A NEW STANDARD FOR PREEMPTIVE MILITARY ACTION AGAINST WMD THREATS

International law clearly requires an imminent threat of attack as a justification for the preemptive use of military force. However, the standard definition of an imminent threat was derived centuries before the development of nuclear, chemical, or biological weapons or ballistic missiles and other delivery systems that can reach their targets in a matter of minutes. Any use of force to alleviate threats posed by weapons of mass destruction (WMD) prior to tactical warning of the actual launch of such weapons falls into the legally and ethically controversial category of “anticipatory self-defense,” leaving decision makers potentially liable to prosecution for war crimes. Effective and ethical enforcement of nonproliferation therefore demands a standard for imminence of threat broad enough to allow military action as a last resort but sufficiently restrictive to prohibit indiscriminate action against suspected WMD programs. Following a critical review of selected literature and cases on preemption, the author proposes a new standard for preemptive military action: the existence of operational WMD, or a clandestine program to develop WMD, in contravention of international law. The author discusses the implications of this new proposed standard, which at the time of writing would permit preemptive attack against WMD-armed terrorist groups but prohibit it against all states except Iran and possibly North Korea.     

BEYOND DECLARATIONS OF INTENT

This essay explores the obligations arising from the United Nations Convention against Transnational Organised Crime, signed in Palermo, Italy at the end of 2000. It also discusses the initiatives required to prepare the legal system and related infrastructure of Zimbabwe for its implementation. Zimbabwe joined more than 120 other countries in signing the Palermo convention, but has not yet ratified it. The ratification would enshrine the latest initiatives to develop effective strategies against transnational organised crime. The Palermo convention makes demands on the laws and institutions of states parties which could enhance their capacity to confront organised crime. Ratification signifies competence to implement the prescribed obligations, which can only occur after introducing suitable domestic laws, and adopting the necessary administrative mechanisms. The required reforms are bound to have certain policy and legislative implications for Zimbabwe. Regional initiatives complementary to the Palermo convention are expected to catalyse positive changes in Zimbabwe's response mechanisms.     

CORRUPTION,PERCEPTION AND FOREIGN DIRECT INVESTMENT

Bribery undermines human development and a transition to stable democratic rule. It props up illegitimate regimes as corporations bid for contracts by bribing, in a seeming race to the bottom. The world's wealthy are slowly waking up to this and criminalising this scandalous practice of bribing foreign public officials. However, such measures, if enforced, need to be combined with domestic anti-corruption strategies in the South. If this opportunity is missed, the risk of investing private capital in marginalised economies perceived to be highly corrupt is further upped, making investment-driven economic growth possibly even less unattainable.     

INTERNATIONAL REGIME OF FRESH FUEL SUPPLY AND SPENT FUEL DISPOSAL

Recent events in Iran and elsewhere demand a reevaluation of the need for increasing nuclear fuel supplies and assuring reliable flow of fuel to nuclear power user states vis-à-vis the need for strengthened security for all countries against the use of weapons of mass destruction (WMD). The right of countries to a guaranteed supply of nuclear energy for peaceful uses must be balanced with the global community's desire to limit flows of nuclear material and sensitive nuclear facilities that could create opportunities for nuclear proliferation. This article proposes elements of an international regime of fresh fuel supply and spent fuel disposal that will guarantee fresh fuel supplies to countries honoring their obligations under the Treaty for the Non-Proliferation of Nuclear Weapons (NPT), while reducing concerns about diversion of spent fuel for weapons purposes. A specific application to countries with small pre-commercial uranium enrichment plants is also proposed.

无人作战飞机近距对抗占位策略与方法

针对无人机作战中前置追踪占位法存在导弹发射条件苛刻且目标机动时成功率锐减和离散对策占位法应用局限性较大等问题,提出一种无人作战飞机近距对抗占位策略与导引方法。该占位策略为解算无人机近距对抗占位的伪跟踪点,并设计一种三维变结构导引律,引导无人机完成近距作战占位机动。仿真结果表明,该占位策略与导引方法快速有效,满足无人机近距对抗时的战术指标要求。

LDO稳压器敏感度建模与仿真技术

基于LDO稳压器在电磁干扰（EMI）下产生直流偏移失效的机理分析,展开敏感度建模与仿真方法研究。使用一款实验芯片,创新地引入片上电压传感器,用于测试EMI在LDO稳压器内部的传播特性。在敏感度建模中,建立等效电路模型,通过直流功能测试,Z参数阻抗特性测试验证模型的正确性,将该模型用于LDO稳压器的敏感度预测。在敏感度仿真过程中,通过分析关键子电路和不断增加寄生元件,仿真不同寄生因素对敏感度影响的权重。将仿真结果与传导直接注入法（DPI）片上测试结果对比,仿真结果与DPI测试在频域1MHz至1GHz匹配。
