Nowadays, Chemical-Biological-Radiological-Nuclear-explosive (CBRNe) risks are one of the world's main safety concerns. The radiological disasters of Fukushima and Chernobyl, the chemical events of Seveso or the release of Sarin in the Tokyo Subway, the biological emergencies such as the H1N1 flu or the recent Ebola outbreak, and recent news about the availability of non-conventional weapons acquired by fundamentalist organisations represent evidence of potential future threats. CBRNe risks are a real and global threat. The University of Rome, Tor Vergata, in collaboration with the most important Italian and international bodies working in the field of CBRNe safety and security, and supported by the North Atlantic Treaty Organisation and the Organisation for the Prohibition of Chemical Weapons, organises International Masters Courses on the Protection against CBRNe events. Within this framework, a Table-Top Exercise was planned, in collaboration with the Italian Ministry of Interior and Ministry of Defence. The scenario, the logistic organisation, on-going adjustments during the exercise and the outcomes are presented here and analysed.  相似文献

This study examines how young people who have joined the South African National Defence Force (SANDF) on the two-year Military Skills Development System (MSDS) contract experience military service, and the effect this has on their ability to readapt to civilian life. The first part of the study examines the theoretical debates associated with military socialisation and reintegration into civilian life. Hereafter, the findings are presented in terms of the experiences of MSDS privates serving in the infantry, those that have left, and the perceptions of employment agencies in terms of the marketability of military skills. The conclusion is reached that MSDS members experience their two years in the SANDF as life-changing, that this affects their ability to reintegrate back into civilian society, and that the skills acquired during military training is of limited market value. The conclusion is reached that more needs to be done to assist these young military veterans to adapt to civilian life and to augment their military experience with more marketable skills to enable them to find gainful employment.  相似文献

A districting problem is formulated as a network partitioning model where each link has one weight to denote travel time and another weight to denote workload. The objective of the problem is to minimize the maximum diameter of the districts while equalizing the workload among the districts. The case of tree networks is addressed and efficient algorithms are developed when the network is to be partitioned into two or three districts. © 2002 Wiley Periodicals, Inc.

ISIS (the Islamic State of Iraq and Syria) has become a key political and military actor in the Middle East and in North Africa. This essay aims at outlining ISIS warfare through an analysis of its operations in the frame of hybrid warfare theory proposed by Frank Hoffman. Therefore, the paper deals with: the role of terrorist tactics in ISIS warfare and the relationship between terrorism and insurgency; ISIS use of technology, mainly with regard to suicide attacks and to drones; and the relevance of urban warfare. Finally, the paper highlights how ISIS operates and the most threatening features of its warfare.  相似文献
