从任务驱动到价值认同:集团化办学的师资流动与融合

北京市东城区史家教育集团基于不同学校的办学实际,在指向真实育人情境的教师专业提升中促进教师流动,促进了教师队伍的均衡优质发展。在推进教师流动工作中,需直面价值认同与绩效工资制度的差异两大挑战;经历任务驱动、项目带动、领袖群动三个阶段;增进龙头校与伙伴校在办学价值、育人实践、专业质点、治理方式等层面的融合;通过内容丰富、形式多样的专业培训,激发教师流动的内在动力。

城市流动人口犯罪成因及预防对策

改革开放后,原有的城乡格局被打破,城乡一体化的步伐加快,社会经济迅速发展,大量人口进入城市,这些城市流动人口创造经济价值与社会价值的同时也带来了一系列问题,尤其是大量城市流动人口引发的刑事案件与治安案件频发,给城市发展带来了新的挑战。分析城市流动人口犯罪的成因,加强对城市流动人口的管理,建立依法管理城市流动人口的有效机制,从而达到预防犯罪的目的,为人民生活创造一个健康有序的环境。

Design Methodology Research of the Floating Foundation for the Offshore MW-Rating Wind Turbine

With the rapid growth of the offshore wind industry, the innovative floating offshore wind turbine is chosen as the most feasible device to harvest the vast wind energy in deep water area. However there is no practical design guide for the floating wind turbine especially the floating foundation. In this paper, based on the investigation on the worldwide floating wind turbine and current available expertise on floating platforms accumulated in offshore O/G （oil and gas） industry, an integrated design methodology is presented according to the specialized characteristics of wind turbine, including the type selection of foundation and mooring system, design standard, design procedure, design conditions, key technologies involved. Finally a semi-submersible floating foundation is designed to support certain megawatt-rating wind turbine of Goldwind and also performance analysis and code checks are performed to validate the design. The design method of the floating foundation provided in this paper is proved feasible and can be adopted in practical engineering design.
