The estimation of treatment effect for the censored bivariate data under the univariate censoring

This paper establishes a nonparametric estimator for the treatment effect on censored bivariate data under unvariate censoring. This proposed estimator is based on the one from Lin and Ying(1993)'s nonparametric bivariate survival function estimator, which is itself a generalized version of Park and Park(1995)' quantile estimator. A Bahadur type representation of quantile functions were obtained from the marginal survival distribution estimator of Lin and Ying' model. The asymptotic property of this estimator is shown below and the simulation studies are also given     

The measurement of capital utilisation rates

A strategy using spline function interpolation is developed f o r estimating capital utilisation rates . Cobb-Douglas, CES and translog functional forms are used in estimation. Tests for functional forms are conducted leading t o t h e s e l e c t i o n of the Cobb-Douglas form. Quarterly series of estimated utilisation rates and excess capacity measures are presented.

Predicting infectious disease outbreak risk via migratory waterfowl vectors

The spread of an emerging infectious disease is a major public health threat. Given the uncertainties associated with vector-borne diseases, in terms of vector dynamics and disease transmission, it is critical to develop statistical models that address how and when such an infectious disease could spread throughout a region such as the USA. This paper considers a spatio-temporal statistical model for how an infectious disease could be carried into the USA by migratory waterfowl vectors during their seasonal migration and, ultimately, the risk of transmission of such a disease to domestic fowl. Modeling spatio-temporal data of this type is inherently difficult given the uncertainty associated with observations, complexity of the dynamics, high dimensionality of the underlying process, and the presence of excessive zeros. In particular, the spatio-temporal dynamics of the waterfowl migration are developed by way of a two-tiered functional temporal and spatial dimension reduction procedure that captures spatial and seasonal trends, as well as regional dynamics. Furthermore, the model relates the migration to a population of poultry farms that are known to be susceptible to such diseases, and is one of the possible avenues toward transmission to domestic poultry and humans. The result is a predictive distribution of those counties containing poultry farms that are at the greatest risk of having the infectious disease infiltrate their flocks assuming that the migratory population was infected. The model naturally fits into the hierarchical Bayesian framework.     

人大常委会决定重大建设项目问题探讨

重大建设项目是重大事项的内容之一，应当由人大及常委会作出决定。实践中，由人大常委会决定的重大建设项目是非常少的。其原因在于人大常委会与政府之间的关系没理顺。人大常委会与政府对重大建设项目均有决定权。现从二者决定权的性质、行使的侧重点不同探讨人大常委会如何决定重大建设项目问题。

中华文化教育与课程教学的有机结合——以英语专业课程为例

中华文化教育与课程教学的有机结合,是学校实施中华文化教育的重要途径.尽管不同课程和专业有着不同的教学内容与特点,但培养具有良好综合素质人才的教育目标,是各课程教学与中华文化教育结合的共同出发点与归宿.由于学科间的差异,中华文化教育与不同课程相结合的意义不同,结合的基础也不尽相同.英语专业课程的人才培养目标和当前所存在的问题,使其与中华文化教育的结合具有特殊的意义;英语专业课程的文化属性为两者的结合提供了基础;观念的更新、中华文化教育在课程教学中的明确定位、教育者素养的提高等,是两者结合的基本保障.     

可行能力与农民工的福利状况评价

基于辽宁省沈阳市农民工调查数据,应用森的可行能力理论和模糊数学方法对农民工的福利状况进行整体评价。结果发现,农民工福利水平的总模糊指数为0.365,处于较低水平。分指标看,健康状况方面的福利状况处于较高水平,居住环境和精神感受方面的福利状况处于中间水平,其它功能性指标的福利水平较低。在影响农民工福利的主要因素中,工作环境和防护性保障的改善对提升农民工福利影响最大。运用OLS回归模型对农民工的福利状况进行扩展分析,发现农民工群体内部存在较强的异质性,并且不同特征的农民工群体福利水平相差很大。     

Imposing and Testing for Shape Restrictions in Flexible Parametric Models

In many economic models, theory restricts the shape of functions, such as monotonicity or curvature conditions. This article reviews and presents a framework for constrained estimation and inference to test for shape conditions in parametric models. We show that “regional” shape-restricting estimators have important advantages in terms of model fit and flexibility (as opposed to standard “local” or “global” shape-restricting estimators). In our empirical illustration, this is the first article to impose and test for all shape restrictions required by economic theory simultaneously in the “Berndt and Wood” data. We find that this dataset is consistent with “duality theory,” whereas previous studies have found violations of economic theory. We discuss policy consequences for key parameters, such as whether energy and capital are complements or substitutes.     

论我国学前教育专业人才培养规格之嬗变

我国学前专业人才培养规格历史的基本走向是：清末民初时期的幼儿园教师培养制度初建,建国初期学习苏联幼儿园教师培养经验,改革开放初期提出幼儿园教师培养基本要求,21世纪初期肯定幼儿园教师专业地位,2010年以来幼儿园教师培养迈向标准化。学前教育专业学生培养的规格取向由只重保育到保教结合,由保姆到专业教师,由重理论学习到理论与实践相结合。学前专业人才培养规格从萌芽、形成走向逐渐清晰和成熟。审视和梳理我国学前教育专业人才培养规格的历史演变,总结其发展趋势,旨在准确认识和把握当前学前教育专业的人才培养规格,构建在培养规格科学定位指导下与之相匹配的课程体系。
