Institutional challenges for policy-making and fisheries advice to move to a full EAFM approach within the current governance structures for marine policies

The European Union is aiming to implement an Ecosystem Approach for the management of all human activities in the marine environment, hereunder the fisheries sector. Since the last reform of the Common Fisheries Policy in 2013, several analyses have highlighted the barriers and challenges to this aim. Despite the claim that much of the framework to support the implementation of an EAFM in Europe is in place, the findings point out to deterrent features within the governance system. Beyond the overall policy framework, this paper explores the implementation of the multiannual multispecies management plans as one of the real moves towards Ecosystem Approach to Fisheries Management. This is carried out on the basis of two case studies that address the design of multiannual multispecies management plans for the Baltic Sea and for the Atlantic Pelagic fisheries. The analyses strengthen with empirical evidences our understanding of the challenges ahead including, among others, an institutional gap between fisheries and environmental policy frameworks resulting in a limited integration of broader environmental concerns in one of the proposed plan and the standoff between decision-makers that delays the adoption and use of proposed management plans and creates frustration for the involved agencies.     

Formation and performance of collaborative disaster management networks: Evidence from a Swedish wildfire response

Natural disasters present a multitude of entangled societal challenges beyond the realms and capacities of single actors. Prior research confirms that effective collaboration is of critical significance to address such complex collective action problems. Yet, studies rarely investigate if patterns of collaboration are appropriately aligned (‘fit’) with how different challenges (tasks) are interdependent, or how levels of fit influence collective action performance. We develop a set of hypotheses specifying what constitutes a good fit between collaborative networks and task interdependency. Using unique empirical data from the response to a major wildfire in Sweden, we examine how individual actors select collaboration partners and tasks during the formation the collaborative crisis response network. Then we test if levels of fit in the established network influence performance. We show that patterns of actor and task interdependency influence the formation of collaborative networks and that a good fit seems to be associated with more effective collaboration. Our data even suggest that a good fit is more important for performance than actors’ prior crisis management experience and level of professionalization. Further, we show that actors only partially engage in actor-task configurations conducive to high performance. Our study probes the limitations of simplified accounts of collaborative disaster management by enabling more precise and theoretically informed empirical inquiries regarding the mechanisms that shape the structure and performance of collaborative networks.     

明代中国人环球测绘《坤舆万国全图》——兼论《坤舆万国全图》的作者不是利玛窦

通过对详细的地理地名考析,结论是《坤舆万国全图》并非意大利传教士利玛窦根据欧洲世界地图翻译绘制,该地图的地理测绘不是1602年完成,而是1430年左右,即郑和第六次大航海之后。该地图的欧洲部分是1400年以前的地理,中国部分为1430年左右,部分美洲却是1800年以后欧洲人才知道的,与西方公认的地理大发现历史严重冲突。卫匡国的《中国新地图集》不可能是他在中国9年内完成,证明经纬度、球形投影等技术是明代中国人发明的地图绘制技术,不是"西学东渐"。此外,其他明代文化文物在美洲遗存等旁证有力支持地图论据,证明明代中国人比哥伦布先抵美洲,《坤舆万国全图》是中国文献,用现代地图学技术测绘,明代中国人是15世纪世界地理大发现和现代地图学的真正先驱。     

1556年陕西华县大地震形变遗迹及华山山前断裂古地震研究

华山山前断裂带晚第四纪以来具有明显的新活动,沿断裂带及其两侧分布有最新断层崖,基岩裂缝、黄土裂缝、山体崩(滑)塌体等众多的地震形变和破坏遗迹,华山山前断裂带应是1556年华县8级地震的发震断层。 从本文提供的一个古地震剖面分析,华山山前断裂带全新世以来可能发生过四次大地震,其重复间隔约2000—2500年     

昆仑山与汶川强烈地震对青藏块体东北缘地壳运动及应变积累的影响

充分应用GPS、区域水准、跨断层等地形变观测资料, 借助非震负位错反演, 结合地震活动, 综合研究2001年11月14日昆仑山Ms8.1级地震对青藏块体东北缘地壳运动与应变积累的影响。通过分析笔者认为, 青藏块体内部Ms8.1级巨大地震能量释放产生的扰动应力场对NE向主压背景应力场的调制作用, 导致块体边界构造区域地壳差异运动和应力应变状态发生变化。其中, 对阿尔金断裂东段与祁连山断裂带西段的应变积累状态反映减缓为主的影响, 而对祁连山断裂带中东段则反映促进应变积累为主的影响。这种影响是一定时期、一定程度的。近期青藏块体东北缘区域应力场处于昆仑山、玉门、民乐等地震后的恢复状态。而由2008年5月12日汶川Ms8.0地震后有限的GPS、跨断层短水准观测资料, 可推测汶川地震对甘川交界东段-甘川陕交界区应变积累状况一定程度促进影响。

Fine structure of seismotectonics in western Shillong massif,north east India

The epicentral tract of the great Assam earthquake of 1897 of magnitude 8·7 was monitored for about 6 months using an array of portable seismographs. The observed seismicity pattern shows several diversely-oriented linear trends, some of which either encompass or parallel known geological faults. A vast majority of the recorded micro-earthquakes had estimated focal depths between 8–14 km. The maximum estimated depth was 45 km. On the basis of a seismic velocity model for the region reported recently and these depth estimates we suggest that the rupture zone of the great 1897 earthquake had a depth of 11–12 km under the western half of the Shillong massif. Four composite fault plane solutions define the nature of dislocation in three of the seismic zones. Three of them show oblique thrusting while one shows pure dip slip reverse faulting. The fault plane solutions fit into a regional pattern of a belt of earthquakes extending in NW-SE direction across the north eastern corner of the Bengal basin. The maximum principle stress axis is approximately NS for all the solutions in conformity with the inferred direction of the Indian-EuroAsian plate convergence in the eastern Himalaya.
