Adopción de TIC en la Universidad Pontificia Bolivariana Bucaramanga, Colombia
(2015) Alba Soraya Aguilar Jiménez; Marianela Luzardo Briceño; Ludym Jaimes Carrillo
Information and Communication Technologies (ICTs) have introduced a road to new practices in university education, which has led institutions to confront changes in technology adoption. This article shows the results of a study conducted with teachers and students of Industrial Engineering at the Universidad Pontificia Bolivariana Bucaramanga, in order to identify factors related to ICT incorporation from four perspectives: teachers, students, methodologies and institution. An exploratory factorial analysis was conducted. Adoption rate was calculated based on studied perspectives. It concludes the importance of teachers’ role, inherent methodological changes and institutional compromise required to materialize adoption.
Conocimiento y frecuencia del uso de las tecnologías de información y comunicación en la práctica educativa. Variables sociodemográficas de los docentes en la Universidad de Los Andes
(2020) Marianela Luzardo Briceño; Beatriz Elena Sandia Saldivia; Alba Soraya Aguilar Jiménez
This study was aimed at determining the relation between socio-ethnographic features of academics of two faculties at the University of the Andes in Venezuela, and the knowledge of Information and Communication Technology (ICT) and how frequent this is used. It is a descriptive-relational study for which a questionnaire measuring academics’ ICT skills was designed. The results show that academics trained in scientific and technical areas know ICT more and use it more frequently than the ones trained in social sciences. Additionally, length of service and promotion ladder heavily influence this: academics, who are at the bottom of the promotion ladder and whose service is not long, are more likely to know ICT more and use it more frequently in teaching.
Cuán gramaticalmente complejos son los títulos de los artículos científicos en las ciencias naturales
(2015) Johanna Entralgo; Françoise Salager‐Meyer; Marianela Luzardo Briceño
This paper examines a corpus of 150 titles of research articles published between 2010 and 2013 in Anglo-American natural sciences journals (physics, chemistry and biology) in order to determine their lexical density and grammatical and morphosyntactic features. Towards that end, the frequency of present and past participles, prepositions, coordinating and subordinate conjunctions, and the frequency and length of compound words was recorded in each title. The total number of content and function words was also recorded so as to determine title lexical density. ANOVA tests were applied in order to assess whether statistically significant differences in the frequency of the above mentioned variables were detected within and across disciplines and in the whole corpus.
Factores que influyen en la adopción de las Tecnologías de Información y Comunicación por parte de las universidades: Dimensión Enseñanza-Aprendizaje
(2017) Marianela Luzardo Briceño; Beatriz E. Sandia; Alba Soraya Aguilar Jiménez; M.M Martínez; Jhobana Herrera Díaz
Este estudio permite identificar los factores que influyen en el proceso de apropiacion de las Tecnologias de Informacion y Comunicacion (TIC) por parte de Las Instituciones de Educacion Superior (IES). Para ello se realizo una revision teorica de las publicaciones de los ultimos anos. Los resultados evidencian una mejor comprension teorica de los elementos que deben tenerse en cuenta al momento de incorporar las TIC. Los factores definidos son: 1) Lineamientos pedagogicos; 2) Procesos educativos; y 3) Procesos documentados.
Factores que Influyen en la Adopción de las TIC por parte de las Universidades desde la Dimensión Organizacional
(2018) Marianela Luzardo Briceño; Alba Soraya Aguilar Jiménez; Beatriz E. Sandia; Brenda Liseth Acosta Santiago
Dada la importancia que han tomado las tecnologias de informacion y comunicacion (TIC) en la educacion y en el desarrollo del aprendizaje de los estudiantes, se realizo este estudio a fi n de identifi car los factores que infl uyen en la adopcion de las TIC por parte de las universidades, desde la dimension organizacional. Para el estudio fue necesario realizar una revision teorica conceptual de los ultimos 10 anos, basandose en diversas fuentes bibliografi cas. Los resultados encontrados evidencian una mejor comprension teorica de los elementos que, desde la dimension organizacional, deben tenerse en cuenta al momento de implementar las TIC por parte de las instituciones de educacion superior (IES), los cuales se pueden agrupar en cuatro factores: Recursos, Desarrollo Profesoral, Estrategia Institucional y Gestion Administrativa. Finalmente se puede afi rmar que si bien todos los factores son relevantes, el referido a estrategias institucionales es uno de los mas signifi cativos al implementar las TIC en una institucion educativa. Vale resaltar que en el estudio realizado se encontraron como sub–factores a considerar los siguientes: recursos fi nancieros, incentivos, politicas academicas y administrativas para el e-learning y procesos organizativos de apoyo.
Modelo de Fronteras Estocásticas en la estimación de la productividad del Sector Manufacturero Venezolano
(2020) Marianela Luzardo Briceño; Víctor E. Márquez Pérez; G H Yohana López; Ana Chacón
Se realizo un estudio de fronteras estocasticas para estimar cambios tecnologicos en escala y eficiencia necesarios en la productividad total de factores del sector manufacturero venezolano (2003-2007), con un panel de datos desbalanceado de 21 ramas de actividad economica. Los resultados demostraron que a medida que el tiempo transcurre, las ramas de actividad economica inmersas en la encuesta industrial anual que lleva a cabo el Instituto Nacional de Estadistica y los tipos de estrato (gran industria, mediana industria superior, mediana industria inferior y pequena industria) presentaron tecnologias crecientes, pero no en el nivel deseado ya que el comportamiento tecnologico fue negativo; de igual manera se observo ineficiencia productiva y una contraccion en la produccion de las empresas manufactureras venezolanas.
Titling and authorship practices in medical case reports: a diachronic study
(Equinox Publishing, 2014) Françoise Salager‐Meyer; Marı́a Ángeles Alcaraz Ariza; Marianela Luzardo Briceño
This paper is a diachronic analysis of a corpus of 180 titles drawn from Case Reports (CRs) published in the BMJ and BMJ Case Reports between 1840 and 2009. The corpus was divided into three blocks, and the frequency of occurrence of 69 text-internal variables was recorded in each title. Between-block comparisons were carried out, and Student's t-tests were applied to the quantitative results. Our findings show that CR titles have evolved over the 160-year period studied in the sense that they have increased in length, syntactic complexity, semantic richness and title-type diversity. Authorship patterns and collaboration practices have changed too. Although internationalization of case reporting has increased over time, today's preferred practice is still local collaboration. The only variable that has remained constant over the years is the nominal nature of CR titles. We put forth several social and scientific factors that could account for the various shifts observed. We claim that non-informativeness of CR titles that persisted over time can be explained by the fact that CR authors are reluctant to give a generalization flavor to their findings.
