    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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

    [[abstract]]建安、黃初, 文章體裁漸備, 於是曹丕典論首開文論之先河。其後文論蜂出, 或探尋 文體源流, 或區分文章體類, 或講明文章作法, 或論列作家才性, 或品評作品風格 , 不一而足。在曹魏至隋三百年間之文壇大放異彩。惜乎其勒成一書, 留傳至今者, 除 文心雕龍、詩品等為數不多之著作外, 皆已散佚。然考諸現存文論、歷代史志、各家 注疏及類書所徵引者, 則其散佚之跡, 猶可得而見也。 本論文, 即旨在 考此時期文論佚書, 除探尋文論存輯情形外, 復討論可見文論之內 容旨趣, 冀能為中國文學理論發展尋得根源。 首章緒論, 說明研究動機與方法。 次章略述魏晉南北朝文論產生之時代背景。此為第一部分。 三章至六章, 分別 考魏代、兩晉、南朝、北朝之文論佚書。 三章論曹魏時期。得曹丕典論文佚文四則; 桓範世要論佚文三篇。 四章論兩晉時期。西晉得荀勗文章敘錄佚文十一則; 摯虞流別集、文章志、流別論佚 文, 為數甚多, 佔本論文之篇幅及分量最重。另得傳祇文章駁論、郭象碑論, 皆有目 無文。東晉得李充翰林論佚文十三則; 顧愷之晉文章記佚文一則。另得謝沈文章志錄 雜文、謝混文章流別本, 有目而無文。 五章論南北朝時期。宋得宋明帝晉江左文章志佚文十七則; 顏延之庭誥佚文兩篇; 丘 淵之晉義熙以來新集目錄佚文六則; 傳亮續文章志佚文五則, 另得孔甯續文章志、王 微鴻賓、張 「擿句」, 有目無文。齊得丘錄鞠江左文章錄序、陸厥文緯, 皆有目無 文。梁得沈約宋文章志、任昉文章緣起、張率文衡、佚名文章義府, 皆有目無文。 六章論北朝時期。北魏得徐紇文章駁論; 北周得明克讓文類、杜正藏文軌; 北齊得文 林館待詔顏之推等續文章流別, 皆有目無文。此為第二部分。 第七章就區分文章體類、闡釋文體名義、探尋文體淵源、深究文體流變、講明文章作 法、建立批評標準、品騭作家作品、反映時代文風等方面, 彰顯此期文論佚書之價值 。第八章分別探討此期文論佚書對文風、文論、詩論、總集之影響。末章綜理上述各 點, 彙為結構。此為第二部分。 魏晉南北朝文論佚書之風貌, 經此研究, 即可藉之得見其輪廓,而我國文學理論之形 成與發展過程, 亦得以覘其梗概矣!
