A longitudinal study of moderately professionalized technical workers was conducted to test a vanety of investment model (Farrell & Rusbult, 1981) predictions concerning the determinants of job satisfaction, job commitment, and turnover In general, greater job satisfaction resulted from high job rewards and low job costs, whereas strong job commitment was produced by high rewards, low costs, po...

The objective of this paper is to re-evaluate the effect of the 1985 ”Employment Services for Ex-Offenders” (ESEO) program on recidivism, in San Diego, Chicago and Boston. The initial group of program participants was split randomly in a control group and a treatment group. The actual treatment (mainly being job related counseling) only takes place conditional on finding a job, and not having b...

This paper focuses on the problem of scheduling a set of independent jobs with setup times and job splitting, on a set of identical parallel machines such that total tardiness is minimized. In this study, it is assumed that a job can be split into sub-jobs and these sub-jobs can be processed independently on parallel machines. Because the problem is NP-hard, a memetic algorithm (MA) is proposed...

This paper studies the problem of scheduling jobs in a two-machine open shop to minimize the makespan. Jobs are grouped into batches and are processed without preemption. A batch setup time on each machine is required before the rst job is processed, and when a machine switches from processing a job in some batch to a job of another batch. For this NP-hard problem, we propose a linear-time heur...

BACKGROUND Information on job strain exposure among Malaysian workers in multinational companies is limited. AIMS To investigate the prevalence and factors associated with high job strain among office workers of a multinational company in Malaysia. METHODS A cross-sectional study was conducted in November 2007 among 470 eligible workers. Respondents self-administered the Job Content Questio...

PURPOSE The aim of this study was to investigate the relation between anthropometric variables and total race time including split times in 184 recreational male Ironman triathletes. METHODS Body mass, body height, body mass index, lengths and circumferences of imbs, thicknesses of skin-folds, sum of skin-fold thicknesses, and percent body fat were related to total race time including split t...

Big Data processing is generally defined as a situation when the size of the data itself becomes part of the computational problem. This has made divide-and-conquer type algorithms implemented in clusters of multi-core CPUs in Hadoop/MapReduce environments an important data processing tool for many organizations. Jobs of various kinds, which consists of a number of automatically parallelized ta...

In parallel computation we often need an algorithm for dividing one computationally expensive job into a xed number, say N , of subjobs, which can be processed in parallel (with reasonable overhead due to additional communication). In practice it is often easier to repeatedly bisect jobs, i.e., split one job into exactly two subjobs, than to generate N subjobs at once. In order to balance the l...

This paper uses a unique firm level data base of traditional and newly established private enterprises to investigate gross job flows and labour demand in the transition period in Slovenia. We find that job destruction dominates job creation in the early years of transition, but later in the transition job destruction diminishes. The excess job reallocation rate, a measure for restructuring, is...
