The aim of this research was to investigate the dynamics of scientific production in the field of sustainable tourism, emphasizing the collaboration network, knowledge generated and the key authors and institutions that contribute to the advancement of knowledge.Information was collected from articles, books and proceeding papers using the Web of Science (WoS) platform from 1990 to 2018. A total of 7,051 documents were analyzed. Data were analyzed using network analysis and bibliometric indicators. Based on the information collected, scientific production linked on the economic pillar, particularly regarding terms such as sustainable tourism, tourism, management, sustainable development, sustainability, ecoturism and conservation. Thus, we found that the dynamics of collaboration in scientific production in sustainable tourism has a dense geographic network and proximity of themes as elements for structuring the knowledge network.
This study aimed to analyze the production and technological collaboration of biotechnology in Brazil through the patent documents granted by the National Institute of Industrial Property (INPI). Data analysis took place using the indicators of measures of technological activity and Social Network Analysis (SNA). The general panorama of biotechnological production, between 1982 and 2016, showed that the majority of patents (90%) are owned by non-residents, with emphasis on private companies. The main holder of biotechnologies in the country is the United States with 35.4% of the documents granted. SNA pointed to a weak technological collaboration between patent holders in biotechnology. The study showed that the public and private sectors have been responding to the demands presented by the Biotechnology Development Policy, but it is still necessary to strengthen the policies and actions already defined to improve the Brazilian bio industry. Among the indispensable actions is the dissemination of the culture of intellectual property about the protection of biotechnology for public institutions and the business sector.
A biodiversidade da Mata Atlântica é considerada de extrema importância biológica, mas essa riqueza de fauna e flora está ameaçada pelo desmatamento. O objetivo deste estudo consiste em apresentar um modelo de avaliação da perda da biodiversidade, adotando como cenário o município de Viçosa do Ceará, situado no Nordeste brasileiro. O método adotado baseia-se na proposição de um indicador em que se busca calcular a estimativa da perda da biodiversidade a partir do decréscimo da riqueza de aves, mamíferos e répteis escamados que fazem parte desse habitat, tendo como referência o modelo da relação espécie-área. Como resultados tem-se: (1) a perda da biodiversidade na área de estudo está em nível “extremo”; (2) as taxas de variação média e de velocidade têm movimento acelerado, logo, quanto maior for o aumento da área desmatada, mais rápida se torna a velocidade e aceleração da perda da biodiversidade; (3) a curvatura da função indicou que o ponto crítico da perda da biodiversidade acontece quando o desmatamento atinge 93% da área do ecossistema. Conclui-se que o modelo de estimativa da perda de aves, mamíferos e répteis escamados apresentou-se de forma eficiente para a avaliação da perda da biodiversidade no ecossistema de Mata Atlântica.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
