This paper aims to develop a new magnetorheological polishing (MRP) device with roller and investigate the polishing mechanism of MRP fluids using this new device.

The principle of MRP process with roller is discussed, and then the structure of the polishing device is designed in detail. The polishing experiments of K9 glass are carried out using MRP device with roller.

A series of tests are performed to evaluate the effect of the excitation gaps, working gap and polishing time on the polishing characteristics, and the optimized polishing parameters can be obtained. The surface roughness Ra of the sample is reduced from 359 to 38 nm under optimized polishing parameters.

MRP method with roller is proposed in this paper, and the MRP device with roller can reduce the surface roughness Ra significantly. After being polished, the circular ring-shaped polishing belt disappears on the workpiece surface, which means it has great potential for polishing.

The purpose of this paper is to provide an understanding of principal preparation and training in China by providing a background discussion of principal preparation in a number of countries. As an illustration, it provides an overview of the curriculum used in the initial preparation of school principals at Beijing Normal University.

The paper draws mainly on writing and research from China, Australia and the USA to explore principal preparation and training in China.

In addition to providing a rich description of principal preparation in China, the paper's main findings comprise seven key challenges that confront China as it endeavours to provide quality principal preparation. These challenges include China's diversity and uneven social, cultural and educational development; limited resources in some regions throughout China; the place and importance of study tours for principal preparation; the teaching approach used to train principals; the process used for assessing principal learning during their training programs; the limited transfer of learning from the classroom to the school environment; and the timing of training for principals.

Each of the challenges arising here raises important practical implications for developers of principal training programs.

The paper paints a picture of principal preparation in China and raises a number of issues and challenges with which it continues to grapple. Of note is that China is not alone in facing some of these ongoing concerns.

The nickel-based alloys Inconel 625 and Inconel 718 stand out due to their high strength and corrosion resistance in important industries like aerospace, aviation and automotive. Even though they are widely used, current techniques of producing materials that are difficult to cut pose several problems from a financial, ecological and even health perspective. To handle these problems and acquire improved mechanical and structural qualities, laser powder bed fusion (LPBF) has been widely used as one of the most essential additive manufacturing techniques. The purpose of this article is to focus on the state of the art on LPBF parts of Inconel 625 and Inconel 718 for microstructure, mechanical behavior and postprocessing.

The mechanical behavior of LPBF-fabricated Inconel is described, including hardness, surface morphology and wear, as well as the influence of fabrication orientation on surface quality, biocompatibility and resultant mechanical properties, particularly tensile strength, fatigue performance and tribological behaviors.

The postprocessing techniques such as thermal treatments, polishing techniques for surface enhancement, mechanical and laser-induced peening and physical operations are summarized.

The highlighted topic presents the critical aspects of the advantages and challenges of the LPBF parts produced by Inconel 718 and 625, which can be a guideline for manufacturers and academia in practical applications.

The objective of this study is to model the propagating front in the interaction of gases in an aircraft fuel tank. To this end, we introduce a nonlinear parabolic operator, for which solutions are shown to be regular.

The authors provide an analytical expression for the propagating front, that shifts any combination of oxygen and nitrogen, in the tank airspace, into a safe condition to avoid potential explosions. The analytical exercise is validated with a real flight.

According to the flight test data, the safe condition, of maximum 7% of oxygen, is given for a time t = 45.2 min since the beginning of the flight, while according to our analysis, such a safe level is obtained for t = 41.42 min. For other safe levels of oxygen, the error between the analytical assessment and the flight data was observed to be below 10%.

The interaction of gases in a fuel tank has been little explored in the literature. Our value consists of introducing a set of nonlinear partial differential equations to increase the accuracy in modeling the interaction of gasses, which has been typically done via algebraic equations.

Smog seriously affects the ecological environment and poses a threat to public health. Therefore, smog control has become a key task in China, which requires reliable prediction.

This paper establishes a novel time-lag GM(1,N) model based on interval grey number sequences. Firstly, calculating kernel and degree of greyness of the interval grey number sequence respectively. Then, establishing the time-lag GM(1,N) model of kernel and degree of greyness sequences respectively to obtain their values after determining the time-lag parameters of two models. Finally, the upper and lower bounds of interval grey number sequences are obtained by restoring the values of kernel and degree of greyness.

In order to verify the validity and practicability of the model, the monthly concentrations of PM2.5, SO2 and NO2 in Beijing during August 2017 to September 2018 are selected to establish the time-lag GM(1,3) model for kernel and degree of greyness sequences respectively. Compared with three existing models, the proposed model in this paper has better simulation accuracy. Therefore, the novel model is applied to forecast monthly PM2.5 concentration for October to December 2018 in Beijing and provides a reference basis for the government to formulate smog control policies.

The proposed model can simulate and forecast system characteristic data with the time-lag effect more accurately, which shows that the time-lag GM(1,N) model proposed in this paper is practical and effective.

Based on interval grey number sequences, the traditional GM(1,N) model neglects the time-lag effect of driving terms, hence this paper introduces the time-lag parameters into driving terms of the traditional GM(1,N) model and proposes a novel time-lag GM(1,N) model.

This paper describes the parent–child relationships of upper-middle-class Chinese parents and their adolescent children who were “parachuted” to the United States for private high schools. With parents remaining in China and children in the United States, thousands of miles away, such a transnational educational arrangement complicates the already volatile parent–child relationships during the adolescent years. Through ethnographic interviews of 41 students and 33 parents, I demonstrate different forms of child–parent relationships in a transnational education setting: those who found that the further physical and temporal distance has brought the parent–child relationship closer through frequent communications, children who experienced “accelerated growth” yet questioned the necessity, and delicate parent–child relationships due to increasing transnational cross-cultural or intergenerational differences. These types of parent–child relationships are not comprehensive of all the lived experiences of the “parachute generation,” yet they shed new light on transnational education and the unintended emotional dimensions of educational migration. In a transnational context for an economically well-off group, parental absence or separation of children and parents is no longer a clear-cut concept and has different layers of meanings, taking into account the frequency of communication, duration of spring and winter breaks and the existence of third-party agents such as for-profit intermediaries (or educational consultants) and host families. The diverse patterns of parent–child relations reveal the heterogeneity and complexities of “doing family” across geographic spaces and global educational hierarchies, as well as the roles of communication technologies, the tempo of mobilities and educational intermediaries.

This study aims to analyze the existing body of knowledge concentrating on institutional investors’ behavior. It seeks to track how this domain has evolved through collaborative networks, as well as significant contributors, themes and research opportunities for future work.

The present study applies bibliometric analysis to examine the trends in the selected research field, using 446 articles from highly recognized journals indexed in the Scopus database.

The authors discovered that research on institutional investors’ behavior has significantly increased over the past four decades due to academic interest in the topic. This study observed five themes that unite the research in this field: institutional investors and corporate behavior; determinants of institutional investors’ trading patterns and performance; trading activity and its outcomes; herding, causes and consequences; and institutional investment and corporate performance. Moreover, future directions are penned down, such as how institutional investors’ control influences governance disclosures.

This study serves as a guide by mapping and analyzing the intellectual development of the research literature on institutional investors’ behavior. The authors contribute to the knowledge base by providing a solid foundation for further studies.

This study aims to provide a better understanding into how large-scale companies overcome their rigidity and bureaucracy, and transform entrepreneurial orientation (EO) into organizational responsiveness (e.g. interdepartmental collaboration [IDC]). It also clarifies the double-edged role of organizational culture in shaping IDC, specifically within the Chinese economy that is deeply influenced by Confucianism.

Datas were randomly collected from companies that reside in the Yangtze River Delta region. With a sample of 115 large-scale EO Chinese firms, consisting of 402 department managers and 115 executives. The study aggregates the scores to create an overall measurement for EO, collectivism, power distance and IDC in the analysis. Further, confirmatory factor analyses were used to measure the structural model fitness, and multiple regression analysis was used to assess the hypotheses.

The results show that in competitive environments, IDC, as a strategic response to EO and a risk aversion of inertia and bureaucracy, fully mediates the positive relationship between EO and organizational creativity. Furthermore, the positive association is more pronounced under high cultural collectivism or low power distance in large-scale firms.

This paper contributes to the understanding of EO approach at the organizational level. The results posit that when large companies adopt EO, they are proactive rather than passive and would exhibit IDC as an important strategic responsiveness. Moreover, different organizational cultural orientations (i.e. high collectivism and low power distance) help to build IDC before cultivating innovation.

The results in this study suggest that large companies should focus on developing IDC to overcome knowledge fragmentation, bureaucracy and inertia. Also, large firms should develop Human Resource Management practices, such as creating job rotation and workflow, as well as cultural trust and common beliefs. In contrast, they should be on guard against status differences and workplace hierarchy’s cultural context.

To the best of the authors’ knowledge, this is the first study that considers the roles of IDC and organizational culture and examines how large-scale entrepreneurial-oriented companies breed innovation.
