The Design and Implementation of Autonomous Identity for Social Network
No full text近年來社群網站蓬勃發展，Google 和 Facebook 等公司透過搜集分析與操作網際網路上的使用者資料，提供了許多智慧化的服務與資訊。不過，這些本來是私人的資料逐漸被這些公司所把持，其中包括許多個人的隱私。於是，不僅難以確保隱私，也難以在不同公司間的各種網路服務分享與修改個人資料。另一方面，社群網站上存在許多假的甚至惡意的資訊，不僅對使用者造成困擾，也浪費了許多社會成本來處理。因此，本論文提出了自主式的社群網路身分 (Aid)，讓使用者能夠完全掌握自己的資料和隱私。我們將 Aid 從網路服務中獨立出來，讓大部份的資訊儲存在本地，並透過數位簽章的機制進行身分驗證。此外，使用者能夠真正自主的前提是使用者要能先為自己的社會活動負責。因此，我們也提出了一個自主的機制來評估如信用度或真實度等 Aid 的度量，讓使用者可以利用這些度量彼此量化評估。目前我們已經實作出 Aid 的雛型以及給服務使用的應用介面，提供多個學校的實驗室開發相關的自主網路服務。透過『自主量化』的 Aid，相信網路身分能變得更加自主可靠，進而提升社群網路活動的品質。As the booming of social network recently, companies such as Google and Facebook provide intelligent services and information by collecting, analyzing, and manipulating user data on the Internet. However, these originally private data which contain lots of privacy gradually become dominated by these companies. Thus, not only might the privacy not be ensured but it is also difficult to share and update personal data among services of different companies. On the other hand, much information is fake or even malicious on social network. It not only confuses users but also wastes lots of social cost to handle. Hence, this thesis proposes an autonomous identity (Aid) for social network to provide users with total control of own data and privacy. Aid is designed independent from network services, most of Aid information is stored locally, and it is authenticated by digital signature. Moreover, users need to be responsible for their social activities before they can be really autonomous. Therefore, we also propose an autonomous mechanism to evaluate metrics of Aid, such as credit or reality, so that users can evaluate one another by these metrics quantitatively. We have implemented the prototype of Aid and application programming interfaces for services, offered some laboratories of some universities to develop autonomous network services. By Aid of "autonomous quantification", we believe network identities become more autonomous and reliable to increase the quality of activities in social network.Contents

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
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

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.
