When analyzing DNA from exploded pipe bombs, quantities are often in trace amounts, making DNA typing extremely difficult. Amplifying minute amounts of DNA can cause stochastic effects resulting in partial or uninterpretable profiles. Therefore, the initial DNA collection from “touch” evidence must be optimized to maximize the amount of DNA available for analysis.This proof-of-concept study evaluated two different swab types with two direct amplification strategies to identify the most effective method for recovering DNA from common pipe bomb substrates. PVC and steel pipes, electrical tape, and copper wire spiked with epithelial cells were swabbed with cotton or microFLOQ® Direct Swabs and amplified directly or via a pre-treatment prior to STR amplification.Not only was the microFLOQ® Direct Swab protocol the quickest method with the least risk of contamination, but in combination with direct amplification, the microFLOQ® Direct Swabs also generated the most complete STR profiles. 相似文献

Since 1995, Pennsylvania's Balanced and Restorative Justice Mission has been the driving force behind Pennsylvania's reform and system improvement efforts. Pennsylvania has made strong and steady progress towards advancing this statutory mission and the related operational goals through policy, practice and programmatic enhancements over these past 20+ plus years. Three key events spurred forth this advancement: the legislative passage of Act 33 in 1995 that statutorily established the goals of Balanced and Restorative Justice (BARJ), the Models for Change Juvenile Justice Reform Initiative–Additional Reform Momentum (2004) and the Juvenile Justice System Enhancement Strategy–Evidence‐based Approach to the Reforms (2010).What follows is the story of how it all unfolded. 相似文献

On December 21, 2018, the Juvenile Justice Reform Act was signed into law, marking the first update in 16 years to the Juvenile Justice and Delinquency Prevention Act of 1974, as amended. The reforms reflect much of the knowledge that has been gained through research and science over the past decade and strengthen the Act’s core protections for youth in the juvenile justice system. The changes also expand the Office of Juvenile Justice and Delinquency Prevention’s role in research, and technical assistance, and provide for additional oversight for related programs. 相似文献
