共产党员先进性之我见

对党员先进性的要求,不能简单地把对政党整体的要求与对党员个体的要求划等号,不能简单地用先进英模来衡量大多数普通党员,不能简单地把理论上的要求与实际操作的行为准则划等号,也不能简单地把特殊时期的要求与平时要求混同起来。在市场经济条件下党员有自己正当的利益,党员的先进性在于把个人利益与社会利益有机地统一起来。应从人性的角度定位党员可操作的行为准则,使党员先进性要求切实可行。     

背景音乐对人类学习效率影响的脑与行为研究进展

重力势能锁止型外骨骼设计及其效能评价

现存的被动式外骨骼存在助力效果不明显等缺陷。基于人体步态特征,提出了将人体行走过程中的重力势能转化为人体抬腿过程中动能的原理,通过弹簧、曲柄滑块机构、棘轮棘爪机构以及链传动机构的组合,设计了一款被动式下肢机械外骨骼,并通过外骨骼动力学分析和生理消耗指数实验测试的方法进行了外骨骼性能评价。动力学分析结果表明,穿戴外骨骼后髋关节峰力矩总量降低了23.43%,髋关节做功总量降低了30.59%,初步验证了外骨骼的有效性。生理消耗指数实验测试结果表明, 穿戴外骨骼对于短距离动作转换未产生显著效果,但在长距离行走和上坡行走中分别降低了8.1%和10.4%的能量消耗。因此,该下肢外骨骼助力性能得到了验证,为相关领域的研究提供了实例化参考。     

The case for demilitarising Lesotho

ABSTRACT

The Kingdom of Lesotho spends around five per cent of its annual budget – some 700 million Maloti ($US52.6 million) in 2017 – on the Lesotho Defence Force (LDF). Lesotho’s geographical position means that the LDF has no meaningful role regarding its primary function of defending the country from external aggression and it hardly engages in its secondary functions. In addition, the LDF has a long history of interference with democratic processes and engaging in human rights abuse. The financial resources currently allocated to the LDF could do far more for security, widely defined, if they were allocated to a number of other government expenditure categories.     

Human security in pastoralist areas of Eastern Africa

Abstract

Pastoralist groups in Eastern Africa are extremely vulnerable as a result of inter-community conflicts, the harsh terrain, and unfavourable climatic conditions. They have been neglected by successive regimes on matters of socio-economic development. At present pastoralist areas in Eastern Africa have the lowest literacy rates and insufficient health care facilities. This article interrogates the historical relationship between governments, humanitarian groups and pastoralists. It notes with great concern that pastoralists have been branded as hunger-stricken populations with insignificant economic potential that can be harnessed from their day-to-day livelihood. They are treated as sedentary populations who need a constant supply of relief food to keep going. In order to reverse these misconceptions, the article places emphasis on mitigating the threats of intra-community conflicts, diseases and natural disasters through investment in social schemes and infrastructure in order to open up the areas for service provision. Indeed, for a majority of the pastoralists, insecurity comes not so much from traditional security concerns, but from human insecurity concerns about their survival, preservation of their lifestyle and well-being in a day-to-day context.     

AFRICA

Political violence, at times perceived as terrorism, remains a major security challenge in Swaziland. The common view is that this violence is perpetrated by those who feel marginalised from the political process. Central to the hypothesis advanced in this paper is that any effective solution to the menace of political violence and the security challenges it poses begins with an awareness of the symbiotic relation between security, human rights and democracy. It has been empirically proven that abuse of human rights can lead to violence, which negates peace and security in any society. In terms of content the paper looks at the shape of political violence in Swaziland. Next, it discusses the strategies and ideas behind efforts by the Swazi state to combat political violence and the counter-arguments. The final section shows the inextricable link between security, human rights and democracy; and argues that recognising this linkage can provide the key to unlocking the security puzzle in Swaziland.     

基于CREAM的后方仓库叉车装卸运输弹药HRA评估

基于不完全信息演化博弈模型的网络舆情传播羊群行为

以网络舆情传播过程中大部分人对事实不了解为前提,在这部分群体内构建基于不完全信息环境的两人对称演化博弈模型。提出了两人对称博弈矩阵来决定个体策略的选择,建立了复制动态方程说明不同策略群体比例的演化方向,演化时引入个体的记忆长度,根据设定的交互规则更新各自的观点值及记忆列表。仿真分析模型表明,在此环境中很容易产生羊群行为,群体内的个体都选择盲从并且观点保持一致。此外,羊群行为的集聚产生受多种因素影响,主要与采取分析策略的交互利益、成本系数以及记忆长度有关。本文对科学分析引导网络舆情的传播有一定实际意义。     

基于行为建模的移动代理性能评估

针对移动代理的分布式应用性能评估需求,建立了移动代理生命周期中主要行为的网络负载模型和时间消耗模型.在3种典型分布式应用想定下,分析了基于C＼S模式和移动代理模式的应用实现基本过程,对两种模式下的网络负载和执行时间进行了仿真比较,结果证明了在访问节点数量较多,网络传输速率较低时,移动代理模式的具有更好性能.
