高校辅导员是大学生思政教育的主体力量，是大学生日常服务与管理的直接承担者与实施者，对于大学生的成长与成才扮演着重要角色，发挥重要的作用。由于社会现状以及自身认知等原因，高校辅导员职业认同感不一，职责定位不明确，特别是高职高专院校的特殊性与层级性，辅导员的职业认同感亟待培养与关注，寻求相关路径进行解决具有理论研究价值以及现实参鉴意义。College counselors are the main force of ideological and political education of college students, who is the directly responsible for the university students on daily service and management. They play an important role for the growth and development of college students. Because of the social status and cognitive reasons, college counselors occupation identity is not a duty, the positioning problem is not clear, especially the particularity of Higher Vocational Colleges and hierarchy, identity of instructor occupation to cultivate and seek attention have theoretical research value and realistic reference meaning.
In the paper, two nonlinear estimation methods based on chaotic theory, surrogate data method and Lyapunov exponents, are used to distinguish the difference of PP wave intervals (time series of the pulse main peaks). After brief introduction of the corresponding algorithms, two typical different healthy state signals of PP wave intervals are compared by using the two methods. The obtained results demonstrate that the signals are distinguished effectively in quantitative way. With surrogate data method, which is applied to identifying the existing chaos of PP intervals of pulse, it is proved that the series of PP intervals of pulse are chaotic. Largest Lyapunov exponents of PP wave intervals are calculated. The Largest Lyapunov exponents of the two kinds of signals are both positive and different from each other. The chaotic character of arrhythmia is much more significant than that of healthy state.
雾(灰)霾的形成是自然活动、科技、人类活动的结果。今年两会中科院院长白春礼在回答相关雾霾问题时指出，雾霾的三大“源”凶：燃烧、汽车尾气、扬尘，但是pm2.5的第二次爆发原因很复杂，包括一些化学反应。其实，雾霾形成的原因是：1) 雾霾颗粒的积累，即燃烧、汽车尾气、扬尘作用的结果；2) 雾霾颗粒向上的动力——热空气向上运动，无线传播，即向上运动的电磁波网；3) 无持续风向。三个条件都具备才会爆发持续的雾霾天气，缺一不可，pm2.5的二次爆发正是上述三个条件共同作用的结果。
The fog and haze formation is the result of natural activity, science and technology, and human activity. This year President Bai Chunli of NPC and CPPCC CAS indicates the reasons of the fog and haze in answering related problem, which are combustion, vehicle exhaust, and dust. But the reasons of the second outbreak of pm2.5 are complex, including some chemical reaction. In fact, the reasons of the fog and haze are: 1) the accumulation of the fog and haze, namely the results of combustion, automobile exhaust, and dust effects; 2) the fog and haze particles’ upward momentum—hot-air upward movement and wireless communication, namely the electromagnetic wave net sports; 3) no sustained wind. These three conditions indispensable lead to persistent fog and haze weather, and the second outbreak of pm2.5 results from the above three conditions together.
After joining the WTO for more than ten years, China has made great achievements in economics and foreign trade. Since manufactured products, especially mechanical and electrical products as well as high-tech products, are accounting for more and more proportions of export products, China’s export structure has been upgrading. However, China’s exports are still in the phase labeled “made in China”, which means that the added value of export products is low. This paper calculates the added value of trade in 12 industrial departments in China between 2001 and 2011 by using the trade-added value method. As a result, we come to a conclusion that after joining WTO, technology-intensive industries in China have been increasing their trade-added value steadily, while those traditional labor-intensive industries are losing their positions on the ladder of the international division of labor.
