Wide area 3D seafloor reconstruction and its application to sea fauna density mapping
No full text3D visual mapping of the seafloor has found applications ranging from environment monitoring and survey of marine minerals to underwater archeology and inspection of modern man-made structures. However, the attenuation of light is significantly more pronounced in water than in air or in space, and so in order to obtain underwater images in colour, it is typically necessary to be within 2 to 3m of the seafloor. In addition to the high risk of collision when operating underwater vehicles at such low altitudes, the limited area of the seafloor covered in each image means large area surveys require a huge investment of time. In this research, we aim to increase the efficiency of mapping large areas of the seafloor by developing an underwater imaging system that can take colour images at ranges of up to 12 m, so that each image can cover a larger area, together with the necessary algorithms to automatically process the data it obtains. The system was deployed to map artificial hydrothermal vents in Iheya North Knoll using the ROV Hyper-Dolphin in October 2012. In this paper, we describe the methods used to process the data it obtains and present wide area 3D reconstructions of habitats surrounding artificial hydrothermal vents. Habitats of Shinkaia crosnieri squat lobsters, which are abundant in the hydrothermally active areas, are identified in the maps and their population density calculated
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
An Index to the Articles in the Chinese Literary Magazine Chao Foon, 1955–1999
No full text本目錄列出了華文文學雜誌《蕉風》自創刊（1955年11月）至1999年2月暫時停刊的488期目錄。下列人士和组織協助了本目錄的编制工作。筆者要感謝他們所有人。感謝新纪元大學學院副校長文平强教授，是筆者在馬來西亞研究方面的導師，允许筆者使用該學院的收藏。感謝南方大學學院圖書館馬華文學館主任許通遠先生，是筆者在文學和電影方面的學術師兄，讓筆者有機會探索該中心的圖書館藏書。本目錄是在京都大學東南亞地域研究研究中心（CSEAS）主持的兩個研究項目的合作下完成的，這兩個項目是由兩位著名的馬來西亞華社研究學者領導的。感謝立教大學的舛谷銳教授，是研究馬華文學的主要學者，在馬來西亞收集了《蕉風》，並提供给立教大學和京都大學的研究使用。感謝北九州市立大學的筱崎香織教授，是馬來西亞華人歷史和社會的重要著作的筆者，幫助我們輸入和核對《蕉風》的目錄。感謝尚絅大學的黃蘊副教授也為《蕉風》的編目工作做出了貢獻，《蕉風》是通過她領導的一個研究項目購買的，現在保存在京都大學CSEAS圖書館。This catalogue lists the table of contents of 488 issues of the Chinese literary magazine Chao Foon from its first issue (November 1955) until its temporary cessation in February 1999. The following people and organisations have assisted in the preparation of this catalogue. I would like to thank them all. Professor Voon Phin Keong, Vice-Chancellor of New Era University College and my mentor in Malaysian Studies, allowed me to use the College's collection. Mr. Kho Tong Guan, the Head of the Malaysian Chinese Literature Centre at Southern University College and my academic senior in literature and film, gave me the opportunity to explore the library holdings of the Centre. This catalogue has been made possible through the collaboration of two research projects hosted at the CIRAS Centre of the Center for Southeast Asian Studies (CSEAS), Kyoto University, led by two renowned researchers on Malaysian Chinese studies. Professor Masutani Satoshi of Rikkyo University, a leading scholar of Mahua literature, collected Chao Foon materials in Malaysia and made them available for research at Rikkyo University and Kyoto University. Professor Shinozaki Kaori of the University of Kitakyushu, who is the author of a major work on the history and society of the Malaysian Chinese, helped me to enter the table of contents of Chao Foon. Huang Yun, Associate Professor at Shokei University, also contributed to the cataloguing of Chao Foon, which was purchased through a research project led by her and is now held in the CSEAS library at Kyoto University
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
