Trees as technology: planting shelterbelts on the Great Plains

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.     

The Pendulum of Congressional Power: Agenda Change,Partisanship and the Demise of the Post-World War II Foreign Policy Consensus

Many scholars contend that Congress rarely matters in the realm of foreign policy. The source of this collective impotence is often explained by the weaknesses in congressional institutions vis-a-vis the president, as well as a general inability to respond effectively to a dynamic international political environment. We contend that the debate over congressional activism has not adequately addressed the role of agenda change. We analyze all roll call votes in the House of Representatives relating to the international affairs agenda between 1953 and 1998. We find that presidents have become significantly more likely to stake out positions on economic and trade issues as compared to other international issues. We also observe that presidential positions in the realm of foreign policy are increasingly characterized by interparty and interinstitutional conflict. While this increased conflict has dramatically decreased the president's ability to successfully pass executive priorities in foreign affairs more generally, presidential success on economic and trade issues has witnessed a significantly greater decline. We infer from these results that changes to the foreign policy issue agenda represent one important factor that has affected not only the incentives for political parties to participate actively, but also the willingness of Congress to challenge the president in the foreign policy debate.Asked one day whether it was true that the navy yard in his district was too small to accommodate the latest battleships. Henry Stimson (chair of the House Naval Affairs Committee early in the century) replied, 'That is true, and that is the reason I have always been in favor of small ships.'1Carriers have been, are and will be for the foreseeable future an absolutely essential part of our deterrence force…2John Warner, senator from Virginia, home state of Newport News Shipbuilding     

New Strategies for an Old Medium: The Weekly Radio Addresses of Reagan and Clinton

Charisma is one of the most common explanations for the success of political leaders in obtaining the support of the mass public. Yet authors employing the concept typically begin their analyses by simply assuming the presence of charisma, foregoing more rigorous analyses, including the consideration of alternative explanations for public appeal. Thus, charisma becomes a post hoc attribution, a residual category of explanation that is difficult to evaluate objectively. This article examines the concept of charisma in the context of the American presidency by testing for its consequences, including presidents obtaining unusually high levels of support, support from unusual sources, or especially intense and committed support, or successfully leading public opinion on matters of public policy. I particularly focus on the best-case tests of John F. Kennedy and Ronald Reagan. Unable to find systematic evidence of some special form of leadership that we might characterize as "charismatic," I conclude that the concept of charisma is neither salvageable analytically nor helpful empirically.     

Mechanics,thermodynamics and locomotive design: Analytical methods and the classic form

The railway machine‐ensemble was brought to the classical condition by applying rational management, and associated techniques, which were developed by F.W. Taylor, F.B. Gilbreth, and H.L. Gantt. These methods identified the Stephenson‐Goss archetype, operated on the Common User system, as the ideal form of locomotive for the steam operated railway. It is argued that when a system is brought to the classical condition it usually approaches Design Impasse, and obsolescence.

The application of rational methods to the machine‐ensemble is related to the creative, derivative, and synthetic traditions of engineering design.     

In Retreat from Excellence: The Single Six-Year Presidential Term

Analysis of the effects of the single, six-year term proposal by assessing its probable impact on presidential tenure in the past reveals that it would have reduced the tenure of highly regarded presidents who were relatively successful in dealing with Congress and increased the tenure of presidents with lackluster reputations and limited success in congressional relations. Thus, by inference, the adoption of this widely-touted institutional reform might undermine rather than strengthen presidential leadership in American politics.     

Chert sources and distribution patterns in the stone age of West Finnmark,North Norway: A preliminary view

A preliminary analysis of chert sources and distribution patterns in west Finnmark is described. Three small quarries and a fourth possible source area are situated on the coast west of Alta. Petrographic and geochemical analyses lend tentative support to the proposition that chert from these coastal sources was distributed inland during the Late Stone Age and Early Metal Periods.
