The purpose of this paper is to present some numerical methods based on different time stepping and space discretization methods for the Allen‐Cahn equation with non‐periodic boundary conditions.

In space the equation is discretized by the Chebyshev spectral method, while in time the exponential time differencing fourth‐order Runge‐Kutta (ETDRK4) and implicit‐explicit scheme are used. Also, for comparison the finite difference scheme in both space and time is used.

It is found that the use of implicit‐explicit scheme allows use of a large time‐step, since an explicit method has less order of accuracy as compared to implicit‐explicit method. In time‐stepping the proposed ETDRK4 does not behave well for this special kind of partial differential equation.

The paper presents some numerical methods based on different time stepping and space discretization methods for the Allen‐Cahn equation with non‐periodic boundary conditions.

This paper seeks to discuss the genealogical sources for Chinese immigrants as well as the settlement of Chinese in the USA and the historical evolution of Chinese names, their origins, arrangement and development. It aims to cover the origins of various classes of Chinese surnames, followed by the content description of a traditional genealogical book for jiapu.

The paper researches the various ways that a Chinese person can find out about their ancestry.

The paper reveals the roles of libraries, including serving the needs of patrons interested in genealogical research, preserving and interpreting information through oral and family history projects and collaborating with other libraries through interlibrary loan, document delivery, library consortia, collection management and international resource‐sharing.

The study provides information on where and how to locate the genealogical resources for researching the genealogy of a Chinese family.

The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

The goal is to explore the role of international education in a developing country's nation building in a mostly indigenous process.

This study reviews China's history of international education set in the larger context of different nation building tasks in the past two centuries.

The unique case of China with dramatic ups and downs in national fortunes in the past two hundred years serves to show that an open attitude to and an active engagement in international education are contributing factors for national prosperity. The case of China also serves to show that a self-determined agenda is of paramount importance in international education as a tool for nation building.

Few studies so far have paid attention to the specific relationship between the internationalization of higher education and nation building, so the topic of the paper is an important one and a necessary addition to the existing literature. What has been the role of international education in China's national transformation? What contributions has international education made to China's achievement of nation building goals at different stages of this transformation process? What implications can other developing nations draw from China's case with regard to the role of international education in nation building? These are the questions the researchers hope to answer in this study.

We introduce the concepts of information, uncertainty information, systems and uncertainty systems, analyze the intension of these concepts, and point out the differences and connections among various concepts of systems. We put forward a mathematical method to research uncertainty systems and present a problem that can be solved with our method but cannot be solved with the interval analyzing method. Otherwise, from analyzing the purpose of introducing the concepts of information, uncertainty information, systems and uncertainty systems, we conclude that uncertainty information and uncertainty systems are among the most important subjects studied in scientific research, especially in applied research, both that being presently conducted and the abundance which is to come in the future.

The purpose of this paper is to explore the fundamental content and structure of destructive leadership within the Chinese cultural context, through surveys of employees in Chinese organizations.

Methodologies such as documentary analysis, interview and survey were used in the study, and surveys were conducted on over 1,300 employees from Beijing, Shanghai and other cities in Guangdong and Zhejiang provinces. Then the content and structure of destructive leadership perceived by Chinese employees were examined using multiple statistical techniques including EFA (exploratory factor analysis) and CFA (confirmatory factor analysis).

The results of the survey showed that destructive leadership in Chinese organizations consists of four factors: corruption, excoriation of subordinates, abuse of subordinates and the loss of professional morality. The authors then compared the structure with relevant Western research findings and revealed their similarities and differences.

The structure of Chinese destructive leadership not only reflects the characteristics of Chinese culture, but also reflects the characteristics of current Chinese organizational management, which have practical implications for identifying management problems in Chinese organizations and improving workplace leadership behavior.

This is the first paper of its kind in mainland China to empirically explore the theoretical model of destructive leadership within the context of Chinese culture, which will facilitate future research by offering a theoretical basis and research instrument.

The metallic alloys and their components fabricated via laser powder bed fusion (LPBF) suffer from the microvoids formed inevitably due to the extreme solidification rate during fabrication, which are impossible to be removed by heat treatment. This paper aims to remove those microvoids in as-built AlSi10Mg alloys by hot forging and enhance their mechanical properties.

AlSi10Mg samples were built using prealloyed powder with a set of optimized LPBF parameters, viz. 350 W of laser power, 1,170 mm/s of scan speed, 50 µm of layer thickness and 0.24 mm of hatch spacing. As-built samples were preheated to 430°C followed by immediate pressing with two different thickness reductions of 10% and 35%. The effect of hot forging on the microstructure was analyzed by means of X-ray diffraction, scanning electron microscopy, electron backscattered diffraction and transmission electron microscopy. Tensile tests were performed to reveal the effect of hot forging on the mechanical properties.

By using hot forging, the large number of microvoids in both as-built and post heat-treated samples were mostly healed. Moreover, the Si particles were finer in forged condition (∼150 nm) compared with those in heat-treated condition (∼300 nm). Tensile tests showed that compared with heat treatment, the hot forging process could noticeably increase tensile strength at no expense of ductility. Consequently, the toughness (integration of tensile stress and strain) of forged alloy increased by ∼86% and ∼24% compared with as-built and heat-treated alloys, respectively.

Hot forging can effectively remove the inevitable microvoids in metals fabricated via LPBF, which is beneficial to the mechanical properties. These findings are inspiring for the evolution of the LPBF technique to eliminate the microvoids and boost the mechanical properties of metals fabricated via LPBF.

In light of university business English pedagogical innovation, this study reports an empirical study with 66 English major participants.

The study uses online survey and participant observation to investigate their practice-oriented motivation and needs, the perceptions of using vocational education and training pedagogy in business English teaching and the learning outcomes in a Chinese university context.

The study found participants with motivations to learn business and trade knowledge, develop practice-oriented abilities and the preferences of learning flexibly and autonomously. For the perceptions of using vocational education and training pedagogy, simulations of meetings and negotiations were recommended and the job-based competency development model was useful. Workplace simulation was also particularly suggested to bridge the gap between classroom and workplace. For learning outcomes, writing practices and workplace simulation were considered particularly useful. The learning gains were found in international trade correspondence writing. While the intention of continuing learning business English correspondence writing was identified, more opportunities should be created for more practice-oriented activities, such as internship or corporate visit.

Informed by vocational education and training theory, the study has important pedagogical, theoretical and policy implications for business English teaching in both China and worldwide contexts.
