现代高校教师的劳动特性与人性化管理问题探析

"人性化管理"是由现代行为科学演变出来的一种新的管理概念,随着知识时代的来临,人作为知识、智慧的主体变得越来越重要,而高校是人才聚集之地,如何合理开发人的内在潜能,已成为新形势下高校人事管理部门研究的重要课题。本文分析了高校教师劳动特性并对高校教师人性化管理的问题进行了探析,对人事制度改革过程中的教师管理问题具有一定的指导意义。     

一种非对称鲁棒性盲水印算法

针对数字图像版权保护,提出一种非对称鲁棒性盲数字水印方法。通过将水印嵌入到最少受图像改变影响的子空间,使嵌入水印具有鲁棒性,且通过对特征子空间的选取限制,使算法具有较高的检测概率和安全性以及较低的虚警概率。同时,水印嵌入矩阵与提取矩阵不同,它可公开除密钥外的所有其它的信息,而且能实现水印盲提取。实验结果证明了该算法的鲁棒性。     

舰载武器作战使用条件仿真量化分析

运用层次分析法、本征向量法和多属性决策问题的数据处理等方法,对舰载武器作战使用的约束条件进行了量化分析和数据处理,系统地描述了单一约束条件和多个约束条件对武器有效使用的概率问题,建立了约束条件下,舰载武器作战使用仿真流程。研究结果对舰载武器作战使用具有一定的指导作用。     

Rényi信息增量和协方差联合控制的多传感器管理算法

针对目标跟踪中雷达组网场景下多传感器管理问题,结合Rényi信息增量和协方差两种算法各自特性,利用并行处理的思想提出了一种基于Rényi信息增量和协方差联合控制的传感器管理算法。在具体仿真设计环节,分为传感器跟踪能力大于目标数和传感器跟踪能力小于目标数两种场景。仿真结果表明该算法在单目标匀速、多目标匀加速等多数场景下能够对目标进行有效跟踪,同时降低了传感器的切换频率,具有更好的实时性。     

基于灰色加权马尔科夫的部队集成训练效果预测

针对GM(1,1)预测模型误差较大的问题,在GM(1,1)模型的基础上引入加权马尔科夫模型构建了部队集成训练效果预测模型。该模型以GM(1,1)模型存在的预测残差作为划分马尔科夫状态的依据,通过加权处理对预测结果进行修正。实例分析结果表明,该模型算法简单,易于实现,可以较大地提高部队训练效果预测精度,为部队开展科学有效的实战化训练提供了有力的数据支撑。     

Leadership and national security: an interrogation of the Boko Haram violence in Nigeria

This study contends that an analysis of the nexus between leadership and security offers useful insights into explaining conflict by stating that the conceptualisation of these argots, especially through the definition of leadership as a process, helps to explain and address Nigeria’s security challenges. By arguing that leaders’ ability to establish mutuality with their followers in any situation and set collectively-generated means for attaining these set goals for societal security, the study shows how such a relationship creates a secured state. This is not the case in Nigeria, where leaders’ security decisions are influenced by external actors rather than by their followers. By showing that the Nigerian ruling elite’s security agendas intersect with dominant global notions of security while neglecting genuine security interests of ordinary Nigerians, the study contextualises the complex global and local security interests in Nigeria. The lack of an intersection at home, however, has contributed to the emergence of extremists such as the Boko Haram sect, as well as the escalation of the acts of violence they perpetrate. As national insecurities become complex and intractable, ‘elegant’ or unilinear solutions – such as a military approach – lack the capacity to address these problems.     

Too much Western bias? The need for a more culturally adaptable approach to post-conflict security sector reform

The existing guidelines for security sector reform (SSR) tend to draw on theoretical work in the field of civil–military relations, which in turn has been derived from Western, liberal democratic models of governance. Although guidelines strongly advise that local culture and context need to be considered when drawing up objectives for post-conflict SSR programmes, this is not often reflected in practice. This article considers some of the reasons for this, citing both in-country challenges and donor-related issues, and suggests that one of the biggest problems is a lack of alternative, non-orthodox models of civil–military relations to draw upon. It is further suggested that elements of suitable alternative models may be found in states which possess political structures not entirely dissimilar to the Western, liberal democratic ideal, but which can offer different perspectives. Detailed research of these structures should produce a pool of sub-models which could then be employed to create bespoke, culturally appropriate objectives for use in post-conflict SSR programmes.     

“Effing” the military: a political misunderstanding of management

The use of commercial business management techniques is widespread in all government departments, including the Ministry of Defence. This article examines the use of popular management techniques in the Armed Forces and argues that their application is misplaced. It looks at what the “effs” – “efficiency” and “effectiveness” – mean in the business world and to the Armed Forces. It compares the definitions both in business and the Armed Forces and finds that there are few, if any, situations where the same measurements can be applied. Whilst many management techniques are suited for business, the function of the Armed Forces and its output cannot be measured in the same way, complicated by the different metrics of “efficiency” in peace and in war. This difference may not be clearly understood by some politicians, or indeed by some senior military personnel. Using examples from some of the most popular management techniques such as “Lean” and “Agile” it is possible to see that their use might actually diminish the capabilities of the Armed Forces when it comes to performing their principal role – the use of force to achieve political objectives.
