Now, we ask for your help. Can you contribute to our shared understanding on this topic? We invite you to “add value” (rather than just telling us you agree or disagree). Please add a reference, a counter- argument, an insight, a nuance. Combining the “Conversation Starter” (above) with selected reader comments (below), we will eventually produce and post a “White Paper” on this important topic. The author/host will review each submission for appropriateness and relevancy before posting.
