Here we study polysemy as a potential learning bias in vocabulary learning in children. Words of low polysemy could be preferred as they reduce the disambiguation effort for the listener. However, such preference could be a side-effect of another bias: the preference of children for nouns in combination with the lower polysemy of nouns with respect to other part-of-speech categories. Our results show that mean polysemy in children increases over time in two phases, i.e. a fast growth till the 31st (...) month followed by a slower tendency towards adult speech. In contrast, this evolution is not found in adults interacting with children. This suggests that children have a preference for non-polysemous words in their early stages of vocabulary acquisition. Interestingly, the evolutionary pattern described above weakens when controlling for syntactic category (noun, verb, adjective or adverb) but it does not disappear completely, suggesting that it could result from a combination of a standalone bias for low polysemy and a preference for nouns.

Chemical embryology was born in 1931 with the publication of Chemical Embryology by Joseph Needham. In the following two decades it became an innovative research project aiming at the description of the construction of the embryological structure and differentiation in biochemical terms. This research programme produced a vast amount of experimental evidence and theories on the chemical dynamics of the embryo: particularly chemical characterization of the zygote and the developing embryo, the chemical exchanges between the nucleus and the cytoplasm, the (...) significance of subcellular structures, and the role and distribution of nucleic acids within the cell. From the 1950s on, a large part of these results came to be integrated into the empirical basis of molecular biology. However, the shift from chemical embryology to molecular embryology was not just a semantic shift but a deep theoretical change, produced by the introduction of a new model of scientific explanation, based on the transmission and expression of genetic information and opposed to the biochemical definition of life.

Cet ouvrage s'inscrit dans le fil du travail collectif entrepris en 1995, l'Histoire de la pensée médicale en Occident (trois volumes sous la direction de Mirko D Grmek, Seuil, 1995, 1997, 1999). Il rend compte du déploiement des recherches pluridisciplinaires et transdisciplinaires de la pensée médicale et aborde les discussions et controverses actuelles sur les politiques de santé. Du fait du développement des connaissances théoriques et des innovations techniques, la notion même de soin, sous ses aspects sociaux, économiques, mais aussi (...) épistémiques, se trouve questionnée. La pensée médicale ne saurait se limiter aux données biologiques, et ses composantes spécifiquement humaines et sociales sont explorées et interrogées ici dans une perspective historique qui tient compte des découvertes du dernier siècle.

In this paper, the sociopolitical status of nurses in the Philippines is examined. The importance of nursing research in identifying the many elements that contribute to inequality among nurses is critical in the face of these problems. The positivist and interpretivist perspectives, however, have limitations that could potentially perpetuate the many forms of inequality that already exist. The idea of political competency is introduced in this tension. A critical grasp of the elements that contribute to structural inequalities and a commitment (...) to bringing about positive social changes make political competency a potential supplement to the limitations of critical theory.

From its first proposal, the Central Dogma had a graphical form, complete with arrows of different types, and this form quickly became its standard presentation. In different scientific contexts, arrows have different meanings and in this particular case the arrows indicated the flow of information among different macromolecules. A deeper analysis illustrates that the arrows also imply a causal statement, directly connected to the causal role of genetic information. The author suggests a distinction between two different kinds of causal links, (...) defined as 'physical causality' and 'biological determination', both implied in the production of biological specificity.

For decision making in government, it is necessary to have well-structured sources of information. In several countries, it is difficult to access government data as the information are dispersed, disconnected, and poorly structured. For this reason, this work presents a framework to gather, unify, and enrich missing person data from distributed web sources. The framework allows inserting new tasks specific to the user’s domain to improve data quality. In this study, Brazilian missing person data from non-governmental organizations (NGOs) and governmental (...) websites were collected and semantically enriched. To enhance the understanding of the gathered missing people cases, we create interpretive models using machine learning techniques to extract knowledge and to encourage the use of standards for publishing the data that are frequently ignored by organizations, hindering analysis and decision-making on data. After the collection and semantic enrichment process, there was an increase of approximately 11% in the data present in the base. Also, the mining process evidenced the disappearance and reappearance of a person in Brazil according to several factors such as age, state initiatives, skin tone, hair colors, etc. (shrink)

En el presente artículo nos hemos propuesto analizar las variantes textuales griegas relativas a los términos “vino” y “vinagre” dentro del contexto neotestamentario de la Pasión de Cristo, así como sus correlatos en la traducción de los Evangelios en antiguo eslavo. Como resultado de dicho análisis, hemos detectado una tendencia a introducir el término “vinagre” por parte de la tradición textológica del Nuevo Testamento griego, que es secundada además por otras tradiciones, como la siríaca o la eslava.

This essay examines Arendt's descriptions of "Hottentots" in The Origins of Totalitarianism, especially the comparisons and contrasts she frequently draws between Hottentots and other peoples. In particular, Arendt highlights dehumanization of presumptively "civilized" people in comparing them to Africa "savages." Close reading of such analogies demands that we look beyond the racial explanations that other scholars have offered and focus instead on how Arendt's conception of humanity is bound up with a specific sense of culture that is antiprimitivist—exclusive of peoples (...) without history, primitives. Analysis of her moral anthropology uncovers the Cape Colony discourses and postenlightenment German philosophical supports that inform her antiprimitivism. However, Arendt's antiprimitivism may not remain confined to Origins. In later essays,Arendt analyzes the various aspects of culture in instructive ways. Yet she also synthesizes culture concepts into a schema that introduces problems for her. (shrink)

Childhood has been historically and socially linked to the idea of lack, absence, or incompleteness. This understanding has led to the consequent idea that the adult universe could fill it--complete it with what it is supposedly missing. Historically speaking, the adult exercise of power over children has become generalized and has acquired a strong ally in the educative process. We presume to know so much about children, and we interpret them from the point of view of what we ourselves have (...) been, or from what we imagine we have been been. Our individual experiences are perceived as models for the infant understanding of things. Paradoxically enough, our knowledge about childhood separates us from it. We already know a lot about childhood, we think; there’s nothing more to say. But maybe that’s preferable, for if there is nothing more to say about childhood, the time to learn with children what childhood has to say to us has come. To think childhood only in the space allowed within the margins of our interpretative schemes is to mistrust the possibility that children can or have ever escaped those imposed dimensions. But, what about thinking childhood on or outside those margins? To talk about the childhood invented by the Brazilian poet Manoel de Barros, by his memories and ours, and to search for new concepts of childhood, demands a different approach. Childhood as we have come to understand here makes of teaching--as of reading and writing in general--a poetic experience, full of feelings, emotion and reason. What is proposed here as a project of inquiry is in this case the same as many others, but also profoundly different, and difficult to inaugurate, for here the object—childhood--is altered by the gaze of the inquirer herself, which implicitly changes the character and even the details of the methodology which follow from the gaze.

This article analyses the original core of the ‘Art’ of Ramon Llull, which, according to the author, was the result of a vision on Mount Randa. We start from the paradoxical fact that Llull describes his Art as a result of an immediate revelation, but throughout his life constantly reworked the artistic structure, in both formal and procedural aspects. We thus take a hermeneutical approach to the ontology, logic and symbolism of Llull’s Art to define as precisely as possible what (...) remained constant through the changes. We conclude that the so-called ‘illumination of Randa’ was actually a mystical vision of the cosmos and its internal relations, but not the argumentative process of the Art, which Llull clarified over the course of his life.

Imagination has received a great deal of attention in different fields such as psychology, philosophy and the cognitive sciences, in which some works provide a detailed account of the mechanisms involved in the creation and elaboration of imaginary worlds. Although imagination has also been formalized using different logical systems, none of them captures those dynamic mechanisms. In this work, we take inspiration from the Common Frame for Imagination Acts, that identifies the different processes involved in the creation of imaginary worlds, (...) and we use it to define a dynamic formal system called the Logic of Imagination Acts. We build our logic by using a possible-worlds semantics, together with a new set of static and dynamic modal operators. The role of the new dynamic operators is to call different algorithms that encode how the formal model is expanded in order to capture the different mechanisms involved in the creation and development of imaginary worlds. We provide the definitions of the language, the semantics and the algorithms, together with an example that shows how the model is expanded. By the end, we discuss some interesting features of our system, and we point out to possible lines of future work. (shrink)

Anton Dohrn projected the Stazione Zoologica as composed of two complementary halves: nature and culture. This attitude was not only expression of the general cultural background of the nineteenth century cultural elite, for Dohrn both formed a coherent and organized whole. In my essay I will analyse the different levels of the relationship between music and biology. In particular, I will demonstrate that both share similar “styles of thought”. In the last part I will show that Dohrn’s most important scientific (...) contribution, the concept or “principle” of Functionswechsel, provides evidence for the link he had established between music and biology -/- .
