Police Corruption: Towards a Working Definition

According to the International Committee of the Red Cross (ICRC) publication Interpretive Guidance on the Notion of Direct Participation in Hostilities under International Humanitarian Law, all civilians (including child soldiers) lose their immunity from direct targeting ‘for so long as’ their actions amount to direct participation in hostilities. All civilians can, however, access the revolving door of protection and return to their civilian activities – complete with full immunity from direct targeting – provided the nature of their direct participation was spontaneous and disorganised. Once it can be ascertained that their participation in hostilities amounts to continuous combative functions, they relinquish their access to the revolving door of protection, and can be targeted at all times until they abandon their formal or functional membership of the belligerent group. This piece analyses how the revolving door phenomenon and the notion of continuous combative functions apply in instances where civilian child soldiers are directly participating in hostilities.

US warfare in Somalia and the trade-off between casualty-aversion and civilian protection

This article examines the ways in which the two normative concerns of casualty-aversion and civilian protection influenced US military strategy in the particular context of the asymmetric conflict in Somalia in the early 1990s. The article critically evaluates US military operations through the prism of international humanitarian law and examines whether American forces started prioritizing casualty-aversion over the safeguarding of Somali civilians. Finally, by drawing on emerging moral guidelines (such as Michael Walzer's idea of ‘due care’), the article examines whether lower numbers of Somali civilian deaths could have been achieved if marginal increases to the risks faced by US soldiers had been accepted.

研究现代城市地震火灾危害及对策 ,对于消防安全非常重要。以 1 995年日本神户地震及发生的地震火灾为例 ,分析了现代城市地震火灾的特征 ,提出了如何应对城市地震火灾及消防减灾对策     

城市消防规划若干问题探讨

近几年,我国火灾形势严峻,城市发生重特大火灾事故次数和火灾直接经济损失都呈上升趋势,其主要原因在于城市消防规划落后于城市建设的发展。因此,加快城市消防规划和城市公共消防设施的发展,建立城市消防安全体系,对于提高城市预防火灾的能力至关重要。

Reaction degree of composition B explosive with multi-layered compound structure protection subjected to detonation loading

The explosive reaction degree and protection from explosions are concerns in the military field.In this work,the reaction degree of the composition B explosive was investigated experimentally.Multi-layered compound structures were used as barriers to weaken the blast loads.A comprehensive experiment using a high-speed camera and image processing techniques,side witness plates,and bottom witness plates was presented.Using the experimental fragment velocities,fragment piercing patterns,and damage characteristics,the reaction degree of the explosive impeded by different multi-layered com-pound structures could be precisely differentiated.Reaction parameters of the explosive obstructed by compound structures were obtained by theoretical analysis and numerical simulations.Unlike the common method in which the explosive reaction degree is only distinguished based on the initial pressure amplitude transmitted into the explosive,a following shock wave reflected from the side steel casing was also considered.Different detonation growth paths in the explosive formed.Therefore,all these shock wave propagation characteristics must be considered to analyze the explosive response impeded by compound structures.     

PIP工艺制备的C/SiC复合材料的氧化行为

PIP工艺制备的C/SiC复合材料中SiC基体富碳,因此增强体和基体均容易氧化。碳纤维和无涂层保护C/SiC复合材料试样在400~1300℃的氧化速率随温度升高而加快,低温为反应控制,高温为扩散控制。CVD-SiC涂层保护C/SiC复合材料和由CVD-SiC层、自愈合层、CVD-SiC层三层涂层保护C/SiC复合材料在400~1300℃的氧化先随温度升高而加快,然后减慢。三层涂层在800~1300℃有非常好的保护效果。扫描电镜照片显示自愈合层的玻璃态物质进入涂层裂纹中,填充裂纹且阻挡氧的通过,从而有良好的抗氧化保护效果。     

消防行政即时强制研究

消防行政即时强制是消防行政强制的一种,由于其适用的目的和程序与消防行政强制执行不同而具有特殊性。对消防行政即时强制的法律性质、实施条件、手段、救济等问题进行了初步探讨。
