Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.
Key points
- Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
- Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
- These metrological principles also apply to individuation of unique objects in general.

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm3) than in controls (mean 2 342 cm3). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD. 相似文献

Being placed in restrictive housing is considered one of the most devastating experiences a human can endure, yet a scant amount of research has been conducted to test how this experience affects core indicators of prisoner reentry such as employment and recidivism. In this article, we use Danish registry data, which allow for us to link penal conditions to postrelease outcomes, to show how the reentry outcomes of individuals placed in disciplinary segregation, which is placement in restrictive housing because of disciplinary infractions, compare with those sanctioned for in-prison offenses but not placed in segregation. The results from matched difference-in-differences analyses show that Danish inmates placed in disciplinary segregation experience larger drops in employment and larger increases in the risk of being convicted of a new crime in the 3 years after release from a correctional facility than do Danish inmates who were sanctioned for a serious offense but not placed in disciplinary segregation as a result. Because being placed in disciplinary segregation, and restrictive housing more broadly, is so common, these results indicate that restrictive housing placement may be a key moderator of the effects of incarceration that merits more attention from criminologists, provided the associations shown here represent causal effects and generalize. 相似文献

Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone. 相似文献

文章为谁而写,是法学研究需要解决的基础性命题。从近二十年约2.5万篇法学核心期刊文章的大数据机器学习分类结果看,我国的法学研究成果呈多重目标格局,其中近三成服务于执法机关(包括行政机关和司法机关),同时也有为立法者、执政者建言献策的成果。经检验,目标受众类型的选择与论文的传播能力以及获得基金支持的机会之间有显著相关性。这一决定成果影响力大小的机制迟早会被个体习得并不断强化,成为研究者选择目标受众类型的重要因素。该机制良性运转的关键是处理好学者和实践受众的关系,保持学术研究必要的自主性,警惕学术研究在追逐发表、经济支持时被有关主体“认知俘获”。 相似文献

The regulations of cross-border data flows is a growing challenge for the international community. International trade agreements, however, appear to be pioneering legal methods to cope, as they have grappled with this issue since the 1990s. The World Trade Organization (WTO) rules system offers a partial solution under the General Agreement on Trade in Services (GATS), which covers aspects related to cross-border data flows. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the United States-Mexico-Canada Agreement (USMCA) have also been perceived to provide forward-looking resolutions. In this context, this article analyzes why a resolution to this issue may be illusory. While they regulate cross-border data flows in various ways, the structure and wording of exception articles of both the CPTPP and USMCA have the potential to pose significant challenges to the international legal system. The new system, attempting to weigh societal values and economic development, is imbalanced, often valuing free trade more than individual online privacy and cybersecurity. Furthermore, the inclusion of poison-pill clauses is, by nature, antithetical to cooperation. Thus, for the international community generally, and China in particular, cross-border data flows would best be regulated under the WTO-centered multilateral trade law system. 相似文献

我国刑事错案追究制度自实行以来,其运用的合理性以及有效性一直饱受争议。从侦查机关的视角考察,错案追责情况主要存在纠正程序不具体、追责程序透明度不高等相关问题。结合我国实际情况考虑,从内部制度与外部监督入手考虑设立独立的错案追究机关来进行解决是可行的,同时可从细化错案责任追究的相关程序、明晰实体责任性质的认定标准、建立健全办案质量终身责任追究制度和建立追责程序相关信息发布机制等方面来完善刑事错案追究制度。 相似文献
