No full text為明瞭新育成推廣之長粒型秈稻品種嘉農秈6.8.11號之種子休眠性，適當的稻種預措方法及脫粒性等以謀發揮其優越之生產潛力，減少損失，於63年二期作至64年一期作在本分所進行本試驗。結果摘錄如下：
1. 嘉農秈品種具有長短不同的短期休眠性，嘉農秈6號之休眠期最長，約為兩週左右，嘉農秈8號次之，約為7天前後，而嘉農秈11號似未具休眠性；故嘉農仙6.8號之稻種在收穫乾燥後至少須分別存放兩週或一週以上，而嘉農秈11號之稻種亦應充分乾燥後方可供下期作播種之用。
2. 稻穀收穫後，須充分乾燥至含水量在13度以下，一期作在播種前須浸種48~72小時，催芽24小時；而二期作應浸種24小時，催芽24小時，方能確保稻種之發芽車與發芽整齊度。
3. 嘉農秈三個品種均屬於較易脫粒之品種，尤以嘉農秈8號最易脫粒，嘉農秈11號次之，而以嘉農秈6號較難脫粒；又嘉農秈6.8號有隨著成熟度之增加而愈易脫粒之現象，應適時採收以減少田間損失率；但嘉農秈11號具有愈成熟愈不易脫粒特性，故其採收延誤時應無嚴重之損失。
This experiment was aimed to study the grain dormancy, seed pretreatments and
shattering habit of new-improved long grain Indica rice varieties Chianung sen 6, 8 and 11 in order to exploit their full potentiality and reduce the possible losses. The trial was conducted from the second crop of 1974 to first crop of 1975 at the Chia-yi Agricultural Experiment Station. The results are summaried as follows:
1. The dormancy period of Chianung sen varieties differed significantly. Chianung sen 6 appeared to have the longest dormant period of two weeks and Chianung sen 8 had dormant period of 7 days, while Chianung sen 11 had no appreciable period of dormancy. Hence, the grains for seed purpose should be stored for one or two weeks before seeding for Chianung sen 6 and 8. The grains of Chianung sen 11 should also be properly dried.
2. In order to obtain satisfactory and faster germination, the grains of Chianung sen varieties should be dried to the moisture content of less than 13 percent and soaked 48-72 hours with presprouting treatment of 24 hours in the first crop season. It should also be soaked 24 hours with 24 hours of presprouting in the second crop.
3. The degree of grain shattering of Chianung sen varieties was in the order of Chianung sen 8, 11 and 6, i. e. Chianung sen 6 gave greater resistance to shattering than Chianung sen 11 and 8.On the other hand, the shattering resistance of Chianung sen 6 and 8 decreased with the progress of ripening, but the opposite was true with Chianung sen 11. Thus, Chianung sen 6 and 8 must he harvested at the proper stage of maturity, while the losses from shattering may be light for Chianung sen 11 even if it is harvested over-ripe
RESPONSE OF THE ABILITY OF RICE SEED GERMINATION TO HERBICIDES
No full text由於本省工商業之急速發展，導致大量農村勞力外移，而此農村勞力缺乏問題有日趨嚴重的傾向，因而省工的水稻直播栽培法，已日漸為廣大農村所採用。據全省性水稻直播栽培示範結果指出，可節省勞力三分之一左右，增產5.8~15.9%，純收益增加達新臺幣3,011元／公頃(1),，故水稻直播栽培法被認為今後可行的一種省工水稻栽培法。但直播水田雜草發生種類與數量常較移植田為烈，必須
以殺草劑除草方能達到省工目的。目前省內使用於直播水田的殺草劑僅掃丹與馬上除二種。
雖然有關直播水田殺草劑的試驗，國內外可責參考的資料文獻不少，但殺草劑對直播水稻種子發芽及幼苗生長之影響，卻少有資料。在大豆(3.5.6)、玉米(2.7)，及其他許多作物，同一品種對不同殺草劑，或不同品種對同一殺草劑，往往頭示不一致的反應情形，故本試驗的目的，仍在測定不同水稻品種在不同殺草劑處理下，稻種發芽所受之影響，以供直播水田施用殺草劑除草時參考。
Seventeen japonica type rice varieties and twenty-three indica type rice varieties were used to test the response of seed germinated ability of rice varieties to four different herb icides, which were TOK, Saturn, Machete and MO 338. The rate of application of these herbicides were at 3.0? 15.0 and 30.0 kg/ha a. i., respectively, excepted Machete was at the rate of 1.5, 7.5 and 15.0 kgJha a. i. The results were as following:
1. Rice seed germination was only depressed by TOK severely, the influence of other three herbicides were on the order of Machete, Saturn, and MO 338.
2. The variation of seed germinated rate between different varieties was a little lower than different herbicidal treatments.
3. The rice seed germinated ability of indica type rice varieties were lower than the japonica type rice varieties.
4. According to this experiment, Kaoshiung No. 64, Kao-sen-yu No. 12, Mudgo and Hasawi were the most sensitive varieties to above four different herbicides
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
