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
(11(2):21-36)A CHEMICAL SURVEY ON THE NUTRITIVE CONSTITUENTS OF PADDY RICE IN TAIWAN
1. 為提供稻米成份有關資料,於民國49~50年就省產水稻粳米代表品種進行糙米之營養成份調查;49年度調查為蓬萊水稻36品種74個標本之一般化學成份分析,50年度為水稻粳米70品種177個標本(蓬萊44品種136個,在來26品種41個)之水份、灰份及蛋白三成份定量,。
2.分析成績顯示,各成份數值以產地場所為單位而集中之傾向,可見地域性因素較品種因素對營養成份含量影響為大。
3. 水稻粳米蛋白含量,無論蓬萊種或在來種,一率發現二期作較一期作者為高。二年間總平均一季9.01%,二季9.75%,約超出百分之八。
4. 在來種蛋白量較蓬萊種者每季為高。50年度全年平均在來種10.04%,蓬萊種8.89%,高出一成以上。同時灰份含量亦同,在來種1.6%,蓬萊種1.52%,略高出百分之五。
5. 蛋白及灰份含量略示其間有相關關係模樣,但因所使用之標本不多,未甚瞭然,俟日後試驗調查始得斷定。
In order to make an information concerning the food value of paddy rice in Taiwan, a chemical survey on the nutritive contituents of brown rice w s made. The common chemical constituents analysis on the 74 samples of Ponlai rice (36 varie-ties) and the nutritive ingredients analysis, namely the determination of moisture, ash and protein contents, on the 177 samples of paddy rice (70 varieties) were carried out in 1960 and 1961, respectively.
The results of analyses were shown in Table 1~4. It was found that the contents of nutritive constituents were mainly affected by the factor of locality and little influ-enced by that of variety.
The mean of protein contents in 1961 was 8.89 per cent with the Ponlai variety and 10.04 per cent with the native variety, i. e., the native rice was superior in food value than the Ponlai rice so far as the protein content concerned.
It was also found that the protein content of the second crop was higher than the one of the first crop, either with the Ponlai or with the native variety.
There was certain correlation observed between ash and protein contents, but as the number of samples used by us was too few to make a conclusion
(25(1):64-72)STUDIES ON THE NUTRIENTS VARIATIONS IN GROWTH STAGE OF CORN AND ITS VALUE IN ECONOMIC ASPECTS
1. 為提供玉蜀黍合理栽培利用方法,自民國61年秋至63年春季二年間,先後在臺中霧峰及嘉義,以密植一疏株法進行玉蜀黍田間栽培試驗,並就疏株所得各期收穫物(I~Ⅲ期青草,IV期玉米)進行化學成份分析比較。
2. 各期所得試驗成績數值,概見於表一~表四。在62年春~63年春季本試驗所得結果,如表六。至於玉蜀黍生育中成份變化情形,如表七。
3. 試驗結果指出密植栽培可獲多收,增產營養成份50%以上,但密植亦可影響植物體木身生產能力。
4. 分期收穫成績顯示,玉蜀黍在生育二個月時,其成長異常迅速二故可考慮:(1)早收為青飼料用,以增加栽培次數而利土地週轉使用,或以(2)密植一疏株方式栽培,兼得青草及玉米飼料而提高單位面積收益。
5. 在本密植一疏株法試驗,由61年秋作預備試驗與63年春作加強試驗成績,尚無法看出若何施肥效應,原因何在,尚不得而知。
6. 由田間試驗觀察及所得試驗結果,發現充裕之水份供應及日照乃為王蜀黍栽培上重要因素,此生理上問題尚待今後詳細研究。
In order to offer an information concerning about the nutrients variations in growth stage of corn (Zea maize), more over, to present an advantageous cultivation accompanied with useful land utilization, studies were conducted in 1972 autumn~1974 spring. A Close-spacing and Thinning cultivation method was applied and four of periodical products in every crop were subjected to chemical analyses. The results of each crop were shown in Table 1~4.
It was found that an extremely rapid growth of corn appeared two-month after germination and it was recognized that the maximum nutrients formation of corn was got in this period.
With the Close-spacing and Thinning method, one could obtain about two folds production of protein and above one and a half production of other nutritive constitunents, including calories, when compared with ordinary cultivations. The details were shown in Table 6.
The data of experiments showed valuable of Close-spacing and Thinning method, even though, unfavourable effects of Close-spacing were also observed, therefore, too tight Close-spacing is undesirable from the points of view, such as reduce in yield, needs of much seeds and labours, and so on. The moderate design for the Close-spacing seems to be that starting from 30×15 cm to 60×30 cm in row and space distances via once thinning process.
At last, it should be emphasized that enough moisture contents of soil is the principal factor in corn cultivation, and it becomes more important for a Close-spacing plantation
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
(16(4):62-67)A CHEMICAL SURVEY ON THE NUTRITIVE CONSTITUENTS OF PADDY RICE
民國53、54年就蓬萊水稻代表品種臺中65號及在來水稻臺中在來1號等八品種,進行糙米之營養成份調查;本調查乃著重灰成份之測定,分析項目計有水份、灰份、蛋白、純蛋白及鈣、磷、鐵、鉀等,所得成績見於表1~表4。
調查結果略示:如前報所述,在來種比蓬萊種水稻其蛋白含量大,又無論秈種或稉種二期作概較一期作者蛋白量高,並發現稻米蛋白可謂全由純蛋白構成之。
就本省最重要蓬萊及在米水稻代表品種臺中65號及臺中在來1號而言,其主要營養成份如以乾物百形比表示,即略為蛋白10.5%、灰份1.5%、鈣25mg%、磷350mg%、鉀260mg%、鐵2.3mg%等。
蛋白與灰份偕灰成份間之相互關係,經調查結果乃知蛋白與灰份間有正之相關關係,而灰成份中僅鉀乙成份與蛋白具成正相關。
A chemical survey on the nutritive constituents of paddy rice in Taiwan was conducted in 1964~1965. The main varieties of rice, such as Taichung No. 65 and Taichung Native No. 1 etc., were treated and chemical analyses were made on brown rice.
The result was shown in Table 1~4.
The amounts of the principal nutritive constituents of rice were in the neigh bourhood of 10.5% with protein, 1.5% with ash, 25 mg% with Ca, 350 mg% with P 260 mg% with K and 2.3 mg% with Fe on oven-dry basis, respectively.
The variation in protein contents with variety and season was found same as in the former report, i. e., the native variety was richer in protein and the protein content of the second crop was superior to that of the first crop.
It was found that the protein content was in positive correlation with the ash content. With minerals, only the content of potassium positively correlated with that of protein, even though, the contents of potassium and phosphorus both correlated with the one of ash significantly
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
