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
Editorial
Get PDFIt is already three years since the launch of the first issue of the Journal of Materials and Engineering Structures (JMES) in 2014, with eleven (11) issues already published. We are preparing to start this fourth year with the publication of this twelfth issue, which contains five articles from four different countries (Egypt, Morocco, India and Nigeria).
The first article is devoted to the study the effect of stirrups as shear reinforcement in enhancing the punching strength of interior slab-column connections. The parameters of the study are the presence of shear reinforcement and stirrups concentration around the supporting column. The article shows that a good distribution of the stirrups on the critical perforation shear zone is an efficient solution to enhance not only the punching shear capacity but also the ductility of the connection.
The second paper deals with the dislocation nucleation phenomena in nanomaterials obtained by hetero-epitaxial growth of thin films on substrates having lattice mismatch defects. The article develops theoretical calculation on the principle of nucleating edge dislocations from free lateral surfaces by the theoretical calculation, using the method of image stress and energy study.
The third article presents a study the development of Self Compacting Concrete (SCC) using copper slag (CS) as fine aggregates with partial and full replacement of sand. The authors observed that the fluidity of SCC mixes was significantly enhanced with the increment of copper slag. The results of the tests showed that copper slag has the potential to replace sand in the range of 40-60% to obtain SCC with desirable fresh and strength properties. The use of copper slag (industrial waste) reduces the dosage of superplasticizer, consumption of natural resources which is a solution to decline the cost of concrete and boon for construction industry.
The fourth paper aims to assess geotechnical properties of uncemented/cemented clayey soil incorporated with waste crumb rubber. Authors concluded that unconfined compressive strength and split tensile strength of rubberized cemented clayey soil decreases with the increase of the percentage of crumb rubber whereas the axial, and diametral strain are found to be increased with the addition of crumb rubber up to 5% after that it starts to decrease. The CBR values (California Bearing Ratio), swelling pressure, and toughness index of uncemented/cemented clayey soil was significantly affected by incorporation of crumb rubber.
The fifth paper investigated the effect of fly ash, silica fume and metakaolin on the air permeability of Portland cement concrete at equal water/cement ratios and strengths. At equal water/cement ratios, while fly ash binary cement concretes have higher coefficients of air permeability than Portland cement concrete due to delayed pozzolanic reactivity, silica fume and metakaolin binary cement concretes have comparable coefficients with Portland cement concrete. The ternary cement concretes have coefficients comparable with that of Portland cement concrete. The author concluded that high volume fly ash would be required to increase the resistance of concrete to air permeability at equal strength.
During the first few years of JMES existence, we have tried to respect the regularity in the publication of the issues with a quarterly frequency, and by publishing for each issue a number of articles ranging from four to five with the goal of maintaining a certain level of scientific quality which reflects the ambitions and objectives that JMES has set itself.
At the moment when we are closing this twelfth issue, JMES is being evaluated by two of the most respectable scientific databases which are DAOJ (Directory of Open Access Journals - https://doaj.org) and COMPENDEX (https://www.elsevier.com/solutions/engineering-village/content/compendex). All this would not have been possible without the assistance and the help of expert colleagues, who have done us the honor of evaluating the numerous papers submitted to the JMES during its first three years of existence. We are also taking advantage of this opportunity to renew our confidence in the members of the Reading Committee for the next years.
The journal JMES which is yours continues its reflection on its evolution and aims to position itself as a scientific journal indexed in scientific databases respectable and recognized by the international scientific community. It is in this mind that the Editorial team reiterates its call to all national and foreign researchers to contribute by the quality of their articles to the success of JMES which is theirs and which is a tool for promotion and sharing of their research through their publication.
We wish you a good reading.

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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
