Audiences,metaphors, and the Persian Gulf war

This paper examines George Bush's Persian Gulf war addresses as a representative anecdote of Bush's campaign to build an international military coalition. The paper argues that in war rhetoric international audiences should be considered. A theorization of the international audience is offered. George Bush's public speeches are then analyzed as they use two metaphoric clusters. The SAVAGE cluster is used to justify a response to Iraq's 1990 invasion of Kuwait. The CIVILIZATION cluster is used to justify an American‐led military response. The metaphoric clusters are shown to be persuasive to the international audience as they are adopted and recirculated by this audience. Conclusions and implications of the interaction of these two metaphoric clusters for future war rhetoric are offered.     

Collecting the Revolution: New Directions in Research

ABSTRACT

This essay reports on the latest efforts to assess the collections of materials relating to the Russian Revolution held in the Hoover Institution and the New York Public Library (NYPL). The first section reviews the presentations made by Bertrand Patenaude, Michael Herrick, and Robert Davis during the roundtable “Collecting the Revolution” at the annual meeting of the Association for Slavic, East European, and Eurasian Studies in November 2017. The second presents additional information documenting the development of NYPL’s and Hoover’s collections located in The Wisconsin State Historical Society Archive and the Archive of the Russian State Library.     

The Post-Cold War Metamorphosis of the Davis Center for Russian and Eurasian Studies Library

ABSTRACT

In May 2005, the staff and collections of the library of the Davis Center for Russian and Eurasian Studies were formally brought together with the libraries of three other internationally focused centers, under the aegis of the Social Sciences Program of Harvard College Library. The article summarizes the move and earlier history of the Davis Center library.

The effectiveness of subsidies revisited: Accounting for wage and employment effects in business R&D

The present paper investigates the effectiveness of public subsidies on business enterprise research in a panel of OECD countries. We contribute to the literature by explicitly distinguishing between the effects of a subsidy on R&D employment and expenditure, thereby accounting for a potential increase in scientists’ wages. We employ instrumental variable regressions to address endogeneity problems of the subsidization. The results indicate that subsidies are effective in generating additional research expenditure. Expenditure for business research increases by roughly 20% more than employment. We take this as evidence that subsidies may raise scientists’ wages given standard production functions.     

基于率失真优化的视频编码研究（英文）

率失真优化技术在视频优化编码中起着重要的作用,广泛地应用于宏块模式决策,优化量化等编码模块中。本文将率失真优化编码与码率控制结合起来进行研究,通过对率失真关系的分析,提出了基于率失真优化的复杂度可分级码率控制算法,并根据缓冲区操作模型的位分配约束条件调整码率控制的位分配过程,从而使得该算法能够在达到码率控制的同时也能取得较高的编码效率,并能保证缓冲区不会发生溢出,然后结合场景变换、图像内容分类等主观质量问题研究,提出一种恒定质量码率控制编码算法。
