曾公■钟铭初读

新近公布的曾公■钟铭是一篇曾国宗庙祭祀文书,由三部分构成:一是赞颂高祖伯括的生前事功及福赐子孙;二是颂扬皇祖南公受昭王命"建于南土",以至受赐铜钺,"用政南方"。曾之"皇祖"在周昭王时期的二次受命,过去未见记载;三是器主程式化的自述和祈福。结合曾侯与钟、加嬭编钟铭文,可证伯括因勤劳文武,故在周成王时受封立国。曾公■钟铭受昭王诰命的"皇祖",疑即随州叶家山M111墓主曾侯犺。曾国二次受命以后,被周王朝授予主政南土的职责,由此奠定了日后"汉东之国随(曾)为大"的基础。     

美国学界关于中国共产党城市接管史研究述评

新中国城市接管是城市管理与城市建设的一个特殊阶段,其时间虽然较短,但影响深远。中国共产党对新解放城市的接管是中华人民共和国大厦的奠基石,也是中国共产党建政成功与否的关键。因此,研究中共城市接管是洞察中国共产党政权建构与施政理念的重要切入点。美国学界持续关注中共城市接管史,研究内容涉及城市接管的过程、接管干部(含南下干部)以及城市接管之后的社会改造和城市变迁等。随着研究视角的转换,美国学界的关注点亦有所不同。近些年来美国学界相关的研究议题越来越细化,关注点从宏大的政治叙事转向社会结构和城市生活变迁,而研究方法也呈现多样化的趋势。     

IBEM for Impedance Functions of an Embedded Strip Foundation in a Multi-Layered Transversely Isotropic Half-Space

An indirect boundary element method (IBEM) is developed to study the dynamic impedance functions (stiffness coefficients) of a rigid strip foundation embedded in a multi-layered viscoelastic transversely isotropic (TI) half-space. The proposed IBEM using half-space Green’s functions of distributed loads as fundamental solutions have the merits of fictitious loads being directly applied on the real boundaries without the problem of singularity and of the discretization effort restricted to local boundaries. In addition, the accuracy of the proposed method is not affected by the thickness of the discrete TI layers, as the exact dynamic stiffness matrix is employed. The presented algorithm is verified via comparisons with published results for the isotropic medium. By taking a rigid strip foundation embedded in a homogeneous half-space, a single-layered half-space, and a multi-layered half-space as examples, the effects of material anisotropy, frequency of excitation, and soil layer on the impedance functions are studied in detail. Numerical results show that impedance functions for the TI medium can be significantly different from those of the isotropic case. The variation of TI parameters alters the dynamic characteristics of the TI layered site, which in turn alters the dynamic interaction between the soil and foundation. In addition, the soil sedimentary sequence also has a remarkable influence on the impedance functions.     

Cultivation of Naked Barley by Early Iron Age Agro-pastoralists in Xinjiang,China

ABSTRACT

We report an archaeobotanical analysis of flotation samples taken from Shirenzigou, an Early Iron Age agro-pastoralist site dated between the fourth and first century BC, located on the northern slope of the Tianshan Mountains in Xinjiang, China. The charred macro-botanical assemblage is dominated by naked barley grains with a few broomcorn and foxtail millet grains. In the context of Trans-Eurasian exchange of cereal crops, southwest Asian crops (wheat and barley) and two Asian millets (broomcorn and foxtail) were introduced to Xinjiang a few centuries to a millennium before Shirenzigou was occupied. The choice of barley cultivation in preference to wheat and millet may have been possibly driven by the relatively extreme local environment and the scheduling requirements of mobile pastoralism. Barley is well suited to this environment, and the choice of naked barley in preference to hulled barley may have been driven by the whole grain tradition prevailing in East Asia.     

New Jurassic predatory cockroaches (Blattaria: Raphidiomimidae) from Daohugou,China and Karatau,Kazakhstan

Liang, J., Shih, C. &; Ren, D., October 2017. New Jurassic predatory cockroaches (Blattaria: Raphidiomimidae) from Daohugou, China and Karatau, Kazakhstan. Alcheringa 42, 101–109. ISSN 0311-5518.

Two new species and a new combination in a new genus of predatory cockroaches, Falcatusiblatta gracilis and F. qiandaohua from the Middle Jurassic Jiulongshan Formation of Daohugou, China and F. karatavica (Vishniakova) comb. nov. from the Upper Jurassic Karabastau Formation of Karatau, Kazakhstan are described within Raphidiomimidae. The new taxa are distinguished by the presence of a very long ovipositor (plesiomorphy) and elongate cerci with heteronomous articles and forewing markings with irregular patch-like shapes of light and dark patterns (autapomorphies).

Electrical Resistivity Tomography with Angular Separation for Characterization of Burial Mounds in Southern China

The study aims at providing the spatial distribution and potential structure of the burial mounds at the Sifangling site, Hepu Han Tombs, in southern China. We implemented an electrical resistivity tomography (ERT) technique to obtain high‐resolution imaging of archaeological targets, considering the challenging environment and the depth of the burials. Three ERT profiles were tested above a small ancient mound previously detected by exhaustive archaeological drillings, following which 18 ERT profiles with angular separation were performed on the largest mound at the test site, without any a priori archaeological evidence below the surface. Then, a series of two‐dimensional (2D) profiles were combined as a ‘pseudo‐3D’ volume, which allowed a detailed characterization of the burial mound, and iso‐resistivity surfaces were also calculated to emphasize the location and spatial extent of the target. The results gave an effective identification of the funeral chamber and its structural details, and allowed detailed pre‐excavation planning.     

Latinos and Environmental Justice: Examining the Link between Degenerative Policy,Political Representation,and Environmental Policy Implementation

The theory of social construction and policy design is insightful for exploring the circumstances in which the allocation of policy benefits and burdens is attributed to the feed‐forward effect of degenerative policy that institutionalizes bias and reinforces the prevailing categorization and embedded social meaning regarding target populations. However, this theoretical framework has not been broadly adopted to analyze the environment‐related phenomena. With a nationwide, block‐group‐level sample, this study examines the extent to which degenerative policies pertaining to immigrants influence state agencies' environmental regulatory outputs for predominantly Latino communities. Results show that in the states with moderately to most restrictive immigrant policy and high levels of Latino representation in legislatures, the rigorousness of government agencies' compliance monitoring activities decreases for Latino neighborhoods of environmental justice concern, as states' policy stance toward immigrants becomes more unfavorable. More Latino elected officials do not bolster policy implementation efforts for the vulnerable communities or offset the backlash effect of immigrant policy.
