文职人员提高政治理论课教学能力的思考

政治理论课是党在军队开展的政治工作的重要组成部分,是军队思想政治教育的主渠道、主阵地。作为没有部队经历的文职人员,提高政治理论课教学能力,要从坚定理论信仰、提升知识水平、拓宽沟通渠道等方面下功夫。     

建构主义理论对高校普通心理学教学模式改革的启示

教师教学不能只给学生灌输知识,而应该引导学生用自己的头脑来建构知识。建构主义理论正是基于此,提出了合作学习、支架式教学等方式,并取得良好成效,从而成为了"教育心理学的一场变革"。本文在阐述建构主义理论的学习观和教学观的基础上,重点探讨这场革命中提出的新观点和新理念对于高校普通心理学教学模式以及教学方法的启示,以期能够在普通心理学的实际教学中找到新突破,提高学生的学习效果和教师的教学效果。     

基于模糊逻辑和证据理论的故障诊断方法

针对故障诊断过程中信息损失的问题和D-S证据理论在处理模糊信息时的局限性,在模糊逻辑的基础上,将决策级信息融合技术应用于故障诊断系统中,提出了一种基于模糊逻辑和D-S证据理论相结合的多传感器信息融合综合故障诊断方法。该方法以模糊隶属函数来实现基本可信度分配,充分利用各种传感器的冗余和互补信息,可显著提高故障诊断的准确率,实例验证了该方法的合理性和有效性。     

Operational aspects of a future war between Egypt and Israel

The peace treaty between Israel and Egypt has survived since 1979. Even so, following the events in Egypt, there is a growing tension between the two states, particularly surrounding the Sinai, which could cause a crisis and even a war. In such a case, the main battlefield would be in Sinai, and there would be several dominant aspects. Some of them would appear for the first time, compared with previous wars, such as a collision between Israeli and Egyptian units of around corps size. Other aspects would be more familiar, such as the ratio between the size of the forces to that of the battlefield, the “fog of war,” night fighting, “friendly fire” and deception.     

基于有限理性理论的虚拟士兵感知行为建模研究

针对当前虚拟士兵感知行为模型的缺陷,介绍有限理性理论和基于有限理性虚拟士兵的概念,分析了加入有限理性理论的虚拟士兵的特点,提出了基于有限理性虚拟士兵的感知行为模型。该模型包括有限视觉模型、有限听觉模型和有限记忆模型,基于该感知模型的虚拟士兵在感知、决策和运动能力方面与类似真实士兵具有较高的一致性。这对虚拟士兵的感知行为建模研究具有一定的探索意义。     

【专题】复杂陆战场环境下的智能感知理论现状与发展

近年来,由于基于深度学习方法的智能检测算法不断演进,其网络结构不断进化,实用化程度不断提高,因此,将其应用于复杂战场环境下,形成实用化智能感知能力的可行性不断提高。然而算法的可靠性、可解释性问题目前仍未完全解决。本文认为,在未来的地面无人平台系统框架内,使用基于深度学习的目标检测识别方法,融合多种传感器感知信号,探索如何可靠地收集无人平台附近敌我车辆、人员、相关物体状况以及视距内的地理与气象环境信息,能够实现多元智能感知过程,构建智能复杂体系,为无人平台实现复杂战场环境感知理解,自主环境判定、自主行走、自主危险判定甚至威胁自动处置提供技术储备。同时,这也将是军队下一步智能感知理论方向的主要任务。     

基于知识图谱和二级传播理论的网络舆情事件传播分析

在目前的网络舆情事件传播分析中,尽管生命周期模型能够较好地描述舆情事件的发展规律,但却忽略了部分时期之间存在的共性特征,无法充分体现意见领袖对网络舆情事件传播过程的影响。本文提出了一种基于知识图谱和二级传播理论的网络舆情事件传播分析方法,首先,构建网络舆情事件知识图谱;然后,基于知识图谱计算用户影响力挖掘意见领袖;最后,考虑到意见领袖的重要地位,为有效刻画网络舆情传播规律、周期与途径,根据传播学二级传播理论构建网络舆情事件传播模型,将生命周期模型的五个时期按照舆情发展态势划分为三个阶段：潜伏期（爆发期阶段）、爆发期（成熟期阶段）以及成熟期和衰退期（消亡期阶段）。实验结果表明,该方法能够有效计算和发掘包括意见领袖在内的用户影响力,传播、分析网络舆情事件效果较好。     

Blast resistance evaluation of urban utility tunnel reinforced with BFRP bars

To improve corrosion-resistance of shallow-buried concrete urban utility tunnels(UUTs),basalt fiber reinforced polymer(BFRP)bars are applied to reinforce UUTs.As the UUT must have excellent survival capability under accidental explosions,a shallow-buried BFRP bars reinforced UUT(BBRU)was designed and constructed.Repetitive blast experiments were carried out on this BBRU.Dynamic responses,damage evolutions and failure styles of the BBRU under repetitive explosions were revealed.The tunnel roof is the most vulnerable component and longitudinal cracks develop along the tunnel.When the scaled distance is larger than 1.10 m/kg1/3,no cracks are observed in the experiments.When the BBRU is severely damaged,there are five cracks forming and developing along the roof.The roof is simplified as a clamped-supported one-way slab,proved by the observation that the maximum strain of the transverse bar is much larger than that of the longitudinal bar.Dynamic responses of the roof slab are predicted by dynamic Euler beam theory,which can consistently predict the roof displacement under large-scaled-distance explosion.Compared with the UUT reinforced with steel bars,the BBRU has advantages in blast resistance with smaller deflections and more evenly-distributed cracks when the scaled distance is smaller than 1.260 m/kg1/3 and the steel bars enter plastic state.Longer elastic defamation of the BFRP bars endows the UUT more excellent blast resistance under small-scaled-distance explosions.     

Civil–military relations and organisational preferences regarding the use of the military in Chinese foreign policy: insights from the debate on MOOTW

ABSTRACT

This article analyses the positions of the Chinese civilian leaders and military elites on Military Operations Other Than War in order to shed light on their preferences about the use of the armed forces in foreign policy between the late 1990s and the early 2010s. Over time, a significant divergence developed between civilians and soldiers until 2011, when the Libyan crisis happened. The study also prompts important considerations about our understanding of civil–military relations in China and future role of the People’s Liberation Army as a tool of statecraft in foreign policy.     

Why they fight? Reconsidering the role of motivation in combat environments

The current combat motivation model based on primary group thesis assumes that the main force behind motivation is peer-bonding or otherwise known as unit cohesion. Cohesion is perceived as an all-encompassing factor that leads to satisfactory (or unsatisfactory in lack thereof) military effectiveness and performance in conflict environments. However, the article identifies three main problems with this perspective: 1. mono-dimensional view of motivation; 2. motivation based on heteronomy, and 3. self-reporting bias. The current model does not consider motivation as a separate entity from cohesion; it does not place motivation as fundamental human value; lastly, it takes motivation as granted by-product of socialization. The article proposes a new combat motivation model based on The Self-Determination Theory. The theory maintains that human motivation requires satisfaction of three psychological needs of competence, relatedness, and autonomy. The degree of satisfaction of those three needs leads to different types of regulated motivations – a continuum from intrinsic to extrinsic – each of which has specifiable consequences for learning, performance, and well-being of an individual.
