美丽乡村建设是乡村振兴的核心内容之一,需要村委会、村民等相关主体的共同参与.在乡村振兴的背景下,基于价值共创理论,构建村委会和村民乡村美丽价值共创行为的演化博弈模型,并通过Matlab软件进行仿真.研究发现,双方价值共创行为的演化结果主要受到投入成本、能力水平、声誉损失、参与效益及价值共创额外总收益的影响.研究对双方选择参与的初始比例、额外总收益、经济性激励以及能力水平对演化结果影响进行了讨论.结果发现,当初始概率大、获得收益高、能力水平强时,系统收敛于双方都选择参与策略的概率增大.据此提出降低投入成本、发挥舆论导向作用、增加双方价值共创收益、建立合适的奖励机制、提升参与的初始比例的对策建议.

With comparative genomics approaches, we evaluated the evolutionary characteristics of conservation of exons which are expressed abundantly, moderately or lowly in mammals. Using non-coding regions and pseudogenes as controls, sequence identity, phastCons and Ka/Ks analyses were carried out and our results showed that as the exons of high abundance are highly conserved, the minor and low exons also showed conservative characteristics in evolution. Our findings suggested that the exons with less abundance which constitute a large proportion of distinct species in transcriptome of organisms are under functional constraint and might play certain roles in enriching biological complexity in the evolution of organisms.

To evaluate the gene admixture on the current genetic landscape in Gansu Corridor (GC) in China, the upper part of the ancient Silk Road which connects the Eastern and Central Asia, we examined mitochondrial DNA (mtDNA) polymorphisms of five ethnic populations in this study. Using PCR-RFLP and sequencing, we analyzed mtDNA haplotypes in 242 unrelated samples in three ethnic populations from the GC region and two ethnic populations from the adjacent Xinjiang Uygur Autonomous Region of China. We analyzed the data in comparison with the previously reported data from Eastern, Central and Western Asia and Europe. We found that both European-specific haplogroups and Eastern Asian-specific haplogroups exist in the Gansu Corridor populations, while a modest matrilineal gene flow from Europeans to this region was revealed. The Gansu Corridor populations are genetically located between Eastern Asians and Central Asians, both of who contributed significantly to the maternal lineages of the GC populations. This study made the landscape of the gene flow and admixture along the Silk Road from Europe, through Central Asia, to the upper part of the Silk Road more complete.

Journal of Genetics and Genomics 2010年第6期37卷 371-379页

作者： Yanrui Wu Yina Cun Jing Dong Jingru Shao Shengjun Luo Shengjie Nie haijing yu Bingrong Zheng Qi Wang Chunjie Xiao Human Genetics Center of yunnan University Kunming 650091 China The General Hospital of the Air Force Beijing 100036 China Center for Studies in Constitution Research of Traditional Chinese Medicine Beijing University of Chinese Medicine Beijing 100029 China

Based on the theory of constitution of Traditional Chinese Medicine （TCM）, the human population is divided into nine constitutions including one balanced constitution （Normality） and eight unbalanced constitutions （Yang-deficiency, Yin-deficiency, Phlegm-wetness, Qi-deficiency, Wetness-heat, Blood stasis, Depressed constitution, and Inherited special constitution）. Different constitutions have specific metabolic features and different susceptibility to certain diseases. However, whether a genetic basis accounts for such constitution classification is yet to be determined. Here we performed a genetic study to assess the association between genetic variations of metabolic genes including PPARD, PPARG and APM1 and the constitutions. A total of 233 individuals of the Han population in China were classified into four groups, Normality, Yang-deficiency, Yin-deficiency and Phlegm-wetness with whom 23 single nucleotide polymorphisms （SNPs） in the three genes were genotyped using polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP） method. Biased distribution of PPARD rs2267669 and rs2076167, APM1 rs7627128 and rs1063539 in Yang-deficiency, PPARG Prol2Ala in Yin-deficiency and PPARD rs2076167, APMI rs266729 and rs7627128 in Phlegm-wetness were observed. The frequencies of Haplotypel3 （Hapl3） of PPARG in Yin-deficiency, Hap25 of APM1 in Yang-deficiency and Hap2 of PPARD and Hapl4 of PPARG in Phlegm-wetness, were significantly different from those in Normality, suggesting those might be group-associated haplotypes. These results suggested that single SNP and haplotypes ofPPARD, PPARG and APM1 may underlie the genetic basis of the constitutions classified in TCM.

作为重要的情感特征,创业激情在新企业创建过程中发挥重要作用,是众多成功创业者所具有的共性特征,已成为创业领域的前沿问题,并吸引越来越多研究者加以探索。目前创业激情的研究多集中于探讨概念体系及创业者具有的激情如何影响创业成功,鲜有研究探究创业者具有这一情感因素对新企业内部员工层面因素的影响,特别是缺乏关于不同类型创业激情对员工创新行为的影响的研究。借助情感传染理论和领导-成员交换理论,构建感知的创业激情对员工创新行为的影响机理模型,将创业激情划分为探索激情、创建新企业激情、发展新企业激情3类,探讨员工感知的不同类型创业激情对感知信任和员工创新行为的差异化影响以及员工感知信任与其创新行为的内在关系,并在此基础上分析感知信任在不同类型创业激情对员工创新行为影响过程中的间接作用。以长春和郑州的122家新企业为样本,采用回归分析对相应假设进行实证检验。研究结果表明,员工感知的探索激情和发展新企业激情正向影响其感知创业者的信任,感知创业者的信任正向影响员工创新行为。同时,员工感知的探索激情和发展新企业激情均通过感知信任正向影响员工创新行为。然而,感知创建新企业激情消极影响感知创业者的信任并通过感知信任消极影响员工创新行为的两个假设并未得到数据支持。研究结论进一步揭示了情感的传递效应,较好地弥补了创业激情对员工层面创新行为的影响研究不足,丰富了创业领域非理性情感因素研究。指导新企业创业者在创建和发展企业的过程中,应当适时通过工作互动和非正式交流等形式向员工表达创业激情,并让其充分感知到被信任,从而更好地开展创新行为。
