    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

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

    Tactical media in Brazil: information and communication dynamics

    No full text
    This paper aims to contribute to studies about resistance, offering an analysis of the limits and possibilities of the use of Internet by dissident groups as the digital information and communication networks are becoming central in social life organization, production processes and accumulation of wealth. The tactical media concept, elaborated by Garcia and Lovink (1997), is understood as an attempt to highlight new forms of political action made possible by the popularization of information and communication technologies (ICTs), in order to introduce an analysis of informational dynamics and communication in the World Wide Web by tactical media groups in Brazil. The research about Internet use by tactical media groups in Brazil reveals local characteristics and a concentrated use for activism purposes, as a way of sharing information, mobilization and coordination of activities by individuals or groups with a common goal. Four examples of action are detailed: Movimento dos Sem Satélite (Satelliteless Movement MSST), parody blog Falha de São Paulo, assina: do texto ao contexto , project by Cícero Dias da Silva and the idea of MetaReciclagem This work adopts the approach of Operaism theories, in which the changes originated by the biopolitical production are not restricted to the economic field, but also transforms ontological and social fields - which are considered an opportunity for groups interested in promoting social transformationCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorO trabalho pretende contribuir para estudos no campo da resistência a partir da análise dos limites e as possibilidades do uso da Internet por grupos dissidentes uma vez que as redes digitais de informação e comunicação estão se tornado elementos centrais na organização da vida social, dos processos produtivos e da acumulação de riqueza. Para tal, apropria-se do conceito de mídias táticas, formulado por Lovink e Garcia (1997), aqui entendida como uma tentativa de nomear novas formas de ação política viabilizadas pela popularização de tecnologias de informação e de comunicação (TICs), para apresentar a apropriação da rede mundial de computadores por grupos de mídias táticas no contexto brasileiro. O levantamento sobre a apropriação da rede mundial de computadores por grupos brasileiros em mídias táticas apresenta especificidades locais e usos concentrados no campo do ativismo on-line como forma de compartilhamento de informação, mobilização e coordenação de atividades por indivíduos ou grupos com objetivo comum. São detalhadas as ações do Movimento dos Sem Satélite (MSST), blog-paródia Falha de São Paulo, Projeto assina: do texto ao contexto , de Cícero Dias da Silva e a ideia de MetaReciclagem Adota-se a abordagem proposta pelos teóricos do Operaismo, em que as transformações advindas da produção biopolítica não estão restritas ao campo econômico, mas proporcionam mudanças estruturais nos terrenos ontológicos e sociais o que é considerado uma oportunidade para grupos interessados em promover transformação social

    Novos cadernos de laboratório e novas culturas epistêmicas: entre a política do experimento e o experimento da política

    We describe and analyze new epistemic cultures (KNORR-CETINA, 1999) that are being engendered by two emerging modes of science - Open Science and Common Science - that, despite numerous differences, converge on two aspects: the critique of scientific fact and their strategy of transforming laboratory notebooks into their main literary technology. We have adopted the notion of epistemic culture to operationalise our analysis of knowledge production systems strategies to configurate technologies, epistemic objects and subjects that, in turn, create effects of truth. To do so, we are inspired by laboratory ethnographies and Shapin and Shaffer's (1985) "three technologies" approach elaborated to explain how natural philosophers of the seventeenth century constructed the notion of scientific fact (matter of fact) so solid that it became synonym of science. Similarly, we aimed to understand how emerging modes of science seek to legitimize new ways of producing knowledge and disputing the very notion of science. In the contemporary Open Science movement, we approach open notebook science, proposed in 2006 by professor and researcher in Chemistry Jean-Claude Bradley as "a way of doing science in which - in the best possible way - you make all your research free and accessible to the public in real time" (BRADLEY, Sep 2010). We entered his "open laboratory" through documentary research that identified the open notebook as the main element of a complex ecosystem of open collaboration. Articulated with new social and material technologies, this literary technology aims to replace a science based on trust with one based on transparency and data provenance. Its epistemic culture does not impose a scientific fact as a sine qua non condition for knowledge communication, but values, above all, the adequate record of experimental practice whatever its outcome is - an epistemic culture that we have named a "matter of proof", given its emphasis on documentation. In Common Science (LAFUENTE, ESTALELLA, 2015), we investigated the open notebook of citizens' laboratory (CALC in spanish) prototyped by Antonio Lafuente and documentation practices of mediator- researchers at Medialab Prado, a public institution in Madrid that calls itself a "citizen's laboratory". Here, the critique of scientific fact dialogues with Latour´s compositionism since it is understood as an (important) subset of reality, which, however, should not supersede political debates, but rather relate to “matters of concern". In this perspective, the epistemic modernization process would foster a "third sector of knowledge" that would dispute the anticipatory governance of technoscientific subjects (LAFUENTE, 2007). Our participant observation has observed that current documentation practices tend to reproduce the logic of a cultural production field that fosters new political imaginaries, but does not initiate the knowledge accumulation cycle that would transform citizen laboratories into centre of calculation (LATOUR, 2000). Promoters tend to reduce communication to publicity of activities, attracting potential participants; or accountability, to prove that they carried out the projects.Descrevemos e analisamos novas culturas epistêmicas (KNORR-CETINA, 1999) que estão sendo engendradas por dois modos de ciência emergentes – a Ciência Aberta e a Ciência Comum – e que, apesar de inúmeras diferenças, convergem na crítica à noção de fato científico e na estratégia de transformar o caderno de laboratório em sua principal tecnologia literária. Adotamos a noção de cultura epistêmica para operacionalizar nossa análise sobre estratégias para configuração de objetos, tecnologias e sujeitos epistêmicos por sistemas de produção de conhecimento que, por sua vez, criam efeitos de verdade. Para tal, nos inspiramos nas etnografias de laboratório e na abordagem das “três tecnologias” de Shapin e Shaffer (1985) para explicar como os filósofos naturais do século XVII construíram a noção de fato científico (matter of fact) como uma “variedade de conhecimento” tão sólida que se tornou sinônimo de ciência. De modo análogo, procuramos compreender como os modos de ciência emergentes pretendem legitimar novas maneiras de produzir conhecimento e disputar a própria noção de ciência. No movimento contemporâneo da Ciência Aberta, abordamos o open notebook science, tal como proposto em 2006 pelo professor e pesquisador em Química Jean-Claude Bradley como “uma maneira de fazer ciência na qual – da melhor maneira possível – você torna toda a sua pesquisa livre e acessível ao público em tempo real” (BRADLEY, set 2010). Adentramos seu “laboratório aberto” através de uma pesquisa documental que identificou o caderno aberto como principal elemento de um complexo ecossistema de colaboração aberta. Articulada com tecnologias sociais e materiais, esta tecnologia literária pretende substituir uma ciência baseada na confiança por outra fundamentada na transparência e na proveniência dos dados. Sua cultura epistêmica não impõe a obtenção de um fato científico como condição sine qua non para a comunicação de conhecimento novo, mas valoriza, sobretudo, o registro adequado da prática experimental seja qual for seu resultado – o que chamamos de matter of proof pela ênfase na documentação. Já na Ciência Comum (LAFUENTE, ESTALELLA, 2015), abordamos o caderno aberto de laboratório cidadão (CALC) prototipado por Antonio Lafuente e práticas de documentação de pesquisadoras-mediadoras do Medialab Prado, instituição pública madrilenha se autodenomina “laboratório cidadão”. Aqui, a crítica à noção de fato científico dialoga com o composicionismo latouriano ao compreendê-lo como um (importante) subconjunto da realidade que, no entanto, não deve se sobrepor aos debates políticos, mas conectar-se às “questões de interesse” (matter of concern). Nesta perspectiva, a modernização epistêmica fomentaria um “terceiro setor do conhecimento” que disputaria a governança antecipatória de assuntos tecnocientíficos (LAFUENTE, 2007). Nossa observação participante identificou que as práticas atuais de documentação tendem a reproduzir a lógica do campo da produção cultural que fomenta novos imaginários políticos, mas não inicia o ciclo de acumulação de conhecimento que o transformaria os laboratórios cidadãos em centros de cálculo (LATOUR, 2000). Os promotores de atividades tendem a reduzir a comunicação à divulgação de atividades para atrair participantes em potencial ou a prestação de contas, comprovando a realização de atividades

    O objetivo deste trabalho foi comparar os domínios vegetacionais descritos por Saint-Hilaire, em 1817, às classificações fitofisionómicas atuais para a região entre Diamantina, Serro e Minas Novas, Minas Gerais, Brasil. Elaborou-se um banco de dados a partir da análise de suas obras da vegetação para o trajeto percorrido e realizou-se etapas de campo. Foram elaborados mapas de vegetação atual e cobertura da terra de três caminhos percorridos pelo naturalista. Os domínios vegetacionais matas virgens, catingas, carrasqueiros, carrascos e campos naturais foram descritos para a área de estudo e compararam-se às fitofisionomias atuais são denominadas Florestas Estacionais Semidecíduas e Decíduais, Caatinga Arbórea Aberta; Cerrado Denso, Típico, Ralo e Rupestre; Campo Sujo, Limpo e Rupestre, respectivamente. O naturalista descreveu áreas antropizadas como Capoeiras e Campos Artificiais. As comparações entre descrições antigas e atuais mostraram-se viáveis e relevantes. Estas informações contribuem com dados ecológicos, biológicos e geográficos a subsiduarem investigações científicas e estratégias para a conservação dos recursos naturais dos biomas brasileiros
