美国军队管理革命的开拓者——鲁特

伊莱休·鲁特针对美西战争中暴露出的美军事指挥和军队体制方面的问题，进行了五项改革：1．设立总参谋部；2．设立陆海军联合委员会；3．通过《国防法》，成立国民警卫队；4．对军队编制进行改革；5．军事教育改革。经过改革，美军事统帅体制提高了效率，军队编制趋向合理，为20世纪美国进行新的战争做好了准备。他是美国军事管理革命的开拓者。     

为国家教育妇女：加纳的教育改革与性别问题

1986改革中,加纳政府根据结构调整方案(SAP)和2020计划,关注教育中存在性别的不平等现象,努力解决女生在科学、数学和技术课程(SMT)的学业成绩、入学率等问题,并建立女子教育联合会.问题的解决要依靠真正普及免费的义务教育以及将妇女教育延伸到职业和高等教育机构.     

The Robustness of Trend Stationarity: An Illustration with the Extended Nelson-Plosser Dataset

We re-evaluate Andreu and Spanos's findings in favour of trend stationarity by considering the extended Nelson-Plosser data set. This expanded (to 1988) data set includes a period of rather different behaviour compared with the original Nelson-Plosser data used by Andreou and Spanos. We find that Andreou and Spanos's models (with only minor adjustments) exhibit remarable stability over this extended period, and indicate that their conclusions are more robust than they have shown.     

Testing symmetry under a skew Laplace model

We develop tests of hypothesis about symmetry based on samples from possibly asymmetric Laplace distributions and present exact and limiting distribution of the test statistics. We postulate that the test statistic derived under the Laplace model is a rational choice as a measure of skewness and can be used in testing symmetry for other, quite general classes of skew distributions. Our results are applied to foreign exchange rates for 15 currencies.

On Rao score and PearsonX 2 statistics in generalized linear models

The identity of the Rao score and PearsonX ² statistics is well known in the areas where the latter was first introduced: goodness-of-fit in contingency tables and binary responses. We show in this paper that the same identity holds when the two statistics are used for testing goodness-of-fit of Generalized Linear Models. We also highlight the connections that exist between the two statistics when they are used for the comparison of nested models. Finally, we discuss some merits of these unifying results.

硕士研究生入学英语考试英译汉试题的特点及翻译技巧

深入分析历年硕士研究生入学英语考试英译汉试题的特点,总结四方面特点,提出具有针对性的翻译方法和技巧作为对策:(1)试题中的词汇难以见词明义,需根据上下文选择确定词义或对词义进行引申;(2)句子的理解与翻译对上下文的依赖性很强,需使用还原法对原文中的替代、省略、变换等表达进行还原翻译;(3)句子较长,结构复杂,需采用分译法;(4)很多句子的表意方式和语序体现出英美人的思维习惯和特点,需作语序调整。     

Detecting parameter shift in garch models

This paper applies recent theories of testing for parameter constancy to the conditional variance in a GARCH model. The supremum Lagrange multiplier test for conditional Gaussian GARCH models and its robustified variants are discussed. The asymptotic null distribution of the test statistics are derived from the weak convergence of the scores, and the critical values from the hitting probability of squared Bessel process.

Monte Carlo studies on the finite sample size and power performance of the supremum LM tests are conducted. Applications of these tests to S&P 500 indicate that the hypothesis of stable conditional variance parameters can be rejected.

Testing the Equality of Two Exponential Distributions

This paper proposes an overlapping-based test statistic for testing the equality of two exponential distributions with different scale and location parameters. The test statistic is defined as the maximum likelihood estimate of the Weitzman's overlapping coefficient, which estimates the agreement of two densities. The proposed test statistic is derived in closed form. Simulated critical points are generated for the proposed test statistic for various sample sizes and significance levels via Monte Carlo Simulations. Statistical powers of the proposed test are computed via simulation studies and compared to those of the existing Log likelihood ratio test.
