We develop an affinity model for longitudinal categorical data in which the number of categories is large and we apply the technique to 20 years of labour market data for a contemporary cohort of young adult workers in the USA. The method provides a representation of the underlying complexity of the labour market that can then be augmented to include covariate effects. These can be understood a...

OBJECTIVES Sickness presenteeism (SP) is postulated as workers' response to their general state of health; hence, SP is expected to affect workers' future health. In the present study, we examined the reciprocal relationship between SP and health in response to job stressors, with specific reference to psychological distress (PD) as workers' state of health. METHODS We conducted mediation ana...

This project investigated the incidence, interplay, and impact of gender- and sexuality-based harassment, as experienced by lesbian, gay, bisexual, and queer (LGBQ) employees in higher education. Unlike much queer empirical research, participants in this study were residents of noncoastal regions of the U.S. that are predominantly White, rural, and conservative (i.e., "red states"). They comple...

BACKGROUND Research from outside the medical field shows that leadership behaviours influence job satisfaction. Whether the same is true for the medical training setting needs to be explored. The aim of this study was to investigate the influence of residents' overall appreciation of their supervisor's leadership and observation of specific supervisor leadership behaviours on job satisfaction. ...

The purpose of this study was to determine the degree to which employers support the use of e-portfolios by job applicants and attempted to answer the following additional questions: (1) What e-portfolio features do employers prefer? (2) What eportfolio delivery systems do employers prefer? and (3) What are types of companies prefer that applicants use e-portfolios when applying for a job? A sa...

In this paper, we proposed the fuzzy multi-job and multi-company workers assignment problem with penalty. Our purpose is obtaining the optimal solution the assignment problem, where n jobs are assigned to m workers (m>n), each job must be assigned to one and only one worker and each worker could be received one job or do not receive any job. Furthermore, there are k company where each worker be...

Multi-Processor interconnection with varying speed is a great attempt in massive parallel processors. Such types of distributed cluster along with heterogeneous behavior will requires vast amount of scheduling efforts. Complexity increases as scheduler has to detect dynamic characteristics of the processors. Parallel schedulers are implemented in cluster technology for job assignment and placem...

We consider a two-stage tandem queue with two parallel servers and two queues. We assume that initially all jobs are present and that no further arrivals take place at any time. The two servers are identical and can serve both types of job. The processing times are exponentially distributed. After being served, a job of queue 1 joins queue 2, whereas a job of queue 2 leaves the system. Holding ...

Article history: Received 18 July 2011 Available online 6 March 2012 Applying a multiple-mediator model, we examine the mediating effect of three types of career-specific parenting behaviors: lack of engagement, support, and interference, on the relationship between paternal job insecurity and youths' career self-efficacy. Data were collected from a sample of undergraduate students and their fa...

There is a trend to use computing resources in a way that is more removed from the technical constraints. Users buy compute time on machines that they do not control or necessarily know the specifics of. Conversely this means the providers of such resources have more freedom in allocating them amongst different tasks. They can use this freedom to provide more, or better, service by reallocating...
