This paper discusses, within the prevaling Brazilian situation, the possibility of applying 'Causal Tree' (CT) method in investigating occupational accidents by safety personnel in the public health services and workers' unions. The method was developed during the seventies in France, for use by plant safety personnel. The authors used this method in Botucatu, State of Sao Paulo, Brazil, in order to investigate 40 serious occupational accidents that occurred in industrial plants during the second half of 1993, that had been registered by Social Security. In these cases, the predominance of situations in which the lack of safety measures were identified by inspection indicates that in most instances, the use of CT is unnecessary. However, the authors discuss its use by safety personnel from the public health services and workers' unions to investigate certain accidents to contribute to the knowledge base and help overcome the cultural based guilt which, in Brazil, has turned the victim into the person responsible for the accident.

Contractors Odebrecht, Camargo Correa and Andrade Gutierrez play an important role in Brazil's economy stressed by the number of jobs they add, capital accumulation and diversification through the acquisition of state firms and assets. Abroad, they rank among the top companies in the industry. Is there a behavioral standard among these firms? How did they grow? Why did they diversify? What triggers them to internationalization and what are the strategies they adopt in the foreign markets? The attempt to shed light on these questions resulted in the observation of patterns inside Brazilian market as they grew and diversified, but such a pattern could not be detected in the internationalization process
