An axiomatic approach to \boldsymbol{\varepsilon}-contamination

Summary.  Suppose that an economic agent is 100% certain that uncertainty she faces is characterized by a particular probability measure, but that she has a fear that, with 100% chance, her conviction is completely wrong and she is left perfectly ignorant about the true measure in the present as well as in the future. This situation is often called -contamination of confidence. The purpose of this paper is to provide a simple set of behavioral axioms under which the decision-makers preference is represented by the Choquet expected utility with the -contamination of confidence.Received: 25 November 2002, Revised: 15 November 2004, JEL Classification Numbers:   D81.

2＋1教学模式转变下思政课教法改革思考

思政课在高职院校的教学中与本科院校的教学特点不同,在高职院校培养“应用型人才”的目标下,2＋1教学模式的转变是整体的趋势,在2＋1教学模式下,思政课教学可以分为理论教学与实践教学两个部分,在理论教学中可以采用启发式教学法、讨论式教学法、辩论式教学法、案例式教学法、演讲式教学法、角色互挟式教学法、专题式教学法;在实践教学中可以采用实地考察法、社会调查法、工作实践法,从而提高教学的实际效果。     

单矿物及地球化学特征浅析——以内蒙古鄂温克旗头道桥地区糜棱岩为例

头道桥糜棱岩是以塑性变形为主的韧性剪切带,形成了糜棱岩、碎裂岩系列,该糜棱岩带中糜棱岩的原岩均为花岗岩,该韧性剪切带中的糜棱岩化花岗岩、花岗质初糜棱岩以及花岗质糜棱岩的单矿物化学特征和岩石地球化学特征与岩石变形强度增大和退变质作用增强有着密切的关联,他们都表现出了一定的规律性。     

大学生文化价值观及其班级旅游研究

文化价值观是一群人认为有益的、正确的或有价值的信条或特点。这是一个受年代作用的概念,在不同的年代有着不同的价值,而价值观的确立,属于自然人本身的认可和衡量,一个人经历的年代不同,价值观也不相同,文化价值观也是一样。本文对青少年旅游者(尤其是大学生)的文化价值观进行定性探讨,在此基础上对大学生班级旅游情况进行调查分析,在大学生文化价值观基础上开展的大学生班级旅游这个市场的现状、特色、问题等方面的研究。     

Stock prices,production and interest rates: Comparison of three European countries with the USA

This paper investigates the relationships between stock returns, changes in production, and changes in interest rates in three European countries: France, Germany, and the United Kingdom. The results obtained using annual data are much more conclusive than those obtained using quarterly data. Stock returns are affected by current changes in interest rates and by future changes in production. The dependence on changes in interest rates seems to be higher than on changes in production. Furthermore, the influence of future changes in production on stock returns diminishes substantially when contemporaneous changes in interest rates are taken into account. With reference to these points, the European markets behave in a similar fashion, but are in sharp contrast with the U.S. market.I am very grateful to Kay Davidson, Patric Hendershott and two anonymous referees for useful comments and suggestions. I am solely responsible for all remaining errors.     

20世纪30年代专科以上学校毕业生就业训导班研究

20世纪30年代前期,专科以上学校毕业生失业严重。在学生运动风起云涌之际,设立专科以上学校毕业生就业训导班,被国民政府赋予解决专科以上学校毕业生就业问题的重大使命。就业训导班声势大、力量强、目标明确,部分反映了国民政府试图纠正专科以上学校毕业生就业问题的努力。然而该班的设立因被动、临时、人数有限,且并不触及就业问题的根本,而成为国民政府安抚学生和社会情绪的又一项权宜之计。
