: This work proposes the methodology to obtain a correlation between the particle size of the rock material and the point load test index, in order to characterize the materials, present in mining projects in terms of resistance. For a correct development of mining activities, both open pit and underground, it is important to determine the compressive strength of the rocks, since, through it, geomechanical classifications are obtained, and thus calculate safety factors to define stabilization and/or fortification systems for mining (...) operations. This work was developed on the basis of samples from a geological formation and subsequent preparation of specimens, then they were subjected to physical tests, which can be carried out without problem in the field, and finally, the respective relationships were obtained. The results are encouraging and the equations are proposed to characterize the rock and achieve the proposed objective. Keywords: Rock, Crushing, Classification, Compression. (shrink)

La pandemia de Covid-19 ha puesto a prueba a todos los sistemas de salud. La crisis que provocó ha impactado a la sociedad, economía y, en general, a todas las actividades humanas. Los cuidados paliativos y la bioética tienen un papel fundamental en el manejo de la nueva enfermedad Covid-19, que no tiene aún tratamiento conocido. Los principios de la bioética, sumados a la práctica de los cuidados paliativos han sido el soporte de la pandemia. Los pacientes recuperados y aquellos (...) muertos a causa del Covid-19 han requerido en algún momento de medidas de soporte y paliación, ya sea en unidades hospitalarias o en su domicilio. Es deseable que se impulsen estas herramientas: la paliación y la ética de la vida, ya que no sólo las soluciones que permiten cuidar la vida y la salud provienen de la tecnología, y no deben ser mutuamente excluyentes. A un año del inicio de la pandemia, hay muchas preguntas por responder, mucha investigación por hacer. Sin duda, el año 2020 dará motivos de reflexión a todos los seres humanos y, en especial, a los responsables de cuidar la salud. (shrink)

Los Comités Hospitalarios de Bioética (CHB) tienen la atribución de emitir sugerencias al personal de salud, ante casos clínicos difíciles que involucran problemas y/o dilemas bioéticos. A nivel mundial, y también en México, se encontró poca literatura relacionada, generando en ocasiones cierto grado de incertidumbre en los profesionales de la salud para su resolución. Objetivo: describir los motivos de presentación de casos clínicos de pacientes ante el CHB en un hospital de segundo nivel, desde junio de 2007 a junio de (...) 2018. Método: estudio observacional, descriptivo, retrospectivo y transversal; la muestra fue por conveniencia y se obtuvieron 48 registros de minutas. Resultados: el motivo de consulta más frecuente ante los CHB fue el apoyo en la decisión para la limitación del esfuerzo terapéutico, con 24 casos (50%). Se identificaron 34 dilemas bioéticos (71%) y 14 problemas bioéticos (29%). Conclusiones: ayudará a los servicios médicos tratantes a identificar e intervenir oportunamente, al basarse en situaciones previas sobre dilemas y/o problemas bioéticos. (shrink)

El presente artículo propone una lectura paralela de dos narconovelas colombianas recientes: El ruido de las cosas al caer (2011) de Juan Gabriel Vásquez y El cielo a tiros (2018) de Jorge Franco. El objetivo del análisis consiste en identificar las convergencias entre ambas obras e interpretarlas a la luz de la evolución del paradigma narco vigente en la narrativa colombiana de los años 1990 y 2000.

This article makes an analysis on the role of Jornadinhas Nacionais de Literatura de Passo Fundo, with emphasis on representations of its 4th edition, built by children of 10 years, from the middle class of RS – Ijuí, students of a private school in same municipality. Testimonies of these children are examined at four different times in the light of the Aesthetics of Reception and the Sociology of Reading. The four stages are called placements, a methodology created by Judith Langer (...) and used in this analysis. Thus, this discussion seeks to understand how to make the experience of reading and living of the children mentioned in that moment, in the process of building the 4ª Jornadinha Nacional de Literatura, they intersect and provide representation for the target audience of this work.Este artigo faz uma análise do papel das Jornadinhas Nacionais de Literatura de Passo Fundo, com ênfase nas representações da sua 4ª edição, construídas por crianças de 10 anos de idade, provenientes da classe média de Ijuí – RS, estudantes de uma escola particular no mesmo município. São examinados depoimentos dessas crianças em quatro momentos diferentes, à luz da Estética da Recepção e da Sociologia da Leitura. Os quatro momentos são chamados posicionamentos, uma metodologia criada por Judith Langer e utilizada nesta análise.

O presente artigo lança luz sobre as flutuações semânticas do termo “liberdade” na obra de Leonardo Bruni, buscando nuançar sua apreensão por parte da tradição anglófona de pensamento político conhecida como neorrepublicanismo. A partir da análise conceitual e estilística de diversas passagens centrais da obra do autor florentino, o artigo visa retornar aos usos e significados da palavra “liberdade” em Bruni, colocando a questão da relação entre um âmbito de utilização “teórica” e um âmbito de utilização histórica ou narrativa.

O artigo examina as perspectivas de formação pedagógica de professores, no âmbito da educação profissional no Brasil, olhando-as a partir de resultados de estudos. A investigação consiste em uma análise qualitativa e interpretativa, baseada em uma análise de conteúdo, sobre dissertações e teses voltadas à temática ‘formação pedagógica de professores na educação profissional’, produzidas no período compreendido entre 2005-2015. Este recorte temporal foi estabelecido tendo em vista a expansão dos estudos sobre esta temática, concomitante a expansão da própria educação profissional (...) em nosso país. Os dados foram analisados sob a luz das perspectivas teóricas relacionadas à profissionalidade e constituição docente, esboçadas por Maurice Tardif, José Contreras e José Gimeno Sacristán. Os resultados evidenciaram perspectivas distintas de formação pedagógica docente, das quais duas são discutidas neste artigo: formação profissional docente que prioriza a articulação entre teoria e prática e a complementaridade entre disciplinas e dimensões formativas, na medida em que os docentes reconhecem a importância e valorizam a dimensão pedagógica da formação para a concretização da prática profissional; e formação profissional docente que se concretiza mediante a constituição profissional do professor e a prática pedagógica, visto que para um grupo de professores desta modalidade de educação o conhecimento prático assume centralidade na constituição docente.

Em vista da grande multiplicidade de linguagens e considerando que a alfabetização é uma importante prática de letramento na constituição da criança, este artigo tem o objetivo de identificar o tipo de abordagem dado à imagem em um livro didático do 1º ano, aprovado pelo PNLD. O intuito é discutir em que medida a amostra analisada favorece uma leitura compreensiva e crítica do texto imagético. Para tanto, as ponderações foram realizadas por meio de uma epistemologia interpretativa, à luz da teoria (...) dos letramentos sob uma perspectiva sociocultural, e também a partir da sintaxe da linguagem visual, que pode trazer uma contribuição positiva às análises discursivas visuais. A pesquisa indica que a imagem é proposta a partir de perspectivas socioculturais; que as atividades de leitura favorecem o letramento visual e que a condução do professor pode fazer diferença nas abordagens e leituras.Considering the multitude of languages and the fact that beginning literacy is a key literacy practice in children's education, we aim at identifying how images are approached in a textbook used in the first grade of elementary school and accredited by Brazil's National Textbook Program. We also seek to discuss the extent to which the analyzed sample provides a comprehensive and critical reading of visual texts. The analysis was done based on interpretive epistemology, the sociocultural approach to literacy, and visual language syntax, which can contribute positively to the analysis of visual discourse. We concluded that the image in the sample is presented from sociocultural approaches, that the reading activities foster visual literacy, and that teachers' support plays a significant role in adopting approaches to reading and in conducting reading activities per se.

La fe como elevación del conocer personal. Con el método del abandono del límite mental, Polo descubrió el acceso a la realidad trans-inmanente o trans-operativa del ser humano, alcanzando así el entendimiento agente aristotélico o conocer personal como el conocimiento superior del ser humano.

The paper considers the problem of various different forms of pre‑cognitive affective appraisal and their role in the process of gaining self-knowledge. According to the phenomenological approach, if we are to understand our inner states (our emotional experiences), these cannot be extracted from the context within which they arise. Emotions not only refer to the inner states of the subject, but also to the outer world to which they are a form of response. Brentano, Husserl and Scheler claimed that emotions (...) are directed towards values. It is to this essential feature of emotional experience that I would like to turn. I shall therefore re-examine Sartre’s views concerning affectivity (i.e. the capacity to reveal evaluatively significant qualities of one’s environment), as well as the dual-aspect theory of (reflective and non-reflective) consciousness. The main argument of this paper is that a plausible account of the essential role of affectivity in the emotions may be provided on the basis of a phenomenological theory of pre-reflective consciousness and its relation to reflexivity. I will focus on three different claims about pre-reflective (affective) consciousness. According to the first of these, a large part of cognition is of a prelinguistic (pre-reflective) nature; I argue that the evaluative content of emotion is not only conceptually determined, but may also take a non-conceptual form (as affective appraisal). The second claim refers to the notion of affect, which ought to be distinguished from (unintentional) bodily sensations. The third conceives of the relation between pre-reflective (affective) consciousness and reflective consciousness (propositional attitudes) as normative (rather than causal). I aim to demonstrate that a plausible view of emotional affectivity must appeal to a phenomenological account of the pre-reflective aspect of consciousness. (shrink)

John Dewey’s stay in Tokyo in early 1919 coincided with the height of the social movement calling for parliamentary democracy in Japan. His lectures at Tokyo Imperial University offered a new way of viewing the world and human actions that emphasizes the importance of communication and the growth of democratic personality. Those who expected to hear from him something else were disillusioned. But the disillusionment was mutual. Dewey was disillusioned by the Japanese intellectuals whose affection for European philosophy led them (...) to an uncritical acceptance of the emperor system and Japan’s imperialism abroad. His criticism toward the Japanese intellectuals grew severe as he saw the Japanese aggression while he was on the continent. Dewey’s lecture on democracy left some impact on a few of intellectuals who modified their view of person’s actions that was eventually to be crashed when Japan fell into the all-out war-making.

In the context of medical ethics, how can the concept of informed consent be effectively implemented in a traditional society such as Japan? If the need for more openness and transparency is not felt in the practice of medicine and welfare, the clients must remain under the spell of paternalistic data. Patients and health-care professionals other than doctors are taken to be "responsible for what they do but not to be accountable for their conduct" because they do not participate in (...) a decision-making process. I explore the possibility of the concept's full implementation against the particularists' and communitarian ethicists' effort to reject the universal nature of the concept. (shrink)

In his unpublished 1979 Lectures on the Philosophy of Mind, Saul Kripke offers a knowledge argument against materialism focusing on deaf people who lack knowledge of auditory experience. Kripke's argument is a precursor of Frank Jackson's better‐known knowledge argument against materialism (1982). The paper sets out Kripke's argument, brings out its interest and philosophical importance, and explores some similarities and differences between Kripke's knowledge argument and Jackson's.

El trágico, pero brillante siglo XX, fue un largo periodo de tiempo permeado por enormes problemáticas políticas y económicas, por el albor de las guerras y por los profundos avances científicos, en el que, además, se dejó como hecho histórico, la implementación de la conjugación de las teorías de Charles Robert Darwin sobre la selección natural y los planteamientos de su primo Charles Galton Darwin sobre el proceso natural que se debe seguir para erradicar las deficiencias humanas. Esa conjugación de (...) teorías y planteamientos fueron denominados por Charles Galton en el año de 1883 como “eugenesia” y a través de su aplicación se buscó desde finales del siglo XIX e inicios del siglo XX, que la humanidad debía ser decantada en sus razas más aptas. El objetivo del presente trabajo, a través de una investigación documental y un método cualitativo de análisis, es exponer que las teorías filosóficas de perfeccionamiento de la raza humana reunidas en la eugenesia y usadas en el siglo XX, preponderantemente por el régimen nazi, aún siguen vigentes en los avances científicos de codificación del genoma humano, en las técnicas de reproducción humana asistida y en el diagnóstico genético preimplantacional, de cuyos desarrollos y consecuencias, se acuñó el término de eugenesia liberal.

Uno se acerca a la filosofía a experimentar: al investigar, al construir acuerdos o desacuerdos para la vida, son las palabras las que modulan las diferencias, son ellas las que pueden plasmar una imagen del mundo incitante y diversa. En todas y cada una de sus prácticas la filosofía es un incansable laboratorio de palabras. [Fragmento].

RESUMEN Un atento repaso por la concepción de la violencia chulhaniana en el contexto de las formas tradicionales que han estudiado este fenómeno social permite exponer con mayor detalle y claridad esta propuesta en cuanto a la relación con el otro se refiere. Cuando lo sucedido durante el colonialismo que azotó al mundo en el transcurso de los siglos XVIII y XIX se asumía como las más peligrosas acciones cometidas en procura de la supresión de las características propias de cada (...) uno, en la medida en que los fenómenos de invasión suprimían materialmente la diferencia que poblaba el mundo, apareció la violencia de la positividad como la disposición sistémica que parte de la libertad y el consentimiento individual para, tácitamente, eliminar cualquier tipo de sentido de otredad presente en su constitución. ABSTRACT A careful review of the conception of Chulhanian violence in the context of the traditional forms that have studied this social phenomenon makes it possible to explain in greater detail and clarity this proposal as to the relationship with the other refers. When what happened during colonialism that hit the world during the 18th and 19th centuries was assumed to be the most dangerous actions committed in seeking the suppression of each other's own characteristics to the extent that invasion phenomena materially suppressed the difference that populated the world, the violence of positivity appeared as the systemic disposition that begins with freedom and individual consent to, tacitly, to eliminate any kind of sense of otherness present in its constitution.

In this article, caring, remembering and sharing memory are presented as moral responses, the case study being Alzheimer’s disease (AD). Memory connects memories and images, while care connects individuals, which is an ethical issue. When a person’s memory is lost, the care of others becomes the only thread connecting them to the world. AD deprives a person of memories, body control, makes it impossible to remember, communicate, move, recognize the environment, and disrupts consciousness. Caring for a patient with a neurodegenerative (...) brain disease requires constant reminding and reiteration; the presence of a caring person reminds of what the patient themselves can no longer remember. Lost memories do not mean that life or relational values have also lost their meaning. The description of the memory movement emphasizes the importance of repetition in the moral act. Highlighting the matter of care, also in scientific work, is the aim of this text. To care is to remember, on behalf of the AD patient, about the patient’s life. Within bioethical research, moral responses are an important point for projects which seek to improve the condition of patients—not only the condition of health but also the comfort of life. This improvement will not be possible without attentive, committed caregivers and their responsible attitude in the face of the phenomenon of memory loss. (shrink)

La ética de la responsabilidad planteada por Hans Jonas responde a las demandas tecnocientíficas actuales a través de un imperativo axiológico, mediado por la denominada “heurística del temor”, la prevalencia en la investigación de los pronósticos malos sobre los buenos y la conjunción del bien, el deber y el ser como soporte metafísico de la ética; la cual, aplicada y orientada al futuro, se presenta como una alternativa fiable para guiar los procesos y desarrollos de la tecnociencia, haciendo énfasis en (...) el saber del progreso biomédico sobre el poder de la técnica y apelando a una prudencia responsable.

This essay answers two questions that continue to drive debate in moral and legal philosophy; namely, ‘Is a risk of harm a wrong?’ and ‘Is a risk of harm a harm?’. The essay’s central claim is that to risk harm can be both to wrong and to harm. This stands in contrast to the respective positions of Heidi Hurd and Stephen Perry, whose views represent prominent extremes in this debate about risks. The essay shows that there is at least one (...) category of risks – intentional impositions of risk on unconsenting agents – which can be both wrongful and harmful. The wrongfulness of these risks can be established when, on the balance of reasons, one ought not to impose them. The harmfulness of these risks can be established when the risks are shown to set back legitimate interests. In those cases where risks constitute a denial of the moral status of agents, risks set back agents’ interest in dignity. In these ways, the essay shows that there are instances when a risk can constitute both a wrong and a harm. (shrink)

This paper presents a series of 4 single subject experiments aimed to investigate whether children with autism show more social engagement when interacting with the Nao robot, compared to a human partner in a motor imitation task. The Nao robot imitates gross arm movements of the child in real-time. Different behavioral criteria (i.e. eye gaze, gaze shifting, free initiations and prompted initiations of arm movements, and smile/laughter) were analyzed based on the video data of the interaction. The results are mixed (...) and suggest a high variability in reactions to the Nao robot. The results are as follows: For Child2 and Child3, the results indicate no effect of the Nao robot in any of the target variables. Child1 and Child4 showed more eye gaze and smile/laughter in the interaction with the Nao robot compared to the human partner and Child1 showed a higher frequency of motor initiations in the interaction with the Nao robot compared to the baselines, but not with respect to the human-interaction. The robot proved to be a better facilitator of shared attention only for Child1. Keywords: human-robot interaction; assistive robotics; autism. (shrink)

This paper analyses how the Cold War influenced the discourses on basic research and on Science and Technology Policies of some leaders of the Argentine research community. It explores two key intersections to study the Cold War: the first between politics and policies; the second between the global and the regional/national. The basic assumption is that, just as there was no one Cold War, specific regional and national traits lent specific meanings to basic research. In dialogue with the literature on (...) Latin American history of STPs, on Cold War and on the conceptual history of science, the paper identifies three discursive configurations around S&T: the first refers to the semi-peripheral scientific context; the second is associated with the ‘democracy-totalitarianism’ dichotomy, and the third is linked to the ‘development-dependence’ dichotomy. Finally, the paper also traces some connections between these discourses and the institutional models proposed by different key actors of the research community to implement STPs. (shrink)
