论富布赖特《旧神话与新现实》演讲的历史作用

1964年3月25日,美国参议院外交委员会主席富布赖特在参议院发表了针对中国问题的《旧神话与新现实》的著名长篇演讲,目的是激励美国公众自由思考和讨论美国僵硬过时的对华政策,进而推动国内对华舆论朝着积极的方向进一步发展,并且建议美国在对华政策中增加灵活性。     

Graphical Techniques for Selecting Explanatory Variables for Time Series Data

Bayesian model building techniques are developed for data with a strong time series structure and possibly exogenous explanatory variables that have strong explanatory and predictive power. The emphasis is on finding whether there are any explanatory variables that might be used for modelling if the data have a strong time series structure that should also be included. We use a time series model that is linear in past observations and that can capture both stochastic and deterministic trend, seasonality and serial correlation. We propose the plotting of absolute predictive error against predictive standard deviation. A series of such plots is utilized to determine which of several nested and non-nested models is optimal in terms of minimizing the dispersion of the predictive distribution and restricting predictive outliers. We apply the techniques to modelling monthly counts of fatal road crashes in Australia where economic, consumption and weather variables are available and we find that three such variables should be included in addition to the time series filter. The approach leads to graphical techniques to determine strengths of relationships between the dependent variable and covariates and to detect model inadequacy as well as determining useful numerical summaries.

“前”字所反映的汉民族的时间认知

汉语中存在大量的"前"字所组成的时间词。这些时间词反映出汉民族的时间是空间的认知,表现出汉语空间—时间隐喻的直线性模式。这其中又存在两套时间是空间的隐喻系统——"时间移动"隐喻系统和"自我移动"隐喻系统,依据两个系统绝大部分时间词的语义已"脱离语境化",但少数时间词的语义并没有完全固化,需要认知语境的参与,进行认知推理,才能获取其意义。     

我国房地产价格发展趋势研究

 本文从房地产价格的相关理论出发，主要从房地产需求、房地产供给、房地产金融和房地产宏观调控等角度对影响房价的因素进行了分析，并从实证角度分析了各因素对房价的影响。本研究运用近10年房地产价格季度数据和时间序列模型对房地产价格发展趋势进行预测，最后提出房地产价格发展预警和稳定房价的建议。

Use of time and preferences for time allocation among urban,employed, married women

This study examines the relationship between employed wives' preferences for household production time, employment time, leisure, and their actual time use. A random sample of 235 employed, married women estimate their time use on an average weekday and weekend day in 13 activities and indicate their preferences for time in those activities. Hierarchical multiple regression procedures are used to examine the relationships between actual and preferred time use. Weekday employment time is not related to preferences for more or less time in household production but wives allocating more time to employment want to spend less time at that employment and more time in leisure. Weekend employment time is related to preferences for more time in leisure, child care, and other household work. Time spent performing household work is not related to preferences for more or less time in any activity except the desire for more leisure time on weekends.Ann Renigar Hiatt is Assistant Professor in the Department of Human Services, College of Education and Allied Professions at the University of North Carolina at Charlotte, Charlotte, NC 28223. Her research interests include employed women's time allocation, time pressures, and use of time management strategies. She received her Ph.D. from the University of North Carolina at Greensboro.Deborah D. Godwin is Associate Professor in the Department of Housing and Consumer Economics at the University of Georgia, Athens, GA 30602. Her research has focused on husbands' and wives' time allocation to household production, the effects of women's employment on family economic functioning, and family financial management. She received her Ph.D. from the University of North Carolina at Greensbore.

大学生心理控制源对时间管理倾向的影响

目的：探讨大学生心理控制源对时间管理倾向的影响,为高校教育教学工作提供参考和依据。方法：采用黄希庭编制的“青少年时间管理倾向量表”和罗特编制的“内在—外在心理控制源量表”对208名大学生进行测试。结果：大学生心理控制源在性别和年级方面不存在显著的差异,时间管理倾向在性别和年级方面存在显著的差异,女生在时间管理方面要好于男生,大一学生对时间的管理要好于其他年级的学生;大学生心理控制源与时间管理倾向及时间价值感、时间监控观呈显著正相关;内控型大学生在时间管理总体水平及时间监控观、时间效能感上均显著高于外控型大学生;回归分析表明,心理控制源对时间管理总体水平及时间价值感、时间监控观均具有显著的预测作用。结论：大学生心理控制源对其时间管理倾向具有显著影响,可以通过有针对性地归因训练来提高大学生的时间管理水平。
