The present work investigates using non-blocking and minimum-blocking Java library classes as a basis for improving performance of parallel bidirectional search on a multiple-instruction multiple-data (MIMD) processor. The approach represents individual states as minimum-size, immutable objects. It uses a work queue to distribute states-for-expansion among worker threads, and it uses two sets f...

Many theoretical models of labor market search imply a tight link between worker flows (hires and separations) and job gains and losses at the employer level. We use rich establishment-level data to assess several theoretical models and to study the relationship between worker flows and jobs flows. Hires, quits, and layoffs exhibit strong, highly nonlinear relationships to employer growth rates...

Purpose – The purpose of this paper is to explore the relationship between the extent of total quality management (TQM) implementation and organization performance, and the moderating effect of co-worker support and organization support on the TQM/performance relationship. Design/methodology/approach – A questionnaire survey was developed and distributed to a sample of firms selected from the m...

In this work, 3D visualization of a work place by means of a computer-made 3D-machine model and computer animation of a worker have been performed. By visualization of 3D characters in inverse kinematic and dynamic relation with the operating part of a machine, the biomechanic characteristics of worker's body have been determined. The dimensions of a machine have been determined by an inspectio...

We examine the interaction between risk (uncertainty) and production efficiency in determining pay-performance sensitivity in optimal executive compensation. Particularly, we show that the risk-incentive trade-off is exacerbated (attenuated) as production efficiency increases when the efficiency level is greater (less) than the level of compensation risk. This result suggests that the optimalit...

Envy is a universal emotion and often is considered to be socially undesirable. This emotion has been relatively ignored in organizational behavior research. In this study, we focus on the impact of leader member exchange on envy. We also investigate moderating effects of perceived co-worker similarity and equity sensitivity in the relationship between leader member exchange and envy. Building ...

OBJECTIVES This study aims to investigate the relationship between the total injury experience rate and socioeconomic status based on the fourth Korea National Health and Nutrition Examination Survey (KNHANES). METHODS By analyzing data from the fourth KNHANES conducted from 2007 to 2009, we estimated the injury experience rate according to socioeconomic status, including the occupational cha...

Workplace accidents involving machines are relevant for their magnitude and their impacts on worker health. Despite consolidated critical statements, explanation centered on errors of operators remains predominant with industry professionals, hampering preventive measures and the improvement of production-system reliability. Several initiatives were adopted by enforcement agencies in partnershi...
