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
Record of Numonia pirivorella (Lepidoptera: Pyralidae) from Taiwan
No full text梨雲翅斑螟（Numonia pirivorella (Matsumura)）又稱梨大食心蟲、梨斑螟、冒糞蟲、吊死鬼、梨大，隸屬鱗翅目、螟蛾科（Pyralidae）(1, 2, 4)，其異名有Acrobasis pirivorella (Matsumura)、Eurhodope pirivorella (Matsumura)、Nephopteryx pirivorella Matsumura、Numonia pirivora (Gerasimov)、Rhodophaea pirivorella (Matsumura)；英文名有pear fruit moth、pear moth、pear pyralid。是梨樹的重要害蟲，危害花芽、花序、幼果(1, 4, 7)，有時也危害杜梨和蘋果(2)。在前蘇聯之某些年份，此蟲危害率可達60-70 % (13)，甚至高達90 %的被害率(7)。1999 年3 月上旬苗栗縣大湖鄉廖建青農友發現其梨園之幼果被蛀食為害，被害果最後乾縮變黑（圖一）。後於3 月下旬將採得之一批被害幼果送到行政院農委會農業試驗所要求鑑定學名。筆者等幸運的於4 月上旬成功的自該批在幼果中已化成黃褐色蛹（圖二）之樣本中飼育得3 隻成蟲，並鑑定為梨雲翅斑螟。筆者等復於四月下旬收到28 粒被蛀食的梨幼果，經檢查其中26 粒被梨雲翅斑螟危害（其幼蟲腹足趾鉤呈三序環），另2 粒被桃折心蟲（Cydia molesta (Busck)）危害（其幼蟲腹足趾鉤排序呈單序）。桃折心蟲隸鱗翅目捲葉蛾科（Tortricidae），又稱梨小食心蟲、東方蛀果蛾、梨小、桃折心螟等，是一種世界性的大害蟲(1, 4)。在臺灣已知之寄主植物有枇杷、蘋果、梅、木瓜、櫻、桃、梨及李等(3)。至於梨雲翅斑螟，經查閱臺灣鱗翅目名錄(8)、經濟重要性鱗翅目索引(16)及中國大陸(1,4)與日本(9)文獻，均沒有該蟲分布於臺灣之記錄。唯獨歐洲檢疫有害生物第二版記錄該蟲分布於臺灣、中國大陸、俄羅斯（遠東區）、日本及韓國(5)；但該書並未指出引用之文獻，故筆者等對其中臺灣之記錄持保留的態度。該蟲有可能是經由接穗侵入臺灣，惟何時侵入已不可考。自1999 年至2001 年於當地未再捕獲此種害蟲，故推測此新記錄害蟲是由進口接穗時，夾帶蟲卵或幼蟲而引入，但並未立足造成為害。由於此害蟲已被地中海及歐洲植物檢疫組織（EPPO）列為A1 級檢疫害蟲(5)，而且與台灣地理位置相近之中國大陸亦為疫區的檢疫高風險性下，為預防此害蟲再侵入，農民應於嫁接穗木時，檢視接穗枝條上有無蟲卵、幼蟲，發現被害花芽應予銷毀，以降低此害蟲侵入為害之風險。
Larvae of Numonia pirivorella (Matsumura), a pest of pear, are detected in infested pears from an orchard at Mioli in Taiwan for the first time in 1999. However it is not found in subsequent investigations
