内外干扰因素对液体火箭发动机的影响分析

在已有的液体火箭发动机稳态工况的非线性数学模型基础上,计算分析了单干扰因素对液体火箭发动机参数的影响,用非线性方法和小偏差方法对比分析了两个干扰因素分别和共同对发动机参数的影响。所得结论可用于泵压式燃气发生器循环的液体火箭发动机试验结果分析、可靠性及故障分析,也揭示了此类发动机参数随各种干扰因素的变化规律     

军用数据库安全审计系统的设计

在指控系统应用过程中,需要审查与系统安全相关的所有操作,并对不安全的操作行为进行报警。根据指控系统中数据库审计四要素的要求,提出将应用系统级审计与数据库级审计相结合的方法,最终实现两种级别审计的统一。解决了以往指控系统审计方式单一的问题,满足了军用数据库安全防护的要求。

When are strategic narratives effective? The shaping of political discourse through the interaction between political myths and strategic narratives

Most research on strategic narratives has explored their creation, and their interaction with other elements of national power in the conduct of foreign policy. Yet, the issue of how the targeted political communities receive those strategic narratives, and thus how those narratives are likely to have a political impact, is understudied. This article argues that in order to understand the ways strategic narrative are received within a political community, political myths must be taken into account. It introduces a typology of political myths based on their degree of universality and their degree of coherence with other myths, and shows how those factors influence the reception of strategic narratives. These mechanisms are illustrated through a study of the reception of the Russian strategic narrative in France. This approach offers opportunities to assess the differentiated impact strategic narratives have on political communities.     

Clinical Characterization of Insomnia among Veterans with PTSD: Identifying Risk Factors for Diagnosis and Treatment with Sedative-Hypnotics

Abstract

Insomnia is prevalent among Veterans with post-traumatic stress disorder (PTSD), it exacerbates PTSD symptoms, and it contributes to impaired functioning and quality of life. To improve treatment outcomes, it is important to identify risk factors for insomnia and sedative-hypnotic use. Classification and regression trees and logistic regression models were used to identify variables associated with insomnia or sedative-hypnotic use. Key findings include low insomnia diagnosis rates (3.5–5.6%) and high rates of sedative-hypnotics (44.2–49.0%). Younger Veterans and those without a breathing-related sleep disorder (BRSD) were more likely to receive an insomnia diagnosis. Veterans with greater service connection and those with an alcohol/substance use disorder were more likely to be prescribed sedative-hypnotics. Interaction terms may have identified potential groups at risk of being under-diagnosed with insomnia (i.e. non-black Veterans with psychiatric co-morbidity, black Veterans without psychiatric co-morbidity) as well as groups at risk for sedative-hypnotic use (i.e. younger Veterans without BRSD). In sum, Veterans with PTSD have high rates of sedative-hypnotic use despite minimal evidence they are effective. This is counter to recommendations indicating behavioral interventions are the first-line treatment. Policy changes are needed to reduce use of sedative-hypnotics and increase access to behavioral insomnia interventions.     

防空兵指挥决策系统及其运行环境的影响

决策者、决策辅助人员和指挥决策信息系统是部队指挥决策系统的基本组成部分,防空兵指挥自动化和决策支持系统则是指挥决策信息系统的一部分,环境因素和决策信息是影响防空兵指挥决策系统的重要因素.从系统的观点阐述了防空兵指挥决策系统与内外环境因素的关系,提出在新技术条件下,系统信息是防空兵指挥决策系统的又一组成要素.从这个观点出发,可以准确、全面地了解和分析系统环境因素对防空兵指挥决策系统影响,最终达到提高防空兵指挥决策效能的目的.
