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

No full textPh.D.The global mobile data traffic has been growing tremendously in the past few years. In order to alleviate the tension between the mobile data demand and the network capacity, the operator can either utilize the spectrum more efficiently, or flatten the demand curve through pricing. Motivated by some recent practices, this thesis focuses on two specific problems. First, we study the cognitive mobile virtual network operator’s spectrum investment problem. Second, we study the mobile network operator’s optimization problems and users’ behaviors in a mobile data trading market. To understand the decisionmakers’ realistic behaviors, our solutions to these two problems focus on not only classical economic perspectives, where decision makers are assumed to be fully-rational, but also behavioral economic perspectives, which captures the realistic human decision process on uncertainty.In the first part of the thesis, we study a cognitive mobile virtual network operator’s spectrum investment problem under spectrum supply uncertainty using prospect theory. We formulate a hybrid spectrum investment problem including spectrum sensing and leasing as a two-stage optimization problem, and compute the optimal sensing and leasing decisions. Our results show that compared with a fully-rational operator, both the risk-averse and risk-seeking operators achieve a smaller expected profit. On the other hand, a risk-averse operator can guarantee a larger minimum possible profit, while a risk-seeking operator can achieve a larger maximum possible profit.In the second part of the thesis, we first analyze the optimal trading strategy for a single user in the mobile data trading market under prospect theory, to understand the users’ realistic trading behaviors with risk preferences. Building upon our analysis, we design an algorithm to help estimate the user’s risk preference and provide trading recommendations dynamically, considering the latest market and usage information. We also study the operator’s optimal operation fee, and the scenarios under which it is beneficial for an operator to propose a mobile data trading market. Our results suggest an operator with a low initial market share to propose a data trading market.全球移動數據流量在過去幾年中大幅增長。為了緩解移動數據需求與網絡容量之間的緊張關係，運營商可以通過更有效地利用頻譜的方式，或者可以通過由定價來平坦化需求曲線的方式。本論文著重於研究兩類具體問題。一，認知移動網絡虛擬運營商的頻譜投資問題。二，移動網絡運營商在移動數據交易市場中的優化問題和用戶在移動數據交易市場中的行為。為了瞭解決策者的現實行為，我們的方法不僅側重於經典經濟學理論觀點，即決策者被認為是完全理性的，而且還包括行為經濟觀點，從而捕捉現實決策過程中面對不確定性時決策者的行為特徵。在論文的第一部分，我們使用前景理論研究了認知移動網絡虛擬運營商面對頻譜供應不確定性時的頻譜投資問題。我們建模了一個包括頻譜感知和頻譜租賃的兩階段混合頻譜投資問題，並計算出最優的頻譜感知和頻譜租賃的決策。我們的研究結果表明，與完全理性的運營商相比，風險厭惡和風險尋求型的運營商都會得到較小的預期利潤。另一方面，風險厭惡型的運營商可以保證更大的最小可能利潤，而風險尋求型的運營商可以獲得更大的最大可能利潤。在論文的第二部分，我們首先分析移動數據交易市場中單一用戶在前景理論下的最優交易策略，從而瞭解現實交易中，風險偏好對用戶行為的影響。基於我們的分析，我們設計了一種交易算法來幫助估計用戶的風險偏好，並基於最新的市場信息和用戶數據用量信息，提供動態交易建議。我們同時還研究運營商的最優運營費用的決策，以及使得運營商可以依靠推出移動數據交易市場而獲益的場景。研究結果表明，初始市場份額較低的運營商可以靠推出數據交易市場而獲益。Yu, Junlin.Thesis Ph.D. Chinese University of Hong Kong 2017.Includes bibliographical references (leaves 154-162).Abstracts also in Chinese.Title from PDF title page (viewed on 22, August, 2019).Yu, Junlin
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.
