“Curadorias do invisível”: conhecimentos indígenas e o acervo etnográfico do Museu Paraense Emílio Goeldi

Based on our experience as members of the curatorial team of the Curt Nimuendaju Technical Reserve Ethnographic Collection at the Goeldi Museum (2011-2018), the purpose of this article is to reflect on the challenges of knowing, documenting, saving, conserving and disseminating collections of indigenous objects musealized, based on anthropological and museological research, but also considering our concerns about how to articulate and reconcile indigenous knowledge, perceptions, thoughts and feelings about the materiality, immateriality and agency of objects, and our expectations that this indigenous knowledge can contribute for intercultural management of musealized indigenous objects.Baseadas na nossa experiência como integrantes da equipe de curadoria  da Coleção Etnográfica Reserva Técnica Curt Nimuendaju do Museu Goeldi (2011-2018), o objetivo deste artigo é refletir sobre os desafios de conhecer, documentar, guardar, conservar e divulgar coleções de objetos indígenas musealizados, com base nas pesquisas antropológicas e museológicas, mas também considerando as nossas preocupações sobre como articular e conciliar conhecimentos, percepções, pensamentos e sentimentos indígenas sobre a materialidade, imaterialidade e agencialidade dos objetos, e as nossas expectativas de que estes conhecimentos indígenas possam contribuir para uma gestão intercultural dos objetos indígenas musealizados

Determination of Total Polyphenol Content in Food with the Flow-Injection

U ovom radu predložena je modificirana automatizirana metoda ubrizgavanja u protok za određivanje sadržaja ukupnih polifenola u namirnicama bazirana na Folin-Ciocalteauovoj reakciji u 0,5 mol L-1 NaOH. Metoda omogućuje automatiziranu analizu različitih uzoraka brzinom protoka 55 uzoraka na sat uz upotrebu galne kiseline kao standarda. Primjenom predložene metode na konkretne uzorke (bijelo i crno vino, zeleni, indijski te čaj od lipe, metvice i kamilice i bistri voćni sokovi od crnog ribiza i višnje), određen je njihov “indeks ukupnih polifenola” s većom repetibilnošću za razliku od ranije objavljenih metoda, manje ovisno o razrjeđenju uzorka. U odnosu na “batch” metodu, ova je metoda visoko tolerantna prema najčešćim interferentima (SO2, reducirajući šećeri i askorbinska kiselina). Rezultati dobiveni predloženom metodom pokazali su relativno slaganje s onima dobivenim referentnom Folin-Ciocalteauovom metodom.This paper describes an optimised flow-injection method for the determination of total polyphenol in food based on the Folin-Ciocalteau reaction in 0.5 mol L-1 NaOH. The method allows different types of samples to be analysed automatically at a rate of 55 samples per hour by using gallic acid as standard. By applying the proposed method to real samples (white and red wines, green, Indian, lime-tree, mentha and chamomile teas, and blackberry and cherry juices), their total polyphenol indices were determined with a higher reproducibility than obtained by earlier methods, whatever the dilution used. This method is highly tolerant towards the most common interferences (SO2, reducing sugars, and ascorbic acid) associated with the batch method. The results obtained by the proposed method relatively agree with those obtained using the referent Folin-Ciocalteau method

Phenolic compounds of Galega Vulgar and Cobrançosa olive oils along early ripening stages

In this study, the lipophilic and hydrophilic phenol composition of virgin olive oils (VOO) obtained from olives from two of the most important Portuguese cultivars (‘Galega Vulgar’ and ‘Cobrançosa’), harvested at different ripening stages and under two irrigation schemes (rain fed and irrigated), was evaluated. Phenolic alcohols (hydroxytyrosol and tyrosol), phenolic acids and derivatives and flavonoids (luteolin and apigenin), as well as tocopherols were quantified. Lipophilic (>300 mg kg 1) and hydrophilic phenols (>600 mg kg 1) were present in high contents in both VOO, for early ripening stages. Gamma-tocopherol content is higher in ‘Galega Vulgar’ VOO. Total phenols showed a decrease between ripening index 2.5 and 3.5. The dialdehydic form of elenolic acid linked to hydroxytyrosol (3,4-DHPEA-EDA), also known as oleacein, was the major phenolic compound identified in both oils. The concentration of free hydroxytyrosol and tyrosol in both VOO is very low while their esterified derivatives, like 3,4-DHPEA-EDA and p- HPEA-EDA, are much more abundantinfo:eu-repo/semantics/publishedVersio

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Effectiveness and safety of tocilizumab in patients with systemic sclerosis : a propensity score matched controlled observational study of the EUSTAR cohort

Objectives Tocilizumab showed trends for improving skin fibrosis and prevented progression of lung fibrosis in systemic sclerosis (SSc) in randomised controlled clinical trials. We aimed to assess safety and effectiveness of tocilizumab in a real-life setting using the European Scleroderma Trial and Research (EUSTAR) database. Methods Patients with SSc fulfilling the American College of Rheumatology (ACR)/EULAR 2013 classification criteria, with baseline and follow-up visits at 12±3 months, receiving tocilizumab or standard of care as the control group, were selected. Propensity score matching was applied. Primary endpoints were the modified Rodnan skin score (mRSS) and FVC at 12±3 months compared between the groups. Secondary endpoints were the percentage of progressive/regressive patients for skin and lung at 12±3 months. Results Ninety-three patients with SSc treated with tocilizumab and 3180 patients with SSc with standard of care fulfilled the inclusion criteria. Comparison between groups did not show significant differences, but favoured tocilizumab across all predefined primary and secondary endpoints: mRSS was lower in the tocilizumab group (difference -1.0, 95% CI -3.7 to 1.8, p=0.48). Similarly, FVC % predicted was higher in the tocilizumab group (difference 1.5 (-6.1 to 9.1), p=0.70). The percentage of progressive/regressive patients favoured tocilizumab over controls. These results were robust regarding the sensitivity analyses. Safety analysis confirmed previously reported adverse event profiles. Conclusion Although this large, observational, controlled, real-life EUSTAR study did not show significant effectiveness of tocilizumab on skin and lung fibrosis, the consistency of direction of all predefined endpoints generates hypothesis for potential effectiveness in a broader SSc population

Relatório Diagnóstico sobre o ensino superior e a ciência pós-covid-19 na Ibero-América : perspectivas e desafios 2022

O principal impacto no ensino a partir da declaração da pandemia foi a transição urgente e não planejada para modalidades de ensino remoto de emergência. A pandemia chegou e surpreendeu os países e instituições de ensino superior com capacidades diferentes para o desenvolvimento do ensino remoto de emergência e isso se refletiu nos resultados desiguais e nos desafios que tiveram que superar. Inicialmente apresentada como breve, a suspensão da presencialidade em muitos países da região ultrapassou 40 semanas e é o período sem aulas presenciais mais longo do mundo. A primeira reação das instituições foi criar comitês de crise para lidar com a emergência e garantir a continuidade do ensino de forma remota. A pandemia da covid-19 obrigou asinstituições universitárias a empreenderem esforços institucionais, acadêmicos,tecnológicos, etc., que não estavam em suas agendas e para os quais, em muitos casos,não houve preparação prévia. Esses esforços não foram apresentados de forma equilibrada no panorama regional. Embora as universidades da região já utilizassem plataformas virtuais de apoio ao ensino e à aprendizagem antes da pandemia, a maioria não eram propostas institucionais, mas sim iniciativas individuais. Esta foi a base para a continuidade da aprendizagem durante a emergência, e como a suspensão da presencialidade durou mais tempo, as instituições foram fortalecendo as propostas pedagógicas remotas de emergência no nível institucional, incorporando ferramentas e capacitação de professores. No nível institucional, para favorecer a continuidade da aprendizagem, as universidades não propuseram uma metodologia única, deixando para o pessoal docente a decisão sobre o uso das salas de aulas virtuais. Nelas, foram ministradas a maioria das aulas on-line sincronizadas, pelo menos em um primeiro momento. Embora os esforços das IES para oferecer apoio à comunidade universitária para garantir a continuidade da aprendizagem nas melhores condições possíveis sejam evidentes, havia limitações tecnológicas, tanto em termos de conectividade quanto de equipamentos, que nem sempre puderam ser cobertas. Também foram evidenciadas limitações pedagógicas, apesar do empenho para desenvolver competências básicas nos professores, visando facilitar o uso das possibilidades da educação a distância; e, por último, limitações socioemocionais, com esforços institucionais para reduzir a ansiedade e o stress gerados pelo isolamento e a desconexão social. A função de P&D universitária produziu um duplo movimento: por um lado, parou o planejamento e as ações em desenvolvimento até o surgimento da pandemia e, por outro, teve que disponibilizar e redirecionar recursos para produzir conhecimento sobre o SARS-CoV-2 e a covid-19, bem como para produzir recursos tecnológicos e auxiliar o sistema de saúde na prevenção do contágio, e no atendimento aos doentes e aos efeitos psicossociais da pandemia. As ações dos atores universitários para a contenção epidemiológica quanto à produção tecnológica e de conhecimento, são muito relevantes. Em alguns casos, surgiram de iniciativas institucionais nas IES com um histórico de capacidade de intervenção sociocomunitária e de articulação com o setor produtivo. Nesse sentido, as decisões políticas implementadas e os resultados obtidos foram, em maior ou menor grau, produto da articulação dos setores científicos e governamentais. No campo das IES, foram realizados muitos estudos e pesquisas sobre a SARS-CoV-2, a covid-19, a pandemia e seus efeitos em diferentes campos disciplinares. Em muitos casos, os esforços institucionais foram orientados para a produção e disponibilidade de recursos tecnológicos ou dispositivos de apoio social, especialmente para lidar com os efeitos dos processos do confinamento e luto pessoal. As pesquisas que não estão ligadas à covid-19 ou que não puderam ser mantidas foram adiadas em muitos países e podem enfrentar severas restrições para sua continuidade. Este risco é maior nas universidades dos países mais pobres que dependem de agências doadoras para o financiamento

Informe diagnóstico sobre la educación superior y la ciencia post COVID-19 en Iberoamérica : perspectivas y desafíos de futuro 2022

El principal efecto en la enseñanza a partir de la declaración de la pandemia fue la transición urgente y sin planificación previa a modalidades de enseñanza remota de emergencia. La desigual capacidad para el desarrollo de enseñanza remota de emergencia con que la pandemia sorprendió a países e instituciones del nivel superior, tiene su correlato en los desiguales resultados y los desafíos que tuvieron que superar. La supresión de la presencialidad, que se presentó inicialmente como breve, en muchos países de la región, superó las 40 semanas y se trata del cierre más prolongado a nivel mundial. La primera reacción de las instituciones fue la conformación de comités de crisis para hacer frente a la emergencia y garantizar la continuidad de la enseñanza de manera remota. La pandemia COVID-19 obligó a que las instituciones universitarias llevaran adelante una serie de esfuerzos institucionales, académicos, tecnológicos, etc., que no estaban en sus agendas y para los cuales, en muchos casos, no había preparación previa. Estos esfuerzos no se presentaron de manera equilibrada en el panorama regional. Si bien las universidades de la región utilizaban plataformas virtuales de apoyo a la enseñanza desde antes de la pandemia, estas no eran en su mayoría propuestas institucionales, sino iniciativas individuales. Esta fue la base de la continuidad pedagógica durante la emergencia y a medida que el cierre de la presencialidad se prolongó, las instituciones fueron fortaleciendo las propuestas pedagógicas remotas de emergencia a nivel institucional, incorporando herramientas e instancias de formación docente. Para favorecer la continuidad pedagógica, las universidades a nivel institucional no propusieron una única metodología, dejando estas decisiones de uso de las aulas virtuales al profesorado, desde donde se dictaron mayoritariamente clases sincrónicas virtualizadas, al menos en una primera instancia. Si bien se evidencian los esfuerzos de las IES para ofrecer soporte a la comunidad universitaria con el objetivo de garantizar la continuidad pedagógica en las mejores condiciones, existen limitaciones de orden tecnológico, ya sea de conectividad o equipamiento, que no siempre han podido ser cubiertos. También se evidenciaron limitaciones de orden pedagógico, pese a los esfuerzos destinados a desarrollar las competencias básicas en los docentes para facilitar el aprovechamiento de las posibilidades de la educación a distancia; y, finalmente, de orden socioemocional, con esfuerzos institucionales tendientes a reducir la ansiedad y el estrés que el aislamiento y la desconexión social generaron

BLOOM: A 176B-Parameter Open-Access Multilingual Language Model

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License

State of the climate in 2018

In 2018, the dominant greenhouse gases released into Earth’s atmosphere—carbon dioxide, methane, and nitrous oxide—continued their increase. The annual global average carbon dioxide concentration at Earth’s surface was 407.4 ± 0.1 ppm, the highest in the modern instrumental record and in ice core records dating back 800 000 years. Combined, greenhouse gases and several halogenated gases contribute just over 3 W m−2 to radiative forcing and represent a nearly 43% increase since 1990. Carbon dioxide is responsible for about 65% of this radiative forcing. With a weak La Niña in early 2018 transitioning to a weak El Niño by the year’s end, the global surface (land and ocean) temperature was the fourth highest on record, with only 2015 through 2017 being warmer. Several European countries reported record high annual temperatures. There were also more high, and fewer low, temperature extremes than in nearly all of the 68-year extremes record. Madagascar recorded a record daily temperature of 40.5°C in Morondava in March, while South Korea set its record high of 41.0°C in August in Hongcheon. Nawabshah, Pakistan, recorded its highest temperature of 50.2°C, which may be a new daily world record for April. Globally, the annual lower troposphere temperature was third to seventh highest, depending on the dataset analyzed. The lower stratospheric temperature was approximately fifth lowest. The 2018 Arctic land surface temperature was 1.2°C above the 1981–2010 average, tying for third highest in the 118-year record, following 2016 and 2017. June’s Arctic snow cover extent was almost half of what it was 35 years ago. Across Greenland, however, regional summer temperatures were generally below or near average. Additionally, a satellite survey of 47 glaciers in Greenland indicated a net increase in area for the first time since records began in 1999. Increasing permafrost temperatures were reported at most observation sites in the Arctic, with the overall increase of 0.1°–0.2°C between 2017 and 2018 being comparable to the highest rate of warming ever observed in the region. On 17 March, Arctic sea ice extent marked the second smallest annual maximum in the 38-year record, larger than only 2017. The minimum extent in 2018 was reached on 19 September and again on 23 September, tying 2008 and 2010 for the sixth lowest extent on record. The 23 September date tied 1997 as the latest sea ice minimum date on record. First-year ice now dominates the ice cover, comprising 77% of the March 2018 ice pack compared to 55% during the 1980s. Because thinner, younger ice is more vulnerable to melting out in summer, this shift in sea ice age has contributed to the decreasing trend in minimum ice extent. Regionally, Bering Sea ice extent was at record lows for almost the entire 2017/18 ice season. For the Antarctic continent as a whole, 2018 was warmer than average. On the highest points of the Antarctic Plateau, the automatic weather station Relay (74°S) broke or tied six monthly temperature records throughout the year, with August breaking its record by nearly 8°C. However, cool conditions in the western Bellingshausen Sea and Amundsen Sea sector contributed to a low melt season overall for 2017/18. High SSTs contributed to low summer sea ice extent in the Ross and Weddell Seas in 2018, underpinning the second lowest Antarctic summer minimum sea ice extent on record. Despite conducive conditions for its formation, the ozone hole at its maximum extent in September was near the 2000–18 mean, likely due to an ongoing slow decline in stratospheric chlorine monoxide concentration. Across the oceans, globally averaged SST decreased slightly since the record El Niño year of 2016 but was still far above the climatological mean. On average, SST is increasing at a rate of 0.10° ± 0.01°C decade−1 since 1950. The warming appeared largest in the tropical Indian Ocean and smallest in the North Pacific. The deeper ocean continues to warm year after year. For the seventh consecutive year, global annual mean sea level became the highest in the 26-year record, rising to 81 mm above the 1993 average. As anticipated in a warming climate, the hydrological cycle over the ocean is accelerating: dry regions are becoming drier and wet regions rainier. Closer to the equator, 95 named tropical storms were observed during 2018, well above the 1981–2010 average of 82. Eleven tropical cyclones reached Saffir–Simpson scale Category 5 intensity. North Atlantic Major Hurricane Michael’s landfall intensity of 140 kt was the fourth strongest for any continental U.S. hurricane landfall in the 168-year record. Michael caused more than 30 fatalities and $25 billion (U.S. dollars) in damages. In the western North Pacific, Super Typhoon Mangkhut led to 160 fatalities and$6 billion (U.S. dollars) in damages across the Philippines, Hong Kong, Macau, mainland China, Guam, and the Northern Mariana Islands. Tropical Storm Son-Tinh was responsible for 170 fatalities in Vietnam and Laos. Nearly all the islands of Micronesia experienced at least moderate impacts from various tropical cyclones. Across land, many areas around the globe received copious precipitation, notable at different time scales. Rodrigues and Réunion Island near southern Africa each reported their third wettest year on record. In Hawaii, 1262 mm precipitation at Waipā Gardens (Kauai) on 14–15 April set a new U.S. record for 24-h precipitation. In Brazil, the city of Belo Horizonte received nearly 75 mm of rain in just 20 minutes, nearly half its monthly average. Globally, fire activity during 2018 was the lowest since the start of the record in 1997, with a combined burned area of about 500 million hectares. This reinforced the long-term downward trend in fire emissions driven by changes in land use in frequently burning savannas. However, wildfires burned 3.5 million hectares across the United States, well above the 2000–10 average of 2.7 million hectares. Combined, U.S. wildfire damages for the 2017 and 2018 wildfire seasons exceeded $40 billion (U.S. dollars)
