Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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

Living Tongues Institute Collection
This is a beginner-level children's book in the Birhoɽ language of India, a minority ‘tribal’ language belonging to the Munda language family. ""Abun Ari Re (Our Surroundings)"" represents the first-ever publication in this endangered language. Several hundred copies were printed and freely distributed by Living Tongues Institute researchers to Birhor communities in 2022. The Birhoɽ were formerly a nomadic group specialized as natural-vine-fibre rope makers. This book targets the earliest age group of schoolchildren. It is the age where the children learn words from their mother tongue by looking at objects from their surroundings. This book has been created keeping in mind various topics such as relations, body parts, animals, vegetables and so on. Engaging images have been created to illustrate various topics, keeping in mind the natural ability of children to learn words of their mother tongue that they come across every day. The names of each of the pictures are written in three languages (Birhoɽ, Hindi and English) by using Devanagari and Roman script. The book is intended as a way to both have Birhor-speaking children transition easily to Hindi-medium and English second language education as well as to help reinforce the retention and use of the Birhor language by younger community members who have been increasingly shifting to dominant local languages. The forms in the Birhoɽ language have been written in red to make it easier to emphasize the Birhoɽ language and to facilitate children's reading of the words, as well as being recited aloud by caregivers or parents of the schoolchildren. The book was authored by Living Tongues linguist Dr. Bikram Jora, while India-based artists Khandu Degio, Sashi Kant Lakra and Dipika Hemrom contributed the illustrations. Birhor speakers such as Bishwanath Birhoɽ, Madhuri Birhoɽ, Kameshwar Birhoɽ, Kaushila Birhoɽ, Bitni Birhoɽ, Malti Birhoɽ, Seema Birhoɽ, and Anil Birhoɽ served as language consultants on this project. The content was edited by Dr. Bikram Jora, Dr. Luke Horo, Dr. Gregory D. S. Anderson, Anna Luisa Daigneault, M.Sc, and Anukaran Marki. Sashi Kant Lakra and Dr. Bikram Jora worked on the graphic design. This project was supported by the Zegar Family Foundation

koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
