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
Hypertension and its Association with Socioeconomic Factors in Rural Nepal
No full textBackground: Hypertension is a major risk factor for cardiovascular diseases in all regions of the world. There is an increasing prevalence of hypertension and cardiovascular diseases in developing countries and this is no different in Nepal. Studies from many developed nations have suggested an association between lower socioeconomic status and higher prevalence of hypertension; however, in many developing countries, an association between high socioeconomic status and hypertension has been observed. The increase of hypertension has also been observed in rural areas in Nepal.
Study design: This is a Cross-sectional Study conducted in a primary health facility in rural Nepal.
Purpose: The purpose of this study is to estimate the prevalence of hypertension in a rural village in Nepal, and to determine the association between socioeconomic indicators (income, education and occupation), with hypertension. This has not yet been studied in this area of Nepal and this study will contribute information of prevalence of hypertension and socioeconomic factors in a rural health setting.
Method: This study was conducted among 260 participants at Kirneter health Center located in Dolakha district of Nepal. The study was conducted between October and December 2016. Information on sociodemographic, lifestyle, dietary, and other clinical history of each of the participants was collected using a standardized questionnaire. We measured systolic and diastolic blood pressure 2 times and then calculating each patients’ mean blood pressure as a measure for defining hypertension. Multiple logistic regression models was used to assess association of socioeconomic factors with hypertension.
Results: Prevalence of hypertension was 19.2% in this study. Participants who attained higher education, had higher income and those employed had higher odds of hypertension compared to those with lower education, low income or farmers. However, the result is not statistically significant.
Conclusion: We observed no clear evidence of positive association between higher socioeconomic status and hypertension among patients from Kirnetar health center. Future studies with larger sample size are needed to replicate our findings
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

Tumeric or curcumin and the treatment of knee osteoarthritis: A systematic review and meta-analysis of randomized controlled trials
No full textBackground: The prevalence of knee osteoarthritis (OA) is on the rise globally. This is partly due to the increase in proportion of people aged 60 years and older worldwide. Many of the current therapeutic options for the management of knee OA used in conventional medical practice have undesirable side effects which has led researchers to consider effective and safer alternatives. Curcumin, an herbal medicinal extract from the rhizome – turmeric has a favorable safety profile, and research evidence suggests that it is a viable option for the treatment of knee OA.
Objective: The objective of this systematic review and meta-analysis was to summarize and critically evaluate the published evidence from randomized controlled trials (RCTs) on the efficacy of curcumin in treating knee OA.
Methods: PubMed and Embase were searched for relevant RCTs published up until April 8, 2020. All RCTs that investigated the efficacy or effectiveness of curcumin in treating knee OA were included. Heterogeneity was assessed using I2 statistics, and the random effects models were selected to calculate weighted mean differences (WMD) and mean change differences (MCD) for the outcome measures – visual analog scale (VAS) and Western Ontario and McMaster Osteoarthritis Index (WOMAC) scores.
Results: Ten RCTs (n = 1272) were included in the meta-analysis. Curcumin significantly reduced pain (WMD for VAS (n = 3): -16.76 (-25.41, -8.11), I2 = 87.6%, Pheterogeneity = 1000 mg/d) and type of control (RCTs with curcumin vs. active medication reported effect estimates closer to the null value) contributed significantly to the heterogeneity between the studies. Lastly, the incidence of adverse events was similar between curcumin and placebo but lower in the curcumin group when compared with active controls.
Conclusion: The findings from this review suggests that curcumin is a safe and effective option for treating the symptoms of knee OA. However, the number of RCTs included in the analysis along with their overall quality and the total sample size was not sufficient to draw firm conclusions. Further high quality RCTs with large sample sizes should be conducted in order to provide definitive evidence that allow the adoption of curcumin as a treatment for knee OA in clinical practice
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
