对我国刑事责任年龄概念的反思与重构

传统的刑事责任年龄定义存在着概念过窄等诸多缺陷,不但不利于司法实践工作,也不利于我国刑事责任年龄立法的完善。笔者通过刑事责任年龄与刑事责任的内在联系的分析,对我国刑事责任年龄概念进行了重新界定。     

2003年俄罗斯经济预测

自1999年至今,俄罗斯经济已连续4年增长。2003年俄经济将继续增长,但增幅不会太大,GDP增长率可预测为3.5％-4.5％。这样预测的理由是,占主导地位的积极因素将决定会继续增长,依然存在的消极因素将决定增速不会太快。为了使俄经济继续保持稳定增长,俄政府将针对目前存在的问题采取一系列调整措施。

New formulae for estimating age-at-death in the Balkans utilizing Lamendin's dental technique and Bayesian analysis

The present study analyzed apical translucency and periodontal recession on single-rooted teeth in order to generate age-at-death estimations using two inverse calibration methods and one Bayesian method. The three age estimates were compared to highlight inherent problems with the inverse calibration methods. The results showed that the Bayesian analysis reduced severity of several problems associated with adult skeletal age-at-death estimations. The Bayesian estimates produced a lower overall mean error, a higher correlation with actual age, reduced aging bias, reduced age mimicry, and reduced the age ranges associated with the most probable age as compared to the inverse calibration methods for this sample. This research concluded that periodontal recession cannot be used as a univariate age indicator, due to its low correlation with chronological age. Apical translucency yielded a high correlation with chronological age and was concluded to be an important age indicator. The Bayesian approach offered the most appropriate statistical analysis for the estimation of age-at-death with the current sample.     

A new approach to amino acid racemization in enamel: testing of a less destructive sampling methodology

Aspartic acid racemization has been found to be an accurate measure of age at death for recent forensic material. This paper examines the practicality of using acid etching of the tooth surface to extract amino acids from the enamel for racemization analysis. By serial etching of the tooth and contamination of the teeth with bovine serum albumin prior to etching, the ability of etching to remove contamination was assessed. The destructiveness of the method was visualized and quantified using micro-computed tomography (micro-CT). By bleaching the teeth and by deeper etching it was possible to obtain more consistent values. While etching had little effect on the enamel at the macroscale, it did have an impact at the microscale. The quantities of enamel removed varied depending upon the tooth morphology, but were not large. Acid etching of enamel thus appears to be a promising new method for extracting proteins for amino acid racemization age estimation noninvasively.     

Ossification of laryngeal structures as indicators of age

As the role of forensic anthropologists expands to the medical examiner setting, their expertise is being applied beyond the traditional dry skeletal material. In such scenarios radiographic techniques can be applied when maceration is not appropriate. This study explores the use of radiographic analysis of laryngeal structures for age-at-death determination. Isolated human laryngeal structures (n = 104) from individuals between the ages of 15 and 89 were removed at autopsy and radiographically examined. The cricoid and individual regions of the thyroid cartilage were scored according to degree of ossification, and the relationship between age and degree of ossification statistically examined. A previously published study on age-determination from thyroid ossification by Cerny was assessed for accuracy. The results of the study indicate that although a consistent sequence in the ossification of laryngeal structures exists, variations in timing does not permit narrow age range estimates. Consequently the method presented by Cerny is inaccurate and should not be used in the forensic setting.     

年龄推断的研究现状

推断年龄目前主要依据人体骨骼、软组织、细胞和生物大分子,以及组织中各类物质的物理和化学特性等随年龄增长的时序性变化。由于生物体各组织器官生长发育的生理性变化及其影响因素极为复杂,不同推断年龄的方法均有其应用价值,但也都存在一定的局限性,在法医学实际检案中如果能综合运用,可提高年龄推断的准确性。本文回顾国内外年龄推断现状,并对各种推断方法进行讨论。     

14岁青少年骨发育的变化趋势

目的描述当前我国14岁青少年手腕骨发育特征,并初步评估14岁的青少年骨发育的变化趋势。方法以湖南娄底地区14岁青少年为对象(男53人,女56人),拍摄左手腕部X线片,参照顾氏图谱法描述各选定观察部位并分析发育特征,将统计结果与顾氏图谱法14岁骨龄标准进行比较分析。结果与顾氏法相比,男生组桡骨远端、第1掌骨近端和近节第4指骨骨骺发育程度较高,而女生组桡骨远端、第2～5掌骨、第1～5近节指骨和第2～5中节指骨骨骺发育程度较高。结论当前我国14岁青少年骨发育存在提前趋势,在女生组尤为显著。14岁是刑事责任年龄点之一,法医推断该年龄时应注意该特征对推断结果的影响。     

小鼠皮肤切创愈合过程中p-JNK变化及其与时间的相关性

目的 探讨小鼠皮肤切创愈合过程中损伤区磷酸化JNK（p-JNK）的变化及不同损伤时间p-JNK的变化规律。方法 应用免疫组织化学和Westernblot方法检测小鼠皮肤切创后各个时间段p-JNK的变化情况。结果 正常组织中有少量p-JNK阳性着色。伤后3～12h损伤区p-JNK阳性着色主要在中性粒细胞,1～5dp-JNK阳性着色主要为单核细胞和成纤维细胞,7～14dp-JNK阳性着色以成纤维细胞为主。阳性细胞率3h～1d逐渐增高,1d达到峰值,3～5d有所下降,7d阳性细胞率达第二峰值。10～14d逐渐降低。Westernblot显示各个时间段均有p-JNK的阳性条带,其中12h和3d为p-JNK含量的2个高峰。结论 小鼠皮肤切创愈合过程中p-JNK在损伤区对诱导中性粒细胞、单核细胞和成纤维细胞的凋亡起非常重要的作用。同时P-JNK的规律性变化可用于损伤时间推断。     

浅析低龄职务犯罪心理及预防

职务犯罪低龄化现象日趋严重，面对这一现象，学者们习惯于从宏观视角分析其原因及预防措施．而对低龄职务犯罪心理甚少关注。通过对低龄职务犯罪的概念、特点、危害以及几种典型心理进行分析，深入探索低龄职务犯罪心理结构中的各具体心理要素，并进一步将整个低龄职务犯罪心理的形成过程动态化，从而对低龄职务犯罪进行心理预防。
