Estados sobre a alimentação mineral do cafeeiro: XVII - efeito da adubação NPK na composição química do solo, do fruto e na qualidade da bebida (Nota preliminar)

Foram feitas determinações dos teores de N, P e K no solo e nos frutos de cafeeiros submetidos a um ensaio fatotorial 2x2x2. Verificou-se que apenas as aplicações de P e K elevaram os teoresdos elementos no solo. O uso de N e K aumentou o teor dêsses nutrientes no fruto. A qualidade da bebida foi prejudicada pela falta de P na adubação.

Estudos sobre a nutrição mineral do arroz: XVII. Exigências nutricionais das variedades IAC-164 e IAC-165

Duas variedades de arroz de sequeiro, IAC-164 e IAC-165, foram cultivadas em solução nutritiva até o fim do ciclo. Foi feita a determinação da matéria seca das raízes, colmos+perfilhos, folhas, casca e grãos. Nas diversas partes foi feita a determinação dos teores de macro e micronutrientes. Os macronutrientes foram exigidos na seguinte ordem decrescente: IAC-164 - K, N, Ca, Mg, P e S; IAC-165 - N, K, Ca, P - Mg, As duas variedades exportaram (grãos + casca) os elementos na ordem decrescente seguinte: N, K, P, Mg, Ca, S. As exigências de micronutrientes por sua vez, guardaram a ordem decrescente: IAC-164 - Cl, Fe, Zn, Mn, Cu, B, Mo; IAC-165 - Cl, Fe, Mn, Zn, Cu, B, Mo. A exportação obedeceu a esta ordem para as duas variedades: Cl, Zn, Fe, Mn, Cu, B e Mo. As exigências nutricionais das duas variedades não foram as mesmas.

The Barcelonnettes: an example of network-entrepreneurs in XIX century Mexico. An explanation based on a theory of bounded rational choice with social embeddedness

A theory of network-entrepreneurs or "spin-off system" is presented in this paper for the creation of firms based on the community’s social governance. It is argued that firm’s capacity for accumulation depends on the presence of employees belonging to the same social/ethnic group with expectations of "inheriting" the firm and becoming entrepreneurs once they have been selected for their merits and loyalty towards their patrons. Such accumulation is possible because of the credibility of the patrons’ promises of supporting newcomers due to high social cohesion and specific social norms prevailing in the community. This theory is exemplified through the case of the Barcelonnettes, a group of immigrants from the Alps in the South of France (Provence) who came to Mexico in the XIX Century.

Why did London become the main money market? Monetary Policy, Arbitrage and European Money Market Integration in 18th century

How did the leading capital market start to attract international bullion? Why did London become the main money market? Monetary regulations, including the charges for minting money and the restrictions on bullion exchange, have played the key role in defining the direction of the flow of international bullion. Countries that abolished minting charges and permitted the free movement of bullion were able to attract international bullion, and countries that applied minting taxes suffered an outflow of bullion. In these cases monetary authorities tried to limit bullion movement through prohibitions on domestic bullion exchange at a free price, and tariffs and quantitative restrictions on bullion exports. The paper illustrates the logic of international monetary flow in the 18th century, using empirical evidence for England, France and Spain. The first section defines and measures monetary policy, and the second section introduces minting charges into the arbitrage equation in order to explain the logic of bullion flow between the pairs of nations England-France, England-Spain and France-Spain. The conclusion emphasises the importance of monetary policy in the creation of leading money markets.
