Este estudo analisou os recursos internos de Tecnologia da Informação (TI) como sustentadores de vantagem competitiva sob a óptica da Visão Baseada em Recursos (VBR). A análise investigou 17 atributos estratégicos em um estudo qualitativo de caráter exploratório e com um histórico longitudinal. Cada um dos atributos foi devidamente identificado, caracterizado e conceituado pelos seus respectivos autores, seguidores da VBR, antes de ser utilizados nas análises. O estudo de casos múltiplos considerou a dinâmica competitiva de duas organizações, líderes do setor metal-mecânico e significativamente competitivas em inovação tecnológica. As narrativas de 16 executivos (12 CEOs e quatro CIOs) contribuíram para a reconstituição de vinte anos de competitividade empresarial, tendo sido considerados eventos econômicos relevantes ou fases críticas identificadas no período estudado. Ao finalizar a recuperação da trajetória percorrida pela dinâmica competitiva, e, uma vez identificados os recursos e os momentos críticos de maior competitividade, os executivos seniores foram encorajados a se posicionar quanto ao potencial estratégico dos recursos. A compreensão das intervenções de TI na dinâmica competitiva foi importante para estudar como, de acordo com o instrumento adotado, a TI apoia a competitividade segundo os critérios da VBR. A análise de conteúdo, segundo as proposições de Bardin, trata do desvendamento de significações de diferentes tipos de discursos, baseando-se na inferência ou dedução, mas que, simultaneamente, respeita critérios específicos propiciadores de dados em estruturas temáticas. Os recursos de TI não contribuíram estrategicamente, pelo menos de forma dissociada dos demais recursos, durante as fases críticas da competitividade nas duas organizações. As duas organizações reconheceram que a utilização conjunta de diferentes recursos de TI pode representar a força maior na criação de novas estratégias e manutenção das estratégias mais antigas. Dentre os principais resultados, o estudo revelou os diferentes atributos estratégicos de TI interagindo com as fases críticas da competitividade nas organizações estudadas. Esses atributos foram fundamentados nos recursos denominados Configurador de Produto (CP), Módulo Comercial (MC) e Manufatura Virtual (MV).
Faced with the increasing demand for renewable energy, researchers have developed several ways to generate them, such as biogas. Thus, the present study aims to demonstrate the economic viability of electricity generation from biodigesters in a pig farm to contribute to sustainable development by reducing pollution in the environment. Studies focused on biomass derived from pig waste are still scarce. Moreover, one of the motivations of the present study is the fact that Brazil is a major producer and exporter of pig meat, with most of the production taking place in the south and southeast regions. The methodology used is defined as exploratory, descriptive, explanatory, and applied. The scientific procedures were documentary and bibliographic research, case study, and cost analysis. An economic management model was developed using financial management instruments such as cash flow, internal rate of return, and simple and discounted payback, confirming the economic viability of the investment made for generating energy from animal biomass produced in a pig farm located in the interior of Rio Grande do Sul.
The exhaust dust is an industrial waste that results from the sand molded casting process in the foundry sector. The metal casting industry plays an important role in the reduction of the environmental impact by recycling industrial waste. The idea of manufacturing thermally resistant refractory bricks made of exhaust dust from the foundry industry has motivated managers and researchers. The purpose of this study is to analyze the manufacturing process of refractory bricks made of 10, 20 and 30% exhaust dust and their properties. The dust was analyzed by using the SEM/EDX and XRD techniques. Results show that the specimens used in this study did not meet the required water absorption specifications. However, the 10% and 20% samples presented a desirable porosity. The manufactured bricks were classified as dense, insulating and semi-insulated, respectively. In relation to compression resistance the rupture stress proved to be lower than the level of stress detected in commercial bricks. The temperature test showed that bricks made of exhaust dust cannot be considered refractory for commercial purposes. Although the exhaust dust does have some refractory properties it still cannot be used as raw material in the manufacturing of refractory bricks since it does not meet all the necessary specifications as proposed by this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
