摘要：
The job crafting literature has not devoted much attention to the effects of specific forms of job crafting, particularly cognitive crafting. The present study builds on Conservation of Resources theory to explain how cognitive crafting might influence work meaningfulness for employees, and in turn, increase their experienced thriving at work. Moreover, we hypothesise that the impact of cognitive crafting on these outcomes is influenced by two motivational job characteristics: skill variety and job autonomy. To test our hypotheses, we collected three-wave survey data from 223 employees employed in a variety of occupations and industries in China. Results indicate that engaging in cognitive crafting enhances employees' work meaningfulness, resulting in thriving at work. Furthermore, skill variety and job autonomy are crucial moderators of these relationships. Specifically, when employees perceived low levels of skill variety or job autonomy, engaging in cognitive crafting was more likely to lead to enhanced work meaningfulness, which in turn resulted in higher levels of thriving at work. Implications for research, theory and practice are discussed.

摘要：
BACKGROUND AND AIMS: The intertemporal and risk decision-making impairments are vital cognitive mechanisms in internet use disorder (IUD). However, the underlying neural mechanisms for these two decision-making dysfunctions in individuals with IUD remain unclear. METHODS: This study employed Functional Near-Infrared Spectroscopy (fNIRS) to record changes in blood oxygen concentration in the prefrontal cortex of individuals with IUD during intertemporal and risk decision-making tasks. RESULTS: The findings revealed that the intertemporal decision-making deficits in IUD group were primarily associated with reduced activation in the left dorsolateral prefrontal cortex (dlPFC) and orbitofrontal cortex (OFC) and FC from the left dlPFC to the right dlPFC. On the other hand, risk decision-making impairments were linked to decreased OFC activation and weakened functional connectivity from the left dlPFC to the right dlPFC and OFC. DISCUSSIONS AND CONSLUSIONS: These results suggested that while there were common neural mechanisms underlying intertemporal and risk decision-making impairments in individuals with IUD, specific neural foundations existed for each type of dysfunction.

摘要：
Objective: External events affect individuals through their cognitive process, a model on how and when negative life events are associated with depressive symptoms was tested by considering individuals' internal and external factors based on the conservation of resource theory (COR).Methods: We conducted a survey to test our hypotheses. Participants were college students who were selected with the cluster sampling method and were asked to complete the scales measuring negative life events, perceived social support, psychological capital (PsyCap), rumination, and depressive symptoms in the classroom with a unit of class. A total of 764 questionnaires were distributed and returned, and 703 valid data were obtained finally.Results: The present study found that (1) the relationship between negative life events and depressive symptoms was moderated by perceived social support negatively, such that the relationship was stronger with low perceived social support; (2) the relationship between negative life events and depressive symptoms was mediated by rumination; (3) the relationship between rumination and depressive symptoms was moderated by PsyCap negatively, such that the relationship was stronger with low PsyCap; (4) the indirect relationship between negative life events and depressive symptoms through rumination was moderated by PsyCap negatively, such that the indirect relationship got stronger with low PsyCap. Conclusion: Rumination is an essential process for negative life events to affect depressive symptoms, PsyCap and perceived social support help alleviate the detrimental effect of negative life events from internal and external perspectives, respectively. Our research conclusion has a theoretical and practical implementation for reducing depressive symptoms in college students.

摘要：
BackgroundAntisocial personality features in adolescents are frequently associated with delinquency and constitute the problem that most concerns the criminal justice system and the public. Hostile interpretation bias has been identified as a candidate for explaining emergent adolescent antisocial personality problems and aggression, but it is unclear whether offenders and non-offenders show differences in the relationships between hostile interpretation bias, aggression and antisocial personality features. AimsTo compare relationships between hostile interpretation bias and a personality measure between incarcerated teenagers and first year university students and to explore aggression and criminal history as mediating or moderating variables. MethodsFifty-three 16-18-year-old incarcerated male offenders and 69 17-20-year-old male university students were recruited, the former through institutional staff and the latter by online advert only. Individuals in both groups self-rated, in private, on the Word and Sentence Association Paradigm-hostile (WSAP), The Ambiguous Intentions Hostility Questionnaire (AIHQ), Hostility Interpretation Bias Task (HIBT) as tests for hostile interpretation bias, and on the Buss-Perry Aggression Questionnaire and on Hyler's Personality Disorder Questionnaire (PDQ-4). Among the students, criminal history was assessed by a self-reported binary question. LASSO regressions were used to test inter-relationships between hostile interpretation bias and aggression or antisocial personality traits. Mediation and moderation were tested using MPLUS 7.4. ResultsThe WSAP and AIHQ, as measures of self-reported hostility bias, had relationships with self-reported aggression (Pearson r 0.24-0.58, p < 0.001) and with antisocial personality features (r 0.36-0.50, p < 0.001), the HIBT did not. Aggression scores mediated the relationship between hostile interpretation bias and antisocial personality features. Furthermore, the relationship between hostile interpretation bias and aggression was stronger among the young offenders (estimates 0.43-0.75) than among the university students without criminal history (estimates 0.13-0.36). ConclusionsHostile interpretation bias appears to promote antisocial personality features by increasing an individual's aggression, regardless of social status, although the effect was much stronger among the young offenders. To reduce young people's antisocial personality features, future studies should perhaps focus on evaluating strategies to reduce hostile bias or prevent it from being expressed in aggressive behaviours.

Multi-layer feedforward network;Weak signal propagation;Neuronal morphology;Network properties
摘要：
The propagation and detection of weak signals play a vital role in the central nervous system's information processing. In this paper, a biophysical two-compartment model is adopted to investigate how the neuronal morphology and network properties modulate signal propagation in a multi-layer feedforward network (FFN). The numerical simulation results show that neurons with larger dendrites have higher firing rates and better responses to weak signals. Similarly, the output layer of FFN constructed by larger-dendrite neurons also exhibits better responses. A suitable chaotic current is necessary for the propagation of weak signals. Excessively strong or weak chaotic current leads to propagation failure. Sparse connection and weak synaptic strength optimize the responses of the output layer, which is consistent with real biological networks observed in the brain. It is found that weak signal propagation in FFN is highly correlated with the regulation of firing rate. Our results may provide novel insights into the modeling of complex networks and network function implementation.
摘要：
The ability to suppress unwelcome memories is important for productivity and well-being. Successful memory suppression is associated with hippocampal deactivations and a concomitant disruption of this region’s functionality. Much of the previous neuroimaging literature exploring such suppression-related hippocampal modulations has focused on the region’s negative coupling with the prefrontal cortex. Task-based changes in functional connectivity between the hippocampus and other brain regions still need further exploration. In the present study, we utilize psychophysiological interactions and seed connectome-based predictive modeling to investigate the relationship between the hippocampus and the rest of the brain as 134 participants attempted to suppress unwanted memories during the Think/No-Think task. The results show that during retrieval suppression, the right hippocampus exhibited decreased functional connectivity with visual cortical areas (lingual and cuneus gyrus), left nucleus accumbens and the brain-stem that predicted superior forgetting of unwanted memories on later memory tests. Validation tests verified that prediction performance was not an artifact of head motion or prediction method and that the negative features remained consistent across different brain parcellations. These findings suggest that systemic memory suppression involves more than the modulation of hippocampal activity—it alters functional connectivity patterns between the hippocampus and visual cortex, leading to successful forgetting.

摘要：
The Ni-Fe composite catalyst has received in-depth research attention due to high intrinsic activity in electrochemical water splitting applications. Corrosion engineering is considered an effective strategy for preparing large-scale Ni-Fe composites to match industrial electrocatalytic electrolyzers. Here, we demonstrate an efficient corrosion strategy to prepare defect-rich Ni(Fe)OOH/Ni(Fe)S-x nanosheet arrays on a NiFe foam within 10 min. The corrosion solution we proposed (containing (NH4)(2)S2O8, (NH2)(2)CS, and FeCl3) has strong oxidizing properties, which releases a large amount of heat when it corrodes the Ni-Fe foam. The heat promotes the hydrolysis of (NH2)(2)CS and creates an alkaline environment for the rapid growth of Ni-Fe composites. Experimental results reveal that Ni(Fe)S-x plays a crucial role in enhancing the oxygen evolution reaction performance of Ni(Fe)OOH/Ni(Fe)S-x. Therefore, Ni(Fe)OOH/Ni(Fe)S-x exhibits remarkable catalytic activity with low overpotentials of 227 and 313 mV to afford current densities of 10 and 1000 mA cm(-2), respectively. Under 270 mV overpotential, the intrinsic catalytic activity of Ni(Fe)OOH/Ni(Fe)S-x is 24.65-fold, 21.09-fold, and 52.21-fold that of FeOOH/FeSx, NiOOH/NiSx, and Ni(Fe)OOH, respectively. Moreover, large-scale Ni(Fe)OOH/Ni(Fe)S-x electrode materials are prepared with a size of 10 x 10 cm(2) on a NiFe foam, implying the huge potential for practical applications. This work offers a new perspective on designing large-scale and highly active oxygen evolution catalysts.

Ostracism;Problematic smartphone use;Social self-efficacy;Rejection sensitivity;The Interaction of Person-Affect-Cognition-Execution model
摘要：
Problematic smartphone use has become a prominent social problem, and factors shaping this behavior have been a research focus. Based on the Interaction of Person-Affect-Cognition-Execution model, we examined the association between ostracism and problematic smartphone use, and individual differences in the relation (i.e., the mediating role of social self-efficacy and the moderating role of rejection sensitivity). A sample of 800 undergraduates were recruited to complete questionnaires. The SPSS PROCESS was used to test the moderated mediation model and the Johnson-Neyman method was used to analyze the moderating effect of rejection sensitivity. As predicted, ostracism was positively associated with problematic smartphone use. Social self-efficacy partially mediated this relation. Rejection sensitivity moderated the relation between ostracism and social self-efficacy—with the association being weaker for students with higher rejection sensitivity. The results have both theoretical and practical implications.

ALFF;early life adversity;family unpredictability;fMRI;self-control
摘要：
Self-control, the ability to regulate prepotent desires or impulses in order to realize one's valued goal, has been found to be associated with early life adversity. However, the neural correlates underlying this relationship remain poorly understood. The present study employed resting-state functional magnetic resonance imaging (fMRI) to investigate this issue among late adolescents (N = 538). Results showed that family unpredictability rather than family harshness of early life adversity was negatively correlated with self-control ability. The whole brain analysis showed that self-control was associated with enhanced ALFF in the right middle and inferior frontal gyrus, the left anterior insula, and with decreased ALFF in the left precuneus. Moreover, the mediating analysis showed that ALFF in the inferior frontal gyrus could partially mediated the association of family unpredictability with self-control ability. These findings suggested that the brain regions implicating in executive control might be the neural correlates underlying the relationship between early life adversity and self-control ability, which advances the mechanistic understanding of how early family environment relates to the development of self-regulation in late adolescence.

Body dissatisfaction;Feminism consciousness;Negative emotional eating;Negative family body talk
摘要：
Negative emotional eating has been increasingly a prominent disordered eating and public health problem among young women, especially during COVID-19. Although previous studies have attempted to explain the relationship between body talk and negative emotional eating, limited studies focused on examining the potential mechanisms, especially the potential protective mechanism. Thus, the current study aimed to examine the relationship between negative family body talk (NFBT) and negative emotional eating, as well as its underlying mechanism - the mediating role of body dissatisfaction (BDIS) and the moderating role of feminism consciousness (FC). A cross-sectional study was employed among a sample of Chinese girls and young women (n=813, M(age)=19.4 years) from a junior college in central China. Participants completed surveys assessing NFBT (Adapted Body Talk Scale), BDIS (Body Image State Scale), negative emotional eating (Dutch Eating Behavior Questionnaire), and FC (Synthesis Subscale from Feminist Identity Composite). A moderated mediation analysis was conducted. The results showed that: (1) after controlling for age and BMI, NFBT was positively associated with negative emotional eating, and BDIS could significantly mediate this relationship (mediating effect=0.03, 95% CI [0.02, 0.06]); (2) FC significantly moderated both the direct relationship between NFBT and negative emotional eating and the relationship between NFBT and BDIS. Specifically, these two associations were not significant for participants with higher FC (+1SD above average). This study deepens our understanding of the relationship between NFBT and negative emotional eating, as well as the protective role of FC. If future studies demonstrate causal relationships, this evidence could point to a need for programs to prevent negative emotional eating in young women by increasing their level of feminism consciousness.

摘要：
Interoceptive sensibility refers to the tendency to focus on internal bodily states and the capacity to detect them. As the subjective dimension of interoception, interoceptive sensibility plays a key role in individuals' health. Self-objectification, a process by which individuals tend to adopt a third-person's perspective of their physical self, leads to decreased interoceptive sensibility. However, few studies regarding the neural basis of interoceptive sensibility and the underlying mechanism of the relationship between self-objectification and interoceptive sensibility have been conducted. In this study, we assessed the resting-state brain activity (fractional amplitude of low-frequency fluctuation, fALFF) and connectivity (resting-state functional connectivity, RSFC) of 442 college students. Whole-brain correlation analyses revealed that a higher level of interoceptive sensibility was linked to higher fALFF in the right inferior frontal gyrus (IFG) and left cerebellum and to lower fALFF in the left paracentral lobule and left superior/middle temporal gyrus. Interoceptive sensibility also was negatively associated with the RSFC between the right IFG and the right secondary somatosensory cortex (S2) and the right IFG and the ventral premotor cortex (VPC). These brain regions and connections are mainly responsible for switching attention to internal/external information and processing body-related somatosensory as well as sensory information. Mediation analyses suggested that the fALFF of the right IFG and the RSFC of IFG-S2 and IFG-VPC mediated the relationship between self-objectification and interoceptive sensibility. Overall, these results suggest that the IFG may be the neural marker of interoceptive sensibility and reveal several potential mediation models of the relationship between brain neural correlates and self-objectification and interoceptive sensibility.
摘要：
Background: As a global trauma event, the Coronavirus disease (COVID-19) hugely impacts people's mental health and well-being. The purpose of our study is threefold: first, investigate the relationship between exposure to COVID-19 and life satisfaction among a large sample in China; second, test the mediating role of hyperarousal in the association between exposure to COVID-19 and life satisfaction; third, explore the moderating/mediating role of affective forecasting in the association between hyperarousal and life satisfaction.Method: The current study recruited 5546 participants to complete a set of self-report questionnaires online from April 22, 2020 to April 24, 2020. The moderated mediation and chain mediation model analyses were conducted using the SPSS software and PROCESS macro program.Results: Exposure to COVID-19 negatively predicted life satisfaction (Effect = -0.058, p < 0.001). This rela-tionship was partially mediated by the hyperarousal level (Effect = -0.018, CI = [-0.024, -0.013]). The moderating role of forecasted positive affect (PA)/forecasted negative affect (NA) between hyperarousal and life satisfaction was significant (beta = 0.058, CI = [0.035, 0.081]; beta = 0.037, CI = [0.014, 0.06]). The chain mediating effect of hyperarousal and forecasted PA/forecasted NA on the relationship between exposure to COVID-19 and life satisfaction was also significant (Effect = -0.003, CI = [-0.004, -0.002]; Effect = -0.006, CI = [-0.008, -0.004]).Limitations: The cross-sectional design precludes causal inference.Conclusion: Greater exposure to COVID-19 was associated with more severe hyperarousal symptoms, decreased life satisfaction. Forecasted PA and forecasted NA could moderate and mediate the negative impact of hyper -arousal on life satisfaction. The moderating/mediating role of forecasted PA/NA implied that future in-terventions targeting at improving affective forecasting and reducing hyperarousal might be helpful to improve life satisfaction during the post-COVID-19 era.
摘要：
The study analyzed the effect of PTS (post-traumatic symptoms) reaction on the growth of post-traumatic stress disorder (PTSD) during the peak period of COVID-19. It examined the mediation impact on depression and state anxiety and the moderation effects of gender and infection history on the mediating model. Three novel questionnaires were developed, including the post-traumatic stress reaction (PTSR) questionnaire, depression questionnaire, post-traumatic growth (PTG) questionnaire, and the Spielberg State Anxiety Scale (STAI). A total of 16,438 residents in China were investigated during the coronavirus disease 2019. An independent sample t-test was conducted to determine gender and infectious history differences in PTSR, state anxiety, depression, and PTG. Moreover, the Hayes mediation process macro model 4 was applied to examine the mediation impact of depression and state anxiety on PTSD and PTG and the moderation effects of gender and infection history on the mediation model. The study states that state anxiety mediates the relationship involving PTSD symptoms as well as post-traumatic growth (PTG) [2]; depression mediates the relationship involving PTSD symptoms and post-traumatic growth (PTG) [3]; state anxiety and depression have a chain mediating effect between (PTSR) and (PTG) [4]; gender modifies the mediation effect, as does infection history modify the mediation effect. It concludes that post-traumatic stress reaction positively predicted state anxiety, but state anxiety negatively predicted PTSD development. Depression showed a significant positive correlation with PTSR and PTG.

摘要：
INTRODUCTION: Adolescence is a sensitive transitional period accompanied by great physical, mental, and behavioral changes. Therefore, maintaining physical and mental health is crucial to the growth and development of adolescents. As one of the important indicators of mental health, the influencing factors of life satisfaction have been widely concerned by scholars. In recent years, with the rapid development of Internet technology, mobile social media has penetrated into all aspects of adolescents' life, which has a subtle impact on their physical and mental health. Existing studies have indicated that mobile social media use can affect adolescents' life satisfaction. However, little is known about the mediating and moderating mechanisms linking this association. This study developed a moderated mediation model to examine the mediating role of meaning in life and the moderating role of childhood psychological maltreatment. METHODS: A total of 1,198 adolescents across four provinces and municipalities of China completed questionnaires on mobile social media use, life satisfaction, meaning in life, and childhood psychological maltreatment. RESULTS: After controlling for gender and age, the results demonstrated that mobile social media use was positively associated with life satisfaction and meaning in life among adolescents. Moreover, meaning in life fully mediated the association between mobile social media use and life satisfaction. Finally, the association between mobile social media use and life satisfaction, as well as that between mobile social media use and meaning in life, was moderated by childhood psychological maltreatment. Specifically, these associations are stronger for adolescents with high levels of psychological maltreatment. DISCUSSION: These findings shed light on the important mechanism underlying mobile social media use's effects on adolescents' life satisfaction, which is helpful to formulate targeted measures for improving adolescents' life satisfaction.

摘要：
BACKGROUND: As a result of the COVID-19 pandemic and its far-reaching impact, the prevalence of posttraumatic stress disorder (PTSD) symptoms is increasing significantly in China. Yet access to reliable and effective psychological treatment is still limited during the pandemic. The widespread adoption of mobile technologies may provide a new way to address this gap. In this research we will develop an Acceptance and Commitment Therapy (ACT) based intervention delivered by mobile application and will test its usability, efficacy, and mechanism of its effects in relieving PTSD symptoms. METHODS: A total of 147 Chinese participants with a diagnosis of PTSD according to the Clinician Administered PTSD Scale (CAPS-5) will be randomly assigned to an intervention group (app-delivered ACT), an active comparison group (app-delivered mindfulness), or a waitlist group. Participants in the intervention group or comparison group will use their respective apps for one month. Online self-report questionnaires will be used to assess the primary outcome of PTSD symptoms and the secondary outcomes symptoms of depression, symptoms of anxiety, and posttraumatic growth. The potential mediating variable to be tested is psychological flexibility and its components. These assessments will be conducted at baseline, at five times during treatment, at the end of treatment, and at 1- and 3-month follow-ups. DISCUSSION: As far as we know, this study is the first randomized controlled trial to investigate the usability, efficacy, and mechanism of an app-delivered ACT intervention for PTSD. Furthermore, the research will assess the effect of treatment in reducing dropout rates, explore effective therapeutic components, and investigate mechanisms of symptom change, which will be valuable in improving the efficacy and usability of PTSD interventions.Trial registration: ChiCTR2200058408.

摘要：
Evaluating the protein-ligand binding affinity is a substantial part of the computer-aided drug discovery process. Most of the proposed computational methods predict protein-ligand binding affinity using either limited full-length protein 3D structures or simple full-length protein sequences as the input features. Thus, protein-ligand binding affinity prediction remains a fundamental challenge in drug discovery. In this study, we proposed a novel deep learning-based approach, DLSSAffinity, to accurately predict the protein-ligand binding affinity. Unlike the existing methods, DLSSAffinity uses the pocket-ligand structural pairs as the local information to predict short-range direct interactions. Besides, DLSSAffinity also uses the full-length protein sequence and ligand SMILES as the global information to predict long-range indirect interactions. We tested DLSSAffinity on the PDBbind benchmark. The results showed that DLSSAffinity achieves Pearson's R = 0.79, RMSE = 1.40, and SD = 1.35 on the test set. Comparing DLSSAffinity with the existing state-of-the-art deep learning-based binding affinity prediction methods, the DLSSAffinity model outperforms other models. These results demonstrate that combining global sequence and local structure information as the input features of a deep learning model can improve the accuracy of protein-ligand binding affinity prediction.
