Treatment Efficacy of Integrative Family and Systems Treatment (I-FAST) With and Without Consultation: The Role of Model Training in the Sustainability of Evidence-Based Family Treatments.

This study examined the efficacy of the Integrative Family and Systems Treatment (I-FAST) training model that seeks to support development of model expertise within the agency in the context of facilitating the sustainability of evidence-based family treatment within community mental health settings. A quasi-experimental design was used to examine treatment outcomes of I-FAST among agencies that received ongoing Consultation and agencies that received No Consultation upon completion of I-FAST training. χ (2) analyses and independent samples t test analyses showed that there were no significant differences between the two groups on clients who had achieved reliable change on Problem Severity and Functioning based on parents' assessments. Significance of this study is discussed in the context of the role of evidence-based family therapy (EBFT) training in facilitating its sustainability in community mental health settings.

Direct amplification of casework bloodstains using the Promega PowerPlex(®) 21 PCR amplification system.

A significant number of evidence items submitted to Forensic Science Service Tasmania (FSST) are blood swabs or bloodstained items. Samples from these items routinely undergo phenol:chloroform:isoamyl alcohol organic extraction and quantitative Polymerase Chain Reaction (qPCR) testing prior to PowerPlex(®) 21 amplification. This multi-step process has significant cost and timeframe implications in a fiscal climate of tightening government budgets, pressure towards improved operating efficiencies, and an increasing emphasis on rapid techniques better supporting intelligence-led policing. Direct amplification of blood and buccal cells on cloth and Whatman FTA™ card with PowerPlex(®) 21 has already been successfully implemented for reference samples, eliminating the requirement for sample pre-treatment. Scope for expanding this method to include less pristine casework blood swabs and samples from bloodstained items was explored in an endeavour to eliminate lengthy DNA extraction, purification and qPCR steps for a wider subset of samples. Blood was deposited onto a range of substrates including those historically found to inhibit STR amplification. Samples were collected with micro-punch, micro-swab, or both. The potential for further fiscal savings via reduced volume amplifications was assessed by amplifying all samples at full and reduced volume (25 and 13µL). Overall success rate data showed 80% of samples yielded a complete profile at reduced volume, compared to 78% at full volume. Particularly high success rates were observed for the blood on fabric/textile category with 100% of micro-punch samples yielding complete profiles at reduced volume and 85% at full volume. Following the success of this trial, direct amplification of suitable casework blood samples has been implemented at reduced volume. Significant benefits have been experienced, most noticeably where results from crucial items have been provided to police investigators prior to interview of suspects, and a coronial identification has been successfully completed in a short timeframe to avoid delay in the release of human remains to family members.

Tracking sperm whales with a towed acoustic vector sensor.

Passive acoustic towed linear arrays are increasingly used to detect marine mammal sounds during mobile anthropogenic activities. However, these arrays cannot resolve between signals arriving from the port or starboard without vessel course changes or multiple cable deployments, and their performance is degraded by vessel self-noise and non-acoustic mechanical vibration. In principle acoustic vector sensors can resolve these directional ambiguities, as well as flag the presence of non-acoustic contamination, provided that the vibration-sensitive sensors can be successfully integrated into compact tow modules. Here a vector sensor module attached to the end of a 800 m towed array is used to detect and localize 1813 sperm whale "clicks" off the coast of Sitka, AK. Three methods were used to identify frequency regimes relatively free of non-acoustic noise contamination, and then the active intensity (propagating energy) of the signal was computed between 4-10 kHz along three orthogonal directions, providing unambiguous bearing estimates of two sperm whales over time. These bearing estimates are consistent with those obtained via conventional methods, but the standard deviations of the vector sensor bearing estimates are twice those of the conventionally-derived bearings. The resolved ambiguities of the bearings deduced from vessel course changes match the vector sensor predictions.

Prescription drug abuse & addiction: past, present and future: the paradigm for an epidemic.

Prescription drug abuse has reached epidemic proportions in the United States and West Virginia is not immune. It is estimated that in 2009, the number of adolescents and adults with a substance abuse and/or dependence problem has reached 23.2 million in the US. There has been an alarming rate of increased sales of methadone, hydrocodone and oxycodone. This article addresses the scope of the problem of prescription drug abuse in West Virginia and the impact by and on the addicted individual. Addiction is a chronic relapsing neuropsychiatric illness manifested by compulsive drug seeking and use. It has created a substantive socioeconomic burden on our state. Prescription drug abuse and addiction increase medical expenses, drug related crime and unemployment. There are misconceptions regarding the etiology and treatment of addiction based on past clinical experience. The view of addiction as volitional misconduct alone has been disproven scientifically. A more current understanding of neurobiological alterations caused by this disease, current treatment strategies and future directions will be presented. This article provides an understanding of prescription drug abuse and addiction's contribution and impact on society's health and social policy. Addressing the problem of prescription drug abuse requires an understanding of the disease of addiction, thus enhancing the effectiveness in diminishing the associated health and social costs. It is the article's intent to illuminate the mutually symbiotic relationship of prescription drug abuse and the disease of addiction and subsequently provide recommendations toward the resolution of this most important issue.
