AbstractTwin studies have a contribution to make to the debate concerning the foetal origins of adult disease. Twins are growth retarded compared to singletons and experience post-natal catch-up growth. However, there is no evidence that twins are at increased risk of cardiovascular disease. Studying whether discordance in size at birth within monozygotic twin pairs is predictive of discordance in later life disease should help resolve whether the association between size at birth and later disease is due to common genetic factors. Results from studies of blood pressure in childhood and adult life looking at these within twin effects are far from conclusive. There are, however, methodological problems in the interpretation of these results, not least of which is the relatively small numbers of twin pairs studied. Studies exploring the effect of zygosity and chorion type on later disease provide may provide a useful extension of the research agenda. In summary, twin studies to date have raised more questions about the foetal origins hypothesis than they have resolved.

The throngs at Woodstock, Jane Fonda in Hanoi, I Have a Dream, burning draft cards, fire in the streets--these images of the 1960s are still very much alive today. What happened to the people and principles that dominated that decade? Which leaders from those turbulent years had the most lasting effect on our lives today? How well have the principles for which those leaders fought so strongly withstood the test of time? This thought-provoking biographical dictionary allows the reader to study the leaders, both conservative and liberal, their ideals, and their enduring influence.||With major se

Originally published in 1978. When compared with socialist and communist systems in other nations, the impact of radicalism on American society seems almost nonexistent. David DeLeon challenges this position, however, by presenting a historical and theoretical perspective for understanding the scope and significance of dissent in America. From Anne Hutchinson in colonial New England to the New Left of the 1960s, DeLeon underscores a tradition of radical protest that has endured in American history—a tradition of native anarchism that is fundamentally different from the radicalism of Europe, the Soviet Union, or nations of the Third World. DeLeon shows that a profound resistance to authority lies at the very heart of the American value system.The first part of the book examines how Protestant belief, capitalism, and even the American landscape itself contributed to the unique character of American dissent. DeLeon then looks at the actions and ideologies of all major forms of American radicalism, both individualists and communitarians, from laissez-faire liberals to anarcho-capitalists, from advocates of community control to syndicalists. In the book's final part, DeLeon argues against measuring the American experience by the standards of communism and other political systems. Instead he contends that American culture is far more radical than that of any socialist state and the implications of American radicalism are far more revolutionary than forms of Marxism-Leninism.

Many scholars have argued that systemic risks of conflicts tend to increase at critical junctures of power transitions or major power shifts. This article examines the economic and military rise of China and the challenges that it both faces and poses in East Asia, especially in relation to the United States. Specifically, it connects issues of power projection and parity, trade, and interdependence, as well as international institutions and governance to underscore the need for continued economic engagement and institutional enmeshment to lessen the likelihood of militarized conflict in the region.
