Bone age assessment: the applicability of the Greulich-Pyle method in eastern Turkish children

The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.     

德日犯罪论的中国命运考量

德日犯罪论第一次进入我国的时候,由于种种原因,并未引起任何反响。再次面对德日犯罪论,刑法学界已经由赞叹走向对该理论的反思。这一反思主要从两个向度上展开：理论自身和方法论。德日犯罪论所具有的外在不稳定性,表明该理论还在发展,其内在的缺陷,显示出该理论仍需完善。而仅仅运用哲学方法对它进行研究也存在一定的问题。德日犯罪论的中国命运不容乐观。     

Dating of Inkpad Seals Using the Extraction Rate Method: Preliminary Findings

Inkpad seals are often placed on important documents, and determining the date when a seal was affixed can be important to assess the authenticity of a document. In this study, three different brands of inkpads and four different types of paper were used to make diachronic samples of the seals. A double‐solvent extraction method was employed to date the inkpad seals by comparing extraction rates with inks of known age. Cyclohexane was selected as a weak solvent, and chlorobenzene was selected as a strong solvent. After testing, curves were created to show the relationship between the extraction percentage of ink and the date of the seals. The experimental results showed that the extraction rate method was applicable for the relative dating of inkpad seals in some cases where the seal was placed on the document within 6 months.     

紫外分光光度法和二阶导数光谱法测定水样中的敌草快

目的建立测定水样中的敌草快的分析方法。方法采用紫外分光光度法和二阶导数光谱法测定水样中的敌草快。结果紫外分光光度法直接测定水样中的敌草快,在0.1~50μg/mL范围内线性关系良好,日内,日间精密度均小于2.6%。二阶导数光谱法在0.1~10μg/mL线性关系良好,日内、日间精密度均小于1.29%。结论该两种方法快速、简单、灵敏,适用于环境监测工作。     

为什么我们没有“新闻法”———反思我国新闻传播立法研究

我国改革开放以来的新闻立法历经30多年至今未果,无论法治社会的内在要求还是传媒领域的现实发展,都表明了迫切的新闻立法诉求。在“新闻法”尚不能出台的众多复杂原因中,学术研究的偏颇却总是被忽略,研究方法的迷失带来学理探讨的浅尝辄止,宏观研究的乏善可陈,以及学科之间的壁垒隔膜。其背后透露出不容回避的学术勇气的不足和技术细节研究的缺乏。基于新闻传播法学理论建设的推进和现实新闻传播立法的需求,应首先在思想和理论上明确：新闻自由是谁的自由,谁可以办报,如何协调采访报道和国家公权力的关系等问题,同时必须关注新闻传播立法技术的研究,如舆论监督的规范体系,为新闻来源保密的规则归属等细节问题。     

刑法解释方法位阶性的质疑

文义解释有诸多局限,需要其他解释方法来印证和检验,因此其并不具有优位性。客观目的解释的功能具有多面性,其仅在目的性缩限时具有绝对优先性,因此不能一概认为其有决定性;主观目的解释仅在提供不处罚的立法资料时具有特殊价值。在刑法解释的商谈、试错过程中,方法的采用有"各取所需"的特点,采用何种解释方法取决于对处罚必要性的判断;解释是一种结果,通常是在结论确定之后再选择解释方法,为法官定罪与否提供"事后注脚";由于司法裁判必须考虑国民的认同感,且要接受后果考察,刑法适用就必须兼顾大量解释方法自身难以涵括的各种复杂因素。因此,如何立足于法条用语的通常含义,将犯罪论体系、规范保护目的、国民的规范认同、处罚必要性等内容一并考虑,并且坚持实践理性,选择对个案最为合适的解释方法,将实质解释的结论限定在特定时代能够接受的范围内,从而平衡好惩罚犯罪和保障人权的关系,是比刑法解释方法的位阶性更为重要的问题。     

Pubic Symphyseal Age Estimation from Three‐Dimensional Reconstructions of Pelvic CT Scans of Live Individuals

Skeletal age estimation using the pubic symphysis is a reliable and popular practice among forensic anthropologists. In instances in which accessing the skeleton is impossible, such as in the case of living individuals, three‐dimensional (3D) reconstructions of computed tomography (CT) scans can be created and analyzed for aspects of the biological profile. This study examined 3D reconstructions of pelvic CT scans of a sample of 44 live adults to estimate age using the Suchey–Brooks J Hum Evol 1990;5(3):227‐38 method. Images were created using OsiriX software (Pixmeo, Geneva, Switzerland). Estimated age ranges based on the 3D‐CT images captured the true age of the individual at the time of the CT scan 79.5% of the time with good intra‐observer reliability. The features best visualized on the 3D images included the ossific nodule and the pubic symphyseal rim. This study shows that clinical CT scanning parameters are adequate for creating 3D images to be analyzed for age using the pubic symphysis.     

GC Analysis of Black Gel Pen Ink Stored under Different Conditions

In many criminal and civil cases in China, the most commonly questioned documents are those written with gel pen ink. An important task for forensic document examiners is to identify whether two or more ink entries in one or more documents were written with the same ink type. The identification of the age of gel ink entries made poses an important and difficult problem for forensic document examiners. In this paper, the volatile components of gel ink were determined and the gel ink was classified by gas chromatography with a flame ionization detector. Calibration curves were created to express the relationship between the content of volatile gel ink components and the age of gel ink entries stored under natural and UV‐induced aging conditions. The correspondence between the natural and UV‐induced aging conditions was also established. The experimental results showed that GC was useful in the analysis of black gel ink and applicable for determining the relative age of gel ink entries under certain conditions.     

宪法解释方法的两种传统及其启示

宪法解释的重要性已经得到了普遍的认可,而在宪法解释方法的历史发展中,存在着两大分支:德国传统和美国传统,二者分别以文义解释和原旨主义为主导性解释方法。虽然两种传统有着诸多差异,但从20世纪以来却出现了趋同的倾向,以重视社会学解释方法为集中表现。在两种传统的差异与趋同中,中国宪法解释可以受到多方面的启示,包括回归宪法文本、期待个案发轫、扩展主体范围和重视社会效果等。
