大学体育与健康课程课堂教学管理性策略研究

大学体育教学过程中,把课程教学与健康课程课堂教学进行紧密联系,能够更好地把握体育教学过程中存在的问题,以“健康”作为发展目标,更好地实现体育教学的发展目的。大学体育与健康课程课堂教学管理性策略的结合,注重从“健康”角度出发,采取有效的举措,更好地对原有体育教学机制进行创新,以崭新的观念看待体育教学工作,从而发挥课堂教学的作用。本文对大学体育与健康课程课堂教学管理性策略的研究,注重从教学规范、教学目标、教学内容、教学组织方法等方面考虑,对体育课堂教学存在的问题进行有效解决,从“策略”角度出发,更好地提升大学体育教学效果。

大学体育与健康课程课堂教学管理性策略应用分析

随着时代的发展,人们对于教育有了更深刻的理解,传统单一的教育模式逐渐被综合性的教育模式所取代。大学体育在传统的教学模式中只是单纯的进行体育技能的教学,但是新时期教育理念的指导下,很多大学在体育教学中结合健康课程进行课堂教学,进一步的深化了人们对于体育教学的理解,有助于培养学生的体育精神和健康意识。下面文章我们首先要认识到大学体育与健康课程课堂教学管理型策略应用的重要作用,然后了解目前大学体育与健康课程课堂教学管理性策略在应用中出现的一些问题,最后提出了合理的策略,提升大学课堂管理水平。

Novel dynamic anti-collusion ciphertext policy attribute-based encryption scheme in 5G D2D environment

To share data securely with secure attribute revocation,anti-collusion,and dynamic user management in the 5G device-to-device(D2D)environment,a novel dynamic anti-collusion ciphertext policy attribute-based encryption(NDA-CP-ABE)scheme in the 5G D2D environment is proposed.On the basis of the ciphertext policy attribute-based encryption algorithm,fine-grained access control and secure attribute revocation are realized,and the confidentiality of data is guaranteed.A polynomial function is adopted in the ciphertext generation phase to realize dynamic user management.A random number is used to prevent a collusion attack among the legitimate user equipment(UE),revoked UE,and external network attackers.Finally,on the basis of the Diffie-Hellman problem,the NDA-CP-ABE scheme is formally proved,and the simulation performances are compared with those of similar schemes.The results show that data can be securely shared through a D2D channel with secure attribute revocation,anti-collusion,and dynamic user management.Moreover,compared with similar schemes,the NDA-CP-ABE scheme has higher efficiency in encryption,decryption,and storage.

An Analysis on the Inconsistency of the Security Supervision Policy in the Method of Game Theory

This article expounds and proves the basic model of the inconsistency of the security supervision policy and makes an analysis in the method of game theory on the inconsistency of the security transaction-tax-rate policy, concludes that the security supervision department is inclined to increase or decrease the security transaction tax rate, thus points out ways for supervision department to surmount this difficulty.

Dynamic capabilities-based strategy innovation： a theoretical framework and empirical studies in Chinese firms

Based on investigations of 112 Chinese firms and studies on foreign leading corporations, a theoretical framework of dynamic capabilities based strategy innovation (SI) is put forward. Several large firms in China winning through SI were studied empirically. This paper complements previous publications on the theories of innovation and strategy. This work's findings will be useful for managers interested in our approach, which highlights the importance of SI and focuses on and points out the major pitfalls in the innovation processes. Implementing the dynamic capabilities based strategy innovation can effectively cultivate and develop core competences of corporations. It is concluded that implementing SI is the only path for Chinese enterprise growth in the intensified competition in the knowledge economy.

A Community Resilience Evaluation and Optimization Strategy based on Stormwater Management

In the context of disaster normalization,the concept of“resilience”has been gradually introduced into the field of disaster prevention and mitigation in urban communities.In order to resist the increasingly frequent disasters caused by extreme weather,it is necessary to shift the focus of building resilient urban communities to the level of stormwater management.Community resilience is a disaster prevention and mitigation capability based on community resources.In order to solve the deficiency of storm and flood management in the current construction of resilient communities in China,it is necessary to establish a quantitative evaluation system to evaluate it.This paper uses the analytic hierarchy process and Delphi method to establish a community resilience evaluation system from the perspectives of community material space level,community management level and individual level.Then three communities in Hefei City,Anhui Province are selected for practical application of the system,and corresponding optimization and transformation strategies are proposed.The results show that:(1)The resilience of community stormwater management is closely related to the integrated environment of the community,the allocation of flood control facilities and the daily disaster prevention and mitigation management;(2)The ability of disaster prevention and mitigation and the awareness of public participation of the residents in all communities are relatively weak,and the communities invest less in the popularization of stormwater management wisdom;and(3)Resilient communities should not only pay attention to the construction of non-engineering disaster prevention measures,but also to the application of small-scale green infrastructure oriented toward stormwater management.
