    O estudo da colaboração científica permite observar resultados que podem orientar a gestão da pesquisa em uma organização. Nesse sentido, o objetivo deste estudo é analisar a rede de colaboração científica em nanotecnologia na Empresa Brasileira de Pesquisa Agropecuária e sua evolução, considerando-se ser um tema que vem gerando resultados inovadores para o agronegócio brasileiro. Para tanto, foi empregada a metodologia de Análise de Redes Sociais, com o objetivo de perceber as relações de coautoria e de como analisar a evolução dessa rede de colaboração. Para trabalhar a perspectiva dos dados, foi escolhida a Base de Dados da Pesquisa Agropecuária, de acesso público, organizada e gerenciada pela Embrapa. A análise dos dados baseou-se na produção científica entre 2006 e 2014. Para a análise da evolução da rede, o período foi dividido em três fases: de 2006 a 2008, de 2009 a 2011 e de 2012 a 2014. Os dados, recuperados a partir do ano de 2006, permitiram compor um período significativo de análise de quase dez anos, evidenciando que a evolução da rede aconteceu de forma progressiva, e que a colaboração científica sobre o tema na Embrapa se torna cada vez mais efetiva e dinâmica.The study of scientific collaboration allows us to observe, for instance, results that can guide research management in an organization. In this sense, the objective of this study is to analyze the network for scientific collaboration in nanotechnology at the Brazilian Agricultural Research Corporation, and the evolution thereof, since this is a field which has produced innovative results for Brazilian agribusiness. To this end, the methodology of Social Network Analysis was used in order to identify co-authorship connections and to analyze the evolution of this network. The origin of the data was Agricultural Research Database (Base de Dados da Pesquisa Agropecuária), which is freely accessible to the public. The analysis was based on scientific production from 2006 to 2014. For the analysis of network evolution, this timeframe was divided into three periods, consisting of the periods from 2006 to 2008, 2009 to 2011, and 2012 to 2014. The results showed that the data represents a significant timeframe for analysis, nearly 10 years, providing the perception that, insofar as the evolution of the network is concerned, it evidently occurred in a gradual manner, highlighting the fact that scientific collaboration in nanotechnology at Embrapa becomes increasingly effective and dynamic

    Dissertação (mestrado)—Universidade de Brasília, Faculdade de Economia, Administração, Contabilidade e Ciência da Informação e Documentação, Departamento de Ciência da Informação e Documentação, 2009.Pesquisa exploratória, com dados quantitativos, que teve como objetivo verificar de que forma se processa o compartilhamento de informação e conhecimento entre os membros das equipes de desenvolvimento de software em organizações brasileiras de desenvolvimento de software, com base nas teorias de gestão da informação e do conhecimento. A literatura pesquisada mostrou a existência de facilitadores e barreiras ao compartilhamento de informação e conhecimento em equipes, e foi a base para a definição das variáveis de pesquisa. A coleta de dados se deu por meio de questionário eletrônico com escala de Likert, disponibilizado online, e respondido por 313 membros de equipes de desenvolvimento de software, contatados diretamente ou por meio de fóruns e listas de discussão na internet. Como resultado, a análise fatorial exploratória identificou a existência de cinco fatores que agregam as variáveis pesquisadas e explicam a influência dessas variáveis na percepção quanto ao compartilhamento de informação e conhecimento. Os dados obtidos sugerem que o repositório de informações da organização, o comportamento de compartilhamento dos membros das equipes de desenvolvimento de software, a estrutura organizacional, a confiabilidade das informações e o acesso a internet, estão entre os fatores mais importantes para o entendimento do compartilhamento de informação e conhecimento em equipes de desenvolvimento de software. ___________________________________________________________________________________ ABSTRACTExploratory research, using quantitative data, which aimed to verify how information and knowledge sharing works among members of software development teams from Brazilian software development organizations, based on theories of information and knowledge management. The searched literature has shown the existence of facilitators and barriers to sharing information and knowledge in teams, and was the basis for the variables definition in this research. The data werw collected through an electronic questionnaire with Likert scale, available online, and answered by 313 members of software development teams, contacted directly or through forums and discussion lists on the internet. As a result, exploratory factor analysis identified the existence of five factors that aggregate the variables and explain the influence of these variables in perceptions about the sharing of knowledge and information. The data suggest that the organization's repository of information, the sharing behavior of members of software development teams, organizational structure, the reliability of the information and access of the internet, are among the most important factors for understanding the information and knowledge sharing in software development teams

    NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

    Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data

    Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

    International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

    Growing knowledge: an overview of Seed Plant diversity in Brazil

    Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
