Since learners’ academic achievement is the ultimate goal of any system of education, multitudes of studies have been conducted on this variable and its determinants. That is, several scholars have explored the effects of student-related and teacher-related factors on learners’ academic achievement. Notwithstanding, a few researchers have investigated the effects of teachers’ self-efficacy and creativity on learners’ academic achievement. Furthermore, no study has reviewed the role of these teacher-related factors in learners’ achievement. Therefore, the present study seeks to bridge the (...) lacunas by delving into the influence of teachers’ self-efficacy and creativity on English as a Foreign Language learners’ academic achievement. The beneficial effects of self-efficacy beliefs and creative teaching were outlined through the existing evidence. This seems to be illuminative for EFL teachers. Given the positive consequences of teachers’ self-efficacy for students’ achievement, EFL teachers should believe in themselves and their abilities to lead their students to academic success. Additionally, with regard to the positive impact of teachers’ creativity on learners’ achievement, EFL teachers are expected to teach the course content creatively. (shrink)

Bankruptcy of listed companies or shareholders delisting usually causes the crisis spreading in stock markets. Based on the systematic analysis of the epidemic diseases and rumors spreading on the complex networks, the SIR model is introduced to research the crisis spreading in shareholding networks of listed companies and their main holders on the basis of the data about ownership structure in Chinese Stock Markets. The characteristics of shareholding networks are studied, and the parameters for the SIR model are obtained by (...) empirical approach. Then, the numerical computation method is successfully used to analyze the crisis spreading in the networks when the networks meet random failures or intentional attacks. We find the networks have good robustness against the random failures. However, the crisis will spread at a high speed and cause catastrophic damage if there are some failures or attacks on hub vertices in the networks. Under this condition, the networks show obvious vulnerability. Last but not least, the controllability of the networks under the condition of intentional attacks and random failures is studied. The results show that if the network is controlled globally, it is more reliable to allow a politically good new or an appropriate exciting economical policy to play the role in orienting markets under the control of public opinions as the crisis occurs. However, under normal circumstances, controlling a small part of driver vertices representing listed companies, applying appropriate control strategies, and using its characteristics of high efficiency of sending information can effectively control the stock market. Our research provides a new reference to further exploration about the transmission mechanism of the crisis based SIR model and further research on the controllability of crisis spreading in financial markets.

It is important to identify the developmental antecedents of externalizing behavioral problems in early childhood. The current study examined the main effects of maternal personality and its interactive effects with child temperamental reactivity in predicting child externalizing behavioral problems, indicated by impulsivity and aggression. This study was composed of 70 children (Mage= 17.6 months, SD = 3.73) and their mothers. The results showed that maternal agreeableness was negatively associated with child impulsivity. Child temperamental reactivity moderated the effect of maternal conscientiousness (...) on child impulsivity in support of the differential susceptibility model. Specifically, for highly reactive children, maternal conscientiousness was negatively associated with child impulsivity whereas this association was nonsignificant for low reactive children. Child reactivity also moderated the contribution of maternal neuroticism to child impulsivity. That is, maternal neuroticism was negatively associated with impulsivity, only for highly reactive children. (shrink)
