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
Benzydamine hydrocloride: severe intoxication in a 4-years-old-child
No full textINTRODUCTION: Benzydamine hydrocloride (BHC) is a nonsteroidal anti-inflammatory drug used for the
symptomatic treatment of oropharyngeal, gynaecological and musculoskeletal inflammatory conditions(1).It’s
available as powder to be dissolved in water for the topical treatment of non specific vaginitis and
vulvovaginitis in children, adolescents and adults. Sistemic absorption after local use is low, while BHC is
quickly absorbed after oral administration.According to the literature 64% of an oral dose is absorbed by 1
hour and it is completed in 4-6 hours (2).Fifty-five percent of the dose is excreted in urine while the remaining
part is metabolized by the liver.
Acute BHC poisoning is associated with gastrointestinal symptoms(abdominal pain, nausea and vomiting)
and neurological disorders(agitation, hallucinations, delirium and seizures). Administration error was reported
as the most important cause of overdose(1). We reported a case of BHC poisoning due to an incorrect
accidental administration of the drug.
CASE REPORT: A previously healty 4-years-old-girl was brought to our Emergengy Department because of
severe agitation, tremors and choreiform movements associated with visual hallucinations (she mentioned to
see ticks and rabbits). BP was 123/68 mmHg, RR was 30 breaths/min, SO2 96%. The child presented
hyperemia of the perioral area, no fever, no vomiting. Cardiac, pulmonary and abdominal examination was
normal. No signs of meningism were present. Complete blood count, serum electrolytes, coagulation
parameters, renal and liver function tests were normal.
She was initially treated with diazepam i.v. unsuccessfully, then she received sedation with propofol, fentanyl
and midazolam for 24 hours. After 30 hours from admission she was alert and the hallucinations were
resolved.
The day before the child was seen by her pediatrician because of dysuria and oral Fosfomycin plus a vaginal
douce preparation of 500 mg BHC (powder to be dissolved in 500 ml of water) were prescribed. Seven hours
before admission, by mistake, her grandmother gave her the topical preparation orally, in 100 mL solution.
The calculated oral ingested dose of BHC was about 30 mg/kg. The intoxication was confirmed by the
presence in urine of benzydamine(1,10 microg/mL). DISCUSSION: Several cases of BHC overdose have been described in the literature at all ages.
In most of them BHC was mistaken for an oral preparation (1,2,3), as in our case, less frequently it happens
for accidentally ingestion, seldom with suicidal intention (4) or for recreational use as hallucinogen.
A recent study(2) confirmed a relevant number of cases in Italy and highlighted also the important role of
television advertising about the correct and safe use of BHC in Italy.
Considering the wide use of BHC-containing gynaecological preparation in our Country we still suggest that
if a patient is presented with visual hallucination and agitation, oral administration should be considered
