In the construction of new socialist countryside in China, there are also causes for the disadvantaged group status, which are embodied in many aspects. The status is the important root of many problems of agriculture and countryside in China. Changing the farmers' status of the disadvantaged group is the key to constructing the new socialist countryside, deepen-ing the reform in the countryside and realizing the benign social and economic development in the countryside in China.展开更多

The interest protection for the vulnerable people in the water pollution conflicts has attracted attentions of the international scholars. The paper tries to construct the market mechanism which can make the vulnerable people to involve in the emission trading. The vulnerable people can buy American put option in the emission trading market. When the price of the emission runs below the contract price, the vulnerable people can get the benefit through executing the option. When the price of the emission runs above the contract price, the vulnerable people can give up the right. The binomial tree option pricing model can help the vulnerable people to make a decision through the analysis of the worth of the American put option.展开更多

The aim of this study was to explore nurse managers’ perceptions of ethical conflicts when caring for older patients who wish to die. A qualitative method was employed and data were collected by means of a focus group interview with eight nurse managers. The results revealed one theme: A struggle due to responsibility for decision making and four sub-themes:?Understanding the meaning of free will, wondering about how serious the death wish is, providing more worthy elder care and lack of competent healthcare professionals to provide safe care. Nurse managers’ have no structure for bringing ethical conflicts to the attention of their leaders or the next level of the organization. Consequently, they appear to need supervision, support and clear, flexible lines of communication with leadership.展开更多
文摘Though the farmer is the group with the biggest population in China, they are a disadvantaged group. In the construction of new socialist countryside in China, there are also causes for the disadvantaged group status, which are embodied in many aspects. The status is the important root of many problems of agriculture and countryside in China. Changing the farmers' status of the disadvantaged group is the key to constructing the new socialist countryside, deepen-ing the reform in the countryside and realizing the benign social and economic development in the countryside in China.
