农村“空校”现象原因与对策分析

一、农村“空校”现象产生的原因 一般说来，农村“空校”不外乎学额少，校舍多。出现这种现象的原因是多方面的，除了客观上人口出生率下降和合理“裁撤并”学校导致部分校舍闲置外，有相当一部分闲置校舍是由于不当的人为因素造成的。     

教师职业生涯“高原现象”原因与对策分析

教师主要表现为教师教学热情耗尽、教学情感淡漠、职业角色模糊等。其产生根源有工作内容,组织因素和个人因素等三个方面。教师在"职业高原"阶段如果不能有效突破,不仅有碍于其自身的成长与发展,更不利于教育教学改革的顺利进行以及学生的健康成长。解决教师职业生涯"高原现象"要从个人和学校两个方面入手。     

“星期一现象”的原因与对策

星期一是一周新的开始,经过双休日的充分休息,学生在星期一应该精力充沛,思想集中。但事实并非如此。每到星期一,一部分学生懒懒散散,学习情绪不佳,课堂上反应相对以往显得较为迟钝,学习积极性、主动性相对滞后,师生之间的交流时常出现“暂时短路”现象,其主要表现如下：     

高校青年教师“入党难”原因与对策分析

近年来,高等院校普遍存在着青年教师党员比例偏低,申请入党积极分子偏少,甚至出现部分高学历、高职称的青年高级知识分子不愿入党的现象,究其原因是多方面的,诸如思想政治工作的滞后、行政管理中重业务轻政治教育、基层党组织工作不到位以及社会环境中的非正常现象等都是影响青年教师入党的消极因素。但是,这种影响仅仅是一个外因或外力,高学历高职称青年教师不愿入党的真正取决因素是他们价值取向中消极因素的增长趋势这一内力的作用。高校党组织应明确地意识到:注重积极引导青年教师入党的内在动力,才是高校党组织积极引导青年教师入党工作的重中之重。做好这项工作不能仅靠单纯的价值灌输教育,而要依靠青年人的自我教育。即应重视青年教师的自我调节、自我管理、自我教育能力的培养,以价值分析取代价值灌输。

义务教育阶段体罚现象调查与原因分析

一、问题的提出 我国现代教育早在解放区时就要求废除体罚.建国后,教育部于1952年2月14日发出明确批示:废止对学生施行体罚或变相体罚.以后,在不同时期曾多次明令严禁体罚学生.自1985年以来,更是以立法形式在《义务教育法》、《教师法》、《未成年人保护法》等法律中做了明确规定.

Numerical simulation of pollutant diffusion and decay process after a water pollution incident in the Three Gorges Reservoir

We established a hydrodynamic model to simulate the pollutant transport and decay process in the case of a pollution incident in the sections of the Yangtze and the Jialing passing through the city area of Chongqing. The Boussinesq assumptions and the Navier-Stokes equations of incompressible fluid were applied to setting up the pollutant diffusion equations and the equations for the decay process. E. coli was taken as the example pollutant, and chloride dosage, light, temperature and ultraviolet intensity were considered in the equations for bacterial decay process. The calculated values of the fluid velocities in the two rivers agree well with corresponding measured results, indicating an ideal accuracy of the model. In simulation, the concentration of E. coli in water was assumed to be zero before the accident. The upriver boundary velocity was ?1.35 m/s for the Jialing flow and 1.75 m/s for the Yangtze flow, and the downriver boundary was water depth set at 0. Simulation results show that the bacteria are transported downstream along the riverbank. A long and narrow pollutant belt develops at 12 h after the start of the accident ascribed to the quick longitudinal transfer. After the pollution sources are cut off, the pollutant concentration decreases slowly, mostly by advection and diffusion, suggesting inadequate self-purification ability of the rivers and the necessity of effective decontaminating measures in the case of a pollution incident. The model can be a useful tool for understanding the polluting situations of an improper discharge incident and evaluating the effects of decontaminating measures for the water body of the Three Gorges Reservoir.

Legal study on water environmental protection of Three Gorges Reservoir Area

Water environment security of the Three Gorges Reservoir Area has become a more extensive concern since the impoundment of the reservoir. This paper describes the existing water environmental hazards and defects in current legal system for water environmental protection in this area, and also discusses their possible causes and potential problems in the future based on first hand materials and other literature. According to the theories of integrated river basin management and environmental equity principle, legal proposals are put forward, which include building an unitary legal system dedicated to the Reservoir Area, setting up a basin authority of the Yangtze River to preside over the resources protection and development, using interests' compensation system to solve interest conflicts among different reaches, and making concrete regulations to direct public participation in water environmental security protection of the Three Gorges Reservoir Area.
