In 2016, there were 17.8 million (15.4-20.3 million) women living with HIV/aiDS across the world and the prevalence of reproductive desire among this group was 26%-49%[1]. If pregnant women living with HIV/aiDS are left untreated, the rates of HIV transmission from mother-to-child would range from 14% to 48%, depending on the presence and duration of breastfeeding[2].

A fundamental tenet in theoretical ecology is the competitive exclusion principle. Two competitive species for a limited resource cannot coexist and thus one of the species will be driven to extinction. However, we show that noise can revise this principle in a resonance-like manner, which makes coherence resonance in the system. Our obtained results well enrich the findings in the interaction of populations in ecosystems, which may explain some filed observations in the real world.

Background C-reactive protein （CRP） gene ＋1059 G/C polymorphism has been reported to be associated with coronary heart disease （CHD） risk, but the results remain inconclusive. This meta-analysis was therefore conducted to clarify these controversies. Methods A comprehensive search was conducted to identify all case control studies on the association between CRP gene ＋1059 G/C polymorphism and CHD risk. All the related studies were further strictly selected according to the inclusion criteria. Meta-analysis was performed with STATA 10.1 （StataCorp, USA）. The association was assessed by odds ratio （OR） and 95% confidence interval （C/）; both Begg＇s funnel plot and Egger＇s regression test were used to assess the publication bias. Results This meta-analysis on a total of 13 studies comprising 6316 CHD cases and 4467 controls showed no significant association between CRP gene ＋1059 G/C polymorphism and CHD risk in the overall study （for C/C＋C/G vs. G/G： OR=1.01, 95% C/=0.81-1.25, P=0.96; for C/C vs. C/G＋G/G： OR=1.17, 95% C/=0.77-1.77, P=0.47; for C/C vs. G/G： 0R=1.17, 95% C/=0.77-1.77, P=0.47; for C allele vs. G allele： 0R=1.01, 95% C/=0.81-1.24, P=-0.96）. However, in the subgroup analysis by ethnicity, the results showed significant association between CRP gene ＋1059 G/C polymorphism and CHD risk among Caucasians （for C/C vs. G/G： OR=2.54, 95% C1=1.13-5.72, P=0.02; C/C vs. C/G＋G/G： OR=2.45, 95% C1=1.09-5.51, P=-0.03）, but not among Asians and Africans （P 〉0.05）. Conclusion CRP gene ＋1059 G/C polymorphism may be associated with increased CHD risk among Caucasians and more evidences need to validate the conclusion.

探究"公民"的时代性意蕴是认清公民教育真容的前提。公民教育是一种共同体教育、资格教育与使命教育,借助妥当的教育形态来推进这三重教育重任是当代学校教育的使命与职能。学校公民教育的内涵是"造就公民的教育"。学校公民教育的路径是生活、制度与启蒙,其基本内容是心育与处世,其实存形态是泛公民教育。泛公民教育的优势在于其与学校生活与工作的内联性与交融性,在于其能够向公民一生与外围社会生活的可推衍性。

采用基于密度泛函理论的第一性原理平面波超软赝势方法,对纯LiZnAs,Mn掺杂的LiZnAs,Li过量和不足下Mn掺杂的LiZnAs体系进行几何结构优化,计算并对比分析了体系的电子结构、半金属性、光学性质及形成能.结果表明新型稀磁半导体Li(Zn0.875Mn0.125)As,Li1.1(Zn0.875Mn0.125)As和Li0.9(Zn0.875Mn0.125)As均表现为100%自旋注入,材料均具有半金属性,Li过量和不足下体系的半金属性明显增强.Li过量可以提高体系的居里温度,改善材料的导电性,使体系的形成能降低.说明LiZnAs半导体可以实现自旋和电荷注入机理的分离,磁性和电性可以分别通过Mn的掺入和Li的含量进行调控.进一步对比分析光学性质发现,低能区的介电函数虚部和复折射率函数明显受到Li的化学计量数的影响.

作为一种新的教学理念,合作学习已经广泛地应用到中小学的课堂教学过程中,但是,实际操作过程中伦理关怀的缺失,使得合作学习往往流于形式而不能起到应有的作用。从伦理学的视角来透视合作学习使得我们更接近于一种哲学的方式来反省该研究的价值与意义。其中,教育的伦理品性是合作学习伦理探究的着眼点;学习的本真含义是合作学习伦理探究的契入点;人是目的则是合作学习伦理探究的落脚点。
