Cross‐Milieu Terrorist Collaboration: Using Game Theory to Assess the Risk of a Novel Threat

This article uses a game‐theoretic approach to analyze the risk of cross‐milieu terrorist collaboration—the possibility that, despite marked ideological differences, extremist groups from very different milieus might align to a degree where operational collaboration against Western societies becomes possible. Based upon theoretical insights drawn from a variety of literatures, a bargaining model is constructed that reflects the various benefits and costs for terrorists’ collaboration across ideological milieus. Analyzed in both sequential and simultaneous decision‐making contexts and through numerical simulations, the model confirms several theoretical arguments. The most important of these is that although likely to be quite rare, successful collaboration across terrorist milieus is indeed feasible in certain circumstances. The model also highlights several structural elements that might play a larger role than previously recognized in the collaboration decision, including that the prospect of nonmaterial gains (amplification of terror and reputational boost) plays at least as important a role in the decision to collaborate as potential increased capabilities does. Numerical simulation further suggests that prospects for successful collaboration over most scenarios (including operational) increase when a large, effective Islamist terrorist organization initiates collaboration with a smaller right‐wing group, as compared with the other scenarios considered. Although the small number of historical cases precludes robust statistical validation, the simulation results are supported by existing empirical evidence of collaboration between Islamists and right‐ or left‐wing extremists. The game‐theoretic approach, therefore, provides guidance regarding the circumstances under which such an unholy alliance of violent actors is likely to succeed.     

Dynamic Forecasting Conditional Probability of Bombing Attacks Based on Time‐Series and Intervention Analysis

In recent years, various types of terrorist attacks occurred, causing worldwide catastrophes. According to the Global Terrorism Database (GTD), among all attack tactics, bombing attacks happened most frequently, followed by armed assaults. In this article, a model for analyzing and forecasting the conditional probability of bombing attacks (CPBAs) based on time‐series methods is developed. In addition, intervention analysis is used to analyze the sudden increase in the time‐series process. The results show that the CPBA increased dramatically at the end of 2011. During that time, the CPBA increased by 16.0% in a two‐month period to reach the peak value, but still stays 9.0% greater than the predicted level after the temporary effect gradually decays. By contrast, no significant fluctuation can be found in the conditional probability process of armed assault. It can be inferred that some social unrest, such as America's troop withdrawal from Afghanistan and Iraq, could have led to the increase of the CPBA in Afghanistan, Iraq, and Pakistan. The integrated time‐series and intervention model is used to forecast the monthly CPBA in 2014 and through 2064. The average relative error compared with the real data in 2014 is 3.5%. The model is also applied to the total number of attacks recorded by the GTD between 2004 and 2014.     

中国会计不道德行为影响因素的实证研究——基于组织和社会环境的视角

从组织和社会环境角度出发,采用实证研究,运用多元统计分析方法,建立了基于组织和社会环境视角的会计不道德行为模型.通过该模型发现,影响会计不道德行为的主要因素是上级的压力、法律的惩戒力度和领导层的道德状况,并且还发现各个因子对会计不道德行为的贡献程度是不一样的.     

基于数量柔性契约的双源应急物资采购定价模型

针对灾害事件发生的不确定性以及灾害发生后应急物资需求量的爆发式增长,本文设计了一个政府主导的基于数量柔性契约的双源应急物资采购模型。在存在一个现货市场的情况下,政府除了常规采购外,还会与供应方签订一份数量柔性契约,用以建立政企联合储备应急物资的合作关系。通过数理推导,本文发现灾害事件发生概率,政府自身储备量,现货市场采购价格会对双方决策产生重要影响,并给出三个影响因素在满足不同条件时政企双方的最优决策,同时进一步分析了这三个因素对政府采购成本与供应方利润的影响。最后,通过数值模拟的方式对所得结论进行了验证。本文的研究为政府与企业构建联合储备应急物资的合作关系提供了指导与依据。

考虑时效与公平性的震后应急物资动态配送优化研究

大规模地震后应急物资的高效保障是应急救援有效开展的必要前提。震后应急物资运输与配送包括从区域储备仓库和外围物资集散地运输到区域应急配送中心、由区域应急配送中心配送到各个受灾点两个阶段。应急物资保障具有持续时间长、需求紧迫性强和物资相对短缺等特点。本文以应急物资保障时效性与分配公平性为目标,建立了考虑多种运输方式、多时段动态的应急物资配送中心选址与运输配送路径优化的多目标规划模型,并基于此模型设计了一种带精英策略的非支配排序的遗传算法,以九寨沟地区地震灾难情景对模型进行实证研究,验证了模型和算法的有效性,以期为震后应急物资保障提供理论指导与决策支持。     

上级发展性反馈与创造力：一个被调节的中介模型

 在当前复杂和快速变革的环境中,创造力对组织获取竞争优势至关重要。作为与创造力相关联的重要因素,研究者们对于领导行为对创造力的作用保持了长期的关注。反馈不仅是领导者日常行为的重要组成部分之一,也是组织中常用的激励和行为矫正工具。        以自我效能理论和关系认同理论为基础,从领导和组织成员互动视角,探讨上级发展性反馈对组织成员创造力的影响及其内在机制。采用问卷调查方法,通过3阶段分时序方式,收集来自某综合性重点大学所属科研团队的442位科研人员及其领导的配对数据,运用层次回归和Bootstrap方法进行数据分析和假设验证。        研究结果表明,①上级发展性反馈正向影响组织成员创造力;②创新自我效能部分中介上级发展性反馈与组织成员创造力之间的关系;③组织成员对领导的关系认同感调节上级发展性反馈与创新自我效能之间的关系,并进一步调节创新自我效能在上级发展性反馈与组织成员创造力之间的中介作用,即当组织成员对领导的关系认同感高时创新自我效能的中介作用显著,而当关系认同感低时创新自我效能的中介作用不显著。        研究结果在一定程度上扩展了对于领导反馈与创造力间关系的理解,丰富了上级发展性反馈影响创造力的内在机制的探索,发现了上级发展性反馈影响组织成员创造力的重要边界之一,也一定程度上丰富了关系认同理论的运用范围,领导者可以通过提供发展性反馈以及与组织成员建立良好的关系来促进其创造力。
