Inibidores de corrosão são largamente utilizados na prevenção de corrosão em operações de estimulação em poços de petróleo. Investigações teóricas e experimentais detalhadas de vinte e três compostos incluindo aminas, derivados de tiouréia e álcoois acetilênicos foram realizadas para estimar a sua eficiência na inibição de corrosão do aço 22% Cr (de estrutura austeníticoferrítica; duplex) em so...

The PLS B algorithm is used as a tool to investigate the relationships among several data sets. The ,rst step of this algorithm entails an iterative procedure the convergence of which is not proved. In this paper, an alternative procedure is discussed. It achieves the same purpose and its convergence is proven. c © 2003 Elsevier B.V. All rights reserved.

Computer task performance is an essential driver of end user productivity. Recent research indicates that computer self-efficacy (CSE) is an important determinant of computer task performance. Contrary to the significant interest in understanding the role of CSE in predicting computer task performance, little attention has been given to understanding the role of personal goal (PG), which can be...

Ten years ago, Bhattacherjee proposed the information system continuance model, which received considerable attention in the literature. This study proposes an extended information system continuance model by incorporating system quality to the original model in the context of educators’ utilization of e-learning technology for conducting courses. Our proposed model is tested using a sample of ...

Although interorganizational information system can facilitate supply chain integration and supply chain agility, unintended outcomes may occur if partners possess distinct knowledge about the use of IOS. Based on Foucault’s theory of power/knowledge, institutional theory and resource dependence theory, we analyze how various power relations work together to facilitate the institutionalization ...
