Co-developmental trajectories of psychological need satisfactions at school: Relations to mental health and academic functioning in Chinese elementary school students     

《Learning and Instruction》2021

This study explored the co-developmental trajectories of autonomy, competence and relatedness need satisfactions at school and their relations to mental health and academic functioning in Chinese elementary school students. An accelerated longitudinal design was used with a sample of three cohorts (grade 3, grade 4, and grade 5) (N = 1070, 45.8% female; M_age = 9.44, SD = 0.97) on four occasions at 6-month intervals. Parallel process latent class growth models revealed five heterogeneous patterns (i.e., Congruent-moderate; Congruent-high; Congruent-low; Congruent-decreasing; Low-autonomy, High-competence and relatedness), all of which significantly associated with time-varying mental health and academic functioning indicators. The findings highlight the importance of subgroup differences and possible cultural considerations in understanding the progression of psychological need satisfactions and the need for universal screening and dynamic monitoring of students’ psychological need satisfactions at school and implementing more sophisticated interventions tailored to the unique characteristics of the relevant subgroups to promote optimal mental health and learning.  相似文献   

Business Intelligence Capabilities and Firm Performance: A Study in China     

《International Journal of Information Management》2021

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.  相似文献   

中国大陆侨资与外资发展比较研究——基于2005——2008数据分析     

龙大为  谭天星 《云南师范大学学报(哲学社会科学版)》2011,43(4):84-90

对近年来中国FDI数据与国侨办侨资企业数据库进行全面比较和深入研究发现,近年来的中国侨资企业发展大大超过外资成长:新批侨资企业数量连续大幅度增加且大大超过外资成长;新增侨资在全国FDI中的比重逐年提高;侨资企业平均投资额大增,并且在制造业中比重下降;新批侨资企业主要来源地分布较广,位次变化显著.这一转变根本的原因在于,大多数侨资企业在一二十年的中国经济高速快车上不断壮大,经营规模与产业层次得到提升,与世界企业的差距大大缩小,国际竞争力日益增强。这一重大转变在这次研究中首次被揭示,应引起有关部门的重视。政策取向必须随着新的形势变化应适时调整,高度重视侨资企业的发展。  相似文献

An exploratory study of inter-relationships of acculturative stressors among Chinese students from six European union (EU) countries     

《Int J Intercult Relat》2016

This study examined the inter-relationships of acculturative stressors experienced by Chinese international students. A sample of 463 Chinese students in six EU countries (UK, Germany, France, Netherlands, Spain and Belgium) responded to a web-based survey. The results showed that Chinese students in France suffered from bigger constraints in linguistic issues and dealing with life tasks than Chinese students in UK. Structural equation modeling (SEM) analysis revealed that language constraints and perceived cultural differences play a key role in influencing other stressors. The findings indicated that language constraints and perceived cultural differences accounted for 62% of the total variance of academic integration difficulty; language constraints accounted for 17% of the variance of problems in dealing with daily tasks; perceived cultural differences accounted for 56% of the variance of social integration difficulty; academic integration and problems in dealing with daily tasks explained 14% of the variance of homesickness.  相似文献

The construction of women’s social spaces through physical exercise in urban China     

Huan Xiong 《Sport in Society》2019,22(8):1415-1432

Abstract

By applying feminist geographical theories and qualitative research methods, this article reveals Chinese women’s exercise experiences in urban spaces and discusses how women, through physical activity in neighbourhoods, public places and commercial facilities, constructed social spaces of their own. The findings show that exercise spaces are potentially sites for women’s health, well-being, social networking and collective empowerment. They challenge traditional gendered urban spaces by deconstructing the dual structure of ‘public’ and ‘private’ spheres, inducing women to gradually shift from the ‘edge’ to the ‘centre’. Though the spatial differences in women’s physical activities reflect the diversity and dynamics of women’s spatialities, they also imply the continuous social powers on women in exercise fields, where gendered disparities and class stratification may be sustained.  相似文献
