    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

    The overall objective of this thesis is to investigate factors that influence the utilization of maternal services, infant feeding and postpartum contraception practices in rural Vietnam. Field studies were carried out in a rural district of Thanh Hoa, a province located in North Central Vietnam. Willingness-to-pay for maternal preferences was measured in a sample of 200 postpartum and 196 pregnant women, as well as 196 men using the payment card technique. An association was found between satisfaction with the quality of maternal services and willingness-to-pay. There were no significant differences in willingness-to-pay values between prenatal and postpartum groups, and between male and female subjects. The feasibility, reliability and validity of a 20-item scale for measuring perceived quality of maternal services provided at commune health centres, were examined based on a sample of 200 postpartum and 196 pregnant women. The instrument was found to have good inter-rater reliability and internal consistency. Maternal status of clients (prenatal vs. postnatal) was found to influence the perceived quality of maternal services. Determinants of the utilization of maternal services at the primary health care level were investigated in a sample of 200 postpartum women together with sixteen focus group discussions and 16 in-depth interviews. The results showed that client-perceived quality of services and socio-cultural, and economic factors, rather than geographical access, could affect the utilization of maternal services. Factors affecting infant feeding practices were measured in a longitudinal study of 463 women at weeks one, 16 and 24 postpartum. Within the first week after delivery, the initiation and exclusive breastfeeding rates were relatively high at 98.3% and 83.6% respectively, but the premature introduction of complementary food was a great concern.Exclusive breastfeeding dropped from 83.6% at week one to 43.6% at week 16, and by week 24, no infant was exclusively breastfed. Home-cooked solid food was introduced by 4.8%, 40.9% and 74.3% at weeks one, 16 and 24, respectively. Logistic regression analysis showed that, together with socio-cultural determinants, factors related to the mother, such as education level and occupation, and infant related factors could influence the initiation and exclusive breastfeeding within six months postpartum. The practice of contraceptive use within six months postpartum was also examined in a prospective study of 463 postpartum women. The proportion of contraceptive users at weeks 16 and 24 were 17.4% and 43.4% respectively. At week 24, of contraceptive users, 57.3% used IUD, 25.1% used condom, and 13.6% used traditional methods. Logistic regression analysis found age, sufficient knowledge on contraceptives and husband/partner opinion can significantly affect the contraception decision. The results of the study indicated that good physical access does not necessarily increase the utilization of maternal services due to institutional, environment and individual barriers. Client-perceived quality of services, socio-cultural and economic factors are important determinants of the utilization of maternal services. In view of the observed low rates of exclusive breastfeeding and contraception, there is a risk of unwanted pregnancy for women within six months postpartum. To improve maternal and child health status, health workers need to be trained in terms of inter-personal communication and counselling skills, and be appropriately supervised by district health authorities. Mobilizing the participation of the community and family, especially men to share the workload with women, would play a crucial role in the improvement of childbirth, contraception and breastfeeding practice

    Appropriate Similarity Measures for Author Cocitation Analysis

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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.
