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。     

民事责任的两种规范模式

民事权利义务规范的设定有行为本位和资源本位两种模式,民事责任规范作为民事规范的一种也不例外。传统的学说将民事责任界定为义务的违反显然是行为本位视角的产物,实际上民事责任的产生与当事人的义务违反没有必然联系。民事责任是为保护民事权利或者法益,基于特定的法律事实而对一定的民事主体产生的不利后果。根据民事规范的设定模式,可以把民事责任规范设定模式分为“义务(行为)——责任”模式和“权利(资源)——责任”模式两种,其中前者是行为本位视角的产物,后者是资源本位视角的产物。     

学校需要更多的情感教育--对马加爵事件的教育学反思

目前学校教育对情感教育的相对忽视是导致马加爵事件发生的重要原因,应该充分认识情感教育的必要性和重要性,加强情感教育内容、方法等的系统研究,在各级各类学校中实施情感教育并确保取得实效.     

The individuality of fibres used to provide forensic evidence--not all blue polyesters are the same.

Fibres used in forensic casework suffer from a disadvantage common to other forms of trace evidence--it is not possible to state with absolute certainty that they originate from a specific source. Target fibre studies, population studies and research on 'blocks of colour' have effectively demonstrated the polymorphism of textile fibres (particularly man-made ones) and have shown that when a fibre is believed to have a specific putative source, the chance that it has originated from a different source purely by coincidence is extremely remote. A study by Houck MM (Houck MM, Inter-comparison of unrelated fibre evidence. Forensic Science International 2003; 135: 146-149) has shown that no coincidental matching fibres were recovered from items of clothing examined in 20 unrelated crimes. The study involved over two million comparisons. This work goes a step further, and using the example of blue polyester fibres shows that even within a very narrow segment of the whole general fibre population, many examples of a specific colour/type of man-made fibre taken from random sources can be compared and the chance of any two being the same is very low. These studies should help to show the specificity and value of transferred fibres in providing forensic evidence.

女性的身份认同与自然科学的基础--以物理学教学为例

传统观念认为女性不适合、也不善于学习自然科学;但是,一些女性主义研究者认为,正是传统的性别观念导致了女性与男性对自己的性别身份认同的偏差,而女性对自己的身份认同与学习自然科学所要求的身份的差距,成为女性学习自然科学的障碍之一.在国外相关研究的基础上,以物理学教学为例分析传统的与物理学相关的身份认同对女性学习物理学产生的消极影响,提出改变这种身份认同的方法,由此,在性别的视角下对自然科学的基础与性别之间的关系做出一个不同于传统观念的新的解释.
