The impact of military spending and income inequality on economic growth in Turkey

An extensive literature on the effect of military expenditures on economic growth yields conflicting results. However, a crucial issue that has not been investigated in this context is the possible effect of inequality. The impact of military expenditures on economic growth in Turkey has also received substantial attention. Yet, the majority of these studies are not constructed based on a structural model, but rather examine the causality between the variables in question. Considering these two shortcomings in the literature and the lack of consistent results, this study attempts to provide further evidence for the relationship between military expenditures and economic growth for the case of Turkey by considering income inequality within an augmented Solow growth model. Our findings for the 1963–2008 period show that while income inequality has a positive impact on economic growth, military expenditures have no significant effect.     

Militarism in post-war Cyprus: the development of the ideology of defence

This article provides a theorisation of militarism in post-war Cyprus. Based on qualitative empirical research conducted in Cyprus in 2011, the article explores the manifestation and steadfastness of Greek-Cypriot militarism, and the development of this militarism, which appeared after the partition of the island in 1974. In particular, it proposes the ideology of defence as a way to understand post-war Greek-Cypriot militarism. It shows the embedded nature of defence in the idea of the national struggle. It aims at mapping the character of this militarism in order to provide the grounds for future discussion. Only by understanding the interconnecting discourses that made Greek-Cypriot militarism possible in post-war Cyprus, can we understand its past, present, and future.     

周恩来建设人民海军的理论和实践

周恩来协助毛泽东开创了中国人民海军事业。他高瞻远瞩,为人民海军的创建发展做好顶层设计;他呕心沥血,制定新中国海军建设的战略规划;他事必躬亲,操劳着海军建设方方面面的具体事项;他英明善断,指挥部署人民海军重要战役和重大行动。他对创建和发展年轻的共和国海军,作出了不可磨灭的贡献。周恩来建设人民海军的理论和实践,对今天的海军建设仍具有重要的理论价值和实践意义。

聚类分析是数据挖掘中的重要技术.在比较分析了两种常用的聚类分析方法的基础上,将基于商空间的非均匀粒度聚类算法应用于雷达信号分选中,仿真实验的结果表明:该算法可以从不同层次观察聚类数据,更适用于复杂雷达信号聚类分选,具有良好的性能.     

基于时间融合的雷达辐射源自动识别方法

雷达辐射源识别是雷达对抗信号处理中关键环节,也是电子目标识别的重要前提.介绍了Dempster组合规则和加权M-距离法、灰关联分析法等时间融合的雷达辐射源自动识别方法,提出了基于证据理论的单传感器时间融合算法,研究了单传感器在不同时间测量周期的证据综合过程,并给出仿真试验结果.随着噪声的增大,传感器单次时间融合的正确识别率下降很快,而采用基于D-S证据理论的单传感器时间融合方法却有较高的正确识别率,该算法大大降低了错误识别率.因此提出的算法是可行的.     

基于DEM的机载C3I指控系统效能评估

随着科学技术突飞猛进的发展、武器更新换代的速度加快,系统效能评估的方法不断被提出和采用.提出了一种以系统空间与使命的匹配程度为目标的动态评估模型的评估思想,该方法在一定程度上能弥补由于使命属性选择不够合理而导致对评估产生的差异.其评估结果表明了机载C3I指控系统试飞达到了预期的目标,各指标都符合设计要求.     

Optimal timing of switches between product sales for sports and entertainment tickets

Like airlines and hotels, sports teams and entertainment venues can benefit from revenue management efforts for their ticket sales. Teams and entertainment venues usually offer bundles of tickets early in their selling horizon and put single‐event tickets on sale at a later date; these organizations must determine the best time to offer individual tickets because both types of ticket sales consume the same fixed inventory. We model the optimal a priori timing decision for a seller with a fixed number of identical tickets to switch from selling the tickets as fixed bundles to individual tickets to maximize the revenue realized before the start of the performance season. We assume that bundle and single‐ticket customers each arrive according to independent, nonhomogeneous Markovian death processes with a linear death rate that can vary over time and that the benefit from selling a ticket in a package is higher than from selling the ticket individually. We characterize the circumstances in which it is optimal for the seller to practice mixed bundling and when the seller should only sell bundles or individual tickets, and we establish comparative statics for the optimal timing decision for the special case of constant customer arrival rates. We extend our analytical results to find the optimal time for offering two groups of tickets with high and low demand. Finally, we apply the timing model to a data set obtained from the sports industry. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2008
