The paper seeks to investigate the laser engineered net shaping (LENS) of metal thick‐wall parts from Ni‐based alloy powders.

The composition of Ni‐based alloy powders was determined from phase diagram, which was 84Ni14.4Cu1.6Sn. The powders were prepared by gas atomization. Deoxygenation and screen separation were applied to the powders to improve the sintering ability and narrow the particle size distribution before shaping. Thick‐wall metal parts were built by LENS under different conditions. The microstructures, surface morphologies of the prepared parts were characterized.

The gas atomized powders were almost uniformly spherical after sieving. Most of oxygen contained in the alloy powders could be removed in H₂ atmosphere for heating at 550°C for 2 h. These nickel‐based alloy powders with 150‐200 mesh size were suitable for powder feed system. And these powders were shaped successfully by LENS. Thick‐wall parts with thickness ranged from 20 to 25 mm were fabricated. The thickness of each layer was between 400 and 600 μm by scanning electron microscope. Metallographs revealed that dendritic structures with different characteristics were grown on XY‐, YZ‐ and XZ‐section.

The present experiments were limited by the atmosphere control during the LENS process. The oxide at the interface between two neighbor layers could decrease the mechanical properties if without good inert gas protection, such as a protective atmosphere chamber.

This paper describes a refined experimental program that is needed to resolve the remaining technical issues in LENS of thick‐wall parts. The nickel‐based alloy powders suitable for the LENS process were studied and prepared. After pretreatment, the self‐made powders have good shaping ability. Microstructure features were first discussed with the variation of the face orientation. The dendrite arm distance obtained by this experiment is between 8 and 20 μm, well conforming to the theory. The thick‐wall parts with dense structures were fabricated successfully to widen the field of application of LENS.

This study examined the dynamical and positive effects of leader consultation on employee proactivity from a motivational perspective.

Survey data were collected twice a day from 107 employees in a week by using an experience sampling method.

On a daily basis, leader consultation had a positive effect on employees’ state work engagement, which in turn promoted employees’ proactivity. Moreover, authoritarian leadership weakened the positive relationship between leader consultation and employees’ state work engagement.

The findings provided a new perspective regarding the potential dynamic motivational effect of leader consultation on employees and generated interesting implications for paradoxical leadership theory.

Computer programs were developed based on the finite element method and the charge simulation method for the calculation of three dimensional electric fields in high voltage engineering. A brief description of the applied methods with respect to the special requirements of high voltage engineering is presented. In order to use the specific advantages of the finite element method and the charge simulation method, two procedures combining both methods are proposed: an iterative method and a direct method. For the calculation of three dimensional problems without symmetry the iterative procedure has the advantage that the coupling program is small compared with the field calculation programs and no major changes in these programs are necessary.

The paper aims to investigate the clocking effect on a centrifugal pump with inlet guide vanes (IGVs).

The paper uses a computation fluid dynamics (CFD) framework to solve the unsteady flows in a centrifugal pump with inlet guide vanes. The relative position between the stationary vanes and the stationary volute tongue is defined as the clocking position when IGVs inside the suction pipe rotate along the circumferential direction.

The results show that clocking positions have little effect on the pump head and efficiency, however their influences are obvious for the pressure fluctuation and flow field in the centrifugal pump. The maximum difference of pressure amplitude at dominant frequency reach up to 28% on the monitoring point V8 at different clocking positions under design flow rate. For the large flow rate, the clocking effect on flow field and pressure fluctuation in centrifugal pump is similar to that of design flow rate. However, the clocking effect is nearly negligible at partial flow rate, because there are reverse flows around the tongue tip and obvious vortexes forming and developing in the impeller. Those complex phenomena interacting in the centrifugal pump make the clocking effect less evident.

The numerical investigation reveals the clocking effect on a centrifugal pump with inlet guide vanes, which also valuable for the stable operation and optimal design of centrifugal pumps.

The aim of this study was to examine the early stages of the COVID-19 outbreak and the international communication management of Chinese diplomats as a case for extending the definition of intermestic public diplomacy. The goal was to reveal how Beijing subtly used both domestic and foreign social media to organize a network for communication about COVID-19 and purposefully soften the highly centralized and hierarchical political propaganda of the Communist Party of China (CPC).

Based on the literature on digital public diplomacy, the authors applied the existing concept of intermestic to Chinese politics in order to demonstrate the digitalization of public diplomacy, along with its forms and strategies under an authoritarian regime. A hybrid methodology combining quantitative network analysis and qualitative discourse analysis permits examination of China's intermestic online communication network dynamics, shedding light on how such an intermestic practice promoted Chinese values and power to international publics in the early stages of the COVID-19 crisis.

The authors’ findings extend the implications of intermestic public diplomacy from a democratic context to an authoritarian one. By analyzing the content of public diplomacy and para-diplomatic social media accounts in China and abroad at the beginning of the COVID-19 crisis, the authors outlined China's early crisis management, explaining its intermestic public diplomacy transmission modes and strategies. Moreover, the authors identified changes in the narrative strategies of Chinese diplomats and journalists during this process.

The findings of this study underline that Beijing established a narrative-making virtual communication structure for disseminating favorable Chinese strategic narratives and voices through differentiated communication on domestic and foreign social media platforms. Such intermestic communication strategies were particularly evident and even further weaponized by Beijing in its large-scale Wolf Warrior diplomacy in the spring of 2020. Thus, the study’s findings help readers understand how China digitalized its public diplomacy, its digital communication patterns and strategies.

On the one hand, geopolitical uncertainty and the popularity of social media have contributed to the evolution of the intermestic model of public diplomacy. This model allows actors to coordinate homogenous and differentiated communication practices to deploy their influence. On the other hand, the authors did not examine how intermestic audiences perceive and receive public diplomacy practices. In future studies, scholars should measure the agenda-setting capacity of diplomatic actors by examining the effects of such intermestic communication efforts.

The relations between China and Singapore were once exampled as good bilateral relations in the region: stable and promising. Albeit gradually increasing competition, bilateral economic cooperation remains to be a stabilizer. However, the ambitious Belt and Road Initiative (BRI) and even more complicated Sino-US relations add up more uncertainties to bilateral relations. This paper aims to examine the fragility of bilateral relations against the overall backgrounds of the dynamic regional balance of power while analyzing the economic cooperation as the stabilizer and reviewing political mutual trust between China and Singapore.

This paper will apply historical and documentary review and qualitative analysis.

Led by its pragmatic foreign policy, Singapore hedges against China, even it seeks to deeply engaging China in all dimensions of bilateral ties, including economic, cultural and political. The grand strategy of the BRI signals the era of “keeping low profile”, leaving us far away. It will inevitably change the regional landscape geo-strategically. The USA clearly defines China as a strategic competitor, which represent Sino-US relations will not go back to the past. The traditional counterbalance strategy applied by Singapore works more difficultly when China intends to be stronger politically in the region. Economically and politically, there are no reasons for Singapore not to show positive support for the BRI. However, the BRI essentially provides a warning message that Singapore should explore a more practical and realistic strategy for not being constrained by China's geo-economic strategy. Singapore's picking side and its increasing military budget, China's assertiveness and the changing Sino-US relations imply the looming fragilities to bilateral relations.

The relations between China and Singapore were once exampled as good bilateral relations in the region: stable and promising. However, China and Singapore relations also ran into bumps from time to time over the years. We usually believe it is because of the peculiarity of Singapore's China policy. However, we should not neglect the dynamic regional balance of power and the changing Sino-US relations after the BRI was proposed. To fill this research gap, this paper will review the factors of stabilizers and the factors that bring fragility to bilateral relations between China and Singapore. The paper also argues that it is time for Beijing to make reflections on whether Beijing proposed BRI too early and whether Beijing over addressed on the magnificence and ambitions of the BRI.

The Chinese stock market is a typical emerging market with special features that are very different from those of mature markets. The objective of this study is to investigate whether and how these features affect the volatility‐volume relation for Chinese stocks.

This paper examines the roles of the number of trades, size of trades, and share volume in explaining the volatility‐volume relation in the Shanghai Stock Exchange with high frequency trade data used.

The results confirm that the volatility‐volume relation is driven mainly by the number of trades on the Chinese stock market. The number of trades explains the volatility‐volume relation better than the size of trades. Furthermore, some results are obtained that differ from those of mature markets, such as the US market. The results show that the second largest sized trades affect the volatility more than other trades on the Chinese market.

The results show that, in the Shanghai Stock Exchange, informed traders camouflage their private information or manipulation behavior through the second largest sized trades. The results may have important implications for work explaining the volatility‐volume relation on the Chinese stock market, further providing a reference by which to regulate emerging markets.

The purpose of this paper is to examine influence strategies in organization-stakeholder relationships, by examining the National Basketball Association (NBA) and Anschutz Entertainment Group’s (AEG) involvement in the operations of MasterCard Center in Beijing, China.

Using Frooman’s model of stakeholder influence strategies, a case study of AEG and the NBA China was undertaken, relying on archival sources and interviews with key stakeholders.

The study produced two major findings. First, Bloomage employed different influence strategies to press the NBA and AEG to further reduce their involvement in the MasterCard Center’s operations. Second, Bloomage used cultural differences to justify the need to reduce its reliance on the NBA and AEG.

The study adds to the literature on stakeholder theory and sport organizations by examining organizations establishing themselves in foreign markets, and the influence strategies employed by key local stakeholders.

This study explores the role of procedural and distributive justice in influencing supervisory trust, job satisfaction, and organizational commitment. Past work in U.S. settings has shown the differential effects of procedural and distributive justice on job attitudes while other work supports the relationship between both procedural and distributive justice with trust. This study attempts to replicate the US findings and extend them to samples from India, Germany, and China (Hong Kong). A theoretical model was tested via structural equation analysis. Organizational justice was found to be an important predictor of trust in all the samples, indicating the importance of these concepts in organizational life in different cultures. The implications of these results for future research are discussed.

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.

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.

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.

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.
