    This research proposes a performative / collaborative attitude on the part of the readers and revises the artistic processes of genesis that developed the interest of acting with a performance theater. In the process clues, the spectator's point of view is scaled up, mainly by the "mestizaje" of procedures with pedagogical processes, or pedagogical performances. Indicating other possibilities and ways of acting, and amplifying different corporeal revelations in the practices of groups of artists and collectives in Latin America. The idea of acting, especially for pedagogical activity, is oriented in the light of the book "The teacherinterpreter" (CIOTTI, 2014), which outlines these studies on the artistic-pedagogical procedure in “Scenic Disassembly” (CABALLERO, 2009). concept of Disassembly in the context of the extended scene (in performance), we conclude with the dimension of fragmentation practices as pedagogical action, under a more proactive look, and we realize that this research made possible an investigative and methodological course from the moment in which we come to experience them as an experience of artistic / pedagogical work.Esta pesquisa propõe uma atitude performativa / colaborativa por parte dos leitores e revisa os processos artísticos de gênese que desenvolveram o interesse de atuar com um teatro performático. Nas pistas dos processos, o ponto de vista do espectador é redimensionado, principalmente pela "mestiçagem" de procedimentos com processos pedagógicos, ou performances pedagógicas. Indicando outras possibilidades e modos de agir, e ampliando diferentes revelações corporais nas práticas de grupos de artistas e coletivos na América Latina. A ideia de atuação, especialmente para a atividade pedagógica, é orientada à luz do livro "O professor- performer”, (CIOTTI, 2014), que delineia esses estudos sobre o procedimento artístico-pedagógico na “Desmontagem Cênica” (CABALLERO, 2009). Examinamos o conceito de Desmontagem no contexto da cena estendida (em performance), concluímos com a dimensão das práticas de fragmentação como ação pedagógica, sob um olhar mais pró - ativo, e percebemos que esta pesquisa possibilitou um percurso investigativo e metodológico a partir do momento em que passamos a vivenciá-las como uma experiência de trabalho artístico / pedagógico

    O cajÃ, devido ao seu sabor diferenciado e agradÃvel, à um fruto bastante apreciado e consumido em diversas regiÃes do paÃs. Mas por apresentar uma elevada perecibilidade, torna-se necessÃrio o uso de tÃcnicas de processamento para estender sua disponibilidade para o consumo durante todo o ano. A desidrataÃÃo por liofilizaÃÃo apresenta como vantagem uma excelente retenÃÃo das caracterÃsticas nutricionais e sensoriais do fruto âin naturaâ. Para um aumento desta retenÃÃo e evitar aglomeraÃÃes no pÃ, por exemplo, pode ser feita a utilizaÃÃo de adjuvantes de secagem como a maltodextrina. Neste contexto, o trabalho teve como objetivo a aplicaÃÃo do processo de liofilizaÃÃo para obtenÃÃo da polpa de cajà em pÃ, caracterizaÃÃo fÃsica e fÃsico-quÃmica da polpa e do pà de cajÃ, acompanhamento da estabilidade durante o armazenamento e comportamento higroscÃpico dos ensaios. Com a realizaÃÃo dos ensaios do planejamento experimental, foi escolhido o ensaio de menor umidade, com 17% de maltodextrina e 24 horas de liofilizaÃÃo. A polpa apresentou caracterÃsticas semelhantes Ãs reportadas pela literatura, e uma concentraÃÃo dos constituintes ocorreu com a desidrataÃÃo da polpa. Quanto ao armazenamento, o ensaio controle (pà integral) teve uma vida Ãtil de 60 dias, diferentemente do ensaio contendo maltodextrina que apresentou boas caracterÃsticas durante todo perÃodo analisado. AlÃm disso, a maltodextrina exerceu funÃÃo protetora, evitando maiores perdas de constituintes quÃmicos e reaÃÃes fÃsicas no produto, como menor taxa de aumento de higroscopicidade, umidade e atividade de Ãgua. As isotermas de adsorÃÃo foram caracterÃsticas Ãs do tipo III. Os modelos matemÃticos de BET, GAB e Oswin foram os que melhor se ajustaram aos dados experimentais de sorÃÃo de umidade para o pà de cajà integral, e no pà da polpa de cajà com maltodextrina, o modelo de Henderson foi o que melhor se ajustou aos pontos experimentais do trabalho.The yellow mombin due to its distinctive flavor and pleasant, is a fruit highly appreciated and consumed in various regions of the country. But by presenting a high perishability, it becomes necessary to use processing techniques to extend its availability for consumption throughout the year. Dehydration by freeze-drying has the advantage of an excellent retention of nutritional and sensory characteristics of fresh fruit. To increase retention and to prevent agglomeration of the powder, for example, can be made the use of adjuvants drying such as maltodextrin. In this context, the work aimed at the implementation of the lyophilization process to obtain the pulp of yellow mombin powder, physical characterization and physicochemical pulp and powder yellow mombin, tracking stability during storage and hygroscopic behavior of the tests. With the tests of the experimental design was chosen to test lower humidity, with 17% maltodextrin and 24 hours of freeze drying. The pulp presented characteristics similar to reported by literature, and a concentration of constituents occurred with the pulp dehydration. As for storage, the test control (dried whole) had a useful life of 60 days, unlike the test containing maltodextrin that showed good characteristics throughout the period analyzed. In addition, maltodextrin exerted protective function, preventing further loss of chemical constituents and physical reactions to the product, such as lower rate of increase of hygroscopicity, moisture and water activity. The adsorption isotherms were the characteristics of type III. The mathematical models of BET, GAB and Oswin were the best fit to experimental data of moisture sorption for the full hog plum powder, and powder of hog plum pulp with maltodextrin, the Henderson model was the best fit to experimental points of work

    Systematics and Biogeography of New World Helicopsychidae (Trichoptera): Challenges in Facing Biodiversity Knowledge Shortfalls

    No full text
    Helicopsychidae is one of the most easily recognizable families, mainly due to the unique helical shape of the larval case, which resembles the shells of gastropod mollusks. Currently, 304 species are described in two genera, Rakiura McFarlane, monotypic and endemic to New Zealand, and Helicopsyche von Siebold. Helicopsyche has 303 species and a distribution in all biogeographic regions except Antarctica, with the greatest diversity found in the tropics. Taxonomic studies on the Helicopsychidae date back to the 19th century due to a misinterpretation of larval case. Only in 1856 the genus Helicopsyche was described based on the larval case of three species. Subsequently, Hagen transferred another four species to Helicopsyche. Misinterpretations were only resolved with the publication of Genera Insectorum by Ulmer, recognizing the genus as belong to the order Trichoptera. The phylogenetic relationships of the group were inferred by Schmid and, later, by Johanson with a large sample size. In a recent phylogenetic and biogeographic study on Sericostomatoidea, the previous hypotheses were refuted, and the relationship was proposed for the Neotropical subgenera Feropsyche Johanson and Cochliopsyche Müller. Feropsyche, the richest subgenus in species (127 species), was revised in 2002 and since then ca. 50 species have been described. However, distribution patterns, knowledge of semaphoronts and biological aspects remain poorly explored. On the other hand, Cochliopsyche, endemic to Neotropics and with only 17 species, was revised in 2003 and since then only distribution records and the description of one species have been made for the group. In this context, both groups, especially Cochliopsyche, have shortfalls in biodiversity knowledge related to species (Linnean shortfall), distribution patterns (Wallacean shortfall), knowledge of semaphoronts (Haeckelian shortfall) and knowledge of the evolution of the groups (Darwinian shortfall). In this context, this thesis aims to expand the knowledge of Helicopsychidae in the Neotropical region by describing new species and distributional patterns. In addition, a systematic revision of Cochliopsyche was performed, as well as the phylogenetic and biogeographic studies on the family. The results include the description of four new species of H. (Feropsyche) and the establishment of biogeographic patterns, potential distribution maps and the construction of a database with information on the group. The representatives of Dominican amber are removed from this subgenus based on phylogenetic results. Hypothesis are presented that the subgenus Feropsyche forms a lineage with the Australasian subgenus Saetotrichia. Cochliopsyche is resurrected to genus status based on phylogenetic and biogeographic results, and H. (Petrotrichia) as its sister group, with high support. In addition, a systematic revision of Cochliopsyche is provided, including standardized descriptions for all described species and description of five new species. In addition to Neotropical taxa, a phylogenetic proposal is presented for living and fossil species of Helicopsychidae, as well as a reconstruction of the ancestral area for the group. The legacy of this work is to be facing the shortfalls in Linnean, Wallacean and Darwinian knowledge of Neotropical taxa. The phylogenetic hypothesis presented suggests that the remaining subgenera of Helicopsyche form independent lineages, but due to the low support and taxon sampling, we are conservative and only indicate the need for more comprehensive work to test this hypothesis, preferring not to make taxonomic changes beyond the scope of this work.CAPESHelicopsychidae é uma das famílias mais facilmente reconhecíveis, principalmente pelo singular formato helicoidal dos abrigos larvais, que se assemelham às conchas de moluscos gastrópodes. Atualmente, 304 espécies estão descritas em dois gêneros, Rakiura McFarlane, monotípico e endêmico da Nova Zelândia, e Helicopsyche von Siebold. Helicopsyche apresenta 303 espécies e distribuição em todas as regiões biogeográficas, exceto Antártica. A maior diversidade deste gênero é encontrada nos trópicos. Os estudos taxonômicos sobre os Helicopsychidae iniciaram-se no século XIX a partir de uma má interpretação dos abrigos larvais. Somente em 1856 o gênero Helicopsyche foi descrito com base em abrigos larvais de três espécies. Posteriormente, Hagen transferiu outras quatro espécies para Helicopsyche. Os erros de interpretação só foram resolvidos com a publicação de Genera Insectorum por Ulmer, com o reconhecimento do gênero como pertencente à ordem Trichoptera. As relações filogenéticas do grupo foram inferidas primeiramente por Schmid e, posteriormente, por Johanson. Em um trabalho recente de inferências filogenéticas e biogeográficas para Sericostomatoidea, as hipóteses precedentes foram refutadas e foi recuperada uma relação entre os subgêneros Neotropicais Feropsyche Johanson e Cochliopsyche Müller. Feropsyche, o subgênero mais rico em espécies (127 espécies), foi revisado em 2002 e desde então ca. 50 espécies foram descritas. Porém, padrões de distribuição, conhecimento de semaforontes e de aspectos biológicos ainda permanecem pouco explorados. Na contramão, Cochliopsyche, endêmico da região Neotropical e com apenas 17 espécies, foi revisado em 2003 e desde então apenas registros de distribuição e descrição de uma única espécie foram feitos. Neste contexto, ambos os grupos, Cochliopsyche em especial, apresentam déficits de conhecimento da biodiversidade relacionados ao conhecimento das espécies (Déficit Linneano), padrões de distribuição (Déficit Wallaceano), de conhecimento dos semaforontes (Déficit Haeckeliano) e de conhecimento da evolução dos grupos (Déficit Darwiniano). Assim, a presente tese objetiva fornecer uma ampliação do conhecimento de Helicopsychidae na região Neotropical com descrição de novas espécies e dos padrões distribucionais. Para tanto, uma revisão sistemática de Cochliopsyche foi feita, assim como estudos filogenéticos e biogeográficos para a família. Como resultados temos a descrição de quatro novas espécies de H. (Feropsyche) e estabelecimento dos padrões biogeográficos, mapas de distribuição potencial e construção de base de dados com informações sobre este subgênero. Os representantes do âmbar Dominicano são retirados deste grupo com base em inferências filogenéticas. Também são aventadas hipóteses que o subgênero forme uma linhagem junto ao subgênero australasiano Saetotrichia. Cochliopsyche é reerigido ao status de gênero com base em inferências filogenéticas e biogeográficas, como grupo irmão dos H. (Petrotrichia) com alto suporte. Adicionalmente é fornecida uma revisão sistemática de Cochliopsyche, com fornecimento de descrição padronizada para todas as espécies e descrição de cinco espécies novas. Para além dos grupos Neotropicais, uma proposta filogenética entre os grupos viventes e fósseis de Helicopsychidae, assim como a reconstrução de área ancestral para o grupo. Como legado do trabalho temos o combate aos déficits de conhecimento Linneano, Wallaceano e Darwiniano para os grupos Neotropicais. A hipótese filogenética apresentada sugere que os subgêneros restantes de Helicopsyche constituam linhagens independentes, porém devido ao baixo suporte e amostragem taxonômica, seremos conservativos, apenas indicamos a necessidade de trabalhos mais abrangentes que testem essa hipótese, preferindo, assim, não realizar mudanças taxonômicas para além do escopo deste trabalho

    Ética na pesquisa em educação: análise de teses em uma universidade brasileira (2020–2022): ANALYSIS OF THESES IN A BRAZILIAN UNIVERSITY (2020-2022)

    This article investigates the “ethical gap” in Brazilian educational research through analysis of 181 doctoral theses defended between 2020 and 2022 at a public university. Grounded in Marxian-Lukacsian ontology, the study understands ethics as a complex of values mediating the individual-community relationship, constituting an ontological mark of the human condition. Adopting a mixed method with concurrent procedure, the research reveals that 23.93% of theses requiring specific ethical procedures did not adopt them, configuring a concerning gap in high-risk research. In-depth qualitative analysis evidences five critical dimensions: the persistence of the ethical gap in vulnerability contexts; the liberation from biomedical monopoly through CNS Resolution 510/2016; the need for ethics beyond “human subjects”; the methodological shockwave of 2022 (COVID-19 pandemic impact); and ethics as a formation problem, not a mere form. In a “publish or perish” era, the study questions whether pressures from academic capitalism justify neglecting ethics, concluding with the urgency of socially responsible science that recognizes ethics as formative praxis rather than bureaucratic obstacle.Este artigo investiga a “lacuna ética” na pesquisa educacional brasileira mediante análise de 181 teses de doutorado defendidas entre 2020 e 2022 em uma universidade pública. Fundamentado na ontologia marxiano-lukacsiana, o estudo compreende a ética como complexo de valores que medeia a relação indivíduo-comunidade, constituindo marca ontológica da condição humana. Adotando método misto com procedimento concomitante, a pesquisa revela que 23,93% das teses que demandavam procedimentos éticos específicos não os adotaram, configurando uma lacuna preocupante em pesquisas de alto risco. A análise qualitativa aprofundada evidencia cinco dimensões críticas: a persistência da lacuna ética em contextos de vulnerabilidade; a libertação do monopólio biomédico pela Resolução CNS 510/2016; a necessidade de ética além dos “sujeitos humanos”; a onda de choque metodológica de 2022 (impacto da pandemia COVID-19); e a ética como problema de formação, não mero formulário. Numa era de “publicar ou perecer”, o estudo questiona se pressões do produtivismo acadêmico justificam negligenciar a ética, concluindo pela urgência de uma ciência socialmente responsável que reconheça a ética como práxis formativa e não como obstáculo burocrático

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

    The 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.Brazilian Biodiversity Information System (SiBBr)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Brazilian

    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

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear understanding 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,5,6,7 vast areas of the tropics remain understudied.8,9,10,11 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 underrepresented in biodiversity databases.13,14,15 To worsen this situation, human-induced modifications16,17 may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities 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 organism 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 neglected 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 lost
