Involvement and emancipation of the worker. Action research in a university hospital

The present action research article is linked to an ergonomics project in a university hospital. The author's proposal is to focus action on the effective worker involvement required for the creation of spaces / mechanisms within organizations where people can enhance cooperation and deliberation on matters relating to work. For this purpose, a committee was introduced to assist in finding problems and solutions directly in work situations, so that workers could experience relative autonomy allowing them to develop procedures and choose tools appropriate to their own real needs. Based on this organizational implementation and on subsequent interviews, the practical results are analyzed and related to employee involvement. One can conclude that workers in all areas of the organization can be active elements for improving working conditions and productivity in companies.

The process of territorial formation in Brazil is examined in this paper in order to establish, through a study that favors more interior region of Portuguese America, a suitable analytical arsenal geohistorica an interpretation of the built legacy of colonial Lusitanian action on American soil. Thus, it is expected to recover some aspects not yet addressed conclusively by the specialized literature, the importance of colonial territorial nexus in the construction and maintenance of the substrate material on which the new politically independent state would claim jurisdiction after 1822.

Justiça, razão comunicativa e emancipação social: Filosofia do Direito e Teoria da Justiça a partir do pensamento de Jürgen Habermas

Este artigo trata da interelação entre justiça, razão comunicativa e emancipação social. Ao referir-se à justiça e à injustiça, retorna a um tema de fundamental importância para a história da Filosofia do Direito, sem com isto assumir os riscos das teorias metafísicas da justiça. É a partir da teoria do discurso, de Jürgen Habermas, que as condições e os pressupostos para o desenvolvimento de uma noção de justiça pós-metafísica se torna possível. Investigar a tarefa da Filosofia do Direito, e o desafio do conceito de justiça, são tarefas desdobradas nos estudos e debates envolvidos neste texto.

A critical analysis on "Active Learning" in the light of Cultural-Historical Activity Theory (CHAT): Implications to Physics Education and to experimental activities as a particular case.

This is a research paper in which we discuss “active learning” in the light of Cultural-Historical Activity Theory (CHAT), a powerful framework to analyze human activity, including teaching and learning process and the relations between education and wider human dimensions as politics, development, emancipation etc. This framework has its origin in Vygotsky's works in the psychology, supported by a Marxist perspective, but nowadays is a interdisciplinary field encompassing History, Anthropology, Psychology, Education for example.
