论我国农村集体土地征用社会保险补偿机制

伴随着城市化进程的不断加快，大量农村集体土地被征用，被征地农民的基本权益保障问题突出。构建一套行之有效的土地征用社会保险补偿机制，是切实保障被征地农民基本权益的重要手段，也是顺利推进城市化进程的重要工具。     

Metamorphosis in hospitality: A tradition of sexual harassment

This study measures the incidence and tolerance of sexual harassment in hospitality in an effort to understand its causes. It examines the tradition of sexual behaviour in hospitality, exacerbated by hierarchical structures, the nature of hospitality work, the characteristics of typical front line workers, customers’ reduced sense of responsibility, and an emphasis on meeting customers’ needs. Customer contact is shown to be a key predictor of harassment, especially for young European women. The typical profiles of hospitality staff and the nature and traditions of the industry are considered important causes of harassment in hospitality.     

构建征地补偿的正当程序规制

征地公正补偿问题已成为土地征收中的热点和难点。公共选择的经济学实证方法论提供了分析征地补偿不公制度性因素的崭新视角。对征地补偿进行正当程序规制是次优的法治模式选择。

Contesting rural recreation: the battle over access to Windermere

Different forms of recreation are competing increasingly for space to operate, and arbitrating between these competing claims can be fraught with difficulties. This paper examines the recent conflict over attempts to impose a speed limit, and hence prevent power boating and associated activities, on Windermere in the English Lake District. The competing arguments, as presented to a public inquiry, are assessed in the light of the Inspector's verdict on these issues, and the political responses to the verdict. The case is likely to have a much wider significance in terms of land use planning policy in Britain, both in National Parks and rural areas more generally.     

微波带状线低通滤波器的设计制作与性能改善

讨论了带状线低通滤波器因实际制作的导带宽度发生变化引起滤波器性能下降时，如何改善滤波器性能的方法。我们采用惠普公司ＥＥＳＯＦ软件，对滤波器的结构和电气参数和分别作了灵敏度分析，以此为改善滤波器性能的依据。经实验对比，改进后的滤波器性能有了明显改善，且性能稳定。
