Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

骨龄自动化评估的研究进展

骨龄是反映人体生长发育的一项重要指标,能够较为客观地反映个体生长发育水平及成熟度。传统的人工骨龄评估通常是将左手腕X线片与参考标准进行比较,从而获得相应的骨龄值,该方法既耗时又存在观察者间的差异。近年来,随着计算机科学的不断发展,促使骨龄评估开始由传统的人工评估向自动化评估转变。虽然骨龄自动化评估的研究已相当多,但大部分仍处于实验阶段。本文综述了近年来国内外学者在骨龄自动化评估方面的相关研究与进展,以期为相关研究人员提供参考与研究思路。     

RACIAL AND ETHNIC DIFFERENCES IN PRETRIAL RELEASE DECISIONS AND OUTCOMES: A COMPARISON OF HISPANIC,BLACK, AND WHITE FELONY ARRESTEES*

The present study uses data on the processing of felony defendants in large urban courts to examine Hispanic, black, and white differences at the pretrial release stage. The major finding is that Hispanic defendants are more likely to be detained than white and black defendants. And, racial/ethnic differences are most pronounced in drug cases. In fact, Hispanic defendants suffer a triple burden at the pretrial release stage as they are the group most likely to be required to pay bail to gain release, the group that receives the highest bail amounts, and the group least able to pay bail. These findings are consistent with a focal concerns perspective of criminal case processing that suggests Hispanics as a newly immigrated group are especially prone to harsher treatment in the criminal case process.

High performance liquid chromatographic determination of alcohols with reference to body distribution of methanol

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.     

契约的正义——读《法律、立法与自由》札记

通过对哈耶克自由主义法律理论的解读,笔者提出了一种理解契约正义的思想理路。即在自由主义的视域中,自由是正义的核心价值,正义实为对人的意志本身的评价,而不能从行为结果衡量,因此,不管缔约人追求的具体目的如何,我们应以缔约人意志的自由状态作为评价契约是否符合正义的基本标准;普遍的契约自由的实现有赖于法律的保障,缔约意志实为其内在动机与外在法律互动的结果,唯有以契约法为核心的私法具有保障契约自由普遍实现的功能品性,因此,所谓契约正义实为缔约人依私法自由缔约的契约本身。     

解读交通事故认定书

交通事故认定书是依法公正处理道路交通事故程序中的重要组成部分,它具有如下几个方面的特征:文书制作的法定性、不可行政诉讼性、制作者不具有直接公诉性及并非不可否定性。只有正确解读交通事故认定书、充分认识交通事故认定书的特性,才能切实维护道路交通事故各方当事人合的法权益不受侵害、切实维护国家法律之尊严。
