A Decision Model for the Robot Selection Problem Using Robust Regression*

Industrial robots are increasingly used by many manufacturing firms. The number of robot manufacturers has also increased with many of these firms now offering a wide range of models. A potential user is thus faced with many options in both performance and cost. This paper proposes a decision model for the robot selection problem. The proposed model uses robust regression to identify, based on manufacturers' specifications, the robots that are the better performers for a given cost. Robust regression is used because it identifies and is resistant to the effects of outlying observations, key components in the proposed model. The robots selected by the model become candidates for testing to verify manufacturers' specifications. The model is tested on a real data set and an example is presented.     

论素质教育的价值基础及其自由意蕴--教育价值论视阈下的素质教育新探

素质教育是一种建构性的教育理想,是价值范畴,而非科学的事实性范畴。为此,我们应从教育价值论的视角来给素质教育定位。理想的教育价值取向就是使教育对所有评价主体有价值,因惟有自由才是人所共有的价值理想,所以,素质教育要成为一种理想教育,它就必须遵循自由这个价值取向,要以促进自由为目的。简言之,自由教育是素质教育的价值方向。

论"新帝国主义"的实质、根源及影响

“新帝国主义”的内涵包括两个层面:新帝国主义理论以及根据这个理论制定的在世界范围内建立一种“新帝国”的全球霸权政策。它要用美英的价值观改造世界,在全球范围内建立一种美英统治下的新秩序。从实质和根源来看,“新帝国主义”是在冷战后垄断资本加速向外扩张的背景下产生的,是帝国主义发展到国际垄断资本主义阶段的表现形式,它与国际垄断资本主义的发展密切相关。从现状和趋势来看,“新帝国主义”对国际关系和世界格局都产生了严重的消极影响,必然遭到世界进步人类的批评和反对,它最终是要失败的。     

司马迁经济思想的深层剖析

迄今为止,对司马迁的经济思想的研究明显不足。文章认为,从经济思想史的角度来看,司马迁在其不朽之作《史记》中将《平准书》、《河渠书》列入八书,并为古代的经济思想家和大工商业者专辟《货殖列传》,这就为中国的史学创造了一条必须记载经济活动的范例。本文从司马迁对商业都市经济的描绘及其重商观念、财富观念、流通观念、经营理论、货币理论等方面对司马迁的经济思想进行了深度阐析。     

和谐社会视野下高校德育价值

From low to high fertility in Sulawesi (Indonesia) during the colonial period: explaining the 'first fertility transition'

This paper examines the past transition from low to high fertility which, in Indonesia as elsewhere, preceded the return to lower birth rates. Data from two parts of the island of Sulawesi where fertility rose during the colonial period are used to explain both why it rose, and why it was originally low. Economic conditions, it is argued, were the most important factors, affecting fertility via the supply of income and the demand for labour. Two schematic models of the 'first fertility transition' are proposed. In areas with low population densities and area-extensive forms of agriculture responsive to commercial stimuli, birth rates rose as the growth of commerce raised levels of prosperity, facilitated marriage, and undermined institutions such as debt-slavery which had previously acted to restrict marital fertility. In densely populated areas with labour-intensive agriculture and heavy state taxation in labour, fertility rose in response to demands for women's (and possibly child) labour that did not necessarily lead to gains in income.
