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
Service selection middleware using blockchain for IoT applications
Get PDFIn today’s world, the Internet of Things (IoT) has ushered in an unprecedented revolution in information technology and is used in many industries, including retail, manufacturing and healthcare. Each individual IoT application is different when it comes to functional and nonfunctional requirements, defined by the application owner or industry. Service provider selection in a decentralized environments have become a critical issue for different IoT applications, in particular when services providers having similar functionality but different Quality of Service (QoS). As a result, selecting a high quality service that best suits IoT application requirements from a large list of functionally equivalent services is a challenging task. Furthermore, it is challenging to secure the private and business-critical information of the IoT application, as the sharing of service parameters with third-party solutions or even with the service provider itself can create serious security and privacy concerns, since the service requirements could contain sensitive information regarding the application, that could be misused or sold by the third-party or service provider. Therefore, a decentralized service selection mechanisms are required to select the best service provider for IoT applications, while ensuring end-to-end security and privacy of the associated sensitive data.
In this thesis, we first consider an IoT data storage selection problem, which focuses on a middleware design for blockchain-based intelligent data storage selection for large-scale IoT applications. The proposed framework extends the current IoT cloud architecture and considers peer-to-peer (P2P) and blockchain-based storage solutions along with cloud and multi-cloud technologies. We model IoT data storage selection problem as a decision optimization problem and propose two polynomial-time algorithms as a solution. We also propose a verifiable blockchain-based storage selection protocol, which enables the IoT applications as well as the storage technologies to verify the correctness of the data placement decision made by the middleware design without the need of any trusted third party. Finally, we propose an intelligent maintenance strategy, which takes into account and learns the dynamically evolving features of the IoT applications service requirements to optimizes the computational complexity along with the blockchain storage and transactions overhead in the middleware design.
The second aspect of the work in the thesis is the development of a blockchain-based efficient and secure charging station (CS) selection protocol for electric vehicles (EV) charging networks. We propose a decentralized blockchain-based EV charging architecture and theoretically model a decentralized decision optimization problem, which eliminates the need of any trusted third party and enables the EVs and the CSs to communicate in a decentralized manner, through the smart contracts, running on a blockchain network. It also enables EVs to select a CS and make a remote reservation with a CS without sharing any private information with CSs or any central management entity.
The third part of this thesis extends the second aspect of this thesis, and concerns the security and privacy problems arisen by the linkability of the public blockchain addresses with the EV owner’s physical identity. To solve this problem, we propose a blockchain-based end-to-end privacy-preserving CS reservation protocol, which enables EVs to reserve a charging slot at the selected CS privately, without sharing their private information and by dissociating its real identity from the blockchain address, thereby preserving the EV’s privacy. As the information provided by CS cannot be trusted, we propose an SMC-based CS information verification protocol that allows EVs to collaboratively verify the availability of charging slots from the CS by securely sharing reservations in an untrusted environment. Finally, we propose a smart contract design based on time-lock deposit protocols, which aggregates the balance in such a way that no CS is able to link charging service payments with EV users’ blockchain addresses, while still ensuring that CSs receive full payment for the services they provide.
The major contribution of the thesis is providing a secure and efficient service selection mechanisms tailored for different IoT applications with different service requirements and security needs. With the proposed approach consumers will be able to securely select a suitable service provider based on their requirements. Experimental results showed that proposed approaches achieved better performance and efficiency compared to state-of-the-art
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
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.
