This study examined the role of moral disengagement dual system of self-control in the relationship between parental psychological control and cyberbullying.Participants were involved 802 vocational college students(46.01%females;M=18.11,SD=1.23).They completed measures on parental psychological control,moral disengagement,dual system of self-control(impulse and control system),and cyberbullying.The results from mediation-moderation analysis indicated that parental psychological control directly predicts higher cyberbullying.Specifically,moral disengagement partially mediated this relationship,as higher parental psychological control increases moral disengagement,which in turn elevates the risk of cyberbullying.Furthermore,parental psychological control moderated the relationship between parental control and cyberbullying through impulse control systems within the dual system of self-control.Individuals with high impulsivity scores are more likely to engage in cyberbullying when exposed to high levels of parental psychological control,whereas individuals with low impulsivity scores exhibit a lower incidence of cyberbullying. 展开更多

The surrounding rock in tunnelling engineering and coal mining will sometimes be exposed to high temperature. Rock failure is the result of energy dissipation, and the study of the evolution and transformation behavior of energy is of great significance for the in-depth understanding of the deformation and failure of rock after high temperature. This study analyzed the intrinsic connection between mechanical properties and acoustic emission(AE) energy under temperature effect. Based on the energy dissipation and release theory, the distribution and transformation of energy was analyzed, and the energy selfincentive and self-inhibition(EII) model was further established. The main findings are that temperature effect affects the confidence interval trend and the value of AE energy rate, which is related to the change in mechanical properties. The ability of sandstone to store elastic strain energy after exposure to high temperature is independent of the mechanical properties. In this study, the ratio of dissipated energy to elastic energy is used to characterize the stable state of the sandstone system, which can be used as the energy indicator of rock failure precursor. During the absorption, storage, and release of energy before the peak stress, there exists self-incentive and self-inhibition of energy(control behavior). 展开更多

This study examines the correlation ~mong a number of personal and environmental resources that can recluce u^pz-~on, These are: religiosity, happiness, social support, and self-controL The participants in the study consisted of 219 Arab students from teacher training colleges in the Triangle region in central Israel. The findings indicate that all the resources that were examined contribute to reducing the level of depression; in other words, significant negative correlations were found between the level of religiosity, happiness, social support and self-control on the one hand, and the level of depression on the other hand. These findings are consistent with those of other studies conducted elsewhere in the world on different populations CChristian and lewish, as well as Muslim). The present study and its findings are, however, the first to address the understanding of depression among the populace in question. The findings were discussed in accordance with a number of different theories. 展开更多

Previous studies have found that self-control training was effective in improving an individual’s self-control,which plays an important role in inhibiting negative emotions.However,it is unclear whether self-control training can facilitate refraining from retaliation.This study randomly assigned participants(N=55)to a training condi-tion(building self-control by avoiding sweets)or a control condition.Before and after training,participants com-pleted the Transgression-Related Interpersonal Motivations Inventory-18(TRIM-18)and a modified Taylor aggression task once each.Participants in the training condition inflicted more low-intensity penalties on the pre-vious offender compared to control participants.Participants in the training condition reported lower revenge scores after training than before training.These results provide preliminary support that providing people who wish to forgive self-control training might promote forgiveness. 展开更多

Cats placed in the situation of a choosing between a high-value time-delayed and a low-value immediate food rewards elected to wait for the preferred reward or to obtain the worse reward quickly. On the basis of the selected behavior strategy the cats were classified into three groups - self-control ones, choosing predominantly a delayed high-value food reward, impulsive, choosing predominantly an immediate low-value food reward, and ambivalent - with mixed types of reactions. The correlated firing between simultaneously recorded neurons in prefrontal cortex (PFC), n. accumbens (NAcb) and dorsomedial striatum (DMStr) during choice behavior task was studied. It was revealed that a total number of NAcb functional neuron interactions at cats showing self-control reactions exceeded that of observed at ambivalent and impulsive cats. The number of PFC and DMStr functional correlated firing at impulsive and ambivalent cats was more significant than at cats capable to self-control. Observed correlated firing between PFC and NAcb neurons (fronto-accumbal interactions) progressively increased with the shift of behavior to impulsiveness and decreased with self-control behavior. Our results demonstrate that performance of impulsive and self-control behavior alters the correlation structure of neural firing in PFC, NAcb, DMStr and suggest the key role of local PFC, NAcb, DMStr networks in realization of choice behavior. 展开更多

Self-control is an important cornerstone for the academic achievement and long-term successful development of college students.This study developed a localized system of observation indicators for self-control based on a systematic review of the multidimensional theoretical concepts of self-control and the behavioral manifestations of self-control deficiency among Chinese college students.Using China’s longitudinal data of college students,it explored the driving effects and mechanisms through which self-control influences academic achievement.The findings indicated that self-control deficiency among Chinese college students manifests in characteristics such as failure in controlling efforts,failure in delaying gratification,unhealthy sleep habits,and symptoms of digital distraction across academic,daily life,and online domains.Through the mediating role of academic engagement,self-control significantly drives both concurrent and long-term academic achievement of students.This study offers scientific support for higher education institutions to enhance self-control among students and safeguard the caliber of talent cultivation. 展开更多
