Full text linkBackground.Global child disability data are generally non-comparable, comprising different tools, methodologies and disability
definitions. UNICEF and The Washington Group on Disability Statistics (WG) have developed a new tool on child functioning and
disability to address this need.Aims.The aim of this paper is to describe the development of the new module, and to present an independent field test of the
draft module in two contrasting settings.Methods.UNICEF and the WG developed a parent-reported survey module to identify children aged 2\u201317 years with functional
difficulties in population-based surveys through: review of existing documentation, consultation with experts and cognitive
testing. A field test of the draft module was undertaken in Cameroon and India within a population-based survey. Functional
limitation in each of 14 domains was scored on a scale comprising \u201cno difficulty\u201d, \u201csome
difficulty\u201d, \u201ca lot of difficulty\u201d and \u201ccannot do\u201d.Results.In all, 1713 children in Cameroon and 1101 children in India were assessed. Sixty-four percent of children in Cameroon
and 35% of children in India were reported to have at least some difficulty in one or more domain. The proportion reported to
have either \u201ca lot of difficulty\u201d or \u201ccannot do\u201d was 9% in Cameroon and 4% in India. There were no
significant differences in reported functional difficulties by sex but children aged 2\u20134 were reported to have fewer
functional difficulties of any kind compared with older children in both countries.Conclusion.Comparable estimates were generated between the two countries, providing an initial overview of the tool\u2019s
outputs. The continued development of this standardised questionnaire for the collection of robust and reliable data on child
disability is essential.2019-04-30T00:00:00ZPMC64889356242vault:3202
Working with communities to improve their eye health.
Full text linkAs an eye health worker you will be aware of various community interventions for improving eye health. These can involve encouraging people to take better care of their eyes (e.g. specific behaviour change programmes such as encouraging hand and face washing and improving infant feeding practices) and projects that increase the number of people who make use of available services (e.g. encouraging older people to come for cataract surgery, conducting outreach programmes, providing services in the community, or mass drug distribution programmes)

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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
