扩张主义文化与文化扩张

美国的扩张主义是一个永恒的话题。建立之初开始的近一个世纪的领土扩张，19世纪下半叶开始的向美洲大陆和海外的经济扩张以及20世纪在全球的化扩张，无不体现了美国是一个不断向外扩张的国家，当然这一切都与其经济政治及安全的现实利益有关。本主要从历史、宗教和哲学这几个角度去分析扩张主义的化渊源，并对美国日渐重视的化扩张进行探讨。作认为在国际格局多极化和化多元化的环境下，化霸权主义是不得人心的，只有化间的平等交流才有利于各国共同发展。     

卡伯拉尔远航印度意义初探

1500-1501年卡伯拉尔率葡萄牙舰队远航印度,堪称地理大发现第一阶段仅次于三大航行的第四大航行。这次远航经过了欧美非亚四大洲,往返行程5.5万公里。卡伯拉尔远航开创了发现、殖民南美大陆和巴西的进程,重新发现了世界第四大岛马达加斯加。从此葡萄牙人在印度辟建商站立足插手,创建商业殖民帝国;同时开始在印度洋上打击摩尔人—穆斯林,由此开辟了反击反包围摩尔人—穆斯林的新战线,实现了当初的一个战略意图,问鼎印度洋霸权。     

论假释的扩大适用

中国是世界上假释适用率较低的国家之一 ,这种状况不仅抑制了假释功能的有效发挥 ,而且给监管工作和罪犯顺利回归社会带来了一系列负面影响。为了进一步发挥假释制度的功能 ,必须加快假释的扩大适用     

网络零售配送系统最优运作成本的分析

针对配送运作成本关键部分棗平均运距作出的估计,在车辆路径问题渐进最优理论的基础上,建立了一个平均运作成本最优的规划模型,从经济的角度对运作策略作了简要分析。与其他规划模型不同,新建模型考虑了平均水平的概率特性及众多实际因素,因而具有较好的实用性。     

Gini’s nuclear family

The purpose of this paper is to justify the use of the Gini coefficient and two close relatives for summarizing the basic information of inequality in distributions of income. To this end we employ a specific transformation of the Lorenz curve, the scaled conditional mean curve, rather than the Lorenz curve as the basic formal representation of inequality in distributions of income. The scaled conditional mean curve is shown to possess several attractive properties as an alternative interpretation of the information content of the Lorenz curve and furthermore proves to yield essential information on polarization in the population. The paper also provides asymptotic distribution results for the empirical scaled conditional mean curve and the related family of empirical measures of inequality.      

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.
