未成年犯社区矫正实施效果评估及其优化

在行刑社会化、轻缓化、人性化的国际视野下,对未成年犯实施社区矫正不仅可以避免监狱矫正的"交叉感染"与"标签效应",还可以降低行刑成本、减轻监狱人满为患的压力,同时,也适应了未成年犯身心特征的需要。实施未成年犯社区矫正,应加强社区矫正宣传与普及工作,创设适合未成年犯特点的矫正项目,建立专门的社区矫正机构和具有可操作性的调查评估机制。     

整体波场延拓法基准面校正与常规方法对比

消除近地表对地震波场所造成的影响，常规的解决方法是静校正和波动方程基准面校正。当勘探区域近地表出现较大的地形起伏或速度横向变化时，波动方程基准面校正则成为唯一有效的选择。传统波动方程基准面校正在实现过程中需要在双域对炮点、检波点分别进行延拓成像。为此，作者曾提出一种新的近地表问题解决方法——整体波场延拓法基准面校正(WEDD)。本文对WEDD方法和常规基准面校正方法在理论上进行了对比分析，并通过数值模拟讨论了各基准面校正方法的优缺点和适用范围。     

Sir Godfrey Thomson: a statistical pioneer

Summary.  Godfrey Thomson (1881–1955) was a leading figure in intelligence testing who made his name in that field first at Armstrong College, Newcastle, and then at the University of Edinburgh. In the course of his practical work he identified many theoretical problems which were essentially statistical in character. In particular, he used maximum likelihood estimation as early as 1919 and his statistical work largely set the course of modern factor analysis and related techniques. His statistical abilities were recognized, at different stages of his career, by both Karl Pearson and Sir Ronald Fisher. His key insight was to recognize the importance of Fisherian inference for the future of that subject.     

对于EFL教师批改学生书面作业的探讨

本篇论文认为虽然有研究表明老师批改学生作业中的语言错误并不能使学生的写作得以显著提高,但是教师批改学生书面作业这个环节不应取消,教师应该使学生参与对于错误的分析和认识过程,老师还应该遵循学生的认知发展规律,在各个学习阶段对于不同种类的错误的修改有所侧重.文章还指出通过调查研究了解学生是十分有益于教学的.     

A qualitative analysis of African American fathers’ struggle with reentry,recidivism, and reunification after participation in re-entry programs

The experiences of African American fathers with reentry, recidivism, and reunification after a period of incarceration and after participation in a re-entry program. Results of the thematic analysis yielded the following major themes: unaddressed childhood trauma, self-identification, reentry; self-esteem and self-worth; reentry; family reunification after incarceration; and recidivism. Unaddressed childhood trauma and post-release stress emerged as the major barriers to successful transition from incarceration. Implications for social work policy, research, practice, and education are provided.     

青少年犯罪社区矫正的社会工作方法探讨

社区矫正是一种与监禁矫正相对的行刑方式,当前青少年犯罪社区矫正日益引起社会各界的广泛关注。自2003年社区矫正试点工作在北京、上海、天津等6省市展开以来,许多专家学者都在探索社区矫正的理论,但尚没有形成适用的方法体系。本文在社区矫正实践经验的基础上,就社会工作方法介入青少年犯罪社区矫正的意义、程序、原则等做积极的探讨。     

SOME RESAMPLING PROCEDURES UNDER SYMMETRY

This paper investigates the properties of bootstrap and related methods assuming that the underlying distribution is symmetric but otherwise unknown. In particular it studies the percentile-t, nonparametric tilting and empirical likelihood and finds that the performance of percentile-t and non-parametric tilting methods can be improved by incorporating the symmetry into the resampling procedure. However, for symmetric empirical likelihood, the Bartlett correctability no longer holds, although use of bootstrap calibration restores the good coverage properties typically associated with Bartlett correction. This surprising result shows that Bartlett correctability is a very delicate property.     

Prison Parenting Programs

Abstract

Estimates indicate that parents make up a large segment of the prison population in the United States. Parental incarceration affects the whole family. For children of incarcerated parents, separation is painful and can be detrimental to their development. Effective parenting programs in prisons can be beneficial to the incarcerated parents, their children, and society. This study surveyed 745 state prisons to gather data on their parent populations and their prison parenting programs. Findings indicate significant differences by gender of prisons and program structures.     

Second‐order Accurate Confidence Regions Based on Members of the Generalized Power Divergence Family

Recently, a technique based on pseudo‐observations has been proposed to tackle the so‐called convex hull problem for the empirical likelihood statistic. The resulting adjusted empirical likelihood also achieves the high‐order precision of the Bartlett correction. Nevertheless, the technique induces an upper bound on the resulting statistic that may lead, in certain circumstances, to worthless confidence regions equal to the whole parameter space. In this paper, we show that suitable pseudo‐observations can be deployed to make each element of the generalized power divergence family Bartlett‐correctable and released from the convex hull problem. Our approach is conceived to achieve this goal by means of two distinct sets of pseudo‐observations with different tasks. An important effect of our formulation is to provide a solution that permits to overcome the problem of the upper bound. The proposal, which effectiveness is confirmed by simulation results, gives back attractiveness to a broad class of statistics that potentially contains good alternatives to the empirical likelihood.     

Pairwise testing of group mean vectors in MANOVA with small samples

Several, multivariate, pairwise, multiple comparison procedures are proposed as follow-ups for a significant multivariate analysis of variance. The Peritz procedure is generalized from univariate to several multivariate applications. Procedures are evaluated using overall power, any-pair power and all-pairs power applied to mean vectors with common sample sizes of 4, 5, and 9. Monte Carlo simulation demonstrated greater power than previously proposed univariate procedures in many conditions especially for all-pairs power. The multivariate Peritz procedure based on the Lawley–Hotelling trace was found to be most powerful in many conditions.
