战争设计工程中专家思维收敛过程的建模与分析

专家意见能否达成共识是战争设计工程中的一个关键问题.首先从复杂理论视角对专家思维过程的适应性、聚集性、非线性进行分析,接着将专家群体划分为两类并且运用马尔科夫转移矩阵对研讨过程建模,提出并证明了两类专家群体思维收敛的充分必要条件,得到群体思维收敛不仅与研讨过程中专家之间的关系影响矩阵有关,而且与专家的初始意见有关.最后通过计算机仿真进一步探索了群体思维收敛过程的影响因素.

载人飞船上升段轨道的Newton迭代设计法

本文对载人飞船上升段轨道的一种工程设计方法进行了探讨。该方法的特点是根据上升段飞行的特征,运用飞行力学原理选定其控制规律的数学模型,然后根据上升段轨道的中间约束条件和终端约束条件,利用Newton迭代法确定模型中的各待定参数。本文给出了该设计方法的流程图,并通过模拟计算论证了该设计方法的可行性。     

Moral Aspects of “Moral Injury”: Analyzing Conceptualizations on the Role of Morality in Military Trauma

In clinical circles, the concept of “moral injury” has rapidly gained traction. Yet, from a moral philosophical point of view the concept is less clear than is suggested. That is, in current conceptualizations of moral injury, trauma’s moral dimension seems to be understood in a rather mechanistic and individualized manner. This article makes a start in developing an adequately founded conceptualization of the role of morality in deployment-related distress. It does so by reviewing and synthesizing insights from different disciplines into morality and trauma. This discussion will lead to three positions: (1) values and norms are by definition characterized by conflict, (2) moral conflict may entail important social dimensions, and (3) moral conflict may lead to altered beliefs about previously held values. These insights provide important steps in further developing conceptions of the role of morality in deployment-related suffering.     

US-American Intervention in Europe: Morality,Justice, and Freedom in World War II Cinema

This article analyzes the American intervention in Nazi-oppressed Europe during World War II and the way in which this intervention is represented in film. Examining the visual and cinematic aesthetics of Saving Private Ryan and the mini-series Band of Brothers, the article seeks to demonstrate how film has responded to US intervention overseas. It is argued that the need to liberate Europe from the evil Other stands forth as the main, heavily moralized purpose of US military intrusion in the film and the mini-series being analyzed. To shore up this speculation, the author considers other films on the topic, namely, The Longest Day (1962) and Shutter Island (2009). The author claims that the scenes in the concentration camps that are crucial in Band of Brothers and Shutter Island have an ethical function, i.e. they justify US intervention in the foreign territory. Additionally, the article provides a brief overview of Playing for Time (1980), Schindler’s List (1993), The Devil’s Arithmetic (1999), The Grey Zone (2001), as well as the mini-series Holocaust (1978).
