The future for beef

Beef is a fast-growing, multi -billion dollar industry today in the United States. And the outlook for tomorrow is most favorable. Beef consumption has increased by 26 pounds per capita during the past 15 years, hitting an all-time high of 90 pounds per capita in 1962. During the same period quality has improved, and now. beef commands even wider consumer acceptance than in the mid-1940\u27s. New technology has lowered production and marketing costs. But even a strong, healthy industry must be sensitive to change--and take advantage of new opportunities for growth and improvement. The beef industry is no exception.https://lib.dr.iastate.edu/card_reports/1016/thumbnail.jp

Southeast Asia and the Politics of Vulnerability

The economic and political crises that have recently engulfed the countries of Southeast Asia provide a stark reminder of just how difficult the challenge of sustained regional development remains. In retrospect, the hyperbole that surrounded the 'East Asian miracle' looks overblown, and testimony to the manner in which rhetoric can outstrip reality, especially in the minds of international investors. Certainly, some observers had questioned the depth and resilience of capitalist development in Southeast Asia, but in the years immediately prior to 1997 such analyses tended to be in the minority. Now, of course, it is painfully obvious that much of Southeast Asia's economic and political development was extremely fragile. When seen in historical context, this outcome should not have been surprising since the countries of modern Southeast Asia, both as independent nations and as colonies of various imperial powers, have been highly vulnerable to the actions of powerful external political and economic forces. This paper will examine the economic bases and the political consequences of this vulnerablity, both domestically and at a regional level. I argue that the recent crisis has served as an unwelcome reminder of just how constrained, dependent and vulnerable the Southeast Asia region's development prospects remain, a situation that is exacerbated by, and which contributes to, domestic political crises

Ligand-Receptor Interactions

The formation and dissociation of specific noncovalent interactions between a variety of macromolecules play a crucial role in the function of biological systems. During the last few years, three main lines of research led to a dramatic improvement of our understanding of these important phenomena. First, combination of genetic engineering and X ray cristallography made available a simultaneous knowledg of the precise structure and affinity of series or related ligand-receptor systems differing by a few well-defined atoms. Second, improvement of computer power and simulation techniques allowed extended exploration of the interaction of realistic macromolecules. Third, simultaneous development of a variety of techniques based on atomic force microscopy, hydrodynamic flow, biomembrane probes, optical tweezers, magnetic fields or flexible transducers yielded direct experimental information of the behavior of single ligand receptor bonds. At the same time, investigation of well defined cellular models raised the interest of biologists to the kinetic and mechanical properties of cell membrane receptors. The aim of this review is to give a description of these advances that benefitted from a largely multidisciplinar approach

Re-thinking Regionalism: Europe and East Asia in Comparative Historical Perspective

Regionally-based processes of political and economic integration, security cooperation, and even social identification have become increasingly important and prominent parts of the international system. Nowhere have such processes gone further than in Western Europe. Somewhat surprisingly, similar patterns of regional integration have been steadily developing in East Asia - a region many observers consider unlikely to replicate the European experience. What are the factors that encourage regional political cooperation and economic integration? Are there common forces encouraging such outcomes in very different geographical areas and at very different moments in history? This paper uses an historically grounded comparative approach to examine the historical pre-conditions that underpinned the formation of the European Union, and then contrasts them with the situation in East Asia today. While the overall geopolitical and specific national contexts are very different, the East Asian experience may ultimately generate relationships and structures that are more like the European Union's than some of the sceptics imagine
