改革开放以来我国经济法取得的主要成效及发展方向

中国特色经济法是改革开放的产物,有力地促进了社会主义市场经济的健康、快速发展。经济法在保证经济实现科学发展的同时,自身也突破了对调整能力的传统认识,区分了经济法与行政法,明确了经济法的正确定位,创新了经济法的发展观,提出了“经济法主体”概念,冲破了公法与私法的界限,形成了与相关学科协调发展的经济法学研究格局。今后,经济法的发展必须重视从完善社会主义市场经济基本制度,健全现代市场体系,规范政府科学干预经济生活,宏观调控的重点、热点、难点问题和基础理论研究的创新上把握研究重点,保证经济实现科学发展。

一种新型的武器系统试验训练设备─—零飞试验仪

零飞试验仪（以下简称零飞仪）是一种用于火炮武器系统瞄准精度的检查、试验和训练仪器。当火炮武器系统进行真实目标试验时,设定弹丸飞行时间等于零（即零飞工作方式）．火炮炮管轴线应该直接指向目标。零飞仪就是与这种工作方式相配合的试验仪器,它有广泛的推广应用价值,可用于火炮、导弹武器系统的陆上联调、靶场试验、维修和训练。该设备具有８０年代国际先进水平,填补了国内空白。     

Efficient multinomial selection in simulation

Consider a simulation experiment consisting of v independent vector replications across k systems, where in any given replication one system is selected as the best performer (i.e., it wins). Each system has an unknown constant probability of winning in any replication and the numbers of wins for the individual systems follow a multinomial distribution. The classical multinomial selection procedure of Bechhofer, Elmaghraby, and Morse (Procedure BEM) prescribes a minimum number of replications, denoted as v*, so that the probability of correctly selecting the true best system (PCS) meets or exceeds a prespecified probability. Assuming that larger is better, Procedure BEM selects as best the system having the largest value of the performance measure in more replications than any other system. We use these same v* replications across k systems to form (v*)^k pseudoreplications that contain one observation from each system, and develop Procedure AVC (All Vector Comparisons) to achieve a higher PCS than with Procedure BEM. For specific small-sample cases and via a large-sample approximation we show that the PCS with Procedure AVC exceeds the PCS with Procedure BEM. We also show that with Procedure AVC we achieve a given PCS with a smaller v than the v* required with Procedure BEM. © 1998 John Wiley & Sons, Inc. Naval Research Logistics 45: 459–482, 1998     

Humanitarians at sea: Selective emulation across migrant rescue NGOs in the Mediterranean sea

Between 2014 and 2017, no less than 10 different non-governmental organizations (NGOs) conducted maritime Search and Rescue (SAR) operations off the coast of Libya. By rescuing over 100,000 migrants in three years, these NGOs became the largest provider of SAR in the Mediterranean. The theory of institutionalism suggests that organizations conducting similar activities are likely to converge in a process of mimetic isomorphism, deliberately imitating one another to increase their effectiveness and cope with uncertainty. These 10 SAR NGOs, however, developed two different rescue models: While some rescued migrants and disembarked them in Italian ports, others only simply assisted those in distress until the arrival of another ship transporting them to land. They also cooperated with Italian and European authorities to different degrees. Why did SAR NGOs imitated many elements of existing non-governmental rescue models, but discarded some others? This article argues that differences in material capabilities and organizational role conceptions are crucial to explain why newer SAR NGOs have imitated most but not all of their predecessors’ policies, engaging in a process of “selective emulation.”     

Path optimization for the resource‐constrained searcher

We formulate and solve a discrete‐time path‐optimization problem where a single searcher, operating in a discretized three‐dimensional airspace, looks for a moving target in a finite set of cells. The searcher is constrained by maximum limits on the consumption of one or more resources such as time, fuel, and risk along any path. We develop a specialized branch‐and‐bound algorithm for this problem that uses several network reduction procedures as well as a new bounding technique based on Lagrangian relaxation and network expansion. The resulting algorithm outperforms a state‐of‐the‐art algorithm for solving time‐constrained problems and also is the first algorithm to solve multi‐constrained problems. © 2010 Wiley Periodicals, Inc.
