Improved maximum-likelihood estimation in a regression model with general parametrization

We analyse the finite-sample behaviour of two second-order bias-corrected alternatives to the maximum-likelihood estimator of the parameters in a multivariate normal regression model with general parametrization proposed by Patriota and Lemonte [A. G. Patriota and A. J. Lemonte, Bias correction in a multivariate regression model with genereal parameterization, Stat. Prob. Lett. 79 (2009), pp. 1655-1662]. The two finite-sample corrections we consider are the conventional second-order bias-corrected estimator and the bootstrap bias correction. We present the numerical results comparing the performance of these estimators. Our results reveal that analytical bias correction outperforms numerical bias corrections obtained from bootstrapping schemes.

Georgics of the mind and the architecture of fortune: Francis Bacon's therapeutic ethics

This essay complements recent work by Soreana Corneanu situating Bacon’s epistemology in a larger lineage of literature concerning ‘cultura animi’ in early modern Europe, by focusing on Bacon’s conception of a therapeutic philosophical ‘Georgics of the mind’ in The Advancement of Learning, the Essays, and other texts. We aim to show firstly (in Part 2) how Bacon’s conception of human nature, and the importance of habit and custom, reflects the ancient pagan thinkers’ justifications of philosophical therapeutics. Attention will also be paid in this connection to Bacon’s sensitivity to another marker of ancient therapeutic philosophy as Pierre Hadot in particular has recently presented it: the proliferation of different rhetorical and literary forms aiming at different pedagogic, therapeutic, and psychogogic aims. Part 3 then will examine Bacon’s changes in practical or ‘magistral’ philosophy, carried out on the therapeutic ethical grounds which Part 2 has examined, but proposing a much more active ‘architecture of fortune’ to philosophical and political aspirants.

As vozes e as coisas: a poesia em prosa de Murilo Mendes e Francis Ponge

O livro compara duas importantes obras de poesia em prosa das literaturas brasileira e francesa, o Poliedro, de Murilo Mendes e o Le parti pris des choses, de Francis Ponge, publicadas respectivamente em 1972 e 1942. Para a autora, a aproximação se justifica pelo foco dado nas duas obras aos objetos mais cotidianos possíveis e, ainda, pelo posicionamento diferente dos sujeitos líricos muriliano (menos objetivo) e pongiano (mais objetivo) diante das coisas simples do mundo. O brasileiro e o francês também partilhariam de uma determinada comunidade de interesses históricos, literários e sociais, ainda que as obras em questão estejam separadas por um intervalo de publicação de trinta anos e, neste intervalo, tenham ocorrido acontecimentos políticos, sociais e artísticos que reverberaram inevitavelmente na literatura desses poetas. Para a autora, a própria escolha da forma do poema em prosa pelos dois autores também os uniria, na medida em que este formato contribuiu enormemente para a construção singular dos objetos, bem como das duas vozes líricas tão particulares

Murilo Mendes, Francis Ponge e o poema em prosa

The present paper aims to discuss the configuration of the prose poem both in the works of Murilo Mendes' Poliedro (1972) and Francis Ponge's Le parti pris des choses (1942). From the beginning, the similarity between both works is explained by the impulse of focusing on daily objects and also the diverse positioning of the lyrical subjects in Murilo Mendes (less objective) and Francis Ponge (more objective) when they establish a relation with the simple things they wish to marvel. In accordance, the form of the prose poem helps to build this specific and singular view of the objects. Using this background to dialogue with the critical scholarly resources on both writers, we briefly analyse some poems and set out to reflect on the prose poem, which holds the works of the Brazilian and the French poets open to comparison.

Estudo e modelagem 3D de uma turbina Francis

Most of the hydraulic turbines that are running in the world are the Francis type, because they are able to fit a wide range of head and flow. We also can declare that most of the installed hydraulic energy up to this date is generated by this type of turbine. On the other hand, if we pay attention to mechanical details of a Francis turbine we will see that among the three most used types it is the one that presents the more complex design. And, the simplest one is the Pelton type, whereas the Kaplan is the one less utilized. This work aims to develop the hydrodynamic calculation of a Francis turbine as well as to obtain its assembly drawing and 3D modeling drawing. In this way all details must be shown therefore needing a complete knowledge about this issue. Both 2D and 3D drawings help much if one wants the machine to be running in its power house. It is well noted that most of the entities that design and manufacture the Francis turbines are not brazilian. In this way the more we study how to design this kind of machine the more is our contribution to our country in order to conquer technology and manufacture Francis turbines
