The aging of the European workforce coupled with existing deficits of skilled workers in vital sectors (e.g., information and communication technology) make the attraction and retention of skilled workers a critical strategic human resource management issue. The large-scale, multi-country study reported in this article investigates the causes of voluntary turnover. The study is based on a large...

The ability to respond eeectively and eeciently to crisis is an important objective in many problem-solving domains. In this paper, we identify three central elements of crisis: threat, urgency, and uncertainty. We deene the space of competent problem solvers for crisis response through a task analysis (Newell and Si-mon, 1972). Speciically, we bound the space of problem solvers by determining ...

The main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. We were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. If such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. In addi...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...
