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
A Firm-Level Analysis
No full textUsing a policy change in the
Netherlands in 2012 that made it easier and less costly for
firms to employ high-skilled short-stay non-European Union
workers and a matched employer-employee data, this paper
shows that firms in high-skill industries respond by both
employing a higher share of non-European Union immigrants
and increasing the total amount of offshoring to
non-European Union countries. With reduced costs of hiring
short-stay non-European Union workers, small firms hire and
fire more non-European Union workers in a given year. Many
of these workers return to their home countries,
establishing direct connections that boost offshoring to
firms in the Netherlands. By contrast, large firms absorb
some of the workers leaving the small firms. These workers
also establish connections between their host and origin
countries, boosting offshoring
The Effects of Communal Violence on Women’s Marital Outcomes
No full textThis study examines the effects of communal violence, that
is violence inflicted upon a particular group along ethnic or
religious lines, on women’s marital outcomes. Communal
violence, with its accompanying psychological and physical
trauma, can have important socioeconomic consequences.
The effects could be very different for women who are often
disproportionately subject to sexual violence during such
events. Using individual-level survey data from India and
a difference-in-differences approach, the study shows that
women’s age of marriage decreased, and the probability of
getting married before the age of 18 increased after the
Hindu-Muslim riots in Gujarat in 2002. The Gujarat riots
stand out as one of the most significant and abrupt occurrences of communal violence in post-independence India,
marked by widespread violence against women, thus providing a setting to study the impacts of such violence on
women. Event study and synthetic control methods suggest
that these effects are prominent two years after the riots and
have increased over time. Women married after the riots
also had fewer years of education and poorer social and
economic status, such as a lower probability of employment
and lower autonomy in household decision-making
Trade, Internal Migration, and Human Capital: Who Gains from India's IT Boom?
No full textHow do trade shocks affect welfare and inequality when
human capital is endogenous? Using an external IT demand
shock and detailed internal migration data from India, this
paper first document that both IT employment and engineering
enrollment responded to the rise in IT exports.
IT employment responded more in regions with a higher
college-age population. The paper then develop a quantitative
spatial equilibrium model featuring two new channels:
higher education choice and differential costs of migrating
for college and work. Using the framework, I quantify the
aggregate and distributional effects of the IT boom and
perform counterfactuals. Without endogenous education,
the estimated aggregate welfare gain from the export shock
would have been about a third, and regional inequality
twice as large. Reducing barriers to mobility for education,
such as introducing a national scholarship for students at
higher education institutes, would substantially reduce
inequality in the gains from the IT boom across districts
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
