ELEMENTOS DA OBRA FREIREANA E DA TEOLOGIA DA LIBERTAÇÃO NAS DÉCADAS DE 1950 A 1970: UMA ANÁLISE COMBINADA DE SUA GÊNESE E IDENTIDADE

A presente pesquisa se propõe a analisar o contexto histórico, político, social, econômico e ideológico em que surge a pedagogia crítica de Paulo Freire e posteriormente a Teologia da Libertação, visando encontrar influências deste peculiar contexto na gênese do pensamento freireano e nas concepções dos te��logos Rubem Alves e Gustavo Gutiérrez, que foram os primeiros publicar obras sobre Teologia da Libertação, corrente teológica considerada genuinamente latino-americana. Ainda procura observar em que medida as concepções pedagógicas de Freire podem ter sido acolhidas pelos te��logos Alves e Gutiérrez em suas obras aqui analisadas. Em ambos os pensamentos encontramos a visão de valorização do ser humano e de uma práxis que busca sua libertação de sistemas opressores. Tanto em Paulo Freire como nos fundamentos desta corrente teológica se apresentam princípios humanistas e elementos da tradição cristã. A partir da ferramenta metodológica de análise do materialismo histórico dialético marxista, procura identificar temas comuns que são abordados pelos autores em suas obras surgidas entre as décadas de 1950 a 1970, detendo-se ao estudo de alguns temas subjacentes a esse contexto histórico, a saber: práxis, história, humanismo e libertação.

Fashions and fads in finance: contingent emulation and the political economy of sovereign wealth fund creation. IHS Political Science Series No. 131, July 2012

Sovereign wealth funds (SWFs), government-owned or managed investment vehicles, have proliferated at a remarkable rate over the past decade, even as political controversy has surrounded them. Why? The extant literature depicts the process of SWF creation as driven by functional imperatives associated with “excess” revenue and reserves accumulated from commodity booms and large current account surpluses. I argue that SWF creation also reflects in large part a process of contingent emulation in which first this policy has been constructed as appropriate for countries with given characteristics, and then when countries took on these characteristics, they followed their peers. Put simply, fashions and fads in finance matter for policy diffusion. I assess this argument using a new dataset on SWF creation that covers nearly 80 countries from 1984 to 2007. The results suggest peer-based contingent emulation has been a crucial factor shaping the decision of many countries to create a SWF, especially among fuel exporters.

Dimethylsulphide and halocarbon concentrations taken from 10m integrated samples during the 2012 KOSMOS Finland Mesocosm experiment

The Baltic Sea is a unique environment as the largest body of brackish water in the world. Acidification of the surface oceans due to absorption of anthropogenic CO2 emissions is an additional stressor facing the pelagic community of the already challenging Baltic Sea. To investigate its impact on trace gas biogeochemistry, a large-scale mesocosm experiment was performed off Tvärminne Research Station, Finland in summer 2012. During the second half of the experiment, dimethylsulphide (DMS) concentrations in the highest fCO2 mesocosms (1075-1333 µatm) were 34 % lower than at ambient CO2 (350 µatm). However the net production (as measured by concentration change) of seven halocarbons analysed was not significantly affected by even the highest CO2 levels after 5 weeks exposure. Methyl iodide (CH3I) and diiodomethane (CH2I2) showed 15 % and 57 % increases in mean mesocosm concentration (3.8 ± 0.6 pmol L-1 increasing to 4.3 ± 0.4 pmol L-1 and 87.4 ± 14.9 pmol L-1 increasing to 134.4 ± 24.1 pmol L-1 respectively) during Phase II of the experiment, which were unrelated to CO2 and corresponded to 30 % lower Chl-? concentrations compared to Phase I. No other iodocarbons increased or showed a peak, with mean chloroiodomethane (CH2ClI) concentrations measured at 5.3 (± 0.9) pmol L-1 and iodoethane (C2H5I) at 0.5 (± 0.1) pmol L-1. Of the concentrations of bromoform (CHBr3; mean 88.1 ± 13.2 pmol L-1), dibromomethane (CH2Br2; mean 5.3 ± 0.8 pmol L-1) and dibromochloromethane (CHBr2Cl, mean 3.0 ± 0.5 pmol L-1), only CH2Br2 showed a decrease of 17 % between Phases I and II, with CHBr3 and CHBr2Cl showing similar mean concentrations in both Phases. Outside the mesocosms, an upwelling event was responsible for bringing colder, high CO2, low pH water to the surface starting on day t16 of the experiment; this variable CO2 system with frequent upwelling events implies the community of the Baltic Sea is acclimated to regular significant declines in pH caused by up to 800 µatm fCO2. After this upwelling, DMS concentrations declined, but halocarbon concentrations remained similar or increased compared to measurements prior to the change in conditions. Based on our findings, with future acidification of Baltic Sea waters, biogenic halocarbon emissions are likely to remain at similar values to today, however emissions of biogenic sulphur could significantly decrease from this region.

KOSMOS Finland 2012 mesocosm study: primary production and respiration

Anthropogenic carbon dioxide (CO2) emissions are reducing the pH in the world's oceans. The plankton community is a key component driving biogeochemical fluxes, and the effect of increased CO2 on plankton is critical for understanding the ramifications of ocean acidification on global carbon fluxes. We determined the plankton community composition and measured primary production, respiration rates and carbon export (defined here as carbon sinking out of a shallow, coastal area) during an ocean acidification experiment. Mesocosms (~ 55 m3) were set up in the Baltic Sea with a gradient of CO2 levels initially ranging from ambient (~ 240 µatm), used as control, to high CO2 (up to ~ 1330 µatm). The phytoplankton community was dominated by dinoflagellates, diatoms, cyanobacteria and chlorophytes, and the zooplankton community by protozoans, heterotrophic dinoflagellates and cladocerans. The plankton community composition was relatively homogenous between treatments. Community respiration rates were lower at high CO2 levels. The carbon-normalized respiration was approximately 40 % lower in the high CO2 environment compared with the controls during the latter phase of the experiment. We did not, however, detect any effect of increased CO2 on primary production. This could be due to measurement uncertainty, as the measured total particular carbon (TPC) and combined results presented in this special issue suggest that the reduced respiration rate translated into higher net carbon fixation. The percent carbon derived from microscopy counts (both phyto- and zooplankton), of the measured total particular carbon (TPC) decreased from ~ 26 % at t0 to ~ 8 % at t31, probably driven by a shift towards smaller plankton (< 4 µm) not enumerated by microscopy. Our results suggest that reduced respiration lead to increased net carbon fixation at high CO2. However, the increased primary production did not translate into increased carbon export, and did consequently not work as a negative feedback mechanism for increasing atmospheric CO2 concentration.

Desafios 2012: a noção de número racional em alunos do 4º ano de escolaridade

Com este estudo pretendi perceber as estratégias e dificuldades que persistem em alunos que supostamente terão sido alvo de um trabalho com números racionais nos primeiros anos de escolaridade, mais concretamente perceber a noção de partilha equitativa, bem como de comparação de frações dos referidos alunos. Decorre do referido objetivo as seguintes questões de investigação: (1) Que estratégias e dificuldades apresentam os alunos na resolução de situações de partilha equitativa? (2) Que estratégias e dificuldades apresentam os alunos na comparação de números racionais? Para atingir o objetivo pretendido recorri a uma investigação de cariz interpretativo, abordagem essencialmente qualitativa e pesquisa documental, pelo que analisei as provas de Matemática realizadas por 1330 alunos de 21 agrupamentos do Distrito de Leiria, no âmbito do concurso “DESAFIOS 2012”, mais concretamente as respostas dadas a uma tarefa relativa aos números racionais. De salientar que os alunos que participaram no concurso “DESAFIOS 2012”, frequentaram o 1.º ciclo do ensino básico, j�� no âmbito da entrada em vigor do Programade Matemática do Ensino Básico - PMEB (ME, 2007). Os resultados levam a concluir que uma das estratégias mais usada é o recurso à modelação da tarefa para a partilha equitativa das sandes, bem como formas intuitivas de pensamento para a comparação de frações. As dificuldades prendem-se essencialmente com a modelação da tarefa e identificação das quantidades envolvidas, bem como o recurso ao pensamento diferencial para a comparação das frações.

Women’s football. Notes for a social history of women’s sport in Spain, 1900-1936

In the context of demands by the European feminist movement at the beginning of the 20th century, in Spain women’s sport flagged up aspirations to what were considered to be male practices. The first experiences of women in football stand out because of their use of the media to appear as a symbol of social transformation to modernity in the 20th century. It was not in vain that women’s football highlighted the demands of the feminist movements, although it did come up against male disapproval from an opposing group. The research sets out from a bibliographical and media review of specialist press and sports news of the time. Other current studies have also been considered in order to place it in a social and historical focus on sport. This has enabled us to highlight that football in Spain was established as an unequivocal space for (re) producing male hegemony where women were relegated to the representation of a symbolic ritual in a scenario of accessory and condescension.
