Abstract
Summary Science in Latin America has experienced vigorous growth in the past decade, as demonstrated by the fact that the Latin American share of the world’s scientific publications increased from 1.8% in 1991 – 1995 to 3.4% in 1999 – 2003. Significant growth has also taken place in the numbers of PhDs in science and engineering (S&E) awarded in Latin American countries in recent years, including those in the natural sciences. Importantly, albeit at different rates, growth has been verified in almost all countries in the region, indicating a general effort to promote the development of S&E. In most research fields, however, the recognition or relative impact of Latin American science, as measured by the average number of citations received by published articles (CpP), is still below world averages and much lower than in developed nations. We show that average CpP values for a set of 34 representative developing and developed countries correlate significantly with gross expenditure in research and development (GERD), with gross domestic product (GDP) per capita and with the number of researchers per million inhabitants (RpM). Among those countries, Latin American nations present some of the lowest average values of CpP (56), GERD (� 1% of GDP) and RpM (52,000). We also examined recent trends in scientific activity in Latin America, with focus on the natural sciences and on biochemistry and molecular biology (BMB). In terms of citation scores, publications in BMB compare favorably to those in other research fields within Latin America. At the same time, however, Latin American BMB is one of the areas for which relative impact – compared to developed nations or normalized to world averages – is lowest. These observations clearly indicate the need to establish effective policies to increase competitiveness in terms of the quality and international recognition of Latin American natural sciences in general, and BMB in particular, as opposed to merely increasing the absolute numbers of publications or the numbers of PhDs awarded in the region.

Abstract Although the number of science and engineering (SE all with 8 to 30 years of scientific production), one from Latin America and another from developed countries. For additional comparison, we included also a group of twelve highly cited and recognized CBP researchers. We used Hirsch's indexes ( h and m ) as main indicators of performance, but compared also classical bibliometric indexes such as total number of citations, total number of papers and the ratio of citation per paper ( CpP )...

Abstract Latin American researchers in science and engineering (S&E), including those in biology and biomedical sciences, are frequently exposed to unstable conditions of financial support, material and human resources, and a limited number of positions at public and private institutions. Such uncertainties impose continuous challenges for the scientific community which, in the best of cases, responds with careful planning and creativity, and in the worst scenario endures the migration of scient...

The number h of papers with at least h citations has been proposed to evaluate individuals scientific research production. This index is robust in several ways but yet strongly dependent on the research field. We propose a complementary index ) ( 2 T a I N h h = , with ) (T a N being the total number of authors in the considered h papers. A researcher with index hI has hI papers with at least hI citation if he/she had published alone. We have obtained the rank plots of h and h I for four Brazili...

In the present paper, the evolution of publication activity and citation impact in Brazil is studied for the period 1991-2003. Besides the analysis of trends in publication and citation patterns and of national publication profiles, an attempt is made to find statistical evidences of the relation between international co-authorship and both research profile and citation impact in the Latin American region. Despite similarities and strong co-publication links with the other countries in the regio...

Abstract Latin America has experienced a vigorous growth in scientific production since the 1990s, rising from 1.7% of the world’s share of science publications in 1990 to 3.2% in 2000. This appears to be a consequence of increasing investment in tertiary education, especially at the doctoral level. However, such growth is not homogeneous among the nations of Latin America, being affected by many issues, such as economical power and expenses in science and technology. Biology - including compara...

A piece of material (part) having a preformed cross-sectional configuration is moved through a pair of pinch rolls located in between right and left hand forming rolls. Each forming roll is position adjustable both laterally and separationwise with respect to the pinch rolls along two longitudinal axes. In addition, each forming roll is rotationally adjustable along two rotational axes. As the part moves through the machine, the right and left hand forming rolls are positioned in accordance with...

ANALISAMOS a pos-graduacao brasileira no que diz respeito a sua diversidade institucional e a sua qualidade. Esta diversidade cresceu nas ultimas decadas. O Brasil tinha, em 2003, um total de 45 instituicoes de pesquisa e doutorado e 73 de mestrado, (alem de 1.554 instituicoes de ensino de graduacao). A distribuicao geografica das instituicoes envolvidas com pos-graduacao e bastante irregular. A relacao entre o numero de instituicoes envolvidas na pos-graduacao no Brasil e nos EUA mantem a mesma...

Kofi Annan, the Secretary-General of the United Nations, recently called attention to the clear inequalities in science between developing and developed countries and to the challenges of building bridges across these gaps that should bring the United Nations and the world scientific community closer to each other (Annan 2003). Mr. Annan stressed the importance of reducing the inequalities in science between developed and developing countries, asserting that “This unbalanced distribution of scie...

There is a worldwide trend towards growth in scientific production in different disciplines. Notable progress of individual countries in Latin America in scientific development is recognised worldwide. However, it is necessary to understand how this scientific knowledge is generated and what are the underlying factors shaping the understanding of local natural resources. Scientific knowledge related to natural resources is a crucial issue for a region that contains the highest proportion of the ...

Scholarly publishing is pivotal for the advancement of science, innovation and national development. In particular, scholarly journals are key to (i) the exploration of scientific and technological frontiers of human knowledge (ii) the dissemination of new scientific and technological knowledge, and (ii) the development and evaluation of qualified human resources. However, for developing countries to continue and improve their institutional capacities for scientific development, they need to hav...

The recent trend of rapid growth in the scientific and engineering activities in East Asian Newly Industrializing Economies (NIEs) resulted in a change in the structure of world knowledge production. In South Korea, particularly, not only the numbers of publications have increased, but there is a noticeable change in the composition of scientific and engineering activities. This paper notes the most of the research on the knowledge production of advanced countries, along with a handful of studie...
