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
죄수의 딜레마 게임 측면에서의 개인의 경제행동과 사회 상호작용 분석: 시뮬레이션 방법을 이용하여
Get PDF학위논문 (석사)-- 서울대학교 대학원 : 기술경영·경제·정책전공, 2017. 2. Jorn Altmann.개인의 의사 결정 과정에 대한 전통적인 미시 경제 개념에서 시작하여 선택은 합리적인 행동과 효용 극대화의 개념에 기초하여 이루어진다. 그러나 행동 경제학 분야의 여러 연구에서 의사 결정 과정을 더 잘 이해하고 대표하기 위해이 전통적인 모델과 보완 이론에 의문을 제기했다.
이 연구는 의사 결정 과정에 존재하는 제한된 합리성과 관련된 행동 경제학의 진술을 분석하고 개인적 관점에서 집단적 차원으로 바라보고자, 다중 에이전트 기반 모델링과 같은 전산 경제학 기법, 사회 및 경제 네트워크, 죄수의 딜레마 게임의 수정 버전을 사용한 모델을 제시한다. 소셜 네트워크 시뮬레이션에서 에이전트 기반 모델은 게임 성능 및 결과에 관한 특수성을 연구 할 목적으로 개인의 경제적 행동과 사회적 상호 작용을 모방 할 수있게 한다.
본 연구의 결과는 인공 환경에서 개인의 비합리적 행동을 재창조하고 사회 시나리오에서의 합리적 행동과 비교할 수 있는 가증성을 제시한다. 연구 결과에 따르면 게임의 결과는 임계점, 전환 시간 및 지배 전략의 전환과 관련하여 합리적이고 비합리적인 행동의 차이가 있음을 시사한다. 이 연구의 향후 응용 방안은 정책 설계를 개선하고 사회에 미치는 영향 분석이다.Starting from the traditional microeconomic concept of the individuals decision process, choices are made based on the concepts of rational behavior and utility maximizationhowever, several studies from the field of behavioral economics have questioned this traditional model and proposed complementary theories in order to understand and represent the decision-making process better.
To analyze the statements of behavioral economics related to bounded rationality present in the decision-making process and looking from individual to collective levels, this research offers a model using the techniques of computational economics, such as multi-agent based modeling, and the concepts of social and economic networks. The proposed model recreates a scenario of the game on networks using a modified version of the Prisoners Dilemma game. The agent-based model in a social network simulation allows us to emulate individuals economic behavior and social interactions with the purpose of studying particularities concerning game performance and outcomes.
The results of the present research demonstrate that in an artificial environment, it is possible to recreate the irrational behavior of individuals and compare it with rational behavior in a social scenario. The findings show that the outcome of the game has differences between rational and irrational behavior in terms of threshold point, conversion time, and transition of the dominant strategy. The application of this research can improve the design of policies and analyze their impact on the society.Chapter 1. Introduction 1

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
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.
