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

No full textVariations 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

Editorial: Understanding Gamma Delta T Cell Multifunctionality - Towards Immunotherapeutic Applications
Full text linkIntroduction:
gd T cells have been characterized by the expression of a gd T cell receptor (TCR).When the gd TCR
and the corresponding ab TCR were first discovered it was assumed that the corresponding cell
types were likely to be functionally very similar. However, some 30 years later, we have realized that
they are not. Unlike ab T cells, gd T cells (i) sense target antigens independent of MHC molecules;
(ii) display NK-cell like innate reactivities, including killing of infected cells as well as microbes;
(iii) are able to take up large particulates, including bacteria, and (iv) can act as professional antigen
presenting cells.
The “stress sensing” abilities of gd T cells have led to a great interest in exploring their potential
use in novel immunotherapies, not least in cancer. In addition, their capacity to produce various
cytokines and to interact with other cells, such as lymphocytes, myeloid cells, and neutrophils,
has raised an interest in their potential therapeutic use as immunomodulators. gd T cells have
therefore recently come to stand out as a distinctly unique cell type. At the same time, we have
come to realize that gd T cells are likely to be an ancient cell type with ancestors as far back as in
our common ancestors to jawless fish and thereby, potentially predating the development of our
adaptive immune system.
It is clear that to make full use of the great potential of gd T cells in immunotherapeutic
interventions, we must significantly improve our understanding of the extensive plasticity and
multifunctionality of gd T cells and of how these cells can be harnessed therapeutically, both safely
and effectively.
This Research Topic, contains 26 articles which includes Review, Original Research, and
Methods articles in the area of gd T cell plasticity and multifunctionality, As shortly overviewed
in this editorial, these articles shall not represent entire field of gd T cell biology but primarily
focuses on how an increased knowledge in this area can be used and developed further toward
improved immunotherapeutic applications in cancer, infectious disease, autoimmunity, and other
immunity-related areas
