金属目标在聚焦天线焦平面上的散射

研究了目标在聚焦口径天线焦点的散射问题。以一个金属目标和一个理想口径组成的系统为例，阐明了这类散射问题的电磁过程。研究结果表明，选择适当的口径分布，可以大大提高目标回波强度。文中给出大量计算结果，并对不同的口径分布做了比较，得到了若干具有工程意义的重要结论。     

Public Meetings and Risk Amplification: A Longitudinal Study

This article offers longitudinal data tracking people who did and did not attend a series of public meetings in an upstate New York rural community grappling with the expansion of an existing solid waste landfill and remediation of an adjacent inactive hazardous waste site. Before and after the public meetings, mailed questionnaires measured risk perceptions and perceived credibility of risk managers (here, the state government agencies and the responsible industry) conducting the meetings. Respondents at each measurement point included meeting attendees and nonattendees, with some fluctuation over time when attendees at one measurement point were nonattendees at the next and vice versa. The results from the first survey indicate that following the first two public meetings, attendees perceived greater risks from the waste sites than did nonattendees; attendees also perceived the risk managers as less credible. After the third public meeting, the results showed that attendees' risk perceptions remained steady; however, perceptions of government agency credibility significantly decreased. After the fourth public meeting, the survey found that attendees' risk perceptions were again not significantly different, whereas perceptions of government agency credibility increased significantly. The industry's credibility also increased, though only among attendees who had attended the most recent public meeting, not among attendees who had attended both the third and fourth public meetings. For nonattendees, risk perceptions and credibility ratings did not change. The discussion examines how distinctive characteristics of communication at each public meeting may have resulted in different effects and proposes hypotheses for future research.     

The practice of deliberative policy analysis in the context of political and cultural challenges: lessons from Thailand

ABSTRACT

This article draws upon insight from a study of those involved in introducing deliberative policy analysis in Thailand at the city scale and presents lessons for both policy practitioners and scholars. The design of each deliberative forum differed, depending on lessons learned from previous forums and the consensus that emerged as a result of deliberation amongst forum facilitators. The underlying principle of this kind of deliberative design is to make deliberative processes authentic, by avoiding coercion, inclusive, by engaging stakeholders who bring forth different ideas, and impactful. To make these forums more exciting, deliberative practices are often linked to other attractive discourses, such as those surrounding smart cities, creative spaces and inclusive development. The case of Thailand sheds light on emerging challenges involved in the practice of deliberative policy analysis in the context of both national political regimes that are not democracies and those in the East.     

孔子人论的再解读

孔子的人论是儒家人论的根基。孔子提出:"仁者,人也。"确定了儒家人论与其所开创的"仁"学的密不可分的关系。本文尝试从"仁"得以产生的两大基石、"仁"的人性内涵、孔子的做人之道及成人之教等方面论述孔子人论的主要内容,并归纳出其人论的重要历史意义。     

浅析货币政策时滞问题兼论我国货币政策有效性

文章首先分析了影响货币政策时滞的因素 ,进而展开了对我国货币政策有效性的讨论。重点对我国货币政策传导机制及其制约因素进行了分析 ,最后提出了提高我国货币政策有效性的几点政策建议     

大学英语分级教学的探索与尝试

进行大学英语分级教学的目的是解决学生在英语学习过程中客观存在的个性差异问题。按层次实施教学,适应大学生个体发展的实际需要,更好地体现因材施教的原则。辽宁医学院的大学英语分级教学目前仍处于尝试阶段,学生学习英语的许多实际问题尚未解决,教师的教学方法和手段还需要进一步改进和完善。     

行政诉讼重作判决的比较及其启示

正确、有效地适用重作判决有利于实现撤销判决之实效,维护客观法秩序。为了更好地发挥行政诉讼重作判决的制度功能,应当将之与我国类似判决形式进行比较,主要是撤销判决与履行判决。同时要将重作判决与英国、奥地利的类似判决形式和法国、德国、日本的撤销判决效力制度进行比较。这些比较对我国行政诉讼重作判决的适用具有重要启示。     

无限长理想导体圆柱对电磁导弹的散射

最近的研究表明,当一个能量按r~(-(?))衰减的电磁导弹投射到无限长平板后,其散射场能量仍按r~(-(?))衰减。电磁导弹在其它目标上的散射特性是一个尚待研究的课题。本文讨论能量按r~_(-(?))衰减的电磁导弹在理想金属圆柱上的散射特性。研究表明,电磁导弹散射场的能量衰减规律正比于r_(-(1+(?)))。这说明在入射场为电磁导弹的情形下,金属圆柱体的散射场能量衰减比平板要快,但仍比常规二维散射场的能量衰减规律r~(-2)要慢。     

企业文化与企业持续成长:基于传导机制的研究

企业文化是影响企业持续成长的重要变量之一。企业文化从内核、制度与行为、外围等三个层面对企业持续成长产生传导作用,并遵循着“理念——制度——行为——习惯——效率——价值——成长”的企业文化传导机制。     

论我国货币政策传导机制中的障碍

通过对近年来我国出现的通货紧缩现象的分析 ,可以看到中央银行所采取的稳健的货币政策的内容及其执行状况。经济的不景气不是由于货币供应量不足而是在于货币政策的传导机制的不畅。我们应找出传导机制不畅的原因 ,并提出相应的对策
