Applying SAXS to study the structuring of Fe3O4 magnetic nanoparticles in colloidal suspensions
Authors: Cordoba Jenny Mera , Coral-Coral Diego Fernando
Published: July 2019

In this work, Small Angle X-ray Scattering (SAXS) patterns, obtained from two different aqueous colloidal suspensions of magnetite nanoparticles electrostatically stabilized with citric acid, were fitted using three different mathematical models in order to describe the particle size distribution and aggregation state. The colloidal suspensions differ in the mean particle size (4.5±1.0 nm and 5.5±1.1 nm) and the aqueous stabilization, allowing control of the strength of the interaction strength between particles. The models used for SAXS analysis, reveal that the particles are almost spherical with a broad size distribution, and that particles in each suspension are aggregated and are subject to an attractive interaction potential, typical for magnetic nanoparticles. For the better-stabilized sample, ramified chain-like aggregates were found, and for the less-stabilized sample, a more compact structure was determined. The size distribution obtained by applying SAXS mathematical models are in agreement with the size distribution determined using Transmission Electronic Microscopy(TEM)

Los crudos pesados de pavimentación (CPP) constituyen asfaltos líquidos naturales que pueden ser empleados en soluciones de pavimentación no convencionales para vías de tránsito bajo y medio por su menor costo en comparación con el de cementos asfálticos convencionales (i.e., producidos mediante refinación de crudos de petróleo). A pesar de su potencial, la caracterización y el uso de CPP en pavimentación vial son aún limitados. Este estudio evalúa la calidad de la adhesión y las propiedades reológicas de asfaltos residuales (AR), no modificados y nano-modificados, obtenidos de CPP. Los resultados sugieren que los AR ofrecen menor rigidez y desarrollan interfases asfalto-agregado con menor calidad de adhesión que las generadas por el asfalto convencional de control. En general, el nano-modificador redujo la rigidez de los AR, y aunque mejoró la adhesión en seco, no redujo la susceptibilidad al daño por humedad en las interfases asfalto-agregado. Se sugiere investigación futura que valide los resultados a través de la evaluación de mezclas asfálticas.

Predicting precipitation rate and rainfall attenuation are key aspects in planning and dimensioning of wireless communications systems operating at frequencies above 10 GHz, such as satellite communication systems at Ku and Ka bands. In this paper, contour maps of rainfall rate and rain attenuation are developed for the first time in Venezuela, based on 1-min rain rate statistics obtained from measurements carried out in Venezuela over at least 30 years period with a higher integration time and using Rice-Holmberg model, refined Moupfouma-Martin model and Recommendation ITU-R P.837-7, for rain rate estimation and Recommendation ITU-R P.618-13, Ramachandran-Kumar model, Yeo-Lee-Ong model and Rakshit-Adhikari-Maitra model, for rain attenuation prediction in “Simon Bolivar” satellite links in Venezuela. The overall results of both types of maps represent a useful tool for preliminary planning of those links in the country, specifically, in Ku and Ka bands

Published: July 2019

The results of characterizing the alumina ball size distribution in two mills of a crushing and grinding plant are shown. The mills were unloaded and the ball charge was screened in order to establish the ball size distribution. For both mills, the balls retained during the unloading were compared to the balls retained at the beginning of the process, and additionally, they were compared to the results obtained by the Swebrec adjusted distribution model. In both cases, the experimental data have had a good fit with this model. This practice is important in order to establish the best ball charge at the beginning of the operation and the ball recharge in the steady state.

Authors: Ñústez Castaño Stephanie Alexa , Villamizar Castro Duvan Oswaldo , Vargas Solano Edgar Mauricio
Published: July 2019

In this study, the catalytic activity of dolomite was evaluated for the transesterification of Colombian RBD palm oil with methanol, carried out in a batch reactor at 333,15K and 600rpm. The activated dolomites (calcined at 1073.15K for 2h) were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), Hammett indicators method, and quantification of the surface area, average pore size and average pore volume BET. The influence of reaction variables such as catalyst amount (%wt /wt) and methanol / palm oil molar ratio (mole/mole) was investigated. Under the suitable reaction conditions, the amount of calcined dolomite equal to 4% (wt /wt) based on the weight of oil, the methanol-oil molar ratio equal to 9:1, and the reaction time = 1h, the methyl ester content of 82.67% of fatty acid methyl esters (FAME) can be achieved.

Authors: Prieto Garzón Johanna Beatríz , Lima-Machado Álvaro Muriel , Scheer-Hainosz Fabiano
Published: July 2019

This study consists in the detection of changes in buildings with LIDAR technology, for which, changes in buildings are identified,classified and quantified of two study areas mapped by LIDAR sensors, using the direct comparison of multi-temporal points clouds obtained from mapping. The process begins with the correction of errors in point cloud records after two detection methods are applied:the first one is called indirect method due to the transformation of the raster data; the second one is called direct method, of vector type.When quantifying the detected buildings, an important approximation was obtained from both methods concerning the locations of these buildings and, when estimating height and area, the direct method presented higher accuracy. In conclusion, both methods are efficient tools for observation of the real estate dynamics through different time intervals.

Published: July 2019

Because of anthropogenic impacts on the trophic state of Tecocomulco´s lagoon in Hidalgo, Mexico, the quantities of nitrogen, phosphorus, and other biologically useful nutrients are being increased in spite of they are the primary determinants of a body of water's trophic state index. Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water bodies, so increased concentrations tend to result in increased plant growth, followed by corollary increases in subsequent trophic levels. Consequently, a body of water's trophicindex may sometimes be used to make a rough estimate of its biological condition. Actually, in order to protect the environment, a new level of planning and execution of development projects have been originated by life cycle assessment, environmental impact researchesand evaluating economic financial researches due to the understanding that, environment will be irreversible damaged by any kind ofproject.
Support vector machines applied to fast determination of the geographical coordinates of earthquakes, The case of El Rosal seismological station, Bogotá Colombia
Authors: Ochoa Gutierrez Luis Hernán , Niño Vasquez Luis Fernando , Vargas Jimenez Carlos Alberto
Published: July 2019

AbstractThe objective of this research was to determine seismic events latitude and longitude using support vector machines (SVMs) and seismic records from “El Rosal” station, which is located 40 kilometers northwest of Bogotá, Colombia. A total of 504 SVMs models were tested to determine latitude and 504 models for longitude, with various combinations of complexity factor and kernel function exponent, applied to earthquakes of 2, 2.5, 3 and 3.5 ML in time windows of 15 , 10 and 5 seconds. The best results showed errors of 40 kilometers for latitude and 30 kilometers for longitude, with respect to the place where the earthquakes were generated. These outcomes might be improved by applying additional descriptors during SVMs training stages, such descriptors can be related to Fourier frequency spectra, predominant period and wavelet transform coefficients.

Published: July 2019

Within urban system, there are relationships between the constituent elements, which function through the consumption of matter and Energy imported from the environment. This study reviews from the systems theory approach the decisions focused on pressing the environment through the El Zapotillo dam in the second most important metropolis in Mexico. The Entropy-Homeostasis-Negentropy model is used. The results obtained show that the decisions for the water supply of the metropolis are limited to short-term negentropies, both in the functioning and in the configuration of the surrounding systems. In this way, it becomes urgent to specify systemic actions that promote the Integrated Management of Water Resources (IWRM).
Point cloud saliency detection via local sparse coding
Authors: Leal Narvaez Esmeide Alberto , Sanchez Torres German , Branch Bedoya John William
Published: July 2019

The human visual system (HVS) can process large quantities of visual information instantly. Visual saliency perception is the process of locating and identifying regions with a high degree of saliency from a visual standpoint. Mesh saliency detection has been studied extensively in recent years, but few studies have focused on 3D point cloud saliency detection. The estimation of visual saliency is important for computer graphics tasks such as simplification, segmentation, shape matching and resizing. In this paper, we present a method for the direct detection of saliency on unorganized point clouds. First, our method computes a set of overlapping neighborhoods and estimates adescriptor vector for each point inside it. Then, the descriptor vectors are used as a natural dictionary in order to apply a sparse coding process. Finally, we estimate a saliency map of the point neighborhoods based on the Minimum Description Length (MDL) principle.Experiment results show that the proposed method achieves similar results to those from the literature review and in some cases even improves on them. It captures the geometry of the point clouds without using any topological information and achieves an acceptable performance. The effectiveness and robustness of our approach are shown by comparing it to previous studies in the literature review.
Fingerprint analysis of FTIR spectra of polymers containing vinyl acetate
Authors: Ramírez-Hernández Aurelio , Aguilar-Flores Celia , Aparicio-Saguilán Alejandro
Published: July 2019

The analysis of materials using Fourier transform infrared (FTIR) spectroscopy has a unique area called the fingerprint region for each compound. However, this area is almost never discussed because of its complexity due to the large number of signals that appear in it. In this work, the fingerprint region analysis of the ethylene–vinyl acetate copolymer (EVA) with different percentages of vinyl acetate (VA) (18%, 28%, 40%) was performed. In comparison with other instrumental techniques, the crystallinity and structural arrangement of the EVA copolymers were determined simply and economically. The crystallinities for EVA18, EVA28 and EVA40 were 24.39%, 6.95% and1.03%, respectively. In terms of structural ordering, the number of linear chains of EVA copolymer decreases as the concentration of VA increases, which favors the reduction of degrees of freedom and the formation of hydrogen bonds.

Authors: Supelano Gracía Iván , Aperador Pacheco William Arnulfo , Parra Vargas Carlos , Sarmiento Santos Armando
Published: July 2019

We report the synthesis of CaMn0.9Mo0.1O3 manganite by glow discharge (GD) plasma treatment under Argon-Air atmosphere. The morphological, structural and magnetic properties were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and magnetization measures. The results from these measures reveal that the properties of GD synthesized manganite are similar to that exhibited by CaMn0.9Mo0.1O3 produced by conventional resistive furnace. The Rietveld analysis of XRD patterns performed at room temperature show that the samples crystallize in orthorhombic structure of Pnma (62) space group. The magnetization curves as a functionof temperature show two inflection points related to paramagnetic-antiferromagnetic and structural transition. The GD treatment produces a compound with similar properties, reducing the time and energy consumption in comparison with conventional synthesis route by using resistive furnace.
Revisión de la gestión ambiental sobre el territorio y cambio climático en el departamento del Quindío, Colombia
Authors: Ruiz-C. Raquel I. , Román-Valencia César , Gonzalez-E. Carlos H.
Published: July 2019

En este trabajo se analizan las bases de la gestión ambiental frente al cambio climático en los 12 municipios del departamento de Quindío, Colombia. Se efectúo una revisión documental y análisis de datos y observaciones obtenidos sobre la gestión ambiental en el marco de cambio y análisis climático en la planificación territorial y planes de desarrollo sobre dos vigencias administrativas (2012–2015 y 2016-2019). Se encontró que las directrices para el progreso no han sido implementadas efectivamente en algunas administraciones o es incompleta la inclusión del tema ambiental y climático, en el ordenamiento territorial de las respectivas administraciones municipales, en el sentido de establecer medidas de protección y prevención ambiental efectivas. Lo anterior se debe al modelo económico imperante y/o en casos, por ejemplo, a los conflictos de interés de las personas que realizan y proyectan las herramientas en el contexto de la planificación y desarrollo sustentable. Por tanto, enfrentar desafíos de gestión ambiental a la luz de los requisitos del cambio climático a nivel de los gobiernos locales requiere una comprensión de las complejas dimensiones del territorio y la coordinación con la identidad del mismo, más allá de un modelo desarrollo impuesto.

Published: July 2019

El objetivo del presente trabajo fue evaluar el efecto de la deshidratación de los lodos en lecho de secado sobre las características fisicoquímicas de estos subproductos y la actividad biológica de los microorganismos. Se determinó que después de cinco meses de secado disminuyó la concentración de carbono orgánico, los metales pesados se mantuvieron por debajo del límite permisible y el nitrógeno y fósforo total se mantuvieron constantes. Se evidenció disminución de los aerobios mesófilos, hongos y amilolíticos de siete, seis y una unidad logarítmica de UFC/g respectivamente. La presencia de microorganismos funcionales celulolíticos y solubilizadores de fosfato fue <10 UFC/g. Por otro lado, el 3 % (n=8040) de las cepas evaluadas, fueron productoras de PHA en por lo menos una de las fuentes de carbono evaluadas (sacarosa o glucosa). Los resultados demuestran que el tratamiento de deshidratación en lecho de secado permitió conservar las características fisicoquímicas de los lodos, no obstante, disminuyó la actividad biológica de los microrganismos aerobios mesófilos, amilolíticos y hongos, celulolíticos, solubilizadores de fosfato.
VISION WELTREPUBLIK – DEMOKRATIE IM ZEITALTER DER GLOBALISIRUNG
Authors: Höffe Otfried
Published: July 2019

A teoria da justiça política, segundo Hóffe, fundamentada na justiça comutativa, sustenta que a fundamentação das reivindicações normativas da sociedade na comunidade discursiva, como o fazem Apel e Habermas em sua ética do discurso, é apenas uma fundamentação derivada, pois a comunidade discursiva necessariamente pressupõe direitos humanos. Por sua vez, a ética do discurso argumenta que os direitos humanos só podem ser legitimados através do discurso. Este artigo mostra que o pressuposto normativo tanto para a comunidade discursiva quanto para o princípio da justiça comutativa é que todos os seres humanos são autorizados a uma partilha do mundo. Somente através desta premissa de uma justiça distributiva pode haver parceiros capazes de exercer reciprocidade e participantes do discurso que também tenham algo sobre o que tenham de decidir juntos.

Reflexões acerca da articulação entre o trabalho e a educação profissional e tecnológica no Brasil
Authors: Costa Dirno Vilanova da
Published: July 2019

A Educação Profissional e Tecnológica relaciona-se diretamente ao trabalho. Este, enquanto produtor do ser humano, torna-se a categoria central do materialismo histórico- dialético defendido por Karl Marx. O objetivo deste artigo, que é parte de pesquisa de mestrado em andamento na Universidade Federal do Piauí, é refletir sobre a formação via EPT, constituída sob os pressupostos de uma formação tecnicista ou de formação integral do estudante/trabalhador. Para entender esse processo formativo, parte-se do questionamento: qual a relação entre as perspectivas de formação e concepção de trabalho tem mediado à formação de trabalhadores no Brasil? Propõe-se explicar a problemática apresentada pelas categorias trabalho e educação que estão ancoradas concepção da pedagogia histórico-crítica e nos pressupostos do materialismo histórico dialético. Para tanto, essa análise ancora-se, sobretudo, nos trabalhos de Marx; Saviani e Duarte; Frigotto, Ciavatta e Ramos; Manacorda; Santos; entre outros autores que discutem a temática em epígrafe, além de legislações e documentos oficiais, a exemplo da Lei 9394/1996 e do Decreto 5154/2004. Ao final, constatou-se que embora a formação via Educação Profissional e Tecnológica no Brasil tenha alcançado saltos qualitativos durante o percurso histórico, ainda prevalece uma formação técnica que necessita avançar no âmbito da formação crítica e emancipatória.
Intersectional insights from an MDMA-assisted psychotherapy training trial: An open letter to racial/ethnic and sexual/gender minorities
Authors: Ching Terence H. W.
Published: July 2019

The road to the current psychedelic renaissance in research on ±3,4-methylenedioxymethamphetamine (MDMA) – the active ingredient of the drug Ecstasy – for addressing treatment-resistant post-traumatic stress disorder has been fraught with political and academic bias, as well as cultural stigma among underserved populations, all of which serve as barriers to minority inclusion and participation. In this open letter to ethnic/racial and sexual/gender minorities, the author details intersectional insights from his own experience being administered MDMA legally as part of a therapist training trial for MDMA-assisted psychotherapy, in hopes of radically destigmatizing this treatment approach for marginalized populations. Themes covered include: set and setting; cultural pride; LGBTQIA+ pride; acceptance of intersectionality; and patience, perspective, and strength in retrospection. This letter concludes by tasking current investigators of MDMA-assisted psychotherapy to emphasize issues of intersecting identities (e.g., in terms of race, ethnicity, sexual orientation, and gender identity) in their research agenda, attempt to improve minority participation in a culturally attuned manner, as well as increase minority stakeholdership in this field.

Value of fruit firmness decreased after 4 days of storage. The use of packaging in the form of wrap plastic and paper were not better than without packaging (control) to the firmness of the crystal guava fruit.
Mapping Awareness of Halal Cosmetics Brands in the Teenagers Segment of Bandung City
Authors: Muhsin Muhsin
Published: July 2019

There are many factors that can explain why the consumer market for halal products is now growing fast, among others, because the profile of the younger generation of Islam is now more religious thanks to the rapid flow of information, awareness, knowledge and concern for halal consumption. One component of brand strength is brand awareness, which is how well consumers know or know about a brand. Therefore, brand awareness is a key determinant of building brand equity. When products are in the early stages of growth, such as halal cosmetics, which are new players in the cosmetics business, brand awareness is important to encourage this growth. The first research problem departed from the central phenomenon of how teenagers actually aware of halal cosmetics in the city of Bandung, and which halal cosmetic brands are best known? Associated with the issue of brand strength, then more specifically the problem of this research is how strong are teenagers aware of some halal cosmetic brands that are circulating in the city of Bandung, high, medium or low? Then is this brand awareness related to consumer demographic factors? Then is this brand awareness related to loyalty to halal cosmetic brands? The results showed that adolescents in the city of Bandung who require to use cosmetics labeled halal because they are aware of religious values, one of which as a form of Islamic law is included in rational instrumental actions. Then interpret cosmetics labeled halal as a form of carrying out Islamic law because it is protected from material that is haram and will not affect worship. Teenagers in Bandung City who are not based on using cosmetics labeled halal because they prefer cosmetics based on their needs and price and quality are included in instrumental rational actions. Then interpret halal labeled cosmetics as cosmetics that are safe for the skin because they do not cause irritation, cosmetics that are protected from prohibited ingredients, cosmetics that have no difference with other cosmetics.
Incorporating spirit
Authors: Stone Emma Francis
Published: July 2019

The barrier that separates the spiritual and earthly worlds is paper thin in Brazil. The infusion of the spiritual into the secular manifests in diverse ways, but is perhaps best represented by the prevalence of ritual possession in the region, where the spiritual and material merge. This paper will focus on the phenomenon of ritual possession within Umbanda, an eclectic Afro-Brazilian spiritual tradition. It will first explore existing sociological and socio-functionalist analyses or ritual possession in Brazil, and then argue that there is a need for an analysis that makes sense of possession from an embodied perspective. Drawing on the testimonies of mediums from two Umbanda centers in Rio de Janeiro (the Casa da Caridade Caboclo Peri) and Sao Paulo (Templo Guaracy) in Brazil, the article will investigate the appeal of ritual possession as a spiritual practice located and experienced in the body.
Ritual, rejuvenation practices, and the experience of aging in early Chinese religion
Authors: Tavor Ori
Published: July 2019

Scientific advances in the field of biomedicine have fundamentally changed the ways in which we think about our bodies. Disease, aging, and even death, are no longer seen as inevitable realities but as obstacles that can be controlled, and in some cases even reversed, by technological means. The current discourse, however, can be enriched by an investigation of the various ways in which the aging process was perceived and explained throughout human history. In this article, I argue that in early China, the experience of aging and the challenges and anxieties it produced played a constitutive role in the shaping of religious culture. Drawing on a variety of medical, philosophical, and liturgical sources, I outline two models of aging: one that presented aging, and especially the loss of virility, as an undesirable but solvable condition that can be reversed with the aid of various rejuvenation techniques, and a more socially conscious model that depicted aging as a process of gradual social ascension, a natural but fundamentally unalterable condition that should be accepted, marked, and even celebrated through ritual. I conclude by demonstrating the legacy and lasting influence of these models on two of the most fundamental tenets of Chinese religion: the pursuit of longevity and the ideal of filial piety.

Graham Harvey’s reconceptualisation of religion emphasises the relational world of indigenous peoples. His suggestion that religion revolves around negotiating with ‘our neighbours’ is particularly relevant to Native American ritual processes insofar as he extends ‘neighbours’ to other-species persons. Further, by emphasising ‘lived religion’, Harvey turns our attention to the significance of embodied religion as it expresses itself in ceremonial performances. Harvey’s approach is enriched by Ronald L. Grimes’ notion of the way in which indigenous rituals take us into the deep world of other-species communities through a gift exchange economy that promotes the wellbeing of everyone in the neighbourhood.

The present discussion demonstrates the applicability of both Harvey’s and Grimes’ approaches to indigenous religious ritual processes by focusing on James R. Walker’s account of Oglala Sun Dancing. Walker constructs a fourstage ritual process from information he gathered while working as a physician on the Pine Ridge Reservation from 1896 to 1914. The entire process, from the declaration of the first candidates who announce their intention to make bodily sacrifices to the culmination of the ritual process in the last four days where the flesh sacrifices are made many months later, centres on re-establishing and promoting harmonious relations among the Oglala and between the Oglala and their other-species neighbours within the Sacred Hoop. The indigenous methodological approach interprets the process through Oglala cosmological and ontological categories and establishes the significance of Harvey’s approach to religion and Grimes’ approach to ritual in understanding embodied and lived religion.

Resumo        O adoecimento por câncer na adolescência apresenta especificidades do ponto de vista biopsicossocial, o que coloca desafios à equipe na prestação de uma assistência de qualidade. Diante disso, este estudo teve como objetivo  compreender a vivência do cuidado ao adolescente com câncer, na perspectiva da equipe multiprofissional de um Serviço de Onco-Hematologia adulto, de um hospital geral do sul do país. Para tal, foram realizadas entrevistas semiestruturadas com nove  profissionais que compõem a equipe multiprofissional. A análise foi qualitativa, através do método de análise de conteúdo. Os dados foram organizados em quatro categorias: especificidades do cuidado ao adolescente com câncer, sentimentos mobilizados nos profissionais de saúde,  estratégias de enfrentamento utilizadas pela equipe e  desafios na assistência. A partir dos resultados, identificou-se que o cuidado ao adolescente oncológico tem impacto emocional significativo nos profissionais de saúde, exigindo investimento técnico e emocional por parte dos mesmos.

Authors: Santos Caicedo Doris Adriana , Baquero Castellanos Silvia , Beltrán Muete Mireya
Published: July 2019

A partir de la reseña de un estudio de caso realizado en 2005 sobre las adaptaciones pedagógicas utilizadas por un grupo de docentes a cargo del único estudiante sordo admitido en 2003 en la Universidad Nacional de Colombia, se presentan algunas reflexiones para la formulación de una política curricular institucional orientada hacia la integración académica de estudiantes sordos en este contexto educativo. Algunas de las consideraciones centrales conciernen a la necesidad de utilizar más recursos tecnológicos visuales de la información y de la comunicación, así como de diseñar y poner en marcha un programa institucional de acompañamiento permanente a los estudiantes sordos admitidos y a sus docentes con miras a garantizar un desarrollo adecuado del proceso de formación involucrado.

Authors: Rodriguez de Salazar Nahir , Garcia Rios Diana Patricia , Jutinico Fernández Maria del Socorro
Published: July 2019

Este documento aporta elementos para la comprensión de un proyecto institucional, de educación superior inclusiva, de la Universidad Pedagógica Nacional, y su propósito gira en torno a la formación de licenciados sordos para atender las necesidades educativas de la población sorda colombiana. Manos y Pensamiento: Inclusión de estudiantes sordos a la vida universitaria , como se le denomina, es una propuesta en desarrollo en la que han estado presentes, además de la comunidad sorda, teóricos que nutren y proporcionan fundamentos para el debate sobre la constitución de sujeto y subjetividad del educando sordo, e investigadores en el tema de la atención a la diversidad, en escenarios de educación superior, que brindan valiosos elementos para la estructuración pedagógica del proyecto y el desarrollo de las distintas acciones que demanda. Ha sido pensado como un proyecto de gran complejidad, por los múltiples factores que debe abordar. No se trata de un simple proceso de vinculación universitaria, sino de un encuentro de culturas, lenguajes, mundos, formas de sentir, pensar e imaginar. Es el ejercicio permanente de la convivencia, bajo un mismo espacio y tiempo, de educandos en condiciones distintas que apenas empiezan a descubrirse y valorar lo que significan en un mundo social. Es, por tanto, una oportunidad de transformación social y ciudadana. El artículo, en tono propositivo, presenta los principales aspectos relacionados con el origen del proyecto y describe los referentes teóricos y legales que lo sustentan. Así mismo, narra el proceso seguido en la Universidad Pedagógica para la implementación de esta experiencia de inclusión educativa.
Articulaciones educativas para la inclusión de la diversidad
Authors: Munevar Dora Inés
Published: July 2019

En el artículo se sostiene que las transformaciones educativas exigen compromisos individuales y acciones colectivas; también que en el marco de la ciudadanía y la justicia social se articula el debate sobre la inclusión en franca relación con las exclusiones. Este debate ha dado origen a la inclusión en la educación como un derecho que interroga a las complejas relaciones entre escuela e inclusión, como la base del ejercicio material de los derechos económicos, sociales y culturales, DESC, y como medio para hacer visibles los matices de la diversidad humana y escuchar la polifonía de sus voces. Por eso mismo, en los escenarios escolares se introduce el proceso de advocacy  o abogacía como un mecanismo de exigibilidad política y jurídica de la educación inclusiva en clave de derechos. Esta alternativa exige pensar las articulaciones educativas en una institución resistente a las transformaciones.

A participação social na vigilância de medicamentos
Authors: Soares Julino Rodrigues , Oliveira Vanessa Elias de
Published: July 2019

Objective: to analyze the contribution of patients in drug surveillance, considering some stages of development of these technologies and the interest of public health. Methodology: a bibliographic and documentary analysis was performed on patients' contributions and mechanisms of social participation. Results: we identified consolidated initiatives and results that support the importance of patients in drug surveillance in various segments. However, participation is limited due to the low scientific literacy and ineffectiveness of some social participation mechanisms. Conclusion: patient representative organizations can contribute more effectively to social participation initiatives in drug surveillance, as reported in international experiences. In addition, it is essential that regulatory agencies seek to improve participation mechanisms and the use of methods to collect social contributions, as well as to systematize patients' experiences.
