古代夯具述论

土木结构是我国古代建筑的主要形式,夯具则是重要的建筑工具,它的改良和发展与生产力水平的提高紧密相关。从考古材料看,夯具主要有石质、木质和铁质三种类型,其形制的演变和功能的改善,不仅反映了人类改造自然能力的提高,也是社会进步的一个重要标志。

法益抽象化、精神化问题的中国型塑

法益具有立法批判、解释机能,能够、应当、且需要存在。当前学界对法益抽象化、精神化之批判存在前提设置不当、循环论证及混淆对法益进行抽象化、精神化理解与刑法是否应保护某些抽象化、精神化法益的关系的问题。唯有完成法益抽象化、精神化问题的理性型塑,才能合理认知法益论,进而实现刑法处罚的正义化。即使刑法不当保护了某些抽象化、精神化法益,也只能证明法益的立法批判机能需要得到进一步发挥。若从外在形式与内在内容这两个层面上理解“抽象”与“具体”之意,则刑法法益的抽象化不止是个例,诸如侮辱罪、诽谤罪等罪名的正当化已然表明某些精神化法益值得刑法保护。     

新诗诗形建设的历史透析及现实反思

相对规范的诗形是诗的重要的文体标志,诗形建设是百年新诗诗体建设的重要内容.新诗的形体建设道路曲折,百年间始终存在着诗形的自律与自由的极端对抗.在现代人的图像思维高度发达的图像时代和新诗的传播手段丰富多彩的网络时代,更应该加强以新诗的形体建设为重心的诗体建设,适度规范诗形.目前新诗界的"诗体重建"运动更要高度重视新诗的"诗形建设".

论中国电视综艺节目中的公共领域概念

针对电视综艺节目公共领域问题的争论,从理论上分析了考察传媒公共领域的伦理维度,阐述了电视综艺节目公共领域的存在形式,进而提出平民大众的变化与成长使电视综艺节目建构公共领域具有了可能性,平民大众追求一种自由和善的生活是电视综艺节目公共领域的内涵,情感共鸣、认同与形塑是其表现形式。     

环状压电超声电机的多频率驱动分析与实验

针对压电超声电机的多频率驱动问题进行研究,设计并制作了利用定子内圆周面驱动的环状压电超声电机,明确了利用行波驱动电机转子的机理。通过有限元计算给出了电机定子所用弯曲模态的振型与位移云图。以计算结果为基础,分析了电机所用的压电陶瓷片的极化分区与定子弯曲模态激发之间的关系,得出了所用的压电陶瓷片能够实现电机多频率转动的结论。完成了所研制的超声电机的多频率驱动实验。实验结果表明,电机能够实现在多频率点的转动。依据本文分析思路,可以对其他结构形式的超声电机的多频率驱动问题进行研究。     

THE RELATIONSHIPS BETWEEN SKEWNESS AND KURTOSIS

Theoretical considerations of kurtosis, whether of partial orderings of distributions with respect to kurtosis or of measures of kurtosis, have tended to focus only on symmetric distributions. With reference to historical points and recent work on skewness and kurtosis, this paper defines anti-skewness and uses it as a tool to discuss the concept of kurtosis in asymmetric univariate distributions. The discussion indicates that while kurtosis is best considered as a property of symmetrised versions of distributions, symmetrisation does not simply remove skewness. Skewness, anti-skewness and kurtosis are all inter-related aspects of shape. The Tukey g and h family and the Johnson Su family are considered as examples.     

Can gender differences in distributional preferences explain gender gaps in competition?

We design a lab experiment to specifically examine whether a preference for favorable inequality and behindness aversion, as well as egalitarian preferences, affect competitive choices differently among males and females. Using data on approximately 2,000 subjects, we find that selection into competitive environments is negatively related to egalitarian preferences, with smaller negative impacts of being egalitarian on females’ choice to compete. Further, behindness aversion and preference for favorable inequality affect willingness to compete in opposite ways. The willingness to compete is negatively affected by behindness aversion, while a preference for favorable inequality positively influences willingness to compete. Interestingly, when we disaggregate behavior along gender lines, we find that compared to behindness averse males, behindness averse females are more likely to enter the competitive environment. In contrast, there is no significant gender difference in the impact of preference for favorable inequality on competition. Our results suggest that the observed gender difference in competitiveness can stem from male-female differences in distributional preferences and selected personality traits developed during one’s lifetime.
