The effects of basketball on students＇ social adaptation ability and mental health

After several years of intense study, the most urgent problem those college students must face is employment, what＇ s more, with the sustaining development of China＇ s economy and the accelerating pace of social progress, the society shows much more need for the comprehensiveness and adaptation ability of talents. However, under the influence of long-term examination-oriented education, college students are only content with the courses required now which leads to the lack of large scope of expertise and ability to solve practical problems, being narrow-minded, and having poor flexibility, creativity and manipulative ability. With the addition of the significant differences between the campus and the society, many college graduates always have the feeling of maladjuslanent when entering the society, for example, they are usually lack of effective learning methods, strong social responsibilities and self-learning abilities and have poor understanding and mastery of professional knowledge, poor unity consciousness, poor manipulative ability in social practices and poor cognitive competence, furthermore ,they tend to have great intercommunicative obstacles and can not evaluate themselves and others correctly.

Model test of the influence of cyclic water level fluctuations on a landslide

Many landslides in reservoir areas continuously deform under cyclic water level fluctuations due to reservoir operations. In this paper,a landslide model, developed for a typical colluvial landslide in the Three Gorges Reservoir area, is used to study the effect of cyclic water level fluctuations on the landslide. Five cyclic water level fluctuations were implemented in the test, and the fluctuation rate in the last two fluctuations doubled over the first three fluctuations. The pore water pressure and lateral landslide profiles were obtained during the test. A measurement of the landslide soil loss was proposed to quantitatively evaluate the influence of water level fluctuations. The test results show that the first water level rising is most negative to the landslide among the five cycles. The fourth drawdown with a higher drawdown rate caused further large landslide deformation. An increase of the water level drawdown rate is much more unfavorable to the landslide than an increase of the water level rising rate. In addition, the landslide was found to have an adaptive ability to resist subsequent water level fluctuations after undergoing large deformation during a water level fluctuation. The landslide deformation and observations in the field were found to support the test results well.
