In this article, we propose the Fair Priority Model for COVID-19 vaccine distribution, and emphasize three fundamental values we believe should be considered when distributing a COVID-19 vaccine among countries: Benefiting people and limiting harm, prioritizing the disadvantaged, and equal moral concern for all individuals. The Priority Model addresses these values by focusing on mitigating three types of harms caused by COVID-19: death and permanent organ damage, indirect health consequences, such as health care system strain and stress, as well as (...) economic destruction. It proposes proceeding in three phases: the first addresses premature death, the second long-term health issues and economic harms, and the third aims to contain viral transmission fully and restore pre-pandemic activity. -/- To those who may deem an ethical framework irrelevant because of the belief that many countries will pursue "vaccine nationalism," we argue such a framework still has broad relevance. Reasonable national partiality would permit countries to focus on vaccine distribution within their borders up until the rate of transmission is below 1, at which point there would not be sufficient vaccine-preventable harm to justify retaining a vaccine. When a government reaches the limit of national partiality, it should release vaccines for other countries. -/- We also argue against two other recent proposals. Distributing a vaccine proportional to a country's population mistakenly assumes that equality requires treating differently situated countries identically. Prioritizing countries according to the number of front-line health care workers, the proportion of the population over 65, and the number of people with comorbidities within each country may exacerbate disadvantage and end up giving the vaccine in large part to wealthy nations.

Learning about a scientific concept often occurs in the context of unfamiliar examples. Mutual alignment analogy ? a type of analogical comparison in which the analogues are only partially understood ? has been shown to facilitate learning from unfamiliar examples . In the present study, we examined the role of mutual alignment analogy in the abstraction and transfer of a complex scientific concept from examples presented in expository texts. Our results provide evidence that (a) promoting comparison between two examples and (...) (b) orienting the learner toward relational commonalities result in greater abstraction and transfer. These findings suggest that mutual alignment analogy is an effective means of promoting abstraction and transfer of complex scientific concepts, and may thus be used in the classroom to promote learning from unfamiliar examples.

Understanding the day/night cycle requires integrating observations of the sky (an Earth-based perspective) with scientific models of the solar system (a space-based perspective). Yet children often fail to make the right connections and resort to non-scientific intuitions – for example, the Sun moving up and down – to explain what they observe. The present research explored whether children’s gestures indicate their conceptual integration of Earth- and space-based perspectives. We coded the spontaneous gestures of 85 third-grade children in U.S. public schools (...) (Mage = 8.87 years) as they verbally explained the overall cause of the day/night cycle, the cause of sunrise, and the cause of sunset after receiving science instruction as part of a prior study. We focused on two kinds of gestures: those reflecting the Sun’s motion across the sky and those reflecting the Earth’s axial rotation. We found that participants were more likely to produce Earth rotation gestures for a topic they explained more accurately (the overall cause of the day/night cycle), whereas Sun motion gestures were more common for topics they explained less accurately (the causes of sunrise and sunset). Further, participants who produced rotation gestures tended to provide more accurate verbal explanations of the overall cause. We discuss how gestures could be used to measure – and possibly improve – children’s conceptual understanding and why sunrise and sunset may be particularly difficult topics to learn. (shrink)

Revisión del libro ESMA. Represión y poder en el centro clandestino de detención más emblemático de la última dictadura argentina por M. Franco y C. Feld.

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)

The concept of vulnerability has been hotly debated in research ethics literature. Some critics considered it a useless concept. In 2009—against some of those criticisms—I defended the importance of understanding this concept in terms of layers instead of applying it as a label given to certain subpopulations. In this paper, I present some of the limits of this analysis and I also explore the similarities and differences this approach has when compared to using a taxonomy as another answer on how (...) to assess vulnerability. I present the notion of cascade vulnerability and underscore the dispositional character of layers and their relevance to identify and evaluate layers of vulnerability. Finally, I show how this layered account has been incorporated in important documents such as the new 2016 CIOMS-WHO Guidelines. (shrink)

This essay examines the construction of a symbolic figure who has worked to support the reordering of power relationships. It is the invention of a foreign enemy, Islamic radicalism from which United States has served its objectives of establishing a new hegemony. Since the terrorist threat, has extended a speech level that adulterated and showed us a world divided into two opposite poles: a virtuous and civilized axis that is forced to attack to defend itself, and a barbaric and evil (...) axis that threatens global security. But this process is fraudulent, that has been able to violate international law, has a political, historical and economic issues should be unmasked. (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.

Throughout this essay, I will consider an argument frequently used to justify paternalistic behavior toward a specific class of persons: illiterate people. The argument states that illiterate people are uneducated, lack information and understanding, and are thus unable to make decisions. Therefore, it is argued, paternalism in their case is justified. The conclusion is that illiterate persons cannot be autonomous. The justification for this view is based on an a priori attitude: since it is impossible to communicate, physicians should decide (...) which kind of treatment the illiterate patient should receive. This argument is frequently used even though its proponents may not be aware of its implications. Given the importance and uncritical acceptance this argument has in Argentina, and also in other Latin American countries, I think it is relevant to analyze carefully what it means. I propose a thorough analysis of this argument, of its implications and an evaluation of whether it is acceptable. (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.

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)

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 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.

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)

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.

“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)

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.

En el presente trabajo abordamos dos caracterizaciones diferentes del pasado en la obra tardía de Walter Benjamin: una concibe el pasado como “inconcluso” o “trunco”; la segunda lo describe como “originario” o “primitivo”. Analizamos ambas caracterizaciones, proponemos una posible complemetariedad entre ambas, y sostenemos que esta doble concepción del pasado permea en su totalidad su idea de redención, en contraste con la función del pasado y de la redención en otros pensadores del marxismo occidental (Adorno, Horkheimer).

The article examines the meaning of the concepts of "doctrine" and "tradition" in Walter Benjamin's 1917 reflections, concepts that are closely linked to his reception of Kant. Given the scarce analysis of this appropriation, the paper seeks to show that these concepts express an interest in Kant's idea of the systematic unity of knowledge and that Benjamin reinterprets such unity in Messianic terms, that is, not as a necessary assumption, but as a demand for redemption. Finally, it shows how these (...) notions are implicit in Benjamin's On the Program of the Coming Philosophy. (shrink)

The specialist literature has investigated extensively the link between Benjamin and German Romanticism and, less frequently, his relation to Kant. However, these contributions tend to take up these links separately, and therefore do not analyse in detail the process which begins with the theoretical sketches on Kant and concludes with the writing of the doctoral thesis on the Frühromantik. This paper argues that there is a marked continuity between the objectives which led Benjamin to plan, in the first place, his (...) doctoral investigation on Kant and those which were finally realized. I try to demonstrate that such continuity consists in a displacement of the problem of the justification of knowledge, from the field of the criticism of knowledge in general to a particular sphere: that of art criticism. In this shift the purpose of linking the justification of knowledge with a messianic philosophy of time and history is also preserved. (shrink)
