大鼠肝细胞DNA含量与早期死亡时间关系的图像分析研究

实验选择 15只大鼠 ,处死后 ,在 2 4h内 ,每隔 1h取肝组织块进行细胞学涂片、福尔马林液固定、Feul gen染色、自动图像分析仪测量、统计学处理数据。结果表明 ,肝细胞DNA含量在死后 2 4h内 ,随死亡时间的延长而较有规律的下降。其中积分光密度、平均光密度、异形指数是用来研究死亡 2 4h内肝细胞DNA降解规律 ,并准确推断死亡时间的较好指标。     

Precarity,Cognitive (Non-)Resistance and the Conservative Working Class in China

ABSTRACT

Workers’ resistance is crucial to understanding how the working class respond to the growing labour precarity in post-socialist China. The labour studies literature posits that inequality and volatile capital movements increase workers’ precarity and lead to stronger labour resistance, such as strikes. However, workers’ cognition as an integral part of resistance has been rarely studied. This article examines cognitive resistance by Chinese workers from different tier cities by looking at their social trust, class identity, understanding of policies and class solidarity. Despite capital movements and precarity causing more labour unrest, it does not necessarily lead to a stronger cognitive resistance. While inequality and precarity are greater in the more developed megacities with a shifting capital favourability, workers in megacities display a more conservative cognitive resistance than those from the lower-tier cities. This study of workers’ cognitive resistance provides insight into the future of the Chinese labour movement. It argues that the working class’s current cognitive non-resistance suggests that even if a window of opportunity were to appear in the wall of state oppression, workers are not cognitively prepared to coalesce into a coherent social movement that would bring about transformative changes.     

2006年中期选举对美国外交内政的影响

由于伊拉克问题的独特影响,美国2006年中期选举可谓是一次外交决定内政的选举。民主党的全胜使得这次选举成为1994年以来最重要的一次中期选举,它不仅决定了美国国会新的政党分野与权力布局,而且对美国的外交内政都产生了较大影响。外交方面,在可预见的一段时间内,国会的外交政策理念将呈现右倾趋势;伊拉克政策可能会出现一定程度的微调,但不会出现戏剧性的剧变;对华政策也可能出现一定的波动。内政方面,其直接影响主要体现在国内经济政策、非法移民政策与国内社会政治思潮等方面。     

论当前广西与泰国的经贸关系——兼谈与云南和泰国经贸关系的比较分析

在发展同泰国的经贸关系中,广西与云南具有许多相似点,例如广西与云南的区位优势都很明显,都是中国通向东南亚的桥头堡,与泰国距离都很近;根据专家的研究,云南的傣族、广西的壮族与泰国的民族都是"同源异流",双方习俗相似、语音相近,两省区都有不少华侨华人在泰国.更重要的是,云南与广西在产业结构上都是工业不发达以农业为基础的省份,两省区与泰国产业结构趋同和产业水平相近,产业内贸易在双方贸易总额中所占比重很大.在这样相同的背景下,对云南与泰国的经贸关系和广西与泰国的经贸关系进行比较分析,找出其中的差距,借鉴云南的经验,挖掘自身的优势,对于进一步推动广西与泰国的经贸关系的发展无疑具有重要的意义.
