Comparison of the deterministic and fuzzy approaches in HR planning
Supplying required human resource is one of the strategic goals of an organization. Therefore, organizations plan and predict the required human resources in order to prevent this problem. Present study using practical approach seeks to assist organizations to achieve their various goals in human resources planning. The designed model in this study clarifies vague, inaccurate, and fuzzy exp...

متن کاملRing Nebulae around Massive Stars throughout the HR Diagram
Massive stars evolve across the HR diagram, losing mass along the way and forming a variety of ring nebulae. During the main sequence stage, the fast stellar wind sweeps up the ambient interstellar medium to form an interstellar bubble. After a massive star evolves into a red giant or a luminous blue variable, it loses mass copiously to form a circumstellar nebula. As it evolves further into a ...
متن کاملA spectroscopic study of the magnetic CP - star HR 1094 ?
The chemically peculiar star HR 1094 has been investigated with respect to its chemical composition and the magnetic influence on its stellar spectrum. By using spectral lines slightly affected by the field v sin i was determined to be ≤ 17 km s −1. The iron-group elements as well as chlorine and the heavy elements platinum, gold and mercury show an overabundance compared to the sun. The analys...
متن کاملHR Metrics and Strategy
The idea that an organization's people represent a key strategic resource is widely accepted. The business press is filled with examples of top executives proclaiming how important it is to engage people's minds and spirits in the quest for competitive advantage There is also mounting scientific evidence that certain "bundles" of "high-performance" work practices (e.g., performance-contingent p...
