LERCAFÉ: novo teste para estimar o potencial germinativo de sementes de cafeeiro (Coffea arabica L.)

Com o objetivo de utilizar o hipoclorito de sódio no desenvolvimento de novo teste para avaliar rapidamente a qualidade das sementes de cafeeiro, por meio da estimativa da germinação, o presente trabalho foi realizado com quatro lotes de sementes de cafeeiro (Coffea arabica L.), cultivar IAC Catuaí 44 e quatro lotes da cultivar Rubi. A porcentagem de germinação das sementes foi estimada pelo teste desenvolvido, denominado LERCAFÉ, em duas metodologias. No método 1, as sementes tiveram seu pergaminho removido manualmente e foram imersas em solução de hipoclorito de sódio a 2,5%, por 3 horas. Posteriormente, as sementes foram lavadas e avaliadas visualmente. No método 2, as sementes com pergaminho foram imersas em hipoclorito de sódio a 5,0% por seis horas, lavadas e imersas em água destilada por 40 min e avaliadas. Na avaliação visual das sementes, foram consideradas não germináveis as sementes que apresentavam formação de coloração esverdeada na região embrionária e que não apresentavam embrião visível; a qualidade dos lotes também foi caracterizada pelo teste de germinação. Os dois métodos do teste apresentam alta correlação com o teste de germinação. Conclui-se que o uso do teste LERCAFÉ na avaliação rápida das sementes de café é de baixo custo, de fácil execução e interpretação, permitindo estimar com precisão e rapidez o potencial de germinação das sementes de cafeeiro, além de apresentar características não destrutivas, favorecendo a avaliação das plântulas provenientes das sementes testadas.

O social no governo Lula: a construção de um novo populismo em tempos de aplicação de uma agenda neoliberal

The purpose of this paper is to discuss the main characteristics of new Lula's government support. The paper's hypothesis concentrates in the idea of starting a different political approach, "a new populism". The paper argues that Lula's government to keep in power, beyond of going on with the neoliberal project - unfinished in the last years of FHC government -, needs to build up a solid and trustful political support, which is being done by implementing income transfer programs directed to poor people and the ones with less organization experience. This paper also calls the attention to Lula's government nature, in order to clarify the difficulties which should be dealt and the tasks to be developed in building up a political party that defends workers emancipation and Brazilians exploited.

Por que novo-desenvolvimentismo?

This paper develops some general guidelines that should take part of a new view of development to Brazil, in opposition to the neoliberal project. This alternative, that is called "new developmentalism", should include sustained economic growth with social equity.

A Argentina depois da conversibilidade: um caso de novo-desenvolvimentismo?

This paper analyses the economic recovery in post-Convertibility Argentina. We try to identify if there are evidences to support the suggestion that Argentina could be an example of the so-called "new developmentalism".

Notas críticas sobre a macroeconomia novo-Keynesiana

This article shows that, in spite of its great steps towards reality, new-Keynesian macroeconomics seems to be a non-systematic construction with problems originated from "ad hoc" hypothesis required to explain the non neutrality of money and the existence of disequilibria in the short run. In particular, it seems that prices and wages rigidities stand in sandy bases and that the derivation of the IS and LM curves from neoclassical fundamentals is problematic. Even disregarding the apparent difficulties of the neoclassical theory of value and distribution, the new-Keynesian connections between interest rate, money, and output do not seem fully consistent.

Persistência inflacionária e curva de Phillips novo-keynesiana para o Brasil

Inflation persistence and new Keynesian Phillips curves for Brazil. In this paper is shown that sustainable inflation persistence has theoretical support not only due price indexation, but also because of micro-foundations based on assumptions of Simon's bounded rationality and because of persistent mark-up shocks. the new keynesian phillips curve, estimated for brazil for the period 2000/2008, and the partial coefficients of determination for moving sub-periods of 36 months identifies inflation persistence as the main determinant of inflation, with the capacity gap presenting larger importance only in the end of the sample period. Inflation persistence requires harder monetary policy when neither accommodation is acceptable nor complementary policies in order to reduce it, such as the minimization of indexation mechanisms and control of the market power, are adopted.

Da economia política à política econômica: o novo-desenvolvimentismo e o governo Lula

From political economy to economic policy: The neo-developmentalism and the Lula administration. This article critically reviews the design of neo-developmentalist economic policies in Brazil, in the first half of the last decade, and their relationship with the economic policies of the Lula administration after 2006. Paradoxically, the neo-developmentalist policies were implemented jointly with the main (neoliberal) macroeconomic policies which had been introduced earlier. The article reviews the relevant literature, and examines the contradictory nature of this 'inflection' of economic policy. So far, this combination of policies has achieved an unquestionable - though provisional - success, despite the persistence of the structural macroeconomic problems due to the continuity of the neoliberal policies.

Teoria das finanças funcionais e o papel da política fiscal: uma crítica pós-keynesiana ao novo consenso macroeconômico

Theory of functional finance and the role of fiscal policy: A post-keynesian critique to the new consensus macroeconomics. This paper presents the critical approaches and elaborates the arguments that oppose those of the New Consensus Macroeconomics regarding the conduct of fiscal policy. Those criticisms and arguments are based in the post-Keynesian thought and the theory of Functional Finance. The theory of Functional Finance is an extension of the Keynesian approach, particularly with regard to discussions on public finances. As supports the theory of Functional Finance, the objectives to be pursued by fiscal policy should suggest the improvement of social welfare as a whole, i.e., the performance of inflation, employment and output should be taken into account by policymakers.

Gênese e agenda do novo desenvolvimentismo brasileiro

The debate regarding Brazil's development model returned again to the public arena in the first decade of 21st century after two decades of orthodox economic policies which encouraged non-developed countries to adopt liberal economic policies as their preferred growth strategies. As Brazil achieved neither economic stability nor development, the discussion of new development strategies returned as a popular research topic. It is in this context that a new development theory - New Developmentalism - emerges. The objective of this article is to review the origins of this debate and the main propositions defended by the group aiming to implement a new development model policy in the country. The main conclusions are that this group has had an important contribution in maintaining the development debate in the public agenda as well as proposing a new theoretical approach called "structuralist macroeconomic development".

Desenvolvimentismo e novo-desenvolvimentismo: raízes teóricas e precisões conceituais

This paper starts from the conceptualism of New Developmentalism which was proposed by its formulators and their criticism of the "old" developmentalism in order to compare both. It is elaborate in both theoretical and historical levels. In the former, it explores the theoretical streams that contributed to the formulation of economic policies that designated the Latin American developmentalism. In the latter, it focuses on the economic policy of the Brazilian import-substitution industrialization and advocates the impropriety of associating it to the irresponsibility in the management of the foreign exchange, fiscal and monetary policies, as the proposers of New Developmentalism assert. Finally, in a third stage, it resumes the propositions of the New Developmentalism and debates the pertinence of some of its policy propositions based upon theoretical considerations and the Brazilian experience which were mentioned in the previous stages.

Crescimento clássico e crescimento retardatário: um novo enfoque para políticas de desenvolvimento

RESUMO O artigo defende a tese de que, diferentemente do que acontece nos países desenvolvidos, em que o crescimento depende dos níveis de poupanças e de inovações tecnológicas, nos países subdesenvolvidos o crescimento está condicionado à disponibilidade de mercado. Em termos de política econômica, isso significa que nos desenvolvidos o esforço deve ser no sentido da criação de poupanças e inovações tecnológicas de nível adequado, enquanto nos subdesenvolvidos o importante é garantir mercado do dinamismo e dimensões necessários à eliminação de seu atraso econômico. O não reconhecimento dessa diferença, resultante de a Economia do Desenvolvimento não ter proposto modelo específico para o crescimento retardatário, tem levado a sérios erros nas políticas de desenvolvimento.

Por um Novo Estatuto Temático da Carta a D’Alembert

RESUMO:A réplica rousseauniana a d’Alembert, autor do verbete Genebra da Enciclopédia, foi batizada como Carta sobre os espetáculos, em respeito ao tema nela tratado após os dez primeiros parágrafos, os quais abordam explicitamente o tema da intolerância religiosa. Contudo, o presente artigo apresenta, sob a perspectiva de uma moral da tolerância que não se resume às questões religiosas, a defesa de que a Carta a d’Alembert é uma integral e avançada Carta sobre a Tolerância, por contemplar, além do discurso iluminista de recusa à inquirição ou inspeção da fé alheia em matéria de religião, uma atualizada recusa multiculturalista ao etnocentrismo.

De novo transcriptome assembly and annotation of the isopod Idotea balthica

The Baltic Sea is a unique environment that contains unique genetic populations. In order to study these populations on a genetic level basic molecular research is needed. The aim of this thesis was to provide a basic genetic resource for population genomic studies by de novo assembling a transcriptome for the Baltic Sea isopod Idotea balthica. RNA was extracted from a whole single adult male isopod and sequenced using Illumina (125bp PE) RNA-Seq. The reads were preprocessed using FASTQC for quality control, TRIMMOMATIC for trimming, and RCORRECTOR for error correction. The preprocessed reads were then assembled with TRINITY, a de Bruijn graph-based assembler, using different k-mer sizes. The different assemblies were combined and clustered using CD-HIT. The assemblies were evaluated using TRANSRATE for quality and filtering, BUSCO for completeness, and TRANSDECODER for annotation potential. The 25-mer assembly was annotated using PANNZER (protein annotation with z-score) and BLASTX. The 25-mer assembly represents the best first draft assembly since it contains the most information. However, this assembly shows high levels of polymorphism, which currently cannot be differentiated as paralogs or allelic variants. Furthermore, this assembly is incomplete, which could be improved by sampling additional developmental stages.
