The use of a latent class in the specification of the model, allowed detecting two groups of firms according to their specific characteristics： the firm size, the leverage, the dividend yield, and the return on equity （ROE）. The results of affectation equation show that the probability to be in the second group （the most efficient） is more important when the firm size, the dividend yield, and the ROE are high, while a high leverage level decreases the chance to be in the first group （the less efficient）.展开更多

Although heart transplant is the ＂gold standard＂ therapy for HF, due to the limited availability of organs, many patients died when waiting for the transplant. Left ventricular assist device （LVAD）, as a mechanical circulatory support, has become a new light for patients with HF. With the technical advancements, LVADs work not only as a bridge to transplant, but also assist heart recovery and even as a destination therapy in long-term treatment. This observation paper reviewed the development of LVAD and its clinical roles. The challenges and possible solutions in nursing care for pa- tients with LVAD at different stage of implantation were discussed. The healthcare professionals could obtain a better understanding about the LVAD treatment for HF patients.展开更多

At present, global governance and state governance are integrated into a kind of ＂holistic governance＂ based on their interaction and interpenetration. Our understanding of their interplay can be traced back to ideas that developed from ancient Greek and Roman times to the early 20th century. More recently, from the second half of the 20^th century, theories of the interaction between global and state governance essentially revolved around the externalities in state governance and efforts to overcome those externalities by designing an ideal world. Today, the interaction between global and state governance is of great practical significance, serving to inspire the establishment of a global order based on sharing, integration and symbiotic harmony. However, we should also be aware that this interaction may be converted by great powers to the service of their own interests. At present, China can help reshape the global governance order of the 21st century by strengthening its own development, promoting benign interaction between global and state governance, actively harnessing the potential of its state governance capacity and sharing its experience and ideas.展开更多
