Moments of suprema of random variables

The supremum of random variables representing a sequence of rewards is of interest in establishing the existence of optimal stopping rules. Necessary and sufficient conditions are given for existence of moments of sup_n(X_n ? c_n) and sup_n(S_n ? c_n) where X₁, X₂, … are i.i.d. random variables, S_n = X₁ + … + X_n, and c_n = (nL(n))^1/r, 0 < r < 2, L = 1, L = log, and L = log log. Following Cohn (1974), “rates of convergence” results are used in the proof.     

论西夏的司法制度

西夏的行政、军事机关,一般都兼有案件审判和督察复核职责。司法诉讼主要为刑事诉讼,即使民事案件,也是用刑事判断。对人犯的逮捕只需长官的指令,而不履行法律手续。法律上只有对逮捕人的督察,防其奸伪、贪纵、暴掠以及无故杀伤人犯,人犯拒捕反抗格杀勿论。     

Ranking of the Most Prolific Authors,Universities, and Organizations in the Journal of Organizational Behavior Management

ABSTRACT

Over the years, reviews in behavior analysis have sought to identify the most prolific researchers and institutions. The goal of these reviews was to offer one resource for behavior analysts to identify experts in behavior analysis and quality graduate programs. However, most of these reviews omitted the Journal of Organizational Behavior Management (JOBM), making the results less relevant to those who work in organizational behavior management. The purpose of this review was to extend previous findings and identify the most published researchers, academic institutions, and organizations in JOBM since its inception. Furthermore, we calculated the citation rate (per year, per article) for each of the top 20 most published authors. The results, implications, and opportunities for further analysis are discussed.     

Stochastic comparisons on sample extremes of dependent and heterogenous observations

Stochastic comparison on order statistics from heterogeneous-dependent observations has been paid lots of attention recently. This paper devotes to investigating the ordering properties of order statistics from dependent observations. We derive the usual stochastic order for sample minimums and the second smallest order statistic, the dispersive order and the star order for minimums of samples having proportional hazards and Archimedean survival copulas. Similar ordering results are also obtained for maximums and the second largest order statistic of samples having proportional reversed hazards and Archimedean copulas. Several examples illustrating the main results are presented as well.     

Kernel density estimation under negative superadditive dependence and its application for real data

In this paper, the kernel density estimator for negatively superadditive dependent random variables is studied. The exponential inequalities and the exponential rate for the kernel estimator of density function with a uniform version, over compact sets are investigated. Also, the optimal bandwidth rate of the estimator is obtained using mean integrated squared error. The results are generalized and used to improve the ones obtained for the case of associated sequences. As an application, FGM sequences that fulfil our assumptions are investigated. Also, the convergence rate of the kernel density estimator is illustrated via a simulation study. Moreover, a real data analysis is presented.

严格责任的反思

我国刑法理论界中关于严格责任的概念和种类有较大分歧,从新的角度对其进行了反思和梳理,使我国的严格责任理论更为科学,并沿着理性的思路对严格责任在我国之所以存在的理论基础进行了充分论证。严格责任与我国传统意义上的罪过责任和犯罪构成理论存在较大差异和逻辑矛盾,笔者也试着对这些问题进行了诠释、论证和解决。     

犯罪学中的"犯罪"概念哲学角度评析

犯罪学是研究犯罪现象的科学.界定犯罪概念,了解犯罪的内涵和外延,是每个犯罪学学者研究的前提和基石.由于刑法学、刑事诉讼法学、刑事侦查学等刑事法学学科都以犯罪现象作为研究客体,加之犯罪现象自身复杂性、多变性,在研究中就出现了犯罪概念的多元化,不同派别的学者见仁见智.
