    The constant threat of a strong seismic event in the country forces us to design buildings that will behave properly under such event, where protecting people’s life is the number one priority. Thus, a ductile moment resistant steel frame was used. This type of structural configuration assures the generation of energy dissipation mechanisms that will allow to have an appropriate behavior during an earthquake...La constante amenaza de un evento sísmico fuerte en el país nos obliga a diseñar edificaciones que tendrán un comportamiento adecuado bajo dicho evento, buscando siempre cuidar la vida de las personas que se encuentren dentro de la estructura. Tomando esto en cuenta se empleó un diseño en acero usando marcos dúctiles resistentes a momento, este tipo de configuración estructural garantiza la generación de mecanismos de disipación de energía que permitirán tener el comportamiento esperado durante un terremoto..

    Embedded column base (ECB) connections are critical components within a structure. They are responsible for transmitting axial loads, shear and moments from the entire structure to the foundation...Las conexiones compuestas por una columna de acero embebida en un pedestal de hormigón, son componentes críticos dentro de una estructura. Esto debido a que son las encargadas de transmitir las cargas axiales, cortantes y momentos de toda la estructura hacia la cimentación..

    The structural design of the housing project "Casas Delmonte" located in the city of Quito, in the Vista Hermosa neighborhood of Conocoto was developed. The project consists of 4 housing units, located on a 900 m2 lot. Each house in the project has a construction area of 136.6 m2, where the first and second floors are 68.3 m2. The structural design is aimed at a project home since all homes have the same architectural and structural design...Se desarrolló el diseño estructural del proyecto habitacional “Casas Delmonte” ubicado en la ciudad de Quito, en el barrio Vista Hermosa de Conocoto. El proyecto consiste en 4 unidades de vivienda, ubicadas en un lote de 900 m2 de área. Cada casa del proyecto tiene un área de construcción de 136.6 m2, donde la primera planta y segunda planta son de 68,3 m2. El diseño estructural va dirigido a una vivienda del proyecto ya que todas las viviendas tienen el mismo diseño arquitectónico y estructural..

    Due to the great progress in construction that has taken place in recent years, it has been seen that metal structures are beginning to have a greater reception due to their faster construction. Given the need to build a residential home in the city of Manta, a structural steel design has been made which facilitates the manufacture and installation of the structural members...Debido al gran avance en la construcción que se ha dado en los últimos años, se puede notar que las estructuras metálicas están comenzando a tener una mayor acogida debido a su construcción más rápida. Ante la necesidad de construir una vivienda habitacional en la ciudad de Manta, se ha realizado un diseño estructural en acero el cual facilita la fabricación e instalación de los miembros estructurales..

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
