The marginalisation of children by the legal process

A major study carried out in the Melbourne Children's Court, Victoria, Australia, during 1993–1995, of the factors that influence magistrates' decision-making in child abuse cases, found that magistrates relied more on their legal training and individual discretion than on information from the child protection service when making these decisions. Magistrates' emphasis on adversarial procedures meant that the need to establish the facts in a case was the court's primary consideration and that children's interests, and welfare concerns about them, were marginalised in the hearing of child abuse matters. The article reports on this aspect of the larger study: how the adversarial process ill serves the rights, and best interests, of children in the hearing of child abuse matters and provides case examples to illustrate this. The information is drawn from the qualitative and quantitative data gathered for the major study; data collected from the observation of court hearings, interviews with magistrates and court record analysis.     

Lyme Disease: A Case Report

Abstract

Using a needs-assessment technique called story-boarding to determine characteristics of health promotion and wellness among university students is discussed. Storyboarding allows students to work together as they generate ideas and eliminates the territorial defensiveness that often occurs when new ideas are suggested. Sixteen graduate students in a health education teaching methods course demonstrated the use of the technique to identify characteristics of wellness for university students. In addition, they identified content areas and outlined key programs, services, personal habits, and skills useful for enhancing university students' wellness.     

钢筋混凝土空心剪力墙的拓扑优化设计

传统现浇钢筋混凝土剪力墙结构具有自重大、刚度大、抗震作用大、延性差以及保温隔热性能低等建筑节能性能差等等诸多的缺点.随着建筑业的迅猛发展,大量的试验研究和有限元计算分析表明：钢筋混凝土空心剪力墙刚度小,延性好,是一种很好的节能性的延性剪力墙结构,更适用于高层建筑.本文主要利用ANSYS的结构拓扑优化模块对钢筋混凝土空心剪力墙的拓扑形状进行结构优化设计,建立以总体积为目标函数,以应力和变形状态变量为约束条件,以空心剪力墙孔洞的直径为优化变量的钢筋混凝土空心剪力墙的优化设计模型,并采用零阶方法进行优化设计和计算.     

An adaptive sampling scheme guided by BART—with an application to predict processor performance

The evaluation of new processor designs is an important issue in electrical and computer engineering. Architects use simulations to evaluate designs and to understand trade‐offs and interactions among design parameters. However, due to the lengthy simulation time and limited resources, it is often practically impossible to simulate a full factorial design space. Effective sampling methods and predictive models are required. In this paper, the authors propose an automated performance predictive approach which employs an adaptive sampling scheme that interactively works with the predictive model to select samples for simulation. These samples are then used to build Bayesian additive regression trees, which in turn are used to predict the whole design space. Both real data analysis and simulation studies show that the method is effective in that, though sampling at very few design points, it generates highly accurate predictions on the unsampled points. Furthermore, the proposed model provides quantitative interpretation tools with which investigators can efficiently tune design parameters in order to improve processor performance.

Income Comparison as a Determining Mechanism of Class Identification: A Quantitative and Simulation Study Using Japanese Survey Data

This paper questions whether personal income comparison explains the distributive gap between income and class identification by exploring the following two issues: empirical validity of income comparison as the determinant of class identification, and theoretical validity of income comparison for the distributive gap. For the first issue, we conduct a statistical analysis using data from the Social Stratification and Social Mobility surveys (1975–2005), and the Stratification and Social Psychology-I survey (2010). We find that the criteria for choosing reference groups changed historically from residential proximity to occupational equality. In addition, income comparison with sensitive to lower-income possessors and a distorted perception of income difference significantly affected class identification, except for the year of 1985. The simulation analysis employed to examine the second issue clarified that income comparison with the above-mentioned features yields a less skewed distribution compared to that of class identification. The data also indicates that the empirical conditions of income are satisfied for realization of this result. Thus, we could ascertain empirical and theoretical validity of income comparison as explanation for the distributive gap between income and class identification.     

自然伽马能谱测井谱解析方法研究

自然伽马能谱测井是重要的核测井方法之一，其地面信息处理系统的关键是实测谱解析技术。低分辨率是自然伽马能谱测井仪的固有弱点，且测井过程中信噪比较低，造成测井置信度不高。从自然伽马能谱测井原理出发，通过中海油实验数据处理后获得的放射性核素的标准计数率谱，对自然伽马能谱测井4种传统数据处理方法的优劣进行了对比，初步探讨了将灵敏度高、空间分辨率好的直接解调方法移植到自然伽马能谱测井谱解析中，为自然伽马能谱测井谱解析方法的选择提供了依据。

论作为文学社团的中国左翼作家联盟

历来左联研究的薄弱之处在于 ,将左联只是作为一种流派 ,而且是政治性的流派来对待 ,不注重左联首先是一个社团 ,而且是一个文学社团。左联作为文学社团是一个非常典型的研究对象。鲁迅等人都是将左联当作一个文学社团加以理解的。左联虽然是在政治力量的作用下组织起来的 ,但它的聚合过程充分体现了左翼文学家的自觉性。左联所有突出的创作倾向 ,如革命的罗曼蒂克 ,都是左联社团作用的结果。
