Since becoming head of the Communist Party in China in late 2012, Xi Jinping has accrued an impressive raft of titles. He has been compared to the founder of the regime, Mao Zedong, and is seen by some as sitting at the centre of a network of different power sources. But is power as personalised as this model makes out in contemporary China, with all its complexity and diversity? And can one person really rule the continental sized country in this paternalistic way? This article argues that Xi's powers are intrinsically linked with the organisation that he leads and which his power is sourced in – the Party itself. Far from him being the emperor of modern China, it is the Communist Party which acts as the all-seeing, all-powerful ruler. In this model, Xi is its servant, not its master.  相似文献

NEW CHALLENGES     
<正>A diverse range of global issues puts Chinese diplomacy to the testThe National People’s Congress,China’s top legislature,opened its annual full session on March 5.Both the Report on the Government Work delivered by Premier Li Keqiang at its opening and the press conference held on March 8 by Foreign Minister Wang Yi on its sidelines made one thing abundantly clear:What happens inside China is linked to and profoundly affects the outside world.Likewise,  相似文献

This article discusses the role of the private company in the fight against terrorism. It argues that the private company has become politically important to counterterrorism efforts, but the economic logic guiding the risk thinking of private companies is hardly compatible with the aim of providing national security. By examining whether and in what manner the risk of terrorism is considered a corporate responsibility, the article seeks to answer whether and how the political role ascribed to the company finds any resonance in the risk practice of private companies. The article approaches this question by examining how Danish food and infrastructural companies conceptualize the relationship between terrorism risks and corporate responsibility. It demonstrates that a distinction between safety and security discursively facilitates an exclusion of national security concerns from the concept of Corporate Social Responsibility (CSR) and thereby works to deresponsibilitize the company in the fight against terrorism.  相似文献

Abstract: The choice of reagents for presumptive tests for blood, and subsequent extraction methodologies, can significantly affect both the quantity and quality of purified DNA. Blood samples directly tested with Hemastix® yielded <1% of the DNA recovered from untested samples when purified using the Qiagen BioRobot® EZ1 and EZ1® DNA Investigator kit. Full short tandem repeat profiles were obtained from both tested and untested samples, suggesting that the Hemastix® reagent(s) affect DNA binding, rather than produce DNA damage. The Hemastix® inhibition of DNA yield could be overcome by the addition of MTL buffer to the sample prior to extraction. Laboratories may wish to modify current procedures for extracting blood samples, utilize other extraction/purification methodologies, or inform their submitting agencies to avoid direct exposure of questioned bloodstains to Hemastix® reagents.  相似文献

The current study investigates the removal of soft tissues from mice and rats by the use of three different proteases and one lipase from Novozymes A/S. The results demonstrate the enzyme maceration to be remarkably fast (1-3 h) compared to the traditional warm-water procedure, which requires up to several days. In addition, the enzyme maceration eliminates the odor problem associated with the traditional procedure. It is shown that stirring of the enzyme maceration bath is the main factor which determines the speed of the maceration. For mice, the time required for enzyme maceration can vary from 1 to 8 h depending on the stirring speed. The method investigated here allows preparation of skeletal material in an essentially odorless way within a matter of hours, making the method useful in particular for forensic science, private conservation workshops, and educational purposes.  相似文献
