    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    Towards a functioning retail health market : Evaluating the integrated Community Case Management Intervention for Pediatric Febrile Illness in Drug Shops in Rural South Western Uganda

    No full text
    Objectives: This thesis examined the health systems effects of implementing the integrated Community Case Management (iCCM) intervention for paediatric febrile illnesses in a retail health market in South Western Uganda. More specifically, it evaluated drug seller interpretation of malaria Rapid Diagnostics Test (RDT) results (study I), adherence to iCCM guidelines (study II) and the intervention effect on households’ perceived quality of drug seller fever care and care-seeking choice. Study IV qualitatively analysed the iCCM intervention implementation and causal mechanisms for observed effects. Improved understanding of such retail health markets will inform policy decisions and interventions for Universal Health Coverage. Methods: The study used mixed-methods design with an intervention and comparison arm, and pre-test assessment in both study arms. Data collection methods included care-seeker drug shop exit interviews and household surveys using structured questionnaires, focus group discussions, in-depth interviews, review of secondary data and a laboratory analysis of finger-prick capillary blood samples. Results: Among those tested for malaria parasites, there was 93% (95% CI 88.3, 96.2) agreement between drug sellers and laboratory scientist re-reading and with a kappa value of 0.84 (95% CI 0.75, 0.92) (Study I). The drug seller compliance with the reported malaria RDT results was 92.5% (95% CI 87.9, 95.7) (Study I). The iCCM intervention improved appropriate treatment for uncomplicated malaria by 34.5% (95% CI 8.6, 60.4), for pneumonia symptoms by 54.7% (95% CI 28.4, 81.0) and reduced appropriate treatment for non-bloody diarrhoea -11.2% (95% CI -65.5, 43.1), after adjusting for extraneous variables (Study II). Implementing the iCCM intervention in drug shops decreased the odds of households perceiving drug seller fever care as good but increased the household odds of choosing to seek care from private health facilities versus within the community (Study III). Drug sellers operated in a retail market system influenced by knowledge and actions of care-seekers, CHWs, government health workers and regulators, and also how formal and informal rules and norms were applied (Study IV). Implementation of the iCCM intervention at drug shops was modified and shaped by the emerging actor perceptions and behaviours (Study IV). Conclusions: This thesis demonstrates the implementation, causal mechanisms and contextual factors of the iCCM intervention in a rural retail health market. Fidelity and quality of iCCM intervention by drug sellers was acceptably high, probably as a result of co-interventions. Interventions in retail health markets should comprise of components that target the multiple actors or influences that shape that market. Multi-component health system interventions are complex to implement and also create complexity in their evaluation. When technologies are involved, their analysis should go beyond their substance as products and view them as items that encapsulate interests of different actors, some of which maybe converging with or competing against societal goals

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
