Robust modal estimation and variable selection for single-index varying-coefficient models

In this article, we present a new efficient iteration estimation approach based on local modal regression for single-index varying-coefficient models. The resulted estimators are shown to be robust with regardless of outliers and error distributions. The asymptotic properties of the estimators are established under some regularity conditions and a practical modified EM algorithm is proposed for the new method. Moreover, to achieve sparse estimator when there exists irrelevant variables in the index parameters, a variable selection procedure based on SCAD penalty is developed to select significant parametric covariates and the well-known oracle properties are also derived. Finally, some numerical examples with various distributed errors and a real data analysis are conducted to illustrate the validity and feasibility of our proposed method.     

An Adaptive Functional Autoregressive Forecast Model to Predict Electricity Price Curves

We propose an adaptive functional autoregressive (AFAR) forecast model to predict electricity price curves. With time-varying operators, the AFAR model can be safely used in both stationary and nonstationary situations. A closed-form maximum likelihood (ML) estimator is derived under stationarity. The result is further extended for nonstationarity, where the time-dependent operators are adaptively estimated under local homogeneity. We provide theoretical results of the ML estimator and the adaptive estimator. Simulation study illustrates nice finite sample performance of the AFAR modeling. The AFAR model also exhibits a superior accuracy in the forecast exercise of the California electricity daily price curves compared to several alternatives.

以红色文化推进马克思主义大众化的基本路径探析

推广红色文化是推进马克思主义大众化的重要隐性教育方式,当前以红色文化推进马克思主义大众化,需要进一步加大红色文化资源的宣传营销力度,不断提高其马克思主义大众化载体的现实影响力;努力建立红色文化精神产品体系,不断强化马克思主义理论的市场渗透力和感染力;着力开发红色旅游资源,不断增强大众对马克思主义理论的体验性认同。     

文化融合视域下《红楼梦》的英译

当今文化融合的国际大趋势使翻译与文化的关系变得更为密切 ,文学作品作为民族文化重要载体 ,翻译过程中尽最大可能的异化手法 ,有利于文化的传播 ;而语言由于其在形式上相对稳定的特点 ,合理的归化将更有助于翻译作品为译语读者所接受。在这种需求下 ,《红楼梦》的两个英文译本都做出了一定努力 ,但在满足跨文化交流方面还有待于进一步提高。     

情以物迁诗以"兴"言——论中西诗歌视域中的"兴"

指出中国诗歌独特的魅力集中体现为对“兴”的重视,认为“兴”反应了中国古典诗歌独特而深邃的诗性思维与美学原则,以及一个古朴民族诗意栖居的特质;并以现代西方文学理论视角重新梳理“兴”这一独特而复杂的中国诗学概念,以此比较中西诗歌在表现方法和文化上的深层差异。
