This research extends the role incongruity analysis of employment-related gender bias by investigating the role of dispositional and situational antecedents, specifically political ideology and the salience of cues to the traditional female gender role. The prediction that conservatives would show an anti-female candidate bias and liberals would show a pro-female bias when the traditional femal...

background: this study was done to assess the use of traditional/complementary and alternative medicine (tm/cam) during pregnancy and the reasons behind it from the mother’s perspective. materials and methods: in a cross-sectional study, 919 pregnant mothers attending at prenatal care units of governmental health centers recruited through a multistage sampling and completed a self-report questi...

BACKGROUND In the past decade, the changing labor market seems to have rejected the traditional standards employment and has begun to support a variety of non-standard forms of work in their place. The purpose of our study was to compare the degree of job stress, sources of job stress, and association of high job stress with health among permanent and fixed-term workers. METHODS Our study sub...

In order to contribute to higher levels of job satisfaction, job involvement and productivity, a match or fit should be established between the dominant career anchor associated with a specific occupation and that of the employee. A career anchor is an individual's set of self-perceived talents, abilities, motives, needs and values that form the nucleus of one's occupational self-concept. Psych...

Flexible job shop scheduling problem (FJSP) is an extended traditional job shop scheduling problem, which more approximates to real scheduling problems. This paper presents a multi-objective genetic algorithm (GA) based on immune and entropy principle to solve the multi-objective FJSP. In this improved multi-objective GA, the immune and entropy principle is used to keep the diversity of individ...

Grid computing aggregates heterogeneous resources for executing resource intensive applications of science and engineering. Grid scheduling is a complex problem (NP-hard) to map existing tasks to accessible storage and computational resources to utilize them in the optimistic manner. In this article, we have analyzed the grid scheduling problem, the process of job scheduling, challenges and app...

Material handling tasks in the job shops have to be coordinated with manufacturing operations in order to efficiently utilize the production resources and to reduce the accumulation of work-in-process inventory. This paper extends the traditional job shop scheduling problem by incorporating the scheduling of the material handling tasks. It provides a generic definition and a network model for t...

A two-stage stochastic programming model is formulated for a distributed scheduling problem with scenario tree structure. The model allows independent and self-interested job agents to request resources in an asynchronous fashion. Rather than an exact starting time, the central agent gives a time window for one coming job immediately. The final schedule is made based on the total weighted tardi...

This paper investigates the impact of the introduction of new restrictive permanent contracts on the perceived job security of the workers in Spain. The perceived job security is strongly influenced by the characteristics of individuals and their distribution within groups. Comparing heterogeneous groups could make the traditional DID estimator biased. To address this issue I combine the propen...

We study problems of scheduling n unit-time jobs on m identical parallel machines, in which a common due window has to be assigned to all jobs. If a job is completed within the due window, then no scheduling cost incurs. Otherwise, a job-dependent earliness or tardiness cost incurs. The job completion times, the due window location and the size are integer valued decision variables. The objecti...
