The rational capital structure could reduce the cost of capital and plays an important role in managing a company. Thus this paper, based on the real estate listed companies on Shenzhen and Shanghai stock markets, analyzes the factors which influence capital structure, such as profitability, size, collateral value of assets, growth, stockholder’s equity, concentration degree of control power, ownership attribute, and applied statistics tools used to help the real estate listed companies optimize the structure of capital.展开更多

Agency relationship of social security Fund involves four agents, among which the entrustment between National Council for Social Security Fund （SSF） and social security fund management company is a key element. Due to information asymmetry phenomenon in the entrustment management process, the fund needed to establish the appropriate entry and exit criteria, and relying on a third party to avoid agency risks.展开更多

The emergency management of these patients is challenging and controversial. The key issues in its management are identifying the site（s） of hemorrhage and then controlling the bleeding. Management of hemodynamically unstable patients with pelvic fracture requires a multidisciplinary team. The issues addressed in this management algorithm are diagnostic evaluation, damage controlresuscitation, indications for noninvasive pelvic stabilization, preperitoneal pelvic packing and the critical decisions concerning surgical options and angiography. This review article focuses on the recent body of knowledge on those determinations.展开更多

We define D to be an S-＊w-principal ideal domain if for each nonzero ideal I of D, there exist an element s ∈ S and a principal ideal （c） of D such that sI （c） In this paper, we study some properties of S-＊w-principal ideal domains. Among other things, we study the local property, the Nagata type theorem, and the Cohen type theorem for S-＊w-principal ideal domains.展开更多
