Based on this model, the Social Networking Addiction Scale (SNAS) was developed. aim study to test psychometric properties Chinese version SNAS (SNAS-C). <b>Methods:</b> This used sample 3383 university students conduct confirmatory factor analysis (CFA) explore structural validity SNAS-C. examined Pearson correlations between six subscales...

Objective This study aims to explore the association between health information preferences and specific behaviors outcomes, such as preventive measures chronic disease management among college students. It assesses how different levels of preference influence individuals’ utilization, perception, self-efficacy within healthcare contexts. Given rising prevalence non-communicable diseases younger populations in China, this research seeks understand tailored can support effective education...

Background Physical literacy (PL) is an important tool to promote physical activity of individuals, and the level individuals affects their behaviors. Currently, fitness college students in China a prominent issue, assessing among may provide tools directions further precisely intervene behaviors future. This study aimed develop student questionnaire (CSPLQ) address lack currently available assessment for Chinese students. We hoped collect validity evidence this measure self-assessment...

Background/objective Social physique anxiety (SPA) is a prevalent psychological issue among emerging adults, regardless of gender. Many studies have shown that high levels SPA are associated with various negative consequences on both physical and mental well-being. Considering the potential severity SPA’s its prevalence it imperative to investigate factors mechanisms contribute in this population. Although prior identified associations between adulthood, digital media use, young individuals,...

Summary Parallel semi‐implicit method for pressure‐linked equations(SIMPLE) algorithm is used to solve the 3‐D incompressible pipe flow problem. In this paper, we proposed a novel parallel SIMPLE that uses alternate tiling technique. Firstly, based on domain decomposition was established, and implementation of partition data exchange presented. Then, presented serial finite difference stencil tiling. Furthermore, an iteration space two‐way proposed, introducing sequence iterative tiles as...

Green development is an important way to achieve sustainable development. In recent years, it has become one of the main research hotspots. Based on principle DPSIR model, this paper constructed a green evaluation index system including 17 second-level indicators from five first-level indicators, namely driving force indicator, pressure state impact and response used TOPSIS model evaluate Beijing-Tianjin-Hebei region 2010 2020. The results show that :(1) closeness indicator layer generally...

<title>Abstract</title> Due to the high density of ships and complex traffic environment in coastal areas, developing ship trajectory prediction methods is an imperative task for effective collision avoidance. The performance most previous limited by issues regional discrepancy Automatic Identification System (AIS) data singularity feature extraction. To address these two issues, this paper proposes improved framework based on AIS. proposed mainly consists parts: (1) A preprocessing module...

Objective This study aims to evaluate the reliability and validity of Chinese version Physical Activity Social Support Scale (PASSS-C) its measurement invariance across different gender groups in a college student sample. Methods A total 1,689 students participated study. We assessed internal consistency PASSS-C using Cronbach’s alpha McDonald’s omega. Confirmatory Factor Analysis (CFA) was conducted test five-factor model. Multi-group CFA used examine equivalence between male female groups....

Objective The escalating prevalence of physical inactivity among college students represents a significant public health challenge, particularly in light its correlation with detrimental outcomes. A growing body evidence underscores the necessity adhering to recommended levels regular activity thwart onset chronic diseases. One primary aim school education initiatives is elevate and bolster student motivation toward engaging exercise. Engagement sports activities has demonstrated efficacy...

This paper constructs a three-level evaluation index system for the high-quality development of Beijing's economy from six dimensions and evaluates efficiency 2000 to 2019 by using DEA model with non-expected outputs. The main conclusions are as follows: point view efficiency, comprehensive whole shows first decline then an increase, there is little difference in scale which completely close efficiency.

This paper constructs a three-level evaluation index system for the high-quality development of Beijing's economy from six dimensions and measures level 2000 to 2019 by using entropy weight TOPSIS. The main conclusions are as follows: perspective comprehensive measurement level, is constantly improving, but there still certain gap optimal value; 2004, growth rate was slower, with an average annual increase less than 1%; first-level indexes, coordinated maintained at 0.17, open has seen small...
