网络意识形态是现实意识形态的非线性镜像。语言应激是当事人通过认知、评价而觉察到特定言语的威胁或者挑战而引起应对性的心理、生理反应。认知、情绪或者行为反应合理性程度明显弱化是语言应激障碍的具体表现。网络意识形态的语言应激障碍从现象看是语言表达冲突,事实上是语言意义冲突,本质上在于价值观冲突。

随着我国进入快速城市化阶段,大量新移民正成为城市常住居民的重要组成部分,该群体的社会融合与地方认同问题备受关注。依据塞缪尔·亨廷顿对地方认同的界定,构建结构方程模型,以广州、杭州、成都、沈阳、东莞、郑州6市的3164份调查问卷为基础,对中国大城市新移民的地方认同进行研究。研究发现,城市新移民正日益分化为劳力型、智力型和投资型移民3类,三大群体的地方认同存在较大差异。就认同机制而言,在个人特征、社会经济属性、制度、住房状况4个测量模型中,年龄、家庭生命周期、移民类型、月收入、户籍、社保状况、住房设施、住房类型等因素对地方认同的影响明显。结构模型分析表明,制度因素、住房因素、社会经济因素对新移民地方认同的直接效应依次递减,而个人特征通过社会经济因素对地方认同产生间接效应。总体而言,虽经多年市场化改革,制度因素仍是影响新移民地方认同乃至城市融入的最重要因素;住房状况对其地方认同的影响也在逐步增强。

A genome-wide association study(GWAS)identifies trait-associated loci,but identifying the causal genes can be a bottleneck,due in part to slow decay of linkage disequilibrium(LD).A transcriptome-wide association study(TWAS)addresses this issue by identifying gene expression-phenotype associations or integrating gene expression quantitative trait loci with GWAS ***,we used self-pollinated soybean(Glycine max[L.]Merr.)as a model to evaluate the application of TWAS to the genetic dissection of traits in plant species with slow LD *** generated RNA sequencing data for a soybean diversity panel and identified the genetic expression regulation of 29286 soybean *** TWAS solutions were less affected by LD and were robust to the source of expression,identifing known genes related to traits from different tissues and developmental *** novel pod-color gene L2 was identified via TWAS and functionally validated by genome *** introducing a new exon proportion feature,we significantly improved the detection of expression variations that resulted from structural variations and alternative *** a result,the genes identified through our TWAS approach exhibited a diverse range of causal variations,including SNPs,insertions or deletions,gene fusion,copy number variations,and alternative *** this approach,we identified genes associated with flowering time,including both previously known genes and novel genes that had not previously been linked to this trait,providing insights complementary to those from *** summary,this study supports the application of TWAS for candidate gene identification in species with low rates of LD decay.

外出农民返乡创业是缓解农村就业压力、提高农民收入和推动“打工经济”向“创业经济”转型的重要途径。本文使用双重差分法和全国县域面板数据,考察了返乡创业试点政策对农村居民收入的影响与机理。研究发现,该政策通过促进创业、推动第二、三产业发展以及吸引要素流入等途径,显著提高了试点地区的农村居民收入,且这种政策效应具有较好的包容性和农村偏向性。各地区的消费市场规模、金融效率、产业集聚程度和创业环境的发展差异,都会对返乡创业试点政策的农民增收效果产生门槛效应。各地区应不断加强对返乡农民的创业支持和政策引导,持续优化创业环境、加快非农产业发展、提高地区的要素吸引力并创造更多的创业就业机会,以提高农村居民收入和推动城乡均衡发展。
