Studies on the Type Selection of the Filling and Emptying System of Yingpan Lock on Wujiang River

Yingpan lock is the highest single level lock at present in China with a working head of 36.5m.This paper presents a regulation tank lock scheme and the water saving lock scheme to settle the valve hydraulics problem caused by high water head.By analyzing and comparing of the general single level lock,the regulation tank lock and the water saving lock,it is concluded that not only the recommended water saving lock can satisfy the design and the correlated operation requirements,reduce the valve work head by a half to simplify value hydraulics problem,but the water saving is possible at least by 48.6% in one ship passage through the lock.     

Introduction: Natural resources and ethnic conflicts in Asia Pacific

Abstract: The papers in this special issue are the product of a comparative interdisciplinary workshop on ‘Natural Resources and Violent Ethnic Conflicts in the Asia Pacific Region’ held in Honolulu, Hawaii, 18–20 March 2005. The workshop brought together scholars who study conflicts between ethnic groups and those who study conflicts over natural resource claims in order to examine the interplay of resources and ethnicity and to seek answers to the question of why violence occurs in some cases and not in others. Both sets of scholars agreed on some points but disagreed on others. They agreed that ethnic and resource grievances occur not so much out of objective deprivation but out of ‘relative deprivation’ when groups compare their situation with others, to the past, or to future expectations. They both stressed the role of democratic processes in alleviating resource competition and ethnic conflicts – but they did this in different ways. The perspectives and solutions offered by these papers sum to a deeper and more contextualised understanding of the cause of conflict and to mutually reinforcing solutions for resolving them.

A Corporate Geography of Canada: Insights into a Multi‐Jurisdictional Model of Corporate Governance

Comparative corporate governance has long focused on national models of corporate governance with particular attention paid to the balance of influence between divergent path dependence and convergent global market forces. Within this debate, the Canadian model of corporate governance has received little attention and has long been assumed to be an extension of the U.S. model. An analysis of the corporate geography of Canada demonstrates that the path‐dependent forces of Canada's resource‐dependent economic development remain a principal determinant in contemporary corporate Canada. Continued resource dependence in combination with a system of asymmetric federalism has led to a distinctively multi‐jurisdictional model of corporate governance. As corporate interests are provincially distinct because of the heterogeneous distribution of natural resources and markets across Canada, this model may lead to provincial lock‐in and an associated degree of managerial entrenchment.     

About the Synthesis Method of Planar Multilink Mechanisms Based on Genetic Algorithm

This paper discusses the method of synthesizing planar multilink mechanisms based on GA. The pivotal technology is coding, creating population, account fitness, genetic operation and defining population size. This method does not require initial mechanisms and can search for plural appropriate mechanisms simultaneously. It is efficient about the non-linear problem. As an example, configuration of 4-bar planar mechanisms is decided in a practical application. It can be used the synthesis of 6-bar or more bar planar mechanisms as well.
