Development of Mass Production of VAMF Inoculum by Sand Culture
No full text內生菌根菌(Vesicular-aibuscular mycorrhizal fungus, VAMF)證實與許多作物根系具有親和主，當VAMF感染作物根部形成內生菌根時，往往能產生有益效應，促進根群發育，增加根部對磷肥等要素之吸收能力，促進植株生長。惟內生菌根菌是一種活物寄生真菌，目前尚無法在文工培養基上大量繁殖，接種盆栽宿主植物繁殖內生菌根菌接種源是目前唯一可行途徑。除宿E外，土壤（栽培介質）因子、環境因子等亦可影響內生菌根菌之繁殖。本分所建立之內生菌根百接種源生產體系，分為三個步驟：（一）以多年生百喜草盆栽保存純種，（二）以盆栽玉米繁殖貝種，（三）以大型栽培床之玉米（或營多藤）大量繁殖內生菌根菌，經收集培養土（含宿主根長）風乾裝袋而成接種源。在實際應用上，採用苗期接種，培養洋香瓜內生菌根苗，當內生菌根苗移植於本田，即可將菌種帶到田間，發揮內生菌根之功能，表現其有益效應。
The vesicular-arbuscular mycorrhizal fungus was proved to have the compatibility with root systems of many crops. Formation of VA mycorrhiza in root systems of crops infected by VAM fungus could arise beneficial effects, i.e. promoted the growth and development of root systems, increased the absorption of soil mineral elements, enhanced the top growth of crops. Up today, the common method for propagation of VA mycorrhizal fungi were pot culture because they were obligate symbionts. Factors affected the propagation of VA mycorrhizal fungi in pot culture included host plants, soil (culture media), and environment. We developed a procedure for propagation of VAM fungus inoculum as follows: 1. maintaining the pure VA mycorrhizal fungus in pot culture of bahiagrass, 2. propagation of VAM fungus in pot culture of corn, 3. mass production of VA mycorrhizal fungus inoculum in sand bed culture of corn or beggarhce, 4. air-drying and bagging the harvested culture soil including the segments of infected root systems of host plants and fungal chiamydospores. Method for application of VA mycorrhizal fungus to field was by transplanting mycorrhizal seedlings of muskmelon pre-inoculated with infested soil in plastic net house. When the mycorrhizal seedlings were transplanted to the field, mycorrhizal root systems could show beneficial effects to muskmelon production
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.
