试论德里达解构方法论(策略)的矛盾性

德里达的解构论的方法论的矛盾性表现为:他既反对西方传统理性主义的客观主义,强调哲学与非哲学的区别,但同时,他的解构论也存在着客观主义的倾向,主要表现是文本"延异"过程中的无主体性。因此,他的这种倾向遭到了哈贝马斯等人的批判。     

区域经济一体化进程中小城镇扮演的角色与发展举措分析

小城镇能够承接大中城市的职能,一般都要发展成为功能性城市,其发展质量在一定程度上决定着城乡一体化程度.在合适的区位上,“小城镇团”会围绕发挥核心作用的小城镇得到发展,其作用主要在于:分摊大城市职能,拉动农村城镇化,促进新型城乡关系建设.根据以往经验,小城镇发展成功的举措包括提升小城镇的行政级别、在合理区位上布局中心地、改善小城镇的交通条件、整合小城镇资源构建产业基地.     

心智游移的适应性功能及其理论解释

心智游移是指注意从当前任务或者外界环境转移到内部想法和感觉的现象。尽管以往的研究主要关注心智游移的代价,但是最近的研究发现心智游移也具有一些积极的适应性功能。相关功能主要包括外部监控、自传体计划、提高创造力、促进决策和降低负性情绪等。相应的理论解释有情境管理假说、内容管理假说、意识连续体假说等。未来的研究应该进一步为相关功能提供直接的证据,也可以从内容管理、时间管理和情境管理的角度探索提高心智游移适应性功能的技术。     

直隶总督王文韶与甲午战后督直举措述论

甲午战争之后,王文韶临危受命担任直隶总督兼北洋大臣。在不到四年的时间里,着力整顿战后直隶政局,本着保全“洋务”人才的原则,建立稳定官僚团队;疏陈统筹北洋防务,积极谋划整顿陆军、添建炮台和筹建北洋海军;力主官督商办修筑卢汉铁路,并筹办铁路学堂;积极筹办近代学堂、发展教育以及支持直隶维新活动。王文韶在甲午战后督直期间的一系列举措,对战后直隶的稳定与发展产生积极影响。

Cheating among elementary school children: A machine learning approach

Academic cheating is common, but little is known about its early emergence. It was examined among Chinese second to sixth graders (N = 2094; 53% boys, collected between 2018 and 2019) using a machine learning approach. Overall, 25.74% reported having cheated, which was predicted by the best machine learning algorithm (Random Forest) at a mean accuracy of 81.43%. Cheating was most strongly predicted by children's beliefs about the acceptability of cheating and the observed prevalence and frequency of peer cheating at school. These findings provide important insights about the early development of academic cheating, and how to promote academic integrity and limit cheating before it becomes entrenched. The present research demonstrates that machine learning can be effectively used to analyze developmental data.     

Learning statistics with interactive pictures using R Shiny: Generally preferred,but not generally advantageous

Constructing interactive web apps has become more accessible for instructors, for example, by using the R package Shiny. Here we explored learners' preferences and the efficiency of interactive simulations versus static pictures in acquiring statistics knowledge of Cohen's d and standard normal distribution. Results revealed that students' spontaneous interaction with pictures was infrequent (pilot study, N = 26). While prompts (Exp. 1, N = 152) effectively ensured the manipulation of simulations, student exposure to interactive simulations led to longer learning times though similar test performance compared with student exposure to static pictures. Multiple interactive representations led to lower test performance than single interactive and static representations (Exp. 2, N = 117). Though no advantage was gained regarding learning outcomes, participants preferred the interactive variant (Exp. 3, N = 119). Taken together, this study demonstrates that the superiority of interactive pictures cannot be assumed to hold in general. Further work should evaluate how mental model construction can be effectively scaffolded by interactive simulations.

Multi-objective output feedback control for autonomous spacecraft rendezvous

In this paper, the problem of robust output feedback control for a class of spacecraft rendezvous systems is investigated, which contains parameter uncertainty, external disturbance, poles assignment, _H∞-norm$H_{\infty }\mathrm{-}\mathrm{norm}$, variance and input constraints. The aim of this problem is to design a dynamic output feedback controller such that the closed-loop poles are placed within a specified disc, the _H∞$H_{\infty }$ norm of the transfer function from disturbance to output is ensured to be less than a prespecified disturbance attenuation level, the steady-state variance for each state of spacecraft rendezvous system is guaranteed to be less than the prespecified individual upper bound, and the actual control input is confined into a certain range simultaneously. Based on the Lyapunov theory, the existence conditions of such controller are derived in terms of linear matrix inequalities (LMIs). An illustrative example is given to demonstrate the effectiveness of the proposed control design method.
