Palm Distributions for Log Gaussian Cox Processes

This paper establishes a remarkable result regarding Palm distributions for a log Gaussian Cox process: the reduced Palm distribution for a log Gaussian Cox process is itself a log Gaussian Cox process that only differs from the original log Gaussian Cox process in the intensity function. This new result is used to study functional summaries for log Gaussian Cox processes.     

Monotonic change point estimation of generalized linear model-based regression profiles

In this article, a maximum likelihood estimator is derived in the generalized linear model-based regression profiles under monotonic change in Phase II. The performance of the proposed estimator is comprehensively investigated through some special cases, and compared with estimators under step change and drift. The results show that the proposed estimator has better performance in small and medium shifts under different increasing changes. Finally, the applicability of the proposed estimator is illustrated using a real case.     

Likelihood procedure for testing changes in skew normal model with applications to stock returns

The skew normal distribution family is an attractive distribution family due to its mathematical tractability and inclusion of the normal distribution as the special case. It has wide applications in many applied fields such as finance, economics, and medical research. Such a distribution family has been studied extensively since it was introduced by Azzalini in 1985 Azzalini, A. (1985). A class of distributions which includes the normal ones. Scandinavian Journal of Statistics 12:171–178. [Google Scholar] for the first time. Yet, few work has been done on the study of change point problem related to this distribution family. In this article, we propose the likelihood ratio test (LRT) to detect changes in the parameters of the skew normal distribution associated with some asymptotic results of the test statistic. Simulations have been conducted under different scenarios to investigate the performance of the proposed method. Comparisons to some other existing method indicate the comparable power of the method in detecting changes in parameters of the skew normal distribution model. Applications on two real data: Brazilian and Tanzanian stock returns illustrate the detection procedure.     

论得被害人承诺

得被害人承诺的行为是否阻却违法是一个备受争议的问题,法学界的通说是有条件的接收得被害人承诺的行为阻却违法,其适用范围应该仅限于被害人有权处理的私法益。其阻却违法的要件应该是,有承诺能力的承诺权人以明示或默示的方式,在侵害行为发生之前,任意性地表达对特定侵害结果的承诺,同时,还要求侵害人对承诺有明确认识。     

利益、博弈与养老金改革:对养老金制度的政治社会学分析

本文运用新多元主义理论探讨养老金改革中的利益博弈和私有化改革的发展趋势。对拉美和中东欧国家的研究表明,养老金的改革得益于其特殊的政治体制、外生行动者的支持和政府的强力推动,而否决点的缺失和社会组织力量的弱小又减少了养老金改革的阻力。但对美国、英国和欧洲的分析表明,由于利益的多元化、否决点的分散,以及强大的工会力量,社会保障私有化的改革困难重重。     

从接受角度比较吴越文化对鲁迅、周作人的影响

从接受角度论述吴越文化对周氏兄弟的影响 ,强调的是主体能力的亲近与吸收。周氏兄弟的经历与个性不同 ,造成了他们对吴越文化吸收的差别 ,由此形成了他们为人为文的迥异。     

晚清历史“传闻素材”中的史学意蕴

历史"传闻素材",从它的史料主要承载门类来看,在"正则"文献中所涉及者,有的被明确提示或被暗示出来,有的则在文本中被完全"异化",从形式上再也显不出传闻的属性;在稗野轶闻类史料中,自有其最为集中和醒目的反映;在"口述历史"类资料中,一般也有比较典型的体现。从史学理念的层面说,因为历史传闻当时具有真伪虚实莫辨的模糊性特点,故需要具备强化考辨的理念;因为历史传闻的真伪虚实未必都能考辨清楚,故需要抱有适当存疑的理念;因为历史传闻不乏在具体情节上失实而大致指向上符实的情况,故应当培养体悟神韵的理念;因为传闻入史对著述的文体风格会发生连带的影响,故不应排斥助益灵动的理念。这些,都是科学地认识和妥当地运用传闻素材所很应注意的。     

新时期地方综合性大学提高教学质量的四个要素

中国入世以后 ,中国的高等教育由精英化教育阶段走向大众化教育阶段 ,这在教育领域内引发了一场新的、极为深刻的变革 ,对地方综合性大学来讲 ,将面临着生存与发展的竞争。地方综合性大学能否适应形势的需要 ,关键在于教学的质量能否为社会所公认 ,而影响教学质量的“重要因素”——教学观念、师资队伍、教材和教学过程能否适应形势的需要 ,是地方综合性大学要考虑的头等大事。
