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
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
A study of intrauterine fetal death in a tertiary care hospital
Get PDFBackground: Intrauterine fetal death is a major obstetrical complication and a devastating experience for parents as well as obstetricians. If the causes of IUFD can be found, an effective strategy for prevention of IUFD can be formed and maternal complications can thus be prevented. This study aims at identifying the various causes, etiological factors and complications of IUFD.Methods: Prospective observational study was carried out in a tertiary care hospital from 1st January 2016 to 31st July 2017.Results: Total number of deliveries during the study period was 3944 and still birth was 170. Still birth percentage was 4.31.Majority of patient belonged to maternal age group of 21-30 year of age that is 138 out of 170 around 68.5%. Only 8.82% of patients presenting with IUFD were having more than three antenatal visits. Among 61 cases (35.8%) cause was not identified while 109 cases cause was identified. Hypertensive disorder contributed to major cause of IUFD i.e. 34 out of 170 (20%) Maternal complications like hypovolemic shock occurred in 13 out of 170 (7.6%), Acute Renal failure 7 out of 170 (4.11), Sheehan syndrome. Maternal mortality was 3 out of 170 cases.Conclusions: Despite availability of modern interventions like ultrasonography, Non stress test, majority of the causes of IUFD remains unknown. Early diagnosis and delivery is important in cases of IUFD to prevent various complications like septicaemia, acute renal failure, DIC, hypovolemic shock etc
Study of maternal and neonatal outcome in teenage pregnancy
Get PDFBackground: Teenage is a period of transition from childhood to adulthood. According to WHO, the period of teenage extends from 11-19 years. The objective of the present study was to find out the incidence and to evaluate the effect of pregnancy in teenage girls (13-19 years) and its maternal and neonatal outcome.Methods: Prospective observational cohort study, the duration from 1st January 2016 to 31st July 2017.Results: 216 teenage patients were studied; however medical termination and abortions were excluded as the study includes both maternal & neonatal outcome. 3944 pregnant patients were admitted for delivery and abortion related care. Out of this, pregnant adolescents were 216. Proportion of adolescent pregnancy was 5.47%. 170(78.7%) were booked, 32 (14.81%) were unmarried, while 50 (23.1%) were literate. Primigravida were 189 (87.5%) & multigravida was 27 (12.5%).39 (18.05%) were Anemic, Preterm labour occurred in 14 (6.5%) & PROM occurred in 41 (18.9%) patients. Preeclampsia and Eclampsia occurred in 27 (12.5%) and 14 (6.5%) respectively. There were 176(81.48%) normal vaginal deliveries.36 (16.66%) had Lower Segment Caesarean Section; commonest indication being Cephalopelvic disproportion (25%) & 4(1.85%) were instrumental deliveries 53 (24.3%) babies required admission at Neonatal Intensive care unit. Low Birth weight babies were 15 (28.3%).Conclusions: - Early ANC registration and good antenatal care with effective intrapartum & postpartum monitoring along with contraceptive advice on discharge help reduce maternal and neonatal morbidity & mortality associated with teenage pregnancy. However, it is evident that teenage pregnancy rates could be reduced by effective measures like sex education in schools, community-based programs, widespread awareness about contraception
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
