Nonparametric regression method for broad sense agreement

Characterising the correspondence between an ordinal measurement and a continuous measurement is often of interest in mental health studies. To this end Peng et al. [(2011), ‘A Framework for Assessing Broad Sense Agreement Between Ordinal and Continuous Measurements’, Journal of the American Statistical Association, 106, 1592–1601] introduced the concept of broad sense agreement (BSA) and developed nonparametric estimation and inference for a BSA measure. In this work, we propose a nonparametric regression framework for BSA, which provides a robust tool to further investigate population heterogeneity in BSA. We develop inferential procedures including regression function estimation and hypothesis testing. Extensive simulation studies demonstrate satisfactory performance of the proposed method. We also apply the new method to a recent Grady Trauma Study and reveal an interesting impact of depression severity on the alignment between a self-reported symptom instrument and clinician diagnosis in posttraumatic stress disorder patients.     

Grandparenting and support from adult children: Does children’s international migration make a difference for Chinese older adults?

ABSTRACT

Guided by social exchange theory, this study investigates the association between grandparenting and support from adult children, and the role of children’s international migration in moderating such association. Data were derived from a 2012 survey of older adults in Beijing, China (478 adult children nested in 300 older parents). The results of independent cluster logistic and linear regressions showed that regardless of children’s migration status, grandparenting was significantly associated with a greater likelihood of receiving household help and personal care, but not with emotional or financial support from children. Children’s migration status moderated the associations between grandparenting and receiving support from children. Theoretical implications for research and practical implications for services and policies are discussed.     

Exposure to news about the South China Sea,nationalism, and government evaluation: examining the mediation roles of third-person effects and online discussion

Based on the communication mediation model, the third-person effect hypothesis was integrated to analyze the influence of the exposure to South China Sea news on its perceived effects on the self and others. In addition, the influences of such exposure on online discussions and political attitudes were examined, specifically in relation to nationalism and government evaluation. The survey (N?=?868) found that the respondents perceived a stronger media effect on others than on themselves, whereas exposure to traditional and news media exposure exhibited equivalent effects on the self and on others. Moreover, the perceived effects on oneself promoted online discussion and nationalism, whereas the perceived effects on others improved government evaluation. The findings of this study indicate that the effects of media exposure on nationalism and government evaluation are marginally mediated by perceived effects, online discussion, or both.     

近现代广东人口迁移的特点(1840-1949)

广东向海外移民自15世纪就已经开始.广东人口的迁移,表现出与以往大不相同的特点:一是大量向海外迁移,这是广东近代人口迁移最主要的流向;二是向邻省迁移,这主要是由灾荒、战乱和破产农民为生活所迫而引起的.近代广东人口的迁移,为移入国家和地区的经济发展和社会进步付出了艰辛的劳动,做出了巨大的贡献.

探寻“中国模式”的发展

＂中国模式＂是发展的模式,它的提出有一定的积极意义,但同时也存在不足。我们要抓住机会,认真研究＂中国模式＂,客观地对待＂中国模式＂,在分析＂中国模式＂的成就和弊端的基础上,重新鉴定＂中国模式＂的实质,并完善和发展＂中国模式＂。     

论激进生态政治的依靠主体——安德鲁·多布森生态政治理论解读

激进生态政治要求彻底改变资本主义制度及其生活方式,以构建自然与社会平衡的绿色社会.此变革的依靠主体为何?英国生态政治学者安德鲁·多布森在其<绿色政治思想>一书中,依此对普世主义、中产阶级、"新社会运动"、"新无产阶级"和女性等几个潜在主体进行了分析,最终得出激进生态政治专注寻求特定依靠主体的必要性和此任务之艰巨性的结论.     

从“选择制”到“普惠制”——城市户籍改革政策取向与路径探析

城市类型、户口"含金量"与户籍改革进展存在一定的逻辑关系,大部分城市仍然存在依"身份"甄别的福利和权益歧视.城市户籍改革必然要进行利益关系的调整,促进流动人口市民化是城市户籍改革的重要环节.户籍改革的最终目标是从"完全的控制体制"回归"登记体制",过渡期内应由"选择型制度"走向"普惠型制度".     

工业化过程中水运的地位及优势

水运是一种最古老的运输方式,其在运输行业的地位与国家经济发展,特别是工业化的程度密切相关。在经济高速增长,工业化蓬勃发展的时期,水运在运输中的地位不仅没有下降,反而上升了。这是因为水运的货物主要是煤炭、石油、矿建材料等原料型物品,而工业化的初期和高峰期是对于这些物品需求最为旺盛的时期。另一方面,水运的成本远低于公路和铁路运输,而且还具有运量大、耗能少、排放少、占地少、安全可靠适应性好等优势。因此,在我国高速工业化的现阶段,大力发展水路运输,既符合社会发展的一般规律,也对于环境保护、节能减排有着巨大的好处。
