Policy Networks in Complex Governance Subsystems: Observing and Comparing Hyperlink,Media, and Partnership Networks

Methods for observing policy networks have not kept up with the development of new network analytic techniques required to understand governance in complex settings. We compare three unobtrusive methods for observing policy networks based on hyperlinks between policy actor web sites, on media reports, and on public policy partnerships. Observations of one complex local water policy arena with all three methods provide a comparison of the general as well as actor‐specific network characteristics in the three observed networks. The core network of actors observed by all methods has similar network level statistics, highly correlated relationships measured by Quadratic Assignment Procedures models, and the same significant network microstructures as measured by Exponential Random Graph Models. The full networks including actors observed by any method also exhibit similar actor‐level characteristics, although the correlations across networks are stronger for bridging capital measures than for bonding capital measures, and each method has different apparent biases. Once biases are accounted for, similarities suggest that these methods may provide useful proxies for each other and for other relationships that are more difficult or impossible to measure, particularly when combined to offset each method's biases. If so, they can extend the range of policy networks observable with limited resources across space and time.     

南诏大理国金属佛像制作工艺初探

为研究南诏大理国金属佛像的制作工艺,对部分金属佛像进行了科学分析,表明制作各种铜佛像时,主要使用失蜡铸造工艺,已使用多种金属元素作为材质,阿嵯耶观音像和其他铜像是以含砷的铜合金为特征,金质佛像的材质主要用金银合金,铸造小铜佛像则采用复杂的合金成分配比。根据铭文和绘画资料分析,这些金属佛像主要是大理本地的工匠制作。     

The Jacob Story: Between Oral and Written Modes

In this article I examine the relations between Jacob’s putative oral story and the pre-Priestly narrative. I argue that Hosea’s prophecy presents the version of Jacob's oral story related in his time and antedated by many years the composition of the story-cycle in its written form. Comparison of Hosea’s prophecy and Jacob’s narrative indicates the thorough way in which the exilic author worked the oral story he received in order to fit it to his ideological messages and religious concepts. To further examine the relations between the oral and written modes, I discuss the episode of the treaty between Laban and Jacob (Gen 31,45–54) in light of a Mari letter (A.3592). Comparison of the two episodes indicates that part of the biblical narrative rests on the oral story and other part was written by the late author. Evidently, the long process of oral transmission, the growth of the narratives in its course, and the creative reworking of the author make it impossible to either isolate the early oral layer within the present story-cycle or to date the stages of its growth in the oral process of transmission.     

世界城市网络研究的热点变迁及主题判别——基于WOS数据库的知识图谱分析

借助可视化软件,从梳理研究热点及识别研究主题两方面,厘清世界城市网络的研究脉络与核心,探索未来研究动向。研究发现：①世界城市网络研究国际合作广泛,研究热点响应迅速,经历“世界城市”与“世界体系”分化阶段,网络结构聚焦阶段,城市网络的空间、地位、经济等多元阶段变迁;②研究由城市网络链接结构、全球中心城市、城市网络节点地位及城市网络经济学四大主题构成;③以往研究缺乏对网络结构绩效的研究,对非世界城市的关注不够,城市地位与经济之间的关系仍处于描述阶段;④对世界城市网络结构的内涵、非世界城市研究、整体网络与个体网络关系、经济学方向进行展望,使世界城市网络的未来研究更加全面丰富。     

Lichenometric constraints on the age of the Huashan Grottoes, East China

Lichenometry is a method of dating that has been widely used in glaciated areas for determining the minimum age of exposure of a geomorphic landform during the late Holocene. This paper presents a regional calibration data set of lichen thallus sizes versus rock surface ages for the Huashan area, East China, based on measurements of yellow-green Rhizocarpon lichens on the known-age substrates at eight sites. An empirical relationship between thallus sizes and rock surface ages was established using both the traditional regression and the Bayesian approaches. Using the Bayesian calibration, the minimum age of the Huashan Grottoes was dated from 450 ± 60 to 330 ± 60 years ago, corresponding to the late Ming Dynasty (AD 1477–1632). These dates are generally consistent with those predicted from the regression-based linear growth curve. Our results suggest that applications of this technique can be safely extended to the non-glaciated areas.     

从最近的考古发现看北方粟作农业的起源问题

中国北方最早的粟作农业可以追溯到距今16000年的山西下川旧石器晚期文化,而距今13000年～9000年是中国北方粟作农业的大发展阶段,其中,北京东胡林人类文化遗址为这个发展过程提供了比较丰富的资料.可以证实华北是中国北方农业文明的重要发源地.
