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
Research on brain white matter fibers connecting the inferior and superior frontal gyri
Full text link下前頭回と上前頭回を連絡する神経繊維束の存在を疑い、fiber dissectionとMRIによる解析を行った。その結果、本神経線維束の同定に成功するとともに、ブローカ言語中枢と外側上前頭回を連絡する解剖学的特徴を持つこと、左側大脳半球優位な偏在性の性質を持ち男性に強い傾向があること、その所見が弓状束の特徴と共通することから、本線維束が言語ネットワークに関係している可能性が示唆された。またこれらの結果は、術中言語マッピングにおいて外側上前頭回刺激時にみられる発語障害を説明しうると考えられた。The association fibers connecting the inferior and superior frontal gyri were analyzed using fiber dissection and MRI techniques. The fibers were anatomically identified to connect between the Broca center and the lateral superior frontal gyrus, and existed dominantly in left cerebral hemisphere and male population. The anatomical feature was common to that of the arcuate fascicle. These findings suggest a close relationship between this pathway and language organization, and may explain speech disturbances induced by lateral superior frontal gyrus stimulation that were sometimes observed during intraoperative language mapping.研究課題/領域番号:22791338, 研究期間(年度):2010-2011出典：研究課題「下前頭回と上前頭回を連絡する白質神経線維に関する研究」課題番号22791338

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
Development of awake brain surgery for preservation of metalizing
Full text link「心の理論」機能の局在を明らかにするために、覚醒下脳手術を行った右前頭葉グリオーマ15症例において、心の理論タスクによるマッピングデータを収集した。マッピングと機能局在に関して、複数症例において皮質及び皮質下に再現性のある心の理論タスクの遂行困難な領域を確認し、仮説であった心の理論と関連する白質神経線維束Aとの存在が疑われるマッピング結果が得られた。さらに、術前後の経時的な心の理論の検査結果ならびにボクセル単位脳形態学的解析の結果から、右前頭葉手術において白質神経線維束Aが解剖学的に温存された場合、心の理論の維持・改善が期待できることがわかった。From the data of intraoperative mapping using theory of mind task in awake craniotomy for 15 right frontal gliomas, reproducible positive mappings could be confirmed in cortical and subcortical areas, and then overlapped on tractography and standardized brain MRI. A white matter tract "A" was a candidate tract subserving a network of mentalizing because of the three-dimensional distribution of positive mapping on the bundle in tractography and significant relationships between postoperative impairment of mentalizing and resected cavity including the white matter tract A in voxel-based lesion-symptom mapping analysis. This study suggested that structural preservation of white matte tract A would be able to maintain and improve mentalizing postoperatively in the resection of right frontal glioma.研究課題/領域番号:15K19957, 研究期間(年度):2015-04-01 - 2017-03-31出典：「「心の理論」ネットワークの再構築と機能温存を目的とした次世代覚醒下手術法の確立」研究成果報告書 課題番号15K19957

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
