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

No full textThe effect of comorbidities and socioeconomic status on sexual and urinary function in men undergoing prostate cancer screening
No full textIntroduction. Comorbidities and socioeconomic status (SES) represent known confounders of baseline health-related quality of life. Aim. To assess the effect of comorbidities and of SES variables on urinary function (UF) and sexual function (SF) and on associated bother items. Methods. A cohort of 1,162 men without an established diagnosis of prostate cancer (PCa) completed questionnaires addressing SES characteristics, the lifetime prevalence of 12 comorbid conditions, SF and UF as well as their associated bother. Main Outcome Measures. Crude and adjusted logistic regression models tested the association between the predictors, SES and comorbidity, and four separate outcomes, namely SF and UF and their associated bother. Results. Of all men, aged 40-79 years, 172 (14.8%) reported poor or very poor ability to have an erection, and for 165 (14.2%), erectile function (EF) was a big or moderate problem. Daily or weekly urinary incontinence was reported by 98 (8.4%) men, and for 94 (8.1%) men, UF was a big or moderate problem. One or more comorbidities were present in 437 (37.6%) men. In age- and SES-adjusted analyses, major depression and diabetes had the most detrimental effect on EF (5.8 [P < 0.001] and 4.8 [P < 0.001], respectively) and on sexual bother (4.3 [P < 0.001] and 7.2 [P < 0.001], respectively). Stroke (4.7 [P = 0.004]) and drug problems (4.8 [P = 0.002]) had the most detrimental effect on urinary incontinence. Alcoholism and alcohol-related problems (3.1 [P = 0.004]) had the most detrimental effect on the urinary bother scale. Finally, SES only affected urinary incontinence, which was poorer in men who lived with a spouse or partner (2.1 [P = 0.03]). Conclusion. Select comorbidities have very strong effects on UF and EF. Conversely, for most SES variables, the effect was weak and insignificant. In consequence, when patients are assessed for definitive PCa therapy, comorbidities require an adjustment, whereas SES assessment may potentially be omitted, especially if questionnaire brevity is a consideration
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
Impact of chronic prostatitis-like symptoms on the quality of life in a large group of men
No full textObjective To assess the prevalence of chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS) symptoms in a large group of men, using the National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and to evaluate which of the NIH-CPSI symptoms had the most detrimental effect on quality of life (QoL). Subjects and methods The NIH-CPSI was completed by 1273 men during a male-health promotion event. The presence of CP/CPPS-like symptoms was defined according to the NIH-CPSI criteria (perineal pain or ejaculatory pain and NIH-CPSI-pain score >= 4). Finally, using linear regression analyses we evaluated the effect of each questionnaire symptom on the NIH-CPSI-QoL domain. Results The mean (range) age of the men was 57.6 (40-89) years; 133 (10.5%) reported CP/CPPS-like symptoms, with 62 (4.9%) reporting mild and 71 (5.6%) reporting moderate to severe CP/CPPS-like symptoms. Men with CP/CPPS-like symptoms had higher NIH-CPSI-QoL scores, showing a greater detriment of QoL (4.9 vs 2.5; P < 0.001). Of all NIH-CPSI symptoms, urinary frequency was associated with the least favourable QoL, followed by incomplete bladder emptying, pain frequency and pain intensity. The individual pain location had no significant impact on the QoL. Conclusion In a large healthy population CP/CPPS-like symptoms are common and have an important impact on QoL. Functional CP/CPPS-like symptoms have a greater detrimental effect on QoL than pain symptoms. Therefore, these symptoms should represent the main therapeutic targets in affected patients
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
