提高人口统计数据质量的对策研究——以人口迁移统计为例

我国人口统计数据主要来源于日常统计工作报表、统计抽样调查与普查,而关于人口迁移统计数据的采集主要集中于统计部门、公安部门和计生部门。本文通过这三大部门涉及人口迁移统计项目与内容的系统梳理,探析影响我国人口迁移统计数据质量的原因,据此提出提高人口迁移统计数据质量的对策建议。     

明末清初的平和窑青花瓷绘艺术初探

明末清初的平和窑青花瓷绘艺术，是当时那个历史时期所产生的艺术现象，它们的出现主宰着当时陶瓷装饰的流行走向，在装饰风格上存在着重所描绘物象的精神实质，重作者主观感兴的抒发，重意念的表现，因而较多地采用减笔画法。对于这种减笔画法，我们不能简单地把它理解为单纯的“形式”问题。当我们谈及明末清初的平和窑青花瓷绘艺术的时候，应该把它们看作是那个历史时期多种因素制约下的精神物化现象，并从中探究其风格的本质意义。     

Palate Shape and Depth: A Shape‐Matching and Machine Learning Method for Estimating Ancestry from Human Skeletal Remains

In the past, assessing ancestry relied on the naked eye and observer experience; however, replicability has become an important aspect of such analysis through the application of metric techniques. This study examines palate shape and assesses ancestry quantitatively using a 3D digitizer and shape‐matching and machine learning methods. Palate curves and depths were recorded, processed, and tested for 376 individuals. Palate shape was an accurate indicator of ancestry in 58% of cases. Cluster analysis revealed that the parabolic, hyperbolic, and elliptical shapes are discrete from one another. Preliminary results indicate that palate depth in Hispanic individuals is greatest. Palate shape appears to be a useful indicator of ancestry, particularly when assessed by a computer. However, these data suggest that palate shape is not useful for assessing ancestry in Hispanic individuals. Although ancestry may be determined from palate shape, the use of multiple features is recommended and more reliable.     

How East Asians View the Rise of China

Its newly acquired status as the world's second largest economy has entitled China to a more prominent role in global affairs, and increasingly, its behavior has drawn scrutiny from the world in ways that the country is ill-prepared for. The attention to China's rise, however, focuses not only on its economy but also on other aspects, including its military, diplomatic moves, domestic politics and its ‘soft power’, namely, its own image or self-projection and the world's perception or attitudes toward China. And yet, there has been no systematic investigation to evaluate how the world views a rising China. In this article, the authors applied the latest dataset from the Asian Barometer Survey to investigate whether East Asians recognize and welcome the rise of China. The findings suggest that geographical and cultural proximity have a great impact on people's perception of China. Countries which are territorially adjacent or culturally close to China tend to regard China as the most influential country in Asia. With the exception of Japan and Mongolia, most Asian countries hold positive views about the impact of China on the region. However, such benign evaluations are weaker in countries which have potential security conflicts with China, such as Taiwan and South Korea, when only the bilateral impact is considered. The overall picture shows that the rise of China has been largely recognized and welcomed by East Asians, despite some apprehension about China's strategic intentions to its neighboring countries.     

走出执法转型期困境的若干理论思考

为实现执法观念与执法方式由传统向现代转型,从第一线执法现状出发,应解决在经济发展与社会稳定、公正正义与公平正义、公正执法与效率保障、职能独立与警务泛化、行为危害性与人身危险性等方面存在的认识误区和矛盾阻力。     

DNA芯片技术检测HLA-DRB1和ABO基因型

用DNA芯片技术检测HLA-DRB1-ABO基因型。根据HLA和ABO不同基因亚型的独特序列设计探针,制成分型芯片;待检测样品经PCR反应标记上荧光之后,与探针在芯片上进行杂交,通过对杂交产生的荧光信号值进行分析,确定样品DRB1位点和ABO位点的基因亚型。将这一方法应用于111份样本的HLA-DRB1-ABO基因分型并将部分样品进行基因测序。检测结果证明本实验研制的HLA-DR-ABO基因分型芯片可准确分辨出DRB1位点30个等位基因、ABO位点6种基因型。该方法分辨率高、特异性强、重复性好、操作简便,对比常规的PCR-SSP方法,HLA-DR-ABO基因芯片方法更为直观,并具有集成化优势,可以在一张芯片上同时检测HLA和ABO位点,并实现一张芯片多人份,不仅适用于法医学亲子鉴定和个体识别,亦可应用于移植配型、HLA相关疾病及人类遗传学研究。     

全案例化：军校任职教育教学模式创新的重要选择

针对当前部队院校任职教育教学方法的落后状况,借鉴运用“M BA案例教学法”加以改进很有必要性。院校任职教育改革的关键,在构建以“提高分析和解决实际问题能力”为中心的新型案例教学模式,并力争把院校任职教育办成我军内部的“M BA”。
