    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

    Full text link
    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

    Full text link
    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

    How do different explanation presentation strategies of feature and data attribution techniques affect non-expert understanding?: Explaining Deep Learning models for Fact-Checking

    No full text
    The goal of this paper is to examine how different presentation strategies of Explanainable Artificial Intelligence (XAI) explanation methods for textual data affect non-expert understanding in the context of fact-checking. The importance of understand- ing the decision of an Artificial Intelligence (AI) in human-AI interaction and the need for effective explanation methods to improve trust in AI models are highlighted. The study focuses on three expla- nation methods: interpretable-by-design model Ex- Pred, feature attribution technique LIME, and in- stance attribution method k-NN. Two presentation strategies were compared for each method, and par- ticipants were presented with a set of claims and asked to indicate their understanding and level of agreement with the AI’s classification. The main hypothesis is that participants will appreciate all available context and details, as long as it is pre- sented in a structured way, and will find visual rep- resentations of data easier to understand than tex- tual ones. Results from the study indicate that par- ticipants prefer explanations that are simple and structured, and that visual presentations are not as effective, especially when it is the first time a user interacts with this type of data. Additionally, it was found that better formatting leads to a better- calibrated understanding of the explanation. The results of this study will provide valuable insight into the best way to present XAI explanations to non-experts to enhance their understanding and re- duce the deployment risk associated with Natural Language Processing (NLP) models for automated fact-checking. The study’s code, data, and Figma templates are publicly available for reproducibility.https://github.com/shivanisgithub/FactCheckingPresentationsCSE3000 Research ProjectComputer Science and Engineerin

    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

    Přestože kvantové počítače, které mohou překonat konvenční počítače, jsou stále ve vývoji, je pro přípravu na budoucnost kvantové výpočetní techniky zásadní, abychom pokročili v porozumění a vývoji kvantových algoritmů. Tento bakalářský projekt zkoumá rozvíjející se oblast kvantového programování a simulace na aktuálně dostupných kvantových počítačích. Studujeme základy kvantového počítání a shrnujeme běžně používané principy používané v této oblasti. Teoreticky popisujeme kvantové procházky s klíčovým důrazem na varianty s diskrétním časem, které tvoří stěžejní část této práce. Dále představujeme optimalizovanou metodu pro efektivní implementaci kvantových procházek v diskrétním čase vhodnou pro současnou architekturu kvantových počítačů. Ukazujeme, že tato metoda je ve srovnání s běžnými metodami úspěšnější při zkoumání aspektů souvisejících s kvantovými procházkami, jako je dynamika šíření a dokonalý přenos stavu.Although quantum computers that can outperform conventional computers are still in development, it is crucial to advance our understanding and development of quantum algorithms to prepare for the future of quantum computing. This bachelor project explores the growing field of quantum programming and simulation on currently available quantum computers. We study the basics of quantum computing and summarize the commonly used principles used in the field. We theoretically describe quantum walks with a special emphasis on discrete-time variants, which constitute the core part of this thesis. Furthermore, we introduce an optimized method for the efficient implementation of discrete-time quantum walks suitable for the current quantum computer architecture. We show that this method is more successful in examining quantum walk related aspects like spreading dynamics and perfect state transfer compared to conventional methods
