Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
An epidemiological study on HPV prevalence of external genitalia, urinary tract, oropharynx and anus among Japanese men
Get PDF咽頭と尿路のHPV感染の疫学調査では、尿道炎男性患者213例を対象に咽頭うがい液と尿検体を採取し、HPV検出率を検討した。HPV検出率は、咽頭18.3％、尿検体22.1％であった。
次に、一般男性における尿路性器HPV感染率についての疫学調査では、823例の一般健常者を対象、亀頭擦過検体および尿検体HPV陽性率は、亀頭22.8％、尿5.8%であり、尿路に比較し亀頭のHPV感染率が高かった。
最後に、80例のMSM患者(HIV陽性率93%）における肛門・尿路HPV感染の疫学調査では、HPV検出率は肛門検体88.7％、尿検体48.0％であった。男性においてもHPV感染は蔓延していると考えられた。We performed three epidemiological study of HPV infection among Japanese men. One study on ｐrevalence of human papillomavirus infection in the oropharynx and urine among sexually active men showed that HPV detection rates were 18.8% and 22.1% in 213 oral and urine samples, respectively. The prevalence of HPV infection in the oral cavity was similar to that in the urinary tract. Another study investigated HPV infection rates in penile (glans) and urine samples amongh 823 health men. HPV prevalence was 22.8% and 5.8% in penile and urine samples, respectively. HPV infection was more common in penis compared to urinary tract. An additional study demonstrated HPV infections in anus and urinary tract among 80 Japanese MSM (men who have a sex with men) patients. Most of patients (93%) had concomitant HIV infection. HPV infection was detected in 88.7% of anal samples and in 48.0% of urine. These epidemiological studies can support further adaptation for male HPV vaccination in the future.研究課題/領域番号:26861261, 研究期間(年度):2014-04-01 – 2016-03-31出典：研究課題「男性における尿路性器・咽頭・肛門のHPV感染率についての疫学調査」課題番号26861261

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
Etiological role of human papillomavirus infection in the development of urogenital tumor
Get PDF尿路HPV感染を調査する上で最も簡便かつ非浸襲的な方法は、尿検体を使用することと考え、子宮頸癌検診で汎用されている液状細胞診を応用することにより、HPV-PCR検査と細胞診が同時に可能であることを報告した。また、女性膀胱腫瘍84例を対象とした検討では、HPV検出率は6.0%(5例)であった。その5例について、分子細胞学的手法を用いて、感染したHPVが腫瘍の発生に関与していることを示唆し得るデータを得た。同様に日本人陰茎癌の47%がHPV感染に関連したものであったことを突き止めた。Firstly, as urine samples are suitable for large-scale studies of not only HPV but also other microorganisms that cause urethritis because of the ease and noninvasive nature of sampling, we have attempted to improve the analysis methods using urinary samples. We found that this method is applicable for detection of HPV in urine. In addition, eighty-four female patients with primary bladder tumor were studied. HPV-DNA was detected in 5 (6.0%) of 84 eligible patients, and we demonstrated that HPV infection is likely to play an important role in the development of female bladder tumorbased on various histopathological and molecular methods. Furthermore, we found that 47% of penile cancer was likely to be associated with penile HPV infection.研究課題/領域番号:23791748, 研究期間(年度):2011 – 2012出典：研究課題「尿路性器腫瘍に対するヒトパピローマウイルス感染の関連性についての検討」課題番号23791748
