Every 2 years, the conservation community comes together at The Society for Conservation Biology's International Congress for Conservation Biology (ICCB) to share new developments in conservation science and practice. Publication of findings presented at conferences in scientific journals adds to the permanent record and helps increase the potential impact of the work presented. However, quantitative research on publication rates for meetings relevant to conservation is lacking. For the 25th ICCB, (Auckland, New Zealand in 2011), we examined study publication rates and presenter demographics, recorded titles, number of authors, presenter affiliations, gender, country of the study region, publication status, and elapsed time between presentation and publication. Of the 980 contributions (782 talks and 198 posters), 587 (60%) were published as peer-reviewed journal articles or book chapters. Mean time to publication was 13.7 months for all presentation abstracts and 21.3 months excluding abstracts with corresponding articles that were published before the meeting. The gender breakdown of presenters was almost even (53% male, 47% female), but representation of the countries where the presenting authors were based was skewed. The political units with the most contributions were by far the United States, Australia, New Zealand, and the United Kingdom. Presenters based in 16 different English-speaking countries made up 74% of the total sample, but this did not influence the likelihood of their abstract leading to a publication. Examination of conference presenters and publication of their presentations is useful to identify biases and potential challenges that need to be addressed to make conference communications permanent and increase their reach beyond conference attendees.  相似文献

长江经济带产业分工合作现状、问题及发展对策   总被引:2,自引:0,他引:2  
在梳理长江经济带产业分工与合作现状及问题的基础上,认为长江经济带区际产业发展的互补特征鲜明,下游地区服务业发展较为完善,中上游地区特色产业突出;但也存在市场化程度发育偏低、要素流动不畅、行政区经济严重制约、中心城市产业高度偏低、区域创新能力不足等问题。还根据未来长江经济带产业分工合作的基本思路,提出应发挥下游优势产业的引领带动作用、打造行业龙头骨干企业的辐射结盟作用、加强产业园区的创新示范作用等若干对策建议。  相似文献

While there is ample – though partially contradictory – evidence regarding the effects climate change will have on various regions of the world, there is only very limited work dedicated to the analysis of different governance structures, and how these structures are likely to influence the resilience of alpine tourism systems in the face of climate change. We present an analytical framework based on network theory, and apply this to the Swiss case study destination of Engelberg, in order to deduct a number of insights for the future assessment of resilience based on the cooperation of local actors. The main aim of the paper is to come up with comparable resilience metrics based on social network analysis in order to assess the structural strengths and weaknesses of a geographically delimited tourism system in the face of climate change. Together with the action potential of the individual actors these structural properties influence the adaptive capacity of both individual actors, and the tourism system as a whole. In line with comparable studies, we identify structural strengths and weaknesses around the core-periphery distribution (centrality), subgroups (modularity) and information flows (path length). We find that the Engelberg network follows an almost ideal-typical scale-free structure and the overall cooperation rate (density) is comparable to other tourism networks. The main weaknesses of the network with regard to climate change resilience are the lacking integration of public sector actors and the relatively high number of actors in the periphery of the network.  相似文献

While transboundary waters are widely advocated to be best managed at the basin level, practical experience in transboundary waters at the basin vis‐à‐vis other scales has not been systematically examined. To understand past experiences in transboundary water management at alternate scales, this paper: (i) determines the relative abundance of water treaties at different scales and (ii) elucidates how transboundary water law varies according to the scale to which it applies. The paper developed a scale typology with six groups, and systematically applied it to stratify transboundary water treaties. Treaty contents were then compared across scales according to the following set of parameters: primary issue area, temporal development, and important water management attributes. Results of this work reveal: (i) treaties tend to focus on hydropower and flood control at smaller scales, and organizations and policies at larger scales; (ii) a temporal trend toward treaties concluded at larger scales; and (iii) a higher proportion of treaties is at larger scales in Africa and Asia than in Europe and the Americas. These findings suggest that smaller scale cooperation may constitute a more constructive scale in which to achieve development‐oriented cooperation. Further, scope may exist to complement basin scale cooperation with cooperation at smaller scales, in order to optimize transboundary water management. In the context of basin‐wide management frameworks, Africa and Asia may benefit from greater emphasis on small‐scale transboundary water cooperation.  相似文献

长三角地区大气污染治理取得一定成效,然而空气质量改善逐渐进入瓶颈期和攻坚期,大气污染治理战略需要从宏观层面系统谋划。本文系统分析了近10年来长三角区域经济、能源、产业、交通的发展状况和趋势,结合区域大气污染物浓度水平的演变,分析了大气污染与经济社会发展的耦合关系。结合当前区域空气污染的空间分布差异以及经济能源交通结构的内在差别,识别了大气污染的区内差异特征及关键制约因素。在此基础上,从能源结构和产业结构调整、交通结构优化、分区施策、深化治理等角度,为深化区域大气污染联防联控,持续改善大气污染问题提出了政策建议。  相似文献

现有城市地理研究主要基于重力模型、客货流网络和连锁模型等方法刻画城市网络。这些方法或是仅仅基于假设而可能与事实不符,或是数据难以获取,或是过于强调城市间的等级关系。通过引入合作专利数据,探索更加真实、平等的城市网络衡量方法。基于对长江经济带城市间创新联系的实证分析,发现目前城市间的创新联系以公司间(尤其是总部-分支机构间)合作为主;城市间创新联系存在非对称性和空间差异;实际创新联系与重力模型估算的创新联系存在正相关关系,但是相关系数不高;城市间创新联系的规模-位序符合Zipf定律,且存在两个无标度区;城市间创新联系受空间距离、行政级别、产业结构相似程度等影响,反映了距离衰减定律、行政区经济和产业链分工等规律对城市创新联系的解释力。  相似文献
