Dementia Knowledge in Chinese Newspapers (2005-2020): A Topic Modeling Analysis.

How public policies convey dementia is an important source of the public's understanding of dementia, and newspapers are critical to depicting and disseminating this information to the public. The present study used topic modeling strategies to analyze Chinese newspaper portrayals of dementia from 2005 to 2020 to trace changes in key areas of dementia knowledge in relevant policies. Using WiseNews, the largest Chinese media database, we chose 45 newspapers from mainland China and identified 12,719 articles related to dementia. Using latent Dirichlet allocation (LDA), we performed a topic modeling analysis and identified the six most prevalent topics on dementia across articles: lifestyle recommendations, neighborhood life, foundational scientific research, celebrity and media portrayals, dementia caregiving, and pharmaceutical innovations - all related to the dementia knowledge scale's four dimensions. Findings suggest a steady increase in the number of articles on dementia caregiving and a decline in lifestyle recommendations from 2005 to 2020. However, newspapers continued to stigmatize aging by regularly co-depicting dementia and old age and by using biased terminology. Among the first to investigate dementia's portrayals in mainland Chinese newspapers, this study illuminates the need for expanding mass media campaigns to raise the country's dementia knowledge to foster a dementia-inclusive society.

Community social capital, migration status, and Chinese rural children's psychosocial development.

Migration's impact on Chinese rural children's psychosocial development is the subject of growing research attention. While scholars highlight the critical role of social support, they have yet to systematically examine whether and how community social capital, which provides proximal social support for families, affects rural children's psychosocial development as well as whether such associations vary by children's migration status. Using data from the child component of the 2012 Chinese Urbanization and Labor Migration Survey, this article shows that community social capital reduces children's behavioral and emotional problems; however, left-behind children and migrant children gain less from community social capital than children with at-home parents. In addition, left-behind girls fare worse and gain less from community social capital than left-behind boys. Together, these findings imply that community social capital reinforces the disadvantaged psychosocial development of rural children who experience parental migration and evidence the enduring gender inequality in rural China.

Hukou Locality and Intermarriages in Two Chinese Cities: Shanghai and Shenzhen.

China's household registration system (hukou) has created an institutional boundary for the social integration of migrants, but few studies have explored if hukou barriers vary by city. We investigate the value of hukou locality in Shanghai and Shenzhen by comparing their patterns of intermarriage between locals and migrants. We hypothesize that levels of intermarriage reflect the rigidity of the hukou barrier- the likelihood of intermarriage is lower and tradeoffs for local hukou are higher if one city has more stringent hukou policies than the other. Using data from the 2005 mini-census, we find support for our hypothesis. Shanghai, in which internal migrants in China find it most difficult to secure local hukou, exhibits lower levels of intermarriage and lower levels of hukou locality-education exchange between locals and migrants compared to Shenzhen. The findings suggest that the decentralization of China's hukou system and subsequent varying hukou policies have made hukou locality an increasingly salient factor in shaping migrants' integration and social inequality.
