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
Review of the epidemiology of burn injuries in Ethiopia; implications for study design and prevention
Get PDFBackgroundMajority of burn deaths occur in lower and middle income countries where there are limited prevention interventions. Planning and resource allocation for prevention requires consistent and reliable data but published data from these settings are limited in scope and rigor and often not replicable.ObjectiveThe objective of the review was; to examine the literature to determine what information exists on the epidemiology of burn injuries in Ethiopia; to assess its utility for planning interventions for burn prevention.MethodsA broad key term search was performed in Safety Lit and MEDLINE. We reviewed the literature on burn epidemiology in Ethiopia, to assess its utility for planning interventions for burn prevention.ResultsOur search strategy yielded more information than burn specific search strategies. We identified 23 studies drawn from observational and primarily hospital-based, cross sectional studies. They offer preliminary evidence for recommendations for future surveillance, risk factor exploration and prevention initiatives.ConclusionWe conclude that the low rate of burn cases identified from observational studies; the challenge of defining and coding injury in the field; recall bias; mean case series data from hospital data are more efficient and sustainable for monitoring burn epidemiology in Ethiopia. We recommend the establishment of a national trauma registry or WHO’s Global Burn Registry (GBR) to gather data in Ethiopia and countries in comparable settings. Community studies, provide the best avenue to gauge knowledge, attitudes and practices relevant to injury prevention, first aid and health seeking behaviour and to move from research to action that takes the local context into account. This critical preliminary synthesis on burn epidemiology frames future national research and policy on burn surveillance and prevention

No full textThere has been little to no effort on increasing uptake of IUCDs and Implants in Kenya since the 1990s. PSI/Kenya is the first organization in many years to implement a national provider skills building programme promoting quality family planning services, focusing on the longer-term methods of IUCDs and Implants and conducting IPC and mass media interventions to increase correct knowledge of IUCDs and Implants. The purpose of this modified Tracking Results Continuously (TRaC) survey
among women of reproductive age in urban and peri-urban areas of Kenya is to provide evidence for monitoring the implementation of PSI/Kenya's Tunza Family Health Network Program. The data gathered through the 2010 modified TRaC survey will be analyzed according to PSI's Performance Framework and presented in the PSI Research Dashboard. The Dashboard is a set of standardized tables for segmenting populations, monitoring trends on key population and service
delivery indicators, and evaluating program effectiveness.</p
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
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
