A note on LeCam’s bound for the distance between the Poisson binomial and the Poisson distribution

n possibly different success probabilities p ₁, p ₂, ..., p _n is frequently approximated by a Poisson distribution with parameter λ = p ₁ + p ₂ + ... + p _n . LeCam's bound p ² ₁ + p ² ₂ + ... + p _n ² for the total variation distance between both distributions is particularly useful provided the success probabilities are small. The paper presents an improved version of LeCam's bound if a generalized d-dimensional Poisson binomial distribution is to be approximated by a compound Poisson distribution.

浅谈地市党报楼盘广告话语的人文性

以地市党报自身所具有的较大权威性为研究起点,以其发布的楼盘广告作为研究对象,结合地市党报上所刊登的具体楼盘实例,对楼盘广告话语进行深入剖析。认为当前的地市党报楼盘广告注重以人为本铸造品牌,注重“硬件”人性化和“软件”个性化的转化,其广告话语体现了平民视角和人文关怀,具有鲜明的人文性色彩。     

Two point priors and Γ-minimax estimating in families of uniform distributions

It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions, a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax. The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified subintervals of the parameter space if a two point prior is least favourable in Γ.     

关联理论视角下的隐喻翻译研究——以《抗击新冠肺炎疫情的中国行动》英译为例

借助Pragglejaz团队的“隐喻识别程序”对《抗击新冠肺炎疫情的中国行动》白皮书中的隐喻进行分类描述,从认知关联视角切入对各类隐喻翻译进行案例分析。为实现白皮书类外宣文本国际传播的最佳社会效益,最大语境效果、共同的语境假设以及交际传播的目的是译者在实现隐喻跨语际转换时的重要考量准则。     

《春秋》的"大义"与"微言"

春秋时代,诸侯争霸,“霸”即“伯”,即争当“诸侯长”。历史上,虽有孟子等儒者对春秋史事评价过低,但孔子作《春秋》记载春秋大事,对齐桓公、晋文公主盟之事给予了积极、正面的评价,并从这段历史中发现政治智慧与思想之光,以“大义”和“微言”形式总结其中的经验。“大义”主要有：“尊王”“尊周”,反分裂;“选贤与能”,天下为公;天下治理,“会盟”共商;倡仁道,鄙诈力等。“微言”主要有：“大一统”;“通三统”;“张三世”;新“夷夏”观等。《春秋》“大义”和“微言”都具有与时俱进的特质和价值,可以进行现代性阐发与转化：政治上,维护国家统一,反对国家分裂,推举贤能理政;文化上,促进文明交流与民族融合,维护文明延续发展与民族团结等,这些在当代都具有宝贵的借鉴意义。

Retirement patterns in Hong Kong: a censored regression analysis

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model is used to infer the retirement age from people‘s current retirement status and their current age. This model is equivalent to a restricted probit model, and the interpretation of parameters is straightforward. The results clearly show a negative income effect on the retirement decision. The retirement age seems to be positively related to lifetime earnings but negatively related to the rate of decline of earnings with age.
