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
“Efficacy and tolerability of fesoterodine fumarate in the treatment of overactive bladder symptoms in patients affected by Multiple Sclerosis: Long term follow up”.
No full textfesoterodine fumarate has been already evaluated in the treatment of patients affected by symptoms of idiopathic overactive bladder (OAB)
but no consistent data exist on the effects of the drug in OAB symptoms due to multiple sclerosis (MS). The aim of the present study
was to evaluate the efficacy and tolerability of fesoterodine fumarate in a group of patients affected by MS and OAB symptoms in the long
term follow up.
MATERIAL & METHODS: From October 2009 to September 2011, 20 women and 9 men with MS and symptoms of OAB resistant to other
anticholinergics were included in this prospective study. At baseline all patients underwent voiding diary (every day for one week), MS-specific
quality of life questionnaire (MS-Qol-54) and urodynamics. All patients received fesoterodine fumarate 4 mg once daily. Voiding diary, MSQol-
54 and urodynamics were performed 1 month after the beginning of treatment and then twice a year. Primary endpoints of the study
were: change from baseline in daily frequency of micturitions and urinary incontinence. Secondary endpoint was evaluation of dropout
due to side effects or other problems. Eventual increase in the drug dosage to 8 mg once/daily whenever needed was considered.
RESULTS: Mean ± SD follow-up was 22 ± 1.8 months. At 1 month follow up 22 patients (75.8%) showed a statistically significant
decrease in frequency of micturitions (from 10.6 ± 3.8 to 7.7 ± 2.1; p<0.01) and urinary incontinence (from 1.8±1.7 to 1.2±0.8; p<0.05).
Seven patients (24.1%) withdrew from the study due to adverse events (constipation and xerostomy). In 6 cases (20.6%) an alpha-blocker was added to treatment due to the development of post void residual volume clinically relevant. At 12 and 22 months after treatment, 16/22
patients (72.7%) mantained the reported improvement in urinary symptoms (frequency of daily episodes of urinary incontinence: 0.9 ±
1.0). Six patients discontinued therapy because of the cost of the drug. A global improvement in the QoL questionnaire was observed just at
one month after treatment and was maintained during follow up. Drug dosage was increased to 8 mg once/daily in very few cases.
CONCLUSIONS: The results of this study showed that fesoterodine fumarate 4 mg once daily was effective in the long term follow up of
patients affected by MS and OAB symptoms. The rate of side effects inducing treatment discontinuation was contained and observed shortly
after the beginning of treatment, mostly due to constipations and xerostomy. Interestingly, we noted a high rate of drop-out (27.24%)
during follow up due to the cost of medication. Thus, treatment with fesoterodine fumarate 4 mg once daily is safe and effective in a high
proportion of MS patients with OAB symptoms, but the cost of the drug plays an important role in the discontinuation of therapy
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
