The activities associated with the governance of a country or other area, especially the debate or conflict among individuals or parties having or hoping to achieve power. A political system is a framework which defines acceptable political methods within a given society. History of political thought can be traced back to early antiquity, with seminal works such as Plato's Republic, Aristotle's Politics and the works of Confucius. Politics is exercised on a wide range of social levels, from clans and tribes of traditional societies, through modern local governments, companies and institutions up to sovereign states, to the international level.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
