左江花山岩画铜鼓考

左江花山岩画文化景观成功入选世界遗产名录后,依然有未解的千年之谜。经对左江花山岩画中铜鼓的族属、类型、传承发展、文化功能等进行多角度考证,确认左江花山岩画所绘铜鼓为骆越人所有,其类型为万家坝型、石寨山型和东山型早期铜鼓;岩画中的铜鼓不仅是部族首领权力的象征,还是通天礼神、汇聚人心、指挥军阵、人神共娱的重要礼器、响器及乐器;东汉马援缴骆越铜鼓后,左江流域骆越后裔仍有用鼓、尚鼓的习俗,这是对左江花山岩画铜鼓的一种继承与发展。与此同时,骆越人先进的青铜铸造技术亦为铜鼓在这一地区的传承与发展提供了物质基础。     

清代驻藏大臣的设置及其历史作用

设立驻藏大臣是清王朝加强对西藏治理的一项重要举措。文章认为驻藏大臣的设置是清朝在总结历史经验的基础上,根据西藏当时的实际情况而采取的一项行之有效的管理策略。它对西藏的社会政治产生了十分深刻的影响。     

由丝路汉简看古代的会计核算制度?

会计制度是管理国家经济工作的一种重要工具。汉代丝绸之路开辟后,这种经济管理也扩大到对西域都护府的经济管理。几份出土的西域都护府辖下的财务报表真实地再现了两千年前汉代会计制度的原貌,也更让今人理解了古代丝绸之路开辟对当时的经济影响及会计法的重要性。     

福利国家为什么需要慈善部门？

自福利国家陷入危机以来,慈善部门在福利国家中的功能问题一直没有得到全面和系统的讨论。福利多元主义者将慈善部门视为政府的合作伙伴,希望通过政府委托慈善部门提供公共服务的方式来缓解福利国家的危机;新自由主义者则认为这一定位会使慈善部门对政府的资金产生依赖,使慈善部门失去独立性,因而主张以市场化的方式来解决国家的福利供给问题,让慈善部门在公共服务以外的领域发挥作用。辨析福利多元主义与新自由主义的争论,结合全球化时代慈善部门出现的新特征,可以看到,慈善部门在福利国家中具有绩效提升、结构补充、价值倡导、民主促进、就业吸收和国际支援等六大功能。     

论食品安全事件中的良性媒体应对

食品安全事件是近年来全球公共安全问题中的热点,由于食品安全的重要性、食品安全事件的公众效应以及基于传媒的属性,媒体常将其作为关注的热点。媒体在食品安全事件中发挥着监测预警、沟通信息、舆论引导等功能,同时也存在关注视角的选择性和职业自律的松懈等不足。作为一种社会公共资源和社会监督力量,基于传媒良知和职业操守,媒体在食品安全事件中必须形成一套良性的应对机制,包括建立信息有效传播机制、建立食品安全事件相关方的沟通协调机制、建立媒体自律机制等。     

Inference in Semi‐Parametric Dynamic Models for Repeated Count Data

This paper deals with a longitudinal semi‐parametric regression model in a generalised linear model setup for repeated count data collected from a large number of independent individuals. To accommodate the longitudinal correlations, we consider a dynamic model for repeated counts which has decaying auto‐correlations as the time lag increases between the repeated responses. The semi‐parametric regression function involved in the model contains a specified regression function in some suitable time‐dependent covariates and a non‐parametric function in some other time‐dependent covariates. As far as the inference is concerned, because the non‐parametric function is of secondary interest, we estimate this function consistently using the independence assumption‐based well‐known quasi‐likelihood approach. Next, the proposed longitudinal correlation structure and the estimate of the non‐parametric function are used to develop a semi‐parametric generalised quasi‐likelihood approach for consistent and efficient estimation of the regression effects in the parametric regression function. The finite sample performance of the proposed estimation approach is examined through an intensive simulation study based on both large and small samples. Both balanced and unbalanced cluster sizes are incorporated in the simulation study. The asymptotic performances of the estimators are given. The estimation methodology is illustrated by reanalysing the well‐known health care utilisation data consisting of counts of yearly visits to a physician by 180 individuals for four years and several important primary and secondary covariates.     

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.     

我国居民文化消费影响因素探析

运用我国1983—2012年的数据,通过实证分析考察了可支配收入、教育水平、金融发展和政府文化事业支出对我国居民文化消费的影响。长期均衡分析结果表明,教育水平和金融发展对我国居民文化消费具有显著的促进作用;教育水平提高1%,居民文化消费增加0.454%;金融机构信贷提高1%,居民文化消费增加0.363%;可支配收入和政府文化事业支出对居民文化消费的影响不显著。脉冲响应分析结果表明,可支配收入冲击对居民文化消费的影响在短期由正向转为负向,教育水平冲击和金融发展冲击对居民文化消费短期具有正向影响,政府文化事业支出冲击对居民文化消费短期具有负面影响。根据实证分析的结论,文章提出了扩大我国居民文化消费的政策建议。     

论汉魏六朝仪式歌辞的文化功能与传播特点

仪式歌辞是为满足封建王朝各种仪式活动需要而创作音乐歌辞,因其满足仪式活动之需的特殊功能,内容上强调其与仪式活动符号象征的一致性,形式上多采用典雅的四言正格,在传播方式上呈现出程序性、依附性、组织性和共时性特点。仪式歌辞特殊的文化功能和传播特点决定了其传播效果的局限性,在传播范围的拓展性、传播时间的延续性方面均不能与娱乐歌辞相比,人们对仪式歌辞的接受,也主要是从其内容的“象征图式”和“意象结构”出发的,是否美听悦耳不是接受重点。     

A New Quantile Function with Applications to Reliability Analysis

In this article, we propose a new class of distributions defined by a quantile function, which nests several distributions as its members. The quantile function proposed here is the sum of the quantile functions of the generalized Pareto and Weibull distributions. Various distributional properties and reliability characteristics of the class are discussed. The estimation of the parameters of the model using L-moments is studied. Finally, we apply the model to a real life dataset.
