Durabilidade de estruturas de concreto armado em ambiente marinho: estudo de caso
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Curso de Pós-Graduação em Engenharia CivilNeste trabalho estuda-se os efeitos do meio ambiente marinho sobre os elementos estruturais de uma ponte rodoviária em concreto armado. O estudo priorizou a avaliação da deterioração estrutural decorrente de corrosão das armaduras, provocada pelo ataque de íons cloreto impregnados a partir do meio ambiente de exposição. A determinação da concentração de íons cloreto solúveis em água, em diversos pontos de superfícies laterais de um apoio localizado dentro do mar, revelou a ocorrência de valores variáveis com a profundidade do concreto, com a distância em relação ao nível de água e a orientação destas superfícies, caracterizando diferentes zonas de exposição e riscos de corrosão das armaduras. Os resultados são ponderados para a avaliação de intervenções na obra e referências para futuros projetos
Eugenio Battisti e o Antirrenascimento
No full textEsta comunicação concentra-se na obra L’Antirinascimento de Eugenio Battisti e especificamente na compreensão do termo que intitula o livro: as manifestações antirrenascentistas no seio da tradição clássica italiana, principalmente entre os séculos XV e XVI. Pretende-se analisar aquilo que André Chastel aponta no prefácio como a epistemologia do negativo representado pelas produções fantásticas, profanas, ditas anticlássicas em uma tradição tão arraigada pelas métricas da perspectiva e harmonias formais.
This communication is about the L’Antirinascimento, written by Eugenio Battisti, and specifically about the comprehension of its title: the antirenaissance manifestations on the Italian classical tradition, specially during the XV and XVI centuries. Intending to analyze what Andre Chastel called on the preface as the epistemology of the negative, represented by the fantastic productions, profane, called anticlassical on a tradition extremely connected by the metrics of perspective and formal harmonies
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

"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.

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
