_Publicity as an Instrument of Program Administration_: As an instrument of program administration, publicity may be utilized to influence or coerce conformity with a program of control, or to facilitate the servicing of agency clientele. The use of publicity as an integral part of a control program is exemplified by routine publication of that which is prohibited, as well as by disclosure designed to exact compliance with government policy by subjecting those exposed to unfavorable publicity. Section 102 of the Defense Production Act of 1950, for example, prohibits the accumulation of scarce materials in excess of personal or business needs or for purposes of speculation. The President was directed to publish either in the _Federal Register_ or elsewhere, a list of materials the accumulation of which would be unlawful.[435] Violators of this section of the law would presumably suffer from publicity about unlawful hoarding, if and when their activities became known to the federal government. More explicit, but indicative of the same intent, was an Act of July 1940 permitting the President to publish a list of persons designated as collaborators with the Axis powers. Any person so designated was prohibited from receiving military equipment or munitions for export.[436] In a proclamation of July 1941, President Roosevelt authorized compilation and publication in the _Federal Register_ of “The Proclaimed List of Certain Blocked Nationals” under the Act.[437] In statutory provisions for registration of categories of persons, or maintenance of lists of various kinds, it is difficult, if not impossible, to discern the various purposes to be served by such requirements. Thus, if the major objective of the Foreign Agents Registration Act of June 1938 was to secure for the government current information concerning persons representing foreign governments or businesses, and to impose a penalty for failure to register as a foreign agent, certainly a minor purpose was to insure that members of the public also should have this information available to them. Section 4 of the Act required the Secretary of State to retain in permanent form all statements filed under the Act, and to make them available for public examination and inspection at all reasonable hours.[438] One can hazard a guess as to what extent this publicity provision was designed to intimidate so-called foreign agents.
