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
The impact of rheumatic diseases in Iraq on pregnant women whose ages range from (25-35 years)
Get PDFRheumatoid arthritis (RA) is a chronic, recurrent inflammatory autoimmune condition characterized by persistent inflammation of the synovial joints, which over time and especially without intensive treatment, leads to erosive development, with the destruction of the articular cartilage and complete loss of joint integrit
Evaluation of the Outcomes of Hypothyroidism in Pregnant Women
No full textBackground: Hypothyroidism may also affect the safety of pregnancy and the health of the fetus, such as the occurrence of miscarriage, premature birth, the effect on the mental development of the fetus, and high blood pressure during pregnancy. Based on previous studies, changes in thyroid function are more common in women, with some considering a 10:1 ratio compared to men. Within it, hypothyroidism occurs at a rate of 0.5-2.5% of all pregnancies, while subclinical hypothyroidism has a prevalence of 2-2. 5% in pregnant women. Between 5-9% of patients develop thyroid disease after birth. Objective: This study aims to Evaluate of the outcomes of hypothyroidism in pregnant women. Patients and Methods: A descriptive cross-sectional study was conducted for the evaluation of the outcomes of hypothyroidism in pregnant women from 4th February 2020 to 8th October 2021. this study was applied to 90 patients in different hospitals in Iraq. In this study, the patients were divided into two groups; the first was hypothyroidism which included 50 patients, while the second group included the control, which included 40 patients by using the SPSS program. Results and Discussion: The results of the study showed a convergence between control patients in terms of age, where the highest percentage was set for ages between 25-34. This study showed an increase in BMI, where the cases were identified as 35 ± 2.5 for patients and 28 ± 3.1 for control with a p-value of 0.0486. According to the economic level, our study showed that most of the patients were from the middle class and included 22 (44%) for patients, and 19 (47.5%) for control, with a p-value of 0.0431. In addition, An assessment was made for pregnant women with hypothyroidism and control, which included percentage and frequency, and the Apgar rating score did not show a wide difference between patients and control. Conclusion: In this study, we identified a statistically significant association between the incidence of problems in pregnant women with hypothyroidism, with a weak correlation between the control group and the frequency of difficulties. In the first group, a high association with the occurrence of complications was discovered, less than or equal to 0.05
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
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
