Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Measurement of the CKM angle gamma from a combination of B->Dh analyses
No full textA combination of three LHCb measurements of the CKM angle gamma is presented. The decays B->DK and B->Dpi are used, where D denotes an admixture of D0 and D0-bar mesons, decaying into K+K-, pi+pi-, K+-pi-+, K+-pi-+pi+-pi-+, KSpi+pi-, or KSK+K- final states. All measurements use a dataset corresponding to 1.0 fb-1 of integrated luminosity. Combining results from B->DK decays alone a best-fit value of gamma = 72.0 deg is found, and confidence intervals are set gamma in [56.4,86.7] deg at 68% CL, gamma in [42.6,99.6] deg at 95% CL. The best-fit value of gamma found from a combination of results from B->Dpi decays alone, is gamma = 18.9 deg, and the confidence intervals gamma in [7.4,99.2] deg or [167.9,176.4] deg at 68% CL, are set, without constraint at 95% CL. The combination of results from B->DK and B->Dpi decays gives a best-fit value of gamma = 72.6 deg and the confidence intervals gamma in [55.4,82.3] deg at 68% CL, gamma in [40.2,92.7] deg at 95% CL are set. All values are expressed modulo 180 deg, and are obtained taking into account the effect of D0-D0bar mixing
Inquiry into the interlocution of students engaged with mathematics: appreciating links between research and practice
No full textFor either to be useful, links between research and practice are critical. Just as important are connections between the practice of students engaged in mathematical activity and research that seeks to understand that practice. This research report explores lessons that researchers and practitioners can learn from an inquiry into the interlocution of students working collaboratively in small groups when engaged in talking and listening to each other. We use the term interlocution to denote discursive practices of learners in conversational exchanges. Questions that motivate this research included the following. What discursive practices do interlocutors employ as they work collaboratively to understand and resolve mathematical tasks? How do these practices influence the growth of their mathematical ideas? In what ways do their discursive practices help them move from a contextualized, situated task to generalize the task or their solution? Do students' discursive practices assist them to connect and generalize ideas from a new problem to others on which they have worked?Powell, A. B., & Maher, C. A. (2002).

Engraçadinha : passagens e cortes / Nelson Rodrigues na televisão
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoAsfalto Selvagem I e II - Engraçadinha seus amores e seus pecados foi escrito por Nelson Rodrigues, originalmente, sob a forma de folhetim, diariamente publicado no jornal Ultima Hora (1959-60), e seguindo o caminho de seus folhetins anteriores recebeu uma impressão posterior (1961) em forma de livro, "transformando-se" em romance. Em 1995, novamente, Asfalto Selvagem... migra para outro veículo da indústria cultural indo parar num seriado de televisão. Este trabalho propõe retraçar as pontes entre o folhetim como forma de literatura industrializada e a televisão como veículo da indústria cultural e como bem simbólico (na cultura brasileira), a fim de localizar Asfalto Selvagem: Engraçadinha seus amores e seus pecados em sua passagem do jornal à televisão em alguns aspectos implicados nesse processo. Em primeiro lugar, na obra de Nelson Rodrigues, Engraçadinha destaca-se em sua travessia social de gêneros e como romance-folhetim. Em segundo lugar, há uma re-montagem histórica da teledramaturgia como pano de fundo propiciador de uma exposição do folhetim de Nelson Rodrigues. Em terceiro lugar, a passagem, propriamente dita, do folhetim à imagem, se por um lado reforça o caráter conservador da TV, por outro, atualiza a transgressividade erótica presente no texto rodrigueano, já como uma adaptação ao século XX do folhetim do século XIX
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Sempre este homem fatal: Otto Lara Resende, personagem de Nelson Rodrigues/ Always Writing About this Fatal Man: Otto Lara Resende, a Nelson Rodrigues’s Character
No full textResumo: Nelson Rodrigues é conhecido por ser um escritor obsessivo, reiterando muitas vezes certos temas, certos procedimentos, certos personagens. Uma de suas maiores obsessões foi seu amigo Otto Lara Resende, inúmeras vezes retratado em seus trabalhos. Este artigo analisa como o escritor mineiro é apresentado nas obras de Nelson, que estratégias são utilizadas para isso e a que serve tratar constantemente da personalidade de Otto em textos nos quais ele surge meio abruptamente em meio a outros personagens, interagindo com eles com a máxima naturalidade, ou em que é citado como protagonista de histórias exemplares ou emissor de frases marcadas por extraordinário brilhantismo verbal.Palavras-chave: Nelson Rodrigues; Otto Lara Resende; obsessão; ficção e realidade.Abstract: Nelson Rodrigues is well-known for being an obsessive writer, often reiterating subjects, procedures, and characters. One of his strongest and most recurring obsessions was his friend Otto Lara Resende, a writer and journalist who was portrayed many times in his works. This article analyzes how Rodrigues shows Resende in his writings, the strategies used in order to do that and what purpose he has in mind when he constantly explores aspects of Resende’s personality in the midst of other characters, naturallyinteracting with them, or when Rodrigues tells stories in which Resende is the protagonist or he is the author of phrases that are expression of an extraordinary verbal talent.Keywords: Nelson Rodrigues; Otto Lara Resende; obsession; fiction and reality.Resumo: Nelson Rodrigues é conhecido por ser um escritor obsessivo, reiterando muitas vezes certos temas, certos procedimentos, certos personagens.
