The James-Stein estimator is a biased shrinkage estimator with uniformly smaller risk than the risk of the sample mean estimator for the mean of multivariate normal distribution, except in the one-dimensional or two-dimensional cases. In this work we have used more heuristic arguments and intensified the geometric treatment of the theory of James-Stein estimator. New type James-Stein shrinking estimators are proposed and the Mahalanobis metric used to address the James-Stein estimator. . To evaluate the performance of the estimator proposed, in relation to the sample mean estimator, we used the computer simulation by the Monte Carlo method by calculating the mean square error. The result indicates that the new estimator has better performance relative to the sample mean estimator.

This work is part of a research project on the role of translations of African-American literature in Brazil and their relation to issues of identity, discourse and aesthetics. It analyzes the translation, by Affonso Blacheyre, of Giovanni's room (1956), by James Baldwin, which was published in 1967 in Brazil. Baldwin is revered for his role in the Civil Rights Movement, having produced works that portray the contradictions of a democratic, but, at the same time, racist society. Giovanni's room was first rejected by his publisher for addressing homosexuality. The text displayed on the book flaps of the translation praises Baldwin's "work with language", in contrast to his anti-racism in other works. The praise of aesthetics of Giovanni's room is noteworthy, in contrast with the absence of any remarks on its critique of the marginalization of homosexuality. The focus on the aesthetics of the work corresponded to characters speaking a more formal register in the translation. Discourses on identity strengthening were less apparent in the 60s in Brazil in comparison to nowadays. The emphasis on aesthetics represented a seemingly "non-political" gesture that made it less shocking in the context of military dictatorship prevalent in the country at the time.

1. 1. Total hemolysates of Synbranchus marmoratus Bloch, 1795 captured at four different sites in the State of São Paulo, Brazil, showed two different hemoglobin phenotypes when submitted to agar-starch gel electrophoresis on glass slides in basic buffer. 2. 2. Phenotype I was characterized by 3 hemoglobin bands. When the total hemolysate was submitted to cellulose acetate electrophoresis in basic buffer containing 6 M urea and β-mercaptoethanol, Phenotype I showed four globins of the α 1, α 2, β and γ types, with 11.9 ± 1.9 g% total hemoglobin, 45.3 ± 3.6% globular volume, and 26.8 ± 4.4% mean corpuscular hemoglobin concentration (MCHC). 3. 3. Phenotype II showed three groups of hemoglobins, with a total of up to 12 hemoglobin bands. When the total hemolysate was submitted to cellulose acetate electrophoresis in basic buffer containing 6 M urea and β-mercaptoethanol, phenotype II showed five types of globins, denoted types α 1, α 2, γ 1, γ 2 and β, having electrophoretic positions different from those of Phenotype I globins, with 18.1 ± 3.3% total hemoglobin, 47.9 ± 6.4% globular volume, and 37.8 ± 4.4% MCHC. 4. 4. The distribution of the specimens having the two hemoglobin phenotypes is associated with the different geomorphological provinces of the State of São Paulo, suggesting the existence of at least two populational groups of Synbranchus marmoratus. © 1986.
