Clarice Lispector - the hour of the star: the speech in the exhibition pamphlet

This work attempts to discuss, in the light of the French Analysis of the Discourse, how the concept of memory and heterogeneity in language actions can contribute to a reflection on information and documentation studies. Starting from cuttings of Clarice Lispector - the hour of the star exhibition pamphlet, accomplished in the second semester of 2007 by the Portuguese Language Museum (Luz train station, Sao Paulo), we interpreted the several voices that surround and sustain the subject and the sense.

A History of Eating in Sao Paulo (1920 to 1950)

This paper proposes a way to analyze the history of eating in Sao Paulo (Brazil) between 1920 and 1950. It addresses the relative absence of research on this topic for this period characterized by the rapid expansion of the city, which became a key market, an important regulator of consumption habits, and a meeting place for diverse social groups. An abundance of sources makes it possible to undertake a social history of eating. On the one hand, intellectuals of different backgrounds and interests produced a good deal of work on popular food habits. On the other, the article points to the possibility of using lifestyle studies and surveys on eating habits from this period in order to gain insight into the lives of different sectors of the population.

Canonical discriminant analysis applied to broiler chicken performance

The mechanisms involved in the control of growth in chickens are too complex to be explained only under univariate analysis because all related traits are biologically correlated. Therefore, we evaluated broiler chicken performance under a multivariate approach, using the canonical discriminant analysis. A total of 1920 chicks from eight treatments, defined as the combination of four broiler chicken strains (Arbor Acres, AgRoss 308, Cobb 500 and RX) from both sexes, were housed in 48 pens. Average feed intake, average live weight, feed conversion and carcass, breast and leg weights were obtained for days 1 to 42. Canonical discriminant analysis was implemented by SAS((R)) CANDISC procedure and differences between treatments were obtained by the F-test (P < 0.05) over the squared Mahalanobis` distances. Multivariate performance from all treatments could be easily visualised because one graph was obtained from two first canonical variables, which explained 96.49% of total variation, using a SAS((R)) CONELIP macro. A clear distinction between sexes was found, where males were better than females. Also between strains, Arbor Acres, AgRoss 308 and Cobb 500 (commercial) were better than RX (experimental), Evaluation of broiler chicken performance was facilitated by the fact that the six original traits were reduced to only two canonical variables. Average live weight and carcass weight (first canonical variable) were the most important traits to discriminate treatments. The contrast between average feed intake and average live weight plus feed conversion (second canonical variable) were used to classify them. We suggest analysing performance data sets using canonical discriminant analysis.
