The Chinese and Asian impact on Russian nuclear policy

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe.

机载光电传感器视轴指向的智能辅助决策方法

机载光电传感器视轴应尽可能接近目标线,以缩小指向偏差而不使目标偏离传感器瞬时视场,飞行员在复杂的战场态势下进行视轴操控具有一定困难。针对该问题,提出了一种机载光电传感器视轴指向的智能辅助决策方法,该方法以传感器视轴指向的数学模型为基础,通过专家知识建立引导规则,完成目标与各传感器的配对;计算配对后的各传感器视轴指向偏差和偏差变化率,采用模糊控制算法得出视轴偏移率,引导各传感器视轴指向与之配对的目标。仿真结果表明了该方法能够合理引导各传感器视轴指向目标,并能将视轴指向偏差缩小在很小的范围。

军民融合背景下军工企业多元化发展战略研究

冷战结束后,欧美多数军工企业在军转民的过程中采取多元化的经营战略,壮大企业规模并寻求进一步的发展。随着我国军民融合战略的深入实施,军工企业不再是封闭独立的单一军品生产基地,而是顺时应势逐步实现军品和民品同步多元化发展的战略转型。通过分析我国军工企业军转民的历史进程与国际经验,结合多元化战略的特点,考察军工企业在军转民过程中实施多元化战略的动因,构建军工企业多元化战略的选择函数。本文认为,军工企业选择多元化战略应考虑企业自身实际情况,积极响应国家政策,培育核心竞争力;同时,军转民过程作为军民融合深度发展的重要一环,会促使军工企业往多元化的方向发展,而多元化战略的实施也会加快军民融合深度发展的进程。

Stolen trauma: why some veterans elaborate their psychological experience of military service

The embellishment of a warrior biography has a long history but examples of veteran elaboration of traumatic experience have become increasingly apparent. Although legislative change in the UK has removed the penalties for fabrication and a progressive decline in the military footprint may have increased the likelihood of such false trauma narratives, a paradigm shift in explanations for mental illness underpins this phenomenon. The recognition of post-traumatic stress disorder (PTSD) in 1980, followed by studies to identify risk factors, led to a greater appreciation of psychological vulnerability. As a result, the use of shame to discourage acts formerly labelled as “cowardly” or “lacking in morale fibre” is no longer considered appropriate. Recent conflicts in Iraq and Afghanistan generated popular sympathy for service personnel, whilst media focus on PTSD has led the UK public to believe that most veterans have been traumatised by their tours of duty.
