Post‐Watergate critics of the American presidency have directed much attention to the problem of controlling the White House staff. This paper argues that their proposals have ignored an implicit lesson contained in the Brownlow Report of 1937 and that it is unrealistic to build the Cabinet and department secretaries into any model of white House staff functions, particularly as a constraint mechanism on the staff. Such proposals understate the political role of the staff and approaches to reform must search for a political rather than an institutional response. 相似文献

AbstractIn an attempt to escape British hegemony, the Welsh established a Patagonian colony in 1865, in what is now the Chubut Province of Argentina. The historical struggles the immigrants faced upon settling the land are rooted in the landscape and commemorated in different versions of Patagonian regional history through provincial museum narratives that serve as a method of solidifying Welshness in Chubut. Contemporarily, the local tourism industry constructs the Welsh as the first settlers in the region, while minimally representing predecessor groups like the indigenous communities or Spanish colonials. Curiously, the representation of these other heritage communities throughout heritage displays actually serves to bolster the Welsh ‘first-place’ claims over the region. These tensions are seen throughout community-based museums in the region that assert a locally rooted hybrid identity by acknowledging local historical diversity, while simultaneously recalling and emphasising the [Welsh] homeland heritage. This paper explores how ‘first-places’ can be a source of symbolic conflict, while simultaneously serving as a dynamic, heritage construction mechanism. This research investigates how the Welsh diaspora negotiates its identity through the mobilisation of heritage, to make claims about the Chubut Province as a symbolic Welsh first-place, as well as broader Argentine heritage. 相似文献

Policies adopted by the United States government between 1987 and 1993 regarding high definition television (HDTV) were made primarily by the Federal Communications Commission (FCC). A brief effort by members of Congress and their bureaucratic and industrial allies to link HDTV to broader industrial policies was thwarted by the George Bush Administration between 1988 and 1990. The FCC's policies with respect to simulcasting and digital signals reflected the concern of that agency to protect the interests of consumers, broadcasters, and electronics manufacturers. The first two interests traditionally were protected by the FCC, whereas the protection of electronics was somewhat unusual and was influenced by perceptions of declining United States competitiveness. In addition, United States policymaking in this area depended strongly on the framing effect of policies adopted in Japan and Western Europe. 相似文献

David Rindos' coevolution theory remains the most comprehensive application of Darwinian theory to issues of prehistoric agriculture evolution. While his theory has drawn attention, there has been a lack of subsequent development of the application of Darwinian theory to prehistoric agricultural evolution. Combining Sewall Wright's shifting balance theory of evolution with aspects of Rindos' coevolution theory provides important new insights into the processes of crop transmission between regions. Using these theories, a model is developed for the adoption and subsequent evolution of maize agriculture in the Eastern Woodlands of North America. 相似文献
