There and back again. Heidegger and Tolkien on technology

The purpose of this paper is to analyze Tolkien’s and Heidegger’s thoughts on technology with the aim of justifying that the metaphysical/ontological position of the second brings problems regarding the solution of the problem concerning technology that can be easily solved if one opts for a Tolkienian approach to the problem, that is, from a rather mundane or everyday dimension of humanity (or “hobbitry”, to be more precise).The purpose of this paper is to analyze Tolkien’s and Heidegger’s thoughts on technology with the aim of justifying that the metaphysical/ontological position of the second brings problems regarding the solution of the problem concerning technology that can be easily solved if one opts for a Tolkienian approach to the problem, that is, from a rather mundane or everyday dimension of humanity (or “hobbitry”, to be more precise)

The Role of Knowledge Management in Supply Chain Management: A Literature Review

Purpose: The aim of this paper is to examine the state of knowledge management research in supply chain management from three standpoints, methodological approach, supply chain management area, and knowledge management processes. Design/methodology/approach: To achieve this, a systematic review is conducted over the period 2000-2014 on the basis of a qualitative content analysis. Findings: Major results showed that knowledge management can be viewed as a leverage mechanism for: (i) supply chain integration; (ii) the enhancement of intra and inter-relations across the supply chain; (iii) supply chain strategy alignment; and (iv) the reinforcement of knowledge transfer in product development. Some supply chain management areas such as reverse logistics, inventory management, forecasting/demand planning, outsourcing, and risk management have been explored only to some extent. Furthermore, knowledge transfer is being studied in the majority of the articles, mainly by both case study and survey approach; mathematical models and simulation techniques are used in very limited articles. Findings concerning theoretical perspectives and managerial issues are also described. Research limitations/implications: The limitation of our study encompasses the aspects of search period (2000-2014), selection of search databases (Web of Science and SCOPUS and language selection (English). Practical implications: The exhibition of the KM processes within the SC context may help practitioners and managers interested in implementing KM initiatives to replicate the methodologies in order to increase the possibilities of a successful KM adoption. Originality/value: The systematic review will contribute to the understanding of the present state of research in the knowledge management theory, with focus on the supply chain, as there are no state-of-knowledge studies that report a systematic literature review approach.Peer Reviewe

Stellar-Mass Black Holes in the Solar Neighborhood

We search for nearby, isolated, accreting, ``stellar-mass'' (3 to $100M_\odot$) black holes. Models suggest a synchrotron spectrum in visible wavelengths and some emission in X-ray wavelengths. Of 3.7 million objects in the Sloan Digital Sky Survey Early Data Release, about 150,000 objects have colors and properties consistent with such a spectrum, and 87 of these objects are X-ray sources from the ROSAT All Sky Survey. Thirty-two of these have been confirmed not to be black-holes using optical spectra. We give the positions and colors of these 55 black-hole candidates, and quantitatively rank them on their likelihood to be black holes. We discuss uncertainties the expected number of sources, and the contribution of blackholes to local dark matter.Comment: Replaced with version accepted by ApJ. 40 pages, 8 figure

Des résultats en français issus d’une recherche à propos de l'écriture de récits historiens au primaire : comment les interpréter ?

Cette communication porte sur un projet d’histoire orale, dans le cadre duquel 26 élèves du primaire d’une classe multiâges (10-13 ans) de Québec ont mené des entrevues avec leurs grands-parents, avant d’écrire un récit de la vie de ces derniers. L’analyse repose sur un double cadrage théorique relatif à l'écriture historienne ou historical writing et l'écriture littéraire. Elle permet de mettre en évidence des traces de plusieurs habiletés ou catégories, principalement d'ordre temporel ou causal, liées au genre narratif qu'est le récit historique (Coffin, 2006) ou à l'écriture argumentative propre à l'historien (De La Paz, 2012; De La Paz e.a., 2014; Jadoulle, 2015; Monte-Sano & De La Paz, 2012). L'examen des mêmes récits révèle des indices d'un travail d'écriture littéraire tel que défini par Dufays (2019) autour de quatre catégories : cognitive, éthique, référentielle et esthétique

Prevalencia de obesidad pre-sarcopénica en personas mayores chilenas: Resultados de la Encuesta Nacional de Salud 2016-2017

Introduction: There are no studies in Chile that quantify the prevalence of pre-sarcopenic obesity. Therefore, this study aimed to determine the prevalence of pre-sarcopenic obesity in Chilean elderly people. Methodology: 240 people ≥ 60 years from the Chilean National Health Survey 2016-2017 were included. Pre-sarcopenia was estimated with the handgrip test and obesity was defined using waist circumference. As a sensitivity analysis, obesity was classified in a subsample of 129 people using the BMI. Based on the obesity and muscle strength criteria, the participants were categorized as: normal; obese/ normal; normal/pre-sarcopenia and obesity/pre-sarcopenia. Results: 22.6% of the population presented obesity/pre-sarcopenia using waist circumference as a diagnostic parameter. The prevalence of pre-sarcopenic obesity was higher in women (22.9%), in older people (33.0%), with urban residence (22.8%), and lower educational levels (37.3%). By incorporating the BMI as an obesity criterion, a decrease in the prevalence of pre-sarcopenic obesity (12.2%) and a higher percentage of women with this phenotype were identified. Conclusions: The prevalence of pre-sarcopenic obesity was identified in 22.6% of the older Chilean population included. Considering the role of obesity and sarcopenia in the development of non-communicable diseases, its identification and early detection could allow the creation of interventions that favor the survival and health of the elderly.Introducción: No existen estudio en Chile que cuantifiquen la prevalencia de obesidad pre-sarcopénica.  Por ende, el objetivo de este estudio fue determinar la prevalencia de obesidad pre-sarcopénica en personas mayores chilenas. Metodología: Se incluyeron 240 personas ≥ 60 años de la Encuesta Nacional de Salud (ENS) 2016-2017 de Chile. La pre-sarcopenia se estimó con la prueba de prensión manual y la obesidad fue definida utilizando la obesidad abdominal través de la medición del perímetro de cintura. Como análisis de sensibilidad, en una submuestra de 129 personas se clasificó la obesidad utilizando el IMC. En función de los criterios de obesidad y fuerza muscular los participantes fueron clasificados en 4 categorías: normal; obeso/ normal; normal/ pre-sarcopenia y obesidad/ pre-sarcopénica. Resultados: Un 22,6% de la población estudiada presentaba obesidad/pre-sarcopénica usando el perímetro de cintura como parámetro diagnóstico. Además, la prevalencia de obesidad pre-sarcopénica fue mayor en mujeres (22,9%), en personas con mayor edad (33,0%), con residencia urbana (22,8%), y menor nivel educacional (37,3%). Al incorporar el IMC como criterio de obesidad, se identificó una disminución de la prevalencia de obesidad pre-sarcopénica (12,2%) y un porcentaje mayor de mujeres con este fenotipo. Conclusiones: Se identificó una prevalencia de 22,6% de obesidad pre-sarcopénica en población mayor chilena. Considerando el rol de la obesidad y sarcopenia en el aumento de enfermedades crónicas no transmisibles, su identificación y detección temprana podría permitir la creación de intervenciones que favorezcan la supervivencia y la salud de las personas mayores

La técnica y el acabamiento de la metafísica occidental

Este trabajo tiene por finalidad reconstruir la línea argumentativa que sigue Heidegger en su obra Nietzsche sobre la relación entre el pensamiento de la voluntad de poder y la técnica moderna, el cual es enunciado por Heidegger en dicha obra, pero no desarrollado de manera sistemática
