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

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Early Sunnī historiography: a study of the Tārīkh of Khalīfa b. Khayyāṭ
No full textThis thesis is a study of the oldest Islamic chronological history still extant: the
Tārīkh (‘Chronicle’) of the Basran ḥadīth scholar and historian Khalīfa b. Khayyāṭ
al-ʿUṣfurī (d. 240/854), which covers the political and administrative history of the
Muslim polity between year 1/622 and 232/847. Despite its early date, Khalīfa’s
Tārīkh has received little attention in modern scholarship and its value for
understanding the development of early Islamic historiography has generally been
disregarded. The purpose of this study is, therefore, to reassess the Tārīkh by
analysing both the text and its context of compilation. After outlining Khalīfa’s
biography (Ch. 1) and his social and intellectual context (Ch. 2), the thesis examines
different aspects of Khalīfa’s Tārīkh in comparison to the wider Islamic historical
tradition: his sources (Ch. 3), methods (Ch. 4), arrangement of material (Ch. 5) and
narrative treatment of key themes in the early tradition (Chs. 6–7). The thesis thereby
provides an in-depth study of one of the earliest Muslim historians and his methods
of compilation, which is important for both the study of Islamic historiography and
the usage of such sources in historical scholarship on early Islam.
It is argued that Khalīfa’s role as a ḥadīth scholar and his early Sunnī outlook
is reflected throughout the content of the Tārīkh. This is particularly evident in
Khalīfa’s selection of sources, which consist of mainly Basran transmitters including
numerous major ḥadīth scholars, and in his narration of controversial events such as
the early civil wars, which displays an early Sunnī perspective. It is also suggested
that Khalīfa’s particular selection and arrangement of material was largely
determined by his aim to compile a critical and concise chronology of the political
and administrative history of the Muslim community. Moreover, the thesis shows
that, while the Tārīkh differs from many other early histories, it bears some
resemblance to other chronographies compiled by early ḥadīth scholars—such as the
works of al-Fasawī (d. 277/890), Ibn Abī Khaythama (d. 279/892) and Abū Zurʿa al-
Dimashqī (d. 282/895) as well as the sections on post-Prophetic history in some
ḥadīth collections such as Ibn Abī Shayba’s (d. 235/849) Muṣannaf. By comparing
Khalīfa’s Tārīkh with these works, the thesis draws attention to this type of historical
writing among some early ḥadīth scholars, which has so far been neglected in
modern studies on early Islamic historiography
The Tafsīr of Sufyān al-Thawrī (d. 161/778): a study of its provenance, sources, methods, and topics
Full text linkThe aim of this thesis is to enhance our understanding of the contributions of Sufyān al-Thawrī (d. 161/778) to the field of early Qurʾānic exegesis through a detailed study of exegetical traditions attributed to him recorded in a unique and fragmentary manuscript in Rāmpūr. While scholars have speculated about its character, so far it has largely escaped a detailed historical-critical assessment preventing a deeper understanding of its sources, methods, and topics of exegesis.
Using a detailed and comparative study of the biographical and exegetical material with the Rāmpūr text, this thesis established the chain of transmitters through which this text might have been transmitted. This uncovered an obscure recension of the Tafsīr of al-Thawrī highlighting Iṣfahān as a region whose importance for Qurʾānic exegesis has been unrecognised. Through a study of the structural and stylistic features of the Rāmpūr manuscript and comparison with later sources, this thesis demonstrated that the text displays the character of personal lecture notes based on that recension. It also showed that from these notes, an imaginative reconstruction of the original theme-based lectures might be possible through a new reading of the text. These findings establish that the text belongs to an early period and is therefore a valuable source for studying early Qurʾānic exegesis.
A comparative analysis with later exegetical material modified previous assessments showing that the reliance on his personal opinions is much smaller than understood. His exegetical interventions were more visible in his bringing together various traditions on the same Qurʾānic text, referring to out-of-sequence verses as part of a larger theme, and clarifying the statements of earlier authorities. Using a different categorisation based on the subject matter, this thesis showed that al-Thawrī was mostly interested in theological themes and topics as compared to historical or legal. It also highlighted how a particular method of explaining the text formed his opinion on a legal or theological topic whereas some of his personal opinions could not be ascertained clearly from the text.
Thus, the Tafsīr of al-Thawrī gives a detailed insight into the way it was transmitted, about his role as an exegete in his own right, his exegetical approaches and methods, and his overall contribution to the early Qurʾānic exegesis
