    Análisis dinámico de estabilidad de taludes por medio de elementos finitos
    (2016) Bojorque Iñeguez, Jaime Asdrúbal
    This manuscript presents the results of an analysis, parameter by parameter, that affect the displacement of a slope when subjected to dynamic loads. The effect of the shape of the dynamic record through parameters such as frequency, amplitude and duration is evaluated. Also, the soil characteristics are investigated considering the specific gravity, Young's modulus, Poisson's ratio, cohesion, friction angle and damping. The displacement of the crest of a slope can indicate the performance of stability, hence the use of numerical techniques such as finite element helps to understand the effect that an earthquake (dynamic load) could have on the generation of deformations. Traditional methods such as pseudostatic and Newmark do not consider the characteristics of the earthquake. To better capture the effects of an earthquake, parameters such as frequency, amplitude and duration should be considered as to make a reliable estimate of displacements, which can be done by a dynamic analysis using finite elements.

    Improving the publication visibility of Ecuador’s higher education system
    (2016) Feyen, Jan; Milia, Matías Federico; Van Hoof, Hubert B.; Quinde Herrera, Karina Sandra; Ochoa Robles, María Verónica; Abril Ulloa, Sandra Victoria; Bojorque Iñeguez, Jaime Asdrúbal
    This article reports on a comparative study between the publication productivity of Ecuador’s leading Higher Education Institutions (HEIs) (as reported in the SCOPUS journal/proceedings database; https://www.elsevier.com/solutions/scopus) and the publication efforts of similar universities in South America and Western Europe when those universities converted from a “teaching-only” to a “teaching and research” focus. The authors highlight the causes of Ecuador’s research and publication paucity and suggest remedial strategies which focus on adjusting the profile and activities of Ecuador’s HEIs to better meet the skills gap in the 21st century economy; economy driven by innovation and knowledge. The article proposes that Ecuador’s HEIs make teaching collaborative and more affordable, stimulate faculty to examine society-relevant problems in teams, educate and encourage faculty to publish in peer-reviewed journals and enhance effectiveness and efficiency so that a stronger teaching-researchservice nexus emerges; all even though Ecuador has entered a period of economic hardship with dwindling funds for higher education.
