This article argues that fragmented and decentralized policy making structures can generate major Policy innovation as well as can centralized structures. The fragmented committee structure of Congress is shown to facilitate innovation in the example of federal water pollution control legislation. Thorough consideration of four dimensions of costs and benefits strengthens the case for disjointed Innovation since it “promotes entrepreneurship, encourages competition, minimizes the costs of change, and promotes legitimacy….”  相似文献

Loss of a driver license places an older person in the unhappy role of a transportation dependent. This dependence weighs heavily on that person' s family; if family members are nearby, they become either the sole or primary source of transportation for their transportation-dependent parent(s). If there are no family members nearby, as occurs often in today's highly mobile society, then a major concern of that family may be their parent(s)' lack of mobility, with the parent becoming effectively restricted to home due to lack of access to adequate transportation facilities.
Most of those who are involved in the issue of driver license renewal favor keeping older drivers on the road as long as possible, rather than arbitrarily denying them the privilege to drive. But there is legitimate concern about the presence of impaired drivers on the road and accompanying safety risks. Many states address this concern by devising license renewal procedures that will cause at least some potentially unsafe drivers to be flagged and referred for reexamination.
This study evaluates the bases for referral and reexamination currently used in the state of Iowa and assesses the validity of referrals. The results of our analysis indicate that the current referral process works quite well in identifying at-risk drivers, resulting in a high percentage of suspensions or imposing additional restrictions on an existing license. Results also support policies instituted by some states using age as a criterion for more frequent license renewal–which would allow examiners to test and observe driver behavior more frequently. The choice of age 75 as a threshold is supported by these results.  相似文献

This study examines the role of photography in the Atomic Energy Commission's representation of nuclear weapons testing during the 1950s. Pictures of fireballs and mushroom clouds functioned as part of an explicit AEC strategy to reduce the public to spectators. These photographs were designed to take the place out of the landscape — unlike the contaminated places near America's nuclear proving grounds, the pages of popular magazines were not subject to radioactive fall out. The seemingly neutral observations of the camera obscured the morphologies it appeared to represent. These arguments are developed primarily in terms of the militarization of space in Nevada, including a new geography of nuclear armament; the "story" of bomb testing produced though interaction of popular media with AEC objectives; and the social-theoretical context of photography, representation, and spectacle as politically malleable processes.  相似文献

This paper assesses three sets of contributions made by planning: to economic research on the non‐profit sector, to management of non‐profit organizations, and to public policy toward the non‐profit sector. The focus is primarily on the US, but it also includes references to the literature from other areas: Western Europe, the ex‐socialist countries and the Third World.  相似文献
