Abstract
Purpose
Public hospitals in China usually rely on revenues from medical services and medications to compensate for major costs given their nonprofit nature. The lack of government subsidies and unreasonable prices of medical services have led to high medical costs and unbalanced reimbursement system for public hospitals. There is a critical need of research on improvement of reimbursement system that will create positive effect on China’s health-care system. This paper aims to focus on four dimensions of stakeholders (government, patients, medical insurance agencies and social organization) and six major expenditures to explore reimbursement scheme for public hospitals in China with the purpose of relieving unbalanced income and expenditure of hospitals, avoiding medication markups and reducing medical expenses from patients.
Design/methodology/approach
In this paper, the authors study reimbursement scheme for public hospitals from the perspective of four dimensions of stakeholders and how stakeholders reimburse six major expenditures of hospitals. A total of 128 effective samples were collected from financial data of 32 public hospitals through 2009-2012. This paper analyzes the econometric models of the selected revenue and expenditure. This paper analyzes the econometric models of the selected revenue and expenditure using linear regression. The linear relationship between each cost and different types of incomes (i.e. reimbursements from government, patients, insurance agencies and social organization) is analyzed before and after cancelling the medication markups.
Findings
Results from empirical research verify that government reimbursement is insufficient, and using medication markups to compensate for medical service costs has become a serious problem for China’s public hospitals. To avoid the medication markups and improve the reimbursement scheme, government should reimburse labor cost, fixed assets cost and research cost; patients and medical insurance agencies should reimburse the costs of medical service, medication and administration/operations; and social organization should supplement the fixed assets cost.
Originality/value
In this study, the authors defined and classified stakeholders of reimbursement scheme for public hospitals in China, which help understand the roles and effects that different stakeholders can play in compensation. Along with the proposed reimbursement scheme framework, this study will help make effective implementation of new health-care reform program in China.

Abstract
Purpose
Hydro-viscous drive (HVD) clutches are widely used in equipment requiring soft start, such as fans and pumps, to transmit torque and adjust speed by changing the gap distance between friction pairs. This paper aims to propose a novel two-parameter evaluation method for HVD during the mixed lubrication stage. The objective is to develop an effective model that establishes the relationship between these parameters and the actual surface topography.
Design/methodology/approach
In the presented methods, the fractal features of the real manufacturing surface are calculated based on the power spectrum function by the ultra-depth three-dimensional microscope. After that, the hybrid friction model of the friction plate is established based on mixed elasto-hydrodynamic lubrication theory, boundary friction model and fractal theory. Then the torque and load bearing characteristics of the clutch are obtained, and the influences of the surface fractal features are investigated and discussed. Finally, the Weierstrass–Mandelbrot function is adopted for the surface topography characterization and evaluation.
Findings
The results indicate that the proposed method exhibits good accuracy, while the speed difference between the friction pair exceeds 2,500 rpm. It is concluded that this paper proposed a way to evaluate the torque and loading capacity of HVD considering the real manufacturing surface topography and is helpful for surface optimization.
Originality/value
The originality and value of this study lie in its development of a novel torque and load bearing capacity evaluation method for HVD in mixed lubrication stage, considering manufacturing surface topography and describing the real manufacturing surface.

Abstract
Purpose
The purpose of this paper is to explore and compare haze-related content between traditional and social media in China by applying agenda-setting theory and the extended parallel process model (EPPM). Specifically, this paper examines the correlation between the two forms of media in terms of the ranking of the attributes of haze (i.e. the EPPM components) and the interrelationships among the attributes.
Design/methodology/approach
Content analysis and semantic network analysis were employed to address the research aims.
Findings
The results revealed that more than half of the total messages on both types of media reflected the EPPM components, either threat or efficacy information. However, the imbalance between the threat and efficacy information was more prominent in the haze-related content presented in the People’s Daily than it was on Weibo. In addition, the results from a Spearman’s rank-order correlation and a quadratic assignment procedure (QAP) indicated that there was no significant correlation between the People’s Daily and Weibo in terms of the rankings of the attributes of haze (i.e. the EPPM components) or the interrelationships among the attributes.
Originality/value
This study is the first to apply a theoretical approach to examine and compare the nature of haze-related messages on traditional and social media.

Abstract
Purpose
The purpose of this paper is to develop a capped barrier option framework to consider the politically preferential treatment for bank loans incentivized by government capital injections and calculate loan-risk sensitive insurance premiums.
Design/methodology/approach
This paper takes a capped barrier option approach to the market valuation of the equity of the bank and the liability of the deposit insurer. The cap demonstrates the dynamics of a politically connected borrowing firm’s asset and highlights the truncated nature of loan payoffs. The barrier addresses that default can occur at any time before the maturity date. The bank participating in a government capital injection program is required to fund the politically connected firm that has preferential access to financing.
Findings
Political connection as such makes the bank more prone to risk taking at a reduced interest margin, produces greater safety for the bank owing to government capital injections, and leads to increasing the fair deposit insurance premium. The positive effect of political connection on the deposit insurance premium, which ignores the cap and the barrier yields significant over-estimation.
Originality/value
The study on the politically connected borrowing firm shows that political connection is likely to affect the distressed bank’s performance, yielding the political-connection cost of a reduced bank interest margin and the political-connection benefit of a reduced bank equity risk, contributing the literature on political connection and bank bailout.

Abstract
Purpose
The purpose of this study is to propose a generalized integral transform technique (GITT) to investigate the bending behavior of rectangular thin plates with linearly varying thickness resting on a double-parameter foundation.
Design/methodology/approach
The bending of plates with linearly varying thickness resting on a double-parameter foundation is analyzed by using the GITT for six combinations of clamped, simply-supported and free boundary conditions under linearly varying loads. The governing equation of plate bending is integral transformed in the uniform-thickness direction, resulting in a linear system of ordinary differential equations in the varying thickness direction that is solved by a fourth-order finite difference method. Parametric studies are performed to investigate the effects of boundary conditions, foundation coefficients and geometric parameters of variable thickness plates on the bending behavior.
Findings
The proposed hybrid analytical-numerical solution is validated against a fourth-order finite difference solution of the original partial differential equation, as well as available results in the literature for some particular cases. The results show that the foundation coefficients and the aspect ratio b/a (width in the y direction to height of plate in the x direction) have significant effects on the deflection of rectangular plates.
Originality/value
The present GITT method can be applied for bending problems of rectangular thin plates with arbitrary thickness variation along one direction under different combinations of loading and boundary conditions.

This study aims to research properties of Cu/SAC0307 mixed solder balls/Al joints with different bonding temperature under ultrasonic-assisted.
Abstract
Purpose
This study aims to research properties of Cu/SAC0307 mixed solder balls/Al joints with different bonding temperature under ultrasonic-assisted.
Design/methodology/approach
A new method that 1 mm Zn particles and Sn-0.3Ag-0.7 (SAC0307) with a particle size of 25–38 mm were mixed to fill the joint and successfully achieved micro-joining of Cu/Al under ultrasonic-assisted.
Findings
The results indicated that when the bonding temperature was 180°C, there was only one layer of CuZn5 intermetallic compounds (IMCs) at the Cu interface. However, when the bonding temperature was 190°C, 200°C and 210°C, the Cu interface IMCs had two layers: for one layer, the IMCs near the Cu substrate were Cu5Zn8 and for another layer, the IMCs near the solder were CuZn5. In addition, the thickness of the Cu interfacial IMCs increased with the bonding temperature. In particular, the thickness of IMCs at the Cu interface of the Cu/Al joints soldered at 210°C was 4.6 µm, which increased by 139.6% compared with that of the Cu/Al joints soldered at 180°C. However, there was no IMC layer at the Al interface, but there might be a Zn–Al solid solution layer. The shear strength of Cu/Al joints soldered at 180°C was only 15.01 MPa, but as the soldering temperature continued to increase, the shear strength of the Cu/Al joints increased rapidly. When the soldering temperature was 200°C, the shear strength of the Cu/Al joints reached the maximum of 38.07 MPa, which was 153.6% higher than that at 180°C. When the soldering temperature was 180°C, the fracture of Cu/Al joints was mainly on the Al side. However, when soldering temperature was 190°C, 200°C and 210°C, the fracture of Cu/Al joints was mainly broken in the Zn particles layer.
Originality/value
A new method that 1 mm Zn particles and Sn-0.3Ag-0.7 (SAC0307) with a particle size of 25–38 mm were mixed to fill the Cu/Al joint at 210°C.

Abstract
Purpose
This paper aims to develop a barrier cap option model, i.e. a cap option model where default can occur at any time before the maturity date, to evaluate the equity and the default risk of a bank. The model implies the bank as a liquidity provider that one institution carriers out both lending and deposit-taking functions under the same roof. This paper studies the impacts of demand deposits and capital regulation on the optimal bank interest margin, i.e. the spread between the loan rate and the deposit rate.
Design/methodology/approach
This paper characterizes the bank’s equity value by a barrier cap option framework. In the model, default can occur at any time before the maturity and loan markets are imperfectly competitive.
Findings
This paper has two main results. First, increases in demand deposits reduce the bank’s interest margin and further increase the bank’s default risk. The negative effect on the optimal bank interest margin which ignores the barrier leads to significant overestimation; the positive effect on the default risk which ignores the barrier leads to underestimation. Second, the same pattern of capital regulation as previously applies. Capital regulation as such makes the bank more prone to loan risk-taking, thereby adversely affecting the stability of banking system.
Originality/value
This paper reintroduces the knock-out value and bank interest margin determination within a synergy banking function to the cap option model. The results confirm the need to model bank equity as a barrier cap option and demonstrate its usefulness in capital regulation.

Abstract
Purpose
The purpose of this paper is to develop a theoretical framework to answer the following question: What are the consequences of sunflower behavior as well as spread behavior for how asset-liability management is administrated in a life insurance company?
Design/methodology/approach
This paper takes into account the following: the chief executive officer (CEO) of a life insurance company confirms the board of directors’ belief – the preference of the like of higher return relative to the dislike of higher risk; the authors call such behavior sunflower management; the life insurance policyholder is entitled to a guaranteed interest rate and a participation percentage of the company’s investment surplus; and the authors examine the optimal insurer interest margin, i.e., the spread between the loan rate and the guaranteed rate.
Findings
Sunflower management translates into lower utility for the CEO and makes the CEO more prudent to risk-taking at an increased insurer interest margin for the provision of life insurance contracts. The effect of the guaranteed rate on the margin is ambiguous and depends on the level of guarantee itself. An increase in the participation level decreases the CEO’s loan risk-taking at an increased margin. It is shown that a trend toward higher return like of the board’s belief produces a corresponding trend toward the CEO’s decreasing risk-taking when the return like is revealed strongly. The results indicate that sunflower management as such is an important determinant in ensuring a safe insurance system.
Originality/value
This is the first paper to construct a contingent claim model to evaluate the expected value of the CEO’s utility function defined in terms of the equity returns and the equity risks of a life insurance company. The model explicitly considers CEO sunflower behavior, CEO spread behavior and the limited liability of shareholders.
