The occupational health program of a large oil refinery and petrochemical plant incorporates features which aid in the detection of pulmonary tuberculosis. The periodic examination system which includes a routine chest roentgenogram and which is conducted on all plant employees at 12-24 month intervals would be expected to discover asymptomatic cases. In addition, other cases might be found whe...

Purpose The paper discusses the new concept of ‘Multinational Investment Projects’ (MIPs) and its application in the context of international business operations in China. The petrochemical industry in China is used as the industrial context in which we investigate the interplay between the Chinese government, which encourages growth and investment activities in the sector, and the multinationa...

In this study we demonstrate an approach to replacing validated selection tests to which job applicants may have prior access. This approach, labeled construct equivalence, allows for replacing valid tests currently in use with new, experimental tests that have been shown to measure the same constructs. We demonstrated the construct equivalence approach by collecting data from over 2,000 applic...

One of the most important ways to prevent accidents is to consider safety climate or culture. Moreover, some studies suggest that behavior contributes to 86%-96% of all injuries. This cross-sectional study took place in an Iranian petrochemical company in 2010. Vinodkumar and Bhasi's safety climate questionnaire and an ergonomic behavior sampling checklist were the data collection tools. Cronba...

Many decision makers are hindered in their daily work by “unintegrated” systems which can force them to move data around between tools which are only more or less compatible. Because environmental models play an important role in environmental decision support systems, the integration of models into user-friendly integrated decision support systems is essential to the support of such users. Thi...

A polystyrene coated quartz crystal nanobalance (QCN) sensor was developed for use in the determination of a number of linear short-chain aliphatic aldehyde and ketone vapors contained in air. The quartz crystal was modified by a thin-layer coating of a commercial grade general purpose polystyrene (GPPS) from Tabriz petrochemical company using a solution casting method. Determination was based ...
