The Xu-Needleman exponential cohesive law with the fully shear failure mechanism is one of the most popular models. Based on the proposed consistently coupled rule/principle, the Xu-Needleman law with the fully shear failure mechanism is proved to be a non-consistently coupled cohesive law by analyzing the surface separation work. It is shown that the Xu-Needleman law is only valid in the mixed mode fracture when the normal separation work equals the tangential separation work. Based on the consistently coupled principle and the modification of the Xu-Needleman law, a consistently coupled cohesive （CCC） law is given. It is shown that the proposed CCC law has already overcome the non-consistency defect of the Xu-Needleman law with great promise in mixed mode analyses.展开更多

Taking the Wan Clan Ancestral Hall of Sanjiang Town, Nanchang County, Nanchang City, Jiangxi Province for example, this study analyzed its spatial sequence, the planar shape and the facade form, and explained the connotation of "respecting law and discipline rites and advocating moral integrity" contained in the spirit of ancestral halls.展开更多

Applying physical force against children as punishment for unwanted behavior has become a normative part of parents＇ routine interaction with their children, despite the fact that it is forbidden by Israeli law. Psychologists that work with the Muslim Arab population find it difficult to convince parent of the difficulties and conflicts that they create by enforcing corporal punishment on their children. Parents tend to reject professional advice because it is viewed as conflicting with their cultural mentality and traditions and ignore the vast research that proves the ineffectiveness of this type of discipline and the complications that it may lead to. What＇s more, Sharia law, the religious Muslim legal code that governs the lives of Muslim Arabs in Israel, advocates and even encourages corporal punishment. Legislation and further professional intervention is necessary to change this harmful practice and to protect Muslim Arab children.展开更多
