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
Effect of feed supplement with recombinant Insulin-like growth factors and vegetative ingredients replacing fish meal on the growth of Red striped snapper, Lutjanus erythropterus and Cobia, Rachycentron canadum
No full text本研究探討添加不同的重組類胰島素成長因子(Insulin-like growth factors, IGFs），與植物性原料替代魚粉飼料後對赤鰭笛鯛與海鱺幼魚的成長影響。研究分為兩個部分，分別是赤鰭笛鯛與海鱺兩種不同試驗魚種。以每100g飼料中添加重組類胰島素成長因子第一型、第二型(IGF-I, IGF-II）的大腸桿菌(E.coli）粉末0.5g、0.018g，以及酵母菌(Candida utilitus）的重組類胰島素成長因子第二型(IGF-II）粉末1.5g。其濃度為每1g 大腸桿菌含有 0.4、6mg 的IGF-I與IGF-II；酵母菌每1g含有0.4mg的IGF-II。
實驗一、二，探討赤鰭笛鯛飼料在含有60%魚粉，以及無魚粉與25%低含量魚粉的飼料組別中，添加不同重組IGFs。實驗一的結果顯示以全魚粉組中添加E. coli生產的IGF-I 0.5g的增重率153%，飼料效率83%具有較佳效果。實驗二的結果顯示在低含量魚粉組中含有E.coli生產的IGFs，其增重率為144、141%，飼料效率為75、71%，成長效果相當於全魚粉組試驗各組。
實驗三、四，探討海鱺飼料中添加不同重組類胰島素成長因子在60%魚粉組，以及植物性原料飼料試驗各組的成長影響。實驗三的結果顯示60%魚粉組中添加E. coli生產的IGF-I粉末0.5g的增重率168 %，飼料效率86%，相較於對照組有較佳效果。實驗四的結果顯示無魚粉組中以E. coli粉末生產重組的IGFs之增重率分別是86%、78%，相較於對照組的增重率64%，具有顯著性的效果；飼料效率各組在38－47%，各組之間未達顯著水準。The fact that insulin-like growth factors (IGFs) can enhance the growth of fish is clearly demonstrated. The experiments were conducted to study the effects of partially substituting fishmeal with vegetative ingredients and IGFs in diet of juvenile Red striped snapper, Lutjanus erythropterus and cobia, Racycentron canadum.
Experiment I investigated fish meal (60%) supplement to insulin-like growth factors of tilapia procreate form recombinant E. coli IGF-I, IGF-II and yeast(Candida utilitus) IGF-II in diet of juvenile Red striped snapper. The result of this experiment is that to feed the diet to add IGF-I contained in E.coli 0.5g per 100g diet has the best weight gain 153% and feed efficiency 83%.
Experiment II studied the effect of feed supplement with Insulin-like growth factors of tilapia procreate form recombinant E. coli IGF-I, IGF-II and yeast IGF-II and partially substituting fishmeal with vegetative ingredients in diet of juvenile Red striped snapper. The result of this experiment is that to feed the diet to add IGF-I contained in E.coli 0.5g per 100g diet has the best weight gain 144% and feed efficiency 75%.
Experiment III investigated fish meal (60%) supplement to insulin-like growth factors of tilapia procreate form recombinant E. coli IGF-I, IGF-II and yeast IGF-II in diet of juvenile cobia. The result of this experiment is that to feed the diet to add IGF-I contained in E.coli 0.5g per 100g diet has the best weight gain 168% and feed efficiency 86%.
Experiment IV studied the effect of feed supplement with Insulin-like growth factors of tilapia procreate form recombinant E. coli IGF-I, IGF-II and yeast IGF-II and partially substituting fishmeal with vegetative ingredients in diet of juvenile cobia. The result of this experiment is that to feed the diet to add IGF-I contained in E.coli 0.5g per 100g diet has the best weight gain 86% and feed efficiency 47%.目錄

Searching for Pure Strategy Equilibria in Bilateral Bargaining With One-sided Uncertainty
No full textThe problem of finding agents ’ rational strategies in bargaining with incomplete information is well known to be challenging. The litera-ture provides a collection of results for very narrow uncertainty set-tings, but no generally applicable algorithm. In this paper, we focus on the alternating-offers finite horizon bargaining protocol with one-sided uncertainty regarding agents ’ reserve prices. We provide an algorithm based on the combination of game theoretic analysis and search techniques which finds agents ’ equilibrium in pure strategies when they exist. Our approach is sound, complete and, in principle, can be applied to other uncertainty settings. Categories and Subject Descriptor
