军事法研究的价值取向与方法论

军事法研究的前提论证必须是重述军事学与法学二者如何作用才能推进军事法的繁荣 ,这一问题也应是军事法学科进路的研究宏线。军事法各子学科的理论视角都应围绕这一中轴展开。法学与军事学在军事法这一共同体中更多的体现了手段与目的的关系 ,而不是目的与目的的冲突与调和的关系 ,即军事法学是借用法学的理论来规范军事行为的一门社会科学。关于军事与法的内在冲突的理论阐述可以揭示军事法学研究应遵循的一般规则 ,为学科自治提供理论研究的方法平台。

挖掘高等数学人文价值,培养大学生探究能力

数学的人文要素对培养学生的探究能力具有重要意义,在数学教学中通过体现数学人文价值来培养学生的探究能力可采取以下几种尝试:介绍古今人们对有关数学方面的认识,帮助学生全方位了解数学;借助数学史料,再现数学知识的发现过程;开展专题研究,师生共同研讨数学知识中隐含的数学思想方法;利用“数学美”,再现数学的人文价值,为此教师需做好两种形态知识的转化工作,树立新型的数学教育信念。     

Two‐stage component test plans for testing the reliability of a series system

A system reliability is often evaluated by individual tests of components that constitute the system. These component test plans have advantages over complete system based tests in terms of time and cost. In this paper, we consider the series system with n components, where the lifetime of the i‐th component follows exponential distribution with parameter λ_i. Assuming test costs for the components are different, we develop an efficient algorithm to design a two‐stage component test plan that satisfies the usual probability requirements on the system reliability and in addition minimizes the maximum expected cost. For the case of prior information in the form of upper bounds on λ_i's, we use the genetic algorithm to solve the associated optimization problems which are otherwise difficult to solve using mathematical programming techniques. The two‐stage component test plans are cost effective compared to single‐stage plans developed by Rajgopal and Mazumdar. We demonstrate through several numerical examples that our approach has the potential to reduce the overall testing costs significantly. © 2002 John Wiley & Sons, Inc.

More on the search for an infiltrator

We have asymptotically solved a discrete search game on an array of n ordered cells with two players: infiltrator (hider) and searcher, when the probability of survival approaches 1. The infiltrator wishes to reach the last cell in finite time, and the searcher has to defend that cell. When the players occupy the same cell, the searcher captures the infiltrator with probability 1 ? z. The payoff to the hider is the probability that the hider reaches the last cell without getting captured. © 2002 John Wiley & Sons, Inc.

A bidirectional heuristic for maximizing the net present value of large‐scale projects subject to limited resources

We consider the scheduling of large‐scale projects to maximize the project net present value given temporal and resource constraints. The net present value objective emphasizes the financial aspects of project management. Temporal constraints between the start times of activities make it possible to handle practical problem assumptions. Scarce resources are an expression of rising cost. Since optimization techniques are not expedient to solve such problems and most heuristic methods known from literature cannot deal with general temporal constraints, we propose a new bidirectional priority‐rule based method. Scheduling activities with positive cash flows as early and activities with negative cash flows as late as possible results in a method which is completed by unscheduling techniques to cope with scarce resources. In a computational experiment, we compare the well‐known serial generation scheme where all activities are scheduled as early as possible with the proposed bidirectional approach. On the basis of a comprehensive data set known from literature containing instances with up to 1002 activities, the efficiency of the new approach is demonstrated. © 2003 Wiley Periodicals, Inc.

当代青少年价值取向研究

社会转型、价值观念的变革对我国青少年的价值取向产生了重大影响,也呈现了新的面貌,具体表现如下：人生价值观日渐趋向多元化;人生行为选择低于理性认识水平,言行脱节现象严重。要改变这样的状况,就需要社会、家庭、学校共同关注,给青少年正确的价值导向。     

论社会主义核心价值体系引领社会思潮的有效途径

社会主义核心价值体系引领社会思潮的有效途径包括：1．注意选准社会主义核心价值体系引领社会思潮的切入点：要加强对大众文化的引领工作,要优化社会心理环境,创新社会主义核心价值体系的表达方式。2．更加注重社会主义核心价值体系的优化与创新：要注重增强社会主义核心价值体系的吸引力和影响力。要拓展社会主义核心价值体系引领社会思潮的领域。3．要加强社会主义核心价值体系引领社会思潮的机制建设。
