Movement patterns of Blanding's turtles (Emydoidea blandingii) in the suburban landscape of eastern Massachusetts

We studied Blanding's turtle Emydoideablandingii home range and seasonal movement patterns at 10 sites in suburban eastern Massachusetts during 2001 and 2002. Radio telemetry was used to track 51 turtles (31 females and 20 males) and home range was estimated during 4 seasonal activity periods usingthe 95% fixed kernel estimator. Sex, year, and site were not found to affect home range size due to the large amount of variationbetween and within individuals. There were significant differences in home range length between activity periods, with longest movementsoccurring during the period of 15 April to 31 May as animals moved to ephemeral wetlands. Mean annual home range size for Blanding's turtles was 22 ha, and mean home range length was 856 m. Animals frequently had annual home ranges that overlapped little from year to year, indicating that our calculations greatly underestimate the lifetime home range of an individual. Due to the large area needs of Blanding's turtles, and the diversified ownership of lands in eastern Massachusetts, numerous stakeholders will need to be involved to effectively protect viable populations for the foreseeable future.     

司法权对行政权监督的多重视界

用司法权来监督行政权是现代各国建设法治国家的成功经验。司法权对行政权监督的能力取决于行政诉讼法律制度的建构,在一般性的理解中容易把法院受案范围的大小作为衡量司法权对行政权监督能力的唯一标准。而事实上,行政诉讼中对原告资格的确定,司法审查的强度和标准以及诉的形式和种类等也是考查司法权对行政权监督能力所不能忽视和缺少的视界。

公共财政理念下的预算范围调控之法律进路

预算范围的重新界定在中国预算法修改中居于极其重要的地位。文章所指的预算范围,即预算法界定下的收支类型。在公共财政理念下,预算法禀赋中的民主性原则、完整性原则要求预算范围被重新丈量;立法理论中的法律实施效果判定也对预算范围的界定提出了新的要求。文章通过对现有法律规范及实践的梳理,指出虽然现有法律对预算范围做出了兜底性规定,但因缺乏法律解释使实践操作乏力,而行政法规对于预算范围循序渐进的界定,为其上升为法律提供了理论资源和制度创新的双重支撑;同时,被囊括进入预算范围的部分收支由于其运行中受到体制性因素影响而难以真正实现预算法的目标,故对其界定也需要重新考量。因此,对预算范围的法律设计需要秉承理论,接壤实践,真正实现预算法欲达到的目标。     

上证指数波动率和收益率长期依赖关系的实证研究

运用经典的和修正过的重标极差方法研究了在1999到2009上证指数中的波动率和收益率的长期依赖关系。运用具有预白（pre-whitening）和后黑（postblackening）的Moving block bootstrap方法为假设检验构建置信区间。结果显示上证指数的收益率没有显著的长期相关。但是,波动率具有显著的长期相关。关于收益率的研究和之前一些研究提出的中国股票市场具有可持续性的结论相抵触。并且,之前这方面的研究大多数没有运用置信区间或只是基于标准正态分布的置信区间。因此,这些研究的结果需要从新检验和从新进行解释。

3D object recognition: Representation and matching

Three-dimensional object recognition entails a number of fundamental problems in computer vision: representation of a 3D object, identification of the object from its image, estimation of its position and orientation, and registration of multiple views of the object for automatic model construction. This paper surveys three of those topics, namely representation, matching, and pose estimation. It also presents an overview of the free-form surface matching problem, and describes COSMOS, our framework for representing and recognizing free-form objects. The COSMOS system recognizes arbitrarily curved 3D rigid objects from a single view using dense surface data. We present both the theoretical aspects and the experimental results of a prototype recognition system based on COSMOS.
