摘要：With this issue, Law and Contemporary Problems initiates a new practice of offering occasional "mini-symposia" on topics which deserve treatment, but may not fill an entire issue. The topics we have chosen certainly deserve treatment. The questions of policy posed by the prospect of additional urban growth in the eighties demand far more thoughtful attention than they have yet had. The relevance of an examination into the control of political and ideological dissent is manifest as we contemplate world events of the past year. We are pleased to offer these two brief symposia. We will introduce others from time to time in future issues. David Lange
