论中国古代乡村治理之得失

在中国古代的乡村治理诸问题中,王朝政权始终是主角。无论是乡里体系还是户籍管理,无论是教化、信仰还是宗族政策,都处于王朝政权的直接主导之下。这是由中国古代农耕文明发展道路与大一统政治体制所决定的,与欧洲中世纪乡村社会治理的... 详细信息

在中国古代的乡村治理诸问题中,王朝政权始终是主角。无论是乡里体系还是户籍管理,无论是教化、信仰还是宗族政策,都处于王朝政权的直接主导之下。这是由中国古代农耕文明发展道路与大一统政治体制所决定的,与欧洲中世纪乡村社会治理的路径存在明显不同。欧洲中世纪乡村社会治理的多元与复合源于整个社会结构的多元化构造,有其自身鲜明特色;中国古代乡村社会治理的政府性与统一性既来自整个社会构造的一体与统一,又为大一统中央集权国家的形成与发展奠定了基础,是中国古代农耕文明的产物,具有特定历史价值与现实镜鉴意义。

作者：马新山东大学历史学院

汉代村落空间构造在继承原始聚落与早期村落传统的同时,补充与强化了各种要素组成,使村内居住区与村外祖茔区所构建的二元格局不断完善,村落空间布局、层次结构以及要素配置适应了战国以来农耕文明的发展变化,奠定了中国古代村落空间构... 详细信息

汉代村落空间构造在继承原始聚落与早期村落传统的同时,补充与强化了各种要素组成,使村内居住区与村外祖茔区所构建的二元格局不断完善,村落空间布局、层次结构以及要素配置适应了战国以来农耕文明的发展变化,奠定了中国古代村落空间构造的基础。汉代村落空间构造所具有的特性,造就了中国古代村落的独有功能与价值。无论是王朝更迭,还是社会动荡,村落都是最为稳定的存在。正因为此,村落也就成为中国古代农耕文明基因递延与发展的基本载体,是中华文明连绵不绝的基础所在。

Nest predation is the leading cause of reproductive failure in birds and a major driving force in the evolution of anti-predation strategies. Current studies on the anti-predation strategies of birds driven by predation pressure have mainly focused on adults. However, the detection and behavioral responses of nestlings toward predation risk require further investigation. In this study, we examined nestling responses to predator sounds. Two species of nestlings, the Reed Parrotbill(Paradoxornis heudei) and Vinous-throated Parrotbill(Sinosuthora webbiana),were exposed to the Sparrowhawk(Accipiter nisus, less common) and Oriental magpie(Pica serica, more common), which are predator species, the Oriental Turtle Dove(Streptopelia orientalis), which is a commonly found harmless species, and background noise. Our findings revealed that compared to pre-playback of natural begging and playback of background noise and Oriental Turtle Dove sounds, playback of the two predator types decreased the total begging time and total number of calls of the two nestlings species, with the calls of the Sparrowhawk leading to greater suppression of nestling begging behavior than those of the Oriental ***, our results indicated that these nestlings were able to distinguish predators from harmless species based on auditory cues.

Soybean seed isoflavones are a type of secondary metabolites that can provide health and nutrition benefits for humans. In our previous study, a stable quantitative trait locus(QTL) qIF05-1 controlling the seed isoflavone content in soybean was detected on chromosome(Chr.) 05 in a recombinant inbred line(RIL) population from a cross of Huachun 2×Wayao. In this study, the parental lines were re-sequenced using the Illumina Solexa System with deep coverage. A total of 63,099 polymorphic long insertions and deletions(InDels)(≥15 bp)were identified between the parents Huachun 2 and Wayao. The InDels were unevenly distributed on 20chromosomes of soybean, varying from 1,826 in Chr. 12 to 4,544 in Chr. 18. A total of 10,002 long InDels(15.85% of total) were located in genic regions, including 1,139 large-effect long InDels which resulted in truncated or elongated protein sequences. In the qIF05-1 region, 68 long InDels were detected between the two parents. Using a progeny recombination experiment and genotype analysis, the qIF05-1 locus was mapped into a 102.2 kb genomic region, and this region contained 12 genes. By RNA-seq data analysis, genome sequence comparison and functional validation through ectopic expression in Arabidopsis thaliana, Glyma.05G208300(described as GmEGL3), which is a basic helix-loop-helix(bHLH) transcription factor in plants, emerged as the most likely confirmed gene in qIF05-1. These long InDels can be used as a type of complementary genetic method for QTL fine mapping, and they can facilitate genetic studies and molecular-assisted selection breeding in soybean.

The unavoidable dendrite growth and shuttle effect have long been stranglehold challenges limiting the safety and practicality of lithium-sulfur ***,we propose a dual-action strategy to address the lithium dendrite issue in stages by constructing a multifunctional surface-negatively-charged nanodiamond layer with high ductility and robust puncture resistance on polypropylene (PP) *** uniformly loaded compact negative layer can not only significantly enhance electron transmission efficiency and promote uniform lithium deposition,but also reduce the formation of dendrite during early deposition *** importantly,under the strong puncture stress encountered during the deterioration of lithium dendrite growth under limiting current,the high ductility and robust puncture resistance(145.88 MPa) of as-obtained nanodiamond layer can effectively prevent short circuits caused by unavoidable lithium *** Li||Li symmetrical cells assembled with nanodiamond layer modified PP demonstrated a stable cycle of over 1000 h at 2 ma cm^(-2)with a polarization voltage of only 29.3 ***,the negative charged layer serves as a physical barrier blocking lithium polysulfide ions,effectively mitigating capacity *** improved cells achieved a capacity decay of only 0.042%per cycle after 700 cycles at 3 C,demonstrating effective suppression of dendrite growth and capacity attenuation,showing promising prospect.
