Poland's national potential and its international position within the European Union – research remarks

This article examines Poland's national potential and its international position within the European Union (EU) with respect to security issues. It presents research results based on a comparison of Poland's national potential as it relates to other EU countries, which is useful when evaluating Poland's power within the EU. The article also evaluates Poland's crisis potential, i.e. it identifies those factors that may potentially be treated as threats to national and regional security. Finally, it enables the identification of challenges to Poland's security in the second decade of the twenty-first century. The research is conducted according to a multidimensional comparative analysis, which is perceived by the author as the best available to measure a country's power despite its weaknesses.     

近年来军事法学若干基础理论问题研究述论

矛盾及其化解：军事法的部门法地位解析

中国特色社会主义法律体系业已形成,军事法的部门法地位问题却再度引发热议,我国法律体系相关理论构建过程中未及解决和完善的各种理论缺陷和逻辑谬误再度显现.理论上的矛盾需要化解,在我国特殊的宪政体制已经预设了军事法体系独立地位的前提下,军事法的部门法地位应当得到普遍认同.而为了达到这一目标,我国社会主义法律体系理论的完善成为必需,对军事法部门法地位的逻辑解析成为必要。

Witchcraft and African development

Impressive investment and growth figures and commercial write-ups enthusing about ‘Africa rising up’, ‘the continent of the future’, and so on, obscure the poverty, illiteracy, poor health and other hardships afflicting the vast majority of African people. Why has massive so-called development and technical ‘aid’ not created the expected dynamic, autonomous economic progress? A blind eye is delicately being turned to the decisive role of people – more specifically, the cultural element. Notwithstanding good intentions, outsiders seeking to promote development assume that black Africans think and act like they only need more education, training and finance in order to ‘catch up’. Outsiders easily forget that since time immemorial, Africans have developed and cherished worldviews and cultures of their own. While these are by no means immutable and do adapt to changing needs and outside influences, Africans refuse to cast off overnight the heritage that makes them the people they are. This paper examines the impact of witchcraft as an integral feature of traditional culture on African existence, notably community life, religion, politics, the law, and economic practice. It stresses the significance of traditional society's powerful egalitarian impulses as well as its profound conviction that all things – goods, wealth, well-being and life force – are in a strictly limited supply that cannot be increased, but can only be redistributed by force or through magical manipulation. While modern life gradually weakens the influence of witchcraft beliefs – in Europe these flourished well into the 18th century – the exasperation associated with Africa's headlong urbanisation actually bolsters these beliefs.     

美军战略传播的发展特点及启示

Counterinsurgency or irregular warfare? Historiography and the study of ‘small wars’

This article argues that the history of irregular warfare provides a valuable analytical and critical perspective for the study of counterinsurgency campaigns and counterinsurgency doctrine. A focus on the history of irregular warfare highlights the close relationship between warfare in Europe and in the colonies. Moreover, it enables us to identify more exactly the intersection of multiple factors that lead to an escalation of violence in small wars. Finally, it also sheds light on the lack of strategic reflection on the use of irregular auxiliaries that is characteristic for many counterinsurgency campaigns.     

月球返回舱再入制导律设计

针对以接近甚至超过第二宇宙速度再入地球的登月飞行器制导任务,研究了满足热流、过载、落区等约束的返回舱再入制导律。月球返回舱是低升阻比弹道升力式再入飞行器,控制策略是改变倾侧角的符号和大小。倾侧角大小的确定转化为一个单变量非线性方程求根的问题,倾侧角符号的确定依倾侧反转逻辑来满足横向走廊,其中横向走廊设计成速度的函数。通过综合偏差的Monte Carlo仿真评价制导算法的性能,仿真结果表明制导的纵向标准偏差在30km左右,横向标准偏差小于5km。此外,分析了影响滚转速率的因素,给出了调整反馈增益系数和减小滚转速率及制导精度的关系。     

平底气泡船凹槽气层波动特性

为提高大型平底气泡船底部凹槽设计的有效性,基于RANS方程及VOF两相流模型构建了大型平板船凹槽气层数值计算模型。研究气层在凹槽中的动态发展过程,分析速度对气层波动的影响规律,并阐述三维凹槽气层的波形特性及其与二维气层波动的区别,揭示气层波动的相似律。数值结果表明:气层在凹槽中呈现波动形态,气层波长随速度的增加而增大,波长等于速度平方的0.64倍;气层在凹槽侧壁的干扰及反射下呈现相干波系,从而其波高及局部厚度也随之改变;气层波动满足傅汝德相似。
