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
Measuring Disability in Population-Based Surveys: The relationship between clinical impairments, self-reported functional limitations and equal opportunities in two Low and Middle Income Country settings
Full text linkBackground: Measuring disability in population-based surveys is imperative to support the meaningful inclusion of persons with disabilities in their societies. Disability is a complex bio-psycho-social phenomenon incorporating dysfunctioning in any of three interlinked levels (impairments in body function or structure, activity limitations or participation restrictions), resulting from the interaction between a health condition and contextual factors. There is little consensus on how to measure different components of disability in population-based surveys, or how these components inter-relate. A comprehensive population-based methodology is needed to be able to assess the prevalence and lived experience of disability, incorporating the three levels at which dysfunctioning occurs. Study Aim: To develop and undertake a comprehensive population-based survey methodology of disability in two settings and i) use this to explore the inter-relationship between tools measuring different components of disability ii) assess the prevalence and iii) lived experience of disability, including predictors of inclusion. Methods: A scoping review of the literature was undertaken to inform the development of an all-age population-based survey of disability. Population-based surveys (n=4080) of disability incorporating measures of impairment (vision, hearing, musculoskeletal, depression), activity limitation (Washington Group Extended Set) and participation restrictions (SINTEF participation module) were undertaken in one district each of Cameroon (North West Region, 2013) and India (Telangana State, 2014). A nested case-control study of people with and without disabilities was undertaken, to identify predictors of inclusion (e.g. access to health and rehabilitation, education, livelihoods). Key Findings: Overall disability prevalence was 12.2% (India) and 10.5% (Cameroon). Approximately 40% of people in each setting who screened positive for a clinical impairment did not report a functional limitation. A self-reported functional limitation tool followed by clinical screening of all those who report any level of difficulty would identify 94% of persons with disabilities in Cameroon and 95% in India, meeting the study criteria. Persons with disabilities in both settings experienced unequal opportunities. Children with disabilities were at least ten times less likely to be enrolled in education than children without disabilities; whilst adults with disabilities were five times less likely to be working than adults without disabilities, and between twice (Cameroon) and three times (India) more likely to have experienced a significant health problem in the past year. Conclusion: This study provides a suggested way forward for the measurement of disability in population-based surveys that would support the meaningful inclusion of persons with disabilities in their societies
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
The Nakuru Eye Disease Cohort Study
Full text linkObjective: To provide six-year cumulative incidence of visual impairment and
blindness, diabetic retinopathy (DR), age related macular degeneration (AMD),
visually impairing cataract and features of glaucoma in an older age Kenyan
population and the risk factors for each.
Design: Population based cohort study with six-year follow-up (n=2,171; 50%
participation)
Main outcome measures: Six-year cumulative incidence of visual impairment and
blindness, DM, DR, AMD, visually impairing cataract and features of glaucoma, risk
factors for incidence and population estimates.
Results: The six-year cumulative incidence of visual impairment and blindness was
119.4 (103.1 - 137.9) and 15.1 (10.4 – 21.7) per 1000 of population respectively.
The six-year cumulative incidence of DM and DR (in those with diabetes mellitus)
was 61.0 (50.3 - 73.7) and 224.7 (116.9 - 388.2) per 1000 of population respectively.
The six-year cumulative incidence of AMD was 164.2 (136.7 - 195.9) per 1000 of
population and the six-year cumulative incidence of visually impairing cataract was
235.6 (213.5 – 259.3) per 1000 of population. Associations with incident cases were
demonstrated for each with age and diabetes being the leading associations across
the primary outcome measures.
Conclusions: This six-year follow-up of a population-based cohort indicates a high
incidence of visual impairment and blindness and provides data, for the first time, on
the incidence of DR, AMD and cataract in Kenya. A large gap exists between
provision and need for services and cataract control should remain the priority focus
with work to strengthen health care systems as posterior segment eye diseases will
become a greater issue as services improve and cataract comes under greater
control
