    The effect of changing gravity and weightlessness of vasopressin control systems

    Get PDF
    An immunoassay to determine the effects of changing gravity and weightlessness on vasopressin control system is discussed. Seven extracts from persons known to have inappropriate ADH syndrome secondary to pulmonary oat cell cancer were examined. The extracts had previously been subject to bioassay in rats. The intent of the examination was to determine if the vasopressin content could be confirmed immunologically. The results compared favorably with the values obtained by biological assay

    American Multinationals and American Economic Interests: New Dimensions to an Old Debate

    Get PDF
    The 2008 election rekindled debate about whether US multinationals shift technology across borders and relocate production in ways that might harm workers and communities at home. President Obama now pledges to end tax breaks for corporations that ship jobs overseas. The preoccupation about the behavior of American multinationals takes three forms: (1) that US-based multinational corporations may follow a strategy that leads them to abandon the home economy, leaving the workers and communities to cope on their own with few appealing alternatives after the multinationals have left; (2) worse, that US-based multinational corporations may not just abandon home sites but drain off capital, substitute production abroad for exports, and "hollow out" the domestic economy in a zero-sum process that damages those left behind; and (3) worst, that US-based multinational corporations may deploy a rent-gathering apparatus that switches from sharing supranormal profits and externalities with US workers and communities to extracting rents from the United States. Each contains a hypothetical outcome that can be compared with contemporary evidence from the United States and other home countries. This working paper shows that multinational corporations do not locate their operations in a zero-sum manner that favors host economies at the expense of the home economy. The two-way flow of inward and outward investment does not create an outcome that can be reasonably characterized in any way as "hollowing out" the home economy. The evidence consistently shows that the expansion of MNC operations abroad and the strengthening of MNC operations in the home country are complementary, and the answer to the counterfactual--would the home country be better off, or would workers in the home country be better off, if home-country MNCs were prevented from engaging in outward investment?--is indisputably negative. Making it more difficult to engage in outward investment would not strengthen the home economy in the United States. Quite the contrary, placing obstacles in the way of US multinationals using the United States as the center for conducting their global operations would leave them, their suppliers, their workers, and the communities where they are located worse off and less competitive in the world economy.International investment, foreign direct investment, multinational corporations, exports

    Three Threats: An Analytical Framework for the CFIUS Process

    Get PDF
    Under what conditions might a foreign acquisition of a US company constitute a genuine national security threat to the United States? What kinds of risks and threats should analysts and strategists on the Committee on Foreign Investment in the United States (CFIUS), as well as their congressional overseers, be prepared to identify and deal with? This study looks at three types of foreign acquisitions of US companies that may pose a legitimate national security threat. The first is a proposed acquisition that would make the United States dependent on a foreign-controlled supplier of goods or services that are crucial to the functioning of the US economy and that this supplier might delay, deny, or place conditions on the provision of those goods or services. The second is a proposed acquisition that would allow the transfer to a foreign-controlled entity of technology or other expertise that might be deployed in a manner harmful to US national interests. The third potential threat is a proposed acquisition that would provide the capability to infiltrate, conduct surveillance on, or sabotage the provision of goods or services that are crucial to the functioning of the US economy. This study analyzes these threats in detail and considers what criteria are needed for a proposed foreign acquisition to be considered threatening. Ultimately, the vast majority of foreign acquisitions pose no credible threat to national security on these grounds.

    Foreign Manufacturing Multinationals and the Transformation of the Chinese Economy: New Measurements, New Perspectives

    Get PDF
    What is the relationship between foreign manufacturing multinational corporations (MNCs) and the expansion of indigenous technological and managerial technological capabilities among Chinese firms? China has been remarkably successful in designing industrial policies, joint venture requirements, and technology transfer pressures to use FDI to create indigenous national champions in a handful of prominent sectors: high speed rail transport, information technology, auto assembly, and an emerging civil aviation sector. But what is striking in the aggregate data is how relatively thin the layer of horizontal and vertical spillovers from foreign manufacturing multinationals to indigenous Chinese firms has proven to be. Despite the large size of manufacturing FDI inflows, the impact of multinational corporate investment in China has been largely confined to building plants that incorporate capital, technology, and managerial expertise controlled by the foreigner. As the skill-intensity of exports increases, the percentage of the value of the final product that derives from imported components rises sharply. China has remained a low value-added assembler of more sophisticated inputs imported from abroad--a “workbench” economy. Where do the gains from FDI in China end up? While manufacturing MNCs may build plants in China, the largest impact from deployment of worldwide earnings is to bolster production, employment, R&D, and local purchases in their home markets. For the United States the most recent data show that US-headquartered MNCs have 70 percent of their operations, make 89 percent of their purchases, spend 87 percent of their R&D dollars, and locate more than half of their workforce within the US economy--this is where most of the earnings from FDI in China are delivered.Foreign Direct Investment, International Investment, China, Multinational Corporations, Exports

    High voltage electron microscopy of lunar samples

    Lunar pyroxenes from Apollo 11, 12, 14, and 15 were investigated. The iron-rich and magnesium-rich pyroxene specimens were crushed to a grain size of ca. 50 microns and studied by a combination of X-ray and electron diffraction, electron microscopy, 57 Fe Mossbauer spectroscopy and X-ray crystallography techniques. Highly ordered, uniform electron-dense bands, corresponding to exsolution lamellae, with average widths of ca. 230A to 1000A dependent on the source specimen were observed. These were?qr separated by wider, less-dense interband spacings with average widths of ca. 330A to 3100A. In heating experiments, splitting of the dense bands into finer structures, leading finally to obliteration of the exsolution lamellae was recorded. The extensive exsolution is evidence for significantly slower cooling rates, or possibly annealing, at temperatures in the subsolidus range, adding evidence that annealing of rock from the surface of the moon took place at ca. 600 C. Correlation of the band structure with magnetic ordering at low temperatures and iron clustering within the bands was studied
