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

GENETICS AND PLANT BREEDING
SEMESTER: January-June, 2016A research was conducted by using six F5 and three F8 populations generated through inter-varietal crosses of Brassica rapa L. and grown in the experimental farm of Sher-e-Bangla Agricultural University, Dhaka, during November 2015 to February 2016 to study the variation in different characters, correlation between pairs of different characters and the direct and indirect effects of different traits on yield of the F5 and F8 materials to select high yielding and early mature plants. Considering genetic parameters, comparatively phenotypic variances were higher than genotypic variances for all characters studied. Number of primary branches per plant, number of secondary branches per plant, length of siliqua, number of seed per siliqua, thousand seed weight and yield per plant showed least difference between genotypic and phenotypic variance. High phenotypic and genotypic co-efficient of variation were found on number of secondary branches per plant, number of siliqua per plant, thousand seed weight and yield per plant. The highest yield per plant (11.95 g) was found in BARI sarisha-6×BARI sarisha-15 S1F5. The advanced line BARI sarisha-6×BARI sarisha-15 S2F8 matured early (80.33 days) and produced moderate yield (4.35 g/ plant). The highest GCV (79.55 %) and PCV (79.62 %) were observed in number of secondary branch per plant. Number of siliqua per plant showed high heritability (96.69%) along with high genetic advance (88.55) and high genetic advance in percentage of mean (73.66%). The highest genetic advance (88.55%) was found for number of siliquae per plant. Moderate heritability (39.30%) with low genetic advance (3.06) was found for days to maturity. Yield per plant had non-significant and positive correlation with days to maturity, plant height, number of secondary branches per plant, number of siliqua per plant, siliqua length and thousand seed weight. The path co-efficient analysis revealed that number of siliqua per plant had the highest positive direct effect followed by number of seed per siliqua, number of secondary branches per plant and days to maturity. Populations of four most promising lines with higher yield were selected from different nine crosses of the F5 and F8 populations of Brassica rapa L

ENTOMOLOGY
SEMESTER: JANUARY-JUNE, 2015In order to study the damage loss assessment and management of rice weevil (Sitophilus oryzae L.) in wheat and maize grains in storage, experiments were conducted in the laboratory of the Department of Entomology, Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from May to October 2014. Results revealed that no loss of wheat and maize grain weight during storage was found in T2 (Naphthalene 5 g/kg of stored grains) where highest loss of grain weight was found by T3 (Neem oil 5 ml/kg of stored grains) for wheat stored grain and T5 (Black pepper 5 g/kg of stored grains) for maize stored grain. In case of mortality of rice weevil, results also indicated that T2 (Naphthalene 5 g/kg of stored grains) showed 100% mortality of rice weevil where lowest mortality was found from T3 (Neem oil 5 ml/kg of stored grains) for wheat stored grain and T5 (Black pepper 5 g/kg of stored grains) for maize stored grain
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
