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
Variation in health system performance for managing diabetes among states in India:a cross-sectional study of individuals aged 15 to 49 years
Full text linkBackground: Understanding where adults with diabetes in India are lost in the diabetes care cascade is essential for the design of targeted health interventions and to monitor progress in health system performance for managing diabetes over time. This study aimed to determine i) the proportion of adults with diabetes in India who have reached each step of the care cascade, and ii) the variation of these cascade indicators among states and socio-demographic groups. Methods: We used data from a population-based household survey carried out in 2015 and 2016 among women and men aged 15 - 49 years in all states of India. Diabetes was defined as a random blood glucose (RBG) ≥200mg/dl or reporting to have diabetes. The care cascade – constructed among those with diabetes – consisted of the proportion who i) reported having diabetes (‘aware’), ii) had sought treatment (‘treated’), and iii) had sought treatment and had a RBG <200mg/dl (‘controlled’). The care cascade was disaggregated by state, rural-urban location, age, sex, household wealth quintile, education, and marital status. Results: 729,829 participants were included in the analysis. Among those with diabetes (19,453 participants), 52.5% (95% CI, 50.6% - 54.4%) were ‘aware’, 40.5% (95% CI, 38.6% - 42.3%) ‘treated’, and 24.8% (95% CI, 23.1% - 26.4%) ‘controlled’. Living in a rural area, male sex, less household wealth, and lower education were associated with worse care cascade indicators. Adults with untreated diabetes constituted the highest percentage of the adult population aged 15 to 49 years in Goa (4.2%, 95% CI, 3.2 % - 5.2%) and Tamil Nadu (3.8%, 95% CI, 3.4% - 4.1%). The highest absolute number of adults with untreated diabetes lived in Tamil Nadu (1,670,035, 95% CI, 1,519,130 - 1,812,278) and Uttar Pradesh (1,506,638, 95% CI, 1,419,466 - 1,589,832).Conclusions: There are large losses to diabetes care at each step of the care cascade in India, with the greatest loss occurring at the awareness stage. While health system performance for managing diabetes varies greatly among India’s states, improvements are generally particularly needed for rural areas, those with less household wealth and education, and men. Although such improvements will likely have the greatest benefits for population health in Goa and Tamil Nadu, large states with a low diabetes prevalence but a high absolute number of adults with untreated diabetes, such as Uttar Pradesh, should not be neglected.

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
The prevalence of concurrently raised blood glucose and blood pressure in India:a cross-sectional study of 2,035,662 adults
Full text linkObjective: In order to inform integrated, person-centered interventions, this studyaimed to determine the prevalence of having both a raised blood glucose (BG) andblood pressure (BP) in India, and its variation among states and population groups.Methods: We pooled data from three large household surveys (the AHS, DLHS-4, andNFHS-4), which were carried out between 2012 and 2016 and included adults aged≥15 years. Raised BG was defined as having a plasma glucose reading ≥126 mg/dl iffasted and ≥200 mg/dl if not fasted, and raised BP as a systolic BP ≥140 mmHg ordiastolic BP ≥90 mmHg. The prevalence of having a concurrently raised BG and BP(‘co-morbid’) was age-standardized to India’s national population structure, anddisaggregated by sex, age group, BMI group, rural-urban residency, household wealthquintile, education, state, and region.Results: The age-standardized prevalence of the co-morbidity was 1.5% (95% CI, 1.5-1.5), varying by a factor of 8.3 between states. Among those aged ≥50 years, 4.5%(95% CI, 4.3-4.7) with a BMI<23.0kg/m2 and 16.1% (95% CI, 15.0-17.4) with a BMI≥30kg/m2 were co-morbid. Age, BMI, household wealth quintile, male sex, and urbanlocation were all positively associated with the co-morbidity.Conclusions: A substantial proportion of India’s population had both a raised BG andBP, calling for integrated interventions to reduce CVD risk. We identified large variationamong states, age groups, and by rural-urban residency, which can inform healthsystem planning and the targeting of interventions, such as appropriate screeningprograms, to those most in need
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
