Two of the alien species that have seriously affected the other inhabitants of the ecosystem in the US and the other parts of North America include the Green crab and the zebra mussel.

Jackson et al. (2003) came up with conceptual map of international organization and human resource management in different countries. HRM as a concept emerged in the mid-1980 in the US when two models-the Harvard framework (Beer et al. 1984) and the Michigan Model (Fombrun et al., 1984) were produced.
