Tailoring Representative Democracy to the European Union: Does the European Constitution Reduce the Democratic Deficit?

Abstract Even if the institutions of representative democracy that have developed in the nation‐state context cannot be simply transposed to the European Union, for practical and normative reasons they do provide the main starting point for any reflection on the EU's ‘democratic deficit’. This article draws upon the Constitution prepared by the European Convention to reconstruct the concept of representative democracy in the EU. Drawing on the proposals put forward, it identifies two distinctive challenges that need to be overcome if the concept of representative democracy is to be successfully applied to the EU: the multilevel character of the polity and the shift of the centre of political gravity from legislative to executive politics. The article then examines the extent to which the institutional proposals contained in the Constitution go to meet these two challenges and also highlights some aspects in which these proposals fall short.     

新课程理念下公安院校普体课程的改革

公安院校普体课教学还存在一些问题。在新课程理念下,其改革应注意课程内容与设置多样化和具有弹性,注重不同水平学习内容的衔接;提高学生上课的自由度,课程评价注重学生的发展,采用多元评价;转变教师观念,完善师资结构,从而把健康第一的目标落实到每一个学生身上。     

对公安机关应对流浪乞讨问题的思考

收容救助制度取代收容遣送制度后,城市中愈演愈烈的流浪乞讨现象引发了现实与潜在的社会秩序和公共安全问题。作为维护社会治安和公共安全的主要行政部门———公安机关,有介入流浪乞讨问题治理的必要,尽管在这一过程中公安机关仍面临诸多特殊困难。解决思路包括充分运用已有的法律法规、设立“禁乞区”、积极促进流浪乞讨问题之“综合治理模式”的建立。     

非洲猪瘟CD2v胞外区基因片段的真核表达及其多克隆抗体的制备

本研究利用真核表达系统表达非洲猪瘟病毒的CD2v胞外区蛋白,研究其免疫特性,制备多克隆抗体并研究其性质,为研发特异性单抗奠定数据基础。以非洲猪瘟病毒Wuhan2019-1株(GenBank:MN393476.1)为模板,合成CD2v胞外区基因序列,并将其克隆至真核表达载体pCAGGS载体中,获得pCAGGS-CD2v胞外区重组质粒。经酶切和测序鉴定后,将重组质粒转染293F细胞,获得重组胞外CD2v蛋白(简称His-CD2v)。用Ni-NTA柱纯化His-CD2v,并以此为抗原免疫BALB/c小鼠制备多克隆抗体,利用ELISA和间接免疫荧光对多克隆抗体进行鉴定。结果显示,(1)His-CD2v融合蛋白在293F中以可溶形式表达,SDS结果显示,相对分子质量约为35~80 ku的弥散带;(2)融合表达的His-CD2v能与阳性血清反应,与对照不反应;(3)HisCD2v制备的多抗效价最高达1∶218700,且能与阳性血清竞争性结合CD2v抗原。上述结果表明,His-CD2v融合蛋白的表达及其多抗的成功制备,为进一步筛选CD2v特异性单抗及研制竞争ELISA试剂盒,为非洲猪瘟感染与免疫鉴别方法的建立奠定了坚实的基础。

鼻骨骨折螺旋CT3D成像与X线片对比研究

目的 评价螺旋CT扫描三维重建成像与X线摄片对比对鼻骨骨折法医学鉴定的价值。方法 使用SOMATOM BALANCE 1s螺旋CT机，对32例复杂鼻部外伤者2mm／2mm扫描，常规进行最大密度投影法(MIP)、多平面重建(MPR)、表面覆盖法(SSD)、容积成像(VR)方式。全貌显示受伤鼻骨骨折影像，并与常规鼻骨摄片比较。结果 螺旋CT三维成像纠正3例X线照片的假阳性和6例诊断骨折类型不准确。结论 螺旋CT三维重建对诊断复杂鼻骨骨折块数目、移位，以及骨折类型优于X线摄片。     

关于“法理分析”和“法律分析”的断思

经过二十余年的法学复兴,中国学者开始重视法学方法论的研究,其中以法律分析、法理分析、法理透视、法哲学思考命名的论文日益增多.这表明学者已认识到法学乃至于法理学是一门相对独立的学科,其学科知识的体系性、思维方式的独特性已受到程度不同的关注.但是,那种简单贴标签式的命题值得推敲.本刊编辑陈立风与山东大学法理学专业的部分师生举办对法律分析和法理分析进行反思的小型学术沙龙,展开了对话式的探讨.现刊载部分,意在引起学界对此问题的共鸣.
