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
Synergism and antagonism of the four different herbs in an anxiolytic herbal formula
No full textClassical benzodiazepines are the most frequently prescribed drugs acting on the central nervous system (CNS). They exert their therapeutic effects via binding to the benzodiazepine-site of the type A γ-aminobutyric acid (GABAA) receptors, which changes the channel opening frequency. The positive modulation of BZ causes behavioral effects such as anxiolysis, sedation, myorelaxation and amnesia and these effects could be governed by the different subtypes of GABAA receptor. Formula A, a dried decoction of four herbal constituents including Flos Albiziae (F), Caulis Polygoni Multiflori (C), Rhizoma Corydalis Yanhusuo (R) and Radix Bupleuri (B), was documented as an anxiolytic. However, no detail studies with regards to its effectiveness, the possible dispensability of its constituents and possible synergism and antagonism of its anxiolytic effect were performed. In this thesis, dissection and analysis of the decoction of Formula A for its behavioral effects in vivo and in vitro experiments were done. For in vivo experiment, elevated plus maze, holeboard, rotatod, passive avoidance test were done to profile its anxiolytic, sedative, myorelaxant and amnesia respectively. While in vitro experiment of radio-ligand binding assay and whole-cell patch clamp will be carried out to show its interaction with possible binding sites. In the results, extracts of F and C had shown mutual antagonism in their anxiolytic effect while extract FRB was able to induce an enhanced anxiolytic-like effect with heavy sedation. Both extract FCB and Formula A induced an additive anxiolytic-like effect without other detectable accompanying effects. However, Formula A could induce a higher degree of anxiolytic effect as compared to extract FCB. In electrophysiological experiment, Formula A and the mono-extracts C, R and B were shown to induce hyperpolarization in rat cortical neurons; in addition, Formula A and extract C-induced currents could be enhanced by co-administration of diazepam.</p
韓寒散文作品語言特色及其變化之分析
Full text link韓寒的散文寫作手法別樹一格。在1999年，韓寒參加新概念作文大賽即席創作，以〈杯中窺人〉一文奪下首獎。他自此踏上了散文創作之路，出版不同的散文集，如《通稿2003》、《飄移中國》、《青春》等。當網絡熱潮興起，他在博客發佈大量的散文，內容主題多樣，漸具個人寫作特色。而隨時間的推移亦可看出他的散文風格上有所轉變。
本文選取韓寒不同時期的散文集作研究對象，包括：《零下一度》、《通稿2003》、《青春》、《飄移中國》、《出發》和《我所理解的生活》，從語音、語匯、修辭和語法四方面，分析其散文作品寫作語言特色及變化。
