After assuming the Chinese presidency in March 2013, Xi Jinping introduced the new political slogan ＂the Chinese Dream,＂ which he does not only address to the domestic audience but also aims to promote to the world. Since his inaugural trip abroad, Xi has repeatedly speeches when addressing international catchphrase received as much appeal as used the term ＂Chinese Dream＂ in his audiences. However, nowhere has the in Africa. Simultaneously, African academics and other interested parties have observed the promotion of the idea of an African Dream by the Chinese Communist Party （CCP） with great suspicion as they view it simply as a projection of China＇s own foreign policy onto Africa. But what do the Chinese Dream and African Dream actually mean？ How can we make sense out of these terms？ In order to decode or demystify the meaning behind the Chinese Dream narrative in the context of China＇s foreign policy, this paper argues that it is essential to examine how it is constructed and projected to the international audience, in particular to Africa. The Chinese Dream is understood as a narrative which is strategically used by the CCP in order to shape perceptions and behavior of other international actors according to their own agenda. Moreover, the dynamic interactions between the media and politics and how they impinge on the formation and projection of the Chinese Dream and African Dream narrative will also be taken into account.

Association rule mining plays an important role in knowledge and information discovery. Often for a dataset, a huge number of rules can be extracted, but many of them are redundant, especially in the case of multi-level datasets. Mining non-redundant rules is a promising approach to solve this problem. However, existing work （Pasquier et al. 2005, Xu ＆ Li 2007） is only focused on single level datasets. In this paper, we firstly present a definition for redundancy and a concise representation called Reliable basis for representing non-redundant association rules, then we propose an extension to the previous work that can remove hierarchically redundant rules from multi-level datasets. We also show that the resulting concise representation of non-redundant association rules is lossless since all association rules can be derived from the representation. Experiments show that our extension can effectively generate multilevel non-redundant rules.

Emphysematous gastritis (or phlegmonous gastritis) and gastric emphysema (or gastric pneumatosis) are variations of conditions associated with the presence of intramural air in the stomach. The presence of air in the gastric wall is a very rare clinical condition, associated with bacterial infection, increased intragastric pressure from gastric outlet obstruction, gastric mucosal disruption or air dissection from the mediastinum. In adults, this can occur in the setting of instrumentation-related injury, gastric outlet obstruction by gastric, duodenal or pancreatic malignancies or bowel ischemia. Here we describe a case of gastric emphysema related to repeated biliary stenting and partial duodenal obstruction in a patient with inoperable periampullary cancer, and provide the first description of the endoscopic ultrasonographic findings of gastric emphysema in the literature. In our case, endoscopic ultrasound showed a band of bright echogenicity arising from the submucosa layer, representing air in the gastric wall.
