Quantile regression for large-scale data via sparse exponential transform method

In recent decades, quantile regression has received much more attention from academics and practitioners. However, most of existing computational algorithms are only effective for small or moderate size problems. They cannot solve quantile regression with large-scale data reliably and efficiently. To this end, we propose a new algorithm to implement quantile regression on large-scale data using the sparse exponential transform (SET) method. This algorithm mainly constructs a well-conditioned basis and a sampling matrix to reduce the number of observations. It then solves a quantile regression problem on this reduced matrix and obtains an approximate solution. Through simulation studies and empirical analysis of a 5% sample of the US 2000 Census data, we demonstrate efficiency of the SET-based algorithm. Numerical results indicate that our new algorithm is effective in terms of computation time and performs well for large-scale quantile regression.     

Instrumental variable based variable selection for generalized linear models with endogenous covariates

We study the variable selection problem for a class of generalized linear models with endogenous covariates. Based on the instrumental variable adjustment technology and the smooth-threshold estimating equation (SEE) method, we propose an instrumental variable based variable selection procedure. The proposed variable selection method can attenuate the effect of endogeneity in covariates, and is easy for application in practice. Some theoretical results are also derived such as the consistency of the proposed variable selection procedure and the convergence rate of the resulting estimator. Further, some simulation studies and a real data analysis are conducted to evaluate the performance of the proposed method, and simulation results show that the proposed method is workable.     

Policies for Recruiting Talented Professionals from the Diaspora: India and China Compared

Despite the continuous asymmetrical power relations between the Global North and South, the “global race for talent” is no longer a privilege enjoyed only by developed countries. Comparative analysis of policy content and effectiveness has attracted increasing interest. The examination of policy initiatives resulting in return migration of highly‐skilled migrants from the Global North to the Global South, however, remains inadequate. In this article, we provide a comparative analysis of policies targeting high‐level Chinese and Indian professionals including full‐time returnees. Two key differences in policy instruments and outcomes in the two countries are identified and they have implications for migration policies in other countries in the Global South and North.     

农民工参与城镇医疗保障的行为研究

文章利用农民工调查数据,研究了农民工参与城镇医疗保障的影响因素以及城镇医疗保障对农民工医疗支出决策和医疗费用的影响,考察城镇医疗保障制度是否解决了农民工的医疗保障问题。研究结果发现,自评健康状况很好和很不好的农民工都不愿意参与城镇医疗保障,城镇医疗保障既存在逆向选择,也没有有效分散农民工的医疗风险。农民工是否有医疗支出和医疗费用的多少主要取决于疾病严重程度,农民工参与城镇医疗保障对此没有显著性影响。因此,现行农民工城镇医疗保障制度还没有起到为农民工提供足够的医疗保障作用。     

西夏文《经史杂抄》考源

西夏文《经史杂抄》一书出土已近百年,因首尾皆佚,内容芜杂,此前一直未获全文解读,出处亦不明。本文指出此书主要依据敦煌汉文文献《新集文词九经抄》编译而来,是目前所知西夏人编译的唯一一本通篇征引汉文俗文学的作品。对它的解读可以解决夏译汉籍悬而未决的最后一个谜团,从而为研究西夏教育和文化交流提供一份宝贵的材料。     

中国古典诗学范畴的人本构建

从发生学角度看,中国古代诗学范畴体系可分为"物本"与"人本"两大系统,二者根源于中国古代哲学的本体二元论。两汉魏晋时期,随着人物品鉴风气的盛行,人之美学成为流行的美学风尚,于是诗学范畴体系的构建逐渐褪去物本哲学的色彩,更多地展示出人本哲学的特征。古典诗学范畴的人本构建模式,主要围绕着人的形体、感官和精神三大类属展开,形成了一系列互相包容、前后联结并具有丰富内涵意蕴和外延价值的范畴序列。这种建立在人体"小宇宙"基础上去体验、比拟、推论、演化自然大宇宙的思维模式,不仅使得诗学审美范畴的建立具有家族性、连绵性和表现性,也确立了中国诗歌传统中博大深邃的象征思维和诗性智慧。     

论汉语诗歌语言的音乐性(上)——新诗音律研究

这篇长文写于1980年夏秋季,即23岁时,当时我在成都大学中文系的学习即将结束。此文后来一直放在那里,未刊。时隔三十多年,今天看来,这篇东西还是有其意义的:旧体诗词的格律被打破以后,汉语诗歌的音乐性传统如何在新诗中重新得到发扬?这远不仅仅是关乎诗歌的问题,也不仅仅是关乎汉语的问题,而且是关乎民族文化传统的现代转化问题。如果我们今天已经不能"原教旨主义"式地照搬中国古代文化的某些具体形式,那么,我们的民族文化传统精神如何才能得到弘扬?本文对汉语诗歌的音乐性及其在现代新诗中的体现形式的探索,可以说是为这方面的探索提供了一个具体例证。现在把它整理出来,一仍其旧,以存原貌;只是加上了全文的副标题"新诗音律研究"及各节的小标题。     

品牌拓展新市场过程中消费者选择行为研究

研究消费者品牌选择行为是进行品牌拓展新市场的前提。本文基于消费者决策理论,利用元胞自动机分析了品牌文化、广告宣传、邻居关系及数量、竞争者、市场的经济环境等对消费者进行品牌选择时的影响,研究结果表明该模型能较好地模拟出品牌进行拓展新市场过程中的消费者选择行为。通过对品牌拓展新市场过程中的消费者选择行为的分析,找出更适合进行品牌扩张的区域。
