ABSTRACT

That English is the lingua franca of today's science is an indisputable fact. Publication in English in international journals is a pre-requisite for a research paper to gain visibility in academia. However, English proficiency appears to be taken for granted in the scientific community, though this language can be a hurdle for a number of authors, particularly from non-native English-speaking countries. The influence of English proficiency on the publication output of Brazilian authors has never been assessed. We report our preliminary data on the relationship between the English proficiency of 51,223 researchers registered in the CNPq database and their publication output in international journals. We have found that publication rates are higher for those authors with good command of English, particularly written English. Although our research is still underway and our results are preliminary, they suggest that the correlation between written English proficiency and research productivity should not be underestimated. We also present the comments of some Brazilian scientists with high publication records on the relevance of communication skills to the scientific enterprise.

ABSTRACT

We analyzed the trends of scientific output of the University Hospital, Federal University of Rio de Janeiro. A total of 1420 publications were classified according to pattern and visibility. Most were non-research publications with domestic visibility. With time, there was a tendency to shift from non-research (or education-oriented) publications with domestic visibility to research publications with international visibility. This change may reflect new academic attitudes within the institution concerning the objectives of the hospital and the establishment of scientific research activities. The emphasis of this University Hospital had been on the training of new physicians. However, more recently, the production of new knowledge has been incorporated as a new objective. The analysis of the scientific production of the most productive sectors of the hospital also showed that most are developing non-research studies devoted to the local public while a few of the sectors are carrying out research studies published in journals with international status. The dilemma of quality versus quantity and of education versus research-oriented publication seems, however, to continue to exist within the specialized sectors. The methodology described here to analyze the scientific production of a university hospital can be used as a tool to better understand the evolution of medical research in Brazil and also to help formulate public policies and new strategies to include research among the major objectives of University Hospitals.

ABSTRACT

The technological evolution of mankind accelerated enormously after the institutionalization of science in the 19th century. In parallel with the vast number of beneficial effects derived from the scientific revolution, the explosion of new knowledge and its centralization in only a few countries has generated a number of complex situations that present major challenges for the modern science. These include the asymmetrical distribution in the planet of young people and science, the super-specialization derived from the information overload and the difficulties in teaching the vast amount of new knowledge generated each year by science.

ABSTRACT

Vanadate rapidly promotes the cleavage of phosphoenolpyruvate with phosphate liberation. This was not observed when ATP, glucose-6-phosphate and acetyl phosphate were incubated with vanadate. 51V NMR spectra shows that phosphoenolpyruvate and acetyl phosphate broadened and shifted upfield the monomeric vanadate signal at -561 ppm, indicative of vanadate/phosphate interactions. Comparatively, smaller changes were detected when glucose-6-phosphate was added to the vanadate solution. The shift behavior was not observed in the presence of ATP, ADP or pyruvate.
