The Oxfordian （Late Jurassic） carbonate-dominated ptatform outcropping in the Swiss Jura Mountains offers a good biostratigraphic, sequence-stratigraphic, and cyclostratigraphic framework to reconstruct changes in facies distribution at a time-resolution of 100 ka. It thus allows interpreting the dynamic evolution of this platform in much more detail than conventional palaeogeographic maps permit. As an example, a Middle to Late Oxfordian time slice is presented, spanning an interval of about 1.6 Ma. The study is based on 12 sections logged at cm-scale. The interpreted depositional environments include marginal-marine emerged ;ands, fresh-water lakes, tidal fiats, shallow lagoons, ooid shoals, and coral reefs. Although limestones dominate, marly intervals and dolomites occur sporadically. Major facies shifts are related to m-scale sea-level changes linked to the orbital short eccentricity cycle （100 ka）. The 20-ka precession cycle caused minor facies changes but cannot always be resolved. Synsedimentary tectonics induced additional accommodation changes by creating shallow basins where days accumulated or highs on which shoals or islands formed. Autocyclic processes such as lateral migration of ooid and bioclastic shoals added to the sedimentary record. CEimate changes intervened to control terrestrial run-off and, consequently, siliciclastic and nutrient input. Coral reefs reacted to such input by becoming dominated by microbialites and eventually by being smothered. Concomitant occurrence of siliciclastics anddolomite in certain intervals further suggests that, at times, it was relatively arid in the study area but there was rainfall in more northern latitudes, eroding the Hercynian substrate. These examples from the Swiss Jura demonstrate the highly dynamic and （geologically speaking） rapid evolution of sedimentary systems, in which tectonically controlled basin morphology, orbitally induced climate and sea-level changes, currents, and the ecology of the carbon

Revitalizing the Global Trading System＂ What Could the G20 Do？

引用

China & World Economy 2016年第4期24卷 34-54页

作者： bernard Hoekman Professor Robert Schuman Centre for Advanced Studies European University Institute Florence.

Since 2008, G20 leaders have repeatedly committed themselves not to resort to protectionism and to conclude WTO negotiations expeditiously. The jury is out on the extent to which they have lived up to the first promise,＂ they have failed to deliver the second. Anemic global trade growth rates since 2010 imply that trade has not been a driver of much-needed economic dynamism. This paper argues that the G20 should pursue a more ambitious trade agenda and that there is much that greater leadership by the G20 could do to reinvigorate the trading system. A first step would be to commit to concrete actions that can be implemented by individual governments on a concerted basis and that center on reducing trade costs and improving access to services for firms. The Chinese presidency should also seek to have the G20 commit to more effective monitoring and analysis of trade policy broadly defined （including subsidies and investment incentives） and the impact of the many preferential trade agreements involving China, the EU and the USA, the world＇s largest trading powers.

Why did China Benefit from a Joint Venture Policy? A Case Study of Shanghai

引用

China & World Economy 2007年第2期15卷 89-103页

作者： bernard Bishop Griffith Business School Griffith University Australia

Mandatory joint venture requirements have played an important role in many developing countries ＇foreign investment policies. However, such policies have been criticized in some of the economic literatures on the grounds that they deter investment and lead to the development of inefficient industries. A significant amount of foreign direct investment in Shanghai has been in the form of joint ventures. Yet, by many measures, Shanghai has benefited enormously. This article argues that there are three reasons to explain Shanghai＇s successful use of the joint venture for its industrial development. First, local firms and industries have had the capability and willingness to learn from joint ventures and other foreign invested firms. Second, the joint venture policy has been more likely than not to have ＂crowded in ＂ local investment rather than crowd it out. Third, investment authorities in Shanghai have had sufficient bureaucratic capacity and political insulation to prevent the joint venture policy from being manipulated by rent seekers.

Russell＇s Paradox of Predicates

作者： bernard Linsky Department of Philosophy University of Alberta Alberta T6G 2E7 Canada

Russell＇s letter to Frege of June 16, 1902 contains the famous paradox of the class of all classes which are not members of themselves as well as a second paradox of the predicates that cannot be predicated of themselves. The latter paradox arises out of Russell＇s theory of classes and class concepts in Principles of Mathematics.
