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
An outline of endocrine disrupting chemicals and the influencing hormones: what the human society ought to know?
Get PDFEndocrine-disrupting chemicals (EDCs) are exogenous chemicals that interfere with hormones action, thereby increasing the risk of adverse health outcomes, including cancer, reproductive impairment, cognitive deficits and obesity. A complex literature of mechanistic studies provides evidence on the hazards of EDC exposure, yet there is no widely accepted systematic method to integrate these data to help identify EDC hazards. Significant advances in research into endocrine-disrupting chemicals (EDCs) and their health effects have elevated concerns in recent years about these chemicals among a number of international scientific and health organizations. The research reviewed here provides knowledge about EDC’s that health scientists can use to inform their research and decision-making processes.

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
Vaccine Hesitancy and Readiness Among University Students: A Cross-Sectional Study
Get PDFBackground: Vaccine hesitancy is a recognized barrier to optimal COVID-19 vaccination coverage, particularly among youth populations. This study examines COVID-19 vaccine acceptance, hesitancy, and associated factors among university students in Southern India, with emphasis on public health policy implications.
Methods: A cross-sectional survey was conducted between June and August 2022 among unvaccinated students at a pharmacy college in Tamil Nadu, India. A structured online questionnaire captured socio-demographic data, attitudes towards COVID-19 vaccination, perceived barriers, and information sources. Chi-square tests and multivariate analyses were applied using IBM SPSS v22, with p<0.05 considered statistically significant.
Results: Of 401 respondents, 346 (87.1%) were unvaccinated; 248 (71.7%) expressed willingness to vaccinate, while 98 (28.3%) were hesitant. Key predictors of hesitancy included inadequate perceived safety information (p=0.047), perception that vaccination is profit-driven (p=0.034), and concerns regarding long-term safety studies (p=0.055). Social media was the dominant information source for hesitant individuals (87.8%). Despite hesitancy, most participants acknowledged vaccination as essential for pandemic control
Conclusion: While in the study, the acceptance rates were high, persistent misconceptions and mistrust highlight the need for targeted information campaigns. Public health policy must address misinformation, strengthen safety communication, and leverage trusted channels to reach student populations.
