Readers will undoubtedly have been struck by the frequent use of terms and ideas drawn from a relatively small universe of macrolevel organization perspectives. All of the book's chapters, except those the two of us wrote, were produced in total independence one to the next. That there is often a common parlance and appeal to a basic body of theoretical propositions is either a remarkable coincidence or the outcome of a convergence and maturation of our thinking about macrolevel organizational behavior. We lean toward the latter argument; what we see is neither accidental nor haphazard.
