Based on the model of Big-Five personality traits and theories of person–environment interaction, this study aims to investigate the moderating effects of personality traits on innovativeness through knowledge sharing (KS).

A sample of 318 Vietnamese employees was collected. The hypothesized model was tested by using partial least squares structural equation modelling.

The results indicate that extraversion, agreeableness, conscientiousness and openness to experience have relationships with innovativeness through the mediating effect of KS. Furthermore, transformational leadership (TL) mitigates the positive relationship between agreeableness and openness to experience and innovativeness.

Based on the research results, the authors suggest several practical implications for enhancing employees' innovative organizational behaviours. Transformational leaders should be aware of and control the relationships with employees high in agreeableness and open to experience to ensure that employees' innovativeness can be freely developed.

This research systematically investigates the effect of each personality on employees' innovativeness. Furthermore, this study contributes to the leadership literature by suggesting the dark side of TL that can negatively influence the innovative ability of employees with certain personality traits.

The purpose of this paper is to examine the mediating effect of cyber-victimization (CV) and the moderating effect of academic stress (AS) in the link between smartphone addiction (SPA) and psychological distress (PD) among a sample of Vietnamese college students.

A total of 423 college students participated in this study. Measures of SPA, CV, AS and PD were used for data collection. Using PROCESS macro software (Model 4 and Model 1) and the bootstrapping method, the author performed a mediation analysis and a moderation analysis.

Results indicated a significant mediating effect of CV in the link between SPA and PD. Moreover, this relationship was moderated by AS.

The findings could serve as a guide for future research and mental health professionals.

This study aims to examine the relationship between human resource development (HRD) and the interaction between corporate social responsibility (CSR) and marketing capabilities in small and medium enterprises (SMEs) in the food industry.

This research uses the extended regression model on a sample of 2,649 food SMEs in Vietnam.

This research found that CSR and marketing strategies positively influence HRD; the interaction of CSR and marketing capabilities has a negative effect on HRD; the endogenous role of network capabilities on the effects of CSR and marketing capabilities on HRD.

This research helps food companies use their resources in allocating resources for CSR and conduct marketing reasonably and effectively. This study highlights that the impact of CSR and marketing on HRD is dominated by endogenous networking.

This paper aims to explore factors influencing apartment price volatility in the two biggest cities in Vietnam, Hanoi and Ho Chi Minh City.

The study uses the supply and demand approach and provides a literature review of previous studies to develop four main hypotheses using four determinants of apartment price volatility in Vietnam: gross domestic product (GDP), inflation rate, lending interest rate and construction cost. Subsequently, the Vector Error Correction Model (VECM) is used to analyze a monthly data sample of 117.

The research highlights the important role of construction costs in apartment price volatility in the two largest cities. Moreover, there are significant differences in how all four determinants affect apartment price volatility in the two cities. In addition, there is a long-run relationship between the determinants and apartment price volatility in both Hanoi and Ho Chi Minh City.

Limitations related to data transparency of the real estate industry in Vietnam lead to three main limitations of this paper, including: this paper only collects a sample of 117 valid monthly observations; apartment price volatility is calculated by changes in the apartment price index instead of apartment price standard deviation; and this paper is limited by only four determinants, those being GDP, inflation rate, lending interest rate and construction cost.

The study provides evidence of differences in how the above determinants affect apartment price volatility in Hanoi and Ho Chi Minh City, which helps investors and policymakers to make informed decisions relating to the real estate market in the two biggest cities in Vietnam.

This paper makes several recommendations to policymakers and investors in Vietnam to ensure a stable real estate market, contributing to the stability of the national economy.

This paper provides a new approach using VECM to analyze both long-run and short-run relationships between macroeconomic and sectoral independent variables and apartment price volatility in the two biggest cities in Vietnam.
