鹅Ⅰ型禽副粘病毒融合蛋白基因3′端cDNA片段的分子克隆

参考禽副粘病毒的融合蛋白基因 (F基固 )cDNA序列 ,设计并合成了 1对引物 ,以分离到对鹅有致病力的Ⅰ型禽副粘病毒GPMV/QY97 1株的核酸 (RNA)为模板 ,用逆转录聚合酶链反应 (RT PCR)对其融合蛋白基因 3′端进行扩增 ,获得了预计的 884bp左右的片段。将该片段克隆进 pGEM TEasy质粒载体 ,获得重组质粒T GPMVF3′ ,采用限制性内切酶和PCR方法对该重组质粒进行鉴定 ,证明所克隆的片段即为目的基因片段 ,这为进一步开展鹅Ⅰ型禽副粘病毒的分子生物学研究奠定了基础     

关于构建安全保卫风险评估课程的思考——《安保风险评估》课程设置构建的必要性与可行性论证

安全保卫风险评估是安保、安防行业的一项核心业务,具有高端性、统领性、综合性等特点.但是,它目前在国内安保行业培训中还没有成为一门系统的教学课程.鉴于此,本文在相关调研、工作实践以及教学活动等准备工作基础上,对安全保卫风险评估课程构建的必要性和可行性进行论证和探讨.在此基础上,逐步探索出整个课程的课程定位、构建思路以及课程内容体系架构,以期对安全保卫专业教学培训乃至整个安保行业的持续发展起到积极的促进作用.     

Mozi: No Aggression,But Universal Love

MOZI (ca.475-395 BC) was one of many philosophers in the volatile Pre-Qin Period (before BC 221 when the State of Qin annexed other six kingdoms and unified China) who were committed to restoring and overhauling the social order.Mozi was a commoner born in the State of Lü (in today’s Shandong Province),but spent most of his life in the State of Song (in present day Henan Province).He studied Confucian theory in his early years,and later established his own school of thought Mohism,which challenges Confucianism on many fronts.Mozi traveled around the states to sell his political ideas to the rulers,who gave him the cold shoulder however.This great thinker never held any high official position in his lifetime.

环境正义与生态帝国主义:基于美国利益集团政治和全球南北对立的分析

环境正义属于环保中的公平正义,与阶级、种族和收入差距直接相关。环境正义运动起源于美国,突出表现为反对环境种族主义的斗争,与民权运动相关联。本文系统考察了美国环境正义运动的历史及相关的国内外研究文献,并运用美国密执安大学社会研究所的《美国全国选举研究》(ANES)民意测验资料,分析了围绕环境正义问题的美国利益集团和政治意识形态冲突。同时,考察了其他一些国家的环境正义问题以及环境正义问题的国际延伸,即生态帝国主义和围绕环境正义的南北政治意识形态冲突。最后,探讨了环境正义和生态帝国主义议题对中国的启示。     

国家监察法立法的若干问题探讨

国家监察法是国家监督领域的基本法,属于宪法性法律.其调整的关系主要包括:国家监察机关与监察对象的关系、国家监察机关与人民代表机关的关系、国家监察机关与党的纪律检查机关的关系、国家监察机关与司法机关的关系以及国家监察机关内部的关系.为了科学合理地调整这些关系,国家监察法应对国家监察机关的组织、职责、权限和监察手段、监察程序,以及对国家监察机关本身的监督、对国家监察对象合法权益的保障和救济机制进行周密的设计和规范,以保证国家监察机关既有效行使反腐败职能,又防止其滥用权力.     

Measurements of the Foramen Magnum and Mandible in Relation to Sex Using CBCT

The purpose of this study was to evaluate pre‐existing CBCT images of a large sample of adult females and males to provide data on foramen magnum and mandibular measures of sexual dimorphism for use as a reference sample in cases of establishing identity in unknown fragmentary skulls. The study group consisted of 161 adult patients. 3D images of the patients were assessed retrospectively. FM measurements were obtained from reformatted axial sections. Six mandibular measurements were taken. According to the results, the study identified four mandibular measurements as final predictors of sex which are as follows: the gonial angle (G‐angle) and ramus length (Ramus‐L), gonion–gnathion length (G–G‐L) and bigonial breadth (BG‐Br). It was found that the cross‐validated grouped overall predictive accuracy was 83.2% for FM and mandible measurements. It could correctly identify males in 77.3% and females in 87.4% of the cases. To assess sexual dimorphism, the gonial angle and ramus, gonion–gnathion lengths, and bigonial breadth of the mandible and sagittal diameter of the FM may be used on CBCT images.
