武警部队重大改革必须向“能打胜仗”的战斗力聚焦

从关于国防和军队重大改革的重要论述入手,系统地阐述了武警部队重大改革必须向“能打胜仗”的战斗力聚焦。主要从三个层面进行分析：一是向提高部队整体素质及优化规模结构聚焦;二是向提高部队武器装备保障效能聚焦;三是向增强部队以执勤处突为中心的军事能力聚焦。     

大学英语四、六级考试最新改革特点及对策研究

2013年最新改革后的大学英语四、六级考试,在考试内容、分值比例和难度系数等方面都作了诸多调整,呈现出新的特点。结合此次改革特点和对某军校150名学员展开的问卷调查,提出三大对策：利用考试“反拔效应”,引发学员对于输出性技能的重视;充分重视翻译策略讲解,加强中国文化渗透;努力培养学员自主学习意识养成,提高学员自我听力训练量。     

基于多元评价的课程教学改革——以“中学化学微格教学”为例

基于"多元评价"的教育评价理论,在"中学化学微格教学"课程中先后进行了尝试性改革:增加"自我评价"、"组员评价"环节,适当调整"自评"、"组评"和"师评"的权重,编制并逐年完善了《微格教学评价表》,实现了评价主体多元化、定性评价与定量评价相结合、过程性评价与结果性评价相结合。

United Nations Security Council reform and the dilemmas of African continental integration

This article analyses the disunity among African states in terms of United Nations Security Council (UNSC) reform, and attributes it to the contest between South Africa and Nigeria. These two countries have been locked in a hegemonic contest for continental domination. To this end, the article notes that African unity, not in terms of protocol but on the basis of principles and cooperation, is sacrosanct in order for the African Union to make a significant contribution to the reform of the UNSC. It is asserted that the contest between South Africa and Nigeria has been symbolised by the continental leadership aspirations of the heads of state of both countries, and recommends that it be tamed through forging diplomatic and strategic partnerships between the ruling parties of these two countries. The influence of external actors on the African countries, particularly that of France, is underscored as a contributing factor in stalling the debate on the UNSC reform. It recommends that South Africa use its strategic partnership within the association of Brazil, Russia, India, China and South Africa (BRICS), particularly Russia and China as permanent members of the UNSC, to influence the realisation of the reform debate.     

The Success of the 2014 Nuclear Security Summit and its Contribution to the Nonproliferation Regime

The 2014 Nuclear Security Summit (NSS) in The Hague was a resounding success, both in organizational terms and in terms of substance. The new substance can be found in the Communiqué, as well as in innovative joint statements by participants, all of which may be considered as implementation of actions decided upon in the Final Document of the 2010 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons. The next two years in the NSS process cannot be business as usual. This viewpoint makes some suggestions for NSS states to undertake between now and the final summit in 2016, including preparations for winding down the NSS process as we know it.

Bounded flexibility in days‐on and days‐off scheduling

This article presents a flexible days‐on and days‐off scheduling problem and develops an exact branch and price (B&P) algorithm to find solutions. The main objective is to minimize the size of the total workforce required to cover time‐varying demand over a planning horizon that may extend up to 12 weeks. A new aspect of the problem is the general restriction that the number of consecutive days on and the number of consecutive days off must each fall within a predefined range. Moreover, the total assignment of working days in the planning horizon cannot exceed some maximum value. In the B&P framework, the master problem is stated as a set covering‐type problem whose columns are generated iteratively by solving one of three different subproblems. The first is an implicit model, the second is a resource constrained shortest path problem, and the third is a dynamic program. Computational experiments using both real‐word and randomly generated data show that workforce reductions up to 66% are possible with highly flexible days‐on and days‐off patterns. When evaluating the performance of the three subproblems, it was found that each yielded equivalent solutions but the dynamic program proved to be significantly more efficient. © 2013 Wiley Periodicals, Inc.

Traffickers,terrorists, and a ‘new security challenge’: Russian counternarcotics strategy and the Federal Service for the Control of the Drugs Trade

The collapse of the Soviet Union precipitated the massive expansion of drug use and trade in Russia. The country now has one of the largest populations of injecting drug users in the world and has become the largest single-country market for Afghan heroin. In 2003 the Federal Service for the Control of the Drugs Trade was created to coordinate a comprehensive counternarcotics strategy appropriate to the scale of this threat. The service continues to face a number of challenges in its early stages of development. However, it has made considerable advances in improving responses to large-scale organised crime and in building international cooperation.     

基于在线动平衡的磁轴承参数辨识

针对磁悬浮刚性转子系统,提出了一种基于在线动平衡的磁轴承参数辨识方法。采用已知大小和相位的不平衡质量作为激振源,根据动平衡仪测得的转子不平衡响应,求得磁轴承位移刚度和电流刚度。利用某型磁悬浮控制力矩陀螺对该方法进行了试验验证,得到了一定转速范围内的磁轴承位移刚度和电流刚度,证明了该方法的正确性和实用性。试验结果表明外转子型磁轴承位移刚度和电流刚度随转速的增加而下降明显。
