关于上海学生考核与选拔的初步思考     

中国致公党上海市委员会课题组  Shen Hong 《教育发展研究》2006,(2):53-58

“和谐社会”的理念,正以其独具的理论和前景魅力吸引着来自世界的目光。建设社会主义和谐社会,教育在其中将发挥极其重要的作用。2005年初,上海市教委委托上海八个民主党派合作进行“和谐上海的教育”决策咨询课题研究。各民主党派抽调或邀请党派内外的骨干力量、科研专家共同参与,历时十个月,按时完成了研究任务。本刊分两期摘要刊发这一课题研究的成果,供相关部门、研究人员参考。  相似文献   

Comparison of high order aberration after conventional and customized ablation in myopic LASIK in different eyes of the same patient   总被引：4，自引：0，他引：4  

Du CX  Shen Y  Wang Y 《Journal of Zhejiang University. Science. B》2007,8(3):177-180

Purpose: To verify whether there exists any difference in higher order aberrations after undergoing myopic LASIK (laser in situ keratomileusis) with conventional ablation and customized ablation in different eyes of the same patient. Methods: This was a prospective randomized study of 54 myopic eyes (27 patients) that underwent LASIK using the Nidek EC-5000 ex-cimer laser system (Nidek, Gamagori, Japan). Topography-guided customized aspheric treatment zone (CATz) was used in the first eye of the patient (study group) and the other eye of the same patient was operated on with conventional ablation (control group). Higher order aberrations [root-mean-square (RMS) in the 5-mm zone] of both groups were observed with the Nidek OPD-Scan aberrometer before and 3 months after LASIK. Preoperative mean refractive error was similar between two eyes of the same patient (t=?0.577, P>0.05). Results: Preoperatively, higher order aberrations (RMS in the 5-mm zone) in the CATz ablation and conventional groups were (0.3600±0.0341) μm and (0.2680±0.1421) μm, respectively. This difference was not statistically significant (t=1.292, P>0.05). Three months after LASIK, higher order aberrations (RMS in 5-mm zone) in the CATz ablation and conventional groups were (0.3627±0.1510) μm and (0.3991±0.1582) μm, respectively. No statistically significant difference was noted between pre- and postoperative higher order aberrations in the CATz group (t=?0.047, P>0.05). However, a statistically significant increase in higher order aberrations was observed after conventional ablation (t=?5.261, P<0.05). A statistically sig-nificant difference was noted in the increase of higher order aberrations after LASIK between groups (t=?2.050, P=0.045). Con-clusion: LASIK with conventional ablation and topography-guided CATz ablation resulted in the same BSCVA (best specta-cle-corrected visual acuity) 3 month after LASIK. Higher order aberrations were increased, but the increase of higher order ab-errations after customized ablation treatment was less than that after conventional ablation.  相似文献   

Superscattering of water wavesOA     

Zijian Qin  Chao Qian  Lian Shen  Xiaoping Wang  Ido Kaminer  Hongsheng Chen  Huaping Wang 《国家科学评论(英文版)》2023,(7):91-97

Inspired by the concept of superscattering in optics,we for the first time theoretically predict and experimentally demonstrate the superscattering phenomenon in water waves.The subwavelength superscatterer is constructed by multi-layered concentric cylinders with an inhomogeneous depth profile.The superscatterer breaks the long-held single-channel scattering limit by several times and thus significantly enhances the total scattering strength.The underlying mechanism originates from the near deg...  相似文献   

In situ electrochemical reconstruction of Sr₂Fe_1.45Ir_0.05Mo_0.5O_6-δ perovskite cathode for CO₂ electrolysis in solid oxide electrolysis cells     

Yuxiang Shen  Tianfu Liu  Rongtan Li  Houfu Lv  Na Ta  Xiaomin Zhang  Yuefeng Song  Qingxue Liu  Weicheng Feng  Guoxiong Wang  Xinhe Bao 《国家科学评论(英文版)》2023,(9):37-45

Solid oxide electrolysis cells provide a practical solution for the direct conversion of CO₂ to other chemicals(i.e.CO),however,an in-depth mechanistic understanding of the dynamic reconstruction of active sites for perovskite cathodes during CO2 electrolysis remains a great challenge.Herein,we identify that iridium-doped Sr₂Fe_1.45Ir_0.05Mo_0.5O_6-δ(SFIrM) perovskite displays a dynamic electrochemical reconstruction feature during CO...  相似文献   

The influence of self-determination in physical education on leisure-time physical activity behavior   总被引：1，自引：0，他引：1  

Shen B  McCaughtry N  Martin J 《Research quarterly for exercise and sport》2007,78(4):328-338

Using a multitheory approach, this study was designed to investigate the influence of urban adolescents' perceived autonomy and competence in physical education on their physical activity intentions and behaviors during leisure time. A transcontextual model was hypothesized and tested. Urban adolescents (N=653, ages 11-15 years) completed questionnaires assessing relevant psychological constructs and moderate to vigorous physical activity and then had their cardiorespiratory fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Based on our structural equation modeling analyses and fit indexes, the transcontextual model adequately fit the data. We concluded that the two theoretical frameworks--SDT and theory of planned behavior--can be integrated to provide an enhanced understanding of the influence of physical education on leisure-time physical activity. The results revealed that perceived autonomy and competence in physical education are interrelated and function as a whole for enhancing leisure-time physically active intentions and behavior.  相似文献

文言文教学也要有整体观念     

张日 《内蒙古师范大学学报(教育科学版)》1998,(5)

阅读的核心是理解,理解要讲整体观念。整体理解即是在阅读中倡导总体感知、总体把握读物,在整体感知、把握的基础上再求局部的推敲、研讨。文言文教学中,释词译句固然是教学的重点,但也不应看成是教学的终极,应给理解,特别是整体理解课文以应有的地位。叶圣陶先生说：“学习课文首先应该是‘通读全文’‘知道文章的大概’”,讲的就是首先要对文章进行整体理解。当然,讲整体理解,并不是否定局部的研读、精读,而是说局部的研读、精读应以整体理解为基础,局部的理解、探求离不开整体的把握,且最终也要回归到整体方面,让文言文阅读…  相似文献
