Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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

Homotopy Type Theory for Sewn Quilts
No full textThe higher equality structures of homotopy type theory (HoTT) lend the field to topological interpretations in visualizations. In this work, we take these interpretations to their logical extreme in the development of PieceWork, a programming language to represent sewn quilts. We leverage several layers of equality to represent quilts as geometric shapes which can be manipulated in several ways, such as cutting into smaller shapes or sewn together to form an intricate design
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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

Regular Session Types
No full textWe introduce Regular Session Types (RST), a (binary, synchronous, classical) session-typed calculus for which we prove a direct correspondence with regular languages, in addition to progress and preservation. Compared to recent studies of regularity in session types, RST’s contribution is that it makes the treatment of regularity particularly straightforward. To achieve this, the main technical novelties in RST are the internalization of iteration as a first-class type connective and the stratification of session types into read and write session types. The read and write types correspond directly to negative and positive types from polarized session types with one key modification: positive and negative operators are not freely intermixed
Gender Differences in Story, Game and Visual Adventures in Hedy
No full textEven though the field of Computer Science (CS) affects different aspects of society, several groups of society are underrepresented, including women and nonbinary people. Children might have different learning opportunities in CS due to their project preferences. Girls are likelier to work on stories and simple programs in Scratch, whereas boys tend to create games and more complex programs. We explore whether preferences and program implementation differ between genders within a story, game and visual adventure in Hedy, a gradual textual programming language. We analysed 14,233 programs within five Hedy levels created by 2,819 users who turned 10 to 14 in 2023. We found that boys, girls and nonbinary children worked most on the game adventure. Within the individual adventures, gender differences occur in all three adventures in the most elaborate Hedy level analysed. However, for some levels, no gender differences were found. Thus, programming assignments can be created in which children of different genders work on similar programs in terms of size and number of (unique) commands used.</p
Roles of Variables in the Hedy Programming Language
No full textThe concept of variables can be hard to grasp for novices. The Roles of Variables framework has been found to enhance learning elementary programming. The 11 roles can describe all variables in novice programs in 99% of the cases. Prior work has shown that the roles give novices better program comprehension capabilities and better programming skills. In this paper we apply the Roles of Variables to Hedy. Hedy is a gradual and multilingual programming language for education. It consists of 18 levels, each supporting new concepts or requiring code that satisfies new syntax rules, to gradually learn programming in Python, and it is available in 50 different (natural) languages. In this paper we explore how to integrate the roles into Hedy. We reflect on the roles by applying them in a new setting and it could later on become useful for the users of Hedy.</p
