Four factors—namely, harm avoidance, novelty seeking, reward addiction and persistence—represent the nature of temperament that is not genetically determined in itself. It was shown in earlier studies that a strong propensity to look for novelty or a tendency to engage in risky behavior is correlated with genetic variants in the area of the genes encoding dopamine receptors. Therefore, the aim of this study is to determine whether there is a relationship between personality traits and genetic variants in the area of the DRD2 dopamine receptor gene in MMA athletes. The participants consisted of 85 mixed martial arts (MMA) athletes and 284 healthy, non-MMA male participants. Their personality traits were measured using the Revised Temperament and Character Inventory. Blood was collected for genetic assays and all samples were genotyped using the real-time PCR method. We observed a statistically significant effect of a complex factor of the DRD2 rs1799732 genotype on MMA participants’ control and reward dependence. Engaging in high-risk sport may be associated with several personality characteristics. The DRD2 rs1799732 polymorphism may be associated with reduced harm avoidance in martial arts athletes, thereby modulating athletes’ predisposition to participate in high-risk sport.

Purpose The purpose of this paper is to examine the effect of entrepreneurs’ personality traits on firm innovation performance through the mediation role of entrepreneurs’ innovativeness. Design/methodology/approach The data consist of 2,574 firms from a survey of small and medium-scale manufacturing enterprises (SMEs) in Vietnam, a developing and transitioning economy where SMEs constitute an integral part of the economy. The estimation results based on the structural equation model was applied to analyze the data. Findings The results indicate that an entrepreneur’s innovativeness is positively associated with his extraversion, conscientiousness, and openness to experience but negatively accompanied with his neuroticism. Besides, the three traits – openness to experience, conscientiousness and extraversion have positive indirect effects, while neuroticism has a negative indirect effect on technological improvement and new technology adoption. However, the effects of agreeableness on entrepreneurial innovativeness and firm innovation performance are insignificant. In addition, the diverse backgrounds of the entrepreneur such as education and ethnics are also found to influence his innovativeness and to have indirect effects on firm innovation performance. Originality/value This study may contribute to the immature literature on the entrepreneurial process within SMEs by presenting empirical evidence on the relationship between entrepreneurial personality traits and firm innovation with a large sample of SMEs in Vietnam, an emerging economy where SMEs constitute an integral part of the economy.
