Bologna process, higher education and a few considerations about the New University

O presente artigo analisa o que se convencionou chamar de Processo de Bolonha, isto é, a produção de uma “política pública de um meta-Estado para um meta-campo universitário”, constituindo-se em uma política educacional supranacional, comum aos estados-membros da União Européia, com vista à construção de um “espaço europeu de educação superior”. O processo político e de reformas institucionais, realizado por cada governo nacional, conduzirá ao estabelecimento efetivo do novo sistema europeu de educação superior até 2010, incluindo atualmente 45 países – todos os da UE e outros 18 países europeus não pertencentes a ela. Nesse sentido, por se tratar de um vastíssimo número de “subsistemas nacionais” e de instituições educativas, atribui-se um grande protagonismo às questões relativas à “garantia de qualidade”. Analisam-se, igualmente, as recentes transformações na educação superior no Brasil, em que o projeto da chamada “Universidade Nova” e o Programa de Apoio a Planos de Reestruturação e Expansão das Universidades Federais (REUNI) constituem-se nas manifestações mais claras do reordenamento desse nível de ensino (seguindo os parâmetros de Bolonha), que já experimentara grandes transformações nos governos de Fernando Henrique Cardoso (1995-2002) e teve prosseguimento nos governos de Luiz Inácio Lula da Silva (2003-2006; 2007), embora com distintos matizes.This article analyzes what is conventionally known as the Bologna Process, or the making of a “public policy of a meta-State for a University meta-field” that corresponds to a supranational educational policy for all the European Union membership States, with the goal of building a “European higher education space.” The political process and the institutional reforms of each national government intends to establish the new European higher education system until 2010, with 45 countries – the number reflects current developments, including the EU membership States and 18 non-EU countries. Given the high quantity and the myriads of “national subsystems” and educational institutions involved, “quality assurance” becomes a major task in this process. We analyze, in the same way, the recent higher education changes in Brazil, where the so-called “New University” project and the Program of Support for the Restructuring and Expansion of Brazilian Federal Universities (REUNI, in Portuguese) are the clearest expressions of the reshaping of the higher education system (in accordance with the Bologna standards) after the dramatic changes made by Fernando Henrique Cardoso´s government (1995-2002) and continued by Luiz Inácio Lula da Silva´s government (2003-2006; 2007), despite some differences between both administrations

Nutritional value and kinetics of in vitro fermentation of spineless cactus of the genus Nopalea in different phenological phases

Abstract The objective was to evaluate the chemical composition and in vitro fermentation of spineless cactus of the genus Nopalea, F-21 (Nopalea cochenillifera Dyck), IPA-Sertânia (Nopalea cochenillifera Dyck) and Miúda (Nopalea cochenillifera Salm Dyck), in different phenophases. There was no effect (P < 0.05) of the phenological phases of spineless cactus on DM, ash, OM, EE, and CP. Varieties F-21 and Miúda presented higher values of DM and OM, whereas the CP was higher for IPA-Sertânia. The contents of NDF, ADF, and ADL, as well as the fractions of carbohydrates B2 and C were higher in the mature stage, irrespective of the variety. The Miúda variety showed higher levels of NFC and fractions A + B1 and the lower levels of pectin compared to the F-21 and IPA-Sertânia varieties, but not differ of TC to F-21. The volume of gas produced via the degradation of NFC was higher for young phenological phases. The young and intermediate stages showed a higher in vitro digestibility of DM. Based on the results, varieties IPA-Sertânia and Miúda have a high potential for use in animal feed because of their high nutritional quality. Mature cladodes showed a higher fibrous fraction and lower digestibility in all varieties

QMix® irrigant reduces lipopolysacharide (LPS) levels in an in vitro model

AbstractThe presence of endotoxin inside the root canal has been associated with periapical inflammation, bone resorption and symptomatic conditions.Objectives To determine, in vitro, the effect of QMix® and other three root canal irrigants in reducing the endotoxin content in root canals.Material and Methods Root canals of single-rooted teeth were prepared. Samples were detoxified with Co-60 irradiation and inoculated with E. coli LPS (24 h, at 37°C). After that period, samples were divided into 4 groups, according to the irrigation solution tested: QMix®, 17% EDTA, 2% chlorhexidine solution (CHX), and 3% sodium hypochlorite (NaOCl). LPS quantification was determined by Limulus Amebocyte Lysate (LAL) assay. The initial counting of endotoxins for all samples, and the determination of LPS levels in non-contaminated teeth and in contaminated teeth exposed only to non-pyrogenic water, were used as controls.Results QMix® reduced LPS levels, with a median value of 1.11 endotoxins units (EU)/mL (p<0.001). NaOCl (25.50 EU/mL), chlorhexidine (44.10 EU/mL) and positive control group (26.80 EU/mL) samples had similar results. Higher levels were found with EDTA (176.00 EU/mL) when compared to positive control (p<0.001). There was no significant difference among EDTA, NaOCl and CHX groups. Negative control group (0.005 EU/mL) had statistically significant lower levels of endotoxins when compared to all test groups (p<0.001).Conclusion QMix® decreased LPS levels when compared to the other groups (p<0.001). 3% NaOCl, 2% CHX and 17% EDTA were not able to significantly reduce the root canal endotoxins load

A viagem de José Gonçalves da Fonseca e a cartografia do rio Madeira (1749-1752)

This article looks into the voyage of the "royal escort", a reconnaissance expedition sent from Belém do Pará in 1749 to explore the fluvial communication between the state of Maranhão and Grão-Pará and the captaincy of Mato Grosso down the courses of the Rivers Madeira, Mamoré and Guaporé, and its impact on the cartographic representation of this region. The considerable differences between the map drawn by José Gonçalves da Fonseca and the map of the boundaries of Brazil prepared for the negotiations with the Spanish Crown astonished the Portuguese politicians in charge of the matter before they set out to demarcate the South American territories according to the Treaty of Madrid signed by Portugal and Spain in 1750

Genotype and phenotype landscape of MEN2 in 554 medullary thyroid cancer patients: the BrasMEN study

Multiple endocrine neoplasia type 2 (MEN2) is an autosomal dominant genetic disease caused by RET gene germline mutations that is characterized by medullary thyroid carcinoma (MTC) associated with other endocrine tumors. Several reports have demonstrated that the RET mutation profile may vary according to the geographical area. In this study, we collected clinical and molecular data from 554 patients with surgically confirmed MTC from 176 families with MEN2 in 18 different Brazilian centers to compare the type and prevalence of RET mutations with those from other countries. The most frequent mutations, classified by the number of families affected, occur in codon 634, exon 11 (76 families), followed by codon 918, exon 16 (34 families: 26 with M918T and 8 with M918V) and codon 804, exon 14 (22 families: 15 with V804M and 7 with V804L). When compared with other major published series from Europe, there are several similarities and some differences. While the mutations in codons C618, C620, C630, E768 and S891 present a similar prevalence, some mutations have a lower prevalence in Brazil, and others are found mainly in Brazil (G533C and M918V). These results reflect the singular proportion of European, Amerindian and African ancestries in the Brazilian mosaic genome

Consistent patterns of common species across tropical tree communities

Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1,2,3,4,5,6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth’s 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world’s most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.Publisher PDFPeer reviewe

Pervasive gaps in Amazonian ecological research

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
