工具理性和技术主义掩盖教育评价的目的性或伦理性追求,导致教育评价的目的对生活的质的增长和对人自我实现的意义视而不见,教育评价的方法、测量手段、理念和价值具有强烈的数字表征倾向,拘囿于对个人竞争力的增值,缺乏对精神世界的关怀。亚里士多德将“实践”理解以自身为目的从而实现幸福的活动,与教育评价的本体追求具有极高的契合度。在实践哲学视域下,教育评价不单单是出于满足主体需要的行为,而是基于实践理性以发展的、创造的、开放的方式对某一教育行为使主体产生变化的好与坏进行价值判断的行动,它具有目的在内、以人为中心和贯穿教育过程始终这三种实践的应然属性。教育评价的实践品质带来的必然是生动的、鲜明的、具有终极关怀的和生命感召的教育实践。以亚里士多德的实践哲学谨慎审视教育评价的目的性或伦理性追求,重拾教育评价的实践品质,使教育评价复归其本体价值。

为全面评估我国对“一带一路”沿线国家的石油投资风险情况,选取2010—2021年期间36个“一带一路”沿线国家的数据,从政治、经济、市场、资源潜力和双边合作5个方面构建风险评估指标体系,基于因子分析法和熵值法评估我国对沿线国家的石油投资综合风险水平。研究表明:“一带一路”沿线国家的石油资源丰富,但存在资源地域分布不均、发展中国家石油资源开发能力有限、产消比例不均衡等问题;在36个“一带一路”沿线国家中,我国对叙利亚进行石油投资的政治风险最高,捷克的政治风险最低。建议在“一带一路”倡议下推进石油投资保护协议的制定,健全对外石油投资风险监测平台,完善财务管理和经济风险预防制度等措施来防范石油投资的相关风险。

Based on dynastic period division and AMS ^14 C dating performed on the sedimentary layers at Zhongba and Yuxi sites,and also the analysis of Na,Ca and Mg of 201 sedimentary samples from Zhongba site and that of Ca and Na in 47 sedimentary samples from Yuxi by using an inductively coupled plasma-mass spectrometry（ICP）,we found that there were 35 time periods when the contents of Ca and Na were reversely correlated,*** the content of Ca was the highest,the content of Na was the lowest,and vice versa. Among them,there were 21 time periods when the content of Ca was the highest,and Na was the lowest,indicating that there were about 21 prosperous periods of ancient salt production at Zhongba site since *** 14 time periods with the peak values of Na while the low values of Ca indicate 14 declined periods of salt production at Zhongba site since *** conclusion obtained from the reverse relationship between Ca and Na contents in this paper is consistent with that＂the salt production at Zhongba site started in the new stone age,developed in the Xia and Shang dynasties,reached at the heyday in periods from the Western Zhou to the Han Dynasties,maintained stable to develop in the Tang and the Song dynasties,and gradually declined after the Song Dynasty because the sea salt were conveyed into Sichuan region,however,still had production in the 1970s-1980s＂,educed from archeological *** the above mentioned results indicate that there is a reverse relationship obviously between the contents of Na and Ca in sediments at Zhongba site for ancient salt production,which can be used to reveal the process of rise and decline of ancient salt industry at Zhongba site.

Controller Design of Flexible Double-Inverted Pendulum with Uncertainties Based on T-S Fuzzy Inference System

Controller Design of Flexible Double-Inverted Pendulum with ...

2015年中国智能自动化学术会议

作者： Jimin Yu Liangsheng Nan linyan huang College of Automation Chongqing University of Posts and Telecommunications

Mathematical modeling of the flexible double-inverted pendulum with uncertain friction coefficient is presented by Lagrange function in this paper. Based on Takagi-Sugeno fuzzy inference and parallel distributed compensation(PDC)theory, the controller design approach is proposed. Based on the concept of effective maximum overlap-rules group, the stability condition of T-S fuzzy system for flexible double-inverted pendulum is relaxed to finding a local public positive definite matrix. As a result, stability conservativeness of T-S fuzzy system is decreased. According to the new relaxed stability condition, linear matrix inequalities are designed for solving the feedback gain of each subsystem, and the controller based on parallel distributed compensation is given. Simulation results show that the designed controller can effectively control the uncertain flexible double-inverted pendulum.
