    Glass Sandwich Panel: Exploring the potential of glass sandwich structures for relatively lightweight planar elements with high stiffness and controlled transparency.

    Transparency is embraced more and more in contemporary architecture and therefore glass has become one of the most important materials in the building industry. In structural glass applications the elements are dimensioned based on stiffness and strength requirements. This research investigates the potential of glass sandwich structures as a way to create planar elements with a high stiffness to weight ratio and reduce material consumption in structural glazing applications. The design focuses on the replacement of the glass floors of the Acropolis Museum in Athens with an aim to a)reduce material consumption, b)eliminate the supporting substructure and c)propose an optimised design. 7 different core topologies are designed and tested by means of a 4-point bending test in a way to assess the optical quality of such structures, showcase their potential and finally assess which configuration is the most suitable to be used in the aforementioned application. The topology that fulfills the structural and aesthetical requirements is furtherly investigated and its structural behaviour is “deconstructed”. The knowledge acquired through this process is used to optimise structurally and aesthetically the panels of the new glass floors.. Finally, a design toolbox is devised which constists of three phases: a)graphical/analytical calculations (predimensioning), b)Finite Elements Analysis (detailed calculation) and c)Bending Tests (evaluation). In general, this research proves the advantage of glass sandwich structures over laminated glass in stiffnes-dominated designs but also discusses the importance of integrating the process of selective distraction into the design.Architecture, Urbanism and Building Sciences | Building Technolog

    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

    Full text link
    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

    Full text link
    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Una reevaluación de una consulta oracular de Dodona mal interpretada (= Lhôte, 2006: 214-216 nº 100)

     The purpose of this study is to reassess an oracular enquiry preserved on the front of a leaden plate and to reinterpret the last line of the text. The lamella was found during excavations conducted by Demetrios Evangelides at Dodona, and was first published by him in 1935. Since then, the epigraphic text and its dialectal features have been given relatively little attention, and the problematic last line has not yet received a satisfactory reinterpretation.El propósito de este estudio es ofrecer una reevaluación de una consulta oracular conservada en el anverso de una placa de plomo así como reinterpretar la última línea del texto. La lámina fue encontrada durante las excavaciones realizadas por Demetrios Evangelides en Dodona, y fue publicada por primera vez por él en 1935. Desde entonces, el texto epigráfico y sus rasgos dialectales han recibido relativamente poca atención, mientras que la problemática última línea aún no ha recibido una reinterpretación satisfactoria
