The emergence of collective intelligence has been studied in much greater detail in small groups than in larger ones. Nevertheless, in groups of several hundreds or thousands of members, it is well-known that the social environment exerts a considerable influence on individual behavior. A few recent papers have dealt with some aspects of large group situations, but have not provided an in-depth analysis of the role of interactions among the members of a group in the creation of ideas, as well (...) as the group’s overall performance. In this study, we report an experiment where a large set of individuals, i.e., 789 high-school students, cooperated online in real time to solve two different examinations on a specifically designed platform (Thinkhub). Our goal of this paper 6 to describe the specific mechanisms of idea creation we were able to observe and to measure the group’s performance as a whole. When we deal with communication networks featuring a large number of interacting entities, it seems natural to model the set as a complex system by resorting to the tools of statistical mechanics. Our experiment shows how an interaction in small groups that increase in size over several phases, leading to a final phase where the students are confronted with the most popular answers of the previous phases, is capable of producing high-quality answers to all examination questions, whereby the last phase plays a crucial role. Our experiment likewise shows that a group’s performance in such a task progresses in a linear manner in parallel with the size of the group. Finally, we show that the controlled interaction and dynamics foreseen in the system can reduce the spread of “fake news” within the group. (shrink)

En el presente artículo evalúo el concepto de violencia, explorando casos hipotéticos que permitan establecer cuáles son las condiciones o criterios que muestran cuándo una acción puede ser calificada como violenta. Frente a esto, parto de la idea de que una acción es violenta cuando rompe reglas o normas, las cuales son establecidas por sistemas sociales que se fundan en sistema de creencias. Concluyo, así, que hay que examinar los sistemas de creencias, donde se fundan los sistemas sociales, para erradicar (...) todo tipo de acción que pueda romper reglas o normas. (shrink)

In this paper I focus my attention on the proposal given by Howard Wettstein in 1980 to the cognitive phenomenon stated by Gottlob Frege in his paper “On sense and reference”. I offer three arguments in order to show that his answer does not weaken this phenomenon. Particularly, I defend three ideas: first, it is legitimate that philosophical semantics, in contrast with what Wettstein defends, provides an answer to the cognitive phenomenon; second, Wettstein does not conceive Frege’s argument correctly by (...) considering it generates a semantic theory from a purely mentalist phenomenon; third, the explanation supplied by Wettstein is assumed by Frege when he states the phenomenon.

Actualmente, somos integrantes de la Red de Educadores Matemáticos Críticos (REDUMAC) y encontramos relevante, estudiar los caminos transitados, los desafíos que hemos asumido con la intención de transformar las prácticas matemáticas desde la escuela, así como hacer evidente las posibilidades de nuestra apuesta teórica, metodológica y las formas de trabajo como colectivo de maestros. Este colectivo surge del interés y preocupación de profesionales en educación por continuar la formación que habíamos puesto en marcha desde el desarrollo de nuestros trabajos de (...) grado de maestría bajo perspectivas sociopolíticas y de la política cultural de la educación matemática retomando inicialmente postulados de la Educación Matemática Crítica (EMC). El desarrollo de las prácticas pedagógicas propuestas que hemos gestado ha girado en torno al diseño de escenarios de aprendizaje y de ambientes de modelación matemática. Sustentados en estas ideas teóricas, REDUMAC busca generar espacios desde los cuales los profesores continuemos profundizando y reflexionando las ideas que trabajamos en nuestras investigaciones, encontrando intereses comunes con otros compañeros. De esta manera, buscamos posicionarnos y actuar críticamente en nuestro rol como profesores e investigadores desde el campo de la educación matemática para pensar y reflexionar sobre las problemáticas que vinculan la escuela, la universidad y la sociedad. Nuestro objetivo es continuar consolidándonos como red y como espacio de formación continuada de profesores, desde un proceso autónomo que surge de los propios intereses de sus participantes, y que quiere vincular a más profesores e investigadores del país que tengan esas mismas intencionalidades. Con este escrito, buscamos no solo invitar a la comunidad a poner en discusión esta preocupación, sino dar a conocer la experiencia en formación continuada de profesores de matemáticas que hemos venido explorando, construyendo y consolidando desde espacios de autoformación. Para lograrlo, hacemos un proceso reflexivo y de autoconocimiento para identificar los caminos que hemos transitado, las posibilidades y los retos que venimos asumiendo desde nuestro trabajo colaborativo, buscando otros mundos posibles que vinculen la educación matemática y la realidad social de nuestro país. De esta manera, iniciamos el artículo con un apartado en el cual argumentamos la relevancia de retomar el camino de REDUMAC, posteriormente, reconstruimos en detalle nuestra historia, y en un tercer apartado, profundizamos en las estrategias de trabajo que hacen particular a este colectivo de maestros. Para finalizar, relatamos los caminos recorridos, los logros alcanzados, los aprendizajes construidos, las posibilidades que encontramos a futuro para nuestro colectivo y para iniciativas que se puedan gestar en estas líneas.

Resumen En esta nota crítica presento un análisis de los materiales textuales que constituyen el capítulo 19 de la serie Early Greek Philosophy de A. Laks y G. Most dedicado a Parménides. Después de comparar cuantitativamente los textos de este capítulo con las ediciones de H. Diels y A.H. Coxon, así como de precisar cuáles son los textos "nuevos" que figuran en esta edición y las formas en que los editores decidieron presentarlos, ofrezco algunas consideraciones sobre el concepto mismo de (...) recepción y su operatividad en este capítulo, sobre la superación definitiva de la distinción entre testimonios y fragmentos y sobre las ventajas y desventajas que supone cortar los textos para la presentación esquemática y temática de los contenidos. Por último, examino el modo en que la doctrina de Parménides se presenta en este capítulo y muestro algunas de las decisiones que los autores tomaron sobre los innumerables problemas de transmisión textual del Poema.In this critical note, I will present an analysis of the textual materials that constitute the 19th chapter, dedicated to Parmenides, of the Early Greek Philosophy series by A. Laks and G. Most. After offering a quantitative comparison of the texts in this chapter and the editions of H. Diels and A.H. Coxon, and after specifying which "new" texts figure in this edition and how they are presented, I will provide considerations on the concept of reception and how it operates throughout this chapter, on the definite overcoming of the distinction between testimonia and fragmenta, and on the advantages and disadvantages of cutting out the texts for the schematic and thematic presentation of its contents. Finally, I examine how Parmenides' doctrine is presented and comment on some of the decisions that the authors made on a few of the innumerable problems related to the textual transmission of the Poem.

In this paper we mainly study preservation theorems for two fragments of the infinitary languagesLκκ, withκregular, without the equality symbol: the universal Horn fragment and the universal strict Horn fragment. In particular, whenκisω, we obtain the corresponding theorems for the first-order case.The universal Horn fragment of first-order logic (with equality) has been extensively studied; for references see [10], [7] and [8]. But the universal Horn fragment without equality, used frequently in logic programming, has received much less attention from the model (...) theoretic point of view. At least to our knowledge, the problem of obtaining preservation results for it has not been studied before by model theorists. In spite of this, in the field of abstract algebraic logic we find a theorem which, properly translated, is a preservation result for the strict universal Horn fragment of infinitary languages without equality which, apart from function symbols, have only a unary relation symbol. This theorem is due to J. Czelakowski; see [5], Theorem 6.1, and [6], Theorem 5.1. A. Torrens [12] also has an unpublished result dealing with matrices of sequent calculi which, properly translated, is a preservation result for the strict universal Horn fragment of a first-order language. And in [2] of W. J. Blok and D. Pigozzi we find Corollary 6.3 which properly translated corresponds to our Corollary 19, but for the case of a first-order language that apart from its function symbols has only oneκ-ary relation symbol, and for strict universal Horn sentences. The study of these results is the basis for the present work. In the last part of the paper, Section 4, we will make these connections clear and obtain some of these results from our theorems. In this way we hope to make clear two things: (1) The field of abstract algebraic logic can be seen, in part, as a disguised study of universal Horn logic without equality and so has an added interest. (2) A general study of universal Horn logic without equality from a model theoretic point of view can be of help in the field of abstract algebraic logic. (shrink)

The stream on political corporate social responsibility argues that companies have recently assumed state-like roles to influence global governance. However, following emerging calls for greater contextualization of CSR, we trace the historic evolution of PCSR in the case of Colombia and argue that such political engagement by firms is not new. Looking beyond a linear chronological account, we reveal the sedimentation process behind PCSR by exploring the archetypical political roles businesses have taken on in providing public goods and acting as (...) regulators, and chart their transformation. Our findings allow us to make two main contributions. First, by unearthing different strata of business and society relations, we enrich the research on PCSR, highlighting its historical sedimentation dynamics. By integrating institutional and historical perspectives, we respond to calls for complementary accounts of one of the premises found in the literature that considers globalization as the starting point of PCSR. Second, our exploration of the past and present of PCSR in Colombia provides scholars and practitioners with an overview of the complex state and stakes of CSR in that country. We also discuss the implications of sedimentation for PCSR theory and future research directions. (shrink)

La concepción platónica de las experiencias visual y auditiva en un doble nivel repercute en su propuesta educativa y política, expresada, entre otros diálogos, en República. Un estudio filológico de estos campos semánticos en el Libro VIII e inicio del Libro IX de República permite postular que, para el ateniense, los cambios en las formas de la polis están ligados a cambios en los modos de ver y oír humanos. Así, el desplazamiento puede producirse desde una mirada y audición profundas (...) a una mirada y audición superficiales, desde un oír- ver unitarios a múltiples, o del ver y oír al no-ver ni oír. En todos los casos,este desplazamiento tiene como correlato un desplazamiento en las formas de organización de la polis. (shrink)

Critical aspects in the field of education are currently related to low levels of socioemotional competences and high rates of school dropouts. However, there are no standard practices or guidelines for helping countries to assess and train social and emotional competences. To overcome this limitation, the project Learning to be (L2B) aims to propose a comprehensive model of the assessment and development of social and emotional competences that bring together policymakers, researchers, teachers, school authorities and learners from different participating countries: (...) Finland, Italy, Latvia, Lithuania, Portugal, Slovenia, and Spain. The project attempts to create an international framework for regulating activities and supporting teachers working on the social and emotional competences of the students and to provide tools which can be used across countries. The aim of the paper is to describe how L2B has been developed in Spain by analyzing the contributions of the international framework and extracting the specific needs in the Spanish context. Specifically, we describe two products of the project: a) the process for creating a toolkit, a tool focused on creating activities and materials for helping teachers develop social and emotional competences of students and b) the results of an exploratory study in Spain in which social and emotional competences are assessed and compared to the international framework. First, we explain the definition of social and emotional competences used for creating the toolkit. Second, we analyze responses of Spanish students to questionnaires administered before applying the toolkit in the schools. The paper describes social and emotional competences in Spain and evaluates the overlap between relevant variables in Spain and those used for developing the toolkit, the international tool. Specific needs in Spain are discussed, as well as the contribution of the project for promoting the improved development of students’ social and emotional competences, improving learning outcomes and stronger social cohesion in schools and local communities, as well as the utility of the results for creating new educational policies.

Human genomics is a translational field spanning research, clinical care, public health, and direct-to-consumer testing. However, law differs across these domains on issues including liability, consent, promoting quality of analysis and interpretation, and safeguarding privacy. Genomic activities crossing domains can thus encounter confusion and conflicts among these approaches. This paper suggests how to resolve these conflicts while protecting the rights and interests of individuals sequenced. Translational genomics requires this more translational approach to law.

RESUMEN El artículo responde algunas críticas planteadas por Ignacio Ávila a mi interpretación de la epistemología davidsoniana. Presento argumentos en contra de: a) que sea necesario distinguir entre representaciones epistemológicamente “peligrosas”e “inofensivas”; b) que el empirismo mínimo sea un tipo de realismo directo; c) que mi uso de la expresión “evidencia distal” y el interés por la teoría de la correspondencia sean asuntos ajenos a Davidson. Finalmente, sostengo que la triangulación es un elemento fundamental de la epistemología davidsoniana, pues permite (...) sortear la ansiedad realista manteniéndose en una postura no representacionalista. ABSTRACT In this article, I respond to some of Ignacio Ávila's criticisms of my interpretation of Davidson’s epistemology. I argue against: a) the need to distinguish between epistemologically “dangerous” and “harmless” representations; b) the idea that minimal empiricism is a kind of direct realism; and c) the claim that my usage of the expression “distal evidence” and interest in the theory of correspondence are issues that do not pertain to Davidson. Finally, I claim that triangulation is a key element in Davidsonian epistemology since it allows us to deal with the realist anxiety while maintaining a non-representationalist viewpoint. (shrink)

La erosión de la confianza en las capacidades epistémicas de la ciudadanía tiene en su raíz la radical separación entre hechos y valores que el pragmatismo ha considerado como clave de nuestra cultura. Hoy es posible superar el dualismo sobre la base de un conjunto de virtudes y disposiciones individuales que son tanto éticas como epistémicas. Este entrelazamiento entre lo ético y lo epistémico pone de manifiesto la imbricación entre una concepción deliberativa de la democracia con su exigencia de una (...) ética cívica y los requerimientos de una ética de la investigación científica en el marco de una sociedad democrática.

Partiendo de los análisis de los epistemólogos de la virtud que sitúan la mentalidad abierta como virtud epistémica central el artículo muestra el indisoluble entrelazamiento entre sus dimensiones éticas y epistémicas. Se entiende la mentalidad abierta como virtud de acuerdo con una concepción falibilista de la experiencia y el conocimiento humano en el que se acentúa la capacidad de intervención del agente a través de sus disposiciones y hábitos. Finalmente, la argumentación conduce a una defensa ética del liberalismo político.

Este trabajo interpreta el auge de los códigos éticos y de la ética profesional desde el punto de vista de su contribución a la formación de una ciudadanía democrática. Se analizan diversos aspectos de la ética profesional desde la perspectiva de una ética del agente para la que bienes, normas y virtudes resultan factores complementarios para el cultivo de la inteligencia y el juicio individual. A través de una concepción de la democracia que la vincula con los hábitos y modos (...) de vida, la ética profesional adquiere una renovada significación como elemento central para la autorrealización personal y la emancipación social. En definitiva, bajo el rótulo del profesionalismo democrático, y de la mano de la filosofía moral y política de Dewey, se muestra que la ética profesional es más que un campo de aplicación, un elemento constituyente de una ética cívica en el marco de una sociedad democrática.

Our work is a contribution to the model theory of fuzzy predicate logics. In this paper we characterize elementary equivalence between models of fuzzy predicate logic using elementary mappings. Refining the method of diagrams we give a solution to an open problem of Hájek and Cintula (J Symb Log 71(3):863–880, 2006, Conjectures 1 and 2). We investigate also the properties of elementary extensions in witnessed and quasi-witnessed theories, generalizing some results of Section 7 of Hájek and Cintula (J Symb Log (...) 71(3):863–880, 2006) and of Section 4 of Cerami and Esteva (Arch Math Log 50(5/6):625–641, 2011) to non-exhaustive models.

In Dellunde et al. 997–1015), we determined the complete theory Te of modules of separably closed fields of characteristic p and imperfection degree e, eω{∞}. Here, for 0≠eω, we describe the closed set of the Ziegler spectrum corresponding to Te. Further, we establish a correspondence between certain submodules and n-types and we investigate several notions of dimensions and their relationships with the Lascar rank. Finally, we show that Te has uniform p.p. elimination of imaginaries and deduce uniform weak elimination of (...) imaginaries. (shrink)

The flowers of the primitive angiosperm plants were radially symmetrical (actinomorphic). Flowers with bilateral symmetry (zygomorphic) evolved in several clades independently as an adaptation to specialized methods of pollination and played an important role in the diversification of flowering plants. In the model species Antirrhinum majus (snapdragon), the related genes CYCLOIDEA (CYC) and DICHOTOMA (DICH) are key in the development of this trait. This raises the question of whether they played a role in the evolution of floral bilateral symmetry. To (...) address this, the evolution of CYC in relation to the evolution of zygomorphy is being investigated. Phylogenetic and functional analyses of CYC‐like genes are being carried out in groups either closely related to Antirhinum or in families where zygomorphy evolved as an independent event. In addition, the origin of zygomorphy is being studied by comparing the function of CYC‐like genes in species with zygomorphic flowers with their function in species with radially symmetrical flowers.

ABSTRACT My aim in this paper is to present a pluralist thesis about the inferential role of logical constants, which embraces classical, relevant, linear and ordered logic. That is, I defend that a logical constant c has more than one correct inferential role. The thesis depends on a particular interpretation of substructural logics' vocabulary, according to which classical logic captures the literal meaning of logical constants and substructural logics encode a pragmatically enriched sense of those connectives. The paper is divided (...) into four parts: first, I introduce the motivation for the pluralist thesis of the paper; second I introduce the calculus for the different logics endorsed in the pluralist thesis; third, I motivate how the different behaviors of the logical vocabulary of these logics can be pragmatically interpreted, and fourth, I motivate how the different inferential roles that each substructural logic attribute to logical constants can coexist, and how we should reason with a logical constant c given this plurality.
