4-6岁幼儿社会戏剧游戏水平调查研究

本研究以68名幼儿为研究对象，运用《游戏检核表》对其社会戏剧游戏水平进行调查，研究发现：4-6岁幼儿角色扮演、口语交流、互动和同伴支持水平高，游戏时间充分；但物品假装、如何进入游戏小组、问题解决和轮流技能较低。教师应通过明确自身角色、丰富幼儿游戏材料和经验、提升幼儿语言能力和社会交往技能促进幼儿社会戏剧游戏发展。     

我国农业传统文化与后现代农业发展的相关思考

现代农业的发展是以功利性为特征的,受经济目标的逐利影响,正逐渐步入生态困境。后现代农业发展阶段将出现农业生态观的原始回归,这将为我国农业传统文化功能的发挥创造机遇。我国后现代农业发展阶段应重视传统农业文化的诉求,挖掘本土农业文化资源,加强对外引文化的审视,提高农业自我创新能力。     

论20世纪70年代初国际石油权力结构的变迁——对“德黑兰协定”和“的黎波里协定”的考察

20世纪70年代的国际石油危机有着深厚的历史根源,它源于国际石油权力结构的急剧变革。60年代后期开始,随着国际石油市场日趋紧张,产油国的地位日益改善,它们从石油公司获得越来越多的石油权力,其中国际石油公司与产油国签订的"德黑兰协定"和"的黎波里协定"发挥了至关重要的作用,是产油国能够针对西方国家使用减产、禁运和提价等石油武器的前提条件。     

Parental income and the fruits of labor: Variability in homework efficacy in secondary school

Research in the sociology of education has shown that noncognitive traits are important predictors of educational outcomes and a mechanism of the intergenerational transmission of status. However, previous research on this topic typically posits that there is a constant effect of these traits with variable prevalences of these traits by socioeconomic status. Using time spent on homework as an example, I analyze income-based heterogeneity in homework efficacy, defined as the individual effect of study time on academic achievement, using a national U.S. probability sample of secondary students. Higher income students gain more knowledge from their homework time than their counterparts in all grades and all subjects except history, with greater group differences for math than for science and reading. These results are confirmed by models accounting for time-invariant unobserved heterogeneity in the 8th–10th, but not 10th–12th, grade windows. These results imply that increases in the amount of homework assigned may increase the socioeconomic achievement gap in math, science, and reading in secondary school.     

美国大学社会服务的“大学社区参与”模式评析

"大学社区参与"是20世纪90年代以来美国兴起的新型大学社会服务模式。这一模式在大学与社区的合作伙伴关系基础上,以社区需求和社会发展为动力,旨在推进大学教学、科研与服务功能的综合发展,具有学术性、综合性、互惠性、公共性等特征。大学领导层、组织机构、教师参与、组织文化以及大学与社区的权力关系等因素共同决定着"大学社区参与"模式的运行状况。"大学社区参与"模式对我国大学社会服务的现代发展具有借鉴意义。     

《贞观政要》官德保障机制论要

《贞观政要》继承和发展了儒学政治哲学的人性理论。其官德保障机制体现在内修与外治两个方面,一则从非制度的内在层面强调官吏通过思、慎和学的途径修身养德,二则从制度的外在层面加强旨在预防、考课与奖惩官员的吏治建设。体现自律与他律、儒学政治哲学与法家政治理念的统一,完善了中国传统政治外儒内法的基本模式。     

Estimation and goodness-of-fit procedures for Farlie–Gumbel–Morgenstern bivariate copula of order statistics

In this study, we provide the Farlie–Gumbel–Morgenstern bivariate copula of rth and sth order statistics. The main emphasis in this study is on the inference procedure which is based on the maximum pseudo-likelihood estimate for the copula parameter. As for the methodology, goodness-of-fit test statistic for copulas which is based on a Cramér–von Mises functional of the empirical copula process is applied for selecting an appropriate model by bootstrapping. An application of the methodology to simulated data set is also presented.     

India's demand for international reserve and monetary disequilibrium: Reserve adequacy under floating regime

The main aim of this study is to investigate India's demand for international reserve by focusing on the role of national monetary disequilibrium and to present new benchmarks for assessing the adequacy of international reserves. We assessed India's position in terms of reserve adequacy and found that India is well placed and has sufficient stock of international reserves to meet the minimum adequacy requirements. Also, the results reveal that the central bank is holding substantial excess reserves and the related opportunity cost (1.5% of GDP) appears to be quite considerable. Further, the estimates of reserve demand function suggest that scale of foreign trade, uncertainty and profitability considerations play significant role in determining India's long-term reserve demand policies. More importantly, validating the monetary approach to balance of payment, our results show that national monetary disequilibrium does play a crucial role in short-run reserve movements. An excess of money demand (supply) induces an inflow (outflow) of international reserves with an elasticity of 0.56 which also implies that Reserve Bank of India responds to correct the domestic money market disequilibrium; and did not just leave it completely on the mercy of reserve inflows.
