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

No full textVariations 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
Study of socio-economic characteristics, diagnosis and outcome of women participating or not participating in mammogram screening.
No full textBreast cancer is the most common cancer and the leading cause of cancer death in women. Early detection is essential to reduce cancer mortality. Studying participation in an organised breast cancer screening program is important in order to evaluate the program effectiveness. Breast screening both enables minimally invasive breast surgery and reduces cause-specific mortality.The main objective of this study was to evaluate, through the use of a questionnaire, the influence of socio-economic characteristics (age, education, occupational status, participation in other screening programs etc.) on participation in a mammography screening program organized by the local health units (LHU) of Novara and Verbano-Cusio-Ossola, located in the Italian region of Piedmont. A sample of 500 women was identified. Eligible participants included women aged 50-69 years, resident in the area of the LHUs of Novara and Verbano-Cusio-Ossola who had been invited to participate in the screening program 2006-2007. Twenty six women were excluded, leaving 474 women in the final analysis: 23 women were unable to be contacted due to incorrect contact details and 3 women were unable to complete the questionnaire due to neurodegenerative diseases. A postal questionnaire was sent by post during 2008-2009. Two postal reminders were sent to non-responders, followed by a phone call. One group of women received an additional copy of the questionnaire with the first postal reminder and another group received only the reminder letter. The socio-personal profiles and their influence in women's participation in the screening program were evaluated.Among the responders, 93\% of the women (348/374) received a mammogram at least once following LHU invitation for check-up. 74.1\% of women got a mammogram at least once using the organized screening program, an additional 17.8\% got a mammogram in a private clinic, and the type of prevention was unknown for 8.1\% of the women. 25.3\% began having mammogram for prevention before the age of 45.A screening program is a sanitary intervention of secondary prevention and the identification of the attitude towards this kind of prevention is quite complex. Some causes of non-participation in this screening program were the belief that mammogram is not necessary, fear of pain, and presence of family problems. This study obtained a higher response than expected and the data also allowed an assessment of the degree of participation of women in the prevention services, identifying that most of them carried out a mammogram using an organized screening program
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
