浅谈问卷调查中非抽样误差的控制

问卷调查是采用抽样调查方式，利用设计好问题的表格，收集数据资料并对其进行统计分析的一种调查方法，但问卷调查的结果常常会受到抽样误差和非抽样误差的影响，尤其是后一般难以控制。因此，研究各个阶段非抽样误差的成因，采取不同措施分别加以控制就十分必要。     

试论1895～1898年康有为改良理论的失误

戊戌变法的惨败,与1895~1898年康有为改良理论的失误直接相关。康有为改良理论源于孔子学说,改良理论模式采取激进主义,改良必要性植根于中国战败的现实及其严重后果的预设,改良的主要依靠力量寄望于维新派人士乃至皇帝一人。如此诸多失误,为改良运动的最终失败埋下了隐患。     

Estimating Standardized SEM Parameters Given Nonnormal Data and Incorrect Model: Methods and Comparison

When both model misspecifications and nonnormal data are present, it is unknown how trustworthy various point estimates, standard errors (SEs), and confidence intervals (CIs) are for standardized structural equation modeling parameters. We conducted simulations to evaluate maximum likelihood (ML), conventional robust SE estimator (MLM), Huber–White robust SE estimator (MLR), and the bootstrap (BS). We found (a) ML point estimates can sometimes be quite biased at finite sample sizes if misfit and nonnormality are serious; (b) ML and MLM generally give egregiously biased SEs and CIs regardless of the degree of misfit and nonnormality; (c) MLR and BS provide trustworthy SEs and CIs given medium misfit and nonnormality, but BS is better; and (d) given severe misfit and nonnormality, MLR tends to break down and BS begins to struggle.

Exploring connections among reading,spelling, and phonemic segmentation during first grade

Exploratory data analysis was used to examine changes in individual reading and spelling patterns during first grade. Subjects were from classrooms receiving, on average, 45 minutes compared to 15 minutes of daily letter-sound instruction. Subjects spelled and read 60 words in October, February, and May, and deleted sounds from spoken words. Spelling and reading responses progressed from nonphonetic, to phonetic, to correct. Additionally, knowledge of a word's spelling informed its reading, while the converse was less apparent. Finally, those slow to improve in phoneme deletion were also slow to spell and read phonetically, especially among subjects receiving less instruction in letter-sound relations.
