Segregación de polimorfismos en μ-calpaina y calpastatina en ganado para carne en Puerto Rico
Full text linkThe distribution of single nucleotide polymorphisms (SNP) in two regions of Calpain (CAPN1-316 and CAPN1-4751) and a SNP in Calpastatin (CAST) was determined in beef cattle raised in Puerto Rico (n=271). Genotypic and allelic frequencies were determined for each SNP in Senepol (n=53), Charolais (n=49), Angus (n=27), Charbray (n=38), Brahman (n=16), Zebu (n=16) and crossbred bulls (n=72). For CAPN1-ZAB, the global genotypic frequencies (n=219) were 0.07/CC (n=15), 0.38/CG (n=83) and 0.55/GG (n=121) with allelic frequencies of 0.21/C and 0.74/G. The CC genotype was absent in Charbray, Charoláis, Angus, Zebu and Brahman bulls. In Charolais, Zebu, Brahman and Charbray the GG genotype was in greater proportion than CG, while the inverse was observed in the Senepol breed. In Angus and crossbred animals, the CG and GG genotype were found in equal distribution. The global genotypic frequencies for CAPN1-4751 (n=256) were 0.17/CC (n=44), 0.45/CT (n=114) and 0.38/TT (n=98). The allelic frequencies were 0.39/C and 0.61/T. Animals inheriting the CT genotype were more frequent in Charolais, Senepol, Angus and crossbred bulls, while the TT was more common in Charbray and Brahman. For CAST, the global genotypic frequencies (n=261) were 0.04/CC (n=10), 0.26/CT (n=68), and 0.70/TT (n=183), respectively. The global allelic frequencies were 0.17/C and 0.83/T. The CC genotype was not found in Charoláis, Angus and Brahman breeds. The TT animals were more frequent in all breeds, as well as in the crossbred population. The segregation of polymorphisms in CAPN1 and CAST could potentially be associated with differences in economically important traits for Puerto Rican beef cattle, but this possibility should be evaluated by genotyping a broad range of animals with detailed phenotypic data before incorporating these SNP into markerassisted selection programs.Se determinó la distribución de polimorfismos de nucleótidos simples (SNP, por sus siglas en inglés) en dos regiones de calpaína (CAPN1- 316 y CAPN1-4751) y una en calpastatina (CAST) en ganado para carne criado en Puerto Rico (n=271). Las frecuencias genotípicas y alélicas se determinaron para cada SNP en las razas Senepol (n=53), Charolais (n=49), Angus (n=27), Charbray (n=38), Brahman (n=16), Cebú (n=16) y toros cruzados (n=72). Para CAPN1-316, las frecuencias genotípicas globales (n=219) fueron 0.07/CC (n=15), 0.38/CG (n=83) y 0.55/GG (n=121) con frecuencias alélicas de 0.26/C y 0.74/G. El genotipo CC estuvo ausente en las razas Charbray, Charolais, Angus, Cebú y Brahman. En toros Charolais, Cebú, Brahman y Charbray el genotipo GG fue mayor que el CG mientras lo inverso fue observado en toros Senepol. En animales Angus y en los cruces, los genotipos CG y GG se encontraron equitativamente distribuidos. Las frecuencias genotípicas globales (n=256) para CAPN1-4751 fueron 0.17/CC (n=44), 0.45/CT (n=114) y 0.38/ TT (n=98). Las frecuencias alélicas fueron 0.39/C y 0.61/T. Animales con el genotipo CT fueron más frecuentes en Charolais, Senepol, Angus y cruces. Los animales TT fueron más comunes en razas Charbray y Brahman. Para CAST, las frecuencias genotípicas globales (n=261) fueron 0.04/CC (n=10), 0.26/CT (n=68), y 0.70/TT (n=183), respectivamente, con frecuencias alélicas de 0.17/C y 0.83/T. No se encontraron animales de genotipo CC en Charolais, Angus y Brahman. El genotipo TT estuvo en mayor proporción en todas las razas y en los animales cruzados. La segregación de polimorfismos en CAPN1 y CAST puede estar implicada en diferencias en características de importancia económica en bovinos para carne criados en Puerto Rico, esta posibilidad debe ser evaluada mediante la genotipificación de un número grande de animales con registros de producción, previo a la incorporación de estos marcadores moleculares en programas de selección genética
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
