Defense–Growth Causality: Considerations of Regime-Switching and Time- and Country-Varying Effects

This paper develops a panel smooth transition vector autoregressive model to investigate the economic growth–defense causality. This model simultaneously resolves the estimation problems of endogeneity, heterogeneity, and nonlinearity. Empirical results support that the causality is bidirectional, nonlinear, time- and country-varying. Economic growth has a negative impact on military spending and vice versa. The larger the HDI, the smaller the negative causality. Evidently, the increase in the level of country development can reduce the negative impact of military outlays on economic growth. Reducing the ratio of military spending to GDP is beneficial for countries with low HDI scores; however, moderately increasing the share of military expenditure is favorable for countries with extremely high HDI scores. Policy authority needs to set optimal education, health, and economic development shares of GDP for purchasing a maximum economic growth rate.     

基于BP神经网络的UCAV航迹综合评价

OTHER-THAN-INTERNET (OTI) CYBERWARFARE: CHALLENGES FOR ETHICS,LAW, AND POLICY

Almost all discussions of cyberwarfare, other cyber-attacks, and cyber-espionage have focused entirely on the Internet as the chief means of damage – the Internet as a ‘vector,’ using a term from the theory of infectious diseases. However there are a variety of means, some of which have already been used, that involve cyber-exploitation using vectors other than the Internet. Malware can be installed in the integrated circuits of computers and servers, but also in any devices attached to them – thumb drives, CDs, printers, scanners, and so on. One can also use various forms of electromagnetic radiation at a distance of meters or more to exfiltrate data or to infiltrate corrupt data. I call this large and diverse family of unwanted interference with the functioning of information processing systems other-than-Internet (OTI) attacks on information systems. Stuxnet, and probably the 2007 Israeli corruption of Syrian air defenses, were OTI attacks. Such OTI techniques are more difficult to develop than creating malware, requiring electronic manufacturing facilities or novel technologies, and are thus accessible only to larger corporations and technologically sophisticated countries. Particularly vulnerable would be countries (like the United States and Europe) whose information processing devices are mainly produced outside of the country. Once exploitations via the Internet become harder to perpetrate, OTI exploitations are certain to grow dramatically, eventually requiring equipment for critical uses to be expensively fabricated in (and transported using) secure facilities; expensive detection measures will have to be instituted. This will create challenges for policy, law, and ethics, as well as greatly increasing the cost of many electronic devices.     

海上远程精确打击体系作战能力评估指标空间建模方法研究

现代战争的信息化程度、复杂性和不确定性不断提高,对海上远程精确打击（LPSS）体系作战能力的评估提出了更高的要求．要想准确评估系统的作战能力,建立合理的LPSS体系作战能力评估指标体系非常关键．然而影响LPSS体系作战能力的指标繁多,指标间存在冗余和相关性,不同层次指标间还存在交叉性,直接采用这些指标会增加后续评估的时空复杂度．在创建LPSS体系作战能力评估指标体系的基础上,对评估指标空间的建模方法进行研究,创建了可供评估的数据样本空间,为后续对底层指标集合进行约简、降维处理奠定了基础．
