Study on the planning principles of urban forest

The urban forest is the main body for the urban forestry management. There are not unified rules and standards for the planning of the urban forest yet in China. This paper discusses the planning principles of the urban forest： the priority of the ecological function, the adaptation to local condilions, the optimization in the whole system, the mutual dependence of forest and city, the culturecontinuance and recreation satisfaction, sustainable development and operability, etc. This paper takes Changsha as an example to elaborate the planning principles of the urban forest. Firstly, Changsba urban forest ecosphere is composed of the eco-garden, the round-the-city forest belt, the ecological isolation belt, the green channel, the landscape of the rivers and streams, the forest park, the biodiversity reserve and the eco-forest in suburb area. It aims to make every kind of ecological essential factors organically merge into the complex city ecosystem to build an eco-city, to strengthen the connection of wide-open space with various habitats spots, to promote resident＇s accessibility, to perfect landscape ecology, and to make full use of the ecological function of urban forest. When we construct the urban forest, we must optimize the comprehensive benefit and make the urban forest structure and the layout in the best condition in order to buiM the harmonious green city for both man and nature to realize the whole optimization of the city system by the complex functions of the urban forest in ecology, environmental protection, landscape, recreation, etc.     

Economic principles and fundamental model of the sustainable utilization of ecological resources

1. Introduction The mainstream of present economy is the green eco-economy, including green products, green production, green consumption, green market, green industry, and so on. These are the concrete demands of sustainable development for economic life. With the development of economy, society and science and technology and the increase of the population, the abundant ecological resources become more and more scarce [1]. So the quantity and quality of eco- logical resources can’t increasin…     

Earnings Quality under Rules‐ versus Principles‐based Accounting Standards: A Test of the Skinner Hypothesis / LA QUALITÉ DES RÉSULTATS SELON QUE LES NORMES COMPTABLES SONT AXÉES SUR LES RÈGLES OU SUR LES PRINCIPES: VÉRIFICATION DE L'HYPOTHÈSE DE SKINNER*

We provide preliminary evidence, consistent with Skinner (1995), that Canada's relatively principles‐based GAAP yield higher accrual quality than the United States' relatively rules‐based GAAP. These results stem from a comparison of the Dechow‐Dichev (2002) measure of accrual quality for cross‐listed Canadian firms reporting under both Canadian and U.S. GAAP. However, we document lower accrual quality for Canadian firms reporting under U.S. GAAP than for U.S. firms, which are subject to stronger U.S. oversight, reporting under U.S. GAAP. The latter results suggest that stronger U.S. oversight compensates for inferior accrual quality associated with rules‐based GAAP. Consistent with the positive effect of Canada's principles‐based GAAP and the offsetting negative effect of Canada's weaker oversight, we find no overall difference in accrual quality between Canadian firms reporting under Canadian GAAP and U.S. firms reporting under U.S. GAAP. Our results imply that (1) policymakers who wish to compare the effectiveness of oversight across jurisdictions must control for the GAAP effect; and (2) accounting standard‐setters who wish to compare the effectiveness of principles‐ versus rules‐based GAAP must control for oversight strength.     

Are Asian Sovereign Wealth Funds Different?

Sovereign wealth funds have become a prominent feature of the international financial landscape. However, legitimate concerns have been raised about these funds. Many of those concerns can be addressed via increased accountability and transparency by the funds. The Santiago Principles are a good start in doing so. My sovereign wealth funds scoreboard points to areas where these Principles can be improved. At the same time, the OECD effort to address concerns from the host‐country side has not resulted in the erection of new barriers to that form of cross‐border investment, but the OECD failed to reverse the creeping financial protectionism of the past decade. Because of their size and the source of their funding, some Asian funds stand out. As a result, those funds will be held to a higher standard of accountability and transparency.

How Safe Are the Harbors?

Abstract

With the growth of e-commerce has come the need for businesses to provide protection of personal, private data collected from internet users and consumers. The United States has favored a policy of industry self-regulation, while the European Union (EU) has responded to its consumer demands for privacy protection regulations and enforcement. Faced with the critical need for a middle ground, the US has proposed “Safe Harbor Privacy Principles” as a means of compromise with the EU. This article explores the market context of the Safe Harbor Principles, the European reaction, and the probable impact on businesses.

主权财富基金投资法律环境新变化——评IMF“圣地亚哥原则”

主权财富基金在国际金融发展中的地位日益重要，由于其具有浓厚的政府控制特质，因而受到投资接受国的严格监管。为避免严格监管引发金融保护主义、阻碍跨国投资，由各方共同参与制定的国际规则将成为平衡彼此利益的有效手段，国际货币基金组织（IMF）组织制定的“圣地亚哥原则”是这一进程中最受瞩目的成果之一。对主权财富基金投资法律环境新变化的考察与研究无疑会对我国主权财富基金具有启发与借鉴意义。     

赤道原则-国际金融公司政策的延伸

赤道原则是国际项目融资的环境与社会的最低行业标准。它的制订与执行由国际金融公司主导,它的核心内容基本上援引了国际金融公司的政策和指南,国际金融公司环境与社会政策的评审结果关乎着赤道原则的命运。国际金融公司也帮助赤道银行培训赤道原则专家,国际金融公司的政策与实践直接影响赤道原则的性质。它把自己定位为开发性金融规则的提倡者,是由于现实因素的推动,客观上提高了银行的公众形象,也提高了国际金融公司自身的形象。
