In this paper, a modularized code framework of diagenetic model was proposed as a diagnostic tool to fit the porewater profiles in marine sediments. Based on the conservation principle of the finite volume method, we combined the discretized diagenetic equations with various geochemical reactions, including but not limited to methanogenesis, sulfate reduction, etc.. The code was organized in object-oriented FORTRAN and verified with literature parameters, which proved its robustness and effectiveness. Finally, three different sites（IODP Expedition 311 Site U1327, UBGH2-1_1, ODP Leg204 Site 1245） are exemplified as case studies.展开更多

We investigated conflict between members of the same culture （intra-cultural conflict） and conflict between members of different cultures （inter-cultural conflict）. Intra-culturally, both American and Chinese noted self-interest as an important dimension of the cause of conflict. Inter-culturally, both American and Chinese noted cultural differences as an important dimension of the cause of conflict. The similarities between the American and Chinese dimensions were more striking than the differences. The intra-cultural findings reinforce the validity of early Western conflict theories--focusing on self-interest vs. other interest. The inter-cultural findings are partially consistent with intergroup theory and introduce new elements to conflict theory.展开更多
