论机动车交通事故民事赔偿责任革新：填补性到惩罚性

机动车交通事故民事赔偿一贯采取的填补性赔偿,是对机动车交通事故主观因素与客观因素考虑欠妥的结果。主观因素方面,机动车交通事故应当区分当事人的过错程度,即区分故意与过失、一般过失与重大过失。在归责原则上应全面坚持过错责任原则,符合个人就自身行为所肇致的损害应负赔偿责任的基本观念。客观因素方面,机动车交通事故损害不应固守类型化区分,而应进行程度化区分,即轻微损害、一般损害、重大损害。主观因素与客观因素相结合,机动车交通事故责任中应当引入惩罚性赔偿,搭建填补性与惩罚性结合的赔偿架构。     

2000m~3二甲醚球罐的在线检测及有限元分析

首先,使用多通道声发射检测仪PAC SAMOS-48检测在用2000m3二甲醚球形储罐,判定出该设备存在表面裂纹缺陷及其所处位置。然后,采用超声波检测方法,确定了裂纹形状和大小。用Newman—Raju方法研究了表征裂纹缺陷前沿应力场以及位移场的重要参量即应力强度因子,并利用ANSYS建立简化的有限元模型,最终得到裂纹的应力云图和该裂纹前沿应力强度因子值,与工程估算方法得到的数值进行对比,结果表明有限元方法应用于压力容器缺陷的分析是适用的。     

Statistical analysis of a two-unit dependent repairable system

Maximum likelihood estimators are investigated a for lr-out-of 2:G repairable system when failures and repairs are statistically dependent. Under two censoring schemes Accelerated Life Testing Procedure (ALTP) is used to obtain the estimates. Information matrices are supplied and a special case when the failure and repair phenomenon are independent of each other is considered.

How to Teach by the Unit Method

Using data from the National Center for Educational Statistics research spanning fifteen years, researchers examined the impact of national educational policy implementation on the role of social studies in elementary schools. Specifically, with the reauthorization of No Child Left Behind (NCLB) in 2007 and the continuation of federal-mandated testing of English language arts (ELA) and mathematics in grades three through five, researchers sought to understand how policy decisions to extend testing to science affected teacher decisions in regard to instructional time allocations for core subject areas of ELA, mathematics, science, and social studies in elementary schools. Results of this quantitative study offer large-scale evidence of the declining role of social studies in an era in which testing is clearly linked to subject-area importance. Findings provide an overview of the national scope of testing and the ramifications for social studies in elementary schools. Researchers conclude that curriculum standardization, accountability, and high-stakes testing have had adverse affects on social studies time allotments in comparison to tested subjects.     

Conducting research using web-based questionnaires: Practical,methodological, and ethical considerations

The use of the internet for social science research is becoming increasingly common. This paper outlines practical, methodological and ethical issues for researchers to consider when using web-based questionnaires. This is illustrated by consideration of the authors' own experience of conducting a study into the phenomenon of self-harm.

Stochastic comparisons of order statistics,with applications in relibility

This paper reviews recent developments in the stochastic comparison of order statistics. The results discussed are basically: (l) Stochastic comparisons of linear combinations of order statistics from distributions F and G where G^?1 F is convex or starshaped. (2) Stochastic comparisons of individual order statistics and of vectors of order statistics from underlying heterogeneous distributions by the use of majorization and Schur function theory. (3) Stochastic comparison of random processes. Applications to reliability problems are presented illustrating the use and value of the theoretical results described     

Bayes Analysis and Comparison of Accelerated Weibull and Accelerated Birnbaum–Saunders Models

Several models are proposed in the literature for modeling fatigue data resulting from materials subject to cyclic stress and strain. Accelerated Weibull and accelerated Birnbaum–Saunders distributions are most commonly used models. Whereas the accelerated Weibull model is easier compared to accelerated Birnbaum–Saunders, it fails to represent the situation equally well. The present article focuses on Bayes analysis of the two models and provides a comparison based on some important Bayesian tools. Model compatibility study using predictive simulation ideas is preceded by the said comparison. Throughout, the posterior simulations are carried out by Markov chain Monte Carlo procedure.     

Nonparametric Methods in Continuous Time Model Specification

Some popular parametric diffusion processes have been assumed as such underlying diffusion processes. This paper considers an important case where both the drift and volatility functions of the underlying diffusion process are unknown functions of the underlying process, and then proposes using two novel testing procedures for the parametric specification of both the drift and diffusion functions. The finite-sample properties of the proposed tests are assessed through using data generated from four popular parametric models. In our implementation, we suggest using a simulated critical value for each case in addition to the use of an asymptotic critical value. Our detailed studies show that there is little size distortion when using a simulated critical value while the proposed tests have some size distortions when using an asymptotic critical value in each case.
