ABSTRACT

The present study analyzed the profile of dental researchers receiving grants related to their productivity in research from the Brazilian National Research and Development Council (CNPq). Data collection was carried out in March 2008, using the Brazilian database for curriculum vitae (Lattes Format). There were 144 researchers registered in the database and linked to 25 institutions. These researchers published a total of 12,997 full-text articles, 6,927 of which were published in the last 5 years. Category 1 grant holders (n=77) were responsible for 53.5% of this production; Category 2 grant holders (n=65) were responsible for 45.1%; Senior grant holders (n=2) were responsible for 1.4%. Regarding institutional affiliation, 90.3% of the research grants holders develop activities at public institutions and 9.7% develop activities in private institutions. Furthermore, 84.0% of the researchers are linked to institutions located in the southeast region of Brazil and 75.0% of the researchers perform their activities in the state of São Paulo. This study performed a mapping of the distribution of CNPq researchers, revealing a concentration in the southeast region of the country, especially in the state of São Paulo. The findings of the present study also demonstrate the important contribution of grant holders to the scientific production in dentistry in Brazil.

Key Words: research, research personnel, research support, dental research, bibliometrics.

INTRODUCTION

Changes in the organization of the historic western model of the State have been observed, with a clear tendency toward a reduction in direct economic and social activities. There has also been a broadening in some of the roles of the State with regard to designing policies and regulations that address diverse parameters of social life. As a result, it is well accepted that scientific knowledge is essential to the foundation of the decision-making process (1).

Knowledge is also used to organize healthcare activities. Contemporary society recognizes that science, technology and innovation are differentiating factors in the social and economic development of countries and regions. Thus, science and technology in the healthcare field are the objects of different governmental and academic initiatives (2).

In Brazil, as well as in other Latin American countries, there was a considerable increase in investments in science in the 1970s and 1980s (3). Moreover, scientometric studies have recorded a significant growth in Brazilian scientific production in recent decades. The establishment of postgraduate courses in the second half of the 1960s marked the beginning of the formation of a vigorous scientific community in the country. In the last 15 years, Brazil has seen an expressive increase in scientific production, as measured by the number of scientific articles published in international dental journals. Brazilian production currently indexed in the Web of Science database approaches 1.5% of the world's scientific production. This participation was 0.5% two decades ago (4,5).

Considering the scientific performance exhibited in the last 40 years of more expressive activities in Science and Technology in Brazil, greater production efforts have been observed in fields that are more qualified in human resources, namely, physics, medicine (and its sub-fields, including dentistry), biomedical sciences (biochemistry, biophysics, microbiology, pharmacology, neuroscience, cell biology, developmental biology, physiology and immunology) and chemistry. Together, these fields account for 70% of national scientific production (6). According to Cury (7), based on the ISI Web of Science, listing address, article, ‘Dent*', ‘Brazil*', the number of papers published between 2001 and 2003 (n = 898) was similar to that of the entire past century (n = 854). The asterisk (*) means that the search was made from the root of the word.

The Brazilian National Research and Development Council (CNPq) is an agency linked to the Ministry of Science and Technology. Investments from this agency are directed toward the formation and absorption of human resources. The aim is to finance research projects that contribute to the production of scientific knowledge and the generation of new opportunities of growth for the country (8). The ‘Productivity in Research' grant is an ‘Individual grant' modality whose purpose is to distinguish outstanding Brazilian researchers, valuing their scientific production according to the criteria established by the CNPq and its Advisory Committees. Therefore, this grant represents a constant stimulus to Brazilian researchers (9).

The increase in Brazilian dental scientific production is demonstrated by the growing number of articles by researchers affiliated to Brazilian universities that are published in both national and international journals in order to make public scientific findings and disseminate knowledge in the field of Dentistry (10).

The aim of the present study was to determine the profile and distribution of researchers in Dentistry who receive productivity CNPq grants.

 

MATERIAL AND METHODS

A list of dental researchers with active productivity grants was obtained from the CNPq website (www.cnpq.br) in March 2008, following the criteria established by the CNPq Directive Body. Research grant holders in the field of Dentistry are selected based on their scientific productivity over the last 5 years.

The curricula vitae of all researchers for each of the categories and sublevels (2, 1D, 1C, 1B, 1A, SR) were analyzed. The classification of researchers is based on criteria such as technical-scientific production, participation in the formation of human resources and specific performance in each field of the science. The analysis of curricula vitae was carried out using the Lattes Format (available at www.cnpq.br), which consists of a database of curricula vitae and institutions of science and technology, developed for CNPq and used as a curriculum vitae information system by the Ministry of Science and Technology (MCT), the Financing Body for Studies and Projects (FINEP), the Coordination of Higher Education Personnel Improvement (CAPES) as well as all institutional agents and the Brazilian scientific community.

Databases containing information of gender, institutional affiliation of the research grant holders and scientific production were constructed. Scientific production was based on the production of full articles in national and international scientific journals referring to the entire period of the researcher's academic activity. Data were analyzed using the Statistical Package for the Social Sciences (SPSS; version 15.0; SPSS Inc. Chicago, IL, USA) and Microsoft Excel software.

 

RESULTS

There were a total of 144 researchers in Dentistry with CNPq productivity grants. The group of researchers was formed by 93 men (64.6%) and 51 women (35.4%), revealing the predominance of the male gender. Furthermore, men were concentrated in Category 1 (58.0%) and women were concentrated in Category 2 (52.9%) (Table 1).

 

 

The analysis of scientific production revealed that 12,997 full-text articles were published in national and international journals, 6,927 of which were published in the last 5 years. Category 1 grant holders were responsible for 53.5% of this production, whereas Category 2 grant holders were responsible for 45.1% and senior grant holders were responsible for 1.4%.

Significant differences in the average number of full-text articles published per researcher in each category and sublevel were observed (Table 2).

 

 

Considering the institutional affiliation, the research grant holders pertained to 25 institutions. A total of 130 (90.3%) developed their activities at public institutions, whereas 14 (9.7%) developed their activities at private institutions. It was also observed that 121 (84.0%) researchers were affiliated with institutions located in the southeast region of Brazil and 108 (75.0%) of all researchers developed their activities in the state of São Paulo (Table 3).

 

 

DISCUSSION

The performance of Brazilian science is related to the formation of human resources in Science and Technology, centered on the recognized success of postgraduate courses that began in the late 1960s. Despite the relatively young age of the Brazilian educational and scientific system, scientific production has grown considerably in all fields of knowledge in recent decades. There has also been an increase in the number of citations of Brazilian studies indexed in international databases (ISI Web of Science) (6,11).

An analysis of the scientific production in the field of Dentistry reveals a significant contribution by researchers with CNPq productivity grants with regard to the publication of scientific articles. There are differences between the research categories and sublevels. The average number of full-text articles published in scientific journals varies according to the category. The groups of researchers in Category 2 produced 38.0% of the full-text articles, whereas the production of Category 1 researchers was 60.8%.

This suggests that production in each of the categories and sublevels is influenced by the average time in the profession and dedication to scientific research, which is lower among Category 2 researchers. This category is known to be less competitive, as classification is determined considering the number of published articles and the qualification of the journals in which they are published. Therefore, the chances are greater for a young researcher to be placed in this research grant group (12).

It is interesting to note the presence of both genders in research activities, with a predominance of the male gender. Women are concentrated among Category 2 researchers, which suggests their more recent entrance into the scientific granting process.

There is a growing awareness that decisions regarding governmental policies and actions should be grounded on scientific evidence, given their complexity and multiple implications. Consequently, there has been an increasing participation of the government as a promoter, financer and executer of scientific/technological development policies and activities (1). This situation began at the end of the last century, thanks to the action of the CNPq and CAPES researchers (7). In this context, most research grant holders in the field of Dentistry develop their activities at public institutions. A previous study found that 77% of researchers in collective healthcare develop their activities at public institutions. This stresses the important role the government plays as an articulator and stimulator of scientific research (12).

For decades, there have been disparities in the development between the large Brazilian macro-regions, which are also expressed in the regional distribution of scientific and technological resources as well as in the regional formation of human resources and knowledge production. The technical-scientific base in Brazil is much more pronounced in the southeast and south regions, to which most of the government investments in science and technology are directed. Indicators reveal that the southeast region houses a large portion of the university centers with a level of excellence in innumerous fields of knowledge as well as the most well-equipped research institutes in the country (13).

The present study demonstrates the concentration of researchers in the southeast region, especially in the state of São Paulo. Acknowledgement should be given to the scientific community of this state and to the São Paulo State Research Foundation (FAPESP), which have undertaken important initiatives in broadening the visibility of Brazilian scientific production.

Regarding the field of Dentistry, 65 (72%) of the 90 postgraduate programs and courses in the country are located in the southeast region (52 in the state of São Paulo), whereas 10 (11%) are located in the southern region, 13 (15%) are located in the northeast region, 1 (1%) is located in the northern region and 1 (1%) is located in the middle-west region (8). This fact shows that the formation of researchers and knowledge production on a regional scale follows the same pattern of disparity as seen in the development of the country. Technical-scientific activities are distributed in a heterogeneous fashion throughout the physical space, accompanying the accumulation of capital (13). However, this phenomenon of research concentration is not exclusively Brazilian in nature. In the United States, about 36% of the scientific production indexed on the databases of the ISI Web of Science in 1998 originated from 4 American states: California, New York, New Jersey and Massachusetts (14).

The present study has limitations regarding the information gathered. The first refers to the quality of information available on the Lattes curricula vitae of the researchers. As the Lattes curriculum vitae is one of the elements employed in judging applications for productivity grants, it is considered an adequate source for the analysis of researcher profiles.

Since the establishement of excellence parameters and information regarding the quality in science currently made available on the internet to the scientific community, an effort has been made by Brazilian professionals to attain certain goals and this is reflected in the growth and improvement of the Brazilian scientific production (7).

Another issue regarding the possibility of overestimating the totality of scientific production is the form of analysis. Articles often have more than one author and two or more authors may be grant holders. In such cases, however, the researchers are frequently classified in different categories and sublevels, which would tend to attenuate the double or triple count of grant holders within a category and sublevel.

The present study addressed the profile and distribution of researchers in the field of Dentistry who receive CNPq productivity grants and emphasized the imbalance of the technical-scientific production among the regions in Brazil. It is the government responsibility to establish policies with the aim of improving its instruments and actions in an effort to diminish the current inequality. The commitment to combating inequality and increasing the standards of balance, especially in the healthcare field, should be the basic premise of the National Science, Technology and Information Policy of the country.
