摘要：
Post-deduplication in traditional cloud environments primarily focuses on single-node, where delta compression is performed on the same deduplication node located on server side. However, with data explosion, the multi-node post-deduplication, also called global deduplication, has become a hot issue in research communities, which aims to simultaneously execute delta compression on data distributed across all nodes. Simply setting up single-node deduplication systems on multi-node environments would significantly affect storage utilization and incur secondary overhead from file migration. Nevertheless, existing global deduplication solutions suffer from lower data compression ratios and high computational overhead due to their resemblance detection's inherent limitations and overly coarse granularities. Similar blocks typically have high correlations between sub-blocks; inspired by this observation, we propose IBNR (Intra-Block Neighborhood Relationship-Based Resemblance Detection for High-Performance Multi-Node Post-Deduplication), which introduces a novel resemblance detection based on relationships between sub-blocks and determines the ownership of blocks in entry stage to achieve efficient global deduplication. Furthermore, the by-products of IBNR have shown powerful scalability by replacing internal resemblance detection scheme with existing solutions on practical workloads. Experimental results indicate that IBNR outperforms state-of-the-art solutions, achieving an average 1.99× data reduction ratio and varying degrees of improvement across other key metrics.
摘要：
Friend selection is a crucial aspect of social development, particularly during preschool years. This study investigated the role of the liking gap in shaping preschoolers' friend selection mechanisms through two experiments. In Experiment 1 (N = 120), a liking gap task was used to examine whether preschoolers perceive a discrepancy between how much they like familiar friends and how much they believe those friends like them in return. The results indicated that preschoolers tend to assume that their most liked peers evaluate them less positively than they do in return, whereas they believe their least liked peers evaluate them more favorably than expected. In Experiment 2 (N = 117), a friend selection task was conducted to assess whether the liking gap influences preschoolers' choices of friends among unfamiliar peers. The findings revealed that while preschoolers prefer to befriend individuals they like or who like them, their decisions also reflect an awareness of how they are perceived by others. These results suggest that by ages 5 to 6, preschoolers develop an emerging sensitivity to social evaluations, which plays a role in their friend selection process.

摘要：
This study, which is a longitudinal extension of previous cross-sectional studies in Chinese and American college students and general adults (Dixit, He, Whited, Ellis, & Zickgraf, 2023; He, Chen, Wu, Niu, & Fan, 2020; Xu et al., 2024), used latent profile and latent transition analyses to investigate negative emotional eating patterns and the stability of these patterns in 1462 Chinese adolescents (41% boys, aged 11−17 years) at baseline and 18 months later. We also explored baseline demographic predictors of negative emotional eating patterns and the associations between these patterns and outcome variables measured 18 months later. Negative emotional eating was measured with the Adult Eating Behavior Questionnaire (emotional undereating and emotional overeating subscales). Latent profile analysis (LPA) replicated the four patterns of negative emotional eating in each wave of assessment: low emotional eating (Low-EE), emotional overeating (EOE), emotional undereating (EUE), and emotional over- and under-eating (EOE-EUE). Latent transition analysis (LTA) showed that the EE patterns had transition probabilities of <55% remaining in the same class across 18 months. Furthermore, relative to adolescents in the stable Low-EE group, adolescents in all other stable or unstable emotional eating groups in LTA were linked to higher eating disorder psychopathology and psychological distress measured 18 months later. Thus, emotional eating, regardless of type (i.e., EOE, EUE, and EOE-EUE) and stability (i.e., stable or unstable), may be a viable research and treatment target in improving adolescents’ eating behaviors and mental health.

摘要：
OBJECTIVE: The present longitudinal study examined sex-specific, symptom-level relationships among emotion regulation (ER), interpersonal problems (IP), and eating disorder (ED) psychopathology in a large sample of Chinese adolescents. METHOD: Data were from a project with four waves of data collection (N = 1540; 710 boys and 830 girls) at 6-month intervals over 18 months. Questionnaires assessed ED psychopathology, ER, and IP at each wave of data collection. Longitudinal network analyses were conducted separately for boys and girls. Sex differences in the network structures were also examined. RESULTS: The results revealed pronounced heterogeneity in the presentation of ED psychopathology, ER, and IP across Chinese adolescent boys and girls longitudinally and intra-individually. For example, weight/shape preoccupation in ED psychopathology and awareness in ER emerged as important nodes in the temporal network for boys. However, weight/shape preoccupation and dissatisfaction in ED psychopathology were identified as the most important nodes in the temporal network for girls. Regarding bridge strength, awareness in ER emerged as the node with the highest connectivity in the temporal network for boys. At the same time, weight/shape dissatisfaction in ED psychopathology was the node with the highest connectivity for girls. DISCUSSION: The current study extended network theory to better understand the longitudinal interplay among ER, IP, and ED psychopathology in Chinese adolescents and their sex differences in the importance of symptoms. Such insights may pave the way for developing targeted prevention and treatment strategies for adolescent boys and girls in China.

摘要：
Holland’s Realistic, Investigative, Artistic, Social, Enterprising, and Conventional (RIASEC) model has been widely used for career counseling, vocational assessment, and educational choice. However, vocational interest types can be affected by culture, and the fourth industrial revolution has led to the emergence of many new occupations, rendering many occupational titles and work tasks in Holland’s RIASEC model outdated. The present study proposed nine interest types in contemporary China: Artistic (A), Natural (N), Enterprising (E), Conventional (C), Technological (T), Investigative (I), Powerful (P), Social (S), and Operational (O), and developed a vocational interest scale with nine subscales. We generated items by drawing from a literature review, occupational categories, and expert reviews, used exploratory factor analysis (EFA, N = 628, Mage = 12.75 years; 47% girls) to reduce the number of items, and confirmatory factor analysis (CFA, N = 627, Mage = 12.76 years; 48% girls) to validate the factor structure. This study clarified vocational interest types in contemporary China, developed and validated a vocational interest scale for the digital age, and provided a measurement tool for educational choice and career counseling.

摘要：
This study aimed to explore the effectiveness of school-based mindfulness training on learning burnout of Chinese middle school students and the mediating role of psychological resilience between dispositional mindfulness and learning burnout. A cluster randomized controlled trial was conducted with repeated measurement analysis, in which 62 Chinese middle school students in the experimental group received a 10-week school-based mindfulness training. In comparison, 63 students in the control group were randomized to receive no intervention. Learning burnout, dispositional mindfulness, and psychological resilience were measured by Adolescent Student Burnout Inventory, Five Facet Mindfulness Questionnaire, and Resilience Scale for Chinese Adolescents, respectively. The results showed: (1) Compared with the experimental group's pre-test scores and the control group's pretest and posttest scores, the posttest scores of learning burnout in the experimental group significantly decreased. In contrast, the posttest scores of dispositional mindfulness and psychological resilience in the experimental group significantly increased. Meanwhile, the control group gained no significant changes between the pre-and posttest in learning burnout, dispositional mindfulness, and psychological resilience. (2) Dispositional mindfulness was positively related to psychological resilience, while dispositional mindfulness and psychological resilience were negatively associated with learning burnout. (3) The direct effect of dispositional mindfulness on learning burnout and the mediating effect of psychological resilience between dispositional mindfulness and learning burnout were significant. This study suggested that school-based mindfulness training distinctly improves dispositional mindfulness and psychological resilience and alleviates learning burnout in Chinese middle school students. Furthermore, psychological resilience plays a mediating role between dispositional mindfulness and learning burnout.
School-based mindfulness training is an effective intervention method to alleviate learning burnout of Chinese middle school students.
Dispositional mindfulness is a protective factor of learning burnout, and psychological resilience plays a mediating role between dispositional mindfulness and learning burnout.
School-based mindfulness training alleviates learning burnout by improving dispositional mindfulness and psychological resilience.

This study aimed to explore the relationship between life events and non-suicidal self-injury (NSSI) in college students, as well as the mediating effect of sleep disturbances and psychotic-like experiences (PLEs). After excluding invalid questionnaires, 5,754 were retained, and the valid efficiency was 75.94%. The subjects were aged 16 to 29 years (M = 19.166; SD = 1.392), with 1,969 males (34.22%) and 3,785 females (65.78%). Life events, sleep disturbances, PLEs, and NSSI were assessed using standard scales. Data were analyzed by Pearson Correlation Analysis and bias-correction percentile Bootstrap method. The results show that (1) life events were significant positive predictors of NSSI, sleep disturbances, and PLEs; (2) sleep disturbances, PLEs, and the chain mediation between the two, were mediators between life events and NSSI. Life events are thus shown to be an important external factor influencing NSSI in university students, and this process is mediated through sleep disturbances, PLEs, and the chain between the two. Interventions for NSSI can therefore be made by improving college students’ sleep quality and reducing PLEs.

Abstract: This study aimed to explore the effectiveness of mindful self-compassion training (MSCT) on suicidal ideation in rural left-behind children and explore the mediating role of positive psychological capital and social adaptation between trait mindfulness and suicidal ideation, to reveal the potential mechanism of MSCT in suicidal ideation. In this study, 69 rural left-behind children (mean age 13.81 ± 0.77) and 66 non-rural left-behind children (mean age 13.76 ± 0.70) were recruited by the convenience sampling method. Sixty-nine left-behind children were randomly divided into the experimental group (35) and the control group (34). Participants in the experimental group received a ten-week MSCT, while the control group did not receive the experimental intervention. The Positive and Negative Suicide Ideation Inventory (PNSI), Five Facet Mindfulness Questionnaire (FFMQ), Positive Psychological Capital Questionnaire (PPCQ) and Social Adaptation Diagnostic Scale (SADS) were used for psychological evaluation. The results show that: 1) The suicidal ideation level of rural left-behind children was significantly higher than that of non-left-behind children. 2) Trait mindfulness, positive psychological capital and social adaptability were positively correlated with each other, while negatively correlated with suicidal ideation. 3) The total and direct effects of trait mindfulness on suicidal ideation were significant; the mediation, chain and total mediation effects of positive psychological capital and social adaptability between trait mindfulness and suicidal ideation were significant. 4) The results of the intervention experiment showed that compared with the pretest scores of the experimental group and the pre- and post-scores of the control group, the posttest scores of suicidal idea of the experimental group significantly decreased, while the posttest scores of trait mindfulness, positive psychological capital and social adaptability significantly improved. At the same time, there were no significant differences between the two assessment results of the suicidal ideation, trait mindfulness, positive psychological capital, and social adaptability of the control group. This study proves that rural left-behind children are a high-risk group of suicidal ideation, and MSCT is an effective method to intervene in suicidal ideation in rural left-behind children. The chain mediation model of trait mindfulness-positive psychological capital-social adaptability-suicidal ideation partially reveals the mechanism of mindfulnss-based intervention in suicidal ideation.
