Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Improving traceability management through tool integration: An experience in the automotive domain
No full textDespite the relevance of traceability in software processes is well-known, the activities of traceability creation and management are not always adequately supported in real software projects. The lack of integration between the tools adopted in the development processes is one of the main causes of such an ineffective management, where traceability relationships are still manually generated and maintained. In this paper we present an industrial experience we performed for improving the traceability management in a software development process performed in Fiat Chrysler Automobiles FCA company. We designed a software architecture for integrating the existing Application Lifecycle Management (ALM) platform with the tools used in the testing process. The architecture aimed at fully automating the execution of the testing process and at automatically generating the appropriate traceability links when they are established. It was implemented using a Continuous Integration Engine that allowed us to develop a modular, evolvable and reconfigurable integration architecture. The new architecture was validated by an experiment that showed its capability in correctly and completely generating and handling traceability links between artifacts involved in the testing process. The experiment demonstrated that the integration solution produced also beneficial effects on other quality attributes of the process
Robust flight control design for the HIRM based on linear quadratic control
No full textIn this paper the application of Linear Quadratic Optimal Control based techniques to the HIRM (High
Incidence Research Model) Robust Flight Control design problem is considered. The structure of the proposed
controller is basically a Proportional Integral action, both for the longitudinal and for the lateral-directional
parts, designed with optimality criteria in order to achieve the performance and robustness requirements.
Moreover, the control scheme is completed by the compensation of some physical non linearities, some
demand shaping filters and a switching logic based on the angle of attack and on the Mach number. Most of the
design requirements are easily satisfied; some others need a heavier tuning of the controller design parameters.
A procedure to tune such parameters, formulated in terms of an optimization problem, is proposed. Simulation
results, from the HIRM automated evaluation procedure are also provided at the end of the paper, from which
it is shown that the proposed controller meets the requirements
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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 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
