Standard oil company: um reflexo da industrialização americana

A Standard Oil Company foi resultado da forte industrialização que ocorreu nos Estados Unidos após a Guerra de Secessão. Anterior ao conflito, os americanos estavam divididos entre ser tornarem um país exportador de matérias primas ou serem industrializados. Mesmo que ambas as estruturas econômicas foram aplicadas concomitantemente, trazendo recursos financeiros para a Nação, os estados do Norte acabaram vencendo a guerra e incentivaram a expansão industrial. O reflexo desse processo foi notado pelo empresário J.D. Rockefeller que inicia sua empresa baseada na exploração de petróleo, a Standard Oil Company. Utilizando-se de métodos eficientes, inovadores e eficazes, proporcionou um aumento na produção petrolífera de forma exorbitante, podendo manter altos níveis de lucro, mesmo que a preços razoáveis ao consumidor. O impacto da organização industrial e as estratégias encontradas pelo monopólio marcaram profundamente a economia americana. Mesmo sendo um tema de história econômica, no decorrer deste trabalho utilizaremos aspectos sociológicos, biográficos e estatísticos para compreendermos de que forma a Standard Oil Company representa a essência do espírito capitalista da instituição americana

Relationships between company size, types of production system and supply chain management: evidence from electro-electronics sector in Brazil

Purpose – The purpose of this paper is to investigate how company size and the type of production system affect the adoption of supply chain management (SCM) practices in companies in the electro‐electronics sector in Brazil. Design/methodology/approach – An e‐mail survey of 107 companies associated with the Brazilian Electrical and Electronics Industry Association (ABINEE) was conducted. Statistical techniques were employed to verify the adoption of SCM practices according to the size of the company and its production system. Findings – The major results indicate that the larger the size of the company, the higher the level of adoption of SCM practices, and that the choice of SCM practices depends upon the type of production system implemented. Practical implications – The implications of this study are useful to top management leaders of small and medium‐sized enterprises since the findings enable them to identify the most common practices adopted by either large‐, medium‐ or small‐sized companies in order to benchmark the level of adoption of SCM practices. Production managers can also benefit from this study by identifying the SCM practices that may support certain production systems.

Greening a Brazilian cotton seed processing company: from challenges to strategic opportunities

This paper aims to shed light on a current and important theme that has been gaining increasing importance for governments, society and companies: the greening of agricultural companies in developing countries. The research objective is to classify a Brazilian cotton seed processing company in the evolutionary stages of environmental management: reactive, preventive or proactive. Design/methodology/approach– A case study was conducted in a Brazilian cotton seed processing company.Findings– The main results are: the studied company is positioned in the preventive stage of environmental management; this company is investing in operational green practices; environmental management in this company is motivated by various factors aiming at an increased competitive advantage. Finally, it can be concluded that this company is looking for green opportunities towards the proactive environmental management stage.

Avaliação do potencial de reuso agrícola do efluente de uma estação de tratamento de esgoto com alagados construídos

The study took place in a sewage treatment plant located at the actual Department of Water and Sewer in Bauru, city of Sao Paulo state. This treatment plant has an average entrance flow of 4.8 l. s-1 made by upflow anaerobic filter, followed by wetland systems constructed in parallel. . As objective of this study we evaluate the effectiveness of three systems of constructed wetlands, with three different types of plants (Lily pond, Giant papyrus and Cattail),quantify, and qualify the effluents at various stages of treatment to monitor their effectiveness and the possibility of reuse in agriculture. There was a satisfactory removal of organic matter, with a mean concentration of 36 and 39mg.l-1 at the , phases 1 and 2 of the operation, respectively. The constructed wetlands effluent nitrogen and phosphate concentrations were high throughout all the system and the removal efficiency of ammonia nitrogen was much lower than expected, then the system is functioning as secondary treatment and not as tertiary treatment. The concentrations of micro-organisms found in the final effluent were also high. Therefore, it is concluded that the results of removal efficiency of organic matter, of constructed wetland systems, meet the parameters required by legislation for effluent discharges but do not attend the parameters required for nitrogen and micro organisms. This way, these analyzed plants effluents are suitable for reuse in agriculture restricted irrigation
