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
Differential diagnosis of the pruritus in intrahepatic cholestasis of pregnancy and other specific dermatoses of pregnancy

Republic of Moldova, The 8th International Medical Congress for Students and Young Doctors, September 24-26, 2020Introduction. Pruritus affects up to 20% of pregnant women. Pruritus can be sufficiently
severe to affect sleep and quality of life. Although it is commonly caused by dry skin, it can
also indicate an underlying condition unique to pregnancy. The specific dermatoses of
pregnancy represent a heterogeneous group of pruritic skin diseases that include intrahepatic
cholestasis of pregnancy, pemphigoid gestationis, polymorphic eruption of pregnancy and
atopic eruption of pregnancy. It is important for physicians to be familiar with these conditions
in order to differentiate them for adopting appropriate management of the condition. Aim of the study. This review was undertaken to find the criteria of the differential diagnosis
of pruritus in Intrahepatic cholestasis of pregnancy and other specific dermatoses of pregnancy.
Materials and methods. To identify relevant articles, NCBI and ScienceDirect databases were
searched using the key words: ”pruritus of pregnancy”, “intrahepatic cholestasis of pregnancy”,
“dermatoses of pregnancy”.
Results. This study concluded that even if pruritus is a common sign for all specific dermatoses
of pregnancy, they have some characteristics that make it possible to differentiate them. Were
identified clinical criteria (time of onset, skin lesions character, skin lesions site, association
with primi-/multiparity, association with a family history) and paraclinical ones ( Laboratory
findings, Histopathology, and immunofluorescence). The pruritus of Intrahepatic cholestasis
of pregnancy appear in the second or third trimester, it worsens during the night, skin lesions a
represented by excoriations, papules secondary to scratching that involve palms and soles
followed by rest of the body. Laboratory findings can reveal increased serum bile acids.
Conclusions. The differential diagnosis of the Pruritus in intrahepatic cholestasis of pregnancy
and in other dermatoses of pregnancy is facilitated by clinical criteria such as time of onset,
skin lesions character, skin lesions site, association with primi-/multiparity, association with family history and paraclinical ones: laboratory findings, histopathology, and
immunofluorescence)
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
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
Intrahepatic cholestasis of pregnancy. Diagnosis. Maternal and fetal complications
Get PDFDepartment of Obstetrics
and Gynecology, Nicolae Testemitanu State University of Medicine and Pharmacy, Chisinau,
Republic of Moldova, The 8th International Medical Congress for Students and Young Doctors, September 24-26, 2020Introduction. Intrahepatic cholestasis of pregnancy (ICP) is a cholestatic disorder
characterized by pruritus, elevated serum aminotransferases and bile acid levels with onset in
the second or third trimester of pregnancy, and spontaneous relief of signs and symptoms
within two to three weeks after delivery. ICP has been observed in almost all ethnic groups,
but there is relevant geographical variation in the incidence of ICP varying from less than 1%
to 27.6%. It is important to diagnose it in time because of its effects on pregnancy outcome.Aim of the study. This review was undertaken to find the criteria of diagnosis and to evaluate
the possible maternal and fetal complications.
Materials and methods. To identify relevant articles, NCBI and ScienceDirect databases were
searched using the Key words: “intrahepatic cholestasis of pregnancy”, “Idiopathic jaundice of
pregnancy”, “Pruritus gravidarum”, “diagnosis of intrahepatic cholestasis of pregnancy”,
“outcome on intrahepatic cholestasis of pregnancy”.
Results. This study concluded that Pruritus is the primary clinical symptom of ICP. It usually
presents in the third trimester, after 30 weeks of gestation, but rare cases developing early. The
diagnosis of ICP is based on pruritus of cholestasis, elevated fasting serum bile acids > 10
μmol/L (± and elevated serum transaminases), spontaneous relief of signs and symptoms within
two to three weeks after delivery and absence of other diseases that cause pruritus and jaundice.
Mild jaundice with serum levels of conjugated bilirubin only moderately elevated occurs in 10 to 15% of cases. ICP presents a greater risk to the fetus than to the mother. ICP increases the
rate of preterm delivery with the associated mortality and morbidity, meconium-stained
amniotic fluid. In addition, the fetus seems to be at an increased risk for stillbirth. The major
concern for the mother is for postpartum hemorrhage if her vitamin K level is low, leading to
an increase in prothrombin time. Also women with ICP are more likely to have gestational
diabetes, pre-eclampsia, spontaneous and iatrogenic preterm delivery, with increased rates of
induction of labour.
Conclusions. ICP, especially severe ICP is associated with adverse pregnancy outcome.
Pregnant women should be diagnosed in an efficient time for adopting the appropriate
management to prevent complications as much as possible
