Abstract
Purpose
In order to verify the feasibility of different techniques, this chapter further studies the adaptability of two massive straw biomass applications in rural areas in China.
Methodology/approach
The methods of assessing biomass power generation project with Life Cycle Assessment (LCA), survey and field test of one biogas station, and game-theoretic analysis are adopted.
Findings
The following conclusions can be drawn: The air pollution costs account for more than 60% of the total environmental cost, followed by depreciation expense and maintenance fee of 18%, compared to that of biomass power generation at 0.01711 CNY/kWh. The adopted greenhouse sunlight technology of Solar Biogas Plant in Xuzhou, China, raises the inside average temperature by 11.0 °C higher than outside and keeps the pool temperature above 16 °C in winter, ensuring a gas productivity of biogas project in winter up to 0.5–0.7 m3/m3 by volume. This chapter also analyzes the information cost incurred by asymmetric information in biomass power generation via game theory method and illustrates the information structure with game results. It provides not only a foundation for the policy research in promoting straw power generation but also theoretical framework to solve the problem of straw collection.
Social implications
These studies will propose solutions to relevant problems arisen in the running process.
Originality/value
These studies are all based on real cases, field research, and appropriate theoretical analyses, so, they can reduce the relevant costs and promote the application of relevant technologies.

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.

Abstract
Due to the increasing size and complexity of construction projects, construction engineering and management involves the coordination of many complex and dynamic processes and relies on the analysis of uncertain, imprecise and incomplete information, including subjective and linguistically expressed information. Various modelling and computing techniques have been used by construction researchers and applied to practical construction problems in order to overcome these challenges, including fuzzy hybrid techniques. Fuzzy hybrid techniques combine the human-like reasoning capabilities of fuzzy logic with the capabilities of other techniques, such as optimization, machine learning, multi-criteria decision-making (MCDM) and simulation, to capitalise on their strengths and overcome their limitations. Based on a review of construction literature, this chapter identifies the most common types of fuzzy hybrid techniques applied to construction problems and reviews selected papers in each category of fuzzy hybrid technique to illustrate their capabilities for addressing construction challenges. Finally, this chapter discusses areas for future development of fuzzy hybrid techniques that will increase their capabilities for solving construction-related problems. The contributions of this chapter are threefold: (1) the limitations of some standard techniques for solving construction problems are discussed, as are the ways that fuzzy methods have been hybridized with these techniques in order to address their limitations; (2) a review of existing applications of fuzzy hybrid techniques in construction is provided in order to illustrate the capabilities of these techniques for solving a variety of construction problems and (3) potential improvements in each category of fuzzy hybrid technique in construction are provided, as areas for future research.
