No full text為闡明高溫桔之菌絲生長、發菇等生理與栽培下種量、栽培適期及加工等有關資料，乃從事以下各種試驗，結果如下：
(一) 菌絲生長以30℃最好，15℃以下及40℃以上，15天內不會生長，39℃為菌絲生長最高臨界溫度。
(二) 菌絲在PH5.1~7範圍均能生長良好，至PH4及PH10時，則生長顯著不良。
(三) 堆肥水份含量在56~79％範圍內，菌絲均能正常生長，其中以56％左右生長最快，46％以下則生長不良。
(四) 供試培養基中以馬鈴薯堆肥洋菜培養基生長最好，堆肥洋菜、玉米堆肥洋菜及玉米洋菜三種次之，Czapek培養基最差，菌絲亦稀弱，馬鈴薯洋菜培養基生長慢，但菌絲濃，且在菌絲上極易形成小桔體。
(五) 小子實體(Pinhead)或菇蕾(Primodium)之發生以30℃最多，25~35℃下亦可發生，但數量較少，20℃以下，則幾乎無法形成。
(六) 在25、30、35℃三種溫度下，相互變溫培養，在上述範圍內無論高溫培養後移於低溫培養，或反之，均能形成小子實體或菇蕾。
(七) 子實體之形成與光線之關係不大，在0-1000Lux下均能出拮，為管理方便以50-100Lux之光照較為合宜。
(八) 本試驗用糙米培製之菌種，每坪份折合用1、2、4、8、16瓶(350g)等處理，經栽培統計分析結果，除用1瓶／坪者，產量顯著較差外，其他均無顯著差異。在實用上似應用2瓶／坪較為經擠，但如為提早出菇，或減少害菌寄生機會，增加菌種用量，亦為一可行之方法。
(九) 本省氣候下，一般4~10月間均可栽培，與一般洋桔可以配合作週年栽培。
(十) 高溫菇據國內外學者之鑑定確屬Agaricus bitorquis，再經生物及加工食用有關試驗資料，確定可供食用。
(十一) 加工冷凍乾燥成品不亞洋菇（圖五），製成罐頭則切片為適，製成紐粒者，因此菇有一層薄膜，影響外觀至大。
In order to closely examine a) the effect of environmental factors on mycelial growth and fructification, b) the relationships between the yield and both the rate of spawning and season of cultivation, as well as c) the quality of processing product of a new mushroom,which has been identified as Agaricus bitorquis by ATCC, many experiments were carried out and the conclusions are described as follows
1. The optimum temperature for mycelial growth was 30°C; no growth from the innoculum was observed at the temperature lower than 15°C or upper than 40°C in 15 days; the highest critical temperature. for mycelial growth was 39C.
2. The mycelia grew well in the pH range of 5.1 to 7.0, but poorly when the pH value was lowered to 4 or raised to 10.
3. Normal rnycelial growth was obtained when the water content of the compost was strikingly adjusted to 56-79%, with an optimum at 56%, but the growth was limited when the water content was lower than 45%.
4. Potato-compost-dextrose agar medium was excellent for mycelial growth among the media being tested, both the compost agar medium and corn agar medium were suboptimum and the Czapek agar medium was bad for mycelial growth. The mycelia grew slowly, but easily developed primordia on PDA.
5. A great number of primordia or pinheads were obtained on agar media if the culture was put at 30°C, however only a few primordia were observed when the temperature was lowered to 25°C or raised to 35°C. The primordium could hardly be observed if the culture was put at the temperature lower than 20°C.
6. The formation of primordia was not evidently affected by change in temperature during inocubation in the range of 25 to 35°C.
7. The initiation of fruiting was not closely related to light. The culture could initiate fruiting on agar media when it was subjected to different light intensity of 0-1000 Lux. However practically it was usually exposed to 50-100 Lux for the convenience of the management of cultivation.
8. With the respect to the experiment on the relationship between the yield and the rate of spawning, it was observed that there was no significant difference in yield when the compost was spawned at the rates of 2 to 16 bottles (350 gram/bottle) per pin (ca. 3.24m2) . In practical application, the most economic spawning rate is 2 bottles of spawn per pin.
9. From April to October the climatic conditions are suitable for cultivation of Agaricus bitorquis in Taiwan.
10. The quality of dehydrated product of the new mushroom A. bitorquis obtained by subjecting the slices of fruit—bodies to quick freezing and drying could be compared with that of dehydrated mushroom of A. bisporus. However, the canned product with whole mushrooms of the former was not so good as those of the latter due to the presence of thin membrances on the pileal surface of the former. It would he better if the mushrooms of the former were cut into slices

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
