The purpose of this paper is to propose an alternative perspective on Zhong-Yong that is different from the notion of “Yin-Yang balancing” and apply it to understand the issue of balancing the top-down and bottom-up processes in strategy making.

The authors adopt a “West meets East” mindset and approach to develop an alternative perspective on Zhong-Yong, and then apply this perspective to understand the issue of balancing the top-down and bottom-up processes in strategy making. There are three steps in the process of developing the alternative perspective. First, the authors argue that the essence of “Yin-Yang balancing” is a ratio-based solution to paradoxical balancing, which is in fact equivalent to Aristotle’s doctrine of the mean and compatible with some western management scholars’ approaches to solving paradox. Second, the authors identify a different generic solution to paradoxical balancing implicit in the western management literature. Third, the authors find in the original text of Zhong-Yong equivalent ideas to the identified different generic solution and then propose an alternative perspective on Zhong-Yong that is fundamentally different from the notion of “Yin-Yang balancing.”

Applied to the issue of balancing the top-down and bottom-up processes in strategy making, the new perspective on Zhong-Yong provides us with the following prescriptive insights from the life-wisdom of eastern philosophy: first, top management (e.g. Shun as the sage-king) must listen to various views and opinions also from employees and low-level managers at the bottom of the organization to be better informed about complex issues. Second, top management must analyze the diverse elements of the various views and opinions they collect and synthesize by taking the good from the bad to find smarter solutions and make decisions with better outcomes. Third, abiding by a set of (more or less) cohesive values help top managers be open and receptive to information and insights from low-level organizational members and enhancing unbiased information.

This paper is mainly a theoretical perspective. Empirical work is needed to test the prescriptions offered in this paper.

Practitioners may learn new perspectives from ancient Chinese philosophies on how to balance.

This paper applies a new perspective on Zhong-Yong to an important paradox in strategic management.

In the face of external paradoxical requirements, the cognitive framework of managers and employees use to perceive, interpret and reconstruct information is important to ease anxiety and improve job performance. The Yin-Yang balancing of eastern philosophical thought is particularly good at explaining and predicting changes and conflict environments. For this reason, this study aims to propose the eastern construction of the paradoxical cognitive framework based on the Yin-Yang balancing theory and its antecedent framework.

This paper contrasts the similarity and differences between Chinese and Western philosophy’s thoughts on paradoxes. On this basis, the eastern construction of the paradoxical cognitive framework is proposed. Then, the paper puts forward the antecedent framework of managers’ cognitive framework and employees’ paradoxical cognitive framework.

This paper proposes the eastern construction of the paradoxical cognitive framework includes the following three dimensions: the unity-in-diversity of paradoxical elements, the asymmetric balance of paradoxical elements and mutual transformation of paradoxical elements. In addition, this paper proposes an antecedent framework of the eastern construction of the paradoxical cognitive framework – the paradoxical requirement of organizational environment exerts a direct impact on managers’ and employees’ paradoxical cognitive framework; managers’ paradoxical cognitive framework has a positive impact on paradoxical leadership; paradoxical leadership exerts an indirect impact on employees’ paradoxical cognitive framework through the collective paradoxical cognitive framework; paradoxical leadership directly affects employees’ paradoxical cognitive framework.

This paper focuses on comparing the similarities and differences of the individual paradoxical cognitive framework in Chinese and Western cultures and proposes the eastern construction of the paradoxical cognitive framework and its antecedent framework. Future research needs to further verify the theoretical framework proposed in this paper.

This paper makes a detailed comparison of the paradox views in Chinese and Western philosophy. It is the first to propose the eastern construction of the paradoxical cognitive framework and its antecedent framework, laying a theoretical foundation for future empirical research.

This paper aims to link location choice and ownership structure to the debate on the multinationality–performance relationship.

This paper draws on a panel data set that covers 1,321 emerging economy multinational enterprises (EMNEs) and includes 4,227 observations from 44 emerging economies between 2004 and, 2013.

The empirical results find that multinationality has a positive effect on EMNEs’ performance, and that this positive effect is larger for their investments in developed countries than in developing countries. The study also finds that this positive effect of foreign operation in developed countries switch to negative at higher levels of multinationality for privately owned EMNEs than for state-owned EMNEs.

This paper provides new empirical evidence to support an institutional perspective of the internationalisation of EMNEs that are investing in developed countries, contributing to the multinationality-performance literature, highlighting the importance of foreign direct investment location decision and ownership structure.

This paper aims to retrospectively quantify the contribution of renewable energy consumption (REC) to mitigate the carbon dioxide (CO₂) emissions for the belt and road initiative (BRI) region. The reason is that, so far, still few scientists have deeply analyzed this underlying impact, especially from the income levels’ perspective.

The study divides the BRI region into four groups by the income levels (high, HI; upper middle, UM; lower middle, LM; lower, LO) during 1992–2014 and uses the logarithmic mean Divisia index.

The results show the REC of the BRI has an overall decreasing trend but the driving contribution to the CO₂ growth except that the HI group’s REC has an obviously mitigating contribution of −2.09%. The number indicates that it is necessary and urgent to exploit and use renewable energy, especially in mid- and low-income countries due to the large potential of carbon mitigation. Besides, during 2010–2014, the energy intensity effects of different groups were negative except for the low income group (positive, 5.47 million tonnes), which showed that some poor countries recently reduced CO₂ emissions only by extensively using renewable energy but not enhancing the corresponding efficiency. Conversely, in other rich countries, people paid more attention to improve the energy-use efficiency to lower energy intensity.

This study creatively analyzes this underlying impact of the REC to mitigate the CO₂ emissions from the income levels’ perspective and proposes some reasonable countermeasures of reducing CO₂ for the BRI region.

The purpose of this study is to investigate the tribological performance of helical gear pairs with consideration of the properties of non-Newtonian lubricant and the real three-dimensional (3D) topography of tooth flanks.

Based on the mixed elastohydrodynamic lubrication (EHL) theory for infinite line contact, this paper proposes a complete model for involute helical gear pairs considering the real 3D topography of tooth flanks and the properties of non-Newtonian lubricant. Film thickness, contact load and contact area ratios at the mid-point of contact line are studied for each angular displacement of pinion. Both the total friction coefficient and surface flash temperature are calculated after obtaining the values of pressure and subsurface stress. Then, the influences of input parameters including rotational speed and power are investigated.

During the meshing process, contact load ratio and area ratio of the two rough surface cases first increase and then decrease; the maximum flash temperature rise (MFTR) on the gear is lower than that on the pinion first, but later the situation converses. For cylindrical gears, on the plane of action, there is a point or a line where the instantaneous friction reduces to a minimum value in a sudden, as the sliding–rolling ratio becomes zero. When rotational speed increases, film thickness becomes larger, and meanwhile, contact load ratio, coefficient of friction and MFTR gradually reduce.

A comprehensive analysis is conducted and a computer program is developed for meshing geometry, kinematics, tooth contact, mixed EHL characteristics, friction, FTR and subsurface stress of involute helical gear pairs. Besides, a numerical simulation model is developed, which can be used to analyze mixed lubrication with 3D machined roughness under a wide range of operating conditions.

Graphene is a two-dimensional material. Its use has many advantages in gas sensing, but its long desorption process is problematic. The aim of this paper is to design a graphene-based gas sensor, study the response to NO₂ gas concentrations and find ways to accelerate the desorption process.

In one group, the sensor was placed in air to measure its initial resistance. Then, it was exposed to the NO₂ gas at a certain concentration. Finally, the sensor was exposed to light immediately after NO₂ gas exposure was ended. In another group, the sensor was heated using a heating plate at a stable temperature, before taking the measurements. Then the adsorption and desorption experiments were carried on.

Illumination and heating at a suitable temperature can expedite desorption of NO₂ molecules on graphene.

In the paper, two main methods are introduced to accelerate the desorption process when the NO₂ gas is absorbed on graphene. Through a series of experiments and analysis, the authors found that the recovery time could be reduced observably and the recovery performance of the graphene-based NO₂ sensor could be improved effectively.

This study aims to improve the control accuracy and antidisturbance performance of the manipulator with the flexible link, a combined controller, which combines the novel backstepping sliding mode controller based on the extended state observer (ESO) and super-twisting sliding mode controller.

First, the dynamic of the system is constructed by Lagrange method and assumed mode method, and then the dynamic is decoupled by the singular perturbation theory to obtain the slow-varying subsystem and fast-varying subsystem. For the slow-varying subsystem, the novel backstepping sliding mode controller based on ESO is used to achieve joint tracking. For the fast-varying subsystem, the super-twisting sliding mode controller is used for vibration suppression. At the same time, to suppress chattering, the tanh function is used to replace the sign function in the reaching law.

The simulation results show that the combined control has better trajectory tracking performance, antiinterference performance and vibration suppression performance than traditional sliding mode control (SMC).

A novel backstepping sliding mode controller based on ESO is designed to guarantee the performance of the tracking trajectory. The new controller improves the converge rate. A super-twisting sliding mode controller, which can stabilize the fast-varying subsystem, is used to suppress the vibration of flexible link.

The purpose of this paper is to study the effect of J₃ perturbation of the Earth’s oblateness on satellite orbit compared with J₂ perturbation.

Based on the parametric variation method in the time domain, considering more accurate Earth potential function by considering J₃-perturbation effect, the perturbation equations about satellite’s six orbital elements (including semi-major axis, orbit inclination, right ascension of the ascending node, true anomaly, eccentricity and argument of perigee) has been deduced theoretically. The disturbance effects of J₂ and J₃ perturbations on the satellite orbit with different orbit inclinations have been studied numerically.

With the inclination increasing, the maximum of the semi-major axis increases weakly. The difference of inclination disturbed by the J₂ and J₃ perturbation is relative to orbit inclinations. J₃ perturbation has weak effect on the right ascension and argument of perigee. The critical angle of the right ascension and argument of perigee which decides the precession direction is 90° and 63.43°, respectively. The disturbance effects of J₂ and J₃ perturbations on the argument of perigee, right ascension and eccentricity are weakened when the eccentricity increases, simultaneously, the difference of J₂ and J₃ perturbations on argument of perigee, right ascension and argument of perigee decreases with eccentricity increasing, respectively.

In the future, satellites need to orbit the Earth much more precisely for a long period. The J₃ perturbation effect and the weight compared to J₂ perturbation in LEO can provide a theoretical reference for researchers who want to improve the control accuracy of satellite. On the other hand, the theoretical analysis and simulation results can help people to design the satellite orbit to avoid or diminish the disturbance effect of the Earth’s oblateness.

The J₃ perturbation equations of satellite orbit elements are deduced theoretically by using parametric variation method in this paper. Additionally, the comparison studies of J₂ perturbation and J₃ perturbation of the Earth’s oblateness on the satellite orbit with different initial conditions are presented.

Rapid prototyping (RP) technology is widely used in many fields in recent years. Bone tissue engineering (TE) is an interdisciplinary field involving life sciences, engineering and materials science. Hydroxyapatite (HAp) are similar to natural bone and it has been extensively studied due to its excellent biocompatibility and osteoconductivity. This paper aims to review nanoscaled HAp-based scaffolds with high porosity fabricated by various RP methods for bone regeneration.

The review focused on the fabrication methods of HAp composite scaffolds through RP techniques. The paper summarized the evaluation of these scaffolds on the basis of their biocompatibility and biodegradability through in vitro and in vivo tests. Finally, a summary and perspectives on this active area of research are provided.

HAp composite scaffold fabricated by RP methods has been widely used in bone TE and it has been deeply studied by researchers during the past two decades. However, its brittleness and difficulty in processing have largely limited its wide application in TE. Therefore, the formability of HAp combined with biocompatible organic materials and fabrication techniques could be effectively enhanced, and it can be used in bone TE applications finally.

This review paper presented a comprehensive study of the various types of HAp composite scaffold fabricated by RP technologies and introduced their potential application in bone TE, as well as future roadmap and perspective.

Deep excavation in soft clay often causes additional deformations to surroundings. Then, if deformations cannot be predicted reasonably, the adjacent buildings may be threatened by the deep excavation. Based on the good field observations from ten deep excavations in Hangzhou, this paper aims to thoroughly investigate the characteristics of wall deflections and ground settlements induced by deep excavations.

On the basis of good field observation of ten deep excavations, the performances of excavations, supported by contiguous pile in Hangzhou, were studied, and also compared with other case histories.

The maximum wall deflections (dhm) rang mostly from 0.7 to 1.2 per cent H_e, where He is the final excavation depth, larger than those in Taipei and Shanghai. The observed maximum ground settlement in the Hangzhou cases generally ranges from 0.2 to 0.8 per cent H_e. Then, the settlement influence zone extends to a distance of 2.0-4.0 H_e from the excavation. The relatively large movements and influence zones in Hangzhou may be attributed to low stability numbers, large excavation widths and the creep effect. The excavation width is justified to have a significant influence on the wall deflection. Therefore, to establish a semi-empirical formula for predicting the maximum wall deflection, it is necessary to include the factor of excavation width.

The relevant literature concentrated on the characteristics of deep excavations supported by the contiguous pile wall in Hangzhou soft clay can rarely be found. Based on the ten deep excavations with good field observation in Hangzhou, the characteristics of wall deflection and ground settlements were comprehensively studied for the first time, which can provide some theoretical support for similar projects.
