司法职业资格考试制度及其相关问题研究

我国司法职业资格考试制度的确立对于提升我国司法职业群体的职业素质和推动司法职业群体的职业化进程具有重要意义.但从司法职业资格考试制度和司法制度以及高等法学教育的关系的维度分析,我国司法职业资格考试的制度设计存在明显缺陷.因此,借鉴国外有关国家的有益经验,进一步完善我国司法职业资格考试制度是十分必要的.

Detection of Inflicted Bruises by Alternate Light: Results of a Randomized Controlled Trial

Bruises are often difficult to detect on victims of violence, potentially impacting investigation and prosecution. The purpose of our randomized controlled trial was to measure the effectiveness of an alternate light source (ALS) within visible and long ultraviolet spectrums at improving bruise detection compared to white light over time. We also examined the effects of skin color, age, gender, localized fat, and injury mechanism on bruise detection. Participants included 157 healthy adults with balanced sampling across six skin color categories. Bruises were created under the controlled application of a paintball pellet and dropped weight to one upper and lower arm, respectively. Using a crossover design, both bruises were examined 21 times over 4 weeks. Ten different wavelength (350–535 nm) and filter (yellow, orange, red) combinations were used. Multilevel models were used to analyze 2903 examinations on both upper and lower arms. Results in multivariable models showed after controlling for other covariates 415 and 450 nm using a yellow filter had greater odds of detecting evidence of bruising than white light (Upper Arm: 415 nm: OR = 5.34, 95% CI: 4.35–6.56; 450 nm: OR = 4.08, 95% CI: 3.36–4.96). Under either light source, being female and having more localized fat had increased odds of detecting bruises created by the dropped weight (female: OR = 2.96, 95% CI: 2.37–3.70; fat: OR = 1.21, 95% CI: 1.09–1.34). Our results support ALS as an appropriate tool to enhance concurrent physical assessment of bruises in the presence of known history of injury. Future development and evaluation of clinical practice guidelines for ALS application are needed.     

Determining Shoe Length from Partial Shoeprints

The length of a shoe has significant value in reflecting characteristics of the owner, and thereby, it can help in tracking suspects in criminal cases. However, the shoeprints left at a crime scene are often incomplete, resulting in difficulties in assessing shoe length. To find a way to estimate the shoe length from a partial shoeprint, 109 shoes with different sizes and general patterns were collected, and their prints were lifted using magnetic powder. Four feature points were defined on a shoeprint, and the longest distance between the feature points was defined as shoe length. Using linear, quadratic, and cubic regression analyses, a total of 15 equations were obtained between the shoe length and the other distances between the feature points. Out of these, the five most accurate equations were selected as the optimal equation. The verified test, including another 18 pairs of shoes, showed an average error of equations between 0.591 cm and 0.732 cm. The equations were also applied in two practical cases, resulting in good accuracy. The study demonstrates that shoe length could be determined from partial shoeprints through the proven equations.

The relationship between gunshot-residue particle size and Boltzmann distribution

Gunshot-residue(GSR)particles usually form spherical structures,have special dimensions,and a composition that consists of burned and partially unburned matter with a 0.5–50-mm diameter(sometimes larger).The GSR particle-size distributions have been argued to be caused by the effects of equilibrium-surface distributions during formation and have not yet been correlated with a theoretical analysis or probability distribution.This study proposes a model to explain the GSR particle-size distribution quantitatively.Based on the data,and,as predicted by our model,the number of GSR particles decreases proportionally to the inverse square of the GSR particle size as the particle size increases.This result occurs because of the abundance of microstructures that are encountered in the GSR particles.     

What can glove impression evidence reveal about assailants? A pilot study

Impressions and marks are expected components of any crime scene.There is nothing more disappointing for fingerprint experts than finding glove marks at a crime scene.The forensic expert’s primary task in such cases is to compare the characteristic features of glove impressions with the characteristics of a suspect.The aim of the present study was to determine whether additional information could be obtained from glove prints.Specifically,whether they could be used to help to predict the sex and stature of a suspect was investigated,as was the potential for ascertaining additional information in cases where such prints were recovered from diverse objects with different diameters.Male and female participants wore latex gloves,and after ink was applied to the gloves they grasped objects of different diameters(2,4,6 and 8 cm).Impressions of gloved flat hands were also obtained.Phalangeal and finger lengths were measured digitally via software.Sex and stature were successfully estimated based on impressions derived from gloved flat hands and from prints on various grasped objects.A regression equation was developed for stature prediction,and a discriminant equation was developed for sex prediction.     

司法精神病鉴定基本问题研究

近年来我国刑事司法实践中曝光的若干典型个案凸显精神病鉴定的混乱状况。实证调研发现,精神病鉴定自身的特征——对象的复杂性、过程的回溯性、知识背景的跨学科性、手段的有限性与结论的主观性,影响到其客观性与可信度。目前精神病鉴定存在的问题主要包括启动难、鉴定过程中医学与法学学科错位、诉讼权利保障机制欠缺、强制医疗制度带有行政化特征以及鉴定体制改革引发的问题。应当在坚持职权主义启动模式的基础上,对部分死刑案件增设强制启动机制,增设申请启动鉴定的上诉途径,细化启动考量标准;司法精神病专家与法律职业群体之间应当重新分工;应当增设被鉴定人由于鉴定导致人身自由被剥夺的法定强制措施以及在专家辅助人的帮助下对鉴定意见的质证权;强制医疗程序应当进行司法化改造并通过社会化途径加强执行能力;在鉴定管理体制上,应当取消现有鉴定主体限于医院的规定,恢复等级化的体系设置并建立鉴定人准入与培养机制。
