    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

    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

    Clients' returning for cervical screening results : a focus group study exploring the reasons why women spontaneously return for their results at the Khayelitsha Cervical Cancer Screening Project

    No full text
    Bibliography: leaves 112-123.Cervical cancer is integrally associated with the problems of poverty in the developing world. It is the most common cancer cause of death among women in these regions. In South Africa, the lifetime risk for black African women developing this cancer is 1 in 26. Rates for white women are 1 in 80. Cervical cancer is largely preventable by screening for its precursor stages. However, cervical cancer screening in low-resource settings has only rarely been initiated and sustained. There are many barriers to the establishment of mass, organised screening programmes. This study focuses on one aspect of the screening process: the clients' receiving of their screening results. For the most part, health providers in resource-poor settings rely on the clients themselves to return to the health service to receive their results and consequent arrangements for further care. Understanding those factors that impact upon clients' returning is therefore crucial to the success of the screening. The Khayelitsha Cervical Cancer Screening Project (KCCSP) was established in 1996 to evaluate alternative screening tests to cytology. In addition, the Project has evaluated alternative screening algorithms to the traditional approach of cytology, colposcopy, biopsy and treatment, specifically, a "screen and treat" approach. This approach is expected to overcome some of the many barriers to women participating in screening programmes. This study aims to investigate the phenomenon of the high spontaneous return rate in the setting of the KCCSP. Motivating and deterring factors are sought, both logistical and psychological, in the clients' personal contexts, as well as those related to their experiences of the Project. Exploratory study in the interpretive research paradigm located in a peri-urban informal settlement outside Cape Town, South Africa. Volunteer sample of women enrolled in the KCCSP returning for their first set of screening results. Four focus groups were conducted in Xhosa, facilitated by a Xhosa-speaking social worker from Khayelitsha who has experience in focus group work. Discussion guidelines were followed. The discussions were tape recorded and later transcribed before being translated into English by the facilitator. Analysis of the data draws on elements of both the grounded theory and the systems theory paradigms. The findings reveal that, for the most part, women present to the KCCSP in order to have general gynaecological problems addressed. Returning for results represents an extension of this need. Obstacles to returning include problems with access to the clinic, the need to care for dependents at home and the competing priorities of housework and generating income. Factors that promote the returning for results are the imperative to understand the cause of, and have treatment for pre-existing gynaecological symptoms which cause high levels of anxiety. Related to this, women are motivated to have confirmed or refuted the diagnosis of a fatal disease, including cancer and HIV. Certain qualities and design features of the KCCSP facilitate women returning fOr their results. These include the perceived superior quality of interpersonal communication between Project staff and clients and the efficient manner in which results are made available to clients. Other promotive or obstructive factors that playa role in cervical screening service utilisation include; client attitudes towards traditional healers, a prevalent fear of hysterectomy, concern about privacy and gossip and a suspicious attitude toward caring health workers. Women enrolled in the KCCSP have a personal health agenda with a different focus to that of the Project. Chronic gynaecological problems are frequently experienced and give rise to levels of anxiety about their being signs of serious pathology. Women have not had these fears or the symptoms adequately addressed at other health services. The need to have these issues properly managed represents a large enough motivating force to overcome many of the practical and psychological obstacles to utilisation of the KCCSP. The Project represents for women a general women's health service

    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
