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
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
Essays on Children\u27s Well-being: Impacts of Policies and Approaches to Measurement
No full textThis dissertation explores socioeconomic issues related to children’s well-being in developing countries. The first essay examines the effect of the Lord’s Resistance Army insurgency on children’s health using the 2011 Uganda Demographic and Health Survey. The distance from each village to the border of South Sudan is used as an instrument for identifying the intensity of the conflict. We find that each conflict event in a village lowers weight-for-age and weight-for-height z-scores for children born after the conflict. We further investigate possible heterogeneous conflict effect on child health in terms of gender, region, and maternal education. Low household assets, limited access to health care, and poor maternal nutrition appear to be channels through which the conflict inhibits the growth and development of children five years after the end of the conflict. The second essay investigates associations between transitions in monetary and multidimensional poverty using the 2006 and 2009 Young Lives surveys in Ethiopia, India, Peru, and Vietnam. While the headcount ratio in both measures of poverty decreases over time, there is only a limited overlap between the groups in monetary and multidimensional poverty in either or both waves. Children remaining in monetary poverty are more likely to stay in multidimensional poverty. However, children escaping from monetary poverty do not always exit from multidimensional poverty. The results suggest the need to go beyond traditional monetary poverty indicators to understand and monitor poverty dynamics among children. The third essay evaluates the impact of Health Care Fund for the Poor (HCFP) on healthcare utilization, health expenditure, and the health and education outcomes using the 2009 Vietnam Young Lives Survey. We find that HCFP beneficiaries are more likely to increase the use of inpatient and outpatient medical care compared to households with no health insurance while their health expenditure is not statistically different from each other in the young cohort. No effect of the program is found in the older cohort. The overall results suggest that the free health insurance program may improve healthcare utilization for households with young children
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

Social engagement and health in an aging society: Impact of Basic Old-Age Pension in Korea
No full textDespite older people\u27s notable contributions to economic growth in Korea, a significant proportion of them were left financially unprepared for old age and faced a high risk of poverty after retirement. In 2007, the National Pension was reformed to gradually lower the income replacement ratio from 60 % to 40 %. The Korean government implemented the Basic Old-Age Pension (BOAP) to compensate for the loss in pension income in 2008. While the BAOP benefits mitigate income poverty, it may also have spillover effects on social activities and health outcomes that older people are likely to be deprived of. We use the 2006–2020 Korean Longitudinal Study of Aging for the analysis. Using a doubly robust difference-in-differences model and event study, we investigate the impact of BOAP on social engagement and the health of older people. The results show that BOAP recipients tend to have more frequent meetings with children and are likely to have a better relationship with children while they are less likely to participate in social groups and have fewer social group meetings. These results are more evident among those recipients who have received pension benefits for longer years. We find a greater positive impact of BOAP on the health of non-employed, non-married, and poor recipients and the social activities of women, employed, and non-poor recipients. The impact of BOAP may vary by gender, employment status, marital status, and poverty status but the overall results emphasize the continual assistance of BOAP in promoting the social engagement and health of older Koreans. © 2025 Elsevier B.V., All rights reserved
