摘要：
INTRODUCTION: This study aims to explore the relationships among psychological capital, learning motivation, emotional engagement, and academic performance for college students in a blended learning environment. METHOD: The research consists of two studies: Study 1 primarily focuses on validating, developing, revising, and analyzing the psychometric properties of the scale using factor analysis, while Study 2 employs structural equation modeling (SEM) to test the hypotheses of relationships of included variables and draw conclusions based on 745 data collected in a university in China. RESULTS: Findings revealed that intrinsic motivation, extrinsic motivation, emotional engagement, and psychological capital all impact academic performance. Extrinsic learning motivation has significant positive direct effects on intrinsic learning motivation, emotional engagement, and psychological capital. Intrinsic motivation mediates the relationship between extrinsic motivation and academic performance. DISCUSSION: In future blended learning practices, it is essential to cultivate students' intrinsic learning motivation while maintaining a certain level of external learning motivation. It is also crucial to stimulate and maintain students' emotional engagement, enhance their sense of identity and belonging, and recognize the role of psychological capital in learning to boost students' confidence, resilience, and positive emotions.
摘要：
Non-suicidal self-injury seriously harm the physical and mental health of adolescents. The aim of the current study was to explore the relationship between non-suicide self-injury, depression, and childhood trauma from the perspective of symptoms in adolescents. A cross-sectional survey was conducted in four junior high middle schools and collected 2640 valid questionnaires. There were 1329 male students and 1311 female students. The age of the participants ranged from 11 to 17 years old, with a mean age of 13.3 (± 0.94) years. Non-suicidal self-injury (NSSI), depressive symptoms, and childhood trauma were assessed using the Adolescent Self-Harm Scale, the Childhood Depression Scale, and the Childhood Trauma Questionnaire, respectively. A network analysis was performed. In the network, NSSI, depressive symptoms, and childhood trauma were closely related. Negative self-esteem in the depressive symptoms and emotional abuse in childhood were the most central nodes. Negative self-esteem and negative mood were directly connected to NSSI, other nodes of depressive symptoms appeared to be indirectly connected to NSSI through these two nodes. Emotional abuse was the only node in childhood trauma categories directly connected to NSSI. Nodes of other categories of childhood trauma (physical neglect, physical abuse, emotional neglect, and sexual abuse) were indirectly connected to NSSI through emotional abuse. NSSI, depression, and childhood trauma of teenagers were closely related. Individuals who have suffered emotional abuse in childhood were more likely to have depressive symptoms and NSSI. Improving negative self-esteem and negative emotions and reducing emotional abuse may be beneficial in alleviating depression and reducing NSSI in adolescents.

摘要：
Microorganisms have a significant role in regulating the absorption and transportation of Cd in the soil-plant system. However, the mechanism by which key microbial taxa play a part in response to the absorption and transportation of Cd in rice under Cd stress requires further exploration. In this study, the cadmium-tolerant endophytic bacterium Herbaspirillum sp. R3 (R3) and Fe-Mn-modified biochar (Fe-Mn) were, respectively, applied to cadmium-contaminated rice paddies to investigate the effects of key bacterial taxa in the soil-rice system on the absorption and transportation of Cd in rice under different treatments. The results showed that both R3 and Fe-Mn treatments considerably decreased the content of cadmium in roots, stems and leaves of rice at the peak tillering stage by 17.24-49.28% in comparison to the control (CK). The cadmium content reduction effect of R3 treatment is better than that of Fe-Mn treatment. Further analysis revealed that the key bacterial taxa in rice roots under R3 treatment were Sideroxydans and Actinobacteria, and that their abundance showed a substantial positive correlation and a significant negative correlation with the capacity of rice roots to assimilate Cd from the surroundings, respectively. The significant increase in soil pH under Fe-Mn treatment, significant reduction in the relative abundances of Acidobacteria, Verrucomicrobia, Subdivision3 genera incertae sedis, Sideroxydans, Geobacter, Gp1, and Gp3, and the significant increase in the relative abundance of Thiobacillus among the soil bacterial taxa may be the main reasons for the decrease in available Cd content of the soil. In addition, both the R3 and Fe-Mn treatments showed some growth-promoting effects on rice, which may be related to their promotion of transformations of soil available nutrients. This paper describes the possible microbial mechanisms by which strain R3 and Fe-Mn biochar reduce Cd uptake in rice, providing a theoretical basis for the remediation of Cd contamination in rice and soil by utilizing key microbial taxa.

摘要：
<jats:p>Previous studies on social exclusion have focused on its adverse effects, rarely exploring how social re-inclusion can aid recovery from exclusion-induced distress. The level of social re-inclusion that can help individuals recover from social exclusion, and whether the recovery effect is influenced by individual characteristics are unclear. The present experimental study extends the Cyberball paradigm, adding a re-inclusion stage to explore the recovery effects of four levels of social re-inclusion on affect; furthermore, it tests the moderating role of self-esteem in the recovery effect. A total of 154 Chinese college students participated in the experiment. Results showed that (1) recovery was effective when the level of re-inclusion was equal to (replica re-inclusion) or greater than (moderate and high over-re-inclusions) the pre-exclusion level of inclusion, but ineffective when it was below this level (token re-inclusion); (2) the re-inclusion level positively predicted recovery, and this was moderated by self-esteem—the prediction was effective for participants with middle and high self-esteem, but not for participants with low self-esteem. These results are discussed from a group process and self-psychology perspective.</jats:p>
摘要：
The rising prevalence of self-injury among adolescents urges us to explore the risk factor underlying its etiology. While previous research has highlighted the important influence of family factors on self-injury, the mechanisms behind it warrant further exploration. This study constructs three moderated mediation models to explored the longitudinal relationship between family functioning and self-injury, and examined the mediating role of depression and the moderating role of negative cognitive emotion regulation (NCER). Data were collected from 705 middle school students (345 boys and 360 girls; Mage = 13.23 years, SD = 0.87) in Hunan Province, China, through a two-wave quantitative survey conducted six months apart. The participants completed self-report questionnaires on family APGAR index scale, children's depression inventory, cognitive emotion regulation questionnaire, and adolescent self-injury scale. The results indicate that family functioning significantly predicts adolescent self-injury later on (beta = -0.095, p < 0.01). Depression at both Time 1 (T1) and Time2(T2) fully mediates the relationship between family functioning (T1) and self-injury (T2). Regarding moderation effects, NCER (T1) did not moderate the impact of depression (T1) on self-injury(T2) (beta = 0.025, p = 0.43). However, NCER (T2) significantly moderated the effect of depression (T1) on self-injury (T2) (beta = 0.082, p < 0.01). and also moderated the relationship between depression (T2) and self-injury (T2) (beta = 0.127, p < 0.001). These findings support the experiential avoidance model and extend the existing literature by demonstrating that depression played a completely mediating role between family functioning and self-injury, which is not only immediate, but also delayed. Additionally, higher NCER as a risk factor amplified the negative effect of depression on self-injury. It implied that interventions focused on reducing depression and enhancing cognitive emotion regulation may effectively reduce self-injury.
摘要：
<jats:p>Emotional mimicry plays a vital role in understanding others’ emotions and has been found to be modulated by social contexts, especially group membership. However, the neural mechanisms underlying this modulation remain unclear. We explored whether and how group membership modulated emotional mimicry using a multimodal method combining facial electromyography (fEMG) and electroencephalography (EEG). We instructed participants to passively view dynamic emotional faces (happy vs. angry) of others (in-group vs. out-group) and simultaneously recorded their fEMG and EEG responses. Then, we conducted combined analyses of fEMG-EEG by splitting the EEG trials into two mimicry intensity categories (high-intensity mimicry vs. low-intensity mimicry) according to fEMG activity. The fEMG results confirmed the occurrence of emotional mimicry in the present study but failed to find a group membership effect. However, the EEG results showed that participants mimicked in-group happiness and anger more than out-group. Importantly, this in-group preference involved different neural mechanisms in happiness and anger mimicry. In-group preference for happiness mimicry occurred at multiple neural mechanisms such as N1 (at P7, Pz, and P8), P2 (at Pz and P8), N2 (at P8), and P3 (at P7, Pz, and P8); in-group preference for anger mimicry occurred at P1 (at P7) and P2 (at Pz). Our findings provide new neural evidence for the effect of group membership on emotional mimicry by uncovering the temporal dynamics of this effect.</jats:p>

Negative parenting style;Problematic mobile phone use;Adult attachment;Fear of missing out
摘要：
This study aimed to investigate the impact of negative parenting styles on problematic mobile phone use among college students, as well as the chain mediating role of adult attachment and fear of missing out (FoMO). The short-form EMBU, Experience in Close Relationship Inventory, Fear of Missing Out Scale, and Mobile Phone Addiction Index Scale were completed by 1002 college students. Results showed that parental rejection and overprotection were positively correlated with college students' problematic mobile phone use. The chain mediating effect of attachment anxiety(or attachment avoidance) and FoMO between negative parenting styles and problematic mobile phone use was significant. These findings suggest that negative parenting styles are closely associated with problematic mobile phone use among college students, and that adult attachment and FoMO play important roles in this relationship.
