Abstract This article considers how relations with certain plants produce multiple temporalities for the Wajãpi, an Amerindian people from the Brazilian Amazon. Inspired by a non-anthropocentric anthropology or an "anthropology beyond the human," the article is an ethnographic exploration about how the Wajãpi perceive the concrete and sensible features of certain vegetable species, and thus how they see them as subjects, in a process that produces different space-times. I also show how certain concepts are central to this same process, specifically, that of life cycle and maturation (including death), which lead to notions of co-temporality and difference between groups and individuals.

Resumo Pretendo explorar neste artigo as relações entre os domínios da roça (koo) e da floresta (ka'a), importante oposição da cosmologia wajãpi (grupo Tupi que habita o estado do Amapá). Ka'a e koo, contudo, não se constituem como uma oposição fixa, mas antes como posições relacionais que se movem, nas quais a capoeira ocupa um papel fundamental. Algo que é evidenciado tanto numa dinâmica de ocupação territorial - por meio do cultivo de áreas de mata primária e o abandono dos roçados após a colheita -, quanto por meio das relações perspectivistas que movimentam as categorias de roça e floresta, plantas cultivadas e não-cultivadas, através de distintos sujeitos. Nesse contexto, compreender a dinâmica das relações entre floresta e roçado é fundamental para melhor refletir sobre como algumas famílias wajãpi entendem a atividade agrícola. Proponho essa reflexão estabelecendo um diálogo com ecologia histórica que aponta para a existência de florestas antropizadas, contexto em que a agricultura se apresenta como uma atividade central para a produção de biodiversidade.

PurposeThis study explores how excellence models can leverage digital transformation on the path to sustainable development in organisations.Design/methodology/approachA survey was used to study the different facets of digital capabilities and their impact on sustainable development success of organisations holding an external recognition from the European Foundation for Quality Management (EFQM). Partial Least Squares structural equation modelling (PLS-SEM) combined with Necessary Condition Analysis (NCA) were used to analyse data.FindingsInternalising excellence practices is decisive in mediating effective digital capabilities to achieve sustainable development. To achieve high levels of sustainable development success, organisations must achieve high levels of excellence practices internalisation, which are much more important than the excellence model external recognition.Research limitations/implicationsThis study addresses essential issues with theoretical and practical value but is limited to a sample of organisations with EFQM recognition in two countries. Future studies should address different organisations and cultural environments.Practical implicationsThe findings are relevant for organisations facing digital transformation and sustainable development challenges. They are essential for managers leveraging digital capabilities to capitalise on practices and processes and achieve Sustainable Development Goals. Organisations can benefit from a multidimensional approach to digital capabilities when struggling against external challenges.Originality/valueThis study closes a research gap regarding the impact of digital capabilities on sustainable development success. It is the first empirical study to combine sufficiency and necessity conditions analyses to explore the mediating role of excellence practices internalisation and one of the first to address digital capabilities from a multidimensional perspective.

Leadership is crucial in organizational life. Positive leadership is marked by transparent, trust-based leader–follower relationships that significantly boost employees' dedication and engagement. Work engagement stems from a positive bond between workers, their job, and their organization. Authentic leadership, in particular, has been found to enhance work engagement, but this relationship is quite complex. Prior studies have explored the psychological processes linking organizational context and work-related attitudes and provided intriguing insights, such as that employees consider work to be part of their identity and that positive work experiences enrich family life. This research more closely examined authentic leadership's impact on work engagement, including the mediating effect of meaningful work and work–family enrichment. A cross-sectional study was conducted with data from various organizations' employees (number = 292). Multiple regression analyses' results support the theoretical model, confirming a significant positive link between perceived authentic leadership and work engagement. These variables are directly and indirectly related through the proposed mediators. Implications for human resource management are discussed, especially strategies that increase work environments' positive impacts on work engagement.

Resumo: O presente estudo analisa a participação política de mulheres na América Latina a partir da presença delas nos legislativos nacionais. São privilegiados fatores institucionais, destacadamente duas variáveis: existência ou não de cotas de gênero e formato de lista eleitoral (aberta ou fechada). Objetiva-se responder se a combinação de lista fechada e existência de cotas potencializa a eleição de mulheres nas câmaras baixas ou únicas de 14 países latino-americanos. São levantados dados históricos da presença de mulheres, os quais permitiram agrupar os casos em três conjuntos, posteriormente analisados de forma qualitativa. O estudo permitiu confirmar a hipótese do efeito cumulativo, tendo os países que apresentam as duas variáveis demonstrado os melhores resultados; ao mesmo tempo, questioná-la, em parte, ao identificar países como o Equador, o qual está entre os que possuem maior porcentagem e apresenta somente uma das variáveis.

Resumo A realização de estudos de impacto ambiental (EIA) prévios à implantação de grandes empreendimentos é obrigatória no Brasil. Porém, os critérios normativos para delimitação de áreas de influência são considerados imprecisos e insuficientes. O presente artigo busca demonstrar como impactos ambientais em série causados pela implantação de usinas hidrelétricas e por projetos de mineração industrial no Amapá desencadearam surtos de malária e de leishmaniose tegumentar americana (LTA) na Terra Indígena Wajãpi e em outros assentamentos da região central do estado. Análises espaciais de desmatamento, curvas de variações climáticas e cronologia de impactos de tais empreendimentos, feitas entre 2003 e 2015, foram utilizadas para verificar a correlação de efeitos na saúde em comunidades não incluídas durante as diversas fases do licenciamento para implantação destes empreendimentos. Os resultados demonstram que surtos de malária e de LTA estiveram correlacionados com aumento das taxas de desmatamento causado pela expansão de assentamentos rurais, mas principalmente pela implantação de duas usinas hidrelétricas e intensificação de atividades de mineração industrial de ouro e de ferro, assim como o consequente incremento de garimpos na região. Os resultados explicitam a fragilidade do processo de licenciamento ambiental para delimitação de áreas de influência indireta, principalmente relacionados a aspectos da saúde.

The polyphenol resveratrol (3,5,4-trihydroxystilbene) is a well-known plant secondary metabolite, commonly used as a medical ingredient and a nutritional supplement. Due to its health-promoting properties, the demand for resveratrol is expected to continue growing. This stilbene can be found in different plants, including grapes, berries (blackberries, blueberries and raspberries), peanuts and their derived food products, such as wine and juice. The commercially available resveratrol is usually extracted from plants, however this procedure has several drawbacks such as low concentration of the product of interest, seasonal variation, risk of plant diseases and product stability. Alternative production processes are being developed to enable the biotechnological production of resveratrol by genetically engineering several microbial hosts, such as Escherichia coli, Corynebacterium glutamicum, Lactococcus lactis, among others. However, these bacterial species are not able to naturally synthetize resveratrol and therefore genetic modifications have been performed. The application of emerging metabolic engineering offers new possibilities for strain and process optimization. This mini-review will discuss the recent progress on resveratrol biosynthesis in engineered bacteria, with a special focus on the metabolic engineering modifications, as well as the optimization of the production process. These strategies offer new tools to overcome the limitations and challenges for microbial production of resveratrol in industry. ; We would like to thank the European Union Framework Program 7 "BacHBerry" (http://www.bachb erry.eu), Project No. FP7-613793 for financial support, the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/BIO/04469 unit, COMPETE 2020 (POCI-01-0145FEDER-006684) and BiotecNorte operation (NORTE-01-0145FEDER-000004) funded by the European Regional Development Fund under the scope of Norte2020 - Programa Operacional Regional do Norte. ...

BACKGROUND The growing interest in polyphenols has led to the design of industrial-scale processes able to produce them by fermentation and recover them in a more sustainable way. The goal of this work is to present two integrated approaches for the recovery of resveratrol, obtained through fermentation. The production of resveratrol using Corynebacterium glutamicum and its continuous removal using a hydrophobic resin is described. Batch production is compared with in situ product removal, where Amberlite XAD-7HP is either directly added to the medium (direct adsorption) or is present in an external column (external adsorption). RESULTS For both adsorption strategies tested, the amount of extracellular resveratrol increased from 75% to at least 90% of the total amount produced. However, lower total resveratrol concentrations were attained 3.6 and 2.2mg L-1, for the external and direct contact strategies, respectively, versus 5.3mg L-1 for batch experiments. CONCLUSIONS The proposed in situ removal strategies demonstrated the potential of increasing the excretion of resveratrol produced intracellularly. These process configurations may not only lead to a simpler downstream process design, but also to the avoidance of potential problems with the toxicity of polyphenols to the cells, especially when larger titers are obtained. © 2017 Society of Chemical Industry ; We would like to thank the European Union Framework Program 7 'BacHBerry' (www.bachberry.eu), Project No. FP7- 613793 for financial support, the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/BIO/04469/2013 unit, COMPETE 2020 (POCI-01- 0145-FEDER-006684) and BioTecNorte operation (NORTE-01-0145- FEDER-000004) funded by the European Regional Development Fund under the scope of Norte2020 - Programa Operacional Regional do Norte. ...

In recent years microorganisms have been engineered towards synthesizing interesting plant polyphenols such as flavonoids and stilbenes from glucose. Currently, low endogenous supply of malonylCoA, indispensable for plant polyphenol synthesis, impedes high product titers. Usually, limited malonylCoA availability during plant polyphenol production is avoided by supplementing fatty acid synthesisinhibiting antibiotics such as cerulenin, which are known to increase the intracellular malonylCoA pool as a side effect. Motivated by the goal of microbial polyphenol synthesis being independent of such expensive additives, we used rational metabolic engineering approaches to modulate regulation of fatty acid synthesis and flux into the citric acid cycle in Corynebacterium glutamicum strains capable of flavonoid and stilbene synthesis. Initial experiments showed that sole overexpression of genes coding for the native malonylCoAforming acetylCoA carboxylase is not sufficient for increasing polyphenol production in C. glutamicum. Hence, the intracellular acetylCoA availability was also increased by reducing the flux into the citric acid cycle through reduction of citrate synthase activity. In defined cultivation medium, the constructed C. glutamicum strains accumulated 24 mg/L (0.088 mM) naringenin or 112 mg/L (0.49 mM) resveratrol from glucose without supplementation of phenylpropanoid precursor molecules or any inhibitors of fatty acid synthesis. ; We would like to thank the European Union Framework Program 7 ''BacHBerry'' (www.bachberry.eu), Project No. FP7‐ 613793 for financial support and also the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/ BIO/04469 unit, COMPETE 2020 (POCI‐01–0145‐FEDER‐006684) and BiotecNorte operation (NORTE‐01–0145‐FEDER‐000004) funded by the European Regional Development Fund under the scope of Norte2020 ‐ Programa Operacional Regional do Norte.
