Abstract This study employed a longitudinal approach to investigate how positive feedback and social support mediate the connection between active social network use and feelings of loneliness. A total of 811 college students (females = 58.20%, M_age = 19.15, SD = 0.99) participated in this research study. At T1 time point, students completed the Active SNS Questionnaire. At T2 time point, students completed the online versions of the Positive Feedback Scale, Perceived Social Support Multidimensional Scale, and UCLA Loneliness Scale. T2 online positive feedback influences how T1 actively uses their social network, which relates to T2 loneliness, More >

Abstract Background: Depression represents a significant global mental health burden, particularly among middle-aged and older Chinese with chronic diseases in high-altitude regions, where harsh environmental conditions and limited social support exacerbate mental health disparities. This paper aims to develop an interpretable machine learning prediction framework to identify the key factors of depression in this vulnerable population, thereby proposing targeted intervention measures. Methods: Utilizing data from the China Health and Retirement Longitudinal Study in 2020, this paper screened out and analyzed 2431 samples. Subsequently, Recursive Feature Elimination and Least Absolute Shrinkage and Selection Operator were applied to screen… More >

Abstract To explore and evaluate the longitudinal utilization degree of marine shale gas horizontal wells in southern Sichuan Basin (hereinafter referred to as “southern Sichuan”), focusing on the shale of Wufeng formation-Longyi1 sub-member in the deep Z block. By using the data from core experiments, well logging, and fracture height detection, a systematic analysis from the perspectives of reservoir distribution, longitudinal utilization height of hydraulic fractures, and longitudinal utilization degree of horizontal wells was conducted. The research results show that: (1) The overall reservoir conditions of the Wufeng formation-Longyi1 sub-member in the study area are relatively… More > Graphic Abstract

Abstract The impact of longitudinal stiffener configurations on the structural performance of orthotropic steel bridge decks (OSD) was systematically investigated, with emphasis on U-shaped, T-shaped, and rectangular ribs. Finite element analysis was employed to evaluate deformation and stress distribution under three critical loading scenarios: vertical uniform load, vertical eccentric load, and lateral uniform load. Equivalent models ensuring identical steel usage, moment of inertia, and centroid alignment were established to compare five stiffener configurations. Results demonstrate that U-rib configurations exhibit superior performance in controlling local displacements and minimizing stress concentrations. Under eccentric loading, U-ribs significantly reduce deck… More >

Abstract This longitudinal study examined the association between parental autonomy support and school-aged children’s adjustment across four major domains of school functioning, as well as the mediating role of children’s executive function. Participants were 476 school-aged children (girl: 49.2%, M_age = 10.49 years, SD = 1.32 years), who completed the Psychological Autonomy Support Scale, the Behavior Rating Inventory of Executive Function–2, and the Primary School Students’ Psychological Suzhi Scale at baseline and at two subsequent follow-up assessments. Results from unconditional latent growth curve models and structural equation modeling indicated that paternal autonomy support was a significant predictor… More >

Abstract Objectives: Positive family functioning (FF) is critical for adolescent development, yet only a few studies have examined this developmental trajectory pathway. This study aimed to identify different types of FF development trajectories during junior high school students, investigate their influence on social avoidance (SA), and further examine the mediating role of preference for solitude (PS) between them. Methods: A three-wave longitudinal study was used with six-month intervals. Questionnaire data were collected from 436 junior high school students in Jiangxi Province, China. Participants ranged in age from 11 to 14 years old (Mean = 12.89 years,… More >

Abstract The girder end restraint devices such as bearings and dampers on long span suspension bridge will deteriorate over time. However, it is difficult to achieve the quantitative assessment of the performance of the restraint device through existing detection methods in actual inspections, making it difficult to obtain the impact of changes in the performance of the restraint device on the bridge structure. In this paper, a random vehicle load model is firstly established based on the WIM data of Jiangyin Bridge, and the displacement of girder end under the actual traffic flow is simulated by… More >

Abstract Objectives: Few studies have investigated longitudinal associations of loneliness with health outcomes in Africa. This study aimed to assess the longitudinal associations between loneliness and mental and physical health among aging adults in South Africa. Methods: Data from the 7-year longitudinal Health and Ageing in Africa (HAALSI) study conducted in South Africa were used in the analysis (analytic sample: n = 3707, aged 40 years and older). Loneliness was measured with one question. Longitudinal relationships between loneliness and each health outcome were estimated using Generalized Estimating Equations analysis (GEE), hazard ratios (HRs) (95% CI) were used… More >

Abstract Background: With the rapid growth of internet usage, adolescent cyberbullying has become a pressing issue. This study examines the longitudinal impact of leisure-time physical activity and peer relationships on cyberbullying over a one-year period, drawing on the Stage-Environment Fit Theory and the Interpersonal Relationship Theory. Methods: A three-wave longitudinal study was conducted over one year, involving 896 middle school students from five schools in Sichuan, Jiangsu, and Guangdong, China, selected to ensure regional diversity. Participants were recruited using stratified random sampling, and data were collected at four-month intervals. Leisure-time physical activity, peer relationships, and cyberbullying… More >

Abstract This longitudinal study investigated how self-management and learning burnout influences the relationship between habitual mobile phone use and subjective well-being among first-year university students. A sample of 1172 Chinese university students participated in a two-wave survey, with data collected six months apart at two time points (T1, T2). The results of Pearson correlation revealed that higher habitual mobile phone use at T1 was associated with lower subjective well-being at T2. Self-management was associated with healthy phone use habits and higher subjective wellbeing. Learning burnout risk was higher with habitual phone usage. Lower self-management and learning More >
