管制刀具治安管理探讨

近年来,虽然管制刀具的治安管理取得了很大的成绩,但是由于管制刀具本身异常锋利,在社会面上分散广泛．又具有“五个易’’的特点,治安管理形势依然严峻。对管制刀具进行科学有效的治安管理,首先要明确概念、范围和认定标准,系统梳理其管理法律法规,其次应针对当前存在的主要问题,提出相应的对策和建议。     

日本恢复刑事陪审团制度的动因及其合理性

近来,日本政府宣布将恢复和修改陪审法,建立陪审团制度,实现接近市民的司法.人们希望重新采用陪审团制度,以避免或尽量减少法官的错误裁判,并提升公众的司法信赖感.在陪审制度的类型选择上,日本政府面临英美陪审团制度和欧洲大陆混合法庭制度两种选择.在文化上,日本社会的等级制性质,对权威人物的高度信赖,日本人的团体意识及维持和谐的愿望,有利于陪审团制度的有效运行.在社会方面,日本社会的大多数人属于受过良好教育的、同质性的中产阶级,这有助于陪审团制度的功能与目标的实现.在法律上也没有阻止日本重新引进陪审团制度的障碍.因此,日本将会促成更可能是一种以英美模式为基础的陪审团制度.     

Taphonomic Marks on Pig Tissue Due to Cadaveric Coleoptera Activity Under Controlled Conditions

The aim of this work was to study taphonomic marks that cadaveric coleopteran can produce under controlled conditions. To evaluate this, pig trotters were initially exposed to adults of Dermestes maculatus De Geer at 21 ± 5°C and a 12:12‐h day/night cycle. Observations were made and photographs taken every 4–5 days for 9 months. When feeding and reproducing, D. maculatus produced, in both adult and larvae stages, different types of marks such as holes, striations, scratches, and pits in several kinds of tissue such as integumental, connective, and muscular, in both their fresh and dried stages. Bite marks were also evident. The results in this study provide not only taphonomic but also biological and forensic information. This is the first time that this kind of experiment has been performed.     

Ancestry Assessment Using Random Forest Modeling, ,

A skeletal assessment of ancestry relies on morphoscopic traits and skeletal measurements. Using a sample of American Black (n = 38), American White (n = 39), and Southwest Hispanics (n = 72), the present study investigates whether these data provide similar biological information and combines both data types into a single classification using a random forest model (RFM). Our results indicate that both data types provide similar information concerning the relationships among population groups. Also, by combining both in an RFM, the correct allocation of ancestry for an unknown cranium increases. The distribution of cross‐validated grouped cases correctly classified using discriminant analyses and RFMs ranges between 75.4% (discriminant function analysis, morphoscopic data only) and 89.6% (RFM). Unlike the traditional, experience‐based approach using morphoscopic traits, the inclusion of both data types in a single analysis is a quantifiable approach accounting for more variation within and between groups, reducing misclassification rates, and capturing aspects of cranial shape, size, and morphology.     

Occurrence of contamination by controlled substances in Euro banknotes from the Spanish archipelago of the Canary Islands

The social problems of drug abuse are a matter of increasing global problem. Nowadays, international agencies need fresh methods to monitor trends of the use of illicit drugs. In this sense, small amounts of drugs are transferred to banknotes and they could be detected and quantified. An analytical procedure based upon extraction with organic solvent, liquid chromatography separation, and mass spectrometric detection allowed the identification of 21 drugs and metabolites in 120 used Euro banknotes collected in the Canary Islands (Spain). Most of the banknotes analyzed showed detectable drug residues (92.5%). Cocaine was the most frequently detected drug, present in approximately 90% of the samples. In addition, 75%, 35%, and 15% of the banknotes showed residues of amphetamine derivatives, opiates, and benzodiazepines, respectively. An average of three drug residues per banknote was detected. In summary, the presence of drug residues in banknotes could be useful as tracer for drugs prevalence.     

Using automated comparisons to quantify handwriting individuality

The proposition that writing profiles are unique is considered a key premise underlying forensic handwriting comparisons. An empirical study cannot validate this proposition because of the impossibility of observing sample documents written by every individual. The goal of this paper is to illustrate what can be stated about the individuality of writing profiles using a database of handwriting samples and an automated comparison procedure. In this paper, we provide a strategy for bounding the probability of observing two writers with indistinguishable writing profiles (regardless of the comparison methodology used) with a random match probability that can be estimated statistically. We illustrate computation of this bound using a convenience sample of documents and an automated comparison procedure based on Pearson's chi-squared statistic applied to frequency distributions of letter shapes extracted from handwriting samples. We also show how this bound can be used when designing an empirical study of individuality.     

实践中的刑事一审期限:期间耗费与功能探寻——以S省两个基层法院为主要样板

透过审限耗费角度的实证研究可以发现,我国基层法院刑事审判程序具有如下特征:庭前程序的"事务化",庭前程序沦为纯粹的案件管理活动;庭审程序的"速审化",庭审时间耗费少,庭审节奏明快;庭后程序的"中心化"与"间隔化"。传统观点认为,我国刑事审限制度具有人权保障和效率提升功能。通过比较和实证的考察发现,我国"贯通式"审限的真实功能为通过监控法官的审理行为,达到塑造与行政化司法制度结构相契合的审理主体的目的。     

Visualizing Indented Writing on Thermal Paper by the Controlled Application of Heat

Indented writing on thermal paper made with either one, two, or three sheets of paper above the thermal paper has been visualized by the controlled application of heat to the thermal paper at temperatures below the paper's normal color change temperature. Indentations created by applying a variable pressure to a steel letter stamp showed that, with one sheet above the thermal paper, indentations were more visible at lower pressures than with either two or three sheets above. Handwriting from 20 volunteers produced indented writing graded with most of the text clear and easy to read for all samples with one sheet above, half the samples with two sheets above and eight samples with three sheets above. Comparison with ESDA showed that, with three sheets above, there was a statistically significant difference (p < 0.01), with heating producing more samples than ESDA with most of the text clear and easy to read.     

Time Radically Alters Ex Situ Evidentiary Soil 16S Bacterial Profiles Produced Via Next‐Generation Sequencing,,

Previous research has revealed the potential of soil bacterial profiling for forensic purposes; however, investigators have not thoroughly examined fluctuations in microbial profiles from soil aged on evidence. In this research, soils collected from multiple habitats were placed on evidence items and sampled over time, and then bacterial profiles were generated via next‐generation sequencing of the 16S rRNA locus. Bacterial abundance charts and nonmetric multidimensional scaling plots provided visual representation of bacterial profiles temporally, while supervised classification was used to statistically associate evidence to a source. The ex situ evidence soils displayed specific, consistent taxonomic changes as they aged, resulting in their drift in multidimensional space, but never toward a different habitat. Ninety‐five percent of the 364 evidentiary profiles statistically classified to the correct habitat, with misclassification generally stemming from evidence type and increased age. Ultimately, understanding bacterial changes that occur temporally in ex situ soils should enhance their use in forensic investigations.
