Explosion Scene Forensic Image Interpretation

Image interpretation is an important aspect in the field of forensic science; however, it is seldom reported how to use these techniques in explosion scene forensic investigations. On 12 August 2015, a series of explosions killed 165 people and injured hundreds more at a container storage station at the Port of Tianjin. In this study, we applied image interpretation methods to determine the seat of the explosion by analyzing low‐quality video clips of the event. The interpretation fits well with recently published standard operating procedures, including the hypothesis, evaluation, inference, and confirmation. Image processing was adopted to enhance the images while the explosion scene was reconstructed with the same images. Some important features were extracted and utilized to distinguish whether the flashes were caused by reflection or a real blast. We reveal the real explosion location, which guides the overall investigation. The results indicate that image interpretation is a powerful tool for forensic investigators to analyze low‐quality images in complicated explosions or fire accidents.     

Effect of History and Context on Forensic Pathologist Interpretation of Photographs of Patterned Injury of the Skin

In a previous study, a survey‐based analysis of pathologist diagnoses of patterned injury was performed. Subjects were provided with photographs of “classic” injuries and asked to diagnose the lesion in the absence of history or context. There was a relatively low diagnostic consensus among respondents. A second survey suggested that the disparate answers were not due to a strong belief in different diagnoses, but instead reflected how the respondents dealt with ambiguity. A third survey was created that asked participants to evaluate patterned injuries of the skin, but provided history and contextual information. The addition of history and contextual information increased consensus from a median of 80% to 98% on a per‐question basis. Confidence increased from a median of 56%–92%. These results demonstrate the importance of history and context in medical diagnosis of patterned injuries of the skin.     

Ancestral Variation in Orbital Rim Shape: A Three‐Dimensional Pilot Study

Traditional nonmetric methods of ancestry assessment posit orbital rim shape varies among ancestral groups. This pilot study uses morphometric analysis of 3D orbital variation to test discrimination among individuals of primarily European, African, and Asian ancestry. Although the size and nature of the sample analyzed limit inferences for other samples, principal components analysis suggests ancestry has a significant effect on rim shape (p = 2.93e‐04). European orbits display more marked folding of the orbit in the sagittal plane than either African or Asian orbits, while the lateral margin of African orbits lies further posterior relative to the medial margin when compared to Asian orbits. The findings suggest curviplanar relationships are the most ancestrally informative aspect of orbital rim shape; these relationships may be distorted by perspective based on orientation of the skull relative to the viewer in traditional nonmetric analyses. Additional studies on geometric morphometric approaches to ancestry assessment are therefore warranted.     

陕甘宁边区的民事立法及其对当代民法典编纂的启示

发轫于战争特殊时代的陕甘宁边区民事法律,是边区法律制度的重要组成部分。民国六法全书、中共的政策、边区民事立法、民事习惯构成了边区民事法律的主要渊源。中共领导了边区民事立法,体现出民主立法、与时更进、因地制宜等特征,深入分析边区民事立法的基本经验,有助于推动当代中国民法典的编纂。     

Evaluation of maxillary sinus dimensions in gender determination using helical CT scanning

Gender determination is an important step in identification in forensic medicine. CT measurements of maxillary sinuses may be useful to support gender identification. This study was undertaken to study the accuracy and reliability of maxillary sinus dimensions measurement in gender classification through the use of reconstructed helical CT images. Eighty-eight patients (43 men and 45 women) with age range from 20 to 49 years were selected in this study. The width, length, and height of the maxillary sinuses in addition to the total distance across both sinuses were measured. Data were subjected to discriminant analysis for gender using multiple regression analysis. Maxillary sinus height was the best discriminant parameter that could be used to study sexual dimorphism with an overall accuracy of 71.6%. Using multivariate analysis, 74.4% of male sinuses and 73.3% of female sinuses were sexed correctly. The overall percentage for sexing maxillary sinuses correctly was 73.9%. It can be concluded that reconstructed CT image can provide valuable measurements for maxillary sinuses and could be used for sexing when other methods of sexing are not conclusive.     

视频图像侦查中涉案目标消失的原因分析与应对

在视频图像侦查过程中,经常会发生视频追踪对象在某个特定区域的视频监控图像中＂消失＂的现象。它可能是由于存在监控盲区造成的,也有可能是由于犯罪嫌疑人的反侦查行为,或者侦查员在视频监控资料收集、处理、查看过程中存在问题造成的。因此,我们可以通过合理布局,减少监控盲区,广泛收集和处理视频监控资料,深入查看和分析视频消失区域,多种侦查手段并用等途径来加以应对。     

间断—平衡模型：长期政策变迁的非线性解释

政策变迁并非只是渐进的过程,重大的政策转变和政策中断也时常发生。以逻辑经验主义为基础的渐进主义模型只强调政策的渐进性变迁,而忽略政策的间断性变迁。建立在库恩科学范式基础上的政策研究不仅关注政策的渐进性变迁,而且也关注政策的间断性变迁。＂间断-平衡模型＂建立在有限理性决策和制度结构基础上,认为政府政策制定具有稳定性和间断性的特点。该模型有效解释了长期政策稳定过程中伴有偶尔急剧变迁的现象,为长期政策变迁提供了新的解释框架。本文介绍了＂间断-平衡模型＂的缘起、理论基础、核心观点、解释过程等几个方面,最后对模型进行简要评述。
