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
Relationship between solvation structures and functionalities of proteins in ionic liquids
Full text linkイオン液体は難揮発性・難燃性といった特性をもつため、電気化学・生体機能デバイスへの応用が期待されている。本研究では、周波数変調型原子間力顕微鏡（FM-AFM）を用いたイオン液体の3次元溶媒和構造可視化技術の開発を行い、プロトン性イオン液体であるEthylammonium nitrate (EAN)および非プロトン性イオン液体である1-Ethyl-3-methylimidazolium dicyanamide (emim-DCA)の水溶液中において原子分解能3次元溶媒和構造の可視化に成功した。更に、分子動力学計算を用いて、溶媒和構造のシミュレーションも行った。Ionic liquids are expected to be applied to novel electrochemical and biofunctional devices due to their unique properties such as nonvolatile, nonflammable and high electric capacity. In this study, we visualized three dimensional solvation structures in aqueous solutions of a protic ionic liquid, Ethylammonium nitrate (EAN), and an aprotic ionic liquid, 1-Ethyl-3-methylimidazolium dicyanamide (emim-DCA) and revealed the relationship between the surface/solution properties and the solvation structures by ultra-low noise frequency-modulation atomic force microscopy (FM-AFM) with 3D-force mapping technique. In addition, we simulated the solvation structures by molecular dynamics technique and gained deep insight into the molecular structures.研究課題/領域番号:15K17467, 研究期間(年度):2015-04-01 – 2017-03-31出典：「イオン液体中における機能性膜タンパク上の溶媒和構造と生体機能との相関の解明」研究成果報告書 課題番号15K17467

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
Dynamics of Biomolecules studied by High-Speed AFM with Optical Tweezers
Full text link高速AFM/光ピンセット複合装置に特化した制御・解析プログラムを新規に開発し、これら二つの手法を同期して制御可能なシステムの構築を行った。更にモデル試料系として、長鎖ヘアピンコンカテマーアッセイの合成手法の開発にも成功した。こうして構築した実験系を用いて、ヘアピンDNAのアンフォールディングおよびリフォールディングするダイナミクスの可視化に成功した。更に、ヘアピンの根元にある不連続サイトを核としてssDNAがアンピーリングする様子や二次構造の形状が時々刻々と変化する様子の可視化にも成功した。これにより、生体フォールディング研究における大きな一歩を踏み出すことができた。I successfully developed high-speed atomic force microscopy combined with optical tweezers via the development of control and analysis software that is capable of synchronous control of these two techniques. Furthermore, I also succeeded in developing a simple method for synthesizing a long-chain hairpin concatemer assay. By means of these newly developed systems, I successfully visualized submolecular-scale unfolding and refolding dynamics of the hairpin structures induced by an external force. The obtained results also indicated that a transitional change of bistable secondary structures over time as well as an unpeeling of ssDNA that is nucleated from a discontinuity at the hairpin construct. These achievements were definitely a giant step in the biological folding research.研究課題/領域番号:19K15409, 研究期間(年度):2019-04-01 – 2021-03-31出典：「高速AFM/光ピンセット複合装置を用いた生体分子の機能動態の解明」研究成果報告書 課題番号19K15409
