This paper employs network theory, mining data and bibliometric analysis when mapping the scientific contribution of Nobel Prize candidate; Manuel Sandoval Vallarta, the first and most renowned Mexican physicist and important figure in Latin American science. Vallarta died in 1977, and the existing literature is about his life and contributions to science but not about how those are still valuable today. This paper is the first to highlight, with mapping tools, that his contributions are relevant to the international community of (...) cosmic rays, quantum mechanics and relativity. These tools delivered three findings: Identify how he built his own field of study, same as universal knowledge. Unveil that the backward and forward Vallarta citations follow a scale-free network distribution. Determine social factors that benefited or affected his scientific activities—such as World War II interrupting Vallarta’s successful productivity at Massachusetts Institute of Technology. Furthermore, this study confirmed the interdisciplinary nature of the mapping studies of the scientist's contributions using scientometric tools. As a result, several interesting questions arose throughout our research, some of which were answered from the history and philosophy of science. However, others need to be analyzed by experts in the fields of Vallarta. Mapping research sends an invitation to interdisciplinary dialogue/research between experts in different areas of study to better understand the process of knowledge production both, individual and collective.

We aimed to characterize the age of onset of training, age at menarche, menstrual periodicity, and performance perception during the menstrual cycle and examined the impact of these reproductive variables on body composition, morphology, and body weight satisfaction in Brazilian elite futsal players. The study consisted of 115 female Brazilian elite futsal players from the top national teams. Data were collected during the twentieth Women’s Brazil Futsal Cup. Players were interviewed and self-reported their age of onset of training, age at (...) menarche, menstrual periodicity, and the menstrual period, where they performed best. We also asked for what they considered to be their ideal body weight as well as information related to their training. Subsequently, anthropometric measurements were performed to estimate the body composition and determine morphological characteristics. Fifty-nine players were postmenarche-trained and 52 were premenarche-trained. Eighteen, 65, and 28 were classified as early, normal, and late menarche, respectively. Only 11 and 1 had irregular menstrual cycles and were amenorrheic, respectively. Seventy-three, 23, and 9 reported that their game performance was the best at the follicular phase, menses, and luteal phase of the menstrual cycle, respectively. No associations between the four reproductive-related variables were found. Postmenarche-trained players had significant lower age at menarche and higher percentage body fat. The somatotype profile registered lower ectomorphy rate for the postmenarche-trained participants after controlling for covariates. Early menarche group presented higher sum of six skinfold thickness and endomorphy rate compared to normal and late menarche groups. No differences were found when menstrual periodicity groups and best performance groups were compared, except for higher femur width in the regular menstrual cycle group compared to the irregular one. The association between body weight satisfaction and the four reproductive-related variables were not observed. Premenarche-trained Brazilian elite futsal players had the menarche later than the postmenarche-trained athletes. Most of the participants had menarche age classified as “normal,” presented “regular” menstrual cycles and perceived to perform better during the follicular phase of the menstrual cycle. (shrink)

Los cuatro filósofos que aquí se discuten parecen mostrar cuatro caminos de búsqueda que si no siempre conducen a un Dios vivo, por lo menos son un intento por alcanzarlo o una nostalgia de loa alcanzable y, por lo mismo, presente. ¿Es necesario que la ciencia se oponga a la religión? Teilhard de Chardin, en una experiencia cristiana nunca puesta en duda, trata de reunir y unificar ciencia y conciencia o, si se requiere, en términos tan viejos como vigentes, razón (...) (ciencia) y fe (la cristiana). ¿Existe la posibilidad de conocer a los "celestes", e incluso a Dios? A la pregunta contestará dubitativamente pero no sin esperanza Martín Heidegger. ¿Es importante la vida religiosa para quien, acongojadamente, descree? Lo es para alguien que, como Wittgenstein, ha perdido la fe y, sin embargo, anda en busca de lo indecible, de lo "místico". ¿Tienen todavía vigencia tratar de reunir la Grecia clásica y el universo cristiano, por vías místicas? La respuesta será afirmativa en esta obrera de la gracia y el amor que fue Simone Weil. (shrink)

En el año 1986 Diego Gracia publicó el libro `Voluntad de verdad: Para leer a Zubiri`, que pronto se consagró como la obra de referencia para una primera introducción al pensamiento del filósofo español. Pero han pasado desde entonces treinta años, las obras publicadas de Zubiri y sobre Zubiri se han multiplicado, su interpretación ha ido evolucionando y el conocimiento sobre él es cada vez más amplio y profundo. Ya no es hora de hacer introducciones a su filosofía sino (...) análisis detallados y críticos de la misma. Eso es lo que Gracia ha intentado en múltiples trabajos sobre el tema publicados en diferentes lugares a lo largo de estas tres décadas (y en algunos que se publican por primera vez aquí). Antonio Pintor-Ramos se ha encargado de revisar todos esos trabajos, seleccionarlos, ordenarlos y formar con ellos el presente volumen, que ha resultado no ser una simple recopilación de textos sino un libro perfectamente organizado y sistemático. Esta obra ofrece, por tanto, una revisión actual del pensamiento de Zubiri, profunda y detallada, que sintetiza las diversas interpretaciones realizadas sobre él a la vez que expone con argumentos la que el propio Gracia asume como suya.

El objetivo de este artículo es poner de relieve la importancia filosófica del tema de los valores dentro de la obra de Diego Gracia. Aunque surgida en el camino de búsqueda de una fundamentación para los principios de la Bioética, esta Filosofía de los Valores es un capítulo con valor autónomo y poco atendido, aunque probablemente sea la elaboración filosóficamente más relevante de su autor. Se contextualiza, se analiza su desarrollo filosófico y se pone de relieve que la constante (...) referencia a la filosofía de Zubiri significa no una glosa o comentario, sino una prolongación y creación originales, cuyo objetivo es colocarse fuera de la dicotomía entre objetivistas y emotivistas. Apoyándose en recursos tomados de Zubiri, Gracia elabora una doctrina “constructivista” de los valores y piensa esquivar el peligro del relativismo enraizando el valor en la formalidad de realidad. El tema tiene interés por sí mismo y merece tomarse en consideración, al margen de su rendimiento en el campo de la Ética. (shrink)

Adela Cortina, doctora Honoris Causa, es un referente indiscutible en el ámbito de la ética. En sus primeras obras ya se indicaba la necesidad de encontrar unos mínimos cívicos, un conjunto de valores y principios para una convivencia pacífica entre ciudadanos con distintas morales, gracias a los cuales construir modos ideales particulares de vida buena. Para descubrir esos mínimos optó por el procedimentalismo dialógico. Ahora bien, durante los años ha ido reflexionando sobre ese procedimentalismo para hacer un análisis más completo (...) del vínculo comunicativo. Y eso fue lo que pretendió con sus obras centradas en desarrollar una ética cordis. Como bien sostiene, «quien tenga voluntad de justicia, voluntad de descubrir mediante el diálogo qué es lo justo, está obligado a trabajar activamente por la defensa de los derechos humanos y las capacidades básicas de los afectados».

In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

O escopo de nosso artigo restringe-se à proposição de uma crítica à teoria da complexidade quanto ao seu pressuposto ontológico: realidade complexa e à inalação decorrente de tal pressuposto; a necessidade de uma ciência da complexidade. Essa crítica visa apontar, por um lado, as insuficiências da referida teoria, marcada por um forte apelo metafísico, quando essa pretende estabelecer um conhecimento a priori e inédito apoiado supostamente num dado empírico ou mais precisamente na complexidade do real. Por outro, nossa crítica tenta (...) desconstruir parte dos argumentos da teoria da complexidade voltados à generalização de certos modelo complexos – empreendidos em alguns ramos do saber científico – enquanto subterfúgio para a constituição de uma teoria geral da ciência. Assim, defendermos a idéia de que quando não retoma pressuposto da tradição metafísica – a ontologia determina a epistemologia; já invalidados porque recorrem ao mythy of given – a teoria da complexidade incorre na grave falhe de determinar o modus operandis da ciência a partir de uma teoria metacientífica, inexeqüível experimentalmente.

While children’s experiences of online risks and harm is a growing area of research in New Zealand, public discussion on the matter has largely been informed by mainstream media’s fixation on the dangers of technology. At best, debate on risks online has relied on overseas evidence. However, insights reflecting the New Zealand context and based on representative data are still needed to guide policy discussion, create awareness, and inform the implementation of prevention and support programmes for children. This research report (...) presents findings from a quantitative study regarding different aspects related to risks and online safety. It looks at the online experiences that children find bothersome and upsetting and explores the hurtful behaviours they encounter or engage in, both online and in person. Evidence regarding exposure to different types of potentially harmful online content is also presented. Another relevant contribution is the insights related to excessive internet use.The findings presented in this report are based on data from 2,061 New Zealand children aged 9-17. We hope the findings will contribute to the development of policies, practices and services designed to support New Zealand children to safely take advantage of the opportunities available to them online.

Mental state reasoning or theory-of-mind has been the subject of a rich body of imaging research. Although such investigations routinely tap a common set of regions, the precise function of each area remains a contentious matter. With the help of functional magnetic resonance imaging (fMRI), we sought to determine which areas are involved when processing mental state or intentional metarepresentations by focusing on the relational aspect of such representations. Using non-intentional relational representations such as spatial relations between persons and between (...) objects as a contrast, the results ascertained the involvement of the precuneus, the temporal poles, and the medial prefrontal cortex in the processing of intentional representations. In contrast, the anterior superior temporal sulcus and the left temporo-parietal junction were implicated when processing representations that refer to the presence of persons in relational contexts in general. The right temporo-parietal junction, however, was specifically activated for persons entering spatial relations. The level of representational complexity, a previously unexplored factor, was also found to modulate the neural response in some brain regions, such as the medial prefrontal cortex and the right temporo-parietal junction. These findings highlight the need to take into account the critical roles played by an extensive network of neural regions during mental state reasoning. (shrink)
