Analysis of some ruin-related quantities in a Markov-modulated risk model

In this paper, we study the joint Laplace transform and probability generating function of some random quantities that occur in each environment state by the time of ruin in a Markov-modulated risk process. These quantities include the duration spent in each state, the number of claims and the aggregate amount of claims that occurred in each state by the time of ruin. Explicit formulae for the joint transforms, given the initial surplus, and the initial and terminal environment states, are expressed in terms of a matrix version of the scale function. Moments and covariances of these ruin-related quantities are obtained and numerical illustrations are presented. The joint transform of the duration spent in each state, the number of claims, and the aggregate amount of claims that occurred in each state by the time the surplus attains a certain level are also investigated.     

略论新媒体时代广西非物质文化遗产的创新保护

在新媒体语境下,广西壮族自治区非物质文化遗产的保护工作应开辟新途径,让新媒体发挥其优势,承担“非遗”传承的重任。借助新媒体拓宽广西“非遗”的传播途径及加速广西“非遗”“活态化”的创新发展,以数字化技术推进广西“非遗”的产业化及其传承人的普及化培养,不失为有效的创新方法。在充分利用新媒体技术进行“非遗”保护工作时也应遵循主体性、优先性、本真性和整体性等原则。     

基于环境传感器和穿戴式传感器的行为异常检测

针对独居老人频繁出现行为异常的情况,提出了基于热释电红外传感器和穿戴式传感器的老人行为异常检测系 统。设计了行为异常检测的硬件环境,介绍了红外传感器和穿戴式传感器的工作原理,提出了依据重力加速度所在轴向 检测老人躺下位置是否发生异常的方法,并融合了红外传感器和穿戴式传感器的信息对躺下位置异常进行检测。在1 居室的家庭环境中对位置异常检测的方法进行验证,通过实验的方法验证了算法的可行性,并确定了检测躺下状态的阈 值。系统能有效实现对独居老人是否发生躺下位置异常进行检测。     

国家投资科研项目成果的知识产权归属探讨

通过对国家投资产生的科研成果现状的分析以及与国外的相关政策的对比,讨论在不同的情况下,有可能发生的知识产权归属争议;其次,讨论在职务发明、非职务发明、有合同约定、没有约定等情况下怎样理顺权属关系。并对今后知识产权在归属方面的发展趋势作了较为深入的探讨。国家的法律或者政策应该在有效地处理和化解来自各方的权属 纠纷和矛盾,充分调动国家、集体和个人的积极性,鼓励在知识经济条件下努力创造出更多、更有价值的知识产权方面,发挥更大的作用。     

The Pinochet case: cosmopolitanism and intermestic human rights

This article explores the Pinochet case, widely heralded as a landmark, as a case of 'intermestic' human rights that raises difficult normative and empirical questions concerning cosmopolitan justice. The article is a contribution to the sociology of human rights from the perspective of methodological cosmopolitanism, developing conceptual tools and methods to study how cosmopolitanizing state institutions and cultural norms are inter-related. The argument is made that in order to understand issues of cosmopolitan justice, sociologists must give more consideration to political culture.     

State transition modeling of complex monitored health data

This article considers the analysis of complex monitored health data, where often one or several signals are reflecting the current health status that can be represented by a finite number of states, in addition to a set of covariates. In particular, we consider a novel application of a non-parametric state intensity regression method in order to study time-dependent effects of covariates on the state transition intensities. The method can handle baseline, time varying as well as dynamic covariates. Because of the non-parametric nature, the method can handle different data types and challenges under minimal assumptions. If the signal that is reflecting the current health status is of continuous nature, we propose the application of a weighted median and a hysteresis filter as data pre-processing steps in order to facilitate robust analysis. In intensity regression, covariates can be aggregated by a suitable functional form over a time history window. We propose to study the estimated cumulative regression parameters for different choices of the time history window in order to investigate short- and long-term effects of the given covariates. The proposed framework is discussed and applied to resuscitation data of newborns collected in Tanzania.     

经济史视角下的清末民初官方邮局与民信局之争

官方邮局与民信局为争夺邮政市场,在资费与业务等领域展开激烈竞争。为适应形势变化,民信局开始利用新式交通工具发展业务。民信局虽然通过请愿、走私等形式规避官邮控制,但还是走向衰落。民信局与官方邮局的竞争促使官方邮局更趋商业化。民信局积极利用轮船等新式交通工具,而大清邮局则积极学习民信局优点,拓展业务范围。     

基于模糊信息熵的环境管理过程控制能力

建立了环境管理过程的闭环过程控制系统模型,用模糊控制系统表达环境管理过程中的不确定性,分析了环境管理过程的控制能力,建立了过程控制能力函数。将信息熵引入模糊环境过程控制函数的参数识别,建立了环境管理过程度量方法。同时,建立了环境管理过程决策支持系统,以实现环境管理过程的参数识别和能力评估。     

论外层空间物体的登记国

外层空间物体的登记国是指依《登记公约》进行登记的一个发射国。当存在多个发射国时,应当共同决定登记国。在无法达成一致时,应按照一定的规则确定登记国。如果外层空间物体所有权转移给其他发射国,可以进行变更登记;如果转移给非发射国,则不能由非发射国进行登记,但非发射国可以对外层空间物体行使管辖权或控制权。外层空间物体的登记对登记国具有一定的法律效果。     

对国有资产中有形资产流失问题的探讨

国有资产中有形资产的流失存在动态流失与静态流失两种形式,动态流失因产权不清、管理不严或产权交易中规则不健全所致,具体又可分为经营性动态流失和人为性动态流失．静态流失与其是否进入市场交易有关．加强经济立法,完善和发展产权交易市场等可减少或避免国有有形资产的流失。
