关于民办高校大学生思政课可接受度的调查与研究

如何提高民办高校大学生思政课的可接受度,是高校思政课长期关注的重大课题。本文就当前民办高校大学生思政课教学接受状况进行了调研与系统分析,并在此基础上提出了提高民办高校思政课可接受度的对策。     

Illustrating the importance of Austrian business cycle theory: A reply to Murphy,Barnett, and Block; A call for quantitative study

Murphy et al. (2009) criticize Young’s (2005) test of Austrian business cycle theory (ABCT) using US industry-level quarterly job reallocation data and the federal funds rate as a monetary policy indicator. I argue that not only are Murphy et al.’s specific criticisms misguided; more importantly, they all but completely rule out the type of empirical study that Young (2005) advocates: specifically, one that (1) is quantitative and distinguishes between statistical and economic significance and (2) attempts to exploit a hypothesis that is both a prediction of ABCT and not a prediction of competing monetary theories of the cycle. I argue that empirical studies embodying (1) and (2) are critical to ABCT as a research program. Furthermore, I review the existing econometric studies of ABCT from the last 10 years and conclude that there is much room for improvement along these lines.     

菜籽油生物柴油技术经济评价——基于全生命周期评价方法

采用全生命周期评价方法,对菜籽油制生物柴油的二氧化碳排放量和经济性进行了评估,旨在说明用菜籽油生产生物柴油对环境的影响及其经济价值。结果表明:在用菜籽油生产生物柴油的全生命周期过程中,排放入大气中的二氧化碳量远低于从大气中吸收的二氧化碳量,油菜籽制生物柴油是一种环境友好的燃料;就经济性而言,菜籽油制生物柴油的生产成本较高,每吨约高出0#柴油3178.2元,生物柴油的商业化应用尚需等待原料成本的降低。     

我国畜产品价格波动分析——基于ARCH类模型

运用ARCH类模型对我国主要畜产品的价格波动率进行了分析。结果表明:牛肉、羊肉和鸡肉的价格波动具有显著的波动积聚性,鸡蛋价格波动没有显著的异方差效应;除牛肉市场外,羊肉和鸡肉市场不具有高风险、高回报的特征;猪肉、牛肉、羊肉和鸡肉的价格波动没有非对称性。认为应在畜产品市场出现大的价格波动时及时采取平抑措施,且政府需规范畜产品市场秩序、完善畜产品市场制度。     

Investment opportunities and dividend omissions

This study examines the market's reaction to dividend omission announcements and finds that if dividends are skipped to preserve cash for good investments, investors do not necessarily regard the omission as negative information. Markets penalize firms for dividend omissions only in the absence of a good stream of investments. In addition, the positive relation between investment opportunity and abnormal stock returns around the announcements is stronger when the level of information asymmetry between management and the rest of the market participants is low. Additional tests reveal that good omitters overcome underperformance faster in the post period. Overall, the results suggest that financial markets interpret differently the information conveyed in the announcement of dividend omission depending on the firm's future prospects.     

Deriving joint space positioning maps from consumer preference ratings

Joint space multidimensional scaling maps are often utilized for positioning analyses and are estimated on survey samples of consumer preferences, choices, considerations, or intentions so as to provide a concise spatial depiction of the competitive landscape including relevant dimensions or attributes, competing brands, and consumers in the same joint space representation. Care has to be given concerning the underlying scale properties of such survey data so as not to distort the resulting joint space positioning map. We present a new joint space multidimensional scaling procedure for positioning analyses for displaying the structure in such survey data when such common ordered successive category measurement scales such as Likert, Edwards, semantic differential, etc., are employed. We present the technical details of this stochastic ordered preference multidimensional scaling vector model as well as the maximum likelihood estimation-based algorithm devised for parameter estimation. Favorable comparisons are made with several existent multidimensional scaling methods in representing the internal structure for such data in marketing positioning studies. An actual commercial positioning application concerning large sports utility vehicles consideration to buy judgments is presented with predictive validation comparisons with other multidimensional scaling joint space procedures.     

用自然的语言接近微积分——以James Stewart所著的《微积分》为例

长期以来,微积分始终是数学教育改革中最活跃的领域之一。美国的微积分改革使得美国的微积分教学充满了活力,它注重本质,发现能帮助学生获得对微积分思想深刻理解的创造性方法。通过分析美国微积分的主流教材,即James Stewart所著的《微积分》教材,并与我国微积分教材中的极限理论、微分学和积分学部分进行了比较研究,根据比较研究的结论,对我国微积分教学提出了若干建议。

海南省县域经济竞争力的思考

加快县域经济发展是建设社会主义新农村的重要任务,是解决"三农"问题的根本。通过县域经济的发展,为新农村建设提供一个物质前提。本文阐述了海南省县域经济发展的现状与差异,对海南省县域基本竞争力进行评价分析,分析了海南省县域经济发展存在的问题,对提升海南省县域经济的发展提出了思路与对策。     

论旅游线路的文化品味提升:基于非物质文化遗产的视角——以珠三角为例

通过广州、深圳、佛山、东莞和中山五城市旅游线路的调查,非物质文化遗产作为一种较高级别的旅游资源未得到旅行社的足够重视。针对国内旅游线路缺乏创新,欠缺文化内涵的现状,对旅行社的旅游线路进行改造,融入非物质文化遗产的项目,旨在通过提升线路文化品味的同时促进非物质文化遗产的传承和发展。
