Peripheral ERA is a pitching statistic created by the Baseball Prospectus team. It is the ERA you would expect a pitcher to have given his park-adjusted hits, walks, strikeouts, and home runs allowed. Unlike Voros McCracken's DIPS, hits allowed are included. PERA doesn't attempt to eliminate the effect of luck on batted balls away from ERA, instead attempting to account for good (or bad) luck in the combinations of hits, walks, home runs, and strikeouts. A lower PERA than EqERA (adjusted ERA) may indicate poor luck which may even itself out in the future, leading to a lower EqERA despite no change in quality of pitching.
This kind of situational statistical study is one of the core concepts of sabermetrics.
Thorn and Palmer specifically identify a number of ways in which Weaver's strategies reflected sabermetric principles in their books, which identify the eras in which Weaver's "God Bless the Three Run Homer" philosophy was in fact statistically justified.
The computer game Earl Weaver Baseball had artificial intelligence based on Weaver's statistical principles.
This marked the beginning of an era in which many articles and books about Indian-White relations were published which made moral judgments condemning Whites.
Sometimes these terms are not meant to refer to natives of the British Isles, but to people who have descended, at least in some good degree, from natives of these regions, or to people who were natives of the British Isles who migrated to the New World and became or didn't become "naturalized" citizens.
In the era of the American Revolution (also known as the War of Independence, etc.), the British in America split up to some fair extent into British (Loyalists or Royalists)) and Americans (rebels, or as the winners say, patriots), along with those who were neutral, undecided, wavering, or with divided loyalties.
