Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Frequencies Of The -330 (t → G) Il-2 And -590 (t → C) Il-4 Gene Polymorphisms In A Population From South-eastern Brazil
No full textPolymorphisms in the promoter regions of cytokine genes may affect their transcription. A T/G substitution at position?330 of the interleukin-2 (IL-2) gene and a T/C substitution at position -590 of the interleukin-4 (IL-4) gene have been described previously. The -590 (T → C) IL-4 gene polymorphism was associated with asthma and atopy in US and Japanese populations. Population genetics is a useful tool for determination of the biological significance of genetic polymorphisms. The aim of this study was to investigate the frequencies of polymorphisms in the promoter regions of the IL-2 and IL-4 genes in a population from south-eastern Brazil and to compare them with those published for other populations. Allele frequencies were estimated in 114 unrelated individuals from São Paulo State. These subjects had an average age of 41.2 years (± 12.4 years) and the ethnic composition of the sample was: 78.07% Caucasian, 11.4% Black and 10.53% Mulatto. DNA from subjects was extracted from epithelial buccal cells, and the PCR-RFLP technique was employed to investigate the -330 (T → G) IL-2 and -590 (T → C) IL-4 gene polymorphisms. The allele frequency of the IL-2 gene polymorphism obtained in our study was similar to that found in UK Caucasoid groups. The T allele frequency of the IL-4 gene polymorphism observed in the Caucasian Brazilian group was similar to that found in UK and Australian populations, while the frequency observed for the Black Brazilian group was similar to that found in Japanese and Kuwaiti Arab populations. The results for the -330 (T → G) IL-2 and -590 (T → C) IL-4 polymorphisms are consistent with the high contribution of European lineages to the population in south-eastern Brazil.294293296Alves-Silva, J., Da Silva Santos, M., Guimaraes, P.E.M., Ferreira, A.C.S., Bandelt, H.-J., Pena, S.D.J., Prado, V.P., The ancestry of Brazilian mtDNA lineages (2000) American Journal of Human Genetics, 67, p. 444Arpini-Sampaio, Z., Costa, M.C.B., Melo, A.A., Carvalho, M.F.V.A., Deus, M.S.M., Simões, A.L., Genetic polymorphisms and ethnic admixture in African-derived Black communities of Notheastern Brazil (1999) Human Biology, 71, p. 69Callegari-Jacques, S.M., Salzano, F.M., Brazilian Indian/non-Indian interactions and their effects (1999) Ciência e Cultura, 51, p. 166Carvalho-Silva, D.R., Santos, F.R., Rocha, J., Pena, S.D., The phylogeography of Brazilian Y-chromosome lineages (2001) American Journal of Human Genetics, 68, p. 281Chen, Y.S., Torroni, A., Excoffier, L., Santachiara-Benerecetti, A.S., Wallace, D.C., Analysis of mtDNA variation in African populations reveals the most ancient of all human continent-specific haplogroups (1995) American Journal of Human Genetics, 57, p. 133Constans, J., DNA and protein polymorphism: Application to anthropology and human genetics (1988) Anthropologischer Anzeiger, 46, p. 97Faucz, F.R., Probst, C.M., Petzl-Erler, M.L., Polymorphism of LMP2 and TAP1, LMP7 and TAP2 in Brazilian Amerindians and Caucasoids: Implications for the evolution of allelic and haplotypic diversity (2000) European Journal of Immunogenetics, 27, p. 5Hijazi, Z., Haider, M.Z., Interleukin-4 gene promoter polymorphism [C590T] and asthma in Kuwaiti Arabs (2000) International Archives of Allergy and Immunology, 122, p. 190(2000) Brasil: 500 anos de Povoamento, , IBGE, Rio de JaneiroJohn, S., Turner, D., Donn, R., Sinnot, P., Worthington, J., Ollier, W.E.R., Hutchinson, I.V., Hajeer, A.H., Two novel biallelic polymorphism in the IL-2 gene (1998) European Journal of Immunogenetics, 25, p. 419Kornman, K.S., Crane, A., Wang, H.-Y., Di Giovine, F.S., Newman, M.G., Pirk, F.W., Wilson T.G., Jr., Duff, G.W., The interleukin-1 genotype as a severity factor in adult periodontal disease (1997) Journal of Clinical Periodontology, 24, p. 72Lazarus, M., Hajeer, A.H., Turner, D., Sinnott, P., Worthington, J., Ollier, W.E.R., Hutchinson, I.V., Genetic variation in the interleukin-10 gene promoter and systemic lupus erythematosus (1997) Journal of Rheumatology, 24, p. 2314Noguchi, E., Shibasaki, M., Arinami, T., Takeda, K., Yokouchi, Y., Kawashima, T., Yanagi, H., Hamaguchi, H., Association of asthma and the interleukin-4 promoter gene in Japanese (1998) Clinical and Experimental Allergy, 28, p. 449Probst, C.M., Bompeixe, E.P., Pereira, N.F., De Dalalio, M.M.O., Visentainer, J.E.I., Tsuneto, L.T., Petzl-Erler, M.L., HLA polymorphism and evaluation of European, African and Am erindian contribution to the white and mulatto populations from Paraná, Brazil (2000) Human Biology, 72, p. 597Reynard, M.P., Turner, D., Navarrete, C.V., Allele frequencies of polymorphisms of the tumor necrosis factor-α, interleukin-10, interferon-γ and interleukin-2 genes in a North European Caucasoid group from the UK (2000) European Journal of Immunogenetics, 27, p. 241Rosenwasser, L.J., Klemm, D.J., Dresback, J.K., Promoter polymorphisms in the chromosome 5 gene cluster in asthma and atopy (1995) Clinical and Experimental Allergy, 25 (SUPPL. 2), p. 74Scarel, R.M., Trevilatto, P.C., Di Hipólito O., Jr., Camargo, L.E.A., Line, S.R.P., Absence of mutations in the homeodomain of the MSX1 gene in patients with hypodontia (2000) American Journal of Medical Genetics, 92, p. 346Scarel-Caminaga, R.M., Trevilatto, P.C., Souza, A.P., Brito R.B., Jr., Line, S.R.P., Investigation of an IL-2 polymorphism in patients with different levels of chronic periodontitis (2002) Journal of Clinical Periodontology, , in pressSoares, J.F., Siqueira, A.L., (1999) Introdução á Estatística Médica, , Departamento de Estatística, Universidade Federal de Minas Gerais, Belo Horizonte, BrazilTrevilatto, P.C., Line, S.R.P., Use of buccal epithelial cells for PCR amplification of large DNA fragments (2000) Journal of Forensic Odonto-Stomatology, 31, p. 393Walley, A.J., Cookson, W.O.C.M., Investigation of an interleukin-4 promoter polymorphism for associations with asthma and atopy (1996) Journal of Medical Genetics, 33, p. 689Woolf, B., On estimating the relation between blood groups and disease (1955) Annals of Human Genetics, 19, p. 25
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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.
