The purpose of this paper is to investigate the equivalent control authority of the conventional and circulation control (CC) wing of the aircraft and assess the energy expenditure and aerodynamic efficiency of the CC wing.

Four target cases with different flap deflection angles θ are set in advance for the conventional wing, and then a series of cases with different jet momentum coefficients Cμ are set for the CC wing. The lift, drag and momentum coefficient curves of the CC wing are compared to those of the four conventional wing cases. The curves with the best agreement are selected to establish the corresponding relation between θ and Cμ. The energy expenditure of the CC system is analyzed. The concept of equivalent lift-to-drag ratio for the CC wing is introduced to compare the aerodynamic efficiency with the conventional wing

The control authority of the conventional wing at θ = 0º, 10º, 20º, 30º are equivalent to the control authority of the CC wing with Cµ = 0.0, 0.005, 0.009 and 0.012. The CC system is more efficient at small Cµ than large Cµ.

This study could contribute to the application of the CC system on flapless aircrafts.

The corresponding relation between θ and Cµ is established by matching the equivalent control authority between the conventional wing and CC wing.

This chapter examines the development of accounting thought and practices in China with the purpose of illustrating its relevance to current accounting policies and practices. The review indicates that changes in accounting in China did not usually occur completely and easily. Over the past three decades, while Chinese accounting has gradually moved toward the Anglo-American model, convergence has presented unique features in China. For example, the review suggests that the accounting reforms in China have been heavily government-driven and that uniform accounting systems still remain. Chinese regulators maintain a cautious attitude toward the application of fair value and professional judgment, which are essentially the center of the Anglo-American accounting system. Furthermore, Chinese accounting regulators have a different view of business combinations from the IASB and have developed alternative accounting methods for those transactions. China’s departure from IFRS reflects its politico-economic context and essentially challenges the IASB’s goal of achieving international accounting convergence. China’s approach to internationally acceptable practices is likely to have implications for the effectiveness of the imported ideas.

The purpose of this paper is to study the yaw control of the flapless aircraft and investigate the equivalent control effect (ECE) and the power consumption of the pneumatic control.

The control effects of the mechanical control and the pneumatic control are calculated and the ECE curves are obtained. The power consumption of the pneumatic control is analyzed. A new pneumatic drag-type yaw control method is proposed. The mechanisms of the drag-type yaw control and the conventional thrust-type yaw control are explored. The drag-type yaw control is divided into two combined blowing forms: inner-top outer-bottom blowing and inner-bottom outer-top blowing. The differences between two kinds of the drag-type yaw control at a small angle of attack and a large angle of attack are explored.

The ECE curves of the pneumatic control are obtained. The power consumption of the drag-type yaw control is much lower than that of the thrust type. The lift coefficient of the inner-top outer-bottom blowing is higher than that of the inner-bottom outer-top blowing, but the inner-bottom outer-top blowing has higher efficiency of the yaw control at a large angle of attack.

This paper contributes to the research of the flapless aircraft.

A new pneumatic drag-type yaw control method of the flapless aircraft is proposed.

This study aims to analyse the impact of corporate social responsibility (CSR) on corporate innovation efficiency and the mechanism underlying this effect.

Data of non-financial listed companies operating in China from 2010 to 2019 were employed. Dual fixed-effects and dynamic panel models were used to explore the relationship between CSR and corporate innovation efficiency, and analyse its heterogeneity.

The researchers found that CSR reduces innovation efficiency in China. Further, (1) when enterprises conduct CSR to obtain excess returns, it is easy to form excess goodwill; (2) under the pressure of the government and society, enterprises passively assume CSR, thereby crowding out R&D funds; and (3) regardless of whether companies in the high-tech industry actively or passively assume social responsibilities, CSR will not have a significant impact on their innovation efficiency.

The sample of this research is limited to Chinese A-share listed companies and lacks consideration for small and medium-sized enterprises. Therefore, whether the conclusions of this article are applicable to small and medium-sized enterprises or family enterprises needs further verification.

The research explores the intrinsic motivation and possible consequences of CSR from the dual perspectives of corporate active and passive.

The ultimate goal of a firm is to make a profit. In practice, few enterprises pay without any return. Perhaps some companies actively assume social responsibilities in order to obtain greater benefits, while passively assume social responsibilities due to oppression.

This study analyses the impact of CSR on corporate innovation efficiency from both active and passive perspectives. The results have important implications for government officials and entrepreneurs.

This work concerns the electrodeposition of highly pure brushite (CaHPO₄·2H₂O) on titanium alloy substrates and the transformation of the brushite to hydroxyapatite (HAp) Ca₁₀(PO₄)₆(OH)₂ as a coating for orthopaedic implants. Thus, the electrodeposition of electrolyte containing calcium nitrate and ammonium hydrogen phosphate was carried out. The influences of the substrate surface treatment, the electroplating conditions (bath composition, current density, pH value and temperature) and the hydrothermal post treatment conditions on the deposition rate, the throwing power, the adhesion, the morphology and the structure of the coating were evaluated. High adhesion bond strength (around 23 mPa) was achieved on a rough clean substrate, which is slightly higher than plasma sprayed HAp coating on titanium alloy.

In any time and space and under any circumstance, we find peasants are never passive actors in their livelihoods and rural development. Instead, they always create space for manoeuvre in order to make changes. This chapter analyses the innovative actions taken by the majority of rural inhabitants in rural areas during the overwhelming modernization process, so as to affirm that peasants are the main actors of rural development. It is they who have shaped the transformation of rural societies and the history. Through the analysis, this chapter concludes that rural development is not an objective, a blueprint nor a design. It is not the to-be-developed rear field in modernization. It is not the babysitter for cities, nor a rehearsal place for bureaucrats to testify their random thoughts. Rural development is what peasants do. The path they have chosen reveals scenery so different from modernization. If we regard development as a social change, or a cross with influential meanings, we could understand rural development as peasants’ victories over their predicament. Villages accommodate not only peasants, but without peasants villages would surely vanish. In this sense, the most important part in rural development or rural change is peasants – their conditions and their feelings.

The debate over differences in the behaviors of firms facing globalization is ongoing. This study examines whether globalization impacts the behavior of family firms and if this influence differs between family and non-family firms.

Drawing on panel data from the Amadeus database on 62 family firms and 98 non-family firms in Europe, the authors employ panel vector autoregression estimation and the Wald test of Granger causality to verify our conjecture. Additional impulse response functions and the forecast error variance decomposition technique were applied to illustrate complementary shock dynamics. Additionally, the KOF globalization index is used as a proxy for globalization.

The results show that globalization visibly impacts family and non-family firms, but the polarity and extent of the effect are different. The authors demonstrate that family firms are in a more favorable position regarding globalization and are less vulnerable to the adverse effects of the globalization process. In contrast, non-family firms fare worse, generating adverse effects. Non-family firms take a more open stance toward globalization than family firms' more conservative behaviors.

Of course, there are some limitations to the work presented in this paper. On the one hand, the authors’ data span only ten years due to data limitations. This causes the generalizability of the results to be hindered. Therefore, the authors encourage scholars to collect more time series data to increase confidence in the empirical results in future studies. On the other hand, the selection of proxy indicators concerning family firm behavior is mainly focused on financial and employment facets. A multidimensional selection of indicators could make the findings of this study more convincing. Despite its limitations, the study certainly adds to the authors’ understanding of its behavior and globalization activities.

The authors’ findings have twofold theoretical and practical implications, as they highlight the necessity of developing specific policies aimed at reducing the gap between family and non-family facing globalization and promoting sustainable operations of non-family firms. Although family firms tend to be more frugal and conservative in their overall decision-making, it should be acknowledged that stockholder and stakeholder interest-oriented corporate management policies have made them more capable of steadily improving corporate performance in the sweep of globalization.

To this end, this study deepens the authors’ understanding of the theory of global governance of family firms. It also provides possible paths and directions for future theoretical research on family firms. Globalization affects both family and non-family firms, but our results suggest that family firms are better able to withstand the adverse effects of globalization shocks and adopt efficient governance paths and strategic thinking to gain a competitive advantage. In this regard, the authors encourage non-family firms to actively learn from family firms' operational practices and systems to achieve better adaptability.

This study provides strong empirical evidence on the effectiveness of family firms' governance patterns and business behavior under globalization. Additionally, this study also reveals that managers can learn from the practical experience of family firms to help them confront business crises and gain a sustainable competitive advantage.

This study incorporates two Chinese cultural variables guanxi (personal relationship) and xinyong (personal trust) with other relational variables that are well defined in the west, i.e. supplier competence, commitment, conflict handling and satisfaction to see how they generate partnership relationship in a sino‐western relationship marketing context.

Research objectives are achieved through a combination of model building, quantitative design, testing of hypotheses using AMOS and analysis of findings. The subject scope is imbedded within cultural impact on relationship marketing in a sino‐western context.

This study finds that Western suppliers must be competent in product knowledge, market development, and adaptation to buyers' requirements to resolve conflicts in order to establish their xinyong with the buyers. Competence allows suppliers to show psychological commitment and establish guanxi with the buyers. It also shows that guanxi has a stronger influence on xinyong than on satisfaction. Suppliers should use guanxi to generate buyer's perception on xinyong whilst maintaining a reasonable level of buyer satisfaction with their products and services. Also, relationship between xinyong and satisfaction is not significant. A buyer's satisfaction on the supplier's product and services does not necessarily mean that this buyer perceives the supplier having xinyong because Chinese mix (up) business with personal relationships together and sometimes they make trade‐off between them!

This relationship study was conducted in a single‐product relationship context within the clothing industry in the PRC environment and therefore, its findings may not be generalised to other industry. Future Chinese relationship study should increase the sample size so as to cover more industries to allow comparison across industries. This is especially valid between a manufacturing and a service‐based industry. A service‐based industry may even emphasize more on guanxi and xinyong because of its intangible aspects! Future research should include the xinyong constructs, the concepts of face and reciprocity. To what extent these important Chinese cultural values affect satisfaction and xinyong have not been determined.

Effective conflict handling skills and guanxi are vital to formulate a xinyong positioning strategy. A supplier must be competent in product knowledge, market development skills, and adapt to a buyer's requirements to resolve conflicts with the buyer to establish xinyong.

This research is an initial attempt to establish the relationship between guanxi, xinyong and partnership relationship and generates a new research area in Chinese relationship marketing.

To simulate the dynamic feature of bulk granular material (such as agricultural products) during sudden braking of a truck by applying discrete element method.

The bulk granular material was modeled by the discrete element approach, in which the spherical elements were used to represent the granular particles; the interaction between two in‐adhesive particles was modeled by Hertz for normal interaction, and by Mindlin and Deresiewicz for tangential interaction; the interaction between two particles with adhesion was modeled by the JKR theory for normal interaction, and by Thornton's theory for the tangential interaction. Different initial conditions (braking speeds/accelerations) were considered. The dynamic system was numerically solved by the central difference based explicit time integration, and the dynamic impact forces were recorded to further analysis.

The computation predicted that the resultant dynamic force acting upon the front wall behaves in four stages, i.e. increasing, plateau, sharp increasing and drop with damped fluctuation. It was observed that, the shorter the breaking time is, the faster the force reaches its peak, and the greater the peak value is. The phenomenon was in good agreement with physical principals and common knowledge.

It is an application of the discrete element method and, therefore, no important contribution is made to advance the methodology.

The proposed modeling approach may serve as a useful tool for advanced design of trucks.

This paper is the first to apply the advanced discrete element method to the problem concerned.

The purpose of this paper is to investigate and improve a new method of unstructured rotational dynamic overset grids, which can be used to simulate the unsteady flows around rotational parts of aircraft.

The computational domain is decomposed into two sub-domains, namely, the rotational sub-domain which contains the rotational boundaries, and the stationary sub-domain which contains the remainder flow field including the stationary boundaries. The artificial boundaries and restriction boundaries are used as the restriction condition to generate the entire computational grid, and then the overset grids are established according to the radius parameters of artificial boundaries set previously. The deformation of rotational boundary is treated by using the linear spring analogy method which is suitable for the dynamic unstructured grid. The unsteady Navier-Stokes/Euler equations are solved separately in the rotational sub-domain and stationary sub-domain, and data coupling is accomplished through the overlapping area. The least squares method is used to interpolate the flow variables for the artificial boundary points with a higher calculating precision. Implicit lower-upper symmetric-Gauss-Seidel (LU-SGS) time stepping scheme is implemented to accelerate the inner iteration during the unsteady simulation.

The airfoil steady flow, airfoil pitching unsteady flow, three-dimensional (3-D) rotor flow field, rotor-fuselage interaction unsteady flow field and the flutter exciting system unsteady flow field are numerically simulated, and the results have good agreements with the experimental data. It is shown that the present method is valid and efficient for the prediction of complicated unsteady problems which contain rotational dynamic boundaries.

The results are entirely based on computational fluid dynamics (CFD), and the 3D simulations are based on the Euler equations in which the viscous effect is ignored. The current work shows further applicable potential to simulate unsteady flow around rotational parts of aircraft.

The current study can be used to simulate the two-dimensional airfoil pitching, 3-D rotor flow field, rotor-fuselage interaction and the flutter exciting system unsteady flow. The work will help the aircraft designer to get the unsteady flow character around rotational parts of aircraft.

A new type of rotational dynamic overset grids is presented and validated, and the current work has a significant contribution to the development of unstructured rotational dynamic overset grids.
