Armando Hart Dávalos (1930-2017) fue uno de los intelectuales que reconoció la validez del marxismo cuando el mundo hablaba de su “crisis”. Realizó valoraciones sobre los errores cometidos en la asunción de esta teoría. Además confirmó su utilidad para formar individuos con un pensamiento crítico capaces de cuestionar el mundo contemporáneo. Sus reflexiones son válidas para interpretar y transformar los complejos escenarios sociales que caracterizan la realidad. A pesar de ser distinguido como uno de los marxistas más lúcidos, no abundan (...) los estudios en torno a sus reflexiones. De ahíque este trabajo pretenda revelar las claves metodológicas que se identifican en su pensamiento. Lasque resultan necesarias para la interpretación y la utilización del marxismo en calidad de recursoeducativo para formar al hombre encargado de cambiar su contexto. Los resultados obtenidos señalancomo claves esenciales: el reconocimiento de la esencia antidogmática del marxismo, el electivismo como instrumental teórico-metodológico para pensar y hacer praxis política, el papel determinantede la producción material, sin desdeñar el papel activo del aspecto subjetivo y la incidencia de laespiritualidad en la política, la relación entre cultura y política, y el reconocimiento del carácterrelativo de todo conocimiento asociado a los procesos políticos y sociales.

Se realizó una investigación cualitativa, durante noviembre de 2013 a noviembre de 2015 con el objetivo de mostrar un protocolo de salud como tecnología social para la promoción y prevención de las manifestaciones oftalmológicas en pacientes con VIH/sida. Se utilizaron métodos teóricos y empíricos los cuales permitieron conocer antecedentes del problema a investigar, realizar acciones y caracterizar el fenómeno en estudio. El protocolo constituye una tecnología social, debido a que está compuesto por normas y procedimientos para la conducción de un (...) proceso social no relacionado con la esfera productiva. El diseño de esta tecnología social propicia un adecuado diagnóstico, tratamiento y seguimiento de las enfermedades oculares en pacientes con VIH/sida, sustentado en la teoría del conocimiento. A qualitative investigation was carried out during November 2013 to November 2015 with the objective of developing a protocol as social technology for the promotion and prevention of ophthalmologic manifestations in patients with HIV/AIDS. Theoretical and empirical methods that allowed knowing the antecedents of the problem under investigation, to carry out actions and to characterize the studied phenomenon, were used. The protocol constitutes a social technology, because it is composed by norms and procedures for the conduction of a social process that is not related with the productive area. The design of this social technology favors an adequate diagnosis, treatment and follow-up of eye conditions in patients with HIV/ AIDS, based on the theory of knowledge. (shrink)

Quase que diariamente presenciamos no Brasil o aparecimento de novas alternativas religiosas, assim como uma intensa fragmentação institucional dentro das igrejas protestantes já estabelecidas. Nesse cenário, surgem igrejas autônomas, voltadas a certos públicos específicos, oferecendo produtos simbólicos mais próximos à realidade desses grupos. Enquadra-se entre as voltadas a “tribos urbanas” específicas a “Bola de Neve Church”, oficializada em 1999. Neste artigo, faz-se a análise antropológica da Igreja Evangélica Bola de Neve, situada no bairro Tatuapé, na Zona Leste da cidade de (...) São Paulo, visando a compreender a estrutura de culto, o perfil dos membros e trabalhando o tipo de comunicação que é utilizada, tendo como método de pesquisa o trabalho de campo, leituras específicas sobre o neopentecostalismo no Brasil e entrevistas e análises pessoais dos membros que ali congregam. Também se levanta a possibilidade de essa igreja, bem como outras voltadas a públicos específicos, poder ser interpretada como uma quarta onda do pentecostalismo dentro da teoria das ondas de Paul Freston, onde imperaria a Teologia da Autonomia. Palavras-chave : Bola de neve. Pentecostalismo. Protestantismo. Tribos urbanas.: In Brazil, we witness the emergence of new religious alternatives almost daily, as well as a strong institutional fragmentation within the established Protestant churches. In this scenario, emerge autonomous churches with target specific audiences, offering symbolic products that match the needs of those audiences. For example, churches focused on "urban tribes" such as "Igreja Evangélica Bola de Neve" ("Snowball Church"), incorporated in 1999, on the Tatuapé neighborhood of São Paulo, SP, Brazil. This article presents an anthropological analysis of "Snowball church", seeking to understand the structure of worship, the profile of members, and the kind of communication that is used in there. The research methodology was field work, targeted readings about neopentecostalism in Brazil, and interviews with church members. It also raises the possibility of this church and others focused on “urban tribes” be interpreted as a fourth wave of pentecostalism in Paul Freston`s wave theory, where a Theology of Autonomy prevails. Keywords: Snowball. Pentecostalism. Protestantism. Urban tribes. (shrink)

BackgroundAlthough gait patterns disturbances are known to be related to cognitive decline, there is no consensus on the possibility of predicting one from the other. It is necessary to find the optimal gait features, experimental protocols, and computational algorithms to achieve this purpose.PurposesTo assess the efficacy of the Stable Sparse Classifiers procedure for discriminating young and healthy older adults, as well as healthy and cognitively impaired elderly groups from their gait patterns. To identify the walking tasks or combinations of tasks (...) and specific spatio-temporal gait features that allow the best prediction with SSC.MethodsA sample of 125 participants was studied. They underwent assessment with five neuropsychological tests that explore different cognitive domains. A summarized cognitive index, based on the Mahalanobis distance from normative data, was calculated. The sample was divided into three groups using k-means clustering of MDCog in addition to Age. The participants executed four walking tasks and their gait patterns, measured with a body-fixed Inertial Measurement Unit, were used to calculate 16 STGF and dual-task costs. SSC was then employed to predict which group the participants belonged to. The classification's performance was assessed using the area under the receiver operating curves and the stable biomarkers were identified.ResultsThe discrimination HE vs. MCI-E revealed that the combination of the easy dual-task and the fast walking task had the best prediction performance. The features related to gait variability and to the amplitude of vertical acceleration had the largest predictive power. SSC prediction accuracy was better than the accuracies obtained with linear discriminant analysis and support vector machine classifiers.ConclusionsThe study corroborated that the changes in gait patterns can be used to discriminate between young and healthy older adults and more importantly between healthy and cognitively impaired adults. A subset of gait tasks and STGF optimal for achieving this goal with SSC were identified, with the latter method superior to other classification techniques. (shrink)
