Os desafios da pesquisa acadêmica sobre a Educação Domiciliar no Brasil

This paper aims to analyze the main challenges of academic research on homeschooling in Brazil today. Through a qualitative research approach, the elements analyzed are derived from both the literature on the subject and the monitoring of actions in favor of regularizing homeschooling in the country. The following highlight as predominant results: the reiterated use of common sense and generalizations in relation to home education; the reaction of opposition from the academic community on the subject that is associated with conservative projects of the current federal government; the need to expand dialogue and confront the polarization around the complex homeschooling movement; and the urgency of expanding academic research on home education in order to strengthen arguments in defense of public education.O presente artigo tem como objetivo analisar os principais desafios da pesquisa acadêmica sobre a educação domiciliar no Brasil na atualidade. Por meio de abordagem qualitativa de pesquisa, os elementos elencados para análise derivam tanto da pesquisa bibliográfica sobre o tema, como do acompanhamento das ações em prol da regulamentação da prática da educação domiciliar no país. Destacam-se como resultados predominantes: o uso reiterado do senso comum e generalizações em relação à educação domiciliar; a reação contrária da comunidade acadêmica sobre o tema que se encontra associado a projetos conservadores do atual governo federal; a necessidade de ampliação do diálogo e enfrentamento da polarização em torno de um movimento que se revela complexo; e a urgência da ampliação de pesquisas acadêmicas sobre a educação domiciliar visando ao fortalecimento dos argumentos em defesa da educação pública

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

The north-westward direction of distribution of the Pb-Zn deposits in North Macedonia, Serbia and Greece corresponds to the trend of the average density and temperature of the upper mantle. A similar direction is also noted in the structure of the Moho. The thickness of the sedimentary layer of the upper crust varies from 7.8 km in the areas of Dinaridе complexes and Serbo-Macedonian massif down to 100 m in the Vardar Zone. At the same time, the smallest thicknes is observed in the places of the densest distribution of Pb-Zn deposits. Blocks of the forming tectonic melange in the Vardar suture zone were squeezed up and eroded, which was possibly due to a decrease in the thickness of upper crust sedimentary layer and the lithosphere as a whole, as well as due to the high eclogitization of the lower ophiolite blocks. During the same period the deposits (Cu-Ni, SEDEX) previously formed due to ophiolites and rifts were exhumed as a result of uplifting and erosion processes and the new Cu-porphyry, skarn and / or vein (PbZn) deposits were formed during the magmatic arcs formation. Thus, the local area of the Besna Kobyla–Osogovo metallogenic zone containing the Sasa and Toranica deposits is the most eroded. Based on this conclusion, the southern direction of the zone seems to be prospective for new Pb-Zn deposits under the surface.
