Abstract: Historically, the inability to accurately represent bitemarks and other wound patterns has limited their evidentiary value. The development of the ABFO #2 scale by Krauss and Hyzer enabled forensic odontologists to correct for most photographic plane distortions. The technique presented here uses the ABFO #2 scale in conjunction with the evolving technologies of laser scanners and comparative software commonly used by the automobile industry for three‐dimensional (3D) analysis. The 3D software comparison was performed in which measurements were analyzed of the normal distance for each point on the teeth relative to the bitemarks. It created a color‐mapped display of the bitemark model, with the color indicating the deviation at each point. There was a correlation between the bitemark and the original teeth. 相似文献

With the adoption of statutes, policies and administrative guidance since the late 1980s, statutory child welfare agencies around the world have been implementing practice approaches to resolving and addressing child abuse and neglect concerns that involve extended family systems in decision making and planning. One such approach is the family group conference (FGC), enshrined in New Zealand law. This article provides a historical context and describes numerous provisions of the family group conference that protect participants and the proceedings. It then describes applications of FGC‐like approaches in the United States where practice models and policies—not laws—guide the implementation of such approaches. 相似文献

This article presents the Critical Reading Topics approach, a pedagogical method employed to promote deep thinking in a variety of politics courses. Derived from principles articulated in active learning, critical thinking, backward design, and flipped classroom literature, this method utilizes Bloom’s Taxonomy as the scaffolding for students to create and evaluate pointed and relevant discussion topics written by themselves and their peers. By utilizing this method, faculty can increase students’ contemplation of the course texts, enhance students’ classroom contributions and quickly gauge the extent to which students understand the readings’ main ideas. This approach also enables students to gain authorship of the material, and it gives them additional in-class time to process the complex information they encounter. Evidence collected from six different political science courses is provided to document the approach’s effectiveness. Key findings include an improvement in the quality of relevant and focused discussion topics, a high percentage of students completing reading assignments with corresponding high quiz grades, and significant participation and recognition for all students, even those who are traditionally quiet in class. 相似文献

Abstract: Synthetic cannabinoid agonists are chemically diverse with multiple analogs gaining popularity as drugs of abuse. We report on the use of thin layer chromatography, gas chromatography mass spectrometry, high‐performance liquid chromatography, and liquid chromatography time of flight mass spectrometry for the identification and quantitation of these pharmacologically active chemicals in street drug dosage forms. Using these approaches, we have identified the synthetic cannabinoids JWH‐018, JWH‐019, JWH‐073, JWH‐081, JWH‐200, JWH‐210, JWH‐250, CP47,497 (C=8) (cannabicyclohexanol), RCS‐4, RCS‐8, AM‐2201, and AM‐694 in various commercially available products. Other noncannabinoid drugs including mitragynine have also been detected. Typical concentrations of drug in the materials are in the range 5–20 mg/g, or 0.5–2% by weight for each compound, although many products contained more than one drug. 相似文献
