Military Innovation and Tactical Adaptation in the Israel–Hizballah Conflict: The Institutionalization of Lesson-Learning in the IDF

This article highlights a pattern of military adaptation and tactical problem-solving utilized by the Israel Defense Forces (IDF) while engaged in protracted conflict with the Lebanese militant group Hizballah. It discusses the IDF’s recent attempts to institutionalize their historically intuitive process of ad-hoc learning by developing a formal tactical-level mechanism for ‘knowledge management’. The diffusion of this battlefield lesson-learning system that originated at lower-levels of the organization is examined, as well as its implementation and effectiveness during the 2006 Lebanon War. A nuanced analysis of IDF adaptation illustrates the dynamic interplay between both ‘top-down’ and ‘bottom-up’ processes of military innovation.     

儒家孝文化:碑志文体的文化意蕴

在古代文献各类文体中,碑志文的写法最为固定,它的体例可以概括为世系、行治、卒葬和铭文四部分。这种历久不变的文体,透射出中国人超越生死的独特智慧——家族孝文化。世系的排列体现出孝的最基本的第一层含义——延续父母与祖先的生物性生命;行治的罗举体现出孝的更高一层含义——延续父母与祖先的高级生命;卒葬和铭文体现儒家孝道之宗族群居的伦理精神。     

DDS输出信号频谱结构的系统分析

首先介绍了直接数字合成(DDS)技术的基本原理和理想情况下DDS的输出信号频谱结构,然后分析了工程实际中DDS的误差信号来源,从信号与系统理论的角度解释了相位截断和幅度量化引起的DDS输出信号频谱的杂散,并在最后对D/A的非理想特性和参考时钟相位噪声的影响作了简要的说明。     

背景音乐对人类学习效率影响的脑与行为研究进展

背景青乐是与主体的意识或行为无直接关系,通过非青乐鉴赏环境这一媒介间接作用于主体意识与行为的音乐。近些年来将背景音乐引入教育领域来探讨其对学习效率的影响是研究的新课题。从背景音乐对学习效率影响的相关理论、背景音乐对学习效率影响的实验研究以及背景音乐影响的研究趋势等方面进行了综述。     

星空点源背景红外辐射场景生成模型

星空场景建模是空间目标识别与跟踪的关键技术之一.基于中段空间实验红外天文星表(MSX-IRAC),通过位置计算得到该星表内恒星在指定观测时刻、观测地点投影到视场所在平面的坐标,同时利用改进的光谱模板技术,生成视场内所有点源星体的红外光谱(1.2～35 μm),并对光谱积分得到指定谱段的辐射量,最后将恒星位置和辐射信息在二维图像上表现出来,从而实现了一个星空点源背景红外辐射场景生成模型,并通过实例仿真验证了该模型的正确性.     

美军“多域战”概念探析

"多域战"概念由美陆军率先提出,是美军在联合作战概念上的又一次创新。"多域战"是美陆军力图拓展多领域作战能力、美军反制"反介入/区域拒止"威胁和打造在未来高强度对抗战争中的新优势的有力手段。"多域战"概念具有作战领域多维扩展、要素体系高度融合、指挥体制扁平灵活、军队编制精简多能和技术装备革新整合的特点。近年来,美军不断推动"多域战"的完善,为其发展提供了理论支撑、科技支撑、实践支撑和智力支撑。美军"多域战"概念的实施前景挑战与机遇并存。     

PROTECTING CULTURAL MONUMENTS AGAINST TERRORISM

Famous cultural monuments are often regarded as unique icons, making them an attractive target for terrorists. Despite huge military and police outlays, terrorist attacks on important monuments can hardly be avoided. We argue that an effective strategy to discourage terrorist attacks on iconic monuments is for a government to show a firm commitment to swift reconstruction. Using a simple game‐theoretic model, we demonstrate how a credible claim to rebuild any destroyed cultural monument discourages terrorist attacks by altering the terrorists' expectations and by increasing the government's reputation costs if they fail to rebuild.     

The Use and Abuse of the ‘Dutch Approach’ to Counter-Insurgency

This article argues that there is little evidence supporting the existence of the often praised, and allegedly subtle and successful ‘Dutch approach’ to stabilisation and counter-insurgency operations in Iraq or Afghanistan. It denounces the uncritical use of the term and refutes suggestions of historical and cultural roots to such an approach, for instance in Dutch colonial warfare in the Indonesian archipelago. It concludes by explaining the true conditions that gave rise to this notion, which seems to feed into a gratifying national self-image of the Dutch as non-martial, conflict averse and tolerant, rather than offering an original and successful formula for countering insurgencies.
