Ireland Hallo plus management accounting

[rafapak]

Hi guys. I am new here and would like to say 'hallo ' to everybody. I try to learn basics of managerial accounting . I am looking for sources that deal with modern concepts in managerial accounting. I also like reading articles written by researchers who discuss usefullness of managerial accounting and often criticize concepts like standard costing etc. Do you know guys any internet sources where people who know the subject talk about strengths and weaknesses of managerial accounting ?
