It is based on the 800 corpus examples randomly chosen from the news and sports sections of Guardian. The paper studies the structures preposing, postposing, inversion, extraposition, and dislocation, as well as existential, cleft and passive constructions. It shows that that the news and sports sections of The Guardian are not extensively marked by the use of information-packaging structures.展开更多

The Constitution of the Republic of Indonesia provides a guarantee of religious freedom for every citizen under Article 28 E of the 1945 Constitution. The Constitutional Court, which is required to protect, maintain, and ensure religious freedom for religious minorities, is deemed to fail guarding the right of religious minorities, because in addition to providing a restrictive ruling on a judicial review of the rule of law which is contrary to the basic law, it also fails to interpret legal products under the laws as part of the constitution. The Constitutional Court dysfunction as a guardian of the constitutional rights of religious minorities occurs because of the vacuum of law （recht vacuum）, a narrow interpretation of the constitution by the constitutional judges. The urgency that needs to be addressed is to provide the Constitutional Court with a more extensive authority, which is not limited only to review legal products under laws, but also includes production of Law on Freedom of Religion and Belief for protection in the application of Article 28 E of the 1945 Constitution.展开更多

In August 2014, the Huangchangping Mining Co. in central China＇s Hubei Province began trial production of pyrites without formal approval from the local environ- mental watchdog and dumped untreated waste water on nearby land. The toxic sewage seeped into groundwater that then flowed into the Oianzhangyan Reservoir, taint- ing the drinking water supplies for people living in Wushan and Fengjie counties in Chongqing Municipality neighbor- ing Hubei.展开更多
