De invertido a queer: as homossexualidades maculinas em Adolfo Caminha e em Caio Fernando Abreu
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-graduação em Literatura, Florianópolis, 2011Este trabalho apresenta uma análise das formas de representação dos sujeitos orientados homoafetivamente e suas performances, investigando a construção de identidades a partir das narrativas de Caio Fernando Abreu na busca de compreender se, de fato, houve uma substancial mudança nas formas de representar a homossexualidade masculina ao longo do século XX e, se, em relação a obras como Bom-crioulo, a literatura contemporânea pode ser considerada mais permissiva ultrapassando os limites da apropriação do tema a simples metáfora de degeneração em discursos moralistas. Através da articulação da Teoria Queer e dos Estudos Feministas e da Análise do Discurso (Foucault), procura-se, ainda, perceber que identidades, espaços e temporalidades são possíveis ao deslocar ou manter a matriz cultural de inteligibilidade que estabelece uma relação mimética sexo-gênero-prática sexual.This paper presents an analysis of the forms of representation of subjects homoaffectively oriented and their performances, investigating the construction of identities through the narratives of Caio Fernando Abreu with the intention of understanding whether, in fact, there has been (or not) a substantial change in ways of representing male homosexuality throughout the twentieth century and if, in relation to works such as Bom Crioulo, contemporary literature can be considered more permissive beyond the ownership of the boundaries of limited comprehension of the theme to simple metaphor of degeneration into moral discourse. Through the articulation of Queer Theory and Feminist Studies and Discourse Analysis (Foucault), we seek to identify which identities, spaces and temporalities are possible when moving or maintaining the cultural intelligibility that establishes a mimetic relation sex-gender-sexual practice
High-Dimensional Graphical Model Search with the gRapHD R Package
No full textThis paper presents the R package gRapHD for efficient selection of high-dimensional undirected graphical models. The package provides tools for selecting trees, forests, and decomposable models minimizing information criteria such as AIC or BIC, and for displaying the independence graphs of the models. It has also some useful tools for analysing graphical structures. It supports the use of discrete, continuous, or both types of variables.
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Velocidades de germinação de sementes e o vigor de mudas do híbrido interespecífico caiaué x dendê.
No full textConsiderando a hipótese de que as sementes de germinação tardia tendem a produzir plantas mais fracas, o objetivo do trabalho foi avaliar a influência da velocidade de germinação sobre o vigor de mudas do híbrido interespecífico (HIE) BRS Manicoré.No certificado do pôster aparecem 07 autores na seguinte ordem: LOBATO, R.

Search for long-lived stopped R-hadrons decaying out of time with pp collisions using the ATLAS detector
No full textAn updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb−1 of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. Selections based on jet shape and muon system activity are applied to discriminate signal events from cosmic ray and beam-halo muon backgrounds. In the absence of an excess of events, improved limits are set on gluino, stop, and sbottom masses for different decays, lifetimes, and neutralino masses. With a neutralino of mass 100 GeV, the analysis excludes gluinos with mass below 832 GeV (with an expected lower limit of 731 GeV), for a gluino lifetime between 10 μs and 1000 s in the generic R-hadron model with equal branching ratios for decays to qq¯χ˜0 and gχ˜0. Under the same assumptions for the neutralino mass and squark lifetime, top squarks and bottom squarks in the Regge R-hadron model are excluded with masses below 379 and 344 GeV, respectively
Corrigendum to "Graphs and digraphs with all 2--factors isomorphic" [J. of Comb. Th. Ser. B 92, (2) (2004) 395--404]
No full textWe point out several errors in our article [M. Abreu, R.E.L. Aldred, M. Funk, B. Jackson, D. Labbate, J. Sheehan, Graphs and digraphs with all 2-factor isomorphic, J. Combin. Theory Ser. B 92 (2004) 395–404] which were caused by our misquoting of a theorem of C. Thomassen. We also describe how the correct statement of Thomassen’s theorem, together with another of his theorems, can be used to obtain weaker results than those incorrectly stated in our original article
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
