Similarity and income content at the international trade: The case of BRICS during the period 2000/09

This study aimed to calculate the patterns of similarity and income content of Brazilian, Russian, Chinese and Indian exports by means of indexes, and compare those patterns with those of OECD countries, covering a period between 2000 and 2009. The results indicate that Brazilian, Russian, Chinese and Indian exports became more similar between 2000 and 2006, but that similarity has declined ever since. Exports from China and India, in turn, are increasingly similar to each other and less different from the exports of OECD countries. Export sophistication has increased over the years, with higher growth rates in China and India. India and Russia's sophistication indexes surpassed that of Brazil in 2007, which signal that those countries currently export products with higher content of income. The study also indicated that Brazil has been losing market share for China and India as an exporter of sophisticated products. --Exports,Brazil,Russia,China,India,similarity,income content

Behavioural Insights Applied to Policy - European Report 2016

This report covers a wealth of policy initiatives across 32 European countries either implicitly or explicitly informed by behavioural insights (BIs). It reviews institutional developments around the application for behavioural insights for policy and puts forward a comparative framework (PRECIS) describing behavioural insights teams with six key features. The report reaches four main conclusions: i) in terms of capacity-building, there is significant dynamism and growing appetite to apply BIs to policy-making; ii) links between policy-making and academy communities can be strengthened and analysing large datasets offers great potential; iii) systematic application of BIs throughout the policy cycle can advance evidence-based policy-making; iv) there is a need for more research on the long-term impacts of policy interventions.JRC.DDG.02-Foresight and Behavioural Insight

IDENTIFICAÇÃO E CLASSIFICAÇÃO DE EPISÓDIOS DE CHUVA EXTREMA NO DISTRITO FEDERAL – PERÍODO 1990-2019

The aim of this article is to analyze the occurrence of extreme rainfall episodes in the historical series of rainfall for the period 1990-2019 in the Federal District. The threshold of 0.1 mm/daily was used to identify rain episodes, which were classified into the following classes: 0.1 to 2.5 mm – drizzle; 5 to 10.0 mm – light rain; 10.0 to 15.0 mm – moderate rain; 15.0 to 25.0 mm – relatively heavy rain; 25.0 to 50.0 mm – heavy rain; 50.0 mm – extreme rain. The 99th Percentile methodology was also applied to identify the most extreme rain episodes in the series. The total value of 3,988 cases of rainfall was obtained, making it possible to identify 27 cases of extreme rainfall events in the DF. Of this total, 10 cases were recorded in the 1990s, in the 2000s there were 8 cases and from 2010 there were 9 cases. The data and information generated in this article make it possible to provide reliable references for reflection and action by government agencies, civil society and autonomous organizations about possible disasters caused by heavy rains in the DF.O objetivo deste artigo é analisar a ocorrência de episódios de chuvas extremas na série histórica de precipitação pluvial referente ao período 1990-2019 no Distrito Federal.

Imagens e imaginários sobre Brasília turística : da Capital Nacional ao patrimônio-territorial

Brasilia, symbol of modernity in Brazil, was designed by means of speech and of the political ideologies of Brazil. Considered utopian, the new Capital has used the resources to symbolic launch your image and ensure the acceptance of national population. The project for the construction of Brasilia is relatively old, because the idea of transferring the Capital to the center of the country came from the period in which Brazil was still a portuguese colony. Brasília was inaugurated in the 1960s and their historical context of exception made it on the list of Historic Patrimony of the Humanity. However, its territorial dynamics turned Brasilia a city policy in relation to the social problems it presents. Currently, the Federal District has 31 Administrative Regions, many of these cities were created in the context of the construction of Brasilia, but this memory is constantly overlooked, projecting only the image of Brasilia as the Pilot Plan. Thus, this study aims to analyze Brasilia and its tourist potential from your estate planning.Brasília, símbolo da modernidade brasileira, foi projetada por meio do discurso e das ideologias políticas do Brasil. Considerada utópica, a nova Capital utilizou dos recursos simbólicos para lançar sua imagem e garantir a aceitação da população nacional. O projeto de construção de Brasília é algo relativamente antigo, pois a ideia de transferir a Capital para o centro do país vem desde o período em que o Brasil ainda era uma colônia portuguesa. Brasília foi inaugurada na década de 1960 e seu contexto histórico excepcional fez com que fosse inscrita na lista de Patrimônio Histórico da Humanidade. Entretanto, sua dinâmica territorial acabou tornando Brasília uma cidade comum em relação aos problemas sociais que apresenta. Atualmente o Distrito Federal possui 31 Regiões Administrativas, muitas dessas cidades foram criadas no contexto da construção de Brasília, porém essa memória é constantemente negligenciada, projetando apenas a imagem de Brasília como o Plano Piloto. Assim, este trabalho pretende analisar Brasília e seu potencial turístico a partir de seu patrimônio-territorial

Isolamento e caracterização de fibroblastos gengivais positivos para fosfatase alcalina de pacientes portadores de periodontite crônica e hiperplasia gengival medicamentosa

PURPOSE: To investigate the expression of alkaline phosphatase (ALP) activity in gingival fibroblasts from individuals with chronic periodontitis (CP) and drug-induced gingival hyperplasia (DGH) induced by diphenylhydantoin. METHODS: Gingival fragments were obtained from 13 patients (8 women and 5 men, from 22 to 74 years of age), with 4 fragments from clinically normal gingiva (NG), 5 from biopsy of periodontal pockets with CP, and 4 from DGH induced by diphenylhydantoin. Using an enzymatic digestion procedure, gingival cell suspensions containing ALP-positive fibroblasts were prepared without affecting ALP activity. Cytochemistry and histochemistry analyses were performed. RESULTS: Fibroblasts from NG presented low levels of ALP when compared to CP and DGH, which showed elevated and intermediate levels of ALP, respectively. Little cell proliferation was observed for fibroblasts from CP and DGH as compared to NG. However, the quantity of cells recovered from the subcultures was similar to the quantity recovered from the initial cell culture for the three sources. CONCLUSION: The expression of ALP is increased in CP and DGH, and fibroblasts in CP and DGH show low proliferation. This suggests that periodontal inflammation and diphenylhydantoin may influence ALP expression and human gingival fibroblast expansion. Other studies are necessary to better assess the importance of ALP in the development and progression of CP and DGH.OBJETIVO: Investigar a expressão da atividade de fosfatase alcalina (ALP) em fibroblastos gengivais de sujeitos com periodontite crônica (PC) e hiperplasia gengival medicamentosa (HGM) induzida por difenilhidantoína. METODOLOGIA: Os fragmentos gengivais foram obtidos de 13 pacientes (8 mulheres e 5 homens, 22 a 74 anos), sendo 4 fragmentos procedentes de gengiva clinicamente normal (GN), 5 de biópsias de bolsas periodontais com PC e 4 de HGM induzida pela difenilhidantoína. Através de digestão enzimática, suspensões de células gengivais foram preparadas contendo fibroblastos ALP-positivos sem afetar a atividade da enzima ALP. Análises citoquímica e histoquímica foram realizadas. RESULTADOS: Fibroblastos de GN apresentaram fraca positividade para ALP quando comparados com PC e HGM. PC e HGM exibiram níveis elevados e intermediários, respectivamente, de ALP. Observou-se menor proliferação celular na cultura de células em PC e HGM que em GN. Entretanto, a quantidade de células recuperadas das sub-culturas foi similar à quantidade recuperada na cultura inicial para as três linhagens. CONCLUSÕES: A expressão de ALP na PC e na HGM encontra-se aumentada e ocorre baixa proliferação de fibroblastos na PC e na HGM. Isto sugere que a inflamação periodontal e a difenilhidantoína podem influenciar a expressão de ALP e a multiplicação de fibroblastos gengivais humanos. Outros estudos são necessários para melhor avaliar a importância de ALP no desenvolvimento e na progressão de PC e HGM.545

Anxiolytic and Anticonvulsant Effects on Mice of Flavonoids, Linalool, and α-Tocopherol Presents in the Extract of Leaves of Cissus sicyoides L. (Vitaceae)

The aim of the present study is to demonstrate the anxiolytic and anticonvulsant effects of a hydroalcoholic extract obtained from the aerial parts of Cissus sicyoides L. (CS) (Vitaceae) on male and female mice using several behavioral assays. Groups of males and females treated via intraperitoneal (IP) with doses of 300, 600, and 1000 mg/kg of the extract showed significant action in the elevated plus-maze (EPM), time spent in the open arms, and number of entries in the open arms. The board-hole test also showed a significant increase in the time spent in head-dipping and in marble-burying test of the number of marbles buried. The same treatment increased the duration of sleeping time induced by sodium pentobarbital and also showed a significant increase in protection against pentylenotetrazole-induced convulsions. These results indicate an anxiolytic and anticonvulsant-like action from C. sicyoides L. extract on mice, probably due to the action of flavonoid(s), Linalool, and α-tocopherol present in the C. sicyoides leaves

THE REDUCED GAMES IN FUTSAL AND ITS INFLUENCE IN TACTICAL AND TECHNICAL ACTIONS IN ATHLETES UNDER-13

Currently in Brazil, futsal is one of the most practiced and growing modalities, due to the passion of the Brazilian by the modality, the increase of blocks in the urban areas and the ease to its practice (because it is a sport that uses a reduced space and few players). Therefore, the objective of this study was to verify how adapted games (reduced games) can influence some tactical and technical factors of the modality (ball possession, passes and finalizations). Ten male subjects aged 12 to 13 years participated in the study, who underwent a training periodization composed of 16 sessions based on reduced games only. Before and after the training, games (Game 1 and Game 2) were carried out, which were filmed and were used for scout analysis. Descriptive statistics were used. It was observed after the period of the training sessions increase in the time of possession of total ball during the match, time of possession of defensive ball, certain passes, certain finalizations, and goals scored in favor. In contrast, there was a reduction in offensive ball possession time, number of wrong passes, total number of finalizations and number of wrong finishes. It is observed that the training with reduced games can be effective for the improvement of several technical and tactical components in collective sports games, especially in futsal. As this research approached the descriptive analysis component, we cannot affirm that there were significant changes from Game 1 to Game 2, however, in a simple analysis, small beneficial modifications were observed.  Article visualizations
