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

Pathophysiology evaluation and biomarker development of kidney disease based on saliva and oral microbiota analysis
Full text link腎臓病は依然増加し、併発する他臓器合併症により、生命予後、健康長寿の低下、医療費の増大をきたしている。本課題では、これら腎臓を中心とする全身恒常性の破たんを非侵襲的かつ早期に検出できるバイオマーカーの検索を目的とした。唾液（口腔内細菌）、便（腸内細菌）、血液、尿をサンプルとして細菌叢解析、キラルアミノ酸解析を行い、腎臓病に対する新しいバイオマーカー候補を同定した。今後、特許取得、論文・学会発表を行いバイオマーカーとしての性能を評価しながら臨床への還元を目指す。Currently, kidney disease continues to increase. Complications contribute to poor prognosis, poor health and longevity, and increased medical costs.
The purpose of this study is to identify new early-diagnosis biomarkers for kidney disease.
Using saliva (oral bacteria), stool (intestinal bacteria), blood, and urine as samples, bacterial flora analysis and chiral amino acid analysis were performed. We have identified new biomarker candidates for kidney disease. In the future, we will confirm its usefulness by comparing it with existing biomarkers.研究課題/領域番号:17K08978, 研究期間(年度):2017-04-01 – 2021-03-31出典：「唾液ならびに口腔内細菌叢解析に基づく腎臓病の病態評価とバイオマーカー開発」研究成果報告書 課題番号17K08978

Impact of a specific gut microbiota change on acute kidney injury mice
Full text link本研究課題の目的は、腸内細菌叢と腎臓病の関連を解明し、その成果から腎臓病に対する新たなバイオマーカー候補を同定することである。近年、細菌叢と様々な疾患の関連が注目されている。腎臓病と細菌叢の関連についてもその解明が望まれている。
急性腎障害モデルマウスを作成し、細菌叢の変化を16S rRNA解析により解析し、腎臓害で変化する細菌群を同定した。上記研究成果は、新たな急性腎障害における腸内環境が変化することを示唆している指標として現在、菌の同定とその意義の詳細な検討をすすめている。The aim of this study was to reveal the relationship between gut microbiota and kidney disease and to identify new biomarkers for kidney diseases. The contribution of gut microbiota to various disorders has been reported in recent years. However, the association of gut microbiota with kidney disease remains to be investigated. We revealed the alteration of gut bacteria in acute kidney injury mice with 16S rRNA analysis. This result raise the possibility that gut bacteria could be a new candidate of biomarkers for acute kidney injury. A patent has been applied for the biomarker of kidney injury according to our results.研究課題/領域番号:15K19450, 研究期間(年度):2015-04-01 – 2017-03-31出典：「腸管免疫を介した腎・腸連関機序の解明」研究成果報告書 課題番号15K19450
