As my spouse pointed out, this is a way too long of a paragraph to be a mission statement.  Nonetheless, in academic terms it is about the closest you get.  I believe that the mission of BRIA was last updated in 1989 with some minor tweaks in the Hatfield years.

So without further ado:

Sponsored by the Accounting, Behavior and Organizations Section of the American Accounting Association, Behavioral Research in Accounting publishes original research about how accounting (broadly conceived) affects and is affected by individuals, organizations, and society. The primary audience is the international community of behavioral, organizational, and social researchers in accounting. Behavioral Research in Accounting seeks original empirical research (e.g., field, survey, experimental, experimental economics) in all areas of accounting. The journal also seeks to be the venue of choice for literature reviews of underlying discipline theories; methodological and methods papers; and scale validation papers that are relevant to the journal’s scope and to its readers. Behavioral Research in Accounting also encourages replications of influential behavioral articles in order to build a robust base of knowledge about the behavioral, organizational, and social aspects of accounting. The international set of editors and reviewers collectively have expertise in all the domains that the journal seeks to influence, and promises prompt and fair reviews by subject matter experts.

Now apparently my verbs and nouns do not agree and this will be corrected in due course. Otherwise, mission accomplished!!! We have a revised mission statement!
