Knowledge integration in sustainability governance through science-based actor networks

Understanding how science, technology and innovation can best help to accelerate progress in achieving sustainable development remains a grand challenge for researchers and practitioners. In the context of the global consultation process for preparing a post-2015 Sustainable Development Agenda, various science-based actor networks have emerged, aiming to translate research into political decision-making and to inform transformations towards sustainability. Over the last years, these networks seem to have taken an ever-growing role in structuring the science-policy interface in global sustainability governance. The question arises, however, how they understand and organize ‘scientific knowledge integration’ in sustainability politics.This study offers a structured comparison of twelve global science-based actor networks engaged in the implementation of the Sustainable Development Goals. It shows that these networks use two types of strategies to foster scientific knowledge integration in sustainability governance. A new framework emerges, in which each strategy corresponds to two main approaches of scientific knowledge integration: The entrepreneurial strategy generally seeks to advance advice-oriented and solution-oriented knowledge processes, while assessment-oriented and learning-oriented processes in scientific knowledge integration are mainly promoted through a mediating strategy.     

Flooding of Sinking Creek,Garretts Spring karst drainage basin,Jessamine and Woodford counties,Kentucky, USA

Tashamingo Subdivision in Sinking Creek karst valley, a tributary of the Garretts Spring drainage basin in Jessamine and Woodford counties, Kentucky, was flooded in February 1989. To determine the cause of flooding, the groundwater basin boundary was mapped, discharge data were measured to determine intake capacity of swallets, and hydrologic modeling of the basin was conducted. Swallet capacity was determined to be limited by the hydraulic parameters of the conduit, rather than by obstruction by trash. Flooding from a precipitation event is more likely, and will be higher, when antecedent soil moisture conditions in the watershed are near saturation. Hydrologic modeling shows that suburban development of 20 percent of the southeast basin will cause a small increase in flood stage at Tashamingo Subdivision.

晚石炭世腕足动物古生物地理区形成机制—环境控制论

晚石炭世腕足动物地理分布以及散布过程受环境控制。在控制腕足动物地理分布的诸多环境因素中，温度是首要因素，板块构造亦具巨大影响。在腕足动物散布过程中，温度的驱赶作用，洋流的携带作用，海浸与海退等环境因素犹如传送带一样，将腕足动物（幼虫）携带到能满足其生态需要的生存、繁衍场所。腕足动物具快速散布的潜能，该潜能的发挥取决于环境。由于研究的类别以及其所处地质年代不同，各种环境因素控制作用的主次地位可能变更。这就是环境控制论的主要内容。

外力扰动加剧与澜沧—耿马大地震的爆发

构造运动强烈、不断发生强震的云南地壳,可能经常有部分区域处于不稳定状态,外力也正是在此基础上才得以对地震活动显示出明显的调制效应。1988年11月6日澜沧—耿马7.6级、7.2级大地震前的大量观测资料表明,云南地区,特别是澜沧—耿马附近地区又再次出现了类似1970年通海7.7级、1974年大关7.1级和1976年龙陵7.4级大地震之前,曾发生过的那种地表涝旱剧变和大气压力巨涨落现象。这种震前的外部异常扰动具有很强的重复性,在对应地震上也显示了很强的应验性,故其很有可能在云南未来7级大地震的监视预报中发挥作用。     

Geomorphology and sedimentary/biosedimentary structures of the intertidal environment along the coast of Kuwait,north-western Arabian Gulf

The coast of Kuwait can be divided into nine intertidal geomorphological subunits, of which four are found along the northern muddy shoreline and five along the southern sandy shoreline. In the north the coast is characterized by wide intertidal mudflats, bounded landward by an extensive coastal sabkha which is partly covered by sand drifts. The upper part of the intertidal environment is covered with a mixture of aeolian sands and muddy sediments of marine origin. A number of shallow tidal channels dissect the intertidal flats and small sand bars occur near the low water line. In contrast, the southern shore is characterized by relatively steep sandy beaches fronted by narrow to moderately wide rocky intertidal platforms which are partly covered by sand, bioherms, skeletal debris and algal mats. In some areas the rocky surface is dissected by numerous small gulleys and shallow channels. Multiple sand bars lying either parallel or diagonal to the shoreline are developed near the low water line. This southern intertidal environment is bounded landward by a sandy berm and a wave-cut cliff.Ripple marks are developed almost parallel to the shoreline, showing different flow directions. Energy levels are moderate to high along the southern shore, but low along the northern shore. In the south, waves induced by winds blowing mostly from the north-east and south-east form the dominant energy source, whereas tidal and wind-driven currents are the only tangible process acting along the northern shore.
