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
Cloning and analysis sequence of Bacillus thuringiensis ENTOMOCIDUS INA 288
No full textB. thuringiensis has been studied worldwide over the past decades, mainly because this gram-positive
bacterium produces significant amounts of crystal protein toxic activity against economically important insect
larvae. Most strains of B. thuringiensis produce delta-endotoxin crystals toxic to lepidopteran insects such
moth. But some strains of B. thuringiensis produce delta-endotoxin crystals toxic to dipteran insects such as
mosquitoes and blackflies. Numerous chemical insecticides have been used to control some insects. While
chemical insecticides have knock down effect, they are too expensive in the developing countries and harmful
to both humans and the environment. In addition, target insect pests develop biological resistance rapidly
especially at higher rates of application. Thus, the increase in pesticidal application to control this pest has
urged to researcher to search for biological control alternatives that would be a good component of Integrated
Pest Management. To clone and analyze B. thuringiensis gene fragments isolated by restriction digest PCR.
Specific primers were designated to amplify the genes of B. thuringiensis serovar entomocidus INA 288, and
the PCR products were classified and re-amplyfied by PCR to obtained the fragments for subsequent
purification and cloning into the pGEM-T vectors, followed by rapid identification. The recombinant plasmid
were extracted from positive clones and the target gene fragments were sequenced. The sequence analysis
showed that cry4Aa had similarity with cryINA 288. It seems a novel mosquitocidal cry gene. It may be
concluded that dipteracidal polypeptide of entomocidus INA 288 (cryINA 288) consisted of 703 amino acids
with conserved blocks and amino acid sequence was aligned to that of cry4Aa. Furthemore, an aligment of the
conserved block sequences among the cry INA 288 and other mosquitocidal proteins was performed.

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
