焦虑的诱发因素及调控方法--以体操教学为例的研究

国内外心理学对学生的焦虑与运动成绩的相关研究已成为一个专门的课题。针对焦虑对学生体操技术掌握的影响，运用运动心理学有关理论对大学生体操教学中的焦虑诱发因素进行问卷调查，归纳了体操教学中诱发学生焦虑过度的原因，并对其主要影响因素进行分析，提出了控制学生的适宜焦虑水平的方法。     

义务教育乡镇管理体制评析

由于乡镇的财力单薄,管理水平偏低,管理心态失衡,乡镇政府难以有效管理本乡镇义务教育。改革义务教育乡镇管理体制,必须废除监护人直接支付的筹资方式,实行税收统筹分拨的筹资方式,建立省、县、乡三级义务教育管理体制,从经济上保证儿童受教育的权利。

Sampling design proportional to order statistic of auxiliary variable

The sampling designs dependent on sample moments of auxiliary variables are well known. Lahiri (Bull Int Stat Inst 33:133–140, 1951) considered a sampling design proportionate to a sample mean of an auxiliary variable. Sing and Srivastava (Biometrika 67(1):205–209, 1980) proposed the sampling design proportionate to a sample variance while Wywiał (J Indian Stat Assoc 37:73–87, 1999) a sampling design proportionate to a sample generalized variance of auxiliary variables. Some other sampling designs dependent on moments of an auxiliary variable were considered e.g. in Wywiał (Some contributions to multivariate methods in, survey sampling. Katowice University of Economics, Katowice, 2003a); Stat Transit 4(5):779–798, 2000) where accuracy of some sampling strategies were compared, too.These sampling designs cannot be useful in the case when there are some censored observations of the auxiliary variable. Moreover, they can be much too sensitive to outliers observations. In these cases the sampling design proportionate to the order statistic of an auxiliary variable can be more useful. That is why such an unequal probability sampling design is proposed here. Its particular cases as well as its conditional version are considered, too. The sampling scheme implementing this sampling design is proposed. The inclusion probabilities of the first and second orders were evaluated. The well known Horvitz–Thompson estimator is taken into account. A ratio estimator dependent on an order statistic is constructed. It is similar to the well known ratio estimator based on the population and sample means. Moreover, it is an unbiased estimator of the population mean when the sample is drawn according to the proposed sampling design dependent on the appropriate order statistic.     

构建科学的教坛新秀评选体系

青年教师是高校教学科研的主力军,培养和造就一批高素质的青年教师队伍是推进高校素质教育的一项重要的战略任务,但他们中有许多人存在人文精神缺失及修养不足的问题,对高校的改革与发展产生了消极影响。为切实加强青年教师队伍建设,高校在广大青年教师中开展“教坛新秀”评选活动,以此激励广大青年教师的荣誉感和责任感,促进师德水平和教育教学质量水平的提高,意义深远。从评选理念出发,对教坛新秀的评选指标、评选条件、评选方法做了微观定位,以期为构建科学的教坛新秀评选体系提供参考。     

Almost Consistent Estimation of Panel Probit Models with “Small” Fixed Effects

We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small Tand large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators differ w.r.t. the choice of instruments and whether they use trimming to reduce the bias or not. In a Monte Carlo study, we compare these estimators with pooled probit and conditional logit estimators for different data generating processes. The results show that the proposed estimators outperform these competitors in several situations.
