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.
BRS Ajubá, nova cultivar de abacaxi.
No full textA fusariose é a doença mais importante da cultura do abacaxi no Brasil, onde teve seu primeiro relato em 1964, provocando podridão em frutos da cultivar Smooth Cayenne. Atualmente, a fusariose está presente nas principais regiões produtoras do País, causando elevadas perdas na produção de fruto. O seu controle, fundamenta-se na integração de várias medidas, incluindo práticas de controle cultural, químico e genético mediante o cultivo de cultivares resistentes (Matos et al., 2001)
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
Effect of glutathione synthesis stimulation during in vitro maturation of ovine oocytes on embryo development and intracellular peroxide content
No full textCysteamine and beta-mercaptoethanol supplementation of in vitro maturation (IVM) medium has been found to increase intracellular glutathione (GSH) content in oocytes and to improve embryo development and quality in several species. The objective of this experiment was to study the effect of cysteamine and beta-mercaptoethanol added during IVM of sheep oocytes on GSH synthesis and embryo development. Furthermore, we examined if cysteamine addition (hence GSH production) had an effect on the reduction of the intracellular peroxide content. We matured oocytes obtained from ovaries collected at a slaughterhouse in vitro in the presence of 0, 50, 100, and 200 microM cysteamine (Experiment 1) or with 0, 50, 100, and 200 microM beta-mercaptoethanol (Experiment 2). Following fertilization and embryo development, there was a increasing level of morula and blastocyst development in the presence of cysteamine, reaching significance in the presence of 200 microM (P < 0.05). However, beta-mercaptoethanol did not influence on the rate of embryo development. GSH levels were measured in oocytes matured in the presence or absence of 200 microM cysteamine (Experiment 3) or 50 microM beta-mercaptoethanol (Experiment 4), with or without buthionine sulfoximide (BSO), an inhibitor of GSH synthesis. Results demonstrated that for both cysteamine and beta-mercaptoethanol, intracellular GSH levels increased against control values (P < 0.01), which was abolished in the presence of BSO. Finally, we reduced intracellular peroxide levels, as measured by the relative fluorescence of the intracellular peroxide probe, carboxy-H2DCFDA, in the presence of either 200 microM cysteamine or 50 microM beta-mercaptoethanol (Experiment 5). These results demonstrate that cysteamine, but not beta-mercaptoethanol, when present during IVM, stimulates sheep embryo development; both cysteamine and beta-mercaptoethanol stimulate GSH synthesis; the increase in intracellular GSH is associated with a decrease in peroxide levels within oocytes.Daniel G. de Matos, Bianca Gasparrini, Sergio R.

Atypical patterns of response and progression in the era of immunotherapy combinations
No full textIn the immunoncology era, an acceleration of tumor growth upon immune checkpoint inhibitors (ICI), defined as hyperprogressive disease (HPD) has been observed across different cancers. Although in non-small-cell lung cancer, most of the available evidence regarding HPD has been reported for patients treated with single agent PD-1 and PD-L1 inhibitors, in retrospective series a variable proportion of patients receiving ICI combinations also experienced HPD. Similarly, the shape of survival curves and the progression rates in clinical trials testing combinations of PD-1/PD-L1 inhibitors and anti-CTLA-4 agents suggest the occurrence of HPD. Few data are available regarding pseudoprogression upon ICI combinations. However, considering that pseudoprogression has been reported for anti-PD-1/PD-L1 agents and for CTLA-4 inhibitors separately, it is likely that it may occur also upon combinations of these two classes of drugs
