We concluded from the empirical analysis, that the government's purchase expenditure (Gc) has a significant explanatory power on the long-term economic growth. However, extra budget expenditure (YWZ) and the government's fundamental investment (TR) only have substitution effects with limited impact on the long-term economical growth.展开更多

On the other hand, in practice, relevant results are common. The debates among CAM practitioners about the quality and execution of scientific research are important, Therefore, the aim of this review is to gather, synthesize and describe the differentiated methodological models that encompass the complexity of therapeutic interventions. The process of bringing evidence-based medicine into clinical practice in CAM is essential for the growth and strengthening of complementary medicines worldwide.展开更多
