The implementation of the bayesian paradigm

Routine implementation of the Bayesian paradigm requires an efficient approach to the calculation and display of posterior or predictive distributions for given likelihood and prior specifi- cations. In this paper we shall review some of the analytic and numerical approaches currently available, describing in detail a numerical integration strategy based on Gaussian quadrature, and an associated strategy for the reconstruction and display of distributions based on spline techniques.     

光影：建筑艺术的灵魂

首先对建筑设计和建筑美学中光影的特殊性进行了详细的论述,提出设计光的原则就是以光的差别为依据,并把建筑上的用光分为两种:即光塑造形体和光营造气氛。之后分别就历史上成功的建筑实例来阐明建筑上的光塑造形体和光营造气氛用光成功经验。在光塑造形体中,主要研究了建筑的雕塑感的获得,尤其以阳光充沛的地理位置为盛。在光塑造形体中,分为了三种情况研究,古代教堂用光、现代教堂用光和公共建筑或住宅用光。在文章的结尾,指出用光设计的高层次性和生活基础。     

基于光纤光栅传感阵列及双目视觉的内窥镜三维显形系统的研究

内窥镜柔性杆在体内的形状显示是一种新型的技术,在这种技术的帮助下,当病人的结肠处于一种不正确的位置上或者说在进境的过程中内窥镜柔性杆的形状形成了扭曲,而形状扭曲会导致内窥镜检查的不安全性,如果预先知道这种状况的发生,就能给诊断带来安全性。本文主要研究了一种基于光纤光栅传感阵列的内窥镜柔性杆的形状及双目视觉的内窥镜镜手柄部分的姿态检测方法,这两种方法的集成构成了整个内窥镜的显形系统。详细的分析包括基于光纤光栅传感器信息的检测原理以及空间曲线重建算法,内窥镜手柄部分相对于世界坐标系的位姿估计。实验结果证明了提出方法的有效性。比较以前的研究,形状重建的精度已经提高到了4.5mm。通过加入内窥镜手柄的位姿检测,整个三维形状显示子系统变得更加有效和更实用化。     

试论高校学生管理公示制度的背景和意义

管理过程的公正和效率与管理过程信息披露的程度和方式是密切相关的。在高校学生管理工作中以公示制度取代公告制度是一个与社会改革发展同步的制度变迁,是寻求更为积极、互动信息交流的管理改革尝试,其背景和意义是值得探讨的。     

Graphical Display of Means

A graphical procedure for the display of treatment means that enables one to determine the statistical significance of the observed differences is presented. It is shown that the widely used least significant difference and honestly significant difference statistics can be used to construct plots in which any two means whose uncertainty intervals do not overlap are significantly different at the assigned probability level. It is argued that these plots, because of their straightforward decision rules, are more effective than those that show the observed means with standard errors or confidence limits. Several examples of the proposed displays are included to illustrate the procedure.     

On Graphing Paired Data

Techniques for graphing paired data are considered. A conventional method frequently used when reporting scientific results, particularly in medical journals, involves representing pairs of measurements by straight line segments titled at different angles related to the differences between the components of the data pairs. However when the sample size is only moderately large, this type of display can become cluttered and thus uninformative due to overlap. It is suggested that a new graph that combines features of ANOVA plots and multivalued dot charts may provide a more effective visual display of paired data. A designed experiment in data perception using simulated data provides some evidence in favor of this parallel line plot.     

The concept of family: Perspectives of Spanish young people in foster care

This article employs concepts from family sociology to explore how ‘family’ is conceptualised in 14 life narratives of young people in foster care in Spain. The article draws on a multi-method approach with young people who are in long-term non-kinship foster care. Seven girls and seven boys aged 10 to 22 took part in the study. The empirical material reveals an interplay between biological preference and foster family affective practices in young people's narratives, illuminating a struggle to make sense of the concept of family in foster care. Most of the participants understand family as shared affective practices sustained through love, commitment, consistent care and reciprocity rather than blood ties. Some show a preference for biological connectivity, while others describe family as determined by rituals and family displays. The key practice implications highlight the importance helping young people positioning themselves in birth family relationships, and supporting their sense of family belonging.     

双薪家庭的家务性别分工：经济依赖、性别观念或情感表达

基于２０１０年第三期中国妇女地位调查数据的分析显示,城镇家庭的家务劳动分工具有“女性为主,男性为辅”的特征。研究表明,经济依赖关系、工作时间、性别角色观念均显著地影响着两性的家务分工,但其影响机制存在差别。对于男性而言,经济上的独立与成就对于其家务劳动投入的影响最大,其次是工作时间与性别角色观念,这些要素均相对独立地发挥作用,男性家务劳动的承担不存在“性别表演”。对于女性而言,纯粹的经济独立（对配偶收入的依赖程度、本人的绝对收入状况等）并非其家务劳动投入的最好预测,性别角色观念也不独立地对家务劳动参与产生影响。部分女性的家务劳动在经济依赖与性别角色观念交互影响下存在着形态与效应各异的“性别表演”。这一特征揭示了两性在劳动力市场中的经济地位与社会文化期待交互影响的形塑作用。
