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:
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:
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:
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.

摘要:
<jats:p>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.</jats:p>
摘要:
OBJECTIVES: Previous research suggests potential moderating roles of dispositional mindfulness and body image flexibility in the association between body dissatisfaction and disordered eating. However, relevant research is mainly conducted on adult women from Western countries, and limited evidence exists for adolescent samples, especially from non-Western contexts (e.g., China). Thus, this study aimed to examine the moderating roles of dispositional mindfulness and body image flexibility in the relationship between body dissatisfaction and disordered eating in Chinese adolescents. METHOD: We recruited 545 Chinese adolescents (53.9% boys, aged 12-16 years) who completed measures of body dissatisfaction, dispositional mindfulness, body image flexibility, and disordered eating. Moderation analyses were examined with PROCESS macro on SPSS. RESULTS: In separate models, both higher dispositional mindfulness and body image flexibility weakened relationships between body dissatisfaction and disordered eating. However, when both dispositional mindfulness and body image flexibility were entered into the same moderation model, only body image flexibility showed a significant moderating effect. DISCUSSION: Both dispositional mindfulness and body image flexibility may weakenthe association between body dissatisfaction and disordered eating in adolescents. However, body image flexibility might have a stronger effect than dispositional mindfulness. These findings suggest that interventions aimed at reducing body dissatisfaction to prevent disordered eating in adolescents may pay more attention to adolescents' body image flexibility.

摘要:
Abstract: Objective: This study, which adopted loneliness as the variable mediator, aimed to explore the relationship between the self-esteem of junior high school students and the psychological control of their parents. Methods: This study used a convenient sampling method, selecting a total of 524 junior high school students from Siyuan Experimental School in Chenxi County, Huaihua, and Mayangshui county middle school in Lufeng Town, Xupu County, Huaihua, who filled in “Self-Esteem Scale (SES)”, “Children Loneliness Scale (CLS)” and “Parental Psychological Control Scale”. Results: 1) The overall level of parental psychological control of middle school students is moderately high, while the overall level of self-esteem and loneliness is moderately low. 2) According to the research, the level of parental psychological control is negatively correlated with self-esteem (r = −0.537, p < 0.001); 3) According to the research, the level of parental psychological control was positively correlated with a sense of loneliness. (r = 0.138, p < 0.001); 4) There was a negative correlation between parental psychological control and loneliness (r = −0.584, p < 0.001); 5) The mediating effect of loneliness was certainly of the essence. Conclusion: 1) The higher the level of parental psychological control, the lower the level of self-esteem of junior high school students. Besides, their level of loneliness would increase with the raised control level; 2) The higher level of loneliness is accompanied by a lower level of self-esteem; 3) Loneliness played a mediating role in the relationship between parental psychological control and the self-esteem of junior high school students.
摘要:
Body image flexibility has shown robust negative associations with body dissatisfaction. However, research in this area is confined to cross-sectional studies on adults in Western cultural contexts. Responding to these gaps and the unique cultural nuances and increasing prevalence estimates of body dissatisfaction in China, we examined the bi-directional nature of body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescent boys and girls (N = 1381, 57.3 % girls) at two points over 18 months (Wave [W] 1=baseline, W2=18 months later). We also explored sex differences in longitudinal models. In boys, higher W1 body image flexibility was associated with lower W2 body fat dissatisfaction, and higher W1 body fat dissatisfaction was associated with lower W2 body image flexibility. Null prospective associations between body image flexibility and muscularity dissatisfaction were identified in boys. In girls, higher W1 body fat and muscularity body dissatisfaction were associated with lower W2 body image flexibility. Higher W1 body image flexibility was associated with lower W2 body fat and muscularity dissatisfaction in girls. We found no significant sex differences in the models. Findings advance a multicultural understanding of the temporal and bi-directional links between body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescents.
