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)

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.

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.

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

Durante las últimas décadas del siglo XIX y las primeras del siglo XX, el paradigma higienista se constituyó en una de las principales influencias para determinar políticas en pos de la construcción de un proyecto de país y de una ciudadanía homogénea desde el parámetro de la civilización. El objetivo de este artículo será indagar la forma en la que el higienismo como política, paradigma y disciplina se instaló como el conocimiento autorizado para mejorar las condiciones de salud de la (...) población, dentro de los Territorios Nacionales de la Patagonia, en particular en escuelas ubicadas dentro de territorios mapuche entre 1900 y 1940. Para realizar este análisis, serán retomadas las crónicas de dos maestros, Luis Funes y Luis Feldman Josín, que fueron destinados a parajes con población indígena en la región patagónica. Por otra parte, analizaremos los efectos de la interacción de estos discursos con otros disponibles en la mitad del siglo XX a partir de los cuales se interpelaba a los sujetos indígenas, como, por ejemplo, aquellos que postulaban la dicotomía entre "civilización - barbarie”. Y, finalmente, caracterizamos los contrapuntos entre el establecimiento de las normativas a nivel nacional y la particularidad de su gestión en la Patagonia. (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.

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 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 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)

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.

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)

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)

In this paper I state that throughout Walter Benjamin’s writings a constant element can be found: the aim to ground knowledge on demand of redemption of the object. I show that in the four realms where the Benjaminian theory of knowledge is developed –philosophy, art criticism, translation and historical knowledge–, the principal categories of his conception stress this demand by a peculiar use of the suffix “barkeit”, present in the concepts of “solutionabiliy” of the philosophical task, the “criticizability” of the (...) artwork, the “translatability” of language and the “now of cognizability” of the past.

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)

“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)

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)

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.

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)

This article examines the problems that research ethics confronts in developing countries and the impact that research in developing countries has had on research ethics. In order to show this it analyzes the first paradigmatic cases that gave rise to the ‘classic’ analysis of research ethics.

Secondly, the article describes the complex process of research by analyzing different research actors (...) and their interests in the current research process. Thirdly, it sketches some of the recent cases that have prompted fierce ethical debate surrounding research in developing countries. (shrink)

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)

En este trabajo se investigan cuáles fueron las razones de Benjamin para proyectar su tesis doctoral sobre el concepto de "tarea infinita" en la filosofía de la historia de Kant, así como los motivos por los que abandonó ese plan. Se destaca la influencia decisiva de Hermann Cohen en este intento, así como las diferencias entre sus concepciones del mesianismo, y se muestra que en los esbozos de aquel proyecto doctoral frustrado se encuentra en germen la aspiración benjaminiana de fundamentar (...) el conocimiento en una concepción mesiánica de la historia. Además, se sostiene que, con este fin, Benjamin reelaboró la noción de "tarea infinita" en relación con una exigencia de redención que fundamenta la esfera cognoscitiva. In this paper we investigate the reasons which led Benjamin to project his doctoral dissertation on the concept of "infinite task" in Kant's philosophy of history, as well as the motives behind his subsequent abandonment of that project. We stress both the crucial influence of Hermann Cohen behind Benjamin's expectations and the differences between their conceptions of messianism. Our aim is to show that the outlines remaining from Benjamin's frustrated doctoral project contain the seeds of his lasting aspiration to lay the foundation of knowledge in a messianic conception of history. With this intention, we maintain, Benjamin interprets the notion on "infinite task" in connection with a demand of redemption that grounds the cognitive sphere. (shrink)
