法国教师教育的改革现状及其借鉴     

郑婉 《北京教育学院学报》2011,(5):35-39

法国于1989年着手立法并全面革新师资培养的体制,以推动中小学教师合流及师资培育管道多元化的新制。教师培训学院（les instituts universitaires de formation des maltres,简称IUFM）于1991年诞生。随着教师培训学院的建立,到2005年提出将教师培训学院并入大学,再到2010年末起正式推动实施教师资格硕士化方案,这20年来法国教师教育经历了一场制度上和教育上的变革。  相似文献   

城市农民工就业培训问题实证研究——基于对江苏省常州市302位农民工的调查与分析     

黄瑞玲  李南  王碗 《职业技术教育》2011,32(7)

根据302份调查问卷数据,具体分析农民工入城就业情况与参与技术培训情况,结果显示,城市农民工就业情况堪忧,参与职业技术培训比率低,效果差。他们期待由政府和企业承担培训费用,渴盼以短期、休息时间为主,采取在职学习和现场学习等教学模式,期望除了就业单位培训外,还对政府行为寄予厚望。因此,有关部门应完善农民工就业促进机制,建立农民工职业技术培训长效机制。  相似文献   

现代汉语二合复句中分句语气异类组配的倾向性研究     

万光荣  储泽祥 《暨南大学华文学院学报》2011,(4):64-71

现代汉语二合复句内分句语气同类组配是主体,异类组配是次要的。前后分句语气异类组配的使用频率具有一定的倾向性：陈述与疑问／祈使／感叹的组配〉疑问／祈使／感叹之间的两两组配;陈述＋疑问／祈使／感叹〉疑问／祈使／感叹＋陈述。陈述语气与疑问／祈使／感叹共享特征的数量都多于疑问、祈使、感叹两两语气之间共享特征的数量,因此前者是优势组配。疑问／祈使／感叹居前时通常要满足三个条件,居后时不受此限制,因此疑问／祈使／感叹居后是优势组配。  相似文献   

国内外政府数据开发利用的进展及对我国的政策建议          下载免费PDF全文

宋卿清  曲婉  冯海红 《中国科学院院刊》2020,35(6):742-750

近年来,大数据浪潮兴起,大数据产业保持高速发展态势,大数据应用推进势头良好。政府数据作为价值密度高、涉足广度宽的数据资源,已成为各国争相创新开发的重要资产。但是长期以来,关于政府数据开发利用的理论研究却被忽视,如何科学有效地进行政府数据开发和利用已成为当前需要迫切关注的问题。文章系统总结了当前主要发达国家政府数据开发利用的政策措施和探索实践,以及通过梳理分析我国政府数据开发利用的政策体系和发展现状,尝试构建政府数据开发利用的过程机制模型,并提出:加强顶层立法,落实制度保障;扩大数据来源,提升数据质量;统一汇聚开放,深化行业应用;确立认证许可,明晰授权机制;创新开发模式,明确收益分配;推动试点先行,探索可行经验;强化技术支撑,保障数据安全等政策建议,以期为进一步推动政府数据开发利用提供决策参考。  相似文献   

Equatorial aurora: the aurora-like airglow in the negative magnetic anomaly     

Fei He  Yong Wei  Weixing Wan 《国家科学评论(英文版)》2020,7(10):1606

The most fantastic optical phenomena in the Earth''s upper atmosphere are the auroras. They are highly informative indicators of solar activity, geomagnetic activity, upper atmospheric structures and dynamics, and magnetospheric energetic particles. An area where the geomagnetic field differs significantly from the expected symmetric dipole, such as at the South Atlantic Anomaly, where the magnetic field intensity is low, gives rise to stronger precipitation of energetic particles into the upper atmosphere. Impact excitation and the subsequent airglow emissions exhibit aurora-like dynamic signatures. Nomenclatures of nonpolar aurora or equatorial auroras are similar to those used with the polar auroras owing to their similar excitation mechanisms. This paper provides an overview of the knowledge and the challenges concerning auroral activity at the South Atlantic Anomaly, or more generally, at the negative magnetic anomaly. We emphasize systematic investigation of the equatorial auroras to reveal the temporal and spatial evolution of the magnetic anomaly and the behaviour of energetic particles in near-Earth space.  相似文献   

Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43].  相似文献

Why super sandstorm 2021 in North China?     

Zhicong Yin  Yu Wan  Yijia Zhang  Huijun Wang 《国家科学评论(英文版)》2022,9(3)

Severe sandstorms reoccurred in the spring of 2021 after an absence for more than 10 years in North China. The dust source area, located in Mongolia, suffered destructive cooling and warming in early and late winter, which loosened the land. A lack of precipitation, excessive snow melt and strong evaporation resulted in dry soil and exiguous spring vegetation. A super-strong Mongolian cyclone developed on the bare and loose ground, and easily blew and transported large amounts of sand particles into North China. Furthermore, top-ranking anomalies (sea ice shift in the Barents and Kara Sea, and sea surface temperatures in the east Pacific and northwest Atlantic) were found to induce the aforementioned tremendous climate anomalies in the dust source area. Analyses, based on large-ensemble Coupled Model Intercomparison Project Phase 6, yield results identical to the reanalysis data. Thus, the climate variabilities at different latitudes and synoptic disturbances jointly facilitated the strongest spring sandstorm over the last decade.  相似文献   

继续教育不应冷落书法教育     

万应均 《继续教育研究》2006,(3):122-123

书法是我国传统文化,在我国继续教育领域中几乎冷落了书法教育。致使我国国民书写水平较差,书法素养极低,很难适应我国物质文明和精神文明的高度发展。继续教育要开展好书法教育,应从四个方面做好工作:转变观念,端正对书法教育的思想认识;建立相关考核评价制度;加强师资培训;建立健全书法研讨团体,培养一批书法测试员。  相似文献
