Creating and sustaining competitive advantage in collaborative systems: The what and the how

Initially this paper asks two questions: In order to create and sustain competitive advantage through collaborative systems WHAT should be managed? and HOW should it be managed? It introduces the competitive business structure and reviews some of the global trends in manufacturing and business, which leads to focus on manage processes, value propositions and extended business processes. It then goes on to develop a model of the collaborative architecture for extended enterprises and demonstrates the validity of this architecture through a case study. It concludes that, in order to create and sustain competitive advantage, collaborative systems should facilitate the management of: the collaborative architecture of the extended enterprise; the extended business processes and the value proposition for each extended enterprise through a meta level management process. It also identifies areas for further research, such as better understanding of: the exact nature and interaction of multiple strategies within an enterprise; how to manage people/teams working along extended business processes; and the nature and prerequisites of the manage processes

高等教育大众化的体制性障碍与政策选择

我国高等教育发展除受制于经济发展的影响外 ,其滞后还源于传统体制性弊端。要想尽快进入高等教育大众化发展阶段 ,必须扫除其体制性障碍。因此 ,应根据现有状况把高等教育大众化政策分为近期和中长期政策。其中最主要的是适应社会主义市场经济特征 ,加大高等教育体制改革力度 ,重视教育的生产力属性和产业属性 ,并按经济资源特性区分高等教育资源 ,按照不同资源给予不同拨款方式 ,以实现高等教育资源的最佳配置     

Perfect simulation for correlated Poisson random variables conditioned to be positive

In this paper we present a perfect simulation method for obtaining perfect samples from collections of correlated Poisson random variables conditioned to be positive. We show how to use this method to produce a perfect sample from a Boolean model conditioned to cover a set of points: in W.S. Kendall and E. Thönnes (Pattern Recognition 32(9): 1569–1586, 1999), this special case was treated in a more complicated way. The method is applied to several simple examples where exact calculations can be made, so as to check correctness of the program using ²-tests, and some small-scale experiments are carried out to explore the behaviour of the conditioned Boolean model.     

论蒙古族亲属称谓所反映的民族文化现象

就如格里姆所讲 :“我们的语言也就是我们的历史。”语言能够比较全面而深刻地体现民族的特点 ,这是民族的其他特征所不能比拟的 ,透过现代语言 ,可探索出该民族不同时期的历史进程 ,特别是民族语言中的亲属称谓词和固定词语中所蕴涵的文化遗迹最为丰富 ,也最深刻     

中国企业部门信用风险溢价期限结构与宏观经济因子

近年来，中国企业部门债务风险不断暴露，其是否会引发系统性信用危机正成为焦点。本文着眼于中国企业部门信用风险累积与暴露背后的宏观经济现实，在简约模型中引入结构向量自回归模型（SVAR），将经济冲击区分为总供给冲击、总需求冲击和货币政策冲击，以此研究各宏观经济因子对中国企业部门信用风险溢价期限结构的影响特征，从而揭示中国企业部门信用风险定价的宏观经济机理。本文发现，正向的总供给冲击和货币政策冲击有助于降低中国企业部门信用风险溢价，但正向的总需求冲击则会推高中国企业部门信用风险溢价，自2011年以来持续处于高位水平的信用风险溢价的主要根源正是4万亿经济刺激计划所带来的扩张性总需求，因此欲从根本上降低中国企业部门信用风险水平，应紧缩社会总需求，并通过制度改革和结构调整，改善社会总供给。     

基于LSTM神经网络的金融时间序列预测

本文提出将小波分析与纳入时间序列依赖特征的长短期记忆（LSTM）神经网络相结合，构建金融时间序列数据预测模型，以克服现有模型对金融时间序列数据非平稳、非线性、序列相关等复杂特征以及数据间非线性交互关系无法反映的缺陷。同时，以道琼斯工业指数日收盘价为例，探究LSTM神经网络对实际金融时间序列数据的预测能力，比较其与多层感知机、支持向量机、K近邻、GARCH四种模型的预测效果。实证结果表明LSTM神经网络具有更高的预测精度，能够有效预测金融时间序列数据的长短期动态变化趋势，说明了其对金融时间序列数据预测的适用性与有效性。此外，对金融时间序列数据进行小波分解与重构，可有效提高LSTM预测模型的泛化能力，以及对长短期动态趋势的预测精度。     

'I made some mistakes . . . but I love them dearly' the views of parents of children in informal kinship care

In-depth semi-structured interviews with 30 parents of children living with relatives in informal kinship care arrangements revealed the parents' views of the reasons for the informal kinship care arrangements, quality of their relationships with the children and their caregivers, their current and future roles in their children's lives, feelings experienced when with and away from the children, positive and negative aspects of kinship care, future goals and dreams for their children, and their assessments of their own strengths and challenges. Results of these interviews suggest several implications for social work practice and research.     

顾客时代普通高校继续教育的市场定位及其发展策略研究

产品时代已经结束,顾客时代真正来临了。普通高校继续教育业务部门战略思维模式应契合消费者的思维模式,要把拓展办学空间、获得市场份额的立足点定位在创造学生的顾客价值、回报学生的知识投资上。因此,必须正确认识继续教育与普通教育的关系,实施差异化战略和"以顾客为中心"的营销策略,切实维护学校品牌价值,进而提升其市场核心竞争力。
