舆论自由与司法公正的平衡探析

舆论自由和司法公正是现代社会的两种重要价值取向。舆论自由是一项基本的宪法权利,传媒的力量无疑推动着我国民主进程的发展;司法公正亦是社会主义法治的基本要求,有助于促进公平正义秩序的建立。随着我国现代化进程的逐布推进,大众传媒在信息量和速度方面有着惊人的进展,对司法结果甚至是司法过程都可以进行同步的舆论监督,但不可忽视的是,两者之间的不协调和矛盾因素也日益凸显。应重在制衡彼此的关系,促进社会正义的实现。     

康德的哲学革命与先验自由观

康德开创了理性的、批判的哲学革命体系。"前批判时期",康德的哲学革命首先是在自然科学领域进行的,打破了当时占统治地位的僵化自然观;"批判时期",他又以理性思辨在认识论、伦理学领域综合唯理论与经验论、幸福与道德,继续推进其哲学革命,表达了他整个批判哲学所关注的四个问题。康德通过纯粹理性批判提出了先验自由概念,通过实践理性批判以及历史和政治理性批判确立了先验自由观念。康德在星空上与心灵中进行的哲学革命蕴含着社会政治革命的巨大能量,具有崇高境界。     

基于逆虚拟激励法的车辆动载的识别

采用逆虚拟激励法进行车辆行驶随机动载的识别,使用确定性方法求解了车辆平稳行驶动载的识别问题.即已知车辆振动响应的自谱与互谱,在反求路面激励功率谱的基础上,求出车辆行驶动载.并通过计算机模拟识别动载.研究结果表明,根据前轮的响应模拟出的车辆随机动载能较好地反映车辆在不同速度,不同路面上的变化.逆虚拟激励法在求解车辆随机动...     

What are universities for?

Governments worldwide rightly regard universities as fundamental to the achievement of many national priorities. But it is the paper’s contention that many misunderstand their true benefit to society. Investments in universities are increasingly based on the belief that the science labs in particular of research-intensive universities can be the source of a continuous stream of people and ideas that will spawn innovative and fast growing companies to form the nexus of the knowledge-based economy. This belief is a source of misconceived policies that offer only ultimate disillusion. It is the totality of the university enterprise that is important, as the only place where that totality of ourselves and our world is brought together, and which makes it the strongest provider of the rational explanation and meaning that societies need. In research, universities create new possibilities; in teaching, they shape new people. Its graduates learn to seek the true meaning of things: to distinguish between the true and the merely seemingly true, to verify for themselves what is stable in that very unstable compound that often passes for knowledge. It is the complex, interacting whole of the university that is the source of the separate economic, social, cultural and utilitarian benefits valued by society. It needs to be understood, valued and managed as a whole. These perceptions are a direct challenge to not only to governments but to university administrators who have been either cowed or seduced into the slipshod thinking that is leading to demands that universities cannot satisfy, whilst obscuring their most important contributions. The challenge to both is to permit autonomy without oppressive accountability, and to give staff and students the freedom to think, speculate and research. These are the very conditions of the personal and collective creativity that are the sources of a university’s deepest benefits to its society.     

含剪切自由度的厚薄通用三角形层合板单元

基于一阶剪切变形理论（FSDT）,构造了一种新型的消除剪切闭锁的三角形层合板单元,简记为CDST-S6单元。该单元剪应变场及单元转角场由结点包含有两个剪切自由度的DST-S6单元理论确定,不需要借助减缩积分、假设应力或应变等辅助数学手段,也不会产生对稳定性带来影响的附加零能模式,较好地解决了厚薄板单元的剪切闭锁难题,且其公式推导过程和最终的表达式比目前能考虑剪切变形的绝大多数层合板单元更为简单,可方便地进行有限元数值求解分析。数值算例表明,CDST-S6单元有较高的精度和收敛性,是一种厚薄通用的优质层合板单元。     

新闻自由的宪政渊源分析

新闻自由通常包括创办媒介的自由、报道消息的自由、发表意见的自由和批评监督的自由。新闻自由是言论自由在新闻传播领域的体现,是传统的言论自由、出版自由的发展。     

中西方大学发展的历史比较

大学作为一个绵延数千年的组织机构,在其历史变迁过程中,具有鲜明的文化特征和民族性格。中西方大学发展的历史对此作了充分的注解,并昭示着现代大学发展的基本走向。多样性、国际化、实践性、独立性是现代大学所应具有的特征,而学术自由则构成了现代大学的真谛,是现代大学得以存身立命的根本。     

从图书馆学角度看知识自由

介绍了知识自由的概念和类型,论述了知识自由的原则。     

飞机六自由度模型及仿真研究

以国产某型号飞机为背景提高出六自由度飞机对象建模的一般方法和原则。此建模方法直接根据牛顿第二定律推导出全量非线性方程,没有对刚体运动模型和气动数据做线化处理,考虑了飞机纵横向之间的耦合作用和决定飞机性能的绝大多数因素,因此该模型更精确、更全面地反映了飞机的实际运行特性,并具有具较强的通用性。     

复合自由度波导抑振器的振动声辐射模态

针对附连在无限大障板上的复合自由度波导抑振器(Combined DOF Waveguide Suppressor),用等效的Timoshenko梁理论描述了它的自由振动并确定了该问题的精确解.基于声辐射模态理论研究了波导抑振器声能量辐射和声场中声能量传递的性质;给出了用声强形式表示的声能量辐射模式和声能量传递模式.结果表明,表面声强和空间声强可以分成两部分,一部分将辐射的能量传递到远场;另一部分表现为抑振器本身与外部流场之间能量的交换.
