    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Community determinants of health care seeking for tuberculosis : the role of socio-cultural determinants and gender in Tanzania

    Full text link
    The WHO End TB strategy targets to end the global tuberculosis epidemic by 2035 with a reduction of 90% new cases, a 95% reduction in deaths, and to ensure that no family is burdened by catastrophic costs as a result of tuberculosis. In order to reach this ambitious goal, not only strengthening of tuberculosis control programs, discovery, development and evaluation of novel and sensitive tuberculosis diagnostics tools will be required, but also actions with regard to social determinants of tuberculosis and health care seeking, particularly in low-income settings with high tuberculosis burden. Furthermore, novel and more sensitive TB diagnostics tools will only have an impact at the population-level if the millions of undiagnosed TB cases reach health care centres timely for diagnosis and treatment. The low tuberculosis case detection observed in Tanzania and elsewhere is not only due to limitations in tuberculosis diagnostics, but also in the socio-cultural and economic factors which are relevant for tuberculosis healthcare seeking, timely diagnosis and treatment. This doctoral thesis therefore aimed to assess the pathways and costs of care from the onset of tuberculosis symptoms, to explain patient and diagnostic delays and loss to diagnostic follow-up during health care seeking, and finally to explore the role of traditional healers in tuberculosis management and control in Tanzania, using quantitative and qualitative methods. It firstly makes use of data obtained from the on-going tuberculosis cohort study in Dar es Salaam Tanzania, interviewing 100 confirmed and 100 presumptive tuberculosis patients on pathways to care and on direct and indirect costs, with data recording on tablets using the OpenDataKit (ODK) application. Secondly, data were collected during an intervention study on intensified case findings at pharmacies in Tanzania, administering a semi-structured explanatory model interview based on the EMIC framework for cultural epidemiology to 136 presumptive and confirmed TB patients. It further used data from in-depth interviews and structured interviews with 90 traditional healers in urban, peri-urban and rural districts of Tanzania. Pathways to care in confirmed tuberculosis patients were complex compared to the presumptive patients. In confirmed patients, pathways involved several visits to health care facilities before diagnosis, while that of the presumptive patients were more direct with only one or few visits to healthcare facilities before diagnosis. Confirmed and presumptive TB patients spent a median of 31% of their monthly household income on health expenditure for all five visits to healthcare facilities. Indirect costs were considerably higher than direct costs both in confirmed and presumptive TB patients. A patient delay of ≥3 weeks was observed in almost two thirds of our participants from the intervention study. In addition, loss to diagnostic follow-up was observed in 44.1%. Prior consultations with traditional healers were associated with patient delay but not with loss to diagnostic follow-up. Gender differences were observed in patient delay and LDFU, whereby the odds of patient delay were higher in females than in males, and also loss to diagnostic follow-up was higher in females than in males. Knowledge on cough and tuberculosis related symptoms was limited among traditional healers and varied in urban, peri-urban and the rural settings. Costs spent for traditional healers for treatment of cough and tuberculosis symptoms were lower than costs incurred by patients from the formal healthcare providers. Traditional healers in all three study sites referred patients for further treatment. Collaboration among the traditional healers, the government (NTLP) and other stakeholders was limited. There was a significant association between collaboration with the government and referring patients to hospitals for further treatment. The results from this PhD project contribute to our understanding on the pathways and costs of care in confirmed and presumptive tuberculosis patients. This study is among a few to report costs associated with tuberculosis taking into account gender differences and poverty status. Furthermore, it contributes to open questions regarding patient delay and loss to diagnostic follow-up during healthcare seeking. Our study is also among the few to address the gap on the role of traditional healers in tuberculosis management particularly from sub-Sahara Africa. Given the importance of tuberculosis in terms of global disease burden, and the WHO’s ambitious goal to end tuberculosis by 2035, planning and specific interventions which integrate social and biomedical solutions are needed

    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

    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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
