The construction of organizational identity: discourses on a Brazilian private railroad

Considering the current organizational macro-environments, we notice that competitors have become more aggressive. At the same time, some stakeholders are expecting more from organizations in relation to social and environmental issues. Therefore, in order to survive in this context, it is crucial for organizations to know better their identity, which is projected by different means of communication to its internal members and external public. In this scenario, the aim of this paper is to analyze the projected organizational identity of a recently privatized Brazilian railroad. We studied the construction and transformation process of this organizational identity through two different discourses: that of the high-level manager and that of the trade union. In addition, two Discourse Analysis elements were used: the persuasion strategies and the discursive images. These elements were very useful in order to apprehend the ideological background of the discourses and the organizational identity projected. In the end, we concluded that the identity projection process occurs in a very diverse, contradictory and interactive way.

Evaluation of operational parameters from a microfiltration system for indigo blue dye recovery from textile dye effluent

AbstractThis study aims to evaluate the use and operational parameters for microfiltration system (MF) for recovery of insoluble indigo blue present in the dye bath water of the cotton yarn, in order to reuse the pigment and water washing. The results showed that MF process is a promising technology for the recovery of insoluble indigo blue presents in a synthetic wastewater. The longitudinal module, when compared with the submerged module, presented a better performance showing removal efficiency of color and chemical oxygen demand (COD) of 99 and 94%, respectively. The dye recovery operation was performed at low pressure, specifically 0.3 bar, value determined by analysis of critical flux. The process was carried out under a laminar flow with Reynolds values of 1,900 and 2,850 and a turbulent flow with Reynolds values of 3,800 and 4,700 that achieved a recovery rate of 89.7% under minimal fouling conditions.

Pós-modernidade e etnografia nas organizações

A obra e uma coletânea de textos diferenciados sobre a dinâmica organizacional. Objetiva-se desconstruir a realidade, atraves do metodo etnografico e da visao pos-moderna. O resultado sao analises que cobrem desde um shopping center a uma escola para criancas cegas, passando pelas historias em quadrinhos, entre outros temas. O livro contribui para a teoria organizacional, pois desvenda aspectos inexplorados nas organizacoes brasileiras e traz a tona metodologias inovadoras e pertinentes

As modernas técnicas de reprodutibilidade: adestramento ou resistência?

O objetivo do presente trabalho e resgatar o debate entre dois importantes pensadores da escola alema de Frankfurt, Theodor Adorno e Walter Benjamin, a respeito dos impactos politico-sociais dos processos de reprodutibilidade e de massificacao da cultura. Primeiramente, no plano teorico, destacam-se os principais pontos de vista dos autores, os quais, algumas vezes, se mostram divergentes. Posteriormente, no plano empirico, aplicam-se elementos da Analise do Discurso em reportagens de duas revistas brasileiras, a Veja e a Caros Amigos. Ao final, procura-se refletir, a luz das ideias de Adorno (1978) e de Benjamin (1982), sobre as diferencas ideologicas evidenciadas entre as duas revistas, seu posicionamento e sua funcao na sociedade brasileira contemporânea. Palavras-chave: industria cultural, midia de massa, resistencia, Adorno e Benjamin.
