First fossil thaneroclerid beetle from mid-Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae)

Cai, C. & Huang, D., January 2018. First fossil thaneroclerid beetle in Upper Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae). Alcheringa 42, 115–119. ISSN 0311-5518.

Thanerocleridae is a small family of Cleroidea with no fossil representatives to date. Here we describe and figure the first fossil representative of Thanerocleridae, Cretozenodosus fossilis gen. et sp. nov., from the mid-Cretaceous amber of northern Myanmar. Cretozenodosus is referred to the extant subfamily Zenodosinae as evidenced by its open procoxal cavities and transverse procoxae. Cretozenodosus has close affinities with the North American Zenodosus Wolcott, suggesting that modern Zenodosinae is probably a relict group. Our discovery of a new thaneroclerid genus from Burmese amber suggests that Thanerocleridae originated no later than the mid-Cretaceous.

A new fossil sinoalid species from the Middle Jurassic Daohugou beds (Insecta: Hemiptera: Cercopoidea)

Fu, Y., Cai, C. & Huang, D., October 2017. A new fossil sinoalid species from the Middle Jurassic Daohugou beds (Insecta: Hemiptera: Cercopoidea). Alcheringa 42, 94–100. ISSN 0311-5518.

A new fossil species, Luanpingia daohugouensis sp. nov., belonging to the family Sinoalidae is described from the Middle to Upper Jurassic Daohugou beds of Inner Mongolia, China, on the basis of two well-preserved complete specimens. The described species of Sinoalidae are reviewed and Jiania gracila is considered a junior synonym of Jiania crebra. The new discovery increases the palaeodiversity of sinoalids from the Daohugou beds. It also indicates stratigraphic correlation between the Daohugou beds, the Haifanggou Formation at Haifeng, Beipiao City, West Liaoning Province, and the Jiulongshan Formation at Zhouyingzi, Luanping County, Hebei Province. All of these units host the ‘early assemblage’ of the Yanliao biota.

Modification of Ductility Reduction Factor for Strength Eccentric Structures Subjected to Pulse-Like Ground Motions

This article investigates the ductility reduction factors for RC eccentric frame structures subjected to pulse-like ground motions. The structural models are with the strength eccentricities which are much disadvantageous than the stiffness eccentricities during the inelastic response range. A method to determine the ductility reduction factors of the strength eccentric structures is suggested by modifying those of reference symmetric structures through an eccentricity modification factor. The four factors of strength eccentricity ratio, ductility ratio, story number and velocity pulse of ground motions, are investigated to gain insight into this modification factor. It shows that the ductility reduction factors of the eccentric structures are clearly smaller than those of the symmetric structures. The eccentricity modification factor is mainly affected by the strength eccentricity and the ductility ratio, decreasing with the increment of the eccentricity or the decrement of the ductility ratio in a medium eccentricity range. The earthquake pulse-like effect and the eccentricity have coupling influence on the modification factor, while the effect of story number is not apparent. Based on the results of a comprehensive statistical study a simplified expression is suggested, which can estimate the eccentricity modification factors for both pulse-like and nonpulse-like ground motion cases.     

Barton Hill Pottery and the post-medieval redware industry in Bristol

SUMMARY: Excavation in advance of a new housing development on the site of the Barton Hill Pottery, Bristol, uncovered the full footprint of a late 19th-century pottery, a large quantity of redware wasters, and a dump of whiteware wasters from another nearby factory, which include examples of Royal Navy mess ware.     

Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae)

Cai, C. & Huang, D., September 2016. Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Omma Newman is an extant ommatid genus currently endemic to Australia. A new Omma species, O. daxishanense sp. nov. is described and illustrated based on a compression fossil from the Upper Jurassic Tiaojishan Formation at Daxishan, a fossil locality well known for yielding mammals, feathered dinosaurs and diverse pterosaurs. Omma daxishanense is very similar morphologically to the extant O. sagitta, but differs from the latter by its broader body and prominent temples. The new discovery documents the first valid Omma species from the Mesozoic of China and highlights the antiquity and palaeodiversity of the extant Australian endemic genus.

论李维的历史方法

李维的历史方法是罗马传统历史方法的继承与发展。首先,他采用了逐年纪事的年代记的叙述方式。其次,他继承了罗马史学在其肇始就具有的爱国主义偏见和为罗马辩护的特点,特别是在对史料的处理方面,他按照爱国主义和道德教导的写作目的对史料进行删选,甚至伪造。最后,李维把文学技巧应用到历史写作之中。

Who Said, “Confucius Composed the Chunqiu”? ——The Genealogy of the “Chunqiu” Canon in the Pre-Han and Han Periods

It is often said that “Confucius composed the Chunqiu 春秋 (The Spring and Autumn Annals) to convey the way of the king.” Scholars have long noticed that before the founding of and during the Han Dynasty the phrase that served as the title of the allegedly Confucian work, “Chunqiu,” was also often used to designate history in general. In what intellectual and textual contexts did the term evolve from something general into a specific concept associated with Confucius? What works or ideas did pre-Han and Han scholars have in mind when discussing Confucius’s Chunqiu and the broader “Chunqiu” canon?1 Exploring these questions, the study that follows begins by systematically documenting the occurrences of this term in pre-Han and Han texts. It demonstrates that while Mencius was the first person to associate Confucius’s teachings with the Chunqiu, his statement was a solitary and surprising voice in the pre-Han era. Not until the Western Han Dynasty was Confucius widely heralded as the creator of the Chunqiu. But few scholars are aware that Western Han scholars never strictly distinguished the laconic Chunqiu from the detailed historical knowledge preserved in the Gongyang 公羊, Guliang 谷梁, and Zuo 左 commentaries. Furthermore, as the Chunqiu gained canonical status, the phrase still served as a generic term, referring to various historical narratives. Zhang Xuecheng 章学诚 is famous for claiming that “The Six Classics are all history,” and I shall show that in the minds of the people of the Han Dynasty, all historical works were classics.
