Gestão da Cadeia de Suprimentos e Sustentabilidade: um estudo bibliométrico da produção científica na base Web of Science

Este artigo analisou as caracteristicas das publicacoes relacionadas aos temas Gestao da Cadeia de Suprimentos e Sustentabilidade. A pesquisa foi realizada na base de dados Web of Science da ISI Web of Knowledge, procurando identificar as principais areas tematicas, autores, tipos de documentos, titulo das fontes, ano das publicacoes, instituicoes, idiomas e paises destas publicacoes, assim como a identificacao dos “hot topics” relacionados aos topicos “Supply Chain Management and Sustainability” e relacionou as publicacoes mais citadas com os autores que mais publicam na tematica pesquisada. A analise dos dados teve por base os calculos dos indices h-b e m de Banks (2006). De acordo com os resultados deste estudo, o numero de publicacoes cresceu de forma significativa no periodo analisado, concentrando-se nos Estados Unidos, com 99% das publicacoes escritas no idioma ingles tendo como principal fonte o periodico Journal of Cleaner Production, e como principais temas: Business Economics (Economia) e Engineering (Engenharia). Dentre os 20 topicos combinados com o tema pesquisado, Management (Gestao) e Performance (Desempenho) se destacaram como “hot topics”.Constatou-se ainda que a publicacao com o maior numero de citacoes, sendo uma referencia na tematica pesquisada nao pertence aos autores que mais publicam sobre o mesmo tema.

The Innovation Process and the Development of a Sustainability Strategy

ABSTRACT This article analyzes what influences a firms choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy.

ANÁLISE DE BENEFÍCIO - CUSTO LEVANDO-SE EM CONSIDERAÇÃO OS CUSTOS DA ÁGUA DE IRRIGAÇÃO PARA O ARROZ

The water’s relevance has been increasing in the context of irrigated agriculture, both in a quantitative and qualitative aspect. The cost analyses usually don’t take into consideration the aspects related to the water’s quality and treatments that are employed to make it proper to use. As the control over the use of hydric resources increases, it forces the agriculture to make use of low quality waters, what may come to turn its costs even more expensive. The present study aimed at realizing a cost benefit analysis taking into consideration the expenses with water employed to irrigate rice crops. It took place at the campus of the Federal University of Santa Maria – RS, from the analysis of two water reservoirs. After calculating the water’s quality rate as well as the expenses with its treatment and the water itself, the current rice production costs were then added to the final outcome, making possible to obtain a cost benefit ratio. This cost benefit ratio was less than one unit in all situations, showing that the irrigated rice production is currently impracticable. The water costs weren’t decisive for this outcome, but regarding to the price of a rice sack, it was higher than the inflation values in 2010. Finally, it was possible to conclude that the water cost is responsible for 7% of the production cost, what makes this research an efficient tool to help decision making processes when managing irrigation systems.
