块运动估计的研究进展

运动估计是根据视频序列中时间上相关的信息估计场景或目标的2维运动向量场的过程。运动估计在超分辨率图像复原中的作用是把所有低分辨率观测帧的像素映射到参考帧的相应位置。精确的运动估计是超分辨率图像复原的关键。基于块的模型是超分辨率图像复原中常用的运动估计方法。介绍了块运动估计的概念,概述了4类快速块运动估计的方法,详细描述了第1类方法中几种主要算法的搜索过程,并将多种快速块匹配算法进行了总结比较。

The Adoptee's Journey

The subject of adoption has often been mired in wishful thinking and denial. Because of the secrecy in the system, adopted children have been forced to repress their need to know about their origins; many feel invisible because an essential part of them is unacknowledged by their adoptive parents and society. The purpose of this article is to help mental health and legal professionals, as well as those in the extended community, to see what is specific about the formation of the adoptee's inner world. It introduces the concept of cumulative adoption trauma and discusses the adoptee's need to dissociate feelings of loss, grief, and anger. The struggle to form a coherent sense of self may eventually lead to the adoptee's need to search out the birth parents in order to integrate the past and the present and move on into the future.

Adapting the optimal job search model for active labour market policy

Summary.  The structural theoretical framework for the analysis of duration of unemployment has been the optimal job search model. Recent advances in computational techniques in Bayesian inference now facilitate the analysis of incomplete data sets and the recovery of structural model parameters. The paper uses these methods on a UK data set of the long-term unemployed to illustrate how the optimal job search model can be adapted to model the effects of an active labour market policy. Without such an adaptation our conclusion is that the simple optimal job search model may not fit empirical unemployment data and could thus lead to a misspecified econometric model and incorrect parameter estimates.     

Robust methods for the analysis of spatially autocorrelated data

In this paper we propose a new robust technique for the analysis of spatial data through simultaneous autoregressive (SAR) models, which extends the Forward Search approach of Cerioli and Riani (1999) and Atkinson and Riani (2000). Our algorithm starts from a subset of outlier-free observations and then selects additional observations according to their degree of agreement with the postulated model. A number of useful diagnostics which are monitored along the search help to identify masked spatial outliers and high leverage sites. In contrast to other robust techniques, our method is particularly suited for the analysis of complex multidimensional systems since each step is performed through statistically and computationally efficient procedures, such as maximum likelihood. The main contribution of this paper is the development of joint robust estimation of both trend and autocorrelation parameters in spatial linear models. For this purpose we suggest a novel definition of the elemental sets of the Forward Search, which relies on blocks of contiguous spatial locations.     

《萤窗异草》中的人仙恋及其文化心理原型

尝试从人仙恋作为白日梦的角度入手 ,分析这类恋情乃现实生活中 ,人类因精神、物质上的种种欠缺所作的幻想 ;在托幻中寻求补偿和满足 ,以平衡失重的心理。战乱相寻、尘世纷扰 ,因而有仙乡的追求。人类对年老、死亡的焦虑及畏惧 ,亦凝结为对不死的企盼。在仙恋、仙婚中 ,更有一类包含启悟元素之作。在这类篇章中 ,主人公因仙侣的引导 ,去除品格上某些劣根或习性 ,得仙人“度脱”成仙。除了精神上的启悟外 ,人仙恋亦能满足主人公在物质生活上的匮乏     

中韩诗文中的三笑题咏

据旧题晋无名氏所撰《莲社高贤传》载,慧远雅重陶渊明与陆修静,打破“送客不过虎溪”的惯例,“语道契合,不觉过溪,因相与大笑”。尽管不乏学者对这类逸闻的真实性表示怀疑,但唐宋以来“虎溪三笑”不时出现在艺术家笔下,成为诗文或绘画中的有趣题材。这一题材也受到海东艺术家与文学家的关注,不仅引来丹青摹绘,还出现诗文题咏。他们或向往“一笑乾坤窄”的“千古风流”,或追究三贤是否“同调”,或解析慧远“破戒”之因,诸多题旨既可形成与中国相关诗文的参照,也可反映域外文学家对慧远等三贤的评价意见。     

民族地区基层政府领导力：问题透视与路径选择

民族地区基层政府领导力是维护社会稳定的关键。社会转型时期各类矛盾凸显,基层政府领导力也受到前所未有的挑战,尤其是信任基础薄弱、公共政策失衡、危机意识不强、基层组织弱化等问题严重影响民族地区基层政府的公共治理能力。当前应按照和谐社会的本质要求切实提升基层政府领导力,重点是重塑政府形象、强化服务职能、完善决策机制、提高社会...
