毛泽东偏离正确处理人民内部矛盾理论原因新探

关于毛泽东偏离正确处理人民内部矛盾理论的原因 ,过去论者多从社会历史方面去寻找。笔者认为 ,造成这种状况的主要原因 ,不但在理论之外 ,更在理论本身。由于缺乏主要矛盾的支撑 ,由于对社会主要矛盾的判断脱离实际 ,由于在处理人民内部矛盾的方法上沿袭老经验 ,由于对经济领域的矛盾缺乏必要的重视 ,最终导致毛泽东在实践中偏离了自己提出的这一在科学社会主义发展史上具有里程碑意义的理论。     

Fire truck relocation during major incidents

The effectiveness of a fire department is largely determined by its ability to respond to incidents in a timely manner. To do so, fire departments typically have fire stations spread evenly across the region, and dispatch the closest truck(s) whenever a new incident occurs. However, large gaps in coverage may arise in the case of a major incident that requires many nearby fire trucks over a long period of time, substantially increasing response times for emergencies that occur subsequently. We propose a heuristic for relocating idle trucks during a major incident in order to retain good coverage. This is done by solving a mathematical program that takes into account the location of the available fire trucks and the historic spatial distribution of incidents. This heuristic allows the user to balance the coverage and the number of truck movements. Using extensive simulation experiments we test the heuristic for the operations of the Fire Department of Amsterdam‐Amstelland, and compare it against three other benchmark strategies in a simulation fitted using 10 years of historical data. We demonstrate substantial improvement over the current relocation policy, and show that not relocating during major incidents may lead to a significant decrease in performance.     

The American way of war in Africa: the case of Niger

ABSTRACT

Increasing attention paid to US casualties in far-flung places such as Tongo Tongo, Niger, and headlines claiming ‘secret wars’ have fueled discussion about American military’s involvement in Africa. Though the continent has been a part of the American way of war since the beginnings of the US – consider the early combat actions of US Marines in Tripoli –, current African conflicts are challenging our understanding of war and approaches to winning it. This article examines the ways America seeks to achieve its ends in Africa with a particular focus upon the last 10 years of US counter-terrorism and stability operations in Niger and the Sahel Region. The author proposes unifying American, Allied, and partner efforts through a strategy of Active Containment.
