This paper introduces Clustera, an integrated computation and data management system. In contrast to traditional cluster-management systems that target specific types of workloads, Clustera is designed for extensibility, enabling the system to be easily extended to handle a wide variety of job types ranging from computationally-intensive, long-running jobs with minimal I/O requirements to compl...

The general evidence supporting the use of work sample tests (good criterion related validity, positive applicant reaction and job preview capability) is reviewed, limitations are also noted. The extent to which work sample tests may be used to limit adverse impact in selection is reviewed and the extent to which work sample tests may be used to complement other selection instruments, in partic...

The concept of procedural utility assumes that agents do not only receive utility from outcomes, but also attach an independent value to the procedures that lead to these outcomes. This paper analyzes whether the preferences that underlie procedural utility are homogeneous, using the case of independence at the workplace. I exploit the event of German reunification to assign preferences for ind...

background burnout is a common syndrome associated with job stresses in the health sector personnel, especially female nurses. objectives the aim of this study was to investigate burnout and its association with types of capital among female nurses in educational hospitals of kermanshah university of medical sciences. patients and methods this was a retrospective cross-sectional study. the stud...

This paper develops a consistent set of worker flow data for The Netherlands, based on the availability of actual time series and a number of additional assumptions, between all essential states in the labour market: employed, unemployed and out of the labour market. Furthermore, we also construct, based on the same principle, series of job flows, where job creation, job destruction and job rea...

This paper reviews modern genetic algorithm based approaches for solving job shop scheduling problems Genetic algorithms represent one of the most popular and mostly used metaheuristic methods applied for solving many optimization problems within last few decades. Job shop scheduling represents one of the hardest combinatorial optimization problems where number of possible schedules drastically...

In this paper we analyze a scheduling problem where each job j E J is executed in dependence to a branching forest. We have a set of processor types P with a price c(p) for each processor of type p E P. A job j processed on a processor of type p E P has an execution time e(j,p) E N. Given a deadline d E N, we consider the problem to select a minimum cost set of processors (allowing an unlimited...

This study examined the buffering effects of 2 types of organizational support--instrumental and informational--on the relationships between workplace violence/aggression and both personal and organizational outcomes. Based on data from 225 employees in a health care setting, a series of moderated multiple regression analyses demonstrated that organizational support moderated the effects of phy...

Mass production of goods with customer specific features is mostly carried out on production lines. Job-dependent processing times in the lines individual work zones necessitate line sequencing, in order to use the line well to capacity. In this contribution, a two-step-method allowing fast sequencing even for huge numbers of jobs and product types is presented. The knowledge about the line cha...

Job Market Signaling and Employer Learning This paper extends the job market signaling model of Spence (1973) by allowing firms to learn the ability of their employees over time. Contrary to the model without employer learning, we find that the Intuitive Criterion does not always select a unique separating equilibrium. When the Intuitive Criterion bites and information is purely asymmetric, the...
