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
Performance of a Community-based Health and Nutrition-education Intervention in the Management of Diarrhoea in a Slum of Delhi, India
Get PDFDiarrhoeal infections are the fifth leading cause of death worldwide
and continue to take a high toll on child health. Mushrooming of slums
due to continuous urbanization has made diarrhoea one of the biggest
public-health challenges in metropolitan cities in India. The objective
of the study was to carry out a community-based health and
nutrition-education intervention, focusing on several factors
influencing child health with special emphasis on diarrhoea, in a slum
of Delhi, India. Mothers (n=370) of children, aged >12-71 months,
identified by a door-to-door survey from a large urban slum, were
enrolled in the study in two groups, i.e. control and intervention. To
ensure minimal group interaction, enrollment for the control and
intervention groups was done purposively from two extreme ends of the
slum cluster. Baseline assessment of knowledge, attitudes, and
practices on diarrhoea-related issues, such as oral rehydration therapy
(ORT), oral rehydration salt (ORS), and continuation of breastfeeding
during diarrhoea, was carried out using a pretested questionnaire.
Thereafter, mothers (n=195) from the intervention area were provided
health and nutrition education through fortnightly contacts achieved by
two approaches developed for the study-'personal discussion sessions'
and 'lane approach'. The mothers (n=175) from the control area were not
contacted. After the intervention, there was a significant (p=0.000)
improvement in acquaintance to the term 'ORS' (65-98%), along with its
method of reconstitution from packets (13-69%); preparation of
home-made sugar-salt solution (10-74%); role of both in the prevention
of dehydration (30-74%) and importance of their daily preparation
(74-96%); and continuation of breastfeeding during diarrhoea (47-90%)
in the intervention area. Sensitivity about age-specific feeding of ORS
also improved significantly (p=0.000) from 13% to 88%. The reported
usage of ORS packets and sugar-salt solution improved significantly
from 12% to 65% (p=0.000) and 12% to 75% (p=0.005) respectively. The
results showed that health and nutrition-education intervention
improved the knowledge and attitudes of mothers. The results indicate a
need for intensive programmes, especially directed towards urban slums
to further improve the usage of oral rehydration therapy

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
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
