Balance-of-payments-constrained growth in Brazil: 1951-2008

The aim of this study is to determine whether Brazil's economic growth has been constrained by the balance of payments in the long run. The question underpinning the analysis can be expressed as follows: Was economic growth in the period 1951-2008 constrained by the balance of payments? To answer this question, the study employs the externally constrained growth methodology developed by Lima and Carvalho (2009), among others. The main statistical method used is vector error correction. The conclusion is that the rate of economic growth in Brazil was restricted by the external sector in the period concerned, validating the theory of balance-of-payments growth constraint with regard to the economic history of Brazil.

Êxodo: a mulher no processo de partir

Este relatório tem como função mostrar e descrever as fases de produção do trabalho de conclusão de curso de Rádio e Televisão denominado “Êxodo, a mulher no processo de partir” que aborda o mundo feminino focando na imagem da mulher vinculada pela religião católica e pelos meios de comunicação, e visando mostrar a imagem real de como elas são, o que sentem, suas dores e superações. Fazendo, desse modo, um contrapeso entre o real e o imaginário. Os produtos deste trabalho são um vídeo documentário e um livro dos quais em sua liguagem de narrativa trazem a mulher não como a problemática, mas sim a sociedade paternalista em que ela se encontra dificultando sua verdadeira manifestação, sua natureza e limitando suas perspectivas que acabam por torná-las generalizadas, marginalizadas e inferiorizadas em uma cultura machista e sexista que reflete na mídia atingindo a mulher diretamente e causando a ela sucessivas dificuldades, alardes e submissão, tal como o desgaste emocional no dia a dia que nem sempre tem explicação

Aspectos reprodutivos de Harttia carvalhoi Miranda Ribeiro, 1939, um pequeno loricariídeo de riachos do leste da serra da Mantiqueira, SP, Brasil

O objetivo deste trabalho foi apresentar os aspectos reprodutivos de Harttia carvalhoi, Miranda Ribeiro, 1939, um pequeno loricariídeo cuja distribuição é restrita a área de drenagem do rio Paraíba do Sul. Um total de 110 exemplares de H. carvalhoi foi obtido. O período reprodutivo acontece desde setembro até fevereiro. O tipo de desova foi identificado como total e a taxa de fecundidade variou de 16 a 106 ovócitos. Este tipo de estudo é importante, visto que fecundidade é uma característica específica e é uma adaptação às condições do ciclo de vida, variando com o crescimento, densidade populacional, alimentos disponíveis e taxa de mortalidade. Também foi enfatizada a importância deste estudo, pois não há estudos prévios sobre a reprodução desta espécie

Fungos fitopatógenos associados às formigas cortadeiras (Formicidae: Tribo Attini)

The ants of genus Atta belong to the Attine tribe (order Hymenoptera, family Formicidae, subfamily Myrmicinae) and are commonly known as leaf-cutting ants for having the habit of cutting several vegetable species used as substrate for growing mutualistic fungus (Agaricales: Lepiotaceae). Recent studies showed that, in addition to that, other fungi may occur in the nests in a dorment state or participate in the functioning dynamic of this symbiosis. Researches related to surveys of fungus biodiversity in nests of different Atta species have found important phytopathogenic representatives. In Brazil, studies about integrated management of plagues, developed by Embrapa Meio Ambiente (Embrapa Environment), point out the need of higher investments in projects that involve the phytopathogenic transmission by insects in order to reduce costs to control them or minimize environmental impact. The purpose of this study was to broaden the knowledge about the ecology of these fungi, isolating and identifying species associated with Attine tribe ants, thus understanding the scope of pathogenic and phytopathogenic species spread by these ants. For that reason, gynes were collected from Atta laevigata and Atta capiguara anthills located at Unesp Botucatu (São Paulo, Brazil) campus. In order to isolate the fungus, the mineral oil floating technique was used. The identification of the isolated fungi was done based on microscopic and molecular characteristics using DNA ribosomal sequencing. The most highly abundant genera found so far were: Cladosporium, Exophiala, Penicillium, Acremonium, Phialophora and Teratosphaeria. Representatives of the genera Exophiala, Phialophora and Cladosporium may be human pathogens, whereas Teratosphaeria and Penicillium are related to diseases in Eucalyptus and citric fruits, respectively. The results show that these ants may host important fungal species besides the ones already... (Complete abstract click electronic access below)

Dimorfismo sexual em Dasypops schirchi (Miranda-Ribeiro, 1924): aspectos morfológicos

Amphibians exhibit great morphological plasticity of habitat and life history. This heterogeneity contributes to the frequency of occurrence and diversity of sexual dimorphism (shape or size) is large. Dasypops schirchi is a species belonging to the subfamily and family Gastrophryninae Microhylidae and this endemic and endangered. Generally, very little is known about D. schirchi, much in part to its habit of living and cryptic small geographical distribution. In order to detect and characterize elements sexually dimorphic in this species was a survey of specimens of D. schirchi in major national zoological collections. We analyzed 16 morphometric variables were also searched and secondary sexual characters non-morphometric. Statistical analysis of the morphometric data, the results showed a clear distinction between males and females of D. schirchi, secondary sexual characters nonmorphometric were also found

O Mestre, de Ana Hatherly: uma insólita aprendizagem

O mestre (1963), written by the Portuguese author Ana Hatherly, continues to challenge our reading due to its disturbing nature. The text is not only connected to and transcends the emerging modernity of the Portuguese poetic avant- -garde experimental proposals of the period, presenting itself as a permanent intriguing text. This paper examines the narrative procedures put into action in order to destabilize the relationship I – the Other (master and apprentice), multiform agents, producers of metamorphosis and disturbing actions. The female narrator addresses love, truth, knowledge and power in an uncommon way and transforms the narrative into a magic practice, with surprising effects.

Corpo lavrado: a poesia telúrica de Ana Paula Tavares

In this paper we analyze how the symbols of land and woman are articulated in the lyric from Ana Paula Tavares. Such motifs, applicants at O lago da lua (1999), will take on a structuring in the poetic universe from this Angolan writer, because architect his being in the world at an existential level and political. Paula Tavares gives her voice to express, with defiance and tenderness, the bitter cry of women prisoners in their own silence. The symbiosis between land and woman works as formative and empowering element of identity

Available nitrogen and responses to nitrogen fertilizer in brazilian eucalypt plantations on soils of contrasting texture

Eucalyptus plantations have seldom responded to N fertilization in tropical and subtropical regions of Brazil. This implies that rates of N mineralization have been adequate to supply tree needs. However, subsequent crop rotations with low N fertilization may result in declining concentrations of organic and potentially mineralizable N (N-0), and consequent loss of wood productivity. This study investigated (a) in situ N mineralization and N-0 in soils of eucalypt plantations in Sao Paulo state, Brazil; (b) tree growth responses to N fertilizer applied 6-18 months after planting; and (c) the relationships between N-0,N- other soil attributes and tree growth. We established eleven N fertilizer trials (maximum 240 kg ha(-1) of N) in E. grandis and E. grandis x urophylla plantations. The soil types at most sites were Oxisols and Quartzipsamments, with a range of organic matter (18 to 55 g kg(-1)) and clay contents (8% to 67%) in the 0-20 cm layer. Concentrations of N-0 were measured using anaerobic incubation on soil samples collected every three months (different seasons). The samples collected in spring and summer had N-0 140-400 kg ha(-1) (10%-19% total soil N), which were best correlated with soil texture and organic matter content. Rates of in situ net N mineralization (0-20 cm) ranged from 100 to 200 kg ha(-1) year(-1) and were not correlated with clay, total N, or N-0. These high N mineralization rates resulted in a low response to N fertilizer application during the early ages of stand growth, which were highest on sandy soils. At the end of the crop rotation, the response to N fertilizer was negligible and non-significant at all sites.
