Background:Cognitive function is a current research hotspot,residence may be related to differences in cognitive function,and the mediating role of leisure activities are limited in Chinese *** study used leisure activities as a mediating variable to investigate the mediating role of leisure activity between place of residence(city-town-rural)and cognitive function among Chinese older,this is where the innovation of the article comes ***:Using cross-sectional data from the 2018 Chinese Longitudinal Healthy Longevity Survey,Pearson correlation analyses were employed to examine the relationships among various *** analyses were conducted using the SPSS PROCESS macro program,version 3.5,written by Hayes,to explore the mediating effects of leisure activity between place of residence and cognitive function in older ***:A total of 10955 older adults were included in this study,with a mean age of(84.23±11.57)*** them,2739(24.8%)lived in the city,3627(33.1%)in town,and 4615(42.1%)in rural areas;their leisure activity score was(5.34±3.77),and their cognitive function score was(24.69±6.65).Place of residence,leisure activities,and cognitive function were significantly correlated(P<0.01).Using city as a reference,place of residence is negatively associated with cognitive function,and place of residence not only had a direct effect on cognitive function in older adults:town-cognitive function(effect=–0.399;95%confidence interval(CI)=(–0.685,–0.113));rural-cognitive function(effect=–0.42;95%CI=(–0.698,–0.141)).There were also indirect effects on cognitive function through the pathway of leisure activity:town-leisure activity-cognitive function(effect=–0.17;95%CI=(–0.246,–0.1)),rural-leisure activity-cognitive function(effect=–0.199;95%CI=(–0.272,–0.13)).Conclusion:Leisure activities play a partially mediating role between the impact of place of residence and cognitive function in Chinese older adults,and it is vital to pay atte

口述历史的差异性是当代公众历史建构中的一个关键问题。百年记忆,当事人回忆的可信度相对较高,相关人的口述也有一定的史料价值。中心与边缘、上层与下层,人所处位置的不同决定了所获信息、记忆建构的不同,也决定了不同个体口述史料的... 详细信息

口述历史的差异性是当代公众历史建构中的一个关键问题。百年记忆,当事人回忆的可信度相对较高,相关人的口述也有一定的史料价值。中心与边缘、上层与下层,人所处位置的不同决定了所获信息、记忆建构的不同,也决定了不同个体口述史料的相异。综合来看,视野不同会让人有不同的认知,从而对事件因果甚至性质有不同的解释。考察建岙红色口述故事采集的采编实践,可对这些问题有更深入的认知。

目前,学界对《克拉拉与太阳》的讨论主要集中在机器人叙事、科技伦理、医学人文学等角度的文学阐释,而对小说的视觉元素和审美来源关注较少。本文将从语象叙事的视角出发,探讨绘画手段在该小说视觉图景建构中的运用,包括立体主义风格的“碎片化”构图、霍普式人物形象再现以及光影的隐喻性表达。视觉艺术形态不仅丰富了小说的审美意趣和艺术表现力,还承载了石黑一雄对科技时代人类生存境遇和精神生活的现实关切。
