Knowledge management and strategic orientation: leveraging innovativeness and performance

Purpose - The aim of this study is to investigate whether knowledge management (KM) contributes to the development of strategic orientation and to enhance innovativeness, and whether these three factors contribute to improve business performance. Design/methodology/approach - A sample of 241 Brazilian companies was surveyed, using Web-based questionnaires with 54 questions, using ten-point scales to measure the degree of agreement on each item of each construct. Structural equation modeling techniques were applied for model assessment and analysis of the relationships among constructs. Exploratory factor analysis, confirmatory factor analysis, and path analysis using the technique of structural equation modeling were applied to the data. Findings - Effective KM contributes positively to strategic orientation. Although there is no significant direct effect of KM on innovativeness, the relationship is significant when mediated by strategic orientation. Similarly effective KM has no direct effect on business performance, but this relationship becomes statistically significant when mediated by strategic orientation and innovativeness. Research limitations/implications - The findings indicate that KM permeates all relationships among the constructs, corroborating the argument that knowledge is an essential organizational resource that leverages all value-creating activities. The results indicate that both KM and innovativeness produce significant impacts on performance when they are aligned with a strategic orientation that enables the organization to anticipate and respond to changing market conditions. Originality/value - There is a substantial body of research on several types of relationships involving KM, strategic orientation, innovativeness and performance. This study offers an original contribution by analyzing all of those constructs simultaneously using established scales so that comparative studies are possible.

Análise das relações entre estratégia de produção, práticas e desempenho operacional

Este trabalho teve o objetivo de verificar quais são as melhores práticas de produção para o setor moveleiro no Brasil, mediante a análise das relações entre as práticas de produção implantadas e prioridades competitivas e, também, entre indicadores de desempenho. A revisão teórica centrou em definir o pressuposto para o estudo das melhores práticas e realizar uma sistematização da literatura. Posteriormente, foi desenvolvida a pesquisa prática mediante uma survey em 99 empresas. Para a análise dos dados, foi empregada a técnica de modelagem de equações estruturais com o método de estimação dos mínimos quadrados ponderados. Os resultados revelaram que as práticas nas áreas de desenvolvimento de novos produtos, recursos humanos e planejamento e controle de produção estavam alinhadas à estratégia de produção e contribuíram para a melhoria de indicadores de desempenho operacional, sendo assim consideradas melhores práticas para o contexto estudado. Foram feitas discussões e sugestões para pesquisas futuras.

Qualidade do relato dos procedimentos metodológicos em periódicos nacionais na área de administração de empresas: o caso da modelagem em equações estruturais nos periódicos nacionais entre 2001 e 2010

Esta pesquisa teve o objetivo de avaliar a qualidade da descrição dos procedimentos metodológicos de artigos que utilizaram a modelagem em equações estruturais (MEE), incluindo a análise fatorial confirmatória e a path analysis, e que foram publicados na RAE, RAUSP, REAd, O&S, RAC e RAE-eletrônica entre 2001 e 2010. A partir da revisão da literatura metodológica, foi elaborado um check list para avaliar as treze etapas da MEE, sendo validado com 33 especialistas. Os principais resultados da análise de 68 artigos encontrados foram: a impossibilidade de replicar os estudos devido à falta de informações e o uso de estratégias exploratórias sem a posterior validação. Por outro lado, a justificativa do método utilizado e a explicação das implicações teóricas dos resultados são aspectos que têm sido atendidos plenamente. O check list foi um importante subproduto desta pesquisa, pois, a partir dele, são propostas novas linhas de investigação e até mesmo seu uso como ferramenta didática.

Modeling random corrosion processes via polynomial chaos expansion

Polynomial Chaos Expansion (PCE) is widely recognized as a flexible tool to represent different types of random variables/processes. However, applications to real, experimental data are still limited. In this article, PCE is used to represent the random time-evolution of metal corrosion growth in marine environments. The PCE coefficients are determined in order to represent data of 45 corrosion coupons tested by Jeffrey and Melchers (2001) at Taylors Beach, Australia. Accuracy of the representation and possibilities for model extrapolation are considered in the study. Results show that reasonably accurate smooth representations of the corrosion process can be obtained. The representation is not better because a smooth model is used to represent non-smooth corrosion data. Random corrosion leads to time-variant reliability problems, due to resistance degradation over time. Time variant reliability problems are not trivial to solve, especially under random process loading. Two example problems are solved herein, showing how the developed PCE representations can be employed in reliability analysis of structures subject to marine corrosion. Monte Carlo Simulation is used to solve the resulting time-variant reliability problems. However, an accurate and more computationally efficient solution is also presented.

Environmental management in Brazil: is it a completely competitive priority?

Current studies indicate a need to integrate environmental management with manufacturing strategy, including topics like cross-functional integration, environmental impact, and waste reduction. Nevertheless, such studies are relatively rare, existing still a need for research in specific regional contexts. At the same time, the results found are not unanimous. Due to these gaps, the objective of this article is to analyze if environmental management can be considered a new competitive priority for manufacturing enterprises located in Brazil. A cross-sectional survey was conducted with Brazilian companies certified by ISO 14001. Sixty-five valid questionnaires were analyzed through Structural Equation Modelling (SEM). The first conclusion is that environmental management presents a preventive approach in the sample analyzed, focused on eco-efficiency, what potentially do not to create a competitive advantage. This preventive approach inhibits environmental management from being regarded as a new competitive manufacturing priority, in the full sense as defined by the literature. Another important result is that environmental management, although following a preventive focus, may influence positively the four manufacturing priorities: cost, quality, flexibility and delivery.

Income inequality and elderly self-rated health in Sao Paulo, Brazil

Purpose: To test the association between income inequality and elderly self-rated health and to propose a pathway to explain the relationship. Methods: We analyzed a sample of 2143 older individuals (60 years of age and over) from 49 distritos of the Municipality of Sao Paulo, Brazil. Bayesian multilevel logistic models were performed with poor self-rated health as the outcome variable. Results: Income inequality (measured by the Gini coefficient) was found to be associated with poor self-rated health after controlling for age, sex, income and education (odds ratio, 1.19; 95% credible interval, 1.01-1.38). When the practice of physical exercise and homicide rate were added to the model, the Gini coefficient lost its statistical significance (P>.05). We fitted a structural equation model in which income inequality affects elderly health by a pathway mediated by violence and practice of physical exercise. Conclusions: The health of older individuals may be highly susceptible to the socioeconomic environment of residence, specifically to the local distribution of income. We propose that this association may be mediated by fear of violence and lack of physical activity. (C) 2012 Elsevier Inc. All rights reserved.
