(18(4):44-66)EXPERIMENTS ON PORTABLE POWER RICE CUTTER (SHOULDER SUPPORTING TYPE)
本省水稻收割作業,向以鐮刀刈割水稻為主要工具,工作效率既低,所需勞力又多,從而增加生產成本。且操作者必須彎腰始能割稻,工作極為辛苦,隨著教育之普及,和工業之發達,以及國民生活水準之日漸提高,農村青年多已走進工廠及企業機構,形成農村勞力日趨缺乏之現象。故每逢水稻收穫季節,農家往往因人手不足而耽誤農時,對產量及品質影響頗鉅。此一問題且有隨時間而日趨嚴重之勢,亟待解決。而大型聯合水稻收穫機之被採用,因受環境限制,尚有一段距離。本所有鑑及此,特購進日本製背負式動力割稻機二台,由於本省水稻之生理及物理性質與日本水稻品種頗有差異,故必須先予試驗研究加以改良,以期能符合本省農業環境。同時並接受農復會補助,以便擴大研究基礎,希望能於短期內推廣,以應此一過渡時期之需要。
1. According to the experiment, rice culms will be cut more effectually by a disk rice cutter with less cutting teeth, or the lesser the better.
2. This power rice cutter can cut 4 up to 6 rows of rice culms down each time (or 4 to 6 rice hills). The number of rows (or hills) of rice culms which can be cut by the rice cutter depends upon the number of culms in every single rice hill.
3. The losses of rice grains by shattering effect of using a rice cutter are different sharply with different rice varieties. For an example, the losses of Ponlai rice varieties which are usually lost the amount of grains from one to 2.3 times of grains by using a rice cutter compared with man power harvesting are considered the least of varieties.
4. The total working hours per ha. by using a rice cutter is ranged from 22 hours 12 minutes up to 39 hours 27 minutes, or 28 hours 26 minutes in average. The total working hours per ha. is much affected by the skill of the operator of course.
5. The fuel consumption is ranged from 12.5 litters up to 30.2 litters per ha. or 21.4 litters in average.
6. It is very clear, to cut down the rice culms is only one of important processes during harvest. The second one is threshing. The total expenses of the former process by using a rice cutter is NT 5.2 per litter with the wage of NT$ 10 per working hour, and the depreciation of the machine is not included in the above, the so called total expenses per ha
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
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.
