The concept of the command of the sea has its roots in medieval notions of the sovereignty of coastal waters, as claimed by several monarchs and polities of Europe. In the sixteenth century, a surge of intellectual creativity, especially in Elizabethan England, fused this notion with the Thucydidean term ‘thalassocracy’ – the rule of the sea. In the light of the explorations of the oceans, this led to a new conceptualisation of naval warfare, developed in theory and then put into practice. This falsifies the mistaken but widespread assumption that there was no significant writing on naval strategy before the nineteenth century. 相似文献

In the South China Sea, China neither implements power-maximizing policy nor engages a peaceful approach. Instead, China implements both coercion and cooperation in pursuing its strategic interest in the disputed area. How can we explain China’s paradoxical behavior? This article claims that the best way to explain China’s policy in the South China Sea is to understand the character of dualism in China’s strategic culture. Following constructivist theory that stresses culture, this article argues that Chinese duality approach in the South China Sea is rooted in the philosophy of Daoism. The symbol of Yin-Yang depicts Chinese assertive as well as cooperative behavior in dealing with the South China Sea dispute. Although from a normative perspective Daoism recognizes pacifism and non-violent behavior, the most important feature of Daoism is the assumption that reality consists of two opposing elements that are mutually embedded. 相似文献

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO. 相似文献

Hamilton系统是非线性科学中的一个重要领域,很多人在超二次或次二次条件及其他一些条件下对Hamilton系统的周期解进行了研究。此文则研究了非自制二阶Hamilton系统在零点局部环绕及“非二次”条件下周期解的存在性,并利用局部紧性条件(C)条件以及极大极小方法证明了其周期解的存在性。 相似文献
