反思与探究:“孙大午案”的剖析及司法理念的重塑

"孙大午案"折射出司法者对非法吸收公众存款罪持宽泛理解的态度,通过本案可看出法体系整体性思考的重要性,以及前置法——刑法阶层性思维的必要性。非法吸收公众存款罪中的"存款"应仅限于"银行信用"范畴,通过引入"既存的实质性联系"标准对"不特定"的内涵进行限定,从而实现前置法与刑法之间的衔接。进一步,刑法具有二次性违法的特征,司法过程切忌价值先行。     

Forensic determination of hair deposition time in crime scenes using electron paramagnetic resonance

Several types of biological samples, including hair strands, are found at crime scenes. Apart from the identification of the value and the contributor of the probative evidence, it is important to prove that the time of shedding of hair belonging to a suspect or victim matches the crime window. To this end, to estimate the ex vivo aging of hair, we evaluated time‐dependent changes in melanin‐derived free radicals in blond, brown, and black hairs by using electron paramagnetic resonance spectroscopy (EPR). Hair strands aged under controlled conditions (humidity 40%, temperature 20–22°C, indirect light, with 12/12 hour of light/darkness cycles) showed a time‐dependent decay of melanin‐derived radicals. The half‐life of eumelanin‐derived radicals in hair under our experimental settings was estimated at 22 ± 2 days whereas that of pheomelanin was about 2 days suggesting better stabilization of unpaired electrons by eumelanin. Taken together, this study provides a reference for future forensic studies on determination of degradation of shed hair in a crime scene by following eumelanin radicals by utilizing the non‐invasive, non‐destructive, and highly specific EPR technique.     

Trajectory Reconstruction Through Analysis of Trace Evidence in Bullet–Intermediate Target Interaction by SEM/EDX

Abstract:  A young male was shot to death by a police officer with a Chinese Type 64 7.62 mm pistol when he was dealing with an aggravated assault arising from a traffic accident. By using scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM/EDX), trace deposits on the discharged bullet and the intermediate target, i.e., a concrete telegraph pole at the scene, were identified to be from each other. The result demonstrated the bullet causing the death ricocheted from the concrete telegraph pole before striking the victim, thus indicating the incident was accidental. The case report illustrates the evidential value of trace materials derived, respectively, from discharged bullets and intermediate targets in bullet–intermediate target interaction for trajectory reconstruction. In addition, it indicates that the SEM/EDX method with its nondestructive nature, compared to other methods, may be more helpful in certain situations in determining the origins of trace evidentially valuable deposits on substrates.     

论我国司法鉴定人资格制度的完善

我国司法鉴定组织体系是在司法实践中形成的部门分设体制,在鉴定机构设置的原则、布局上呈现出多元化特点,存在司法机关内部鉴定机构、具有行政权背景的鉴定机构和面向社会服务的鉴定机构等三种类型的鉴定机构,由此导致对司法鉴定人实行职业资格与执业资格制度管理方面存在不尽完善之处。为确保司法鉴定人具有较高的业务水平、执业能力和规范执业,提高鉴定质量,有必要实行复合制的鉴定准入制度、建立健全鉴定业务的经常性培训交流与考核机制、建立法官对鉴定结论的实体审查制度和建立司法鉴定专家库等。

自然灾害防治中的环境法律问题

频发的自然灾害对各个部门法都提出了诸多急需解决的法律问题，环境法自不例外。自然灾害法和环境法是两个相对独立的法律领域，但两者都涉及到特定社会关系的法律调整，这正是目前在自然灾害防治中所出现的、急需研究和解决的环境法律问题，具体包括：次生环境灾害的防治、紧急行政权力对原法律秩序的改变、不可抗力对法律责任的免除。解决前述问题，需对相关法律和《汶川地震灾后恢复重建条例》进行必要的修改完善。

RISK AND PROTECTIVE FACTORS FOR SECONDARY GIRLS OF INCARCERATED PARENTS

In a review of the literature on child gender and gender‐specific effects for children of incarcerated parents, the present paper examines what we do and do not know about gender‐specific protective and risk factors for children of incarcerated parents. The nuanced effects of parental separation based on child gender are offered, drawn from secondary level girls in an all‐female support group operated at a secondary school in Little Rock, Arkansas for the past six years. Other programs are examined that evidence gender‐specific effects for boys and girls in those programs. A few basic statistical indices suggest that the gender of an adolescent separated from his or her incarcerated parents has differential impacts to be better studied and possibly considered in service programming. The results may enhance the outcomes for the girls, and perhaps the boys.
