“监督”美国：越南战争中的加拿大

从1954年到1973年加拿大参加了针对越南和平问题的国际监督委员会。由于当时的国际环境、加拿大与美国的“特殊关系”以及美国对日内瓦协议的破坏,加拿大在国际监督委员会中面临着“两难困境”－既监督美国又被美国所利用。随着美国在越南干涉的加紧和战争的不断升级,加拿大对美国的越南政策越来越不满。加拿大的“监督”一定程度上影响了美国的越南政策。70年代初美国最终撤出越南,加拿大对越南的国际监督责任也以失败告终。

获得1.2K低温的实验研究

本文从低温传热的观点出发,通过对减压过程的传热分析和温度分布的测量,提出建立该类低温装置应遵循的基本原则;发现低温实验装置中,主颈管的导热漏热占主导地位,减压过程中冷气流大小对温度分布的影响很敏感,改变了颈口热辐射决定的轴向距离、77K辐射屏位置及屏间距.实验对减压降温过程进行了动态测量,并提出液氦玻璃杜瓦的非正常输入的概念。     

Investigating purchasing-sequence patterns for financial services using Markov, MTD and MTDg models

In the past, several authors have found evidence for the existence of a priority pattern of acquisition for durable goods, as well as for financial services. Its usefulness lies in the fact that if the position of a particular customer in this acquisition sequence is known, one can predict what service will be acquired next by that customer. In this paper, we analyse purchase sequences of financial services to identify cross-buying patterns, which might be used to discover cross-selling opportunities as part of customer relationship management (CRM). Hereby, special attention is paid to transitions, which might encourage bank-only or insurance-only customers to become financial-services customers. We introduce the mixture transition distribution (MTD) model as a parsimonious alternative to the Markov model for use in the analysis of marketing problems. An interesting extension on the MTD model is the MTDg model, which is able to represent situations where the relationship between each lag and the current state differs. We illustrate the MTD and MTDg model on acquisition sequences of customers of a major financial-services company and compare the fit of these models with that of the corresponding Markov model. Our results are in favor of the MTD and MTDg models. Therefore, the MTD as well as the MTDg transition matrices are investigated to reveal cross-buying patterns. The results are valuable to product managers as they clarify the customer flows among product groups. In some cases, the lag-specific transition matrices of the MTDg model give better insight into the acquisition patterns than the general transition matrix of the MTD model.     

再谈陈独秀与大革命失败

中国大革命的失败是由历史的、主观的、客观的诸多因素造成的 ,虽然陈独秀也负有一定的不可推卸的个人责任 ,但失败的重要原因是由于我党所处的特殊历史环境和共产国际的错误领导造成的 ,所以不能过分地夸大陈独秀在大革命失败中的个人的责任     

Ellen Gleditsch: Pioneer Woman in Radiochemistry

We present the life and work of the Norwegian scientist Ellen Gleditsch (1879-1968) in the early era of radioactivity. From 1907-1912, Gleditsch worked as Marie Curies assistant in the Laboratoire Curie in Paris on the alleged copper-lithium radioactive transformation and on the radiumuranium ratio, as well as studying chemistry and related subjects at the Sorbonne. Later,in 1913-1914, she worked in Bertram Boltwoods laboratory at Yale University on the half-life of radium. Gleditsch also was concerned with academic opportunities for women, and she became the president of the International Federation of University Women. As a professor, the second female professor in Norway, she initiated a research group on radioactivity at the University of Oslo.     

PLS回归在国际机场服务改进中的应用

为了帮助国际机场在资源有限的情况下,明确服务改进方向从而实现服务质量的改善,本文在现有调查数据的基础上,建立了一个能够明确机场各项服务对“旅客总体满意度”直接影响程度的模型,并给出了运用此模型的诊断思路和方法。鉴于建模目的需要以及对消除多重共线性方法的对比分析,本文选用了偏最小二乘(PLS)回归分析方法。最后对其中一个国际机场进行了诊断,指出了机场服务改进的方向。     

公司治理结构的经理层与企业绩效的实证分析

由于两权分离的特点,经理层在进行经营决策时有可能损害股东和其他利益相关者的利益,影响企业绩效和长期发展。通过模型分析,经理层的激励机制对公司绩效确实具有正向作用。今后应该建立更加积极的薪酬机制,并且实施必要的约束机制。
