"The Keynesian Roots of Stock-flow Consistent Macroeconomic Models: Peering Over the Edge of the Short Period"

This paper argues that institutionally rich stock-flow consistent models—that is, models in which economic agents are identified with the main social categories/institutional sectors of actual capitalist economies, the short period behavior of these agents is thoroughly described, and the "period by period" balance sheet dynamics implied by the latter is consistently modeled—are (1) perfectly compatible with John Maynard Keynes's theoretical views, (2) the ideal tool for rigorous post-Keynesian analyses of the medium run, and (3) therefore crucial to the consolidation of the broad post-Keynesian research program.

"Revisiting (and Connecting) Marglin-Bhaduri and Minsky--An SFC Look at Financialization and Profit-led Growth"

Many heterodox strands of thought share both a concern with the study of different phases or growth regimes in the history of capitalism and the use of formal short-run models as an analytical tool. This text suggests that (1) this strategy is potentially misleading; (2) that the stock-flow consistent (SFC) approach, while providing a general framework that may facilitate the dialogue among those currents, is particularly well suited to all those who think that macroeconomic models may illuminate historical quests; and (3) that the main intuitions may be conveyed through the "benchmark" Post Keynesian SFC model presented by Dos Santos and Zezza (2008), dispensing with the complex computer simulations that are normally employed by SFC authors.

A fração glomalina e a estabilidade de agregados de diferentes Latossolos.

A Glomalina é uma glicoproteina produzida por fungos micorrizicos arbusculares que tem sido associada à formação e estabilização de agregados do solo e à dinâmica no estoque de carbono. O objetivo deste trabalho foi quantificar a fração protéica relacionada à glomalina em quatro diferentes tipos de latossolos e relacioná-la à estabilidade estrutural de agregados, medida por agitação em água. Foram extraídas as frações glomalina de agregados dos tamanhos 0,50 e 0,25 mm com e sem o extrator citrato de sódio, e em seguida estes foram agitados em um aparelho de Y oder. Foram detectadas grandes diferenças entre solos no teor absoluto da fração glomalina e na estabilidade de agregados entre as modalidades de extração, com redução da estabilidade após a extração, concluindo-se que existe efeito dessa fração na estabilidade de agregados

Experimental analysis of lateral impact on planar brittle material: spatial properties of the cracks

The breakup of glass and alumina plates due to planar impacts on one of their lateral sides is studied. Particular attention is given to investigating the spatial location of the cracks within the plates. Analysis based on a phenomenological model suggests that bifurcations along the cracks' paths are more likely to take place closer to the impact region than far away from it, i. e., the bifurcation probability seems to lower as the perpendicular distance from the impacted lateral in- creases. It is also found that many observables are not sensitive to the plate material used in this work, as long as the fragment multiplicities corresponding to the fragmentation of the plates are similar. This gives support to the universal properties of the fragmentation process reported in for- mer experiments. However, even under the just mentioned circumstances, some spatial observables are capable of distinguishing the material of which the plates are made and, therefore, it suggests that this universality should be carefully investigated
