Abstract
Purpose
Aiming at the cavitations and noise problem of hydraulic cone valve and based on the radial force analysis of the valve core, the radial deviation of the spool is considered to obtain the changing rules of cavitations and noise.
Design/methodology/approach
The solid model of the internal flow field of cone valve is established. The mesh models are divided using ICEM-CFD software. The numerical simulation of the liquid-gas two-phase flow is performed on the cavitation and noise of the flow field inside the cone valve based on FLUENT software. The visible experimental platform for cavitation and noise of hydraulic cone valve is built. According to the contrast of the experimental results, the correctness of the simulation results is verified.
Findings
The results show that the radial deviation causes the position of the cavitation accumulates in the valve cavity on the side of the upper cone. In addition, the strength of the cavitation changes slowly with the half cone angle of 45°, and the noise level is the smallest. Furthermore, appropriately increasing the opening degree within a reasonable range can effectively suppress cavitation and reduce the noise level.
Originality/value
The cavitation can be suppressed and the noise level can be reduced by means of changing the three factors, which lays the foundation for the design and theoretical research of the cone valve.

Abstract
Purpose
Internal leakage is one of the key factors that influence the super-low speed performance of continuous rotary electro-hydraulic servo motor. Therefore, this paper aims to study the change rule of internal leakage for improving the low speed performance of motor.
Design/methodology/approach
The mathematical models of internal leakage of continuous rotary electro-hydraulic servo motor were established, and according to the working principle of the motor, the 3D models of internal leakage location were established. Simulation analysis was implemented on the continuous rotary electro-hydraulic servo motor by the finite element analysis software ANSYS based on the fluid-structure interaction theory.
Findings
The results show the deformation of motor’s key parts and the changing rule of internal leakage. The effect of the leakage to the low speed performance of electro-hydraulic servo motor was analyzed, and at the same time, the motor’s leakage experiment was also conducted to verify the validity of simulation results.
Originality/value
This paper lays the foundation for improving the low speed performance of motor.

Abstract
This chapter aims to investigate and interpret China’s educational aid by analyzing its history, philosophies, and practices in Africa. The study is based on review and analysis of governmental documents, reports, academic papers, and news by Chinese and foreign scholars on China’s aid, particularly educational aid to Africa. The analysis unveils three transformations of China’s aid “from pro-ideology to de-ideology,” “from single area to multiple areas,” and “from pragmatic economy driven to sustainable and humane economy focused” in Africa. Meanwhile, it indicates a continuity of the philosophy of solidarity, morality, and reciprocity in China’s South-South cooperation with African educational development.
The analysis also shows China’s educational aid does not match well with the framework of the Western donors. China, under the FOCAC framework, is devoted to higher education cooperation, human resources training program, scholarship, and Chinese language education with African partners. With the growth of its economic and political influence, China will play multiple roles as the biggest developing country and as an active promoter and provider for South-South cooperation in the negotiation and construction of the post-2015 agenda. Nevertheless, we assume China will keep a pragmatic higher education cooperation with its developing country partners to inclusively link it with business, technology transfer, and people-to-people exchange.
This study delivers a comprehensive review and analysis of paradigm shift, philosophy, mechanism, and practice of China’s educational aid to Africa to fill up the literature gap in this field. It also timely presents China’s stance toward discussion on the post-2015 agenda.

Abstract
From the sixteenth to eighteenth century, China underwent a commercial revolution similar to the one in contemporaneous Europe. The rise of market did foster the rise of a nascent bourgeois and the concomitant rise of a liberal, populist version of Confucianism, which advocated a more decentralized and less authoritarian political system in the last few decades of the Ming dynasty (1368–1644). But after the collapse of the Ming Empire and the establishment of the Qing Empire (1644–1911) by the Manchu conquerors, the new rulers designated the late-Ming liberal ideologies as heretics, and they resurrected the most conservative form of Confucianism as the political orthodoxy. Under the principle of filial piety given by this orthodoxy, the whole empire was imagined as a fictitious family with the emperor as the grand patriarch and the civil bureaucrats and subjects as children or grandchildren. Under the highly centralized administrative and communicative apparatus of the Qing state, this ideology of the fictitious patrimonial state penetrated into the lowest level of the society. The subsequent paternalist, authoritarian, and moralizing politics of the Qing state contributed to China’s nontransition to capitalism despite its advanced market economy, and helped explain the peculiar form and trajectory of China’s popular contention in the eighteenth century. I also argue that this tradition of fictitious patrimonial politics continued to shape the state-making processes in twentieth-century China and beyond.

Abstract
Purpose
The core of the micro–macro paradigm of mainstream Western economics is the assumption that a rational economic man with complete freedom of economic behaviors living in a fully competitive, free-market economy pursues maximum personal benefits. The purpose of this paper is to show the reasons for failure of mainstream Western economics explaining the “mystery of China’s economic growth” and the necessity of understanding the mystery from the paradigm of realm economics.
Design/methodology/approach
The system of socialism with Chinese characteristics led by the Communist Party of China (CPC) and the local governments that play a crucial role in the reform and opening-up has the realm attribute. It is necessary to develop a new paradigm for realm economic analysis and promote the creation of new economic globalization and international political and economic order.
Findings
According to the fourth plenary session of the 19th CPC Central Committee, “Since the New China was founded 70 years ago, our Party has led our people to create the rarely-seen miracle of rapid economic development and miracle of long-term social stability”. The authors find that it is effective and necessary to explain the miracle of China’s economic growth from the paradigm of realm economics.
Originality/value
As proven by practice, the system of socialism with Chinese characteristics and the governance system of China are guided by Marxism, rooted in China with a deep Chinese cultural foundation, and sincerely supported by the people.

Abstract
This chapter reviews the status of Education For All (EFA) in China and identifies four gaps: between rural and urban residents, between residents of geographic regions, between ethnicity groups, and between the genders. It turns to examine the educational situation and interests of girls weighed down by the crushing burden of multiple disadvantages in “left-behind” Western China. Based on analysis of macro-level socio-economic and educational conditions, along with rich micro-level data on girls’ vigorous pursuit of education, the authors argue that the changing conditions of rural girls’ lives and their education can best be understood from a critical empowerment perspective. Summarizing the global discourse and cross national evidence on the benefits of girls’ education, the chapter and looks beyond a utilitarian perspective and argues for the cogency of a critical empowerment framework. Filled with telling stories and case studies of Han Chinese, Tibetan, and Muslim girls, this chapter proposes that prioritizing girls’ education in Western China is crucial and required for achieving the MDG of gender parity. Even though girls are often stranded by family financial conditions, their actions and ideas seeing education as their future reflect a changing gender identity and role in the family and society. The fieldwork suggests that educating girls promotes localized development, reduces dangerous levels of economic gaps and social instability, but also advances hard to measure effects: personal and civil empowerment, and sustainable, harmonious cultural change – as well as MDG.

Abstract
This chapter examines the changing state–university–student relationships in post/socialist China since the late 1980s. We begin with an introduction to four salient themes in scholarship on Chinese post/socialism that are highly relevant to higher education: globalization, gradualism, civic society, and a critique of holism. These themes help us explain interrelated educational trends that affect the state–university–student relationship: the globalization, “massification,” and stratification of higher education; the redefined role of the state in university governance and management; higher education marketization and privatization; and the quest for meaning and (e)quality in and through higher education. Our general argument is that during the “socialist” period the main relationship central to higher learning was between the state and students. Universities were agents of the state; from a legal point of view, indeed, universities did not have an independent status from the state. In the “post-socialist” era the university–student relationship has become more significant. We examine this reconfiguration through two case studies, one on the development of college student grievance and rights consciousness, and the other on reforms in higher education student services administration. When looked at from the point of view of the state, we see that appropriation and implementation of policies and regulations shaping student rights and services are in partial contradiction with state policies to accelerate economic growth and bolster party authority. From the point of view of universities, we see institutions grappling with how to deliver on forward-looking structures and actions while navigating between the state's policy mandates and growing expectations and demands of its student and business stakeholders. From the point of view of students, we see how constrained agency, uncertainty, and the power of the credential motivates social praxis. At all levels of the state–institution–student relationship actors are employing a kind of pragmatic improvisation (one of the salient features of post/socialism) captured by the well-known Chinese proverb “groping for stones to cross the river.” This saying is an apt metaphor for the tentative searching by state, institution, and individual for a safe foothold in the post/socialist world.

Abstract
Purpose
The modernization of China’s economy is an integral part of Chinese-style modernization. According to the principle of unifying theoretical, historical and practical logic, theoretically explaining the modernization of China’s economy is both a political necessity and a higher scientific requirement.
Design/methodology/approach
Following this evolutionary line – from modes of production to the general economic development mechanism and then to patterns of economic operation and development – this paper employs the principal contradiction analysis method to offer an interpretation of China’s economic modernization from the broad Marxist political economy perspective.
Findings
In economic terms, “get organized” primarily refers to the development and mutual promotion of team-based and market-based division of labor organizations, as discussed by Karl Marx. “Get organized” (specifically the development of team-based division of labor organizations) acts as the engine of China’s economic modernization and serves as the historical logical starting point. Division of labor is the theoretical logical starting point for interpreting China’s economic modernization. The two of them are congruent, achieving the unity of theoretical and historical logic at the starting point. The development and mutual promotion of these “two types of division of labor” inherently generate the general mechanism of economic development first comprehensively discussed by Marx and Friedrich Engels, which involves the division of labor development and market expansion accumulating cyclically and reinforcing each other. This mechanism drives both the high-speed and high-quality development of China’s economic modernization.
Originality/value
The broad Marxist political economy paradigm facilitates explaining China’s economic modernization theoretically, historically and practically with unified logic. “Get organized” serves as both the engine and the realization mechanism of this modernization, with the Communist Party of China (CPC) consistently being the core force of this organizational effort.

Abstract
Purpose
Francois Quesnay, known as the “Confucius of Europe”, was profoundly influenced by traditional Chinese culture to form his thoughts, which contained strong Chinese characteristics. This paper aims to examine economic thought of Francois Quesnay from the perspective of the construction of socialist political economics with Chinese characteristics.
Design/methodology/approach
Moreover, his thoughts also profoundly influenced subsequent economists, such as Adam Smith and Karl Marx. It can be said that Francois Quesnay was at the intersection of Chinese, Western and Marxist thought systems, so it is quite important to examine his thoughts critically and conduct source-tracing in China.
Findings
Hence, in the process of constructing and developing socialist political economy with Chinese characteristics, there is an urgent need to focus on exploring the value of excellent traditional Chinese culture at the theoretical level and combining the development and dissemination of the history of thoughts and the historical position of Chinese reality to realize the innovation and development of socialist political economy with Chinese characteristics.
Originality/value
Meanwhile, while absorbing nutrition from excellent traditional Chinese culture, it is necessary to establish scientific coordinates rather than use the discourse systems and paradigms of Western economics to interpret ancient Chinese economic thoughts. It is necessary to adhere to, inherit and develop Marxist political economy and absorb nutrition from Chinese excellent traditional culture to construct socialist political economy with Chinese characteristics.

Abstract
Purpose
Given the recent emergence of China as a dominant economy and internal changes that have led to the encouragement of entrepreneurship and entrepreneurial initiatives, this paper explores whether family dynamics and relationships still play an important role in women's decision to become entrepreneurs. It aims to understand whether there has been a shift in family dynamics and decision-making that supports female entrepreneurship.
Design/methodology/approach
Given that the purpose of the study is to understand the role of relationships and family dynamics in their career choice, this study has taken a qualitative approach and carried out interviews with fifteen Chinese female entrepreneurs to understand the role of relationships and family dynamics in their career choice.
Findings
The results note that though there are changes in family dynamics that encourage female entrepreneurship, women still find it difficult to choose entrepreneurship as a career and there are unfair expectations that are placed on them. The expectations create undue stress which directly affects their ability to carry out their professional duties. The research suggests that to foster the development of female entrepreneurship, government agencies and local government bodies should provide further access to family support services that can facilitate women's empowerment and foster entrepreneurial thinking without feeling guilty about family commitments or unfair expectations.
Originality/value
Recent studies on women's entrepreneurship have focused on various facets. The role of family dynamics and relationships has long been studied in the context of female entrepreneurship. In emerging economies like China, family dynamics and relationships determine whether women can choose entrepreneurship as a career choice or not. However, there is very limited research on the topic, in the geographical context of China. Hence, this paper is among pioneer research addressing family dynamics in the female entrepreneurship debate in China.
