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
Phenotypical and transcriptomic analysis of Rfo-Sa1 resistant eggplant interaction with two fungal pathogens
No full textkoamabayili/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
Pepper and Eggplant Genetic Resources
No full textPeppers (Capsicum spp.) and eggplants (Solanum spp.) are vegetable crops from the Solanaceae family that have spread worldwide and are important as a source of health-related compounds for humans. Several pepper and eggplant species have been domesticated, and a large number of wild relatives exist for both crops. Over 25,000 domesticated and wild accessions are stored in the major germplasm banks, representing the readily available genepool for genetic improvement of the cultivated forms. In the present chapter, we revisit the origin, domestication, and spread of peppers and eggplants, describing the main botanical characteristics, agronomic and qualitative properties, and providing novel insight into the recent classification and phylogenetic relationships. Potentiality and constraints of the use of genetic resources in intraspecific and interspecific hybridization, description of breeding programs carried out in the past years for agronomic traits, improvement of biotic (fungal, bacterial, nematodes, and viruses) and abiotic stresses (heat, drought, and salinity), tolerance, and genetic studies for the identification of genes underlying traits of interest, are widely discussed.Fil: Toppino, Laura.

SNP mapping and identification of QTL for horticultural key breeding traits in eggplant (Solanum melongena L.)
No full textEggplant genome is relatively unexplored, especially compared to those of the
other major Solanaceae crops tomato, pepper and potato. We recently combined the
developed Restriction-site Associated DNA (RAD) approach with Illumina DNA
sequencing to effect the rapid and mass discovery of both SNP and SSR markers in
eggplant for mapping as well as QTL analysis. A subset of 384 SNPs was used to
genotype an F2 intraspecific mapping population and integrated into a previously
developed genetic linkage map encompassing a total of 415 markers. The framework
map includes 12 linkage groups spanning 1,390 cM with an average map distance of
3.8 cM. The newly developed map was used for identifying quantitative trait loci (QTL)
for the traits fruit weight, maximum fruit diameter, fruit shape (length max/diameter
max) and adaxial leaf lamina anthocyanin in two locations. On the whole 18 and 17
QTLs were identified in both environments, and at least one major QTL for each trait
was identified on the basis of both LOD threshold and coefficient of determination
(R2) values
