Las fake news se suelen caracterizar como contenidos, de modo que prevalece el planteamiento semántico. Aquí se propone un enfoque pragmático, donde son actos comunicativos intencionales. Esto permite entender las fake news desde los actos locucionarios, ilocucionarios y perlocucionarios. Esta triple versión de intencionalidad comunicativa permite una mejor intelección de la mala información (misinformation) y de la desinformación (disinformation), que se refleja con claridad en el caso económico.Para mitigar o neutralizar los daños causados por las fake news en el tejido (...) social, se suele recomendar la contrastación de hechos (fact checking). La contribución de la Economía Experimental —y, en concreto, la aportación de Alvin Roth (Premio Nobel de Economía 2012)— puede ser especialmente relevante en dos direcciones: (a) la actividad económica y (b) la Economía como actividad entrelazada con otras. Esto supone el contrastar hechos partiendo de la intencionalidad en la actividad económica, en cuanto tal y en su nexo con otras actividades humanas. A este respecto, las fake news convergen con la toma de decisiones económicas, en cuanto que ambas están surcadas por la intencionalidad y, además, tienen lugar en un contexto donde adquieren un perfil orientado a fines.

La investigación científica trae consigo múltiples cuestiones, que este libro analiza centrándose en dos grandes corrientes metodológicas: el pragmatismo y el pluralismo. En el primero destacan autores como Nicholas Rescher, que tiene un capítulo en el libro, y en lo segundo hay cada vez más partidarios, muchos de los cuales reconocen el papel de Patrick Suppes en el giro para deslindarse del monismo metodológico, que fue dominante durante un buen número de años. Mediante la reflexión filosófico-metodológica se profundiza en el (...) libro en los procedimientos de investigación, que es la fase inicial para resolver problemas científicos, y en los métodos, que siguen después, dotados mayor grado de rigor que propician la sistematicidad en la indagación de lo real (sea natural, social o artificial). Por un lado, quien investiga ha de seguir los procesos para estudiar adecuadamente su objeto y poder resolver los problemas que plantea ese estudio; y, por otro lado, la realidad a conocer ha de ser inteligible mediante los recursos epistemológicos, de uso de procesos de investigación y de los materiales adecuados, bien sea para la observación o para la investigación.

El tema de esta investigación se refiere a la participación de los catedráticos rioplatenses de Derecho en la construcción de los criterios públicos de justicia. Tiene que ver, por lo tanto, con contenidos teóricos vinculados a la teoría de la Justicia y a la teoría del Derecho y del Estado, y con una situación histórica en que el debate de los juristas se orienta hacia un proyecto de reforma social. Estos contenidos, particulares e irrepetibles por ser históricos y característicos de (...) ciertas coyunturas del proceso temporal, son el resultado de una particular sensibilidad pública en que se mezclan las ideologías, con su pureza doctrinaria, con los prejuicios, con las condiciones necesarias para el equilibrio institucional, con el problema social, con la diversidad cultural de los inmigrantes y con las opuestas tendencias hacia la integración y la exclusión al ofrecer y negar la democracia. El universo de estudios específico es lo que denominamos comunidad rioplatense de juristas, comprendiendo a los catedráticos de Montevideo, Buenos Aires, La Plata y Córdoba, ya que de las fuentes relevadas surgen pruebas de la existencia de una comunidad intelectual y de su protagonismo en el debate ideológico de hace un siglo. Estos doctores aportaron una carga simbólica a la comunicación de ideas, pues su papel asignado socialmente y en gran medida auto atribuido es el de crear y difundir conocimientos, el de tener la última palabra sobre un asunto en discusión, para lo que pueden recurrir a fuentes que sólo están a su alcance. Su papel social es imprescindible. Forjan ideología al mismo tiempo que plasman y critican el orden social. (shrink)

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

La economía en Leonardo Polo se ocupa de estudiar el accionar de las personas humanas. Su visión corrige el reduccionismo de quienes limitan el saber económico al análisis de precios, mercados y determinación de rentas individuales y excluyen el estudio de los fines humanos. Para el efecto se sirve de su antropología trascendental, distinguiendo en el hombre naturaleza, esencia y ser personal; sin limitarse a traslapar sino investigando mediante los métodos distintivos del saber estrictamente económico. Sostiene que sólo una organización (...) que integre aquellas tres dimensiones permite un verdadero ex-sistir humano. La empresa reúne tal condición. (shrink)

International research enrolling human subjects has raised an ethical concern regarding the just distribution of benefits between the countries that design the research and the host communities. Although several universal declarations have expressed this concern, a gap between theory and practice continues to exist, as well as a significant divergence between the design of the research protocol and the social context where it will be implemented. Although institutional review boards have made a valuable effort to evaluate international research, their sensitivity (...) to the just sharing of research benefits as well as their attention to the social context must be evaluated.

Este texto analiza el modelo de masculinidad transferido por las narrativas icónicas de los libros de texto de Ciencias Sociales de 5º de E. Primaria. Partiendo de la coeducación como herramienta transformadora de los patrones masculinos hegemónicos tradicionales asociados a la agresividad, la competitividad y la violencia, se abordan los estudios de género sobre la historia escolar, a fin de realizar un diagnóstico sobre la situación actual en torno a las investigaciones de las masculinidades en la Didáctica de las Ciencias (...) Sociales. Se ha creado una ficha multivariable, fácil y sencilla, a fin de que pueda ser aplicada por el propio alumnado de Primaria en sus propios libros de texto, los cuales pasan de ser instrumentos transcriptores de relatos históricos construidos, a ser herramientas de discusión y reflexión crítica sobre género en el pasado y el presente.

School psychologists often break confidentiality if confronted with risky adolescent behavior. Members of the National Association of School Psychologists ( N = 78) responded to a survey containing a vignette describing an adolescent engaging in risky behaviors and rated the degree to which it is ethical to break confidentiality for behaviors of varying frequency, intensity, and duration. Respondents generally found it ethical to break confidentiality when risky adolescent behaviors became more dangerous or potentially harmful, although there was considerable variability between (...) respondents. Significant gender effects were found between male and female respondents for alcohol use, and a significant Form Type (i.e., male or female vignette) Frequency/Duration interaction was observed for antisocial behaviors. School psychologists could benefit from further training in ethical decision making because these ethical dilemmas are not always clear-cut. (shrink)

Ample attention is being paid in the higher education literature to promoting active learning among students. However, critical examination of educational purposes and ends is largely lacki...

The purpose of professional education programs is to prepare aspiring professionals for the challenges of practice within a particular profession. These programs typically seek to ensure the acquisition of necessary knowledge and skills, as well as providing opportunities for their application. While not denying the importance of knowledge and skills, this paper reconfigures professional education as a process of becoming. Learning to become a professional involves not only what we know and can do, but also who we are (becoming). It (...) involves integration of knowing, acting, and being in the form of professional ways of being that unfold over time. When a professional education program focuses on the acquisition and application of knowledge and skills, it falls short of facilitating their integration into professional ways of being. In addition, through such a focus on epistemology (or theory of knowing), ontology (or theory of being) is overlooked. This paper explores what it means to develop professional ways of being where the focus is becoming, not simply knowing as an end in itself. (shrink)

In higher education, the conventional design of educational programs emphasises imparting knowledge and skills, in line with traditional Western epistemology. This emphasis is particularly evident in the design and implementation of many undergraduate programs in which bodies of knowledge and skills are decontextualised from the practices to which they belong. In contrast, the notion of knowledge as foundational and absolute has been extensively challenged. A transformation and pluralisation has occurred: knowledge has come to be seen as situated and localized into (...) various 'knowledges', and the status of the body has taken on renewed significance in epistemological debates. Rather than thinking of knowledge as transcending the body, the embodiment of knowledge has become a key factor in understanding the nature of knowledge and what it means to know. In this paper, we adopt a phenomenological perspective in exploring the notion of embodied knowing as it relates to higher education programs and, more specifically, the ways in which information and communication technologies (ICTs) are used in these programs.

During the last decades the question of defining life has gained increased interest but, at the same time, the difficulty in reaching consensus on a possible answer has led many to skeptical positions. This, in turn, has raised a wider debate about why defining life is so hard and controversial. Such a debate introduces additional aspects to be considered, like the role and nature of a definition of life itself. In this paper, we will focus on those aspects, arguing that (...) progress can be made if we conceive definitions of life as open heuristic tools that contribute to develop specific research strategies in the biological sciences and, more generally, to increase our understanding of life’s complexity. In contrast with pragmatic or operationalist approaches, we will defend that definitions of life comprise a set of ontological assumptions, together with an inherent unifying vocation, so they should be subject to comparison and critical assessment, closely related to the success or failure of the corresponding research programs, but also to the success or failure in establishing well-grounded interconnections among the latter. We consider that the search for a more coherent, integrated and generalized theory of biology cannot be pursued without keeping an empirical standpoint, and the exercise of defining life should not be taken as an obstacle but as a valuable instrument to achieve that goal.

This article offers a philosophical-empirical account of embodied skilful performance in the practice of plant biotechnology. Drawing on the work of Merleau-Ponty and others, we elaborate how skilful performance emerges from and through reciprocal relations encompassing the body-in-the-world and the world-in-the-body. The contribution of this article lies in offering an account of skilful performance that is attentive to a perceiving, motile, feeling body entwined with world. In genetically modifying plants, scientists direct their senses of touch and vision to manipulating plant (...) materials and matter, ‘reading’ subtle changes in tissue cultures, plantlets and so on. In rhythmic movements, they extend their bodies through skilful use of complex equipment, while calling on ‘intuition’ to guide their work. Skilful performance, then, relies on our lived body that is not merely a physical object among other objects, nor a passive instrument for the mind, but dynamic and inescapably entwined with people and things in a world in flux. Bringing to the fore how perceiving, motile, feeling bodies are implicated in skilful performance has significant implications for education and workplace training. (shrink)

Physical forces regulate numerous biological processes during development, physiology, and pathology. Forces between the external environment and intracellular actin cytoskeleton are primarily transmitted through integrin‐containing focal adhesions and cadherin‐containing adherens junctions. Crosstalk between these complexes is well established and modulates the mechanical landscape of the cell. However, integrins and cadherins constitute large families of adhesion receptors and form multiple complexes by interacting with different ligands, adaptor proteins, and cytoskeletal filaments. Recent findings indicate that integrin‐containing hemidesmosomes oppose force transduction and traction (...) force generation by focal adhesions. The cytolinker plectin mediates this crosstalk by coupling intermediate filaments to the actin cytoskeleton. Similarly, cadherins in desmosomes might modulate force generation by adherens junctions. Moreover, mechanotransduction can be influenced by podosomes, clathrin lattices, and tetraspanin‐enriched microdomains. This review discusses mechanotransduction by multiple integrin‐ and cadherin‐based cell adhesion complexes, which together with the associated cytoskeleton form an integrated network that allows cells to sense, process, and respond to their physical environment.

Finalmente, se determina el listado de categorías que más necesitan trabajar los niños con RL o TDL. (shrink)

The study of agriculture in ancient societies is of vital importance for the understanding of their ecological basis. This article discusses data gathered from Alonso de Molina's dictionary, published in Mexico City in 1571. Molina's information on soil, rain, plants, technology, and human labor applied to agricultural activities gives a picture of the complexity of the several native agricultural systems practiced at that time. Since the Sixteenth Century, native agriculture was impacted by the introduction of new plants, animals, agricultural equipment, (...) and techniques from the Old World. A combination of the two agricultural models conform a new Mexican model of agriculture along the Colonial times. The knowledge of Sixteenth Century agricultural systems is fundamental for the understanding of the history and the conformation of contemporary agro-ecosystems. Recent studies on ecology and social anthropology agree on the necessity to take into account historical data for the discussion of ecological sustainability. (shrink)

Centrándose en (...) la explicación ofrecida a sus colegas galos en De synodis de que el credo del concilio de Ancira de 358 y el homoioúsios no difieren sustancialmente de la comprensión que tienen los partidarios del homooúsios de la relación entre Padre e Hijo aboga por un entendimiento conjunto contra el enemigo común.

This paper attempts to answer whether the property of “efficacy” can be attributed to constitutive rules. In particular, according to Di Lucia, I will point out some problems that the “semantic conception of efficacy” has concerning constitutive and regulative rules. Then, the main goal of the paper will be to reflect on the possibility of the efficacy of constitutive rules by means of a complex case that the semantic conception seems to disregard: The case of the cheater. Does the action (...) of the cheater show the inefficacy of constitutive rules? Does she play the game while breaking the rule? Can the semantic conception of efficacy explain this situation, or do we need a more flexible concept of efficacy that takes nomotropism into account? These are some of the questions I will try to answer. (shrink)

En 1993 y 2012 la poeta irlandesa Mary O’Malley publicó Valparaiso y Where the Rocks Float que edificó alrededor de la figura del mar y de la zona costera irlandesa donde nació. En ambas colecciones, la figura del mar se transforma en un potente agente activo que denuncia el rol de la mujer en la sociedad irlandesa y la explotación de los espacios azules con fines de consumo. Utilizando el análisis de Donna Haraway en Manifiesto cíborg (1985), este artículo analizará (...) una selección de textos de ambos poemarios para estudiar el vínculo entre mujer y mar como agentes activos contra la opresión patriarcal y la explotación capitalista.
