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
Awareness, Attitude and Willingness of Artisans in Osun State Southwestern Nigeria to Participate in Community Based Health Insurance
Get PDFIntroduction: Community Based Health Insurance Scheme was recently launched in Nigeria with a view to reducing the burden of out-of-pocket expenditure on health most especially among Nigerians in the informal sector. The objective of this study is to assess the awareness, attitude and willingness of artisans in Osun state to take part in Community based health insurance scheme in Nigeria.Methods: Descriptive cross sectional survey of 387 artisans in Osun state in South-western Nigeria. Respondents were selected using multi stage sampling method. Research instruments were semi structured interviewer administered pre tested questionnaires that was divided into five sections. Data was analysed using the SPSS software.Results: Mean age of the artisans was 33.1 ± 11.2 years. One hundred and twenty six (76.4% ) of those who always visit the hospital when ill) used out of pocket as their form of health care financing. One hundred and twelve (28.9%) of the respondents have heard of health insurance before. Only fifteen (3.9%) of the artisans had been on any forms of Health Insurance, of which 13(86.7%) were on the National Health Insurance Scheme (NHIS). Twenty five (6.5%) of artisans had heard of community health insurance before and only 2(0.5%) were enrolled in a form of Community Based Health Insurance (CBHI). Most of the respondents (319; 82.4%) were willing to participate (WTP) in Health Insurance with the preferred organizer being governmen (236; 74.0%). The mean amount of money respondents were willing to contribute monthly per household was 1,121.8 ± 14.04 Naira. There was a statistically significant relationship between awareness about CBHI and educational status (p=0.003), and between WTP in health insurance and monthly income (p=0.014). The amount respondents were willing to pay monthly for health insurance was found to be significantly associated with their monthly income (p<0.001) and their educational status (p<0.001).Conclusion: Artisan's awareness about CBHIS is low. Most artisans showed favourable attitude towards participating in a Government backed and well organised scheme, as well as a good attitude towards willingness to pay in the scheme.Keywords: Artisans, CBHIS, willingness to pay (WTP), Health Insuranc
Prevalence And Risk Factors For Human Pappiloma Virus Infection Among HIV Positive Pregnant Women In Urban Slums Of Osogbo, Nigeria.
No full textHuman Pappiloma Virus (HPV) infection is a disease of global public health importance, culminating into a high risk of cervical cancer. Most of the risk factors are modifiable, thus making HPV itself preventable. Efforts towards community HPV prevention and vaccination have not yielded the desired results, most especially in the face of co-infection with HIV.This study assessed prevalence and risk factors for HPV among HIV positive pregnant women in Osogbo, Nigeria. Descriptive cross sectional study among pregnant HIV positive women of reproductive age selected using simple random sampling method. The IgG antibody tests to HPV were conducted using standard methods. Research instruments were semi structured interviewer administered questionnaire. Data was analyzed using the SPSS soft-ware version 17.0. Mean age of respondents was 33.0+2.1 years. Twenty seven (28.0%) were aware of HPV as a genital infection, while 7.1% of respondents had a positive HPV results and 92.9% HPV antibody test negative. Sexual risk score was high among 28(29.0%) of respondents while no respondent had gone for a HPVvaccination. Respondents with high sexual risk score were three and a half times more likely to have a positive HPV results compared to those with lower risk score (OR 3.6, 95%CI 0.740-1.706, p-0.066). Poor awareness, low prevalence of HPV, some level of high sexual risk behaviour and no record of HPV vaccination characterized the women studied, and these observations call for sustained communityawareness programmes to reverse these trends
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
