Em Pelos olhos do menino de engenho, a socióloga Carla de Fátima Cordeiro busca identificar um pensamento social relativo à questão racial no Brasil na década de 1930, a partir da análise dos personagens negros presentes na obra de José Lins do Rego. Descendente de senhor de engenho, o escritor paraibano, ao lado de Gilberto Freyre, foi um dos mais destacados participantes do Movimento Regionalista Nordestino, que defendia os verdadeiros valores brasileiros, baseados na ordem social anterior: latifundiária, escravista e açucareira. Lins do Rego criou seus principais romances, considerados fortemente autobiográficos, entre 1934 e 1942, época em que as velhas estruturas econômicas e de relações sociais dos engenhos de cana-de-açúcar se encontravam em franco declínio. A autora traz à luz um processo fundamental da História do país, concluindo que o processo de decadência dos velhos modos de produção refletiu-se na narrativa dos romances, em que a violência, principalmente contra os subalternos negros, tornou-se cada vez mais presente. Dessa forma, ela demonstra como a ficção literária expressou o comportamento do poder patriarcal, que passou a sentir-se ameaçado pela inevitável introdução do trabalho livre.

An experiment was conducted to evaluate the performance, bone densitometry and carcass yield of broilers chicks, using different levels of phytase enzyme. Nine hundred and sixty male one-day-old broiler chicks were used. The birds were distributed in a completely randomized experimental design, involving five treatments and six replications of 32 chicks each. The treatments consisted of a control diet for each phase, and four other diets were formulated adding growing levels of the phytase enzyme (250, 500, 750 and 1,000 FTU of phytase kg-1 feed). When adding the phytase enzyme, the nutritional matrix was valued to guarantee the same nutritional levels as the control diet. In general, the addition of phytase enzyme determined a linear decrease on the performance of the birds. However, the performance obtained with the level of 250 FTU phytase kg-1 feed were no different from the control treatment. The best bone density results were observed in the control treatment with no phytase, and the highest leg and thigh yield were obtained at the level of 514 FTU phytase kg-1.

Introduction: Biomechanical analysis of gait can be used effectively to identify changes in movement patterns and functional decline. Objective: To analyze the effect of dual task on gait spatio-temporal variables. Methods: The sample was made up of 32 subjects of both genders aged between 18 and 25 years. The test Timed Up and Go was performed under two conditions: original form and associated with a cognitive task (verbalize backwards the months of the year). We evaluated the total execution time, number of steps, cadence, time spent to lift, average speed and variability of the step time. Results: Significant changes were observed with the addition of the cognitive task in many gait spatio-temporal variables analyzed. Conclusion: The tests showed that the increase of cognitive tasks during walking may lead to changes in the performance of this task.

The aim of this article is to reflect on the relationship between the United States and China in the 21th. Century. By observing trends of economic, political and also military indicators, we can note that the trajectories of the United States and China tend to cross, with a relative decline of the first and the fast Chinese rise. This situation makes us believe to suppose the occurrence of possible dispute for world hegemony between the two countries in medium and long term. Because of this, we assume that the strategy of "A American Century in Asia-Pacific" fits in an attempt to test the Chinese commitment to "peaceful development" and its guarantee of maintaining the stability of international relations.
