Teaching autonomy is an important power of teachers as professionals and also a key factor affecting instructional *** on the relevant data of the Teaching and Learning International Survey(TALIS)2018,this study analyzes teachers’teaching autonomy and its effect on instructional *** finds that,firstly,as compared to those in the countries of the Organization for Economic Co-operation and Development(OECD),teachers in Shanghai,China,have greater teaching autonomy,but there is still room for improvement in this *** have sufficient autonomy in determining the instructional content and disciplining students,but not in assessing students’***,increasing the teaching autonomy in Shanghai can significantly improve instructional *** their autonomy in assessing students’learning has the greatest effect on improving instructional quality,while increasing the autonomy in choosing teaching methods has the least effect,which is culturally different from the situation in OECD ***,the influence of teaching autonomy on instructional quality is positively moderated by teaching efficacy,which means that teachers need to have the“ability”in addition to the“autonomy.”Based on this,suggestions are also made.

OBJECTIVE： To assess the efficacy of acupuncture combined with vitamin B12 acupoint injection versus acupuncture alone to reduce incomplete recovery in patients with Bell＇s palsy. DATA RETRIEVAL： A computer-based online retrieval of Medline, Web of Science, CNKI, CBM databases until April 2014 was performed for relevant trials, using the key words ＂Bell＇s palsy or idiopathic facial palsy or facial palsy＂ and＂acupuncture or vitamin B12 or methylcobalamin＂. STUDY SELECTION： All randomized controlled trials that compared acupuncture with acupuncture combined with vitamin B12 in patients with Bell＇s palsy were included in the me- ta-analysis. The initial treatment lasted for at least 4 weeks. The outcomes of incomplete facial recovery were monitored. The scoring index varied and the definition of healing was consistent. The combined effect size was calculated by using relative risk （RR） with 95% confidence interval （C/） using the fixed effect model of Review Manager. MAIN OUTCOME MEASURES： Incomplete recovery rates were chosen as the primary outcome. RESULTS： Five studies involving 344 patients were included in the final analysis. Results showed that the incomplete recovery rate of Bell＇s palsy patients was 44.50% in the acupuncture combined with vitamin B12 group but 62.57% in the acupuncture alone group. The major acupoints were Taiyang （EX-HN5）, Jiache （ST6）, Dicang （ST4） and Sibai （ST2）. The combined effect size showed that acupuncture combined with vitamin B12 was better than acupuncture alone for the treatment of Belrs palsy （RR = 0.71, 95%CI： 0.58-0.87; P = 0.001）, this result held true when 8 patients lost to follow up in one study were included into the analyses （RR = 0.70, 95%CI： 0.58-0.86; P = 0.0005）. In the subgroup analyses, the therapeutic effect in patients of the electroacupuncture subgroup was better than in the non-electroacupuncture subgroup （P = 0.024）. There was no significant dif- ference in the incomplete recovery rate by subgroup analysis on dru

The panel dataset which covered the socio-economic data of 31 provinces （municipalities and autonomous region） in China from 2000-2007 was used to do empirical analysis on the effect of abolishing agricultural taxes on farmers＇ income by referring to the fixed effect estimation method. It found that the abolition of agricultural taxes increased farmer＇s net income per capita by 2%. Combining with the results of empirical analysis, related policy suggestions were put forward to increase farmers＇ income.

[Objective] This study aimed to survey the effect of insecticide use intensity on the resistance of rice stem borer in South China. [Method] The data includes 19 counties from Guangdong Province and Guangxi Province from 1991 to 2010. A fixed effect model was established to evaluate the effect of insecticide use intensity on the resistance of rice stem borer. [Result] The regression results suggest that one-period lagged total number of insecticide sprays has significant effect on the infestation level of rice stem borer. [Conclusion] Although rice stem borer is a migratory rice pest, insecticide use intensity has significant effect on the resistance level of rice stem borer in South China.

[Objective] This study aimed at revealing the effect of insecticide spray on the infestation level of rice planthopper in large spatial scale and in long term. [Method] The data set included twenty counties from 1991 to 2009. Therefore fixed effect model was established to evaluate the effect of insecticide spray on the infes- tation level of rice planthopper. The OLS method was used to estimate the fixed ef- fect model. [Result] The regression results of the fixed effect model suggested that one period lag insecticide spray had a significant effect on the infestation level of rice planthopper. [Conclusion] Even though rice planthopper is a migratory rice pest, insecticide spray has a significant effect on the infestation level of rice planthopper in large spatial scale and in long term.

大规模抽样调查多采用复杂抽样设计，得到具有分层嵌套结构的调查数据集，其中不可避免会遇到数据缺失问题，针对分层结构含缺失数据集的插补策略目前鲜有研究。本文将Gibbs算法应用到分层含缺失数据集的多重插补过程中，分别研究了固定效应模型插补法和随机效应模型插补法，进而通过理论推导和数值模拟，在不同组内相关系数、群组规模、数据缺失比例等情形下，从参数估计结果的无偏性和有效性两方面，比较不同方法的插补效果，给出插补模型的选择建议。研究结果表明，采用随机效应模型作为插补模型时，得到的参数估计结果更准确，而固定效应模型作为插补模型操作相对简便。在数据缺失比例较小、组内相关系数较大、群组规模较大等情形下，可以采用固定效应插补模型，否则建议采用随机效应插补模型。

研究旅游服务贸易出口的决定因素可以帮助寻求当下中国服务贸易巨额逆差的解决方法，从而为政府制定相关政策提供理论基础。然而现有文献中，尚且无人以中国的省级数据作为研究对象，进行旅游服务进出口方面的实证研究。我们的论文填补了这个空缺，利用固定效应对2004-2013年中国各省对世界各国旅游服务贸易出口的平板数据进行综合、全面的回归分析。研究结果表明，中国的旅游出口需求被验证与文献中研究的其他国家与地区有着潜在一致的规律，其中旅游目的地的繁荣程度、游客来源地国家的人口总量、两国的相对价格、两国是否签订自由贸易协定等等变量对旅游服务出口有着尤其显著的影响，与传统重力模型的一般性结论相一致。
