The reclamation of the body in cognitive psychology and philosophy of mind has been united with that of intersubjectivity in the so-called second-person perspective. The ontogenetic precedence of this view does not, however, entail disaffirmation of the competing theories, which is why it is necessary to clarify how the three can coexist in explaining different cases of mental attribution. Along with this, it has become a matter of debate whether the understanding of the facial expression of the other is in (...) origine by direct perception or corresponds to a semiotic process. The text addresses both questions and makes a case for a primitive, non-semiotic perception of emotion in the face and body of other people. The text addresses both questions and makes a case for a primitive, non-semiotic perception of emotion in the face and body of other people, which would later be the object of a semiotization when the -originally inseparable- expression-emotion complex splits into parts as a result of the interruption of direct affective-bodily contact in adult-baby interactions.

ABSTRACTIn two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes (...) can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality. (shrink)

DNA methylation constitutes one of the pillars of epigenetics, relying on covalent bonds for addition and/or removal of chemically distinct marks within the major groove of the double helix. DNA methyltransferases, enzymes which introduce methyl marks, initially evolved in prokaryotes as components of restriction‐modification systems protecting host genomes from bacteriophages and other invading foreign DNA. In early eukaryotic evolution, DNA methyltransferases were horizontally transferred from bacteria into eukaryotes several times and independently co‐opted into epigenetic regulatory systems, primarily via establishing connections (...) with the chromatin environment. While C5‐methylcytosine is the cornerstone of plant and animal epigenetics and has been investigated in much detail, the epigenetic role of other methylated bases is less clear. The recent addition of N4‐methylcytosine of bacterial origin as a metazoan DNA modification highlights the prerequisites for foreign gene co‐option into the host regulatory networks, and challenges the existing paradigms concerning the origin and evolution of eukaryotic regulatory systems.

Resumen. En la presente investigación se describe el análisis de sentimiento realizado en comentarios publicados en la red social de Twitter. Los datos se obtuvieron al monitorear durante 36 días la evaluación del sentimiento de los comentarios que resultaron de hacer búsquedas de catorce diferentes sistemas operativos para celular; utilizando para dicha evaluación la herramienta Twitter-Sentiment. Se encontró que los comentarios positivos y negati¬vos presentan una correlación positiva para la mayoría de los sistemas operativos utilizados en la investigación.. The present (...) research describes the sentiment analysis carried on com¬ments published on the social network Twitter. The data were obtained by monitoring over 36 days of evaluation on the sentiment of the comments that resulted from querying four¬teen different mobile operating systems; using Twitter-Sentiment for the evaluation. It was found that the positive and negative comments have a positive correlation for most operating systems used in this research. (shrink)

En este trabajo estudiamos varios modelos de tratamiento del sentido de agencia, entendido como aspecto fenoménico que acompaña a las acciones e indica la pertenencia de la acción al sujeto. Proponemos que el sentido de agencia no sea considerado como un criterio suficiente de agencia, o acción intencional, a menos que se integre en un conjunto más fuerte y abstracto de requisitos que contienen una dimensión epistemológica: asegurar la determinación de la acción por la intención. We discuss the conditions that (...) the knowledge of an action must meet to reach the status of agency or complete intentional action. A first problem is to account how the subject appears in the action. We consider the model of a "sense of agency" and we oppose a theory of action control that does not take in charge the epistemological problems associated to the sense of agency model. Our claim is that epistemological requirements are intrinsic components of the agency, and therefore that a theory of action must take in account an epistemological perspective in some nuclear aspects of the production of actions.

En este artículo pretendemos arrojar luz sobre la normatividad propia del conocimiento humano. Describimos el dominio normativo epistémico como un campo de agencia humana que está definido por el conocimiento entendido como logro. La normatividad del conocimiento se apoya en la contribución del agente epistémico a la consecución de ciertas tareas. Tal contribución es epistémicamente significativa cuando el agente llega a participar en la consecución del éxito. Por último identificamos algunos rasgos asociados con la agencia epistémica completa (condiciones de integración (...) cognitiva y autonomía epistémica), y aclaramos lo que queremos decir con implicación apelando a la idea de adoptar una perspectiva epistémica.

El propósito de este ensayo es mostrar los logros iniciales, pero decisivos, que Sartre gana para la futura constitución de su ontología fenomenológica. Además se señalan los vacíos –básicamente la abstracción de la libertad, su separación radical del Ego– que lo imposibilitan para establecer criterios valorativos de decisión y dar cuenta de la continuidad de la personalidad. Palabras clave : Sartre; conciencia pre-reflexiva; ego; libertad. Libertarianism of the Ego’s TranscendenceThe purpose of this essay is to show the initial, yet decisive (...) achievements that Sartre attains for the future constitution of his phenomenological ontology. Besides, I point to the gaps –basically the abstraction of freedom, its radical separation from the Ego– which make it impossible for him both to establish valuation criteria on decisions and explain the continuity of personality. Keywords : Sartre; Pre-Reflective Consciousness; Ego;Freedom. (shrink)

Se revisan varios libros publicados recientemente que corresponderían al campo de la epistemología política. Sus autores pertenecen a tradiciones tan distintas como los Estudios sobre la Ciencia, Sociologíael Conocimiento, Epistemología, Filosofía de la Ciencia o Economía. La convergencia en este tema es el dato más significativo, habida cuenta de las bien conocidas controversias contemporáneas sobre la ciencia.El núcleo central de los trabajos es la relación entre ciencia y democracia.

En este trabajo nos proponemos defender una versión de la tesis de la �mente extendida� frente a las críticas de algunos autores para quienes los sistemas que llaman �extracraneales� no cumplirían las condiciones que deben cumplir los componentes de los procesos mentales. Proponemos la integración de funciones como un criterio para considerar un conjunto de procesos como un proceso mental. Desde este punto de vista, consideramos que, en ciertas situaciones, algunos sistemas externos podrían llegar a cumplir este criterio.

The dorsal and medial pallial formations of mammals, birds, and reptiles show overall functional striking similarities. Most of these similarities have been frequently considered examples of convergent evolution. However, a considerable amount of neurobiological comparative evidence suggests the presence of a common basic pattern of vertebrate forebrain organization. This common pattern can support functional conservation.
