A government is the system by which a state or community is controlled. In the Commonwealth of Nations, the word government is also used more narrowly to refer to the collective group of people that exercises executive authority in a state. In the case of its broad associative definition, government normally consists of legislators, administrators, and arbitrators. Government is the means by which state policy is enforced, as well as the mechanism for determining the policy of the state. A form of government, or form of state governance, refers to the set of political systems and institutions that make up the organisation of a specific government. Government of any kind currently affects every human activity in many important ways. For this reason, political scientists generally argue that government should not be studied by itself; but should be studied along with anthropology, economics, environmentalism, history, philosophy, science, and sociology. All governments recognize the principle that the public must be protected and served. This book focuses on concept and the relationship between the governments to public and relations. This valuable book is a '';must-read'' for all academics, practitioners, students and policymakers.
