新疆高校地方特色课程对大学生文化观的影响研究

《新疆历史与民族宗教理论政策教程》是最具有中国特色、新疆地方性特色的课程,开设此课的目的是为了提高大学生思想、牢固树立马克思主义"五观"理论。为了解课程对大学生文化观的教育效果,选取民族班大学生进行研究发现,课程开设后,少数民族大学生的多元文化观显著提高了。居住格局、家庭语言交流类型、上大学前的学习模式等个体变量会影响文化观的提高程度。     

The politics of renewed quest for a Biafra Republic in Nigeria

The quest for a Biafran Republic by the Igbo ethnic group has become a recurring demand in Nigeria since the late 1960s. The agitation has been premised on claims of marginalisation and exclusion of the Igbo people in the Nigerian body politic. In spite of the consistency of the agitation through various Administrations, there was a noticeable lull in such demands during the time of President Goodluck Jonathan, only to assume a frightening proportion since the advent of the Administration of President Muhammadu Buhari. This article locates the factors in the outcomes of the 2015 general elections: the question of inclusion and representation; the unfinished nature of the Nigerian civil war; economic challenges, miscalculation both on the part of the Igbo people and indiscretion in the initial appointments made by President Muhammadu Buhari. The article recommends political restructuring of Nigeria as one of the ways to address secessionist tendencies.

舰船复合材料局部结构细节设计方法

由于复合材料结构具有各向异性、组份复杂、可设计变量多等特性,有效的复合材料结构设计应同时考虑整体结构宏观设计和局部结构细节设计,两者虽密切关联,但在分析方法上存在一定差异。对此,将整体结构简化分析与局部结构细节设计联系起来,重点针对局部结构细节设计方法进行探讨,提出了一种细节设计方法。该方法基于子模型与试验工况模型的对比分析,通过局部结构试件试验对整体结构承载特性进行了综合评价。以某型船复合材料甲板室结构设计为例,通过整体简化模型优化分析确定板架构件尺度参量和铺层设计方案;提取典型局部结构承载形变特征要求,并基于子模型分析技术探讨局部结构细节设计;最后,以局部结构试验验证与考核完成整体结构的优化设计。计算结果表明:该方法能在有效控制设计成本的同时,合理开展复合材料结构设计工作,可供研究和设计者参考。     

Effective in battle: conceptualizing soldiers’ combat effectiveness*

How do we understand combat effectiveness – soldiers’ performance in battle? Despite the broad consensus that understanding combat effectiveness is important both for scholars and policymakers, there is widespread disagreement about what combat effectiveness is. More specifically, studies of effectiveness tend to focus on either the skill of soldiers in battle, or their will to fight. Yet both skill and will are essential components of an effective fighting force. This article argues that understanding combat effectiveness requires understanding both of these key components of effectiveness. In other words, combat effectiveness requires both the skill and will to engage the enemy in an organized manner. It then demonstrates the usefulness of this conceptualization by applying it to the cases of British, Indian, and Australian forces fighting the Japanese during the Second World War. Only when scholars are talking about the same concept will our understanding of the conditions under which militaries are effective in battle progress. By comparing different units fighting the same opponent under the same material conditions, I demonstrate that units vary both in their combat skill and their will to fight, and that understanding their effectiveness in battle requires analyzing both of these key factors.

基于混合算法的局部路径规划

人工势场法是一种常用的具有算法简单和便于实时控制的局部路径规划方法,但存在容易产生局部极小值的问题。基于模糊逻辑的局部路径规划法具有环境适应性强等优点,它在连续论域内采用模糊路径规划时,计算量比较大。提出了一种将人工势场法和模糊逻辑法相结合进行局部路径规划的混合算法。具体方法是在一般情况下采用人工势场法进行局部路径规划,当产生局部极小值时,采用模糊逻辑法进行局部路径规划。仿真结果表明,该方法能有效地解决局部极小值问题,给智能车规划出光滑的路径。
