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
Метод побудови мережі підтримки високощільного Інтернету речей з інтеграцією технологій SDN та MEC
No full textThe deployment of high- and ultra-high-density Internet of Things (IoT) systems poses a number of technical and organizational challenges. One promising approach to addressing these challenges is the integration of advanced network and data processing technologies, in particular Software-Defined Networking (SDN) and Multi-Access Edge Computing (MEC). This paper aims to explore the process of integrating SDN and MEC technologies into support infrastructures for high- and ultra-high-density IoT. Results. The study proposes an architecture for an integrated IoT–SDN–MEC system comprising both terrestrial and aerial segments. A mathematical model has been developed for this architecture, enabling the evaluation of energy consumption in fog-layer devices as well as the estimation of task execution delays. In addition, a traffic offloading scheme for the integrated IoT–MEC–SDN system is presented. The research formulates the problem of optimizing energy consumption and task processing delays in the aerial segment. To address this problem, the Grey Wolf Optimizer (GWO) algorithm is employed, providing efficient near-optimal solutions. Conclusion. Simulation results demonstrate that incorporating fog-layer resources within the aerial segment of the integrated IoT–MEC–SDN system significantly reduces both average energy consumption and average task processing delays in high- and ultra-high-density IoT environments. Future research will focus on determining the optimal structural configuration of the aerial segment.
При впровадженні ІоТ високої та надвисокої щільності виникає низка технічних та організаційних проблем. Одним з напрямів подолання цих проблем є інтеграція технологій опрацювання мереж та даних, зокрема SDN ТА MEC. Отже, метою даної статті є дослідження процесу інтеграції технологій SDN ТА MEC в системи підтримки високощільного та надвисокощільного Інтернету речей. Отримані результати. Запропонована архітектура інтегрованої системи ІоТ-SDN-МЕС, що складається з наземного та повітряного сегментів. Для даної архітектури розроблена математична модель, котра дозволяє визначати енергетичні витрати пристроїв туманного шару та часові затримки виконання завдань. Описана схема вивантаження трафіка в інтегрованій системі ІоТ-МЕС-SDN. Сформульовано завдання оптимізація енергоспоживання та затримок обробки завдань, вивантажених у повітряний сегмент. Для його вирішення застосований алгоритм зграї сірих вовків, який допомагає швидко знайти наближений розв’язок. Висновок. Проведений аналіз результатів моделювання функціонування інтегрованої системи ІоТ-МЕС-SDN показав, що при використанні у туманному шарі повітряного сегменту для високощільного та надвисокощільного Інтернету речей зменшуються середні енерговитрати та середня затримка, що виникає при обробці обчислювальних задач. Подальші дослідження у даному напрямі пов’язані з формуванням оптимальної структури повітряного сегменту
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
