Phylogenetic analysis of a new fossil Notonectidae (Heteroptera: Nepomorpha) from the Late Jurassic of China

Zhang W.T., Yao Y.Z. & Ren D., June 2012. Phylogenetic analysis of a new fossil Notonectidae (Heteroptera: Nepomorpha) from the Late Jurassic of China. Alcheringa, 239–250. ISSN 0311-5518.

A new fossil species Notonecta vetula sp. nov. is described and illustrated using nymph and adult fossil specimens collected from the Upper Jurassic Chijinqiao Formation, Yumen City, Gansu Province, China. A phylogenetic analysis, based on a combination of fossil and extant backswimmers, was conducted to confirm the position of the new fossil within the Notonectidae.

敦煌写本张仲景《五脏论》考辨

目前发现的敦煌写本《五脏论》有四个卷号,诸家对此进行了录校和注释,但是千虑一失之处还是存在的。本文以最完整的P.2115V0为底本,比对另外三种卷子和诸家校注,从语言文字的角度,校释数处有争议的地方。     

新时期农村合作医疗改革述论

新时期农村合作医疗经历了曲折的发展历程。随着家庭承包经营的推行,农村合作医疗迅速瓦解,覆盖率由20世纪70年代末的90%下降到1985年的5%。90年代初开始,党和政府努力恢复合作医疗,但重建工作一再受挫。农民自费医疗的境况带来了严重的社会问题。2003年初,新型农村合作医疗制度出台,这是又一项富有中国特色的社会主义制度创新。几年来的试点和推广实践证明,新型农村合作医疗制度符合我国的实际,对保障农民身体健康、维护社会和谐和促进经济发展具有重要意义。同时,建立完善的农村医疗保障制度需要各方力量的整合,任重而道远。     

越国乐器研究

春秋末年,地处中国东南一隅的越国,西灭强吴,争霸中原,一跃成为当时的强国之一。“允常之时。拓土始大。称王”,绍兴印山越王允常陵的发现,已使人对越文化刮目相看;而无锡鸿山越国贵族墓的发现,更使人领略到越文化的风采与辉煌。     

The Shuidonggou site complex: new excavations and implications for the earliest Late Paleolithic in North China

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.     

《奉贤县续志》序

以前志主编的身份,在离开家乡近20年之后能为家乡续志写序,我感到无上荣光。我想,这是相当特殊的个例,就是在全国方志界也许不会很多吧。     

一度梅花一度春

好一个新世纪的金秋,好一个新面貌的首都,好一个新的起点。十七大所作出的每一项一项决策、提出的每一条方针、表达的每一个思想、设置的每一个目标,都富有历史性意义。百岁老人帅孟奇曾诗云:"一度梅花一度春,傲霜战雪岁迎新。漫山争艳向阳发,粗枝老梅绿叶生。"艺术性地表达了这种政治性的意蕴。

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.
