Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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 PDFWe 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 PDFWe 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

Real-time finance management system
Get PDFDiscusses the development of a real-time finance management system (RFMS) computer application. RFMS lets users learn about and manage their personal finances and stock portfolio. Finances can be managed using management tools and calculators. The program uses a Java/XML based approach where real-time market data from different stock exchanges is fetched and displayed for the user. Stock performance can then be graphed
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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

THREE-DIMENSIONAL NONLINEAR SOIL-STRUCTURE INTERACTION ANALYSIS OF PILE GROUPS AND ANCHORS.
No full textAnalysis and design of structures supported by geological media pose various complexities such as nonlinear behavior of supporting media, nature of loading, irregularities in geometry and boundary condition, and the interaction effects. It is extremely difficult to find closed-form solutions for such problems. So often, numerical techniques such as finite difference, finite element and boundary integral methods are used. In this research two soil-structure interaction problems are analyzed using the finite element method involving fully three-dimensional idealizations. In order to incorporate nonlinear behavior of a soil, a nonlinear elastic (hyperbolic model), and generalized single surface plasticity model including hardening are implemented in the finite element program for analysis of a pile group foundation, and an anchor in sands, respectively. The parameters required to define these models are determined from comprehensive laboratory stress-strain data obtained by using a multiaxial testing device. Typical stress paths are back predicted using the generalized plasticity model to verify that it is capable of predicting those paths, and is found to be satisfactory. In order to include the interaction effects resulting in relative slip and debonding or crack and openings at the junction between two dissimilar materials, the thin-layer element model is implemented. Load deformation behavior, force and stress distributions in various components of pile group foundation, and the anchor-soil system are predicted by using the numerical procedure. The predictions are compared with results from a model test for the pile group and field observations for the anchor problem; the comparisons are found to be satisfactory. The effects of soil nonlinearity and interface behavior are also delineated and it is found that their inclusion, particularly in case of anchors analysis, can substantially effect the behavior of the system. Detailed analysis of the results permits an increased understanding of the stress deformation mechanisms of the three-dimensional problems.This item was digitized from a paper original and/or a microfilm copy.
