Shock tubes have been used successfully by a number of investigators to study the biological effects of variations in environmental pressures (1,2,3). Recently an unusually versatile laboratory pressurization source became available with the capability of consistently reproducing a wide variety of pressure-time phenomena of durations equal to and well beyond those associated with the detonation of nuclear devices (4). Thus it became possible to supplement costly full-scale field research in blast biology carried out at the Nevada Test Site (5,6) by using an economical yet realistic laboratory tool. In one exploratory study employing pressure pulses of 5 to 10 sec duration wherein the times to max overpressure and the magnitudes of the overpressures were varied, a relatively high tolerance of biological media to pressures well over 150 psi was demonstrated (7). In contrast, the present paper will describe the relatively high biological susceptibility to long duration overpressures in which the pressure rises occurred in single and double fast-rising steps.

After the electoral reform in 1994, Japan saw a gradual evolution from a multi-party system toward a two-party system over the course of five House of Representatives election cycles. In contrast, after Taiwan’s constitutional amendment in 2005, a two-party system emerged in the first post-reform legislative election in 2008. Critically, however, Taiwan’s president is directly elected while Japan’s prime minister is indirectly elected. The contributors conclude that the higher the payoffs of holding the executive office and the greater degree of cross-district coordination required to win it, the stronger the incentives for elites to form and stay in the major parties. In such a context, a country will move rapidly toward a two-party system. In Part II, the contributors apply this theoretical logic to other countries with mixed-member systems to demonstrate its generality. They find the effect of executive competition on legislative electoral rules in countries as disparate as Thailand, the Philippines, New Zealand, Bolivia, and Russia. The findings presented in this book have important implications for political reform. Often, reformers are motivated by high hopes of solving some political problems and enhancing the quality of democracy. But, as this group of scholars demonstrates, electoral reform alone is not a panacea. Whether and to what extent it achieves the advocated goals depends not only on the specification of new electoral rules per se but also on the political context—and especially the constitutional framework—within which such rules are embedded.
