Estudos sôbre nematóides Filarídeos: genótipo de Dipetalonema Diesing, 1861; valor dos gêneros Acanthocheilonema Cobbold, 1870 e Breinlia Yorke & Maplestone, 1926

The author divides the article in thee parts. In the first part he studies the literature on the genotype of Dipetalonema DIESING, 1861 - D. caudispina (MOLIN, 1858), and gives a new generic diagnosis of the Diesing's genus, based upon its type species. In the second one he studies the literature on the validity of Acanthocheilonema COBBOLD, 1870, and, comparing both generic defvinition and type-species description of Acanthocheilonema dracunculoides COBBOLD, 1870 and Dipetalonema caudispina (MOLIN, 1858), concludes that Cobbold's genus Acanthocheilonema must be, definitely, considered as a synonym of Dipetalonema DIESING, 1861. In the third part a comparative study, based on the literature, is made between generic definitions and type-species descriptions of Breinlia trichosuri (BREINL, 1913) and Dipetalonema caudipina (MOLIN, 1858), and the author concludes that Breinlia must be considered as a valid genus, distinguished from Dipetalonema, principally, by the morphology fo the longer spicule.

Gerogescu-Roegen versus Solow/Stiglitz and the convergence to the Cobb-Douglas

The value of the elasticity of substitution of capital for resources is a crucial element in the debate over whether continual growth is possible. It is generally held that the elasticity has to be at least one to permit continual growth and that there is no way of estimating this outside the range of the data. This paper presents a model in which the elasticity is determined endogenously and may converge to one. It is concluded that the general opinion is wrong: that the possibility of continual growth does not depend on the exogenously given value of the elasticity and that the value of the elasticity outside the range of the data can be studied by econometric methods.
