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
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

Changes in City-Level Foreclosure Rates and Home Prices through the Great Recession and Depressive Symptoms among Older Americans
Get PDFpeer reviewedThe changing economic fortunes of cities influence mental health. However, the mechanisms through which this occurs are underexplored. I address this gap by investigating the Great Recession of 2007-2009. Using the National Social Life, Health, and Aging Project survey (N = 1,341), I study whether rises in cities’ home foreclosure rates and declines in median home prices through the Great Recession increase older persons’ depressive symptoms. I also study possible mediation through household assets declines. I find that increases in cities’ home foreclosure rates and declines in median home prices increase depressive symptoms beyond the effects of personal financial losses. Results show no evidence of mediation through asset loses, suggesting effects through other channels. Supplementary analyses reveal less direct links between changes in city-level unemployment rates and median household incomes and changes in depressive symptoms
Conditional on the Environment? The Contextual Embeddedness of Age, Health, and Socioeconomic Status as Predictors of Remote Work among Older Europeans through the COVID-19 Pandemic
No full textCOVID-19 era lockdown measures resulted in many workers performing their employment
tasks remotely. While identifying individual-level predictors of COVID-19 era remote work,
scholarship has neglected heterogeneity based on contextual characteristics. Using the first
COVID-19 module (2020) of the Survey of Health, Ageing and Retirement in Europe (N = 8,121)
and multinomial logistic regression analyses, this study examined how country-level digitalization,
stringency of government COVID-19 containment measures, and COVID-19 era excess mortality
moderated how individual-level age, health, education, and income affected working partly or fully
remotely among older Europeans (50-89 years) continuing to work through the pandemic. The
central findings are that higher societal digitalization reduced the positive association between
education and fully remote work, and greater country-level excess mortality accentuated how
more education and poorer health increased the probability of fully remote work. These findings
are interpreted through the fundamental cause theory of health and the health belief model. They
further lead to recommendations that during future epidemics, policies and programs should
address the remote working capabilities of older persons with fewer years of education, with
fewer skills with modern digital technologies, and in worse health, especially within nations that
are less digitally developed and harder hit by the epidemic in question
