Effects of Cremation on Fetal Bones

The charring process is a weak point of anthropological analysis as it changes bone morphology and reduces information obtainable, specially in fetuses. This experiment aims at verifying the conservation of fetal bones after cremation. A total of 3138 fetuses of unknown sex and age were used, deriving from legal and therapeutic abortions from different hospitals of Milan. Cremations took place in modern crematoria. Nine cremation events were analyzed, each ranging from 57 to 915 simultaneously cremated fetuses. During the cremations, 4356 skeletal remains were recovered, 3756 of which (86.2%) were morphologically distinguishable. All types of fetal skeletal elements were found, with the exception of some cranial bones. Only 3.4% of individuals could be detected after the cremation process, because of the prevalence of abortions under 12 lunar weeks. All fire alterations were observed and the results were statistically analyzed. This pilot study confirmed the possibility of preservation of fetal skeletal elements after cremation.     

浅析韩国的绿色增长战略

绿色增长正在成为世界谋求经济社会可持续发展的重要经济模式,各国都在寻求实现绿色增长的发展战略。1997亚洲金融风暴、2008年以来的世界性经济衰退促使积极探索经济转型新路的韩国加快了战略转型的步伐。韩国政府为此提出并开始实施“低碳绿色增长战略”,制订并发表了“绿色增长国家战略与五年计划”以及相关的法规,详细阐述了韩国推进这一战略计划的长远规划、战略目标、实施计划、政策措施等,并建立了从中央到地方的组织实施机构。韩国积极推动的绿色增长战略充分揭示了其未来经济发展的基本方向,意在谋求实现经济增长方式的转变、构建未来经济长期稳定发展的新增长模式和动力。     

Public interest law revisited 1

This article undertakes a detailed examination of the practical desirability and legal validity of arbitration clauses under the Nigerian legal regime. This involves navigating through provisions of the relevant Rent Control and Recovery of Premises Law. Areas of incompatibility (including those bordering on jurisdiction, penal provisions and enforcement of awards) between the latter law and arbitration clauses are then discussed. Finally, recommendations are made to the effect that the Rent Control and Recovery of Premises Law should be amended.     

导入ISO9001:2000背景下地方政府绩效考核指标体系述评

地方政府在导入ISO质量管理体系的背景下,其绩效如何考核?国际标准化组织设计了一套完整的指标体系,包括"好政府的制度发展、经济的可持续发展、全面的社会发展和环境的可持续发展"等四个维度。本文对这套指标进行了介绍,并结合中国的具体情况进行了分析,目的在于为地方政府导入ISO质量管理体系进行理论上的指导。文章认为,导入这套指标体系符合我国建设和谐社会和落实科学发展观的要求,有利于促进政府职能转变,有利于解决当前我国的社会问题。因此,它在我国具有相当强的可适用性。     

中美政府人事管理价值的历史演进与比较分析

价值的进路是深入到政府人事管理内核的必由之路。美国政府人事管理价值的历史演进体现了政治回应、道德主义、效率、个人权利、专业的职业化、社会公平等价值,其发展趋势是维护传统理念、加强管理弹性和以结果为本。中国政府人事管理价值的历史演进体现了宗族主义、政治回应、道德主义、公平竞争、分权等价值,其发展趋势主要是法治主义、效率和分权。美国和中国在政府人事管理价值历史演进和发展趋势上呈现了许多共同点和差异。     

Correlation between saw blade width and kerf width

Most studies of saw marks have focused on morphological characteristics and their utility in identifying saws suspected to have been utilized in cases of criminal dismemberment. The present study examined the extent to which metric analysis may be used to correlate saw blade measurements with minimum kerf widths (MKWs). A sample of 56 partially defleshed white‐tailed deer (Odocoileus virginianus) long bones was utilized as proxy for human remains. The long bones were cut using a variety of commercially available saws, including 11 manual‐powered and 5 mechanical‐powered saws. A total of 496 false start kerfs (FSKs) were created. Two experiments were performed, with the first test examining the MKWs of FSKs produced on specimens that were restrained using a bench vise, while the second test analyzed the MKWs of FSKs produced on minimally restrained specimens. Statistical analysis using Hierarchical Linear Modeling (HLM) indicated a positive relationship between saw blade width (mm) and MKW, with blade width (p < 0.001) and the overall difference between the mechanical‐ and manual‐powered saws (p = 0.029) tested, reaching statistical significance. A comparison of MKWs produced using manual‐powered saws on restrained and minimally restrained bones suggests that restraint condition (p = 0.009) has a statistically significant effect. In comparisons of MKWs to blade widths, the average ratio for mechanical‐powered saws is 18.7% greater than the average ratio for manual‐powered saws. While the mode of the ratios was 1.42, thus supporting the general rule that MKW does not exceed 1.5 times blade width, multiple individual ratios did surpass 1.5.     

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.     

Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening at autopsy

Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.     

Homicide by unusual‐edged weapons: Forensic considerations of two cases

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used.
