(15(4):41-48)A COMPARATIVE STUDY OF SOME RICE VARIETIES OF TAIWAN WITH REGARD TO FERTILIZER RESPONSE AND NUTRIENT UPTAKE (PART II)
No full text1. 本試驗採用五種本省主要水稻品種，乃新竹 56 號、臺中 65 號、嘉農 242 號、矮腳尖及臺中在來 1 號，民國 54 年一、二期作於羅東、桃園、彰化三處設置田間試驗，以究明不同品種對三要素肥料之產量效應及養分吸收特性。
2. 品種間谷及藁之產量有顯著的差異而高產量之品種，其谷藁比亦概為大。各品種稻谷產量之高低順序依次為矮腳尖＞臺中在來 1 號＞嘉農 242 號 ＞ 新竹 56 號 ＞ 臺中 65 號。
3. 氮肥對各品種之增產效果極為顯著而以一期作較二期作為大。一期作矮腳尖及臺中在來 1 號之稻谷產量隨氮肥增施而遞高，但嘉農 242 號、新竹 56 號及臺中 65 號卻以每公頃 90 公斤氮得最高而增施至 120 公斤氮時反有減產之趨勢。由於品種與氮肥之間有顯著的交感作用而需肥量有差，故決定施肥量時品種因素似亦有考慮必要。
4. 各品種之谷藁比，隨氮肥之增施而遞減，但在一期作氮肥反應較大之矮腳尖及臺中在來 1 號，其谷藁比之遞減程度較為小。
5. 磷肥及鉀肥對各品種之肥效，本試驗均不顯著。
6. 供試品種之要素含量，矮腳尖及臺中在來 1 號稻谷中之含氮量較高但藁稈中之要素含量差異較小，故品種之稻谷產量高低與要素含量似無直接相關。
7. 矮腳尖及臺中在來 1 號兩高產量品種之三要素吸收量遠較三種供試蓬萊品種為大。因其需肥量大，宜多施肥料以提高產量。
Three ponlai and two native rice varieties of Taiwan, including Hsinchu 56, Taichung 65, Chianung 242, Aichiaochien and Taichung Native 1, were selected for comparison of their response to N,P,K fertilizers and nutrient uptake. The combinations of five rice varieties and eight fertilizer treatments were laid out in a split plot desin at each site of Lotung, Taoyuan and Chunghwa for the two crop seasons of 1965. The results obtained are summarized as follows:
1. The differences of the yield among the testing varieties were very signi-ficant. The order of grain production was as follows: Aichiaochien>Taichung Native 1>Chianung 242>Hsinchu 56>Taichung 65. High yielding variety has a fairly great ratio of grain-straw in the 1st crop, but there is no such a relationship in the 2nd crop.
2. Application of nitrogen has a substantial increase in the yield of each variety. The effect is greater in the 1st crop than in the 2nd crop. In the 1st crop, the increments of grain yield of Aichiaochien and Taichung Native 1 follow with increase of nitrogen, while those of the three ponlai varieties are the highest at 90 kg N per ha. and tend to decrease at 120 kg N per ha. The marked interaction between nitrogen fertilizer and the varieties in the 1st crop (Table 2 and 3) indicates the importance of varietal factor on fertilization problem.
3. The grain-straw ratio of each variety decreases with increase of nitrogen. However the degree of declining is smaller with those varieties which have greater incremet of grain yield in the 1st crop.
4. The response of the varieties to P and K fertilizers at three localities was not distinct.
5. There is no significant difference in N,P and K content of straw among the testing varieties, though N content of Aichiaochien and Taichung Native 1 in dry grain is rather higher. The yield of each variety is apparently not differenciated by nutrient content of the rice plants.
6. The big variation of the production among the varieties may be attributed to their magnitude in the absorbing capacity of the elements. Two native varieties of Aichiaochien and Taichung Native 1 have notable amount of N,P and K in the harvested materials. This indicates that high yielding variety needs mLch fertilizers to produce more
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.
