论江泽民的源头治腐思想

作为我党第三代领导集体的核心,江泽民同志非常重视深入开展党风廉政建设和反腐败斗争,从三个方面阐述了如何预防和治理腐败问题:从思想上筑牢反腐倡廉,拒腐防变的堤防;从体制上逐步铲除腐败现象产生的土壤和条件;从机制上遏制腐败现象的滋生和蔓延。     

云南跨境民族的分布、来源及其特点

就狭义跨境民族与广义跨境民族的区分原则提出了看法,考证并叙述这些跨境民族在云南境内外的分布及其来源。同时指出,国境两侧跨境民族的类别与人口较多,一些跨境民族虽有较大的聚居区,但各民族交错杂居与插花式分布的情形十分普遍,各跨境民族长期友好相处、相互关系较融洽,是云南境内外跨境民族在分布与来源方面的主要特点。

Emergence of life—how and where?—An update based on recent ideas

Panspermic origins notwithstanding, life, assuming that it started on Earth, may have taken root as soon as it became geologically permissible. There are multiple possibilities for early biogenesis from complex inorganic/organic geochemistry at diverse geological niches. Recent theoretical calculations have revived the possibility of Earth having a rather reduced early atmosphere, and had refueled arguments for a surface origin of life. Laboratory modeling of possible prebiotic RNA polymerization has seen interesting experimental advances, although a plausible replicator-like molecule has not yet been produced. The hydrothermal origin school of thought has also seen an interesting postulation for life’s early emergence and evolution—within contiguous, porous hydrothermal iron-sulfide (FeS) compartments, leading to a non-free living last universal common ancestor (LUCA). A confined LUCA evolving later into free-living archaebacteria and eubacteria could potentially reconcile some problems of molecular divergence between these two kingdoms. There are, however, many unresolved problems, and experimental evidence for such a scheme is lacking. Here, recent updates and refinements to the mainstay hypotheses for the emergence of life on Earth are reviewed and discussed.     

Mitochondrial DNA analysis of Bronze Age horses recovered from Chifeng region, Inner Mongolia, China

In this study, mitochondrial DNA (mtDNA) analysis was carried out on 9 Bronze Age horses recovered from Dashanqian and Jinggouzi archaeological sites in Chifeng region, Inner Mongolia. China to explore the origin of Chinese domestic horses. Both mtDNA 16S rRNA gene and control region (D-loop) fragments of ancient horses were amplified and sequenced. The analysis of the highly conservative 16S rRNA gene sequences indicated that the burial environment of Chifeng region is suitable for the preservation of ancient DNA (aDNA). Combing 465 mtDNA D-loop sequences representing different breeds from East Asia, Central Asia, Near East and Europe, we constructed a phylogenetic network to investigate the relationship between ancient and modern horses. The phylogenetic network showed that the 9 horses were distributed into different modern horse clusters which were closely related to them representing a certain geographical distribution. Our results showed that the maternal genetic line of the ancient horses in Chifeng region was highly diversified, which contributed to the gene pool of modern domestic horses and suggested a complex origin of domestic horses in China.     

Stable isotopic analysis on sus bones from the Wanfabozi site, Tonghua, Jilin

In order to study the sus diets and explore the possibility to distinguish domestic pig from wild boar through dietary analysis, stable carbon and nitrogen isotopes of 28 pig bones from archaeological site of Wanfabozi in Tonghua City, Jilin Province were analyzed. The δ^13C and δ^15N values of uncontaminated bones show that the overall pigs in the site were generally herbivores and ate mainly C3 plants. Significant difference of δ^15N values was observed between wild boar and domestic pigs, which may result from the higher consumption of animal protein in domestic pigs other than from that in wild boar, possibly from human leftover or waste,. The dietary difference between wild boar and domestic pigs has great potential to differentiate wild boar and domestic pigs in the early stage of pig domestication.     

农民工问题的由来实质与标本兼治

农民工是我国现代化进程中形成的特殊社会群体.农民工问题的实质就是如何对待现代化进程中的农民问题.农民工为社会主义现代化建设作出了诸多贡献,但在现实社会中,却面临着很多不公正的待遇.标本兼治是解决农民工问题的根本之策.农民工问题的最终解决只有随着现代化程度的不断提高,才能顺利完成.农民工最终必将转变为新时期的产业工人.     

黔西南地区高砷煤与金矿的成因研究

峨眉地幔热柱活动在早、晚二叠世之间喷发大规模峨眉山玄武岩浆，其间大量的As、Au及其它微量元素呈极分散均一状态进入黔西南兴义、安龙、兴仁、贞丰一带较为闭塞、台地相与台地边缘斜坡相过渡地带的龙潭组煤系地层中．在燕山期峨眉地幔热柱再次活动作用下，从峨眉山玄武岩、煤系地层中萃取大量As、Au等成矿物质形成的热液发生活化迁移，在通过煤层时几、Au在局部地段的黄铁矿中富集，形成高砷煤及金矿床．强烈的峨眉地幔热柱活动提供黔西南高砷煤、金矿形成的成矿物质来源及成矿动力来源．图3，表5，参11．
