波尔山羊卵母细胞和早期胚胎的端粒酶活性

利用端粒重复序列扩增(TRAP)法进行了山羊卵母细胞和附植前胚胎的端粒酶活性的测定;结果表明,山羊卵母细胞和早期胚胎的端粒酶活性都为阳性。TPG定量比较发现,卵母细胞的TPG最低,为25.348U;4-细胞的TPG为273.832U,至8-细胞时,TPG又降低到56.117U,随后快速升高,桑椹胚的TPG为251.111U;囊胚的端粒酶活性最高,TPG为519.46U。     

"后京都时代"与"共同而有区别的责任"原则

《京都议定书》中给予发展中国家削减温室气体排放的豁免期截止于2012年,这使得“后京都时代”国际气候制度谈判的重点不可避免地要触及到发展中国家实质性义务的承担。作为最大的发展中国家和世界上第二大温室气体排放国,中国将在这一阶段面临前所未有的压力和挑战。笔者认为,在国际立法场合,中国仍应积极主张国际法所确立的“共同而有区别的责任”原则,在坚持国家利益的同时,积极维护国际环境义务的南北平衡。     

Trade Measures and Climate Compliance: Institutional Interplay Between WTO and the Marrakesh Accords

This article examines the potential of trade measures to induce more climate-friendly policies, focusing on the relationship between global trade rules and the Kyoto climate regime. At the core of this interplay is the normative consistency of trade-related rules in the two regimes and any hierarchical relationship between them. The stronger clout of the WTO and its compulsory dispute settlement system suggest that issues involving competing claims would be referred to WTO bodies. Such bodies have so far been restrictive regarding the exceptions in WTO agreements to the general ban on embargoes and discrimination. The normative compatibility of the two regimes will also depend on their participatory interplay, specifically how they differentiate groups of actors as to rights and obligations. Non-members of WTO receive the least protection, and their vulnerability to climate-related trade measures is largely determined by their interdependence with states that consider employment of such measures. Among WTO members, the findings of a dispute settlement body would presumably differ depending on the status of the target under the Kyoto Protocol. A non-complier with Kyoto commitments would be more shielded than a non-party, because by joining the Kyoto regime a non-complier has exposed itself to regime-internal and less trade intrusive measures that should be exhausted first. A third dimension of interplay is linkage, or efforts to influence the regime interplay. To date there has only been moderate cross-agency coordination, but considerable attention is paid within each regime, including in the Millennium Round of trade negotiations, to the desirability of avoiding conflict between them.     

The Future Climate Regime: A Regional Comparison of Proposals

This paper compares and clarifies differences revealed in proposals from different regions on a future multilateral climate regime, after the year 2012. More than 100 articles in English were collected, categorized according to the lead authors region, and then reviewed to identify the general tendencies of each region. Proposals on emission allocation rules were the most popular in Europe, while rules related to international emissions trading dominated proposals from the United States. Few articles came from other Annex I countries, but these generally provided only the most basic aspects of a future regime. Meanwhile, concerns for equity and the relevance of any new regime in terms of sustainable development were clear in proposals from non-Annex I countries. Differences among regions were considered to be a reflection of current circumstances in each authors region. The capacity and culture of authors in some regions were considered to be other possible factors in differences. The paper concludes that recognition of regional background that formulate respective preferences and concerns regarding a future climate regime will be important to help reach a multilateral agreement in future official negotiations.     

试论俄罗斯不批准《京都议定书》的原因和法律后果——以《气候变化框架公约》第九次缔约方会议为例

在<气候变化框架公约>第九次缔约方会议上,由于俄罗斯仍然拒绝批准<京都议定书>,致使议定书仍不能生效.俄罗斯拒绝批准议定书的主要原因是本国的"经济效益"重于温室效应.虽然俄罗斯不批准议定书的行为,未构成国际不当行为,从而无须承担国际责任,但该行为在很大程度上与国际法的诚意原则的基本精神相抵触,是国际社会所公认的国际背信行为.     

The Role of EU Internal Policies in Implementing Greenhouse Gas Mitigation Options to Achieve Kyoto Targets

This paper reviews the role of internal European Union (EU) policies and measures in implementing the target for greenhouse gas mitigation in the Kyoto Protocol. It starts with a discussion of the EU Burden Sharing Agreement, which distributes the target between Member States. This leads to a review of the appropriate level of implementation of policies, i.e. at the EU level or Member State level. There is a role for the flexible mechanisms of the Protocol, particularly emission permit trading, in complementing Member State policies at the EU level. The implementation is to be done against the background of three major factors which may have an important bearing on the policies: the probable long-term requirement of substantial reductions in greenhouse gas emissions a changing structure of energy markets, following liberalisation of the gas and electricity markets EU enlargement to include economies in transition with the potential for further substantial reductions in emissions.The paper concludes with a discussion of ancillary benefits of the policies that may be substantial and a summary of the position as regards the "unfinished business" of the Protocol to be discussed at the Conference of the Parties in the Hague in November 2000.     

Convergence Criteria for Participation in the Flexible Mechanisms of the Kyoto Protocol

We suggest a multi-layered system of three convergence criteria – similar to those used in the run-up to the European monetary union – that define the notion of "demonstrable progress" towards reaching the emission commitments under the Kyoto Protocol. These are the existence of an independently evaluated national emissions inventory, the level of domestic policies and measures, and the quantitative convergence of emissions towards the Kyoto target. While the first of these criteria constitutes a necessary condition for use of the Kyoto Mechanisms, the other two should determine the degree of participation allowed for any given Annex I country.     

The Role of Flexibility Mechanisms in EU Climate Strategy: Lessons Learned and Future Challenges?

The main objective of this paper is to examine the evolution of European Union (EU) climate strategy, scrutinising in particular developments in EU's views on the so-called flexibility or Kyoto mechanisms. In brief, the paper argues that there has been a gradual change in EU's views, from the role of a sceptic in the run-up to Kyoto towards becoming more of a frontrunner on emissions trading in recent years. The need to 'save Kyoto' and the protracted development of EU climate policy are highlighted as two of the most important drivers behind this process of change. This paper also discusses some of the lessons learned from international negotiations and the development of EU climate policy. Finally, and drawing upon the lessons learned, the paper explores key future challenges for the further development of EU climate strategy.     

高校体育礼仪教育的功能及其实施途径

体育礼仪主要是指人们在体育交往中所应具备的相互敬重、亲善和友好的行为规范。体育礼仪的内容主要是由内在的体育礼仪文化和外在的体育礼仪行为方式或礼仪程式等组成。通过礼仪教育可以有效地提高大学生的道德素质,增进相互之间的友谊和交流,有助于构建和谐校园。因此,学校要努力营造礼仪文化教育的氛围,加大宣传力度,塑造新型的体育人格和教育关系。
