The politics of response to terror: the reshaping of community and immunity in the aftermath of 7 July 2005 London bombings

This article explores the politics of response to the 7 July 2005 London bombings, by analysing UK counter-terrorism institutional campaigns in the three years following the attack. By drawing on the interpretive category of community/immunity, the semiotic analysis of counter-terrorism campaigns aims to describe their representation of the political community and citizen in the immediate aftermath of the terrorist attacks. The article argues that the counter-terrorism discourse relies on two contrasting tendencies: on the one hand, the unifying force that brings people together in the name of common values; and on the other, the necessity to weaken communitarian bonds in order to allow the citizen to control and check-up on others, reporting “anything suspicious” to authorities. In these texts, the figure of the citizen surveillant clearly emerges. Surveillance activities are shaped around the representation of the terrorist event, from the image of the terrorist in normal everyday life to the actual attacks. Paradoxically this brings about a mimicry effect. The surveillance action carried out by the citizen and the imagined actions of the preparation of a terrorist attack partially overlap in the way they are described and visually represented.

红七军发展沿革及战斗历程

在邓小平、李明瑞、张云逸等领导下,先后于1929年12月11日和1930年2月1日发动百色起义、龙州起义,成立红七、红八军。红七、红八军在左右江地区坚持斗争10个月后,其主力于1930年10月北上远征,转战7000里,1931年7月到达中央革命根据地,归红一方面军第三军团建制,从此成为中央主力红军的一支劲旅。之后,虽然红七军的部队番号与建制历经多次改变,但红七军英勇善战的优良作风始终如一。     

H5和H7亚型禽流感病毒多重反转录聚合酶链反应快速检测及鉴别方法的建立

参考禽流感病毒(AIV)M基因和HA基因序列设计了3对引物,其中1对为针对不同HA亚型AIV的通用引物,另外2对为分别针对AIVH5和H7亚型的特异性引物。这些引物所扩增的cDNA片段大小分别为244、860和634bp。利用这3对引物,通过对多重RTPCR扩增条件的优化,成功建立了快速检测鉴别AIVH5、H7亚型的多重RTPCR技术。特异性和敏感性试验结果表明,该技术对AIVH5亚型同时扩增出2条大小分别为244bp和860bp的cDNA片段;对AIVH7亚型同时扩增出2条大小分别为244bp和634bp的cDNA片段;对AIVH5和H7亚型混合样品能同时扩增出3条大小分别为244、860和634bp的cDNA片段;对其他AIVHA亚型只扩增出1条244bp的cDNA片段;对其他常见禽病病原扩增均为阴性;该多重RTPCR对AIVRNA、AIVH5和AIVH7亚型RNA的最低检出量分别为10、100和100pg。
