Understanding human influence on climate change in China

China''s climate has been warming since the 1950s, with surface air temperature increasing at a rate higher than the global average. Changes in climate have exerted substantial impacts on water resources, agriculture, ecosystems and human health. Attributing past changes to causes provides a scientific foundation for national and international climate policies. Here, we review recent progress in attributing the observed climate changes over past decades in China. Anthropogenic forcings, dominated by greenhouse gas emissions, are the main drivers for observed increases in mean and extreme temperatures. Evidence of the effect of anthropogenic forcings on precipitation is emerging. Human influence has increased the probability of extreme heat events, and has likely changed the occurrence probabilities for some heavy precipitation events. The way a specific attribution question is posed and the conditions under which the question is addressed present persistent challenges for appropriately communicating attribution results to non-specialists.     

基于TCP下多线程WINSOCK编程

本文首先分析了在WINSOCK下具体网络编程过程中的实际需求,利用线程创建函数编写了服务器对多个客户同时响应的例子,即在每一个客户提出请求后,主程序调用CreateThread子函数创建一个线程去服务客户,而主程序返回去等待下一个客户请求,从而实现多个客户与服务器间的通信。     

加强高校班级管理,提高高校班级有效性

班级作为高校的“细胞”,班级有效性的高低,直接决定高校有效性的高低,加强高校班级管理是提高班级有效性的一个重要保证,本文分析了高校班级管理的特点,并针对高校班级管理的特点,提出了加强班级管理,提高高校班级有效性的几项措施。     

企业技术联盟绩效评价体系的比较和发展趋势分析

对于企业技术联盟而言,其绩效的测度一直引起人们的关注,但是不论是在理论上还是实践中都存在着诸多的分歧和争论。大量研究活动表明,企业技术联盟的绩效评价存在一定的复杂性。本文比较和评述了现有的企业技术联盟绩效评价体系,指出了其存在的局限性;并阐述了其发展趋势,包括:投入和产出的无形化;评价指标的非财务化;评价过程的动态化;评价标准的多样化;定量与定性相结合。

Genomic diversity and post-admixture adaptation in the Uyghurs

Population admixture results in genome-wide combinations of genetic variants derived from different ancestral populations of distinct ancestry, thus providing a unique opportunity for understanding the genetic determinants of phenotypic variation in humans. Here, we used whole-genome sequencing of 92 individuals with high coverage (30–60×) to systematically investigate genomic diversity in the Uyghurs living in Xinjiang, China (XJU), an admixed population of both European-like and East-Asian-like ancestry. The XJU population shows greater genetic diversity, especially a higher proportion of rare variants, compared with their ancestral source populations, corresponding to greater phenotypic diversity of XJU. Admixture-induced functional variants in EDAR were associated with the diversity of facial morphology in XJU. Interestingly, the interaction of functional variants between SLC24A5 and OCA2 likely influences the diversity of skin pigmentation. Notably, selection has seemingly been relaxed or canceled in several genes with significantly biased ancestry, such as HERC2–OCA2. Moreover, signatures of post-admixture adaptation in XJU were identified, including genes related to metabolism (e.g. CYP2D6), digestion (e.g. COL11A1), olfactory perception (e.g. ANO2) and immunity (e.g. HLA). Our results demonstrated population admixture as a driving force, locally or globally, in shaping human genetic and phenotypic diversity as well as in adaptive evolution.     

“共识”与“共识的程度”:国家形象认知的别种维度

论文循着国际合法性与国家形象之间的内在关联,尝试从国际合法性视角出发来建构国家形象认知。国家形象是一种主观见之于客观的活动,它直观地体现着一国的主流民众对他国的融汇情感在内的整体性知觉和评价,在此种意义上国家形象可以理解为共识;同时,国家形象并非静态的主客体关系的结果和单纯对现实的复制式描述,而是主体间进而是形象间交往互动的产物,其中不可避免地裹挟着国家间多重力量的博弈,在这种意义上国家形象可以表示为共识的程度。
