Non-Timber Forest Products (NTFP), contribute to the livelihoods of over 6 million people in Amazon and over 4 million people in the Cerrado biomes. Here we explored data on the socio-ecology of extractivist landscapes at the biome scale in Amazonia and Cerrado in Brazil. We found that there are market chains for 45 and 58 NTFPs in Brazilian Amazon and Cerrado, respectively. Although there is a vast repertoire of empirical data for characterizing sociobiodiversity in Brazil this body of literature is mostly case-study driven, focusing on a very limited number of products and using different methodological approaches. Therefore, although there is a robust research legacy meaningful comparisons are very challenging. So far we have a fragmented view of vegetal extractivist dynamics at the biome scale. Our work contributes to upscale from the socioecology of individual NTFP to the biome scale encompassing a variety of products and its associated livelihoods.
The heritage issue, after nearly two centuries of discussion, is still full of myths and inconsistencies in keeping with the theory and practice of safeguarding assets and thematic accessibility. It is also known that the patrimony demarcates the memorial foundations of the collectivity and should serve the population from its socio-educational capacity, but, in practice, this often does not occur, resulting in the destitution of the sociocultural function of the good. The question of modern heritage makes the discussion even more ambiguous, promoting polemical debates, detaching the object from its historical value or framing its aesthetic value as mistaken. In this perspective, the choice of the object of study was based on the analysis of the set of the Palácio da Abolição and the Castelo Branco Mausoleum in Fortaleza (CE), as it is a significant landmark for the city in both a functional and formal aspect, housing the headquarters of the state government and composing a daring architectural ensemble in an important neighborhood in Fortaleza. However, looking at it in the semiological perspective of its architecture, it appears that the Mausoleum pays homage to the first president of the Brazilian dictatorial period, making it necessary, therefore, to raise a problematization related to the modern heritage and its function, under the memory architecture perspective.
Triangular Irregular Networks (TINs) are one of the most used ways to represent surface topology when working with Digital Terrain Models (DTM) or Geographic Information Systems (GIS). Given this form of representation, this article investigates one probabilistic demonstration to quantify how each point's accuracy σ (sigma) can be considered to have ambiguity, from the topological point of view, in any new 2D Delaunay Triangulation. To achieve it, this research designed an initial demonstration that, there is a maximum precision for which the network topology remains constant in a new Delaunay Triangulation, at each point and in the TIN as a whole. The methodological approach was experimental, with various mathematical experiments carried out using the Monte Carlo Simulation method. First, for each point of the network, and then for all network points for varied σ. The experiments culminate in helping to solve the problem of the existence of maximum σ for which the probability of occurrence in constant TIN topology is 100%. The mathematical results originated the following statement: Considering a TIN generated by Delaunay Triangulation, if any point of coordinates (x i , y i ) in a Triangular Irregular Network is disrupted (i.e., has its place altered), according to a Normal distribution N(μ, σ 2 ), then, exists a value σ max (sigma maximum) for which the topology of the network remains constant. For example, it was found that σ max.1 of one point exists and is obtained by σ max.1 = 0.30866, and at another point, σ max.2 = 0.2. The results also indicate the following for TIN: Every two-dimensional Triangular Irregular Network generated by the Delaunay Triangulation has a value σ * (sigma asterisk) to which the network topology remains constant. In this work, simulating the worst case of a Triangular Irregular Network: σ * = 0.2. Finally, it is concluded that the σ maximum for each point exists, as well as for the network as a whole. However, the results need to be tested in more extensive networks to prove (or not) if it always
A gestão ineficiente dos imóveis públicos federais ocasionada pela falta de incorporação, adequada destinação, controle e a fiscalização dos imóveis, permite com que diversos imóveis sem uso sofram ações externas que ocasionam problemas socioambientais. Para enfrentar estes problemas de gestão, a Secretaria de Patrimônio da União (SPU), órgão responsável pelo patrimônio da União, criou em 2017 o Programa de Modernização da Gestão do Patrimônio Imobiliário da União (PMGPU), visando fortalecer a capacidade de otimizar a administração dos imóveis, objetivando a correta incorporação ao Patrimônio. Este artigo procura apresentar as ações desenvolvidas para a otimização da gestão do patrimônio e resultados do trabalho realizado pela Unidade Regional de Geoinformação de Minas Gerais (URGeo/MG) na integração do PMGPU no âmbito da SPU/MG. A metodologia desenvolvida na pesquisa envolve a padronização da cartografia, incluindo a catalogação e conversão dos produtos; criação de Banco de Dados Geográfico; modernização de procedimentos de identificação e caracterização de imóveis. Pelas ações desenvolvidas após a execução da metodologia foram identificados e tratados 3394 produtos cartográficos no estado de Minas Gerais no período de 2017 a 2020. O resultado obtido permitiu a URGeo/MG obter um inventário de suas coleções e responder satisfatoriamente ao PMGPU, bem como ter um processo adaptado às características da documentação dos imóveis sob sua responsabilidade.
A alta letalidade da COVID-19 traz evidente a necessidade da identificação dos potenciais grupos de risco da doença. A disseminação da COVID-19 pode ser melhor compreendida com estudos epidemiológicos combinados com avaliações socioeconômicas das populações afetadas. O objetivo desta pesquisa foi usar análise espacialmente explicitas para analisar a influência de atributos socioeconômicos e de saúde na disseminação viral de COVID-19 no estado de Minas Gerais por meio de regressões múltiplas e espaciais. Os dados socioeconômicos foram coletados na plataforma do Instituto de Pesquisa Econômica Aplicada, e posteriormente, foram construídos modelos de regressão incluindo modelos de erro espacial “spatial error models” (SEMs) e de defasagem espacial “spatial lag models” (SLMs) para as variáveis número de casos “Cases” e óbitos “Deaths” por COVID-19. Para as condições socioeconômicas e pandêmicas encontradas no estado de Minas Gerais, o SEM adequou-se melhor para variável dependente ‘Cases’ e o SLM para a variável dependente ‘Deaths’. Os resultados mostram que municípios com maior longevidade, infraestrutura urbana municipal, e menor fluxo de pessoas em transportes públicos apresentam menores ocorrências de óbitos por COVID-19. Este trabalho fornece subsídios a políticas de mitigação de risco de pandemia e melhor gerenciamento de recursos médicos.
