    OBJECTIVE: To estimate the prevalence of exclusive breastfeeding during maternity hospital stay (outcome) and to analyze the association between delivery in a Baby-Friendly Hospital (BFH) and the outcome. The hypothesis is that accreditation to this program improves exclusive breastfeeding during maternity hospital stay. Exclusive breastfeeding is essential in reducing neonatal morbidity and mortality. METHODS: This study is based on secondary data collected by the “Birth in Brazil: National Survey into Labour and Birth”, a population-based study, conducted with 21,086 postpartum women, from February 1, 2011, to October 31, 2012, in 266 hospitals from all five Brazilian regions. Face-to-face interviews were conducted mostly within the first 24 hours after birth, regarding individual and gestational characteristics, prenatal care, delivery, newborn’s characteristics, and breastfeeding at birth. A theoretical model was created, allocating the exposure variables in three levels based on their proximity to the outcome. This hierarchical conceptual model was applied to perform a multiple logistic regression (with 95%CI and p < 0.05). RESULTS: In this study, 76.0% of the babies were exclusively breastfed from birth until the interview. Babies born in public (AOR = 1.73; 95%CI: 1.10–2.87), mixed (AOR = 2.48; 95%CI: 1.35–4.53) and private (AOR = 5.54; 95%CI: 2.38–12.45) BFHs were more likely to be exclusively breastfed during maternity hospital stay than those born in non–BFHs, as well as those born by vaginal birth (AOR = 2.16; 95%CI: 1.79–2.61), with adolescent mothers (AOR = 1.83; 95%CI: 1.47–2.26) or adults up to 34 years old (AOR =1 .31; 95%CI: 1.13–1.52), primiparous women (AOR = 1.51; 95%CI: 1.34–1.70), and mothers living in the Northern region of Brazil (AOR = 1.99; 95%CI: 1.14–3.49). CONCLUSIONS: The Baby-Friendly Hospital Initiative promotes exclusive breastfeeding during hospital stay regarding individual and hospital differences

    Efforts have been made to find natural, highly nutritious alternatives to replace fish meal (FM) and fish oil (FO), which can simultaneously promote fish health and improve the nutritional quality of filets for human consumption. This study evaluated the impact of biofortified diets containing microalgae (as replacement for FM and FO), macroalgae (as natural source of iodine) and selenised yeast (organic source of selenium) on gilthead seabream growth, nutrient utilization, tissue composition and gene expression. A control diet (CTRL) with 15% FM and 5.5% FO was compared with three experimental diets (AD1, AD2, and AD3), where a microalgae blend (Chlorella sp., Tetraselmis sp., and DHA-rich Schizochytrium sp.) replaced 33% of FM. Diet AD1 contained 20% less FO. Diets were supplemented with Laminaria digitata (0.4% AD1 and AD2; 0.8% AD3) and selenised yeast (0.02% AD1 and AD2; 0.04% AD3). After feeding the experimental diets for 12 weeks, growth was similar in fish fed AD1, AD2, and CTRL, indicating that microalgae meal can partially replace both FM and FO in diets for seabream. But AD3 suppressed fish growth, suggesting that L. digitata and selenised yeast supplementation should be kept under 0.8 and 0.04%, respectively. Despite lower lipid intake and decreased PUFAs bioavailability in fish fed AD3, compared to CTRL, hepatic elovl5 was upregulated resulting in a significant increase of muscle EPA + DHA. Indeed, filets of fish fed AD2 and AD3 provided the highest EPA + DHA contents (0.7 g 100 g–1), that are well above the minimum recommended values for human consumption. Fish consuming the AD diets had a higher retention and gain of selenium, while iodine gain remained similar among diets. Upregulation of selenoproteins (gpx1, selk, and dio2) was observed in liver of fish fed AD1, but diets had limited impact on fish antioxidant status. Overall, results indicate that the tested microalgae are good sources of protein and lipids, with their LC-PUFAs being effectively accumulated in seabream muscle. Selenised yeast is a good fortification vehicle to increase selenium levels in fish, but efforts should be placed to find new strategies to fortify fish in iodineThis work has received funding from the European Union’s Horizon 2020 Research and Innovation Programe under Grant Agreement No. 773400 (SEAFOODTOMORROW) and from the project ATLANTIDA (ref.

    This article provides a re-examination of the main Afrocentric narrative of capoeira origins, the engolo or ‘Zebra Dance’, in light of historical primary sources and new ethnographic evidence gathered during fieldwork in south-west Angola. By examining engolo’s bodily techniques, its socio-historical context and cultural meanings, the piece emphasises its insertion into a pastoral lifestyle and highlights the relatively narrow ethnic character of the practice in Angola. This analysis and the comparison with capoeira helps us to develop certain hypotheses about the formation, migration, and re-invention of diasporic combat games between southern Angola and coastal Brazil, and more broadly, to increase our understanding of how African cultures spread across the southern Atlantic

    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

    Esta tese analisa a produção de biodiesel de soja no país e sua relação com o desmatamento da Floresta Amazônica. Tem como referência o Programa Nacional de Produção e Uso de Biodiesel (PNPB), criado em 2004 pelo Governo federal para promover a inserção de biodiesel ao diesel comum. A principal matéria-prima utilizada para atender a produção de biodiesel é a soja que vem se expandindo pelo país desde 1970. Sua cultura iniciou-se no Sul do país e avançou para a região central e, gradativamente, para o norte do Brasil, principalmente por meio de latifúndios monocultores mecanizados. A área de progresso da fronteira agrícola tem substituído o bioma local a Floresta Amazônica , o que tem sido motivo de preocupação diante do desmatamento exagerado e da perda da biodiversidade. O norte do estado do Mato Grosso apresentou um alto crescimento de produção de soja, que se expande pelas localidades degradadas pela criação de gado, as quais avançam sobre a Floresta. O objetivo deste trabalho foi discutir a produção do biodiesel no Brasil, no intuito de averiguar a questão ambiental, econômica e estratégica da inserção desse biocombustível no mercado brasileiro. Analisou-se a competência das políticas públicas estabelecidas a partir do PNPB, no que concerne a assegurar a sustentabilidade socioambiental do programa brasileiro de biodiesel e elaborou-se um Zoneamento Agroecológico do município de Sinop, localizado no norte do Mato Grosso, que tem produção de soja consolidada e é a interface entre o crescimento agropecuário e a Floresta Amazônica. Busca-se verificar a eficácia dessa ferramenta como instrumento de análise no que se refere aos diagnósticos ambientais. Foi averiguado que há incentivos governamentais para a expansão e a produção agrícola latifundiária no país por meio de recursos oferecidos ao setor, subsídios e flexibilização das leis ambientais, que promovem maior desmatamento da Floresta, sem preocupação com danos ambientais e recuperação dos ambientes degradados e ainda consolidam o país como exportador de matérias-primas. Já o Zoneamento Agroecológico baseado em dados secundários e praticamente sem custos, mostrou-se adequado para a gestão e o planejamento local, avaliou eficientemente as características físicas do ambiente e propôs um manejo correto para as áreas degradadas ou inseridas em um caminho de degradação.This thesis examines the production of soy biodiesel in the country and its relation to the deforestation of the Amazon rainforest. It is referenced to the National Program for Production and Use of Biodiesel PNPB (Programa Nacional de Produção e Uso de Biodiesel), created in 2004 by federal government to promoting the integration of biodiesel into diesel fuel. Soy is the main raw material for biodiesel production which has been expanded across the country since the 1970s. Its culture began in the south of Brazil and advanced into the central region, spreading gradually to the north, mainly through mechanized monoculture land properties. The agricultural expansion area to the north has replaced the local biome: the Amazon rainforest; such fact has worried since there are excessive deforestation and biodiversity loss. The northern of Mato Grosso State presented high growth of soybean production, which expands in the degraded areas by livestock that goes into the rainforest. The propose of this work is to discuss the Brazils biodiesel production to ascertain the environmental, economic and strategic issue of insertion of this biofuel in the brazilian trade. The efficiency of public policies was analyzed by the PNPB to ensure the socioeconomic sustainability of the Brazilian biodiesel program and a agro ecological zoning was elaborated from Sinop, county in northern of Mato Grosso which has soybean production consolidated and represents an interface between agricultural growth and Amazonia rainforest. This tools aim is to test its efficiency of a environmental diagnostics. It proved there is public issues that stimulated the agricultural expansion and production by resources, subsidies and environmental easing as changes in the law. That promotes deforestation without concern of ambient damages and repair of degraded environmental and also Brazil is consolidated as an exported of commodities. On the other hand, the ago ecological zoning based on secondary data and low costs has become a efficient tool to management and local planning, evaluating the environmental physical characteristics

    Esta dissertação analisa a produção de biodiesel de soja no país e sua relação com o desmatamento da Floresta Amazônica. Tendo como referência o Programa Nacional de Produção e Uso de Biodiesel PNPB, criado em 2004 no intuito de promover a inserção de biodiesel ao diesel comum, diminuindo a dependência externa do petróleo importado e agregando valor às produções do campo, verifica-se que, a matéria-prima principal de produção de biodiesel no Brasil é a soja, que vem se expandindo pelo país desde 1970. Sua cultura iniciou-se no sul do país e avançou para a região central, expandindo-se, gradativamente, ao norte do Brasil, principalmente por meio de latifúndios monocultores e controlados por grandes empresas transnacionais. A área de avanço agrícola ao norte tem substituído o bioma local: a Floresta Amazônica, o que tem preocupado entidades públicas e privadas, diante o desmatamento exagerado e perda da biodiversidade. O estado do Mato Grosso apresentou um alto crescimento de produção de grãos, principalmente de soja, e de desmatamento, nas últimas décadas. A região de São José do Xingu, localizada no norte do Mato Grosso, é interface entre o crescimento agrícola e a Floresta Amazônica, e foi escolhida como estudo de caso. Verificou-se que o desmatamento recente da Floresta na área de avanço agrícola está sendo promovido pela atividade pecuária, e os solos descampados e erodidos do pasto têm sido usados com a cultura de soja. Ou seja, a soja estabelece-se em áreas antes degradadas pelo gado e não diretamente sobre as áreas de floresta desmatada. Verificou-se, também, a potencialidade do norte do Mato Grosso para produção de biodiesel de soja para atender a demanda de um mercado regional, já que encontra-se tão distante do centro consumidor do país. Entretanto, São José do Xingu tem maiores entraves logísticos e tem sua produção de soja vinculada às empresas transnacionais localizadas na região, não tendo, a curto prazo, potencialidade para produção de biodiesel.This dissertation examines the production of soy biodiesel in the country and its relation to the deforestation of the Amazon rainforest. With reference to the National Program for Production and Use of Biodiesel PNPB (Programa Nacional de Produção e Uso de Biodiesel), created in 2004 with the aim of promoting the integration of biodiesel into diesel fuel, reducing dependence on foreign imported oil and adding value to the field productions, it is noted that the main raw material for biodiesel production in Brazil is soy, which has been expanded across the country since the 1970s. Its culture began in the south and advanced into the central region, spreading gradually to the north of Brazil, mainly through monoculture land properties controlled by large transnational corporations. The area of agricultural expansion to the north has replaced the local biome: the Amazon rainforest; such fact has worried both the public and private, since there are excessive deforestation and biodiversity loss. In recent decades, the state of Mato Grosso showed on the one hand a high growth of grain production, especially soybeans, and on the other hand deforestation. The region of Sao Jose do Xingu, located in northern Mato Grosso, represents an interface between agricultural growth and rainforest, and as such was chosen as a case study. It has been noticed that the recent deforestation of forest in the area of agricultural expansion is being promoted by the livestock industry, and soil eroded from the open fields and pastures have been recovered with the soybean crop. That is, soy is established in areas previously degraded by livestock, and not directly on the areas of cleared forest. Furthermore, it has been verified the potential of northern Mato Grosso to produce biodiesel from soybeans to meet the demands of a regional market, since it is so far from the consumer center of the country. However, Sao Jose do Xingu has greater logistical barriers and has its soybean production linked to transnational companies located in the region. Therefore, such region does not have, in the short term, potential for biodiesel production

    A produção de soja no Brasil alcançou destaque na última década. Atualmente, o país configura-se como maior exportador e segundo maior produtor de soja no mundo. Porém, a expansão desse cultivo está sendo associada diretamente ao desmatamento da Floresta Amazônica. Sua cultura iniciou-se no sul do país e avançou para a região central, sobre o bioma do cerrado, expandindo-se, gradativamente, ao norte do Brasil, principalmente por meio de latifúndios monocultores e controlados por grandes empresas transnacionais. A área de avanço agrícola ao norte tem substituído o bioma local: a Floresta Amazônica, o que tem preocupado entidades públicas e privadas, em face do desmatamento exagerado e perda da biodiversidade. Este estudo analisa o avanço da cultura da soja no norte do estado de Mato Grosso, no período entre 1984 e 2009, por meio da interpretação de imagens de satélite, e sua relação com o desmatamento da Floresta Amazônica. Como resultado, apresentam-se três mapas de uso do solo da área de estudo. A análise dos mapas permitiu verificar que o desmatamento recente da floresta está sendo promovido pela atividade pecuária, e os solos descampados e erodidos do pasto têm sido usados para a cultura de soja. Ou seja, na área analisada, a soja estabelece-se em áreas antes degradadas pelo gado, e não diretamente sobre as áreas de floresta desmatada

    A fronteira agrícola brasileira está avançando para o interior do país desde adécada de 1970. A princípio expandiu-se sobre o Cerrado e a região Centro-Oeste, comestímulo governamental barateando terras e valorizando a criação de gado bovino e ocultivo de grãos, como a soja. Atualmente, essas atividades dirigem-se gradativamente nosentido norte, ampliando-se sobre a Floresta Amazônica. O país tem destaque mundialcomo maior exportador e segundo maior produtor de soja no mundo e a expansão dessecultivo está sendo associada diretamente com o desmatamento da Floresta Amazônica, pormeio de latifúndios monocultores e controlados por grandes empresas transnacionais.
