从群体遗传的DNA线索看东乡族族源问题

DNA分析技术的发展为进行民族识别和分析民族起源、迁徙、流动、融合提供了新手段。本文在国内外首次应用D13S317基因座第 11号等位基因频率指标 ,计算了东乡族群体遗传动态数据。结果发现 ,东乡族和回族遗传距离很近 ,且东乡族中具有白种人血缘混杂。结合其他有关资料 ,我们认为东乡族的起源与元代蒙古军带来的中亚工匠、签军有关 ,亦与当地蒙古族、回族、藏族人群的融合有关。本文的研究结果可以为民族研究提供群体遗传方面的线索     

建立和完善工业反哺农业财政机制

当前,我国总体上已进入工业反哺农业阶段,财政机制在其中扮演着极其重要的角色。但就目前而言,工业反哺农业财政机制的建立与完善仍然受到经济发展水平与国民经济分配格局、现行财政体制、基层政府执政能力、宏观经济政策等条件的约束。对此,应以城乡协调发展、科学规范、事权与财权相统一、公开透明、循序渐进、市场调研与财税调控相结合等为原则,建立财政反哺农业增长的长效机制,调整财政支农结构,转换农村反哺供求连接机制,建立和完善财政农业资金绩效评估与监管机制,以及制定相关配套措施。

Outlier detection and robust variable selection via the penalized weighted LAD-LASSO method

This paper studies the outlier detection and robust variable selection problem in the linear regression model. The penalized weighted least absolute deviation (PWLAD) regression estimation method and the adaptive least absolute shrinkage and selection operator (LASSO) are combined to simultaneously achieve outlier detection, and robust variable selection. An iterative algorithm is proposed to solve the proposed optimization problem. Monte Carlo studies are evaluated the finite-sample performance of the proposed methods. The results indicate that the finite sample performance of the proposed methods performs better than that of the existing methods when there are leverage points or outliers in the response variable or explanatory variables. Finally, we apply the proposed methodology to analyze two real datasets.     

Stereotype and National Attachment in Hong Kong Chinese Context: A Moderated Mediation Model of Perceived Inter-group Relationship and Age

The present study investigated the relationship between Hong Kong people’s stereotype toward Mainland people and their own national attachment (i.e., national identity, constructive patriotism, and uncritical patriotism). The role of inter-group relationship as mediator and age as moderator of that relationship were also tested. A total of 1753 local Hong Kong people aged 17–80 (mean age = 20.35 years, SD = 5.02) completed anonymous questionnaires regarding their stereotypes toward Mainland people, inter-group relationship with Mainland people, and national attachment. As expected, stereotypes toward Mainland people, inter-group relationship and national attachment showed significant positive associations with each other. More interestingly, it was found that the inter-group relationship mediated the relationship between stereotypes toward Mainland people and three domains of national attachment, with this indirect link being weaker for younger Hong Kong adults than for older Hong Kong adults. Implications of the present findings for future research are discussed, as well as potential interventions for increasing subjective national attachment to China, especially in young Hong Kong people.
