The Trump administration has worked to restrict the People's Republic of China's ability to manufacture and acquire semiconductor chips since 2018. Caught in the crossfire of this burgeoning tech war is Taiwan, which is home to Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest semiconductor chip manufacturer. With the United States banning companies that use U.S. technology in their chip manufacturing process from doing business with Huawei, TSMC can no longer do business with the Chinese tech company, one of its most important clients. Until the Trump administration announced the license restriction on Huawei, TSMC had managed to walk the fine line of doing business with both China and the United States, without riling either. This article argues that the TSMC example is indicative of how great power competition between the two countries will play out for the foreseeable future. TSMC has announced that it will build a new factory in Arizona as it faces Chinese firms poaching its employees and Chinese actors hacking its systems and code for trade secrets—all actions demonstrating how great power competition will play out for tech dominance. Avoiding direct live-fire conflict, China and the United States will work to restrict the other's actions and development by forcing important tech companies, such as TSMC, into picking a side.  相似文献

The Biden administration faces the opportunity to reset U.S. policy towards Africa and possesses a variety of tools to use in doing so, including traditional diplomacy, economic statecraft, development assistance, and military engagement. With the increased militarization of U.S. foreign policy over the past few decades, there is an unfortunate tendency to default to military engagement when confronted with even remote threats to U.S. national security interests, and Africa is no exception. With vital security interests in Africa, it can be argued that military engagement should be limited in its application and targeted to those situations that do not lend themselves to solution through traditional diplomacy or development assistance.  相似文献

The purposes of this essay are to describe how federal research and development policy has altered authority relationships and to suggest a new concept of legitimacy in accord with the changed conditions. Research and development (R and D) creates an indeterminate future. Thus, the politics of research and development incorporates an apparent contradiction : political leadership demands that jobs be done which require creative and unpredictable actions on the part of private organizations, while it also demands that contractors be held responsible for fulfilling goals efficiently, avoiding deleterious secondary consequences, and refraining from abuses of power. The paradox can be resolved by creating norms of responsibility that allow for judgments on how a job is done rather than what is to be done. New institutions for technological assessment to check on unintended consequences of projects and citizen review boards to estimate the quality of life engendered by projects may provide such norms of responsibility.  相似文献

Analyses of public policy are rooted in the economic theory of the private sector. How relevant is this approach to the public sector? Specifically, where the organization is generally viewed as a controlled variable it often exhibits the characteristics of an independent variable working to constrain the feasible solution space. An illustration of this phenomenon is discussed, using a state rehabilitation agency as the case in point. Conclusions of an analysis based mainly on maximizing the economic value of return on investment conflicted with the agency professional values of individualized client service. This external/internal value conflict led to the apparent inability of the agency to implement the study conclusions in the near term. The substance of this conflict is seen as the main problem facing many public administrators. Recognition of economic values as but one element of public agency analysis is suggested as an approach superior to sole concentration on maximization of the return on public investment. By taking a broader view, the analyst may be able to encourage more rapid implementation of his recommendations.  相似文献
