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
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
(36(1):29-40)Accumu1ation and Distribution of Nutrients Soybeans－III. Accumulation of TNC, N, P, K and Mg during Plant Development
No full text以高雄3 號（Kaohsiung No.3 ）與十石（Shih-Shih ）二大豆品種為材料，於重要生育期測定植株各部位所累積之非構造性碳水化合物（TNC ）及氮、磷、鉀與鎂素含量，並於春、夏作間進行比較，以探討營養要素與產量間之關係。在R4-R5 生育期以前，葉片為營養要素累積量最高的器官，且春作大豆全株與各營養器官內的要素含量多較夏作為高，其後之營養要素累積以莢果壁與種子為主，且以夏作的含量較多。全生育期大豆植株累積各要素之最高量為每公頃氮素124-270kg 、磷素27-42kg 、鉀素70-130kg 與鎂素15-30kg ，其中僅磷素與所施用之肥料量相平衡。種子迅速充實期全株各元素之累積速率（kg / ha / day ）為氮素3-8 、磷素0.3-1.2 、鉀素1.4-3.8 與鎂素0.3-0.8 ，而種子之累積速率則依次為4.4-12.9 、0.7-1.7 、1.8-2.6 與0.3-0.5 ，顯示除鉀與鎂外，其他營養要素明顯自葉片、葉柄、莖桿及莢果壁等器官再轉移至種子。種子充實期間莢果壁TNC / N 比值上升，夏作遠高於春作，種子TNC / N 比值則有逐漸下降的趨勢，且以春作略低，顯示夏作大豆TNC 生產力較高，春作則有不足的可能，應為影響產量的重要原因。
Soybean varieties Kaohsiung No. 3 (KS 3) and Shih-Shih (SS) were grown in the summer (1981) and spring (1982) crop seasons to study the amounts of TNC, N, P, K and Mg accumulated by different plant organs during successive developmental stages. Between V3 and R5 stages, leaf blade was the organ of predominant nutrient accumulation and the amounts accumulated by the whole plant and various vegetative organs were greater for the spring than for the summer crop. Pod wall and seed were the major organs of nutrient deposition during seed-filling. The amounts of TNC and mineral nutrients accumulated in the reproductive organs as well as in the whole plant were higher for the summer crop during the same period. The maximum amounts of nutrients accumulated by soybean crop were 120-270 kg N/ha, 27-44 kg P/ha, 70-130 kg K/ha and 15-30 kg Mg/ha. The accumulation rates (kg/ha/day) by the whole plant during rapid seed-filling were N: 3-8, P: 0.3-1.2, K: 1.4-3.8 and Mg: 0.3-0.8; whereas the rates by the seed were N: 4.4-12.9, P: 0.7-1.7, K: 1.8-2.6 and Mg: 0.3-0.5. These results indicated significant retranslocation of N and P from vegetative organs to the developing seeds. TNC/N ratio in the pod wall increased markedly during seed-filling and was significantly higher for the summer than for the spring crop. On the contrary, TNC/N ratio in the seed showed a decreasing tendency during the same period. It was also slightly higher for the summer crop. Poor ability of TNC production was suggested as one of the factors for the low grain yield of soybeans grown in the spring crop season

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.
