Abstract
Purpose
This paper aims to propose and verify an improved cascade active disturbance rejection control (ADRC) scheme based on output redefinition for hypersonic vehicles (HSVs) with nonminimum phase characteristic and model uncertainties.
Design/methodology/approach
To handle the nonminimum phase characteristic, a tuning factor stabilizing internal dynamics is introduced to redefine the system output states; its effective range is determined by analyzing Byrnes–Isidori normalized form of the redefined system. The extended state observers (ESOs) are used to estimate the uncertainties, which include matched and mismatched items in the system. The controller compensates observations in real time and appends integral terms to improve robustness against the estimation errors of ESOs.
Findings
Theoretical and simulation results show that the stability of internal dynamics is guaranteed by the tuning factor and the tracking errors of external commands are globally asymptotically stable.
Practical implications
The control scheme in this paper is expected to generate a reliable way for dealing with nonminimum phase characteristic and model uncertainties of HSVs.
Originality/value
In the framework of ADRC, a concise form of redefined outputs is proposed, in which the tuning factor performs a decisive role in stabilizing the internal dynamics of HSVs. By introducing an integral term into the cascade ADRC scheme, the compensation accuracy of matched and mismatched disturbances is improved.

Abstract
Purpose
This study aims to build an indigenous Chinese management model based on Chinese culture.
Design/methodology/approach
This study adopts new institutionalism as its theoretical foundation, examines the core values of Chinese civilization in retrospect and identifies the key features of a Chinese management model. In this study, the authors develop a “glacier model” and test its reliability with the Haier Group.
Findings
This study proposes a new definition for a management model: a knowledge system based on institutional civilization that reflects management theory and practice. It analyzes the institutional environment of Chinese civilization: the recessive bottom-most layers are CBTLG (Confucianism, Taoism, Buddhism, legalism and Guan theory) and MDSX (Mao Zedong thought, Deng Xiaoping theory, scientific thoughts of development and Xi Jinping thought), the dominant principles are “Socialism and Mixed Economy” and the core values of Chinese culture compose the layer between them. This study concludes that the distinguishing features of Chinese management are harmonious management, the order-diversity pattern and Tai Chi management.
Research limitations/implications
This paper only discussed the management model of China. Based on the conclusions of this paper, in the future, researchers comparative studies on Chinese management and other countries’ management models with glacier model. By so doing, people can have a more comprehensive understanding of management models of different cultures.
Practical implications
The management characteristics contained in Chinese culture can provide more abundant knowledge for understanding current organizational management issues. A better understanding of the characteristics of a Chinese management model based on Chinese civilization is conducive to foreign investment or cross-cultural cooperation between Chinese and foreign enterprises.
Originality/value
This study provides a new perspective in studying Chinese management. The theoretical values of the glacier model are as follows: it is rooted in a Chinese management context; it makes up for the insufficiency in the current study of institutionalism; and it guides cross-cultural communication and management. The authors hope that the study attracts the attention of more scholars. Any civilization of any region or country can construct its own management model using the frame of the glacier model.

Abstract
Purpose
Innovation and entrepreneurship are regarded as the key drivers to steer the engine of economic development in any nation. As a result, to understand the context and process of innovation and entrepreneurship there has been a steady rise in scientific literature and empirical studies. The purpose of this paper is to study the trends and progress of academic research on innovation and entrepreneurship in India by identifying the key articles, journals, authors and institutions.
Design/methodology/approach
Scientometric methods especially bibliometrics is used, for measuring the maturity of this research field in the country. The paper studies the research landscape in innovation and entrepreneurship in India by doing a bibliometric analysis using data from publications indexed in the Scopus database from the year 2000 to 2018. The study takes a multidisciplinary review of the literature in innovation and entrepreneurship research in India and could be used as a reference for future studies in this theme.
Findings
The study finds an increase in the scholarly studies in innovation and entrepreneurship in India in the last decade. It was also found that a large number of publications were joint-authored and collaborations between Indian and foreign universities is happening. The paper also highlights the authorship patterns, top journals and the most cited papers.
Research limitations/implications
A major limitation of this study is that it has considered publications which are indexed in Scopus. This paper has contributed by highlighting the growth of studies in the field of innovation and entrepreneurship in the Indian context. The results can be used by future studies in this area as a starting point to highlight the nature of this research area.
Originality/value
The study attempts to present a trend analysis of published literature on innovation and entrepreneurship in India.

Abstract
Purpose
This study aims to explore the relationship between folk religious place-making and the development of urban public spaces and summarize its influence on community network construction and daily behavior to discover the authentic practices and role of folk faith culture in social space.
Design/methodology/approach
Taking Macau's Shi Gandang Temple and its belief culture as an example, on-site research, historical evidence and interviews were used to elaborate and analyze the processes of place-making, social functions, management mechanisms and folk culture to establish a new perception of folk religious place-making in contemporary urban spaces.
Findings
The article argues that the culture of folk beliefs profoundly influences urban spaces and the social management system of Macau and has a positive significance in building the local community and geopolitical relations. In addition, it suggests that the participation of folk religious places in local practices is important as key nodes and emotional hubs of local networks, reconciling conflicts between communities of different backgrounds and driving urban spaces toward diversity while forming a positive interaction and friendly cooperation between regional development and self-contained management mechanisms, governance models and cultural orientations.
Originality/value
This study takes an architectural and anthropological perspective of the impact of faith on urban spaces and local governance, using the Shi Gandang Temple in Macau as an example, to complement related studies.

Abstract
Purpose
The purpose of this paper is to test the assertion that the relationship between corporation performance and organizational complexity follows an inverted U-shape curve, and a corporation gains the best performance when its organizational complexity fits its environmental complexity.
Design/methodology/approach
This research did not directly measure environmental complexity to verify the relationship between corporation performance and complex environment, but measured organizational complexity to subtly display the effect of the organizational complexity on the corporation performance while controlled the environmental complexity. To do so, a set of corporations that shared the similar environment was selected, and then these corporations’ performance and organizational complexity were calculated, the related hypotheses were tested empirically.
Findings
The paper proved the inverted U-shape relationship between organizational complexity and corporation performance, and also found that different corporation chooses different complex adaptive way, so the inverted U-shape relationship displays hierarchy.
Research limitations/implications
Future research should search out to calculate corporation’s environment complexity the fitness of organizational complexity for testing hypotheses.
Practical implications
The regularity of relationship between organizational complexity and corporation performance is helpful for managers to understand that a way to improve a corporation’s performance is to enhance the fitness of organizational complexity and environmental complexity.
Social implications
Organizational complexity may be competitive advantage, but excessive growth of it will be harmful.
Originality/value
Usually organizational complexity is thought of as a negative factor to corporation performance and tends to be constrained, but this research explored the role of organizational complexity to corporation performance and the findings helps managers to understand when to enhance organizational complexity and when to weaken it. The methodology of calculating the fitness of organizational complexity and environmental complexity by fixing environment is a contribution to complexity theory research.

Abstract
Textbook content and curricula are artifacts that can serve as indicators of social contexts and societal values. In this chapter, we use qualitative and quantitative content analysis to examine the content of Chinese language arts textbooks for basic education during a period of curriculum reform in China at the start of the 21st century. Given the important role of the Chinese language arts in the socialization of students into official societal values, this study seeks to provide insight into the nature of the official world view in China and addresses the societal ambivalence between global vs. national/local and traditional knowledge vs. Western/contemporary knowledge. We find that there is a slight increase in themes that reflect contemporary global concerns such as creativity and social justice. We also find that, in the face of the globalizing cultural influences of the new millennium, there is a sustained emphasis on the role of the Chinese language curriculum in the transmission of traditional Chinese cultural values and on the cultivation in Chinese students of an appreciation of their rich cultural traditions.
