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

What is the measure of success in HIV? The fourth 90: quality of life or healthy aging?
No full textIn the short time frame of 30 years, HIV research has been able to modify AIDS from a rapidly progressive disease leading
inevitably to death to a chronic condition. Even more, the health status of people living with HIV (PLWH) has significantly
improved reducing the burden of symptoms and improving quality of life (QoL). After introduction of the UNAIDS agenda
on the “90–90–90 targets”, it remains unclear what should be the next target in HIV care and research. The objective of
this paper is to critically discuss potential new outcomes to be used as a measure of success in PLWH both in clinical and
research settings.
Methods To better portray potential outcomes, we will critically discuss epidemiological and clinical outcomes, patientreported
outcomes (PRO), and public health outcomes reported in literature. These outcomes intersect with one another
which may suggest contemporary use of different outcomes depending on goals we want to achieve. New outcomes should
go beyond undetectability, be patient-centred, and similar to those in geriatric medicine and the general population.
Conclusions HIV care can take advantage of experience from geriatric medicine and teach-back by describing aging trajectories
in PLWH that may be accentuated in comparison to general population. However, we still need to improve tools to
measure quality of life, PROs, and healthy aging. Healthy aging assessment will allow us to recognize unmet needs in PLWH
and represents an integrated model between community, the person, and healthcare providers, wherein all stakeholders are
linked, increasing possibilities for effective intervention
