This research examines the underlying psychological process of customers' impulsive buying on social media through the lens of customer inspiration. Drawing on the customer inspiration theory, it identifies the factors influencing customer inspiration on social media from three perspectives: source characteristics, platform characteristics and personal characteristics, which subsequently lead to impulsive buying. Since the conceptualization of source credibility includes three mostly reported components: attractiveness, expertise and trustworthiness, it further contrasts the effects of three dimensions of source credibility on customer inspiration.

A structural equation model of customers' impulsive buying on social media was developed through the lens of customer inspiration. An online survey with 625 participants was conducted to test the hypotheses, and the partial least squares (PLS3) method was used.

This research found that source credibility, social presence and customer innovativeness are antecedents of customer inspiration on social media, which positively influence the inspired-by state of the customers, which impacts the inspired-to state and further leads to impulsive buying. By comparing the three dimensions of source credibility, the authors found that attractiveness and expertise positively affect the inspired-by state, while trustworthiness has no significant effect.

This research establishes the link between impulsive buying and customer inspiration, which provides a new psychological perspective to understand impulsive buying. In addition, it investigates the source characteristics of customer inspiration by comparing the effect of three dimensions of source credibility on customer inspiration, which provides the first evidence for connecting customer inspiration and source credibility.

This research draws on self-determination theory and self-construal theory to investigate the effects of achievement-related gamification features on customers' brand attachment in online brand communities.

Survey data (N = 523) were collected from customers of typical gamified online brand communities. The research model was examined with structural equation modeling using SmartPLS 3.2.

Achievement-related gamification features positively affect customers' brand attachment via the intrinsic motives of autonomy, competence and relatedness, but not extrinsic motives. Relatedness motive exerts the strongest mediating effect between achievement-related gamification features and brand attachment, followed by competence and autonomy. Moreover, interdependent self-construal positively moderates the effects of achievement-related gamification features on intrinsic (autonomy, competence and relatedness) and extrinsic motives.

Theoretically, this study contributes to the brand marketing literature by identifying gamification as a new antecedent for brand attachment. It also contributes to the gamification literature by demonstrating that achievement-related gamification features strengthen brand attachment via intrinsic motives but not extrinsic motives in the specific context of the online brand community. Meanwhile, the relatedness motive exerts the strongest mediating effect between achievement-related gamification features and brand attachment, followed by competence and autonomy. Moreover, this research provides the first empirical evidence that interdependent self-construal moderates the effects of achievement-related gamification features on intrinsic and extrinsic motives. Practically, managers can learn from the results that achievement-related gamification features should be designed to foster customers' intrinsic motives and brand attachment, especially those high in interdependent self-construal levels.

With the rapid development of the pipeline transportation and exploitation of mineral resources, it is urgent requirement for the high-performance polymer matrix composites with low friction and wear to meet the needs of solid material transportation. This paper aims to prepare high-performance ultrahigh molecular weight polyethylene (UHMWPE) matrix composites and investigate the effect of service condition on frictional behavior for composite.

In this study, UHMWPE matrix composites with different content of MoS₂ were prepared and the tribological performance of the GCr15/composites friction pair in various sliding speeds (0.025–0.125 m/s) under dry friction conditions were studied by ball-on-disk tribology experiments.

Results show that the frictional behavior was shown to be sensitive to MoS2 concentration and sliding velocity. As the MoS2 content is 2 Wt.%, composites presented the best overall tribological performance. Besides, the friction coefficient fluctuates around 0.21 from 0.025 to 0.125 m/s sliding speed, while the wear rate increases gradually. Scanning electron microscopy images, energy-dispersive spectroscopy and Raman Spectrum analysis present that the main wear mechanisms were abrasive and fatigue wear.

The knowledge obtained herein will facilitate the design of UHMWPE matrix composites with promising self-lubrication performances which used in slag transport engineering field.

The buried pipe element method can be used to calculate the temperature of mass concrete through highly efficient computing. However, in this method, temperatures along cooling pipes and the convection coefficient of the cooling pipe boundary should be improved to achieve higher accuracy. Thus, there is a need to propose a method for improvement.

According to the principle of heat balance and the temperature gradient characteristics of concrete around cooling pipes, a method to calculate the water temperature along cooling pipes using the buried pipe element method is proposed in this study. By comparing the results of a discrete algorithm and the buried pipe element method, it was discovered that the convection coefficient of the cooling pipe boundary for the buried pipe element method is only related to the thermal conductivity of concrete; therefore, it can be calculated by inverse analysis.

The results show that the buried pipe element method can achieve the same accuracy as the discrete method and simulate the temperature field of mass concrete with cooling pipes efficiently and accurately.

This new method can improve the calculation accuracy of the embedded element method and make the calculation results more reasonable and reliable.

We draw on the conservation of resources theory to explore when and how a high-commitment work system (HCWS) improves employees' work well-being.

Data were collected from 64 branches in a high-tech company, involving 64 supervisors and 434 employees to examine the influence of branch-level HCWS on employees' work well-being at individual level.

Consistent with our predictions, the results indicate that a well-designed human resource management (HRM) system (i.e. HCWS) helps to enhance employees' work well-being. Psychological empowerment is seen as an important mechanism linking HCWS with work well-being. The effects of HCWS on psychological empowerment and work well-being are significantly positive only when leader trust in employees is high.

This study indicates a novel resource theoretical perspective regarding the HRM system-employee well-being relationship. It provides insights into how contextual resources (HCWS) enhance employees' work well-being by potentiating the effect of personal resources (psychological empowerment). Just as the old saying goes, “give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime,” the leader trust serves as a critical valve.

With the continuous development of the global COVID-19 epidemic, mobile learning has become one of the most significant learning approaches. The mobile learning resource is the basis of mobile learning; it may directly affect the effectiveness of mobile learning. However, the current learning resources cannot meet users' needs. This study aims to analyze the influencing factors of accepting open data as learning resources among users.

Based on the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT), this study proposed a comprehensive theoretical research model. Data were obtained from 398 postgraduates from several universities in central China. Confirmatory factor analysis was used to determine the reliability and validity of the measurement model. Data has been analyzed using SPSS and AMOS software.

The results suggested that perceived usefulness, performance expectancy, social influence and facilitating conditions have a positive influence on accepting open data as learning resources. Perceived ease of use was not found significant. Moreover, it was further shown in the study that behavioural intention significantly influenced the acceptance of open data as learning resources.

There is a lack of research on open data as learning resources in developing countries, especially in China. This study addresses the gap and helps us understand the acceptance of open data as learning resources in higher education. This study also pays attention to postgraduates' choice of learning resources, which has been little noticed before. Additionally, this study offers opportunities for further studies on the continuous usage of open data in higher education.

The purpose of this paper is to elucidate the influences of the animal fat and fatty acid type on the formation of polycyclic aromatic hydrocarbons (PAHs) and to propose a formation mechanism of PAHs in fat during electric roasting, which is a method of non-direct-contact-flame heating.

The effects of animal fats and model fat on the formation of PAHs were valued on the basis of the ultra high-performance liquid chromatography data. The corresponding products of the FAME pyrolysis were detected by TG-FTIR. The proposal formation mechanism of PAHs was based on the summary of the literature.

Contrary to the International Agency for Research on Cancer, DF had higher risk with 280.53 ng/g of concentration after being roasted than the others animal fats of red meat in terms of PAHs formation. This research also ensured the importance of fat on PAHs formation, the concentration of PAHs in pure fats was higher after being electric roasted than that in meat patties and juice which made from corresponding animal fat. What is more, during pure animal fats and meat products being processed, less PAHs formed in the fat with lower extent of unsaturation and lower content of linolenate. In the same way, methyl linolenate demonstrated the significant increasement to PAHs formation compared to the other fatty acids. And, the number of carbon atom and the extent of unsaturation in fatty acid affects the formation of PAHs during roasting. The detection of alkene and alkane allows to propose a formation mechanism of PAHs during model fat being heated. Further study is required to elucidate the confirm moleculars during the formation of PAHs.

This work studied the effect of the carbon atom number and the unsaturation extent of fats and model fats on the formation of PAHs. This work also assure the important of alkene and alkane on the pyrolysis of model fats. This study also researched the formation and distribution of PAHs in pure fats and meat products after being heated.

The purpose of this paper is to evaluate the experience of visitors with the Janadriyah festival.

An on-site intercept survey was conducted among a random sample of visitors of the festival. The survey was conducted by two field researchers between February 10 and February 25, 2014. A self-administered questionnaire was distributed only to those who agreed to respond to the survey. Out of 200 questionnaires distributed, 28 were incomplete and thus eliminated from the study. As a result, 172 questionnaires were accepted for the purpose of final analysis, representing a response rate of 86 percent.

There is a statistically significant contribution for both the first motivation (I participate in the Janadriyah festival to increase my cultural knowledge) and the fifth one (I participate in the Janadriyah festival to see new and different things and to enjoy a unique atmosphere). There is a statistically significant relationship between the most of services provided and the level of satisfaction. As well as, there is a statistically significant relationship between the perception and the level of satisfaction, also with the word of mouth communication. Finally, the results shown that behavioral intention had a positive influence on word of mouth communication.

There were time limits to this study as the research was conducted during the organization of the Janadriyah festival during its 26th session (February-March 2014).The research was also limited by place as it was conducted at the capital of Saudi Arabia, Janadriyah province.

The model of the study could be applied in similar studies for different festivals all over the world.

Increasing the promotional efforts to attract more visitors from different regions in the world. As it is observed that the vast majority of participants in the Janadriyah festival are local residents. In addition, there is a need to organize training programs to all staff participating in the organization of the festival supervised by academics and professionals. Organizing seminars during the festival in order to increase the awareness of local residents with importance of the cultural heritage and how to keep it. And at the end, the program of the festival has to be updated from one session to another in order to attract more attendees.

The integrated model of the study represent an added value to the research in the field of tourism festivals.

The primary purpose of this study is to investigate the influence of tourists' perceived value, satisfaction and behavioral intention on the development of Lipu Yi costume culture to promote the development of intangible cultural tourism and better construct a model of the influencing factors of Lipu Yi costumes in the development of intangible cultural heritage tourism.

The study site is the intangible cultural district of Panzhihua, Sichuan Province, China. This study examines the interrelationships between tourists' perceived value of experience, behavioral intention and satisfaction as the tourists relate to Lipu Yi costume and intangible cultural heritage tourism. A sample of 225 tourists who had visited Panzhihua at least once was selected for the study.

All seven of the survey's hypotheses were supported. Therefore, this study concludes that tourists' perceived value, satisfaction and behavioral intention directly affect the development of intangible cultural tourism and significantly positively impact the growth of Lipu Yi costumes culture. Descriptive analysis, confirmatory factor analysis (CFA) and structural equation modeling (SEM) investigation methods were used.

This paper analyzes tourists' perceived value of Lipu costume culture and tourists' satisfaction and behavioral intention during the tourism process. This study provides a more in-depth understanding of the relationship between Lipu Yi costume and non-heritage tourism factors. Practical methods and approaches are sought to further develop Lipu Yi costume non-heritage tourism.

This study examined the macroeconomic effects of COVID-19-induced economic policy uncertainty (EPU) in Nigeria. The study considered the effects of three related shocks: EPU, COVID-19 and correlated economic policy uncertainty and COVID-19 shock.

First, the study presented VAR evidence that fiscal and monetary policy uncertainty depresses real output. Thereafter, a nonlinear DSGE model with second-moment fiscal and monetary policy shocks was solved using the third-order Taylor approximation method.

The authors found that EPU shock is negligible and expansionary. By contrast, COVID-19 shocks have strong contractionary effects on the economy. The combined shocks capturing the COVID-19-induced EPU shock were ultimately recessionary after an initial expansionary effect. The implication is that the COVID-19 pandemic-induced EPU adversely impacted macroeconomic outcomes in Nigeria in a non-trivial manner.

The result shows the importance of policies to cushion the effect of uncertain fiscal and monetary policy path in the aftermath of COVID-19.

The originality of the paper lies in examining the impact of COVID-19 induced EPU in the context of a developing economy using the DSGE methodology.
