(26(2):147-150)PRELIMINARY OBSERVATION ON THE EFFECT OF “FERTILAID” ON PADDY RICE
No full text「肥田利地」係臺灣農產品外銷市場研究中心於日1974年自美國引進的一種有機活性劑(Organic activator)肥料，施用後能改良土壤質地，而有利於農作物之生長與產量的提高。本試驗乃觀察肥田利地施用後對水稻生長發育與稻穀產量之影響，初步結果顯示稻田施用肥田利地並不能獲致增產效果。導致肥田利地表現欠佳之原因，係由於肥田利地施用區之分蘗能力與每株穗數較單施化學肥料區為差所致。但由於肥田利地之施用可提高有效分蘗率與減輕穗頸稻熱病之罹病率，故若能改良其施用方法，將可使稻穀產量獲得提高。
‘Fertilaid” is an organic activator which was introduced from United States by Taiwan Agricultural Products Export Market Research Center in 1974. It has been reported that “Fertilaid” could improve soil structure and increased the growth and yield of various crops. This experiment was conducted to observe the effect of “Fertilaid” on the growth and yield of rice in Taiwan. Preliminary results indicated that chemical fertilizer alone treatments showed high grain yields over that of “Fertilaid” treatments, the combinations of chemical fertilizer and “Fertilaid” treatments further increased the yields over the “Fertilaid” alone. The “Fertilaid” application treatments caused the decrease of grain yields that appeared to be due to the decrease in either tillering ability or number of panicles per plant. Since the “Fertilaid” can increase the percent of effective tillers and reduce the infection rates of panicle-neck blast disease, therefore, the grain yields of ‘Fertilaid” treatment will be increased if the methods of ‘Fertilaid” application can be improved
(20(1):41-43)PRELIMINARY OBSERVATION ON THE AGRONOMIC TRAITS OF RICE VARIETIES INTRODUCED FROM SEVERAL AFRICAN COUNTRIES
No full text本分所於民國59年從事非洲引進稻之適應性觀察。初步結果顯示多數引進稻之株高、穗數及生育日數均不甚理想，惟其穗長、穗重、一穗粒數及谷粒之形狀與大小等，則頗有可取之處，似為良好之雜交育種材料。
One hundred and fifty six rice varieties introduced from several African countries, Iran, and Domenica were evaluated for their major agronomic traits in the first and second crops of 1970 at the Chiayi Agricultural Experiment Station. Preliminary results indicated that plant height, number of panicles per hill and growth duration of most introductions were unsatisfactory. However, the length of panicle, panicle weght, number of grains per panicle, and the shape of grains of these varieties appeared to be superior to local commercial varieties. It is, therefore, suggested that most of these introduced varieties can be used as breeding materials for improving local varieties
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
