A new dysagrionid damselfly (Odonata: Zygoptera: Palaeodysagrion) from mid-Cretaceous Burmese amber

AUTHOR, N. &; AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang &; Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion. It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.

释楚郾客铜量中的“故”字

本文通过将郾客铜量与楚简文字对比,认为郾客铜量中的"■"字当隶定为"■",读为"故",并将包山68号简释为"耆州"的"耆"字改释为"■",此字可能为楚文字中"故"的专字,进而对郾客铜量铭文中仍存在的问题加以探讨,以待考古学的进一步求证。

A new species of Aboilinae (Orthoptera: Prophalangopsidae), Aboilus perbellus, is described and illustrated based on three well-preserved forewings recovered from the Middle–Upper Jurassic Daohugou beds of Inner Mongolia, China. The new species differs from all congeneric forms in its special forewing coloration and features of its wing venation. To date, three types of forewing coloration have been found among different species of Aboilus at Daohugou, suggesting that these taxa inhabited different ecotopes.     

A new saucrosmylid lacewing (Insecta,Neuroptera) from the Middle Jurassic of Daohugou,Inner Mongolia,China

A new genus and new species of Saucrosmylidae (Insecta, Neuroptera) are described (Daohugosmylus castus) based on a well-preserved hindwing from the Middle Jurassic of Daohugou, Inner Mongolia, China. Daohugosmylus gen. nov. is distinguished by a large and nearly semi-circular hindwing, relatively wide R1 space possessing several rows of cells, anteriorly bent Rs, dense crossveins over the entire wing, and smooth outer margin.

Beam-Column Joint Model for Nonlinear Analysis of Non-Seismically Detailed Reinforced Concrete Frame

An efficient and simplified plane beam-column joint model that can describe the strength deterioration, stiffness degradation, and pinching effect was developed for the nonlinear analysis of non-seismically detailed reinforced concrete frames. The proposed beam-column joint model is a super-element consisting of eight spring components and one panel zone component, representing the bond-slip mechanism of the longitudinal reinforcement and the shear deformation mechanism of the joint concrete core region, respectively. In order to represent the dynamic response at the system level, the elastic constitutive law is applied to the eight connector springs, while the Bouc-Wen-Baber-Noori (BWBN) model is adopted to describe the hysteretic behavior of the panel zone component. For the implementation of the finite element analysis, the algorithmically consistent tangent of the BWBN model is derived as a uni-axial constitutive model, while the initial stiffness of the panel zone component is determined by the concrete compression strut assumption. The accuracy and efficiency of the proposed beam-column joint model were calibrated at both the component and structural levels by comparing the simulated results with the experimental data for non-seismically detailed joint sub-assemblages and a reinforced concrete plane frame.     

清代中外西藏阿里的自然地理知识初探

清代西藏阿里地区虽然与中原内地相距绝远,然而在清代前期中央国家的积极努力之下,中原内地对阿里的自然地理知识的获得取得了相当大的成就,尤其是对阿里地区的名山大川的分布及其详情在感性认识层面上达到了相当的高度,然而这种势态没能继续发展下去,从清代中后期开始,这一热情逐渐消退,相关的自然地理知识增长缓慢。另一方面,从清代中后期开始,西方殖民者和探险家进入西藏,对阿里地区进行了一系列的近代地理学的勘测和总结,世人所知的阿里自然地理知识有了迅速发展,形成了一系列丰富的内容。本文拟以清代中原地区的官私著作和西方探险家的考察报告、游记等材料,重现清代西藏阿里自然地理知识的累积过程和发展水平。

民俗学视野下历史民俗文献研究的意义

我国是一个拥有悠久民俗传统的国家,也是一个乐于并善于将民俗传统记录下来、将对民俗传统的理解表达出来因而拥有丰富历史民俗文献的国家。从学术分工上看,整理研究历史民俗文献更多是由从事历史民俗学研究的学者来担当,但对历史民俗文献进行整理和研究的意义却不局限于历史民俗学,而是惠及包括历史民俗学、记录民俗学和理论民俗学在内的整个民俗学学科。民俗学的历史民俗文献研究是为着民俗学的,也是属于民俗学的。民俗学对于历史民俗文献的界定本身是对文献的一种理解,其研究过程中对文本与生活关联取向的谋求也丰富着文献研究的径路。
