The study investigates the inter-linkages between geopolitical risk (GPR) and food price (FP).

By employing the bootstrap full- and sub-sample rolling-window Granger causality tests.

The empirical results show that there is a time-varying bidirectional causality between GPR and FP. High GPR leads to a rise in FP, suggesting that geopolitical events usually may disrupt supply and demand conditions in food markets, and even trigger global food crises. However, the negative effect of GPR on FP does not support this view in certain periods. This is mainly because GPR is also related to the global economic situation and oil price, which together have impacts on the food market. These results cannot always be supported by the inter-temporal capital asset pricing model, which states that GPR affects FP in a positive manner. Conversely, there is a positive impact of FP on GPR, indicating that the food market is an effective tool that can reflect global geopolitical environment.

In the context of the Russia–Ukraine conflict, these analyses can assist investors and policymakers to understand the sensitivity of FP to GPR. Also, it will provide significant revelations for governments to attach importance to the role of food price information in predicting geopolitical events, thus contributing to a more stable international environment.

The purpose of this paper is to conduct the synthesization of LiFePO₄-C (LFP-C) with fine particle size and enhanced electrochemical performance as the positive electrode material for Li-ion capacitors (LICs) with neutral aqueous electrolyte.

LFP-C was prepared by using polyethylene glycol (PEG) as a grain growth inhibitor, and the effects of the calcination temperature and PEG content on the structure and morphology of LFP-C were investigated. LICs using environment-friendly, safe and low-cost LiNO₃ aqueous electrolyte were assembled with LFP-C as the positive electrode and active carbon as the negative electrode. The electrochemical performances of LFP-C and LICs were studied.

The results show that the particle size of LFP-C decreases significantly through the introduction of PEG. Cyclic voltammetry results show that the LFP-C prepared at 550°C with 1.0 g PEG exhibits the highest C_pe of 725 F/g at the scanning rate of 5 mA/s. Compared to LFP prepared without PEG, the electrochemical performance of optimized LFP-C dramatically increases due to the decrease of the particle size. Moreover, the LIC assembled with the optimized LFP-C exhibits excellent electrochemical performances. The LIC maintains about 91.3 per cent of its initial C_ps after 200 cycles which shows a good cycling performance.

The LFP-C is the suitable positive electrode material for LICs with neutral aqueous electrolyte. LICs can be used in the field of automobiles and can solve the problems of energy shortage and environmental pollution.

Both the LFP-C with fine particle size and its optimal LIC using environment-friendly, safe and low-cost LiNO₃ aqueous electrolyte own good electrochemical performances.

The sustainable success of infrastructures is becoming a driving force for advancing urbanization globally. However, to achieve infrastructure sustainable success (ISS), how project management practices (PMPs) play their role remains unexplored in current literature. To this end, an empirical study on whether PMPs play significant impacts on the accomplishment of ISS was conducted.

This research is based on an empirical survey of domestic and overseas infrastructure projects managed by Chinese companies. 162 data samples were collected and further analyzed deploying structural equation modeling (SEM) on the basis of goal-setting theory. PMP factors derived from the plan-do-check-act (PDCA) ideology, i.e. culture, strategy, implementation and reflection were hypothesized and validated to have direct and indirect relationships with ISS.

The results of this study indicate that both culture and reflection can directly drive the PMPs toward ISS. Furthermore, it is revealed that by affecting mediator factors of strategy, implementation and reflection, culture is found to present an indirect influence on ISS; by affecting mediator factors of implementation and reflection, Strategy is found to present an indirect influence on ISS and by affecting the mediator factor of reflection, implementation is found to present an indirect influence on ISS.

These findings contribute to the body of knowledge in measuring sustainability success of project management performances by clarifying critical relationships of how PMPs lead to ISS. Prospectively, the outputs of this research will generate informative insights for practitioners to improve their PMPs in the process of pursuing ISS in future infrastructure management practices.

Using survey research, the purpose of this study was to examine perceptions of diversity to examine perceptions of diversity and inclusion among majority and non-majority students at a predominately White university (PWI) and a historically Black university (HBCU) observing any patterns of difference between majority and non-majority groups to make inferences regarding students’ sense of belonging, given current national efforts to establish inclusive excellence on university campuses.

Results based on Likert-scale responses on a validated questionnaire were analyzed using independent samples t-tests to identify differences for each survey item. Eta squared was used as an effect size measure. The PWI and HBCU were then compared by item analysis. A two-way factor analysis of variance (ANOVA) was used to assess the independent impact of each of the universities (i.e. PWI, HBCU) and the interaction of those two factors in their effect on the dependent variables (i.e. race, gender, sexuality).

Results indicated significant differences between the majority and non-majority groups on multiple items within each university site. Further, significant differences were observed between the universities in perceptions and experiences of diversity and inclusion.

Unique in this study was an examination of perceptions of inclusion at a PWI and an HBCU based not only on non-majority status of race, but also on gender and sexuality with the intention of expanding the research base associated with “sense of belonging” to other groups who have existed as “diverse others” in the context of majority culture dominance.

The purpose of this study was to examine the relationship between leisure involvement (LI), conspicuous sport consumption and subjective well-being (SW) for two luxury leisure activities: golf and skiing.

The authors collected data from Guangdong Province (golf, n = 342) and Jilin Province (skiing, n = 310) and examined the proposed model using structural equation modeling (SEM) and tested the mediating effect of conspicuous sport consumption using bootstrapping method.

The findings show that the proposed model explained the relationships among LI, conspicuous sport consumption and SW. Furthermore, the findings suggest that LI and conspicuous consumption (CC) can elevate sport participants' perception of SW, enriching leisure-class theory.

The authors’ findings contribute to the domain of CC in sport participant and leisure research and provide significant implications for the sport tourism marketers.

This paper aims to adopt a moderated mediation model to examine the mediation roles of employee engagement and hindrance time pressure; the moderation roles of personality in the relationship between strengths-based psychological climate and employee innovation performance.

Applying snowball sampling and a self-administered survey, the data were collected from employees and immediate supervisors working in Chinese small-medium-sized enterprises. The PROCESS macro for SPSS was applied to examine the moderated mediation model.

The results show that a strengths-based psychological climate significantly influences employee engagement and hindrance time pressure, which, in turn, affects employee innovation performance. Both extroversion and emotional stability moderate the relationship between strengths-based psychological climate, employee engagement and hindrance time pressure but also the indirect effect of strengths-based psychological climate on employee innovation performance through employee engagement and hindrance time pressure.

Drawing on job demands and resources models, this research focusses on maximizing employee strengths instead of weaknesses and includes both two intermediating mechanisms in-between strengths-based psychological climate and innovation performance. Personality variables are applied as moderators, as the study assumes the effectiveness of the strengths-based interventions may vary depends on individual differences.

This study proposes that a strengths-based psychological climate may shift focusses from employee weakness to strengths to maximise their talents. Also, personality variables are suggested to be considered in the related human resource practices (e.g. hiring and performance appraisal) to increase the fit between employees, their jobs and the organisations.

This study develops a moderated mediation model to investigate the possible mediating mechanisms and boundary conditions in relation to the impact of strengths-based psychological climate on employee innovation performance.

The purpose of this paper is to unveil how family involvement in management teams of private Chinese companies affects professional managers’ psychological ownership and sense of “us”, in the hopes of understanding why their devotion cannot coexist with the higher level of commitment of family managers.

This paper includes two main studies. The first uses regression to analyze survey data provided by 165 professional managers working in Chinese private companies. The second is a scenario experiment in which 106 MBA candidates participate.

The study finds that there is a negative relationship between family management involvement and professional managers’ perceived relationship closeness to owners and psychological ownership of firms. It also finds that relationship closeness fully mediates the negative influence of family management involvement on managers’ psychological ownership.

This paper contributes to both the theoretical literature and management practice. From a theoretical perspective, it connects studies in indigenous sociological psychology with new literature on psychological ownership. The paper finds that personal relationships nurture the shared psychological ownership of managers by generating a sense of “us”, providing a new theoretical explanation for its formation process. Furthermore, this study offers an explanation for the negative signal effect of family involvement in management. From a practical perspective, this study finds that family involvement in management acts as a critical boundary condition for using personal relationships to stimulate professional managers.

The purpose of this paper is to empirically determine the key factors influencing the US consumers’ intentions to use apparel m-commerce.

An enhanced consumer’s apparel m-commerce adoption model was developed through integrating the existing e-commerce/m-commerce theories (i.e. theory of reasoned action, Technology acceptance model and diffusion of innovation theory). The investigated factors included nine independent variables – perceived usefulness (PU), perceived ease-of-use, subjective norm (SN), personal innovativeness traits, security and privacy concerns, compatibility, observability, trust and past non-store shopping experience (PE), and five control variables – age, gender, education level, income level and ethnicity. The dependent factor is consumer’s intention to use (IU) apparel m-commerce. The primary data were gathered by an online survey of US consumers via Amazon Mechanical Turk. In total, 317 eligible responses were received. The applied statistical techniques were factor analysis and multiple regression analysis.

The results show that the US consumer’s IU apparel m-commerce is significantly affected by PU, SN, compatibility and PE and education level. Overall, 67.3 percent of variation in the US consumer’s IU apparel m-commerce is explained by the developed model, which suggests a high explanatory power.

Companies should provide those functions and features on their mobile websites that enable consumers to easily find the products wanted and complete transactions efficiently. Companies should particularly target the consumers with innovativeness traits and/or those having prior non-store shopping experience. Enhancing the trust in m-commerce among the US consumers with higher education level could help companies attract more potential users. Elderly, female or lower income consumers could be the next business opportunities for apparel e-tailers.

As one of the first efforts made to understand the emerging apparel m-commerce phenomenon, this study empirically determined the key factors influencing the US consumer’s IU apparel m-commerce.

The purpose of this study is to examine the effects of the workaholism on work–family conflict via the mediator of psychological detachment from work and the moderator of family-supportive supervisor behavior.

To avoid common method bias, the authors adopted a three-wave data collection with a one-month lagged design. A total of 500 questionnaires were distributed and 322 usable questionnaires were collected. The PROCESS macro for SPSS was applied to test the hypothesized relationships.

Findings demonstrated that workaholism is positively related to work–family conflict; psychological detachment from work mediates the relationship between workaholism and work–family conflict. Moreover, family-supportive supervisor behavior moderates the relationship between workaholism and work–family conflict and between workaholism and psychological detachment from work, respectively. Finally, family-supportive supervisor behavior moderates the indirect effect of workaholism and work–family conflict via psychological detachment from work, such that the indirect effect was weaker when family-supportive supervisor behavior was high.

The study suggests that it is necessary for organizations to be responsible for employee well-being in different domains because the impact of workaholism on physical and mental health may bring unexpected consequences because of the lack of recovery and the loss of resources. This study not only shows the importance for individuals to look for ways to disengage from workplace but addresses the significance of supervisory support from organizational aspects.

This study includes psychological detachment from work as mediator and family-supportive supervisor behavior as moderator to investigate the moderated mediation relationship in the current highly demanding workplace. By applying conservation of resource and role scarcity hypothesis regarding individual resource allocation, the results may shed lights on facilitating individuals distancing from obsessively and excessively working mentality and behaviors that further lessen incompatibility in both work and family domains.

The purpose of this paper is to examine the relationship between sense of calling and work meaningfulness with job crafting as a mediator and spiritual leadership as a moderator.

Adopting a three-wave procedure, data were collected from 333 participants across industries from Guangdong province, China.

Results indicate that job crafting partially mediates the relationship between employee sense of calling and work meaningfulness. Moreover, the positive relationship between job crafting and work meaningfulness is more significant when spiritual leadership is high than when it is low. Additionally, spiritual leadership moderates the indirect relationship of sense of calling and work meaningfulness through job crafting such that the indirect effect of sense of calling is stronger when spiritual leadership is high than when it is low.

Based on self-determination theory, this study adds to current literatures examining the importance of sense of calling on a person's career and explores the boundary conditions, which bring desirable outcomes.
