A LOG‐MULTIPLICATIVE ASSOCIATION MODEL FOR ALLOCATING HOMICIDES WITH UNKNOWN VICTIM‐OFFENDER RELATIONSHIPS*

This research note critically evaluates conventional methods for allocating homicides with an unknown victim/offender relationship to meaningful categories, and it proposes an alternative approach. We argue that conventional methods are based on a problematic assumption, namely, that the missing data mechanism is “ignorable.” As an alternative to these methods, we propose an imputation algorithm derived from a log‐multiplicative model that does not require this assumption. We apply this technique to estimate levels of homicides disaggregated by victim/offender relationship using the Federal Bureau of Investigation's Supplementary Homicide Report (SHR) data for 1996 and 1997, and we compare the resulting estimates with those obtained from the application of conventional procedures. Our results yield a larger proportion of stranger homicides than are obtained from the conventional methods.

大鼠液压冲击脑损伤TGF-β1及其受体TβR I的表达

目的观察脑损伤后TGF-β1及其受体TβRI蛋白表达及其时序性变化,探讨脑损伤的分子机制及法医学脑损伤时间推断。方法用免疫组织化学方法观察大鼠液压冲击脑损伤后TGF-β1及其受体TβRI蛋白在伤后不同时间(30 min、1 h、3 h、6 h、12 h、1 d、3 d、7 d)的表达情况,以正常大鼠及手术大鼠作为对照。结果 (1)正常及手术对照组大鼠脑组织内有低水平的TGF-β1及TβRI表达;(2)脑损伤后1～3d,大脑皮质和脑干TGF-β1/TβRI蛋白表达逐渐增加,7 d时仍维持在高表达水平;(3)海马冲击后12 h～1 d逐渐增加,3 d时仍处于高表达水平,7 d时已开始下降。结论脑损伤可诱导TGF-β1/TβRI基因在脑内表达,其时序性改变可望用于法医学脑损伤时间推断。     

可持续发展的人口问题与对策研究

人口多、底子薄、人均资源相对不足是我国的基本国情。人口问题是制约可持续发展的首要问题。本文通过大量祥实的数据,从人口数量、人口素质、人口结构三个方面分析了我国人口的基本状况,探讨我国可持续发展面临的人口总量过多、人口素质总体水平不高、劳动力数量供给过剩、人口老龄化加速和流动人口不断增多等问题,并提出了依法抓好人口与计划生育工作、加快教育改革和发展步伐、完善城乡社会保障体系、大力发展第三产业和加强流动人口管理相应的对策建议。
