Central England has previously represented a blank area for mesolithic studies. This article endeavours to correct this with the publication of the microlithic component of three prolific surface assemblages from sites on the east Warwickshire plateau. The microliths, of later mesolithic type, are described and analysed in detail, and are shown to be noteworthy for the inclusion of large numbers of inverse basally retouched points. The assemblages are placed in their English context, and the significance of their distribution discussed. 相似文献

This project is focused on the long-term constitutive elements of presidential discourse; in other words, how rhetoric helps frame and determine national identity. Seemingly innocuous, and appearing in both ceremonial and policy addresses, presidential language concerning national identity helps shape the context, and thus sets the terms for more substantive, issue-laden debates. While one cannot measure the impact of this type of rhetoric in terms of specific issues and time frames, its influence is apparent in a broader and more diffuse perspective. This research compares the public rhetoric of presidents William H. Taft and Richard M. Nixon specifically in terms of their definitions of national identity. Both Republicans, albeit with very different political contexts and time periods, exhibited marked similarities in their strategies for defining the American polity, particularly with respect to their view of the president as the national representative, the idea that the nation is a unified whole, the belief that the nation follows the greatest good for the greatest number, the belief that each citizen occupies a natural place in the hierarchy of American society, and finally, the conviction that liberty is the most important foundational value of the country. The evidence suggests that rhetorical conceptions of national identity are important over time in the United States. Enjoying a broad audience, the president has the ability to shape national debate according to which groups and issues he includes or excludes from the polity. 相似文献

ABSTRACTTourism is a well-known way of life for an increasing portion of the world's indigenous communities, and it has taken tortuous paths and undergone changes in approach and meaning.Indigenous tourism is examined here within the theoretical framework of resilience, focusing on development, communication and justification. Men and women and their perspectives on space, time and spatial relations are the crucial agents in these processes. Based on an empirical study in Québec, Canada, we show that the impact of indigenous tourism includes networks within the local community at the regional and national levels, as well as translocal networks and relationships. Communicative processes are essential for achieving resilience, communicating identity within families and the community, and giving a voice to a political project. We argue that indigenous tourism works on several geographical levels and that these levels intersect and have the potential to increase resilience if they interact. Our study supplements resilience development theory by highlighting the need to consider communities as parts of networks. It also contributes to the field of tourism research by emphasising communication on several levels. 相似文献
