Aside from its importance as a structural element of the Welfare State, health care plays a leading role in generating innovation. Despite this, the productive base of Brazil’s health care system is extremely fragile, jeopardizing both the universal provision of health care services and the country’s competitive insertion in the globalized environment. This suggests the need for a more systematic analysis of the complex relationships that exist between the technological and the social interests involved in the productive base of health care provision in Brazil. Therefore, the purpose of this article is to enhance our understanding of the productive base of health care, especially given its potential to contribute to a socially inclusive development model, which is the ultimate goal in Brazil.展开更多

While we may consider science diplomacy as simply a part of China's Reform and Opening-up policy, the fact is that even in the Kuomintang period(1925–1949) or the Maoist period(1949–1976) it was a key element of Chinese foreign relations. The targets and nature of science diplomacy were shaped by the prevailing politics and economic issues of the times. For example,the Cold War limited the breadth and depth of S&T cooperation between China and the West.Nonetheless, the People's Republic of China pursued cooperation with the Soviet Union and newly independent countries in a very steadfast manner and continues to engage with Russia and developing countries today. This article analyses the nature of science diplomacy as an element of both China's S&T development and its foreign relations. The interactions and practices at the intersection of science and foreign policy in China are manifold. In addition to providing a comprehensive overview, this article also highlights evolving trends, especially in terms of the deepening of China's linkages across the international S&T system. Finally,the article examines the recent impact of the apparent rise of techno-nationalism and how this has affected the nature of China's international S&T activities regarding Beijing's use of science diplomacy.展开更多
