Public
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the Öffentlichkeit or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, it has suffered in more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder.
Public Administration
Public Administration is the implementation of government policy and also an academic discipline that studies this implementation and prepares civil servants for working in the public service. As a "field of inquiry with a diverse scope" whose fundamental goal is to "advance management and policies so that government can function". Some of the various definitions which have been offered for the term are: "the management of public programs"; the "translation of politics into the reality that citizens see every day"; and "the study of government decision making, the analysis of the policies themselves, the various inputs that have produced them, and the inputs necessary to produce alternative policies."
Security
Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces. Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, and any other entity or phenomenon vulnerable to unwanted change by its environment.
System
A system is a regularly interacting or interdependent group of items forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.
Security
From that point, my universe went on crumbling; new cracks appeared all the time. I could see that the pleasant securities of childhood, all of those warm little human emotions, all of those trivial aims and purposes that we allow to rule our lives, were an illusion. We were like sheep munching grass, unaware that the butcher's lorry is already on its way. I got used to living with a deep, underlying feeling of uncertainty that no one around me seemed to share. It was rather like living on death row.
Colin Wilson in Alien Dawn, pp. 12-13 (1998)
Security
We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.
Karl Popper, The Open Society and Its Enemies (1945)
Public Administration
Liberty and good government do not exclude each other; and there are excellent reasons why they should go together. Liberty is not a means to a higher political end. It is itself the highest political end. It is not for the sake of a good public administration that it is required, but for security in the pursuit of the highest objects of civil society, and of private life.
John Dalberg-Acton, 1st Baron Acton, The History of Freedom in Antiquity (1877)
