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
Use of keystroke logging to collect cognitive validity evidence for integrated writing tests
Full text linkIntegrated writing tasks are commonly used for teaching, learning and assessment purposes in most higher education contexts. These tasks are cognitively demanding as they require students to transform knowledge by engaging in processes of discourse synthesis, i.e. selecting, organising, and connecting information from multiple source texts into a new or synthesis text. The purpose of the present exploratory study was to investigate L2 writers’ discourse synthesis processes underlying the performance of an integrated reading-writing task. The participants were three university students who completed an integrated reading-writing task as part of a postadmission academic literacy test at a British university. Data were collected using a variety of qualitative research techniques: analysis of keystroke logs, retrospective interviews, and text quality analysis. Data analysis revealed distinct engagement in discourse synthesis processes among L2 writers. The study proposes a qualitative approach to analysing keystroke logging data to collect cognitive validity evidence (i.e. test takers’ engagement in discourse synthesis) underlying integrated writing test performance. The other major implications of the findings are the need for explicit teaching and assessment of these discourse synthesis processes, i.e. selecting, connecting and organising relevant ideas from multiple reading stimuli to produce a text, and the need to construct specific rating descriptors which reflect skills of discourse synthesis for integrated writing tasks

Paper-based vs computer-based writing assessment: divergent, equivalent or complementary?
Full text linkWriting on a computer is now commonplace in most post-secondary educational contexts and workplaces, making research into computer-based writing assessment essential. This special issue of Assessing Writing includes a range of articles focusing on computer-based writing assessments. Some of these have been designed to parallel an existing paper-based assessment, others have been constructed as computer-based from the beginning. The selection of papers addresses various dimensions of the validity of computer-based writing assessment use in different contexts and across levels of L2 learner proficiency. First, three articles deal with the impact of these two delivery modes, paper-baser-based or computer-based, on test takers’ processing and performance in large-scale high-stakes writing tests; next, two articles explore the use of online writing assessment in higher education; the final two articles evaluate the use of technologies to provide feedback to support learning
