Although traditional scheduling policies for high-end parallel systems focus on minimizing average job wait time while maximizing system utilization, actual supercomputer workload traces confirm the existence of significant periods of time of low utilization. Previous work has shown that, in the context of backfilling schedulers, portions of such high-end systems can be selectively powered down...

Drawing upon the “happy-productive worker” hypothesis and Job Demands-Resources model, we examine whether expatriates’ well-being mediates association between interaction adjustment job satisfaction; this indirect effect is moderated by perceived accomplishment of organizational goals for assignment. Based on responses from 148 assigned expatriates confirmed expected influence mediation goals. ...

BACKGROUND In order to better understand the role of work environment in the earlier stages of the cardiovascular disease process, we wanted to investigate the influence of work-related psychosocial factors on preclinical atherosclerosis. METHODS Cross-sectional data was used to examine the association between psychological job demands, job decision latitude, and carotid atherosclerosis in 26...

In the last decade, various approximation approaches, such as dispatching rules, shifting bottleneck heuristic and local search methods, are proposed for the job shop scheduling problem. As one of the local search methods, taboo search provides a promising alternative for the job shop scheduling problem; however, it has to be tailored each time with respect to parameters for every instance in o...

Economic conditions at the time of entering the labour market can induce wage differentials between entry cohorts. While there exists much empirical evidence on the existence and persistence of these cohort effects, little is known about their impact on employees’ mobility behaviour. Using a large data set derived from German administrative data, this paper analyzes the determinants of job mobi...

This study examines the influence of perceived organisational support (POS) on expatriates’ cross-cultural adjustment, assignment completion and job satisfaction in sub-Saharan African context. While multinationals depend expatriates to manage their foreign subsidiaries, successful expatriation is influenced by adjustment host country’s environment. Survey responses from 229 were analysed using...

The increasing precariousness of work, its concentration among vulnerable groups, and the divide between secure, primary sector workers and the expendable army of casual and contract labour is well documented. Much less attention has been directed to the other side of precariousness – the practices that increase the costs of job loss for workers in the primary labour market. In an era of low of...

BACKGROUND Hypertension is assumed to be one of the mechanisms through which job strain (a combination of high work demands and low job control) increases coronary heart-disease risk. However, direct tests of this hypothesis are lacking. METHODS We examined whether hypertension mediated the association between job strain and incident coronary heart disease among 5630 men and 2456 women free o...
