准谐振式DC─AC变换器

准谐振技术是近年来提出的减小开关损耗，提高变换器效率的一种新技术。本文从两种基本的ＤＣ─ＡＣ变换方式开始，介绍了采用准谐振技术的各种ＤＣ─ＡＣ变换器的电路，工作原理及实验（仿真）结果。     

我国反垄断民事诉讼举证责任分配制度之检讨——以典型案例为样本

我国反垄断民事诉讼中原告胜诉率极低，其根本原因在于原告举证困难。这与我国目前对于反垄断民事诉讼举证责任分配的处理直接相关。反垄断民事诉讼较为特殊，不能适用民事诉讼的一般举证责任分配法则，而应实行举证责任倒置制度，将本应由原告承担的部分举证责任分配给被告。最高人民法院《反垄断司法解释》对此有所考量，但仍显保守，对减轻原告举证责任效果有限。奇虎公司诉腾讯公司垄断纠纷案及锐邦涌和公司诉强生公司垄断纠纷案也表明，我国法院在反垄断民事诉讼中分配给原告的举证责任过重，不利于实现反垄断民事诉讼的目标。     

An algorithm for the estimation of poisson regressions involving structural change

We consider the estimation of Poisson regression models in which structural variation in a subset of the parameters is permitted. It is noted that coventional estimation algorithms are likely to impose restrictions on the number of explanatory variables and the number of structural regimes. We propose an alternative algorithm that implements partitioned matrix inversion and thereby avoids restictions on the size of the model. The algorithm is applied to a model of shopping behavior Adjustments in the algorithm necessary for dealing with censored data are detailed.     

Estimation and Inference in Two-Step Econometric Models

A commonly used procedure in a wide class of empirical applications is to impute unobserved regressors, such as expectations, from an auxiliary econometric model. This two-step (T-S) procedure fails to account for the fact that imputed regressors are measured with sampling error, so hypothesis tests based on the estimated covariance matrix of the second-step estimator are biased, even in large samples. We present a simple yet general method of calculating asymptotically correct standard errors in T-S models. The procedure may be applied even when joint estimation methods, such as full information maximum likelihood, are inappropriate or computationally infeasible. We present two examples from recent empirical literature in which these corrections have a major impact on hypothesis testing.     

高等数学教学中若干问题的探讨

性骚扰问题成为当前突出的社会问题。按照“谁主张,谁举证”的原则,受害者往往由于证据不足而败诉。有学者认为将举证责任倒置原则应用于反性骚扰诉讼中,以此来突破证据瓶颈。笔者认为,将举证责任倒置原则应用于性骚扰诉讼中既无法律依据也可能造成很大的法律风险,诉讼中法官可采用“诚实信用原则”,在合理范围内分配举证责任。     

公诉案件举证责任的分配

我国刑事诉讼法对举证责任的规定很简略,理论上也少有针对性的探究,司法实践中标准不明,随意性大。文章根据我国的立法规定和司法解释,结合外国立法和举证责任分配的基本原理,探讨公诉案件审判程序中举证责任的具体分配问题,以期对司法实践有所裨益。     

个人信息损害赔偿问题研究

损害赔偿问题是个人信息安全的戈尔迪之结。愈演愈烈的个人信息滥用行为与损害赔偿制度不完善有关。在界定个人信息控制权为人格权的基础上,综合考量损害事实、侵权行为人的过错以及获利等因素,确定精神损害赔偿额。通过举证责任倒置和增设集体诉讼,完善保障个人信息安全的程序机制,进而从实体法和程序法两个层面缓解个人信息在大数据时代的安全危机。     

“依赖逆反”:社会形态变革的“临界点”及其当代启示

马克思主义经典作家基于唯物史观对社会形态变革所做的论断是科学性和真理性的统一。生产力的发展是社会变革的根本动力,它必然带动生产关系的变革,形成新的经济利益关系,从而为新的社会形态出现奠定基础。马克思主义社会形态变革理论使人们能够更好地把握社会形态变革的"临界点",即由低级形态向高级形态发展的节点。把握和研究社会形态变革"临界点"的形成、发展及其作用对于我们剖析当代资本主义社会发展具有重要的指导意义。     

《喧哗与骚动》的艺术表现手法

<喧哗与骚动>艺术表现手法的独创性和多样性是令人惊叹的,威廉·福克纳为了能准确描写及传达出美国南方的没落和精神世界的危机,以看似混乱矛盾的"多角度"、"时序颠倒"、"意识流"、"象征"、"引喻"、"反讽"等叙事和表现手法,来强调叙述者混沌迷乱的内心世界,以及叙述者所生活的外部世界的激烈的历史性变革.     

Simulating from polynomial-normal distributions

The family of polynomial-normal distributions includes a number of widely used distributions, such as the Gram–Charlier and Edgeworth distributions. In this note, we present three simple algorithms, (i) CDF Inversion, (ii) Acceptance–Rejection, (iii) and Ratio–of–Uniforms, for simulating variates from a polynomial-normal distribution. Details on the efficiency of the Acceptance–Rejection and the Ratio–of–Uniforms algorithms and a comparison across the various implementations are provided.
