高职生“学习参与度”对创新创业核心素养的影响机制研究

通过对523名高职学生进行实地调研,探析“学习参与度”对学生创新创业核心素养的影响机制。结果显示:课程建设、教师引导、资源支持对学习心理参与度影响显著;教师引导、资源支持、社会实践对学习行为参与度影响显著。学习参与度显著影响创业意识、创新精神、创业能力。提出优化对策:重视学生创新创业核心素养的培养;提高学生创新创业学习参与度;人际互动提升学习心理参与度;协同培育提高学习行为参与度。     

剃齿时齿形中凹现象的形成机理

本文综合啮合原理、微分几何和弹性力学的基础理论,对剃齿过程中刀具齿面和被剃齿轮齿面间的失配进行了分析。最后利用径向力求出了齿面间的压切量,从而解释并验证了剃齿过程中产生的齿形中凹现象。这对提高剃齿精度、降低噪音有着重要意义。     

Between meaning culture and presence effects: contemporary biomedical objects as a challenge to museums

The acquisition and display of material artefacts is the raison d’être of museums. But what constitutes a museum artefact? Contemporary medicine (biomedicine) is increasingly producing artefacts that do not fit the traditional museological understanding of what constitutes a material, tangible artefact. Museums today are therefore caught in a paradox. On the one hand, medical science and technologies are having an increasing pervasive impact on the way contemporary life is lived and understood and is therefore a central part of the contemporary world. On the other hand, the objects involved in medical diagnostics and therapies are becoming increasingly invisible and intangible and therefore seem to have no role to play as artefacts in a museum context. Consequently, museums are at risk of becoming alienated from an increasingly important part of contemporary society. This essay elaborates the paradox by employing Gumbrecht’s (2004) distinction between ‘presence’ and ‘meaning’.     

一种基于DIS/HLA仿真的空对地作战效果评估方法

Action Research for Sustainable Water Futures in Western Sydney: Reaching Beyond Traditional Stakeholder Engagement to Understand Community Stakeholder Language and Its Implications for Action

Action on issues of ecological significance often requires changes in personal behaviour and political consensus on technologies to support these changes. Unfortunately, many consultation processes only engage a narrow range of stakeholders, usually those professionally engaged or already active on a range of community issues. This paper illustrates how people who are ‘hard to reach’ or seen as ‘apathetic’ might be engaged using ‘action-conversations’ that explore the social climate for action and how scientific/technical messages can be framed in the language of the community.

基于JMASE的地空导弹联合建模与仿真

以六自由度地空导弹拦截仿真为背景,阐述联合建模与仿真环境(JMASE)的基本概念和功能描述,介绍基于JMASE-SIMULINK的工程级与交战级一体化联合建模与仿真方法,给出某地空导弹全系统模型及交战仿真结果。仿真实践表明:通过将SIMULINK模型自动转换为JMASE兼容的C 模型组件,并在JMASE环境下组装、配置和运行,则获得SIMULINK工程级武器系统建模能力的同时,也获得JMASE提供的具有一致时空及环境效应描述的交战级仿真能力,既提高了建模与仿真的效率,又促进了模型重用和互操作,是实现工程级与交战级联合建模与仿真的有效方法。
