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

Relationships and social influences as predictors of female adolescent condom use
No full textBackground: The study examines how relationship factors such as partner attitude, partner communication, parental communication and social support predict condom use among minority female adolescents. The study sought to determine which factor(s) contributed to greater probability of using condoms. Theoretical frameworks such as Theory of Reproductive Development (Belsky et al., 1991); Theory of Reasoned Action (Ajzen & Fishbein, 1980); Health Belief Model (Rosenstock, 1966) were presented to explain adolescent behavior and condom use. Methods: This study was based on secondary data collected by the Baylor College of Medicine Teen Clinics. A total of 204 (57% African American, 32% Hispanic, and 21% other) female adolescents from southwest part of the United States completed a cross-sectional survey. The study was conducted in the Teen Health Clinics that provide low to free of charge comprehensive family planning and reproductive health services to indigent adolescents who reside in the inner city. Results: Overall, 46% of the adolescents had used a condom the last time they had sex; 54% did not use a condom. There are no differences in age and ethnicity between condom users and nonusers. A significant difference in condom use was observed between those who were currently enrolled in school or graduated, and those who dropped out, with those who were enrolled in school or graduated reporting higher condom use. The findings suggest that two variables, partner communication and partner attitude did distinguish adolescents who used condoms and those who did not. In other words the higher positive partner attitude, the more likely an adolescent is to use condoms, all other factors being constant. Given the same analysis, positive partner communication is shown to be positively associated with condom use. Conclusion: The central issue that cannot be ignored is that adolescents are sexually active, a majority of whom are not using condoms. Partner attitude and partner communications are some of the protective factors found significant. These findings have implications for research and social work practice, particularly for researchers working with adolescent minority females.Social Work, Graduate College o
Moral Hopelessness and HIV/AIDS Global Paralysis
No full textNo disease ever in history, other than the plague of the 14th century, has caused such
serious psychological and emotional distress, affecting families and communities as the AIDS
pandemic. The United Nations AIDS Program (UNAIDS) and the World Health Organization
(WHO) now estimate the number of people living with HIV/AIDS today is 40 million. More than
25 million people have died of AIDS since 1981. At the end of 2007, women accounted for 48%
of all adults living with HIV worldwide, and for 59% of those in sub-Saharan Africa.
Young people (under 25 years old) account for half of all new HIV infections worldwide and
about 6,000 become infected with HIV everyday (UNAIDS/WHO, 2007). Most of the infected
(22.5 million) live in Africa, a continent home to only 10% of the world’s population, but
shouldering over 70% of all cases and 95% of all orphans according to the UNAIDS/WHO
report
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
