针对传统AHP在实际应用中存在的问题,采用三标度法进行潜艇兵力作战方案的多目标优选决策,避免了采用九标度方法构建判断矩阵时权重选择的模糊性,从而减少了决策过程中决策者的主观臆断性.实例证明,三标度法具有简单明了、使用方便等优点,在应用于作战方案多目标决策等复杂系统时是适合可靠的. 相似文献

本文采用1961—2001年石河子地区的气象资料,利用奇异谱分析的方法,分析了40a来气温变化,结果表明,石河子的气温变化具有4个明显的变化周期,分别为33—34年,11—12年,8—9年,3—4年;利用噪声驱动阻尼振子模型对得到的时间周期做了初步的分析,并利用拟合函数集对石河子气温给出了对应的函数变化关系。利用该方法可以对气温的变化特征有一个明晰的物理理解,也可以为将来的气温变化趋势的预测给出一定的借鉴作用。 相似文献

This article interrogates the continuing relevance of the contractarian governance paradigm to resource governance and the impact of exploitation on the local population and environment in the Democratic Republic of Congo (DRC), Zimbabwe and Ghana. It highlights the susceptibilities of their governance processes, particularly the roles of the elites of the host communities, the multinational corporations, and the governing authorities in appropriating resources for their personal interests, resulting in tensions and conflicts. This scenario is borne out of inept leadership, as well as the defective and compromised administrative mechanisms operational in these countries. In view of this, the article underscores the need for a ‘new governance management paradigm’ anchored on a communitarian framework, which incorporates all stakeholders, to guarantee sustainable peace and prosperity, particularly in conflict zones. The article therefore concludes that achieving a nexus between forestry, mining activities and economic development in these countries will require a restructuring of the existing governance mechanisms; and advocates for a new governance model capable of curbing the excesses of local and foreign hegemony, including a total overhaul of the seemingly compromised supervising authority. 相似文献

This article sets out to investigate the current paradoxical roles of border control agencies in order to contribute to the theoretical debate on border porosity and related security issues in West Africa. The colonial demarcation of African borders accounts for their porous nature initially, as borderland populations challenged the unjust scission of their cultural, economic, geographical and geopolitical spaces. However, new forms of porosity also evolved over time, masterminded by new actors. Drawing on the Ghana–Togo border case, and through interviews, observation and documentary analysis, this article argues that border control agencies are partly responsible for the current border porosity and attendant security problems as their jurisdiction has shifted to a multi-layered border parasitism. The article is not, however, an attack on border law enforcement agencies; rather it attempts to explore their roles in shielding the region, already exposed to terrorism and piracy, from further security threats. 相似文献

现代战场空间可划分为“地表(陆地、海洋)、垂直(航空、航天)、网电(电磁、网络)”等“三维六域”,多维战场空间优势可迅速转化为战斗力优势。为夺取空防对抗战场空间优势,空防对抗战场拓展到网电空间,夺取“制网电权”成为夺取“制空权”与“制天权”的前提;来自空袭方的网电攻击,是未来国家防空面临的又一严峻威胁,也是信息化条件下必须应对的新课题。空袭与防空在网电空间的对抗,将对未来防空作战指导、作战样式以及作战建设等产生重大影响。 相似文献

This paper examines the rationale and centrality of private military and security companies (PMSCs) in humanitarian assistance operations in Sudan, asking why PMSCs are involved in humanitarian assistance operations in Sudan and what the principles underlying their activities are. To answer this question, the paper draws attention to the link between humanitarian crises and PMSC interventions. Where there is no meaningful alternative intervention, undergirded by humanitarian concerns that are also profit driven, PMSCs come in to provide the needed services. The protracted and complicated internal armed conflicts in Sudan, which have lasted for over two decades, have produced as many as 4,8 million internally displaced persons (IDPs) – the single largest number in the world. The kind of humanitarian assistance operations provided by PMSCs in Sudan have become critical to the provision of much-needed services which were inadequately provided by governmental authorities at both unilateral and multilateral levels. This paper argues that the humanitarian crises in Sudan created a regime that permits humanitarian assistance operations by both state and non-state actors. 相似文献

对来袭空中目标的威胁进行评估与排序是舰艇对空火力分配的重要一环。根据来袭空中目标的特点,在确定目标指标后进行相应量化,针对来袭目标各指标间非线性的特点,提出使用核主成分分析法对目标信息进行特征提取,随后依据核主成分方差贡献率对威胁目标进行评估与排序。通过仿真算例验证,所得结果较为准确、客观,有效地克服传统方法中主观性较强的问题,并且在对指标数据提取的过程中降低了相关信息维数,降低了计算复杂度,为舰艇防空作战威胁评估提供了新途径。 相似文献

生命教育是以学生生命过程和价值为本的教育理念,这种教育理念认为:教育的主题是艺术地生活、教育的目的是培育活跃的思维、教育的过程就是生活探险的过程。我们迫切需要转变目前的规训教育模式,将教育回归到人之中,从学生主体内在生成过程的视角去理解教育过程,努力寻求和建立一种追求生命价值的教育模式。 相似文献

本文基于新疆九所高校大学生就业意愿的调查数据,利用多元logit模型对大学生省域就业选择意愿及影响因素进行了实证分析。研究结论如下:民族特征显著影响大学生省域就业选择意愿,大学生更愿意到生源地和就读高校所在地就业。省域内就业选择主要受民族、生源地以及父母是否在南疆地区工作等因素的影响。省域外就业流动会受到家庭因素的影响,家庭资本积累越低越不倾向选择到疆外地区就业。新疆高校就读的大学生,尤其是汉族和生源地为疆外地区的大学生,呈现出更愿意到疆外地区就业的流动特征。 相似文献

进入21世纪特别是“9·11”以后,恐怖袭击的阴云一直笼罩着整个世界,让很多人谈恐色变。急剧升级的恐怖活动使全世界感到震惊,恐怖袭击已经升级为一场看不到对手也没有明确战线却让人防不胜防的特殊战争。一、袭击目标非常明确,难以料想作为战争都有自己明确的作战目的,恐怖袭击也一样。从“9·11”到刚发生的俄劫持人质事件,恐怖分子的目的非常明确,就是通过制造混乱和破坏正常秩序进行复仇与抗议。他们在袭击前选定的目标往往非常明确,而且几经筹划,秘密进行。作为被袭的一方均蒙在鼓里,一个是未雨绸缪,一个是一无所知,所以防不胜防。如“… 相似文献
