Through the co effort of international Antarctic organizations and member countries concerned in recent years, Antarctic Data Directory Syatem(ADDS) is established as the most important basic programme for development of the international Antarctic data management system. At present, Joint Committee on Antarctic Data Management(JCADM) is responsible for organizing and coordinating the international Antarctic data management, and implementing the project ADDS.In this paper the background on Antarctic data management in time sequence and the structure of international framework are introduced, meanwhile, it is necessary to develop ADDS first of all. The ADDS mainly consists of the two principal parts: National Antarctic Data Center(NADCs) of all the party members and Antarctic Main Directory(AMD), the best available technology for creating ADDS is to make full use of International Directory Network(IDN) and adopt its Directory Interchange Formats(DIF). In the light of the above requirements, combined with Chinese specific situation, the contents, technical and administrative methods on Chinese Antarctic data management are discussed to promote our related work.展开更多

The conceptual frameworks are the theoretical accounting bases that are constituted by a set of principles that underlie as a bedrock foundation cornerstone for the development and updating of IFRSs. The existing conceptual frameworks were issued by IASB in 2010, after long years of protracted and wide consultation and joint project with the biggest American standard setter Financial Accounting Standards Board （FASB）. In year 2013, the IASB embarked on a solo project to update the conceptual framework and issued a discussion paper （DP/2013/1） to its users and stakeholder community for comments. The methodology used in this study of an extensive review of literature （secondary/primary） from the discussion paper, existing conceptual framework, and comment letters from investors, accounting, insurance, and international audit firms has been manipulated. The findings revealed that the existing conceptual framework has opposing objectives especially that of decision usefulness （future-oriented information） and concepts of ＂prudence and stewardship/accountability＂, which are deeply embedded within the framework as subsumed, but their prominence has been overshadowed and watered down by not identifying them as objectives. The finding also revealed that almost all public accounting and audit firms are advocating not only for the reinstatement of the ＂prudence and stewardship/accountability＂ but also for a clear definition of recognition, de-recognition, and measurement of statement of financial position elements （assets and liabilities） and also elements of the comprehensive income statement （revenues and expenses）, which have seriously compromised investors, public accounting profession, learning/teaching of a framework-based understanding, and the entire IFRS user stakeholder community. A recommendation for further studying the abandoned joint IASB/FASB project should be investigated in the best interest of international accounting standards convergence.展开更多

It was thus the first international treaty to endow the 2 ℃ global temperature target with legal effect.The qualitative expression of the ultimate objective in Article 2 of the United Nations Framework Conventionon Climate Change （UNFCCC） has now evolved into the numerical temperature rise target in Article 2 of theParis Agreement. Starting with the Second Assessment Report （SAR） of the Intergovernmental Panel on Cli-mate Change （IPCC）, an important task for subsequent assessments has been to provide scientific informa-tion to help determine the quantified long-term goal for UNFCCC negotiation. However, due to involvementin the value judgment within the scope of non-scientific assessment, the IPCC has never scientifically af-firmed the unacceptable extent of global temperature rise. The setting of the long-term goal for addressingclimate change has been a long process, and the 2 ℃ global temperature target is the political consensuson the basis of scientific assessment. This article analyzes the evolution of the long-term global goal foraddressing climate change and its impact on scientific assessment, negotiation processes, and global low-carbon development, from aspects of the origin of the target, the series of assessments carried out by the 1PCCfocusing on Article 2 of the UNFCCC, and the promotion of the global temperature goal at the political level.展开更多

The overwhelming natural hazards located along the belt and road bring great challenges to the success of BRI. In this framework, a 5-year international program was launched to address issues related to hazards assessment and disaster risk reduction(DRR). The first workshop of this program was held in Beijing with international experts from over 15 countries. Risk conditions on Belt and Road Countries(BRCs) have been shared and science and technology advancements on DRR have been disseminated during the workshop. Under this program, six task forces have been setup to carry out collaborative research works and three prioritized study areas have been established. This workshop announced the launching of this program which involved partners from different countries including Pakistan, Nepal, Russia, Italy, United Kingdom, Sri Lanka and Tajikistan. The program adopted the objectives of Sendai Framework for Disaster Risk Reduction 2015-2030 and United Nation Sustainable Development Goals 2030 and was implemented to assess disaster risk in BRCs and to propose suitable measures for disaster control which can be appropriate both for an individual country and for specific sites. This paper deals with the outcomes of the workshop and points out opportunities for the near future international cooperation on this matter.展开更多
