民国时期甘宁青边疆教育研究述评

推行边疆教育是南京国民政府的一项重要举措,在当时取得了一定成效。对此问题的研究具有积极的现实意义。本文对民国以来甘宁青边疆教育研究状况进行简要述评,并提出今后应注重研究的问题。     

唐宋时期回族先民对西北商业经济的开发与贡献

重视商业经济,是伊斯兰教的特点之一。唐宋时期,伴随着伊斯兰教的传入,回族先民对西北商业经济进行了开发。他们一方面继承了阿拉伯商业的传统,另一方面在新的环境下,又有所创新、有所发展。在长期不断的开发中,为西北区域经济的繁荣与发展,做出了重要的贡献。     

怒俅殖边:近代云南一次意义深远的边疆开发

民国初期 ,云南地方政府在滇西北怒江少数民族地区的设治经营 ,是云南边疆民族地区发展历史上的一个重大事件 ,它对怒江地区的社会发展和各民族的进步产生了极其重大而深远的影响。本文阐述了“怒俅殖边”这一历史进程 ,认为它使怒江地区的民族关系得到明显的调整与改善 ;使怒江经济社会发展进入一个新时期 ;遏制了英国侵略势头 ,对巩固滇西北边防产生了重要和深远的影响     

回族服饰文化与伊斯兰教

自元、明以来 ,回族的服饰在不断变化 ,但其中的宗教基因却保留不变。它既表现出华夏民族的文化传承 ,又涵盖着伊斯兰宗教文化的教义、教规与伦理道德 ,在中国少数民族服饰中独树一帜 ,为具有美观、端庄、俭朴等特色且表现出民族心理及审美观念的服饰文化。回族服饰文化是宗教礼仪服饰文化与世俗服饰文化的有机结合 ,体现着回族人民的智慧与民族精神     

Analysis of some ruin-related quantities in a Markov-modulated risk model

In this paper, we study the joint Laplace transform and probability generating function of some random quantities that occur in each environment state by the time of ruin in a Markov-modulated risk process. These quantities include the duration spent in each state, the number of claims and the aggregate amount of claims that occurred in each state by the time of ruin. Explicit formulae for the joint transforms, given the initial surplus, and the initial and terminal environment states, are expressed in terms of a matrix version of the scale function. Moments and covariances of these ruin-related quantities are obtained and numerical illustrations are presented. The joint transform of the duration spent in each state, the number of claims, and the aggregate amount of claims that occurred in each state by the time the surplus attains a certain level are also investigated.     

Testing Serial Correlation in Partially Linear Additive Errors-in-variables Models

This article considers testing serial correlation in partially linear additive errors-in-variables model. Based on the empirical likelihood based approach, a test statistic was proposed, and it was shown to follow asymptotically a chi-square distribution under the null hypothesis of no serial correlation. Finally, some simulation studies are conducted to illustrate the performance of the proposed method.     

A Rejection Principle for Sequential Tests of Multiple Hypotheses Controlling Familywise Error Rates

We present a unifying approach to multiple testing procedures for sequential (or streaming) data by giving sufficient conditions for a sequential multiple testing procedure to control the familywise error rate (FWER). Together, we call these conditions a ‘rejection principle for sequential tests’, which we then apply to some existing sequential multiple testing procedures to give simplified understanding of their FWER control. Next, the principle is applied to derive two new sequential multiple testing procedures with provable FWER control, one for testing hypotheses in order and another for closed testing. Examples of these new procedures are given by applying them to a chromosome aberration data set and finding the maximum safe dose of a treatment.     

A nonparametric hypothesis test for heteroscedasticity

In this paper, a hypothesis test for heteroscedasticity is proposed in a nonparametric regression model. The test statistic, which uses the residuals from a nonparametric fit of the mean function, is based on an adaptation of the well-known Levene's test. Using the recent theory for analysis of variance when the number of factor levels goes to infinity, the asymptotic distribution of the test statistic is established under the null hypothesis of homocedasticity and under local alternatives. Simulations suggest that the proposed test performs well in several situations, especially when the variance is a nonlinear function of the predictor.     

清至民国时期的东北民神

民神信仰是民俗文化的重要组成部分,东北地区由于特殊的历史和地理背景,在其民神形成的历史过程中,既有与全国民神共同的特点,也有自身的地城特征.
