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
Disentangling the stigma of HIV/AIDS from the stigmas of drugs use, commercial sex and commercial blood donation – A factorial survey of medical students in China
Full text linkBackground: HIV/AIDS related stigma interferes with the provision of appropriate care and
support for people living with HIV/AIDS. Currently, programs to address the stigma approach it as
if it occurs in isolation, separate from the co-stigmas related to the various modes of disease
transmission including injection drug use (IDU) and commercial sex (CS). In order to develop
better programs to address HIV/AIDS related stigma, the inter-relationship (or 'layering') between
HIV/AIDS stigma and the co-stigmas needs to be better understood. This paper describes an
experimental study for disentangling the layering of HIV/AIDS related stigmas.
Methods: The study used a factorial survey design. 352 medical students from Guangzhou were
presented with four random vignettes each describing a hypothetical male. The vignettes were
identical except for the presence of a disease diagnosis (AIDS, leukaemia, or no disease) and a cocharacteristic
(IDU, CS, commercial blood donation (CBD), blood transfusion or no cocharacteristic).
After reading each vignette, participants completed a measure of social distance that
assessed the level of stigmatising attitudes.
Results: Bivariate and multivariable analyses revealed statistically significant levels of stigma associated with AIDS, IDU, CS and CBD. The layering of stigma was explored using a recently
developed technique. Strong interactions between the stigmas of AIDS and the co-characteristics
were also found. AIDS was significantly less stigmatising than IDU or CS. Critically, the stigma of
AIDS in combination with either the stigmas of IDU or CS was significantly less than the stigma of
IDU alone or CS alone.
Conclusion: The findings pose several surprising challenges to conventional beliefs about HIV/
AIDS related stigma and stigma interventions that have focused exclusively on the disease stigma.
Contrary to the belief that having a co-stigma would add to the intensity of stigma attached to
people with HIV/AIDS, the findings indicate the presence of an illness might have a moderating
effect on the stigma of certain co-characteristics like IDU. The strong interdependence between
the stigmas of HIV/AIDS and the co-stigmas of IDU and CS suggest that reducing the co-stigmas
should be an integral part of HIV/AIDS stigma intervention within this context
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
