Current status of management, production and stand structure of managed Moso Bamboo forests in Kagoshima Prefecture, Japan
Get PDF本研究は，鹿児島県の管理モウソウチク林の生産状況と林分構造の現状を明らかにすることを目的とした。調査として姶良市とさつま町の2カ所の管理モウソウチク林における林分調査と竹林管理者に対する聞き取りを行った。その結果，管理者の高齢化に伴い竹林での重労働が困難になっている一方で，林分調査の結果（平均稈密度3, 917本/ha，平均DBH 12.0 cm，新竹率30.6％，稈の一様分布）と施業現状から，対象竹林における管理（密度，施肥および防災管理）は現在も続けていることが考察された。一方で，国内需要の低迷などの影響から，竹材・タケノコの生産量は10年前と比べて顕著に低減していた。このことは調査林分における稈密度が過去より増加したことと一致していたことに裏付けられていると考えられた。今後，竹林は委託管理など新たな管理主体により管理を継続する場合，今までの竹林管理で集積されてきた技術，竹林生産などを参考情報として整理・記録する必要があると考えられる。また，作業がしやすい低密度かつ一様分布という林分の特徴を示す管理竹林を対象とした林業機械の開発と導入が，作業の持続性と省力化を改善する一つの選択肢として検討する価値があると考えられた。The purpose of this study was to clarify the status and problems of the management and stand structure of the Moso bamboo forests in Kagoshima Prefecture. We conducted an interview survey with 2 bamboo forest managers and investigated the stand structures in their bamboo forests, which are located in Aira City and Satsuma Town. It was revealed that density control, fertilization, and mowing in the bamboo forests are carried out regularly. As the result of this management, the stand structure of bamboo forests was revealed as: average culm density 3, 917/ha, average culm diameter at breast height 12.0 cm, 30.6％ of 1-2 years culm; the culm stand was close to regular distribution. However, due to the sluggish demand for bamboo products and the aging of forest labour, the production of bamboo raw materials, especially bamboo shoots, has decreased significantly compared to 10 years ago, which was also considered to be connected with the increase in the density of bamboo culm in the bamboo forests. We concluded from these results that it is necessary to organize and record the information and methods related to management and production accumulated in the long term of bamboo forest management to ensure the sustainability of production, especially if management passes to a new entity in the future. Developing and introducing forestry machines was also expected to be an effective way to save labor costs in a bamboo forest connected with its relative low culm density and regular culm distribution
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
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.
