones críticas (Tinsley, Condé), se lee una serie de textos donde se observa la persistencia de la geoestética antillana, como A Small Place de Jamaica Kincaid, los cuales se apropian creativamente del discurso turístico desde una perspectiva geopolítica de resistencia a las dominaciones aún coloniales.

According to Bronislaw Baczko, utopias may be considered as different forms—they are not linked to any precise literary genre—of critique of social reality and the quest for alternatives. Some consist of a detailed description of a new social order, whereas others confine themselves to an overall design, which solely defines a series of values and principles. They all contain an ideal of perfection: a utopian view of the world always stems from the awareness of a breach between what must be (...) and social reality, which is deemed to be in crisis and dominated by evil. There is, thus, no utopia without an ideal opposed to reality. That said, idealized as they may be, utopias do allow such reality to cease to be deemed.. (shrink)

Se trata de la reseña bibliográfica del libro de Emmanuel Biset et. al., Sujeto, una categoría en disputa.

“Vulnerability” is a key concept for research ethics and public health ethics. This term can be discussed from either a conceptual or a practical perspective. I previously proposed the metaphor of layers to understand how this concept functions from the conceptual perspective in human research. In this paper I will clarify how my analysis includes other definitions of vulnerability. Then, I will take the practical‐ethical perspective, rejecting the usefulness of taxonomies to analyze vulnerabilities. My proposal specifies two steps and provides (...) a procedural guide to help rank layers. I introduce the notion of cascade vulnerability and outline the dispositional nature of layers of vulnerability to underscore the importance of identifying their stimulus condition. In addition, I identify three kinds of obligations and some strategies to implement them. This strategy outlines the normative force of harmful layers of vulnerability. It offers concrete guidance. It contributes substantial content to the practical sphere but it does not simplify or idealize research subjects, research context or public health challenges. (shrink)

Interpersonalist theories of testimony have the theoretical virtue of giving room to the characteristic interpersonal features of testimonial exchange among persons. Nonetheless, it has been argued that they are at a serious disadvantage when it comes to accounting for the way in which testimonial beliefs may be epistemically justified. In this paper, we defend the epistemological credentials of interpersonalism, emphasizing that it is inseparable from the acceptance of non-evidential epistemic reasons to believe, which demands proper conceptual elaborations on the notions (...) of epistemic reasons and of epistemic justification. We offer a proper reading of epistemic reason, and we defend non-purism on justification as the adequate way to conceive the epistemic proposal of interpersonalism on testimony, realizing that only this combination is capable of apprehending certain cases in which there seems to be no way to rule out the idea that the assurance offered by the testifier offers an epistemic reason to believe that it is not evidential.

The goal of this paper is to show how culture – shared norms and values – is challenged and used to facilitate cooperative behavior within the context of farmer field schools (FFS) in central Luzon, Philippines. The success of the FFS is primarily associated with cultural norms that encourage experiential and collective learning and eventually lead to the adoption of integrated pest management (IPM) methods among the farmers. The study was conducted in central Luzon, the rice granary region of the (...) Philippines, from 1992 to 1995 and again in 1999. Both qualitative and quantitative research methods were employed. Results indicate that a keen understanding of Filipino culture and values is essential if FFS is to be successful and if farmers are to successfully learn and practice IPM. (shrink)

In this article I focus on two issues concerning bioethics in Argentina: reproductive health and ethics in research. Although these topics are quite dissimilar, they share a particular feature: their special relationship with context.

In this article, the authors focus on Argentina's activity in the developing field of regenerative medicine, specifically stem cell research. They take as a starting point a recent article by Shawn Harmon (published in this journal) who argues that attempts to regulate the practice in Argentina are morally incoherent. The authors try to show first, that there is no such ‘attempt to legislate’ on stem cell research in Argentina and this is due to a number of reasons that they explain. (...) Second, by examining the role played by different values, conflicting legal and moral views, and the influence of various actors, they attempt to show that the legislative silence regarding stem cell research may not necessarily be a manifestation of a legal/moral disconnection but rather a survival strategy for navigating the long and heated battle on the moral status of the embryo and the kind of treatment it deserves.

The concept of vulnerability is widely used in bioethics, particularly in research ethics and public health ethics. The traditional approach construes vulnerability as inherent in individuals or the groups to which they belong and views vulnerability as requiring special protections. Florencia Luna and other bioethicists continue to challenge traditional ways of conceptualizing and applying the term. Luna began proposing a layered approach to this concept and recently extended this proposal to offer two new concepts to analyze the concept of (...) vulnerability, namely understanding external conditions that trigger vulnerability and layers of vulnerability with cascading effects. Luna's conception of vulnerability is useful, which we demonstrate by applying her layered view and the new analyses in multiple contexts. We begin by outlining Luna's view and we use vignettes from healthcare involving transgender patients, the care of patients in psychiatric contexts, and research involving prisoners to illustrate how each part of Luna's concept elucidates important moral issues.

This paper challenges the traditional account of vulnerability in healthcare which conceptualizes vulnerability as a list of identifiable subpopulations. This list of ‘usual suspects’, focusing on groups from lower resource settings, is a narrow account of vulnerability. In this article we argue that in certain circumstances middle-class individuals can be also rendered vulnerable. We propose a relational and layered account of vulnerability and explore this concept using the case study of cord blood (CB) banking. In the first section, two different (...) approaches to ‘vulnerability’ are contrasted: categorical versus layered. In the second section, we describe CB banking and present a case study of CB banking in Argentina. We examine the types of pressure that middle-class pregnant women feel when considering CB collection and storage. In section three, we use the CB banking case study to critique the categorical approach to vulnerability: this model is unable to account for the ways in which these women are vulnerable. A layered account of vulnerability identifies several ways in which middle-class women are vulnerable. Finally, by utilizing the layered approach, this paper suggests how public health policies could be designed to overcome vulnerabilities. (shrink)

El debate en torno a Aristipo de Cirene, cuya concepción de la felicidad coloca en el centro de la escena al placer, pone en tela de juicio las afirmaciones propias de aquellas éticas nucleadas bajo el epíteto de eudemonistas. Con el desplazamiento de la felicidad del sitial del fin, Aristipo reformula la dimensión ética tradicional: a través del ejercicio de la enkráteia, y lejos de caer en un relativismo subjetivista, intenta construir una ética que tenga como base un objetivismo gnoseológico. (...) Demostraremos, además, que al ejercicio de la enkráteia cirenaica subyace la noción de autosuficiencia (autárkeia) -entendida en términos aristotélicos- del individuo. Esto nos enfrentará, irremediablemente, a la noción aristotélica de felicidad (en estrecho vínculo con la noción de enkráteia), la cual no comporta una noción de autosuficiencia individual sino que restringe la posibilidad de la autárkeia a la autosuficiencia de la pólis. The debates on Aristippus of Cyrene, whose happiness' conception puts pleasure in the center of the scene, questions the claims of those ethical nucleated under the epithet "eudemonists". Through the shift of happiness from the shrine of the goal, Aristippus reformulates the traditional ethical dimension: by the enkráteia's exercising -and far from falling into a subjective relativism- he tries to build an ethic based on an epistemological objectivity. We are going to demonstrate also that the self-sufficiency concept (autárkeia) -speaking in Aristotelian terms- of individual underlies the exercise of Cyrenaic enkráteia. It will face us inevitably to the Aristotelian concept of happiness (in close connection with the enkráteia's concept), which doesn't involve a notion of individual self-sufficiency, but rather it restricts the possibility of autárkeia to the pólis' self-sufficiency.

Traditional accounts of vulnerability tend to label entire populations as vulnerable. This approach is of limited utility. Instead, this article utilizes a layered approach to vulnerability, identifying multiple vulnerabilities that older people experience. It focuses on distinguishing the different layers of vulnerability that may be experienced by the elderly in middle-income countries of Latin America. In doing so, I show how the layered approach to vulnerability functions, and demonstrate why it is more interesting and useful than the traditional approach. The (...) article achieves three things. First, it unwraps the different potential layers of vulnerability that develop in old age and the multidimensionality aspects of aging. Second, it reestablishes the usefulness of the concept of vulnerability and explains its functioning. Finally, it shows how different policies can be designed in order to address each vulnerability layer. The layered account promotes a multifaceted approach to public policy analyses and design. In this sense, the layered concept of vulnerability is an appealing concept to consider in public health ethics. (shrink)

Non-communicable diseases are no longer largely limited to high-income countries and the elderly. The burden of non-communicable diseases is rising across all country income categories, in part because these diseases have been relatively overlooked on the global health agenda. Historically, communicable diseases have been prioritized in many countries as they were perceived to constitute the greatest disease burden, especially among vulnerable and poor populations, and strategies for prevention and treatment, which had been successful in high-income settings, were considered feasible and (...) often affordable in low-income settings. This prioritization has reduced the communicable diseases burden globally but has left non-communicable diseases largely neglected. A new approach is urgently needed to tackle non-communicable diseases. Based on an analysis of potential features which may have underlain the different approaches to non-communicable diseases and communicable diseases until now, including acuity of disease, potential for control or cure, cost, infectiousness, blaming of individuals and logistical barriers, little ethical or rational justification can be found to support continued neglect of non-communicable diseases. Justice demands access to quality and affordable care for all. An equitable approach to non-communicable diseases is therefore strongly mandated on medical, ethical, economic, and public health grounds. Funding must not however be diverted away from communicable diseases, which continue to require attention—but concomitantly, funding for non-communicable diseases must be increased. International and multi-sectoral action is required to accelerate progress towards true universal health coverage and towards achievement of all of the sustainable development goals, such that prevention and access to care for non-communicable disease can become a global reality.
