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
Occurrence and Management of Papaya Diseases after Natural Disaster
No full text為避免蚜蟲傳播木瓜輪點病毒，網室栽培已為台灣最普遍的木瓜栽培模式，台灣因位處颱風帶，颱風來襲期間的強風豪雨，網室次次掀網，均成為木瓜果疫病、木瓜黑腐病、木瓜輪點病、木瓜畸葉嵌紋病、木瓜炭疽病、木瓜蒂腐病等病原入侵的最佳時機。預防勝於治療，為減輕風災及豪雨對網室栽培木瓜帶來嚴重的損失，應選擇避風處、地勢高、土壤通氣性及排水良好地栽植，或設置防風林或防風網，做好排水工程，慎選種植時期，採行倒株栽培，提高植株抗風能力。災後木瓜病害管理需注意園區排水及整畦、田間衛生管理、設施修復、受損植株管理及藥劑防治等工作，以減少果實的損失。
Due to the devastations of papaya ring spot virus , cultivation of papaya in the net house is almost a no choice practice in Taiwan. Taiwan is located typhoon area, and papaya is grown all year round, the net house is easily broken out by typhoon /tropical storms or heavy rains which resulted in the severe occurrence of Phytophthora fruit rot , black rot , ring spot virus , leaf distortion mosaic virus, anthracnose and stem-end rot. In order to reduce the loss from natural disaster, such as typhoon, selection of the planting site to avoid strong wind plus good drainage and soil aeration is very important. If possible, the use of wind-break and enforcement of the net house strength are also very important. In order to reduce the devastating of diseases after typhoons, several practices such drainage, field sanitation, repairing of the net house, and spreading of necessary fungicides are key factors to ensure the production of papaya fruits
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
