The intensification of the production system in the poultry industry and the vertical integration of the poultry agribusiness have brought profound changes in the physical and social environment of domestic fowls in comparison to their ancestors and have modified the expression of aggression and submission. The present review has covered the studies focusing on the different aspects linked to aggressiveness in the genus Gallus. The evaluated studies have shown that aggressiveness and subordination are complex behavioral expressions that involve genetic differences between breeds, strains and individuals, and differences in the cerebral development during growth, in the hormonal metabolism, in the rearing conditions of individuals, including feed restriction, density, housing type (litter or cage), influence of the opposite sex during the growth period, existence of hostile stimuli (pain and frustration), ability to recognize individuals and social learning. The utilization of fighting birds as experimental material in the study of mechanisms that have influence on the manifestation of aggressiveness in the genus Gallus might comparatively help to elucidate important biological aspects of such behavior.

The aim of this study is to characterize the relationships in innovation and business clustering processes in the productive chain of small and medium enterprises (SME) of Brazil. The object of study are SMEs the local procuctive cluster of the shoes in Franca, State of São Paulo. The conceptual model developed is based on the following constructs: vertical integration, innovation and characteristics of the cluster, and it is focused on identifying the agents that act predominantly in product innovation processes in the cluster. A survey was conducted. It was found that there is cooperation between the companies in the productive arrangement studied, and that shoe manufacturers are those who, predominantly, stimulate innovation within the cluster.

A análise do efeito da profundidade de semeadura e carga vertical visando a melhorar o aproveitamento, e a integração entre o solo e a cultura é muito difícil. O objetivo do presente trabalho foi avaliar cargas verticais (0; 98; 196 e 294 N) sobre as rodas compactadoras das semeadoras, combinando com profundidades de semeadura (0,03; 0,05 e 0,07 m) para a cultura da soja. O trabalho foi realizado no DER/UNESP - Jaboticabal, na pista de ensaio do Laboratório de Máquinas e Mecanização Agrícola (LAMMA), utilizando o delineamento experimental em blocos casualizados, no esquema fatorial (4 x 3), com 12 tratamentos e três repetições, totalizando 36 observações. Foram analisados: emergência de plântulas, estandes inicial e final, índice de sobrevivência, área mobilizada e rendimento de grãos. Os resultados evidenciaram que, com exceção da área mobilizada em relação à profundidade de semeadura, todas as demais variáveis não foram influenciadas pelos tratamentos.
