current research paper is to delve into the employee-organization relationships as an effective factor on organizational citizenship behavior. the employee-organization relationships involve two dimensions: perceived organizational support and organizational identity. job autonomy is a moderator variable between the employee-organization relationships and organizational citizenship behaviors. t...

The No-Wait Job Shop (NWJS) considered here is a version of the job shop scheduling problem where, for any two operations of a job, a fixed time lag between their starting times is given. Also, sequence-dependent set-up times between consecutive operations on a machine can be present. The NWJS problem consists in finding a schedule that minimizes the makespan. We address here the so-called Opti...

Multi-site parallel job schedulers can improve average job turn-around time by making use of fragmented node resources available throughout the grid. By mapping jobs across potentially many clusters, jobs that would otherwise wait in the queue for local resources can begin execution much earlier; thereby improving system utilization and reducing average queue waiting time. Recent research in th...

In hadoop, the job scheduling is an independent module, users can design their own job scheduler based on their actual application requirements, thereby meet their specific business needs. Currently, hadoop has three schedulers: FIFO, computing capacity scheduling and fair scheduling policy, all of them are take task allocation strategy that considerate data locality simply. They neither suppor...

OBJECTIVE   To identify key workplace demands and resources for nurses working in very remote Australia and measure levels of occupational stress in this population. METHODS   The study used a cross-sectional design, utilising a structured questionnaire. SETTING   Health centres in very remote Australia. RESULTS   Nurses working in very remote Australia experience significantly higher lev...

[Purpose] The purpose of this study was to examine the musculoskeletal pain of care workers and investigate its effect on their job satisfaction. [Subjects and Methods] Subjects were 87 care workers working at C elderly care service center in P region. The average age of men was 62.5 ± 3.4 years and that of women was 57.3 ± 2.7 years. The 'Guidelines for Risk Factor Survey on Tasks with Musculo...

The recent effort to define middleware capable of supporting real-time applications creates the opportunity to raise the level of abstraction presented to the programmer. We propose that proportion/period is a better abstraction for specifying resource needs and allocation than priorities. We are currently investigating techniques to address some issues that are restricting use of proportion/ p...

Main characteristics of desktop grids are the large number of nodes and their heterogeneity. Application speedup on a large-scale desktop grid is limited by the heterogeneous computational capabilities of each node, which increase the synchronization overhead, and by the large number of nodes, that results in the serial fraction dominating performance. In this paper we present an innovative tec...

We investigate an application of Probabilistic Latent Semantics to the problem of device usage analysis in an infrastructure in which multiple users have access to a shared pool of devices delivering different kinds of service and service levels. Each invocation of a service by a user, called a job, is assumed to be logged simply as a co-occurrence of the identifier of the user and that of the ...

DaimlerChrysler is a typical IT user rather than an IT producer. We try to base our application systems development on the integration of existing components rather than on custom made solutions. This is part of our effort to limit the number of different technologies within the company. Otherwise they would build up a huge pile of legacy. In our daily work as a strategic IT department this mea...
