This study aims to further the understanding of support structures and the likely impacts on maraging steel MS1 parts fabricated by selective laser melting (SLM) at 45°, 60° and 75° building angles.

Two groups of samples, one group with support structures and the other group without support structures, were designed with the same specifications and printed under the same conditions by SLM at 45°, 60° and 75° building angles. Differences in dimensional accuracy, surface roughness, Vickers microhardness, residual stress and microstructure were compared between groups.

The results showed that with support structures, more accurate dimension and slightly higher Vickers microhardness could be obtained. Larger compressive stress dominated and was more uniformly distributed on the supporting surface. Without support structures, the dimension became more precise as the building angle increased and alternating compressive and tensile stress was unevenly distributed on the supporting surface. In addition, the surface roughness of the outer surface decreased with the increase of the built angle, regardless of the support structures. Furthermore, whether the building angle was 45°, 60° or 75°, the observed microstructures revealed that the support structures altered the orientation of the molten pool and the direction of grain growth.

This paper studies the influence of support structures on the workpieces printed at different building angles. Support structures affect the residual stress distribution, heat dissipation rate and microstructure of the parts, and thus affecting the printing quality. Therefore, it is necessary to balance the support strategy and printing quality to better apply or design the support structures in SLM.

This paper traces the incorporation of western educational histories in the development of normal-school curricula during the late Qing Dynasty and the Republic of China (1901–1944). It uses publication networks to show how the study of comparative educational history facilitated the international circulation of knowledge in the teaching profession, and how the “uses” of educational history were shaped by larger geopolitical forces.

This paper analyzes the international exchange of texts between normal schools in China and Japan and, subsequently, between normal schools in China and the United States. A database of 107 publications in the field of western educational history that were adopted in China reveals specific patterns of textual citation, cross-reference, and canon-formation in the field of educational historiography.

With conclusions derived from a combination of social network analysis and clustering analysis, this paper identifies three broad stages in China's development of normal-school curricula in comparative educational history: “Japan as Teacher,” “transitional period” and “America as Teacher.”

Statistical analysis can reveal citation and reference patterns but not readers' understanding of the deeper meaning of texts – in this case, textbooks on the subject of western educational history. In addition, the types of publications analyzed in this study are relatively limited, the articles on the history of education in journals have not become the main objects of this study.

This paper uses both quantitative and qualitative methods to uncover the transnational circulation of knowledge in the field of comparative educational history during its formative period in China.

Aiming at the key issue of interpersonal interaction process between successors and top management teams in the context of family business trans-generational entrepreneurship, this paper aims to explore the motivation, action and results of interpersonal conflict between these two subjects mentioned above.

This paper uses grounded theoretical research methods based on the research objects of three family businesses with both inheritance and transformation needs.

Motivation difference, mediation mode and relationship utilization, that is, the successor and top management team take the goal-orientation, interest orientation and rational tendency as the starting point for relationship coordination. Then it mediates the interpersonal conflicts through compromise, collaboration and compliance, and ultimately provide successors with resources, opportunities, capabilities and motivation advantages to promote trans-generational entrepreneurship. Second, the path of relationship coordination comes from the background of social embedding, that is, the motivation difference comes from the embedding of motivation seeking, the mediation mode comes from the embedding of mediation elements and the relationship utilization comes from the embedding of relationship optimization. The research conclusions not only provide a theoretical framework for family businesses to solve the problems of interpersonal conflicts faced by family businesses but also have practical guiding significance for the trans-generational entrepreneurship.

There are two theoretical contributions in this study. First, the research starting point of social embeddedness theory from the perspective of interpersonal relationships at the microlevel is revised. Since Granovetter (Granovetter, 1985) put forward the theory of social embeddedness, its research scope has been gradually expanded, but the mainstream research in the past focused on analyzing the social network embeddedness of enterprises to obtain social capital from the macro- and meso-level (Nahapiet and Ghoshal, 1998). In fact, this may deviate from the essential interpretation of Granovetter’s theory of social embeddedness, while this study returns to the study of interpersonal relationships. Second, a theoretical model of relationship coordination for successors and top management team is put forward in general. On the basis of the motivation, action and result of interpersonal interaction between the successor and top management team, the interpersonal coordination action path and embedded logic during trans-generational entrepreneurship of family businesses are revealed, which enriched the research scope of social embedded theory in family business.

This study explores configurations that promote the development of collective economies in China's rural villages and reveals the multiple development pathways that otherwise remain relatively unexamined in the literature.

The authors obtained first-hand representative case data from 20 villages in 12 counties in 5 provinces in East, West and Central China via fieldwork and applied fuzzy set qualitative comparative analysis (fsQCA) to conduct a configurational comparative study of the development of village collective economies.

This paper identifies five factors in the current literature that affect the development of village collectives, based on an “entrepreneur–situation” analytical framework. Using the fsQCA method, this study further obtains two main configurations of conditions that culminate in the growth of rural collective economies in China. The first solution is the “top-down path”: When entrepreneurial leadership (EL), resource endowment (RE) and government assistance (GA) are present, a village collective economy will experience a high level of development, irrespective of policy support (PS) and villagers' participation (VP). The second solution is the “bottom-up path”: When EL, VP and PS are present and GA is not present, a village collective economy will experience a high level of development, irrespective of RE. In both situations, EL stands out as the core condition for the development of village collective economies, implying the need for the government to vigorously cultivate the entrepreneurial skills and aspirations of village cadres.

Taking a configurational perspective and using an fsQCA approach, this research constructs an “entrepreneur–situation” analytical framework to investigate the key combinations of factors and pathways involved in the high level of development of Chinese village collective economies.

This study explores the influence of parasocial interaction (PSI), brand credibility and product involvement on celebrity endorsement, and how PSI interacts with brand and product factors and affects celebrity endorsement synthetically.

This study employs a 2 (high/low product involvement) by 2 (high/low brand credibility) between-subjects factorial design experiment to test the hypotheses.

Brand credibility has a positive effect on followers' attitudes toward advertising and products, and product involvement influences its moderation. PSI has salient positive effects on followers' attitudes and behavioral intention, regardless of high/low product involvement. Brand credibility mediates PSI's influence on celebrity endorsement.

The results reinforce the significant effect of PSI on endorsement effectiveness and brand credibility, show the influence of brand credibility and product involvement and show how their influence conditionally interacts with others.

The corporate advertiser should prefer a high PSI celebrity as their endorser. The advertising message design on the microblog also deserves the attention of advertisers.

This study is the primary attempt to construct an integral model to demonstrate the synthetic effect and interaction process of consumers' perception of the endorser, brand and product category factors on celebrity endorsement within the social media context.

Previous research has considered human motivation as a determinant of inquisitiveness, learning and innovation. However, how student’s motivation affects both exploitative/exploratory research outcomes has not yet been sufficiently addressed. The purpose of this paper is to examine self-determination theory (SDT) as a conceptual tool to understand post-graduate student’s academic motivation and how it affects two types of ambidextrous outcomes (exploitative and exploratory), and thus posit relational capital as an important mediator in the motivation–innovation process.

The authors draw conclusions using 331 valid post-graduate foreign scholars data collected via online survey in three Chinese Universities and conduct data analysis using the structural equation modeling technique (AMOS).

Results indicate that: academic motivation and perceived collaboration capability both has a significant effect on exploitation behavior; there was no significant relationship between academic motivation and tendency to collaborate with actors within their networks; collaboration capability and exploitation behavior mediate the relationship between academic motivation and exploration behavior; and further a complementary link was found to exist between exploitation behavior and exploration behavior in students attempt to be ambidextrous.

The authors advance innovation research by expanding SDT to include relational perspective as an antecedent of ambidexterity (exploration/exploitation behaviors) and provide new insights into current understanding of research engagement in higher education settings. The authors highlight some implications for educational agencies seeking to promote the emergence of psychological and relational conditions to enhance novelty in post-graduate internationalized education.

Monascus pigment was widely applied in food processing industry as functional additive, so more attention was paid to the fermentation optimization of pigment production. Therefore, this paper aims to evaluate the best possible fermentative conditions for maximum production of biopigment using submerged fermentation (SFM) and solid state fermentation (SSF) by Monascus purpureus HBSD 08.

The biopigment was produced by using an SMF and an SSF with optimized substrate to achieve higher yield. The antioxidant activity was evaluated by DPPH radical scavenging ability, superoxide anion radical scavenging ability and hydroxyl radical scavenging ability. The pigment composition was analyzed by thin layer chromatography.

Maximum Monascus pigment production (79.6 U/ml and 1,102 U/g) were obtained under an SFM and an SFF. The antioxidant activity of the pigment in an SFM was significantly higher than that in an SFM. The composition of pigment was not different in an SFM and an SFF.

The study developed new conditions, and Monascus strain was a candidate for producing pigment in an SFM and an SFF. To the authors’ best knowledge, this is a first attempt toward comparative evaluation on antioxidant capacity and composition between pigment in an SSF and an SFM. This result will serve for Monascus pigment production.

In the past 70 years since the founding of the People’s Republic of China, China’s economic studies have been constantly centered on major issues such as national modernization, social economic development and the establishment, reform and improvement of socialist economic system. The paper aims to discuss this issue.

It has experienced a process of transition from the establishment of traditional Soviet’s paradigm of political economics to that of modern economics, during which drastic changes have been observed in various aspects of China’s economics, including research content, scope and methods.

Based on that, a discipline system of economics in line with international economics has been initially established. Currently, under the guidance of Marxism, scholars in China’s economics actively draw on the beneficial knowledge system and analytical methods from modern economics, emancipate their minds, seek truth from facts and constantly fortify confidence in the socialist path, theory, system and culture, continuously enhance the discourse power of China’s economics in global economic governance system, so as to push forward to the building of a theoretical system of socialist economics with Chinese Characteristics in the new era.

Economics is a discipline that studies resource allocation and human’s behavior of making a choice based on rationality. Emerged in the industrial revolution and developed in the exploration of a large-scale socialized mode of production and resource allocation system, this discipline has gradually become a broadly explanatory force in social sciences which profoundly affects the economic decision-making behaviors of the government and various economic entities.
