Transferring MSW Education to Practice: A Qualitative Study With Public Child Welfare Employees

This study used a qualitative analysis of survey data collected from public child welfare employees (n = 168) as they completed master's of social work courses in a weekend/hybrid program, to examine their perceptions of ability to apply classroom learning to practice. The program, which combined a focus on direct practice and management, was developed in partnership with the state's public child welfare agency, during a period of systemic change and case practice reform. Findings indicate that students readily transferred knowledge and skills to the workplace, albeit with some challenges. In particular, management courses appeared to provide an important framework in understanding the organizational context of practice.     

Formative Evaluation of an Evidence-Based Intervention to Reduce Long-Term Foster Care: Assessing Readiness for Summative Evaluation

As part of the federal Permanency Innovations Initiative, this local grantee implemented an evidence-based intervention to improve outcomes for children with serious emotional disturbance. The project approach integrates the tenets of implementation science and program evaluation. Formative evaluation used a small sample (n = 76) to assess implementation integrity and statistical association to recommend whether the intervention was ready for summative evaluation (SE). Results showed that most process expectations were met. Statistical findings suggested that the intervention was associated with higher rates of reunification for treatment families as compared to families receiving services-as-usual. Thus, the intervention was recommended for SE.     

Cloud Data Imager: A unified answer to remote acquisition of cloud storage areas

The pervasive availability of cheap cloud computing services for data storage, either as persistence layer to applications or as mere object store dedicated to final users, is remarkably increasing the chance that cloud platforms potentially host evidence of criminal activity. Once presented a proper court order, cloud providers would be in the best position for extracting relevant data from their platforms in the most reliable and complete way. However, this kind of services are not so widespread to date and, therefore, the need to adopt a structured and forensically sound approach calls for innovative weaponry which leverage the data harvesting capabilities offered by the low level program interfaces exposed by providers. This paper describes the concepts and internals of the Cloud Data Imager Library, a mediation layer that offers a read only access to files and metadata of selected remote folders and currently supports access to Dropbox, Google Drive and Microsoft Skydrive storage facilities. A demo application has been build on top of the library which allows directory browsing, file content view and imaging of folder trees with export to widespread forensic formats.

The Analysis of a World War I U.S. Service Member's Dental Remains Recovered in France

In October 2009, the grave of an unknown World War I (WWI) U.S. service member was exhumed in Rembercourt‐Sur‐Mad Village, in the Lorraine Region of France. The skeletal remains and material evidence were accessioned into the Joint POW/MIA Accounting Command's (JPAC) Central Identification Laboratory (CIL). The personnel records for the associated casualty were requested, received, and reviewed. A dental profile was present among the service member's personal information. There were multiple points of concordance between the dental records of the associated casualty, and the recovered dental remains to include eight restored teeth, 15 unrestored teeth, and three antemortem missing teeth. Distinctive restorations which compared favorably included a porcelain crown and multiple gold foil fillings. All lines of evidence (historical, material evidence/personal effects, anthropological, and dental) and the circumstances of loss compared positively with the associated casualty. On April 1, 2010, the previously unaccounted‐for U.S. service member was positively identified and on June 23, 2010, was buried with full military honors at Arlington National Cemetery.     

Quantification of psilocin in human whole blood using liquid chromatography–tandem mass spectrometry (LC–MS/MS)

There has been burgeoning interest in psilocybin-use for the treatment of various neurological and neurodegenerative diseases. Psilocybin is mistakenly perceived as the principal pharmacologically active compound due to its high concentrations found in magic mushrooms; however, it is the prodrug of psilocin. Despite the expanding body of clinical research seeking to understand the pharmacodynamic/pharmacokinetic properties of psilocin, and its role in inducing dramatic changes to cognitive function, there has not been a corresponding increase in the development of sensitive analytical methods that can quantify psilocin in different biological fluids. Existing analytical methods have been developed using plasma, serum, and urine as the matrix of choice, but with the unknown blood-to-plasma ratio of psilocin, any pharmacokinetic conclusions drawn solely on plasma data may be misleading. Thus, the main objective of this study is to develop the first analytical method that utilizes SPE and LC–MS/MS to quantify psilocin in human whole blood. The SPE procedure yielded a high recovery efficiency (≥89%) with minimal matrix effects. The method was validated according to ANSI/ASB 036 guidelines. Linearity was between 0.7–200 ng/mL and encompassed previously reported ranges found in plasma/serum. Bias, within- and between-run precision for all quality controls met ANSI/ASB 036 acceptability criteria. Endogenous/exogenous interferences and carryover were negligible. Psilocin stability was assessed at 4°C over 48 h and was considered stable. Although a proof-of-concept study will need to be performed to characterize the method, this analytical workflow was able to detect and quantify psilocin in human whole blood at low limits of quantification.     

Volume Determination of Fresh and Dried Bloodstains by Means of Optical Coherence Tomography

The volume of bloodstains found on crime scenes may help forensic investigators reconstruct the location and kinematics of bloodletting events, as stain size, volume, and impact velocity are related. Optical coherence tomography was used as a method to determine the volume and volume ratio of dried and fresh bloodstains on both glass and irregular surfaces or deposited with an impact velocity. The volume of blood drops deposited on smooth glass surfaces was measured within a deviation of 2%. This deviation increased for droplets on irregular surfaces or deposited with an impact velocity. The volume ratio of dried and fresh bloodstains was equal to 19–28% depending on the individual donor and on the use of an anticoagulant. Optical coherence tomography is a good method to determine the volume of fresh and dried bloodstains in laboratory conditions and allows accurate determination of the dry/fresh ratio.
