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

Full text linkVariations 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
Analysis of Categorical Data from Historical Perspectives Essays in Honour of Shizuhiko Nishisato
No full textThis book marks a celebration of the career and influence of our dear colleague and
friend, Prof Shizuhiko Nishisato, or “Nishi” as we call him, in honour of his 88th
birthday. Such a milestone deserves a moment to sit back and reflect upon a life
filled with happiness, hope, at times sadness, but with love and passion for all that
drives us forward. So it is with this Festschrift that we all celebrate Nishi’s career
and the influence (both personal and professional) he has had on us all. It is also our
opportunity to thank him for all he has done for us as editors, and for everyone who
was able to contribute to his Festschrift and those who were unable to do so.
Our connection to Nishi dates back about 20 years and so it is relatively young,
certainly in comparison with many of those who have contributed to this book. A key
moment was the first face-to-face meeting of the Nishi/Clavel and Beh/Lombardo
teams at the IFCS (International Federation of Classification Societies) Conference
in Tokyo in 2017. From this meeting came the 2021 Springer book that we had
the pleasure to co-author with Nishi titled Modern Quantification Theory: Joint
Graphical Display, Biplots and Alternatives. So, it came as a pleasant surprise in late
February 2022 that we were invited to edit his Festschrift. Of course, we said “yes”.
We would like to acknowledge the early involvement of Prof. Yasumasa Baba who
is a long-term dear friend of Nishi and who was originally committed to this project
but, unfortunately, was unable to continue in the role.
Nishi’s career spans a great many achievements that are laid out in many of the
papers of this book, and so we leave it to you to peruse the pages and appreciate
the depth of work he has committed a lifetime of passion to. It is safe to say his
impact on quantification theory, and the vast array of research avenues this covers, is
profound. Therefore, this Festschrift is a celebration of many of these avenues and
is divided into four broad topics. The first, “Data Theory” provides a mix of written
and pictorial accounts of Nishi’s life and his work. It also gives some perspective of
Nishi’s influence in the context of the career of Prof. Chikio Hayashi, an early and
highly influential pioneer of quantification theory. The next major part of this book
is titled “On Associations and Scaling Issues” and includes papers that celebrate
Nishi’s impact on the numerical issues concerned with dual scaling and its related
methods, as well as providing new insights into this area of research. A more visual

x Preface
appreciation of the scaling issues is explored in “On Correspondence Analysis and
Related Methods”. Here, the papers discuss a range of issues including the naming
conventions used in the past, exploring the anatomy of correspondence analysis and
detailing extensions of correspondence analysis for analysing various data structures.
The final part of Nishi’s Festschrift is titled “General Topics” and includes papers
that are not necessarily related to issues concerned with quantification theory but
are here because of the close professional and personal connections that Nishi has
shared with the authors over the years.
This celebration of Nishi’s career is a collection of 29 papers where all the
corresponding authors and some of their co-writers were all personally invited to
contribute. We must also acknowledge those who were invited to contribute to this
collection and prepared an early version of their work for inclusion but, ultimately,
were unable to do so. Every one of those who have been invited to contribute to
this collection all share a personal and professional bond with Nishi. These papers
are written by 45 authors that come from all corners of the globe; in alphabetical
order, Australia, Barbados, Canada, England, France, Germany, India, Italy, Japan,
the Netherlands, Scotland, Spain, Switzerland, and the USA.
The preparation of Nishi’s Festschrift would not have been possible without
the help and support of Springer. So, we thank them, and especially Sridevi
Purushothaman, for the many email queries that were patiently responded to. We
also extend our heartfelt appreciation to Pieter Kroonenberg, our close personal
friend and of Nishi’s, for writing the Foreword to this book. Our biggest thanks goes
to each of the authors who have contributed to this collection of celebratory papers.
It has been an immense pleasure communicating with each and every one of you and
the email conversations that have followed. We thank you for your commitment to
this book and for helping to celebrate Nishi as the kind and endearing person that he
is and for the role he has played over the decades as a researcher who has committed
himself to the development of quantification theory and its related methods.
No one succeeds in life without the love of those around them. While we have
all provided various degrees of professional and/or personal help and support over
many years (and decades), his successes rest primarily with his wife Lorraine. So, on
a personal note, we thank Lorraine for her support and love as Nishi has carved a wide
long path through his academic career, a path that many of us have travelled alongside
Nishi or behind him. Whether you subscribe to the phrase of Scott Fitzgerald behind
every great man there is a great woman or Tariq Ramadan’s behind every great man
is not a woman, she is beside him, she is with him, not behind him, or even Jim
Carrey’s behind every great man is a woman rolling her eye, Lorraine’s influence has
been a blessing to us all. So, thank you Lorraine. Finally, we thank Nishi for inviting
us to edit his Festschrift and wish him continued health, happiness and love as he and
those around him continue to mould and direct the next generation of researchers.

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
