Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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

Study on the Color Increasing of Sekkan Fruit (Citrus sinensis) Treated with Calcium Carbide
No full text本試驗係於56年10月間，在本分所進行，並利用冷藏與室內貯藏，以比較催色後，水分之消失、著色程度及品質之影響。茲將試驗結果，摘要如下：
1.雪柑水分消失與貯藏日數
雪柑不論於室內或冷凍庫貯藏時，應以電石30公克燻一日，不但着色鮮豔，且水分消失量亦小。如欲保存果實品質，應冷藏於3-5℃低溫，較室內貯藏，可延長三週之久。
2.雪柑催色後著色情形
如以雪柑本身，着色快慢與好壞論，用電石20或30公克燻一日，室內貯藏，着色最好且快，冷凍庫內貯藏著色不衰，但可延長果實之貯藏日數。
3.電石催色對雪柑品質之影響
應用電石催色，燻一日者於冷藏庫貯藏後，調查結果，所佔優良果數百分率高。同時電石用量以20公克對品質保護，有直接的效果。
This experiment was carried out at Fengshan Tropical Horticulture Experiment Station October, 1967. Sekkan fruits were treated with Calcium Carbide (CaC2) for one and/or two days then stored in both room temperature and cold storage in order to ascertain the increasing of color, lose of weight and effect of the fruit qualities were studied. The results may be summarized as follows:
1. The lose of weight and increasing storage life:
Either in room temperature or in cold storage, better color and lower percentage lose of weight were recorded in 30 grams of CaC2 for one day treatment. If the fruit in good condition and stored under 3-5℃, the storage life could be lasted for shunt three weeks.
2. Increasing the color of the fruit:
It was so fast to force the color increasing treated with CaC2 at 20 or 30 grams oneday under room temperature hut none in refrigerator. Fruit storage life was shortened in cold storage also.
8. Effect of fruit qualities:
Best quality and higher percentage of excellent fruits treated with 20 grams of CaC2 one day in cold storage were obtained as compared to the others
