The BRICs Come of Global Age

The world is rapidly evolving on many fronts. Brazil, Turkey and other emerging powers are taking their own initiatives and building their own global links outside the old frameworks of the G‐8, the United Nations Security Council and NATO. The “third way” politics of Tony Blair that embraced globalization from the left of center in Britain has given way to the Tory party once again. Just as recovery from the financial crash seemed on the horizon, Europe's sovereign debt crisis has erupted. The historically unprecedented pace and scale of urbanization in China is transforming the politics of the Communist Party. President Lula of Brazil, former US treasury secretary Henry Paulson, Singapore's foreign minister George Yeo and others take stock of these manifold developments.     

PRESTIGE OF JOURNALS IN CRIMINOLOGY AND CRIMINAL JUSTICE

The prestige of professional journals is an important element in the academic world because of the relationship of journal prestige to the careers of individuals and to the reputations of academic institutions. This study investigates the system of journal prestige in the field of criminology and criminal justice, using the ratings of professional journals obtained from a sample of respondents who are members of professional associations in criminology and criminal justice. The results show that there is a relatively high degree of agreement about the relative prestige of journals in the field, despite the fact that criminology and criminal justice is a multidisciplinary field involving professionals from a wide variety of occupational settings.     

辛硫磷对大鼠肝细胞凋亡的影响

通过给大鼠肝细胞培养液中加入辛硫磷(染毒终浓度分别为3、10、30、100和300 μmol/L)染毒,于12、24 h后用流式细胞仪分别测定细胞凋亡率、细胞死亡率和细胞内活性氧(ROS)水平,并在扫描电镜和荧光显微镜下观察细胞凋亡情况,研究了辛硫磷对原代培养大鼠肝细胞凋亡的影响.结果显示,辛硫磷具有明显的细胞毒性,在3～100 μmol/L范围内随着染毒剂量的增大和染毒时间的延长,细胞死亡率、凋亡率和ROS水平显著升高,且发生了明显的细胞凋亡的形态学变化;但300 μmol/L辛硫磷培养24 h,肝细胞凋亡率和ROS水平下降,死亡率升高.表明辛硫磷对肝细胞有直接的毒性作用,并通过产生ROS诱导了肝细胞凋亡.     

现行国际秩序演变的方向与中国的选择

中国与西方国家使用不同术语来描述现行国际秩序,双方对国际秩序的认识也确实存在明显差异。但是仔细分辨之后,又能发现中国与西方的国际秩序观实际上重叠之处远大于差异之处。2008年金融危机后,国际秩序开始发生重大变化。2020年的新冠肺炎疫情进一步加剧了这一变化。一方面国际格局的变化导致西方国家认为现行国际秩序遭到新兴大国挑战,另一方面西方国家内部对全球化的不满则导致一些西方国家主动挑战现行国际秩序。当前国际秩序演变出现了自由主义色彩消退、民族国家作用逐渐强化的趋势,这将导致中国与西方国家在某些方面的竞争加剧,但也有可能导致双方对国际秩序演变方向的认知差异缩小。只有准确理解国际秩序演变的这些脉络,中国才能更好地进行战略和政策抉择以趋利避害。
