两级信息融合技术在柴油机故障诊断中的应用

针对传统神经网络在故障诊断中因测点信息多而导致的网络庞大、收敛困难等问题,引入集成神经网络,提高了融合诊断效率;同时引入基于D-S证据理论,这种决策融合方法解决了集成神经网络各个子网诊断结果不一致的问题。在应用于柴油机故障诊断时,首先对测取的正常和故障样本进行小波包AR谱分析,同时提取各个特征频带的能量分别作为集成神经网络对应子网的输入进行诊断,当其无法确定诊断结果时,再运用证据理论进行决策融合输出最终诊断结果。试验证明:基于集成神经网络和D-S证据理论的两级综合诊断模型提高了诊断的准确性和可靠性。

Rethinking strategic culture: A computational (social science) discursive-institutionalist approach

ABSTRACT

The strategic culture approach has been suffering from a prolonged theoretical stalemate, despite a surge in case studies, which culminated in the Johnston-Gray debate and subsequent schism. The present paper outlines a new approach designed to overcome this deadlock, and consists of three arguments. First, the three previous generations of strategic culture studies have failed to explain how strategic culture influences behaviour. Second, aligning strategic culture theory-building with discursive institutionalism offers a way to overcome this fundamental fallacy. Third, a research programme for strategic culture should draw on computational social science to enable it to present and test middle-range theories.     

以多元智能理论为指导的大学英语教学模式探析

The struggle of a Kantian power in a Lockean world – German leadership in security and defence policy

ABSTRACT

German security and defence policy has undergone substantial transformation. This transformation requires an unprecedented level of political leadership, suggesting that Germany needs to solve the dilemma of how to supply leadership to increasingly demanding partners. What are the conditions under which German leadership can unfold in security and defence policy? To what degree do German role-conceptions of international agency and role-expectations of German leadership coincide? What kind of leadership outputs are produced? This study offers a comprehensive analysis of German security and defence policy in terms of supply (role conceptions) and demand (role expectations). We outline three leadership role conceptions present in the German strategic debate, which we then assess in the context of the Wendtian theory of cultures of anarchy. We then analyse Berlin's leadership in terms of outputs via the case study on Anchor Army and the Framework Nations Concept. We conclude that while Germany has tried to match leadership role expectations both rhetorically and in action, Berlin's leadership inputs have so far been insufficient. This has led to an imbalance in terms of role conceptions and expectations hampering effective German leadership in security and defence policy.     

Rose-tinted lenses: how American functionalist strategy inhibits our appreciation of complex conflicts

Strategists and military professionals have previously questioned many of the methodological (theoretical underpinnings, the principles, and rules applied by the discipline) decisions associated with American military strategy, but the direction this essay takes is above and beyond the common methodological rivalries in how we pursue strategic desired future states. To get beyond methodological disputes entirely, we must consider thinking about our thinking as an organization on American strategy. Thus, this article hovers between philosophies, organizational theory, as well as our usually unquestioned belief in something called “strategy”. Questioning things about our basic understanding of the world tends to trigger strong organizational defense mechanisms, for good reason. Critical reflection at deep levels puts our worldview, and our role within it at stake. Nonetheless, as strategic disappointment emerges over multiple complex conflict developments, even the most cherished and guarded choices on how the world ought to work are ripe for critical inquiry. This essay examines the limited single strategic paradigm of the US defense industry and how the latest American National Security Strategy and Army Future Operating Concept (Win in a Complex World through 2030) presents a flawed strategic position. This essay presents valid alternative strategies that operate within different paradigmatic constructs.     

政府重塑理论在消防管理中的应用

利用政府重塑理论分析了我国消防管理模式的现状，指出近几年我国消防管理体制改革的思路和方向正是政府重塑理论所倡导的强调效率、注重“掌舵”而不是“划桨”的管理模式。针对我国现行消防管理体制存在的政府职能发挥不足、消防安全责任不明确、体制不顺的问题，结合我国国情和消防工作特点，借鉴政府重塑理论的思想精髓，提出了构建一个既“掌舵”又“划桨”的、充满竞争活力的、受效果驱动的、“企业行政”式的消防管理模式的改革思路。

Forces of heresy versus forces of conservation: making sense of Hezb-e Islami-ye Afghanistan’s and the Taleban’s positions in the Afghan insurgency

Ethnicity and ideology are frequently used to determine whether an armed group is hostile or friendly vis-à-vis the state. By contrast, I argue that the social structure of insurgent movements holds more explanatory power for their respective positions than ethnicity or ideology. To illustrate this, I apply Pierre Bourdieu’s concept of a contest between forces of ‘conservation’ and forces of ‘heresy’ to the current Afghanistan war. I demonstrate that the social structure of the Taleban renders them prone to ‘heresy’, while the formerly second biggest insurgent group, Gulbuddin Hekmatyar’s party, has rather been an impeded force of ‘conservation.’
