Scientific production in Computer Science: A comparative study of Brazil and other countries

In this paper we present a study about scientific production in Computer Science in Brazil and several other countries, as measured by the number of articles in journals and conference proceedings indexed by ISI and by Scopus. We compare the Brazilian production from 2001 to 2005 with some Latin American, Latin European, BRIC (Brazil, Russia, India, China), and other relevant countries (South Korea, Australia and USA). We also classify and compare these countries according to the ratio of publications in journals and conferences (the ones indexed by the two services). The results show that Brazil has by far the largest production among Latin American countries, has a production about one third of Spain’s, one fourth of Italy’s, and about the same as India and Russia. The growth in Brazilian publications during the period places the country in the mid-range group and the distribution of Brazilian production according to impact factor is similar to most countries.     

A two-dimensional approach to evaluate the scientific production of countries (case study: the basic sciences)

The quantity and quality of scientific output of the topmost 50 countries in the four basic sciences (agricultural & biological sciences, chemistry, mathematics, and physics & astronomy) are studied in the period of the recent 12 years (1996–2007). In order to rank the countries, a novel two-dimensional method is proposed, which is inspired by the H-index and other methods based on quality and quantity measures. The countries data are represented in a “quantity–quality diagram”, and partitioned by a conventional statistical algorithm into three clusters, members of which are rather the same in all of the basic sciences. The results offer a new perspective on the global positions of countries with regards to their scientific output.     

A comparative study of patenting activity in U.S. and Brazilian scientific institutions

Patents generated from scientific research indicate academic involvement in technology development. Academic patenting activity is recent, even in developed countries. This study compares patenting activity of Brazilian and American universities. Brazilian universities had 29.5-fold increase in applications and 4.01-fold in grants (1990–2001), about twice the increase presented by American universities in this period. However, a significant fraction of Brazilian academic applications are abandoned due to the lack of specialized staff to help in writing and to shepherd the application through the patenting process in universities. The participation of research institutes in technological innovation is increasing steadily, even without financial incentives. This revised version was published online in June 2006 with corrections to the Cover Date.

Spanish performance in life sciences. A comparative appraisal of the scientific production of Spain and five other European countries in 1989

The output in life science disciplines from Spain and five other European countries has been measured in a datafile derived from theCurrent Contents-Life Sciences on diskette (1989). The results of this flash evaluation were contrasted with data retrieved from a survey covering the yearly output during the 1973–83 period and thee 1981–85 aggregated value from Schubert, Glänzel, Braun datafiles. The results of these studies showed an increasing share of Spain in the six countries' output, especially in the subfields of organic chemistry and phytochemistry. However, the quality of the Spanish articles—as deduced from the journal impact factors (JRC-1989)—is below the six countries average. The usefulness of the Current Contents on diskette for handy and reliable flash evaluations has been ascertained through a comparative analysis with more comprehensive surveys.     

A propensity score approach in the impact evaluation on scientific production in Brazilian biodiversity research: the BIOTA Program

Evaluation has become a regular practice in the management of science, technology and innovation (ST&I) programs. Several methods have been developed to identify the results and impacts of programs of this kind. Most evaluations that adopt such an approach conclude that the interventions concerned, in this case ST&I programs, had a positive impact compared with the baseline, but do not control for any effects that might have improved the indicators even in the absence of intervention, such as improvements in the socio-economic context. The quasi-experimental approach therefore arises as an appropriate way to identify the real contributions of a given intervention. This paper describes and discusses the utilization of propensity score (PS) in quasi-experiments as a methodology to evaluate the impact on scientific production of research programs, presenting a case study of the BIOTA Program run by FAPESP, the State of São Paulo Research Foundation (Brazil). Fundamentals of quasi-experiments and causal inference are presented, stressing the need to control for biases due to lack of randomization, also a brief introduction to the PS estimation and weighting technique used to correct for observed bias. The application of the PS methodology is compared to the traditional multivariate analysis usually employed.

Scientific collaboration in Brazilian researches: a comparative study in the information science,mathematics and dentistry fields

This study attempts to describe, in a comparative way, scientific collaboration and co-authoring activities and understanding of Brazilian researchers of productivity level 1 at the National Counsel of Technological and Scientific Development (CNPq). In order to do so, a questionnaire was sent to the researchers of productivity level 1 at CNPq in the Mathematics, Dentistry and Information Science fields, with questions about scientific collaboration and co-authoring activities. We analyzed the scientific production of the researchers who answered the questionnaire and we have identified that 78% of the participants consider that scientific collaboration and co-authorship are different activities, and the potential and usual number of research collaborators is between 2 and 3 in Mathematics and Information Science, and between 5 and 6 collaborators in Dentistry. Differences among fields were pointed out by identifying main collaborators and co-authors. The reasons for collaborating vary according to the nature of the research, however, the percentages are high in these three areas: “training of researchers and students”, “desire to increase their own experience through the experience of others” and “increased productivity.” From the analysis of the scientific production declared in their Lattes Curriculum, we have found that the average number of authors per publication in the field of Information Science is 2.2 authors, in Mathematics is 2.8 authors per publication, and in Dentistry the average is 5.3 authors per publication. We have concluded that scientific collaboration and co-authorship are terms assigned to different activities for the analyzed fields.     

Assessment of a university's scientific capabilities and profile: The case of the faculty of biological sciences of the Pontificia Universidad Catolica de Chile

The scientific capabilities and performance profiles of the Faculty of Biological Sciences of the Pontificia Universidad Católica de Chile were assessed building performance indicators from the ISI's Chile-National Citation Report, 1981–1992. Consistent with the educational goals of the Faculty, the scientific activity which nurtures graduate training, especially at the doctoral level, was examined field by field and compared to Chilean and World scores. The approach rendered a portrait of the Faculty which depicts, trends, strengths and weaknesses, and standards for the evaluation of future activity. The study shows a very competitive performance in most of the fields, relative to national and world average achievements. A remarkable finding was the outstanding performance in applied fields, such as medical and agricultural sciences, and also in biotechnology, with shows that when good basic science takes place, high level goal oriented research also occurs.     

Dentistry scientometric analysis: a comparative study between Brazil and other most productive countries in the area

This research aims at performing a comparative study between the Brazilian scientific production in Dentistry, from 2000 to 2009 and countries that contribute with at least 2 % of the world’s scientific production indexed in the Scopus database. More specifically, we intend to assess the annual Brazilian scientific production by comparing it to the other countries’, analyze the Brazilian and other countries’ publications in journals with higher impact factors, as well as to highlight the scientific production from these countries and its international visibility, measured by its total and by its average of citations and normalized citation index per year, by comparing the countries, and to compare the index h of such countries. As work procedure, the SCImago Journal and Country Rank was used as source, identifying the group of producing countries in the Dentistry area from 1996 to 2009. From a total of 136 countries, 13 were highlighted as the most productive, each one of them accounting for at least 2 % the worldwide scientific production in the area. The following indicators were raised for each country: number of produced documents, total of citations, self-citations, average of citations per document and index h. We verified that Brazil is the only country in Latin America that is pictured among the most productive ones in the Dentistry area. We observed that Brazil presents a growing visibility and impact in the international scenery, what suggests that its production is constantly consolidating, with Brazilian scientific recognition in the main vehicles of dissemination in the area.     

Ten years of the genomic era in Brazil: Impacts on technological development assessed by scientific production and patent analysis

Over ten years ago Brazil entered the era of genome projects with the launch of its first sequencing effort. Since then, a series of projects have been undertaken in the country, greatly contributing to the formation of scientific research networks, related infrastructure and specialized labor. Today, Brazil’s competence in this area is internationally recognized and it is one of the main countries in the number of genomes sequenced. This article examines the effects of these genome initiatives on Brazilian technological innovation, through a broad bibliometric review, comprising the analysis of academic and patent publications, which revealed that the development of technology has not kept pace with scientific output.     

Knowledge linked to museum specimen vouchers: measuring scientific production from a major biological collection in Colombia

Biological collections are sources of knowledge, particularly critical to understand life when they house specimens from megadiverse countries. However, the scientific value of biological collections is usually unknown because the lack of an explicit link between knowledge and specimens. Here we compiled 628 papers from 152 journals that used collection objects from the Colecciones Biológicas del Instituto de Investigación de Recursos Biológicos Alexander von Humboldt, Colombia (IAvH-CB) as sources. The compilation was largely based on expert knowledge. However, to assess the performance of our method we compared our results with results obtained conducting automatic searches in academic databases. We calculated different metrics and depicted geographical, taxonomic, and bibliometric trends. We found that geographic coverage of the IAvH-CB objects used in the studies is largely regional or national. Taxonomically, we found records of 176 families in 61 orders of taxa, but there is large variation among the number of studies in different groups. The bibliometric analyses indicated that there is a growing trend in the number of publications and citations over the years, and that the citation number as well as the H index of this set of papers is comparable to the knowledge produced by major researchers in Colombia and of similar magnitude to that of the production of relatively small or medium sized collections in the USA. The compilation method used performed well, with broad coverage and an omission rate below 8%, compared with automated searches. However, we conclude that both approaches, expert knowledge and automated searches, are complementary. IAvH-CB are a massive source of scientific knowledge about Colombian biodiversity and they are instrumental for documenting basic issues about taxa in the country.     

Artificial intelligence and patents in Brazil: Overview on patentability and comparative study on patent filings

Innovations related to artificial intelligence (AI) can impact many technological fields and gather attention of several sectors from industry. Brazil is a developing country with a large territory and consumer market, attracting investment from foreign companies, including AI technologies. In the present work, we carry out a review of the Brazilian IP Law, Guidelines and Resolutions regarding patentability of AI inventions in Brazil, and also perform comparative analyses with the guidelines from the EPO and USPTO. Then, patent searches are carried out to analyze filing indicators of patent applications for AI inventions, wherein it is possible to verify that most of the filing applicants in Brazil are foreign companies, mainly from the US. Brazilian entities, which rank second overall in filing for patent applications in Brazil, do not even appear among the main applicants for AI inventions. We conclude that Brazil is not a competitive country in the production of patents related to AI, and it is important for Brazil to establish some degree of legal certainty regarding patent protection for AI inventions and disseminate knowledge about protecting such inventions by patents, so that inventors opt to disclose their AI inventions instead of keeping them as a trade secret. Therefore, more and more sectors of society might benefit from innovations arising from AI.     

A comparative study of communal practice: Assessing the effects of taken-for-granted-ness on citation practice in scientific communities

Summary Building on the findings of recent ethnographic studies of scientific practice, I develop and test theory about the impact of taken-for-granted-ness on citation practice in scientific communities. Using data gathered from special issues of scientific journals I find support for the hypothesized differences in the practices of natural and social science communities. Post hoc analysis uncovers evidence of a third pattern of citation practice associated in part with engineering and technology research, and evidence that organization studies and strategic management communities tend to employ extreme versions of social science citation practices. I discuss the implications of the study for our understanding of communities of practice, for our beliefs about differences between the branches of science, and about science as a productive enterprise.     

Inoculation of a submerged filter for biological denitrification of nitrate polluted groundwater: a comparative study

Activated sludge from a wastewater treatment plant and pure culture of Hydrogenophaga pseudoflava were utilized for the development of a denitrifying biofilm in a submerged filter in order to remove nitrate from polluted groundwater. Nitrate removal efficiency, nitrite accumulation, turbidity, COD and faecal indicators persistence in the treated water were determined at different superficial hydraulic loading (10, 20 and 30 m(3)/m(2) d) and superficial nitrate loading rates (1, 2, 3, 6 and 9 Kg NO(3)(-)/m(2) d) in the submerged filter. The application of H. pseudoflava as inocula allowed better results in terms of system stability, higher superficial hydraulic loading and superficial nitrate loading rates (30 m(3)/m(2)d and 9 kg NO(3)(-) /m(2) d, respectively). These values improve those obtained when the system was inoculated with activated sludge. In addition, the pure microbial inocula improved design parameters and running of the process due to its biofilm homogeneity, obtaining treated water with better characteristics to its final use as drinking water than that obtained with an activated sludge inocula.
