Duel or Dual: An Interdisciplinary Approach to Parenting Coordination for Uber‐Conflicted Parenting Relationships 下载免费PDF全文
Parenting coordination for families struggling with severe conflict can be challenging for both the family and the parenting coordinator (PC). These families can put an inordinate strain on the PC as they lobby their positions and try to bias the PC against the other parent. The interdisciplinary dual‐PC model is an innovative approach using aspects of the collaborative practice model to enhance the efficacy of the process while utilizing the strengths of both disciplines. Through a case illustration, the identification of the family dynamics and situations that give rise to use of this approach shall become clear. This article also demonstrates the potential benefits to both the family and the PCs. All aspects synthesize into a cohesive, well‐balanced approach to the uber‐conflicted parenting relationships. 相似文献

Simultaneous Identification of Four “Legal High” Plant Species in a Multiplex PCR High‐Resolution Melt Assay, 下载免费PDF全文
Kelly M. Elkins Ph.D. Anjelica C. U. Perez M.S.F.S. Alicia A. Quinn M.S.F.S. 《Journal of forensic sciences》2017,62(3):593-601
The international prevalence of “legal high” drugs necessitates the development of a method for their detection and identification. Herein, we describe the development and validation of a tetraplex multiplex real‐time polymerase chain reaction (PCR) assay used to simultaneously identify morning glory, jimson weed, Hawaiian woodrose, and marijuana detected by high‐resolution melt using LCGreen Plus®. The PCR assay was evaluated based on the following: (i) specificity and selectivity—primers were tested on DNA extracted from 30 species and simulated forensic samples, (ii) sensitivity—serial dilutions of the target DNA were prepared, and (iii) reproducibility and reliability—sample replicates were tested and remelted on different days. The assay is ideal for cases in which inexpensive assays are needed to quickly detect and identify trace biological material present on drug paraphernalia that is too compromised for botanical microscopic identification and for which analysts are unfamiliar with the morphology of the emerging “legal high” species. 相似文献

Re‐investigation of previously unidentified remains from the Korean War has yielded 55 new identifications, each with corresponding records of prior anthropological analyses. This study compares biological assessments for age at death, stature, and ancestry across (i) anthropological analyses from the 1950s, (ii) recent anthropological analyses of those same sets of remains, and (iii) the reported antemortem biological information for the identified individual. A comparison of long bone measurements from both the 1950s and during reanalysis is also presented. These comparisons demonstrate commonalities and continuing patterns of errors that are useful in refining both research on Korean War cold case records and forensic anthropological analyses performed using methods developed from the 1950s identifications. 相似文献

The purpose of this study was to collect data and disseminate trends in officer‐involved firearm deaths in Oklahoma from 2000 to 2015. The Oklahoma Office of the Chief Medical Examiner (OCME) database was searched for civilian decedents with gunshot wounds inflicted by law enforcement officers and officer decedents with gunshot wounds inflicted by civilians. Five decedents were law enforcement officers, while 274 decedents were civilians. The number of civilian decedents throughout the study followed a quadratic trend. Civilian decedents were most commonly males (95%) between the ages of 20 and 39 (64%), had one or two gunshot wounds (46%), and had an increasing number of gunshot wounds over time. Postmortem toxicology testing most commonly detected ethanol, methamphetamine, cocaine, and PCP. Efforts toward increased tracking by various agencies and more scientific studies like this are needed to facilitate future analysis of trends in officer‐involved firearm deaths. 相似文献

While conceptualization of psychopathy has evolved, so too has the public's relationship with psychology changed. Concurrently, portrayal of psychopaths has made several shifts, both through nonfiction sources and in popular film and television. Psychopathic villains of the mid‐20th century have made space for a growing cast of protagonist psychopaths. This study examined whether a relationship existed between exposure to fictional psychopaths and how lay individuals conceptualize psychopathy. Specifically, this study explored conceptualization differences based on exposure to antagonist versus protagonist fictional psychopaths. Surveyed community participants supported earlier research suggesting mixed misunderstanding of psychopathy. Additionally, higher exposure to protagonist psychopaths was associated with higher endorsement of flattering distractor traits, reflecting a kind of romanticized psychopathy. These findings have legal, practical, and ethical implications, including the potential for biased jurors, confounded research about psychopathy's labeling effect, and questions about how psychologists should respond on an individual and systemic level. 相似文献

“Tampering to Death”: A Fatal Codeine Intoxication Due to a Homemade Purification of a Medical Formulation 下载免费PDF全文
Paolo Fais Ph.D. Nicola Pigaiani M.D. Giovanni Cecchetto Ph.D. Massimo Montisci Ph.D. Rossella Gottardo Ph.D. Guido Viel Ph.D. Jennifer Paola Pascali Ph.D. Franco Tagliaro Ph.D. 《Journal of forensic sciences》2017,62(6):1671-1673
Many homemade tamper processes of medical codeine formulations are available on selected “forums” on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called “cold water extraction.” Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above‐mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event. 相似文献

Discharge of a Pistol Out a Car Window with the Breech Within the Interior of the Car: Analysis of Gunshot Residue on a Car's Interior Surfaces 下载免费PDF全文
The defendant, the driver of the questioned car, allegedly extended his right arm over the passenger seat and fired a single shot from a 380 pistol out the passenger window with the pistol's breech within the car. A simulation of this shooting scenario using the same model car, but different year, was conducted to quantitate gunshot residue (GSR) contamination of interior surfaces within the car. The test car's dash and headliner/window frame above the pistol had the heaviest GSR contamination. The dash GSR from airborne deposition documents a firearm discharge within the vehicle. Transfer from GSR‐contaminated hands or clothing to the dash is unlikely. The heavy GSR contamination of the headliner/window frame above the pistol likely documents the window from which the pistol was fired, but additional experiments are needed to verify. 相似文献
