唐宋书法观念研究

唐代、宋代的书法观念是中国古代封建社会书法观念的典型代表,二者之间又有颇为明显的异同之处。正如常人所说的＂唐书法＂就是说唐代书法对于字体规范、风格法度有着严密的内在要求,其实由于科举进仕的需要以及宋人文化素养的普通提升,宋代文人对＂法＂也有着自觉地遵循。同时,在宋代还大量出现了＂游与艺＂、＂以书为乐＂等更为轻松的书法观念。

民族素质是构成现代发展概念的重要内涵--民族素质研究之五

本文从与发展内涵相关的人类发展的诸项指数、国家实力概念的探讨情况,论述了民族素质在现代发展概念中的重要地位.     

论中华民族的多元民族文化观

民族文化观是人们对一个民族包括自身民族与他民族文化的观念、态度和价值取向。中华民族的多元文化观产生于多元的文化起源,形成于多民族长期的接触与交往。它既有多元的特征,也有一体的特征。在历史上,这种文化态度对中国各民族团结、国家和平统一以及社会发展都发挥了积极的作用。在世界格局与中国社会发生重大变革的当今社会,多元民族文化观依然具有很强的现实意义。     

政府监管与企业加入第三方国际环境审计的模糊博弈分析

针对政府环境监管与企业实施环境行为博弈分析中无法对双方的损益情况做出判断的问题,文章结合三角模糊数构建了政府监管和企业加入第三方国际环境审计的博弈模型,分别指出了纯策略纳什均衡和混合策略均衡情况需要满足的条件,讨论了政府与污染环境企业博弈策略的影响因素及作用机制,为政府监管与企业加入第三方国际环境审计顺利实施提供了相关建议。然后通过三角结构元方法对算例进行求解,验证了结论的正确性和可行性,引入三角模糊概念更加符合实际应用情况,拓展了第三方国际环境审计的应用背景。研究结果表明,政府对消费者消费的引导和对污染企业的惩罚对企业是否决定加入第三方国际环境审计起着举足轻重的作用。     

非均匀分布下区间数排序可能度计算模型及其应用

区间数排序的可能度计算模型是学术界一直在不断探索的基础性问题之一。区间数刻画着事物属性特征的取值范围,以往学术界都假设在区间内的取值服从均匀分布。本文将均匀分布推广到一般分布,运用概率论的方法,构建了一个新的区间数排序的可能度计算模型,由此修正了以往关于两个区间数全等的定义,提出了区间数形等的概念,同时进一步修正了可能度的自反性条件和区间数的综合排序方法,并将理论应用于多属性决策问题,给出了基本的决策过程,通过实例决策问题的计算,呈现了新理论和新方法的可行性和合理性,具有很好的推广应用价值。     

英国扩大留学生规模背景下的质量问题及反思

20世纪80年代以来,英国政府将扩大留学生规模作为高等教育国际化发展的重要战略政策。通过对近20年来英国留学生人数、留学生入学标准、优质学位授予比例、生师比、教育生均经费等数据变化趋势的分析,提出在这一经济利益驱动留学生规模扩张的过程中,英国留学生质量要求和标准正在放宽。如何使学生增长速度与优质资源生长速度相匹配、如何在获取短期经济效益的同时寻求高等教育长期可持续性发展的途径,是需要思考和解决的问题。     

Addressing potential prior‐data conflict when using informative priors in proof‐of‐concept studies

Bayesian methods are increasingly used in proof‐of‐concept studies. An important benefit of these methods is the potential to use informative priors, thereby reducing sample size. This is particularly relevant for treatment arms where there is a substantial amount of historical information such as placebo and active comparators. One issue with using an informative prior is the possibility of a mismatch between the informative prior and the observed data, referred to as prior‐data conflict. We focus on two methods for dealing with this: a testing approach and a mixture prior approach. The testing approach assesses prior‐data conflict by comparing the observed data to the prior predictive distribution and resorting to a non‐informative prior if prior‐data conflict is declared. The mixture prior approach uses a prior with a precise and diffuse component. We assess these approaches for the normal case via simulation and show they have some attractive features as compared with the standard one‐component informative prior. For example, when the discrepancy between the prior and the data is sufficiently marked, and intuitively, one feels less certain about the results, both the testing and mixture approaches typically yield wider posterior‐credible intervals than when there is no discrepancy. In contrast, when there is no discrepancy, the results of these approaches are typically similar to the standard approach. Whilst for any specific study, the operating characteristics of any selected approach should be assessed and agreed at the design stage; we believe these two approaches are each worthy of consideration.

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.
