Research has generally revealed only a weak link, if any at all, between victimization-related experiences and job performance. Drawing on the commonly used conservation of resources perspective, we argue that such inconsistent evidence in the organizational literature stems from an over-focus on personal resources at the expense of considering the role of social resources. Victimization is an ...

background and purpose: clinical competence has four essential components: knowledge , physical exam , problem solving and communication skill .the communication skill isn’t an optional extra in medical training but it is a core clinical skill. this study is performed in order to determine whether communication skill training for internal medicine and infectious disease residents improves their...

The increase in wage inequality since 1980 in the United States has been more pronounced in larger cities, even after accounting for di¤erences in the composition of the workforce across locations. Using Census of Population and Census of Manufacturers data aggregated to the local labor market level, this paper examines the importance of changes in the factor bias of agglomeration economies, ca...

In this paper Hybrid Ant Colony Optimization (HAntCO) approach in solving Multi–Skill Resource Constrained Project Scheduling Problem (MS–RCPSP) has been presented. We have proposed hybrid approach that links classical heuristic priority rules for project scheduling with Ant Colony Optimization (ACO). Furthermore, a novel approach for updating pheromone value has been proposed, based on both th...

a common problem arising in project management is the fact that the baseline schedule is often disrupted during the project execution because of uncertain parameters. as a result, project managers are often unable to meet the deadline time of the milestones. robust project scheduling is an effective approach in case of uncertainty. upon adopting this approach, schedules are protected against po...

Large-scale projects often have several activities which are performed by subcontractors with limited multi-resources. Project scheduling with limited resources is one of the most famous problems in the research operations and optimization cases. The resource-constraint project scheduling problem (RCPSP) is a NP-hard problem in which the activities of a project must be scheduled to reduce the p...

objectives: a large number of congenitally deaf children are born annually. if not treated, this will have destructive effects on their language and speech development, educational achievements and future occupation. in this study it has been tried to determine the level of language skills in children with cochlear implants (ci) in comparison with normal hearing (nh) age-mates. methods: test of...
