作为南方道德想像历史的《喧哗与骚动》

福克纳在《喧哗与骚动》中建构了美国南方的道德想像的历史,以建构的载体为标准,可以将之分为三个层面,即意象、南方神话与历史观,从而可看出基于不同的层面所建构的对于社会历史的解释,也即三种道德想像的历史:昆丁的过去与现在的共存及对现在的压迫;旧南方的辩护型的自我安慰;和福克纳的痛苦中的批判反思。与此同时文本中也将三种自我身份的建构呈现出来,即昆丁的他我、旧南方的美化的想象的自我、和福克纳的批判反思的自我。     

农民工子女留守原因分析

农民工子女留守农村是国家现行城乡分割的二元体制的结果,也是城乡两种不同社会与文明推拉合力作用的产物,同时是作为父母的农民工在迁移流动中的理性抉择与意识建构。城市生存境遇、乡村归属意识及城乡分割的义务教育体制等是农民工子女留守的重要因素。解决农民工子女问题,需要城乡相关体制的建立。     

Ethnic differences in neighbourly relations in urban China

Using data collected in Lanzhou, this paper examines the effect of minority ethnicity on neighbourly relations in China. It shows that the Hui as a whole express a higher level of satisfaction at relations with neighbours than the Han do. It also shows that the Hui advantage is removed with key background characteristics controlled. Finally, this paper shows intra-group variation among the Hui. These findings suggest that social status is a better predictor of neighbourly relations than the focus on inter-group contrast in traditionality in the existing scholarship of the Hui. Both inter- and intra-group variation in urban life must be examined to attain a more balanced picture of Hui Muslims in China.

Generalized phase I-II designs to increase long term therapeutic success rate

Designs for early phase dose finding clinical trials typically are either phase I based on toxicity, or phase I-II based on toxicity and efficacy. These designs rely on the implicit assumption that the dose of an experimental agent chosen using these short-term outcomes will maximize the agent's long-term therapeutic success rate. In many clinical settings, this assumption is not true. A dose selected in an early phase oncology trial may give suboptimal progression-free survival or overall survival time, often due to a high rate of relapse following response. To address this problem, a new family of Bayesian generalized phase I-II designs is proposed. First, a conventional phase I-II design based on short-term outcomes is used to identify a set of candidate doses, rather than selecting one dose. Additional patients then are randomized among the candidates, patients are followed for a predefined longer time period, and a final dose is selected to maximize the long-term therapeutic success rate, defined in terms of duration of response. Dose-specific sample sizes in the randomization are determined adaptively to obtain a desired level of selection reliability. The design was motivated by a phase I-II trial to find an optimal dose of natural killer cells as targeted immunotherapy for recurrent or treatment-resistant B-cell hematologic malignancies. A simulation study shows that, under a range of scenarios in the context of this trial, the proposed design has much better performance than two conventional phase I-II designs.     

住房攀比与居民消费

本文基于CFPS微观跟踪调查数据,从地位寻求角度分析了住房攀比行为对城镇家庭消费的影响。结果表明：①家庭对自身社会地位等级的主观评价与住房面积、消费水平、户主学历等因素呈显著的正相关关系;②住房面积攀比对城镇家庭消费有明显的抑制作用;③社会地位高的家庭的消费行为对其它家庭的示范效应显著,即中国城镇家庭存在向上攀比的地位寻求动机。     

收入风险、金融教育与家庭金融市场参与

运用中国城市居民消费金融调查数据,基于因果推断的分析框架,采用倾向分值匹配法研究了收入风险、金融教育对家庭金融市场参与的影响。研究发现,收入越稳定,家庭开展金融教育的概率越高;金融教育显著提高了家庭的金融市场参与;按收入风险将样本分组后,上述结论依然稳健,且金融教育对不同家庭金融市场参与的影响具有非对称性。在对家庭收入稳定性分类的基础上,有针对性地增加金融教育的供给,提升家庭整体的金融教育水平,有利于提高家庭金融市场参与度,优化家庭金融资产配置,进而改善家庭金融福利。     

政治哲学的“规定”及其当代性

与“什么是哲学”的答案始终悬而未决一样,“什么是政治哲学”这个问题也为学界争论多年而从未有过“公论”。可以明确的是,尽管政治哲学是具有深远历史传统和丰厚思想资源的研究领域,但将这种研究领域命名为政治哲学却是现代学科构建过程中的晚近事件。以现代政治的现实视角对古典政治哲学的回顾和归纳大致界定了政治哲学的本性、研究对象与致思方式,也在古典与现代的贯通中明晰了政治哲学的当代性。可以说,
