Extraordinary significance of V.V. Menner activity for effective work of the Interdepartmental Stratigraphic Committee aimed at organization of stratigraphic survey and enhancement of stratigraphic research in the country is demonstrated. As chairperson of the International Commission on Stratigraphy, he made an outstanding contribution to its structuring and transformation into fruitful international institution supervising works on all subdivisions of the International Stratigraphic Scale.  相似文献

This article reviews the types and effectiveness of marine mammal mitigation measures used during some naval activities worldwide. The three main standard methods used to mitigate the potential impacts of naval sonar sound on marine mammals are (1) time/area planning (of exercises/active sonar use) to avoid marine mammals; (2) implementation of operational procedures (e.g. ‘soft start’ - where sound levels are gradually increased over time); and (3) monitoring of animals for the purpose of maintaining an ‘exclusion zone’ around the sound source. Suggestions towards a minimum worldwide mitigation standard are made.  相似文献

Beyond Germany, Leo Waibel (1888–1951) built a distinguished reputation for his work in Africa and the Americas. Today he is remembered especially in Brazil, where he boosted the development of geography as a research discipline in the years 1946–1950. During his tenure of the chair in geography at Bonn (1929–1937), Waibel's main research preoccupation became the role of the tropics in the world economy. In early 1937, he sought research leave to make an extended field trip to Brazil. Stripped on political grounds in the same year of his chair, Waibel came to the United States, where he became the only geographer to receive help from the Emergency Committee in Aid of Displaced Foreign Scholars. He would eventually serve as one of the very limited core staff on President Franklin Roosevelt's “M” Project on migration and settlement. This paper reconstructs the context of his work in the United States, clarifying especially the nature of his collaborations with Isaiah Bowman, widely regarded at the time as the leading geographer within the United States. Waibel's correspondence from the United States, and later from Brazil, reveals an international career marked by contradictions.  相似文献

A significant landmark for British and international photogrammetry, as well as for this journal, occurred in January 2010 with the centenary of the birth of E. H. Thompson. Soldier and academic, polymath and wit, his scholarly contribution to our discipline has endured long after his too early death in 1976. So too have the vivid memories of those who worked with him or who were taught by him. This centenary tribute has been written by an author, E. H. Thompson's first cousin once removed, who has researched the Thompson family genealogy. The second author was a student and then an academic colleague of Thompson as well as being Assistant Editor of this journal for 11 years under Thompson's editorship.  相似文献

北太平洋海洋科学组织(PICES)是国际海洋交流与合作的重要平台,1992年PICES成立以来,中国海洋领域科学家积极参与PICES发起的各项科学活动,促使中国海洋人才的科研能力和国际交往能力得到有效提升。文章回顾了中国参与PICES科学活动历经的3个重要发展阶段,从初期参与到深入参与再到目前的全面参与阶段,总结了各阶段PICES中国工作取得的进展与可喜成绩;阐述了参与PICES科学活动对中国海洋科学发展的积极推动作用;对未来PICES中国工作的重点方向提出了建章立制、统筹协调、群策群力、发挥所长和加大宣传力度等展望。  相似文献

增强发展中国家能力建设是全球应对气候变化的重要前提条件,而在联合国气候变化框架公约(UNFCCC)的谈判进程中,能力建设部分一直进展缓慢。自缔约方第7次会(COP7)上确定了发展中国家能力建设框架后,能力建设的机制建设一直没有取得实质性进展。在巴黎气候变化大会(COP21)上,缔约方一致通过了《巴黎协定》。《巴黎协定》首次授权通过执行附属机构(SBI)建立巴黎能力建设委员会(PCCB)。该委员会将全面协调对发展中国家能力建设的支持,同时监管2016-2020年的能力建设工作计划,全面系统地促进和增强发展中国家应对气候变化的能力建设活动。另外,《巴黎协定》还同意建立透明度能力建设倡议(CBIT)用以增强2020年前后的机制和技术能力。随后,全球环境基金(GEF)为该倡议成立了CBIT信托基金。至此,公约下能力建设议题已经建立了相对完整的国际机制。未来议题的谈判将走向务实与细节。随着全球应对气候变化迈向一个新阶段,中国在能力建设议题的谈判上也应做相应的调整。  相似文献

Astrotomography     
Even in the new millenium, many astronomical objects cannot be resolved spatially with any available telescope. Most stars are too small and galaxies are too far away to be imaged directly or in detail in the foreseeable future. However, advances in data‐analysis techniques allow us now to create detailed indirect images using tomographic methods. These images provide unprecedented insights into fundamental processes that drive the evolution of stars and galaxies, such as accretion and magnetic‐field generation, on length scales that are of great physical importance but which are otherwise inaccessible. Here we present a collection of papers on recent progress in astrotomography, all of which were presented at Joint Discussion 09 of the XXV General Assembly of the IAU in Sydney, during July 2003. The online edition of the journal contains several illustrative movies for free download. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)  相似文献

On the occasion of the thirtieth anniversary of the United Nations Framework Convention on Climate Change, this principal supra-national institution remains paramount to the project of planetary climate planning and governance. Reflections on this anniversary should serve to recall the contestations through which this foundational institution was formed, and the delegate dynamics that continue to be reproduced in its wake. The contentious debates and political dynamics that afflicted the Intergovernmental Negotiating Committee tasked with crafting the Framework Convention on Climate Change, as well as dissension in the periphery, remain as relevant today as they were three decades ago. Reprising these dynamics through detailed historical and archival analysis, this article excavates the negotiations of the 1992 Framework Convention on Climate Change by the Intergovernmental Negotiating Committee, which met in 5 sessions during 1991–1992. The aim is to identify key fault-lines and conflicts in the lead-up to the finalization of the 1992 Convention, in order to demonstrate whose epistemic and normative commitments came to be reflected in the final outcome and to show how the legacy of this process endures to date. I seek to render visible actors and proposals peripheralized in the formation of planetary climate governance to extrapolate normative boundaries and proffer heterodox lessons from the margins.  相似文献
