Authors: Lerma García Liliana , Rivas Porras Dulce , Adame Gallegos Jaime Raúl , Ledezma Millán Fernando , López De La Torre Hector Alejandro , Ortiz Palomino César Eduardo
Published: December 2020

Con su abaratamiento, creciente popularización y diversidad de herramientas para su desarrollo y uso, las llamadas tecnologías inmersivas han demostrado su eficacia y potencial en el ámbito del aprendizaje mediado por tecnología. Existen, sin embargo, insuficientes esfuerzos encaminados a entender la manera en que los estudiantes se aproximan, perciben y evalúan desde el análisis de la experiencia de usuario esta categoría de aplicaciones tecnológicas. El presente estudio, realizado por el Laboratorio de Innovación en Experiencias de Aprendizaje y la Facultad de Ciencias Químicas de la Universidad Autónoma de Chihuahua, tiene por objetivo obtener elementos que ofrezcan nuevos indicios sobre las estrategias a seguir en la generación y aplicación de experiencias de aprendizaje mediadas por Realidad Virtual Inmersiva (rvi), en el ámbito de la educación superior, específicamente en el área de las ciencias de la vida. Para el presente estudio, integraron la muestra 32 estudiantes de nivel ingeniería, inscritos en el curso regular de patología en el programa «Químico Biólogo Parasitólogo», impartido en la Facultad de Ciencias Químicas de la Universidad Autónoma de Chihuahua. Se evaluaron factores relativos a la usabilidad y la experiencia del usuario; incluyendo atractividad, claridad, eficiencia, manejabilidad, estimulación e innovación. Para ello, se recurrió a la aplicación de un Cuestionario de Experiencia de Usuario (ceu), compuesto por 26 reactivos, divididos en las categorías mencionadas. El análisis de los resultados arroja un nivel positivo en la valoración de la experiencia de usuario y presenta elementos adicionales, potencialmente útiles para instituciones educativas que evalúan el uso de rvi como entorno de soporte para sus procesos instruccionales.
CLIL Teacher Training: Lacks and Suggestions from a Systematic Literature Review
Authors: Porcedda Maria Elisabetta , González-Martínez Juan
Published: December 2020

This systematic literature review aims firstly at highlighting lacks and suggestions and/or good practices in clil teacher training, analysing and crossing the results, obtained from academic repositories; then at contributing to reach an optimal level of training for clil teachers, highlighting good practices as suggestions to fill the lacks. The 39 documents, which describe studies and mostly practices from almost all the European countries, have been obtained by Scopus, Educational Resources Information Centre (eric), ScienceDirect and partially Google Scholar, through the descriptor «clil teacher training» and a post-reading selection of the articles. Their qualitative data provided an exhaustive picture of the comprehensiveness of results, required by the method of systematic reviews. clil results to be a complex approach, involving many aspects which need to be considered. It is primarily perceived to be as engaging for students as demanding for teachers, due to its being learner-centred, with a large use of icts and online tools, as its implementation through a new pedagogy and modern teaching strategies, such as flipped-classroom and task-based. This is the theoretical starting point of the different actions and policies set up in the countries to train teachers for clil. But the results of this review, which draw the characteristics to take into account to train future clil teachers, underline the need of pre-service teacher training at University, hitherto generally disregarded in favour of in-service preparation. Concerning this latter, from the stakeholders in particular it is suggested continued update in clil method and research; further collaboration with colleagues, especially telecollaboration, which can be the answer to the need of clil update and to share good practices in authentic online communities; last but not least, further pedagogical preparation and management of icts, because clil aims to change the traditional schooling.
Modelos de inteligencia y altas capacidades: una revisión descriptiva y comparativa
Authors: Robres Alberto Quílez , Lozano Blasco Raquel
Published: December 2020

La relación entre la inteligencia y el rendimiento académico ha dado paso a diferentes teorías y modelos durante los últimos cuarenta años. Entre las elaboradas durante el siglo xx destacan la Teoría de los Tres Anillos de Renzulli (1978), basada en la sobredotación; la de las Inteligencias Múltiples de Gardner (1983), que propone el desarrollo de diferentes habilidades; la Teoría Triárquica de Sternberg (1985), que presenta un carácter cognitivo, y el modelo Sea Star de Tannenbaum (1986), con un punto de vista sociocultural. Ya en el siglo xxi aparece el megamodelo de Desarrollo del Talento de Subotnik, Olszewski-Kubilius y Worrell (2012) y el modelo Tripartito de la Alta Capacidad de Pfeiffer (2015). Con el desarrollo de estos modelos, al concepto de inteligencia se añaden los de talento, superdotación, habilidades y capacidades. Este artículo realiza una revisión y comparación de los modelos más representativos vinculados a las altas capacidades por considerar que son imprescindibles a la hora de elaborar propuestas didácticas para el desarrollo de un aula de altas capacidades. Todos ellos destacan por la búsqueda de la atención a la diversidad y a la inclusión educativa de los más capaces, y también por la elaboración de propuestas que favorezcan su pleno desarrollo.

Educação do Campo e Formação de Educadores na Perspectiva do Ensino Desenvolvimental: por uma Educação Crítica e Emancipatória aos Povos do Campo
Authors: Magalhães Solange Martins Oliveira , Moura Sílvia Adriane Tavares de
Published: December 2020

O artigo apresenta um estudo teórico pautado na perspectiva do Ensino Desenvolvimental e na Base Histórico-Cultural, objetivando identificar princípios epistemológicos que sustentem uma concepção de Educação do Campo, bem como de formação de seus professores, que possibilitem a materialização de uma educação alternativa, crítica e emancipatória aos povos do campo. Sustentam-se três focos de discussão e reflexão: a) marco histórico da Educação do Campo, influências neoliberais; b) marcos legais da formação de educadores do campo frente ao agravamento da influência neoliberal em tempo de Pandemia Covid-19; c) a contribuição da perspectiva do Ensino Desenvolvimental para a proposição de uma concepção de Educação do Campo, pública, gratuita e de qualidade social. Os princípios epistemológicos identificados, fortalecem a Obutchenie como processo responsável por um sistema de organização e métodos que asseguram a apropriação da experiência socialmente formada, promovendo mudanças qualitativas no desenvolvimento mental dos sujeitos, logo nas possibilidades de emancipação e transformação social.
Sobre o sentido na obra de Leontiev: notas a partir de sua biografia
Authors: Silva Flávia Gonçalves da
Published: December 2020

O objetivo deste texto é apresentar os principais aspectos biográficos de Leontiev, tendo como referência sua obra, e identificar algumas lacunas, apontadas tanto por seus críticos como por seus continuadores, especificamente nos estudos sobre o sentido. Foram utilizadas obras de Leontiev e textos de alguns de seus continuadores e estudiosos. O sentido, como conteúdo da consciência, revela a dimensão afetivo-emocional do motivo da atividade para o indivíduo, possibilitando também a (re)criação da realidade externa no psiquismo, formando o reflexo psíquico. A consciência é construída na atividade do indivíduo é, para Leontiev, a categoria de análise que tem prioridade ontológica, seguindo a tradição marxista que aponta a centralidade do trabalho na formação humana. Apesar de ser um conteúdo da consciência, o sentido pessoal pode ser oculto, no entanto, Leontiev não fez apontamentos sobre quais implicações estes poderiam promover no psiquismo. Alguns de seus continuadores propuseram que os motivos ocultos podem possibilitar novas formações psíquicas, constituindo as formações da personalidade baseadas no sentido pessoal. Entende-se que tais apontamentos possibilitam melhor compreensão sobre o desenvolvimento e aprendizagem (bem como de outros processos) ao mesmo tempo em que pode sinalizar novos rumos para os estudos do sentido a partir da obra do autor. Esse avanço nos aspectos teóricos de Leontiev ocorre quando sua obra é entendida como inacabada e inserida numa teoria psicológica que foi construída por vários autores, que, apesar das diferenças, tiveram como projeto a construção de uma psicologia que entendesse o homem em sua totalidade.
Lo legible irónico: retracción y supervivencia de la garantía científica en Cataratas de Hernán Vanoli
Authors: García Nicolás
Published: December 2020

La distopía no deja de expandirse en el panorama literario argentino actual y es un problema para la crítica distinguir las invariantes genéricas de aquello que se presenta de por sí alterado. La descripción de un mundo ligeramente futuro, tomado por grandes trusts biotecnológicos y sus efectos en la uniformización de la intersubjetividad, en una novela reciente como Cataratas de Hernán Vanoli (2015), es inescindible —como se intentará probar— de un uso deliberado de teorías sociales. ¿Qué función cumplen estas en una literatura que si bien se percibe como heredera de la ciencia ficción ha perdido cientificidad? A pesar de una incuestionable heterodoxia, la legibilidad genérica, y por ende, su legalidad, nunca estuvo más a salvo —diremos— entre sus recreadores.
Fin del arte, fin del tiempo.
Authors: Goldzycher Alejandro
Published: December 2020

Pasadas de moda las especulaciones sobre «el fin del arte» y «el fin de la historia», el entramado discursivo y conceptual que les dio forma en el debate norteamericano se vuelve evidente como parte estructural de su objeto. Su pregunta fundamental es aquella por la relación del presente con el pasado histórico y por la historicidad de esa relación. La trilogía novelística The Dancers at the End of Time (1972–1974–1976), de Michael Moorcock, simultáneamente enuncia, dramatiza y encarna esta preocupación. El autor —emblemática figura del fantasy y la ciencia ficción de la segunda mitad del siglo XX— proyecta hiperbólicamente sobre un futuro remotísimo una constelación de referencias culturales que evocan a la vez el fin de siècle decimonónico y «la posmodernidad». El conflicto se cataliza al irrumpir una mujer procedente de 1896 en la neoesteticista sociedad del Fin del Tiempo. Para comprender la propuesta y la importancia histórica de la serie, este artículo reúne en un mismo plano comparatístico la teorización implícita en este producto de genre fiction y las «ficciones teóricas» de autores como Jameson, Danto, Huyssen, Fukuyama, Sontag y Baudrillard. Particularmente se interroga sobre el impacto político–ideológico del reconocimiento de la constructibilidad de las «épocas» (pasadas y presentes) y sobre la posibilidad de una redención de la historia, entre los mitos del progreso y la decadencia.
La viveza criolla venezolana contemporánea y su anclaje en la historia
Authors: Flores Jordi Santiago
Published: December 2020

La viveza criolla es uno de los rasgos más reconocidamente característicos de la venezolanidad. Lo reconoce su propio pueblo. Se constata entre sus habitantes su manutención y reparto en tanto su presencia es constante en el lazo social venezolano. La viveza es una forma de entretejido sociocultural muy afín entre nosotros. Pero precisamente por ello muestra en gran medida su carácter problemático. La viveza se interpreta en los más de los casos como un agravio, un agravio a la norma o al semejante. Es reconocida abiertamente como un problema social del que, paradójicamente, poco se ha sistematizado. Así, el presente artículo propone un recorrido argumentativo que muestre los anclajes de esta viveza criolla venezolana contemporánea, tomando la noción de anclaje como un significante que nos permita abordarla como un síntoma, tesis central que quedará esclarecida al final de este trabajo.
Agrietar las palabras, inventar el silencio
Authors: Fuentes Meléan Valenthina
Published: December 2020

En Venezuela, durante la segunda mitad del siglo XX, el libro de artista se conformaba como un lugar de convergencia entre el arte gráfico y la escritura. Poemas de Gustavo Pereira Grabados de Gladys Meneses (1979) es uno de esos libros que realizan el encuentro entre visualidad y poesía a través de la contención y el silencio. Se ofrece aquí una lectura de estos poemas grabados, mientras se observan las tensiones e intercambios entre ambos medios expresivos. Asimismo se propone un recorrido por algunos de los momentos que construyen el vínculo entre palabra, mirada y experiencia.
Desarticulaciones (2010) / En breve cárcel (1981). Entre la escritura y la vida: Sylvia Molloy, las letras contaminadas de una crítica lateral
Authors: Cróquer Pedrón Eleonora
Published: December 2020

En torno a Desarticulaciones (2010) y En breve cárcel (1981) de Sylvia Molloy, este artículo se concentra en el anudamiento entre escritura y vida que hace a las letras contaminadas de la autora, la «verdad» subjetiva que comprometen y el saber entre semiótico y analítico que incorporan acerca del vínculo entre experiencia, subjetividad y lenguaje. Por encima de las categorías estancas de crítica y ficción, entre las cuales la vida trama una relación de vasos comunicantes, y más allá del trazo autobiográfico que nunca se sintetiza en una historia testamentaria del sujeto implicado en ella, se trata de identificar en los lugares de ese anudamiento la expresión de una crítica «lateral»: oblicua, marginal, fronteriza. Es decir, la práctica de lectura e intervención intelectual de una autoría excéntrica que cristaliza entre los reveses del ensayo académico y las formas profanas de lo menor. Tramada desde esa posición, y amparada en el saber que de esta manera comunica, la honda implicación subjetiva que supone la escritura de Molloy, esa forma de la «verdad» que el afecto inscribe en la letra de quien en ella se arriesga, no deja de inquietar al lector, conmovido y desconcertado ante la intensidad de lo que lee.

Para tal fin, se optó por una metodología cualitativa, donde se diseñaron e implementaron talleres, teniendo como punto de partida las concepciones de los maestros en relación con esta acción discursiva. El reporte de caso concluye con hallazgos que evidencian que se cumplió con el objetivo, en tanto los docentes transformaron sus prácticas pedagógicas en relación con las dos categorías trabajadas en los talleres.
Las tutorías de escritura académica: estrategias didácticas de una tutora novel
Authors: Núñez Cortés Juan Antonio
Published: December 2020

Las tutorías de escritura son una iniciativa de alfabetización académica en muchas universidades del mundo y en los últimos años han proliferado en universidades del ámbito hispano en general a través de los centros de escritura u otros programas o proyectos de enseñanza de la escritura académica. El presente trabajo tiene como objetivo dar cuenta del tipo de estrategias didácticas que ponen en práctica los tutores noveles durante las tutorías. Para ello, mediante una investigación de corte cualitativo, se ha realizado un análisis de contenido de las transcripciones de cuatro tutorías grabadas en audio. Los textos analizados se obtuvieron a partir de cuatro tutorías ofrecidas por una tutora de 4º año de carrera a estudiantes recién ingresados en la universidad. Las estrategias se han clasificado en tres tipos: instructivas, cognitivas y motivacionales. Los resultados muestran un predominio de estrategias cognitivas, si bien la secuencia de estrategias más utilizada (lectura en voz alta del tutor – pregunta – solución del error – explicación – elogio) da cuenta de una tendencia hacia un modelo de tutoría centrada en el tutor y el producto del texto. Esto muestra la importancia de una formación modelada de los tutores a partir de la reflexión sobre lo realizado en tutorías ajenas y propias, al margen de la instrucción explícita sobre la didáctica del proceso de escritura y de los géneros discursivos académicos. Debatir sobre estas estrategias, asimismo, puede ser útil en actividades de revisión entre pares y en tutorías académicas entre profesores universitarios y estudiantes.

La ruta de esta pandemia nos ha llevado por abismos de peligro, por paisajes y figuras que leemos y experimentamos cada uno desde nuestro propio cuerpo. Cada lectura y cada cosa que se experimenta avanzan por senderos marcados por lo extraño, por lo incierto y escuchamos la resonancia de las voces que recuerdan el olvido, que nublan el destino y que tejen madejas de angustia, rabia, dolor y desesperanza. Afrontamos uno de los carnavales más intensos en el que la vida y la muerte se juntan, no guardan sus distancias, se abrazan, se miran, se besan y hacen florecer, con su indisciplinada danza, la fantasía de estar vivos. Esto significa habitar y pensar la paradoja de la existencia que crece y florece en el ser para la muerte y en la que, siempre, habrá una fuerza inmensa para reafirmar la existencia.

The utilization of groundwater potential for irrigation has consequence for the high operational and maintenance costs of groundwater irrigation systems. One solution to these problems is the selection of high economic value crop types cultivated in groundwater irrigation lands. This study aims to determinate the alternative of types of agricultural crops that can be cultivated on groundwater irrigation land based on the quality of groundwater used as irrigation water based on the procedure: determination of groundwater quality index for irrigation, determination of types of agricultural crops based on criteria for tolerance to salt, adjustment of types of crop that have been determined with the criteria of high economic value crops, and adjustment to the types of crops that have been commonly cultivated by farmers in the local area. This procedure can be used as a solution to the absence of guidelines that can be used to determine alternative of types of agricultural plants on groundwater irrigation land. The results of this research showed the potential of ground water used as a source of irrigation water in the study site was dominated by groundwater with an index value of 70-85, where agricultural crops that could be recommended for planting were tolerant crops, moderately tolerant crops, and moderately sensitive crops to salt. The index value of groundwater quality for irrigation was mapped so obtained that zoning model of groundwater quality for irrigation and its suitability for the type of agricultural crops that can be cultivated.
Studi Kelayakan Sumber Daya Air Baku Pulau Bintan – Tinjauan Aspek Kuantitas dan Kualitas

Published: December 2020

The raw water feasibility is based on three aspects, such as quantity, quality, and continuity. This study aims to assess the feasibility of raw water on Bintan Island in quantity and quality terms The method used is a comprehensive analysis of hydrological and hydrogeological functions and water quality. The result of study shows that rainwater abundance in study location is not optimally stored as ground water due to limited catchment area and storage capacity of aquifer media which are dominated by rock units with low to moderate graduation rates (80%). The hydrogeology of study site is also dominated by local low productivity aquifer areas (70%) which are indicated by shallow aquifer layers. Therefore, the existence of reservoirs or storage is very important. The calculations results in 2017 show that raw water production of PDAM Tirta Kepri is 3,521,855 m3/year. While the community needs on Bintan Island in the same year amounted to 7,957,803 m3/year. Quality aspect analysis shows that the quality of well is lightly polluted (WQI = 0.59), while surface water is moderately polluted (WQI = 1.01). The parameter that gives the difference from two sources is iron content. Gibbs diagram analysis results show the weathering process by rainwater which erodes the land surface of bauxite mine and dissolves iron and flows along with runoff and into reservoirs. The potential for high iron pollution will increase often as Bintan Island is designated as a Special Economic Zone. Industrial and service activities will trigger acid rain which will cause a decrease in the value of rain pH and the process of dissolving iron on rocks and soil surfaces will increase.
Development and Characterization of Kevlar-Reinforced Ceramic Composite Materials
Authors: Islam Kamrul , Chowdhury Mohammad Asaduzzaman , Hossain Imran , Shuvho Md. Bengir Ahmed
Published: December 2020

Fiber-fortified polymer composite material has become ubiquitous in recent years. It is exceptionally useful in various applications because it has good mechanical properties, is lightweight, has one of a kind adaptability, is safe if consumed, has a creation process that is simple, and so on, relative to other mundane materials. Polyaramid fiber known as Kevlar fiber is fundamentally well known for its expanding applications in mechanical and cutting edge innovations like ballistic defensive layer, helicopter edges, flying machine development, pneumatic fortification, and outdoor supplies. In this investigation, the mechanical (elasticity, sway quality, lengthening at break, E-modules) and physical (thickness, water assimilation) properties of the composites under different conditions, e.g., gamma irradiation and soil degradation, are shown and then contrasted with the properties under the ordinary condition. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis examinations were used to portray the morphology, mechanical properties, and warm properties of Kevlar-strengthened earthenware composite materials. The results from SEM showed that the morphology in the created composite had fewer voids, gaps, and breaks. The nearness of O-H, C-H, C=O, and C-O ingestion tops showed the novel qualities of each example, which is affirmed by FTIR spectroscopy. The trial result uncovered that all the mechanical properties are altogether high in Kevlar-fortified artistic composite at a lower level of filler material. Then again, rigidity is continuously expanded with the expansion of filler (up to 6.33 %) material in Kevlar-glass composite.
Military and Economic Power Networks, Hedging, and Cooperation on the Korean Peninsula
Authors: Ring Jonathan , Hwang Wonjae
Published: December 2020

Is the Kim Jong-un regime genuinely pursuing a peaceful solution, to eventually give up its nuclear arsenal, after a series of summits and negotiations with the US and South Korea? We examine how military and economic power networks on the peninsula are associated with the prospect of North Korea’s denuclearization. North Korea could use its nuclear weapons program, an internal tool designed to promote national security and power, to build up power in both military and economic power networks. Drawing lessons and speculation from the literature on states’ hedging behavior, and using agent-based models, we explain that denuclearization as part of a hedging strategy would be a viable policy option for North Korea.
Manhua Modernity: Chinese Culture and the Pictorial Turn

From fashion sketches of Shanghai dandies in the 1920s, to phantasmagoric imagery of war in the 1930s and 1940s, to panoramic pictures of anti-American propaganda rallies in the 1950s, the cartoon-style art known as manhua helped define China’s modern experience. Manhua Modernity offers a richly illustrated and deeply contextualized analysis of these illustrations from the lively pages of popular pictorial magazines that entertained, informed, and mobilized a nation through a half century of political and cultural transformation.
Echocardiographic RV-E/e′ for predicting right atrial pressure: a review
Authors: Fletcher A J , Robinson S , Rana B S
Published: December 2020

Right atrial pressure (RAP) is a key cardiac parameter of diagnostic and prognostic significance, yet current two-dimensional echocardiographic methods are inadequate for the accurate estimation of this haemodynamic marker. Right-heart trans-tricuspid Doppler and tissue Doppler echocardiographic techniques can be combined to calculate the right ventricular (RV) E/e′ ratio – a reflection of RV filling pressure which is a surrogate of RAP. A systematic search was undertaken which found seventeen articles that compared invasively measured RAP with RV-E/e′ estimated RAP. Results commonly concerned pulmonary hypertension or advanced heart failure/transplantation populations. Reported receiver operating characteristic analyses showed reasonable diagnostic ability of RV-E/e′ for estimating RAP in patients with coronary artery disease and RV systolic dysfunction. The diagnostic ability of RV-E/e′ was generally poor in studies of paediatrics, heart failure and mitral stenosis, whilst results were equivocal in other diseases. Bland–Altman analyses showed good accuracy but poor precision of RV-E/e′ for estimating RAP, but were limited by only being reported in seven out of seventeen articles. This suggests that RV-E/e′ may be useful at a population level but not at an individual level for clinical decision making. Very little evidence was found about how atrial fibrillation may affect the estimation of RAP from RV-E/e′, nor about the independent prognostic ability of RV-E/e′ . Recommended areas for future research concerning RV-E/e′ include; non-sinus rhythm, valvular heart disease, short and long term prognostic ability, and validation over a wide range of RAP.
IGF1 does not overcome sexual dimorphism of body and muscle size in Mstn−/− mice
Authors: Paul Ryan , Whiteman Kim , Falconer Shelley J , Oldham Jenny M , Jeanplong Ferenc , Matthews Kenneth G , Smith Heather K , Thomas Mark , Watson Trevor , McMahon Christopher D
Published: December 2020

Insulin-like growth factor-1 (IGF1) is crucial for regulating post-natal growth and, along with myostatin (MSTN), regulates muscle size. Here, we sought to clarify the roles of these two genes in regulating sexually dimorphic growth of body and muscle mass. In the first study, we established that Igf1 mRNA was increased to a greater extent and Igf1 receptor mRNA increased earlier in male, than in female, gastrocnemius muscles during the rapid phase of growth (from 2 to 6 weeks) were unchanged, thereafter, to 32 weeks of age in WT mice (P < 0.001). In the second study, we sought to determine if supplemental IGF1 could overcome the sexual dimorphism of muscle and body mass, when myostatin is absent. We crossed myostatin null (Mstn–/–) mice with mice over-expressing Igf1 in skeletal muscle (Igf1+) to generate six genotypes; control (Mstn+/+), Mstn+/–, Mstn–/–, Mstn+/+:Igf1+, Mstn+/–:Igf1+ and Mstn–/–:Igf1+ (n = 8 per genotype and sex). In both sexes, body mass at 12 weeks was increased by at least 1.6-fold and muscle mass by at least 3-fold in Mstn–/–:Igf1+ compared with Mstn+/+ mice (P < 0.001). The abundance of AKT was increased in muscles of mice transgenic for Mstn, while phosphorylation of AKTS473 was increased in both male and female mice transgenic for Igf1+. The ratio of phosphorylated to total AKT was 1.9-fold greater in male mice (P < 0.001). Thus, despite increased growth of skeletal muscle and body size when myostatin was absent and IGF1 was in excess, sexual dimorphism persisted, an effect consistent with greater IGF1-induced activation of AKT in skeletal muscles of males.

Metodología gerencial para el mantenimiento preventivo de equipos médicos mínimos usados en habilitación de cirugías ambulatorias
Authors: Villarraga Lozano Oryana del Pilar
Published: December 2020

En la gestión del mantenimiento de tecnología biomédica de los equipos médicos mínimos para la habilitación de cirugía ambulatoria, se evidencia una deficiente organización y ejecución de los mantenimientos preventivos, lo que disminuye la disponibilidad de los equipos y aumenta las paradas y los costos en la organización de salud. El objetivo de esta metodología es orientar la gestión del mantenimiento preventivo de equipos de cirugía ambulatoria con enfoque en su disponibilidad. En la metodología propuesta, se considera el impacto operacional y global, la probabilidad de daño y el nivel de riesgo de los equipos médicos, lo que genera niveles de prioridad en la ejecución del mantenimiento preventivo. Según los resultados obtenidos, se identifica que, para cirugías ambulatorias, los tres equipos que presentan un nivel de riesgo alto asociado a su disponibilidad son la máquina de anestesia, el electrobisturí y la lámpara cielítica. Su mantenimiento debe realizarse de manera prioritaria, ya que el impacto de su carencia será alto. Se concluye que es necesario contar con equipos de respaldo —sobre todo para los que presentan mayor nivel de riesgo—, tener información verídica de la existencia de los equipos, estandarizar procesos, crear procedimientos, protocolos y capacitar al personal encargado de la tecnología.

Se utilizó una metodología de tipo exploratorio cualitativo basada en la revisión de literatura sobre el tema. De acuerdo con los resultados obtenidos, se concluye que en Colombia no se ha desarrollado un proyecto que implemente big data en gestores documentales y administre la información que contienen. Se plantea la posibilidad de desarrollar una herramienta para el análisis, recuperación, organización, transformación y almacenamiento ágil y oportuno de información.
An Inquiry into Community Members’ Use and Attitudes toward Technology in Mishkeegogamang Tepacimowin Networks
Authors: Gray-McKay Connie , Gibson Kerri L. , O'Donnell Susan , Mishkeegogamang The People of
Published: December 2020

Mishkeegogamang First Nation is a rural Ojibway community in Northwestern Ontario. Mishkeegogamang community members of all ages use a wide array of information and communication technologies (ICT) as tools in daily life, and as a means to support individual and community goals. This collaborative paper tells the story of how Mishkeegogamang uses ICT for community development, drawing on 17 interviews with community members, and several community member profiles. A basic descriptive quantitative analysis is also provided, giving information on frequency of use of a wide variety of technologies. Community informatics theory guides the interpretation of the findings. A broad range of ICT use by community members will be explored, including the Mishkeegogamang website, the busy yet invisible use of social networking sites, youth and ICT, ICT for health and education, and ICT to support traditional activities. Finally, a section on challenges and needs for facilitating ICT use is also provided. Mishkeegogamang has collaborated on a rich chronicle of its land and people in the Mishkeegogamang book: The Land, the People, and the Purpose (Heinrichs, Hiebert, & The People of Mishkeegogamang, 2009). This paper is conceptualised as a new chapter, documenting how community members use ICT in their daily lives and for community development. There have been no similar past explorations that have addressed this area. In addition, within the broader literature on First Nations in Canada, there have been few to no published accounts of community members’ perspectives and uses of ICT. This study is part of a broader collaborative research project called (First Nations Innovation), which explores how remote and rural First Nations are using information and communication technologies for community development.
How Does Internet Usage Influence On Social Capital, Connectedness, Success And Well-Being Of Grassroots Level Inventors In Sri Lanka?
Authors: Wickramasinghe Chaminda Nalaka , Ahmad Nobaya
Published: December 2020

Internet has been recognized as the world largest knowledge depositary. Therefore, there is overwhelming expectation over the Internet to be influenced the social and technological development of marginalized communities of less developed countries. However there were no published studies that investigate the nature of the innovation systems and the impact of internet on the inventors in developing countries. Therefore, the existing knowledge of how the internet usage of influence on social capital, connectedness, success and subjective well-being of inventive community in developing countries is vague. Present study explores the influence of the internet usage on social capital, community connectedness, inventive achievements and subjective well-being of the grassroots level inventive community of Sri Lanka. Findings suggest that internet has been significantly influenced on the social capital, connectedness and subjective well-being of grassroots level inventors in Sri Lanka. However, internet usage is not significantly influence on the objective inventive achievements of the inventors.

Over the past decades the Internet has become increasingly central to the actualisation of fundamental human rights. Consequently, there is a growing body of legislation and jurisprudence recognising access to the Internet itself as a human right. This paper explores the justification and nature of the claim that the Internet is a human right, before considering the implications of this understanding to efforts to expand access. This paper goes on to consider challenges to expanding access in the Canadian and international contexts, particularly with regard to social issues that limit user demand.
Building Broadband Infrastructure from the Grassroots: the Case of Home LANs in Belarus
Authors: Zorina Aljona , Dutton William H.
Published: December 2020

This paper describes the development of residential Internet infrastructure by communities of citizens in Minsk, Belarus, in Eastern Europe. Sharing resources and technologies these communities created infrastructures from the grassroots that became an alternative to an undeveloped and hardly affordable provision of Internet-access provided by Internet companies. This grassroots network became the main source of residential broadband Internet access. During the 16 years of their development (1994-2010), home LANs grew to connect a million users, created a number of important Ethernet innovations and established mutually profitable cooperative relationships with private providers and municipal organizations. This paper focuses on the innovative aspects of home LANs and describes this solution to the development of the local grassroots Internet infrastructure. The case study provides an example of user-driven innovations for the ‘First Mile’ that can address aspects of the digital divide and social exclusion, despite a variety of resource-based limitations.
Settler Colonialism and First Nations e-Communities in Northwestern Ontario
Authors: Beaton Brian , Campbell Peter
Published: December 2020

Across Canada First Nation community leaders are adopting the e-Community approach for their local broadband development. E-Community is fueled by the desire of First Nations to own, control, and manage their local infrastructure and online services. The paper develops the concept of the importance of locally owned and managed telecommunication infrastructure supporting First Nation e-Community and local resilience. The First Nations e-Community framework provides choices for local people to remain in their communities and contribute to the growth and positive development in these challenging environments. The First Nations' struggle against settler colonialism to access their lands and resources by the colonial governments and their corporate partners continues today. Strong, resilient First Nations are now in a position to influence and support outcomes that benefit themselves, the lands and others in a positive manner.
Opportunities and Challenges for First-mile Development in Rural Hawaiian Communities
Authors: Winter Jenifer Sunrise , Buente Wayne , Buskirk Patricia Amaral
Published: December 2020

The islands of Hawaiʻi are the most geographically remote locations on earth and connect to the global Internet via expensive submarine fiber. While citizens in densely populated areas such as Honolulu have several options for broadband coverage, there are gaps throughout the state. Many of those living in rural areas, including indigenous Hawaiian communities, suffer from a lack of critical infrastructures. For indigenous Hawaiians trying to gain equal access to educational and economic opportunities, health care, and linguistic and cultural preservation, this disparity is particularly troubling. We describe challenges faced by Native Hawaiian communities in developing affordable, high-quality broadband access and describe initiatives, to date, that seek to address them. We suspect that the conventional planning approach to broadband development is incongruent to the unique economic, social and cultural contexts present in Hawaiian rural communities. Our investigation explores the potential for community-initiated broadband projects that will enable indigenous Hawaiians more self-determination in the planning and management of broadband networks and services.
The First Mile Connectivity Consortium and Digital Regulation in Canada
Authors: McMahon Rob , Hudson Heather , Fabian Lyle
Published: December 2020

On June 19 and 20, 2013 the First Mile Connectivity Consortium, K'atl'odeeche First Nation and the Eeyou Communications Network intervened in a regulatory hearing about digital infrastructure and services in the Canadian north. The three parties focused on issues of access, affordability, and the potential for infrastructure development in the North to support community development. They argued that northern residents should be offered opportunities as producers as well as consumers of telecommunications services. This article provides a summary of this intervention.

Community-based Pedestrian Mapmaking
Authors: Chorianopoulos Konstantinos
Published: December 2020

Despite the widespread use of highly accurate digital maps on desktop and mobile computers, cartography has over-emphasized the needs of land use and car navigation. Previous work has considered data analysis and path finding techniques, but there has been limited consideration of the subjective perceptions in pedestrian mapmaking. Besides the immediate benefit to pedestrians, a pragmatic understanding of walking paths might facilitate urban planning and design, which is usually based on cartography. Finally, we demonstrate how the tools and techniques of cartography have influenced the image of the city with references to past and ongoing efforts.
Neighborhood Planning of Technology: Physical Meets Digital City from the Bottom-Up with Aging Payphones
Authors: Stokes Benjamin , Bar François , Baumann Karl , Caldwell Ben
Published: December 2020

What does it mean to “plan” a technology?  Designs with a footprint in public space are important hybrids, including wired bus stops and rebuilt payphones.  Our goal is to shift from designing technology for a neighborhood by planning technology as part of the neighborhood.  Aging phone booths were purchased in LA’s historic Leimert Park.  For six months, residents joined with technologists to tackle a planning issue (gentrification).  We developed a method of “deep engagement” to sustain grassroots planning in socio-technical systems, especially around the digital divide.  The method resists “solving” the payphone problem, and instead theorizes engagement as four social scaffolds to bring technology literacy into the planning process.
Empowering Newcomers with Low-Tech Workshops and High-Tech Analyses
Authors: Balassiano Katia , Seeger Christopher J.
Published: December 2020

Newcomer participation in governance is a common goal, but many traditional venues and mechanisms designed to facilitate inclusive decision-making remain inaccessible. We present a case study that uses low-tech participatory mapping workshops to help newcomers learn where people go to discuss local affairs and access information. We then analyze the workshop data with a dynamic, high-tech, Geographic Information Systems (GIS) spatial modeling process. The maps generated can be used to identify more inclusive venues for public meetings. This article describes the replicable workshop methodology, analytic tools, and benefits that result from using the two in concert.
Urban Acupuncture in the era on Ubiquitous Media
Authors: Iaconesi Salvatore , Persico Oriana
Published: December 2020

The concept of Urban Acupuncture as applied to a contemporary vision of cities, between ubiquitous technologies, social networks, sensors and cloud computing. From the possibility to listen in real time to the digital life of the city to the opportunity to design and implement novel models for participatory, co-creation practices for city governance, planning, culture, tourism, citizen activation. The paper describes the construction process of a methodology and of the required set of digital tools which allow to enact Urban Acupuncture practices in cities with high numbers of social media interactions Two case studies are included for the City of Rome and the City of Turin, showing two practical applications in the domains of culture and of multiculturalism, respectively. The two cases have been performed in collaboration and with the support of the city administrations and, in the final remarks, they are used to produce an evaluation of the proposed methodology and a series of focuses for further research and investigation
Community meeting the Namibian Education Technology Policy with OLPC's XO laptops: is it a viable approach?
Authors: Boer Perien J.
Published: December 2020

Research problem There is a need in the literature to describe the implementation processes of technology integration in education through community involvement. In particular, there is limited research available about the mechanism or process behind the community technology trends in Namibia. Few cases explore community involvement in meeting educational technology policy needs. The ICT Policy for Education and the Tech/Na! Implementation policy plan aims to prepare learners to participate in new global economies of the 21st century. It also recognizes that presently, schools and other educational institutions are ill-prepared for the demands of the 21st century (ICT policy for Education, 2004).  The policy also presupposes that integrating technology in the classroom is the appropriate vehicle to achieve the goal of knowledge, equity, quality and access for all. Although the Namibian Ministry of Education has focused on developing the technology infrastructure at secondary school level first, many educators and community activists has argued that technology integration would be more successful if implemented at primary school level.  It is for this purpose that the Ngoma community explored ways in which to integrate technology in and outside of the classroom as a community effort. Key Findings Results in this case study reveals that despite the valiant efforts of community the educational approaches and understanding of the policy hampered further advancement of these XO computers in the schools for learning. Moreover, the OLPC model approach of ownership and alleged focus on constructivist education and 'digital utopianism appeared to be conflicting in the implementation and sustainability of the community project. Community members priorities changed as the project was implemented due to events of thefts, parent complaints which resulted in short-term ineffective solutions. The Itenge Development Foundation remains an integral part of the project, however with minimal community involvement and use of laptops.
