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
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
DISTRACTION DETECTION AND INTENTION RECOGNITION FOR GESTURE-CONTROLLED UNMANNED AERIAL VEHICLE OPERATION
Get PDFGesture Control as a way to replace more conventional remote-control operations has been pursued for a significant period of time with different levels of success. The use of gestures to control different types of human interfaces is today predominantly seen in the multimedia sector. People perform easy and intuitive gestures to control their televisions, to interact with multimedia, and to play games. Also, much research has been carried out to experiment with human interfaces to numerous augmented and virtual reality devices and tasks. The results of these experiments were so exciting that researchers started to expand the use of gestures to control physical real-life objects using gestures. One such gesture control platform is controlling an Unmanned Aerial Vehicle (UAV) during flight using hand movements and other types of significant gestures. While the use of gestures as an intuitive way to control such a platform is very promising, it also brings with it a number of challenges and risks that need to be addressed. The main challenges here arise from the versatility and universal character of gestures which make them more susceptible to misinterpretations in terms of user intentions in particular in the context of real-world distractions which can lead to the unintentional generation of gestures outside the context of the control task. The scope of hand gestures is so varied that predicting the gesture using a designated framework could, at a point, be risky for the UAV, where a non-gesture movement possibly generated in the context of natural or artificial distraction could be classified as a control signature and cause a dramatic failure of the UAV. For instance, if a human subject entitled to control the UAV using their hand movements is subjected to an unanticipated situation that made him busy to perform any other similar looking gesture, and the framework misinterprets it to be a known gesture, the result of executing the unintended command might end the life of that drone. In the work presented here, we have mainly focused on an instance where the human subject was considered to be subjected to different types of distraction while controlling the UAV using hand gestures. The UAV controls are suspended to avoid any self or collateral damage whenever any distraction from the brain or hand movements is identified. Finally, once distractions abate, the UAV shifts to ready mode in order to receive new commands. The experimentation is performed using wearable Electromyography (EMG) Sensor armbands and non-invasive Electroencephalography (EEG) Sensors worn on the head. The Armband is co-fitted with both EMG and Inertial Measurement Unit (IMU) Sensors responsible for extracting the muscle movement and the motion-sensing data. The EEG Sensor is used to get the brain data to identify the distracted brain sequences during the operation. An intuitive gesture set for drone operation is designed and a neural network pipeline was set up which was used to identify the gesture performed as well as the current state of the brain. The pipeline constituted a Long-Short Term Memory (LSTM) network classifying the gestures and an Anomaly Detector, which identified periods of operation that correspond to distractions where the human was likely no longer focusing on UAV operations. The LSTM was able to classify 99.52% of the gesture set correctly and the anomaly detector had an accuracy of 90.0006%. The precision of the distraction classifier was 91.86% and the recall was 93.89% for a dataset having nearly 30% of distracted data samples. The signals were recorded from a single human subject over 3 minutes intervals and 20 repetitions with a rest period of 5-10 minutes to avoid brain and muscle fatigue
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
