1 Blood group A individuals have the A antigen on the surface of their RBCs, and blood serum containing IgM antibodies against the B antigen. 2  Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.
Devolution is the statutory granting of powers from the central government of a sovereign state to govern at a subnational level, such as a regional, local, or state level. It is a form of decentralization. Devolved territories have the power to make legislation relevant to the area. Devolution differs from federalism in that the devolved powers of the subnational authority may be temporary and ultimately reside in central government, thus the state remains, de jure unitary.
The meaning of decentralization may vary in part because of the different ways it is applied. Concepts of decentralization have been applied to group dynamics and management science in private businesses and organizations, political science, law and public administration, economics and technology. Devolution transfers all responsibility for decision-making, finance and implementation of certain public functions to the sub-national level, such as a regional, local, or state government. 2  Divestment, also called privatization, may mean merely contracting out services to private companies.
