America and Iran have not had diplomatic relations for two decades. In May 1997 the election of Mohammad Khatami, a reformist, to Iran's presidency provided an opening for a cautious rapprochement. Khatami advocated people-to-people contacts between the two nations to break the ice, and the United States agreed. After critically evaluating the idea of people-to-people contacts and discussing the role of the large Iranian diaspora in America as a mediator between the peoples of the two countries, this article examines the sports diplomacy that resulted from Khatami's initiative. It concludes with a comparison with the ping pong diplomacy that heralded the thaw in US-Chinese relations.  相似文献

This article explores the hypothesis that people in less democratic nations will use the Internet newsgroups devoted to those countries as a relatively ‘safe’ form of political discussion and even protest. Also, it is expected that nationals of those countries living overseas will use these newsgroups to more openly discuss politics in those nations than they could otherwise do so. Before turning to a content analysis of the messages posted in non‐United States Usenet groups, the number of these groups and the levels of political discussion in them are quantified. The article quantifies the international usage of the Usenet as a first attempt to find some patterns in this usage that may be politically motivated. After all, many pundits imagine that the Internet will become the vaunted ‘global village’ and source of ‘grass‐roots democracy’, and not merely in the United States. An examination of the content of about 2500 messages in 41 Usenet groups then follows, with a view to establishing the following: how many messages are explicitly political; how many are in opposition to the current government; how many are pro‐government; whether they primarily serve as alternative sources of news; whether they are attempts to recruit people in the subject country and around the world into some sort of political action; and whether richer nations are more likely to have higher levels of discussion in their newsgroups than poorer ones. The findings conclude that newsgroups devoted to countries with lower levels of democratization have a much higher percentage of anti‐government messages than the newsgroups about nations that are more democratic.  相似文献

The public trust doctrine provides protection of public access to resources, such as navigable waterways, protected under the public trust. The doctrine has evolved over time to protect natural resources such as tidelands, submerged waterbeds, wildlife, and climate change. Juliana v. United States is a groundbreaking trust case that moves the application of the trust to the management of climate-change regimes. Although the doctrine has been criticized as a façade, forestalling real recourse for change, it can be used to show standing for current and future generations. Accordingly, Juliana outlines how this doctrine is not just evolutionary it is also revolutionary.  相似文献

Only the best manufacturers will remain competitive in today's challenging environment. Any manager involved with developing new products knows the excitement, complexity, and risk of this unpredictable undertaking. Based upon findings from four world class manufacturers of medical imaging technology in Japan and the United States, this article presents a new organizing framework for integrating external information into the NPD process. The findings are particularly timely in an era when manufacturers are vulnerable to intense global competition. The article concludes with several implications for managers involved in the new product development process.  相似文献
