    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

    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

    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

    Enhancing Customer Churn Prediction in Telecom Using Federated Learning

    No full text
    Customer Churn is one of the major problems within the field of telecommunications. It directly affecting profits and the strategy undertaken for user retention. Most of the conventional techniques for predicting customer churn require sharing private information about customers. This introduces a significant risk of data leakage and violation of regulations. The study proposes an alternative approach to better predict churning with data privacy based on Federated Learning. In other words, FL lets you directly train machine learning models on source data in different places, one would keep a regional customer database up to date with sensitive customer data, since only model parameters would change and not the raw data itself. The study tells about how to use a Simple NN in a Federated Learning setup, with datasets spread out over three geographical nodes that focus on different types if customers in Mumbai, Ohio, and Ireland. It has batch normalisation for stability and ReLU activation for non-linearity, making it best for predicting churn in a binary way. The FedAvg algorithm will be used to combine the local model changes into a single global model over and over again during the training process. Key performance measures, like F1-score, accuracy, precision, and recall, are used to show how well the model works and how close it is to being perfect. My findings show that the suggested framework is strong and improves the accuracy of churn prediction by a large amount, with an F1-score of 83.45 and an accuracy of 84.40 % is the highest among seven attempts. It shows that federated learning works for training high-performing models together across decentralised data while still protecting privacy. This study shows that FL can be used on a large scale and in real-life telecom settings. It also leads the way in customer data with privacy protection. For future work, the combination of automation with advanced methods of grouping is also in thought. This will make the model even better at what it does and make it more efficient

    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
