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
Delivering contraceptive vaginal rings: Review of postpartum and postnatal care programs in Nigeria
Get PDFPostpartum family planning is a major component of postpartum care services. The Population Council is working to introduce an additional method of contraception in Nigeria—the Progesterone Contraceptive Vaginal Ring (PCVR). The PCVR is administered vaginally but acts systemically to inhibit ovulation. The PCVR contains natural progesterone and is meant for breastfeeding women to augment lactational amenorrhea. As the Council conducts a series of activities as a prelude to eventual introduction of the PCVR in sub-Saharan Africa, including Nigeria, the detailed evaluation of the postpartum program environment is very important. Understanding the prevailing postpartum and postnatal care landscapes will be crucial in determining how best this relatively new contraceptive innovation would be placed within the existing framework. This report reviews the status of various postpartum and postnatal programs in Nigeria, the feasibility of leveraging the ongoing policy, and program opportunities to integrate the PCVR within Nigeria’s post-delivery care environment for the well-being of mothers and their infants
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
Delivering contraceptive vaginal rings—Task sharing policies and practices in the delivery of family planning services: Experiences from Nigeria
Get PDFDespite tremendous progress over the past decades in family planning and fertility reduction, more than 220 million women have unmet need for contraception globally. The government of Nigeria pledged over $11 million to procure contraceptive commodities for distribution in the public sector from 2011–2015, to increase the contraceptive prevalence rate (CPR) that had stalled at 10 percent for almost two decades. The Population Council is facilitating the registration, introduction, and scale-up of the Progesterone Contraceptive Vaginal Ring (PCVR), designed particularly for breastfeeding women, in the sub-Saharan African countries of Kenya, Nigeria, and Senegal. In Nigeria, restrictive policies regarding matching health care cadres with maternal and child health interventions have previously hindered widespread availability of essential commodities to rural areas where providers’ skills were deemed marginal. With the adoption of the national task-sharing policy, which enables lower cadre and community-level providers to deliver essential reproductive health services in hard-to-reach terrains, this report weighs the feasibility of the PCVR to leverage the existing task-sharing platform to achieve large-scale rural uptake, expand the methods mix for postpartum contraception, and contribute to increasing the CPR in this country
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
