    本試驗係于民國40年起分別在臺北、臺中、臺南與臺東四地舉行,至民國42年完成。茲將三年來試驗成績總結於後。 1. 肥料處理對于小麥生育狀況的影響:氮與鉀的施用可以促進小麥植株高度的增加,但前者以臺北地區為例外,後者以臺東為例外。燐對于植株高度的效應除臺北外,其他地區均不明顯。氮與燐的施用對于小麥穗重的效應不顯明,而鉀肥則反之。此外臺北地區之小麥穗重每因施用燐肥而增加。氮的施用除臺北外均可促進穗長的增長,燐與鉀則不明顯。 2. 肥料處理對于小麥收量的影響:若以無氮區、無燐區與無鉀區之小麥產量作為100,與各該施用區比較時,各地最高的增產百分比為: N 臺北10%,臺中60%,臺南27%,臺東16%。 P2O5 臺北58%,臺中4%,臺南20%,臺東11%。 K2O 臺北46%,臺中27%,臺南13%,臺東14%。 兩要素間連應的影響:在臺北地區氮與磷或氮與鉀均為負連應,僅磷與鉀為正連應。其他三地區所有之連應均為正號,其中尤以臺中最為顯明。由此顯示栽植小麥時之要素適量比的重要以及臺北地區氮肥施用法必須加強研究。 3. 小麥三要素適量比的決定:就本試驗結果推測各地小麥三要素適量比與其經濟的施肥適量比如下: In the past years, experiments were mostly made on the fertilizer requirment of paddy rice and sugarcane. Few data are available for those other than these two crops. Recently, owing to the increasing cultivation of winter wheat by local farmers, a recommandation concerning the rational rate of application of fertilizer for this crop is urgently in need. The purpose of this experiment is to ascertain the optimum fertilizer ratio for winter wheat in different districts of this province. This experiment has been conducted in the following localities, Taipei, Taichung, Tainan, and Taitung, in the past three years since 1951. Its results may be summarized as follows: 1. Effect of fertilizer treatments on the growing status of winter wheat; It has been found that application of nitrogen has a favorable effect on the hight of wheat plant and length of ear except in Taipei district. Application of potash will cause an increase in height of plant and weight of ear. However, the response of potash to the height of plant is not so obvious in Taitung district. Application of phosphorus has striking effect on the height of plant and weight of ear in Taipei district, but it does not occur in other three localities. 2. Effect of fertilizer treatments on the yield of wheat; The maximum yield increased due to the application of N, P2O5, K2O has been computed as following table, provided that the yield of wheat in the plot of no nitrogen, no phosphorus and no potash as 100, respectively. Generally speaking, the effect of interaction between two elements, namely, nitrogen and phosphorus, nitrogen and potash, and phosphorus and potash has a positive effect on the yield of wheat throughout this experiment except in the district of Taipei where the interaction between nitrogen and phosphorus, or nitrogen and patash showes a negative effect. It emphasizes the importance of rational combination of the three essential elements for raising wheat and the necessity of reconsideration of the method for applying nitrogenous fertilizer in Taipei district. 3. A recommandation concerning the optimum fertilizer ratio for wheat; According to this experimental data, a recommandation concerning the optimum fertilizer ratio for winter wheat in different localities of this province has been suggested as follows; 4. Based on the farmer’s profitable view point, a suggestion concerning the economical fertilizer ratio for wheat has also been submitted

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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 text
    In 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.
