新形势下危机领导的路径依赖模型

领导干部应对危机事件的能力日显重要,是加强党执政能力建设的重要方面,已成为新时期评价领导干部能力的重要内容。探究危机领导,构建有中国特质的危机领导方式成为新的研究期待。在研究过程中,从哲学方法论上追寻领导危机的路径依赖,利用其价值和事实两个层面论证契合领导危机的诉求。厘析传统型危机领导的路径依赖模型,在对传统型加以借鉴的同时,运用＂三论合一＂、＂源流共治＂的理论及方法,构建新形势下对危机有效领导的路径依赖模型。     

企业危机管理过程中的信息活动分析

企业危机管理有5个阶段:危机信息检测,危机准备,危机抑制,危机恢复和危机学习。企业危机管理过程实质上是一个信息收集、分析、传递、利用的信息管理过程。     

创建运动恢复理论新体系

为完善竞技运动理论体系,提高运动恢复的质量和效益,针对过去训练理论偏重生物性恢复,忽略心理和社会性恢复的现实,构建了由生物学、心理学和社会学三方位组合的运动恢复理论新体系。     

突发性公共危机信息传播模式的时段性特征及管理对策

在界定突发性公共危机的定义和分类以及综述各种信息传播理论模式的基础上，结合突发性公共危机信息传播的特点，并参照Defleur的“互动过程模式”和Fiona Duggan及Linda Banwell的危机信息传播模式，提出基于信息流强弱的突发性公共危机信息传播模式。在此基础上分析信息传播过程的时段性特征，并针对所提出的模型和5个阶段的特征对政府如何有效应对突发性公共危机的管理对策进行探讨。     

A mathematical model for power output in rowing on an ergometer

A mathematical model relating power output of rower to stroke rate on an ergometer (the Concept II Indoor Rower TM, Model C) is studied. The model is used to analyse the ergometer performance of a particular rower. It is determined that he can be more efficient (i.e. decrease power output while maintaining fixed velocity) by decreasing stroke rate, but at the expense of increasing force during the drive. It is also shown that he can be more efficient by increasing the drag factor (using higher vent setting) without increasing force. Dependence of power output on rowing style (the shape of the force curve) is also examined. It is shown that variation of force during the drive has little effect on efficiency, but efficiency is reduced by asymmetry of the force curve that favours the legs.

Effects of active and passive recovery on performance during repeated-sprint swimming

Abstract

The effect of active and passive recovery on repeated-sprint swimming bouts was studied in eight elite swimmers. Participants performed three trials of two sets of front crawl swims with 5 min rest between sets. Set A consisted of four 30-s bouts of high-intensity tethered swimming separated by 30 s passive rest, whereas Set B consisted of four 50-yard maximal-sprint swimming repetitions at intervals of 2 min. Recovery was active only between sets (AP trial), between sets and repetitions of Set B (AA trial) or passive throughout (PP trial). Performance during and metabolic responses after Set A were similar between trials. Blood lactate concentration after Set B was higher and blood pH was lower in the PP (18.29 ± 1.31 mmol · l^?1 and 7.12 ± 0.11 respectively) and AP (17.56 ± 1.22 mmol · l^?1 and 7.14 ± 0.11 respectively) trials compared with the AA (14.13 ± 1.56 mmol · l^?1 and 7.23 ± 0.10 respectively) trial (P < 0.01). Performance time during Set B was not different between trials (P > 0.05), but the decline in performance during Set B of the AP trial was less marked than in the AA or PP trials (main effect of sprints, P < 0.05). Results suggest that active recovery (60% of the 100-m pace) could be beneficial between training sets, and may compromise swimming performance between repetitions when recovery durations are short (< 2 min).     

视界与视点：现代西方理性危机的文化批判

现代西方理性危机的文化批判,是整个20世纪以来西方社会全面危机的思想文化呈现。其批判的视界是：悲剧意识体验、文化形态史论、＂新马克思主义＂路径和后现代主义思潮;而其批判的视点却是：意识形态批判、技术理性批判、大众文化批判、性格结构与心理机制批判、社会功能批判、政治权力批判等。面对＂现代化＂和传统文化＂整体性转型＂双重境遇,中国＂文化现代化＂在超越现代西方理性危机的智识性努力中,自当具有深刻的启示。     

现代企业危机的本质

对危机及危机管理的研究已经历了二十多年,但企业危机非但没有减少,并越来越高发,越来越严重,究其原因是未能对危机的本质进行深入的研究。本文从现代企业与企业生态关系的层面上对企业危机本质进行研究,认为现代企业危机的本质在于企业制度体系的根本缺陷。
