全日制专业学位硕士管理中的问题及原因分析

管理者管理理念的滞后、管理者管理手段的落后、教学条件不能满足现代教学管理要求、管理对象自身素质存在不足等是全日制专业学位硕士管理工作中面临的问题或困难。本文结合全日制专业学位硕士的培养目标就这些问题的成因作了深入的分析。     

Multi-lagged-input iterative dynamic linearization based data-driven adaptive iterative learning control

This article presents a multi-lagged-input based data-driven adaptive iterative learning control (M-DDAILC) method for nonlinear multiple-input-multiple-output (MIMO) systems by virtue of multi-lagged-input iterative dynamic linearization (IDL). The original nonlinear and non-affine MIMO system is equivalently transformed into a linear input-output incremental counterpart without loss of dynamics. The proposed learning law utilizes the desired trajectory to cancel the influence from iteration-by-iteration variations, as well as additional multi-lagged inputs to improve control performance. The developed iterative estimation law is more effective and also makes estimation of the unknown parameters easier because the dynamics for each parameter to represent are decreased by dividing the system into multiple components in the multi-lagged-input IDL formulation. Moreover, the proposed M-DDAILC does not need an explicit and accurate model. It is proved to be iteratively convergent with rigorous analysis. Both a numerical example and a practical application to a permanent magnet linear motor are provided to verify the validity and applicability of the proposed method.     

外部知识源化、知识积累与中国工业绿色增长——动态异质门槛效应研究

针对开放式创新驱动与绿色发展融合下工业绿色增长路径及动力来源多元化特征，基于中国工业2009-2015省际面板数据，通过考虑非期望产出的Super-SBM模型测算环境和能源约束下的工业绿色增长结构，并采用改进的动态门槛回归模型，从地区知识积累视角系统探究外部知识源化路径驱动工业绿色增长机制的知识积累动态门槛效应及其时空异质性。研究表明：中国工业绿色增长整体水平较低，地区异质性显著；总体上，外部知识源化对工业绿色增长起到了正向作用，但其存在显著的知识积累异质门槛特征：知识积累一旦突破了临界规模，外部知识源化路径驱动工业绿色增长的正向效应则呈现减弱，且知识积累门槛时空分布存在较大差异。     

加强三峡库区移民思想政治教育的对策研究

三峡库区移民搬迁任务已经顺利完成,移民思想政治教育在取得明显成绩的同时,也暴露出了针对性不强、实践滞后以及方法不科学等问题。这与有关的领导干部重视不够、＂一手软一手硬＂问题没有得到根本解决、移民思想政治教育队伍建设缺乏力度、移民思想政治教育理论研究滞后以及对移民思想政治教育的特殊性认识不足等原因紧密相关。因此,在后期移民思想政治教育过程中,要以高度重视为前提,加强疏导为手段,解决实际问题为关键,加强管理、严格执法为保障,切实加强和改进移民思想政治教育。     

坏消息英语商务信函中的“面子”问题

坏消息英语商务信函传达的是不利于读信人的信息,因此威胁到了读信人的“面子”。写信人在写作这类信函时应该在篇章安排、句子表达和词汇选择三个层面上积极运用各种礼貌策略来保全读信人的“面子”。     

应当纠正数学概念的"一名多义"现象

文章例举了代数学中三个“一名多义”的概念,剖析了由于这三个概念的“一名多义”现象导致的相关理论的混乱,呼吁应当纠正数学概念的“一名多义”现象。     

把“红色虚拟旅游”引入到高校纲要课教学中

课堂教学是高校思想政治教育的主渠道。充分利用现代新媒体,通过跟随课本红色虚拟旅游,开展“重上井冈山”、“重走长征路”、“回延安”、“沂蒙颂”等红色旅游系列活动,增强大学生的课堂参与度,从而提高教学实效,传播精神正能量,实现引导大学生认可接受并主动践行社会主义核心价值观的目的。以《重走长征路》为例,对红色虚拟旅游教学改革的基本原则、实施方案、心得体会进行总结。

中文文本知识元的构建及其现实意义

中文文本知识元的构建是解决汉语自动分词问题,实现对中文自然语言理解,并对知识内容进行操作、管理之基础。应当以汉语主题词为基础,构建中文文本知识元,建立知识元数据库,完成对知识内容的自由操作和管理。图1。参考文献26。     

The effects of ACL injury on quadriceps and hamstring torque,work and power

The aim of this study was to assess isokinetic torque, work and power between non-injured, ACL (anterior cruciate ligament)-deficient and ACL-reconstructed individuals. Ten healthy, non-injured individuals, seven unilateral ACL-deficient individuals and six unilateral ACL-reconstructed individuals were assessed for isokinetic quadriceps and hamstring strength at 1.05 and 3.14 rad.s-1. Peak torque, total work, average power and the ratio of peak torque to body mass were computed for both velocities. Peak torque was also corrected for body mass, using allometric modelling. The non-injured individuals showed significantly greater quadriceps peak torque to body mass ratios than the ACL-deficient and ACL-reconstructed individuals at both velocities, and greater hamstring peak torque to body mass ratios than the ACL-deficient group at 3.14 rad.s-1 (P < 0.05). The ACL-deficient individuals displayed greater quadriceps and hamstring peak torque, total work and average power than the non-injured individuals at 1.05 rad.s-1 (P < 0.05). The ACL-deficient individuals also displayed significantly greater peak torque, total work and average power than the ACL-reconstructed individuals for the quadriceps at both velocities (P < 0.05). The ACL-deficient individuals demonstrated greater hamstring peak torque and total work than the non-injured individuals at both velocities (P < 0.05). The allometrically modelled peak torques at both isokinetic velocities demonstrated that the quadriceps muscle values were significantly higher in the non-involved than the involved limb. The hamstring peak torques corrected for body mass were significantly higher in the non-involved than the involved limb only at 1.05 rad.s-1. The main finding from the present study is that isokinetic measures in ratio-scaled or absolute units yield a different outcome and, hence, interpretation compared with the allometric approach.
