The purpose of this paper is to provide a method with convenient modelling as well as precise computation to the research of complex multi-body system, such as robot arms and solar power satellite. Classical modelling method does not always fit these two requirements.

In this paper, tensor coordinates (TC) and homogeneous tensor coordinates (HTC) method with gradient components are developed, which also have a convenient interface with classical theory.

The HTC proved its precision and effectiveness by two examples. In HTC model, equations have a more convenient form as matrix and the results coincide well with classical one.

There is no plenty detailed operations supported in mathematics yet, which may be developed in further research.

With TC/HTC method, the research work can be separated more thoroughly: a simpler modelling work is left to scientists, when more computing work is handed to the computers. It may ease scientists’ brains in multibody modelling.

The HTC method has the advantages of absolute nodal coordinate formulations, tensor and homogeneous coordinate (HC) and it may be used in multibody mechanics, or other related engineerings.

The idea of relating health, education and other social sector variables with growth and development, or trying to find any convergence among similar countries with respect to such macroeconomic indicators is the basic idea of this chapter, which explores the concept of enhancing welfare through a subjective route, specifically by way of expenditure in health care. By way of testing σ- and β-convergence of current healthcare expenditure per capita of the BRICS countries for the period 2006–2018, it has been found that these countries catch up with significant convergence. It has also been obtained through panel data analysis that such convergence is significantly explained by gross domestic product (GDP) per capita, life expectancy at birth, elderly ratio, CO₂ emissions and prevalence of undernourishment, all of which are in accordance with conventional hypotheses. This chapter claims that, by way of convergence, the BRICS nations may emerge as a new economic power, and expenditure on health care is one of the major areas, among other social sector variables that will play an important role.

“Fostered idols” refer to entertainment idols and young stars-in-the-making who begin their careers as amateurs. Today, the fostered idol model has become increasingly popular in China, and fans demonstrate incredible consumption power. Despite the booming market, little is known about this phenomenon. Therefore, this study aims to explore fans’ motivations and consumption practices from the consumer’s perspective within the framework of self-determination theory.

In all 20 in-depth interviews with fostered idol fans were conducted through online phone calls. The interviews were recorded, transcribed and subsequently analysed using a grounded approach.

The results indicate that fans’ consumption practices are motivated both intrinsically and extrinsically. Intrinsic motivation includes sensory pleasure while extrinsic motivations are composed of a sense of being needed and a sense of success. Extrinsic motivations play a dominant role and reflect the needs of relatedness and competence. Additionally, consumption practices are found to be consistent with motivations.

The results show the crucial role of psychological satisfaction experienced by fans in the consumption of the fostered idol and highlight the importance of a relatedness- and competence-supportive environment to secure fans’ persistent consumption and loyalty.

This study focuses on fans of fostered idols that has not been explored in existing studies and offers valuable insights regarding the similarities and differences between fan consumption in China and other Asian countries. The results will inform marketing practitioners for the development of effective strategies and business decisions.

The purpose of this paper is to examine the effects of China's official household residential status (hukou) on perceived human resource management (HRM) practices, perceived organizational justice (POJ) and its moderation of the relationship between them.

The data for the study were collected from 775 employees in 36 companies in China. Missing data analysis was conducted in order to identify the pattern associated with personal demographic variables. A one-way between-groups MANOVA was performed to investigate hukou differences in the perceptions of HRM practices and POJ. Confirmative factor analysis was conducted on POJ's three-factor measurement model to examine the distinctiveness of the study variables.

Employees registered as agricultural, i.e. rural, hukou, who have migrated to and found employment in urban areas, perceive HRM practices and distributive and procedural justice less favourably than do non-agricultural, i.e. urban, hukou. It also finds that hukou status moderates the effect of HRM on POJ. The findings therefore are that HRM that differentiates rural hukou and urban hukou results in different impressions of their employing organizations, and that hukou status changes the strengths of the relationship between HRM and employees' perceived fairness in their organizations.

The use of the single data source is more likely to result in common method variance which may bias the strength of the relationships that this study proposed. Moreover, this study contributes to the literature with regard to the moderating effects of personal demographic variables on the relationship between organizational policies and POJ, but hukou is the only personal variable examined and therefore the generalisation of the study's findings may be limited. Future research should examine the moderating effects of other personal factors.

The moderating effect of personal demographic variables has been constantly examined in management and psychology research, but with a focus on employees' work attitudes and behaviour. For example, gender was found to moderate the relationship between organizational commitment and turnover intention. The extent to which personal demographic variables might moderate the relationship between organizational policies and POJ has not hitherto been examined. This study fills this void.

The purpose of this paper is threefold: to measure and compare the degree of social media use (SMU) by football clubs, to assess football fans’ engagement with content posted by football clubs (FCs) and to evaluate differences in user engagement with commercial social media advertisement targeting football fans, based on the advertisements’ appeal.

This paper employs three approaches. First, it uses the corporate social media use (CSMU) model to analyse 20,954 Facebook, YouTube, Instagram and Twitter postings from 78 European FCs. Second, it develops a categorisation for social media postings and uses ANOVA and Scheffè tests to conduct a pairwise comparison. Third, it uses a fictional hedonic low-involvement product (chocolate bar) to conduct an experiment by creating a Facebook advertising campaign with three advertisements that are manipulated regarding their general appeal.

Study 1 demonstrates that individual FCs show big differences between their degree of SMU. There are, however, no differences between European leagues, social media platforms, or more/less successful FCs. The results of Study 2 indicate that social media users like, comment and share postings by FCs independently of the content of the posting. Study 3 reveals that both user engagement and reach of advertisements can be substantially increased by employing football-related appeals.

This paper helps understanding consumer engagement in social media. The results presented are relevant and helpful for a multitude of actors, including FCs and other sports clubs, companies targeting football fans and researchers interested in social media and sports marketing.

This paper aims to investigate and prepare the composite polyurea greases with excellent thermal stability and tribological properties.

In this paper, composite Ba-based (Ba, barium) tetra-polyurea lubricating greases were prepared with two different methods: mixing Ba-based gelatinizer and tetra-polyurea gelatinizer by a physical method; and introducing barium carboxylate into tetra-polyurea molecules by a chemical method. The properties of the products, such as heat stability, water resistance and friction performance, were analyzed with thermogravimetry, water-resistance test and four-ball friction test.

The results indicated that the products obtained by chemically introducing barium carboxylate into tetra-urea molecules showed better elevated temperature tribological properties, and the disadvantages of the polyurea greases with high temperature hardening were also obviously improved. The cone penetration rate at 180°C for 24 h is only 3 per cent. The friction coefficient can be decreased to 0.44 and the last non-seizure load value was increased from 560 N to 1,120 N without any other additives.

The research is significant because the prepared composite grease showed excellent performances, such as the outstanding thermal stability, water resistance and excellent extreme pressure and anti-wear properties, which may be widely applied in steel, metallurgy, bearings and other industrial fields.

“Idol pilgrimage tour” is a popular trend among young Chinese fans who travel for idol-related purposes, engage in interactive events and have co-created experiences at destinations. With the growing market size of fan economy, fan tourists generate significant revenue for the local. However, many destinations have not fully utilised this opportunity, and there is a lack of research on this niche form of tourism. This research was undertaken to address this research gap.

This study adopted an idol worship–motivation–co-created experience–tour satisfaction–destination loyalty framework in the context of idol pilgrimage tours. In addition, this study investigated the direct influence of idol worship on the other four constructs. Data were collected from 354 Chinese fans who had such experience through online questionnaires. The partial least squares–structural equation modelling technique was used to examine the research model.

It was demonstrated that idol worship has a direct influence on motivation, co-created experience, satisfaction and loyalty and that there is a positive relationship between motivation, co-created experience, satisfaction and loyalty. The results advance the brand sacralisation literature by studying worship in a tourism context and contribute to interactive marketing literature by clarifying the interactive mechanism between relationships among the idol, fans and destinations. The study suggests some practical implications for destination management organisations attempting to target tourist fans.

This is the first study introducing the concept of the idol pilgrimage tour. Empirical results of this study reveal the underlying mechanism of how idols influence fans' travel-related psychology and behaviour.

Considering the network externalities of online selling, this paper builds three different online direct selling models: manufacturer direct selling (MN model), network platform direct selling (NN model) and retailer direct selling (RN model). The optimal advertising and pricing decision and corporate profits under each selling model are investigated.

Combining the characteristics of online direct selling, this paper formulates direct selling models that are dominated by different companies as Stackelberg game models. Numerical analyses are carried out, along with the comparison of the equilibrium solutions for each model.

The authors' research shows that increasing network externalities is conducive to the development of enterprises. The network platform's profit is the lowest in the RN model and the highest in the NN one. The comparison of manufacturers' profits between the MN model and the NN model primarily depends on consumers' sensitivities for sales price and advertising promotion level. The manufacturer does not benefit from the RN model due to the lowest efficiency.

Coupled with three different online direct selling models and detailed analyses of the optimal solutions, this study has enriched the theoretical foundation of online direct selling. Moreover, this study extends the research of network externalities to the field of e-commerce, revealing the network externalities' influence on the decision-making of the e-supply chain.

Due to social transformation in China, more than 100,000,000 people are migrating within the country. Many parents are forced to leave their children behind when they migrate. In 2008, 58,000,000 children were living as left‐behind children, mainly in the rural parts of China (Zhang, 2009).Migration and its accompanying stressors may affect the mental health of the left‐behind children. This unique literature review of Chinese literature summarises the present state of knowledge and reviews the influential factors. Possible approaches to intervention and system reforms are discussed.A literature review was performed of published studies between 2001 and 2008. Databases used were Fujian Medical University Library Interface, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Information. The Chinese word for ‘left‐behind’ was used as a key word. Books, book chapters, monographs and studies on caring were searched electronically and by hand. Altogether, 53 items were found, discussed and grouped together. Migration affected the mental health of the left‐behind children in a passive way, especially their emotions and social behaviour.There is still controversy over how serious mental health problems are among children who have been left behind. Life events, personality, coping strategies and social suppor t can be regarded as four main factors that are predictive of mental health, which provides theoretical guidance for intervention. Suppor t and prevention of mental health problems in schools, in families and in primary care should be developed and studied.

This study aims to lay the groundwork for the potential application of value management (VM) in construction projects. This paper presents a critical review on the status of VM in a developing country and highlights the role of perceptions on critical success factors (CSFs) for the phases of VM studies, as the participants in a VM study should consider CSFs tailored to the local context.

A series of interviews and a questionnaire were conducted to understand the drivers, perceptions, barriers, and CSFs of VM in the Jordanian construction industry. Although descriptive statistics were used to analyze the status of VM, a structural equation modeling (SEM) approach was adopted to highlight the interrelationships between perceptions and the CSFs of the three phases of VM (i.e. pre-workshop, workshop, and implementation).

The descriptive analysis revealed conflicting viewpoints for perceptions and drivers. Most practitioners acknowledged little awareness of VM phases, and the SEM results indicated that perceptions of VM, in terms of its capacity in improving the scope and objectives of the project, and reducing overall costs, most strongly influenced the CSFs of the implementation phase in terms of support and clear plan for implementation, and had the least influence on the pre-workshop phase. Further, the perceptions had a moderate effect on the CSFs of the workshop phase and it tended to be positive, highlighting the importance of function analysis in this phase.

This is the first study to reveal the status of VM in Jordan in terms of adoption, drivers, perceptions, barriers and CSFs; no prior studies have investigated how perceptions can affect the CSFs of each phase of VM and the endorsement of VM by the construction industry. The contributions of this study include linking the perceptions of construction professionals with the CSFs of VM.
