La sociedad, los negocios y la tecnología cambian rápidamente, es por eso que la percepción del aprendizaje tiene que ser cambiada para poder mantener el ritmo frente al ambiente competitivo. En la actualidad ha habido un cambio significativo en la enseñanza superior y en el proceso de aprendizaje en general, con el auxilio de las tecnologías de la información y comunicación (TIC) y, especialmente, debido a Internet. En este contexto se destaca la EaD (Educación a Distancia). Esta a su vez ha presentado expansión en el mercado y también comodidad al alumno, pues él escoge el horario y dónde quiere estudiar. Esta investigación tiene el objetivo de evaluar la calidad (a través de la escala SERVQUAL y del modelo gap) de la EaD en una institución ubicada en Rio Grande do Sul. También la investigación se propone refinar (validar) un instrumento de investigación, para perfeccionarlo, utilizando el análisis factorial. Los resultados apuntaron que en la institución analizada existen gaps (vacíos) a ser llenados. Y el análisis factorial se mostró útil para el refinamiento del instrumento de investigación. Pues, eso hizo que hubiera mayor homogeneidad entre las variables de cada dimensión. Por lo tanto, la investigación se muestra útil tanto a nivel académico como empresarial.

The aim of this study is to analyze the level of reading comprehension skills in students of a subsidized school in the city of Iquique, Chile. The study was carried out with 79 2nd , 3rd and 4th primary school students, divided into 43 girls and 36 boys. The group was evaluated using reading comprehension tests that consist of literal, inferential and critical levels. Due to the results, the students were classified into three other groups: the insufficient level group , the elementary level group and the achiever level group. The results showed that the level of reading comprehension diminishes while the grade increases. No greater differences were observed in the results by genre, even though there exist a slightly higher result on boys. These findings also show that in relation to girls boys are more disperse in their results the distribution according to the level of reading comprehension skills is similar to approximately 30% of the students in each of the groups that they have been classified.

El marketing aplicado a las tecnologías modifica las prácticas y vías tradicionales en las que se ejecuta la información y la comunicación. Bajo la noción acerca de la composición básica del marketing tradicional que es definida por producto, precio, plaza y promoción. La estrategia de marketing con enfoque en las tecnologías transforma las reglas y amplían la noción incorporando asociaciones y la protección a los derechos autorales. La promoción de un producto tecnológico educativo gratuito mediante diversos recursos (redes sociales) conduce al usuario al acceso y aprendizaje de diferentes servicios. Hablando de Marketing, en el campo de la educación, es importante que las variables del producto/servicio tecnológico estén disponibles y con fácil acceso. Estudio señalan que la esencia del marketing comienza en la idealización del concepto, basándose en las necesidades presentadas por el objeto en estudio, concepto realizado a partir de una planeación para establecer acciones y propuestas. La vertiente de esta investigación tiene el enfoque en la tecnología de la información en marketing, un recurso de la filosofía de la gestión administrativa, y es entendido como una de las tareas del marketing dirigido a la información, buscando suministrar resultados positivos a las organizaciones. El objetivo de la investigación es la aplicación de esa vertiente a la Educación por medio de la divulgación de un Curso Online Masivo Abierto o MOOC por sus siglas en inglés (Masive Open Online Courses) partiendo del recuso de un video paper disponible en el Repositorio de Contenido de Información en Filmes (RECIF), dónde se conceptualiza este video como un Recurso Educativo Abierto (REA). De esta forma el curso es ofrecido sin costos, de forma libre y el aprendizaje es autónomo, permitiendo aún su reutilización por diferentes vías de administración educativa. El video paper del curso fue idealizado en el Encuentro Latinoamericano de Edificaciones y Construcciones Sustentables – ELECS en sus versiones 2013 y 2015m. En esta investigación la reutilización de video papers bajo la forma de un curso se define en el transcurso de la misma como una estrategia de marketing de la información que favorece la diseminación del tema sustentabilidad ambiental. Las redes sociales involucradas fueron Facebook®, Twitter®, entre otras. Por lo que se procedió a realizarse una planeación de una campaña de marketing seguida de la inserción en la internet conforme a la formulación de un plan de marketing basado en la literatura estudiada. El monitoreo de las acciones y sus resultados fueron medidos en la búsqueda de indicadores a partir del número de visualizaciones de los videos antes y después de la campaña de marketing. En resumen, en la investigación una vez que se usa el concepto REA al video paper, se aplica una vertiente del marketing – de la información – a fin de diseminar el curso en redes sociales y adecuarlo a las exigencias de un MOOC.

The authors would like to thank Mr. Francisco Fernández Fábregas, owner of the Transfiguration of Christ for allowing us the privilege of studying this painting. We also acknowledge the collaboration of Angela Tate., This paper presents a complete framework for capturing and processing hyperspectral reflectance images of artworks in situ, using a hyperspectral line scanner. These capturing systems are commonly used in laboratory conditions synchronized with scanning stages specifically designed for planar surfaces. However, when the intended application domain does not allow for image capture in these controlled conditions, achieving useful spectral reflectance image data can be a very challenging task (due to uncontrolled illumination, high-dynamic range (HDR) conditions in the scene, and the influence of chromatic aberration on the image quality, among other factors). We show, for the first time, all the necessary steps in the image capturing and post-processing in order to obtain high-quality HDR-based reflectance in the visible and near infrared, directly from the data captured by using a hyperspectral line scanner coupled to a rotating tripod. Our results show that the proposed method outperforms the normal capturing process in terms of dynamic range, color and spectral accuracy. To demonstrate the potential interest of this processing strategy for on-site analysis of artworks, we applied it to the study of a vintage copy of the famous painting “Transfiguration” by Raphael, as well as a facsimile of “The Golden Haggadah” from the British Library of London. The second piece has been studied for the identification of highly reflective gold-foil covered areas., Spanish Ministry of Economy and Competitiveness, DPI2015-64571-R, ECQM2018-004952-P

Citation classics identify those highly cited papers which are an important reference point in a research field. To identify a paper as a citation classic we have to fix a citation threshold value. Usually, this threshold value should not be the same for all research fields because each field presents its respective citation pattern. Studies of citation classics in the literature define particular criteria and methods to set citation thresholds, which are often set arbitrarily and designed ad-hoc, and do not allow the scientific community to validate and compare their results. In this paper we introduce the concept of H-Classics to overcome this problem and provide scientific community a standardization of key constructs. We present a new and systematic method to identify citation classics. This identification method of highly cited papers is based on the H-index and thank to the properties of H-index it is sensitive to the own characteristics of any research discipline and also its evolution. Therefore, the concept of H-Classics allows to systematize search procedure of citation classics for any field of research.

espanolLas TIC suscitaron una revolucion en los modelos educativos, influyendo directamente en las practicas docentes. No obstante, los medios digitales carecen de espacios virtuales que orienten y ayuden a los profesionales.

However, digital media lack virtual spaces that guide and help professionals. The development of Open Educational Resources (OER) and Learning Objects (LO) has been increasing. The objective of this research is to present a model of sharing and collaboration that fosters access and guides professionals to the use of multimedia resources as an educational offering. The methodology consists of an exploratory investigation followed by applied research based on the development of a platform where MOOCs were offered. The study was carried out at a Higher Education Institute at the University of Rio Grande do Sul, Brazil. As a result of this research, the Open Access Platform called RECIF was created, observing the collaboration and sharing of ideas among education professionals, thus making possible the verification of the proposed model. It was concluded that the proposed model can be applied in any educational practice that includes videos as a didactic resource; encourages learning that stimulates creativity and dynamism; and fosters the creation of motivational, interactive, collaborative and innovative virtual spaces.

To analyze the past, present and future of a particular research field, classic papers are usually studied because they identify the highly cited papers being a relevant reference point in that specific research area. As a result of the possible mapping between high quality research and high citation counts, highly cited papers are very interesting. The objective of this study is to use the H-classics method, which is based on the popular h-index, to identify and analyze the highly cited documents published about aggregation operators in the research area of group decision making. According to the H-classics method, this research area is represented by 87 citation classics, which have been published from 1988 to 2014. Authors, affiliations (universities/institutions and countries), journals, books and conferences, and the topics covered by these 87 highly cited papers are studied., The authors would like to thank FEDER financial support from the Projects TIN2013-40658-P and TIN2016- 75850-P.

This work focuses on the improvement of a multispectral imaging sensor based on transverse field detectors (TFDs). We aimed to achieve a higher color and spectral accuracy in the estimation of spectral reflectances from sensor responses. Such an improvement was done by combining these recently developed silicon-based sensors with color filter arrays (CFAs). Consequently, we sacrificed the filter-less full spatial resolution property of TFDs to narrow down the spectrally broad sensitivities of these sensors. We designed and performed several experiments to test the influence of different design features on the estimation quality (type of sensor, tunability, interleaved polarization, use of CFAs, type of CFAs, number of shots), some of which are exclusive to TFDs. We compared systems that use a TFD with systems that use normal monochrome sensors, both combined with multispectral CFAs as well as common RGB filters present in commercial digital color cameras. Results showed that a system that combines TFDs and CFAs performs better than systems with the same type of multispectral CFA and other sensors, or even the same TFDs combined with different kinds of filters used in common imaging systems. We propose CFA+TFD-based systems with one or two shots, depending on the possibility of using longer capturing times or not. Improved TFD systems thus emerge as an interesting possibility for multispectral acquisition, which overcomes the limited accuracy found in previous studies.
