国外票据市场的发展及对我国的启示

随着现代经济的发展 ,票据作为一种支付信用结算工具 ,其低风险、高流动性的短期投资和融资功能日益受到企业、商业银行及广大投资者的重视 ,各种票据逐渐成为企业短期融资、银行提高资产负债的流动性管理和风险管理、满足投资者短期投资需要的重要货币市场工具。分析和研究票据市场发展现状及其特点 ,对我国票据市场发展有积极的借鉴意义。     

公民权与美国工业化时期缩短工时运动研究

在工业化时期,美国人们形成了"私人时间"的观念。他们普遍相信,过长的工时侵犯了自己的私人时间,而拥有私人时间是共和国公民的天然权利。这种思想成为缩短工时运动的重要思想基础,促进运动的蓬勃发展。然而,受契约自由传统的影响,运动仅取得了有限的成就,工人获得合理工作时间和私人时间的路途仍很艰辛漫长。     

Making the Best of a Bad Job? Female Part‐Timers’ Orientations and Attitudes to Work

This article uses data from 50 qualitative interviews with female part‐time workers in low‐level jobs in Britain to illustrate their attitudes, orientations and aspirations towards paid work. The research reports two main findings. Firstly, even female part‐time workers at the bottom end of the occupational structure are not a homogeneous group of workers. Secondly, they are not all highly satisfied with their jobs. The article argues that many women (especially those in working‐class households) still do not have a genuine choice between ‘family work’ and ‘market work’. It concludes by presenting a theoretical model of orientations to work.     

基于拥挤收费的动态出发时间选择

针对动态交通分配领域中往往假定所有车辆的出发时间是固定的不正确假设，探讨基于拥挤收费的出发时间选择问题的负效用函数，建立动态出发时间选择问题的变分不等式模型．结果表明，建立的变分不等式模型等价于动态用户最优出发时间选择问题.

Using a computer simulation game to teach family time use concepts

A computer simulation game designed to give students insights into family time use concepts has been used in an introductory family resource management class at Ohio State University and other universities. The game allows for planning for time use changes over the family life cycle. The game can give students insights into economic and sociological models of time use. It is possible that future versions of the game could be used in family counseling.His research interests include derivation of optimal decision-making rules for families and family financial management.Her research interests include financial management over the life course including financial ratios, baby boomers, and retirement. She received her Ph.D. in 1993 from The Ohio State University in Family Resource Management.His research interests include the time trade-offs made between couples, financial planning over the life cycle, and the interaction of time and money between families and their home-based businesses. He received his Ph.D. in 1993 from The Ohio State University in Family Resource Management.     

考虑交通时间与设备转换时间的跨区域就医调度优化问题

在资源共享时代背景下,跨区域就医可以很好地解决患者日益增长的就医需求与医疗资源紧张的矛盾。本论文以医疗联盟为研究对象,在关键医疗资源共享的前提下,通过患者跨区域就医实现就医诊断延误最小化,以满足患者就医需求。本研究同时考虑了患者跨区域交通时间与基于患者诊断类型的设备转换时间,以最小化患者就医总延迟为目标,分配患者就诊医院及优化患者就诊/检查顺序。针对该问题,论文首次提出以最早交货期原则（EDD rule）为基础,以患者再分配为主导的EDD-ReAss1和EDD-ReAss2启发式算法,结合局部搜索算法以进一步提高就医调度方案的质量,缩短患者诊断/检查等待时间。实验结果表明,新启发式算法EDD-ReAss1和EDD-ReAss2算法性能显著好于EDD,SPT和LPT等调度规则;在较短运算时间内Swap局部搜索算法性能最优。     

Curved Chaotic Map Time Series Models and Their Stochastic Reversals

This paper considers two types of chaotic map time series models, including the well-known tent, logistic and binary-shift maps as special cases; these are called curved tent and curved binary families. Deterministic behaviour is investigated by invariant distributions, Lyapunov exponents, and by serial dependency. Stochastic time reversal of the families is shown to produce models which have a broader range of stochastic and chaotic properties than their deterministic counterparts. The marginal distributions may have concentrations and restricted supports and are shown to be a non-standard class of invariant distribution. Dependenc y is generally weaker with the reversed stochastic models. The work gives a broad statistical account of deterministic and stochastically reversed map models, such as are emerging in random number generation, communica tion systems and cryptography     

北宋皇帝葬礼探考(上)

自汉迄唐,皇帝死后葬期长短不一,北宋一改旧观,恢复了“天子七月而葬”的儒家礼制;山陵役夫情况,正史中讳莫如深,作者从《金石萃编》等书中找出了有力证据;对山陵耗费,文章特别注意到“间接花费”和“山陵维护”等为常人所忽略的问题;嗣君为什么大建山陵?本文亦有自己的见解。     

基于提前期的多阶通用件库存模型

针对单个企业内部应用通用件的环境,在假定一个多阶生产系统的基础上,对应用通用件的库存量水平及其成本进行了分析,建立了多阶通用件库存模型,提出通过对采用通用件和不采用通用件的成本差异的比较,来决策多阶生产系统中在哪一阶工序采用通用件,并求解出每一阶工序优化的基本库存水平。
