It discusses the roles of the specific NGOs in dealing with black carbon in the Arctic region from the perspective of global governance to gain insights to guide our involvements in the Arctic affairs and shipping in the region by taking the advantages of NGOs' influence on the proceedings of international negotiations, our national policy development, the improvement of industrial practices and public perceptions.展开更多

Facing the increasing trend of cancer incidence and mortality, China issued and implemented "three-early(early prevention, early diagnosis and early treatment)" national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations(NGOs) take over the role of government in the field of cancer prevention and treatment. American Cancer Society(ACS) made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control(UICC), Cancer Council Australia(CCA), and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association(CACA) as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.展开更多
