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
Norsk Informatikkonferanse (NIK) 2022 Preface
No full textNIK (Norsk Informatikkonferanse) is a national conference that aims to spread the knowledge of research and advanced development work in the field of infor- matics. The conference encourages the submission of papers from various genres and topics within theoretical and applied informatics. NIK welcomes diversity and cross-disciplinary approaches in methodological techniques and application areas
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
Diagram predicate framework: A formal approach to MDE
Full text linkModel-driven engineering (MDE) is a software engineering discipline which promotes models as first-class entities. It represents a shift of paradigm in software development, from being code-centric to become model-centric. MDE is an attempt to organise modelling, metamodelling and model transformation in a well-structured engineering methodology. This thesis is all about formalisation of MDE-concepts in a diagrammatic specification formalism which we call Diagram Predicate Framework (DPF). DPF provides a formal diagrammatic approach to (meta)modelling and model transformation based on category theory. It is a generic graph-based specification framework that tends to adapt first-order logic and categorical logic to software engineering needs. This thesis is based on a sequence of publications and it is the intended purpose of this thesis to consolidate the present state of development regarding DPF. Some of the foundation for DPF was already under construction before this work was initiated. The main contributions of this thesis are: • An introduction to formal diagrammatic modelling and diagrammatic constraints • A comparison of some of the state-of-the-art modelling languages, techniques and frameworks to DPF • A neat, diagrammatic formalisation of the metamodelling hierarchy as proposed by the Object Management Group • A formal approach to model transformations and to constraint-awareness in model transformation • A formalisation of the fundamental concepts and processes of version control in the context of MDE This thesis is organised as follows. The first chapter is dedicated to introduce MDE, its technological basis and challenges, and to motivate the formalisation approach presented in this thesis. This introduction is meant as a guide for newcomers to MDE, especially for theoreticians. The main part of the thesis details DPF and its formal background. This part is more theoretically oriented, and is meant to elucidate the formal foundation of the DPF framework for software engineers. More precisely, DPF is presented as a formal approach to (meta)modelling, model transformation and version control. The last chapter is dedicated to a discussion of related work, further work and concluding remarks. The content of this thesis is neither purely theoretical nor purely practical; rather it seeks to bridge the gap between these worlds. It provides a formal approach to diagrammatic modelling, model transformation and version control motivated and illustrated by practical examples. We introduce only the theoretical elements which are necessary to investigate, formalise, and to solve the practical problems. More precisely, we explicitly define the formal concepts and constructions needed in order to understand the thesis, such as graph, graph homomorphism, categories, pullback and pushout
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
