Abstract
Purpose
The numerical simulation of dispersed-phase evolution in injection molding process of polymer blends is of great significance in both adjusting material microstructure and improving performances of the final products. This paper aims to present a numerical strategy for the simulation of dispersed-phase evolution for immiscible polymer blends in injection molding.
Design/methodology/approach
First, the dispersed-phase modeling is discussed in detail. Then the Maffettone–Minale model, affine deformation model, breakup model and coalescence statistical model are chosen for the dispersed-phase evolution. A general coupled model of microscopic morphological evolution and macroscopic flow field is constructed. Besides, a stable finite element simulation strategy based on pressure-stabilizing/Petrov–Galerkin/streamline-upwind/Petrov–Galerkin method is adopted for both scales.
Findings
Finally, the simulation results are compared and evaluated with the experimental data, suggesting the reliability of the presented numerical strategy.
Originality/value
The coupled modeling of dispersed-phase and complex flow field during injection molding and the tracing and simulation of droplet evolution during the whole process can be achieved.

Abstract
With the rapid development of China’s urbanisation and market economy, municipal solid waste (MSW) generation is increasing dramatically. In response to the threat of environmental pollution and the potential value of converting waste into energy, both the government and the public are now paying more attention to MSW treatment and disposal methods. In 2014, 178.6 million tonnes of MSW was collected at a safe treatment rate of 84.8%. However, the treatment methods and the composition of MSW are influenced by the collection area, its gross domestic product, population, rainfall and living conditions. This chapter analysed the MSW composition properties of Lhasa, Tibet, compared with other cities, such as Beijing, Guangzhou and so forth. The research showed that the moisture content of MSW in Lhasa approaches 31%, which is much lower than the other cities mentioned previously. The proportion of paper and plastics (rubbers) collected was 25.67% and 19.1%, respectively. This was 1.00–3.17 times and 0.75–2.44 times more than those found in Beijing and Guangzhou, respectively. Non-combustibles can reach up to 22.5%, which was 4.03–9.11 times that of Beijing and Guangzhou, respectively. The net heating values could reach up to 6,616 kilojoule/kilogram. The food residue was only half the proportion found in other cities. Moreover, the disposal method applied in each city has also been studied and compared.

Abstract
This study investigates the economic content of the two firm‐specific characteristics, size and book‐to‐market equity. Size is found to be significantly related to a combination of betas on all of the macro variables proposed in this research. Its significance persists through out the entire sample period. This provides further evidence that size is a proxy for pervasive risk factors in the stock market. The support for book‐to‐market equity’s role as a risk proxy is also evidenced, however to a lesser extent. Securities are then sorted into size and book‐to‐market equity portfolios and their effects on investment decisions are examined in the context of macro variables. Important investment implications are drawn based on the findings.

Abstract
Purpose
The purpose of this paper is to examine what use has been made of civil recovery legislation in the first three years of its existence and to explain the legal issues which have been raised before the courts so far. It also examines the legislative and non‐legislative changes to the civil recovery scheme since it is commencement in 2003.
Design/methodology/approach
The paper uses examples from amongst those cases initiated by the Assets Recovery Agency and draws on both reported and unreported court rulings.
Findings
The civil recovery cases brought against property by the Assets Recovery Agency may be classified into six categories: where a potential criminal defendant has died and is therefore beyond prosecution; where a criminal defendant has been acquitted; where a criminal defendant was convicted but the confiscation hearing failed; where the respondent is not within the jurisdiction; where the owner of the property is uncertain; and where a respondent is unprosecutable due to insufficient evidence.
Originality/value
The paper provides a useful framework for law enforcement agencies which are considering what type of cases they may useful refer for possible civil proceedings by the Agency. The paper also sets out for practitioners a useful summary of the civil recovery jurisprudence which has so far developed.

Abstract
Purpose
The purpose of this paper is to present a new method and model for determining the optimal decision-making for the pricing strategy to the Fuji apple in Shaanxi of Chain which is representing fresh agricultural products under the e-commerce environment.
Design/methodology/approach
Considering the rapid development of information technology as well as internet that actually motivate the e-commerce, Fuji apple is a distinctive product in China’s Shaanxi; its sales channels have extended to online sales under the wave of e-commerce. Internet trading platforms make it possible to trade online in real time between suppliers and customers who live in different geographical areas. In this paper, the authors study how to price online to maximize the total revenue. The challenge is to optimally price two different qualities of apple. Based on the consumer surplus theory, the authors use the method that builds the function of the relationship between the proportion of consumers purchasing different qualities of products and price.
Findings
This paper presents a generalized model to determine the optimal pricing that maximizes the total revenue of a fruit grower over a finite planning horizon. The authors divided discount into two intervals and discussed the optimal discounting and pricing at both intervals. Then they determined the optimal pricing strategy for Fuji apple in Shaanxi of Chain under the e-commerce environment.
Originality/value
This paper makes up for the lack of existing studies of pricing under the e-commerce environment. A new method and approach to the traditional pricing strategy is established and applied to a management decision-making problem with Chinese characteristics in reality.

Abstract
The paper advances the argument that social capital operates on both the supply and demand sides of the labor market. Organizations have significant needs for employees with social capital capacity and skills as they do with human capital. We articulate a theory on why organizations have such needs and how social capital may be differentially and strategically deployed to different positions. Specifically, three types of positions (the top positions, the edge positions, and the exchange-oriented positions) are identified with such needs. We formulated two hypotheses derived from the theoretical articulation: (1) the deploying hypothesis – organizations are expected to strategically recruit and deploy workers with social capital capacity and skills to such key internal and edge positions and (2) the institutional contingency hypothesis – organizations in the more competitive environment (e.g., the private sector) are more likely to show such differential deployment than those in the less competitive environment (e.g., the state sector). The hypotheses were subjected to an empirical examination with a set of firm data from China. Both hypotheses were confirmed. Further, we also found evidence for differential deployment of human capital (education and experience) and hierarchical capital (statuses of prior positions and organizations) in different sectors. We discuss the implications of the theory and findings for future research on organizations in different economic sectors beyond China and how a theory of deploying various types of capital – social capital, human capital, and hierarchical capital – in different economic sectors may be developed.

Abstract
Purpose
This chapter provides a thorough historical overview of policies that have governed and guided scientific research in China since 1949 and illustrates changes in scientific publications that accompanied these policy reforms and programs.
Design
We divide this historical period into four stages, each with distinct R&D policies: (1) 1949–1955, a period of socialist transformation; (2) 1956–1965, a period of struggle for higher education and research development in a rapidly changing political environment; (3) 1966–1976, the lost decade of the Cultural Revolution; and (4) 1976–present, a period when major national policies have significantly promoted scientific research in China. We use the SPHERE project’s comprehensive historical dataset based on Thomson Reuters’ Web of Science and data from a set of research universities in China to analyze changes in scientific publication rates concurrent with these policy reforms and programs.
Findings
The analysis suggests a tight connection between national policy and scientific research productivity in higher education. The central government controlled scientific research through direct administration in early periods and has guided research activities through funding specific programs in recent decades. Due to their resource dependency on the central government, higher education institutions have been quite responsive to the common goals set by the central government. As a result, what is measured tends to be accomplished.
Originality/value
The chapter provides an in-depth description about the rise of higher education and science in China and produces recommendations for future development.
