Practioners are From Mars and Academics are from Venus?

I read with much interest an article that appeared in a recent issue of e-magezine On Target of The Institute of Certified Management Accountants. Titled "Practitioners are from Mars and Academics are from Venus?", the article by Dr Basil Tucker from the University of South Australia discusses why, as far as research findings are concerned, there remains a wide "Research-Practice Gap". Whilst academic research may have great contribution to the real world, researchers failed to transmit their research findings effectively to the practitioners. Amongst the reasons stipulated by the article include, where academics are being: "...elitist and pretentious use of their own jargon; discussing convoluted theory; using complex statistical techniques; being excessively concerned to demonstrate familiarity with the literature and including numerous bracketed references in the text". Some food for thought... are academics and practitioners speak different languages?
