Portrait painting is one of the most direct sources of study because of its challenge to temporal limits, since at first instance no effort is required to decode the image. This immediate connection between the observer and the painting itself is even more evident when studying baroque representations. The portraits in the painting Las meninas are an eloquent testimony of that willingness to begin a dialogue created in the past and continued in the present with a back drop acting as (...) a mirror and a chamber of wonders. The silent dialogue gives voice and prominence to the girls and jesters from a perspective that we define today as metapictorial. (shrink)

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

Los avances de la biotecnología y las fascinantes perspectivas de la genómica nutricional en el escenario de la práctica clínica conducen a la consideración de distintos aspectos que impactan en el beneficio integral del ser humano. En ese sentido, la integración de la nutrición personalizada en la atención clínica requiere de un análisis bioético centrado en la unidad de la persona que, con base en su perfil nutrigenético único, contribuya al cuidado de la salud por medio del tratamiento nutricional individualizado. (...) El análisis bioético contempla los principios de totalidad terapéutica, libertad e integridad. Además, el uso de las pruebas nutrigenéticas destaca no solo la confidencialidad de datos, que se presupone, sino que lleva a considerar el derecho a la intimidad. (shrink)

Las vanguardias artísticas nacieron insertas en un mundo de cambios para destronar un sistema de órdenes que estaban en decadencia. En los inicios del XX se experimentó la primera gran crisis del canon estético que hasta entonces definía el arte, los vanguardistas lo cuestionaron provocando la ruptura del discurso narrativo tradicional y lo reinventaron hasta convertirlo en uno de los pilares del mundo contemporáneo, abriendo una puerta desde lo imposible a lo posible. Como se verá en este artículo, debido a (...) su sentido crítico, la obra de Nietzsche fue capaz de anticipar las coordenadas generales de las vanguardias con los ejes de su pensamiento: el nihilismo, la dicotomía dionisiaca/apolínea y la voluntad de poder como conceptos clave para comprender su génesis, el proceso de acción artística y su sentido. Para ello se recorrerá su obra en sus distintas etapas, y se interrelacionarán con las vanguardias, especialmente con el dadaísmo y el surrealismo. (shrink)

At a certain time, the disjunction between philosophy and poetry seemed to denominate the foundational moment which gave a singular life to philosophy, making it unnecessary to refer to anything that was not philosophy. The voice of thought that stopped being relevant to philosophy was the fable..

We revisit the nonrelativistic problem of a bound, charged particle subject to the random zero-point radiation field, with the purpose of revealing the mechanism that takes it from the initially classical description to the final quantum-mechanical one. The combined effect of the zpf and the radiation reaction force results, after a characteristic time lapse, in the loss of the initial conditions and the concomitant irreversible transition of the dynamics to a stationary regime controlled by the field. In this regime, the (...) canonical variables x, p become expressed in terms of the dipolar response functions to a set of field modes. A proper ordering of the response coefficients leads to the matrix representation of quantum mechanics, as was proposed in the early days of the theory, and to the basic commutator x^,p^=iħ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\left[ {\hat{x}},{\hat{p}}\right] =i\hbar $$\end{document}. Further, the connection with the corresponding Fokker–Planck equation valid in the Markov approximation, allows one to obtain the radiative corrections of qed. These results reaffirm the essentially electrodynamic and stochastic nature of the quantum phenomenon, as proposed by stochastic electrodynamics. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

This article provides current Schwartz Values Survey (SVS) data from samples of business managers and professionals across 50 societies that are culturally and socioeconomically diverse. We report the society scores for SVS values dimensions for both individual- and societal-level analyses. At the individual-level, we report on the ten circumplex values sub-dimensions and two sets of values dimensions (collectivism and individualism; openness to change, conservation, self-enhancement, and self-transcendence). At the societal-level, we report on the values dimensions of embeddedness, hierarchy, mastery, affective (...) autonomy, intellectual autonomy, egalitarianism, and harmony. For each society, we report the Cronbach’s α statistics for each values dimension scale to assess their internal consistency (reliability) as well as report interrater agreement (IRA) analyses to assess the acceptability of using aggregated individual level values scores to represent country values. We also examined whether societal development level is related to systematic variation in the measurement and importance of values. Thus, the contributions of our evaluation of the SVS values dimensions are two-fold. First, we identify the SVS dimensions that have cross-culturally internally reliable structures and within-society agreement for business professionals. Second, we report the society cultural values scores developed from the twenty-first century data that can be used as macro-level predictors in multilevel and single-level international business research.

Resumen El artículo sitúa su reflexión en el tema del ecumenismo, relacionándolo con las propuestas de aggiornamento expresadas por el Vaticano II. Hace también alusión al ámbito de las mudanzas en el seno del protestantismo, de las Iglesias ortodoxas e incluso del cristianismo romano. Además alude a los grandes nombres que trazaron la reflexión teológica en el período de crisis que antecedió al evento –hablamos de aspectos que acabaron incidiendo en los debates conciliares. Siguiendo a Gutiérrez, el artículo destaca tres (...) dimensiones relativas a la búsqueda del diálogo de la Iglesia con el mundo contemporáneo: la urgencia de ser actual, la perspectiva ecuménica y la solidaridad con los pobres. Analiza los “caminos equivocados” que fueron adoptados por la Iglesia en lo concerniente a las propuestas ecumênicas del Concilio: el tomar un “execesivo cuidado” en lo que respecta al mundo moderno, las posiciones de intolerância frente a lo diferente, la comprensión reduccionista del ecumenismo. Hace mención a la exigência de construir relaciones que tengan como bases: la gracia y el amor. Por último, propone la tesis de que “no puede existir un sentido del diálogo, un encuentro entre los seres diferentes, sin la libertad”. Palabras-clave : Iglesia. Vaticano II. Ecumenismo. Diálogo inter-religioso.This article focuses its discussion on the theme of ecumenism, in relation to the catholic proposal of aggiornamento expressed by Vatican II. The text refers to the changes within the Protestantism, the Orthodox churches and also within the Roman Christianity. It also mentions the relevant names that marked theological reflection in those times of crisis prior to the Council. Following the author´s thought, the text highlights three dimensions of the dialogue of the Church with the contemporary world: the urgency in getting things update, the ecumenical perspective and the solidarity with the poor. The article evaluates the "wrong path" taken by the Church in relation to the propositions of the ecumenical council: attitudes of intolerance to the different and the reductionist understanding of ecumenism. It also refers to the need to build relationships whose bases are the grace and love. The article finally expresses the following thesis: "there cannot be a sense of dialogue among different beings without freedom." Keywords : Church. Vatican II. Ecumenism. Inter-religious Dialogue. - DOI: 10.5752/P.2175-5841.2011v9n24p1246. (shrink)

Spin is a fundamental and distinctive property of the electron, having far-reaching implications. Yet its purely formal treatment often blurs the physical content and meaning of the spin operator and associated observables. In this work we propose to advance in disclosing the meaning behind the formalism, by first recalling some basic facts about the one-particle spin operator. Consistently informed by and in line with the quantum formalism, we then proceed to analyse in detail the spin projection operator correlation function \=\left\langle (...) \left \left \right\rangle \) for the bipartite singlet state, and show it to be amenable to an unequivocal probabilistic reading. In particular, the calculation of \\) entails a partitioning of the probability space, which is dependent on the directions \.\) The derivation of the CHSH- or other Bell-type inequalities, on the other hand, does not consider such partitioning. This observation puts into question the applicability of Bell-type inequalities to the bipartite singlet spin state. (shrink)

The Gait Deviation Index is a multivariate measure of overall gait pathology based on 15 gait features derived from three-dimensional kinematic data. GDI aims at providing a comprehensive, easy to interpret, and clinically meaningful metric of overall gait function. It has been used as an outcome measure to study gait in several conditions: cerebral palsy, post-stroke hemiparetic gait, Duchenne muscular dystrophy, and Parkinson’s disease, among others. Nevertheless, its use in population with Spinal Cord Injury has not been studied yet. The (...) aim of the present study was to investigate the applicability of the GDI to SCI through the assessment of the relationship of the GDI with the Walking Index for Spinal Cord Injury II. 3D gait kinematics of 34 patients with incomplete SCI was obtained. Besides, 3D gait kinematics of a sample of 50 healthy volunteers was also gathered with Codamotion motion capture system. A total of 302 and 446 strides were collected. GDI was calculated for each stride and grouped for each WISCI II level. HV data were analyzed as an additional set. Normal distribution for each group was assessed with Kolmogorov-Smirnov tests. Afterward, ANOVA tests were performed between each pair of WISCI II levels to identify differences among groups. The results showed that the GDI was normally distributed across all WISCI II levels in both iSCI and HV groups. Furthermore, our results showed an increasing relationship between the GDI values and WISCI II levels in subjects with iSCI, but only discriminative in WISCI II levels 13, 19, and 20. The index successfully distinguished HV group from all the individuals with iSCI. Findings of this study indicated that the GDI is not an appropriate multivariate walking metric to represent the deviation of gait pattern in adult population with iSCI from a normal gait profile when it is compared with the levels of walking impairment described by the WISCI II. Future work should aim at defining and validating an overall gait index derived from 3D kinematic gait variables appropriate for SCI, additionally taking into account other walking ability outcome measures.

A patent is a property granted to any new shape, configuration or arrangement of elements, of any device, tool, instrument, mechanism or other object or part thereof, that allows for a better or different operation, use or manufacture of the object that incorporates it or that provides it with some utility, advantage or technical effect that it did not have before. As a document, a patent really is a title that recognizes the right to exploit the patented invention exclusively, preventing (...) others from making, selling or using it without the consent of the owner. The fact of making a patent is motivated by the fact of promoting creativity, hindering competition in the market as only one person holds the patent, thus protecting the initial investment and fighting against plagiarism. Patents are available to the public for dissemination and general knowledge. It is generally recognized in the specialized literature that patents can be used as an indicator to calculate the results generated by research and development activities, being a very useful indicator to measure various social, economic or technological aspects. For this reason, it is of relevant interest to have tools or systems that allow us to obtain the patents developed in a specific period of time and to carry out analyses of various economic and social factors. These analyses can serve to obtain a social perspective of society’s progress in the technological field, and this is why an analysis of patents is of our interest. This paper proposes a platform specifically designed to obtain knowledge about patents as an indicator of Spanish social, economic or technological aspects. For this purpose, the platform retrieves, analyses and visualizes functionalities that represent data on the landscape of patents obtained from the Spanish Patent and Trademark Office as a particular case of study.

The interdisciplinary analysis of today's drug policy in Brazil, marked by its prohibitionist character, leads to the conclusion that it has frustrated the expectations of all of those who believed that the publication of law 11.343/06 would lead to a different treatment of drug users and traffickers. It is possible to observe some difficulties in the access to the medical use of substances that are considered illicit today, as well as the absence of legal, objective criteria to distinguish users from (...) traffickers. The focus of penal prosecution is not directed toward the great traffickers of drugs, who are still profitting, in a context in which there is no reduction in consumption or commerce. The model of public security has been removed from the principles and guarantees present in the Federal Constitution by identifying black and poor people as potentially criminal. Therefore, starting from the premise that today's drug policy has been managed in irrational fashion and has violated human rights, we propose paths to overcome the problems we have identified.

The paper proposes a financial model suitable for ensuring the economic, financial and social sustainability of this basic protection. We have calculated the estimated cost for the Spanish population in 2010 and have estimated the cost for the following 12 years (three legislatures) under a range of demographic and economic assumptions. The results are then analysed to draw conclusions about the viability and sustainability of this basic social protection floor. A remarkable finding is that it is feasible to obtain greater (...) coverage, but by requiring contributions of the State or other financial resources. (shrink)

O livro “A Técnica e os Riscos da Modernidade” apresenta-se subdividido em cinco capítulos, no primeiro tem-se o título “Liberdade e risco”, onde o autor disserta acerca do desejo e da necessidade humana de transcender as situações cotidianas, isso desde seus primórdios. Nele o autor mostra o quanto a necessidade de ir além das condições imediatas de existência está indissoluvelmente associada ao seu anseio por liberdade. Sendo esta identificada com uma liberdade política, visto que o homem, por sua natureza social, (...) é um ser essencialmente político. Então a questão que aqui se coloca é justamente o que fazer dessa capacidade de ser livre? Ou seja, como bem utilizá-la sem cair nas armadilhas que levam a um mau uso da liberdade? Responder a contento a esse ponto é um dos maiores desafios do homem e um dos que mais lhe provoca aflição, pois, segundo esse entendimento, não se conta com critérios precisos e infalíveis nas avaliações cotidianas, conta-se apenas com incertezas e com a busca por uma conduta moral.

O presente trabalho procura discutir a função-autor a partir de Michel Foucault em suas possíveis contribuições ao campo da Ciência da Informação. Tratando-se de trabalho de caráter qualitativo, a partir de material bibliográfico, realizou-se a leitura da literatura pertinente à temática em textos de Michel Foucault e Paul Otlet, a fim de identificar o tratamento dispensado à figura do autor em ambos, procedendo à realização de um exercício comparativo. Identificou-se em Paul Otlet a presença da atribuição à figura do autor (...) o papel explorado por Michel Foucault em seus textos, correspondendo a um sentido ordenador e a uma espécie de chave de leitura para um conjunto a que se compreende por “obra”. Concluiu-se a necessidade de aprofundar o tratamento dos textos foucaultianos no campo da Ciência da Informação, procurando compreender as condições de possibilidade dos nossos objetos. (shrink)

El presente artículo determina cómo una empresa ética, convertida en escuela de virtudes morales, puede contribuir a mejorar la sociedad. La empresa sólo puede mejorar la sociedad y generar un impacto positivo en la misma desde la ejemplaridad de todas y cada una de sus personas. Se entiende la empresa como una comunidad de personas en la que ha de existir un equilibrio esencial entre lo individual y lo colectivo. Se parte de la premisa de que la empresa es, también, (...) un espacio ético que puede llegar a convertirse en una escuela de valores y virtudes en la que los profesionales desarrollen sus capacidades humanas en interrelación con los demás. Se argumenta la relevancia de la virtud empresarial, desde la perspectiva de la transformación del ethos individual, de los hábitos de las personas que forman la organización. Se considera que la empresa puede llegar a convertirse en una “escuela de valores y virtudes”. La forja del ethos ético y virtuoso de los profesionales es, a su vez, la esencia de la construcción del ethos ético de la empresa que tendrá su correspondiente impacto en el ethos de una buena sociedad. A partir de estas aseveraciones nos hacemos las siguientes preguntas en nuestra investigación: ¿De qué manera puede influir el ethos de la empresa en la configuración de los ethos particulares de los profesionales que forman parte de ella? y ¿cómo puede la empresa contribuir al desarrollo de las virtudes morales de sus personas? Asumiendo estas dos cuestiones como base de la investigación, se argumenta que la empresa puede llegar a ser, a través del trabajo, una ‘escuela’ para el desarrollo de las virtudes morales y, desde ahí, contribuir a la construcción de una sociedad más humana.

La composición polifónica musical nos permite hablar de la emergencia, en el sur y desde el sur que somos, de Voces de la Tierra, que han susurrado, cantado, llorado o gritado el dolor producido por las maneras de habitar humanas construidas en la modernidad cosificadora de la tierra y del mundo de la vida, modernidad mercantil, industrial y global cuya ética se ha reducido a valores absolutamente euro-antropo-racional-centristas, permeados por el valor supremo del capital. En este artículo, emergente de pensadores (...) ambientales latinoamericanos y pensadores-otros que han sospechado radicalmente del edificio de la ética ambiental emergente de la conferencia del Club de Roma o del Informe Burndtland, intentamos desplegar lo ético, como ethos con e larga, que en griego significa casa, y desde este lugar de enunciación, intentamos salirnos del sujeto y del objeto en la variación ética ambiental eurocentrista, y proponer con las voces de la tierra sur, abya yala, diseños del ethos, ligado óntica-relacionalmente con el cuerpo-tierra. Diseñamos, inspirados en Husserl, Heidegger, Deleuze, Guattari, Ángel-Maya, Enrique Leff, Noguera, Echeverri, pensadores-otros y voces de montañas, animales, ríos, y plantas, la vida, territorios de libertad entendida ésta como expansión de los cuerpos en la naturaleza y de paz integral y completa, entendiendo que no puede haber paz, si no amamos ni respetamos la tierra que somos. Esto exige el giro óntico-etico- estético-político de la ética en clave de un Pensamiento Ambiental Sur. (shrink)

El análisis interdisciplinar de la actual política de drogas brasileña, de carácter prohibicionista, lleva a la conclusión que ella ha frustrado las expectativas de aquellos que creían que la promulgación de la Ley 11.343/06 resultaría en un tratamiento distinto a los usuarios y a los traficantes de drogas. Es posible observar una dificultad en el acceso para uso médico a las sustancias que hoy son consideradas ilícitas, la ausencia de criterios legales objetivos para distinguir usuarios de traficantes, y el foco (...) de la persecución penal no está direccionada a los grandes traficantes de drogas, que siguen lucrando, sin que haya una reducción del consumo, ni del comercio. El modelo de seguridad pública está alejado de los principios y garantías previstos en la Constitución Federal, identificando personas pobres y negras como potencialmente criminales. Así, partiendo de la premisa de que la actual política de drogas está siendo regentada de manera irracional, violando los derechos humanos, y desde una perspectiva crítica, son propuestos caminos para la superación de los problemas identificados.

Existe una escisión del hombre con la naturaleza inscrita en los aspectos de la vida; la civilización moderna está en crisis ambiental, de la cultura, de sentido, de la técnica y de la manera en que habita y crea hábitat el hombre.

Se propone entonces un giro en el pensar/habitar hacia la techné, para un reencuentro con el mundo de la vida. (shrink)

El presente artículo aborda las connotaciones y los fundamentos de la paráfrasis cum canere vellem en Serv. Ecl. 6. 3. El análisis del sentido del verbo volo en este contexto y la confrontación del pasaje con Serv. Ecl. 6. 5 revelan que Servio interpreta la frase cum canerem reges et proelia como referencia a un temprano empeño de Virgilio en componer poesía épica, del que pronto desistió. Esta interpretación está condicionada por la idea de que la secuencia cronológica Églogas - (...) Geórgicas - Eneida tiene un correlato jerárquico, idea que se funda en noticias biográficas y en la teoría de la tripertita varietas. This paper focuses on the connotations and grounds of the paraphrase cum canere vellem in Serv. Ecl. 6. 3. The analysis of the sense of verb volo within this context, as well as the confrontation between that passage and Serv. Ecl. 6. 5, show that Servius interprets the clause cum canerem reges et proelia as a reference to Virgil's early endeavor to compose an epic poem, from which he shortly desisted. This interpretation is conditioned by the idea that the chronological sequence Eclogues - Georgics - Aeneid has a hierarchical correlate, an idea which is founded on biographical information and the theory of tripertita varietas.
