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
FEDERATED REINFORCEMENT LEARNING FOR CONTENT DISSEMINATION IN UAV NETWORKS
Full text linkThesis (Ph.D.)--Michigan State University. Electrical and Computer Engineering - Doctor of Philosophy, 2025In disaster scenarios with compromised communication infrastructure, Unmanned Aerial Vehicles (UAVs) can provide ad hoc connectivity for resilient information dissemination. This thesis develops a hierarchical UAV-assisted framework of federated multi-armed bandit learning for post-disaster content dissemination. The developed framework incorporates a two-tier UAV hierarchy consisting of Anchor UAVs (A-UAVs) with high-cost backhaul connectivity, and more mobile Micro-Ferrying UAVs (MF-UAVs) without backhaul links. Such a hierarchy allows for strategic offloading of storage-intensive tasks to A-UAVs, while leveraging the mobility of MF-UAVs to dynamically ferry content across disconnected user clusters. By integrating trajectory-aware selective caching strategies into UAV operations, the framework aligns aerial mobility patterns with evolving spatio-temporal content demands. Algorithmic innovation of the framework stems from a federated bandit and stateless reinforcement learning paradigm, which enables UAVs to collaboratively learn content popularity profiles, and adapt caching policies based on localized user request patterns. Unlike centralized methods, the federated approach preserves data locality and minimizes inter-UAV communication overhead, which is critical in bandwidth- and energy-constrained post-disaster environments. The multi-armed bandit learning mechanism utilizes a multi-dimensional reward feedback architecture that captures content relevance, inter-UAV delivery latency, and caching diversity across disjointed and isolated user communities. The thesis also explores the interplay between UAV energy budgets, caching capacities, and mission-critical delivery constraints such as quality-of-service expectations in terms of tolerable access delay. To summarize, the research in this thesis bridges multi-agent learning with mission-oriented aerial networking towards developing solutions for smart content dissemination in networks with sparse connectivity.Description based on online resource.

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
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
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
Quantum Communication: From Fundamentals to Recent Trends, Challenges and Open Problems
Full text linkWith the recent advancements and developments in quantum technologies, the
emerging field of quantum communication and networking has gained the attention
of the researchers. Owing to the unique properties of quantum mechanics, viz.,
quantum superposition and entanglement, this new area of quantum communication
has shown potential to replace modernday communication technologies. The
enhanced security and high information sharing ability using principles of
quantum mechanics has encouraged networking engineers and physicists to develop
this technology for next generation wireless systems. However, a conceptual
bridge between the fundamentals of quantum mechanics, photonics and the
deployability of a quantum communication infrastructure is not well founded in
the current literature. This paper aims to fill this gap by merging the
theoretical concepts from quantum physics to the engineering and computing
perspectives of quantum technology. This paper builds the fundamental concepts
required for understanding quantum communication, reviews the key concepts and
demonstrates how these concepts can be leveraged for accomplishing successful
communication. The paper delves into implementation advancements for executing
quantum communication protocols, explaining how hardware implementation enables
the achievement of all basic quantum computing operations. Finally, the paper
provides a comprehensive and critical review of the state-of-the-art
advancements in the field of quantum communication and quantum internet; and
points out the recent trends, challenges and open problems for the real-world
realization of next generation networking systems
