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
Genetic architecture of dusunic, murutic and paitanic ethnic groups of Sabah, Malaysia as revealed by high density genotyping arrays
Get PDFThe native ethnic groups of Sabah are categorized under the 'North Borneo' stock of the Austronesian linguistic family. It is generally believed that the native groups of Northern Borneo are plausibly descendants of the 'Out-of-Taiwan' Austronesian wave of human migration. While there may be some anthropological evidence support for this, the lack of genetic evidence makes the hypothesis inconclusive. As such, this study aimed to unravel and compare the population metrics, genetic structure and genetic relationships of the Northern Borneo indigenous ethnic groups (North Borneans) against Southern China and Southeast Asian populations, and subsequently provide inference of their migration history. Ethical clearance was obtained and blood samples were collected from healthy individuals. A total of 117 individuals representing five indigenous ethnic groups namely Dusun, Rungus, Sonsogon, Sungai-Lingkabau and Murut-Paluan were genotyped with -2.4 million genome-wide single nucleotide polymorphism (SNP) markers. The genotype data were then merged with public datasets i. e. HapMap, Human Genome Diversity Project (HGDP), Singapore Genome Variation Project (SGVP), and Pan-Asian SNP Consortium( PASNP) data to form a comprehensive meta-data set composing of 89 regional and worldwide populations. Population metrics namely decay of linkage disequilibrium, genetic heterozygosity, genetic differentiation (FsT) and phylogeny were analyzed. Next, comparative population genetic structure analysis was performed to determine the genetic gradient among populations, and to assign genetic component and its admixture across the tested populations. Finally, the genetic relationships among populations were inferred by a combinatorial correlation of these outputs. The results showed that the North Borneans were subdivided into three subgroups which were 'Dusun-Rungus', 'Sonsogon-Sungai', and 'Muruts'. The 'Sonsogon-Sungagi' rouping, which is made up of Dusunic and Paitanic-speakingg roup respectively,indicated that the linguistic groupings of the ethnic groups do not necessarily reflect their genetic affinity. Meanwhile,t he North Borneans had reduced heterozygosity and were highly differentiated among themselves. Clustering with principal components clearly depicted that each ethnic group is an independent genetic entity. As a whole, they formed a unique genetic ancestry, which was not found in previous reports. Importantly, they were closest to the non-Negrito Filipinos and the Cosmopolitan Malays of Singapore. However, phylogenetic analysis clustered the North Borneans to the Filipinos and Taiwan Natives, but not to other Island Southeast Asians. On the contrary, the Bidayuhs (West Borneo) was clustered with the Javanese and Temuans. Subsequent estimation of gene flow direction revealed that statistically probable migration event(s) was unidirectional, from North Borneo towards mainland Southeast Asia, but not the reverse. As such, a new hypothesis is postulated that the five ethnic groups descended from Taiwan Natives and Borneo Island served as one of the cross-road for two distinct waves of migration from mainland Southeast Asia and Taiwan, respectively. In conclusion, the findings indicated that Sabah's indigenous population, as a whole, has a unique yet distinctive pool of genetic variants, which are important for anthropological and medical genetic studie
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.
