(6(3):47-52)AN EXPERIMENT ON THE DEMONSTRATION OF FERTILIZATION FOR WHEAT
No full text本示範自民國四十三年十月間開始至民國四十四年三月完成。為欲使農民明瞭三要素肥料配合施用的重要性，在臺中地區選定十處舉行本示範。每處同設有四處理，即氮肥區、氮燐肥區、氮鉀肥區、完全區等四種。肥料施用量參照臺中地區過去舉辦之三要素施肥標準量試驗成績而定。惟恐燐肥過少故將其提高，實際三要素施用量為、氣、燐、鉀100:80:60（公斤/公頃）。示範結果除一兩處差異較少外，餘均甚顯著。以氮肥區產量為100時，氮鉀、氮燐、完全區之指數為麥實107，108，132麥稈為124，106，142之順序。計每公斤氯化鉀可增產鮮態麥實6.8~9.5公斤，過燐酸鈣可增產0.8~1.6公斤。
再本示範對農民印象檢討如下：
(1) 播種後各處理間之差異均日見顯明，因此引起農民興趣，藉可使其澈底瞭解三要素肥料的重要性。
(2) 使用鉀肥的增產量均極顯著。農民未明鉀肥功效者，由此當可獲得深切瞭解。
(3) 肥料配合適當與否，非但可影響產量增減，即其成熟收穫期之遲早亦大受影響。僅使用硫酸錏區的成熟期顯明的較其他各區為遲。
(4) 燐肥對小麥之初期發育如發芽、分蘗及促進成熟等之肥效，均引起了農民的注意。
From October 1954 to March 1955, a demonstration on the application of NPK fertilizers on wheat has been carried out in order to show the importance of using phosphorus and potassium fertilizers in combination with nitrogen, a fact which is not well recognized by local farmers.
Ten demonstration fields were selected in the Taichung, Fongyen, and Wufong districts. Four treatments, namely, N, NP, NK, NPK, were laid in each demonstration and the amounts of N, P2O5, & K2O fertilizers applied were respectively 100:80:60 kg/ha. The average increase of yields can be computed into the following indexes: for grain, N 100, NK 117, NP 108, NPK 132. for straw, N 100, NK 124, NP 106, NPK 142.
Each kilo of potassium chloride can produce 6.8 to 9.5 kilos of grain and each kilo of superphosphate can give 0.8 to 1.6 kilo of grain.
This demonstration evidenced the following facts to farmers:
1. The differences among 4 different treatments were quite significant in most localities. Farmers were deeply impressed and had a clear understanding of the purpose of the demonstration.
2. The increase of grain and straw yields due to the application of potash were most significant in every locality. The farmers have gained a better knowledge of the effects of potash.
3. Whether the three elements are used in a correct proportion or not, it may affect not only the yield of wheat but also the time of maturity. In this demonstration, the N plots were still immature while NPK plots were ready for reaping.
4. The phosphatic fertilizer can improve the development of plant in the first stage of growth and can hasten the maturity. Farmers were much interested and paid great attention to this effect
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.
