The Problem of Weak Nuclear States

Governments are increasingly recognizing the problem posed by internally weak nuclear-capable states. The problem, however, is under-theorized. This article brings together literature on sovereignty and international order, the nonproliferation regime, and weak states, and introduces new concepts to provide a more structured understanding of this problem. Insight comes from focusing attention on the function and governance of two nuclear estates (termed the production and operational estates), and on their resilience to decay and disorder occurring within the state and society. Drawing on empirical observation, the authors suggest a typology of weakness in nuclear states, involving state fragmentation typified by the former Soviet Union, the “hard weak state” typified by North Korea, and the internally conflicted state typified by Pakistan. Although these types give rise to distinctive difficulties, their alleviation depends heavily on the maintenance of internal authority within the state and estates, the presence or absence of cooperative relations, and the international regulatory framework's vitality.

无人机避障航路规划方法研究综述

随着无人机作业空域从中高空不断向低空甚至超低空拓展,复杂的低空障碍环境对无人机造成了严重的威胁。研究无人机避障航路规划理论与方法,对于保障无人机的飞行安全和提升其任务效率具有重要作用。对无人机避障航路规划方法的研究现状进行了梳理,首先,根据航路规划问题所建立的优化模型,将规划方法划分为基于数学规划的方法、基于路标图的方法、基于空间分解的方法、基于势场的方法、基于随机规划的方法和基于机器学习的方法六个大类。然后,分别介绍了各类型方法的基本原理、代表性研究以及优缺点。最后,对避障航路规划方法未来可能的研究方向进行了展望。综述表明,复杂环境下无人机三维航路规划方法的研究仍有提升空间;未来应考虑将传统规划方法与新一代人工智能技术相结合;航路规划方法研究应充分考虑机载传感器的实际性能和工作特性;规划航路的可跟踪性问题也亟待解决。

领悟社会支持与高中生学习投入的关系:自尊和未来教育规划的链式中介作用

目的:探究领悟社会支持对学习投入的影响,以及自尊和未来教育规划的链式中介效应。方法:采用领悟社会支持量表、自尊量表、未来教育规划问卷和学习投入量表,对446名高中生进行施测。结果:①各变量两两之间均存在显著地正相关(r=0.32~0.50,p<0.001);②领悟社会支持能正向预测高中生学习投入;③在领悟社会支持对高中生学习投入的预测中存在三条路径:一是自尊的中介作用;二是未来教育规划的中介作用;三是自尊和未来教育规划的链式中介作用,效果值分别为:14.81%,27.78%和16.67%。结论:领悟社会支持不仅直接影响高中生学习投入,还通过自尊和未来教育规划影响高中生学习投入。     

CIVILIAN PARTICIPATION IN THE EDUCATION AND DEVELOPMENT OF MILITARY OFFICERS

Much is made in the security sector reform literature of the role of civil society as an overseer and monitor of the security sector, contributing to improved accountability and governance. This paper looks at how the notion of ‘civil society capacity’ needs to be disaggregated in order to develop meaningful strategies to assist civil society organisations to impact security sector reforms in complex, post-conflict contexts like the Democratic Republic of Congo. It draws on fieldwork conducted with 200 Congolese civil society groups that are attempting to engage in current security sector reform processes, and looks at which capacities are required to improve oversight by civil society groups.     

Belligerent beginnings: John F. Kennedy on the opening day of the Cuban missile crisis

This article – based on data that employs interviews conducted with British Army personnel – adopts a social theory of learning in order to examine how both formal and informal learning systems have affected organizational learning within the Army in relation to the counter-insurgency campaign in Afghanistan. It argues that while the Army has adopted new, or reformed existing, formal learning systems, these have not generated a reconceptualization of how to conduct counter-insurgency warfare. It, furthermore, argues that while informal learning systems have enabled units to improve their pre-deployment preparations, these have created adaptation traps that have acted as barriers to higher-level learning.
